Description

Technical Field

[0001] This utility model relates to the field of foundation pit support technology, and particularly to the field of foundation pit support bracket technology, specifically referring to a prefabricated foundation pit support bracket. Background Technology

[0002] An excavation pit is a space excavated downwards from the ground for the construction of the underground portion of a building or structure. Excavation pit support consists of retaining walls, waterproof curtains, walers, supports (anchors), and columns (piles), and is a crucial structure for protecting the underground main structure and the safety of the surrounding environment. Corbels are the supporting structure for the walers, ensuring their stability.

[0003] Prefabricated construction technology is a building construction method. Its main feature is that components are prefabricated in a factory and then transported to the construction site for assembly. This can improve construction efficiency, reduce on-site construction time and labor costs, have a small impact on the environment, and also help improve the controllability and consistency of building (structure) quality, and strengthen the informatization and greening of civil engineering construction.

[0004] Prefabricated foundation pit support consists of retaining walls such as steel sheet piles, horizontal supports, and corbels. The support structure is reliable, reusable, and recyclable. It requires less masonry work, reduces environmental pollution, improves construction efficiency and safety, and has a low overall cost.

[0005] However, due to the different types of foundation pits and varying waler elevations, corbels need to be installed at different elevations, resulting in a low reuse rate of structural components. Furthermore, welding and dismantling corbels is cumbersome, and the welds are vertical, making quality control difficult. If the retaining wall is not made of sheet piles or similar materials that cannot be welded, corbel installation requires pre-embedded connectors in the retaining wall, further complicating the process.

[0006] Therefore, it is desirable to provide a prefabricated foundation pit support bracket that is simple and convenient to install, has a stable structure, can effectively support the waler, and can be reused and recycled, which can reduce environmental pollution, improve construction efficiency and safety, and reduce construction costs.

[0031] The support plate 2 can have any suitable shape, please refer to Figure 2 As shown, in a specific embodiment of this utility model, the support plate 2 is a right-angled trapezoidal plate. The left and right sides of the right-angled trapezoidal plate are both vertically arranged and along the front-back direction, and are spaced apart from each other. The left side of the right-angled trapezoidal plate is located to the right of the bottom of the extrusion plate 1 and is connected to the bottom of the extrusion plate 1. The top surface of the right-angled trapezoidal plate is horizontally arranged and along the left-right direction. The bottom surface of the right-angled trapezoidal plate is arranged along the front-back direction and is inclined to the upper right in the direction from left to right.

[0032] The extrusion plate 1 can have any suitable shape; please refer to [link / reference]. Figure 2 As shown, in a specific embodiment of this utility model, the extrusion plate 1 is a rectangular plate.

[0033] The left and right sides of the extrusion plate 1 can be any suitable side. In a specific embodiment of the present invention, the left and right sides of the extrusion plate 1 are rough surfaces.

[0034] The prefabricated foundation pit support bracket can also include any other suitable components. In a specific embodiment of this utility model, the prefabricated foundation pit support bracket further includes a hook (not shown in the figure). The hook is located on the right side of the extrusion plate 1 and is connected to the extrusion plate 1 and is higher than the support plate 2. The opening of the hook faces downward and is used to hang on the waler 4. When the extrusion plate 1 is a rectangular plate, the hook is located on the right side of the right side of the rectangular plate and is connected to the right side of the rectangular plate.

[0035] The hook is located on the right side of the extrusion plate 1 and connects to the extrusion plate 1. It can be located on the right side of any suitable position on the extrusion plate 1 and connect to any suitable position on the extrusion plate 1. In one specific embodiment of this utility model, the hook is located on the right side of the top of the extrusion plate 1 and connects to the top of the extrusion plate 1. When the extrusion plate 1 is a rectangular plate, the hook is located on the right side of the top of the right side of the rectangular plate and connects to the top of the right side of the rectangular plate.

[0036] The hook can have any suitable shape. In one specific embodiment of this utility model, the hook is an inverted L-shaped hook, which includes a horizontal bar and a vertical bar. The left end of the horizontal bar is located on the right side of the extrusion plate 1 and connected to the extrusion plate 1, and the right end of the horizontal bar is connected to the upper end of the vertical bar. When the extrusion plate 1 is a rectangular plate, the left end of the horizontal bar is located on the right side of the right side of the rectangular plate and connected to the right side of the rectangular plate.

[0037] The number of hooks can be determined as needed. Preferably, there are multiple hooks, which are spaced apart from each other. "Multiple" here refers to two or more hooks. In one specific embodiment of this utility model, the number of hooks is two.

[0038] In use, taking the retaining wall 3 (e.g., steel sheet piles) as an example, which is set vertically and along the front-to-back direction, and the waler 4 as a example, which is set along the front-to-back direction and located on the right side of the retaining wall 3, the support plate 2 is placed under the waler 4 and against the waler 4, and the pressing plate 1 is placed between the retaining wall 3 and the waler 4. When the retaining wall 3 and the waler 4 are pressed together, the pressing plate 1 will be pressed between the retaining wall 3 and the waler 4. The greater the pressure, the more firmly the pressing plate 1 is fixed in the vertical direction by friction.

[0039] With the hook in place, the extrusion plate 1 can also be hung on the waler 4 via the hook (the waler 4 can be inserted between the hook and the support plate 2 in the front-to-back direction). If the waler 4 is an H-beam waler, the hook can be hung on the flange plate of the H-beam waler.

[0040] The mechanism by which the corbel of this invention functions is as follows: After the foundation pit support structure is installed, the lateral pressure of the soil outside the pit acts on the retaining wall 3. The retaining wall 3 transmits the force to the waler 4 through the compression plate 1. The waler 4 is tightened by the support (anchor rod), so the compression plate 1 experiences positive pressure on both sides. The weight of the waler 4 acts on the support plate 2, and the support plate 2 transmits the force to the compression plate 1. Therefore, the compression plate 1 experiences a downward force, which balances the upward frictional force. The greater the lateral pressure of the soil, the more stable this balance system is, and it can effectively support the waler 4.

[0041] This utility model has a reliable structure, can be reused and recycled, and its prefabricated structure can reduce environmental pollution, improve construction efficiency and safety, and has a low overall cost.

[0042] In summary, the prefabricated foundation pit support bracket of this utility model is simple and convenient to install, has a stable structure, can effectively support the waler, and can be reused and recycled, which can reduce environmental pollution, improve construction efficiency and safety, reduce construction costs, and is ingeniously designed, simple in structure, easy to manufacture, and low in manufacturing cost, making it suitable for large-scale promotion and application.

[0043] Therefore, it is evident that the objective of this utility model has been fully and effectively achieved. The function and structural principles of this utility model have been demonstrated and explained in the embodiments. Without departing from the stated principles, any modifications can be made to the implementation methods. Therefore, this utility model includes all modified embodiments based on the spirit and scope of the claims.
