[0002] Reinforced concrete ribbed slabs are composed of thin plates and rib beams with small spacing. Multiple rib beams are staggered to form a grid structure. Reinforced concrete ribbed slabs are usually formed by placing the formwork on the template in advance, pouring concrete, and removing the formwork and formwork after the concrete solidifies.

[0003] However, in the actual production process, part of the concrete will adhere to the formwork after solidification, which is not easy to remove. Usually, it is separated by knocking, which has poor effect. Therefore, those skilled in the art provide a formwork for a ribbed floor that is easy to demould to solve the problem.

[0007] Compared with the prior art, the present invention adopting the above structure has the following beneficial effects: 1) when the formwork shell and the floor slab cannot be separated, a tool can be inserted into the top groove, and the threaded rod can be rotated to make the threaded tube and the threaded rod threadedly connected, the threaded rod can be lowered, the annular plate can press down the vertical tube, and the push plate can press down the floor slab, so as to facilitate the separation of the formwork shell and the floor slab. After separation, the threaded rod can be reversed, and the push plate can be slowly reset under the elastic action of the spring to ensure the integrity of the top of the formwork shell; 2) the rotating frame is rotatably connected to the side block, and the formwork shell can be lifted by pulling the rotating frame.

[0008] As a preferred embodiment, a further technical solution of the above structure is:

[0009] Preferably, a top groove is provided at the top of the threaded rod, and the top groove is arranged in the shape of a regular hexagonal prism, so as to facilitate the rotation of the threaded rod by a tool.

[0010] Preferably, a guide frame is fixedly installed on the top edge of the push plate, and the guide frame is slidably installed in the top shell, which can guide the push plate and improve the stability of the push plate operation.

[0011] Preferably, two side blocks are symmetrically fixedly mounted on both sides of the top shell.
