摘要： PURPOSE:To reduce a construction period, construction cost and labor in the construction of an open-cut tunnel. CONSTITUTION:Reinforcing steel 6 formed of shape steel is fitted to the outer peripheral surface of extremely thin PC lining form plates 1, 1, 1', along the circular direction thereof through connecting steel 7, and supporting material for supporting the PC lining form plates is installed expandably by a jack along the arch shape of a tunnel to be constructed, thus forming a temporary bearing assembled frame 14. This temporary bearing assembled frame 14 is installed in the movable and travelable state at the invert part 13 of channel cross section of a tunnel lower half part constructed at the bottom part of the open-cut ground. In this temporary bearing assembled frame, the PC lining form plates are assembled in arch shape and fixedly placed on both side parts of the invert part 13, and the adjacent end parts of the reinforcing steel fitted to the PC lining form plates adjacent in the ring direction are jointed in the integrated state. After arranging a series of reinforcements 26 on the outer peripheral part of the PC lining form plates, an outer form 29 is assembled in arch shape on the outside of the reinforcements 26. Cast-in-place concrete is filled in a gap between the outer form and the PC lining form plates, and a process of removing the outer form after the curing-hardening of the concrete is performed continuously in regular succession by moving the temporary bearing assembled frame 14 forward.

摘要： PURPOSE:To excel in workability of connecting concrete segment to each other and maintain strength of the connected portions to more than a certain level. CONSTITUTION:Among a pair of connecting fitting bodies 2A, 2B, which are to be fitted to abuting ends 3, respectively, of adjoining concrete segments 1, a bolt inserting hole 4 is provided on the connecting portion of one connecting fitting body 2A and a female thread portion 8 is provided on the connecting portion of the other connecting body 2B. The bolt inserting hole 4 and the female thread portion 8 are then formed so as the bolt spiral direction, to which the bolt 9, after inserting into the bolt inserting hole 4, is to engage with the female thread portion 8, may face outward from the inside of the concrete segments 1 in a connected condition. The connecting portion of the other connecting fitting body 2A forms a washer 11 for the bolt head.

摘要： PURPOSE:To facilitate the inserting work of a bolt, and to enable automation and machinization without hindrance by fitting an elastic ring to the screw thread part of a bolt, so that a small clearance can be maintained between the bolt inserting hole and the thread ridges of the bolt. CONSTITUTION:A pipe 4 having a bolt-inserting hole 3 whose inside diameter is slightly larger than the inside diameter of the bolt-inserting hole 2 of a pressure-supporting plate 1 is arranged on the inside of the pressure-supporting plate 1 in the concrete of a segment A. Then, a bolt 6 fitted with an elastic ring 7 consisting of plastic or rubber or the like on its thread part is inserted into the bolt-inserting hole 3 of the pipe 4. A nut 5 is screwed on the bolt 6 in such a state that a small clearance has been maintained between the bolt- inserting hole 3 of the pipe 4 and the thread ridges of the bolt 6. Thereby, the bolt 6 can be positioned nearly in the center of the bolt-inserting hole 3, so that the dimensional error between the bolt-inserting holes 2 and 3 can be absorbed.

摘要： PURPOSE:To raise the strength of a fixing structure by a method in which a fixing sleeve with contracted opening end and the peripheral side of the end of a FRP tension member whose surface is subjected to a friction-increasing treatment are fixed under a pressed state by a quick-drying, expandible high- strength grout packed inside. CONSTITUTION:A synthetic resin rod 1 reinforced with carbon fiber, etc., is wound with a cynthetic resin reinforcing filaments or tapes in a spiral form, and the surface is subjected to a friction-increasing treatment. The inner surface of a fixing sleeve 2 having a contracted cylindrical opening 3 on its one end is subjected to a friction-increasing treatment. The fixing end of the rol 1 is inserted into the sleeve 2 and a quick-setting, expandible high-strength hydraulic group 4 is packed into the space between the periphery of the rod 1 and the inner surface of the sleeve 2. The inner surface of the sleeve 2 and the peripheral side of the rod 1 integrated by high inner pressure. High-strength connection can thus be obtained in a short time.

摘要： PURPOSE:To improve strength against the tensile force of bolt by a method in which a narrow and long joint end plate having a bolt-through hole in the widthwise central part is provided, and a narrow and long arched plate part curved backwards across between the bases of anchor-fitting parts is integrally provided. CONSTITUTION:A joint end plate 2 is of a narrow and long form to make up the front face of a joint metal 1, having a bolt-through hole 3 in its widthwise central part. Anchor-fitting parts 5 are integrally formed on left- and right ends of the plate 2, and the part 5 is of a backwardly projected cylinder form, having an anchor-fitting threaded hole 6 opening in the back end. An arched plate 7 is integrally provided across the bases of the parts 5 in a backwardly curved small and long form. Anchor reinforcing bars 10 are thrust through the holes 6.
