う問題点があった。When used as a simple support material like a conventional precast floor slab, the bending moment acting on the floor slab becomes maximum at the central portion of the floor slab,
The size is 1/8 WL 2 , and the bending moment is 0 at both ends. The W is an evenly distributed load applied to the floor slab, and L is a support span. Since the conventional precast floor slab is made of reinforced concrete to withstand the above bending moment, its thickness is large, and of course, its weight is large, which is not only disadvantageous in transportation and handling, but also this floor slab is Since the beams and pillars to be supported also have to be large, there is a drawback that the construction cost is high. Moreover, in FIG. 4B, the temporary frame becomes complicated, and
Even in (C), there is a problem that it takes time to form the hollow portion. Moreover, the precast floor slab of FIG. 4 (B) was bulky because of the beam-like ribs on the lower surface, and was disadvantageous in transportation and storage as compared with FIG. 4 (C). Further, the conventional precast floor slab has a problem that the corners and the like are often damaged or damaged during transportation, assembly, and disassembly because the concrete surface is exposed at the outer peripheral edge. Furthermore, conventional precast slabs cannot be welded or bolted immediately because the slab is concrete even when the beams and columns are steel frames, and even when the beams and columns are reinforced concrete. In order to connect concrete to each other, another concrete needs to be applied and filled in the joint portion, and there has been a problem that it is not easy to join the members to each other regardless of the beam material or the column material.

る。The object of the present invention is to reduce the thickness and weight of the precast floor slab to save resources, facilitate the transportation and handling of the precast floor slab, and make the beams and pillars of the building slimmer to reduce the construction cost. Also, it is easy to manufacture, prevents the corners from being damaged or damaged during transportation and construction, makes it easy to join the members by welding or bolting, and is easy to assemble and disassemble for dismantling. The purpose is to provide a precast floor slab that does not generate waste, is useful for environmental conservation, enables effective use of resources by reuse, and has the long side direction reinforced with steel.

An example is shown in which the groove 4 is formed on the lower surface to reduce the weight of the plate material, thereby reducing the weight. FIG. 2 (B) shows an example in which the floor finishing material 5 is attached flush to the upper surface by the simultaneous manufacturing method in the factory. By doing so, the number of man-hours for finishing the floor upper surface at the construction site can be improved. Can be reduced. In the concrete material, the reinforcing bars 6 are appropriately arranged in the long side direction and the short side direction. As for the method of arranging the reinforcing bars 6, as shown in FIG. 2 (F), the reinforcing members 6 can be provided in a truss form between the iron aggregates 2 on both sides to have rigidity in the floor surface direction.

の軽量型鋼を使用した場合を例示している。Since the precast floor slab 3 has the steel aggregates 2 arranged on both sides in the long side direction, the length in the long side direction can be increased without increasing the weight. )
As shown in, it can be used as a three-span continuous beam. Moreover, this can reduce the number of plates used and reduce the number of construction steps at the construction site.
In FIG. 2D, it is possible to make the bending moment at the intermediate support position equal to that of the fixed support by increasing the central span L ′ by 1.33 times the double-sided span L in each span.
The bending can be minimized (1/5). However, each span may be equal. When the precast floor slab 3 is used, as shown in (C) and (E) of FIG.
The bolt 7 may be embedded in advance at a position corresponding to the supporting position of 3 spans, and the flange portion of the beam member 8 of the building may be tightly tightened with a nut to be coupled and supported. It should be noted that FIG. 2C illustrates the case where, as the steel aggregate 2, a lightweight steel having a C-shaped cross section is used instead of the grooved steel.

When applied to offices, etc., even when performing underfloor electrical wiring work for the expansion of equipment such as personal computers, the floor slab can be easily removed for construction, and restoration is easy after construction is complete. Further, since the steel aggregates 2 on both sides in the long side direction can provide sufficient strength even if it is thinner than the conventional one, the weight can be reduced and a fixed load applied to a structural material such as a beam or a pillar of a building. Can be reduced, and it is also possible to save structural materials. It can also be used as a wall slab, and in that case, when an opening such as a window is formed, it may be manufactured with a sash frame fitted in the opening. Further, the precast floor slab 3 of the present invention can be used as a connecting beam because the length can be made larger than in the conventional case. The size of each part of the precast floor slab 3 of the present invention is, for example, 65 mm in thickness and 1 in width.
The length is 000 mm and the length is 3000 to 8000 mm. However, it is not limited to this. For example, if a plate having the same plate thickness but a half width is manufactured, the supporting strength can be easily increased due to the presence of the iron aggregates 2 on both sides. Further, the precast floor slab 3 may be joined to a beam or a column by means other than bolting.
