Description

Technical Field

[0001] The utility model relates to the technical field of floor slabs, in particular to an anti-cracking floor slab structure for a rigid-elastic combined construction layer. Background Art

[0002] During the construction process of traditional floating, thermal insulation and sound insulation floors, materials such as polyurethane hard foam, thick extruded polystyrene insulation and sound insulation boards, and foamed polyethylene sound insulation pads are usually laid directly on the reinforced concrete floor base, and then a protective layer is built on top. However, this approach has obvious defects. Since the floating, thermal insulation and sound insulation layer materials are mostly elastic materials, their plasticity index is large and they are easy to deform. The fine stone concrete protective layer laid on these elastic materials is thin and has insufficient rigidity. It is difficult to effectively resist the stress caused by the deformation of the lower material, resulting in a large number of non-structural cracks in the floor.

[0003] Although this non-structural cracking will not affect the bearing capacity of the floor, it will have an adverse effect on the aesthetics and service life of the floor. In addition, cracking may also cause uneven settlement on the floor surface, which in turn affects the construction and use of the upper decorative layer. These problems not only increase the cost of later repairs and maintenance, but also affect the owner's experience. Utility Model Content

[0004] The purpose of the utility model is to overcome the problems in the background technology of insufficient rigidity of existing floors and easy deformation of the internal structure of the floors, which leads to non-structural cracking and uneven settlement and increased maintenance costs, and to provide a crack-proof floor structure for a rigid-elastic combined construction layer.

[0006] The rebound device is configured to transfer the force to the elastic layer and the rebound device when the first structural layer is subjected to force, so that the force is dispersed and buffered by the elastic layer and the rebound device.

[0007] The utility model discloses a floor structure for preventing cracking of a rigid-elastic combined construction layer. The floor structure comprises a first structural layer, and an elastic layer is arranged at the lower end of the first structural layer. The elastic layer has a buffering effect on the first structural layer. A rebound device is also arranged in the elastic layer. One end of the rebound device is connected to the first structural layer, and the other end is connected to the floor. The rebound effect of the elastic layer can be enhanced by the rebound device. Since the rebound device is a rigid structure, the first structural layer can transmit the force to the elastic layer and the rebound device in the elastic layer after being subjected to force. The rebound device of the rigid structure has a buffering and rebounding effect on the first structural layer. A part of the stress is offset by the rebound, and the stress on the first structural layer can be dispersed, so as to prevent the first structural layer from non-structural cracking and reduce the maintenance cost.

[0012] By connecting the cover plate to the first structural layer, the base to the floor, and providing a shock-absorbing spring between the cover plate and the base, it is ensured that the force exerted on the first structural layer can be directly transmitted to the elastic structure, and then transmitted from the elastic structure to the floor, ensuring uniform distribution of force and enhancing the shock-absorbing effect.

The cover plate and the first structural layer are fixed by a first bolt, and the first bolt is adapted to the first connecting hole and the second connecting hole.

[0014] This can ensure a stable connection between the cover plate and the first structural layer.

[0015] Preferably, a receiving groove is provided on a side of the cover plate facing the shock absorbing spring, and an elastic lining is provided in the receiving groove.

[0016] By providing a receiving groove at one end of the cover plate connected to the shock-absorbing spring, and arranging an elastic liner in the receiving groove, the shock-absorbing spring can further mitigate the impact during the rebound process.

[0017] Preferably, a third connecting hole is provided on the base, and a fourth connecting hole is provided on the floor. The fourth connecting hole has the same position and size as the third connecting hole.
