The present invention relates to a method of standing a handrail support column and a structure of standing a handrail support column.

[0002]

2. Description of the Related Art Conventionally, various construction methods have been used for establishing a handrail support for supporting a handrail of a building. Since this type of handrail support column is required to have a high degree of safety, sufficient reliability is required for the establishment of the tree, and the cross-sectional area of the handrail support column is relatively large.

[0003]

For this reason, for example, if a thick pillar itself is to be buried in the parapet surface, a large hole for building must be drilled in the concrete, which increases the construction time on site. In addition to the above, there is a problem that the construction work itself becomes difficult.Therefore, in general, when pouring concrete to form a parapet, it is necessary to form a hole for building a pillar in a standing position in advance. Therefore, it was difficult to retrofit the handrail.

The present invention has been made in view of the above problems, and proposes a method of standing a handrail support column which is simple in construction, easy in post-installation, and highly reliable in strength after construction. It is an object of the present invention to provide a structure of a handrail support used for the upright construction.

[0005]

According to the present invention, there is provided a method for erecting a handrail support column, which comprises a columnar main body of an aluminum handrail which will be a handrail support when a handrail support column made of an aluminum drawbar is established on a concrete parapet surface. On the axis of
A screw shaft made of steel such as stainless steel is screwed, one end of the screw shaft is made to project from the lower end of the columnar main body, and an inner diameter and a screw shaft slightly larger than the thread diameter of the screw shaft are provided at the pillar establishing position of the parapet. After forming a support column establishment hole having a dimension slightly deeper than the protruding length of the column with a drill and filling the support establishment hole with an adhesive made of an epoxy resin, the support establishment hole was projected from the lower end of the columnar main body. The gist is to insert the protrusion of the screw shaft and establish the columnar main body on the parapet surface by hardening the adhesive.

The structure of the handrail post used for the above-mentioned construction is as follows. In the handrail post made of an aluminum barb erected on the concrete parapet surface, the columnar main body of the aluminum barb to be the handrail column is The gist is that a screw shaft made of steel such as stainless steel is screwed, and one end of the screw shaft is projected from the lower end of the columnar body. At the same time, it is possible to provide a hakama-shaped cover member that is integrated with the columnar main body by screws or adhesion.

[0007]

According to the above method of erected the handrail support, the screw shaft projecting from the lower end of the columnar body can be inserted into the surface of the concrete on which the handrail support is to be established (slightly larger than the mountain diameter of the screw shaft). It is only necessary to drill a pillar establishing hole of a size slightly deeper than the inner diameter and the protruding length of the screw shaft with a drill, and then the handrail supporting pillar can be firmly established at the target position with an adhesive made of epoxy resin. It comes out.

Further, in the handrail support column having the above-mentioned structure, a screw shaft made of steel such as stainless steel is screwed into the shaft center of the columnar body made of aluminum, so that the screw shaft constitutes the core structure of the support column. In comparison with the aluminum columnar structure, the rigidity against a lateral load is increased and the structure becomes robust.
