The usual dimensions of LEGO bricks are 250 x 125 x 65mm. The standard product has 2 holes with a diameter of 65mm, they are located at a distance of 60mm from each other. The main advantage of the product is the simplicity of masonry, performed according to the principle of connecting holes with spikes protruding from the front of the brick. The height of these spikes must be exactly 5mm, otherwise it will not be possible to implement a masonry concept that provides the operational advantages of the product.

(function(w, d, n, s, t) ( w[n] = w[n] || ; w[n].push(function() ( Ya.Context.AdvManager.render(( blockId: "R-A -388243-6", renderTo: "yandex_rtb_R-A-388243-6", async: true )); )); t = d.getElementsByTagName("script"); s = d.createElement("script"); s .type = "text/javascript"; s.src = "//an.yandex.ru/system/context.js"; s.async = true; t.parentNode.insertBefore(s, t); ))(this , this.document, "yandexContextAsyncCallbacks");

Precise laying, possible with correct location holes, relative to the side edges. The distance from the edge to the center of the hole on the outside should be 30mm, which will allow the bricks to be laid in even rows. The corners of the brick are 15mm in size, if the indicator is larger, then the product loses its aesthetic appeal. The indicated dimensions of LEGO bricks are relevant only for a standard product, however, there are many other types on the market, mainly made with imported matrices.

Thickened and elongated bricks

The most popular dies (press LY1-10):

• SHAFT MASSIVE;
• MODULAR MASSIVE;
• CONVENTIONAL MASSIWE.

Using these matrices, bricks are made different shapes, but they all have the same size - 250x125x100mm. Such products are slightly higher than standard samples produced on domestic equipment, therefore, fewer bricks are needed to complete the masonry, and this is a direct saving. There are samples that have a size of 300 × 150 × 100, however, such products do not have holes, in the center they have a recess along the entire length, a groove protrudes from one side, and a spike from the other.

Possible dimensional deviations during production

The dimensions of LEGO bricks are of decisive importance for manufacturers, expanding the range, they increase the competitiveness of products, as they provide consumers with more options for building. The main task of the manufacturer is the correct adjustment of the machine, on which the uniformity of the brick geometry depends. The thickness of the product on one side can be less by 1.5 - 2 mm. You can fix this by using the adjusting bolts equipped with support nuts. By properly adjusting the machine, you can produce bricks of the desired size.

The technical characteristics of the product are 80% dependent on the formula of the mixture of LEGO bricks. The key raw material is quarry screenings obtained as a result of the development of...

Original thinking always leads to unexpected results, for example, to the question, how can a brick be improved? One Dane named Ole Kirk put forward his idea. He came up with a design that made it much easier to lay bricks. Everyone knows the Lego constructor, in which the parts are rigidly connected to each other thanks to round recesses. So the inventor decided to give a similar form to an ordinary brick bar. As a result, this idea took root and spread widely, today Lego bricks are widely used in construction. What are its advantages and features, we will consider today in the article.

Lego brick: design and specifications

As you already understood, the lego brick has round bulges, usually there are two of them. Thanks to them, such a brick lays down immediately as needed. With this design, there is no need to adjust the bricks in any direction. Such a brick is suitable for the construction of partitions, and for the construction bearing walls.

Brick dimensions are 250 x 125 x 45-80mm, weight varies in the range of 3.5-4 kg. It is worth saying that the Lego brick has not just bulges, it has two round holes, each with a diameter of 65 mm.

This material is frost-resistant and withstands more than 200 freezing and thawing cycles.

Structure density 1550 kg/m3

Thermal conductivity 0.4-0.45 W/(m K);

Advantages and disadvantages of lego bricks

As already found out, a clear advantage of Lego bricks is simplified installation. He lays down himself, as required by the technology of building walls. And this reduces the time of its installation and it requires less effort. All this affects the quality of the walls, they turn out to be even, more stable during the seismological movement of the soil, since each individual brick is connected to the entire wall not only with mortar, but also with a special compound.

The undeniable advantages include the possibility of unhindered laying of communications inside such a wall due to the presence of holes.

Aesthetically smooth surface and a variety of colors allow you not to use finishing materials for the walls of the house, erected from Lego bricks.

The only disadvantages are the fact that it appeared relatively recently and there is no exact data on how it behaves during prolonged use, moreover, at the moment there are no certified Lego brick manufacturers.

Lego brick mix

Such a brick can be made by anyone who purchases a machine for its production. In this case, mixtures can be used in three types:

• Sand-clay-cement is produced in proportions of 35% / 55% / 8%
• Clay-cement composition: 90% / 8% /
• Based on Dropouts: 90%/8%

All of them are diluted with water to the desired consistency.

Two detailed prescription mixtures:

• 70% - limestone - screenings
• 10 - fine limestone
• 11% - cement "pc 500"
• 4% - coloring pigment
• 5% - silica fume - performance enhancer

Second recipe:

• 85% - limestone
• 12% - cement pts 500
• 3% - coloring pigment

Such a brick is made using a special machine. If you have the appropriate raw materials and with the help of such equipment, you can easily make Lego bricks with your own hands, since many machines operate in automatic mode.

Application area

As mentioned above, lego bricks are suitable for building any type of wall. Therefore, the range of its application is quite wide. Not only a house can be built from it, but also outbuildings: a garage, a utility block, a gazebo. It is also suitable for the construction of entire fences and its parts - pillars. Beautiful appearance allows it to be used as facing material, both outside the house and in the interior. In addition, brick in the interior is very popular today, so it is not uncommon for Lego bricks to be used in redevelopment. From it, partitions are more reliable than from drywall, and besides, such a wall does not need additional design.

How to lay lego bricks

Installation of Lego bricks will not cause difficulties even for a beginner, because he is assembled as a constructor, no special skills are required when laying it. Since each brick is strictly profiled, it will not be possible to lay it incorrectly. The installation of such a brick differs from the usual one in that a special adhesive is used for its installation instead of cement mortar. Although, for greater reliability, some craftsmen recommend concreting and reinforcing the cavities of brick rows.

When using glue, its consumption is 25 kg per 500 bricks

The only difficulty may arise when laying the first row, installation is carried out using a level and strictly along without deviations to the sides.

Thanks to the original profile, the installation of Lego bricks is carried out 2-3 times faster than the traditional one.

The Lego brick has not yet found wide application in Russia, it has not been sufficiently studied and is even little known to many professionals, although the invention of the Danish builder Ole Kirk is already over 100 years old. The main obstacle is the lack of knowledge of properties in the long term, which scares away branded manufacturers. And most garages are not concerned with obtaining quality certificates.

The appearance of the material resembles the details of the same name children's constructor. The product has two spherical guide holes with protrusions on one side and recesses on the other, acting as a kind of lock with a clear stacking geometry. Laying Lego bricks using the tongue-and-groove method is easy to execute at high speed. The material can be successfully used in all areas of application of traditional bricks. Standard dimensions are 250×125×65 mm or 300×150×100 mm, with a weight of 3 to 4 kg.

Manufacturing technology

Making Lego bricks includes the following steps:

1. Preparation of raw materials, their sorting and preparation of the desired mixture.
2. Mixture shaping.
3. Pressing products.
4. Storage of finished bricks.
5. Exposure a certain time before use.

For production, special equipment is required, consisting of the following units:

• loading bunker;
• mixture dispenser;
• a molding chamber with a special matrix located in it;
• electric motor;
• hydraulic press with oil pump.

All equipment is attached to metal frame and takes up little space.

When manufacturing products in large volumes, it is recommended to have additional devices for sorting, sifting and mixing raw materials, as well as a conveyor for feeding the mixture into the receiving hopper.

The process consists of the following operations:

• sifting and grinding components;
• thorough mixing of the components;
• dispenser sends desired volume into the molding chamber, where the product is molded with the help of a matrix;
• pressing the mixture under pressure generated by the oil pump;
• the finished brick is pushed out by the ejector;
• storage of bricks in a warehouse and exposure to shipment to consumers ≥ 3 days.

Brickwork is made after the manufacture of products after 21 days.

Preparing the mixture

What are Lego bricks made of?

The quality of products depends on the dosage and the type of components in the mixture.

The composition of the mixture for lego bricks:

• binder (cement and clay);
• fillers (sand or various non-solid screenings);
• plasticizers;
• coloring pigments;
• water.

Clay-cement compositions contain up to 10% cement, 80 ... 90 clay.

Higher quality mixture of up to 15% Portland cement and screenings 85 ... 90.

Lego brick composition mixes may contain fillers from a variety of available local screenings from development rocks:

• shell rock;
• limestone;
• marble;
• dolomite;
• travertine;
• other soft rocks.

When laying bricks, frost-resistant types of glue are used to ceramic tiles applied with a special gun, roller or brush (you can use plastic bottle, through which the glue is squeezed out).

Various cables and wires can be passed through the holes, reinforcement and concreting can be carried out.

The material has excellent technical and physical characteristics, so the strength is 1.5 times higher than the ceramic counterpart.

Cons of lego bricks:

• lack of GOST and unified normative documents for production;
• has not passed a sufficient test of the durability of the use of technology;
• the matrix should be made only from high-quality steels (for example, 40X).

There is no doubt that in the near future, Lego bricks will compete with traditional types of bricks.

When it comes to Lego bricks, it is very difficult to separate the seeds of popularization of a new product from its real working qualities. Even the term itself, using the name of a well-known toy company, does its best to simplify concepts, which is not always beneficial. Especially when it comes to professionals or advanced amateurs.

To dispel the childish image of a wonderful building product a little, let's call a spade a spade.

So, the term Lego brick, literally translated from English, sounds more detailed and complete - interlocking brick, which means interlocking bricks, blocking brick, that is, a brick with a lock.

Now, when discussing and searching for information regarding price, characteristics and application technologies, the possibilities are significantly expanding, especially for those who decide to make a Lego brick with their own hands.

Simplicity and financial benefit

Why is a house built of Lego bricks so good? Of course, simplified styling technology. Indeed, if we touch on this very costly aspect of any construction, then the savings in time, and with it paid man-hours, during the erection of the walls of a building structure are significantly smaller. Added to this is the aspect that the number of highly paid professionals can be kept to a minimum.

This does not mean that botanists will build a house for you in their free time, a professional bricklayer is still needed. But with the main work, such as: lifting the material, laying straight sections, mixing glue and applying it, sane handymen or students can do it. Their prices are several times lower than those of professionals, and the quality of work when laying Lego bricks will still be on top.

Well, and if the amount of work is small, or the construction time is not of fundamental importance, you can always try to do everything yourself. Here, in addition to reducing cash costs, the pleasure of the work done and the result is also added.

If we turn to the technology of making Lego bricks, and not go into details of the composition and proportions of the mixture from which it is produced, a very simple circuit. We have a filler - sand, screenings, shell rock and a binder, cement. All this is thoroughly mixed, water, plasticizers and other chemicals are added, after which, using a matrix and a press, this mass is molded according to the planned dimensions.

As a result, after a short drying, we get bricks of various strengths and appearance, which, depending on the technical and decorative indicators, are used for the construction of load-bearing walls, interior partitions, recessed structures, and so on. In principle, wherever an ordinary brick is used, the only difference is that there are much more types of pressed Lego bricks.

Lego brick laying features, or a fast-paced start-up for novice builders

At the beginning of this article, it was no coincidence that we were ironic about botanists. In no way did we mean to offend anyone, but the events recent years due to financial shocks, people are increasingly being driven from their jobs, forcing them to look for themselves in new, more profitable and in-demand industries. One of these niches was and remains construction, in particular, the work of a bricklayer.

It is hard to imagine that waking up in the morning on a difficult Monday, a person decides to pick up a trowel and immediately begin to give out highly paid volumes. To become a qualified bricklayer, you need to expel more than a dozen cubes under wise guidance, make and fix a bunch of "jambs", spend a lot of time and effort. Lego-brick will help the beginner save this resource and quickly move from the rank and file to the honorary officer corps.

The fact is that it is almost impossible to lay an interlocking brick unevenly. You just need to learn a small theoretical part, be careful and diligent. Everything else will happen almost without your participation.

Here is a short video that clearly explains the main aspects of laying Lego bricks.

So what do we see? In a short period of time, a nimble Malaysian worker laid 154 bricks to peppy music. At standard sizes 250x125x65 of one piece we have 0.3 cubic meters of masonry. The prices for masonry are different on the territory of our vast country, but for a basic minimum, you can take, for example, 2000 rubles per 1 cubic meter. It turned out - about 600 rubles of earnings. Not bad?

The most difficult and responsible thing is to lay the first row, it requires the exact level and correction of each brick. When erecting a building box, such a place will be the corners of the future building. If there is no experience, it is better to entrust this matter to a professional. But then you just need to follow the laying scheme, do not forget about reinforcement and embedded elements - things will go much more cheerfully.

Of course, it is impossible to grasp all the details of building walls on the fly, but with the desire and due perseverance, the learning process, and with it the paid or saved result, will come much faster.

Comparison of technical characteristics. Lego brick vs classic

On the net you can find many opponents of Lego technology leaving negative reviews. But take a closer look - basically all the shortcomings of the Lego-brick are far-fetched and have nothing to do with practice. Most likely, these are the same professionals who are terribly upset by the price cuts and the arrival of new people in their business. Let's compare the Lego brick with the usual burnt counterpart in terms of the main technical indicators.

Data taken from open sources. As a starting point, we took the strength of the brick. It can be different depending on the production technology. M150 is the recommended minimum strength for the construction of load-bearing structures.

What conclusion can be drawn from this blitz analysis?

1. With the same strength, the weight of a Lego brick is less. This means that the cost of lifting the material to the place of work falls, and the structure itself will be lighter. This, in turn, reduces the requirements for the overall bearing capacity of the structure, which will ultimately reduce the cost of the project as a whole.
2. The water absorption of the pressed lego-brick is 2.5 times less than the usual one. This means that its service life in an unstable winter climate middle lane will be greater, and in the room with the same ventilation schemes, the humidity will be lower.

Otherwise, everything is the same, which means that there are no special obstacles to the use of Lego bricks.

Now a few words about the price at which you can actually buy one and the other material. At the factory, it will be approximately the same and will be from 10 to 15 rubles apiece. But talk about cost without regard transport costs and the cost of unloading and loading operations will be incorrect. These are inherent associated costs that need to be calculated based on the conditions in which the construction takes place.

Therefore, it is difficult to analyze here, but ceteris paribus brick-lego has one undeniable advantage– it can be manufactured directly at the facility, thereby significantly reducing all associated costs and time. Yes, this is not a reservation, in the season there is a queue for bricks at the factories, but this is simple and garbage in terms of time.

Lego brick with your own hands. Brief overview of equipment and manufacturing technology

Before thinking about the organization of production, you need to accurately weigh the pros and cons, including cost and cost data in the analysis. The first and foremost thing to understand is the scope and organization technological process. Brick production is not a garage-sized occupation. This process is large-tonnage, requires large production areas and verified logistics for the supply of material and the delivery of finished products. This is when it comes to business.

If you make Lego bricks for yourself, you need to calculate the profitability of this venture based on the volume of your construction site and the cost of production at the construction site.

According to the standard technology for making Lego bricks, the following composition and proportions of the mixture are recommended:

1. Sand - 10%
2. Screening of crushed stone - 70%
3. Cement M500 - 20%

Cost of materials:

1. Sand - 520 rubles / tn
2. Screening - 185 rubles / ton
3. Cement - 175 rubles / bag

Consumption and estimated cost per 1 ton of mixture

1. Sand - 52 rubles
2. Screening - 130 rubles
3. Cement - 700 rubles

From 1 ton of the mixture, 285 bricks are obtained. The cost of purchasing materials - 882 rubles. The cost of one unit is 3 rubles 09 kopecks. The number of ready-made Lego bricks per shift is from 900 to 4000 pieces in 8 hours (depending on the power of the machine).

The cost does not include:

1. Possibility to buy bulk cement, which is much cheaper
2. The cost of the plasticizer, they are different in terms of consumption and efficiency. This needs to be analyzed separately.
3. The cost of transport services for the delivery of materials
4. Workers' wages
5. Depreciation and maintenance of equipment
6. The cost of electricity if the press is not manual

Equipment for the production of Lego bricks on the Russian market is presented in a wide range. The simplest and cheapest solution to the problem is hand press for molding and a small concrete mixer. The cost of this device will be in the region of 45-65 thousand rubles. Of course, one cannot count on serious production volumes in manual mode, here we are talking about 500-800 pieces per shift with intensive work with a partner.

The obvious advantages of manual equipment are low cost, compactness, mobility and the possibility of passing use. For example, having on the farm manual machine for the production of Lego bricks, you can provide yourself with briquettes for heating from sawdust.

The cost of equipment directly depends on the force that the press produces and the amount of automation that speeds up the production process. Also, the higher this indicator, the better the output will be. The cost of such a configuration starts from 200 thousand rubles for a simple hydraulic press with a capacity of 1,500 pieces per shift and reaches 7-8 million for complete lines with an output of up to 10,000 products per shift.

Semiautomatic machine

Serious manufacturers offer services for the calculation and preparation of a business plan for such industries, develop mixture formulations based on local conditions, and provide technical support to the manufacturer at all stages of operation.

High performance automatic equipment

The meaning of this article is not limited to advertising individual manufacturers and does not provide a one hundred percent solution for getting rich quick. Here we tried to formalize the idea, the direction of a dream for a person with an active lifestyle. Reviews on numerous forums are also not the ultimate truth, here you can easily get to advertising tricks, sometimes not giving real information.

The main thing is to show perseverance, common sense and purposefulness, and the rest will follow and will definitely work out.

The production of lego bricks (as the new construction material) increases every year. This type of building material for walls does not require firing, which means that its production can be started at home by purchasing necessary equipment and technology. According to experts in the construction market, Lego brick is steadily expanding its niche, attracting more and more new admirers.

Why Lego?

The name of the material for the walls comes from the popular children's designer. Brick, or block, though bigger size, outwardly very similar to the details of the designer from Lego.

In the manufacture of this material, hyper-pressing of the finished mixture is used, consisting of screenings of limestone rocks, Portland cement and water. The main composition of Lego bricks is of 2 types: cement-clay and cement-clay-sand.

Products made using this technology have special formation grooves, which speed up the construction of building walls or fences.

In the construction market, Lego bricks are classified according to different parameters. By the size of technological openings:

• hollow model (holes occupy 25% or more of its area);
• full-bodied model (it has a hole area of ​​less than 25%).

By lock type:

• restriction in 2 directions - horizontally and transversely;
• limited only in the transverse direction.

In appearance:

• smooth face;
• textured.

Classification according to the type of connection of bricks in the masonry:

• T&G (tongue and groove);
• P&D (protrusion and recess);
• topological lock.

Most Lego products are produced with locks of the first two positions. In the manufacture of Lego bricks involved in high-rise housing construction, a sand-cement composition is used in a ratio of 1:10.

Production process and composition of the mixture

The following manufacturing technology is used in the production process:

• crushing and screening the components of the mixture;
• dosage and mixing of the components that make up the solution;
• molding;
• high pressure pressing.

Lego brick factories use the following compositions for its manufacture.

1. Cement + clay. The percentage is expressed as follows: 80-90% clay, 10% cement, 3% water.
2. Cement + clay + sand. The components are mixed in such quantities: 50-60% sand, 30-40% clay, 10% cement, 3% water.
3. Limestone sawing screening - 75-80%, Portland cement - about 15% and water.

A mixture based on limestone is considered the highest quality; products made from them are used to build load-bearing walls.

For Russian climatic conditions, mixtures of screenings of crushed stone with dyes and cement in a proportion of 8-20% are more suitable. The mixture is pressed under high pressure to obtain high quality blocks.

The composition of the mixture for Lego bricks also includes such materials:

• pigments;
• plasticizers.

Pigments are used to give products different color shades, which improves their appearance. For the manufacture of Lego bricks, used in the construction of buildings with increased requirements for moisture permeability, plasticizers are added.

Advantages and disadvantages of the material

The advantages of the material include:

• brick production without firing;
• increase in productivity when laying walls;
• beautiful appearance;
• accuracy and ease of masonry;
• lighter weight of products, which reduces the load on the bricklayer;
• the ability to use through holes in the blocks for communications;
• high frost resistance, the material tolerates 30 freezing cycles well;
• good wear resistance, no cracks and chips, which reduces the percentage of waste;
• environmental friendliness;
• fire resistance;
• high moisture resistance;
• the use of special glue when laying walls, which is much cheaper than cement-sand mortar;
• variety of shades and textures;
• a perfectly flat surface of the material is the basis of the same even walls;
• cost savings due to the use of adhesive as a binder.

With such an impressive list of advantages, Lego bricks also have disadvantages. You can highlight the following:

• relatively low heat saving coefficient;
• the use of expensive matrices made of high-quality steel;
• high sorption moisture content of the material.

To get high-quality Lego bricks, the composition of the mixture should be formed according to the pressure of the press available in the production. For soft limestone rocks, the minimum pressure must be at least 170 kg/cm².

Production equipment

The main equipment for the production of Lego bricks is special machines. They are manual (for making bricks at home) and high-performance electric, the purchase of which allows you to open a medium-sized business.

Machine classification:

1. Do-it-yourself lego brick making machine. Productivity 1000 pcs. for a shift. They are manual and electrically operated.
2. Machine tools for individual production of the middle category. They produce 2000 Lego bricks per shift.
3. Mini-factories and machines for industrial production with a capacity of 750 pieces per hour.

High-quality machines for a small business must withstand up to 500,000 cycles, industrial mini-factories can withstand a working range of 600,000 - 1,000,000 cycles.

The average time for the manufacture of one product is 15-30 seconds. In one cycle, 6-8 units of goods can be produced, which speeds up the payback of equipment. Lego blocks for partitions are formed under a pressure of 2 tons. If they are produced under a pressure of 30 tons, then this material is suitable for laying load-bearing walls.

Material manufacturing technology

The main advantage of producing Lego wall material is that there is no need to fire bricks, which means that there is no need to build a bulky oven and carry out a dangerous firing process. Often on the net you can stumble upon the question of how to make a high-quality Lego block, or requests to describe in detail what is the technology for the production of Lego bricks.

To conduct the technological process for the production of wall material, in addition to machine tools, the following equipment is also used:

• crushers and screening sieves connected in one common unit;
• department for preparing the working mixture, consisting of bunkers for mixing all those ingredients that lego products are made of;
• conveyors and conveyor belts for various purposes;
• pallets and electric cars for packaging and transportation of finished products.

In the production process, shovels, containers for various purposes, brushes, propylene tapes and special clamps are used for packaging the finished material.

Each type of blocks is made using a separate matrix. The material for it is high-quality steel grade 40 HN. This is due to the fact that the matrix, along with its contents, is exposed to high pressure. It, like the mixture, goes through at least 500,000 work cycles. Poor-quality material from such loads quickly fails.
