Description
Technical field
The utility model relates to the athletic ground runway and uses the material field, relates in particular to a kind of runway coiled material.
Background technology
Runway is important sports facility, is laid by the runway coiled material.The shortcoming of existing runway coiled material is, the runway coiled material has upper surface and soffit to be bonded into, edge after bonding is smooth, the problem that contact area is little, the goodness of fit is not high and joint strength is not enough of the interface between coiled material and the coiled material appears in the runway after make laying, and very easily ftractures after causing runway stressed, projection.
In addition, in order to guarantee athletic sports achievement and ensure athletic safety that the runway coiled material need possess beyond the certain rigidity, needs better elastic, 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, makes that the runway of being laid by this runway coiled material can not ftracture, projection.
To achieve these goals, the technical solution of the utility model is:
A kind of runway coiled material comprises: wear-resistant coat and elasticity bottom, and the upper surface of the soffit of described wear-resistant coat and described elasticity bottom is bonding, and the edge after the upper surface of the soffit of described wear-resistant coat and described elasticity bottom is bonding is step-like.
Alternatively, the upper surface of described wear-resistant coat is provided with asperities.
Alternatively, 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.
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 °.
Preferably, 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 5mm.
Alternatively, the thickness of described elasticity bottom is 8mm.
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, make the edge after bonding be step-like, the Interface design of this step overlap joint of runway coiled material improves the increase of interface contact area, the goodness of fit between coiled material and the coiled material, increased the intensity of interface, made the stressed back of runway after the laying not have cracking, no projection;
The asperities that wear-resistant coat has makes it have higher wear-resisting toughness; The soffit of elasticity bottom is provided with elastic bar and Elastic Contact bar, and elastic bar and Elastic Contact bar intersect, such intersection geometry design, stress equalization; The elastic contact head that the Elastic Contact bar is provided with, elastic contact head is horizontal by the α angle, the inclined design of elastic contact head cooperates the design of intersection geometry, has certain cushion space after making the elasticity bottom and ground contacting, and makes the runway coiled material have the ability that good absorption is impacted.After tested, the impact absorption rate of the utility model runway coiled material reaches 39%, surpasses the standard-required of the minimum impact absorption rate 35% of International Field Athletic Federation;
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.
