Further, an annular ridge 25 is formed by bulging the outer peripheral edge of the through hole 24 in an annular shape along the oblong shape.
In this example, the through hole 24 has a short diameter of 13 mm and a long diameter of 20 mm, and the annular ridge 25 has a minimum thickness of 5 mm at the tip and has a rising height of 5 mm from the upper surface of the bottom wall 23. is there.

Further, reference numeral 26 in the drawing denotes a pair of reinforcing ribs provided on the side walls 21 and 22, respectively, and a pair of screw holes 27 are vertically formed on the side wall 21 between the ribs 26 on the side, that is, on the handrail A coupling side. In addition to being provided, a drain hole 28 is formed as a drain means in the upper surface position of the bottom wall 23 therebelow.

The anchor bolt 40 is a long one having an outer diameter of 10 mm and a length of 10 cm. The anchor bolt 40 is inserted and bonded into the perforation 60 of the body C so as to project above the body C. It is fixed vertically.

That is, the skeleton C is, for example, a concrete body such as a roof parapet or a rising wall of a veranda, and a downward vertical hole 60 is bored from the upper surface side at each column fixing position, and the anchor bolt is provided in the hole 60. 40 is inserted and bonded. In this example, the perforation 60 has a diameter of 18 mm at the front-rear center of the body C and is drilled so that the depth is about 8.5 cm, and the anchor bolt 40 is slightly floating. By inserting epoxy resin 61 into the voids in the perforation 60 by inserting and filling and curing it, the anchor bolt 40 is bonded and integrally bonded to the inner peripheral wall of the perforation 60 of the skeleton C so as to project 2.5 cm upward from the upper surface of the skeleton C. The above-mentioned fixation has been made as it is.

On the upper surface of the frame C, the casting holder 20 is placed at each anchor bolt 40 position, and
At the time of this placement, the tip of the anchor bolt 40 is penetrated through the through hole 24, and the upper portion of the through hole 24, that is, the annular ridge 25
It is projected upwards. In this example, the protruding length is set to a little over 1 cm.

In the mounted state of the casting holder 20, a fixing nut 50 is screwed and fastened to the tip of the anchor bolt 40 via a washer.
The upper end of the annular ridge 25 is used as a receiving position, and the annular ridge 25 is received and mounted in a clamped manner. As a result, the bottom wall 23 is sandwiched between the upper surface of the skeleton C and the fixed nut 50. The casting holder 20 is firmly and stably fixed by directly pinching it.

After the casting holder 20 is directly attached and fixed, the support column 10 is fitted into the tubular portion between the side walls 21 and 22 in a drop-like manner from above, and a fixing screw which is a Tegus screw through the screw hole 27 of the side wall 21. The columns 10 are fixed by means of 30, and vertical small beams 15 are assembled between the upper and lower beams 13, 14 by L-shaped brackets 11 between the respective columns 10 so that the upper beam 1
The handrails A formed by covering and fitting the handrail material 16 on the upper surface of the handrail 3 are fixed by interposing the handrails A in a continuous standing manner.

Numeral 29 in the figure is an EPDM which is adhesively arranged in the concave portion of the lower surface of the bottom wall 23 so as to exclude the through hole 24.
The waterproof material 29 is a cushioning waterproof material, and has a function to prevent the rainwater from penetrating into the anchor bolt 40 by compressing the fixing nut 50 with a strong pressure between the skeleton C and the casting holder 20.

Therefore, in the handrail fixing device B of this example,
Since each of the columns 10 is fitted and fixed to the casting holder 20 that is firmly and stably fixed, the column 10 and the handrail A can have excellent fixing strength with robustness and durability.

The rainwater that has entered the casting holder 20 is caused by the annular ridge 25, which causes the anchor bolt 40 to move.
To prevent rusting from being promoted, the water is appropriately discharged from the water drain hole 28, and the anchor bolt 4 is also discharged from the gap between the casting holder 20 and the skeleton C.
Prevents rainwater from reaching 0.

Instead, the casting holder 20 has a large-diameter flat shape so as to be interposed between the skeleton C and the upper slab, while the casting holder 20 has a pair of fixing side walls 21 and a bottom wall 23 of these lower surfaces. It is formed as a U-shape that is open to the upper side and both sides by means of the above, and the vertical support column 17 having a length close to the distance between the frame C and the upper floor slab is fixed to the casting holder 20 in a slide-like or tendon shape. It can be received between the side walls 21.

The casting holder 20 of this embodiment further includes a pair of rocking preventing fitting projections 31 that engage with the inside of the vertical columns 17 in the vicinity of the respective open sides to increase the fixing strength of the vertical columns 17. In addition, the drainage grooves 32 are formed on both sides of the fitting protrusions 31 as drainage means.
Since the rest is the same as the above example, the same reference numerals are given and the description thereof is omitted.

In FIG. 10, the casting holder 20 is used for a handrail A for stairs, and one end of the casting holder 20 is provided with an inclined skeleton C.
It is assumed that the support nut 51 for supporting the lower surface of the casting holder 20 is additionally screwed and fastened at an intermediate position of the anchor bolt 40 while being placed on the inclined body C in a floating manner. Then, the anchor bolt 40
An L-shaped closing member 52 for blindfolding is used to prevent the exposure of the casting holder 20, and the closing member 52 is attached to the casting holder 20 and the support nut 5.
It is designed such that it is clamped and fixed between 1 and the rest is the same as in the above example, so the same reference numerals are given and the description thereof is omitted.

In this example, the intermediate portion of the anchor bolt shaft is partially exposed, but the rainwater in this portion is well drained and air-dried.

This example can also be used for stairs or slopes in a building. In that case, the same fixing device may be used without providing drainage means, and the anchor bolts can be prevented from being exposed. In order to perform it on the outer peripheral side, it is possible to use a closing member adapted to this and cover it with a pipe such as a resin or the waterproof material.

Although the illustrated example is as described above, in the practice of the present invention, the pillar and the handrail which are integrally located in the end or the middle surface thereof are used, and the side wall of the casting holder is used. Use bolts and nuts that penetrate these as the fixing metal fittings for the columns instead of the above fixing screws, incline the bottom surface of the bottom wall, and use a wedge as well as a horizontal skeleton by using a wedge. The shape of the through hole of the casting holder should be circular, and the annular ridge should be circular, and the fin-like ridges should be provided on the outer periphery of the annular ridge to project water. Columns, vertical columns, side walls, bottom walls, through holes, annular ridges, casting holders, including water drain holes that penetrate through the bottom wall
The specific shapes, structures, materials, etc. of the skeleton perforations, anchor bolts, their bonding means, and fixing nuts can be variously modified without departing from the gist of the above invention, and are not limited to those shown and described above. Absent.

[0026]

Since the present invention is configured as described above,
This can be a handrail strut fixing device that can be directly attached to the body using a casting holder and has a good appearance and excellent fixing strength.

Further, since a casting holder having an annular raised portion in which the outer peripheral edge of the through hole at the center of the bottom wall is raised in an annular shape is provided, while the side wall or the bottom wall is provided with water draining means, the casting holder is inserted into the casting holder or the column. The rainwater entering the above-mentioned annular ridge becomes a waterproof bank, which can be smoothly drained to the outside of the casting holder. Therefore, rainwater reaches the anchor bolt at this part, and the anchor bolt rusts due to high humidity. It effectively prevents deterioration and secures the fixing strength for many years.

Further, the presence of the annular raised portion serves to receive the fixing nut at the tip of the anchor bolt, so that the screw fastening can be reliably performed.
