摘要： PROBLEM TO BE SOLVED: To efficiently secure the fire resisting performance of base isolation members at the time of mounting the base isolation members in a building and at the time of maintenance and inspection of the same.
SOLUTION: According to the fire compartment structure an intermediate story of the building is constructed as a base-isolation story on which a combustible F and columns 10 each having the base isolation member 30 mounted therein. A combustible existing space S1 in which the combustible F exists, is isolated from a base isolation member installation space S2 in which the columns 10 each having the base isolation member 30 are mounted, by a fire resisting member 50, and therefore without fire-resisting covering for each base isolation member 30, the plurality of base isolation members 30 are enclosed by the fire compartment in a lump in the base isolation member installation space S2. In this manner the fire resisting performance of the base isolation device is secured as a whole.

摘要： PROBLEM TO BE SOLVED: To provide a fire resisting structure for a base isolator formed of a plurality of base isolation members, wherein the base isolation members are set up according to systematic fire resisting technique.
SOLUTION: According to the fire resisting structure, a laminated rubber base isolation member 20 is interposed between a lower column section 10a and an upper column section 10b, and the fire resisting member 14 is erected from the lower column section 10a in a manner enclosing the rubber laminated base isolation member 20. Further an inter-column base isolation slit 15 is formed between an upper edge of the fire resisting member 14 and the upper column section 10b. In the same manner a fire resisting wall 30 such as an outer wall on the periphery of the columns, is formed of a lower wall section 30a and an upper wall section 30b, and an inter-wall base isolation slit 31 is formed between the wall sections. Further the same slit joint member 50 is inserted into each of the inter-column base isolation slit 15 and the inter-wall base isolation slit 31.

摘要： PROBLEM TO BE SOLVED: To provide a strong column-to-bean joint part while reducing construction cost by using surrounding plates as structural members and securing the adhesive performance of column main reinforcements in a method of constructing the column-to-beam joint part by surrounding plates.
SOLUTION: Two S-beams 12 extend through an RC column 14 at the column-to-beam joint part 10. The RC column 14 is rectangular in cross section. The two S-beams 12 cross perpendicular to each other at the center of the cross section of the RC column 14. The two S-beams 12 extend through the RC column 14 at the centers of the four side surfaces. A steel surrounding plate 22 welded to the S-beam 12 to form four side-surfaces of the RC column 22 is installed at the column-to-beam part 10. Vertically extending column main reinforcements 30 extend through the RC column 22 demarcated by the four corners 22A of the surrounding plates 22 and two S-beams 12 facing the inside of the corners 22A. The portion thereof where the column main reinforcements 30 are positioned on the inside of the surrounding plate is formed as a spiral reinforcement 30A.

摘要： PROBLEM TO BE SOLVED: To place downward structural bodies by turns and secure the impervious property and increase the workability, by transferring stresses between precast and postcast parts by the frictional forces brought at the vertical face of the placing joint closely and continuously constructed between these parts. SOLUTION: A form for molding the vertical face 1a of the placing joint is used for the bottom form of the down concrete at the first floor above the ground as a precast concrete part. Concrete is placed therein to construct the precast concrete part 1. After the first basement floor 3 has been constructed, the bottom form of the precast part 1 is disassembled and the rising concrete as the postcast part is placed. In this case, on forming the placing joint between the precast part 1 and the postcast part 4, airvent holes are arranged in the precast part 1 and the bottom of the protruded part is tilted to turn to the air vent to accelerate exhausting of air and prevent air from stagnating in the placing joint. And also when the postcast concrete settles dot, it prevents clearances at the vertical placing joint in the earth retaining wall. In this way, the shearing force in the plane and impervious property are secured and the workability and economical efficiency are improved.

摘要： PURPOSE:To ease joining of reinforced concrete beams, which are divided into a plurality of parts, by providing a shell plate, on the inner surface of which stub-dowels are planted, in such a manner that it strides across a space between neighboring beams together with placing concrete thereon. CONSTITUTION:A steel shell plate 1 for joining is formed into a letter of U, and stud-dowels 2, which transmit tensile stress occurring in beam-bottom, reinforcing bars 5, are planted on the inner surface of the shell plate 1. Then, the shell plate 1 is positioned flushed with beam-formworks for neighboring, reinforced concrete, so that the shell plate strides across the space between the neighboring beams. The number and the diameter of the stud-dowels are determined each time, according to the intensity of the stress. Next, concrete 4 is placed on both formwork and shell plate 1. Then, the shell plate 1 is covered with fire-proofing 3, and an upper-end, main reinforcements 6 are overlapped with each other and joined by pressure welding, thereby integrating a slab 8 into one body. With this contrivance, a plurality of beams can easily be joined without pressure-welding the beam-bottom, reinforcing bars 5.

摘要： PROBLEM TO BE SOLVED: To provide an erection method of a reinforcing bar to a pile head end plate of the prefabricated concrete pile capable of simply and surely erecting the reinforcing bar on the pile head end plate at a comfortable posture. SOLUTION: A nut 36 is previously screwed on a male screw 34 of the reinforcing bar 14. A male screw 32 of the lower end of the reinforcing bar 14 is pushed into a screw hole 22 of the pile head end plate 20 in the pile head end plate 20 of a pile head 12A of the prefabricated concrete pile 12. The screwing-in work is carried out by manual operation at the extent to enable an erection state to the pile head end plate 20 to maintain. A power fastener 40 such as an electric impact wrench or the like is used to engage a nut engaging section 40A of the power fastener 40 with the nut 36, and the reinforcing bar 14 is rotated by the power fastener 40 while paying attention to vertical accuracy to screw the male screw 32 of the reinforcing bar 14 on the screw hole 22.
