Self-absorbing sports plastic floor capable of preventing temperature difference deformation after being assembled

Abstract

The invention provides a self-absorbing sports plastic floor capable of preventing temperature difference deformation after being assembled. The self-absorbing sports plastic floor is formed by fastening and assembling connecting rings 3 and connecting columns 4 which are arranged on the side walls of spliced plastic floor blocks and floor blocks in pairs, the connecting rings are arranged on two adjacent sides of the spliced plastic floor blocks, and the connecting columns are arranged on the other two adjacent sides of the spliced plastic floor blocks, and the walls of the connecting rings are each in a corrugated or zigzag shape. The innovative point is that deformed holes 1 are vertically and horizontally distributed in the floor blocks, and the deformed holes are composed of 3-6 hollow spiral lines 5 in a section mode, outwardly extending hollow parts of the adjacent two hollow spiral lines communicate with each other to form expansion space of temperature difference deformation, and floor block supporting columns 2 are disposed on the back surfaces of the central solid parts of the deformed holes. When the temperature difference deformation occurs, each hollow spiral segment performs deformation and absorption toward the middle, and since the slight deformation and absorption are symmetrical in four directions, the floor can still be kept flat without leaving floor joints to adjust the deformation amount.

Description

technical field [0001] The invention relates to a self-absorbing sports plastic floor that prevents deformation due to temperature difference after assembly. It is a replacement product of the current spliced ​​plastic floor, and is especially suitable for sports venues and public facilities. The plastic floor can be freely lapped and disassembled, and belongs to the assembled floor. technology field. Background technique [0002] Plastic flooring is a commonly used decorative material, which has the advantages of easy manufacture, various varieties, and low cost. In recent years, with the renewal of sports venues, assembled plastic flooring has become more and more popular. Therefore, people have improved the traditional plastic floor and proposed various overlapping plastic floors. The plastic floor is provided with locks, and two plastic floors are overlapped with each other through the locks on the plastic floor. This kind of floor can be laid directly on the ground, e...

AI Technical Summary

Problems solved by technology

However, there are problems in the use of assembled plastic flooring: due to the thermal expansion and contraction of plastic or plastic materials, the floor is deformed by temperature difference, and in severe cases, the floor in the venue is warped due to deformation, which directly affects the use function and life.

In order to solve the problem of temperature difference deformation, most of the existing technologies solve the problem by enlarging the seam, but if the seam is too large, it will easily make the floor loose and affect the use effect, and if the seam is too small, it cannot meet the temperature difference deformation requirements

More importantly, in the actual use process, the joints of the floor boards are often closed due to falling dust and sand, so that the floor's ability to resist deformation due to temperature differences is greatly reduced
