Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a supporting device. Background Art

[0002] During the wall construction of reinforced concrete building structures, it is necessary to control the thickness of the steel bar protective layer (i.e., the distance from the edge of the outermost steel bar to the concrete surface) to ensure that the reinforced concrete structure will not have casting defects such as exposed steel bars. In the traditional construction process, the method of controlling the thickness of the steel bar protective layer is: select a plastic pad, one end of the plastic pad is an open structure with a through hole, and the other end is a flat structure, insert the steel bar into the through hole through the opening structure, and then abut the other end of the plastic pad against the wall formwork, and then pour concrete in the wall formwork to form a wall structure. At this time, since the distance between the steel bar and the wall formwork is relatively fixed, the thickness of the steel bar protective layer is controlled. However, this type of pad is made of plastic material, with low structural strength, and is easily damaged during installation or pouring concrete, which affects the use effect; the axial thickness of the pad is small, and it is easy to tilt axially during the concrete pouring process, so that the thickness of the protective layer is not accurately controlled; the pad is fixed to the steel bar through the through hole, and the fixing method is not firm, and the pad is prone to fall off.

[0003] Therefore, the prior art discloses a reinforced concrete protective layer wheel positioning bracket, such as Figure 1 As shown, the positioning bracket includes a positioning sleeve 01, a placement sleeve 02 is provided inside the positioning sleeve 01, and the outer wall of the placement sleeve 02 is connected to the inner wall of the positioning sleeve 01 through multiple support components 03. Among them, the support component 03 is a retractable structure, and the support component 03 is fixedly connected to the positioning sleeve 01 by bolts 031. By providing the positioning sleeve 01, the placement sleeve 02 and multiple support components 03, the structural strength can be improved, and axial tilt is not easy to occur. By fixing the connection with bolts 031, the connection between the positioning bracket and the steel bar is tighter and not easy to fall off. However, since the size of the steel bar is not fixed during the construction process, the positioning bracket cannot adapt to steel bars of different sizes. Utility Model Content
