Construction and civil engineering steel structure assembly

摘要

The present invention relates to an iron structure assembly for construction and civil engineering, and aims to solve the problem of difficulty in structurally working an H-shaped beam in vertical and arbitrary angle assembling. To this end, the present invention is characterized in that the horizontal ribs 3, 3 ', 3a (3a, 3b) are folded by bending portions 5, 5', 5a, 5a ' , 3a ') are connected to each other. The S-shaped beam 1 is assembled by an S-shaped connecting beam 11 which is superimposed by riveting on the side from the side to be connected with the S-shaped beam 1 'which is butted together. Further, the S-shaped beam and the S-shaped connecting beam are vertically assembled since they are riveted with another S-shaped beam 1 which is coupled to the web and overlapped with the upright vertical connecting member 15. Thus, the S-beam is easily and rigidly assembled by standardized parts.
