A special rubber plate for sports track

Abstract

The invention discloses a special rubber plate for a sports track, comprising a crushed stone layer, a heat dissipation layer is arranged on the crushed stone layer, a foam concrete layer is arranged on the heat dissipation layer, and a shock absorbing layer is arranged on the foam concrete layer , the shock-absorbing layer is provided with a waterproof layer, the waterproof layer is provided with a wear-resistant layer, and rubber particles are laid on the wear-resistant layer; a plurality of placement cavities are evenly opened in the wear-resistant layer, and the A plurality of shock-absorbing chambers are evenly opened in the shock-absorbing layer, and a shock-absorbing airbag is placed in each of the shock-absorbing chambers. An L-shaped exhaust pipe is installed on the upper end of the shock-absorbing airbag, and the L-shaped exhaust pipe The upper end extends into the placement cavity. The advantages are: the present invention has reasonable structure, good ventilation and heat dissipation, excellent drainage performance, good shock absorption and buffering effect, can increase the service life of the rubber plate and at the same time give athletes a certain boost, improve the athlete's sense of use, and has relatively stable physical properties. It is conducive to the performance of athletes' speed and technology.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a special rubber plate for sports tracks. Background technique [0002] Plastic track is an indispensable and important facility in modern track and field venues. Compared with traditional soil track, it has good elasticity, anti-skid, wear resistance, shock absorption, easy site maintenance, bright colors, beautiful and tidy, etc. In view of With the above advantages, the plastic track was quickly adopted by various track and field venues soon after it came out, and it has also been widely used in some universities and middle schools in recent years. [0003] However, the current existing plastic runway has poor drainage, and the runway is prone to water accumulation, which affects the normal use of the runway. At the same time, the air permeability of the plastic runway is not good. Under high temperature conditions, the steam generated by the foundation cannot be di...

Problems solved by technology

[0003] However, the current existing plastic runway has poor drainage, and the runway is prone to water accumulation, which affects the normal use of the runway. At the same time, the air permeability of the plastic runway is not good. Under high temperature conditions, the steam generated by the foundation cannot spread quickly, resulting in bubbling When the runway is under pressure, the air pressure will exert a certain pressure on the runway. The runway cannot effectively and quickly discharge the gas generated by the pressure. The long-term action of the gas will cause damage to the runway, which will greatly reduce the service life of the plastic runway.
