  Hereinafter, the present invention will be described in detail with reference to the drawings illustrating an embodiment. FIG. 1 is an exploded explanatory view showing a handrail attachment structure showing an embodiment of the present invention, FIG. 2 is a sectional view showing male and female bushes, and FIG. 3 is an explanatory view showing an attachment procedure in the handrail attachment structure of the present invention. FIG. Here, the handrail mounting structure 10 uses a bolt 7 and a washer nut 12 arranged behind the wall panel to a wall panel 11 such as a unit bath, and the handrail is fixed to the wall panel 11. A reinforcing plate 13 is arranged behind, and the reinforcing plate 13 is temporarily fixed to the wall panel 11 with, for example, a male bush 14 and a female bush 15 that can be screwed together. A washer nut 12 is screwed with a screw 4 behind the reinforcing plate 13. The fixing flange 17 formed at the end of the handrail 16 is fixed to the washer nut 12 via the bolt 7. Note that the washer nut 12 is not necessarily fixed to the reinforcing plate 13 with a screw, and may be fixed by other known methods.

  The washer nut 12 has a screw hole 12a into which the bolt 7 is screwed in the center, and a screw hole 12b in the vicinity of the end. Further, the central region in which the screw hole 12a is formed is displaced outwardly to secure a space for accommodating a flange portion of the male bush 14 described later.

  The reinforcing plate 13 has a flat plate shape and has a mounting hole 13a through which the bushes 14 and 15 are inserted. The hole diameter H of the attachment hole 13a is formed to be larger than the outer diameter dimension h of the female bush 15, and by moving the position of the washer nut 12, an error in the hole position can be absorbed.

  The male bush 14 includes a cylindrical portion 14a and a flange portion 14b, and a male screw that engages with the female bush 15 is formed on the outer periphery of the cylindrical portion 14a. The female bush 15 includes a cylindrical portion 15a and a flange portion 15b, and a female screw is formed on the inner periphery of the cylindrical portion 15a. The male bush 14 and the female bush 15 thus formed hold the reinforcing plate 13 between the flange portions on the wall surface panel 11 by screwing. The male bush 14 and the female bush 15 can be coupled by a coupling means other than a screw, such as fitting.

  The handrail 16 is provided with a mounting flange portion 17 having a bolt hole 17a at an end portion of a hollow pipe or the like similar to a general handrail used in a bathroom. Further, the mounting flange portion 17 is covered with a cover member 18 so that the bolt 7 cannot be seen from the outside.

  A method for mounting the handrail mounting structure 10 thus configured on the wall panel 11 will be described. First, in the temporary fixing step, the reinforcing plate 13 is disposed behind the wall surface panel 11 and the female bush 15 is inserted into the mounting hole 13a of the reinforcing plate 13 from the indoor side of the mounting hole X formed in the wall surface panel 11 from the back surface side. The male bush 14 is screwed and temporarily fixed to the wall surface panel 11 by both flange portions 14b and 15b. At this time, since the hole diameter H of the mounting hole 13a is formed larger than the outer diameter dimension h of the female bush 15, an error in the hole position can be absorbed. Moreover, since the space | interval of both the flange parts 14b and 15b is decided by the screwing grade of a screw, it can respond to the thickness of a various wall surface panel, and the thickness of a reinforcement board. Further, the male bush 14 may be screwed from the indoor side of the wall panel 11 and the female bush 15 may be screwed from the back side.

  In the fixing step, the washer nut 12 is adjusted with the screw 4 after adjusting the hole position behind the reinforcing plate 13. In this step, the reinforcing plate 13 and the washer nut 12 are temporarily fixed to the back surface of the wall panel 11 and do not fall.

  In the fixing step, the bolt 7 is screwed into the washer nut 12, and the handrail 16 is fixed to the wall panel 11 via the attachment flange portion 17 formed at the handrail end. Further, the cover member 18 is attached to the handrail end.

  In the above description, the hole diameter of the attachment hole X formed in the wall surface panel 11, which describes an example in which the hole diameter H of the attachment hole 13 a of the reinforcing plate 13 is formed larger than the outer diameter dimension h of the female bush 15, Even if it is formed larger than the outer diameter dimension h of the female bush 15, an error in the hole position can be absorbed.

  In the present invention, when attaching the handrail to the wall panel, there is no possibility that the reinforcing plate and the washer nut will drop off on the back surface of the wall panel, and since the handrail can be attached after the bathtub is carried in, workability can be improved. .
