摘要： PROBLEM TO BE SOLVED: To construct a rigid-frame structure which enables one piece of steel beam to be directly joined to a through steel column at a junction structure between a closed-cross-section column and a beam without requiring the steel column to be cut and a diaphragm and a bracket beam to be welded in place as they should in conventional cases, and which can stabilize the quality of the junction structure, reduce its cost, and sufficiently satisfy dynamic functions by means of the relatively simple column-to-beam junction structure. SOLUTION: A corner hardware 3 having a bolt hole 3a tilted relative to the direction of the axis of a steel beam 2 within a horizontal plane is mounted on the outer surface of a corner, of the junction of a steel column 1. A sleeve hardware 4 is mounted on the flanged end of the steel beam 2 in such a manner that the central axis of a bolt member hole 4a in the sleeve hardware 4 can continue with the central axis of a bolt-member hole 3a in the corner metal fitting and that its mating end face can abut to the mating end face of the corner hardware 3 A bolt 6 or a deformed steel bar is passed into the corner hardware 3 and the sleeve hardware hardware 4, and a nut 8 is attached to the end of bolt and fastened to tighten and integrate the corner hardware 3 and the sleeve hardware 4 together.

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： 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.

摘要： PROBLEM TO BE SOLVED: To connect a steel-framed column and a steel-framed beam easily and rigidly without using a diaphragm as in conventional devices in the connecting-section structure of the steel-framed column comprising a square- shaped steel pipe, etc., and the steel-framed beam composed of H-steel, etc. SOLUTION: Joint metals 3 (3-1, 3-2) having boltholes 3a on the insides are fixed in parallel with the longitudinal direction of the steel-framed beam 2 on both side sections of upper-lower flanges 2a so that out-of-plane bending applied to column side plates is reduced at the connecting end sections of the steel-framed beam 2. Bolt through-holes 1b are bored to the side plates 1a in the connecting sections of the steel-framed column 1 in response to the places of the joint metals 3, the connecting end sections of bolts 4, etc., inserted into the through-holes and penetrated into the column are put into the boltholes 3a of the joint metals 3, and nuts 5 are installed and clamped to bolt front-end sections projected from the joint metals 3 or one-side bolts are mounted and tightened to the joint metals 3 and the side plates 1a from the steel-framed beam side, thus firmly joining the joint metals 3 and the steel-framed beams 2 to the steel-framed column 1.

摘要： PURPOSE:To prevent the buckling deformation of a steel pipe column and improve the strength of a junction section structure between the steel pipe column and a steel- framed beam by diagonally protruding brackets on corner sections of the beam junction section of a steel pipe column, and connecting the steel-framed beam to the brackets via junction metals to connect the steel pipe column and the steel-framed beam. CONSTITUTION:Brackets 4 are diagonally protruded on corner sections of the beam junction section of a steel pipe column 1. Both the right and left end sections of the fixed section 3b of junction metals 3 are fitted to the brackets 4 with high-strength bolts 7. Upper and lower flanges 2a of a steel-framed beam 2 are connected to connection sections 3a of the junction metals 3 with high-strength bolts 7. The end section of the web of the steel-framed beam 2 is connected to a junction plate 8 protruded at the side section of the steel pipe column 1 with high-strength bolts 9. The axial force by the bending stress of the upper and lower flanges 2a of the steel-framed beam 2 is applied to the webs of the steel pipe column 11 parallel with the steel-framed beam 2 via the brackets 4 as the axial force, and it is transferred to the upper and lower flanges 2a of the steel-framed beam 2 on the opposite side.

摘要： PROBLEM TO BE SOLVED: To transmit a shearing force to a bolt so as to improve a load with standing property and so as to surely prevent slack by filling a solidifying filling around a recess, which is formed in a nut mounting part on the upper face of a base plate, and a bolt hole. SOLUTION: In connection of a base plate 2 of a column leg to an anchor bolt 1, nuts 3, 4 are fastened after the base plate 2 is clamped between them, and an adhesive 5 developing strength is filled around a recess 7, which is previously arranged in a nut mounting part on the upper face of the base plate 2 and is provided with a dimension larger than the nut outside diameter, the nut 4, the anchor bolt 1, and a bolt hole so as to be solidified. In the bolt hole on the back face of the base plate 2, an area larger than the outside diameter dimension of the nut 3 at least is formed into an even plane 8. A recess 6 is arranged in the nut 4 part on the base plate 2 upper face, and a bevel 9 is formed around the bolt hole in the recess 7, so that the adhesive 5 can be easily filled. In this way, the adhesive 5 is filled and solidified around the bolt screw part and the base bolt hole, and as a result, a shearing force can be transmitted to the bolt.
