[Structure] Rubber tiles 3, which are a combination of a decorative front board 1 and a back board 2, are laid on an existing floor surface without any gaps. For example, elongated projections 2a are formed along, for example, four sides of the flat plate portion of the back plate 2, which has a square plan view. The decorative surface board 1 is fitted into the recess formed in the back plate 2 by the projections 2a, and preferably adhered. When the rubber tiles 3 are laid, the protrusions 2a of adjacent rubber tiles are continuous with each other, forming a grid-like joint pattern as a whole.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention can be used in various applications such as office buildings, golf course clubhouses, guest houses, etc. This relates to rubber tiles used for construction on the floors of facilities.

0002

[Conventional technology]

Traditionally, rubber tiles were used to install on existing concrete floors. The two-layer structure consists of a back layer that is laid on top of the floor, and a decorative surface layer that forms a new floor surface. Rubber tiles made of vulcanized rubber are known.

0003 Construction methods for these rubber tiles include finishing the outer circumference of the rubber tile at right angles. , or after chamfering, lay multiple rubber tiles in contact with each other to cover the existing floor surface. There is a way to cover it.

0004 However, if you simply lay rubber tiles of the same standard and color over the entire surface of the existing floor, The disadvantage was that there was no space on the floor surface, making it visually and visually monotonous to walk on. Special In addition, at the construction sites of recent upscale office buildings and various facilities, residents, Since the sense of pedestrians is important, it is necessary to eliminate the above drawbacks as a construction material. Ru.

[0005] The second construction method is to install the rubber tiles above on the existing floor. A certain gap is provided between the rubber tiles, and the existing floor surface is inserted through this gap. Expose it and fit a long rectangular joint material into this gap, or use a liquid solidified material. The joints were formed by injecting material or putty and letting it harden.

[0006] However, at construction sites, rubber tiles are laid exactly at a certain distance apart. To install it, you have to match each dimension at the construction site, which is very time-consuming. It takes time and requires skill. Also, the liquid material is uniformly distributed between the rubber tiles. The construction of injecting water into the concrete was difficult and required a great deal of labor and time.

[0007] For this reason, as a simple method, once the above rubber tiles are laid densely, each There was a construction method in which printing was applied to the periphery of the tile to serve as a joint. However, in this case, Printing occurs when many people walking on the floor wearing leather shoes, spikes, shoes, etc. The disadvantage was that only the parts were worn out and peeled off, resulting in an extremely unsightly condition.

[0008]

[Problem that the idea aims to solve]

The problem with this invention is that it takes a lot of effort and time to lay rubber tiles on an existing floor surface. To make it possible to easily form a joint pattern without peeling and to prevent peeling of the joint pattern. That is.

[0009]

[Means to solve the problem]

Also, the plane square Long and thin protrusions 2a with a rectangular cross section are provided along the periphery of the four sides of the flat plate part 2b, and the flat plate part 2b is The periphery of the portion 2b is surrounded by a protrusion 2a. The flat portion formed by the flat plate portion 2b and the protrusion 2a The surface decorative board 1 is fitted into the square-shaped recess. At this time, the surface decorative board 1 is b and the protrusion 2a.

0012 When laying this rubber tile 3, in the same way as conventional rubber tiles, the back layer 2 is The outer walls are brought into contact with each other and arranged without any gaps. As a result, the surface of the protrusion 2a automatically appears in a checkerboard pattern, forming a joint pattern.

[0013] With these rubber tiles, it is possible to form a grid-like joint pattern. It gives a moderate accent to the floor surface and gives a sense of comfort to residents and pedestrians. Designs can be added to the floor.

[0014] Moreover, unlike conventional methods, rubber tiles are laid at a certain distance apart. by inserting long strips of grout into the gaps between rubber tiles, or by injecting and hardening liquid materials. There is no need for troublesome construction work such as installation. Therefore, construction is easy and the construction period can be shortened. It can be shortened and construction costs can be reduced. What's more, by printing on the surface of the rubber tile, Unlike the case where joints are formed, there is no peeling of the joints and there is little wear.

[0015] The width of the protrusion 2a is preferably about 2.5 to 10 mm. Also, in the state shown in Figure 2 The height of the protrusion 2a is the same as the surface of the surface decorative board 1, or is slightly lower. It is preferable to do so. If the joints protrude from the floor, it will be difficult to walk on. Ru.

[0016] The front decorative board 1 can also be fixed to the recessed part of the back board 2 only by fitting. However, at this time, it is preferable to further bond the front decorative board 1 to the back board 2. This is it For example, if you walk on the decorative surface board 1 with a spike, etc., the decorative surface board 1 will come off. There is no risk of it happening. The color of the surface decorative board 1 and the color of the projections 2a should be considered so that they harmonize with each other. It is possible. Specifically, it is important to have the same color tone, pastel tones, primary colors, and metallics. Consideration should be given to arranging special hues, complementary color relationships, transparency, warm and cool color relationships, etc. I can consider it.
