摘要： PROBLEM TO BE SOLVED: To provide a steel shell structure and the construction method thereof, which is constituted of steel plates as the outer shell and a T-shaped steel provided with projections welded with the inside face. SOLUTION: A T-shaped steel composed of the web having honey-combed notches in the crossing direction of a tunnel and a flange 21 provided with projections at the surface are welded with the inside face of steel plates forming the outside shell 1. The closed section is constituted of the lower floor slab steel shell in which an L-shaped steel 3 is welded with the outside shell 1 in the axial direction of the tunnel through the notch of the web, the upper floor slab steel shell, and the side wall steel shells. Screwed bar steels are inserted in bolt holes provided on the flange 21 face of the T-shaped steel 2, in the upper floor slab and the side wall steel shells to fix the middle part of the bar steel to the flange 21 with nuts. And nuts are fitted to the end of the outer shell of the bar steel and a steel form for placing concrete is detachably fitted to the opposite side end.

摘要： PROBLEM TO BE SOLVED: To provide a constructing method for a steel-concrete composite floor board bridge for use as a road bridge or a railroad bridge. SOLUTION: A floor board 26 made of steel, in which a plurality of bridge- axis members 14 integrally joining the bottom plate of a lower U-shaped steel sheet pile 11A with the main girder member 13 of an H-section are coupled to a plurality of upper U-shaped steel sheet piles 11B to increase the width of the floor board 26, and a frame member 17 comprising a half U-shaped steel sheet pile 15 joined with a side plate 16, are integrated together. After a cross girder member 18 is joined to the webs of the main girder member 13 and the side plate 16 by bolts or the like, cast-in-place concrete 21 is placed.

摘要： PROBLEM TO BE SOLVED: To prevent a crack of concrete by returning its height to the same height as a receiving stand of the other place after concrete is placed in a condition where outer shell sheet plate is made higher than the periphery. SOLUTION: When concrete is placed on a lower floorboard 5 of a synthetic structure caisson 1 composed of an outer shell steel plate 2 where T shape steel 7 having a projection is welded to the inside surface side and concrete 3 placed on the side to which the T shape steel 7 is welded, the concrete 3 is placed by holding a height of a receiving stand 12 of a part where an upper surface of the concrete 3 receives tensile force at supply time in a condition of being made higher than a receiving stand 11 of the other place. After the concrete 3 is hardened, the height of the receiving stand 12 is returned to the same height as the other receiving stand 11. Therefore, since prestress froce acts on a concrete surface by deflection of dead weight, when this prestress froce is offset to tensile force at supply time, a crack can be prevented.

摘要： PURPOSE:To enable the mass production of panel-assembled yards by using a flow production system by a method in which in constructing a marine structure by connecting panels, the assembling operation of panels is separated from the setting operation of panels, and only the constructing yard is set on the wharf for effectively using the wharf yard in order to advance the operations of each process in parallel. CONSTITUTION:In a yard for constructing a marine structure 1 by connecting panels 2a, 2b, 2c, 2d, and 2e, only the panel-constructed yard 5 is set on the position on the face of the wharf 12, and the panel-assembling yard 4 is separately provided on the back side. A truck on rails 6 and a winch are provided between both the yards 5 and 4.

摘要： PROBLEM TO BE SOLVED: To eliminate the joining work of a horizontal beam at a site and reduce transportation cost by assembling beforehand a bridge axial member and a frame member at a factory, joining a steel sheet pile at the site, and casting a cast-in-place concrete after inserting a PC steel material. SOLUTION: A steel panel 21, in which a bottom plate is composed of steel sheet piles 11 and a plurality of bridge axial members 14, in which H-section steels or CT-shape steels, as main beam members 13, are integrally joined together, are connected together, and a frame member 17, in which steel sheet piles 15 are made integral to side plate 16, are assembled and joined beforehand at a factory. And at the construction site, claws of steel sheet piles are integrally joined together and a PC steel material 18 is inserted into a hole of a web surface of the member 13 and side plate 16 and a horizontal beam 19 is precast, and thereafter a cast-in-place concrete 20 is placed. After the concrete 20 is cured, tension is imparted to the steel material 18 to ensure the rigidity in the direction normal to the bridge axis. As a result, manufacturing of horizontal beams and joining work at the site can be eliminated and steel sheet piles of required length only are transported and transportation cost can be reduced.

摘要： PROBLEM TO BE SOLVED: To improve an execution property by driving piles inserted in vertical legs and slant legs of a jacket construction into the water ground, and fitting insertion pipes provided on the legs of a bridge pier legs in the bridge support pipes formed by extending the vertical piles. SOLUTION: Vertical piles 14 and slant piles 15 are inserted into the vertical legs 11 and slant legs 12 of a jacket construction 16 to subsequently be driven in the water bottom ground 1 to constitute a jacket type foundation 10. In the next place, a pier 20 is secured on the pier support pipes 21 formed by extending the vertical piles 14 upward. In this case, steel insertion pipes 23 are set within the legs of the pier 20, and the legs of the pier 20 are fitted on the support pipe 21 via the insertion pipes 23, and then expansion mortar is filled within the space defined between the support pies 21 and the insertion pipes 23. Then, leakage prevention material is given in a connection between the vertical legs 11 and the insertion pipes 23 so as to prevent the support pipes 21 or the like from corroding. In this manner, lightweight can be achieved because of necessitating no footings, stability can also be improved, thereby shortening the construction period of time at great-water and deep water areas, or reducing the manufacturing costs thereof.
