Concrete columns: the Main kinds and scope
reinforced concrete columns is 1-in of load-bearing structural elements of public, residential and industrial buildings. In General, the column is called design vertical type whose cross section is substantially < to her height. By the way, in Ryazan to acquire such, you can LLC «the Representation of concrete products»: http://predstavitelstvo-gbi.ru/.
the Main purpose of reinforced concrete columns is the creation of support for some structural elements of the building (stairs, concrete floors (slabs and beams), etc.).
the Main indicator, which should have reinforced concrete columns is the ability to withstand high vertical loads (the so-called carrying capacity of structures).
In the colon of W/W can be shelves (cantilevered overhangs), or they may not be. These projections are used for placing horizontal structures, which are used directly when constructing slabs.
Columns are made of:
the- high strength varieties of heavy concrete (M300, M500, M400, M600);
- fittings (relaxed and tense) of steel A-I and A-III (sometimes also used and reinforced steel A-IVC and S);
- reinforcing wire GRP-I and BP-I.
There are 2 main manufacturing technology of reinforced concrete columns:
the- bench;
- flow-aggregate.
Main parameters of reinforced concrete columns
in Order to correctly choose reinforced concrete columns it is necessary to consider the following options:
the- the functional purpose of the object.
- the number of storeys;
- the climate of the region;
- the results of geological and geophysical research.
Basic operational parameters of colums:
the- resistance to high-humidity environments;
- seismic resistance;
- structural bearing capacity;
- frost;
- resistance to aggressive media.
Classification of reinforced concrete columns
profile type reinforced concrete columns are:
the- black;
- round;
- square.
For the production technology of reinforced concrete columns are:
the- solid;
- teams.
At the place of installation of R/C columns are divided into:
the- installed in the intermediate rows;
- established in the extreme series.
- facade products type.
In the form of production of reinforced concrete columns are:
the- two-way;
- unilateral;
- dual console;
- odnokomnatnaya;
- beskonsolnye.
By way of installing reinforced concrete columns are:
the- pillars-columns;
- piles-columns.
area of application reinforced concrete columns are:
the- continuous;
- bottom;
- middle;
- top.
type reinforced concrete columns are divided into:
the- T1;
- S1;
- L1;
- L;
- N;
- SS;
- ;
- So
