TECHNICAL FIELD
[0001] The utility model relates to concrete floor technology field, specifically, relate to a thin layer full seamless concrete integral floor. BACKGROUND
[0002] With the intelligent upgrading of domestic industry and cold chain industry in recent years, and the gradual clarification of the trend of building up floors and multi-storey design buildings, the functional quality requirements for building floors and floor surfaces are becoming higher and higher, and the use function requirements tend to be diversified. In addition to the use function, high requirements are also put forward for the decoration appearance. Quality problems such as functional unsatisfactory demand, cracking, hollowing, poor flatness, and increasing maintenance and repair costs are common in the floor and floor surface engineering of more and more buildings. Quality problems such as shell, peeling, poor durability, discoloration and other quality problems of coating type surface layer floor also show a more and more common trend, resulting in quality claim disputes and social contradictions, which often causes great loss to the owners or users.
[0003] Traditional 50-80 thick thin plate floor usually adopts sweeping and bonding and surface cutting seam method, and all cutting seam areas and corner areas are very common and obvious. With the advancement of concrete shrinkage, the floor continues to crack and hollow at random. When the vehicle and other material handling equipment are crushed or loaded for use, the floor will continue to crack and even crack, and the saw cutting seam has poor durability and the edge is easily damaged. Usually, the floor under the industrial and logistics use is damaged within 2 years, which affects the use, especially in the industrial and cold chain logistics field, which even produces functional problems that cannot be repaired.
[0004] Therefore, a kind of seamless polished concrete integral floor is proposed in the patent with publication number CN221372780U, including lower layer, middle layer and surface layer from bottom to top;The middle layer includes first isolation film, insulation layer and second isolation film arranged from bottom to top. It can realize seamless floor under the premise of ensuring normal function of floor, so as to achieve the functional requirement of no maintenance in later period. But it is through the construction of multi-layer structure of floor, through the setting of middle layer isolation film, the constraint of lower layer to surface is reduced, so that the whole floor surface can freely slide when drying. Although it can achieve seamless, it cannot avoid the drying shrinkage of the floor surface, but only transfers the drying shrinkage to the whole sliding. This means that it is only suitable for small block floor seamless laying, and for large area floor laying, the cumulative amount of free sliding in horizontal plane is large, which is not easy to realize, and cracks are easy to produce. The upper layer and the base layer are not stable to ensure sliding connection, and hollowing, warping and other quality problems are easy to occur in later period. UTILITY MODEL CONTENTS

[0008] Preferably, the buried formwork is further provided with horizontal sub-compartment transfer bars for load transfer.
[0009] Preferably, the terrace layer is further provided with cushion blocks for fixing and supporting the sub-compartment transfer bars, fixing bars and binding steel bars for fixing the buried formwork.
[0010] Preferably, the fixing bars comprise first fixing bars supported at one end by the cushion blocks and second fixing bars for fixing and supporting the first fixing bars.
[0011] Preferably, the buried formwork comprises a first formwork arranged above the steel mesh and a second formwork arranged below the steel mesh, and the second formwork is connected to the first formwork in a staggered manner through the steel mesh.
[0012] Preferably, the terrace layer is further provided with single-layer bidirectional steel mesh for reducing the risk of cracking and panel surface embedded steel bars for fixing the steel mesh, and the steel mesh penetrates through the buried formwork as a whole.

The spacer and the fixing rib ensure the stability and positional accuracy of the compartmentalized load transfer bar, preventing displacement during construction. The fixing rib (including the first fixing rib and the second fixing rib) provides additional support, enhances the fixing effect of the embedded formwork, and improves the strength and stability of the overall structure.
[0016] The setting of the steel mesh significantly improves the crack resistance of the floor layer and reduces cracking caused by temperature changes and load effects. The steel mesh is integrally passed through the embedded formwork, ensuring the connection of each part and improving the structural integrity of the overall ground. The panel-embedded steel bar connects the base layer through its main part and supports the steel mesh, ensuring the stability and positional accuracy of the steel mesh. Through the above design, a seamless connection of the ground is achieved, improving the integrity and aesthetics of the ground. The durability and service life of the ground are significantly improved.
