Description

Technical Field

[0001] The utility model relates to the technical field of formwork support, and more specifically, to a limited space foldable double-wall formwork support device. Background Art

[0002] During the construction of the basement civil air defense structure, some areas encountered problems such as enclosed single-opening rooms and those completely sealed on all three sides and the top except for a single opening. This confined space also presented limited operating space for shear wall formwork. After pouring, the confined space was narrow, the civil air defense door opening was small, and formwork removal was difficult. The quality of the concrete after pouring directly affected the subsequent use.

[0003] In the traditional vertical reinforcement of civil air defense walls, the space inside the civil air defense unit is small, the wall cross-section is large, and the distance between walls is small, which makes it difficult to reinforce and dismantle the formwork system. It is also difficult for construction workers to operate in the narrow space, resulting in idle work. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the present invention provides a foldable double-wall formwork support device for confined spaces. This device facilitates formwork installation and reinforcement in confined and narrow spaces, and facilitates removal and transport after concrete pouring. It is easy for construction workers to operate, and the formwork system is easy to remove after concrete pouring, making it easy to transport. This significantly improves worker efficiency and contributes positively to project cost reduction and efficiency gains.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A limited space foldable double-wall formwork support device includes a foldable formwork assembly, the foldable formwork assembly includes a first wall formwork and a second wall formwork, the first wall formwork is provided with first thick square wooden back ribs at equal intervals, the second wall formwork is provided with second thick square wooden back ribs at equal intervals, the first thick square wooden back ribs and the second thick square wooden back ribs are hinged by a rotating shaft steel bar, the first thick square wooden back ribs and the second thick square wooden back ribs are provided with supporting steel pipes, and the supporting steel pipes are fixed by positioning screws.

[0007] Steel pipe grooves are provided on the outer sides of the first thick square timber back ribs and the second thick square timber back ribs, and the steel pipe grooves are provided in an arc-shaped structure.

[0008] A pipe groove cushion layer is fixedly arranged on the steel pipe groove, and the pipe groove cushion layer adopts an arc-shaped sheet structure.

[0009] The first thick square wood back edges and the second thick square wood back edges are arranged at corresponding positions, and the adjacent first thick square wood back edges and the second thick square wood back edges are arranged in close contact.

[0010] The first wall formwork and the second wall formwork have the same width. When the angle between the first wall formwork and the second wall formwork is 180 degrees, the edges of the first wall formwork and the second wall formwork are arranged to fit together.

[0011] Two groups of positioning hooks are symmetrically arranged on the first wall formwork, and the positioning hooks are arranged on the back ribs of the first thick square wood.

[0012] The thickness of the first thick square timber back edge and the second thick square timber back edge are the same.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The use of foldable formwork components makes it easy to install and reinforce the formwork in confined and narrow spaces, and easy to dismantle and transport after pouring concrete. Moreover, only minor changes to existing woodworking materials are required to achieve twice the result with half the effort, without causing significant damage to on-site materials. The provision of steel pipe troughs facilitates the positioning of supporting steel pipes and improves support stability. The provision of pipe trough pads increases the structural strength of the device and reduces damage to the pipe troughs by supporting steel pipes. The provision of positioning hooks facilitates the lifting of foldable formwork components on-site. This device is easy for construction workers to operate, and the formwork is easy to dismantle after pouring concrete, which facilitates transportation after dismantling. This can greatly improve workers' construction efficiency and play a positive role in reducing costs and increasing efficiency of projects. BRIEF DESCRIPTION OF THE DRAWINGS
