Description

[Detailed description of the invention] (Field of industrial application) The invention is a mosaic made of rubber blocks that are suitable for laying on sandy or uneven ground, and that do not create gaps and do not easily shift due to lateral stress. The invention relates to shaped sheets.

(Prior art) Conventionally, when a rubber sheet of this type is constructed by connecting rubber blocks with wire, etc., when it is laid on a sandy or highly uneven ground, it creates gaps and easily shifts due to lateral stress. It was hot.

(Problem to be solved by the invention) The present invention eliminates these conventional drawbacks, and is suitable for laying on sandy or highly uneven substrates, does not create gaps, and easily shifts due to lateral stress. The object of the present invention is to provide a mosaic-like sheet made of rubber blocks unlike any other.

(Means for Solving the Problems) As the embodiments of the present invention can be seen in the drawings, the present invention provides a rubber sheet in which a large number of rubber blocks are connected to each other in a substantially planar manner in the vertical and horizontal directions.
A large number of rubber blocks 2 having approximately the same desired thickness, a drum-shaped or I-shaped shape and the same size, and each having a stopper hole 1 at the center of the back surface thereof; The uneven portions 3 and 4 on the side surfaces are shifted to each other and fitted and combined in a mosaic pattern vertically and horizontally in a symmetrical manner, and then the rubber blocks 2 are connected to each other from the back surface by being fixed to the stopper holes 1 on the back surface. Reinforcement tape 5 for reinforcing connections between vertically and horizontally
and a stopper 7 for pushing and fixing the reinforcing tape 5 to the rubber block 2 through an opening 6 at a position opposite to the stopper hole 1 in order to maintain the connection. This is a mosaic-like sheet made of rubber blocks that is suitable for being laid on rough substrates, does not create gaps, and does not easily shift due to lateral stress.

Further, in the present invention, the rubber block 2 is made by hardening powdered rubber, or powdered rubber and thread-like or fibrous material, using a binder such as urethane or epoxy resin, or by vulcanization molding. As shown in FIGS. 1 and 2, the rubber blocks 2 can be fitted together and combined to form a mosaic sheet due to their shape, elasticity, and plasticity. There are no particular restrictions on size. As an example, the height is about 200mm and the thickness is about 30mm.
Normally, it is about mm.

As the reinforcing tape 5, plastic tape, fiber laminated tape, laminated tape, etc. can be used. The tape strength is preferably 100 kg/cm ² or more, the thickness is preferably about 50 μ to 2000 μ, and the tape width is preferably about 10 mm to 40 mm. Openings 6 are provided in the reinforcing tape 5 at regular intervals at predetermined positions corresponding to the stopper hole 1 located at the center of the back surface of the rubber block 2, and the stopper is inserted into the stopper hole 1 and the opening 6. 7, the reinforcing tape 5 is fixed to the back side of the rubber block 2, and the mosaic-like sheet made of the rubber blocks 2 is reinforced from the back side.

The stopper 7, which is pushed into the stopper hole 1 and fixed, is made of plastic, metal, etc., and may be of a screw type as shown in FIG. 4, or a wedge shape as shown in FIG.
The anchor bolt type shown in FIG. 5 can also be used.

(Function) In the present invention, the unit, that is, its constituent unit is a drum-shaped or I-shaped rubber block 2, and these blocks fit together in the vertical and horizontal directions to form a mosaic shape, and from the top and back surfaces. Since the reinforcing tapes 5 are used to strongly combine them, that is, to reinforce their connections, they are extremely superior while having appropriate elasticity and flexibility. It can adapt well to the irregularities of the base (surface) such as sand, and does not create gaps between blocks or cause misalignment due to lateral stress.

In addition, since the rubber block 2 as a constituent unit can be colored, it is possible to create a beautiful mosaic-like appearance.

(Example) To briefly explain the example with reference to the drawings, FIG. 1 shows a part of a mosaic sheet made of rubber blocks 2 in the shape of an hourglass. This rubber block 2
is evident in Figures 2a, 2b and 2c.

In FIG. 3, it can be seen that some of the I-shaped rubber blocks 2 are fitted in a mosaic pattern vertically and horizontally.

4 to 6 show embodiments of the stop 7. FIG.

(Effects of the invention) According to the invention, there is provided a mosaic sheet made of rubber blocks that is suitable for being laid on sandy or uneven ground, does not create gaps, and does not easily shift due to lateral stress. be able to.

Suitable for laying on golf course paths, sandy surfaces, and uneven substrates.

Also, the coloring of the rubber block gives it a beautiful appearance.
