Description

Technical Field

[0001] The utility model relates to an easily detachable support structure for a small space of a precast roof slab, belonging to the technical field of aluminum formwork support devices for construction. Background Art

[0002] Aluminum formwork is a building formwork made of aluminum alloy, which has excellent mechanical properties, is easy to construct and install, easy to disassemble, has good forming effect, does not generate construction waste, has a high turnover rate, and has a high recyclable value; it is suitable for complex construction environments, solves the defects of traditional formwork in the past, ensures the forming effect, and is convenient for installation and disassembly. As of April 2024, the national market inventory of aluminum alloy formwork is about 69.5 million square meters, and there are about 700 enterprises engaged in the processing, R & D design, production and processing, and leasing contracting of aluminum alloy formwork equipment in the country. With the increasing requirements of projects for convenient and fast construction and forming quality, various construction schemes have been developed, such as: the combination of aluminum and wood, and the combination of cast-in-place and precast. Then, the support and disassembly of the small space of the roof slab in the combination of cast-in-place and precast have become construction problems. Existing support structures are difficult to achieve both convenient disassembly and assembly and ensure the forming effect at the same time, and are insufficient to meet the project requirements.

[0003] Such as Figure 9 The project structure shown is composed of precast roof slabs, precast walls, cast-in-place walls, and cast-in-place joints. In order to facilitate disassembly and assembly, this scheme uses easily detachable C-grooves and double-sealed eight-shaped easily detachable C-grooves assembled with aluminum formwork and C-grooves. Since the precast wall part does not require the configuration of aluminum formwork, resulting in insufficient support, a scheme is adopted in which screw holes are reserved in advance on the precast wall, and screws are used to pass through the C-groove, the reserved screw holes in the precast wall, and the opposite precast roof slab C-groove for connection and fixation during formwork preparation. Since this scheme requires the pre-reservation of screw holes on the precast wall, the holes reserved on the precast wall need to be blocked after the project construction is completed, increasing the construction volume. When using screws for reinforcement, screw openings need to be opened on the C-groove, increasing the repair cost for the repeated use of the C-groove. In this scheme, the roof slab is fully configured, increasing the usage amount of the formwork, increasing the construction cost, and the forming effect of the roof slab part is not very ideal due to the lack of support. Therefore, it is very necessary to design an easily detachable support structure for a small space of a precast roof slab with convenient installation and disassembly and good construction forming quality. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an easily detachable support structure for a small space of a precast roof slab with convenient installation and disassembly and good construction forming quality.

[0005] To achieve the above object, the utility model adopts the following technical solutions.

[0015] 1. In the present utility model, both the L-shaped component and the intermediate component are provided with easily detachable inclined plates as break openings, avoiding the problem of being unable to be removed due to the inward extrusion during concrete pouring. In addition, the intermediate component is supported by support rods, and the L-shaped component is supported by a connection component and support rods, with the overall support performance being stable. Therefore, the present utility model has low manufacturing cost, is convenient and fast to install and disassemble, can be used repeatedly, and realizes convenient disassembly and assembly while providing stable support to improve the forming effect.
