Description

Description: TECHNICAL FIELD The present invention relates to a device for mounting a handrail support around a balcony, rooftop, etc., stairs, corridor, etc., and particularly uses a headstock having a draining slope below. It is an attachment device of a pillar for a handrail of a type.

[Conventional technology]

Handrails attached to balconies, rooftops, etc. depend on a plurality of handrail columns that are upright and fixed to the structure of the building, and there are various attachment devices for such handrail columns to the building frame. A device has been proposed and is in use.

These railing strut mounting devices are roughly divided into two types: one anchor bolt of approximately the same length as the handrail strut is fixed on the body, and the handrail strut is fixed to the body using this anchor bolt. And a steel plate called a base plate is fixed on the skeleton, and a relatively short anchor bolt fixed upright on this base plate has an outer peripheral portion that is in contact with the inner peripheral portion of the handrail support column and is called a short core metal. After fixing the support pillar and fitting the handrail support pillar to the core metal, use a screw from the outside of the handrail support pillar to fix the handrail support pillar to the core metal and hold the handrail support pillar on the body. is there.

[Problems to be Solved by the Invention]

In these known methods of mounting a handrail support column, the method of using a long anchor bolt has a relatively simple mounting device, but since it depends on one anchor bolt, it is apt to rattle during use after mounting, and has a high strength. I have a problem.

On the other hand, the method of using the core bar allows the handrail support to be fixed to the body relatively firmly, but the mounting device is complicated and the construction requires time, and it is difficult to adjust the mounting position of the core bar. However, if there is a slight misalignment, there is a lot of problems in construction such that the handrail support pillar cannot be externally fitted and fixed to the cored bar.

In view of such a current situation, the present invention is a mounting method for a handrail prop that can easily and accurately install a handrail propeller without requiring a high degree of precision in the components that make up the handrail prop. The purpose is to provide a device.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, an attachment device for a handrail support pole of the present invention is an anchor bolt that is hung vertically on a body, a pedestal that is fitted to the anchor bolt and is mounted on the body, and a drainage sloped surface. Has a through hole through which the anchor bolt is fitted, and a slanted upper surface that forms a horizontal upper surface by placing it on a draining slope of the above shed, and the anchor bolt is fitted in the central portion. An elliptical elongated hole for mounting is provided, and positioning protrusions also serving as rotation stoppers are formed at opposing portions of convex surfaces provided in a cross shape along the peripheral portion of the elongated hole, and are arranged in the cross shape. A base plate formed in an arc shape so that the tip end surface of the convex surface is located on the circumference drawn around the center of the long hole, and an elliptical long hole having a sectional shape provided in the base plate and a peripheral portion of the long hole. Cross Of the elliptical pipe member having an inner diameter corresponding to the long hole of the base plate so as to have the same outer shape as the convex surface of the base plate. A hollow bar, which is integrally formed so that each arcuate surface is located on a circle drawn with the center of the pipe member as the center, and a cored bar member having a cross-section of a cross-shaped deformed pipe. It is composed of a nut screwed with the anchor bolt, and a hollow handrail support column having a cross-section whose lower end surface abuts the upper surface of the base plate and whose inner peripheral wall is in contact with the arcuate surface of each protrusion of the cored bar member. It is what is done.

[Action]

The handrail support of the present invention uses a headstock having a draining slope surface as a lower horizontal rail forming the handrail,
The greatest feature lies in the structure of the base plate and the core metal member that abuts on the base plate.

That is, the base plate used for attaching the handrail support has an inclined upper surface that forms a horizontal upper surface by placing it on the draining slope surface of the head tree to be used, and the anchor bolt is fitted in the central portion. An elliptical elongated hole for mounting is provided, and positioning protrusions also serving as rotation stoppers are formed at opposing portions of convex surfaces provided in a cross shape along the peripheral portion of the elongated hole, and are arranged in the cross shape. The tip end surface of the convex surface is formed in an arc shape so as to be located on the circumference drawn around the center of the elongated hole, and the core metal member held on this base plate is hollow and the cross-sectional shape is provided on the base plate. Since it has a cross shape having the same shape as that of the elliptical long hole and the cross-shaped convex surface formed on the peripheral portion of the long hole, an anchor bolt is hung vertically on the frame, and the anchor bolt is attached to the anchor bolt and the bait. When the plate is externally fitted and placed on the body, the upper surface of the base plate is always kept horizontal, and at the same time, the oblong hole of the core metal member is aligned with the elliptical oblong hole formed in the base plate to match the base plate. The cored bar member can be held vertically on top.

Also, the nut is tightened by screwing the nut through the washer to the tip of the anchor bolt protruding from the tip surface of the core metal member, and then the core metal member is fixed on the body. The gold member is prevented from rotating in the circular direction by the positioning projection formed on the convex surface of the base plate, but the engagement between the projection and the protruding portion of the core metal member is in a loose fit state, so that the core metal on the base plate The member can be moved slightly back and forth, left and right and in the circumferential direction,
This allows a slight position adjustment.

When the cored bar member is fixed on the base plate, the handrail support is externally fitted to the cored bar member, and the both are fixed by screws. When the handrail supporter is externally fitted to the cored bar member, the handrail support is used. The inner peripheral surface of the support column is pressed into contact with the respective protruding portions of the core metal member until the lower end surface thereof contacts the upper surface of the base plate.

At that time, since the tip of each protruding portion of the cored bar member is an arcuate surface located on the same circumference, the contact is in a point contact state, so that the outer fitting operation can be performed smoothly, and
Since it can be moved in the circumferential direction, the mounting position can be easily corrected.
