Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for widely applying an adhesive to the floor surface of structures such as buildings and roads in preparation for pasting flooring materials. Regarding the method.

[Conventional technology]

Flooring materials such as carpets, hard or soft vinyl tiles, and vinyl sheets are pasted on the floors of buildings such as houses, offices, and factories, as well as on corridors and roads, for interior and exterior decoration and aesthetic purposes. ing.

The flooring material is attached to the floor surface by applying an adhesive onto the floor surface and pressing the flooring material thereon. Adhesives used in this case include liquid reactive adhesives such as epoxy resins, solution-type adhesives such as polyvinyl acetate and chloroprene rubber dissolved in organic solvents or water, polyvinyl acetate, and synthetic rubber. There are also emulsion-type adhesives made by emulsifying acrylic acid ester resins, etc.

When applying flooring materials, the above-mentioned adhesive has a relatively high viscosity, and it is necessary to apply the adhesive thickly and in a wave pattern to the surface to be coated, so the application of the adhesive is difficult.
Traditionally, it has been done manually using a triangular plate-shaped tool called a kushigote. A skilled worker who attaches flooring materials can apply the adhesive by skillfully manipulating the trowel and drawing a horizontal figure eight shape on the surface to be coated.

[Problem that the invention seeks to solve]

The conventional method of applying adhesive using a trowel requires the worker to work in an awkward position, such as bending over, and when using an adhesive containing an organic solvent, the evaporated organic solvent may be deposited near the floor surface. There is a risk that it will accumulate and cause undesirable results in terms of occupational health, such as adversely affecting the health of workers.

Furthermore, in the application work using the conventional adhesive application method, the application area is narrow because the worker bends over, and the application speed is slow, resulting in poor work efficiency.

SUMMARY OF THE INVENTION An object of the present invention is to provide an adhesive application method that eliminates the above-mentioned problems, allows workers to work in a comfortable posture, and does not cause any problems in terms of occupational health.

[Means for solving problems]

The adhesive application method of the present invention is applied to the floor surface of a building by spreading the adhesive aggregate supplied to the floor surface with the application plate with one side of the application plate facing the floor surface. When applying, move the applicator plate of the applicator below in a zigzag pattern from the front toward you while standing, to avoid adhesive leakage from the sides of the applicator plate. It is characterized by applying adhesive in a pattern.

Applicator: Consists of an applicator plate and an applicator plate shank to spread the adhesive over a wide area on the floor of a building.The shank is bent at the applicator plate side and joined to the applicator plate surface, Adhesive applicator used in the method of the present invention, the applicator having a rotation device for its shaft in the part thereof, and a gripping part for controlling the direction of the applicator plate being pivotally connected to the applicator plate shank. This will be explained with reference to FIGS. 1 to 3 showing a specific example of No. 1. The adhesive applicator 1 of this specific example consists of an applicator plate for widely spreading adhesive onto the surface of a building and an applicator plate shank, and this shank bends at that part on the applicator plate side and joins with the applicator plate surface. This applicator has a rotating device for its shaft at the bending portion of the shank on the applicator plate side, and a gripping portion for controlling the direction of the applicator plate is pivotally attached to the applicator plate shank.

The adhesive applicator 1 of this example operates as follows.

In the adhesive applicator held by the left and right hands of the worker by the upper part of the shank and the grip part 3, the grip part 3 provided at the upper end of the shank 4 is
Since it is linked to the shank 4 and the coating plate 2, the direction of the coating plate 2 can be controlled by the movement of the grip portion 3.

The worker who is applying the adhesive moves the applicator in a standing position as if he were using a broom.

At this time, avoid leakage of adhesive from the sides of the coating plate. A rotation device 5 is provided at a bending portion of the shank on the coating plate side, and the coating plate 2 is freely rotated around the shank axis of the bending portion. The rotating device allows the applicator to be moved and reversed without separating the floor surface and the comb-shaped tip of the applicator plate 2, thereby avoiding adhesive leakage from the sides of the applicator plate. Thus, the applicator plate can be moved in a zigzag pattern from the front to the front while the operator is standing.

The adhesive applicator 1 consists of an applicator plate 2 and its rod-shaped shank 4. The shank 4 is bent into a substantially L-shape at the end on the coating plate side. At the bent end of the shank 4, the shank 4 is joined to the coating plate surface at a certain angle. Here, the bending angle of the shank and the angle between the shank and the application plate can be changed depending on the type, shape, and size of the applicator, the type of surface to be coated, and the like. The other end of the shank 4 is formed into a substantially J-shape, and the grip portion 3 is provided therein so as to be substantially perpendicular to the shank axis.

A rotation device 5 is provided at a bent portion of the shank 4 on the coating plate side. This rotation device 5 allows the first
As shown in the figure, the applicator plate 2 is in the direction of arrows A and A', or the shank 4 is in the direction of arrows B and
It can be rotated in the direction of B'. An example of the structure of the rotation device 5 is shown in FIG. This device example consists of a large-diameter shank tube 5a and a small-diameter shank tube 5b, and the small-diameter shank tube 5b is fitted inside the large-diameter shank tube 5a and is rotatably attached.

The coating plate 2 in this example is joined to one end of the shank 4 at a constant angle to the coating plate surface or its extension surface. The shape and dimensions of the applicator plate can be changed depending on the type of surface to be coated, the use of the applicator, etc. The application plate 2 in this example consists of a comb-shaped iron plate 2c and support plates 2a and 2b that connect the plate to a shank, and the iron plate 2c can be detachably fixed to the support plates 2a and 2b. . Therefore, only the soldering iron plate 2c, which is subject to severe wear, can be easily replaced. In this example, the iron plate 2c is held between the support plates 2a and 2b, and is tightened with a nut 2d from above the support plate 2a. To replace the iron plate 2c, loosen the nut 2d and replace the iron plate 2c with the support plates 2a and 2b.
