摘要： PROBLEM TO BE SOLVED: To prevent panting shear breakdown generated on the periphery of a pillar in a flat slab, and easily perform shear reinforcement of the shell wall, the foundation slab, or the like of a nuclear reactor building by the use of bar-like shear reinforcement. SOLUTION: For beam part main reinforcements 6a, 7a on the periphery of a pillar in a flat slab, beam type reinforcements 8, 9 formed so as to surround the beam part main reinforcements are provided, the flat slab on the periphery of the pillar is shear reinforced, concrete is confined, and panting shear breakdown is prevented. Otherwise, a plurality of bar-like reinforcements in which facing hardwares are threadedly fitted and fixed to both end parts of threaded bars are standingly arranged in the direction of the slab thickness, or the beam type reinforcement and bar-like reinforcement are jointly used. Further, the bar-like reinforcements are arranged in the shell wall, the foundation slab, or the like of a nuclear reactor building, and by strongly fixing a fixing hardware with the threaded bars by mortar or the like, workability is improved.

摘要： PURPOSE:To enhance a capacity to fill up concrete by increasing the plate thickness of a diaphragm in a steel pipe concrete post and boring a larger hole to fill up concrete. CONSTITUTION:In a joint part between a steel pipe concrete post 1 and a beam 2, the plate thickness of diagram 3 is increased, thereby forming a larger concrete-filling opening 4 with a high strength material. The shape of the filling opening is designed to be square or octagonal, which makes it possible to transmit force more reasonably and hence improve its capacity to fill up concrete. It is, therefore, possible to secure an enough strength and facilitate construction work.

摘要： PURPOSE:To decrease the interference with finishing materials, to miniaturize them to reduce welding work and to shorten a construction period by welding a ribbed diaphragm to a steel pipe column, and welding an H-shaped steel frame beam to the diaphragm to join the column and beam. CONSTITUTION:A ribbed diaphragm 3 is welded to a steel pipe column, and a flange of an H-shaped steel frame beam 2 is welded to the other end of the ribbed diaphragm 3. At that time, in cases where the steel pipe column 1 is used for a steel pipe concrete column, the steel pipe column is filled with concrete 4, and in cases where the concrete 4 is hard to bond the steel pipe column 1, studs 5 are provided. In cases where part of the flange of the H-shaped steel frame beam 2 is transferred to the ribbed diaphragm, part of a trapezoid and longitudinal rib is welded to a flat plate-like section having the same width as that of the flange of the beam 2 to form the ribbed diaphragm, and the diaphragm is welded to the steel pipe column 1. After that, the flange of the beam 2 is appropriated to one end to be partially eliminated, a web of the beam 2 and the diaphragm are welded to weld the flange of the beam 2 to the diaphragm, and a joint is constituted.

CONSTITUTION:A skeleton 4 having each piece 4a radially protruded from the center which has each X-shaped form from four directions as the whole is formed, and a connecting piece 5 is mounted on the top end of each piece 4a of the skeleton 4 in the orthogonal direction to constitute an inner diaphragm 3. The inner diaphragm 3 is arranged in a steel pipe column 1 in such a manner that the connecting piece 5 makes contact with the inner circumferential surface of the steel pipe column 1. A steel beam 2 has a split tie 7 on the end. The split tie 7 making contact with the outer circumferential surface of the steel pipe column 1 and the connecting piece 5 are fastened by a bolt with the steel pipe column 1 between.

摘要： PURPOSE:To secure the rigidity of a joint by welding an inner reinforcing plate to the inside of a steel pipe column and the flange of a beam to be joined to the above part. CONSTITUTION:An inside reinforcing plate 3 severally having four reinforcing members at four corners is welded to a square steel pipe column 1 so as to inscribe to it, and is provided with a window hole having an enough size for filling up concrete. The inside reinforcing plate 3 is cut out of one sheet of plate maternal and used, and the flange of a beam 2 is welded to each part of the steel pipe column. Thus the cutting of the column becomes unnecessary, and a structure being less in a welding quantity can be formed.

摘要： PURPOSE:To simplify a method of construction, by a method wherein sleeve-shaped members each are placed at positions in a steel pipe reinforced concrete column and at these positions corresponding thereto the flanges of beams are to be weld joined with the steel pipe reinforced concrete column, following which the sleeve-shaped members each are weld joined with skin plates and at these positions corresponding thereto the flanges of the beams are weld joined with the steel pipe reinforced concrete column. CONSTITUTION:The four corners formed of four skin plates 3' are weld joined with each other and a columnar shape, that is a steel square pipe reinforced concrete column 3 is formed. After that, respective sleeve-shaped members 1 are placed at positions in the steel square pipe reinforced concrete column 3 and at these positions corresponding thereto the flanges of the beams 2 are to be weld joined with the steel square pipe reinforced concrete column 3, following which the sleeve-shaped members 1 each are weld joined with the four skin plates 3' forming the steel square pipe reinforced concrete column 3. After that, at these positions corresponding to the positions where the sleeve-shaped members 1 in the steel square pipe reinforced concrete column 3 are welded, the flanges of the beams 2 are weld joined with the steel square pipe reinforced concrete column 3. In this way, the sleeve- shaped members 1 each are weld joined directly with the skin plates 3', and a method of construction also can be simplified thereby.

摘要： PROBLEM TO BE SOLVED: To enhance the workability by arranging longitudinal reinforcing bars between the top end bars and the bottom end bars, by mutually intersecting a set of bent-formed transverse reinforcing bars by straddling a column and the flat slab and by arranging to an X-letter shape on a transversal section inside the slab. SOLUTION: Among top end bars 6 and bottom end bars 7 perpendicular in two directions planwise, longitudinal reinforcing bars 4 are arranged by linking them to the top end bars 6 and bottom end bars 7 with intervals held in the length direction between the top end bars 6 and the bottom end bars 7 at least in one direction. Then, the horizontal portion 51 of two or more transverse reinforcing bars per set 5 are, anchored inside a column 1, its sloped portions 52 are intersected to an X-letter shape and arranged by straddling the column 1 and the flat slab 3. In addition, anchoring members 8 are connected to the end portion of a horizontal portion 51 of the transverse reinforcing bars 5, which comprise flanges spreading from a shaft portion and part of the shaft portion to the outer periphery and transmit a tensile force to be borne by the transverse reinforcing bar 5 to the concrete of the slab 3 or the column 1 thereby securing an anchoring strength into the concrete. By doing this, the workability for bar arrangement can be improved.
