摘要： PROBLEM TO BE SOLVED: To improve the strength by providing an H-shaped member which is attached to an end part joint part of a segment and with which flange faces come in contact mutually and connection bolt which passes through flanges of the H shaped member and tightens them mutually in a joint part. SOLUTION: H-shaped members 2a, 2b are attested to end parts of adjacent segments 1a, 1b, respectively, and the H-shaped members 2a, 2b are attached in such a manner that flanges 3, 3 come in contact with flange outer faces mutually adjacent H-shaped members. The H-shaped members 2a, 2b are provided with a hole through which four flanges pass and many bolts 4 which pass through this hole and bind the H-shaped members. For this reason, this joint structure is a simple structure and becomes a powerful joint for pulling and bending. As the H-shaped member, H-shape steel which is a standardized product may be used, or a plate and a member having T-character cross section may be used in accordance with the strength of a joint. Consequently, it is possible to improve the strength and correspond to severe conditions by providing the joint of the segment and a structure which uses the H-shaped member.

摘要： PROBLEM TO BE SOLVED: To ensure transmission of a uniform stress between a pile and an upper frame structure without using a reinforcing rib by extending an upper surface of a pile from the whole circumference of outer diameter surface of head of the pile to a sideward direction over the outer diameter of the head of the pile by a specified length or more, and specifying the thickness of wall of abutting part of fitting part of the upper frame structure. SOLUTION: An extending amount of a pile 2 from the outer circumference of a head thereof is made 100 mm or more from an outer diameter D of an upper part of the pile 2, on the whole circumference. The plate thickness of a base 1 is set to have a minimum value H2 of not less than 75 mm, and the base 1 is fomed by machining a steel plate or made of cast steel. A part or the whole positioned in a circle with a smaller radius by 100 mm than a radius of an outer diamter surface of the pile 2 is opened with a thin wall or upward/downward. In this case, the base 1 is used as a connection member, and even if there is a horizontal eccentricity between the head of th pile 2 and the fitting steel pipe 3 the connection between the two 2, 3 are made possible without using a reinforcing member. Accordingly, on-site welding is reduced than a conventional method, thereby reducing the work period and cost, as well as reducing the amount of on-site welding resulting in improvement of quality in the connection part.

摘要： PROBLEM TO BE SOLVED: To simplify installation and movement, and to make a moving working platform for construction works economical by a method wherein covering plates are spread all over the surface of a lattice frame formed by assembling steel materials and the working platform is constituted, travel devices are mounted to lower sections in the vicinity of both ends of main girders configuring the outer circumference of the lattice frame, and parts of wheels can be driven. SOLUTION: This working platform 1 is constituted by spreading covering plates all over the surface of a lattice frame formed by assembling steel materials, travel devices 2 are installed to lower sections in the vicinity of both ends of parallel main girders 11 on an outer circumference, and driver's cabs 14 and ladders 15 for lifting and lowering are set up at the four comers of the lattice frame. Since wheels mounted on the travel devices 2 are crossed and placed on rails 3 installed at the top sections of sheet piles 4, the moving working platform can travel in the direction of the flow of a river. Rail clamps 27 for holding at the time of stoppage and buffers 28 for collision prevention are set up. Since a drive mechanism is configured of a hydraulic motor and a speed reducer and drives the wheels of trucks and a bogie mechanism permits rotation in the horizontal planes of the trucks, the working platform can travel so far as a section between the rails is kept constant.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of a level difference due to the subsidence of ground at the boundary by filling a predetermined number of block bodies between an excavated surface and a road structure with an enlarged width, laying crushed stone on the top of block bodies, and paving the top surface with paving materials. SOLUTION: Piles 2 are driven into a sloped surface 1 at the valley side closely to an existing road 8, lateral girders 3 are erected between the upper portions of the piles 2b thereby constructing supporting main bodies 17a, and a road shoulder portion of the existing road 8 is excavated. And one or two or more block bodies 12 each placed by filling a filler after assembling together precast concrete block pieces 14 to 16 to a cross section shaped to a reversed trapezoid are assembled in a space between the supporting body 17 and the excavated surface 11. After filling, a floor slab 4 is installed to the top of the supporting body 17, crushed stone 13 is laid on the block body 12, and the surface layer is paved to one united body with paving materials thereby building the road with enlarged width. Without backfilling with sediment, concrete is completely filled thereby ground settlement at the boundary jointing portion B can be prevented, the work can be done closely to the existing road 8, the period of time for the work can be shortened and the construction cost can be reduced.
