The utility model aims at providing a coiled material for the runway, which has good impact absorption capability.
Description
Technical field
The utility model relates to the athletic ground runway and uses the coiled material field, relates in particular to a kind of runway coiled material with good absorption impact capacity.
Background technology
Runway is important sports facility, in order to guarantee athletic sports achievement and to ensure athletic safety, the runway coiled material need possess beyond the certain rigidity, need better elastic, the more important thing is, the runway coiled material also needs to possess the excellent absorption impact capacity, like this to ensureing that athletic safety plays a big part.
But present runway coiled material does not also have such premium properties, and the existing runway that laying is obtained does not possess such premium properties yet.Existing runway contains bottom and the surface layer that is arranged on the ground, and wherein bottom is made up of with the elastic granule of curable cementing agent the surface, and the surface of surface layer has anti-skidding salient point, and has the space between anti-skidding salient point and the elastic granule.The purpose of this runway is to improve the elasticity of plastic cement race track, but there is the problem of two aspects in it, its structure slightly complicated of one side, on the other hand, this runway only has better elastic, but a little less than the absorptive capacity from the impact force that imposes on runway on top, this impact force feeds back to the user again, causes athletic injury easily.
The utility model content
The purpose of this utility model provides a kind of runway coiled material, has the ability that good absorption is impacted.
To achieve these goals, the technical solution of the utility model is:
A kind of runway coiled material, comprise: wear-resistant coat and elasticity bottom, the upper surface of the soffit of described wear-resistant coat and described elasticity bottom is bonding, and the soffit of described elasticity bottom is provided with elastic bar and Elastic Contact bar, and described elastic bar and described Elastic Contact bar intersect.
Alternatively, the upper surface of described wear-resistant coat is provided with asperities.
Preferably, described elastic bar is vertical with described Elastic Contact bar.
Alternatively, described Elastic Contact bar is provided with elastic contact head, and the angle of described elastic contact head and horizontal plane is less than 180 °.
Preferably, the angle of described elastic contact head and horizontal plane is 60 °.
Alternatively, the cross section of described elastic contact head is drops.
Alternatively, described elasticity bottom is the microporous foam layer.
Alternatively, the thickness of described wear-resistant coat is 4mm.
Alternatively, the thickness of described elasticity bottom is 9mm.
Therefore, compared with prior art, use the technical scheme of the utility model embodiment, following beneficial effect is arranged:
Runway coiled material of the present utility model is bonded into by wear-resistant coat and elasticity bottom, the soffit of elasticity bottom is provided with elastic bar and Elastic Contact bar, elastic bar and Elastic Contact bar intersect, the intersection geometry design that the runway coiled material is such, make the coiled material stress equalization, there is certain cushion space after making the elasticity bottom and ground contacting, make the runway coiled material have the ability that good absorption is impacted, after tested, the utility model runway coiled material impact absorption rate reaches 39%, surpasses the standard-required of the minimum impact absorption rate 35% of International Field Athletic Federation;
The Elastic Contact bar be provided with horizontal by elastic contact head less than 180 ° of angles, the inclined design of elastic contact head has strengthened the runway coiled material and has absorbed the ability of impacting, in addition, intersecting of the elastic bar of elasticity bottom and Elastic Contact bar, make between elasticity bottom and the basis, ground and formed drainage channel, also be beneficial to the discharge of ponding with guidance type.
The asperities that wear-resistant coat has makes it have higher wear-resisting toughness; The geometry designs that elastic bar is vertical with the Elastic Contact bar can be brought into play the runway coiled material to the full extent and absorb the ability of impacting; The Cross section Design of elastic contact head is a drops, makes the elasticity bottom of runway coiled material be unlikely to complete closed, has further improved the ability of impacting that absorbs to a certain extent.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
A kind of perspective view that Fig. 1 provides for the utility model embodiment with runway coiled material of good absorption impact capacity;
A kind of elevation that Fig. 2 provides for the utility model embodiment with runway coiled material of good absorption impact capacity;
