Description

Technical Field

[0001] The utility model belongs to the technical field of foundation pit support, and specifically relates to a building foundation pit support component. Background Technique

[0002] Support is a retaining, reinforcement and protection measure for the side wall and surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit. As a structural system, the foundation pit support should meet the requirements of stability and deformation, that is, the requirements of two limit states usually specified in the specifications, namely the ultimate limit state of bearing capacity and the serviceability limit state. The so-called ultimate limit state of bearing capacity means that the support structure is damaged, toppled, slid or the surrounding environment is damaged, resulting in instability in a relatively large range. Generally, the design requirement is that it is not allowed for the support structure to reach this limit state.

[0003] For example, a building foundation pit support component with the publication number CN215367313U includes a retaining frame. Two support mechanisms are installed at the lower part of one side of the retaining frame. Connecting frames are installed at the tops of the two support mechanisms. Rotating rods are rotatably connected between the two sides of the inner cavities of the two connecting frames. Rotating blocks are rotatably connected to the surfaces of the two rotating rods. Support columns are installed on the surfaces of the two rotating blocks. This building foundation pit support component is easy to install, has a stable stress system, is safe and reliable, can ensure the safety of construction workers, has a good support effect, greatly improves the practicability of the whole device, and is suitable for development and popularization;

[0004] This support component is an integral structure and is not adjustable for different foundation pits. At the same time, when two or more support components are used in combination, no connection structure is provided, resulting in a low application range. To solve the above problems, a building foundation pit support component is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a building foundation pit support component to solve the above problems, including:

[0006] Type A baffle, convex plates are welded to both ends of the outer wall of the front side thereof;

[0007] Type B baffle, hook plates are welded to both sides of the outer wall of the front side thereof. Connecting seats are fixedly installed on the outer walls of the front sides of the Type A baffle and the Type B baffle through bolts. I-beams are fixedly installed on the upper surfaces of the multiple connecting seats through bolts. Multiple support mechanisms are fixedly installed on the outer wall of one side of the I-beam through bolts.

[0008] Through the above technical solution, when using the support component, first combine the A-type baffle and the B-type baffle adjacent to each other in pairs. Connect the two baffles with different structures by inserting the concave plate into the hook plate. Place the combined baffle into the foundation pit. Support the foundation pit wall with the baffle. After the baffle is installed, fix the I-beam on the upper surface of the connecting seat in front of the baffle through bolts. Finally, fix the support mechanism inside the I-beams on both sides of the foundation pit through bolts, so as to realize the support of the foundation pit. The baffles can be combined with each other for easy disassembly and carrying.

[0009] In a preferred embodiment, the A-type baffles and the B-type baffles are arranged adjacent to each other in pairs.

[0010] In a preferred embodiment, a groove is provided at the rear side of the A-type baffle.

[0011] Through the above technical solution, since a groove is provided at the rear side of the A-type baffle, more soil enters the rear side of the A-type baffle, resulting in a greater pressure on the rear side of the A-type baffle. At this time, the A-type baffle will drive the convex plate to squeeze the hook plate. This structure can make the connection between the A-type baffle and the B-type baffle tighter, preventing the single baffle from falling and reducing the support effect.

[0012] In a preferred embodiment, reinforcing ribs are welded to both ends of the connecting seat.

[0013] Through the above technical solution, the mechanical strength of the connecting seat is improved by setting the reinforcing ribs.

[0014] In a preferred embodiment, a plurality of threaded holes adapted to the support mechanism are provided on the outer wall of the front side of the I-beam.

[0015] In a preferred embodiment, the support mechanism further includes a fixed rod. One side of the fixed rod is slidably connected with an adjusting rod. Connecting flanges are fixedly installed at the ends of the fixed rod and the adjusting rod.

[0016] Through the above technical solution, for foundation pits with different areas, the length of the support mechanism can be changed by pulling the adjusting rod, so that the support component can be applied to foundation pits with different areas.

[0017] In a preferred embodiment, a locking pin is threadedly connected to the outer wall of one end of the fixed rod.

[0018] Through the above technical solution, after the position of the fixed rod is moved, the position of the fixed rod is fixed by the locking pin.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effect of the present utility model is: The present utility model provides a building foundation pit support component.

[0020] 1. When using the support component, first combine the A-type baffle and the B-type baffle adjacent to each other in pairs. Connect the two baffles with different structures by inserting the concave plate into the hook plate. Place the combined baffle into the foundation pit, and support the foundation pit wall with the baffle. After the baffle is installed, fix the I-beam on the upper surface of the connecting seat on the front side of the baffle through bolts. Finally, fix the support mechanism inside the I-beams on both sides of the foundation pit through bolts, so as to realize the support of the foundation pit. The baffles can be combined with each other for easy disassembly and carrying.

[0021] 2. A groove is provided on the rear side of the A-type baffle, so that more soil enters the rear side of the A-type baffle, resulting in greater pressure on the rear side of the A-type baffle. At this time, the A-type baffle will drive the convex plate to squeeze the hook plate. This structure can make the connection between the A-type baffle and the B-type baffle tighter, preventing the single baffle from falling and reducing the support effect.

[0032] Type A baffle 1, with convex plates 3 welded to both ends of the outer wall on the front side. There is a groove 8 on the rear side of the Type A baffle 1. Since there is a groove 8 on the rear side of the Type A baffle 1, more soil enters the rear side of the Type A baffle 8, resulting in a greater pressure on the rear side of the Type A baffle 1. At this time, the Type A baffle 1 will drive the convex plate 3 to squeeze the hook plate 4. This structure can make the connection between the Type A baffle 1 and the Type B baffle 2 tighter, preventing the single baffle from falling and reducing the support effect;

[0033] Type B baffle 2, with hook plates 4 welded to both sides of the outer wall on the front side. The Type A baffle 1 and the Type B baffle 2 are arranged adjacent to each other in pairs.

Both the front outer walls of the Type A baffle 1 and the Type B baffle 2 are fixedly installed with connecting seats 5 by bolts. Reinforcing ribs are welded to both ends of the connecting seat 5. By setting the reinforcing ribs, the mechanical strength of the connecting seat 5 is improved. On the upper surfaces of multiple connecting seats 5, I-beams 6 are fixedly installed by bolts. On one outer wall of the I-beam 6, multiple support mechanisms 7 are fixedly installed by bolts. Threaded holes adapted to the support mechanisms 7 are provided on the front outer wall of the I-beam 6. After placing the combined baffles into the foundation pit, the foundation pit wall is supported by the baffles. After the baffles are installed, the I-beam 6 is fixedly installed on the upper surface of the connecting seat 5 in front of the baffle by bolts. Finally, the support mechanisms 7 are fixedly installed inside the I-beams 6 on both sides of the foundation pit by bolts, thereby realizing the support of the foundation pit. The baffles can be combined with each other for easy disassembly and carrying;

[0034] The support mechanism 7 further includes a fixed rod 9. A regulating rod 10 is slidably connected to one side of the fixed rod 9. Connecting flanges are fixedly installed at the ends of the fixed rod 9 and the regulating rod 10. For foundation pits of different areas, the length of the support mechanism 7 can be changed by pulling the regulating rod 10, so that the support component can be applicable to foundation pits of different areas. One end outer wall of the fixed rod 9 is threadedly connected with a locking pin 11. After the position of the fixed rod 9 is moved, the position of the fixed rod 9 is fixed by the locking pin 11.
