[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 to FIG. 11 show a wall plate attachment auxiliary material 10 and a method of attaching the same according to a first embodiment of the present invention. The wall plate attachment auxiliary member 10 has an auxiliary member 14 to be in contact with the back side of the wall 12 and a fixing member 16 for fixing the auxiliary member 14 to the wall.

The assisting tool 14 has a plate 18 formed of nylon or another synthetic resin having an appropriate elasticity, and the plate 18 is formed in a C shape in which a part of a ring is broken. From the center of the broken portion of the plate 18
A folding line 20 is provided along a direction rotated by about 135 ° about the center of the rotation as a rotation center. As shown in FIG. 10, the fold line 20 is formed by a thin portion in which the surface of the plate 18 is cut out at about 90 °. The projecting piece 2 which is a connecting portion is provided at two places around the edge of a substantially circular space provided at the center of the plate member 18.
2 are formed integrally or separately. The protruding piece 22 protrudes substantially perpendicularly to the plate 18, and the protruding piece 22
The fine concavities and convexities 24 which are the engaging portions
Are continuously formed.

The fixing member 16 is an annular member formed of a synthetic resin such as nylon, and has a shallow cylindrical body 26.
One end 28 has a flange 30 as a protrusion formed on the entire side surface at a position above the end 28 in FIG.
Is provided. As shown in FIG.
Two projecting piece passages 32, which are mounting portions through which the projecting pieces 22 are inserted, are provided at two places, penetrating the other end 31 and the end 28. The inner wall of the projecting piece passage 32 has an end from the end 31 side. Part 2
A protrusion 34 protruding toward the 8 side is formed, and a protrusion / recess 36 as an engaged portion is formed on a side surface of the protrusion 34, and is provided so as to be able to engage with the protrusion / recess 24.

In the method of mounting the wall plate mounting aid 10 on the wall 12 according to this embodiment, first, a circular through hole 38 is formed at a predetermined position of the wall 12 formed of a gypsum board or the like by any means. Then, as shown in FIG. 2, the plate material 18 is easily inserted by pushing it into the through hole 38 from one end and breaking the fold line 20. At this time, the protruding piece 22 is appropriately bent and inserted through the through hole 38 to the outside, so that the insertion of the plate 18 does not become a hindrance. When the plate 18 completely enters the back side of the wall 12, the folding line 20 naturally opens horizontally by elasticity, and the plate 18
To its original shape.

Next, the tip of the protruding piece 22 projecting to the front side of the wall 12 is pulled, and the plate 18 is brought into contact with the back surface of the wall around the through hole 38. Then, as shown in FIG. 3, the protruding pieces 22 are inserted into the protruding piece passages 32 from the end 31 side of the fixture 16, respectively.
The fixing tool 16 is pressed while pulling the protruding piece 22 to bring the fixing tool 16 into contact with the wall 12 as shown in FIG. At this time, the projection 34 in the projecting piece passage 32 is elastically deformed when the projecting piece 22 is inserted from the end 31 and does not hinder the insertion. Is elastically deformed toward the protruding piece 22 and is locked so that the unevenness 36 does not fit into the unevenness 24 and does not come off.

Next, as shown in FIG. 5, the tip of the protruding piece 22 is passed through the center of the cylindrical body 26 to be brought out to the back side of the wall 12, and
The handrail bracket 40 is attached to the front side of the
Fix with. At this time, the wood screw 42 is fixed to the plate 18 with the wall 12 interposed therebetween, as shown in FIG. In addition, wood screw 4
When the screw 2 is screwed, the plate 18 is pushed in a direction away from the wall 12, but since the protruding piece 22 is securely held by the fixture 16, the wood screw 42 is easily removed without separating the plate 18 from the wall 12. Is screwed to the wall 12 and the plate 18.

The space at the center of the plate 18 is
The diameter of the plate 18 is set to be slightly smaller than the diameter of the through-hole 38 so that the plate 18 can be inserted into the through-hole 38. For this reason, the entire diameter of the plate 18 is formed to be less than three times the diameter of the through hole 38.

According to the auxiliary member 10 of this embodiment, a reinforcing material is formed on the back side of the weak wall 12 such as a gypsum board by a simple method, and the handrail bracket 40 and the like can be securely attached. . Since the through hole 38 is formed in the wall 12 and the auxiliary tool 12 is simply attached thereto with the fixing tool 16, the auxiliary tool 12 can be attached to an arbitrary position on the wall 12, and a large-scale construction is unnecessary and the cost is low. It does not use special screws for gypsum board and does not require specialized skills. Since the plate 18 is in contact with almost the entire circumference of the through hole 38, even if a plurality of wood screws 42 are used around the through hole 38, the wood screws 42 are securely fixed to the plate 18, which is safe. The protruding piece 22 has the unevenness 2 continuously.
Since it is formed, it can be attached to a wall of any thickness without any gap. Since the concaves and convexes 36 and 24 are securely locked to each other, the wooden member 42 does not rattle when a force is applied in a direction away from the wall when the wood screw 42 is attached.

Next, an auxiliary member for a wall plate attachment according to a second embodiment of the present invention will be described with reference to FIGS. Here, the same members as those in the above embodiment are denoted by the same reference numerals, and description thereof will be omitted.

The inner protrusion 34 is elastically deformed when the projecting piece 22 is inserted from the end 31 and does not hinder the insertion. When the projecting piece 22 is to be pulled toward the end 31, the protrusion 34 is elastically moved toward the projecting piece 22. It is deformed and locked so that the irregularities 36 do not fit into and engage with the irregularities 24.

Next, the tip of the protruding piece 22 is passed through the center of the cylindrical body 26 to be brought out to the back side of the wall 12, and a handrail bracket or the like is fixed to the front side of the wall 12 with a wood screw. At this time, the wood screw is fixed to the plate 54 with the wall 12 interposed therebetween. When the wood screw is screwed, the plate 54 is pushed away from the wall 12 by the tip of the wood screw, but the protruding piece 22 is securely held by the fixture 16, and the plate 54 is held by the holding member 60 in the concave groove 56.
And the plate member 54 is not broken with the concave groove 56 inside. Therefore, the wood screw is easily screwed into the plate 54 via the wall 12 without separating the plate 54 from the wall 12.

According to the auxiliary member 50 of this embodiment, a reinforcing material is formed on the back side of the weak wall 12 such as a gypsum board by a simple method, so that the handrail bracket or the like can be securely attached. In particular, the plate 54 is circular and the wall 12
Can be screwed at any position on the periphery of the through hole 38.
