Angle brace bracket

Abstract

The invention discloses an angle brace bracket, which comprises an isosceles right triangle reinforcing plate, a first waist side plate, a second waist side plate, and a bottom side plate, wherein a barrel-shaped structure with the cross section of an isosceles right triangle is surrounded by the first waist side plate, the second waist side plate, and the bottom side plate; three sides of the isosceles right triangle reinforcing plate are fixed with the first waist side plate, the second waist side plate, and the bottom side plate respectively in a welding manner; 8 connection holes A with the diameter of 20 mm are formed in the bottom side plate, the vertical adjacent interval is 200 mm, and the horizontal adjacent interval is 100 mm; four connection holes B with the diameter of 28 mm are formed in the second waist side plate, and the vertical and horizontal adjacent interval is 200 mm; a drain hole is formed in the center of the isosceles right triangle reinforcing plate. The isosceles right triangle reinforcing plate is the thick steel plate with the thickness of 10 mm; the first waist side plate, the second waist side plate, and the bottom side plate are all thick steel plates with the thickness of 16 mm. The angle brace bracket adopting the technical scheme can be used in combination and assembly with other support components, is firm and stable in support, and can be used repeatedly.

Description

technical field [0001] The invention relates to a high-rigidity overall prestressed assembled foundation pit support inner support system, in particular to a corner brace bracket used for a high-rigidity integral prestressed assembled foundation pit support inner support system. Background technique [0002] In soft soil deep foundation pit engineering, reinforced concrete or steel pipe supports the support structure. In order to reduce the deformation of the foundation pit and increase the stability, the commonly used methods are: increase the size of the reinforced concrete purlin street surface, increase the number of steel pipe supports, Reduce spacing etc. But this will greatly increase the consumption of building materials and also reduce the effective construction space in the foundation pit. Since the steel support structure currently used mainly uses a single section steel or steel pipe as a support beam, there is no effective connection between each section steel ...

AI Technical Summary

Problems solved by technology

Since the steel support structure currently used mainly uses a single section steel or steel pipe as a support beam, there is no effective connection between each section steel or steel pipe, and it cannot work as a composite structure, so their support stiffness is relatively low. The force it can withstand is relatively limited. For foundation pits with large spans, it is difficult to control their deformation with the current steel support support

Because many of these supports are made according to the requirements of on-site construction, there is no standardized connection size, and the purpose of interchangeability and universal use between various parts cannot be achieved. After the foundation pit construction is completed, most of the support parts have become disposable consumables. , cannot be reused
