Description

The present invention relates to a fixing structure for fixing a material to be fixed to a steel structural column having a vertical groove long in the vertical direction.

Conventionally, when a plate material is fixed to a pillar material of a temporary building, a side edge portion of the plate material is inserted into a vertical groove provided in the pillar material to fix the plate material (for example, Patent Document 1). reference). The pillar material in the present invention is fixed by welding a C-shaped steel material to two orthogonal surfaces of a steel material having a quadrangular cross section so that the vertical grooves face outward, and the plate material is fixed to the vertical grooves to form an outer wall. It is said that the plate material can be easily fixed to the pillar material with good appearance.

By the way, in general, structural columns of buildings such as houses are required to have a high degree of design, so they are rarely used in the case of steel structures, and steel structural columns are hidden by covering them with a wall or decorative material. Often done. Further, even when the structural columns are exposed, the metal fittings are largely exposed, which is not excellent in design.

Further, for example, it is known to provide colonnades and horizontal grids with wooden bases instead of structural columns for line-of-sight control between rooms, but a technique using steel structural columns for line-of-sight control is not known.
