In the length direction, a large number of horizontal tightening PC materials 13 are placed in the tact 1.
0 and tighten to secure it. Further, like the reinforcing member 4, the PCC 6013 consists of a fiber bundle 2 made up of a large number of fibers 1 that are not aligned, and each fiber 1 is bound by a resin material 3. In addition, unbonded PC materials that are not coated with asphalt or tar because concrete does not adhere to them, or boss-tensioned materials that use a sheath may be used as appropriate.For high-strength lightweight concrete, fiber-reinforced concrete may be used. Good too. The high-strength lightweight concrete arch unit may also be formed into a polyhedral structure with a cross-sectional shape or polygonal shape. Furthermore, in the above embodiment, split-shaped arch-shaped units were used as a pair, and they were butted together in the curved direction and tied together at the top. It may be tightened in the direction. Further, carbon fibers and glass fibers are suitable as the fibers 1 constituting the reinforcing member 4 and PCC6013, but other synthetic resin fibers, ceramic fibers, metal fibers, etc. may also be used, and these fibers may also be used. May be used in combination.

As the resin material 3, vinyl ester resin, unsaturated polyester resin, epoxy resin, phenol resin, etc. are used. Regarding the manufacturing method, the fiber bundles 2 of the longitudinal component and the constituent components are woven or arranged in a lattice shape, and sufficient tension is applied to maintain linearity while impregnating the resin material 3, and then heat treatment is performed to reduce the viscosity of the resin. After that, it is molded into an arch shape by applying pressure and hardened by heating.

全体の重量を軽減することができる。In this way, the prefabricated PC shelter is made of an arch-shaped reinforcing member in which fiber bundles 2 made up of a large number of aligned fibers 1 cross each other to form a lattice shape, and each fiber 1 is bound by a resin material 3. The high-strength lightweight concrete arch-shaped unit 7 reinforced with the reinforcement member 4 and the PC material 13 are tightened together with the reinforcement member 4 and the PC material 13 for horizontal tightening.
There is no need to worry about corrosion of C6013, and there is no difference in level between the vertical component of the lattice of the reinforcing member 4 and the component, so the concrete cover thickness can be reduced.

The high-strength lightweight concrete is discharged into a hopper waiting at the discharge port, and then transported to the hopper port located at the top of the arched formwork by a lane running through the hopper, and then transported from the hopper port into the formwork. This process is then repeated to place concrete. In addition, high-strength lightweight concrete has a unit weight of 1.5 to 1.8 t/m3 and a compressive strength of 4.
00kg/aJ or more, it is about 2/3 lighter than a prefabricated PC shelter made of ordinary concrete, and even lighter reinforcing members 4 and PCC6013
In addition to reducing the overlay thickness, the thickness of the parts can be made thinner, resulting in further weight reduction, making it possible to install prefabricated PC shelters in places with relatively low foundation support capacity, such as bridges, viaducts, and urban areas. be.
