摘要： PROBLEM TO BE SOLVED: To prevent cracks of a reinforced concrete floor slab of a continuous beam of a bridge. SOLUTION: A steel main beam 3 is installed on the top of piers 1, 1', and a reinforced concrete floor plate 4 is formed on the upper surface and the middle upper surface of the steel main beam 3 excluding a beam end part upper surface 3'. By a downward force from a deflecting force-adding device 10 comprising an upper sheave 11 installed under a simple beam 2 formed with the steel main beam 3 and the reinforced concrete floor plate 4, lower sheaves 12, 12 installed under the piers 1, 1', wire ropes 13 hooked to them, and a wire rope pulling-in means 14 for pulling in these wire ropes 13, the simple beams 2, 2 are deflected so as to expand the upper clearance between the beam end faces 3c, 3c of adjacent simple beams 2, 2 and form a reinforced concrete lateral beam in that clearance. Then a connection part reinforced concrete floor plate 4 is formed with the reinforced concrete lateral beam and the beam end part upper surface 3' to cancel the downward force. Thus, because a prestressed force is introduced into the reinforced concrete floor plate 4, cracks will not occur.

摘要： PROBLEM TO BE SOLVED: To enable improvement of a flexural strength of the connecting part of a pier and a footing without impairing the strength of the footing, by a method wherein a reinforcing steel sheet reinforcing the pier and the footing of the foundation are made monolithic by encasing concrete. SOLUTION: Reinforcing steel sheets 7 are lined in the shape of a vertical tube surrounding a pier 1a formed of reinforcing bars 3 and concrete 4. A plurality of studs 8 are provided in projection on the outer peripheral surface of the lower part of the reinforcing steel sheets 7. A plurality of insertion bars 9 are planted on the upper side of a footing 2 formed of reinforcing bars 5 and concrete 6. Then, the studs 8 provided in projection on the reinforcing steel sheets 7 and the insertion bars 9 inserted into the upper side of the footing 2 are made monolithic by encasing concrete 10. Thereby the load in the axial direction of the reinforcing steel sheets 4 is transmitted to the footing 2.

摘要： PURPOSE:To simplify structure, to compact a balustrade and to enable containing of a balustrade without impeding driveway traffic by a method wherein a top rail pivotally supported to the upper end of a stay through a pin is rotated around a pin at the lower end of the stay and contained between containing foundations. CONSTITUTION:In a balustrade, a stay 3 is pivotally supported to a top rail 2, being usable as a road surface during containing, by means of a pin 4. The top rail is pivotally supported to a containing foundation 9 located on the side of a steel floor board surface 1 by means of a pin 5 located at the lower end of the stay. The stay is formed such that it can be caused to freely rise and fall through the function of a hydraulic cylinder. Rotation of the stay 3 around the pin 5 at the lower end of the stay causes change of the balustrade from a rising state during use to a falling state during containing of the balustrade thus containing the top rail 2 between containing foundations 9. In this case, the top rail 2 can be changed from a state to be used as the top rail to a state to be used as a driveway surface on which a plurality of lanes are continued to each other.

摘要： PURPOSE:To make mooring of a slide anchor even in a shallow water area possible in safety by installing a slide block, capable of sliding down due to its own weight, on a slope surface of a slope surface block having a slope at its upper side, and by connecting them with a body to a floating wave dissipation levee. CONSTITUTION:A slide anchor 02 is constructed of a slope-surfaced block 1, having a slope surface 1a at its upper side, and a slide block 2 that is mounted on the slope surface 1a in a way that it is capable of sliding down under water with its own weight. Then the slide anchor 02 is submerged and settled at a prescribed position with a cable body 03 tied at its one end to the slide block 2. The other end of the cable body 03 is connected to a floating wave dissipation levee 01. When an excessive load is applied to the cable body 03, the slide block 2 moves of the in the direction of the load, so that any stress more than a certain amount may not act on the cable body 03. Thereby desirable catenary characteristics can be displayed even in a shallow sea area.
