Description

[Detailed Description of the Invention] (Industrial field of application) This invention comprises a decorative material-coated rectangular steel tube used as a pillar or a beam when the decorative material-coated rectangular steel tube is formed by coating the surface of the rectangular steel tube with a decorative material. The present invention relates to a joint structure of columns and beams.

(Prior Art) In general, wood, steel aggregate, etc. are used for structural materials such as columns and beams of buildings.

Also, the columns and beams made of wood are joined by mortise processing or battledore bolts, and the columns and beams made of steel aggregate such as H-section steel and square steel pipe are joined by welding and bolting. It is being appreciated.

(Problems to be solved by the invention) However, although the columns and beams made of wood are excellent in design due to the natural wood grain pattern, there are weaknesses in strength, and in particular,
There is a problem in that the joint portion is unavoidably reduced in strength due to cross-section loss due to mortise processing or the like.

On the other hand, columns and beams made of steel aggregate such as H-section steel and square steel pipe are excellent in strength, but joint fittings such as joint bolts are often exposed to the outside, which is inferior in design. There was a point.

This invention has been proposed in order to solve the above-mentioned conventional problems, and is a decorative material obtained by coating the surface of a rectangular steel pipe with a decorative material such as wood, synthetic resin, polymer cement mortar, resin mortar. An object of the present invention is to provide a joint structure between a column and a beam made of a decorative material coated rectangular steel pipe, the joint of which does not impair the design in appearance when the coated rectangular steel pipe is used as a column and a beam. .
