Description

Technical Field

[0001] This utility model relates to the field of flooring technology, and in particular to an anti-cracking flooring. Background Technology

[0002] Flooring refers to the surface structure of the interior or exterior ground of a building. It is mainly used to bear the flow of people, vehicles and various loads, while also serving as decoration and protecting the base layer. It is an important component of building floor engineering.

[0003] As a structural layer that directly bears the load, the performance of the floor directly affects the building's functionality and lifespan. Currently, in building engineering, floor structures are subject to long-term effects from factors such as temperature changes, foundation settlement, load impact, and chemical corrosion, which can easily lead to cracks, shortening the service life, increasing maintenance costs, and reducing practicality. Therefore, it is necessary to redesign a crack-resistant floor to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-cracking flooring.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A crack-resistant floor includes a foundation, which comprises, from bottom to top, a crack-resistant steel mesh layer, a base layer, a waterproof layer, a reinforcing layer, a buffer layer, an anti-corrosion layer, and a wear-resistant layer. The crack-resistant steel mesh layer is disposed inside the base layer and is intertwined and tied together. The base layer is made of poured concrete and completely covers the crack-resistant steel mesh layer.

[0007] Preferably, the waterproof layer comprises a polymer waterproof membrane layer and a penetrating crystalline waterproof coating layer, wherein the waterproof membrane layer is made of EPDM rubber.

[0008] Preferably, the reinforcing layer is a fiber-reinforced concrete layer, the fiber is made of polypropylene fiber, and a mechanical interlocking interface is provided between the reinforcing layer and the base layer to improve the interlayer bonding force.

[0009] Preferably, the buffer layer is made of closed-cell foam material, wherein the cell structure of the closed-cell foam material is independent and uniformly distributed.

[0010] Preferably, the anti-corrosion layer is a resin-based composite material coating, wherein the composite material comprises a flake reinforcement and a corrosion-resistant resin matrix.

[0011] Preferably, the wear-resistant layer is a ceramic particle-reinforced polymer matrix composite material, wherein the ceramic particles are uniformly distributed in the polymer matrix to form a wear-resistant skeleton structure.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up a crack-resistant steel mesh layer and a polypropylene fiber reinforcement layer, a rigid-flexible dual crack-resistant system is formed. The steel mesh provides structural support and restricts concrete deformation, while the polypropylene fiber disperses stress and prevents the expansion of micro-cracks, effectively improving the crack resistance of the floor.

[0014] 2. By setting up an anti-corrosion layer and a wear-resistant layer with overlapping scales to form a complex structure, chemical media can be blocked from entering. The ceramic particle-reinforced wear-resistant layer, with its high-hardness ceramic particles, significantly improves surface wear resistance and extends the service life of the floor.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 A crack-resistant floor includes a foundation 1, which comprises, from bottom to top, a crack-resistant steel mesh layer 2, a base layer 3, a waterproof layer 4, a reinforcing layer 5, a buffer layer 6, an anti-corrosion layer 7, and a wear-resistant layer 8. The crack-resistant steel mesh layer 2 is located inside the base layer 3 and is intertwined. The base layer 3 is made of concrete and completely covers the crack-resistant steel mesh layer 2. The base layer 3 is made of concrete and utilizes its high compressive strength to provide a solid support foundation for the upper structure. The combination of the two greatly enhances the floor's ability to resist cracks caused by foundation settlement and temperature changes.

[0022] The waterproof layer 4 includes a polymer waterproof membrane layer and a penetrating crystalline waterproof coating layer. The waterproof membrane layer is made of EPDM rubber. EPDM rubber waterproof membrane has excellent weather resistance, flexibility and puncture resistance. It can form a continuous and dense waterproof membrane on the surface of the base layer 3 to block external moisture intrusion. The penetrating crystalline waterproof coating can penetrate into the concrete and react with cement hydration products to generate crystals, filling pores and micro-cracks, thereby improving the waterproof performance of the base layer 3 from the inside.

[0023] The reinforcing layer 5 is a fiber-reinforced concrete layer, with polypropylene fibers. A mechanical interlocking interface is provided between the reinforcing layer 5 and the base layer 3 to improve the interlayer bonding force. The polypropylene fibers are evenly dispersed in the concrete, which can effectively prevent the generation and expansion of micro-cracks inside the concrete and improve the toughness and crack resistance of the concrete.

[0024] The buffer layer 6 is made of closed-cell foam material. The cell structure of the closed-cell foam material is independent and evenly distributed. The independent cell structure of the closed-cell foam material gives it good elasticity and buffering performance, which is beneficial when the floor is subjected to thermal expansion and contraction stress caused by temperature changes.

[0025] The anti-corrosion layer 7 is a resin-based composite material coating. The composite material includes flake reinforcement and corrosion-resistant resin matrix. The flake reinforcement is arranged in parallel overlapping patterns in the corrosion-resistant resin matrix, which can effectively extend the penetration path of corrosive media and greatly slow down the erosion rate of chemical substances on the internal structure of the floor.

[0026] The wear-resistant layer 8 is a ceramic particle reinforced polymer matrix composite material. The ceramic particles are uniformly distributed in the polymer matrix to form a wear-resistant skeleton structure. The ceramic particles have extremely high hardness and wear resistance. After being uniformly dispersed in the polymer matrix, they constitute the main load-bearing and wear-resistant part of the wear-resistant layer 8, which can effectively resist the wear caused by people, vehicles walking and goods being dragged.

[0027] When using this utility model, the foundation 1 is first leveled and compacted to ensure that the surface of the foundation 1 is flat and dense, laying a stable foundation for subsequent construction. Then, the anti-crack steel mesh layer 2 is tied. The ribbed steel bars are laid crosswise according to the design requirements and firmly tied at the intersection with wire to prevent the steel mesh from shifting during subsequent construction. After the tying is completed and the inspection is qualified, the concrete of the base layer 3 is poured. Commercial concrete with appropriate strength grade is selected and poured evenly by pumping. It is then fully vibrated and compacted with a vibrator to ensure that the concrete and the steel mesh are tightly bonded. After the pouring is completed, the base layer 3 is cured in time. When its strength reaches the requirements, the surface of the base layer 3 is roughened with professional tools to enhance the bonding effect with the reinforcing layer 5.

[0028] Next, the construction of the reinforcing layer 5 is carried out. Polypropylene fibers are evenly mixed into the concrete and thoroughly stirred to ensure that the fibers are evenly dispersed. Then, the fiber-reinforced concrete is laid on the base layer 3 and vibrated a second time with a vibrating device to improve the density. After the surface has absorbed the water, it is troweled. When constructing the waterproof layer 4, the surface of the reinforcing layer 5 is first coated with penetrating crystalline waterproof coating in two coats to ensure complete coverage without any omissions. After the coating dries, the EPDM rubber waterproof membrane is laid. The laying direction of the membrane is determined according to the actual situation to form a complete waterproof system.

[0029] The buffer layer 6 uses closed-cell foam material to ensure its integrity, thereby effectively dispersing various stresses. During the construction of the anti-corrosion layer 7, glass flakes and vinyl ester resin are mixed in proportion, and curing agent and accelerator are added and stirred evenly. Multiple layers are sprayed using high-pressure airless spraying equipment. The construction interval between each layer is adjusted according to the resin curing status to ensure coating quality. Finally, the wear-resistant layer 8 is constructed by thoroughly mixing ceramic particles and polyurethane resin, adjusting to a suitable construction viscosity, and then evenly applying it to the surface of the anti-corrosion layer 7 using a trowel application process. During the construction process, surface air bubbles are eliminated. After the wear-resistant layer 8 is completely cured, the floor surface is polished to give the floor good crack resistance, wear resistance, and aesthetics.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
