Abstract
Description
Technical Field
[0001] This utility model relates to the field of building foundation pit support technology, and in particular to a temporary fixing tool for foundation pit support diagonal bracing. Background Technology
[0002] Inclined bracing is a commonly used method for foundation pit support. Its principle involves connecting the foundation pit retaining structure to the central island floor using a combination of bored piles or SMW (Surface Mount Welded) piles and inclined steel pipe bracing, forming a unified structure to withstand the horizontal and vertical loads during excavation. The inclined bracing effectively reduces deformation and displacement of the foundation pit retaining structure, ensuring the stability and safety of the foundation pit.
[0003] The existing inclined bracing is installed during the foundation pit excavation process. Before the soil at the bottom of the bracing is excavated, the support piles have not shifted into the foundation pit, the inclined bracing is not in contact with the concrete corbel, and the inclined bracing is not subjected to axial support force. Therefore, the bracing cannot form a tight contact with the concrete corbel to generate internal friction. At this time, a U-shaped hanger is needed to temporarily fix the inclined bracing to the concrete corbel. After the soil excavation, the bracing is subjected to axial force, and the component is removed from the work.
[0004] Currently, temporary fixing U-shaped components are mostly connected to the inclined bracing by on-site welding. This method has the following problems:
[0005] (1) On-site welding is prone to positioning deviation.
[0006] (2) Welding quality cannot be guaranteed.
[0007] (3) The installation speed is slow and cannot meet the needs of rapid construction. Utility Model Content
[0008] The purpose of this utility model is to provide a temporary fixing tool for foundation pit support diagonal bracing, which solves the technical problems of slow installation speed and inability to guarantee quality of fixing components in the prior art.
[0009] This application discloses a temporary fixing tool for diagonal bracing in foundation pit support, comprising:
[0010] Liang Tuo;
[0011] The inclined brace has a liner end that mates with the beam support;
[0012] An auxiliary component is provided at one end on the inclined brace and at the other end on the beam support;
[0013] The auxiliary components include:
[0014] A fixed hanging plate is attached to the end of the liner plate of the inclined brace at one end and suspended from the inclined brace at the other end.
[0015] The fixing plate is a one-piece molded part, and the fixing plate includes:
[0016] Horizontal section;
[0017] An inclined segment is connected to the end of the horizontal segment, and the angle formed between the inclined segment and the horizontal segment is α;
[0018] The acute angle of the beam support is β, and α = β.
[0019] This application simplifies the assembly structure and improves work efficiency by using a fixed hanging plate for suspension.
[0020] Based on the above technical solution, the embodiments of this application can be further improved as follows:
[0021] Furthermore, the auxiliary component also includes:
[0022] Two limiting plates are installed at intervals on both sides of the inclined section;
[0023] Two connecting plates are installed at intervals on the end of the liner of the inclined brace. The inclined section of the fixed hanging plate is located between the two limiting plates. The bottom of the limiting plate and the top of the connecting plate are in contact and cooperate. The beneficial effect of this step is that the limiting plate and the connecting plate cooperate with each other to ensure the stability of the connection between the auxiliary component and the inclined brace, thereby ensuring the stability of the entire auxiliary component during use.
[0024] Furthermore, the top of the connecting plate is convex, and the bottom of the limiting plate is grooved. The beneficial effect of this step is to further ensure the stability of the auxiliary component assembly.
[0025] Furthermore, the bottom of the limiting plate and the top of the connecting plate are both inverted "V" shapes.
[0026] Furthermore, the limiting plate and the inclined section are connected by fixing bolts. The advantage of this step is that it enables the stable assembly of the auxiliary components.
[0027] Furthermore, the beam support is a concrete corbel.
[0028] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0029] 1. The components in this application can be pre-welded and assembled on-site to form a workpiece, which can ensure the quality of the workpiece.
[0030] 2. This application uses two limiting plates to restrict the position, so as to facilitate the stable assembly of the fixed mounting plate.
[0031] 3. This application designs the ends of the connecting plate and the limiting plate so that the ends of the two are mated, which can ensure that the auxiliary parts are stably installed to the ends of the inclined brace, thereby ensuring the stability of the structure.

[0043] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.
[0044] Example 1:
[0045] like Figure 1-3 As shown in the figure, this application discloses a temporary fixing tool for foundation pit support diagonal bracing, which is used to assist diagonal bracing in achieving foundation pit support. It can be assembled on site, has a simple structure, is easy to operate, and is easy to assemble and disassemble.
[0046] like Figure 1 As shown, the specific structure in this application includes:
[0047] Beam support 1, which is an existing structure, specifically a concrete corbel, serves as a connecting and supporting element;
[0048] The inclined brace 2 has a liner end that mates with the beam support 1. The inclined brace 2 includes components such as a liner, which is specifically located at the end of the inclined brace 2 and is used to connect with other components.
[0049] Auxiliary component 3, one end of which is set on the inclined brace 2 and the other end of which is set on the beam support 1, serves as an auxiliary support, specifically by providing a stable connection between the corresponding inclined brace and the beam support (bracket).
[0050] The auxiliary component 3 includes:
[0051] The fixed hanging plate 301 is fixed at one end to the liner end of the inclined brace 2 and suspended at the other end on the inclined brace 2. The fixed hanging plate 301 in this application mainly serves as a suspension function, which can assist the connection between the inclined brace 2 and the beam support, thereby further ensuring the stability of the connection between the two.
[0052] In one embodiment, to improve the ease of installation of this application, the fixing plate 301 in this application is an integrally formed part, which is beneficial to the assembly of the inclined brace.
[0053] Among them, such as Figure 2 , 3 As shown, the fixed mounting plate 301 includes:
[0054] The horizontal section 302 is located on the upper surface of the beam support 1 during subsequent assembly, thereby ensuring the stability of the hanging plate during installation.
[0055] An inclined segment 303 is connected to the end of the horizontal segment 302, and the angle formed between the inclined segment 303 and the horizontal segment 302 is α.
[0056] The acute angle of the beam support 1 is β, and α=β. By designing the angle, a stable assembly between the fixed hanging plate 301 and the beam support 1 can be achieved.

[0063] The installation process of this application will be further explained as follows:
[0064] S1: Determine the welding position of the limiting plate 304 on the liner plate of the inclined brace 2, and perform positioning and layout;
[0065] S2: Weld the lining plates of the limiting plate 304 and the inclined brace 2;
