Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a crack-resistant, large-area seamless floor structure. Background Technology

[0002] As a crucial component of a building's foundation that directly contacts the soil, the floor not only bears the load of the ground-floor rooms but also fulfills multiple functions such as moisture-proofing, waterproofing, insulation, and wear resistance. Its design and construction require specific materials and processes to ensure that the floor's aesthetic appeal and functionality are fully realized.

[0003] In practical applications, floor structures are typically composed of rigid materials such as concrete. However, these materials are subject to various factors during use, leading to changes in their properties. Concrete, in particular, often develops micro-cracks during the hardening process due to its inherent shrinkage stress. Furthermore, the floor is subjected to external loads during normal use, such as foot traffic and equipment movement, which exacerbate cracking. Cracks directly reduce the floor's durability and shorten its service life. Utility Model Content

[0004] This utility model provides a crack-resistant, large-area seamless floor structure to solve the technical problems existing in the prior art, which can improve the durability of the floor and extend its service life.

[0005] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is: a crack-resistant large-area seamless floor structure, comprising a base layer, a moisture-proof layer, a micro-resistance layer, a prestressed concrete layer and a surface layer arranged sequentially from bottom to top, wherein an acrylic primer layer is coated on the base layer, and the micro-resistance layer is made of elastic soft pads.

[0006] The prestressed concrete layer is provided with a prestressed steel mesh, which is supported by a support member and fixed to the micro-resistivity layer.

[0007] The support member is provided with a support base, on which a sleeve is vertically fixed. A height-adjustable support rod is inserted into the sleeve. A steel bar support is fixed to the top side of the support rod, and a through-tube is provided on the steel bar support.

[0008] The surface layer includes a diamond abrasion wear-resistant layer and a waterproof layer arranged sequentially from top to bottom.

[0009] Anti-slip particles are provided on the top of the diamond abrasion wear-resistant layer.

[0010] The waterproof layer is made of polyurethane coating.

[0011] The moisture-proof layer is made of a moisture-proof film.

[0012] A heat insulation layer is also provided between the moisture-proof layer and the micro-resistance layer.

[0013] An anti-corrosion surface layer is provided between the surface layer and the prestressed concrete layer.

[0014] The insulation layer is made of polystyrene foam board or rock wool board.

[0015] The advantages and positive effects of this invention are as follows: By setting a prestressed concrete layer and a micro-resistance layer, cracks caused by shrinkage stress and external loads during the hardening and use of concrete can be effectively reduced, thereby improving the crack resistance of large-area seamless flooring, enhancing its durability, and extending its service life. Simultaneously, the combined design of the base layer, moisture-proof layer, micro-resistance layer, prestressed concrete layer, and surface layer not only enhances the flooring's load-bearing capacity but also provides multiple functions such as moisture resistance, waterproofing, and wear resistance, meeting the needs of different application scenarios.

[0022] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0023] Example 1:

[0024] Please see Figures 1-4A crack-resistant, large-area seamless floor structure includes, from bottom to top, a base layer 1, a moisture-proof layer 2, a micro-resistance layer 3, a prestressed concrete layer 4, and a surface layer 5.

[0025] An acrylic primer layer is coated on the base layer 1.

[0026] The micro-resistance layer 3 is constructed using an elastic pad, which can be made of materials such as rubber, polyurethane foam, or composite materials of rubber and polyester fibers. The main function of the micro-resistance layer 3 is to absorb and disperse the impact force on the floor, improving its comfort and safety. The elastic pad in the micro-resistance layer 3 provides excellent elasticity, enabling it to absorb and disperse impact forces.

[0027] The more preferred solution in this embodiment is as follows:

[0028] The prestressed concrete layer 4 is provided with a prestressed steel mesh 42, which is supported by a support member 41, and the support member 41 is fixed on the micro-resistance layer 3.

[0029] Considering that the prestressed steel mesh 42 is laid out in a crisscross pattern, the longitudinal prestressed steel bars are placed on top of the transverse prestressed steel bars, and then the steel bars in both directions are tied together. However, because the prestressed steel bars are relatively long, the longitudinal prestressed steel bars are not easy to position and fix during the laying process, and they may slide on the transverse prestressed steel bars. Furthermore, the prestressed steel mesh 42 needs to be at a certain height from the micro-resistance layer 3, and the height is not easy to adjust and position when laying the prestressed steel mesh 42. Therefore, the support member 41 adopts the following structure: a support base 410 is provided, a sleeve 411 is vertically fixed on the support base 410, a height-adjustable support rod 412 is inserted into the sleeve 411, a steel bar support 413 is provided on the top side of the support rod 412 and is fixed to it, and a through-bar pipe 414 is provided on the steel bar support 413. This structure allows for adjustable support height, which facilitates effective support for the transverse and longitudinal bars of the steel mesh.

[0030] During construction, the support base 410 should be fixed to the micro-resistive layer 3, ensuring its stability. Specifically, the negative pressure adsorption of suction cups can be used to connect the support base 410 to the micro-resistive layer 3. Multiple suction cups can be installed on the bottom of the support base 410, either by attaching them to the marked positions on the bottom of the support base 410 or by peeling off the adhesive backing paper directly onto the bottom of the support base 410. If the suction cups have adhesive backing, the backing paper can be removed directly, and the suction cups can be attached to the bottom of the support base 410. If there is no adhesive backing, a small amount of glue can be used to fix the suction cups, pressing them onto the micro-resistive layer 3 to firmly adhere the support base 410 to it. This method of installation and removal of the support base 410 is very simple and will not cause physical damage to the micro-resistive layer 3.

[0031] Alternatively, a reversible adhesive can be used to connect the support base 410 to the microresistive layer 3. A reversible adhesive, such as double-sided tape or temporary adhesive, is applied to the bottom of the support base 410. The support base 410 is then fixed to the microresistive layer 3 using the adhesive. This process does not cause physical damage to the microresistive layer 3. Residue can be removed by heating or using a solvent.

[0032] During construction, the support components 41 are distributed in both the horizontal and vertical directions according to the design requirements.

[0033] The surface layer 5 includes a diamond abrasion wear-resistant layer 51 and a waterproof layer 52 arranged sequentially from top to bottom.

[0034] Anti-slip particles are provided on the top of the diamond abrasion wear-resistant layer 51. The anti-slip particles can be diamond abrasion particles or quartz sand particles.

[0035] The waterproof layer 52 is made of polyurethane coating.

[0036] The moisture-proof layer 2 is constructed using a moisture-proof film, which can be a PE film. PE film is a polypropylene plastic film with good waterproof and heat-sealing properties. Its surface can be treated to form a textured surface, further enhancing the moisture-proof effect. PE film is soft, easy to install, and relatively inexpensive.

[0037] Construction method of Example 1 above:

[0038] First, the ground base layer 1 is cleaned to ensure it is free of debris and oil stains, and meets certain flatness requirements. An acrylic primer layer is applied to the surface of base layer 1 to enhance the adhesion between base layer 1 and the moisture-proof layer 2, and to prevent moisture erosion of base layer 1. A moisture-proof film of a predetermined thickness is then laid on top of the acrylic primer layer. This moisture-proof film effectively isolates groundwater vapor from eroding the upper structure, improving the durability of the floor. According to design requirements, supports 41 are installed on the micro-resistance layer 3, and prestressed steel mesh 42 is laid out in a crisscross pattern on the supports 41 as designed. The longitudinal prestressed steel bars overlap the transverse prestressed steel bars and are securely connected using ties, welding, or other connection methods. Then, concrete 43 is poured, ensuring that it fully encapsulates the prestressed steel mesh 42 and the supports 41. During pouring, attention is paid to compaction to prevent voids from forming inside the concrete 43. A waterproof layer 52 is laid on top of the prestressed concrete layer 4 to prevent moisture from penetrating into the prestressed concrete layer 4. A corundum wear-resistant layer 51 is then laid on top of the waterproof layer 52. This wear-resistant layer can improve the wear resistance and impact resistance of the floor.

[0039] Example 2:

[0040] Please see Figure 5Based on Example 1, a heat insulation layer 6 is provided between the moisture-proof layer 2 and the micro-resistance layer 3 to reduce heat transfer, improve indoor comfort, and extend the building's service life; an anti-corrosion surface layer 7 is provided between the surface layer 5 and the prestressed concrete layer 4 to protect the floor from corrosion. The heat insulation layer 6 is made of polystyrene foam board or rock wool board. The anti-corrosion surface layer 7 is coated with epoxy floor paint.

[0041] The construction method of the above embodiment 2 is as follows:

[0042] Clean and level the ground base layer 1. Apply an acrylic primer layer to the surface of base layer 1 to enhance the adhesion between base layer 1 and moisture-proof layer 2. Lay a moisture-proof film to form an effective moisture barrier. Lay a heat insulation layer 6, using materials such as polystyrene foam board or rock wool board. Install support components 41 and prestressed steel mesh 42, and pour concrete 43 to form a prestressed concrete layer 4. Apply an anti-corrosion material to the surface of the prestressed concrete layer 4 to form an anti-corrosion surface layer 7. Lay a waterproof layer 52, ensuring its integrity and sealing. Finally, lay a diamond abrasion wear-resistant layer 51 and anti-slip particles to form a large-area seamless floor structure.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and these all fall within the protection scope of the present invention.
