The reinforcing bar bridges 14 are the same as those of the reinforcing bar structural members 12a and 12b, and are arranged vertically separated by a predetermined dimension on the inner surface 19 of the steel plate base 13. The reinforcing bar bridge 14 is a fixed rod 25 that is separated forward from the inner surface 19 of the iron plate base 13 and extends linearly in the lateral direction, and a pair of fixed rods 25 that extend straight in the front-rear direction from both ends of the fixed rod 25 toward the iron plate base 13. It has a leg rod 26.

The leg rod 26 is inserted through the through hole 22 of the iron plate base 13, penetrates the iron plate base 13, is exposed (extended) rearward from the outer surface 20 of the iron plate base 13, and extends in the front-rear direction, and the iron plate base. It has a leg front portion 28 that is exposed (extended) forward from the inner surface 19 of 13 and extends in the front-rear direction. A screw (fixing means) is formed on the rear portion 27 of the leg. The front leg portion 28 is located between the inner surface 19 of the iron plate base 13 and the fixed rod 25. A narrowed portion 30 having a thickness smaller than that of the residual portion 29 of the front leg portion 28 (thickness is thinner than the residual portion 29) is formed at substantially the center of the front leg portion 28.

In the leg rod 26, the reinforcing bar bridge 14 is attached to the iron plate base 13 by screwing the nut 31 (fixing means) to the screw (fixing means) of the leg rear portion 27. In the leg rod 26, the narrowed portion 30 is broken by applying a force to the leg rear portion 27 so as to bend the leg front portion 28, whereby the leg front portion 27 is connected to the substantially front half and the leg rear portion 27.

The main reinforcing bar 15 including the upper end reinforcing bar 32, the lower end reinforcing bar 33, and the first and second lattice reinforcing bars 34 forms a reinforcing bar truss. The upper end reinforcing bar 32, the lower end reinforcing bar 33, and the first and second lattice reinforcing bars 34 are the same as those of the main reinforcing bars 15a and 15b of the reinforcing bar structural materials 12a and 12b.

The P-cone 16 is attached to the leg front portion 28 of the leg rod 26 and is located between the inner surface 19 of the plate-shaped base 13 and the fixed rod 25. A washer 38 inserted through the front leg 28 of the leg rod 26 is located at the top of the P cone 16. Inside the P-cone 16, a narrowed portion 30 formed in the front leg portion 28 of the leg rod 26 is located.

The external heat insulating material 50 (board-shaped heat insulating material) has a predetermined thickness dimension, has substantially the same area as the iron plate base, and is formed into a rectangular shape whose planar shape is long in the vertical direction. The external heat insulating material 50 is arranged outside the reinforcing bar structural material 12 (immediately before the upper end reinforcing bar 32). Extruded expanded polystyrene foam (styrofoam) (expanded plastic) is used for the external heat insulating material 50. In addition to the extruded polyethylene foam, polypropylene foam, phenolic foam, PET resin foam, or the like (foamed plastic) can also be used as the external heat insulating material 50.

In the reinforcing bar structural material 12, the washer 38 is inserted into the leg front portion 28 of the leg rod 26, and the P cone 16 is attached (inserted) to the leg front portion 28 to form a stenosis formed in the leg front portion 28 of the leg rod 26. After the portion 30 is positioned inside the P cone 16, the leg rear portion 27 of the leg rod 26 is inserted into the through hole 22 formed in the iron plate base 13. When the leg rear portion 27 is inserted into the through hole 22, the leg rear portion 27 of the leg rod 26 is exposed rearward from the outer surface 20 of the iron plate base 13, the top of the P cone 16 comes into contact with the washer 38, and the bottom of the P cone 16 is exposed. It abuts on the inner surface 19 of the iron plate base 13. The reinforcing bar structural material 12 is assembled by screwing the nut 31 to the leg rear portion 27 (screw) exposed on the outer surface 20 of the iron plate base 13 and attaching the reinforcing bar bridge 14 to the iron plate base 13.

The outer wall reinforcing bar structure 10B is installed on the foundation 11 of the building and is connected to the foundation 11. In the outer wall reinforcing bar structure 10B, the reinforcing bar structural material 12 is connected to the foundation 11 with the reinforcing bar structural material 12 located on the indoor side and the external heat insulating material 50 located on the outdoor side. In the outer wall reinforcing bar structure 10B, the upper and lower end reinforcing bars 32 and 33 of the main reinforcing bar 15, the first and second lattice reinforcing bars 34, and the reinforcing bar bridge 14 are connected to the foundation reinforcing bar 39 extending upward from the foundation 11. The foundation reinforcing bar 39 and the main reinforcing bar 15 are connected by using a binding wire (not shown). It is sufficient that at least one of the upper and lower end bars 32 and 33 of the main reinforcing bar 15, the first and second lattice bars 34 of the main reinforcing bar 15, and the reinforcing bar bridge 14 is connected to the basic reinforcing bar 11.

In the outer wall reinforcing bar structure 10B, the iron plate base 13 and the outer heat insulating material 50 are connected by a plurality of separators 40 located between the iron plate base 13 and the outer heat insulating material 50 and extending in the front-rear direction. A casting space 42 for placing concrete 41 is defined between the iron plate base 13 and the external heat insulating material 50. The separator 40 is inserted into a sepa insertion hole drilled in a predetermined portion of the iron plate base 13 and the external heat insulating material 50, and connects the iron plate base 13 and the external heat insulating material 50 (reinforcing bar structural material 12 and the external heat insulating material 50). ing. Formwork fastening metal fittings 43, a round pipe 44 (single pipe), and a P cone 45 are installed at both ends of the separator 40. The round pipe 44 is located between the formwork binding metal fitting 43 and the iron plate base 13, and is located between the formwork binding metal fitting 43 and the external heat insulating material 50, and is located on the iron plate base by the washer 46 of the formwork binding metal fitting 43. It is installed in 13 and the external heat insulating material 50.

In the outer wall reinforcing bar structure 10B, the steel plate base 13 and the outer heat insulating material 50 facing each other form a formwork, and the reinforcing bar bridge 14 and the main reinforcing bar 15 form a reinforcing bar. An L-shaped angle member 47 is fixed to the top of the outer wall reinforcing bar structure 10B by a fixing means, and a plurality of ceiling reinforcing bar structural members 12 arranged in the horizontal direction via the angle member 47 are installed. The ceiling reinforcing bar structural material 12 is the same as that described in the outer wall reinforcing bar structure 10A.

In the outer wall reinforcing bar structure 10B, as shown in FIG. 12, concrete 41 is placed in the placing space 42 between the iron plate base 13 and the outer heat insulating material 50. When the concrete 41 is placed in the casting space 42, the reinforcing bar bridge 14 and the main reinforcing bars 15 (upper end reinforcing bars 32, lower end reinforcing bars 33, first and second lattice bars 34) are buried in the concrete 41. In the ceiling reinforcing bar structural material 12, concrete 41 is cast on the inner surface of the iron plate base 13 with a predetermined covering size. When the concrete 41 is cast on the inner surface of the iron plate base 13, the reinforcing bar bridge 14 and the main reinforcing bars 15 (upper end reinforcing bars 32, lower end reinforcing bars 33, first and second lattice bars 34) are buried in the concrete 41.

Concrete 41 is placed in the casting space 42 and the ceiling reinforcing bar structural material 12, and after the curing period of the concrete 41 has elapsed and the concrete 41 has hardened, the iron plate base is bent so as to bend the leg front portion 28 of the leg rod 26. A force is applied to the leg rear portion 27 of the leg rod 26 that is exposed (extended) rearward from the outer surface 20 of the 13 to divide the leg front portion 28 of the leg rod 26 into two. The procedure for applying force to the rear leg portion 27 is the same as that for the outer wall reinforcing bar structure 10A.

When a force is applied to the rear leg 27 so as to bend the rear leg 27 of the leg rod 26, the narrowed portion 30 formed in the front leg 28 of the leg rod 26 is broken, and the front leg 28 is separated at the narrowed portion 30. The front leg 28 is divided into a substantially upper half and a substantially lower half connecting the rear leg 27 (separated into a substantially upper half and a substantially lower half connecting the rear leg 27) (see FIG. 7). Since the concrete 41 is not cast inside the P cone 16, the narrowed portion 30 can be easily folded, and the leg front portion 28 of the leg rod 26 can be easily folded at the narrowed portion 30 located inside the P cone 16. It can be easily divided into two. Further, there is no concrete 41 inside the P cone 16, and when the leg front portion 28 of the leg rod 26 is divided into two in the narrowed portion 30, the concrete 41 is not damaged in the leg front portion 28 of the leg rod 26. , No concrete repair is required around the leg rod 26.

After folding the narrowed portion 30 and dividing the front leg portion 28 into two parts, the substantially lower half (including the nut 31) of the front leg portion 28 to which the rear portion 27 of the leg rear portion 27 of the two divided front leg portions 28 is connected and the iron plate base 13 are attached. The lower half of the leg front portion 28 to which the leg rear portion 27 is connected and the reinforcing plate base 13 are removed from the reinforcing bar structural material 12 and the ceiling reinforcing bar structural material 12, and the P cone 16 is removed from the reinforcing bar structural material 12 and the ceiling reinforcing bar structure. Removed from material 12 (see FIG. 8). A mortar (not shown) is sprayed on the outer surface of the external heat insulating material 50 that is exposed to the outdoor side.

When the substantially lower half of the leg front portion 28 to which the leg rear portion 27 is connected and the iron plate base 13 are removed from the reinforcing bar structural material 12 and the ceiling reinforcing bar structural material 12, the concrete surface of the hardened concrete 41 is exposed on the inner wall surface and the outer wall surface. Along with the completion of the reinforced concrete outer wall 48b with a concrete base finish, the reinforced concrete slab 49 with an exposed concrete base finish in which the concrete surface of the hardened concrete 41 is exposed to the ceiling surface is completed. The concrete 41 hardened in the casting space 42 and the ceiling reinforcing bar structural material 12 is integrated with the reinforcing bar bridge 14 and the main reinforcing bars 15 (upper end reinforcing bars 32, lower end reinforcing bars 33, first and second lattice reinforcing bars 34).

The outer wall reinforcing bar structure 10A is formed of a plurality of reinforcing bar structural materials 12 and an outer heat insulating material 50 arranged outside the reinforcing bar structural materials 12, and is a plate-like base of the outer heat insulating material 50 and the reinforcing bar structural material 12. Since the concrete 41 is placed in the casting space 42 between the concrete 41 and the concrete 41, even if bending tensile force, bending compressive force, and shearing force act on the concrete 41, the reinforcing bar structural material 12 sufficiently resists these external forces. It is possible to make an exposed concrete base-finished reinforced concrete outer wall 48b having a strength that can be used, and to construct a sturdy reinforced concrete outer wall 48b having a high strength. By using the ceiling reinforcing bar structural material 12, it is possible to construct the reinforced concrete slab 49 having an exposed concrete base finish.

Since the reinforced concrete outer wall 48b made from the reinforced concrete outer wall 10A has high strength, it can sufficiently withstand the violent shaking caused by the earthquake and the water pressure of the tsunami, and can prevent the building from collapsing due to the earthquake. It is possible to construct a reinforced concrete outer wall 48b with an exposed concrete base finish that can prevent the building from being washed away by the tsunami. Further, since the concrete 41 cast in the casting space 42 between the external heat insulating material 50 and the plate-shaped base 13 has excellent sound insulation and excellent fire resistance, noise around the building is blocked. It is possible to construct a reinforced concrete outer wall 48b with an exposed concrete base finish that is resistant to fire.

In the outer wall reinforcing bar structure 10A, the reinforcing bar bridge 14 is attached to the iron plate base 13 by screwing the nut 31 to the leg rear portion 27 of the leg rod 26, and the force is applied to the leg rear portion 27 so as to bend the leg front portion 28. In addition, by dividing the front leg portion 28 in the narrowed portion 30, the substantially lower half of the front leg portion 28 to which the rear portion 27 of the leg of the reinforcing bar structural material 12 is connected and the iron plate base 13 can be removed. It is possible to easily construct the reinforced concrete outer wall 48b having an exposed concrete base finish in which the concrete surface of the concrete 41 cast in the setting space 42 is exposed.

In the outer wall reinforcing bar structure 10A, the main reinforcing bar 15 and the reinforcing bar bridge 14 serve as the reinforcing bars, and the steel plate base 13 and the outer heat insulating material 50 serve as the formwork. Therefore, the reinforcing bar arrangement work, the formwork assembly work, and the formwork removal work. It is possible to construct a reinforced concrete outer wall 48b with an exposed concrete base finish in a short construction period without the need for work, and it is equipped with reinforcing bar arrangement technology without the need for reinforcement reinforcement technology or formwork assembly technology. Workers other than reinforced concrete and formwork equipped with formwork assembly technology can also construct the reinforced concrete outer wall 48b with an exposed concrete base finish.
