Description

Technical Field

[0001] This invention relates to the field of composite slab technology, specifically to a prefabricated composite slab reinforcement structure and reinforcement method. Background Technology

[0002] Composite floor slabs are assembled monolithic floor slabs made by stacking precast slabs and cast-in-place reinforced concrete layers. Composite floor slabs have good integrity, and the upper and lower surfaces of the slab are flat, which facilitates the finishing layer decoration. They are suitable for high-rise buildings and large-span buildings with high requirements for overall rigidity.

[0003] A Chinese patent document with publication number CN218479383U discloses a user-friendly prefabricated composite slab, which includes a composite slab, specifically a precast concrete layer. Symmetrically arranged smoothing layers are fixedly installed on the upper and lower surfaces of the precast concrete layer, and a reinforcing mesh is provided inside the precast concrete layer. The design uses multiple inserts on one side of the outer wall of the composite slab to allow two composite slabs to be pre-assembled before installation. The user inserts the inserts on one composite slab into the corresponding slots on the other, achieving rapid assembly between the two composite slabs. This allows for manual assembly to the appropriate size before installation on a building, facilitating the division of labor between two groups of workers to quickly complete the assembly of the precast composite slabs. It also helps to strengthen the connection strength between the two slabs after subsequent installation.

[0004] In the above-mentioned schemes and existing technologies, when manufacturing composite slabs, the ribs are generally assembled according to the manufacturing requirements before precasting. The main support rods are arranged at equal intervals on the reinforcing mesh, but they lack corresponding fastening and positioning structures. They are either tightened with iron bars, which provides a certain degree of tightness, but if problems occur during operation and need to be removed, it will cause trouble. Furthermore, the existing reinforcing mesh is generally set up vertically, and after casting, the strength of its side positions will be weak, which cannot meet the usage requirements.

[0005] Therefore, we need a prefabricated composite slab reinforcement structure and reinforcement method to solve the problem of the lack of corresponding reinforcement components for the prefabricated ribs of composite slabs under the existing technology mentioned above, so as to improve the strength of composite slab manufacturing.

The cylindrical through slot is located at the corner of the stabilizing frame. Connecting threads are symmetrically provided at both ends of the reinforcement rod. The locking slot is equidistantly provided on the side walls at both ends of the reinforcement rod. The connecting threads are threadedly connected to the internal threaded fastening ring.
