摘要： PURPOSE: To provide a slab in a well integrated form with more strength by placing postplacement concrete on a ribbed PC plate with a rib portion protruded vertically and laterally on the upper face and further on the upper face thereof on the rib portion side into an integrated structure. CONSTITUTION: A slab is integrally formed in combination with postplacement concrete 3 placed on a ribbed PC plate 2. The ribbed PC plate 2 is formed with reinforcing bars 2b uniformly arranged at the bottom of the ribbed PC plate 2 so as to be strongly proof against bending tensile stress. With the reinforcing bars 2b intensively arranged at a rib portion 2a, one type of beam structure is formed to which further strong rigidity is granted to reduce by half the thickness D of the bottom base of the PC plate.

摘要： PURPOSE: To improve economy by integrating the reinforcing bar of a strut that is left in the building frame structure of a building among covering body materials in the main construction of such building as a reactor building into a complex in concrete for composing an earthquake resisting wall. CONSTITUTION: A covering body consisting of a strut 6, a wall 7, a roof dome 5, and the like is tentatively installed to enable an all-weather construction when performing the main construction of a building 1 such as a reactor building. The strut 6 is composed by arranging a number of shear resistance materials 63 due to rib-shaped steel that is welded horizontally over both flanges 61 and a web 62 of a steel frame 60. Then, even after the covering body is removed, only the strut 6 is left in the building frame structure of the building 1 and is buried into concrete 70. As a result, the strut 6 is considered as a total reinforcement type member and can be evaluated in structure design.

摘要： PURPOSE:To remarkably reduce arranging works of reinforcing rods of walls at site, by forming a cotter at the inner periphery of a half-precast wall plate and previously arranging bearing rods inward the plate. CONSTITUTION:A half-precast wall plate 2 is previously manufactured in a fabricator. At that time, a taper slanting toward the inside is formed at the whole periphery of a small opening 2a and recessed cotters 4, 4' are formed every specified interval at both that small openings 2a and inner periphery. The inside is constituted so as to arrange the bearing rods 5 composed of vertical rods 5a and horizontal rods 5b. As a result, since the half-precast wall plate and subsequently placed concrete become securely a solid unit to constitute a sturdy bearing wall, the whole wall thickness including the half-precast wall plate becomes an effective wall thickness resisting against the earthquake force. In this way, it becomes unnecessary to arrange plenty of thick bearing rods in the subsequently placed concrete on the site operation and hence, the arrangement work of reinforced rods in a wall at the site can be remarkably reduced.

摘要： PURPOSE:To shorten the period of construction by a method in which two PC plates are set at a given interval by facing each other, reinforcing bars are set between the PC plates, and concrete is placed into the space between the PC plates. CONSTITUTION:Two PC plates 2 each of which is divided horizontally are set by facing each other at a given interval S and horizontal and vertical reinforcing bars 2a and 3 are arranged on the insides of the divided PC plates 2. A notch 2b tapered in the direction of parting line L of V-groove and a cotter 2c formed by intermittently cutting the notch 2b are provided to the PC plate 2. Concrete 4 is placed into the space between PC plates 2 to form an integrated wall structure of thickness T. The strong thick wall 1 can thus be constructed.

摘要： PURPOSE:To enable a removal of a large sized nuclear reactor, by constructing a temporary tank and a tank at an inside and an outside of a reactor building, respectively, and by transporting a main body of the nuclear reactor cut off from a structural body of the building in a floating condition on a liquid in each tank. CONSTITUTION:In a building 1, a liquid W0 is fed into a temporary tank, and then a main body 10 of a nuclear reactor is cut off in a water of a lower foundation 2 part, at a hung-down condition of the reactor by jacks 32. After that, the main body 10 is put down onto a carriage 35 stationed on rails 33 by disengaging the hung-down condition by the jacks 32 and, at the same time, water is fed into an inter-mediate tank 41 to raise its water level to the same level W1 as that of the tank 30. Then, after pulling up a water gate 91, the main body 10 is transported to the tank 41 by the carriage 35 and water W0 in the tanks 30 and 41 flows into a treatment tank 42 to make its water level be a level W2, by pulling up a water gate 44. Moreover, after transferring the main body 10 into a tank 42, a water gate 45 is pulled up and therewith the liquid W0 in the tank 42 flows out into a discharge tank 43 and the main body 10 settles down to a floor in the tank 42. After those procedures, the liquid W0 is solidified and, buried for ever with the main body 10.

摘要： PURPOSE:To simulate the stress distribution of a fixed border slab corresponding to actual machine design by fixing the periphery of a test body on a force application base, setting a load applied on a force application point according to the relation between force application points, and applying a uniformly distributed load by a hydraulic jack. CONSTITUTION:Four sides of the test body A on the force application base 1 are fixed by a PC steel material 6, the hydraulic jack 4 is arranged by a support frame 9 closely to the center part of the test body, and the uniformly distributed load P is placed on the test body with the reaction force of a reaction beam 3 through the operation of the jack 4. The ratio of respective loads is so set that P1:P2:P3=1:2:3. The device consists of the base 1, a pole 2, and the beam 3, so the device becomes compact and a self-balancing system whose column is buried in the base does not require a reaction force floor and the periphery of the test body is fixed to set peripheral border condition and when the stress distribution at the time of multipoint force application is a uniformly distributed load corresponding to actual machine design, the stress distribution of the fixed border slab can be simulated.
