Description

Anchor for nailing method and used nailing method

The invention relates to a nailing method for repairing a wall composed of a main body and decorative materials and an anchor nail for the nailing method used for the nailing method.

The nailing method refers to a method used to prevent floating parts from peeling off on decorative mortars, attached mortars, tiles and other decorative materials on exterior walls and other walls. In the nailing method, adhesives such as epoxy resin injection materials and anchors are used at the same time to integrate the main body and the decorative material.

In the past, most of the anchors used in such nailing methods are anchors that have a cone shape from the pin body to the head (for example, refer to Patent Document 1). Fig. 12 is a side view of the anchor used in the conventional nailing method. As shown in FIG. 12, the conventional anchor 100 is formed by a body 101 and a head 102. The head 102 is formed in a cone shape from the main body 101 to the head end 103. As shown in FIG. 13, the anchor 100 is inserted into the perforation 5 formed in the main body 3 through decorative materials such as mortar 4A and tile 4B, and is integrated by an adhesive 6. (Prior Art Document) (Patent Document)

Patent Document 1: Japanese Patent Application Publication No. 2007-2441 (Figure 6)

(The problem to be solved by the invention)

As shown in FIG. 14, the conventional nailing method is a structure in which the head end 103 of the anchor 100 is pressed against decorative materials such as mortar 4A and tile 4B. That is, in the conventional nailing method, the perforation 5 and the anchor 100 are only in contact with a part of the head 102 (the head end 103). The head end 103 of the anchor 100 is formed in a cone shape as described above, and because it is very thin, the support strength is not expected, and it is easily deformed when a force is applied to this part. For example, as shown in FIG. 15, when an unexpected force is applied to the tile 4B supported by the anchor 100, the thin head end 103 may be deformed and the tile 4B may fall off.

In addition, in the conventional nailing method, when the anchor 100 is inserted obliquely with respect to the perforation 5 as shown in FIG. 16, the head end 103 of the anchor 100 and the surface of the tile 4B do not form the same surface. The surface of 4B may cause unevenness. In this case, since the surface of the tile 4B must be corrected, there is a problem that it takes time for construction. There is also a problem that the appearance of the unevenness correction deteriorates due to the skill of the operator.

Therefore, the object of the present invention is to provide a nailing method and an anchor for the nailing method used therein, where even if the anchor is inserted obliquely with respect to the perforation, the size of the anchor head and the opening edge of the perforation can be maintained. The contact area also increases the supporting strength of the decorative material with the aid of anchor nails. (Means used to solve the problem)

The nailing method of the present invention is a nailing method for repairing a wall composed of a main body and a decorative material. It includes: forming a perforation on the main body through the decorative material, forming a spherical belt-shaped chamfer on the edge of the perforated opening, The adhesive is injected into the head, and the anchor with the spherical surface in contact with the spherical chamfered portion is inserted into the hole in which the adhesive is injected, so that the spherical surface of the anchor head is in contact with the hole of the hole. The ball-shaped chamfer is in surface contact.

According to the nailing method of the present invention, since the ball-belt-shaped surface of the anchor head and the ball-belt-shaped chamfered portion of the perforation form surface contact, even if the anchor is inserted obliquely with respect to the perforation, it is possible to maintain the anchor head and Large contact area at the edge of the perforated opening. (Inventive effect)

According to the present invention, since the ball-belt-shaped surface of the anchor head and the ball-belt-shaped chamfered portion of the perforation form surface contact, even if the anchor is inserted obliquely with respect to the perforation, the anchor head and the opening edge of the perforation can be maintained The large contact area of the upper part can improve the supporting strength of the decorative material by means of the anchor.

Then, as shown in Fig. 3(B), insert the anchor 1 into the deep part of the perforation 5. As a result, as shown in FIG. 3(C), the spherical belt-shaped surface 11B of the head 11 of the anchor 1 is in surface contact with the spherical belt-shaped chamfered portion 5B of the perforation 5, and the decorative material 4 passes through a larger portion than the anchor 1 The surface is supported.

Finally, the gap between the end surface 11A of the head 11 of the anchor 1 and the surface 4C of the decoration material 4 is filled with putty 8 and decorated with a touch-up paint of the same color as the surface 4C of the decoration material 4. In addition, it is preferable to wipe the putty 8 in the form of mayonnaise into the voids for construction. In addition, the putty 8 preferably adopts an ultraviolet curing type and a light curing type.

In addition, the depth D5 of the aforementioned perforation 5 is set to a depth when the anchor 1 is inserted into the perforation 5 and the spherical belt-shaped surface 11B of the head 11 of the anchor 1 and the spherical belt-shaped chamfer 5B of the perforation 5 are in surface contact , The entire body 10 is contained in the through hole 5. In addition, the depth D7 of the chamfer is set to a depth at which a gap is formed between the end surface 11A of the head 11 and the surface 4C of the decoration material 4 and the head 11 can be filled with putty 8.

As above, according to the anchoring method of the anchor 1 in this embodiment, the spherical belt-shaped surface 11B of the head 11 of the anchor 1 and the spherical belt-shaped chamfered portion 5B of the perforation 5 are in surface contact, which is caused by the larger one than the anchor 1 The surface supports the decorative material 4, so the support strength is improved. In addition, in this nailing method, even if the anchor 1 is inserted obliquely with respect to the axis 5C of the perforation 5 as shown in FIG. 5, the spherical belt-like surface 11B of the head 11 of the anchor 1 and the spherical belt-like chamfering of the perforation 5 The state of surface contact of the portion 5B is also maintained. Therefore, a large contact area between the head 11 of the anchor 1 and the opening edge of the through hole 5 can be maintained, and the supporting strength of the decorative material 4 by the anchor 1 can be maintained.
