Problems solved by technology

The disadvantage is that the rigidity of a single support is not large enough, and its integrity is not as good as that of reinforced concrete supports.
[0005] Due to the cylindrical shape of the steel pipe support, it is difficult to overlap adjacent steel pipes, and it is not easy to achieve a stable joint form; if the outer diameter of the steel pipe is increased to increase the cross-sectional area to improve the support stiffness, it will be due to the increase in the weight of the standard section. Increased difficulty in hoisting
H-shaped steel support is limited by the small cross-

Abstract

The invention discloses a special-shaped flange and a foundation pit steel supporting structure using the same. The special-shaped flange comprises an end plate, a left limiting part connected to the edge of the left side of the end plate, a right limiting part connected to the edge of the right side of the end plate, an upper limiting part connected between the left limiting part and the right limiting part and positioned at the upper part of the end plate, and a lower limiting part connected between the left limiting part and the right limiting part and positioned at the lower part of the end plate, wherein a limiting cavity defined by the components is used for being connected with profile steel in a sleeved mode. The special-shaped flange is connected with the rectangular section steel of the corresponding specification in a sleeved mode, and a closed reinforced box type supporting beam can be formed; according to the structure, the torsional strength of the steel support can be improved, deformation of the support in practical application is effectively prevented, and the corrosion resistance of the steel structure can be remarkably improved through the closed structure.

Description

technical field [0001] The invention relates to the technical field of foundation pit support, in particular to a special-shaped flange and a foundation pit steel support structure using the special-shaped flange. Background technique [0002] At present, there are mainly two types of support systems in deep foundation pits in China: reinforced concrete support and steel support. [0003] Among them, the reinforced concrete support is to bind the steel bars to form a skeleton, and formwork is filled with concrete to form an integral support system with crown beams or purlins. Its advantages are high rigidity and relatively simple construction method. Its shortcomings are also more prominent, mainly in the long molding time, unable to quickly play a supporting role; time-consuming and labor-intensive dismantling, serious vibration, noise, and dust pollution; materials cannot be reused, which does not conform to the concept of green and environmental protection of modern buil...
