DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail mainly erected on a veranda of a building or an outer edge of a corridor.

[0002]

2. Description of the Related Art In a conventional handrail, a handrail unit in which a handrail unit is assembled in advance in a factory or the like, only a support is erected at the site, and the handrail unit is mounted on the support is known.

[0003] This type of handrail is easy to construct on site, and since a handrail unit is used, it can be easily replaced at the time of renovation. It has the advantage that the production can be omitted and the cost can be reduced as compared with ordinary metal handrails or concrete handrails.

[0004]

In the conventional unit handrail, a handrail unit is retrofitted to a column, and usually, bolts are fastened at the base and upper portion of the column, and further, a joint (connecting tool) is attached to the column. ) Is attached via the Kasagi.

As described above, in the conventional unit handrail, the handrail unit is fixed at the upper and lower portions of the column, and the fixing is performed by using the connecting tool, so that it is unexpectedly troublesome. . Furthermore, since the cap is located on the indoor side of the support, it is naturally located on the indoor side of the handrail unit. As a result, the cap on the indoor side tends to slightly generate a feeling of oppression.

In addition, since the unit handrail is subjected to a load such as a human body, it is necessary to improve the strength.

Therefore, the present invention provides a unit handrail using a handrail unit, on the one hand, it is possible to save labor in the construction more than the conventional unit handrail, and on the other hand,
A handrail unit that can be mounted more firmly than before and has high safety is proposed.

[0008]

As described above, since the handrail unit is attached to the concave groove provided on the lower surface of the skirting and fixed to the skirting,
Only one fixing point is required, simplifying construction. Also,
Since the column is also attached to the groove via a joint, both the column and the handrail unit are attached, the number of members is reduced, and the cost can be reduced and the construction can be simplified.

According to a second aspect of the present invention, in the first aspect of the present invention, the handrail unit has a horizontal cross section having a U-shaped cross section at a lower portion thereof, and the bracket includes the handrail unit. And a handrail having a handrail unit attached to the support via the mounting bracket and the bracket.

As described above, since the column is attached to the lower horizontal ridge of the handrail unit through the mounting bracket and the bracket, the mounting strength of the column and the handrail unit is improved, and the load on the human body or the like is increased. Is safe even if loaded.

According to a third aspect of the present invention, in the first or second aspect of the present invention, a reinforcing member is provided inside the heddle, and the reinforcing member is integrally formed by the concave groove. Is a handrail provided in the inside.

As described above, the reinforcing member is provided inside the cap,
In addition, since this reinforcing member is provided in the concave groove in which the column and the handrail unit are provided, it does not require a mounting member or the like as a separate member, improves the strength of the handrail without complicating the mounting operation. It is possible.
