Detailed Description

Example 1

As shown in fig. 1 to 3, the present invention discloses a solvent-free polyurethane track, which is a polyurethane track and is certainly made of polyurethane, so the polyurethane layer 12 is disposed in the present embodiment, and can be used as the outer surface of the track for students and other people.

The runway usually comprises a plurality of lamellar structures, it is impossible to set up only one deck, especially for the polyurethane runway, because its top material is softer, if polyurethane layer 12 bottom direct contact soil, then polyurethane layer 12 receives when using power, just transmit to the soil very easily, just collapse after long-time use very easily, the wet degree of soil also can directly influence the use experience of runway simultaneously, so set up basic unit 1 in this embodiment, can separate polyurethane layer 12 and soil, support fixedly through basic unit 1 to the runway is whole.

In order to form a complete runway, the embodiment is further provided with a rubble layer 7, a cement layer 8, a lower adhesive layer 9 and an upper adhesive layer 11, the upper end and the lower end of the rubble layer 7 are respectively connected with the cement layer 8 and the base layer 1, the top of the cement layer 8 is connected with the lower adhesive layer 9, and the bottom of the polyurethane layer 12 is connected with the upper adhesive layer 11.

The biggest characteristic of the plastic track is that the plastic track has certain elasticity, and in order to strengthen the function, a plurality of buffer blocks 10 are arranged between the lower rubber layer 9 and the upper rubber layer 11 in the embodiment, so that the effect of buffering and shock absorption can be achieved, and meanwhile, the cross sections of the buffer blocks 10 are trapezoidal, so that the elasticity of the buffer blocks 10 can be more effectively exerted.

Although the rubble layer 7 can the diffusion stress, closely adjacent inadequately between the rubble, it is easy loose when receiving vibrations, in order to consolidate the rubble layer 7, has set up a plurality of bracing pieces 6 at basic unit 1 top in this embodiment, can prevent effectively that the rubble in the rubble layer 7 is not hard up.

Polyurethane runway is in the use, and its drainage function is also very important, and in order to avoid the rainwater to stay there being the inside use to crowds such as students of runway and cause the influence, set up outlet 2, drain 3, water inlet 4 on basic unit 1 in this embodiment, during rainwater infiltration basic unit 1 top, can get into drain 3 through water inlet 4, discharge through outlet 2 again at last.

In order to make the rainwater get into drain 3 more fast, set up the cross-section on basic unit 1 upper portion into triangle-shaped in this embodiment, can make the rainwater flow to water inlet 4 departments along its inclined plane fast, be favorable to the quick seepage of rainwater.

Because the water inlet 4 top is exactly the rubble layer 7, in order to avoid the rubble in the rubble layer 7 to pass through water inlet 4 entering water drainage 3, set up filter screen 5 in this embodiment, not only can block the rubble in the rubble layer 7, can also filter the water that flows into in the water drainage 3.

In order to make the base layer 1 more firm and durable, the material of the base layer is asphalt concrete, so that the base layer is compact, stable, appropriate in roughness and durable, and can effectively separate soil from other layered structures;

in order to avoid wasting resources by making the base layer 1 too thick or easily breaking by making it too thin, the thickness is set to 75mm in this embodiment.

In order to make the filter screen 5 more durable, select its material for use in this embodiment to be metal rubber, be applicable to environment such as high low temperature, big difference in temperature, high pressure, high vacuum, strong radiation, violent vibration and corruption, simultaneously corrosion-resistant, intensity is big, shock resistance.

In order to strengthen the rubble in the rubble layer 7 better, dislocation set about adjacent bracing piece 6 in this embodiment, can more effectual reinforcement rubble layer 7 to prevent that the rubble in the rubble layer 7 from removing at will.

In order to prevent the crushed stones in the crushed stone layer 7 from entering the water drain 3 through the water inlet 4, the sizes of the crushed stones in the crushed stone layer 7 are all larger than the sizes of the meshes in the filter screen 5 in the embodiment.

In order to use the runway better, set up runway micelle and white PU lacquer marking off at polyurethane layer 12 top in this embodiment, runway micelle compressive strength is high, and hardness elasticity is moderate, and physical properties is stable, can increase frictional force simultaneously, can effectively reduce the rate of slipping and falling injury, and white PU lacquer marking off is safer environmental protection, durable more, simultaneously more striking.

In order to make the interior rainwater of runway discharge more fast, set up the hole 13 of permeating water of a plurality of vertical settings in buffer block 10 in this embodiment, make water such as rainwater pass through polyurethane layer 12, go up the glue bed 11 and permeate this layer after, can more fast smoothly continue downward flow infiltration, prevent that the rainwater from gathering unable discharge in the runway.

The utility model discloses a theory of operation: in the laying process, from up laying basic unit 1 down in proper order, metalling 7, cement layer 8, glue film 9 down, buffer block 10, go up glue film 11, polyurethane layer 12, set up permeable hole 13 in buffer block 10, make hydroenergy in the runway permeate down fast enough, a plurality of bracing pieces 6 have been set up between basic unit 1 and cement layer 8, can consolidate metalling 7, when rainwater permeates to basic unit 1 top, because 1 upper portion cross-section of basic unit is triangle-shaped, therefore the rainwater can flow to both sides, and in 4 entering water drainage channels 3 of water inlet, at last through outlet 2, filter screen 5 sets up in water inlet 4 department, not only can prevent that the rubble in the metalling 7 from falling to water drainage channels 3, can also filter the water through 4 departments of water inlet.

The mechanical connection according to the present invention is a conventional means used by those skilled in the art, and can be suggested by limited tests, which is common knowledge.

Components not described in detail herein are prior art.

Although the present invention has been described in detail with reference to the specific embodiments, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge range of those skilled in the art, and modifications or variations without creative efforts are still within the scope of the present invention.
