摘要： PURPOSE:To facilitate the execution of the work of a large span slab, by setting an intermediate plate lower-side section fitted firmly on a deck plate with the salient strip apex section confronted with each crest surface, on a beam in parallel with each other, and by forming a hollow plate upper-side section with the arrangement of reinforcing bars on the deck plate and with the placing of concrete. CONSTITUTION:A deck plate 1 is laid by setting the reinforcing salient strip 2 of its flat crest type to be of a lower surface, and reinforcing bars 7 are arranged, and concrete is placed, and a hollow plate lower-side section 8 is molded. After the concrete is solidified, the deck plate 1 and the lower-side section 8 are reversed, and the deck plate 1 is mold-separated from the lower-side section 8. After that, the deck plate 1 is reversed again, and the respective crest surface of the reinforcing salient strip 2 is set confronted with the salient strip apex section of the lower side section 8, and anchor bolts 6 embedded previously in the lower side section 8 are used, and fastening integration is performed. Then, the lower side section 8 integrated with the deck plate 1 is set on a beam 20 in parallel with each other, and reinforcing bars 11 are arranged on the deck plate 1, and concrete is placed, and a hollow plate upper- side section 12 is formed. As a result, a timbering is not needed, and a large span slab can be easily formed.

摘要： PURPOSE:To facilitate execution by fixing a pair of upper and lower L-shape curved beam reinforcement connecting levers to each flange of mutually orthogonal beam steel frames and joining beam main reinforcements at the free end sections of the beam reinforcement connecting levers. CONSTITUTION:A gap between both connecting levers 1, 1 is filled and connecting section pieces 2 to beam steel frame flanges in the beam connecting sections of an externally projected column are fixed in the curved sections of a pair of the upper and lower L-shaped beam reinforcement connecting levers 1, 1, thus constituting a connecting fitting P. The mutually orthogonal both side edges of the pieces 2 are welded to the side edges of the side edges of orthogonal beam steel frames B respectively, and beam main reinforcements 4 are welded at the front ends of the connecting levers 1. The tensile force of the main reinforcements 4 is transmitted over the column made of SRC while column steel frames A are used in place of anchors through the fittings P and the flanges 3, to which the fittings P are welded, and transmitted as bending stress. Accordingly, since the main reinforcements 4 are joined to the free ends of the connecting levers 1, the orthogonal main reinforcements 4 are positioned in the same level, the structural bearing of beams is increased, and execution is enabled easily.

摘要： PURPOSE:To reduce the number of reinforcing bars and prevent cracks from being generated by embedding a prestressed precast concrete member previously into a section for generating the tensile stress of a reinforced concrete structural-body. CONSTITUTION:Between columns A, a beam form is assembled, and a prestressed precast member 2 is set on the lower end central-section of a beam, and a beam main-reinforcement 6 and an auxiliary reinforcement 7 are arranged, and beam concrete 8 is placed. Besides, the prestressed precast member 2 is formed in the shape of a reversed-trapezoidal cross-sectional area, and on the upper surface, a cotter 1 is set to be integrally bonded to the beam concrete 8. Besides, a reinforcing bar 5 projected from the side surface of the prestressed precast member 2 is set in the beam concrete 8, and the member 2 and a beam B are integrally formed. As a result, the prestressed precast member 2 is used in place of the tensile reinforcement of the beam B, and the cracks of concrete can be prevented from being generated.

摘要： PROBLEM TO BE SOLVED: To make a joint of column main reinforcement unnecessary in a joint construction between column and beam. SOLUTION: A concrete-filled joint portion 4 is interposed at the inner side of a steel plate formed to a ring between a column 2b provided as an upper column on a girder 1a and the girder 1a. Reinforcing bars as anchoring bars are distributed through the concrete joint portion 4 between the column 2b as an upper column and the column 2a as a lower column which are placed above and below the girder 1a thereby sandwiching the girder.

摘要： PURPOSE:To stabilize strength as well as reduce the amount of reinforcing bars in the joints by a method in which the projections of the beam base are integrally attached projectionally to the beams of a column and prestressed PC steel bars are buried in the joints between the column and the beam. CONSTITUTION:Projections 3 constituting the base of a beam are integrally formed projectionally in the beam-setting portion of a column 2 to form a PC column part 1 with beam. Prestressed PC steel bars 10 are buried in the joint between the part 1 and the column 2. Since the joint can be formed under stable quality control in factory without field construction, the strength can be stabilized, the amount of reinforcing bars used can be reduced, and the cross section of the parts can be reduced. The space of building can thus be effectively utilized.

摘要： PURPOSE:To make the cross section of a building frame small and to make economical bar arrangement possible by a method wherein a metal joint for reinforcing bars in different diameters made up by integrally joining a steel bar in large diameter and a steel bar in small diameter is used, and reinforcing bars in an RC column and an RC beam are joined therewith. CONSTITUTION:A metal joint A for reinforcing bars in different diameters is made of cast steel and is constructed by connecting a steel bar 1 in large diameter integrally with a steel bar 2 in small diameter. The steel bar 1 in large diameter is welded (W) to a reinforcing bar 3 in large diameter in an RC column B and an RC beam C, and the steel bar 2 in small diameter is welded to a reinforcing bar 4 in small diameter in the RC column B and the RC beam C. Thereby, reinforcing bars in different diameters can be used optionally in a continuous building frame, and the diameter in the middle part of the reinforcing bar can be made small while the number of reinforcements in the RC column and the RC beam is kept unchanged.
