The above-mentioned conventional PC
In the method of joining floorboards, a hoop-shaped joining portion of the reinforcing bar of one PC floorboard and a hoop-shaped joining portion of the reinforcing bar of the other PC floorboard are joined via the cast concrete. However, the joint is insufficient compared with the method of directly joining the joining portions of the reinforcing bars, and therefore, the upper and lower sides of the hoop-shaped joining portion of the reinforcing bars located in the concrete casting space. Or it is necessary to arrange a large number of reinforcing bars on the upper, inner and lower sides in parallel with the edge of the PC floorboard, and it takes a lot of man-hours to process the joints of the reinforcing bars into a hoop shape, In addition, there is a drawback that a lot of labor is required to insert a plurality of long reinforcing bars into a space surrounded by a hoop-shaped joining portion formed by overlapping portions in a side view. In the above-mentioned conventional method of joining PC floorboards, a rectangular hoop-shaped joining portion of a reinforcing bar of one PC floorboard and a rectangular hoop-shaped joining portion of a reinforcing bar of the other PC floorboard are brought into contact with these portions. It is joined through a long bearing plate and cast concrete, and the joining is insufficient compared with the case where the joining parts of the reinforcing bars are directly joined together. It is necessary to arrange a large number of reinforcing bars parallel to the end face of the PC floor plate on the upper and lower sides of the rectangular hoop-shaped joining portion of the reinforcing bar located in the space for use. It takes a lot of man-hours to process it, and furthermore, two long supporting plates are inserted into a space surrounded by a rectangular hoop-shaped joining part formed by overlapping parts in a side view. Has the disadvantage of requiring a lot of labor The conventional method of joining PC floorboards described above involves fitting two steel sleeves at their longitudinal intervals at the connecting portions of a pair of rebars which are adjacent and parallel to each other and lie on the same plane. The wedge is pressed into the central hole of each steel sleeve fitted to the connecting portion of the pair of reinforcing bars, and the connecting portion of the pair of reinforcing bars is connected. It is necessary to increase the width of the concrete casting space for accommodating the long reinforcing bar connection parts, which is difficult to apply to beams with narrow flanges. There is a disadvantage in that a large number of man-hours are required to incline at a constant angle with respect to a straight line connecting the edges of the sides. The problem to be solved by the present invention is to provide a method of fixing full PC floorboards to various beams of a building frame and a method of fixing full PC floorboards to each other, which has no such drawbacks of the prior art, in other words, Even if the connecting portion of the reinforcing bar embedded in the full PC floorboard projecting from the end face of the floorboard is connected by a connection method by press-fitting a steel sleeve and a wedge, the gap between the adjacent full PC floorboards is reduced. Good workability of fixing work of full PC floor panel to various beams of building frame, arranging deck plate on beam of building frame and constructing reinforced concrete floor panel on deck plate To provide a method of fixing full PC floor plates to various beams of a building frame and a method of fixing full PC floor plates to each other, which can provide a floor plate structure having the same structural characteristics as a plate floor plate structure.

The shape in plan view of the shear cotter formed on the upper side of the full PCRC beam 3 is not limited to the square shown in FIGS. 20 and 21, but may be any shape such as a rectangle, a circle, and an ellipse. However, the depth of the shear cotter is suitably about 10 mm to 30 mm, and if it is such a depth, it usually interferes with the reinforcement arrangement of the full PCRC beam 3 (that is, the main reinforcement 3a and the rib 3b). This is convenient for manufacturing the full PCRC beam 3. Instead of the shear cotter, it is also possible to roughen the upper surface of the precast RC beam on which the cast-in-place concrete is cast to transmit the shear force at the joint.
