Thus, when the construction of the concrete floor is completed after the curing period of the concrete, the construction of the ceiling on the lower floor, the electric wiring, etc. are completed, and the construction period is significantly shortened.

In addition, the formwork deck plate with ceiling finishing material of the present invention, which can perform both concrete floor construction and ceiling construction at the same time, has a small space between the concrete placing steel sheet and the finished ceiling steel sheet, so that the space between the concrete floor and the ceiling is small. Remarkably less, so even if the height of each floor is low, living space can be taken high.

[Embodiment] An embodiment of the formwork deck plate with ceiling finishing material of the present invention will be described with reference to FIGS. 1 and 2. Reference numeral 10 is a flat zinc steel plate, a color steel plate, or a thin plate such as black leather for concrete pouring steel plate. At the left and right sides in the longitudinal direction of the surface, embossments 11 that are long in the width direction are formed by press molding at regular intervals. On the back surface of the concrete pouring steel plate 10, an upper projecting portion 13 for forming one dovetail groove 12 is provided in the center of the lower surface in the longitudinal direction, and is inclined inward at the same height as the upper projecting portion 13 so that both left and right sides are inclined. The wall 14 is provided, and the top and bottom grooves 17 on the left and right sides of the decorative steel plate 16 such as a color steel plate or a vinyl chloride steel plate on which a pattern such as wood grain is printed on the lower surface of the flat trapezoid provided with the flanges 15 on the outer ends of the left and right side walls 14 The finished ceiling steel plate 19 formed by adhering the foam material 18 is polymerized to form the flange 15 and the upper protruding portion 13
Is spot-welded on the upper surface of the concrete pouring steel plate 10, and a space 20 is formed between the foam material 18 and the concrete pouring steel plate 10.

Next, another embodiment will be described with reference to FIG. 3. In this embodiment, the concrete pouring steel plate 10 is replaced with a concrete pouring steel plate 10 'having a rectangular corrugated width direction. The other points are exactly the same as in the above embodiment.

The formwork deck plates 21 and 21 'with ceiling finishing materials of the respective embodiments configured as described above are provided with beams 22 as shown in FIGS.
By arranging and mounting on top, the steel plates for concrete placing 10 and 10 'on the upper surface will be set as the formwork of the concrete floor, and at the same time the finishing ceiling steel plate 19 on the lower surface will be set as the ceiling plate. Become. Then, the front and rear ends of the formwork deck plates 21 and 21 'with ceiling finishing materials are closed, and the reinforcing bars 23 are arranged above the steel plates 10 and 10' for concrete placing, and at the same time the concrete 24 is placed.
