Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a device for attaching handrail supports around balconies, rooftops, etc., stairs, hallways, etc., and particularly to a device for attaching handrail supports around balconies, rooftops, etc. This is a type of handrail support mounting device.

[Conventional technology]

Handrails attached to balconies, rooftops, etc. depend on multiple handrail supports that are fixed upright to the building frame, and there are various methods for attaching these handrail supports to the building frame. A device has been proposed and is in use.

Broadly speaking, these handrail support installation devices can be broadly divided into two types: An anchor bolt of the same length as the handrail support is fixed onto the frame, and this anchor bolt is used to secure the handrail support to the structure. The method involves fixing an iron plate called a base plate on the building frame, and attaching a short support called a core metal whose outer periphery touches the inner periphery of the handrail support to a relatively short anchor bolt that is fixed upright on the base plate. After fixing the handrail post and fitting the handrail post onto the core metal, use screws from the outside of the handrail post to fix the handrail post to the core metal and hold the handrail post on one body. be.

[Problem to be solved by the invention]

Among these known handrail support mounting methods, the method of using long anchor bolts has a relatively simple mounting device, but since it relies on a single anchor bolt, the mounting is likely to become loose during subsequent use. There is a problem with strength.

On the other hand, with the method of using cored metal, although it is possible to fix the handrail support to the frame relatively firmly, the mounting device is complicated, takes time to install, and it is difficult to adjust the installation position of the cored metal. However, there were many problems in construction, such as the fact that if there was even a slight misalignment, it would be impossible to fit and fix the handrail support to the core metal.

In view of the current situation, this invention has been developed to provide a handrail support that can easily absorb some errors and be accurately attached to a container without requiring the parts that make up the handrail support to be very precise. The object of the present invention is to provide a mounting device for.

[Means to solve the problem]

In order to achieve the above object, the handrail support mounting device of the present invention comprises: an anchor bolt vertically installed on a frame; an inclined pedestal fitted onto the anchor bolt and mounted on the frame; and a drainage slope surface. A cap board having a through hole for fitting the anchor bolt into the cap board, and an inclined upper surface that forms a horizontal upper surface by being placed on a drainage slope surface of the cap board, and the anchor bolt is fitted in the center part of the cap board. An elliptical elongated hole for mounting is provided, and positioning protrusions that also serve as detents are formed on opposing parts of convex surfaces provided in a cross shape along the periphery of the elongated hole, and A base plate formed in an arc shape such that a convex tip surface is located on a circumference centered on the center of the elongated hole, an elongated hole with an elliptical cross-sectional shape formed in the base plate, and a peripheral edge of the elongated hole. An elliptical vibrator with an inner diameter that matches the elongated hole of the base plate has the same shape as the outer shape of the cross-shaped convex surface. A core metal member consisting of a deformed pipe having a cross-sectional cross-sectional shape, in which a hollow protruding portion formed as a surface is integrally provided so that each arcuate surface is located on a circumference drawn around the center of the pipe member. and a hollow handrail post having a cross section whose lower end surface abuts the upper surface of the base plate and whose inner circumferential wall contacts the arcuate surface of each protrusion of the core metal member. It consists of:

[For production]

The handrail support of the present invention uses a Kasagi having a draining slope as the lower horizontal beam constituting the handrail. be.

In other words, the base plate used to attach the handrail support to the slope of the draining slope of the Kasagi that will not be used!
! It has an inclined upper surface that forms a horizontal upper surface when the anchor bolt is placed, and an elliptical elongated hole for fitting the anchor bolt is provided in the center, and a cross-shaped hole is provided along the periphery of the elongated hole. A positioning protrusion that also serves as a rotation stopper is formed on opposing parts of the convex surface, and the distal end surface of the convex surface disposed in a cross shape is formed in an arc shape so as to be located on a circumference centered on the center of the elongated hole. The core metal member held on the base plate is hollow and has a cross-sectional shape that is the same as the outer shape of the elliptical long hole provided in the base plate and the cross-shaped convex surface formed at the periphery of the long hole. Because it is shaped like a cross, when the anchor bolt is vertically installed on the frame, and the cap and base plate are fitted onto the anchor bolt and placed on the frame, the top surface of the base plate always remains horizontal, and at the same time, the top surface of the base plate remains horizontal. By aligning the long holes of the core metal member with the formed elliptical long holes, the core metal member can be held vertically on the base plate.

In addition, a nut is screwed onto the tip of an anchor bolt protruding from the tip end surface of the core metal member through a washer, and then the nut is tightened to fix the core metal member on one body, but when tightening the nut, Although the core metal member is prevented from rotating in the circular direction by the positioning protrusion formed on the convex surface of the base plate, since the protrusion and the protrusion of the core metal member are loosely fitted, the core member does not rotate on the base plate. The metal member can be moved slightly in the front, back, left, right, and circumferential directions.
This allows for some positional adjustment.

When the core metal member is fixed on the base plate, the handrail support is fitted onto the core metal member and the two are fixed with screws. The inner circumferential surface of the column is pressed into contact with each protrusion of the core member until its lower end surface contacts the upper surface of the base plate.

At this time, since the tips of each protruding part of the core metal member are arcuate surfaces located on the same circumference, the contact is in a point contact state, so that the external fitting operation can be performed smoothly,
Since it is movable in the circumferential direction, the mounting position can be corrected on the product.
