Description

Technical Field

[0001] The utility model relates to the technical field of flooring, in particular to an anti-cracking wooden floor. Background Art

[0002] As we all know, wooden floor refers to a floor made of wood. The wooden floor produced in China is mainly divided into six categories: solid wooden floor, laminate wooden floor, solid wood composite floor, multi-layer composite floor, bamboo floor and cork floor. Moisture-proof is the most important task when laying wooden floor, and moisture-proof performance is also the most important technical indicator of wooden floor. If the moisture-proof work of the floor is not done well before laying, then in the subsequent use process, moisture will slowly penetrate into the wooden floor, causing the wooden floor to swell and then crack. After searching, patent authorization announcement No. CN 220226060 U discloses an anti-cracking wooden floor, including a floor body, a connecting groove is opened on one side of the floor body, and a connecting block is fixedly connected on the side of the bottom plate body away from the connecting groove. The connecting block and the connecting groove are adapted to each other, and a through hole is opened on the connecting block, which penetrates the floor body and is connected with the connecting groove. However, the above-mentioned wooden floor only sets a moisture-proof layer inside the wooden floor. In the actual laying process, it is necessary to leave a gap (expansion joint) between adjacent wooden floors. Moisture in the external air can easily enter the wooden floor through the gap, and then it is easy to make the wooden floor wet and crack. Utility Model Content

The upper moisture-proof isolation layer can block the moisture in the air above the wooden floor, and the lower moisture-proof isolation layer can block the moisture from the cement floor below the wooden floor. The desiccant can absorb the moisture entering from the gaps between adjacent wooden floors. In this way, the moisture-proof ability of the wooden floor can be improved, and the wooden floor can be prevented from absorbing a large amount of moisture during use and expanding to cause cracking.

[0012] 2. The utility model provides a convex head and a concave groove, and the upper and lower cooperation of the convex head and the concave groove can make the base layer and the decorative layer more firmly combined, and it is not easy to produce relative slippage, thereby making the various layers of the wooden floor more closely combined.

[0013] 3. The utility model provides a buffer layer and a flame retardant layer. The buffer layer is a foam layer, which can play a buffering role, making it more comfortable for people to step on it. The flame retardant layer is a flame retardant board, which can play a flame retardant role when a fire occurs, thereby reducing the risk of fire on the wooden floor.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 In the embodiment of the utility model, a crack-proof wooden floor comprises a base layer 1 and a decorative layer 6. A lower moisture-proof insulation layer 2 and an upper moisture-proof insulation layer 3 are respectively arranged at the lower and upper parts of the base layer 1. The lower moisture-proof insulation layer 2 and the upper moisture-proof insulation layer 3 are both moisture-proof films. A buffer layer 4 is arranged on the upper moisture-proof insulation layer 3. The buffer layer 4 is a foaming layer, which can play a buffering role, making it more comfortable for people to step on it. A flame-retardant layer 5 is arranged on the buffer layer 4. A decorative layer 6 is arranged on the flame-retardant layer 5. The decorative layer 6 is a wood grain decorative board. The flame-retardant layer 5 is a flame-retardant board, which can play a flame-retardant role when a fire occurs, reducing the risk of fire in the wooden floor. A wear-resistant layer 7 is arranged on the decorative layer 6. The wear-resistant layer 7 is an aluminum oxide wear-resistant layer, which has high hardness and wear resistance, and can effectively reduce the floor surface caused by friction. The base layer 1 is evenly provided with protrusions 10, which are matched with the grooves 11 evenly provided on the bottom surface of the decorative layer 6. The thickness ratio of the base layer 1, the buffer layer 4, the flame retardant layer 5 and the decorative layer 6 is 11:1:1:5. When installing the wooden floor, the lower moisture-proof isolation layer 2 and the upper moisture-proof isolation layer 3 are respectively pasted on the lower surface and the upper surface of the base layer 1, and then the base layer 1 is laid flat on the ground. Then, the buffer layer 4, the flame retardant layer 5, the decorative layer 6 and the wear-resistant layer 7 are laid on the base layer 1 in sequence. The layers are bonded by glue. The protrusions 10 evenly provided on the base layer 1 and the grooves 11 evenly provided on the bottom surface of the decorative layer 6 are matched one by one to make the connection of each layer more firmly. The adjacent wooden floors are plugged and matched with the plug-in part 8 and the slot part 9, and a certain gap is left in the middle for filling the gap with caulking agent.
