Description

Technical Field

[0001] The utility model relates to the relevant field of environmentally friendly EPDM granular courts, in particular to an environmentally friendly EPDM granular court. Background Art

[0002] EPDM courts are courts made of EPDM material laid on asphalt or cement foundation. EPDM material is widely used because of its rich colors, UV resistance, stable color, and will not fade even under the scorching sun. EPDM plastic courts use EPDM particles mixed with polyurethane glue, which is not only a fusion of technology, but also an interpretation of the best ground system for sports ground. This is the latest material for sports ground layers recognized by the "IAAF".

[0003] The existing device has the following shortcomings when in use: after the environmentally friendly EPDM granular court has been used for a long time, when the worn surface needs to be maintained and repaired, the EPDM court surface generally has a large installation module on the entire surface, which makes it inconvenient to carry out targeted repair and replacement of the worn parts, and it is inconvenient to repair the environmentally friendly EPDM granular court and the maintenance cost is high. Utility Model Content

[0004] The purpose of the utility model is to provide an environmentally friendly EPDM granular court to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an environmentally friendly EPDM particle court, comprising a soil layer, a water-absorbing layer, a mounting plate, a fixed plug rod, an EPDM particle board, and a fixed through hole. The top surface of the water-absorbing layer is paved with a mounting plate, and a plurality of EPDM particle boards are paved on the mounting plate. A limiting groove is provided on the mounting plate, and a limiting column is installed on the bottom surface of the EPDM particle board, and the limiting column is matched with the limiting groove. A connecting block is installed on the EPDM particle board, and a connecting groove is provided on the EPDM particle board, and the connecting block is matched with the connecting groove. A fixed socket is provided on the mounting plate, and a fixed through hole is provided on the limiting column. The fixed plug rod is inserted into the fixed socket and passes through the fixed through hole, so as to connect a plurality of EPDM particles. The M particle board is laid on the mounting plate, so that the limit column installed on the bottom surface of the EPDM particle board is inserted into the limit groove opened on the mounting plate, and the adjacent EPDM particle boards are fixedly connected by the connection block and the connection groove. After assembling multiple groups of EPDM particle boards, the fixed plug rod is inserted into the fixed socket opened on the mounting plate. The fixed plug rod will pass through the fixed through hole opened on the limit column, thereby fixing the EPDM particle board in the vertical direction. When the worn EPDM particle board needs to be maintained and repaired, the EPDM particle board to be replaced can be removed by pulling out the fixed socket. When the EPDM particle board is worn and needs to be repaired, it is convenient to carry out targeted maintenance and replacement of the worn parts, making the maintenance of the environmentally friendly EPDM particle court more convenient and reducing the maintenance cost.

[0006] In a further embodiment, the EPDM particle board is provided with a drain hole A, and the mounting plate is provided with a drain hole B. The number of the drain holes A and the drain holes B are the same and the hole positions in the vertical direction are aligned. Water flows to the water absorption layer through the drain holes A on the EPDM particle board and the drain holes B on the mounting plate. The water penetrates from the water absorption layer to the cement layer and then penetrates into the soil layer through the gravel layer, thereby preventing water accumulation on the pavement of the EPDM particle court from affecting normal use.

[0007] In a further embodiment, the fixed socket passes through the mounting plate on the left and right and is connected to the limiting groove. The aperture of the fixed through hole is the same as the aperture of the fixed socket. The fixed socket passes through the entire mounting plate on the left and right and passes through the limiting groove. In this way, when the fixed plug rod passes through the limiting groove, it will also pass through the fixed through holes opened on the multiple limiting columns in sequence to fix the multiple groups of EPDM particle boards in the vertical direction.

[0008] In a further embodiment, a waterproof layer is provided on the top surface of the EPDM particle board, and a marking paint layer is provided on the waterproof layer. The waterproof layer provided on the top surface of the EPDM particle board will prevent water from being adsorbed on the surface of the EPDM particle board during precipitation.

[0009] In a further embodiment, a gravel layer is laid on the top surface of the soil layer, a cement layer is laid on the top surface of the gravel layer, and a water-absorbing layer is laid on the top surface of the cement layer, so that water penetrates from the water-absorbing layer to the cement layer and then penetrates into the soil layer through the gravel layer.
