Prefabricated Sport Court

The present invention relates to a plastic tile or floor covering supported on a floor surface to provide a sports arena surface such as basketball, tennis, futsal, etc., in particular both friction and safety imposed by sudden lateral forces during use. A plastic tile or floor covering that is engaged to form the required race surface.

In more detail, it is possible to maintain a continuous square lattice structure therein, and to form a joint including a vertex support leg and a corner support leg for distributing the load applied to the prefabricated sports court, and a cross coupling for inducing a coupling. A rectangular prefabricated sports court block and a rectangular outer frame portion, each of which has a continuous grid structure in one row, having a unit and a coupling part, and including a rectangular prefabricated sports coat block formed by including an X-shaped reinforcement rib formed inside the lattice structure. It relates to a prefabricated sports coat block of the shape.

Extensive floor coverings have been developed for use as athletic floors for sports activities. For example, hardwood floors are comfortable in terms of bounce characteristics, but are expensive and difficult to repair and maintain. These floors have always had the risk of injury, such as abrasions, to the player who fell on the floor. Therefore, wood and fixed tiles or cement floors can be used for sportsmen jumping, running and running. The disadvantage is that it cannot absorb the transverse impact forces common to sporting activities involving sudden changes.

Conventionally known technology is a horizontal impact force absorbing modular tile No. 10-0075841-0000 (1994.07.28).

The Patent Document 10-0075841-0000 (1994.07.28) 'horizontal impact force absorbing modular tiles' are structurally made of a plastic material as a modular tile and usually adopts a grid structure so that the tile surface extends downward from the grid intersection. It is a cross pattern with support legs that are close together.

The patent is described in more detail, which includes the use of expansion joints and cross reinforcement members or stiffeners, the grid structure being modular tiles with a continuous flat surface, which is more likely to bend and bend, and the surface is more likely to It tends to be much more twisted and bent when it is received. As a result, the prior art has made it impossible to use plastic tiles with a continuous, flat surface and interlocked in a modular and circulating manner.

The main reason for avoiding flat and continuous surfaces is the difficulty of producing and maintaining plastic tiles that are placed at the same height on the support floor surface without adhesives, despite changes from temperature and long-term use. In the case of tiles, temperature changes can cause the tiles to bend and limit the effective use of the tile floor, such as surfaces that are exposed to sunlight or fire, as well as lifting vertices or edges, creating safety hazards, and breaking parts. If this occurs, there is a problem that the bleeding of the breakage occurs quickly due to the lateral or diagonal force or frictional force by the continuous exerciser and the user.

In addition, there is a problem that the drainage is not easy in the case of the tile adhered to the hardwood floor or the cement cement floor during rainfall.

The present invention has been made to provide a more improved prefabricated sports court to solve the above problems and to solve the problems of the prior art, to provide a sports stadium surface, such as basketball, tennis, futsal, etc. To plastic tiles or floor coverings which are supported on the floor, in particular plastic sports courts which are interlocked to form a stadium surface which requires both friction and safety imposed by sudden lateral forces during use.
