Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail unit, and more particularly, to a handrail made of an aluminum alloy because, for example, the strength of a steel handrail is reduced due to corrosion or the like due to long-term use. The present invention relates to a handrail unit which is particularly effective when it is exchanged with a handrail unit.

[0002]

2. Description of the Related Art For example, iron railings are often provided in corridors and rooftops of schools, hospitals, apartments, and the like, but such railings are exposed to rain and snow.
Long-term use may cause rust and corrosion, resulting in reduced strength and safety problems. In such a case, the iron handrail is often removed and replaced with a handrail made of an aluminum alloy having excellent resistance to rain and snow.

[0003]

[Problems to be Solved by the Invention] Generally, buildings where handrails are replaced often have passed 20 to 30 years after construction, and the concrete strength of the skeleton has been reduced.
In the same manner as in the related art, a supporting method in which the support of the handrail is erected on the floor and the entire handrail is supported on the floor cannot secure the required strength as the handrail.

The present invention has been made to solve the above-mentioned problem, and has as its object to obtain a handrail unit capable of securing a predetermined strength even when installed in an old building.

[0005]

In a handrail unit according to the present invention, at least two upper and lower portions of a cubic standing upright along respective opposing side walls of a wall having an opening are fixed to the wall, respectively. In a handrail having a lower chord and a cap fixed to a cubic stand and a plurality of vertical rails attached between the lower chord and the cap, the ends of a long piece having at least two loose holes are the same. A fixing member having a screw hole provided by bending the end thereof in the opposite direction after bending in a direction, a web having a screw insertion hole and a flange having a loose hole, and a web. And a U-shaped support fitting having a screw hole in the flange, wherein the flange of the fixing bracket is fixed above and below an inner wall of a substantially U-shaped cubic cross section, and the support bracket is opposed to the cubic. Side wall Each fixed, the long piece is fixed to the fixing member having the wall fixed to the wall, the web of the fixing bracket is fixed to the fixing piece of the fixing member, and both ends of the lower chord material are fixed to the supporting bracket by fitting. It was made.

[0006]

A long piece of a fixing member is fixed to both side walls of a wall having an opening at at least two places, and a cubic is inserted into the fixing member, and a fixing bracket is fixed to the fixing piece to erected the cubic. I do.
Then, both ends of the lower chord material are fixed to the support fittings provided at the lower portions of the both stands, respectively, and a sash is fixed to the upper part of the cubicle, and a plurality of vertical members are attached between the lower chord member and the cubicle. As a result, the horizontal load applied to the coping is supported by the four fixed portions of the cubic and the wall.

Fixed by 0. Finally, if the caulking material 24 is filled between the partitions 3, 3a and the wall, the construction of the handrail unit is completed.

As described above, the handrail 10 is attached to the building frame, and the horizontal load applied to the coping 5 is firmly supported by the four fixed portions of the cubicles 3 and 3a and the walls 2 and 2a. The above-described assembling order is an example, and can be changed as appropriate according to the situation at the site.

[0019]

As described in detail above, in the handrail unit according to the present invention, at least two cubicles are fixed to the wall along the opposing side walls of the wall having the opening, respectively. Since the lower chord material and the cap are fixed to each other, a vertical rail is attached between them to form a handrail, and the horizontal load applied to the cap is supported by the four fixed parts of the cubic and the wall, A handrail with excellent three-dimensional strength and good appearance can be obtained. In addition, since the cubic is fixed to the wall by the fixing member and the lower chord is fixed to the cubic by the support bracket, the construction is easy and the cubic can be firmly fixed to the wall.
