Description

Technical Field

[0001] The utility model relates to a cantilever structure casting formwork supporting device. Background Art

[0002] Cantilever concrete structure is an important part of construction projects. Cantilever structures are usually eaves, cantilever corridors, balconies, awnings and some decorative cantilevers. Its characteristics are that the cantilever length is compensated and the load is not large. When pouring cantilever concrete, construction workers need to set up corresponding formwork frames on the scaffolding outside the building to complete the pouring operation of the cantilever concrete structure. This construction method increases the construction time of construction workers outside the building, which is not conducive to ensuring the safety of construction workers. In order to solve this technical problem, a Chinese utility model patent with authorization announcement number CN210685393U discloses a formwork frame for an eave cantilever concrete structure, including a casting mold arranged on the outside of a building for casting an eave cantilever concrete structure, and also including a support frame and an extension frame arranged inside the building, the support frame is tightly against the top surface and the bottom surface inside the building; the extension frame includes an extension rod fixed to the support frame in the middle and a connecting rod fixed to the bottom of the casting mold; the extension rod is arranged at an angle, one end of the extension rod extends out of the building and is fixed to the connecting rod, and the other end is arranged inside the building and fixed to the bottom surface inside the building. Although the above-mentioned Chinese utility model patent effectively shortens the construction time and ensures the safety of construction workers; however, although the middle part of the extension rod of the extension frame is fixed on the support frame, the pressure of the cantilevered concrete structure on the extension rod is partially shared by the support frame, and part of the force still acts on the extension rod. The bottom end of the extension rod fixed to the bottom surface of the building is prone to tilt and lose its supporting function; on the other hand, since a mounting plate is fixed at one end of the extension rod located in the building, the mounting plate is fixed to the bottom surface of the building by fastening bolts, so that an extension rod of one length can only be used for buildings with the same floor height. For buildings with different floor heights, extension rods of different lengths need to be customized, which causes a waste of resources. Utility Model Content

The wheel 23 is meshed with a driving gear 24, and the driving gear 24 is equipped with a motor. When the motor is started, the driving gear 24 drives the adjacent driven gear 23 to rotate, and the rotation of the rotating rod 21 realizes the first base 1 to move toward or in the opposite direction. The first base 1 is provided with a top support member 3 at one end facing the building interior, and the top support member 3 is used to press the first base 1 against the bottom plate in the building interior to limit the movement of the first base 1. The top support member 3 includes a first sleeve 31, and the upper and lower ends of the first sleeve 31 are threadedly connected with a clamping rod 32. The clamping rod 32 is raised by rotating the clamping rod 32, and the clamping rod 32 is pressed against the bottom plate and top plate in the building interior to avoid warping or displacement, thereby reducing stability and safety.The first base 1 is provided with a length slide groove 11 and a circular hole is opened at the end of the length slide groove 11, and the second base 4 is slidably connected to the length slide groove 11, and the second base 4 is provided with a threaded groove corresponding to the circular hole.
