Description

  The present invention relates to a corner corner handrail foundation structure, and in particular, when newly installing a handrail in an existing building, a corner corner handrail foundation for attaching a belt-like foundation plate supporting a handrail receiving metal to the wall surface of the corner corner. Concerning structure.

  For example, various buildings such as houses with handrails attached to wall surfaces have been developed so as to help elderly people and other residents walk indoors (see, for example, Patent Document 1). In addition, with recent aging, a handrail is frequently attached to an indoor wall surface at the time of renovation or renovation of an existing building (see, for example, Patent Document 2).

  When attaching a handrail to a wall surface, it is supported by a wall structural material such as a column or a stud arranged on the back side of the wall surface material constituting the wall surface, and a handrail receiving hardware is attached to the wall surface at a predetermined pitch. A method of installing a handrail via this handrail receiver is generally known, and by supporting the handrail receiver on a wall structural material such as a pillar or a stud, the handrail is firmly and along the wall surface. It becomes possible to install in a stable state.

  In addition, when attaching handrail brackets supported by the wall structural material on the back side of the wall surface material such as pillars and studs, for example, when building a new building, consider the position and pitch where the handrail brackets are mounted. Since the structural material can be designed and arranged in advance, the handrail receiver can be easily attached.
