[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a composite floor panel in which a steel panel frame used as a floor material of a building such as a residential condominium or an office building is combined with a wooden floor material.

[0002]

[Prior art]

 Conventionally, the floor of a building is constructed by attaching joists and joists to the beams passed between the frames, and attaching the flooring to the top of the joists. Is also usually inserted. Since these beams, joists, joists, braces, etc. will be installed by on-site construction, the construction period will be long and the number of man-hours will be increased, resulting in an increase in cost.

Further, a prefabricated composite floor panel composed of a metal panel frame and a floor surface material is also used. As an example, the floor panel described in Japanese Patent Laid-Open No. 5-302374 will be described with reference to FIG. This figure is a sectional view of the floor panel. 1 is a panel frame, 3 is a floor material, 4 is a base material, and 5 is a heat insulating material. In this floor panel, a solid base material 4 having a high heat insulating property, such as wood, is attached to one side of a panel frame 1 formed of a metal channel material, and the floor surface material 3 is fixed on the base material 4, and the back surface of the floor surface material 3 is fixed. The heat insulating material 5 is fitted into the structure.

Similarly, FIG. 12 shows a floor panel described in JP-A-5-311803. The same symbols as those in Fig. 10 are used. This floor panel was taller than the rising portion 1d provided on the outer peripheral portion of the panel frame 1 because the floor panel that had been used up until then tended to cause dew condensation on the peripheral edge of the floor surface material and impaired habitability and aesthetics. By using the wooden base material 4 and attaching the floor surface material 3 to the upper surface of the base material, the contact between the panel frame 1 and the floor surface material 3 was eliminated and heat insulation was performed to try to eliminate defects such as dew condensation and discoloration. It is a thing.

As described above, the composite floor panel also has the drawbacks of being thick and heavy.

[0006]

[Problems to be solved by the device]

 An object of the present invention is to solve the problems of the conventional floor panel and to realize a composite floor panel which is lightweight, has high strength, and has excellent performances such as heat insulation and soundproofing.

【Example】

 Embodiment 1 A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a sectional view of a composite floor panel of this embodiment, FIG. 2 is a bottom view seen from below, 1 is a panel frame, 1a is a vertical frame member thereof, 1b is a horizontal frame member, 3 is a floor member, Reference numeral 2 is a joining means for joining the panel frame 1 and the floor material 3.

As shown in FIG. 2, this composite floor panel has a joining means 2 such as a screw, a nail, an adhesive, etc., on the upper surface of a panel frame 1 in which a vertical frame member 1a and a horizontal frame member 1b are assembled in a grid pattern. The floor surface material 3 is joined by. The vertical frame member 1a is a C-shaped steel (lip groove steel) formed by bending a thin steel plate with a plate thickness of 0.8 to 1.2 mm into a C shape, and the horizontal frame member 1b is a thin steel plate that is also bent into a U shape. The so-called lightweight channel steel and the floor material 3 are wooden floor materials.

The plate thickness of 0.8 to 1.2 mm is thinner than the conventional light weight channel steel that is commercially available, but for this reason, it is easy to process it by cutting the flange and expanding it to the same plane as described below. In addition, there is an advantage that it is not necessary to process the prepared hole when using a joining means such as a screw. In addition, the floor panel is usually used with the vertical frame extending in the beam-to-beam direction, and the vertical frame member 1a mainly bears the load. Therefore, the floor panel has a cross-section with a slightly greater strength than the horizontal frame member 1b.

3 and 4 are partially enlarged views of FIG. 2 showing an intersecting portion of the panel frame 1, and FIGS. 5 and 6 are perspective views showing the structure of the intersecting portion. 1c is formed on the horizontal frame member 1b. It is a junction. When the intersection is inside the panel frame 1, the horizontal frame member 1b and the joint 1c are T-shaped as shown in FIG. 3, and when the intersection is on the outer periphery of the panel frame 1, these are shown in FIG. Needless to say, it is L-shaped.

At the intersection of the horizontal frame member 1b and the vertical frame member 1a, as shown in FIG. 5, the web and the lower flange are cut by the width of the vertical frame member 1a and are flush with the upper flange. The joint portion 1c is formed by unfolding until it overlaps with the upper flange of the vertical frame member 1a. Assuming that the flange length of the horizontal frame member 1b is a and the height of the web is b, the protruding length of the joint portion 1c is approximately (a + b). As shown in FIG. 6, the vertical frame member 1a is fitted to the cut portion of the horizontal frame member 1b, the joint portion 1c is overlaid on the upper flange of the vertical frame member 1a, and joined by a joining means such as a screw to form a grid pattern. The panel frame 1 is formed.

In the space inside the panel frame 1 surrounded by the grid-like panel frame 1 and the floor surface material 3, a heat insulating material, a sound insulating material, a sound insulating material, etc. (Referred to as a material). As the heat insulating material, foamed resin such as hard urethane foam and styrene foam, and board-shaped or mat-shaped material such as rock wool and glass wool are preferable.

Alternatively, for the same purpose, a steel or wooden plate material may be attached to the lower surface of the panel frame 1, that is, the surface opposite to the floor surface material 3. Second Embodiment A second embodiment of the present invention will be described with reference to FIGS. FIG. 7 is a cross-sectional view of the composite floor panel of this embodiment, FIG. 8 is a bottom view seen from the bottom, the same reference numerals are used for the same parts as before, and 6 is a vertical frame member 1a of the panel frame 1. And a horizontal metal frame 1b.

As shown in FIG. 8, this composite floor panel also has a joining means 2 such as a screw, a nail or an adhesive on the upper surface of the panel frame 1 in which the vertical frame member 1a and the horizontal frame member 1b are assembled in a grid pattern. The floor surface material 3 is joined by. The vertical frame member 1a is a C-shaped steel formed by bending a thin steel plate into a C shape, the horizontal frame member 1b is a so-called lightweight channel steel formed by bending a thin steel plate into a U shape, and the floor material 3 is a wooden floor. It is a material.

FIG. 9 is a partially enlarged view of FIG. 8 showing the intersection of the panel frame 1. The horizontal frame member 1b or the vertical frame member 1a is cut as appropriate to form a grid-like panel frame 1, and the intersection is L-shaped. A letter-shaped, T-shaped, or a cross-shaped joining metal 6 as shown in FIG. 9 is applied and joined by screws or the like.
