Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming a part of a corner of a wall using a board with a textured surface.

In recent years, a cement composition is mixed with finely chopped hard wood chips and water, and this is formed into a predetermined shape. Wood chips, cement boards, plywood, etc. are often used as wall materials for housing structures.

When forming a part of a structure using such a wall material, for example, 249. If the cross-sectional structure is such that the ends of the hard wood j1 cement 1-board 1.1 are cross-joined in a cross-sectional manner, the end 2 of one of the boards will be exposed at the joint of the hard wood element board 1.1.

However, in the structure of this board, the grain size of the wood chips is fine in the areas near the front and back surfaces, so the blending ratio of cement I is high, while in the center, which accounts for most of the wood chips, the grain size is coarse, and the wood chips mix fIj is very low. Since the wood is covered with strawberries, the waterproofing of the end of the wood is insufficient. Similarly, in the case of plywood, the waterproofness of the end of the wood is inferior. However, the exposed end of the wood is not aesthetically pleasing, and there is a level difference at the joint.

Therefore, as shown in Fig. 2, a roughly V-shaped groove is carved in two intersecting hard wood pieces cement 1 to board 1, and the joint part forms an obtuse angle to form a corner hole 1b. A method has been proposed in which a part of the corner of an exterior wall of a house is formed by gluing together hard wood pieces, cement boards 1a, and ICs in a substantially V-shaped full surface 3r.

A part of the corner of such a structure is formed by forming a 17-shaped groove 4 in a hard wood cement board 1 as shown in FIG. That is, hard wood cement 1 to board 1 are cut 2 with a cutter (not shown).
A parallel 17-figure groove 4 is formed in the book. Next, adhesive is applied to the inner surface 3 of this substantially V-shaped groove. Finally, both sides of the hard wood cement board 1 are lifted in the direction of the arrow, and the adhesive is heated and hardened while maintaining the shape of a part of the corner as shown in FIG.

In the process of forming the approximately ■ character 4 on the hard wood cement board 1, it is difficult to accurately control the cutting depth of the cutter. An adhesive backing sheet 5 is attached to the back side of the cement board.

During such bonding work, the surface of the hard wood cement board 1,
That is, on the surface of the hard wood cement board that is in contact with the adhesive backing sheet 5, a cutting material 1 for decorative purposes as shown in FIG.
If there are four parts 6 perpendicular to the figure 7 groove 4, the figure 17 groove 4
The adhesive applied to the inner surface of the four parts 6 flows into the recess 6, resulting in poor adhesion due to insufficient adhesive, and poor appearance due to adhesion of adhesive to the four parts 6.

The present invention solves the above-mentioned problems by providing a plate material having a concave portion on its surface. - It is an object of the present invention to provide a method for forming a corner part of an external wall by forming a corner part.

According to the method of forming part of the outer wall of the present invention, a backing material is inserted in advance into the four parts formed on the surface of the board material, and an adhesive backing sheet is adhered to the top surface of the backing material. After that, from the back side of the plate material, cut the backing material into 6 pieces by cutting the 1lIi shielding side + Jchi sheet (approximately V-shaped) blue, and apply adhesive to the inner surface of the approximately ∙-shaped part. The plate material divided by the 17-shaped groove is bonded via the inner surface of the substantially V-shaped groove.

The details of the present invention will be explained below with reference to the drawings showing one embodiment thereof.

FIG. 6 is a partial side view of a hard wood cement board showing an example of applying the method of the present invention.

In Fig. 6, on the surface of hard wood cement 1 to board 1, 1
In order to cut and form the 7-shaped groove 4, apply adhesive backing f1 in advance]
5 is attached. Further, on the surface of the hard wood cement board 1, a curved backing ltA 7 made of urethane foam, for example, is inserted into the four parts 6 perpendicular to the 17-shaped groove 4.

The backing material 7 may be fixed to the inner surface of the four parts 6 via an adhesive. Further, if the backing material 7 is integrated with the adhesive backing sheets 1 to 5, the pasting work is easy.

If the backing material 7 is attached to the inner surface of the four parts 6, when cutting and forming the approximately V"?' groove 4, the hard wood cement board 1
The lining effect is high, and it is possible to prevent the hard wood pieces from being damaged at the concave parts 1 to 2 of the board 1.

The adhesive backing sheet 5 is preferably a thick woven fabric impregnated with a rubber adhesive. Alternatively, a plastic snack film coated with an adhesive may be used.

When forming the 17-shaped groove 4, the cutter blade cuts the hard wood cement] - The thickness of the adhesive backing sheets 1 to 6 is sufficiently thick so that it can completely cut the board 1 and further cut into the adhesive backing sheet 6. It is preferable.

III with 17-shaped grooves 4 formed as shown in Figure 6! As shown in Fig. 4, the wooden cement board 1 is shaped into a part of the corner by applying adhesive to the inner surface of the 17-shaped groove 4 with the adhesive sheet 5 attached to it, and then heated and hardened. . The adhesive backing sheet 5 is then peeled off from the board 1 onto the hard wood block 1. For this reason, it is preferable that the adhesive backing sheet 1 to 5 has an adhesive layer with good removability. The same applies to the adhesive layer formed on the backing vJ7.

Figure 7 shows the backing tA7 cut into hard wood cement 1 to board 1. When the adhesive is applied to the inner surface of the approximately V-shaped ff/i 4, the adhesive does not run off or adhere to the inner surface of the 4 rli 6.

If the backing material 7 is removed from the recess after the above adhesive process is completed, the recess will be protected from stains caused by the adhesive and a beautiful finish will be achieved. After the completion of a portion of the corner, the surface of the hard wood cement 1 is painted, etc., and becomes the outer wall of a house or the like.

In addition, the reference numeral 9 in the figure is an adhesive surface portion of the adhesive provided on one or both of the substantially V-shaped groove surfaces 3.

By setting the glue surface 9 in this way and performing the adhesion process,
The adhesive applied to the approximately V-shaped groove surface 3 is held by the adhesive surface, and both edges of the approximately V-shaped groove surface 3 are adhered, and when heated for adhesive assimilation treatment, this becomes a moderate adhesive surface. This prevents adhesive from overflowing and causing poor adhesion due to insufficient adhesive. In this way, there is no need to apply excess adhesive to the extent that it extends to surfaces other than the adhesive surface, resulting in a beautiful finish.

According to the method of forming part of the corner of the wall of the present invention described above, the step of cutting and forming a substantially V-shaped groove on the back surface of the board material and the subsequent gluing step are simple, and moreover, the process of forming a substantially V-shaped groove on the back surface of the board material is simple. Since the adhesive does not run away, poor adhesion can be prevented. Further, the substantially V-shaped groove cutting surface and the recessed portion of the plate material can be protected from contamination by the adhesive.

This also makes it possible to form part of a corner of a wall with a beautiful appearance.

Furthermore, if the adhesive surface is provided on the approximately V-shaped groove surface, the adhesive can be applied sufficiently to the joint, and since the adhesive is held on the adhesive surface, there may be insufficient adhesion and poor adhesion. It never happens. Furthermore, the adhesion is performed at both edges of the substantially V-shaped groove, and the bonding strength is extremely high.
