Description

Nailing method and anchor for nailing method used therefor

Technical Field

The present invention relates to a method of fixing a wall body made of a main body and a decorative material and an anchor for fixing the wall body.

Background

The nailing method is a method for preventing a floating portion from peeling off from a wall body such as an outer wall or a decorative material such as a sticking mortar or a tile. In the nailing method, an adhesive such as an epoxy resin injection material and an anchor are used together to integrate the main body and the decorative material.

Conventionally, many anchors used in such a nailing method are those in which the head part of the anchor is tapered from the pin body (see, for example, patent document 1). Fig. 12 is a side view of an anchor used in a conventional nailing method. As shown in fig. 12, a conventional anchor 100 is formed of a body 101 and a head 102. The head 102 is formed in a cone shape from the body 101 to a head end 103. Anchor 100 is inserted through a through hole 5 formed in main body 3 through a finishing material such as adhesive mortar 4A and tile 4B as shown in fig. 13, and is integrated by adhesive 6.

Problems to be solved by the invention

As shown in fig. 14, the conventional nailing method is a structure in which a head end portion 103 of an anchor 100 is pressed against a decorative material such as an adhesive mortar 4A and a tile 4B. That is, in the conventional nailing method, the penetration hole 5 and the anchor 100 are in contact only at a part (head end portion 103) of the head 102. Since the head end 103 of the anchor 100 is formed in a tapered shape as described above and is very thin, the support strength is not preferable, and the portion is easily deformed when a force is applied. For example, as shown in fig. 15, in the case where an unexpected force is applied to the tile 4B supported by the anchor 100, there is a fear that the thin head end portion 103 may be deformed and cause the tile 4B to fall off.

In addition, in the conventional nailing method, when the anchor 100 is inserted obliquely with respect to the pierced hole 5 as shown in fig. 16, the head end portion 103 of the anchor 100 is not formed flush with the surface of the tile 4B, and unevenness may be caused on the surface of the tile 4B. In this case, since the surface of the tile 4B must be corrected, there is a problem in that the construction time is consumed. There is also a problem that the unevenness correction deteriorates the appearance due to the skill of the operator.

Accordingly, an object of the present invention is to provide a method of anchoring and an anchor for anchoring used in the method, in which even if the anchor is inserted obliquely with respect to a pierced hole, a large contact area of an anchor head with an opening edge portion of the pierced hole is maintained and a supporting strength of a finishing material by the anchor is improved.

Means for solving the problems

The nailing method of the invention is a nailing method for repairing a wall body composed of a main body and a decorative material, and comprises the following steps: a piercing hole is formed in the body so as to penetrate the decorative material, a spherical fillet is formed at the edge of the opening of the piercing hole, an adhesive is injected into the piercing hole, an anchor having a spherical fillet surface at the head in surface contact with the spherical fillet surface is inserted into the piercing hole in which the adhesive is injected, and the spherical fillet surface at the head of the anchor is brought into surface contact with the spherical fillet surface of the piercing hole.

According to the nailing method of the present invention, since the spherical strip surface of the anchor head and the spherical strip chamfered portion of the penetration hole are brought into surface contact with each other, even if the anchor is obliquely inserted into the penetration hole, a large contact area between the anchor head and the opening edge portion of the penetration hole can be maintained.

Effects of the invention

According to the present invention, since the spherical strip surface of the anchor head and the spherical strip chamfered portion of the penetration hole are in surface contact with each other, even if the anchor is obliquely inserted into the penetration hole, a large contact area between the anchor head and the opening edge portion of the penetration hole can be maintained, and thus the support strength of the finishing material by the anchor can be improved.

As shown in fig. 4, the nailing method in the embodiment of the present invention is a method of forming a perforation 5 in a wall 2 such as an outer wall or an inner wall of a building at a portion to be repaired such as a portion where a body 3 floats to a decorative material 4 such as a decorative mortar (not shown), a bonding mortar 4A, a tile 4B, or the like, injecting an adhesive 6 such as an epoxy resin injection material into the perforation 5, inserting an anchor 1, and integrating the body 3 and the decorative material 4 to perform the repair.

As shown in fig. 1, an anchor 1 for nailing in the embodiment of the present invention is formed of a rod-like (cylindrical) body 10 and a spherical strip-like head 11. The body 10 and the head 11 are integrally formed of, for example, stainless steel. The diameter R10 of the body 10 is made smaller than the inner diameter R5 (see fig. 2 a) of the through-hole 5 described later. In addition, although not shown, irregularities are formed on the outer circumferential surface of the body 10 by knurling to improve tensile strength.

The head 11 has a circular end face 11A and a spherical band-shaped face 11B extending from the connection face 10A with the body 10 to the end face 11A. The connection surface 10A and the end surface 11A of the body 10 are planes perpendicular to the axis 10B of the body 10. In the present embodiment, the head 11 is a ball seat formed by cutting a sphere of diameter R11 with two parallel connection surfaces 10A and end surfaces 11A. The spherical band surface 11B is a side portion of the ball seat.

In the nailing method using the above-described anchor stud 1, as shown in fig. 2(a), first, a perforation 5 having a depth D5 is formed in the body 3 so as to penetrate the finishing material 4 at a portion to be repaired of the wall body 2 having the finishing material 4 such as the adhesive mortar 4A and the tile 4B provided on the surface of the body 3. Then, as shown in fig. 2(B), the hole 5 is chamfered by the spherical strip-shaped chamfering bit 7 from the opening edge 5A to a depth D7, and as shown in fig. 2(C), a spherical strip-shaped chamfer 5B is formed at the opening edge 5A.

Since the spherical diameter R7 of the tip of the spherical strip chamfer drill 7 is the same as the diameter R1 of the spherical strip surface 11B of the head 11 of the anchor 1 used, the inner diameter R3 of the spherical strip chamfer 5B is the same as the diameter R1 of the spherical strip surface 11B. Thus, when the anchor 1 is inserted into the pierced hole 5, the spherical strip surface 11B of the head 11 of the anchor 1 and the spherical strip chamfered portion 5B of the pierced hole 5 come into surface contact with each other.

Next, as shown in fig. 3(a), the adhesive 6 is injected into the through-holes 5, so that the adhesive 6 is spread in the through-holes 5 and on the floating portions of the decorative material 4. Then, as shown in fig. 3(B), the anchor 1 is inserted deep into the pierced hole 5. As a result, as shown in fig. 3(C), the spherical strip surface 11B of the head 11 of the anchor 1 is in surface contact with the spherical strip chamfered portion 5B of the penetration hole 5, and the finishing material 4 is supported by a surface larger than the anchor 1.

Finally, the gap between the end face 11A of the head 11 of the anchor 1 and the surface 4C of the decorative material 4 is filled with putty 8, and decorated with a color-finish paint having the same color as the surface 4C of the decorative material 4. It is preferable to apply the mayonnaise-like putty 8 by rubbing it into the gap. Further, the putty 8 is preferably of an ultraviolet curing type or a light curing type.

The depth D5 of the penetration hole 5 is set to a depth such that the entire body 10 is accommodated in the penetration hole 5 when the anchor 1 is inserted into the penetration hole 5 and the spherical strip surface 11B of the head 11 of the anchor 1 and the spherical strip chamfered portion 5B of the penetration hole 5 are brought into surface contact with each other. Further, the chamfered depth D7 is set to a depth at which a gap is formed between the end face 11A of the head portion 11 and the surface 4C of the trim material 4 and the head portion 11 can be filled with putty 8.

As described above, according to the method of fastening the anchor 1 in the present embodiment, the spherical strip surface 11B of the head 11 of the anchor 1 and the spherical strip chamfered portion 5B of the pierced hole 5 are in surface contact with each other, and the finishing material 4 is supported by a surface larger than the anchor 1, so that 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 pierced hole 5 as shown in fig. 5, the state in which the spherical strip surface 11B of the head 11 of the anchor 1 and the spherical strip chamfered portion 5B of the pierced hole 5 are in surface contact is maintained. Therefore, a large contact area between the head 11 of the anchor 1 and the opening edge portion of the penetration hole 5 can be maintained, and the support strength of the decorative material 4 by the anchor 1 can be maintained.

Next, other embodiments of the anchor of the present invention are described. Fig. 6 is a side view of an anchor according to another embodiment of the present invention, fig. 7 is a partial perspective view showing an exploded state of the anchor of fig. 6, fig. 8 is a partial side view showing a swing state of a cap of the anchor of fig. 6, fig. 9 is a vertical sectional view of fig. 8, fig. 10 is an explanatory view showing an insertion process of the anchor of fig. 6, and fig. 11 is a partial enlarged view showing a state after the anchor is inserted.

The anchor 9 shown in fig. 6 is constituted by the aforementioned anchor 1 as an anchor body and a cap 12 fitted with a spherical strip-like head 11 at the end of the anchor 1. The cap 12 forms the head of the anchor 9 in a state of being fitted to the head 11 of the anchor 1, and has a spherical strip surface 12A surface-contacting the spherical strip chamfer 5B of the penetration hole 5.

Cap 12 has a recess 12B that mates with head 11 of anchor 1. The inner surface of the recess 12B is formed into a spherical strip-shaped surface which is in surface contact with the head 11 of the anchor 1. In addition, notches 12C for enlarging the opening of the recess 12B to fit with the head 11 of the anchor 1 are formed at two places on the cap 12.

In the anchor 9, as shown in fig. 8 and 9, since the cap 12 capable of swinging is fitted to the head 11 of the anchor 1, it is possible to cope with a case where the axis 10B of the anchor 1 and the end surface 12D of the cap 12 are not orthogonal to each other, that is, a case where the pierced hole 5 into which the anchor 1 is inserted and the finishing material 4 such as the tile 4B are not orthogonal to each other.

When the anchor 9 is inserted into the pierced hole 5 into which the adhesive 6 has been injected as shown in fig. 10, the spherical strip surface 12A of the cap 12 is in surface contact with the spherical strip chamfered portion 5B of the pierced hole 5. In the anchor 9, even if the anchor 1 (anchor body) is inserted obliquely with respect to the penetration hole 5, the cap 12 can swing, so that the end surface 12D of the cap 12 can be maintained parallel to the surface 4C of the finishing material 4.

Therefore, by adjusting the depth D7 of the aforementioned chamfer so that the end face 12D of the cap 12 is formed coplanar with the surface 4C of the trim material 4, the putty 8 need not be used. In this case, the end face 12D of the cap 12 may be decorated with a color-finish paint having the same color as the surface 4C of the decorative material 4.

In addition, even in the nailing method using the aforementioned anchor 1, the end surface 11A of the head 11 of the anchor 1 is formed to be coplanar with the surface 4C of the finishing material 4 by adjusting the depth D5 of the penetration hole 5, and the putty 8 does not need to be used. In this case, the end surface 11A of the head 11 of the anchor bolt 1 may be decorated with a finish paint having the same color as the surface 4C of the decoration material 4.
