2. Description of the Related Art In recent years, there has been an increasing demand for large span slabs having no small beams in dwelling units in order to diversify and upgrade the needs and expand flexibility in the design of apartment houses. In particular, the opening is smaller than the depth (for example, 5.6 × 11 m) such as a dwelling unit in a plate-type standard apartment house, and is closer to a square (for example, 8.0 ×
The need for 8.0 m or 10.0 × 10.0 m) is increasing. On the other hand, there are many floor slab construction methods aimed at labor saving at the site in large span slabs without such small beams. Among them, a composite slab construction method using a semi-PC slab that reinforces the reinforcing steel bar that can be the main beam reinforcement Is most often adopted as a method that is superior in securing required quality (integration and sound insulation) as a floor slab and saving labor. As even better, there is a proposal of a construction method using a full precast slab in order to eliminate cast-in-place concrete in the above construction method. There are floor slabs. When constructing something close to the above square with this floor slab method,
As a matter of course, this full precast version can be designed as a one-way version that can withstand its own weight and the calculated load because the frame is completed by erection between girders without after-site concrete on site Many. In particular one of the ribs in the case of slab light <br/> capacity has been deck or a hollow slab Ribbed
It is a one-way version because it covers all directions.

However, there is no particular problem with such a method of paying in only one direction in the case of an elongated rectangle (λ> 1.5) in which the short side and the long side are clearly different from each other. When the shape is close to a square, (λ ≦ 1.2 ) is not desirable because it is extremely unreasonable in terms of mechanics because it is necessary to reinforce the unnecessary arrangement of reinforcing bars and concrete thickness in one direction. The present invention has been made in view of such problems of the prior art, and the purpose thereof is to provide a one-way version in which the function at the time of laying between girders is only sufficient to withstand its own weight. , by a simple joint operation after laying, a reasonable mechanical function of the two-way version
It is an object of the present invention to provide a full precast slab method that can be used as a slab.

Means for Solving the Problems To achieve the above object, the method according to the present invention comprises embedding beam type reinforcing bars in the long side direction and the short side direction of the plate, and increasing the strength of the plate against its own weight in the long side direction. A full precast floor slab with grid-like ribs is built between girders, and the level is adjusted by a level adjustment jig. After that, the ends of the ribs in the short side direction that abut each other are tightened and joined via bolts. is there.

Since the present invention is configured as described above, it has the following effects. In other words, a floor slab with a maximum span close to a square becomes possible,
Eliminating small beams makes it possible to design buildings (especially multi-family dwellings) that need to accommodate the flexibility of the plan. In addition, it becomes dynamically rational as a two-way version, so that the quantity can be reduced and the cost can be reduced. further,
Since it is a full precast version and does not require post-cast concrete, the advantage of labor saving can be enjoyed compared to the half precast version. In the case of an inverted rib type floor slab, the space under the floor can be effectively used for storage under the floor, piping below the floor, and the like, which is preferable.
