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

Embodiment 1
[0014] Such as figure 1 , figure 2 , image 3 The connecting piece shown includes H-shaped steel 3, and a plurality of connecting holes 6 are opened on both sides of the H-shaped steel 3. The four connecting holes 6 form a group, and the four connecting holes 6 in each group are distributed in a square shape with four corners. The two ends of the H-shaped steel 3 are cross-sections and are welded and fixed with a rectangular sealing plate 1. The grooves on both sides of the H-shaped steel 3 are respectively provided with a plurality of reinforcing ribs 4, and the reinforcing ribs 4 are located in the same group. In the middle of the two adjacent connection holes 6, the reinforcing ribs 4 are perpendicular to the web and side flanges of the H-shaped steel 3 and fixed by welding, and the two reinforcing ribs 4 near the two ends of the H-shaped steel 3 are provided with hanging holes 2. At least one drainage hole 5 is opened on the web of the H-shaped steel 3 between two adjac...

Abstract
The invention discloses a connecting piece. The connecting piece comprises H-shaped steel; a plurality of connecting holes are formed in two side wing plates of the H-shaped steel; four connecting holes are in a group; the four connecting holes in every group are formed in four corners of a quadrate; two end surfaces of the H-shaped steel are cross sections and rectangular-shaped sealing plates are fixed at the two end surfaces of the H-shaped steel in a welding mode; a plurality of reinforced ribbed plates are arranged inside two side grooves of the H-shaped steel; the reinforced ribbed plates are arranged in a middle position of two right-and-left adjacent connecting holes which are in the same group; the reinforced ribbed plates are perpendicular to web plates and the two side wing plates of the H-shaped steel; the reinforced ribbed plates, the web plates and the two side wing plates are fixed in a welding mode; the two reinforced ribbed plates, which are close to two ends of the H-shaped steel, are provided with hanging holes; the web plate of the H-shaped steel, which is arranged between two adjacent reinforced ribbed plates, is provided with at least a draining hole. According to the technical scheme, the connecting piece is convenient to hoist and assemble and can be reused.
Description
technical field [0001] The invention relates to a high-rigidity integrated prestressed assembled foundation pit support internal support system, in particular to a connecting piece. 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 or steel pipe, and it cannot work as a composite structure, so their support stiffness is relative...
