Description

[0001] MODULAR ELASTIC FLOORING [0002]

The present invention relates to a modular elastic flooring, and more particularly, to an elastic mattress such as a urethane board, which can be installed on the ground in units of modules, and a drainage groove of the drainage block interconnecting the flooring modules So as to improve water dripping.

In recent years, flooring materials such as outdoor basketball courts made of tile, concrete, or asphalt and building materials such as asphalt have been widely used as a means of replacing land tracks made of soil or the like, and elastic flooring materials such as urethane boards are widely used in various sports, .

Such flooring material of elastic material is required to ensure drainability especially when it is installed outdoors. For this purpose, it is necessary to form a drainage passage between the ground and a separate drainage block.

That is, for example, a conventional rubber mat for floor (shown as reference numeral 101 in Figs. 1 and 2) (Patent Publication No. 10-2011-0010437) has a plurality of tunnel portions 105 for drainage on the bottom surface of the valve element 103, And male and female coupling means 107 and 108 for coupling with the adjacent mat 101 are formed in pairs so as to correspond to the corner portions of the plate body 103. [

Therefore, in order to construct a floor material or a land track by the rubber mat 101, first, a floor is to be formed on the ground to be grounded, a drainage facility such as a pond is installed, And the rubber mat 101 is laid on the rubber mat 101 after the rubber mat 101 is laid on the elastic layer so that the construction of the equipment is increased and the air and the construction cost are increased. Dust and the like.

In addition, when the rubber mat 101 is applied, the male-type assembly protrusions 107 protruding from one side edge are matched with the female-type assembly grooves 108 embedded in the other side edge of the adjacent mat, And forms a long drainage passage connected to the neighboring tunnel portions 105 corresponding to the plurality of tunnel portions 105, respectively.

However, since the conventional rubber mat 101 as described above is formed by directly working the tunnel portion 105 on the bottom surface of the plate body 103, the thickness of the plate body 103 on the tunnel portion 105 is greatly reduced, There is a problem that the inherent performance of the rubber mat 101 is deteriorated such as lowering the strength.

In addition, when the tunnels 105 are formed on the assembly protrusions 107 having a relatively small thickness, crossings are generated between the tunnels 105 and the assembly protrusions 107 as shown by A in FIG. 1, If the height of the tunnel part 105 is made low or the height of the tunnel part 105 is not made to prevent such decrease in strength, the drainage performance of the tunnel part 105 is lowered There is a problem in that the inner mouth and drainage performance of the rubber mat 101 is deteriorated due to structural interference between the tunnel part 105 and the male and female coupling means 107,

If the area or depth occupied by the tunnel part 105 is reduced in order to reduce the performance degradation as described above, the drainage performance may deteriorate. In particular, when the quantity of the water is increased due to heavy rain, There is a problem in that it can not be performed smoothly.

Further, since the tunnel portion 105 is exposed on the construction surface, that is, the ground surface, when the drainage pressure is increased or the drainage is continuously repeated, the floor is lost and the floor made of the rubber mat 101 is damaged or lost There was also a problem.
