Problems solved by technology

[0004] Although it can protect the slope of the foundation pit and avoid collapse, in actual use, the construction personnel will continue to dig in the foundation pit, and then the ground of the foundation pit on which the support structure on the upper side originally relied will move down and support The structure needs to be reconfigured, and there is still a risk of collapse when resetting, and the force-bearing mechanism of the existing support structure relies on the support rods in the foundation pit to provide support. construction

Embodiment 1

[0045] Example 1, please refer to Figure 1-3 with Image 6 This embodiment provides a technical solution: a construction foundation pit support structure, including:

[0046] The support plate 1 is provided with four and disposed in the inner wall of the foundation pit, and the top of the support plate 1 is provided with a pit belt protective plate 8 perpendicular to the support plate 1;

[0047] The fixing unit 2 is mounted on one side away from the support plate 1;

[0048] The fixing unit includes an anchoring assembly and a reinforcing assembly that is attached to the side of the pit belt protection plate 8 away from the support plate 1, and a reinforcing assembly is mounted on the anchor assembly. By the anchoring assembly is convenient to the surface of the pit belt protective plate 8 above the foundation pit, the anchoring effect of the anchoring assembly can be increased by the reinforcing assembly, and the anchoring assembly is removed or displaced in the soil layer.

Embodiment 2

[0061] Example 2, please refer to Figure 1-3This embodiment provides a technical solution: a building foundation pit support structure, which is substantially the same as the embodiment of the embodiment, and the difference is that the connection assembly and the pressing assembly are different.

[0062] The connection assembly includes a connecting rod 1 51, a bearing one 52, a connecting bolt 53, a connection nut 54, and a connecting rod 2 55, and the bottom side surface of the support plate 1 fixes a connecting rod 1 51, the end of the connecting rod 1 52 through the bearing one 52 Turning the top of the connection bolt 53, the top side side of the plug-9 is fixed to the position of the connecting rod 1 51, and the end of the connecting rod 2 55 is fixed to the connection nut 54 corresponding to the connection bolt 53, The connection nut 54 is threaded with the bottom end of the connection bolt 53. By rotating the connection bolt 53, the connection bolt 53 can be threaded with ...

Embodiment 3

[0064] Example 3, please refer to figure 1 In this embodiment, the present embodiment provides a technical solution: a construction foundation pit support structure, which is substantially the same as the above embodiment, and the distinction is: further including the central support opening unit 4, the central support open unit 4 includes support The mounting block 41 is opened, and the drum 42, the supporting rod 43, the block 44, the casing 45, the side surface of the support plate 1 are fixed, and the movable vertical shaft active vertical axis movable connection support on the mounting block 41 is opened. The drum 42 is opened, and the side connection of the side of the drum 42 is opened, and the other end of the opening rod 43 is connected to the block 44, the adjacent other support plate 1 is adjacent to the position equal to the position of the mounting block 41. The card holder 45 is provided, and the block 44 of the head portion of the opening rod 43 is attached to the c...

Abstract

The invention provides a building foundation pit supporting structure. The building foundation pit supporting structure comprises four supporting plates, fixing units, top opening units, mounting units and corner angle supporting units, wherein the four supporting plates are arranged on the inner wall of a foundation pit to define a supporting frame, and pit edge protection plates perpendicular to the supporting plates are arranged on the tops of the supporting plates; the fixing units are installed on the sides, away from the supporting plates, of the pit edge protection plates; the adjacent pit edge protection plates are connected through the top opening units; the bottoms of the supporting plates are connected with a mounting plate through the mounting units; and the adjacent supporting plates are connected through the corner angle supporting units. During downward excavation construction in the foundation pit, the mounting plate for supporting can be additionally arranged downwards on the basis that an original supporting structure is not disassembled, a supporting mechanism does not need to be arranged again, the risk of foundation pit collapse is reduced, the side wall of the foundation pit is not supported by a large number of inclined supporting rods inside, a large construction space can be reserved for the foundation pit, and construction in the foundation pit is not influenced.

Description

Technical field [0001] The present application relates to the field of foundation pit support, and in particular, there is a construction foundation pit support structure. Background technique [0002] Building foundation pit is one of the main construction projects in construction, the common problem of building foundation pits, except for drainage, the main thing is the problem of collapse of the base pit slope. Generally, the slope will be collapsed, and the prefabricated template is often covered by the slope, and then prevents the collapse of the foundation pit, and the part is protected by a template with a vertical mounted template with backfilling; [0003] Patent No. 201920092454.4 provides a construction foundation pit support structure including a strut disposed within a foundation pit, and a tapered head is provided with a tapered head, and two grooves are provided on the struts. A baffle is provided on the slot, and the slope of the foundation pit is filled with a ba...
