摘要： PURPOSE:To prevent electrical troubles and corrosion of reinforcing steel rods, by using reinforcing steel rods coated with an electric insulating material like epoxyresin on steel bars made of non-magnetic materials like high manganese steel to form a structure. CONSTITUTION:An insulated steel rod coated with an electrical insulating material 22 like epoxyresin is formed on a non-magnetic steel bar 21 made of non- magnetic materials like high manganese steel, stainless steel, etc. The electric insulating steel rods 20 are arranged inside a reinforced concrete structure 10. The main reinforcing bars 11 are bundled with distributing bars 12 by insulating clips 13 to fix them. And insulating joints 14 like sleeve joints, screw joints, etc., made of high manganese steel or the like are used for the joints of the distributing bars 14. In this way, electric troubles brought in various appliances and corrosion of the reinforcing bars can be prevented.

摘要： PROBLEM TO BE SOLVED: To prevent electric shock accident by ensuring the soundness of ground system for electric facility in an insulated building employing reinforced plastic reinforcing rods. SOLUTION: A concrete building 11 employs nonmagnetic and nonconductive reinforced plastic reinforcing rods 12 in place of iron rods. The earth wire 24 of an electric facility 13 installed in the concrete building 11 is connected with a detector 25 comprising a current detector 27 for measuring the leakage current of electric facility 13, and a potential detector 28 for measuring the ground potential of electric facility 13. Detection results are outputted to a central supervisory section 32. The central supervisory section 32 analyzes the soundness of grounding in the electric facility 13 and takes a safety measure, e.g. delivers an alarm or interrupt the power supply to the electric facility 13, when the soundness of grounding deteriorates below a predetermined reference level.

摘要： PURPOSE:To reduce a structure vibration due to an earthquake or the like by arranging a plurality of air spring devices made of movable steel tubes sealing the high pressure air on a structure and the foundation thereof in a horizontal direction, and stacking a plurality of the devices in a vertical direction. CONSTITUTION:The horizontal vibration component of a structure foundation due to an earthquake or the like is prevented from being transmitted to a structure by the help of the shearing deformation of a laminated rubber body 4 having restitutive force. On the other hand, the vertical vibration component of the foundation is prevented from being transmitted to the structure, using stacked air spring devices 5 made of movable metal tubes 6. Furthermore, each tube 6 is internally connected to an auxiliary tank via a valve 42 having orifice function, and the vertical vibration component is attenuated with the travel resistance of the air flowing through the valve 42. In this case, if the internal pressure of the tube 6 drops below a preset value, due to an air leakage or the like, a compressor is operated to maintain the pressure at the value.

摘要： PURPOSE: To obtain a measuring method in which the cross-linking progress state of an uncross-linked rubber can be measured by a method wherein one pair of specific steels plates out of a plurality of internal steel plates which support uncross-linked laminated rubber are used as electrodes, a cycle voltage is applied and an electrical characteristic value is detected. CONSTITUTION: Sheetlike unvulcanized rubber and steel plates 14 to 18 are arranged alternately inside a mold 20 which has been preheated to the vulcanizing temperature of the rubbers, and an axial-direction load is applied to the sheetlike unvulcanized rubber and the steel plates 14 to 18 by an upper plate 41 and a push plate 43 by means of a press machine 50. The laminated rubber 13 which are arranged in the mold 20 raise their temperature with the passage of time so as to reach the vulcanizing temperature, of the rubber, which is the same temperature as the mold. Thereby, as the cross-linking reaction of the laminated rubbers 13 progresses, an electrical AC resistance value is raised once, it is then lowered, and it then displays a constant value. This indicates a point of time in which the time change rate of an AC resistance becomes nearly zero, and it is a point of time in which the cross- linking reaction of the laminated rubber 13 has been completed. Consequently, when a change in the time change rate of the electrical AC resistance is traced, the progress degree of the cross-linking reaction of the rubber can be observed.
