Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for constructing handrails for rooftop parapets, verandas of buildings, stairs or slopes, and more particularly to a handrail support fixture and a handrail support method.

[0002]

2. Description of the Related Art A handrail support fixing device or a handrail support fixing method is disclosed in Japanese Patent Publication No. Hei 6-84666 as a handrail support fixing device.
No. is known in the art.

According to this, as shown in FIG.
1 is provided with an annular raised portion 52 whose outer periphery is annularly raised, and a casting holder 50 provided with a water draining means 53 communicating with a side wall or an outer wall is provided with a through hole 51 at a tip end of an anchor bolt 54 protruding from the body. It has a structure in which a fixing nut 55 is screwed onto the anchor bolt 54 to be mounted and mounted externally.

[0004]

For this reason, when the fixing nut 55 is screwed into the anchor bolt 54, the fixing nut 55 becomes entangled with the annular projection 52 and is difficult to turn unless the anchor bolt 54 is vertically established. In addition to the constructional troubles such as the case where the annular projection 52 does not rotate and the like, the annular projection 52 itself has a problem that the design is unsightly.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has a handrail in which a fixing nut can be relatively smoothly attached and fastened to a casting holder even if an anchor bolt is erected. An object of the present invention is to provide a column fixing bracket and a handrail column fixing method.

[0006]

SUMMARY OF THE INVENTION According to the present invention, there is provided a column fixing bracket and a handrail column fixing method, in which an elongated through hole is extrapolated to an anchor bolt established in a frame and a fixing nut screwed to the anchor bolt is fastened to the frame. In the handrail support fixing bracket fixed to the base, a fixing side wall for receiving the lower end of the support is erected on the side of the bottom wall, and a fixing screw for fixing the lower end of the support is provided on at least one of the side walls, An elliptical through-hole is formed substantially at the center of the bottom wall, and the upper surface of the through-hole is formed by casting and casting an aluminum casting.The lower end of the support of the handrail is inserted and fixed with the fixing screw. It is intended to be erected.

[0007] It is another object of the present invention to form a drain structure in which a drain groove is formed in the upper surface of the bottom wall so as to communicate with a drain hole formed in the side wall.

Further, the structure in which the lower end of the support of the handrail is fixedly erected is a structure of front and rear walls which are fastened and fixed with the lower end of the support interposed therebetween. It is another object of the present invention to form a drain structure in which a drain groove which is recessed on the upper surface of the bottom wall extends in a direction without the front and rear walls.

[0009]

Embodiment 1 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. The handrail support fixture 1 is provided with a fixing side wall 3 that stands on the side of the bottom wall 2 for receiving the lower end of the support 20, and a fixing screw 8 for fixing the lower end of the support 20 on at least one of the side walls 3. Cast as an aluminum casting. An oblong through-hole 4 is formed substantially at the center of the bottom wall 2, and the upper surface of the through-hole 4 is flat.

The long through hole 4 has a short diameter of about 13 mm and a long diameter of about 20 mm. A drain groove 5 having a depth of about 3 mm is formed on the upper surface of the bottom wall 2. Handrail support fixture 1 which communicates with drain hole 6 formed in the vicinity
It communicates inside and outside. .. Are reinforcement ribs formed between the bottom wall 2 and the side wall 3, respectively. The reinforcement ribs 7 may be omitted.

The anchor bolt 10 projects from the upper surface of the frame 21 and is inserted into and adhered to a hole 22 formed in the frame 21 to be fixed vertically. The anchor bolt 10 is inserted from below into a through-hole 4 formed in the bottom wall 2 of the column fixing bracket 1, and a fixing nut 11 is screwed to an end of the anchor bolt 10 to fasten the column fixing bracket 1. The fixing nut 11 rotates on the upper surface of the flat bottom wall 2 and smoothly rotates without being caught.

That is, the frame body 21 is a concrete body such as a rooftop parapet or a rising wall of a veranda, and has a downwardly extending vertical hole 22 from the upper surface side at each column fixing position, and the anchor bolt 10 is formed in the hole 22. Insert and glue. The hole 22 is formed by drilling the frame 21 with a drill having an outer diameter of about 18 mm and a depth of 8 to 12 mm so that the anchor bolt 10 can be inserted, and filling with an epoxy resin adhesive and curing. By the frame 2
0, the anchor bolts 10 are established from the upper surface.

After the support fixture 1 is attached to the anchor bolt 10 via a washer and integrated therewith, the lower end of the support 20 is inserted into the inside of the side wall 3 of the support fixture 1, and the fixing screw 8 is fastened. The support 20 is established. By this establishment, the support fixture 1 is attached to the position where the anchor bolt 10 is set in advance, and the support 20 is established.

In the above configuration, when the fixing nut 11 is screwed and fastened, since the bottom wall 2 of the column fixing bracket 1 is configured to be smooth, the anchor bolt 10 is slightly tilted, and the anchor bolt 10 is fixed to the column fixing bracket 1. Even if not perpendicular to the bottom wall 2 of
It turns along the smooth bottom surface, and the turning is not prevented. Therefore, there is no need to worry about the vertical establishment of the anchor bolts 10 at the time of construction, and anyone can easily carry out the construction.

[0015]

Embodiment 2 Next, FIG. 4 shows a second embodiment of the present invention. That is, the fixing structure is such that the lower end of the column 20 is fastened and fixed, and the fixing screw 8 is attached to the front and rear walls 9, 9. A through-hole 3 is formed in the center of the bottom wall 2, and the upper surface of the through-hole 3 is flat.

On the upper surface of the bottom wall 2, a water draining groove 5 having a depth of about 3 mm extends in a direction without the front and rear walls 9 to constitute a water draining structure. A reinforcing rib 7 is provided between the bottom wall 2 and the front and rear walls 9.
Is constituted.

In the same manner as in the above embodiment, the handrail support fixture 1 of the above embodiment is screwed and fastened to the anchor bolt 10 with a fixing nut 11 and mounted on the frame 21, and the support column 20 is firmly fixed by the fixing screw 8. Is established.

[0018]

As described above, the handrail support fixing device and the handrail support fixing method according to the present invention extrapolate the anchor bolts established from the skeleton on the bottom wall of the member for fixing the base end of the support. When drilling the through-hole, the upper surface of the bottom wall where the through-hole is drilled is smoothed, so that even if the anchor bolt is slightly tilted and the fixing nut is inclined with the nut tightening surface, it is screwed together. It is possible to perform the work without worrying about the falling of the anchor bolt without any bearing for fastening.

Therefore, the present invention has a feature that anyone can easily carry out the work without needing any skill in establishing the handrail post, and the effect obtained by implementing the present invention is extremely large.
