摘要： PURPOSE:To install PCa floor slabs on a beam definitely and accurately only by positioning, and joint the PCa floor slab with the beam and the PCa floor slabs with one another without such a trouble as a welding procedure. CONSTITUTION:A large number of studs 16 are projectingly installed on the top of large beams 12a and 12b in a row with a specified spacing in the longitudinal direction while positioning generation holes 20, which are largersized than the studs 16 and placed with a spacing equivalent to the row of the studs 16, are vertically bored on a beam installation site of the PCa floor slabs 18. When the PCa floor slabs 18 are to be installed on the beams, each of the positioning holes 20 are installed to the large beams 12a and 12b, penetrating through the studs. Then, mortar or concrete-made filter-material is filled-up in a cavity area of the positioning hole 20.

CONSTITUTION:In a joint method which installs a pair of PCa floor slabs as opposed and joints the paired floor slabs with a beam 10, holding studs 16 in between, on both sides of the top of the structural steel beam 10 which is located at the center of the tip and from which a large number of studs 16 are projected in the longitudinal direction, a plurality of vertical loop-shaped U reinforcements 14 are projectingly installed while the U-shaped reinforcements are arranged so that each of their tips may approach alternately the opposed PCa floor stab, crossing over the studs. After the installation of both PCa floor slabs, at least a pair of reinforcing bars are placed and tied-up, intersecting and in parallel with each of U-shaped reinforcing bars 14 on both sides of the studs 16. Then, mortar or concrete 22 is filled-up in a groove 12a formed between both PCa floor slabs 12.

摘要： PURPOSE:To prevent reinforced material from early breaking by bending a bar-shaped body which is obtained by collecting, bundling and hardening high strength fiber with thermoplastic resin in point symmetry, and cutting it at a point symmetrical position to form the reinforced material. CONSTITUTION:Reinforced material 1 formed of high strength fiber collected, bundled and hardened by using thermoplastic resin is heated to soften. After that, a form of the reinforced material bent to approximate 90 deg.C at a specific radius of curvature is made in a state to couple two parts with each other at point symmetry. Then, after it is cooled to harden again, it is cut at a point symmetrical position to form two reinforced materials 1. Residual force is mutually offset at a site making a point symmetry to each other to reduce residual stress.

摘要： PURPOSE:To obtain a precast concrete pillar having the high strength and the superior fireproofness by embedding a fibrous member into a concrete hollow cylinder body, reinforcing the hollow cylindrical body and convering the outer periphery of the hollow cylindrical body by a fireproof member. CONSTITUTION:A concrete pillar body is constituted of a concrete hollow cylinder body 1, fibrous body 2, and a fireproof covering member 3. The concrete hollow cylinder body 1 is shaped from a cylindrical body having opened port parts A at the upper and lower edges through the centrifugal molding method. Further, the fibrous body 2 is formed by forming the fibrous material such as carbon fiber and aramid fiber to a mesh form and attaching the meshed body by an adhesive such as epoxy resin. Further, the fireproof covering member 3 is made of the fireproof material such as ceramics. Then, the fibrous body 2 is embedded into the thick part of the cylindrical body 1, and concrete is placed, and further, the outer peripheral part is covered by the fireproof material 3. Accordingly, the pillar having the high strength and the superior fireproofness can be obtained.

摘要： PURPOSE:To obtain an earthquake resisting structure in good reinforcing efficiency by providing a steel frame member attached to right and left or upper and lower symmetrical positions in an opening part, rigidly connecting to the steel frame member one end of an elastically plasticized shearing panel and pin-connecting to a brace, pin-connected to a structural body, the other end of the panel. CONSTITUTION:A frame member 4 of H-shaped steel, fixed by a stud bolt, is provided along a pillar 1 in a tetragonal opening part 3 surrounded by the RC-made pillars 1 and beams 2. Next the frame member 4 horizontally fixes to its vertical directional intermediate position a shear panel 5 pin-connecting to its protruding end part a brace 6 constituted in length almost equal to height of the opening part 3. The brace 6 is vertically positioned and pin-connected to gusset plates 7 fixed in their respective end parts to the upper and lower side beams 2 and 2a. In this way, execution work is facilitated, and its term and expense can be reduced by efficiently performing reinforcement possible to be mutually interpolated.

摘要： PURPOSE:To provide a thin and strong PS slab by arranging supporting members such as roller in such a way as mating with the two ends of a form, setting a tensioning member over them, tracing one of the ends for giving a tension, and then placing concrete. CONSTITUTION:Supporting members 3 such as roller etc. 5 are arranged in such a way as mating with the two ends of a form 1 on its concrete placing surface side. Between these supporting members 3 a tensioning member consisting of reinforcing fibers such as carbon long filament 2. Aramid fiber, vinylon fiber is set over meanderingly. Upon tracting one of the ends to introduce tension to the tensioning member, concrete 9 is placed. This allows giving a tension without risk of causing friction to the fibers.
