The nut 42 is rotatably attached to the bracket 41 by screwing the screws 43a.

The handrail 20 to which the nut 42 is attached as described above is connected to the screw 44a of the mounting seat 44 by the screw 42a of the nut 42.
The handrail is fixed to the wall surface by screwing and attaching to a.

When the handrail 20 is attached to the wall by such means, the handrail 20 is fixed to the wall only by tightening the bolts 46, and there is a problem in the strength after the attachment.

Generally, when a handrail or the like is attached to a wall, it is attached to an interior part (plated portion) of a building such as a house, and the thickness of the wall is as thin as, for example, about 10 mm. There is a drawback that sufficient strength cannot be obtained to make a hole of the same size and fix with a bolt.

[0006] As another means for attaching a handrail or the like to a wall or the like, a fixing bracket of Japanese Patent Application No. 10-165861 developed by the present applicant can be used.

The fixing bracket has a structure as shown in FIG. 10. Reference numeral 51 denotes a fixing bracket main body. A space 51a is formed in a central portion and has a cylindrical shape and penetrates from the upper part to the lower part in the figure. And a recessed portion 51b provided in the recess.
Further, fastening members 52 and 53 are provided with two holding plates
A part thereof is attached to the space 51a while being rotatably held by the pins 56 and 57 on the pins 4 and 55, respectively. Reference numeral 58 denotes a spring, both ends of which are hung on the fastening members 52 and 53, respectively.
As a result, a force is exerted such that the ends of the both fastening members (the side of the space 51a) open from each other. Reference numeral 59 denotes a screw. 60
Is a fastening member receiving portion, 61 and 62 are flat washers, and these fastening member receiving portion 60 and flat washers 61 and 62 are bolts 6.
3 is fixed to a wall or the like. A pipe 72 is fixed to a pipe mounting portion 71 of the main body 51 via a packing 73. Reference numeral 90 denotes a cap, which is a space portion 5
1a is fitted into the upper opening.

Reference numeral 80 denotes another main body having a fastening member receiving portion 81 and a pipe attaching portion 82. A pipe 83 is attached to the pipe attaching portion 82 via a packing 84.

FIG. 11 shows a state where the fixing bracket main body is assembled. However, in this figure, FIG.
Is not a simple cap, but a cap having a fastening member receiving portion 91 is used similarly to the main body 80 for attaching the handrail 83, and a pipe (handrail) 72 and the like are shown in the fixing bracket main body 51. Although not shown, a pipe 72 is actually attached.

When using this fixing bracket, the fastening member receiving portion 60 is attached to the wall using the bolt 63 as described above. After that, when the fixing metal body 51 is fitted from above in the drawing and the cap 90 is further inserted into it, the state shown in FIG. 11 is obtained. When an upward force acts on the fixture body 51 in this state, the corners of the fastening member 52 engage with the slope A of the fastening member receiving portion 60 fixed to the wall, respectively.
There is no escape. When a force acts on the cap 90 upward, the slope B of the fastening member receiving portion 91 and the fastening member 53 are removed.
The cap does not come off because it engages.

In the case where a handrail or the like is attached using such a fixing bracket, the fastening member receiving portion 60 is provided with a bolt 63.
There is a problem in the strength of the wall because it is only fixed at

[0012]

When a handrail or the like is attached to a wall using the means shown in FIG. 8 or FIG.
In each case, a hole is made in the wall plate, and the wall plate is tightened with bolts and fixed.

Therefore, there is a disadvantage that the strength of the portion of the wall plate where the hole is formed, that is, the portion where the handrail or the like is attached is weakened.

The present invention has been made in order to solve the above-mentioned drawbacks, and is intended to supplement the strength of a portion where a hole has been made. The present invention provides a reinforcing member that enables sufficient reinforcement.

[0015]

A reinforcing member according to the present invention includes a reinforcing bar (generally provided at a plurality of equal intervals) mounted on the outer peripheral surface of a mounting nut so as to be openable and closable toward the periphery of the nut. A reinforcing member having a spring member acting in the opening direction, and a fixing seat fixed to the wall, and the reinforcing portion including the mounting nut, the reinforcing bar, and the spring member is closed with the reinforcing bar closed. Insert through the hole in the wall,
By inserting the reinforcing portion, the reinforcing bar is opened by the force of the spring on the side opposite to the insertion side of the wall so that it comes into contact with the surface on the opposite side, and the fixing seat is fixed to the hole in the wall, and further mounted. A bolt used to attach a pipe (handrail) or the like by screwing into the nut is inserted from a fixed seat, screwed into the mounting nut, and tightened and fixed.

Thus, the reinforcing bar of the reinforcing member of the present invention is pressed against the surface on the opposite side of the wall, thereby having a reinforcing action.

Here, if a plurality of reinforcing bars are used and arranged at equal intervals, sufficient reinforcement is possible and even reinforcement is possible.

[0018]

Next, an embodiment of the present invention will be described.

FIG. 1 is a view showing a state in which a handrail is attached using the reinforcing member of the present invention, FIG. 2 is a view showing the configuration of the reinforcing member of the present invention, (A) is an exploded perspective view, and (B) is an exploded perspective view. It is a figure showing the state where it was assembled.

As shown in FIG. 2A, the reinforcing member of the present invention comprises a reinforcing bar 1, a mounting nut 2, a fixed seat 3, a spring member 4, and a mounting rod 5, and (B).

FIGS. 3, 4, 5, 6 and 7 are views showing an operation (attachment procedure) for attaching the reinforcing member of the present invention to a wall.

First, as shown in FIG. 3, a hole 10a is formed in a wall 10 to which a handrail or the like is to be mounted, and a reinforcing member is inserted into the hole 10a by using a mounting rod 5 as shown in FIG. As the second step of the procedure, when the reinforcing member is sufficiently inserted, the reinforcing bar 1 and the like are inserted to the outside of the wall 10 as shown in FIG. Attach to 10. As a third step of the procedure, the mounting bar 5 is pulled forward (in the direction of the arrow) as shown in FIG. 5, and as a fourth step of the procedure, as shown in FIG. ). Here, the fixed seat 3 is turned and the screw 3a of the fixed seat 3 and the other screw 2b of the mounting nut 2 are turned.
Thus, the mounting nut 2 and the fixed seat 3 are connected. Thereafter, as a fifth step of the procedure, the mounting rod 5 mounted on the screw 2a of the mounting nut 2 is removed. After the mounting rod 5 is removed, a projection (minus screwdriver) 5b provided on the opposite side of the mounting rod 5 from the screw 5a is fitted with a groove 3b formed in the fixed seat 3, and the mounting rod 5 is used. Then, the mounting nut 2 is sufficiently fastened to the fixing seat 3 so that both are securely fixed. Thereby, the reinforcing member of the present invention is fixed to the wall 10 as shown in FIG.

In this manner, for example, the fastening member receiving portion 60 of the fixing bracket shown in FIG. 10 is fixed to the reinforcing member of the present invention fixed to the wall 10 by using the bolt. In other words, the fastening member receiving portion 60 of the above-mentioned fixing bracket, the flat washers 61, 6

Here, if the main body 51 of the fixing bracket is fitted and fixed, the handrail is attached to the wall 10 as shown in FIG.

In FIG. 1, the interval t between the wall 10 on which the reinforcing member of the present invention is mounted and the inner wall 11 are different, and when the length t is smaller than the length of the reinforcing bar, the reinforcing bar is inserted. Can not do. Therefore, it is desirable to prepare reinforcing members having different lengths of the reinforcing bars, and to selectively use them according to the length t. In this case, reinforcement is possible even with a reinforcement member of a short reinforcement bar. When a reinforcing member having a reinforcing bar having the most desirable length is used, and the length t is smaller than the reinforcing bar, the reinforcing bar may be cut to an appropriate length for use.

The wall 10 has a thickness of, for example, 5 mm to 2 mm.
Various types having a length of 5 mm are used. Therefore, it is necessary to use the fixing seat 3 having an appropriate length of the screw 3a according to the thickness of the fixing seat 3 depending on the plate thickness. As shown in FIG. 8, the screws of the fixed seat 3 are divided into two or three screws 3B and 3C at the tip of a normal screw 3A of, for example, about 10 mm (length 1).

It is also possible to cut and use 3C.

Here, since the reinforcing bar of the reinforcing member of the present invention is pressure-bonded to the wall 10 in a state where the reinforcing bar is opened on the surface of the wall 10 opposite to the surface on which the handrail is attached, sufficient sufficient pressure is applied to the wall 10. A reinforcing effect is obtained. Moreover, as shown in FIG. 2, the eight reinforcing bars are arranged at substantially equal intervals and are pressed against the wall, so that the wall is reinforced relatively evenly over a wide area around the hole.

The number of reinforcing bars is not limited to eight, but the larger the number, the greater the reinforcing effect. Therefore, an appropriate reinforcing effect can be obtained according to the thickness of the wall.

FIG. 1 shows a case where a handrail or the like is attached to a wall using the fixed metal shown in FIG. 10. For example, the reinforcing member of the present invention is also used when attaching a handrail or the like by means shown in FIG. be able to.

That is, in FIG. 9, when the mounting seat 44 and the packing 45 are mounted on the wall with the bolts 46, the reinforcing members of the present invention are mounted on the wall, and then the bolts 46 are screwed onto the nuts 2 to thereby achieve the present invention. The reinforcing member, the mounting seat 44 and the like are integrally mounted, and the nut 44 having the handrail 20 or the like combined with the screw 44a of the mounting seat is screwed together so that the reinforcing member of the present invention and the mounting seat 44 are integrated. The reinforcing effect can be obtained by attaching to the.

The reinforcing member of the present invention can be applied to all cases where a handrail or the like is generally fixed to a wall using bolts, in addition to the above-described two means for attaching a handrail or the like. Is possible.
