Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a flippable clamping bracket device used for lowering a steel cage. Background Art

[0002] Steel cage refers to a prefabricated component used in construction. It is welded by steel bars to form a cage-like structure, which is used to assemble the steel skeleton completely before pouring concrete. This structure can provide the support and reinforcement required for concrete pouring, and at the same time ensure that the concrete has sufficient strength and durability after curing. Steel cages are usually used to reinforce and support concrete columns, walls, beams and other parts to improve the bearing capacity and overall stability of the structure.

[0003] At present, during the construction process, construction workers usually place the steel cage by directly pulling the steel cage manually. Since the cut ends of the steel cage are relatively sharp, it is easy to cut the palm when pulling it manually, and it is inconvenient to use force when lowering it, which makes it very inconvenient when installing the device. Therefore, a reversible positioning bracket device for lowering the steel cage is needed to improve the above problems. Utility Model Content

[0012] As a preferred solution of the utility model, a fixing rack is fixedly installed on one side of the top of the fixing frame close to the circular groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model provides a flip adjustment component and a clamping component to cooperate with each other in a flip positioning bracket device for lowering a steel cage. When in use, the clamping block is first flipped to move the clamping block out from between the meshing teeth of the moving block. At the same time, the rack is pressed downward to drive the rack to slide downward. When the rack slides, the rotating shaft is driven to rotate through the connecting block. When the rotating shaft rotates, the active bevel gear is rotated synchronously. When the active bevel gear rotates, the synchronously driven secondary bevel gear is rotated. When the secondary bevel gear rotates, the secondary bevel gear drives the intermediate shaft transmission threaded rod to rotate, and the position of the support block is adjusted. After adjustment, the clamping block is released. The clamping block will flip under the action of the torsion spring to limit the steel cages of different diameters, which is convenient for the function of lowering. The problem that the steel cage is usually lowered by directly pulling it by manpower when lowering it is solved. Since the cutting end of the end of the steel cage is relatively sharp, it is easy to cut the palm when manually pulling it, and it is inconvenient to use force when lowering it, which makes it very inconvenient to lower the device.
