Description

Technical Field

[0001] The present application relates to the technical field of floor slab formwork, and more specifically, to a floor slab formwork. Background Art

[0002] In building construction, the floor formwork is usually supported by supporting rods or beams on the roof, and the floor is formed by setting a steel cage on the top of the floor formwork and casting concrete after solidification. After the floor is formed, the formwork is removed from the bottom to achieve cast-in-place construction of the floor.

[0003] The document with the prior art publication number CN201730314U provides a building floor template, which includes the groove module, a support beam, bolts or pins or threads. The groove module is composed of a top plate and two side plates. There are demoulding bolt holes on the top plate of the groove module constituting the template, and demoulding bolts are fixed on it. When demoulding, the demoulding bolts fixed on the demoulding bolt holes are screwed to the outside of the top plate to separate the top plate of the groove module from the poured concrete, so as to achieve the purpose of quick demoulding. The building floor template is composed of a groove module, and there are holes on its side plates. When assembling the floor template, a number of groove modules are neatly arranged on the support beam, and bolts or pins or threads are passed through the holes to connect two adjacent groove modules to form an integral building floor template.

[0004] Although the above-mentioned prior art solutions can achieve the relevant beneficial effects through the structure of the prior art, they still have the following defects:

[0005] The ends of the trough-shaped modules are connected by connecting strips. The modules at the connecting strips are not a whole. When subjected to vertical loads, the bearing capacity of the connecting strips is low, which will cause the formwork to sink and bend at the connecting strips, which is not conducive to the casting and forming of the floor slab.

[0006] Regarding the above-mentioned related technologies, the inventor believes that the ends of the trough-shaped modules are connected by connecting strips, and the modules at the connecting strips are not a whole. When subjected to vertical loads, the bearing capacity of the connecting strips is low, which will cause the formwork body to sink and bend at the connecting strips, which is not conducive to the casting and forming of the floor slab.

[0007] In view of this, we propose a floor formwork. Utility Model Content
