Description of the Related Art Conventionally, a synthetic slab method using a precast concrete plate (PC plate) as a half slab has been known in order to save labor in formwork and reinforcing bar work. The construction method is a method in which a PC plate that also serves as a formwork is erected on a beam, and in-situ concrete is placed on the upper surface of the beam to form a slab integrated with the PC plate after hardening, and half slabs of various shapes are used. ing.

ボイドスラブを形成している（図５B）。In a synthetic slab using this half slab, the weight of the slab is reduced in order to reduce the load due to its own weight, and as an example thereof, a void slab having a void inside the slab is known. This conventional example is shown in FIGS. In the example of FIG. 4, a void form made of corrugated paper, wire mesh, styrofoam, etc. is provided on the upper surface of the PC plate 11 (FIG. 4A), and concrete 21 is cast around the interior so that the form is embedded. Form a slab with voids 15 in it (FIG. 4B). In addition, in the example of FIG. 5, when the PC plate is formed of normal concrete, the rib 30 is integrally formed on the upper surface in advance (see FIG.
A) A void slab having a space between the ribs is formed by placing a lid between the ribs 30 and pouring cast-in-place concrete (FIG. 5B).

るものであってＰＣ版の強度に寄与するものではない。Such a conventional void slab has the following problems. That is, in the case of using the void form shown in FIG. 4, since the form material such as corrugated board has high water absorption, it is not suitable for construction in rainy weather, it is also weak against direct sunlight, and corrugated board and styrofoam are easy to burn. In the vicinity of these forms, bar arrangement work using welding burners etc. is restricted. In addition, since its strength is low, it may be deformed when pouring in-place concrete, and it is also weak against chemicals. The one using a wire mesh or the like for the void form does not have such a problem, but the cost is high. Furthermore, these void forms form an internal space and do not contribute to the strength of the PC plate.

It takes time and effort. That is, the PC plate with ribs is
For the convenience of pouring concrete, it is necessary to use a mold in which the rib portion is formed on the lower side, and after demolding, this must be reversed and used. Since large slabs have a considerable weight, this work is a heavy burden.

There is. The rib portion 13 is made of lightweight concrete, and is integrally connected to the base PC plate by a reinforcing bar embedded inside the rib portion 13. That is, the reinforcing bars 12 are vertically and horizontally embedded in the thin-walled PC plate 11 at a predetermined interval, and the reinforcing bars 14 are also provided inside the ribs. The rib 13 extends to the lower side of the base plate 13 and is joined to the reinforcing bar 12 of the PC plate, whereby the rib portion 13 is integrally fixed to the PC plate of the base plate. The bar arrangement 14 of the rib portion 13 and the PC version bar arrangement 12 are joined by means such as welding. Further, the half slab of the present invention can be further spanned by applying prestress.

ある。Here, the rib portion 13 is for making the plate thickness of the slab seemingly large. Therefore, the shape of the outer cross section of the rib is not particularly limited, and it can be formed in any shape. . For example, as shown in the figure,
A, B, C), semi-circular shape (Fig. 1D), and inverted L shape (Fig. 1)
E) or T shape (Fig. 1F) can be formed. Especially,
The inverted L-shape (Fig. 1E) and T-shape (Fig. 1F) are advantageous for integration with cast-in-place concrete, weight reduction, and longer span.

示省略）。Further, the rib portion 13 has rib portions arranged substantially at right angles to the direction of the bending load applied to the slab, and if the rib portion and the PC plate of the base are integrally joined at the joint portion, Since the rigidity corresponding to the height of the rib portion 13 is obtained, it is not necessary that the entire lower surface of the rib portion 13 be joined to the PC plate. Therefore, as shown in FIGS. 1 (B), (C) and (D), the rib portion 13 may be formed in a hollow shape.
A space may be provided between the substrate 3 and the PC plate 11 of the base (not shown).

部を形成する利点が大きい。The rib portion may be previously formed separately from the PC plate and attached to the PC plate, or may be formed integrally with the PC plate or separately formed on the upper surface of the PC plate. In particular, since the rib portion of the present invention is formed of lightweight concrete, unlike the one in which the PC plate and the rib portion are integrally formed of ordinary concrete, there is a great advantage in forming the rib portion in advance separately from the PC plate.

ブ部を形成する。To attach the preformed rib portion to the PC plate, the rib portion formed of lightweight concrete is used for the PC.
The bar is placed on the upper surface of the plate, and the reinforcing bar extending from the lower portion is joined to the bar inside the PC plate by welding or the like. On the other hand, in order to form the ribs on the upper surface of the PC plate, first, the ribs of the PC plate are assembled together with the ribs of the PC plate, and then the concrete plate is injected to form the PC plate, which is then projected from the surface. Lightweight concrete is cast so as to surround the reinforcement of the rib to form the rib.

とにより、より一層軽量化することができる。As the lightweight concrete used as the material of the rib portion in the present invention, those generally called lightweight concrete such as those using lightweight aggregate and cellular concrete can be used. As the lightweight aggregate, any of artificial, natural and by-product type may be used. By forming the rib portion with lightweight concrete, a half slab having a significantly smaller self-weight can be obtained as compared with the conventional PC slab of the substrate and the conventional rib slab in which the rib portion is formed with normal concrete. Further, by forming the inside of the rib portion to be hollow, it is possible to further reduce the weight.

After that, the cast-in-place concrete 21 is cast on the upper surface of the half slab 10 to fill the space between the rib portions 13 to make the rib portion 13 buried, and the PC plate 1 is cured by hardening the cast-in-place concrete 21.
1. The slab in which the rib portion 13 and the cast-in-place concrete 21 are integrated is formed.

It should be noted that when pouring the cast-in-place concrete, it is advisable to provide upper end bar arrangements 22 as shown in FIG. The strength of the slab is further improved by providing the upper end bar arrangement. The upper end reinforcements 22 are preferably arranged vertically and horizontally on the upper surface of the half slab at a predetermined interval. The reinforcing bar 22 may be provided in advance when the half slab is manufactured in a factory or the like, or may be provided in the field after the half slab is installed between the beams.
