Technical Field

[0001] This application relates to the field of building structure technology, and in particular to a foundation pit reinforcement structure for building construction. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plane dimensions, used for the initial pouring of the building structure foundation. In order to prevent rainwater from seeping into the soil and causing the walls at the bottom of the excavation pit to collapse, the walls at the bottom of the excavation pit need to be fixed and supported by a support and reinforcement structure after the excavation is completed.

[0003] Currently, some foundation pit support structures mainly rely on steel inclined support beams to support the inner wall of the foundation pit. This support method is not very strong, so there is still room for improvement. Utility Model Content

[0004] In order to improve the support strength of the inner wall of the foundation pit, this application provides a foundation pit reinforcement structure for building construction.

[0005] This application provides a foundation pit reinforcement structure for building construction, which adopts the following technical solution:

[0006] A foundation pit reinforcement structure for building construction includes a support plate supported on the side wall of the foundation pit and a plurality of reinforcement plates abutting against the support plate. A support structure is provided between adjacent reinforcement plates. The support structure includes a connecting part and an abutting plate. The connecting part includes a connecting rod and a positioning rod. The connecting rod extends and connects between the opposite reinforcement plates. The positioning rod is inserted into the connecting rod and positioned at the bottom of the foundation pit. The abutting plate is installed on the positioning rod and abuts against and supports the support plate.

[0007] By adopting the above technical solution, the support plate is supported on the side wall of the foundation pit under the abutment action of the reinforcement plate. The connecting rod is set between adjacent reinforcement plates to improve the structural stability of adjacent reinforcement plates. Furthermore, the positioning rod of the positioning connecting rod and the abutment plate installed on the positioning rod are set to increase the support area of ​​the foundation pit side wall and improve the support stability of the foundation pit side wall.

[0008] Preferably, the connecting part further includes an extension sleeve, with the opposite ends of the connecting rod and the extension sleeve respectively threaded to the corresponding adjacent reinforcing plates, and the connecting rod inserted into the extension sleeve. Corresponding through positioning grooves are provided on the connecting rod and the extension sleeve at intervals, and the positioning rod is inserted into the positioning groove.

[0009] By adopting the above technical solution, the distance between adjacent reinforcing plates can be adjusted by inserting the connecting rod and the extension sleeve, which is convenient to adjust according to the support requirements of the pit sidewall. The positioning rod plays a positioning role for the adjusted connecting rod and extension sleeve.

[0010] Preferably, the abutment plate is installed on the positioning rod by a fixing structure; the fixing structure includes fixing plates extending from the two end walls of the abutment plate, and a fixing groove for the fixing plates to be engaged is provided on the reinforcing plate; a support block extending from the side wall of the abutment plate abuts against the support plate.

[0011] By adopting the above technical solution, the fixing plate is snapped into the fixing groove to achieve longitudinal positioning of the abutment plate, so that the abutment plate is stably fixed at the middle position of the positioning rod, which plays a supporting role on the pit sidewall at the gap between the opposite reinforcement plates, thereby improving the structural stability of the reinforcement plate and the supporting effect on the pit sidewall.

[0012] Preferably, the fixing structure further includes a deformable fixing ring with an opening fixed to the side wall of the abutment plate, and the fixing ring can be fitted onto the positioning rod.

[0013] By adopting the above technical solution, the positioning rod provides the positioning point of the abutment plate, and the deformable fixing ring with an opening can complete the process of setting the ring in place on the positioning rod through the deformation space provided by the opening, thereby improving the installation stability of the abutment plate.

[0014] Preferably, the fixing ring is made of rubber, and a rubber collar is fixed on the positioning rod at the location corresponding to the fixing ring.

[0015] By adopting the above technical solution, the rubber fixing ring and the rubber sleeve can be matched to improve the contact friction, so that the fixing ring is stably positioned on the positioning rod and is not easy to slip.

[0016] Preferably, the reinforcing plate is fixed to the support plate by an installation structure, and the reinforcing plate is fixed to the bottom of the pit by bolts.

[0017] Preferably, the installation structure includes an inclined extrusion column and an extrusion groove. The extrusion column is deformable and fixed to the side wall of the reinforcing plate, and the extrusion column extends obliquely upward toward the support plate. The extrusion groove is opened through the support plate and extends obliquely in the same direction as the extrusion column. The extrusion column is interference-fitted into the corresponding position of the extrusion groove.

[0018] By adopting the above technical solution, the installation stability of the reinforcing plate is improved by utilizing the combination of deformable extrusion columns and extrusion grooves, and the inclined extrusion grooves can avoid dust accumulation.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] The support plate is supported on the side wall of the pit by the abutment action of the reinforcement plate. The connecting rod is set between adjacent reinforcement plates to improve the structural stability of adjacent reinforcement plates. Furthermore, the positioning rod of the positioning connecting rod and the abutment plate installed on the positioning rod are set to increase the support area of ​​the pit side wall and improve the support stability of the pit side wall.

[0021] The distance between adjacent reinforcing plates can be adjusted by inserting the connecting rod and the extension sleeve. The positioning rod positions the adjusted connecting rod and the extension sleeve. The positioning rod provides the positioning point for the abutment plate. The deformable fixing ring with an opening can further deform through the opening to complete the process of setting the ring in place on the positioning rod, thereby improving the installation stability of the abutment plate.

[0022] The fixing plate is snapped into the fixing groove to achieve longitudinal positioning of the abutment plate, so that the abutment plate is stably fixed at the middle position of the positioning rod, which supports the pit sidewall at the gap between the opposite reinforcement plates, improving the structural stability of the reinforcement plate and the supporting effect on the pit sidewall.

[0023] The combination of deformable extrusion columns and extrusion grooves improves the stability of the reinforcing plate's support for the support plate, while the inclined extrusion grooves prevent dust accumulation. Attached Figure Description
