Abstract

(57) [Summary] [Structure] A rubber chip layer is bonded to the surface of concrete. In particular, the rubber chip layers are displaced and combined to form protrusions on the adjacent side faces of the concrete, and at the same time, the protrusions are formed on the adjacent side faces of the rubber chip layer on the symmetrical side of the protrusions. [Effect] Since concrete is bonded to the lower part of the rubber chip layer, even if the ground is sandy ground, it can be quickly and inexpensively constructed as it is.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a block floor material having excellent cushioning properties and water permeability.

[0002]

[Prior art]

 Conventionally, this type of block floor material has been formed into blocks by crushing rubber chips and fiber-shaped buff powder with various binders.

[0003]

[Problems to be solved by the device]

 Since the above-mentioned conventional ones have low rigidity, they are generally applied on a mortar base. Therefore, when constructing on sandy ground, it is necessary to newly mortarize the groundwork, which is extremely time-consuming and therefore expensive. Therefore, an object of the present invention is to provide a block flooring material which is extremely easy to construct and can be inexpensively manufactured in order to solve the above problems.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the block floor material of the present invention has taken the following technical means. That is, in the invention of claim 1, the rubber chip layer is bonded to the surface of the concrete.

Next, in the invention of claim 2, the rubber chip layer is displaced and bonded on the surface of the concrete to form a protrusion on the adjacent side surface of the concrete, and the rubber chip on the symmetrical side of the protrusion is formed. Protrusions are formed on the adjacent side surfaces of the layers. Further, in the invention of claim 3, a rubber chip mat different in color from the rubber chip layer is bonded to the surface portion of the rubber chip layer.

[0006]

[Advantageous Effects] According to the present invention, since concrete is bonded to the lower part of the rubber chip layer, it is possible to quickly and inexpensively perform construction even if the ground is sandy. Next, according to claim 2, since the protrusion of the upper rubber chip layer is brought into contact with the protrusion of the lower concrete, the joint between the lower concrete is not visible, and the block is not formed on the sand. Even if it is partially sunk, the upper rubber chip layer fits with the surrounding blocks, so the steps between the blocks are less noticeable.

Further, according to claim 3, since rubber mats of different colors are bonded to the rubber chip layer, decorativeness is improved and added value as an interior art product is obtained, and by embedding the rubber mat, The design does not easily disappear even after wear.

【Example】

 Hereinafter, some embodiments of the present invention will be described with reference to the drawings. Example 1 (see FIG. 1) In FIG. 1, blocks 3 formed by bonding rubber chip layers 2 to the surface of rectangular concrete 1 are arrayed on a floor 4.

The rubber chip layer 2 is generally a waste material of a rubber molded product such as an old tire crushed into fibers or particles, or powder produced by a buffing process during the production of the rubber molded product (shape, size, etc.). Are not particularly limited), but these are bound by a binder such as rubber, epoxy, or urethane polymer. The rubber chip layer 2 is formed by coating the rubber chip on the surface of the concrete 1 with a coating or an adhesive.

According to Example 1 above, since the concrete 1 is bonded to the lower portion of the rubber chip layer 2, even if the ground is sandy ground, it can be quickly and inexpensively applied as it is. Example 2 (see FIGS. 2 and 3) In Example 2, when the rubber chip layer 2 was displaced and bonded to the surface of the concrete 1, the protrusions 1a and 1a were formed on the adjacent side surfaces of the concrete 1, and The protrusions 2a, 2a are formed on the upper portions of the protrusions 1a, 1a and on the adjacent side surface of the rubber chip layer 2 on the symmetrical side.

According to the second embodiment, in addition to the actions and effects of the first embodiment, since the protruding portion 2a of the upper rubber chip layer 2 is brought into contact with the protruding portion 1a of the lower concrete 1, the concrete of the lower layer is contacted. The joints between the doors are not visible, and even if the block 3 is partially sunk in the sand 4 as shown in Fig. 4, the upper rubber chip layer 2 fits with the surrounding block 3, The step between blocks 3 and 3 is not noticeable.

A manufacturing example of the second embodiment will be described with reference to FIGS. As shown in Fig. 5, concrete 1 is cast into the mold 5 composed of the lower mold, and then the uncured binder mixed rubber tip 2B is poured from above, and the mold 6 composed of the upper mold is arranged from above. As shown in FIG. 6, it is manufactured by compression. In this case, not only does the above-mentioned adhesive become unnecessary, but this can strongly bond the concrete 1 and the rubber chip layer 2 together.

Another manufacturing example will be described with reference to FIGS. 7 and 8. As shown in FIG. 7, after the hardened rubber chip layer 2 is placed in the molds 5A and 5B, the raw concrete is placed from above. Inject 1B and cure as shown in FIG. In this case, since the surface of the rubber chip layer 2 in contact with the mortar is formed to be uneven due to the bonding gap between the rubber chips, the mortar enters and is strongly bonded even without an adhesive.

Example 3 (see FIGS. 9 and 10) In Example 3, as shown in FIGS. 9 and 10, a rubber mat 11 different in color from the rubber chip layer 2 is embedded in the surface portion of the rubber chip layer 2. It is a combination. As the rubber mat 11, a rubber chip hardened with a binder may be used, or a vulcanized rubber molded body may be used.

The rubber mat 11 can use various designs such as numbers, direction indications, marks, Chinese characters and the like as decorations. According to the third embodiment, when the rubber chip layer 2 in which the rubber mat 11 is embedded is used, in addition to the above-described actions and effects, decorativeness is improved and added value as an interior art product is obtained, and the rubber mat is embedded. As a result, the design does not easily disappear even after wear.

A manufacturing example of the third embodiment will be described with reference to FIGS. As shown in FIG. 11, a pin 13 is embedded in the bottom part of the lower mold 12, a rubber mat 11 is driven into this pin 13, then an uncured binder mixed rubber tip 2C is poured, and then an upper mold 14 is placed from above. As shown in FIG. 12, it manufactures by compressing. Another manufacturing example will be described with reference to FIGS. As shown in FIG. 13, a partition 15 of an arbitrary shape is erected on the bottom of the lower mold 12a, a rubber chip 11d is filled in the partition 15, and a rubber chip 2D of a different color from that is filled. As shown in FIG. 14, the upper mold 14a is compressed to form a rubber chip layer 2 for decoration.

Although the rubber mat 11 is embedded in the rubber chip layer 2 in the above embodiment, the rubber mat 11 may be coupled so as to project above the rubber chip layer 2.

[Effect of device]

 According to the present invention, since concrete is bonded to the lower part of the rubber chip layer, even if the ground is sandy ground, it can be quickly and inexpensively constructed as it is. Next, according to claim 2, since the protrusion of the upper rubber chip layer is brought into contact with the protrusion of the lower concrete, the joint between the lower concrete is not visible, and the block is not formed on the sand. Even if it is partially sunk, the upper rubber chip layer fits with the surrounding blocks, so the steps between the blocks are less noticeable.

Further, according to claim 3, since the rubber mats of different colors are bonded to the rubber chip layer, the decorativeness is improved, the added value as an interior art product is obtained, and the design is improved even when worn. It has the effect of being hard to disappear for a long time.
