Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The following detailed description is provided for the specific embodiments of the present invention.

Please refer to fig. 1 to 5, the embodiment of the utility model provides a pair of polyurethane rubber runway shocks resistance of environment-friendly, polyurethane rubber runway shocks resistance of environment-friendly includes that asphalt concrete mixes lays the ground 1 that forms, and 1 upper berth of ground is equipped with polyurethane and lays layer 2, and polyurethane lays layer 2 by supreme plastic layer of laying on ground 1 and lay the limited slip layer on the plastic layer down, and polyurethane lays layer 2 and is sectional type mosaic structure, and all is connected with between arbitrary two sections polyurethane lays layer 2 and is fixed in the connecting piece 4 on the ground 1.

It should be noted that: in the runway, the polyurethane laying layers 2 belong to a multi-section splicing structure, and when any one section of the polyurethane laying layer 2 is damaged, any influence on other damaged polyurethane laying layers 2 cannot be generated, so that the damaged polyurethane laying layers 2 can be replaced in a targeted manner, and the cost of maintenance and replacement can be better controlled on the basis of ensuring complete treatment;

it should also be noted that: the connecting piece 4 is fixed on the foundation 1, so that the connecting piece has enough stability, and is connected to the end part position of the polyurethane laying layer 2, so that the end part of the polyurethane laying layer 2 is further limited, the position is not easy to generate edge warping, and the connecting piece has the advantages of the whole polyurethane laying layer 2, so that the possibility of damage in use is lower;

in the present embodiment: the upper end of the connecting element 4 can be coated with a layer of polyurethane material, so that the position can also have elasticity, and the sportsman can not be greatly hurt when falling down and contacting with the position.

In the embodiment of the present invention, referring to fig. 2 to 4, the two ends of any one section of polyurethane laying layer 2 are embedded with the integrated extension parts 3;

the connecting piece 4 comprises a bottom frame 41 which is fixed on the foundation 1 through bolts and is in a shape of Chinese character 'shan', a plurality of integrated and vertical positioning cylinders 42 are embedded on the upper end surface of the bottom frame 41, a top plate 43 is fixed on the upper end of the bottom frame 41 through bolts, inserting rods 44 corresponding to the positioning cylinders 42 in position and quantity are embedded on the lower end surface of the top plate 43, and the inserting rods 44 are matched with the positioning cylinders 42 in size;

wherein, the extension part 3 is located between the bottom frame 41 and the top plate 43, and the positioning tube 42 penetrates through the extension part 3.

It should be noted that: the extension part 3 and the polyurethane laying layer 2 belong to an integral structure and are fixed inside the connecting piece 4, so that the connecting piece 4 can limit the polyurethane laying layer so as to improve the stability of the polyurethane laying layer;

it should also be noted that: the underframe 41 and the top plate 43 in the connecting piece 4 are respectively positioned at the upper end and the lower end of the extension part 3, so that the extension part 3 can be clamped, and meanwhile, the positioning cylinder 42 on the underframe 41 also penetrates through the extension part 3, so that the connecting piece 4 has stronger limiting effect on the extension part 3 at the end part of the polyurethane laying layer 2, the connection between the two parts is more compact, and the service life is longer in subsequent use;
