Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a heat insulating panel used for walls of construction / building, etc., doors, and other suitable places. The present invention relates to a heat-insulating panel which is a metal plate and includes a necessary heat-insulating material therein.

(Prior Art) Conventionally, as in Japanese Utility Model Laid-Open No. 61-20732, a male type connecting portion formed of an insertion edge protruding outward from a lower end edge of one side wall having a rectangular or rectangular decorative surface and having a concave cross section is provided. A surface material having an insertion groove on the other side wall parallel to the side wall and a female connecting portion having a protruding lower end extending the lower edge of the insertion groove outward, the decorative surface, and two side walls. From a synthetic resin foam provided with a concave portion surrounded by and a bulging portion projecting downward by a thickness T from the back surface of the extension portion in the entire region including the extension portion other than the range of Δl near the insertion edge. In a building panel in which the core material and an exposed surface in the longitudinal direction of the core material are covered with a back surface material, a non-combustible base material having a thickness smaller than the thickness T of the bulging portion is disposed on at least the back surface of the extension portion, The end of the bulging portion under the extension portion is formed by interposing the synthetic resin foam between the non-combustible base material and the back surface material. Architectural panels made are known.

Further, as in Japanese Patent Laid-Open No. 1-94151, a horizontally elongated metal plate, a ceramic plate, or a synthetic resin plate formed by extrusion is used as a surface material, and one end of the surface material has a male connecting portion and the other end edge. Is provided with a female connecting portion, and further, an inclined decorative surface inclined from the male connecting portion toward the female connecting portion is formed to form a gutter-shaped cross section, and the back surface of the surface material is integrally filled with a core material. Then, in the siding board in which the back surface of the core material is covered with a sheet-like back surface material, the shape of the male connecting portion is formed by inserting an insertion edge protruding outward from one end edge of the inclined decorative surface and the insertion edge. An engaging portion having an upper edge and a substantially U-shaped cross section, an extending portion extending outward of a lower edge of the engaging portion, and a gutter-like portion of the inclined decorative surface provided on the engaging portion. Formed with a projecting piece projecting in the same direction, and the shape of the female connecting portion is bent inward at the other side edge of the inclined decorative surface. U and the wall, the lower end of the side wall inwardly
A siding board formed from a fitting groove bent in a letter shape is also known.

(Problems to be solved by the invention) However, in the above-mentioned conventional technique, in the former case, the nonflammable base material provided on the back surface of the extension portion of the building panel becomes the weakest point portion of the building panel. The purpose is to enhance the fire resistance and heat resistance of the male and female joints, and when attaching the building panel to studs, furring strips or other base materials, the base material is applied from the decorative side. There is a problem in that the decorative surface is damaged by the fastener because it is fixed to the panel with appropriate fasteners (bolts, screws, nails and other suitable joint members, etc.). There is a problem that there is a risk that it will penetrate into the inside of the panel and corrode the panel from the inside, and the panel itself is
There is a problem that the fastener will appear on the decorative surface of the panel unless the male and female type connecting structure is used, and the aesthetics of the wall surface etc. will be impaired, and it can not be used for panels other than the male and female type connecting structure. There was a problem.

In the latter case as well, when attaching the siding board to the base material, etc., as in the former case, the siding board is fixed to the base material with a proper fastener (bolt, screw, nail or other suitable joint member) rather than the decorative surface side. Therefore, unless the connecting portion of the siding board is a male-female connecting structure, the fastening tool appears on the decorative surface of the siding board, which spoils the aesthetics of the wall surface and the like, and makes it possible to connect the siding board to other male-female connecting structures. It had the same problem as the former case that it could not be used for panels.

(Means for Solving the Problems) The present invention is intended to solve the above problems, and encloses a required heat insulating material between a decorative surface side metal plate and a back surface side metal plate made of the same material, and the back surface side. In a heat-insulating panel in which both side edges of the metal plate are screwed to a panel mounting base material, both side edges of the decorative surface side metal plate are bent ends in a substantially U-shaped section, and both side edges of the back surface side metal plate are formed. Cross section L
No bent end, and further, an inward bent edge of the metal plate having a substantially U-shaped cross section, and an outer horizontal bent edge of the bent end of the metal plate having a substantially L-shaped cross section on the inner surface. And the screw receiving plate is integrally formed on the inner surface of the outward horizontal bent end edge in a superposed state, and the outward horizontal bent end edge and the screw receive plate are fixed to the panel mounting base material. It is characterized in that it is attached integrally at.

(Embodiment) FIGS. 1 to 5 show an embodiment of the present invention, in which A is a heat insulating panel body, 1 is a decorative surface side metal plate in the heat insulating panel body A , for example, a thickness of about 0.2- It is made of coated hot-dip galvanized steel sheet of about 0.5 m / m, and both side edges thereof are formed into bent ends 1a, 1a having a substantially U-shaped cross section. Reference numerals 1b and 1b are inwardly bent edges of the bent ends 1a and 1a. 2 is a back side metal plate, and is made of a steel plate of the same material as the decorative surface side metal plate 1,
Both side edges thereof are formed at bent ends 2a, 2a having a substantially L-shaped cross section. Reference numerals 2b and 2b are outward horizontal bent edges of the bent ends 2a and 2a.

3 is a heat insulating material enclosed between the both metal plates 1 and 2,
For example, rigid foamed polyurethane, flame-retardant polyisocyanurate foam, novolac type foam, and other fibrous and inorganic aggregates are used.

Outer horizontal bent edges 2b, 2b of the back side metal plate 2 among the metal plates 1, 2 are inward bent edges 1b, 1b of the decorative surface side metal plate 1 as shown in FIG. A screw receiving plate 4 made of metal or another suitable hard plate is integrally formed on the inner surface of the back side metal plate 2 on the inner surface of the outward horizontal bent edges 2b, 2b.

In this case, the outward horizontal bent edges 2b, 2b of the edge of the back side metal plate 2 of the heat insulating panel main body A are brought into contact with the substantially U-shaped bent portion 5a of the panel mounting base material 5 in this state. By integrally fixing with the fastener 6, the decorative surface side metal plate 1 can be easily attached flush with the panel mounting base material 5, and the panel mounting base material 5 has a substantially U-shaped cross section. By appropriately interposing a packing material (not shown) in the space of the curved portion 5a, the reinforcement and watertightness of the mounting portion can be further improved.

(Effect) As described above, according to the present invention, a required heat insulating material is enclosed between the decorative surface side metal plate and the back surface side metal plate made of the same material, and both side edges of the back surface side metal plate are attached to the panel. In a heat insulating panel which is screwed to a base material, both side edges of the decorative surface side metal plate are formed as U-shaped bent ends in cross section, and both side edges of the rear surface side metal plate are substantially L-shaped bent end in section. In addition, on the inner surface of the inwardly bent edge of the bent end of the metal plate on the decorative surface side, the cross section of the metal plate on the rear surface side is substantially L.
The outward horizontal bent edge of the letter-shaped bent end is overlapped, and a screw receiving plate is integrally formed on the inner surface of the outward horizontal bent end edge in a superposed state, and the outward horizontal bent edge and the screw are also formed. Since the backing plate is integrally attached to the panel mounting base material by fastening, since the tip of the fastening tool does not appear on the decorative surface of the heat insulating panel at the time of attaching the heat insulating panel,
There is no fear of impairing the aesthetics of the wall surface, and since the fastening part is located inside the building, there is no fear that rainwater will enter the inside of the heat insulation panel from the fastening part, and The screw receiving plate serves as a reinforcing structure for the edge of the heat insulating panel to reinforce the edge of the heat insulating panel, and also uses the concave space on the back side of the outward horizontal bent edge of the back side metal plate edge. Since the heat insulating panel is attached to the panel mounting base material, various effects can be obtained such that the decorative surface can be attached flush without damaging the heat insulating panel.
