Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a floor construction method using a viscous hot-melt adhesive such as resin mortar, and an apparatus therefor.

(Prior technology) Conventionally, when performing floor covering work with viscous materials such as resin mortar, solution-type resins are mixed with aggregate using a batch mixer, etc., but because the material is viscous, it is extremely difficult to do so. Since it is difficult to knead and the curing time is short, it must be kneaded in small quantities.

In addition, leveling is carried out using pie break-1 trowels, tamping plates, rotating rollers, box-shaped materials, pipes, and screw-type rotating materials, either alone or in combination.For resin mortar, manual work using a metal trowel is the best. Common.

(One Problem to be Solved by the Invention) However, in the conventional construction described above, the following problems have arisen because the pot life of the material is short and the material has high viscosity and adhesiveness.

i) During kneading, since the pot life is short, only the amount that can be worked within the pot life can be kneaded, and the kneading cannot be left for a while.

ii) Because the pot life of the material is short, the mixer etc. must be cleaned frequently.

iii) After kneading, the material whose pot life has passed cannot be used, resulting in a large material loss rate.

iv) Manual work is a burdensome work that requires strength and is difficult to perform in large quantities.

(2) Workability is very poor because the material adheres to the leveling member and finishing member and is viscous.

vi) It is difficult to achieve a continuous smooth finish, and undulations, scratches, etc. are likely to occur.

vi) Leveling and finishing work requires skill and is very hard work.

The present invention has been proposed in view of the above-mentioned problems of the prior art, and its purpose is to eliminate the need for floor finishing to be carried out by mechanical construction from beginning to end, and to be affected by unevenness of the floor surface. To provide a floor construction method and device using a heat-melting adhesive, which enables a continuous smooth finish without any problems, eliminates waste of materials, improves workability, and saves labor.
