Description

[Detailed Description of the Invention] This invention is primarily concerned with improving a sandwich-like panel that is attached to the steel frame structure of a large outdoor freezer/refrigerator.

The panel used in the above-mentioned outdoor freezer/refrigerator is formed into a rectangular shape with a heat insulating core material such as foamed urethane filled between two plate members, namely, inner and outer surface plates.

However, when the temperature difference between the inside and outside of the refrigerator becomes large, this type of panel becomes warped due to the difference in the materials of the core material and the inner and outer surface plates, or due to the difference in the rate of thermal expansion between the inner and outer surface plates.

Although this is an unavoidable phenomenon, this deflection not only impairs the aesthetic appearance of the structure, but also causes problems such as the caulking of each panel peeling off.

There are also panels with built-in piece-like mounting seats for attaching the panel to the steel frame, but in this type of panel,
For the same reason as mentioned above, sagging occurs between the mounting seats in each panel, and in order to prevent this sagging, it is necessary to reduce the distance between the mounting seats.

However, along with this, extra members such as steel frames and mounting brackets are required, resulting in disadvantages such as a rise in assembly costs and a decrease in assembly efficiency.

This invention is intended to solve the above problems, and the construction panel of this invention will be explained below according to the embodiment shown in the drawings.

The panel of this invention constituting the refrigerator A for outdoor installation shown in the drawing is formed in a rectangular shape like the conventional panel, and its structure is made of foamed polyurethane between two plate members, namely, the inner and outer surface plates 1 and 2. Panel body B filled with hollow core material 3
In the core material 3 of this panel body B,
A through seat 4 made of metal, for example, is buried for reinforcement and for attaching the panel to a structure C such as a steel frame.

The through seats 4 are provided in the longitudinal direction of the panel, crossing each other along the same plane or connected in a rectangular shape, and in FIG. Two through holes 4, 4, which are provided in a diagonal line through or in contact with and fixed to each other, and which are provided parallel to each other in FIG. It consists of

By arranging the through seats 4, 4 as described above, it is possible to prevent not only longitudinal deflection of the panel but also transverse (axial) deflection.

On the other hand, as shown in FIG. 3, the cross-sectional shape of the through seat 4 includes a mounting back seat 4a that is fixed to the inner surface plate 1 and used for attachment to the structure C, and a mounting back seat 4a that extends from the back seat 4a to the outer surface plate 2. A piece 4 extending toward a position close to this outer surface plate 2
b, and a retaining piece 4C extending from the top of this piece 4b along the outer surface plate 2 to form part of the adhesive surface with the core material 3.

The deformation of the cross-sectional shape is shown in FIGS. 4a-d.

A mounting element 5 such as a nut and a through hole (not shown) passing through a bolt 6 which is threadably coupled to the mounting element 5 are attached or provided on the back seat 4a, and the structure C
A bolt 6 passing through a through hole (not shown in the figure) provided in this bracket D, the inner surface plate 1, and a through hole in the back seat 4a is attached to the mounting element 5 through the bracket D attached to the mounting element 5. The panel can then be attached by fitting it into the panel.

As mentioned above, according to this invention, highly rigid through-seats that reduce the temperature difference in the thickness direction of the panel are provided across the longitudinal direction of the panel, and the panel mounting members, that is, the steel frame, This invention has the advantage of being able to significantly reduce the number of parts such as brackets, as well as shortening the assembly time, and also prevents deflection in the longitudinal and axial directions of the panel. Therefore, advantages such as being able to prevent the core material 3 from peeling off when subjected to wind pressure without damaging the appearance of the panel can be obtained.
