Assembly
reinforcement cages of under-columns are produced at the assembly stand with the help of a jig
designs of TsNIIOMTP in the following sequence:
laying reinforcing mesh on
the conductor and fix in the design position with a knitting wire, followed by
electric tack;
remove the armocarnass from the conductor
truck crane and stacked on a platform for storage.
To the place of installation of reinforcement cages
delivered by road.
Fittings are being installed
in sequence:
install reinforcing mesh shoe
on clamps that provide a protective layer of concrete according to the project;
after shoe formwork
install the armoframe of the column with fixing it to the lower grid
knitting wire.
Formwork of monolithic reinforced concrete
foundations are made of separate unified steel formwork blocks.
In the set of formwork block forms for the foundations considered in this
technological map, included, formwork block of the two-stage shoe part
foundation and a sub-column block, consisting of two blocks.
Assembly units of steel formwork
forms and their number are given in table. 5.
Steel formwork for
reinforced concrete monolithic foundations must be delivered to the construction site
Completely in a condition suitable for assembly and operation.
Installation of steel shuttering block forms
produced in the following technological sequence:
install formwork block
of the two-stage shoe part of the foundation to the design position strictly according to the axial risks applied
on concrete preparation, and fix it with metal pins to the base;
mounted on center pins
formwork frame of shoe part of foundation formwork block of under-column and
fix it with clamps;
install scaffolds on centering
install ladder and secure
upper end on the scaffold;
install the inserts on the centering
the pins of the upper block of the column and are fixed with clamps;
Dismantling of the formwork is carried out immediately
after concrete reaches design strength.
Dismantling of block forms is carried out in
following order:
dismantle scaffolding;
dismantle liners;
open lock ties with
devices for opening blocks, take the shutters of the blocks away from the concrete;
detach the sub-column block from the frame
formwork of the shoe part of the foundation;
dismantle the sub-column block;
knock out the wedge, turn the finger and
the shoe shields are removed from the concrete, after which the shoe block form is dismantled
parts of the foundation.
formwork if necessary
the surface is cleaned of adhering concrete with metal brushes and scrapers and
produce lubrication with an emulsion composition.
Dismantled formwork blocks
transported to the place of new concreting.
After verifying the correct installation
formwork and reinforcement make concrete foundations.
Transportation of concrete mix
carried out by a concrete mixer truck with unloading into rotary bins or
receiving funnel of the concrete pump.
Included in the concreting work
foundations include:
receiving and supplying concrete mix;
laying and compaction of concrete mix.
Supply of concrete mix in the structure
provided in two options:
truck crane SMK-10
rotary bunkers;
concrete pump SB-126A (with
mobility of the concrete mixture from 4 to 16 cm).
Foundation concreting
is carried out in two stages: at the first stage, the foundation shoe is concreted and
sub-column to the mark of the bottom of the liner; at the second stage, the upper part is concreted
sub-column after installing the liner.
Concrete mixture is laid
horizontal layers with a thickness of 30 - 40 cm.
Each layer of laid concrete
carefully compacted with a deep vibrator. When compacting the concrete mixture, the end
the working part of the vibrator should be immersed in the previously laid concrete layer on
depth 5 - 10 cm. The vibrator adjustment ball should not exceed 1.5 radius
his actions.
Covering the previous layer of concrete
subsequent must be carried out before the start of concrete setting in the previous
layer.
Concrete formwork in the corners and at the walls
the mixture is additionally compacted by bayoneting with manual metal screws.
Concreting of foundations is carried out with
hanging scaffolds.
When concreting monolithic
foundations with a concrete pump SB-126A, the range of the distribution boom
allows to make laying of concrete mix in one row from two points.
Concrete care measures in
the period of strength development, the procedure and timing of their implementation, control over the implementation
these activities must be carried out in accordance with the requirements of SNiP 3.03.01-87
Load-bearing enclosing building structures. Rules for the production of works.
The terms of aging and the frequency of watering are determined by the construction laboratory.
Limit position deviation
formwork elements, reinforcement and completed monolithic foundations relative to
center axes or reference marks upon acceptance should not exceed the values
specified in SNiP
3.03.01-87.
Technical criteria and means
control operations and processes are given in table. one.
