Description

[Detailed Description of the Invention] [Object of the Invention] Industrial Field of Application The present invention relates to a heat insulating panel in which a foamed heat insulating material is filled between inner and outer panels arranged at a predetermined interval. The present invention relates to an improvement in a columnar member that is disposed at the end of an inner and outer surface plate and partially exposed.

Conventional Technology To construct a prefabricated refrigerator or freezer, a plurality of heat-insulating panels are usually combined to form a box-like structure having a top wall, side walls, and bottom wall. As disclosed in the official gazette, for example, a recess or a convex part is formed at the connection end of a one-tatami-sized heat insulation panel with another panel, and the convex part is combined with the concave part. The panels are connected together using locks.

Problems to be Solved by the Invention When forming a box shape by combining heat insulating panels, when configuring the corners of the box, a convex portion or a concave portion is formed only at the end of the panel in the thickness direction. Since it is impossible to construct the panel by itself, one of the panels installed at the corner has a flat end face in the board thickness direction, and a concave groove is formed at the end of the inner surface material, and the end face of the other panel is It is possible to combine the protrusions provided on the sides. and,
This makes it possible to form an insulating box, but the box is usually provided with a door for storing and taking out stored items inside the box, and this door and side walls are made up of To install the door so that it is on the same surface as the panel, a frame is created to surround the door and this frame is attached, but a flat surface is required to install this frame (to form this flat surface, (Traditionally, pillar-shaped wood was used). In particular, if the door is installed at a corner of the box, it will not be possible to install a groove in the corner, so although it is possible to install the door, panels will be required at the top and bottom of the door. At the time, a special connecting member was required, for example, having a cross-sectional shape. For this reason, there is a problem in that the connecting member protrudes from the panel surface, and only this connecting portion cannot be flattened.

In addition, since it is not possible to provide grooves in the corners of the door installation, it is not possible to provide a panel coupling device called a rotary lock, making panel installation laborious and difficult. There was also the problem that the panels could not be firmly fixed together.

Therefore, the present invention provides a heat insulating panel in which columnar members having grooves and flat surfaces are arranged at the corners of a box.

[Structure of the invention]

Means for Solving the Problems The heat insulating panel of the present invention includes an outer material having a bent surface with one flat side in the thickness direction of the panel and a flange portion formed at the end of the bent surface; It has an inner surface that is arranged at a predetermined interval and has a flange portion at the end, a surface that is located inside the folded surface and has a groove that connects the convex portion on one side of the other heat insulation panel, and a flat surface. It is provided with a columnar member disposed so as to expose a flat surface or a groove between the facing flange portions of the inner and outer members, and a foamed heat insulating material filled between the inner and outer members.

A working flat surface (16) and a concave groove (17) are formed (
A columnar member (18) having both of (28) and (28) is disposed at a corner portion of the panel so that it can be combined with a convex portion and a flat portion.

The columnar members (18) are molded from foamed resin such as foamed polystyrene, and the thermal conductivity is almost the same as that of the foamed insulation material (30), so that dew condensation due to cooling inside the box is prevented from forming on the panel corners. I try not to concentrate on the club.

EXAMPLES Examples of the present invention will be described below with reference to FIGS. 1 to 6.

(1) is a prefabricated insulating box constructed by connecting and connecting multiple insulating panels (2) and transparent doors (3), and the insulating panels include a ceiling panel (4), a side wall panel ( 5), a floor panel (6), and especially at the front of the insulating box (1) where the transparent door (3) is installed, the front upper wall panel ( 7) and transparent door (3)
The front lower side wall panel (8) is located at the lower part of the front side wall panel (8). Each panel usually has a fixed shape of a rectangle, and has a pair of inner and outer panels disposed at a predetermined distance, and a foamed heat insulating material (such as foamed polyurethane) filled between the panels. 30), and the peripheral edges of both the inner and outer surfaces are provided with recesses or protrusions that serve as connecting portions for coupling and connecting the panels. These concave portions and convex portions may be formed of a foamed heat insulating material, or a frame material specially formed by extrusion molding of a foamed resin such as foamed vinyl chloride may be provided. A coupling device called a rotary type lock, which is combined with a concave part and arranged in a convex part and a concave part (this is a pair of a hook body with a book and a pin body with a pin), makes it easy to During the work, the panels are firmly connected and fixed together. So, to explain an example, a hook body is placed inside the convex part, a pin body is placed inside the concave part, and by rotating and hooking the hook of the hook body to the pin in the pin body, both are firmly attached. It is held and fixed.

On the other hand, in areas where panels are connected on the same plane, protrusions or recesses are formed on the end faces in the thickness direction of the panels, and in areas where connections are perpendicular, adjacent panels are A convex portion is formed on one end face in the thickness direction and a groove is formed on the other end face on the inner surface material side, and the panels are assembled together by combining the convex portion with the concave portion.

On the other hand, the front upper wall panel (7) and the front lower wall panel (8) located at the front of the box body in which the transparent door (3) is installed are attached to the third
As shown in the figure, when installing the transparent door (3) on the left and right side wall panels that make up the front corners, it is difficult to install the transparent door (3) with the conventional panel configuration because it requires a flat surface. Since all of the attached parts are uniformly flat, it is impossible to assemble with uneven parts. Therefore, in order to be able to assemble the protrusions (7^) (8A) provided at the ends of the front upper wall panel (7) and the front lower wall panel (8), we installed the The side wall panels (9) and (10) located will be explained. However, in this example, only the left side wall panel (9) is taken up. The structure of this side wall panel (9) is substantially the same as that of the panel forming the corner of the box (1) (referred to as a corner forming panel), so the structure of the corner forming panel will be explained first.

Among the four end faces of the panel in the thickness direction, one end face that will be located at the corner of the box (1) when it is completely installed is a flat surface, so it is bent by the thickness of the panel. An outer surface material (13) having a bent surface (11) and a flange portion (12) having a cross-sectional shape formed at the end thereof, and a constant gap (

For this reason, it is necessary to fix the frame (26) as well as the front upper wall panel (7) and the front lower wall panel (8).
It can be combined with the convex part on the end face of the holder, and can also be fixed with a rotary lock. On the other hand, the columnar member (18

〔Effect of the invention〕

As described in detail above, according to the present invention, a columnar member having a flat surface and a surface in which a groove is formed is placed on the inside of a bent surface that makes one end surface in the thickness direction of the panel flat. Since the heat insulating panel is arranged so that the flat surface or groove is exposed between the facing flanges of the outer material, the flat surface and the groove are exposed between the flanges. By doing so, it is possible not only to combine it with the convex parts of other panels, but also to arrange a transparent door, and it is possible to use any part of the box as a heat insulating panel constituting the corners of the box. In addition, if the columnar members are made of foamed resin, the difference in thermal conductivity from that of the foamed insulation material can be reduced, which prevents dew from concentrating near the corners of the insulation box, especially on transparent doors. The amount of dew buildup on the front of the box body where it is installed can be reduced. Furthermore, since it is possible to combine the concave groove and the convex portion, the panels can be connected and fixed by a rotary lock, and the panel can be fixed securely and firmly.
