摘要： PURPOSE:To reduce quantities of steel framed members and to make it possible to lower the height of a truss by springing a long span trussed girder out of a bearing point of each column head, and providing downward force for steel materials mounted to the spring end to introduce prestress. CONSTITUTION:A long span trussed girder 1 is borne by each column head pin of columns 2 and 2' opposed to each other and a roller and, at the same time, the end of the girder 1 is sprung downward of the bearing point of the column head. After that, steel materials 4 and 4 are mounted to the spring end, and the steel materials 4 and 4 are joined to earth anchors 3 and 3 to be provided in advance. Then, the downward forces T and T are provided to the steel materials 4 and 4, and prestress is introduced to the trussed girder 1. According to the constitution, stress and deformation caused by dead weight of the trussed girder 1 and weight of finishing materials can be reduced.

摘要： PURPOSE:To economize the quantity of the reinforcing steel members by supporting a long span truss beam between pillars and joining a steel member installed at the edge part which springs-out from each supporting point with an anchor member embedded under the ground and tightly joining the truss beam and the pillar. CONSTITUTION:A long span reinforcing steel truss beam 1 is supported on the reinforcing steel or concrete pillars 2 and 2' throught pins and rollers, and both the edge parts are sprung out from each supporting point. Then, earth anchors 3 are embedded and fixed into the ground. Then, a steel member 4 is installed in the lower part at the spring-out edge part of the truss beam 1, and the lower edge of the steel member 4 is installed on the earth anchor 3, and a pulling force T is applied on the steel member 4, and a prestress is applied on the truss beam 1. The truss beam 1 and pillars 2 and 2' are restrained by a knee brace 5, etc., and the pulling force T is released.

摘要： PURPOSE:To smoothly transmit stress by fixing a steelwork pillar pedestal part in a PC pillar in one body with a steelwork beam, and projecting the pedestal part from the upper end face of the PC pillar so as to join with an upper steelwork pillar. CONSTITUTION:The pedestal part 2 of a steelwork pillar B of an upper floor steelwork structure formed in one body with a steelwork beam 1 is fixed in a precast concrete pillar A of a reinforced concrete construction lower floor structure. The pedestal part 2 is projected from the upper end face of the precast concrete pillar A, and the projecting end part of the pedestal part 2 is joined with the steelwork pillar 3 of the upper floor structure through spliced plates 4 and high strength bolts 5. Consequently, stress of the steelwork pillar can be smoothly transmitted to the lower floor.

摘要： PURPOSE:To decrease stresses in and deformation of a trass beam and save the amount of steel material used, by supporting the steel-bone trass beam of a long span between pillars, and joining rigidly the beam with pillar in the condition that an upward directed force is given around the center of the beam. CONSTITUTION:One end of a steel-bone trass beam 1 with a long span is supported between pillars 2, 2 with a pin interposed, while the other end is supported alike with a roller interposed. In this condition, upward directed forces F, F are given around the center of the trass beam 1 using a jack or the like, and the trass beam 1 is joined rigidly with the pillars 2, 2, and prestress is introduced into the trass beam 1. This decreases deflection of the trass beam 1, and the amount of steel material used can be saved.

摘要： PURPOSE:To contrive tenacity reinforcing by placing concrete at crossed sections, after plane-crossed-frame-shaped band plates having the level of almost floor slab thickness are firmly fitted on the upper and lower respective flanges of beams at the crossed sections of the steel frame beams and RC columns. CONSTITUTION:Sections between the confronted sides of the frame pieces 3 of a closed type having the level of almost slab thickness are formed with band plates B connected to each other with reinforcing plates 4. After that, on the upper and lower respective flanges 1, 2 of beams A at the crossed positions of the steel frame beams 4 and RC columns D, the plates B and ribs 5 are fitted, and they are integrally formed. After that, hoops 7 are arranged between the webs 6 of the beams A, and after that, on column reinforcements 9 projected to the upper ends of the columns D, the reinforcements 7 and the plates B are fitted. Then, the concrete E of the fitted-on sections of slabs and columns is placed at the same time. As a result, the yield strength and tenacity of the jointed sections are increased, and the crack of the concrete, bearing pressure destruction, and joint separation between the jointed sections can be prevented from being generated.
