[0001] This utility model relates to the field of building engineering, and in particular to a recyclable and reusable temporary support structure. Background Technology

[0002] Temporary support structures refer to temporary support systems set up during construction, tunnel excavation, mining operations, or underground space development to ensure worker safety and the smooth progress of the project. These structures are mainly used to prevent soil, rock, or other materials from collapsing or shifting after excavation.

[0003] For example, the temporary support structure for foundation pits to prevent deformation of adjacent building foundations, as disclosed in publication (announcement) number CN219011236U, includes a support base, support side plates, ground nails, and support columns. The support base is fixed to the bottom of the foundation pit by ground nails. The support side plates are mounted on the support base. One end of the support column is hinged to the support base, and the other end of the support column is movably engaged with the support side plates. This utility model has the effect of improving the impact of water seepage on the foundation pit support structure and enhancing the stability of the foundation pit support structure. However, because the entire utility model is inconvenient to disassemble, requiring the use of auxiliary tools to pull out the ground nails, it is not convenient to individually recycle and reuse each component, which is quite inconvenient.

[0004] Therefore, it is necessary to design a temporary support structure that can simultaneously fix the nails in place and support the support plate, thereby improving stability, and is easy to disassemble, use, recyclable, and reusable. Utility Model Content

[0005] To overcome the shortcomings of existing temporary support structures, such as the inconvenience of disassembling the entire structure, the need to use auxiliary tools to pull out the ground spikes, and the inconvenience of recycling individual components, this utility model provides a temporary support structure that can simultaneously lock the fixing spikes in place and support the support plate, thereby improving stability, and is easy to disassemble and use. It is also recyclable and reusable.

[0006] The technical solution is: a recyclable and reusable temporary support structure, including a support plate, an assembly plate, a guide frame, a screw rod, fixing nails, and a snap-fit ​​assembly. The rear of the support plate is connected to the guide frame, and the assembly plate is slidably connected to the guide frame. The middle of the support plate is rotatably connected to the screw rod, which is threadedly connected to the assembly plate. Fixing nails are sleeved on both the left and right sides of the assembly plate, and the fixing nails all pass through the support plate. The assembly plate is provided with a snap-fit ​​assembly that can lock the fixing nails in place and support the support plate at the same time.

[0007] As a preferred technical solution of this utility model, the upper part of the fixing nail is provided with a mating hole.

[0008] As a preferred technical solution of this utility model, it also includes splicing blocks and pins, with splicing blocks connected to the left side of the support plate and pins snapped into the front right side of the support plate.

[0009] As a preferred technical solution of this utility model, it also includes a rotating handle, and the rotating handle is connected to the upper side of the lead screw.

[0010] As a preferred technical solution of this utility model, the snap-fit ​​assembly includes a connecting rod, a first snap-fit ​​rod, a second snap-fit ​​rod, and a snap-fit ​​block. The first snap-fit ​​rods are snapped onto both the left and right sides of the assembly plate. The fixing nails are snapped onto the adjacent first snap-fit ​​rods through the mating holes. A connecting rod is connected between the first snap-fit ​​rods. The upper sides of both the left and right sides of the connecting rods are connected to the second snap-fit ​​rods. The second snap-fit ​​rods are snapped onto the support plate. The snap-fit ​​blocks are snapped onto both the left and right sides of the assembly plate. The snap-fit ​​blocks are in contact with the connecting rods.

[0011] As a preferred technical solution of this utility model, the card block has an n-shaped structure.

[0012] Beneficial effects: 1. This utility model achieves the effect of locking the fixing nail while supporting the support plate, improving stability, and facilitating disassembly and use by pulling out the locking block, moving the connecting rod forward to remove it, and then turning the handle to drive the screw to rotate, so that the assembly plate moves upward under the action of the thread, and drives the fixing nail to move upward and pull it out from the ground.

[0013] 2. This utility model connects the splicing block to the right side of the support plate to be spliced, and then inserts a pin into the support plate so that the pin contacts the splicing block. The pin limits the splicing block, thus achieving the effect of facilitating the splicing of the support plate and adapting to different usage needs. Attached Figure Description
