A floor structure of an indoor gymnasium

Abstract

The invention discloses a floor structure of an indoor stadium. The floor structure comprises an upper stone-plastic floor layer and a lower vibration-reducing floor layer, wherein the stone-plastic floor layer comprises floor sheets, and the vibration-reducing floor layer comprises projecting sheets. Each projecting sheet comprises warping portions and a pressure-bearing portion, each pressure-bearing portion supports the corresponding floor sheet, a friction block is arranged between each two adjacent projecting sheets, and the warping portions of the projecting sheets contact with the corresponding friction blocks. Compared with the prior art, the floor structure of the indoor stadium has the advantages that when under pressure from the corresponding floor sheets, the pressure-bearing portions can drive the warping portions on two sides thereof to ascend to contact with the friction blocks according to the lever principle, the larger the ascent amplitude is, the higher friction block squeezing force is, and accordingly braking is achieved, a space is reserved for each floor sheet to descend and buffer, and the whole floor structure can have good elasticity to protect leg joints of athletes.

Description

technical field [0001] The invention relates to a floor structure, in particular to a floor structure of an indoor gymnasium. Background technique [0002] With the improvement of the education system, indoor sports fields have been built in major schools to facilitate physical exercise on rainy days. However, most of the existing floors are made of a single material and are relatively hard. Students exercise on the floor for a long time. Finally, it will cause damage to the leg joints. Generally, low-density foam materials must be used to solve the shock-absorbing problem. However, due to the relatively high compression rate of low-density foam materials, it is easy to cause uneven floor thickness and depression after long-term trampling. And then affect the use of the product. How to ensure the service life of the product while improving the shock absorption performance is impossible for products with a single structure or material. [0003] For example, the patent No. 2...

AI Technical Summary

Problems solved by technology

This method has recognized the use situation of the floor in gymnasiums by limiting the deformation of the above-mentioned cushion member by contacting the above-mentioned floor with the peak of the above-mentioned fixed plate when the compressive deformation of the above-mentioned cushion member reaches a predetermined amount when the load is applied to the above-mentioned floor joist. The problems of frequent floor use, dense stepping points, and heavy stress have improved the floor connection structure, but this method provides a solution for how a single floor is deformed under force, and does not give a solution for the splicing points between floors. Deformation solution, therefore, this method will damage the floor joint and its service life is not guaranteed
