AI Technical Summary

Technical Problem

Wooden floors are prone to soaking and expanding when exposed to water, which in turn causes deformation between the paved wooden floors. The waterproof coating effect of existing moisture-proof methods weakens with the use time.

Method used

A three-layer floor core layer with equal joints is designed, including the upper layer, the middle layer and the lower layer. The middle layer is a mezzanine, which contains a sliding plate and an elastically deformable anti-swelling piece. The two sides of the sliding plate are fixedly connected to the sliding blocks. Sliding grooves are opened near the end surfaces of the upper and lower layers. The sliding blocks extend into the sliding grooves to form anti-swelling grooves and fill the anti-swelling parts, increasing the surface area of ​​the floor body to reserve expansion space.

Benefits of technology

The anti-swelling parts are isolated from the moisture in the air, reducing the water absorption and expansion of the sliding plate, and the installation of sliding grooves and sliding blocks reserves expansion space, reducing the extrusion deformation caused by water absorption and expansion, and improving the moisture-proof and anti-deforming effect of the floor.

[0003] Due to the material problem of wooden floors, the moisture-proof effect of wooden floors is not as good as that of ceramic tiles. They easily expand when exposed to water, which causes the laid wooden floors to squeeze each other and deform. Most moisture-proof methods are to apply a waterproof coating on the surface of the wooden floor to make it waterproof, but as the use time increases, the effect of the waterproof coating will weaken.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0018] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] A three-layer floor core layer with equal seam anti-deformation, such as Figure 1 , Figure 3 and Figure 4As shown, the floor body includes an upper layer 1, a middle layer 2 and a lower layer 3. The middle layer 2 is located between the upper layer 1 and the lower layer 3 as a sandwich. The middle layer 2 is composed of a plurality of sliding plates 4. An elastically deformable anti-expansion member 5 is arranged between the sliding plates 4. A plurality of sliding blocks 6 are fixedly connected to the end surfaces of both sides of the sliding plates 4. A plurality of sliding grooves 7 are provided on the end surfaces of the upper layer 1 and the lower layer 3 close to the middle layer 2. The sliding blocks 6 extend into the sliding grooves 7. The anti-expansion member 5 is provided to prevent moisture. The material of the anti-expansion member 5 is set to foam plastic. The foam plastic has the characteristics of closed cells and non-water absorption, so as to achieve a moisture-proof effect and reduce the expansion caused by the sliding plate 4 absorbing water. Compared with the hollow structure, this structure can increase the structural strength. The setting of the sliding grooves 7 and the sliding blocks 6 is to reserve space for expansion by increasing the contact area between the floor body and the outside world, thereby reducing deformation caused by extrusion due to water absorption and expansion.

[0020] like Figure 1-Figure 3 As shown, when the upper layer 1, the middle layer 2 and the lower layer 3 are combined together, a crack is formed between the sliding plates 4, and the crack is located in the interlayer between the upper layer 1 and the lower layer 3, forming an anti-expansion groove 8 with the upper layer 1 and the lower layer 3, and filling the anti-expansion groove 8 with elastic anti-expansion parts 5. The setting of the anti-expansion groove 8 reserves a certain space to accommodate the expansion of the floor body. Since the expansion distance of wood fiber is between millimeters, the width of the anti-expansion groove 8 is set to one centimeter, and the cross-section of the anti-expansion groove 8 is set to a lightning shape. During assembly, the lightning-shaped cross-section has many more turns than the vertical cross-section, so that the sliding plate 4 is not easy to fall off. The lightning-shaped anti-expansion groove 8 can strengthen the floor body and increase the contact area between the wood fiber and the outside world compared to the vertical shape, thereby increasing the expansion space and further reducing the deformation caused by the squeezing between the wood fibers caused by the expansion.

[0021] like Figure 1-Figure 4 As shown, anti-expansion through holes 9 are evenly opened on the side walls of the upper layer 1 and the lower layer 3. The anti-expansion through holes 9 are used for ventilation to keep the floor body dry and reduce deformation caused by water absorption and subsequent expansion due to moisture. The cross-sections of the sliding groove 7 and the sliding block 6 are both square. The center point of the cross-section of the sliding block 6 is coaxially arranged with the center point of the cross-section of the sliding groove 7. The sliding block 6 extends into the sliding groove 7. The outer wall of the sliding block 6 does not contact the inner wall of the sliding groove 7, so that there is space for expansion between the sliding block 6 and the sliding groove 7, and the expansion can be more uniform. A stabilizing member 10 is arranged in this space. The stabilizing member 10 is a cut foam plastic and completely fits the outer wall of the sliding block 6 and the inner wall of the sliding groove 7. When the middle layer 2 is spliced ​​and combined with the upper layer 1 and the lower layer 3, the stabilizing member 10 can make the structure more solid and enhance the stability of the structure.

[0022] Working principle: The floor body is glued together by the upper layer 1, the middle layer 2 and the lower layer 3. A fixing strip 11 is fixed on one side wall of the upper layer 1 and the lower layer 3. The adjacent fixing strips 11 form a limiting groove on the side wall of the floor body. A fixing strip 2 12 is fixed on the end surface of the middle layer 2 away from the fixing strip 11. When the two floor bodies are spliced, the fixing strip 2 12 extends into the limiting groove. This splicing method has the characteristics of making the structure more compact and stable and making the object more beautiful. After the floor bodies are spliced, since an anti-expansion groove 8 is formed between the upper layer 1 and the lower layer 3, the anti-expansion piece 5 is cut into the same shape as the anti-expansion groove 8. The anti-expansion groove 8 is filled, and both the upper layer 1 and the lower layer 3 are provided with anti-expansion through holes 9. In addition, the setting of the sliding groove 7 increases the contact area between the floor body and the outside world and reserves a certain expansion space to achieve the purpose of reducing the extrusion caused by expansion and thus reducing deformation. The anti-expansion through holes 9 also have the effect of ventilation to keep the floor body dry, thereby reducing deformation due to water absorption and expansion. The setting of the anti-expansion groove 8 with a lightning-shaped cross-section can make the spliced ​​combination more firm. The sliding block 6 is centrally placed in the sliding groove 7, which can make the expansion of wood fibers more evenly distributed in the sliding groove 7, thereby reducing deformation.

[0023] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
