Description

  The present invention relates to a heat insulating panel of a reinforcing material embedded type that constitutes, for example, a ceiling, wall, or floor of a building.

  In general, as a type of structural panel constituting a ceiling, wall, floor, or the like of a building, a heat insulating structure in which a heat insulating material is sandwiched between a pair of surface plates is used. Further, as this type of heat insulating panel, a pair of surface plates, a frame member interposed between the side portions of these surface plates, and a foam that is injected and filled into a space formed by both surface plates and the frame member, for example The thing of the heat insulation structure which consists of heat insulating materials, such as a polyurethane, is used.

In order to increase the strength of the heat insulating panel, a reinforcing material having a substrate extending in a direction parallel to the surface of the surface plate and a vertical plate extending in the thickness direction of the surface plate is embedded in the heat insulating material. (See, for example, Patent Document 1).
JP 2003-56117 A (claim, paragraph number 0002, FIG. 3)

  However, when the technique described in Japanese Patent Application Laid-Open No. 2003-56117 is applied to a heat insulating panel filled with a foamable heat insulating core material, when the heat insulating core material is injected and filled between the surface plates in panel manufacture, the liquid flow of the heat insulating core material is reduced. When it is blocked by the reinforcing material and foamed and solidified at a predetermined temperature after injecting and filling the heat insulating core material, there is a difference in density within the panel, resulting in traces on the surface plate, which deteriorates the heat insulation and impairs the appearance. . In addition, since a density difference is generated in the heat insulating core material around the reinforcing material, there is a problem that the biting strength of the reinforcing material into the heat insulating core material is reduced. In addition, when a heat-insulating core material having a high reaction rate is used, there is a problem that the above problem appears remarkably.

  The present invention has been made in view of the above circumstances, and provides a heat insulating panel capable of smoothly filling and foaming a foamable heat insulating core material in panel manufacture and making the density of the heat insulating core material in the panel uniform. The purpose is to do.

  In order to solve the above-described problems, the present invention injects a pair of surface plates, a frame member interposed between the side portions of the surface plates, and a space formed by the both surface plates and the frame member. A heat insulating panel comprising: a heat insulating core material to be filled; and a reinforcing material that is in contact with the inner surface of the one surface plate and has one end embedded in the heat insulating core material. A substrate capable of contacting the inner surface, a vertical plate extending from one side of the substrate in the thickness direction of the heat insulating panel, and a horizontal plate extending substantially parallel to the surface plate from the tip of the vertical plate And the vertical plate and the horizontal plate are provided with a plurality of cut portions (claim 1).

  In the present invention, as long as a plurality of the cut portions are provided on the vertical plate and the horizontal plate, the shape thereof may be arbitrary, but preferably it is not provided at both ends of the vertical plate and the horizontal plate. Item 2). Further, it is preferable to form a mounting screw receiving portion formed by burring and tapping on the substrate.

  Since the reinforcing material for a heat insulating panel according to the present invention is configured as described above, the following effects can be obtained.

(1) According to the invention described in claim 1, by providing a plurality of cut portions in the vertical plate and the horizontal plate of the reinforcing material, the insulating core material is smoothly filled and foamed between the surface plates in panel manufacture. Since the foam material density in the panel can be made uniform, it is possible to secure the biting strength of the reinforcing plate into the heat insulating core material, to improve the heat insulating property of the panel, and to improve the panel aesthetics. Improvements can be made.

(2) According to the invention described in claim 2, the vertical plate and the horizontal plate are embedded in the heat insulating core material broadly by not providing the cut portions of the reinforcing material at both ends of the vertical plate and the horizontal plate. Therefore, in addition to the above (1), the biting strength of the reinforcing plate into the heat insulating core can be further improved.
