摘要： PROBLEM TO BE SOLVED: To provide a column base that can be constructed with reduced cost for its necessary members and for which quality can be ensured with respect to management in execution of work by a method wherein functions of the column base are concentrated more to column base metals as compared with a conventional column base in the same capacity where a base plate is used. SOLUTION: A column base for steel column is constructed of joining metals 8 each composed of side plates 11 sticking fast to external faces of a steel column 1 and a base 12 extending outward from the side plates 11. Then the joining metals 8 in plural numbers are fixed to the outside at the lower end of the steel column 1, and the steel column 1 with the joining metals 8 fixed thereto is installed the surface of a concrete foundation 6 with a bottom plate 9 interposed in between. A hole provided at each of the bases 12 of the joining metals 8 is put over each of anchor bolts 3 planted in the concrete foundation 6, and a nut 4 is screwed down onto a screw formed at the tip of each of the anchor bolts 3 from the upside of the base 12.

摘要： PURPOSE:To simplify work execution by using a U-shaped anchor bolt instead of a straight anchor bolt, and fixing it by a filling type anchor plate by using a screw reinfofcement as the U-shaped anchor bolt. CONSTITUTION:A U-shaped anchor bolt 1 and a reinforcing reinforcement 2 are embedded in a footing, and a base plate 11 is pressed down by a nut 3 and a flat washer 4, and a steel frame column is fixed. When a filling type screw anchor plate is used as the U-shaped anchor bolt 1, a loose hole 15 is arranged in the base plate 11 of a steel frame column base, and the base plate 11 is fixed by a filling type anchor plate 13, and a fixative is injected from an injection hole 14. Thereby, a footing rising part is shortened, and a design of the foot rising part is facilitated, and work execution of an anchoring part can be simplified.

摘要： PURPOSE:To provide a column-beam jointing metal fixture high in strength and reliability and manufactured at low cost. CONSTITUTION:In a column-beam jointing metal fixture comprising a bottom plate part 12a and a protruding part 12b formed into integral T-shape so as to joint a column of steel structure and a beam with I-shape cross section through a bolt and a nut, the bottom plate part 12a made of iron and steel material is formed by a casting, forging, rolling or extruding means in such a way that the thickness measure is gradually reduced from the base part outward in the axial direction of the column. The base part is integrally provided with a protrusion gradually reduced in its thickness measure toward the longitudinal direction of the beam and provided at its tip part with a parallel part of the length measure not less than its thickness measure, and the protruding part 12b formed into quadrangular shape out of a steel plate of the thickness measure not less than the flange thickness of the beam is jointed to the protrusion by welding. Bolt holes are then bored in the specified positions of the bottom plate part 12a and protruding part 12b.

摘要： PURPOSE: To enhance an energy absorbing capacity by fixing a base plate joined with the lower end of a steel column on foundation concrete with U-shaped anchor bolts and nuts buried in the foundation concrete. CONSTITUTION: The lower end of a steel column 5, such as an H-shaped post or a square-shaped column is fixed with a base plate 2 and buried in foundation concrete 6 by screwing lower nuts 3 into the upper ends of an U-shaped anchor bolt 1. A mount-shaped central mortar area 12 is formed on the top of the foundation concrete 6. The base plate 7 is loaded on this central mortar area 12 so that upper nuts 2 may be fastened from the top of the base plate 7. Then, the clearance between the bottom of the base plate 7 and the top of the concrete 6 is filled up with non-shrinkage mortar 13, thereby fixing the steel column 5. It is, therefore, possible to enhance an energy absorbing capacity of a column base.

摘要： PURPOSE:To enhance strength by installing a projected part which is adapted to the cross section shape of a steal post to a base plate having anchor holes and forming a sloping part designed to relax local stress concentration on this projected part. CONSTITUTION:A cast steel or forged column base hardware 1 in one piece structure having a projected part 5, which is adapted for a plane substantially cross-shaped cross section of a steel post, is formed on a base plate 4 having anchor bolt holes 3. The projected part 5 has a flange 7 and a web 8 while it is also provided with a sloping part 6 on the base plate 4 which is designed to relax stress concentration. Furthermore, the span between the outer surface of the base plate 4 and the outer surface of the projected part 5 is set within 100mm. The outside shape dimensions around the base plate of the column base hardware 1 is limited to be a minimum. I is, therefore, possible to make the most use of an application space for a building.

摘要： PROBLEM TO BE SOLVED: To prevent the generation of cleavage to mortar and attain miniaturization by providing a reinforcing frame formed of steel material, at the peripheral edge part of mortar at the time of anchoring a steel column base with a column base hardware jointed to the lower end part of a steel column, onto foundation concrete through an anchor bolt, interposing mortar at the upper end face of the foundation concrete. SOLUTION: A steel column base 6 with a column base hardware 4 jointed to the lower end part of a steel column 5 is anchored onto foundation concrete 9 through an anchor bolt 1 embedded in the foundation concrete and a nut 9 screwed with the upper end part of the anchor bolt 1, interposing mortar at the upper end face of the foundation concrete 2. In this case, a reinforcing frame 11 formed of steel material is provided at the peripheral edge part of mortar 7. The reinforcing frame 11 is formed of a band steel plate of 6-9mm in thickness, for instance, jointed in endless shape, and installed on the foundation concrete 2 before the installation of the steel column base 6 so as to serve as a form at the time of filling mortar 7. A space W can thereby be made small, and column base structure can be miniaturized.
