摘要： PROBLEM TO BE SOLVED: To support loads well in a fire so as to reduce or eliminate a fire resistant cover by providing a diaphragm arranged at each junctions of joists with threaded reinforcing bars extending along the direction of the axis of a steel-pipe concrete structure column, the diaphragm being placed at each beam junction. SOLUTION: A plurality of threaded reinforcing bars 4 are arranged vertically and secured to a diaphragm 7 by nuts 9. The threaded reinforcing bars 4 are connected together by couplers 10 and are arranged continuously along the direction of the axis of a steel pipe 2. In each of diaphragms 7 placed at two of upper and lower places at each junction 6, four through holes 8 are formed. Concrete 3 is placed and packed ion the steel pipe 3 to construct a concrete structure column 1. No threaded reinforcing bars 4 may be placed between the diaphragm 7 above the junction 6 and the diaphragm 7 below the junction 6. Thus even in the event of a fire while no fire resistant cover exists, cracking and the width of a crack can be reduced. Therefore, either the fire resistant cover can be reduced or no fire resistant cover is required.

摘要： PURPOSE:To eliminate the needs for rust-preventing treatment for strands and also for the use of sheath material by a method in which a pair of couplers are set in a mutually facing manner and high-strength, corrosion-resistant, and flexible strands are engaged with the arms of the couplers to assemble an anchor. CONSTITUTION:A pair of couplers 2 and 3 are set in a mutually facing manner, and high-strength, corrosion-resistant, and flexible strands 1 of small-diameter resin-derived carbon fiber, etc., not metal are engaged with the arms of the couplers 2 and 3 with several turns to assemble an anchor. The anchor is penetrated into an anchor hole 4 and grout 5 is injected into the hole 4 to fix the tip of the anchor to the natural ground. After the grout 5 hardens, bolts 22 are thrust through a distribution plate 6, and the plate 6 is attached to the inlet of the hole 4 and screwed with nuts 23 in such a way as to introduce a given tension force into the strand 1. The bolt 22 is then fixed with the nuts 23.

摘要： PROBLEM TO BE SOLVED: To favorably prevent leakage of flame and smoke from a clearance and spreading to other sections due to collapse of the supper end of a partition wall or the clearance formed between a column and the partition wall, even if the allowable temperature of a steel material becomes higher than the present 350 deg.C by deregulation. SOLUTION: This fitting structure of the partition wall 1 fitted to the column and a girder 3a of a building and partitioning the inside of the building is provided with a girder deformation absorbing means 80 absorbing the deformation of the girder 3a to the side the partition wall 1 in the fitting portion between the partition wall 1 and the girder 3a, and a column deformation absorbing means absorbing the deformation of the column to a side separating from the partition wall 1 in the fitting portion between the partition wall 1 and the column.

摘要： PROBLEM TO BE SOLVED: To reduce fireproof covering of a steel pipe or establish a steel pipe equipped without a fireproof covering by introducing such an arrangement that the load in axial direction applied in the event of fire can be supported in good performance even in the condition without fireproof covering. SOLUTION: A concrete structure column 1 of filled steel pipe is structured so that a tremie pipe 4 extending in the axial direction of steel pipe 2 is embedded in the concrete 3 put fully in the steel pipe 2 having a square/rectangular section. The tremie pipe 4 serves both for placing concrete and reinforcement of the concrete. At one side in circumferential direction of this tremie pipe 4 a plurality of holes 5a are formed at a constant spacing in the axial direction, and at the other side of tremie pipe 4 180deg. apart in the circumferential direction from the holes 5a, a plurality of holes 5b are formed at a constant spacing in the axial direction being positioned approx. in the middle between the holes 5a, 5a adjoining above and below.
