Description

Technical Field

[0001] This utility model relates to the field of polyurethane flooring technology, specifically to a full matte polyurethane flooring. Background Technology

[0002] In the past, epoxy resin flooring was often used for the flooring of underground parking garages. However, due to the many disadvantages of epoxy resin flooring, such as containing volatile organic compounds, high requirements for the construction environment, long construction period, easy cracking, blistering, poor weather resistance, and poor temperature difference resistance, polyurethane flooring has been gradually adopted.

[0003] Utility model CN219365289U discloses a wear-resistant polyurethane flooring structure suitable for underground parking garages, comprising, from bottom to top, a base layer, a polyurethane mortar base layer, a polyurethane mortar intermediate layer, a black corundum sandblasted layer, and a polyurethane topcoat layer; the base layer has crisscrossing anchoring grooves with a V-shaped cross-sectional profile. By setting the black corundum sandblasted layer on the polyurethane mortar intermediate layer, the anti-slip, wear-resistant, and impact-resistant properties of the polyurethane flooring are effectively enhanced, preventing vehicles from slipping when climbing slopes in underground parking garages and avoiding premature and rapid severe wear due to frequent friction from vehicle tires; the crisscrossing anchoring grooves increase the bonding stability between the polyurethane mortar base layer and the base layer, making it less likely for the polyurethane mortar base layer to detach from the base layer even with frequent vehicle friction.

[0004] However, the above-mentioned existing technologies still have shortcomings in use: the thickness of the polyurethane mortar layer is relatively small, and the floor will have local depressions after long-term rolling. The main reason for this is that the concrete base layer cracks, that is, the base layer lacks a reinforcing structure.

[0005] Therefore, this utility model provides a full matte polyurethane flooring. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a full matte polyurethane flooring to solve the problems mentioned in the background. This utility model improves the crack resistance of the concrete base layer by setting a reinforcement structure inside the concrete base layer, thereby effectively preventing the floor from sinking.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a matte polyurethane flooring, comprising a flooring body, wherein a polyurethane mortar coating and a concrete base layer are disposed within the flooring body, and a stabilizing structure is disposed within the concrete base layer, wherein a matte topcoat layer is disposed on the top of the flooring body, and the stabilizing structure comprises a matrix-arranged steel wire layer and a dot-matrix-arranged anchor pile, wherein the steel wire layer is tensioned and connected by the anchor pile, and a connecting sleeve is disposed on the top of the anchor pile, wherein a circumferentially uniformly distributed J-shaped groove is formed on the top of the connecting sleeve.

[0008] Furthermore, the anchor pile includes a positioning column and a pile column, the bottom of the positioning column and the pile column are detachably connected, and a positioning plate is welded to the bottom of the connecting sleeve, and a positioning hole for connecting the connecting sleeve is opened in the middle of the positioning plate.

[0009] Furthermore, the connecting sleeve and the positioning post are coaxially arranged, and the positioning disk and the positioning post are rotatably connected.

[0010] Furthermore, a lower stop plate located below the positioning disk and an upper stop plate located above the positioning disk are fixedly sleeved on the positioning post, and the positioning hole and the positioning post are fitted with a clearance fit.

[0011] Furthermore, the pile is a screw structure with a base plate welded to its bottom, and the bottom of the positioning column has a threaded hole that screws into the top of the pile. The bottom of the positioning column is fixedly fitted with an annular limiting plate.

[0012] Furthermore, the upper surface of the seat plate is welded with evenly distributed protrusions.

[0013] Furthermore, an external hexagonal drive head is welded to the top of the positioning post.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, by installing a stable structure in the concrete base layer, the stable structure includes anchor piles distributed in a dot matrix and steel wire layers distributed in a matrix. The anchor piles distributed in a dot matrix connect and tension the steel wire layers. After the concrete is poured, the tensioned steel wire layers can improve the crack resistance of the concrete base layer, thereby improving the durability of the ground.

[0016] 2. In this utility model, the anchor pile includes a connecting sleeve. The top of the connecting sleeve has a circumferentially evenly distributed J-shaped groove. When installing the steel wire layer, the warp and weft threads of the steel wire are passed through the J-shaped groove from above the connecting sleeve to limit and fix the steel wire. This structure has the advantage of making the installation of the steel wire layer more convenient and quick. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a full matte polyurethane floor, including a floor body 1, a polyurethane mortar coating 11 and a concrete base layer 12 located below the polyurethane mortar coating 11.

[0023] In this technical solution, a stabilizing structure 2 is provided within the concrete base layer 12. This stabilizing structure 2 improves the crack resistance of the concrete base layer 12 and also has the advantage of easy installation. The top of the floor body 1 is provided with a matte topcoat layer 3, which uses a common matte self-leveling antistatic epoxy topcoat, thereby eliminating reflections.

[0024] Specifically, the stabilizing structure 2 includes a matrix of steel wire layers 21 and a dot matrix of anchor piles 22. The steel wire layers 21 include warp wires and weft wires, which are arranged alternately to form the steel wire layers 21. The steel wire layers 21 are tensioned and connected by the anchor piles 22. In other words, the anchor piles 22 serve to support and fix the warp wires and weft wires.

[0025] Specifically, the top of the anchor pile 22 is provided with a connecting sleeve 221, and the top of the connecting sleeve 221 is provided with circumferentially evenly distributed J-shaped grooves 2211. When the warp wire and the weft wire pass through the two J-shaped grooves 2211 on the connecting sleeve 221, the anchor pile 22 can support and position the warp wire and the weft wire. The structural design of the J-shaped grooves 2211 makes the docking and separation operations of the J-shaped grooves 2211 and the connecting sleeve 221 more convenient.

[0026] Furthermore, the anchor pile 22 includes a positioning post 222 and a pile post 223. The bottom of the positioning post 222 and the pile post 223 are detachably connected. A positioning disc 2212 is welded to the bottom of the connecting sleeve 221. The positioning disc 2212 has a positioning hole in the middle that connects to the connecting sleeve 221. The top of the positioning post 222 extends upward out of the connecting sleeve 221. When the warp and weft wires are wound around the positioning post 222, the tension of the warp and weft wires can be further improved. The detachable design of the bottom of the positioning post 222 and the pile post 223 facilitates separate construction. That is, the pile post 223 is installed first, and then assembled with the positioning post 222 after the pile post 223 is fixedly installed.

[0027] Specifically, the pile 223 is a threaded rod structure with a base plate 2231 welded to its bottom. The bottom of the positioning column 222 has a threaded hole 2225 that screws into the top of the pile 223. The bottom of the positioning column 222 is fixedly fitted with an annular limiting plate 2223. In use, the pile 223 is first placed in the foundation trench, and then part of the concrete is poured, which buries the base plate 2231. After the concrete has cured, the positioning column 222 and the top of the pile 223 are screwed together. When tightened, the annular limiting plate 2223 will press against the upper surface of the concrete poured above, thereby ensuring that all connecting sleeves 221 are at the same height. The upper end face of the seat plate 2231 is welded with evenly distributed protrusions 22311. The protrusions 22311 can be short steel bars, the purpose of which is to improve the stability of the connection between the seat plate 2231 and the cured concrete. Then, the warp and weft wires are installed, and finally the remaining concrete is poured. At this time, the entire stable structure 2 is embedded in the concrete base layer 12.

[0028] In this embodiment, the connecting sleeve 221 and the positioning post 222 are coaxially arranged, and the positioning disk 2212 and the positioning post 222 are rotatably connected. This arrangement allows the warp and weft wires to be tensioned together when passing through the connecting sleeve 221. For example, when a warp wire passes through the current connecting sleeve 221, and a weft wire is installed on the connecting sleeve 221, it can be selected to pass through different J-shaped grooves 2211. When the weft wire is tensioned, it will drive the current connecting sleeve 221 to rotate by a certain amplitude. At this time, the connecting sleeve 221 can tension the warp wire passing through it. In specific implementation, a lower baffle 2221 located below the positioning disk 2212 and an upper baffle 2222 located above the positioning disk 2212 are fixedly sleeved on the positioning post 222. The positioning hole and the positioning post 222 are clearance-fitted. That is to say, the lower baffle 2221 and the positioning disk 2212 restrict the connecting sleeve 221 to the positioning post 222.

[0029] In this embodiment, an external hexagonal drive head 2224 is welded to the top of the positioning post 222. The external hexagonal drive head 2224 is a component that connects to the electric trigger head, making the screwing operation of the positioning post 222 more convenient.

[0030] Working principle: First, a foundation pit is excavated and leveled on the ground. Then, piles 223 are placed in the foundation pit in a dot matrix arrangement. A layer of concrete is then poured, which buries the protrusions 22311 while keeping the tops of the piles 223 exposed. After the concrete has cured, positioning posts 222 are installed on the top of each pile 223. Steel wires with a diameter of 0.2-1mm are used and passed through the connecting sleeves 221 at each dot matrix point in a cross-shaped arrangement. The warp and weft wires can be wound at right angles or in a straight line. After the warp and weft wires are formed, concrete is poured to bury the entire stable structure 2. After curing, a concrete base layer 12 is formed. A waterproof coating is applied to the concrete base layer 12. After the waterproof coating cures, a polyurethane mortar coating 11, a black corundum sandblasting layer, and a polyurethane topcoat layer are applied on top. The polyurethane mortar coating 11, the black corundum sandblasting layer, and the polyurethane topcoat layer all adopt the parameter structure mentioned in the background technology. Finally, a matte topcoat layer 3 is poured on top of the hardened polyurethane topcoat layer.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
