Comments:
1.Columns are made of heavy concrete of class B45 according to
GOST 26633-85, frost resistance grades
F150, waterproofness W6.
2.Columns are reinforced with spatial knitted frames.
In all columns, embedded
parts are provided for fastening trusses and sub-trusses, embedded
parts for fastening vertical ties are provided in the tie columns, PEIKKO type shoes are installed in the support section of the column
HPKM for connection to the foundation, in the extreme columns there are embedded parts for fixing
the basement panels.
3.Chamfers of 15x15mm should be filled at all corners of columns, including column consoles
.
4.The columns are tested for the forces acting during manufacture,
storage, transportation and
installation, as pivotally supported beams with cantilevers loaded
with a uniformly distributed load from
the column's own weight (reliability coefficient 1.1), taking into account the dynamic coefficient Cd = 1.4.
5.Sling loops are used for strapping columns from the mold and transportation
. It is allowed to replace
the design of slinging devices. It is not allowed to shift the loops from the design face of the column to
others! If it is necessary to change the distance between the loops
from the condition of limiting the length of the traverse,
coordination with the customer is required.
6.For the alignment of columns during installation on the side faces, there are risks of coordination axes at the level
of the top and bottom of the column.
7. The design position of reinforcement products in the formwork should be provided with fixators made of dense
cement-sand mortar or plastic.
8. The position of embedded products for fastening rafter, sub-rafter structures and crossbars, as
well as shoes should be fixed by attaching to the form.
The position of the remaining embedded products
is allowed to be fixed by attaching them to the mold or to the reinforcement frame. The recesses in the base
of the columns for PEIKKO bolts must be carried out according to the company's requirements
PEIKKO with the use of proprietary
infental void-formers or similar void-formers providing the necessary
dimensions and quality of recesses.
9.The opening of the surface of the embedded parts must be protected from corrosion (the recommended
protection scheme is to cover with zinc-containing paint "Cynol" in one layer).
The color of the protective coating should be
close to the color of concrete.
10. The columns should be removed from the mold using a traverse
after the concrete reaches at least 70%
of the design strength in summer and at least 85% in winter. The manufacturer is obliged to guarantee
that the concrete reaches the design strength.
11. The exposed surfaces of embedded products must be cleaned from the influx.
12.The manufacturing accuracy, appearance and quality
of the column surfaces must meet the requirements
GOST 25628-90. Category of concrete surface according to
GOST 13015-2012 is not lower than A2.
Filling of the upper part when concreting the surface of the column is not
recommended. Dimensional accuracy class
in accordance with GOST 21779-82: linear - 4, straightness -
2. Tolerance in plan between shoes
PEIKKO ±2mm. Before mass production of columns, it is necessary
to make a standard of the column and draw
up a certificate of acceptance of the standard by the customer. The deviation of embedded parts in
the support sections (consoles, heads) from
the horizontal is not more than 1 mm!
13.The fire resistance limit of columns is R90.
14.Transportation and storage of columns should be carried out in
a horizontal position in
accordance with the requirements of GOST 13015-2012.
15.The joint of the longitudinal reinforcement should be performed by welding. The type
of welded joint should be accepted according to GOST
14098-2014 of the following: C1-Co, C14-Mp, C15-Rs, C17-Mp,
C19-Rm.
16. All columns must arrive at the construction site
fully ready for installation having gained the necessary strength.
17. Attach a schedule of work to the contract.
1. Work should be carried out in accordance with the requirements of the regulations
(SP, SNiP, GOST, PUE 7, POTEE, etc.) in force on
the territory of the Russian Federation, working documentation and this Technical
Specification;
2. Any changes in the composition and content of the work, the
