スラブと一体化させる。(Prior art) Conventionally, PC beam 1 shown in Fig. 5 has been used as a PC member.
a has been proposed. The PC beam consists of a PC portion 2a, a reinforcing bar cage 3a, and an expanded metal 4a. The PC part 2a is hollow inside and open at the top, and the reinforcing bar cage 3a is buried in the PC part except for the top end, and the metal is placed on the inner surface of the hollow part and fixed with a stiffener (not shown). ing. The manufacturing method of PC beam 1a is
The metal 4a is set inside the reinforcing bar cage 3a and fixed with reinforcement bones, the outer formwork is assembled on the outside of the reinforcing bar cage, the metal is used as the inner formwork, and concrete is poured between the outer formwork and the beam. It is something that forms. PC beam 1
To use method a, install the PC beam, pour slab concrete, and at the same time pour this concrete.
Also installed inside the hollow part of PC beam 1a, reinforcing bar cage 3a

３３を力骨としてこのかごに張設してある。 In FIG. 1, the PC portion 2 of the PC beam 1 has a hollow portion 21 and is open at the top. The reinforcing bar cage 3 is exposed in contact with the inner surface of the hollow part 21, and the upper end is
It protrudes upward from the upper end surface of the PC portion 2. In addition, the reinforcing bar cage 3 has a stirrup 33 wrapped around the upper end reinforcement 32 and the lower end reinforcement 31, and the upper end reinforcement is connected to the PC.
Reinforcement will be arranged during construction of beam 1. In reinforcing bar cage 3
The outer part located within the PC part 2 is covered with a wire mesh 4. This wire mesh is stretched around the reinforcing steel cage 3 using the stirrups 33 of the cage as support bones.
ここでPC梁１の製造について説明する。 Here, manufacturing of the PC beam 1 will be explained.

分も構造体として使用できる。 First, a wire mesh 4 is pasted on the outside of the reinforcing bar cage 3 located inside the PC section 2, using the stirrups 33 as support bones, then an outer form is set with a predetermined cover thickness on the outside of the wire mesh, and finally the wire mesh and Concrete is poured between the outer formwork and the outside formwork. When pouring concrete, the wire mesh 4 functions as an inner formwork, and the mesh part is formed with a rough surface, which improves the adhesion performance with concrete that will be applied later on site, and the PC part can also be used as a structure.

After installing the PC beam 1 and assembling the slab formwork, the upper end reinforcement 32 is placed inside the upper end of the reinforcing bar cage 3, the slab reinforcement is placed, the slab concrete is poured, and the concrete 5 is placed at the same time.
Also install it inside PC beam 1. In this way, the upper end of the reinforcing bar cage 3 of the PC beam 1 is buried and fixed in the slab concrete, and the PC beam and the floor 6 are integrated.

The member is a PC column 11. The configuration of PC pillar 11
It is substantially the same as PC beam 1. 12 is the PC part,
13 is a reinforcing bar cage, and 14 is a wire mesh attached to the outer surface of the reinforcing bar cage. The PC part 12 has a hollow part 121 in the axial direction, and both upper and lower ends of this hollow part are open, and concrete 5 is placed in it when in use.

を一致させてある。 In the example shown in Figure 1, if the wire mesh 4 is stretched directly outside the slurrups 33, the "slowness" of the concrete will be applied to the stirrups, so in order to prevent this, the wire mesh is fixed as shown in Figure 4. The abdominal muscles 34, which are reinforcing bars, may be arranged and the wire mesh 4 may be attached to these abdominal muscles. The other configurations are substantially the same as the example shown in the first figure, so the reference numerals are the same.

として使用できる。(Effects of the Invention) As explained above, according to the present invention, the reinforcing bar cage is exposed in contact with the inner surface of the hollow portion, a wire mesh is stretched in contact with the outside of the reinforcing bar cage, and this wire mesh is attached to the reinforcing bar cage. Since I made it so, I could use my PC like before.
The thickness of the parts does not get too thick and there is no need for bracing, making it possible to reduce the weight of the PC member, making it easier to construct, requiring a smaller lifting machine, and reducing the roughness of the wire mesh parts. This increases the adhesion performance of the PC part to concrete and allows the PC part to be used as a structure.
