摘要： PROBLEM TO BE SOLVED: To divert a supporting girder to some other purpose, eliminate the lateral movement of the supporting girder, reduce a casting amount of concrete at one time and to enable a supporting to make a small-scale. SOLUTION: A supporting girder 19, hanging girders 23, two forms 21, etc., used in the case a horizontal beam is constructed are conveyed to specific sites of a tower column 5, the supporting girder 19 is built upward of the site in which the horizontal beam is built, a plurality of hanging girders 23 are extended to the supporting girder 19, and the forms 21 are hung on different hanging girders 23 respectively. The forms 21 cover the sides and bottom of the horizontal beam to have the openable bottom. The forms 21 are moved to both ends of the tower column 5, and a constitutive block 8 (8c) projected to the inside of each of the forms 21 in the direction of the inside between tower columns 5 is constructed by dividing into several times to erect the horizontal beam between the tower columns 5. The bottom of each of the forms 21 is opened, the inside thereof vertically passes through, and the forms 21 pass through both outsides of the constructed horizontal beam and are moved to specific sites in which the following horizontal beam is erected.

摘要： PROBLEM TO BE SOLVED: To provide a clamp capable of easily checking the lowering of tightening force. SOLUTION: This clamp is provided with a cover part 4 being free of opening or closing to a clamp body 3, and tightening takes place by way of screwing a nut 12 into a clamping shaft 9 piercing through each clamping part of the body 3 and the cover 4. The clamping shaft 9 has a spring seat 10, and in an interval between the spring seat 10 and a clamping part 7, there are a spring 11 being externally fitted in the clamping shaft 9 and a tightening force regulating member 13. If tightening force goes down due to the wire thinning of a clamped material, a clearance is made between the tightening force regulating member 13 and the spring seat 10, so that the lowering of the tightening force is easily recognizable.

摘要： PROBLEM TO BE SOLVED: To install a damping device even in a narrow space while reducing the construction period and cost and securely damp a bridge by dividing a bridge girder into bridge girder blocks having an appropriate length in the axial direction of the bridge and depressing the vibration of the girders by dampers installed between blocks. SOLUTION: Dampers made of highly attenuating rubber are installed at both outsides of a bridge girder 6 and adjacent bridge girder blocks 1 are connected together through the damper. In this time, a damping action caused by the dampers is easily obtained by the FEM eigen value analysis on the basis of the viscous attenuation of a single damper and the number of installed dampers. The dampers effectively function even when a relatively warped displacement or a tortional displacement has arisen and attenuates the bridge girders 6. When the bridge girders 6 vibrates by wind, the girders 6 are restricted by both main towers and the displacement of the bridge girder 6 is small at the vicinity of the main towers and maximal in the vicinity of the central part of the span. In this way, many days are not required for development and design and the bridge is securely attenuated by the installed dampers and further the dampers can be installed even in a narrow space.

摘要： PROBLEM TO BE SOLVED: To improve wind resisting damping operation of a bridge beam during erection of a suspension bridge. SOLUTION: A pair of right and left main cables 2a and 2b, the central part in the direction of a lateral width of a bridge beam 1 and the end parts on both sides thereof are interconnected through a pair of right and left oblique materials 4a and 4b and a pair of vertical materials 3a and 3b. The main cables 2a and 2b and the bridge beam 1 are integrally formed, a flutter oscillation velocity of wind is increased by improvement of twist rigidity and the additional mass effect of the main cables 2a and 2b, and a damping effect during blow down wind is improved.

摘要： PROBLEM TO BE SOLVED: To provide a transfer platform having core adjusting mechanism capable of smoothly traveling without providing any hindrance to obstacle existing upward/downward of a bridge capable, promoting controllability of the movement of a lapping machine and stabilizing winding efficiency. SOLUTION: An outside frame 9 and an inside frame 10 are capable of being moved along a bridge cable and being fixed to the cable, and both outside and inside frames are formed in a frame body capable of moving without coming into contact with cable band, hanger rope and hand rope post mounted on the cable band. A traveling frame 11 is provided to the inside frame 10 in a movable manner in the vertical direction, and a lapping machine 8 is mounted to the traveling frame 11 through a machine frame. The movement of the whole core adjusting mechanism loaded transfer platform 1 is made by altanating pitch movement between the outside frame 9 and inside frame 10, and the winding of a corrosion-proofing metal wire is made by traveling the traveling frame 11 during the stop of the outside frame 9 and the inside frame 10.
