Abstract

PROBLEM TO BE SOLVED: To mount firmly a mounting disk by providing the mounting disk having a through hole in the center and an engaging screw groove in the periphery and a fastening bolt having the tip passed through the through hole and threadingly engaged with a nut. SOLUTION: A tubular valve body 12 is forced inside an outside cylindrical body from the bulging part 13 side to prevent slipping-out. A nut 6 is inserted in the wall thickness part 5 of the outside cylindrical body and covered with a holed cap 7. Then, the depth side end 8a of a pack 8 is sandwiched between the wall thickness part 5 and holed cap 7 and fixed with adhesives. Next, when a fastening bolt 24 inserted into a through hole 23 of a mounting disk 22 is inserted into a cylindrical rotary valve body 12 to be screwed in a nut 6 and fastened thereto, the mounting disk is completely fixed, so that a handrail rod 25 overlaps the mounting disk to be mounted thereto by an embracing fitting 26. Then, since the wall thickness part 5 receiving the nut 6 is completely fixed with a cured filler 27, a wall body is not damaged no matter how hard the fastening bolt 24 is fastened up.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting disk mounted on a wall surface.

[0002]

2. Description of the Related Art Conventionally known Japanese Patent Publication No. 4-24569 discloses a through hole b formed in a wall a, and a cylinder c inserted from the outside of the through hole b, as shown in FIG. A screw groove formed on the inner surface of the cylindrical body c, a bag body d fixed to the outer periphery of the distal end of the cylindrical body c, and a rod body e inserted into the cylindrical body d. An anchor that injects a curable adhesive f to make the bag d larger than the through hole b is described.
Anchor Anchor means "anchor" and anchor bolt means a bolt to be embedded in concrete that is the foundation of a building. Therefore, what is described in the above publication is recognized as a so-called anchor bolt.

[0003]

However, the anchor described in the above publication is an invention relating to a bolt or a rod body embedded in a wall body, for example, an "attachment" for attaching a grip rod provided in a bathroom or a sink. It cannot be used for tightening bolts that attach a "disk". That is, in the above-mentioned known example, the bag body d is greatly inflated by injecting the adhesive f into the cylindrical body d by using the adhesive injection tool, but if the bag body d is greatly inflated, the bag body d becomes the wall body. Although it can be fixed to the inside of a, the cylinder c is not so firmly fixed to the wall a because it is only bonded to a part of the adhesive f. Since the rod e is not sufficiently fixed only by screwing it into the cylinder c, the tip g of the rod e is inserted up to the center of the spherical adhesive f and the rod is directly attached to the adhesive f. The body e is fixed. However, such a fixing method of the rod e not only cannot attach the "mounting disc 22" illustrated in FIG. 5 of the present application by the rod e, but also depends on the feeling and is about this position. Since it was inserted, it could fail and lacked certainty. Further, the adhesive f is injected into the cylindrical body c to inflate the bag d largely, but since there is no check valve, there is a problem that the injected adhesive f leaks, which makes it difficult to use.

At this time, since the thick portion 5 accommodating the nut 6 does not move even if the solidified filling material 27 is struck, the wall body 1 is not damaged no matter how strongly the tightening bolt 24 is tightened.

[0015]

As described above, the anchor described in the above publication is an invention relating to a bolt or a rod body to be embedded in a wall body. For example, "an attachment for attaching a grip rod provided in a bathroom or a sink" It cannot be used for tightening bolts that attach "discs". That is, in the above-mentioned known example, the bag body d is greatly inflated by injecting the adhesive f into the tubular body d using the adhesive injection tool, but if the bag body d is greatly inflated, the bag body d
Can be fixed to the inside of the wall a, but since the cylinder c is only adhered to a part of the adhesive f, it is not firmly fixed to the wall a. Since the rod e is not sufficiently fixed only by screwing it into the cylinder c, the rod e
The tip g is inserted up to the center of the spherical adhesive f and the rod e is directly fixed to the adhesive f. However, such a fixing method of the rod e not only cannot attach the "mounting disc 22" illustrated in FIG. 5 of the present application by the rod e, but also depends on the feeling and is about this position. Since it was inserted, it could fail and lacked certainty.
Further, the adhesive f is injected into the cylindrical body c to inflate the bag d largely, but since there is no check valve, there is a problem that the injected adhesive f leaks, which makes it difficult to use. However, according to the present invention, the through hole 2 perforated in the wall body 1, the outer cylindrical body 4 formed from a hard synthetic resin material, metal or the like inserted from the outside of the through hole 2, and the outer cylindrical body 4 are provided. A nut 6 fixedly accommodated on the tip side, a back end 8a of the pack 8 fixed on the outer periphery of the tip of the outer tubular body 4, and a filling port 9 formed at an intermediate position in the longitudinal direction of the outer tubular body 4. And a base-side end portion 8b of the pack 8 attached to the outer periphery of the outer tubular body 4 on the base side,

There is a through hole 23 in the center that abuts to the outside, and there is an engaging screw groove 2 in the periphery.
A mounting disc 22 having a mounting disc 22 and a mounting disc 22 to be mounted on the wall surface, which is formed by screwing the tip of the mounting disc 22 through the through hole 23 into the nut 6 to fix the mounting disc 22. Therefore, a, unlike the fixing of the rod body of the anchor bolt of the above-mentioned known example, the mounting disk 22 can be fixed to the outer surface of the wall body. In the above-mentioned publicly known example, the rod body of the anchor bolt is merely fixed to the wall surface, and the mounting disk 22 having the engaging screw groove 28 on the periphery cannot be fixed to the wall surface. Since the tightening bolt 24 is screwed into the nut 6 fixed at a predetermined position, the mounting disk 22 having the engaging screw groove 28 on the periphery can be fixed to the wall surface. Therefore, the handrail rod 25 and the like can be firmly attached to the attachment disk 22 that is firmly attached, and the whole is made solid. (B) In the known example, the adhesive 27 may flow back, which is not easy to handle. However, the present application has the opening / closing port 15 for opening / closing the filling port 9 so that backflow is prevented and the handling is easy. is there.
