ている。2. Description of the Related Art A reinforced concrete precast plate (hereinafter referred to as a PC board) is laid on a beam at a construction site, and a finishing mortar or a reinforcing bar is arranged thereon and concrete is poured into the reinforced concrete. The method of construction is widely practiced.

ト、せん断力を負荷させている。The PC board 1 used in this method has a cross section having ribs 3 as shown in FIGS. 1 to 3 and is bridged between adjacent beams, so that a piano wire or a reinforcing bar 4 is arranged in the ribs 3. By doing so, a bending moment and a shear force applied to the floor are applied.

し、Ａは相隣るＰＣ板の接合部を示す。The PC board 1 comprises the ribs 3 and the flat plate portion 2. The flat plate portion 2 has a plate thickness of about 3 cm to 9 cm. The PC plate 1A shown in FIG. 1 is a single T plate (with lower ribs). PC boards 1B and 1C shown in FIGS. 2 and 3 are called double T plates (with a lower surface rib and a lower surface flat finish). In general, the bending rigidity in the length direction is large, but the torsional rigidity is relatively small. 1 to 3, C indicates cast-in-place concrete, and A indicates a joint between adjacent PC boards.

When the flat plates 2 of the adjacent plates 1 and 1 are connected to each other without any step when laying them, as shown in FIGS. 5 and 6, the flat plate 2 is cut out to expose the reinforcing bar 5 inside the flat plate. A method is used in which the notched reinforcing bars 5, 5 of the plate portions 2 of the adjacent plates 1, 1 are connected and fixed by welding 7 or the like via metal fittings 6 or the like.

FIG. 7 is an example of misalignment due to twisting, FIG. 8 is an example of misalignment due to manufacturing error in plate thickness, and FIG. 9 is an example of misalignment due to a combined cause of torsion and manufacturing error.

た時、版相互の目違いは避けられないことが多い。[0007] As described above, since the torsional rigidity of the PC board is small, the step difference between the flat plate portions of the adjacent PC boards is corrected using a large bar or the like on the laid PC boards, and the above-mentioned PC board is immediately used. Although labor is required for on-site work due to a manufacturing error of the PC board such as performing a connection work such as welding, etc., when looking up from below the PC board, it is often inevitable that the plates differ from each other.

することもできる。The present invention has the following excellent effects. (1) Workability is good because work can be performed from the laid PC boards. (2) Since the bolts with the supporting plate can be collected after the floor plate is constructed, there is no residue on the lower surface of the PC plate, and there is no fear of rusting.
In addition, the bolts with support plates can be reused. (3) There is a slit on the lower surface of the PC board, which is about the same as the chamfered joint. However, because the width is small, it is possible to finish paint, cloth, etc. directly on the ceiling with a base treatment such as mortar or putty. You do not need to stick it. Moreover, it can also be set as a direct finish.
