Description

[Detailed description of the invention] This invention relates to the improvement of a heat insulating panel with a wavy surface, which is formed by filling a heat insulating core material between a pair of face plates, at least one of which has a wavy shape with concave portions and convex portions. be.

In general, this type of panel has an uneven surface formed on the surface plate, so it is advantageous in terms of strength during use. Since it is necessary to fix the parts, there is a drawback that it requires man-hours and skill, and it is also unhygienic when used in refrigerators, clean rooms, etc.

That is, in the past, as shown in Fig. 1, one side C' of the closing material C having an L-shaped cross section was fixed to the surface of the convex group at the end of the panel a with a fixing device d such as a rivet. , a recess f is formed between the recess e of the corrugated part and the closing material C, and there is a sanitary problem in that dirt, washing water, etc. accumulate in this recess f, and the fixing tool protrudes to the outside, so it is not safe. There was a problem that it not only lacked appearance but also lost its design value.

This invention was made with the intention of solving the above problem, and it is possible to easily connect the corrugated surface plate and the panel frame material through a connecting member that is connected with a fixing device to the back of the recess of the corrugated surface plate. In addition to being connected, the convex portion of the corrugated surface plate can be closed by the end piece formed on the connecting member, and the fixing member of the connecting member is designed not to protrude outside as much as possible. The present invention aims to provide an insulating panel with a corrugated surface.

Embodiments of this invention will be described below with reference to FIGS. 2 to 4.

FIGS. 2 and 3 show a cross-sectional perspective view and an exploded perspective view of the first embodiment of the panel of this invention, in which a flat surface plate 1, a recess 2a and a projection 2b A heat insulating core material 3 such as foamed polyurethane is filled between both surface plates 1 and 2, and a connecting groove 4a is formed in the center of the edge of the core material 3. The corrugated surface plate 2 and the panel frame material 4 are connected by a connecting member 5.

The connecting member 5 forms a back piece 5a that comes into contact with the back surface of the end of the wave-shaped surface plate 2 and is connected to the back surface of the recess 2a of the wave-shaped surface plate 2 by a fixing device 6 such as a rivet. At the end of this back piece 5a, a fitting protrusion 5b and an end face piece 5C capable of closing the convex portion 2b of the corrugated surface plate 2 are formed back to back, substantially perpendicular to this back piece 5a. When assembling the panel, the end of the convex portion 2b of the corrugated top plate 2 is closed by the end piece 5C of the connecting member 5, and the back piece 5a is placed on the back side of the concave portion 2a of the corrugated top plate 2. After abutting and fixing with a fixture 6 such as a blind rivet, the fitting protrusion 5b of the connecting member 5 is fitted into the groove 4b formed in the side part of the panel frame material 4,
The corrugated surface plate 2 and the panel frame material 4 are connected.

In this case, if a sealing member 7 made of rubber or soft synthetic resin is attached to the back surface, that is, the closed side surface, of the end piece 5c of the connecting member 5, the end of the protrusion 2b can be more securely closed by the end piece 5C. can be done.

Further, if a groove 5d for attaching the fixing device is formed in the back piece 5a, attachment of the fixing device 6 will be facilitated.

On the other hand, the connecting piece 1a bent at the end of the flat surface plate 1 is similarly fitted into the groove 4b of the panel frame material 4.
It is designed to be connected to the panel frame material 4.

The heat insulating core material 3 is foamed and filled into the space formed by the pair of flat surface plate 1 and corrugated surface plate 2 assembled as described above, the panel frame material 4 and the connecting member 5. This results in an insulated panel with a wavy surface.

In the above embodiments, only one of the surface plates is wavy, but the same effect can be obtained even if both of the surface plates are formed into a wavy shape.

Further, although the above embodiment shows a case where the connecting groove 4a is formed in the panel frame material 4, a panel frame material 4' having a connecting groove 4a' that can be engaged with the connecting groove 4a may also be used. It can be formed similarly.

(See Figure 4). As explained above, the heat insulating panel of this invention is similar to that of a normal panel by simply connecting the back surfaces of the connecting members that come into contact with the back surfaces of the recesses at the ends of the corrugated face plate formed on at least one side using fixtures. By assembling work similar to the above, the convex portion of the corrugated surface plate can be closed with the end piece of the connecting member, and the connecting member is hardly visible from the outside, and the fixing tool protrudes to the outside. This makes it look good on the outside, and even when the panel is used at the corner of a floor and wall, no dents will form.
For example, it has the advantage of being convenient in terms of hygiene when used in refrigerators, clean rooms, etc., as well as being safe because the fixings do not protrude, and having an excellent design effect. , its utility value is remarkable.
