DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint material for connecting concrete products such as a curb block, a sidewalk block, and a median strip block, and various stone materials, and to a connecting method.

[0002]

2. Description of the Related Art Conventionally, connecting concrete products such as curb blocks and various stone materials has been performed as follows. That is, curb blocks and the like are arranged side by side with a predetermined joint gap using a gap gauge or the like, and the gap is filled with mortar to form joints. Curing is performed by using a curing tape or the like so that mortar does not adhere to both sides of the gaps of the concrete product or the like.

[0003]

In the above-mentioned conventional connection construction method, the use of mortar requires curing to prevent contamination, and the work of adjusting the interval with a gap gauge and kneading the mortar is complicated, and the work efficiency is reduced. Was bad. In addition, there is also a problem that after the construction, the arrangement of the concrete products and the like connected and connected is disturbed by expansion and contraction of the concrete products and the like due to a temperature change or the like.

[0004]

SUMMARY OF THE INVENTION The present invention solves all of the above-mentioned problems, and is intended to provide a joint between concrete products and the like.
In the construction method of connecting through the body, both sides of the main body, which is a thin plate with the same shape as the shape of the connecting surface of concrete products etc. and has almost the same thickness as the predetermined joint width, are made adhesive surfaces, and a protective sheet is attached to the surface Concrete through joints
A consolidated construction method of concrete products such as linking the products and the like.

[0005] As a material for the joint material main body, various materials such as soft resin, sponge, foamed plastic, elastite (trade name), and a mixture of coal tar and fiber can be used in addition to recycled paper. The adhesive surfaces on both sides of the main body are formed by applying an adhesive or attaching a double-sided adhesive tape.

[0006]

According to the present invention, both sides of the main body having the same thickness as the predetermined joint width in the form of a thin plate having substantially the same shape as the shape of the connecting surface of a concrete product or the like are provided with an adhesive surface, and a protective sheet is attached. Since joints are used to connect concrete products, etc. using the jointing material, after setting the concrete product, etc. in a predetermined position, the protective sheet on one side of the jointing material is peeled off and adhered to the connecting surface of the concrete product, etc., and the other one side The protective sheet is peeled off, and the connecting surface of the next concrete product or the like is adhered to the protective sheet, and by repeating this operation, the connecting work of the concrete product can be easily performed with a predetermined joint width.

When the main body is made of a somewhat soft and elastic material such as recycled paper, soft resin, sponge, foamed plastic, etc., the adhesion to the concrete surface during bonding is improved, and the bonding effect is increased. In addition, after construction, expansion and contraction of the concrete product due to a temperature change or the like can be absorbed, and the arrangement of the concrete products connected and constructed can be prevented from being disordered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing embodiments. FIG. 1 is a perspective view of a joint material 1 according to one embodiment of the present invention, FIG. 2 is a partial cross-sectional view of the joint material 1, and FIG.

The joint material 1 is used for connecting the curb blocks. The main body 2 is formed in a thin plate shape having substantially the same shape as the shape of the connecting surface of the curb blocks, and has the same thickness as a predetermined joint interval. And a silicone film as the decorative material 3 is formed on the outer periphery of the recycled material of the used paper. Recycled waste paper is obtained by cutting the recovered waste paper into small pieces, adding a chemical to the mixture, and putting it into a mold to form a mold. Body 2
Both sides have an adhesive surface 4 coated with an adhesive, on which a protective sheet 5 is affixed. Various known adhesives can be used as the adhesive. The protective sheet protects the adhesive by the time of use.

When connecting the curb blocks, first, the first curb block 6 is set at a predetermined position, and the joint material 1 from which the protection sheet 5 on one side is peeled is bonded to the connecting surface. Next, peel off the other protective sheet 5 on one side of the joint material,
The connecting surface of the second curb block 7 is left standing there as if it is bonded, and a wood is hit, and the crimping is performed by lightly tapping with a hammer. This operation is sequentially repeated, and the curb blocks 8 and below are connected and constructed.

[0011]

Consolidated construction side of the concrete products of the present invention, according to the present invention
Since the method does not use mortar, it does not require curing for dirt, and does not require adjusting the gap with a gap gauge or kneading mortar, thereby simplifying the operation. In addition, by using a slightly soft and elastic material such as recycled paper, soft resin, sponge, and foamed plastic for the main body, the adhesion to the concrete surface during bonding is improved, and the bonding effect is increased. After the construction, the expansion and contraction of the concrete product due to a temperature change or the like can be absorbed, and the arrangement of the connected concrete products can be prevented.
