Description

Technical Field

[0001] The utility model relates to the technical field of construction supports, in particular to a multi-angle self-adaptive adjustable support. Background Art

[0002] The buckle bracket is a commonly used formwork support method for cast-in-place concrete beams and cast-in-place slabs. It is widely used in the cast-in-place construction of brackets for bridges, culverts and house construction projects. The traditional buckle bracket top support adopts a rigid connection between the top support plate and the screw rod, and the top support plate is installed in a horizontal state. However, in actual cast-in-place construction, the supported structure is often not horizontal, but at a certain angle. As a result, there is an installation angle and gap between the supported structure and the top support plate during installation, and they cannot fit tightly. This connection method will not only cause the top support plate and the supported structure to bend under the action of concentrated stress, but the eccentric pressure will also produce a bending moment on the bracket uprights, threatening the overall stability of the bracket. The traditional solution is to wedge a pad between the top support and the supported structure. This method is difficult to operate, has a huge workload, and requires a high labor force; the pad model cannot be unified and cannot be used in a turnover manner, resulting in material waste. In view of this, people have adopted angle-adjustable bracket top supports, and public literature has also reported some angle-adjustable bracket top supports, which are quoted as follows:
