Description

Steel column inserts basement variable cross section node

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.

FIG. 2 is a schematic view of the various steel columns;

description of the reference symbols

The steel column comprises an upper steel column 1, a gradual change section steel column 2, a lower steel column 3, a cross steel column 4, a column longitudinal rib 5, a column hoop rib 6, a batten plate 7, a stud 8 and an inner partition plate 9.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in the figure, a steel column inserts basement variable cross section node, from the top down is upper portion steel column 1, gradual change section steel column 2, lower part steel column 3, cross steel column 4, wherein connects through gradual change section steel column 2 between upper portion steel column 1 and the lower part steel column 3, and the 3 sectional areas of lower part steel column are less than upper portion steel column 1, are cross steel column 4 below the lower part steel column 3, and the cross-section of cross steel column 4 is the cross.

The steel column contracts after entering the basement range, and then is converted into the cross steel column 4 to reduce the concrete column section size required by the structure, and the cost can be reduced while the strength is met.

Upper portion steel column 1, gradual change section steel column 2, lower part steel column 3, cross steel column 4 are provided with a plurality of posts outward and indulge muscle 5, and the post is indulged muscle 5 and is set up along the steel column direction, and the post is indulged and is connected through a plurality of post stirrups 6 between the muscle 5, and the post is indulged muscle 5 and post stirrup 6 and all is used for the structural strength between reinforcing bar and the concrete.

A plurality of batten plates 7 are arranged between the flanges of the bottommost cross-shaped steel column 4, and the batten plates 7 are used for guaranteeing the stability of the steel column.

The upper steel column 1, the gradual change section steel column 2, the lower steel column 3 and the cross steel column 4 are all provided with the peg 8 on the surface, and the peg 8 is used for strengthening the overall strength between steel column and the concrete.

And inner partition plates 9 are arranged in the upper steel column 1, the transition section steel column 2 and the lower steel column 3, the inner partition plates 9 all need to be provided with holes, and the holes can ensure that concrete can be poured to the position above the top surface of the concrete beam on the inner side of the square tube/box type steel column.
