Abstract

(57) [Summary] [Purpose] To provide floor panels with high heat insulation performance. [Structure] A face plate 2 is placed on top of opposing metal frame members 1. A heat insulating material 3 is attached to the back surface of the face plate 2. The support projecting piece 4 projecting from the upper portion of the metal frame member 1 is brought into line contact with the lower surface of the face plate 2 to support the face plate 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floor panel having high heat insulation performance.

[0002]

[Prior art]

 Conventionally, there is a floor panel as shown in FIG. This floor panel is formed by mounting a face plate 2 on the upper surface of a metal frame member 1 having a U-shaped cross section and providing a heat insulating member 3 on the back surface side of the face plate 2 for ensuring heat insulation. . The face plate 2 placed on the metal frame member 1 is supported so as to be placed on the placing piece a formed by bending the upper portion of the metal frame member 1 into an L shape. .

[0003]

[Problems to be solved by the device]

 However, in the conventional example as described above, the metal frame member 1 and the face plate 2 are directly in surface contact with each other by the mounting piece a. Heat is directly generated toward the surface plate 1, and also directly from the metal frame material 1 toward the face plate 2. This heat transfer causes a variation in the surface temperature of the face plate 2, which causes the floor panel There was a problem that the heat insulation was low.

The present invention is intended to solve the above problems, and an object thereof is to provide a floor panel having high heat insulation performance.

[0005]

[Means for Solving the Problems]

 In the present invention, in order to achieve the above-mentioned object, a face plate 2 is placed on an upper portion of a metal frame member 1 facing each other, and a heat insulating material 3 is attached to a back side of the face plate 2, and an upper portion of the metal frame member 1 is attached. The supporting projecting piece 4 which is further projected is brought into line contact with the lower surface of the face plate 2 to support the face plate 2.

[0006]

However, even though the supporting strength is improved by the metal frame member 1, the metal frame member 1 does not allow the supporting projections 4 provided on the upper portion to come into line contact with the lower surface of the face plate 2 to form a surface. Since the plate 2 is supported, heat conduction does not easily occur from the face plate 2 to the metal frame member 1, and heat conduction does not easily occur from the metal frame member 1 to the face plate 2. .

[0007]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. The floor panel A is mainly composed of a metal frame member 1 framed in a rectangular shape, a face plate 2 placed on the metal frame member 1, and a heat insulating member 3 attached to the back side of the face plate 2. Is configured.

As shown in FIG. 1, the metal frame member 1 is formed in a U-shaped cross section, and a supporting projection 4 for supporting the face plate 2 by being in line contact with the lower surface of the face plate 2 is provided on the upper portion. It is provided. The support projection 4 is provided with a receiving member 5 having a U-shaped cross section on the upper portion of the metal frame member 1, and is formed by the protruding pieces 5a at both ends of the receiving member 5. The face plate 2 is supported by abutting against the lower surface and making line contact. The face plate 2 and the metal frame member 1 are connected and fixed by driving a fastener 6 such as a nail from the surface of the face plate 2 toward the receiving member 5 and the metal frame member 1.

The heat insulating material 3 is provided on the entire lower surface of the face plate 2 and on the upper portion of the metal frame material 1 so as to impart a high heat insulating property to the floor panel A. However, even though the supporting strength is improved by the metal frame member 1, the metal frame member 1 is configured such that the supporting projections 4 provided on the upper portion are brought into line contact with the lower surface of the face plate 2 to fix the face plate 2. Since it is supported, heat conduction does not easily occur from the face plate 2 to the metal frame material 1 and heat conduction does not easily occur directly from the metal frame material 1 to the face plate 2. It is possible to obtain the floor panel A having high heat insulation performance without causing temperature variations.

FIG. 2 shows another embodiment, in which the floor panel A is constructed such that the heat insulating material 3 is interposed between the upper and lower face plates 2. In this floor panel A, a metal frame member 1 having a hat-shaped cross section is arranged back to back between the end portions arranged adjacent to each other. The supporting projections 4 provided on the upper part support the face plates 2 by line contact. 7 is a foamed resin such as foamed phenol filled and arranged between the supporting projections 4 of the adjacent metal frame members 1. The foamed resin 7 is used to bond and fix the face plate 2 and the metal frame member 1 to each other. ing.

[Effect of device]

 As described above, the present invention mounts the face plate on the upper part of the facing metal frame material, and additionally installs the heat insulating material on the back surface side of the face plate, and the supporting projections projecting from the upper part of the metal frame material. Since the surface material is supported by making line contact with the lower surface of the face plate, even though the support strength is improved by the metal frame material, the metal frame material does not have the support projections provided on the upper part. Since the face plate is supported by making line contact with the lower surface of the face plate, heat conduction does not easily occur from the face plate to the metal frame material, and heat conduction does not directly occur from the metal frame material to the face plate. The floor panel does not have temperature variations on the face plate, and can be a floor panel with high heat insulation performance.
