After adopting above-mentioned scheme, be used for reducing the required concrete column cross-section size of structure, reduce the occupation space to the building area.
Description
Technical Field
The utility model relates to a building materials field refers in particular to a steel column inserts basement variable cross section node.
Background
At present, the conventional mode of inserting a steel column into a basement is that the steel column is inserted into a uniform cross section and is converted into a profile steel concrete column by wrapping concrete outside the steel column, the thickness of the wrapping concrete is at least 200mm on each side according to 'Combined structural design Specification' JGJ 138 + 2016, and when the steel column is a square tube/box type column, an anchor bolt is arranged on the periphery of the steel column, and sometimes 250mm outside wrapping is needed to meet the structural requirement, so that the cross section of the basement concrete column is enlarged by 400 mm-500 mm compared with the cross section of an upper steel column, while the computational calculation of a non-civil defense basement does not need the large column cross section, and. Therefore, the inventor further researches the variable cross-section node of the basement to develop a steel column, and the variable cross-section node is produced by the variable cross-section node.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a steel column inserts basement variable cross section node for reduce the required concrete column cross-section size of structure, reduce the occupation space to the building area.
In order to achieve the above purpose, the technical solution of the present invention is as follows:
the utility model provides a steel column inserts basement variable cross section node, includes upper portion steel column, lower part steel column, connects through the gradual change section steel column between upper portion steel column and the lower part steel column, and the lower part steel column sectional area is less than upper portion steel column, is the cross steel column below the lower part steel column, and the cross-section of cross steel column is the cross.
The steel column contracts after entering the basement range and then is converted into the cross steel column, so that the size of the section of the concrete column required by construction is reduced, the strength is met, and the cost is reduced.
Further, column longitudinal ribs are arranged outside the upper steel column, the gradual change section steel column, the lower steel column and the cross steel column, and the column longitudinal ribs are connected through column hooping ribs.
The column longitudinal bars and the column stirrups are both used for reinforcing the structural strength between the steel bars and the concrete.
Furthermore, a plurality of batten plates are arranged between the flanges of the cross-shaped steel column.
And the batten plate is used for ensuring the stability of the steel column.
Furthermore, the surfaces of the upper steel column, the gradient section steel column, the lower steel column and the cross-shaped steel column are all provided with studs.
The studs are used to strengthen the cohesion between the steel column and the concrete.
Furthermore, inner partition plates are arranged in the upper steel column, the transition section steel column and the lower steel column, and the inner partition plates are all required to be provided with holes.
The holes can ensure that concrete can be poured on the top surface of the concrete beam on the inner side of the square tube/box type steel column.
After the scheme is adopted, compared with the prior art, the utility model, have following advantage:
the steel column contracts after entering the basement range, then converts the steel column into the cross steel column for reduce the required concrete column cross-section size of structure, compare traditional method security on more reliable, construction convenience and cost's balance also more reasonable.
