Description

Technical Field

[0001] The invention relates to the technical field of large-area cast-in-place concrete wear-resistant floor construction, and in particular to a rotatable leveling and reinforcement device and method for armored seams. Background Art

[0002] With the development of industry and commerce, the performance requirements for flooring are getting higher and higher. Wear-resistant flooring is widely used in factory workshops, warehouses, parking lots and other places due to its excellent wear resistance. However, due to factors such as temperature changes, concrete shrinkage and uneven foundation settlement, cracks are prone to occur in the floor. In this case, in order to ensure the integrity and stability of the wear-resistant floor and reduce the impact of cracks on the function and appearance of the floor, armored seams came into being.

[0003] The floor armored seam is mainly composed of edge protection flat steel, force transmission steel plate, floor compartment seam steel plate, force transmission plate telescopic sheath, easy-to-break plastic bolts, etc. It is a finished floor compartment seam device with template compartment function, no need to dismantle, avoiding cracking, settlement, shrinkage and deformation. The self-breaking plastic screws ensure that the armored seam automatically separates as the concrete shrinks.

[0004] The armored seam has good expansion and contraction performance and load-bearing capacity, and can adapt to various deformations of the wear-resistant floor during use, effectively preventing the generation and expansion of cracks, thereby extending the service life of the wear-resistant floor and maintaining its good performance and appearance.

[0005] Traditional armor seam installation requires the assistance of a gantry and the use of a laser level to adjust and check the armor seam top elevation, vertical verticality, and centerline position deviation of the separation seam. After the verification is completed, the steel support is directly welded to the armor seam. Each standard armor seam generally has no less than four fixed points, thereby achieving the purpose of reinforcing the armor seam.

[0006] There are many limitations when the gantry adjusts the position of the armor seam. After the armor seam is lifted, if the rigidity of the corner protection flat steel after multiple pieces of the armor seam are connected is insufficient, it will cause bending, thus affecting the flatness of the floor and the longitudinal straightness of the armor seam.

[0007] During the installation of traditional armor seams, steel bar brackets are used to fix the armor seams by welding. The quality of on-site welding cannot be guaranteed, and the reinforcement is often loose. After the concrete is poured, the steel bars fixing the armor seams are cut off, and the reinforcing steel bars cannot be reused, resulting in a large waste.

[0008] During the welding process, the PE film laid on the ground is easily burned, destroying the anti-seepage and moisture-proof effect of the PE film on the floor. At the same time, there are many combustibles during cross-operation at the construction site, and there is a fire hazard when performing electric welding operations.

[0009] Therefore, it is necessary to provide an armor seam leveling and reinforcement device, which can avoid the problem of PE film being easily burned during welding operations when reinforcing armor seams, eliminate fire hazards and be reusable; and solve the problem of armor seams bending due to insufficient overall rigidity, resulting in excessive deviation in floor flatness. Summary of the invention
