Description

[Detailed description of the invention] This invention relates to the structure of the attachment part of the baluster to the wing wall.

Stairs that connect two floors with different heights are generally constructed by supporting treads or soffit boards with side walls, wing walls, or girders. If the height is low, it is necessary to install handrails for pedestrian safety and aesthetic considerations. This handrail is usually provided by fixing the lower ends of a plurality of handrails attached to a handrail main body to a wing wall or girder with fixing fittings such as nails or bolt nuts.

However, in the handrails with the above structure, the heads of the fixing metal fittings that fix the balusters are exposed on the outer surface of the lower end of the balusters, which mars the aesthetics of the entire staircase. For this reason, measures have been taken to either attach the fixing metal fittings to an inconspicuous position or to conceal the heads of the fittings, but neither of these methods completely conceals the heads of the fittings, and they have the disadvantage of making the assembly work of the stairs more cumbersome.

This idea was developed based on the above-mentioned background, and provides a structure for the attachment part of the balustrade to the side wall that can be assembled easily and quickly, and also completely hides the fixing fittings that fix the balustrade. The purpose is to
