Abstract
The utility model discloses a prefabricated runway coiled material, which comprises a wear-resisting layer and an elastic shock absorption layer, and the design keys are that the docking sides of the coiled material are provided with malposed docking edges. The docking sides of the prefabricated runway coiled material can be mutually staggered and docked, therefore, the coating area of adhesive is increased, the adhesion power on docking positions is strengthened, the depth of butt seams is reduced, the docking positions can be effectively prevented from heaving and warping, and bigger gaps are prevented from producing, thereby guaranteeing splicing runways to still keep excellent movement performance and longer service life in different temperature environment.
Description
Technical field
The utility model relates to the artificial course, specifically a kind of precasting runway coiled material of being made by rubber or plastic material.
Background technology
Mould (rubber) glue runway and claim round-the-clock motion runway again, make by base polyurethane prepolymer for use as, admixtured polyether, scrap tire rubber, EPDM rubber grain or PU particle, pigment, auxiliary agent, filler.Structure, materials according to its construction can be divided into: precasting plastic cement race track, full-plastic plastic cement race track, mixed type plastic track, compound plastic cement race track, vapor-permeable type plastic cement race track, EPDM plastic cement race track.Not environmental protection factor that mixed type plastic track exists in making installation and use and runway hardness and the homogeneity that coefficient of friction is wayward, the finished surface planeness is relatively poor, site operation is difficult to guarantee thickness, runway easily falls drawbacks such as grain, easily foaming, poor flexibility.The vapor-permeable type plastic cement race track can adopt mechanized construction technology, and speed of application is fast, and cost is lower, is widely used in the occasions to train, to impart knowledge to students such as middle and primary schools in recent years.But because a little less than this runway sport dynamics poor performance, anti-nail thorn and the anti-wear performance relative thin, so be not suitable for athletics place such as professional sports venue; The precasting plastic cement race track has good exercise performance and Environmental Safety, does not need to transport a large amount of materials and construction equipment when construction, also can not take large stretch of on-the-spot storage space.It provides comfortable, durable, healthy environment for use for the sportsman, thereby is subjected to the extensive favor in market deeply.
Pre-fabricated rubber running track is normally pieced together forming by 6～8 coiled materials, thereby its product is also referred to as precasting runway coiled material.The width of this coiled material is generally 1.22m～1.25m (promptly wide identical with a shunting).Coiled material is divided into upper and lower two-layer, and the upper strata is the wearing layer (adopting EPDM and natural rubber and artificial synthetic rubber) through special embossed, and lower floor is the elastic shock attenuation layer.When laying, only need be coated on the bottom surface of every coiled material, and then it is sticked on the basal plane get final product with special bonding adhesive.The weak point that this pre-fabricated rubber running track exists is the phenomenon that coiled material is acted upon by temperature changes easily and produces expansion or shrink.And the coiled material of this structure, its both sides are plumb cut, can only be that adjacent edge is flush when coiled material is spliced into runway with coiled material docks.Therefore, when coiled material expanded, drum can take place and stick up phenomenon in its joint; Otherwise when coiled material shrank, joint then produced bigger slit.Not only influence the exercise performance of runway thus, also influenced the application life of runway simultaneously.
The utility model content
The purpose of this utility model is exactly the precasting runway coiled material that a kind of new structure will be provided, to overcome the weak point of above-mentioned pre-fabricated rubber running track.
The purpose of this utility model is achieved in that
The precasting runway coiled material that the utility model is designed includes wearing layer, elastic shock attenuation layer, and its design main points are at coiled material edge fit to be provided with dislocation butt joint edge.
Like this precasting runway coiled material of design, when the splicing runway with corresponding dislocation butt joint along arrange in pairs or groups mutually, bonding together gets final product.Because the coiled material of this structure can interlacedly dock edge fit, therefore, has increased the spreading area of bonding adhesive, has strengthened the bonding force of joint, has reduced the degree of depth of butt joint, stick up and produces than slit greatly so can effectively stop joint that drum takes place.Thereby guaranteed that the splicing runway still can keep good exercise performance under the different temperatures environment, and long application life.

Fig. 3, Fig. 4 are the structural representations of the utility model specific embodiment.
The specific embodiment
As shown in Figure 1, the utility model includes wearing layer 1, elastic shock attenuation layer 3, coiled material edge fit is provided with dislocation butt joint along 2.Wearing layer 1 is the runway upper strata, and the optional usefulness of material has the ethylene propylene diene rubber (EPDM) of anti-weather, ageing-resistant, anti-ultraviolet property, and molding thickness can be controlled between 3-6mm; Elastic shock attenuation layer 3 is a runway lower floor, and material can be selected the natural rubber (NR) of excellent elasticity and the butadiene-styrene rubber (SBR) of ageing resistace excellence for use, and molding thickness can be controlled between the 7-10mm.For strengthening damping effect, the back side of elastic shock attenuation layer can be shaped on the honeycomb pit.The width of every coiled material is controlled at 1.23～1.30 meters (comprising the right side lines), can be spliced into wide through 8 coiled materials of dislocation butt joint is 9.76～10.00 meters track runway (eight shunting), and it is 7.32 meters to 7.50 meters (six shuntings) that 6 coiled materials can be spliced into wide.In splicing during runway, as shown in Figure 2, coiled material to the interlaced butt joint of edge fit.After the splicing, the runway integral thickness is smooth as one.On dislocation is docked along 2, be provided with convex tendon 4, on another relative dislocation is docked along 2, be provided with the groove 5 that is complementary with convex tendon 4.Like this time to the interlaced butt joint of edge fit, on one side the dislocation butt joint along in convex tendon 4 put in order in the groove 5 in the dislocation butt joint edge that can embed butt joint with it, further strengthened the butt joint dynamics thus.But convex tendon 4 its cross section semicirculars in shape (as shown in Figure 3) when concrete the making also can rectangular (as shown in Figure 4).
Claims (4)
1. a precasting runway coiled material includes wearing layer (1), elastic shock attenuation layer (3), and what it is characterized in that coiled material is provided with the dislocation butt joint along (2) to edge fit.
2. precasting runway coiled material according to claim 1 is characterized in that said dislocation butt joint is provided with convex tendon (4) along (2), is provided with the groove (5) that is complementary with convex tendon (4) on another relative dislocation butt joint edge (2).
3. precasting runway coiled material according to claim 2 is characterized in that its cross section semicircular in shape of said convex tendon (4).
4. precasting runway coiled material according to claim 2 is characterized in that its cross section of said convex tendon (4) is rectangular.
