    • PROBLEM TO BE SOLVED: To erect an iron skeleton column at low cost and with high positional precision by fixing a column leg hardware made of steel in which a pedestal in which a bolt hole is drilled is extended and provided on a foundation in a corner part of a hollow and square frame body and welding a lower end of the iron skeleton column on an upper end part thereof. SOLUTION: A column leg hardware 15 made of steel is manufactured by extending a pedestal 11 in which a bottom face 10b and a lower face 11b are aligned on the same face outward from a corner part 10a of a hollow and square frame body 10. A bolt hole 12 is drilled in each pedestal 11, and a center line 13 is indicated at the center of each side of the frame body 10. First, the column leg hardware 15 is fixed on a foundation by inserting an anchor bolt embedded in the concrete foundation into the bolt hole 12 of the pedestal seat 11 and tightening it by using a nut. Next, a lower end of the iron skeleton column is abutted and erected in an upper part of the frame body 10 and is welded. Since an opening tip for welding is provided in an upper end of the frame body 10, a lower end of the iron skeleton column can be welded while it is cut on plan, and positional precision can be ensured. Since the column leg hardware 15 can be standardized easily, it is possible to manufacture the column leg hardware 15 having high quality at low cost in a factory.

    • PURPOSE:To shorten the length of a side plate part for reducing the manufacturing cost of a connecting fitting by forming recessed parts in the side plate part of a column and beam connecting fitting consisting of a base plate part to be connected to a steel structural column and a side plate part projected on the base plate part, and by boring bolt holes in the recessed parts for connecting the fitting to a steel structural beam. CONSTITUTION:Recessed parts 3b are formed on one side surface of the side plate part 3 of a column and beam connecting fitting 1 consisting of a base plate part 2 to be connected to a steel structural column 4 and a side plate part 3 projected on the base plate part 2, and bolt holes 3a are bored in the recessed parts 3b. The outer surface at the end of a steel structural beam 5 is arranged so as to be opposite to the side surface on which the recessed parts 3b of the side plate part 3 of the connecting fitting 1 have been formed, and the steel structural beam 5 and the side plate part 3 of the connecting fitting 1 are connected by means of high-strength bolts 6. The circumference of the bolt hole 5a of the steel structural beam 5 is deformed by tighted of the bolt, and is fitted in the recessed part 3b of the side plate part 3. Thereby, a necessary frictional force between the steel structural beam 5 and the connecting fitting 1 can be secured by a small number of bolts.
