Description of the Related Art Generally, when constructing a concrete flooring material having a large area, joints are provided at appropriate intervals in order to prevent irregular cracking. Conventionally, the method of constructing this joint is to pour wood joints at the same time when concrete is poured, remove this wood joint after hardening of the concrete, and joint material such as mortar, sealing material, synthetic resin in the formed grooves. It was kneaded at the site and then embedded, or cut into an appropriate size at the site and then embedded.

すると云う欠点が存在した。By the way, in the above-mentioned conventional joint construction method, a wood joint is placed in a concrete placing site, and after the concrete is hardened, the joint is removed to form a groove. Since the joint material such as a synthetic resin is kneaded and mixed, and the construction is performed on the spot or is used by stirring on the spot, the construction is time-consuming, and the cost is high. Also, because the conventional joint material itself is soft and wears, durability, hot water resistance, oil resistance, wear resistance, shrinkage resistance, chemical resistance, heat resistance are inferior,
When it is used in a food factory or a kitchen, it is deteriorated by hot water or oil spilled on the floor surface, and there is a drawback that water leakage or oil leakage occurs from joints.

Here, the joint material 18 is made of one-component polyurethane, and has a substantially trapezoidal shape in cross section, which is composed of a side B perpendicular to the base A, a slope C, and a side D parallel to the base A. Therefore, the base A and the side B and the side D and the side B are orthogonal to each other. In addition, the oblique side C is formed with unevenness 19 over the entire surface.

る。The joint material 10 is attached by fitting the leg portion 12 coated with the adhesive into the formed joint groove 21. Since the head 11 of the joint material 10 projects from the concrete 20 surface, the synthetic resin-based floor covering 23 is formed to the same height as the top of the head 11. In this case, the synthetic resin-based floor covering 23 is a methyl-meth-acrylic (MM
It is formed by applying A) or an epoxy resin or the like.

Even when used, there is no risk of the joint material being scratched or worn even when the forklift or the like steps on it. Even if spilled oil or hot water is spilled on the floor, there is no risk of deterioration of the joint material.

Since the head portion 15 of the joint material 14 is formed in a substantially semicircular cross section, the sealability of the joint material 14 can be improved. Further, since the unevenness 17 is formed on both surfaces of the leg portion 16, the adhesive can be made to fit well. Therefore, the joint material 14 is less likely to come off from the joint groove 21.

The joint material 18 is arranged with the bottom side A facing downward at a position facing the U-shaped groove 22 on the floor surface on which the concrete 20 is cast. Then, a synthetic resin-based flooring material 23 is formed by applying methyl-meth-acrylic (MMA) or the like so as to be flush with the side D of the joint material 18. Furthermore, hanging side B
Also, if an adhesive is applied, the joint with the U-shaped groove 22 is improved and water leakage can be prevented.

い。As described in detail above, the jointing material of the present invention is made of one-component polyurethane, and has a cross-sectional shape of a head and a leg hung from the head. A plurality of irregularities are formed in the joint, and the joint construction method is a step of forming joint grooves with a cutter after hardening in the placed concrete, and a leg portion of joint material composed of a cross section head and leg portions in the joint groove. Since it consisted of a step of applying an adhesive to the fitting and fitting it, and a step of applying the synthetic resin to a height equal to the top of the fitted joint material, it is possible to effectively use the cracks of the placed concrete as an expansion. Can be absorbed. Further, since the joint material of the present invention is excellent in durability, hot water resistance, oil resistance, abrasion resistance, shrinkage resistance, and chemical resistance, the floor material may be damaged even if hot water or high temperature oil is poured onto the floor surface.
