Description

Technical Field

[0001] The utility model relates to the field of building construction, and more specifically, to a formwork hoop for a building square column. Background Art

[0002] In general, the cast-in-place columns of a building are load-bearing columns of the building, which are of reinforced concrete structure. Generally, the steel bar framework is tied first, and then column formwork is arranged outside the framework, and a formwork hoop is nested outside the formwork for reinforcing the formwork. Then, concrete is poured inside the formwork, and after consolidation, a building support column is formed.

[0003] The formwork hoop is mostly consistent with the column structure, square in shape, and composed of four plates lapped together. It is necessary to fasten the connection positions of each plate one by one, which is rather cumbersome and time-consuming in operation, and the efficiency is not high enough. Therefore, the hoop structure needs to be improved. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a formwork hoop for a building square column, which is fast, convenient and highly efficient.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A formwork hoop for a building square column includes a main L-shaped plate, a sub-L-shaped plate and a movable L-shaped plate. Both ends of the main L-shaped plate are provided with bayonet A, both ends of the sub-L-shaped plate are provided with bayonet B, and the sub-L-shaped plate is inserted and installed inside the bayonet A through the bayonet B. A threaded cylinder is arranged at the center of one side of the sub-L-shaped plate.

[0007] Further, a lead screw passes through the center of the threaded cylinder, and the lead screw and the threaded cylinder are connected by screw thread.

[0008] Further, a ring groove is provided at one end of the lead screw, and a handle is arranged at the other end of the lead screw.

[0009] Further, a U-shaped plate is welded to one side of the movable L-shaped plate, and a U-shaped socket is provided at one end of the U-shaped plate.

[0010] Further, the U-shaped plate is inserted and nested outside the ring groove through the U-shaped socket.

[0011] Compared with the prior art, the advantages of the utility model are as follows:

[0012] This solution cancels the straight plate-shaped materials, and the main L-shaped plate and the sub-L-shaped plate are clamped and connected, which is fast in installation. The threaded cylinder of the sub-L-shaped plate is penetrated by a lead screw, and a movable L-shaped plate is nested at one end of the lead screw. By rotating the lead screw, the movable L-shaped plate can be driven to move, so as to squeeze and fasten the formwork of square columns with different sizes, which is fast, convenient and highly efficient.
