Description

Technical Field

[0001] This utility model belongs to the field of civil engineering technology, and specifically relates to a cross bracing support device for foundation pit support. Background Technology

[0002] In foundation pit support, steel pipes are often used as cross braces between walers, and the connection between the cross braces and walers is mostly by welding. When the foundation pit walers and cross braces are connected by welding, the installation and removal of the cross braces become cumbersome, seriously affecting the on-site construction progress. Moreover, with the increase in the number of installations and dismantlings, the damage to the cross braces and walers caused by welding and cutting increases, greatly shortening the service life of materials and increasing project costs.

[0003] Therefore, to solve the above problems, it is necessary to provide a cross bracing support device for foundation pit support, so as to simplify the installation and dismantling process of the cross bracing, improve on-site construction efficiency, reduce damage to the cross bracing and walers during the installation and dismantling process, extend the service life of materials, and further save project costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cross brace support device for foundation pit support that is simple in structure, easy to use, and can effectively avoid the problem of cross brace slippage during foundation pit support and improve the stability of foundation pit support.

[0005] The technical solution of this utility model is as follows:

[0006] A cross bracing support device for foundation pit support includes: a lifting hole, a hook, a backing plate, a support plate, and anti-slip plates. The lifting hole is located at the top of the hook. The hook has an L-shaped plate structure. The horizontal end of the hook is fixedly connected to the top of the back of the backing plate. The bottom of the backing plate is vertically fixedly connected to one end of the support plate. Several anti-slip plates are provided between the backing plate and the support plate. The anti-slip plates have a triangular plate structure.

[0007] Furthermore, the diameter of the lifting hole is 10-20mm, the length of the hook is 100-150mm and the width is 30mm; the length of the backrest plate is 250mm and the width is 250mm; the length of the support plate is 250mm and the width is 150mm; the anti-slip plate is a right-angled triangle plate with two right-angled sides of 150mm.

[0008] Furthermore, the distance between the lifting hole and the backrest plate is slightly wider than the thickness of the steel waler.

[0009] The beneficial effects of this utility model are:

[0010] This utility model provides a cross bracing support device for foundation pit support. It has a simple structure, high strength, and convenient installation. It can effectively improve the stability and safety of the cross bracing system. By reasonably setting the lifting holes, L-shaped hooks and support structure, the device can achieve high compatibility and high anti-slip performance with the steel waler, significantly reducing the risk of slippage and support failure during construction. It has good application prospects and promotion value. Attached Figure Description

[0013] In the diagram: 1-Hanging hole, 2-Hook, 3-Backrest plate, 4-Support plate, 5-Anti-slip plate. Detailed Implementation

[0014] like Figure 1-2 As shown, a cross bracing support device for foundation pit support includes: a lifting hole 1, a hook 2, a backing plate 3, a support plate 4, and anti-slip plates 5. The lifting hole 1 is located at the top of the hook 2. The hook 2 is an L-shaped plate structure. The horizontal end of the hook 2 is fixedly connected (welded) to the top of the back of the backing plate 3. The bottom of the backing plate 3 is vertically fixedly connected (welded) to one end of the support plate 4. Several anti-slip plates 5 are provided (welded) between the backing plate 3 and the support plate 4. The anti-slip plates 5 are triangular plate structures.

[0015] Preferably, the diameter of the lifting hole 1 is 10-20mm, the hook 2 is 100-150mm long and 30mm wide, the backrest plate 3 is 250mm long and 250mm wide, the support plate 4 is 250mm long and 150mm wide, and the anti-slip plate 5 is a right-angled triangle with two right-angled sides of 150mm.

[0016] Preferably, the distance between the lifting hole 1 and the backrest plate 3 is slightly wider than the thickness of the steel waler.

[0017] Preferably, the hook 2 is fixedly connected to the backrest plate 3, the backrest plate 3 is fixedly connected to the support plate 4, and the anti-slip plate 5 is fixedly connected to the backrest plate 3 and the support plate 4 by welding. Alternatively, bolts can be used to achieve a detachable structure according to usage requirements.

[0018] Preferably, the hook 2, backrest plate 3, support plate 4 and anti-slip plate 5 can be made of Q235 or Q345 steel, and the surface is hot-dip galvanized or painted to adapt to humid or corrosive construction environments.

[0019] When the foundation pit needs to be installed with cross bracing, the center point of the cross bracing is marked out in advance according to the design drawings. Then, the support device is lifted through the lifting hole 1 using a hoist. With the help of workers, the hook 2 of the support device is suspended on the foundation pit waler, and the support device is adjusted to the center point of the cross bracing to complete the installation of the support device.

[0020] When the cross bracing of the foundation pit is removed, the support device can be lifted to the designated position or the next cross bracing installation position through the lifting hole 1 using a lifting tool.

[0021] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
