摘要： PURPOSE:To make it possible to insert a steel plate into a concrete force inlet and smoothen a finished surface by connecting to an intermediate part by way of a steel plate extrusion pipe and extruding concrete remaining in the pipe and the steel plate to the side of a steel pipe. CONSTITUTION:After concrete is injected with force, a concrete force-in pipe 3 is closed and an insertion hardware 6 to be housed in a steel plate extrusion pipe 2 is extruded with an arm of a jack 4. Then, the movement of the insertion hardware 6 is halted at the position at which a backing is located when it is welded and a small amount of concrete remaining in the extrusion pipe 2 is extruded into a steel pipe 1. After the insertion hardware 6 is inserted into a concrete force-in port, a presser hardware 5 is extruded thereinto, thereby fixing an insertion steel plate 6A. Then, the concrete is cured, the steel plate extrusion steel pipe 2 is removed from the steel pipe 1 while a guide steel plate 6B and an elastic body 6C and a reinforcing board are removed from the insertion hardware 6, but only the extrusion steel plate 6A is arranged to remain. The peripheral surface of the insertion steel plate is welded with the end face of the concrete force-in port, thereby completing this work.

摘要： PURPOSE:To shorten construction period by using welding structure for a one directional vertical reinforcing member out of cross-shaped directions of joints and forming the other directions as a back-up of a long fastening bolt. CONSTITUTION:A plurality of vertical boards are faced with each other crosswise in such a fashion that they may be inscribed inside square steel pipe posts 1 and 2, thereby forming reinforcing members 3. The both sides of the reinforcing members 3 are welded to a part to which flanges of an H steel beam 7 of two strip-shaped members 1 are to be welded. Splits T4 are laminated on the strip-shaped members 2, which are welded in such a fashion that they may close the two strip-shaped members 1 from the outside of the square steel pipe posts 1 and 2 and clamped and fastened with long fastening bolts 5 and nuts 6. It is, therefore, possible to fasten the square steel pipe posts without producing any uneven deformations.

摘要： PURPOSE:To enhance the assembling workability of the connection part of a steel frame column in the inside of which concrete is filled and steel frame beams. CONSTITUTION:A steel frame column 2 of a closed sectional shape in the inside of which concrete 1 is filled, and steel frame beams 3 are joined by using a connection member 4 consisting of flange plates 41 to be joined by bolts to the flanges 31 of the respective steel frame beams 3 and anchor bars 43 which are extended from the flange plates 41 into the inside of the steel frame column 2 and are anchored by the concrete 1. The tensile force and compressive force from the steel frame beams 3 are transmitted to the concrete 1 by the anchor bars 43. Thereby, the working manhours and welding quanitity to the steel frame column 2 can be reduced, and the assembling workability of the connection parts can be enhanced.

摘要： PURPOSE:To enhance the assembling and construction workability of the connection parts of a steel structure column of a closed sectional shape and steel structure beams. CONSTITUTION:A steel structure column 1 of a closed sectional shape and steel structure beams 2 are joined by using through plates 3, 3 which are penetrated between the opposite flanges 11, 11 of the steel structure column 1 so as to form vertical surfaces and which are arranged in parallel to each other in the width direction of the steel structure beams 2, and flange plates 4 which are overlapped on the flanges 21 of the beam 2 and joined thereto by bolts. By previously welding the flange plates 4 to the through plates 3 so that the transmission of stresses between the opposite steel structure beams 2, 2 can be carried out by the through plates 3, the working manhours and welding quantity to the steel structure column 1 can be reduced, and the assembling and construction workability of the connection parts can be enhanced.

摘要： PURPOSE:To enhance the extent of bearing force in a joint consisting of a reinforced concrete pole and a steel frame beam and simultaneously improve the assembling operability and workability. CONSTITUTION:A section in a joint of a reinforced concrete construction pole 1 is formed by a steel pipe concrete construction from a steel pipe 21 and concrete 22 being filled up in the inner part and main reinforcing steel 11 being arranged in succession to a general part pole 1, and each bolt 5 piercing through each split Y fitting 5 connected to respective ends of steel frame beams 3 is screwed in each reinforced fitting 4 inscribing the steel pipe 21, thereby connecting the steel frame beams 3 to the pole 1. Since the section of the joint of the pole 1 is of steel pipe concrete construction, bearing force in the joint is high enough as well as since the steel frame beams 3 are connected to the pole 1 through these bolts, assembling operability is heightened. In addition, as the reinforced fittings 4 for joining the steel frame beams 3 are inscribed with the steel pipe 21, an inner structure of this steel pipe 21 is simplified, so that workability is heightened too.

摘要： PROBLEM TO BE SOLVED: To provide a damper and a structure for vibration control, easy to install in a building and excellent in base isolation performance, eliminating damage to the beauty and convenience of the building. SOLUTION: The vibration control damper 3 is installed within the framework of the building, which is composed of right and left columns 1 and 1 placed at a prescribed interval and a beam 2 laid across the columns 1 and 1. The damper 3 is composed of a lower chord member 3a laid across the columns 1 and 1 and a plurality of vertical members 3b installed between the chord member 3a and the beam 2. Both the chord member 3a and the vertical members 3b are formed with a plastic deformation part 3c undergoing plasticization by stress at a fixed value or above. In the deformation part 3c, the chord member 3a and the vertical members 3b are partially formed in such a constricted manner as to have a small diameter.
