The ceiling slab 11a and the wall 11b made by using the deck plates 10A and 10B to which the glass cloth 14b is fixed have a sound absorption function because the glass cloth 14b exposed on the ceiling surface 33a and the wall surface 33b has a sound absorbing function. Is absorbed by the glass cloth 14b, the sound pressure level of the sound in the room is lowered, and the propagation of the sound in the room to other places is suppressed. Further, since the glass cloth 14b has a heat insulating function, the release of warm air and cold air in the room to the outside is suppressed. Further, since the glass cloth 14b has a high light reflectance, the light emitted from the ceiling light source 38a and the wall light source 38b is reflected by the glass cloth 14b, and the indirect light is diffused indoors.

In the deck plates 10A and 10B, a glass cloth 14b having a predetermined area made by weaving a wallpaper 14a or glass fiber is fixed to the entire lower surface 18 of the metal base 12, and the wallpaper 14a and the glass cloth 14b are attached to the ceiling surface of the ceiling slab 11a.

It can be used as a finishing material or a wall finishing material.

For the deck plates 10A and 10B, the ceiling slab 11a can be constructed without attaching a ceiling finishing material such as a decorative plywood, a plaster board, or an aluminum panel to the hanging bolt, and the wall 11b can be constructed without attaching a wall finishing material. It is possible to omit the ceiling finishing work for installing the ceiling finishing material separately and the wall finishing work for installing the wall finishing material separately, and also save the labor and cost for the ceiling finishing work and the wall finishing work. be able to. Since it is not necessary to attach ceiling finishing materials such as decorative plywood, gypsum board, and aluminum panels to the deck plates 10A and 10B using hanging bolts, compared to the suspended ceiling structure in which ceiling finishing materials are attached using hanging bolts, earthquakes occur. Even if shaking occurs due to such factors, there is no danger of falling, and it is possible to construct a ceiling slab 11a that can prevent the occurrence of a ceiling fall accident.

When the bent portion 28 of the lower end concave portion 27 of the first and second lattice bars 24a and 24b is welded to the convex portion 21 of the metal base 12, welding marks are generated around the convex portion 21 due to the action of heat during welding.

In the deck plate 10C, the bent portions 28 of the lower recesses 27 of the first and second lattice bars 24a and 24b are welded and fixed to the convex portions 21 of the metal base 12, so that the lattice bars 24a and 24b are fixed to the metal base 12. It can be securely fixed, and the fixing between the reinforcing bar truss 13 and the metal base 12 is not inadvertently released, and bending tensile force, bending compressive force, and shearing force are applied to the concrete 37 placed on the deck plate 10C. Even if the concrete 37 acts, the concrete 37 is not damaged by these forces, and the deck plate 10C and the concrete 37 can construct a strong ceiling slab 11a and a wall 11b having sufficient strength.

In the deck plate 10C, the ceiling light source 38a is installed on the ceiling slab 11a on the ceiling slab 11 constructed by using the deck plate 10C, and the wall light source 38b is installed on the wall 11b constructed by using the deck plate 10C. When light is emitted from the ceiling light source 38a or the wall light source 38b, the light is diffusely reflected by the glass cloth 14b having a predetermined light reflectance, and the light from the ceiling light source 38a or the wall light source 38b is diffused. It is possible to construct a ceiling slab 11a or a wall 11b that can increase the feeling of brightness by indirect light from the 33a or the wall surface 33b. In the deck plate 10C, the glass wool 39 having a predetermined area and a predetermined thickness fixed to the entire lower surface 18 of the metal base 12 and the glass cloth 14b having a predetermined area and a predetermined thickness fixed to the entire non-opposing surface 41 of the glass wool 39 have a sound absorbing function. Since the sound absorbing layer 35 and the heat insulating layer 36 are formed with the heat insulating function, the deck plate 10C can be provided with the sound absorbing function and the heat insulating function, and by using the deck plate 10C, the sound absorbing effect and the heat insulating effect are exhibited. The ceiling slab 11a and the wall 11b can be constructed, and the sound insulation and heat retention of the reinforced concrete structure can be improved.
