DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a temporary handrail auxiliary device mainly used when attaching a handrail to a parapet of a building.

[Conventional technology]

On rooftops and balconies of buildings, parapets for danger prevention were set up high or the rise of parapets was reduced, and handrails were attached to the parapets. When attaching a handrail to a parapet, a column hole for implanting a column of the handrail is provided in a part of the parapet, or it is disclosed in Japanese Patent Laid-Open No. Sho 62-62.
-When constructing a parapet as described in Japanese Patent No. 236955, a strut hole for the handrail is formed in advance, the lower part of the strut is inserted in this strut hole, cement is embedded in the strut hole while adjusting the inclination of the handrail, and the handrail is attached. Was there.

[Problems to be solved by the device]

There is a problem in that the handrail tilt adjustment by hand requires a high degree of skill, and there is a problem in that tilt adjustment is dangerous because the parapet is constructed on the rooftop or around the balcony.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to provide a temporary auxiliary device that can accurately and easily hold a handrail when attaching the handrail to a parapet. To do.

[Means for Solving the Problems]

In order to achieve the above object, the handrail temporary auxiliary device according to the present invention comprises a gate type fixed body that is fitted and fixed to a parapet, a pole that stands upright on the fixed body, and a handrail holding tool that is attached to the pole, and a handrail holding tool. It is composed of a C-shaped clamp that fits into the pole, a screw rod that holds the clamp horizontally, and two holding plates that are screwed into the screw rod.

[Action]

The fixed body is fixed by a pushing rod that is screwed from the inner and outer legs, the clamp of the handrail holding tool can be slid up and down along a pole standing upright from the fixed body, and the two holding plates screwed to the holding rod of the holding tool are It is possible to move back and forth individually within the range of the screw rod.

〔Example〕

Hereinafter, the structure of the handrail temporary auxiliary device according to the present invention will be described with reference to the drawings of the embodiments.
It is composed of a gate-shaped fixed body 2 having an opening larger than the wall thickness T, a pole 4 standing upright from the fixed body 2, and handrail holding tools 5, 15 attached above and below the pole 4. Among them, the fixed body 2
Is pushed into at least one of the inner leg 2a facing the indoor surface p1 of the parapet P and the outer leg 2b facing the outdoor surface p2 of the parapet P by screwing the push rod 3 that can be screwed back and forth toward the opposite leg, A push plate 13 is attached to the tip of the push rod 3 protruding inward from the legs 2a and 2b.
In addition, a turning portion 23 such as a handle or a wing nut is provided at the rear portion of the pushing rod 3 projecting outward from the inner and outer legs 2a, 2b, and the pushing rod 3 is screwed back and forth by turning the turning portion 23. .

The pole 4 is higher than the column height H of the handrail A, and its lower end is welded to the inner leg 2a of the fixed body 2.

The handrail holding tools 5 and 15 include a C-shaped clamp 8 which is fitted in the pole 4 and can slide up and down, a screw rod 6 which is horizontally held by the clamp 8, and two holding plates 7 and 17 which are screwed to the screw rod 6. The clamp 8 has a pole insertion hole 18 in the center,
Arm pieces 8a, 8b are provided at both ends relative to each other, a screw rod 6 is attached to one arm piece 8a, a through hole 28 of the screw rod 6 is bored in the other arm piece 8b, and a screw rod 6 exposed to the outside from the through hole 28 is formed. Screw nut 16 onto
Tighten the clamp 8 by tightening the nut 16 and the pole 4
Fixed to. The screw rod 6 horizontally held by the clamp 8 projects at least to the outdoor side of the parapet P, and the holding plates 7 and 17 screwed to the screw rod 6 have elastic members 7a attached to their opposing surfaces.

Since the handrail temporary auxiliary device of the present invention has the above-mentioned structure, in order to attach the handrail A to the existing parapet P using this, the post hole S of the handrail A is preliminarily formed in a part of the parapet P, and Insert the lower part of the handrail support B into the support hole S, first insert the fixed body 2 of the auxiliary device 1 of the present invention from above the parapet P, and insert the pushing rod 3 screwed into the inner leg 2a of the fixed body 2 into the parapet P.
Of the parapet P or the pushing rod 3 screwed into the outer leg 2b, or the pushing rod 3 screwed into the inner and outer legs 2a, 2b. The parapet P is screwed toward the parapet P, and the parapet P is held from inside and outside by the screwing of the pushing rod 3, and the fixed body 2 is attached to the parapet P. Then Paul 4
Loosen the clamp 8 of the upper holding tool 5 which is fitted and fixed to the upper holding tool 5, slide down the clamp 8 until the horizontally held screw rod 6 reaches the handrail headstock C, and tighten and fix the loosened clamp 8. After loosening the clamp 8 of the holding tool 15 and slidingly fixing the clamp 8 onto the lower chord member D of the handrail, the holding plates 7 and 17 screwed to the screw rod 6 horizontally held by the clamp 8 are rotated to move the holding plate. Clamping Kasagi C and lower chord material D at 7,17 and holding plate
The inclination of handrail A is corrected by the movement adjustment of 7,17 and it is held vertically.

Specifically, the handrail temporary auxiliary equipment 1 of the present invention is dispersed and attached to several places, and at least two sets of the temporary auxiliary equipment 1 are used for the handrail A.
Is to support.

After the handrail A is erected on the parapet P using the handrail temporary auxiliary device 1 of the present invention, cement is poured into the post hole S in which the lower end portion of the post B is put, and after the cement is solidified, the temporary auxiliary device 1 of the present invention is removed. is there.

FIG. 4 shows an example of use of the temporary auxiliary device 1 of the present invention in the case of attaching the handrail A to the newly constructed parapet P. First, the pillar B of the handrail A is provided inside the parapet construction formwork F.
Then, the fixed body 2 of the temporary auxiliary device 1 is fitted into the form F from above and fixed to the form F, and then the height of the holding tool 5 provided on the pole 4 standing upright from the fixed body 2 is adjusted. Then
The holding plates 7 and 17 of the screw rod 6 horizontally held by the holding tool 5 are rotated, and the handrail headstock C is held by the holding plates 7 and 17, and the handrail A is held upright. After the handrail A is erected on the form F using the handrail temporary assistance device 1 of the present invention, cement is poured into the form F and the handrail A is planted on the parapet P.

[Effect of device]

Since the handrail temporary auxiliary device of the present invention is configured as described above, it has the following effects.

Since the fixed body can be attached to the parapet, the pole is erected on this fixed body, the clamp of the handrail holding tool is inserted and fixed to the pole, and the screw rod is horizontally held by the clamp, so by the temporary handrail auxiliary device of the present invention. The handrail that is temporarily installed on the parapet can be easily supported, and the inclination of the handrail can be easily corrected by simply turning the holding plate that engages the screw rod and moving the holding plate back and forth. It can be accurately supported without requiring skill, and its handling operation is extremely simple.

Also, the clamp of the holding tool can be adjusted up and down according to the height of the handrail railing and the lower chord material, and the holding plate that is screwed into the screw rod of the holding tool can be advanced and retracted within the range of protrusion of the screw rod. It can also be widely used for mounting handrails of different types.
