Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of concrete floor, specifically, relates to a leveling layer polished concrete integral floor. BACKGROUND

[0002] Leveling layer polished concrete is a commonly used ground treatment technology in modern architecture. It combines the functions of leveling layer and the aesthetics and durability of polished concrete, providing an economical, efficient and environmentally friendly ground solution for buildings. Leveling layer is mainly used to solve the flatness problem of the original ground, ensuring the quality of subsequent construction. The polished concrete surface after special treatment is smooth and high in gloss, with good visual effect. Leveling layer polished concrete floor is widely used in commercial buildings, industrial plants, parking lots, warehouses and other places, and is particularly suitable for places that need to bear heavy load and frequent traffic due to its excellent performance.

[0003] Leveling layer polished concrete may encounter problems such as hollowing and warping during construction. These problems not only affect the appearance quality of the ground, but also may affect its performance and service life. There are parts that are not completely compacted between the leveling layer and the base layer or inside the leveling layer, forming cavities or gaps. When knocking on these areas, it will make a hollow sound, and in severe cases, it may cause the ground to crack or fall off. The lack of adhesion between the leveling material and the base layer may be caused by improper handling of the base layer (such as too smooth surface, oil stains), inappropriate selection of leveling material or improper control of moisture during construction.

[0004] Warping refers to the bending deformation phenomenon of the leveling layer or polished concrete surface, usually manifested as the middle part protruding upwards or downwards, and the edges accordingly concave or warped. Thermal expansion and contraction caused by temperature changes is one of the main reasons for warping. If the leveling layer or polished concrete is affected by rapid temperature difference during the curing process, it is easy to produce internal stress, thus causing deformation.

[0005] Therefore, the industrial floor anti-hollowing and anti-cracking concrete leveling layer construction method proposed in the patent with publication number CN115126242A can effectively prevent the concrete leveling layer from being hollow and damaged, and can effectively control and prevent the concrete leveling layer from cracking and being damaged. It achieves the above effects by combining the floor bonding layer, concrete material selection, and anti-cracking mesh implantation process. However, the installation of the anti-cracking mesh requires certain skills and experience, especially the fixing of the mesh and ensuring its correct position in the concrete. If the construction personnel lack experience, it may cause the mesh to shift or not be fixed firmly. Installing the anti-cracking mesh increases the construction time, especially in large projects, which may affect the progress of the entire project. During the concrete pouring and vibrating process, the mesh may shift, causing it to not function fully. If the mesh shifts severely, it may need to be reinstalled. During the pouring process, if the vibrating is not sufficient, bubbles and cavities may form around the mesh, affecting the compactness and strength of the concrete. Utility model content
