When a compressive force is applied in the axial direction (vertical direction in Figure 6), the assimilated material has a moderate degree of brittleness. Because of this, the fibers 16 are slightly shifted from each other and deformed. Therefore, this reinforcing member 3 that also serves as a formwork is capable of deforming in the axial direction and does not bear any compressive force in the axial direction. Further, since the reinforcing member 3 which also serves as a formwork is formed by simply solidifying the fibers 16, it is extremely lightweight and easy to handle during transportation.

The external dimensions of the column formed by the structural member A for the small column are the same as those for the second floor and the third floor. This refers to the distance between the joint structures 2, and in the case of the one for the first floor, the length from the lower end of the joint structure 2 to the upper part of the sleeve joint 7. As shown in FIG. 1, a formwork reinforcing member 17 for the reinforcing bar cage connection section is attached to the lower end of this reinforcing member 3 that serves as a formwork for the first floor in a vertically movable manner. There is. The formwork reinforcing member 17 for the connecting portion is also made of high-strength reinforcing fibers 16 in the same way as the formwork reinforcing member 3 described above.

are connected to each other by sleeve joint 7... and erected in their respective predetermined positions. Then, the reinforcing member 17 serving as a formwork for the connecting portion is pushed down to cover this connecting portion (see the connecting portion of the column structural member A on the right side in FIG. 7). Then, structural members A and A for pillars built adjacent to each other
The steel beams 19 of each floor are passed between each of the Shiguchi structures 2.2, and the ends of these steel beams 19 and the ends of the H-shaped M9 of the Shiguchi structure 2 are welded or bolted. etc. (Fig. 7 shows the state in which the second floor casing I9 is attached).

Then, concrete is poured while gradually pulling up the tremie pipe, and concrete 20 is poured all over the inside of the reinforcing member 3 that also serves as the formwork and the inside of the steel pipe 8 of the joint structure 2.
Fill it with.

In addition, the steel beam 19 can be easily and reliably joined to the joint structure 2, and the steel beam 19
and the column main reinforcements 4 are sufficiently firmly connected via the shiiguchi structure 2. In addition, by using this column structural member A, the reinforcing member 3 that also serves as a formwork is attached to the reinforcing bar basket L in advance, so on-site construction (assembly and dismantling work) of the formwork can be omitted. In this respect, it can contribute to shortening the construction period. Also, training: -Flute 7

ト２０の断面を小さくすることができる。By using this pillar structural member A, the formwork reinforcing member 3 can reinforce the concrete 20 cast inside and increase its strength. That is, when compressive force and shearing force in the axial direction are applied to the concrete 20, the concrete 20 tries to deform so as to bulge outward, but at this time, the reinforcing member 3 that also serves as a formwork tightens the concrete 20 from the outside, resulting in a so-called compaction. It exerts a finding effect and prevents its deformation. As a result, the compressive strength and shear strength of the concrete 20 can be significantly increased compared to conventional reinforced concrete with the same cross section, or the cross section of the concrete 20 can be made smaller to obtain the same strength. .

This formwork reinforcing member 3 itself does not buckle or yield, and can always and reliably exhibit the confining effect. In addition, since we decided to use hli strong members that also serve as formwork for the connection part of the reinforcing bar cage l, it is possible to omit the formwork work in this part, and the connection part is exactly the same as other parts. strength can be obtained.

等、種々の形態が考えられる。In this structural member B for columns, the reinforcing member 3 that also serves as a formwork in the above-mentioned structural member A for columns is used as a reinforcing member that also serves as a formwork.
A steel pipe 21 having the same shape and dimensions is used. As shown in FIG. 10, this steel pipe 21 has a deformation absorbing portion 22 formed approximately at its longitudinal center. When an axial force is applied to the steel pipe 21, the deformation absorbing portion 22 easily expands and contracts to absorb the deformation of the steel pipe 21, allowing the steel pipe 21 to move freely in the axial direction without resisting the axial force. It allows it to be transformed. Specific configurations of the deformation absorbing portion 22 include, for example, a structure in which the steel pipe 21 is cut at the top and bottom to form a ring-shaped gap and filled with a flexible material such as rubber, or a structure in which the inner or outer surface of the steel tube 2I is A ring-shaped groove is formed and the part is actively used as a weak part to make it easy to buckle, and a plurality of long lengths extending in the circumferential direction are formed in the steel pipe 21 and the part is made to have elasticity in the axial direction. Various forms are possible, such as

塗布しておくことにより形成することができる。Further, an unbonding treatment layer 23 is formed on the inner surface of the steel pipe 21. This unbonding treatment layer 23 is applied to the steel pipe 2
This is to prevent adhesion between the concrete 20 placed inside the concrete 1 and the concrete 20 placed inside the concrete 20, thereby maintaining an unbonded state. This unbonding layer 23 can be formed by, for example, applying paraffin, grease, vaseline, asphalt, etc. to the inner surface of the steel pipe 21 in advance.

A structural member B is formed. Note that a steel pipe 24 for a reinforcing bar cage connection portion is attached to the lower end of the steel pipe 21 for the first floor so as to be movable up and down.

Therefore, even when an axial force is applied to the concrete 20, the steel pipe 21 is not affected by it.
