Abstract
The utility model discloses a waterborne environmental protection plastic course, including bottom, basic unit and top layer, the upper surface of basic unit is equipped with a plurality of recesses that transversely just link up the setting along the runway, the lower surface on top layer be equipped with with the sand grip of groove phase adaptation, the sand grip with the recess is pegged graft. Its joint strength who has strengthened between top layer and the basic unit has prolonged plastic course's life.
Description
Technical field
This utility model relates to sports articles for use technical field, particularly to a kind of aqueous, environmental protective plastic cement race track.
Background technology
Plastic cement race track, also known as round-the-clock athletics tracks, is indispensable critical facility in modern track and field place.Compared with traditional soil property runway, it has good elasticity, skid resistance, wearability, shock absorption, and place nursing is easily, in bright gay color, the advantage such as neatly attractive in appearance.In view of above-mentioned advantage, plastic cement race track comes out and is used by each Track field the most rapidly, and some universities, middle school are also widely used in recent years.
Existing Authorization Notice No. is that the Chinese patent (documents 1) of CN201738213U discloses a kind of plastic cement race track, and it includes laying bottom, basic unit and the top layer being molded as one successively, and described bottom is laid by black rubber granule and formed；Basic unit is arranged on bottom upper surface, is to be laid by ethylene propylene diene rubber granule to form；Described top layer is the EPDM glue granular layer being sprayed on basic unit's upper surface.It is bonded together by intermolecular force between basic unit and the top layer of plastic cement race track, during using, top layer is by active force backward, basic unit provides active force forward to make top layer reach stress balance for top layer, when top layer is by bigger rearward force, basic unit's deficiency thinks that top layer provides enough forward force, now top layer by force unbalance, top layer will depart from basic unit, and then reduces the service life of plastic cement race track.
Utility model content
The purpose of this utility model is to provide a kind of aqueous, environmental protective plastic cement race track, which increases the bonding strength between top layer and basic unit, extends the service life of plastic cement race track.
Above-mentioned technical purpose of the present utility model has the technical scheme that
A kind of aqueous, environmental protective plastic cement race track, including bottom, basic unit and top layer, it is characterized in that: the upper surface of described basic unit is provided with some grooves along runway horizontally set, the lower surface on described top layer is provided with the raised line suitable with described groove, described raised line and described groove grafting.
By using technique scheme, basic unit passes through groove together with raised line socket connection with top layer, increase basic unit and the bonding strength on top layer, when top layer is subject to bigger rearward force, basic unit can be that top layer provides enough forward force to make top layer stress balance, and then extends service life of the present utility model.
This utility model is further arranged to: the cross section of described groove is that rectangle is arranged.
By using technique scheme, the groove that rectangle is arranged, for arc, has preferable position-limiting action.
This utility model is further arranged to: some described grooves are for being placed equidistant.
By using technique scheme, groove is uniformly distributed in this utility model, makes the interaction force between top layer and basic unit evenly, is not result in the wrinkling of local or deformation.
This utility model is further arranged to: be provided with the water soluble acrylic acid glue-line for increasing both adhesive strengths between described basic unit and top layer.
By using technique scheme, prevent the top layer causing position herein owing to the colored particle contained in top layer touches basic unit do not bond with basic unit together with situation occur, further increase the adhesion strength of top layer and basic unit, and then extend service life of the present utility model.
In sum, this utility model has the advantages that the bonding strength which increasing between top layer and basic unit, extends the service life of plastic cement race track.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment；
Fig. 2 is the sectional view A-A of Fig. 1.
Reference: 1, bottom；2, basic unit；21, groove；3, water soluble acrylic acid glue-line；4, top layer；41, raised line.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Embodiment: aqueous, environmental protective plastic cement race track, as shown in Figure 1 to Figure 2, including bottom 1, basic unit 2 and top layer 4, basic unit 2 is provided with some grooves 21 along runway horizontally set, some grooves 21 are for being placed equidistant, and top layer 4 is provided with the raised line 41 suitable with groove 21, raised line 41 and groove 21 grafting.Basic unit 2 passes through groove 21 together with the socket connection of raised line 41 with top layer 4, increase basic unit 2 and the bonding strength on top layer 4, when top layer 4 is subject to bigger rearward force, basic unit 2 can be that top layer 4 provides enough forward force to make top layer 4 stress balance, and then extends service life of the present utility model.
The cross section of groove 21 can be that rectangle is arranged, arc is arranged, and the groove 21 that rectangle is arranged, for arc, has preferable position-limiting action.
Basic unit 2 is water soluble acrylic acid glue and rubber black granule composition, and the thickness of basic unit 2 is 9～11mm；Top layer 4 is water soluble acrylic acid glue and colored particle composition, and the thickness on top layer 4 is 3mm；The water soluble acrylic acid glue-line 3 for increasing both adhesive strengths it is provided with between basic unit 2 and top layer 4, the setting of water soluble acrylic acid glue-line 3 be possible to prevent the top layer 4 causing position herein owing to the colored particle contained in top layer 4 touches basic unit 2 do not have with basic unit 2 bonding together with situation occur, further increase top layer 4 and the adhesion strength of basic unit 2, and then extend service life of the present utility model, wherein, water soluble acrylic acid glue-line 3 is formed by Waterborne acrylate adhesive blade coating, Waterborne acrylate adhesive is disclosed at the Chinese patent that Authorization Notice No. is CN102533185B, therefore not to repeat here.Additionally, bottom 1 of the present utility model is set to bitumen layer or cement layer, the thickness of bottom 1 is 5～10mm.
This utility model is during construction, according to " track and field facility manual of standards " and related specifications standard, it is laid, wherein, basic unit 2 is after laying completes, surface press flute 21 in basic unit 2, water soluble acrylic acid glue-line 3 is uniformly scratched again, finally spraying top layer 4 levelling on the surface of basic unit 2.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
