Abstract

PURPOSE: To improve appearance by fixing an inner wall material and a bed material by a breaking off temporal stopping nail, applying a filling material to a nail hole after breaking-off, and wiping out a part protruded on the outer surface after the lapse of designated time. CONSTITUTION: An inner wall material 1 formed by taking a gypsum board or a calcium silicate plate as a base plate, and providing a synthetic resin layer or a wall paper layer on one surface of the base plate is impregnated to a bed material 3 by an adhesive 2, and a breaking-off temporal stopping nail 4 is driven in the surface of the inner wall material 1. Subsequently, after the adhesive 2 is dried and hardened, the nail 4 is removed from a cutout part 4b by bending. Subsequently, a filler 6 made by plastic mortar process of fine grain powder of the same family as gypsum, calcium silicate or the like with water is pushed into a nail hole 5 formed by bending and removing the nail 4. Further, when the filler 6 is nearly dried, the filler 6 on the nail hole 5 is wiped out.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method of forming a wall surface using an inner wall material having a substrate such as a gypsum board or a calcium silicate board.

(Prior art) When forming an interior wall by attaching a plurality of interior wall materials to a base material, it is not desirable to fix these interior wall materials by direct nailing because the nail heads will be exposed on the wall surface, which is undesirable for the appearance. Generally speaking, adhesive is applied to the back of each interior wall material in advance and fixed to the base material. In this case, the interior wall materials are fixed so that they do not move until the adhesive dries and hardens. For reasons of necessity, temporary fixing nails are driven from the surface side over the base material and removed after sufficient adhesion.

As shown in Fig. 6, this temporary nail generally has a ring 4a' made of hard synthetic resin inserted into the lamp body 4' up to the vicinity of the nail head. ' is pinched with a tool and the entire lamp body is pulled out.

Furthermore, there is a break-off type temporary fixing nail shown in FIG. 5 that has recently been developed for the purpose of eliminating the trouble of removing the temporary fixing nail. In this method, a ring body 4a made of elastic soft synthetic resin, rubber, etc. is inserted into the nail body 4 up to the vicinity of the nail head, and
A ring-shaped notch 4 is formed in advance in the striking body portion that is in contact with the inside of the ring body 4a.
After driving the transport body 4a to a state where it is sufficiently compressed and deformed, the ring body 4a is attached to the lamp body 4.
The light body 4 is separated from the notch 4 by tapping it in the direction perpendicular to the base material.In addition to eliminating the need for removal, the main part of the hammered light body is separated from the base material and the inner wall. Since the adhesive remains on the interior wall material, it has the advantage of reliably keeping the interior wall material fixed even if the adhesive is not completely dried and solidified, so it is suitable for attaching heavy interior wall materials such as gypsum boards.

(Problems to be Solved by the Invention) However, on the surface of the interior wall material tensioned in this way, nail holes remain after the part of the temporary nail that extends from the notch to the nail head has fallen off. These nail holes are the result of erosion where the notch of the light body remains deep inside, and if the interior wall material is wood board or fiberboard, it will shrink due to the material's elasticity and will not be so noticeable, but if the inner wall material is wood board or fiberboard, it will shrink due to the material's elasticity, but it will not be noticeable. In the product, these nail holes are quite noticeable and spoil the aesthetic appearance.

In other words, in order to break off the part near the outer surface of the temporary nail that has been driven in, hitting the nail head in a direction perpendicular to the lamp body with a tool will cause this erosion to form a hole that widens toward the mouth. As a result, this nail hole expands more rapidly in materials such as gypsum board, which has no resilience and is brittle.
Furthermore, since gypsum boards and the like are quite heavy, when driving temporary fixing nails, there is a risk that the inner wall material will move to one side, enlarging the entire nail hole.

However, filling the nail hole with adhesive caulking material in order to crush the nail hole on a wall that has been covered with adhesive, considering the possibility of erosion, will warp the nail hole edge and cause it to expand. Since the use of oil-based materials may cause smearing on the decorative surface, it has been thought that there is no other option but to leave the numerous remaining nail holes as they are.

(Means for Solving the Problem) On the other hand, the present invention provides a solution to a shallow nail hole after breaking off a portion close to the outer surface of a temporary nail. A filler made by softening fine powder of the same type as the calcium acid plate with water is applied into the hole until it reaches an appropriate depth while applying pressure that is not likely to destroy the edge of the nail hole, and after the required time has elapsed, These nail holes are closed by wiping off the protruding parts on the outside with a slightly wet or dry cloth.

(Embodiments of the Invention) The order of implementing the method of this invention will be explained with reference to the drawings.

(1) Using a gypsum board, calcium silicate board, etc. as a substrate,
The inner wall material 1, which has a synthetic resin layer or a wallpaper layer on one side and has a finely uneven decorative surface, is attached to the base material 3 via the adhesive 2, and the surface of the inner wall material 1 is folded at the appropriate place. Drive in the temporary fixing nails 4 of the mold (Fig. 1) (2) After the adhesive 2 has dried and hardened, break off the temporary fixing nails 4 from their notches 4b. (Figure 2) (3) Nail hole 5 formed by breaking off the temporary peg...
Separately, water is added to a powder material of the same family as the substrate, that is, a material of the same family as gypsum (lime sulfate), calcium silicate, etc., such as limestone powder, with an appropriate binder powder added. After the filler material 6 in a softened state is piled up, it is gently pressed with fingertips or a spatula or the like to be sufficiently pushed into the nail hole 5. (Fig. 3) (4) When the filling material 6 is almost dry,
Wipe off the filler 6 on the nail hole 5 by wiping from the side to one side with a cloth. (FIG. 4) In this way, each nail hole 5 is closed, and since these closed portions are scattered on the uneven decorative surface of the inner wall material, they are hardly noticeable in appearance.

In addition, the above-mentioned filling material 6 is prepared in advance. A color similar to the uneven decorative surface. Needless to say, it can be used.

(Effects of the Invention) The present invention has the above-mentioned structure, and the filler 6 coated into the nail hole 5 is made by softening a powder of the same type as the substrate of the inner wall material 1 with water. Therefore, it has good adhesion, and at the same time as it is applied, the moisture seeps into the material structure of the substrate exposed on the inner circumferential surface of the nail hole 5, and is integrally bonded with the material of the filler 6. , The filler material 6 has reached the depth of the hole.
The tip of the notch 4 of the lamp body 4 remaining in the inner wall material 1
b The tip of the nail is wrapped around it and the nail goes deep into the hole, and the part that protrudes outward from the edge of the nail hole 5 dries in a soft state and shrinks slightly, but a dense sticky part is formed. Even when wiping this part with a cloth, there is no fear that the part will come off all at once.

As described above, according to the present invention, it is possible to create a beautiful wall surface in which each nail hole is closed when covering an interior wall material using a gypsum board, a calcium silicate board, etc. as a substrate, and It has many advantages, such as the fact that filling the holes is extremely easy.
