Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall surface forming method for forming a wall surface by adhering boards to a wall surface underlayer with an adhesive.

[0002]

2. Description of the Related Art Conventional methods for forming inner walls of houses, offices and the like include a wet method known as a GL method or a sword finishing method, and a dry method known as a screw packing method.

[0003]

However, each of the construction methods has the following drawbacks.

First, since the so-called water-based adhesive obtained by adding water to a plaster-based adhesive and kneading it is used in the wet method, the moisture contained in this adhesive causes the problem. There is a high risk that mold will occur on the surface of wall finishing materials. In addition, since it takes about one week for the water-based adhesive to dry, the work period becomes longer. Furthermore, in the wet method, the water-based adhesive is made into a dumpling state and applied to the concrete surface, and then the finishing board is pressure-bonded from above, but such pressure-bonding should be used to level the board. Requires considerable skill.

On the other hand, in the dry method, an adjustment stand made of vinyl chloride and metal fittings are fixed to the wall surface by adhesion, leveling is performed after drying, and then the plaster board etc. are fixed with nails, screws, etc. A lot of man-hours,
Not efficient. Therefore, it is not suitable for large-scale construction.

An object of the present invention is to propose a wall surface construction method capable of solving the problems of the conventional construction method.

[0007]

In order to solve the above problems, in the method of the present invention, the wall surface is constructed as follows. That is, first, a plate-shaped member having a mounting hole for mounting a temporary fixing tool and an injection hole for injecting an adhesive material is prepared. Next, in the insertion hole of this plate-shaped member,
A temporary fixing tool for temporarily fixing the plate member to the wall surface is attached. Next, the plate member on which the temporary fixing tool is mounted is installed on the wall surface, and the tip end of the temporary fixing tool is fitted into the wall surface to temporarily fix the plate member on the wall surface. Then, the temporary fixing tool attached to the temporarily fixed plate-shaped member is adjusted, and the level of the plate-shaped member is leveled at a predetermined distance from the wall surface. Next, an adhesive is injected into the gap between the plate-shaped member and the wall surface through the injection hole of the plate-shaped member to bond and fix the plate-shaped member to the wall surface. Finally, the temporary fixing tool is removed from the plate member.

Here, it is desirable that after the temporary fixing tool is removed from the plate member, the adhesive is further injected into the gap between the plate member and the wall surface through the mounting hole.

Further, it is desirable to use a resin liquid as the adhesive material. In particular, it is preferable to use a hard urethane liquid. In this case, in consideration of the foaming of urethane, the adhesive is injected in a dumpling shape so that the gap between the plate member and the wall surface is partially filled with the adhesive. It is desirable to inject so that

Next, as a temporary fixing tool used in the method of the present invention, an outer cylinder which can be removably screwed into and fixed to a mounting hole of a plate member, and an inner cylinder which extends through the outer cylinder. It is preferable that the inner cylinder is composed of a distal end portion that is detachably supported on the distal end of the inner cylinder, and the inner cylinder can be fixed to a predetermined position in the axial direction with respect to the outer cylinder. In this case, the temporary fixing tool can be mounted in the mounting hole by screwing the outer cylinder of the temporary fixing tool into the mounting hole of the plate member. Also, when adjusting the level of the temporarily fixed plate-shaped member,
The relative position in the axial direction between the inner cylinder and the outer cylinder of each temporary fastening tool may be adjusted to adjust the distance between the wall of the plate member to which the outer cylinder is fixed and the wall surface.

The mounting hole and the injection hole formed in the plate-shaped member are preferably formed as holes of the same size. Further, it is desirable to use a gypsum board as the plate member.

It shows a state in which is attached.

Next, as shown in FIG. 6, the gypsum board 1
(1-1, 1-2, ...) is leaned against the wall surface W. In this example, the wall surface is a concrete frame.

After the gypsum board 1 is leaned against the wall surface W in this manner, an air gun 4 is used as shown in FIG.
Using the hollow portion of the temporary fixing tool 3, the temporary fixing pin 33 supported by the tip of the temporary fixing tool 3 is driven into the wall surface W.

Next, as shown in FIG. 8, a temporary fixing tool 3
The bolt member 32 of 1 is screwed in by a predetermined amount. By doing so, the side of the nut member 31 fixed to the side of the gypsum board 1 is placed on the outer periphery of the bolt member 32 so that the gypsum boat 1
Together with this, it moves away from the wall surface W. Therefore,
By adjusting the screwing amount of the bolt member 32 of each temporary fastening tool 3, the plasterboard 1 can be leveled with respect to the wall surface W.

Thereafter, as shown in FIG. 9, an adhesive injection gun 5 is used to remove the hard urethane liquid as an adhesive.
It injects from each injection hole 2b of the gypsum board 1. The injection is not performed so as to fill the entire gap 6 between the gypsum board 1 and the wall surface W, but as shown in this figure, the hard urethane 7 in the form of dumplings is used.
Are formed. As the injection gun, a commonly used one can be used,
A dedicated injection gun for carrying out the method of the present example may be manufactured and used.

Next, after the hard urethane 7 is dried and hardened so that the gypsum board 1 is securely fixed to the wall surface W, as shown in FIG. The temporary fixing tool 3 is removed from the hole 2a.
Here, since the temporary fixing pin 33 supported by the tip of the temporary fixing tool 3 is driven into the wall surface W, it remains in the state of being directly driven into the wall surface W.

After this, as shown in FIG. 11, the mounting hole 2
