Double-layer composite plastic floor

Abstract

The invention discloses a double-layer composite plastic floor. The double-layer composite plastic floor comprises a floor surface layer and a floor cushion layer which is arranged under the floor surface layer, wherein the floor surface layer and the floor cushion layer are paralleled to each other and are horizontally and longitudinally connected together in a dislocation adhesion way, bulge parts between the floor surface layer and the floor cushion layer are formed into connecting strips and connecting lap strips, and adhesive sticker is coated on connecting surfaces opposite to the connecting strips and / or the connecting lap strips; and the floor cushion layer is formed by connecting a left floor cushion layer and a right floor cushion layer through connecting rabbets in a clamping way, the connecting rabbets are just arranged at long sides of the floor cushion layer and are formed by convex tenons and concave mortises, the convex tenons and the concave mortises are respectively arranged at long edges at two sides of the floor cushion layer and can form inserting connection, the convex tenons and the concave mortises are of parallelograms, and the convex tenons and the concave mortises are matched. According to the double-layer composite plastic floor disclosed by the invention, the inserting connection of the tenons and the mortises can be easily and quickly realized, and thus the assembly and the disassembly of a floor can be easy and efficient; and through an optimization structure, the manufacturing technology difficulty can be reduced, the manufacturing cost can be reduced, and the structural strength of a connecting tenon can be increased.

Description

technical field [0001] The invention relates to a plastic floor, in particular to a double-layer composite plastic floor. Background technique [0002] Plastic flooring has the characteristics of strong decoration, good foot feel, and lightness. People often choose plastic flooring to decorate indoor floors. The existing plastic floor is divided into two categories, one is a traditional plastic floor with smooth sides, and the other is a spliced ​​plastic floor with a locking structure around it. Traditional plastic flooring is widely used, but its disadvantages are also obvious: the construction requires high temperature, humidity and flatness of the ground, resulting in high construction costs; In addition, it is necessary to apply solvent glue on the ground before bonding, the construction progress is slow, and a professional construction team is required; in addition, a large amount of solvent glue is used, which is easy to seriously pollute the indoor air; due to the t...

Problems solved by technology

However, this type of plastic floor also has shortcomings: due to the tight fit of the locks at the clamping parts, it is more troublesome to assemble and disassemble the floor; lock structures must be provided on the long and short sides of the plastic floor, and in order to meet the needs of the floor According to the assembly requirements of the plastic floor, the locking structure on the long and short sides of the plastic floor needs to meet higher position accuracy requirements, which undoubtedly increases the manufacturing accuracy requirements and manufacturing costs; on the connecting tenon of the locking structure, the width of the root is the smallest. , the structural strength is poor, easy to damage, and affects the service life of the plastic floor; the spliced ​​plastic floor that is widely used now is made of the floor surface and the floor cushion, and the lock structure is set on the floor cushion. Due to the manufacturing process, the mutual position accuracy of the connecting tenons or connecting notches on the same side of the floor cushion is relatively easy to guarantee, but the relative position accuracy of the matching connecting notches and connecting tenons on both sides is difficult to guarantee, and the manufacturing error is relatively large. The technical floor cushion is a whole, and it is impossible to adjust the relative positions of the matching connection notch and tenon on both sides. It is difficult to meet the assembly requirements when assembling such a plastic floor
