Description

A kind of high-elastic environmentally friendly runway particle

Technical field

Plastic cement race track field is the utility model is related to, is specially a kind of high-elastic environmentally friendly runway particle.

Background technology

Plastic cement race track is also known as round-the-clock athletics tracks, by base polyurethane prepolymer for use as, admixtured polyether, scrap tire rubber, EPDM rubber grain or PU particles, pigment, auxiliary agent, filler composition.Plastic cement race track is with flatness is good, compression strength is high, hardness bullet Property the appropriate, characteristic of stable physical property, be conducive to the performance of sportsman's speed and technology, effectively improve sports achievement, drop Low tumble injury rate.Plastic cement race track is made of materials such as polyurethane rubbers, has certain elasticity and color, has certain resist UV resistance and ageing-resistant power are optimal all-weather outdoor athletic ground terrace materials generally acknowledged in the world.Existing plastic cement race track Laying project usually builds the smooth steel and concrete structure in Jianping on ground, since steel and concrete structure is harder, be Protection of the sportsman body joints, Ligament equivalent damage, it usually needs be laid with very thick plastic layer, like this increase cost, and plastic layer is due to being uniformly to be subject to Gravitational thrusts load, therefore easily shear stress occur in stress surface edge, cause it is cracked, and more frequencys by Local temperature raises after power, bulge phenomenon occurs.

Utility model content

In view of the above problems, the utility model provides a kind of high-elastic environmentally friendly runway particle, increase helps bullet device, easy to carry High resiliency, reduces cost, and while wire bundle improves intensity, is convenient for heat conduction and heat radiation, improves service life, can be with Effectively solve the problems, such as in background technology.

To achieve the above object, the utility model provides following technical solution：A kind of high-elastic environmentally friendly runway particle, including Grain body, move towards set with including supple buffer layer and hard by bed course, supple buffer layer inside depth for the particle bulk There is multigroup wire bundle, the upper surface of the supple buffer layer with being located at hard bed course, the hard ground upper surface of bed course etc. It is arranged at intervals with T-shaped groove, the position that the lower surface of the supple buffer layer corresponds to T-shaped groove is provided with convex block, the flexibility Cushion is rabbeted in T-shaped groove with being fixedly connected on hard on bed course by convex block, the supple buffer layer and hard ground cushion Inner groovy is provided between two groups of adjacent convex blocks on the contact surface of layer, the inner groovy, which is internally provided with, helps bullet device.

As a kind of preferable technical solution of the utility model, the wire bundle spacing inside the supple buffer layer 30mm-50mm, and arranged in length and breadth in interlocking.

It is described to help bullet device to include cushion block and spring, the spring as a kind of preferable technical solution of the utility model At inner groovy inside top surface, and cushion block is located inside inner groovy, and upper-end contact cushion block, lower end in contact hard ground bed course Upper surface.

As a kind of preferable technical solution of the utility model, the upper surface of the supple buffer layer is coated with protection and applies Layer, scribbles glue between the contact surface of bed course the supple buffer layer and hard.

Compared with prior art, the beneficial effects of the utility model are：Bullet device is helped by increase, easy to improve elasticity, Lower the thickness of plastic layer, reduce cost, be beneficial to Protection of the sportsman health, and wire bundle improves the same of intensity When, heat conduction and heat radiation is convenient for, improves service life.

Embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained, shall fall within the protection scope of the present invention.

Embodiment：

Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of high-elastic environmentally friendly runway particle, including particle sheet Body 1, move towards set with including supple buffer layer 2 and hard by bed course 3, the 2 inside depth of supple buffer layer for the particle bulk 1 Have multigroup wire bundle 5, the upper surface of the supple buffer layer 2 with being located at hard bed course 3, the hard bed course 3 upper table Face is equidistantly provided with T-shaped groove 6, and the position that the lower surface of the supple buffer layer 2 corresponds to T-shaped groove 6 is provided with convex block 7, The supple buffer layer 2 is rabbeted in T-shaped groove 6 with being fixedly connected on hard on bed course 3 by convex block 7, the flexible buffer Layer 2 is provided with inner groovy 8 with hard between two groups of adjacent convex blocks 7 on the contact surface of bed course 3, in the inner groovy 8 Portion sets and helps bullet device.

In the present embodiment, the 5 spacing 30mm-50mm of wire bundle inside the supple buffer layer 2, and in the cloth in length and breadth that interlocks Put, multi-tier arrangement increases shear strength when receiving shear stress, avoids the occurrence of crackle, described to help bullet device to include cushion block 9 With spring 10, the spring 10 is located at 8 inside top surface of inner groovy, and cushion block 9 is located inside inner groovy 8, and upper-end contact pad Block 9, lower end in contact hard bed course 3 upper surface, the upper surface of the supple buffer layer 2 is coated with protective coating 4, increases table Glue is scribbled between the contact surface of bed course 3 face wearability, the supple buffer layer 2 and hard, increases stable connection.

The operation principle of the utility model：When runway surface is subject to shock loading, supple buffer layer 2 compresses energy-absorbing, and And help the spring played in device also to absorb part energy, and the impact injury of supple buffer layer 3 is reduced, when load eliminates, Help and play device reset, auxiliary flexible cushion is sprung back, and easy to improve elasticity, is lowered the thickness of plastic layer, is reduced cost, have Beneficial to Protection of the sportsman health；During the downward Shear flexibility cushion 3 of shock loading, wire bundle 5 improves shear strength, Phenomenon of rupture is avoided the occurrence of, while local heating is carried out heat conduction and heat radiation by wire bundle 5, avoids the occurrence of bulge phenomenon, raising makes Use the service life.
