Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to the improvement of heat-insulating composite panels used for the side walls and ceilings of prefabricated refrigerators and freezers, for example.

[Conventional technology]

In general, this type of composite panel has a corrugated surface plate on one of a pair of opposing surface plates in order to provide strength and a load-handling effect, and the corrugated surface plate located on the inner surface has a wall protection layer. A type consisting of a series of sliding plates is used. In this case, a flat plate was connected to the end of the wavy surface plate in order to make the line of intersection with the floor a straight line and to facilitate connection with other panels. Therefore, as shown in FIG. 4, in the conventional composite panel, a flat plate b is connected to a corrugated surface plate a, and one end of the flat plate b is connected to a horizontal plate that closes the corrugated opening end of the corrugated surface plate a. Bend the piece c and the mounting piece e which is fixed from the tip of this horizontal piece c to the inner surface of the end of the continuous side of the corrugated surface plate a with fixing means d such as rivets, and It has a structure in which a mounting piece f is bent at the other end, and this mounting piece f is inserted and fixed into a groove h provided in the panel end frame g, and the corrugated surface plate a and the flat surface plate are connected to each other. A heat insulating core material i, such as foamable urethane, was filled between the face plate b and the other face plate (not shown).

[Problem that the invention attempts to solve]

However, in conventional composite panels of this type,
Since the attachment part to the corrugated surface plate a, that is, the horizontal piece c and the attachment piece e are integrally formed on the flat plate b,
High precision was required for processing, and assembly was troublesome, requiring skill.

[Means for solving problems]

This invention was made with the intention of solving the above-mentioned problem, and its purpose is to make one of a pair of facing surface plates a wavy surface plate, and to make the wavy surface plate In an insulating composite panel comprising a flat plate connected to the end of the flat plate, and an insulating core material filled between the wavy face plate and the flat plate and the top plate, both ends of the flat plate are connected to each other. The locking pieces are bent to form a groove formed in the L-shaped intermediate frame material and a groove formed in the end frame of the panel, respectively. The present invention aims to provide a heat insulating composite panel that can be inserted and fixed into the interior of the vehicle.

[Effect]

The heat insulating composite panel of this invention constructed as described above operates as follows. That is, the locking pieces of the flat plate are inserted into the grooves provided in the intermediate frame member and the panel end, which are fixed in advance to the continuous end of the corrugated surface plate using fixing means such as rivets. By fixing, the corrugated surface plate and the flat plate can be connected easily and reliably, and
It is characterized by the fact that it can be easily assembled without requiring any skill.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 shows a cross-sectional view of the heat insulating composite panel of this invention when it is used as a side wall panel.The main parts are a pair of face plates 1 and 2 which face each other, and this wave shape surface. It is made up of a heat insulating core material 4, such as foamed urethane, filled between a flat plate 3 connected to the face plate 2, and a panel end frame 5 made of synthetic resin or the like placed around the end of the core material 4. It is. In this case, the wavy surface plate 2 and the flat plate 3 are connected to each other via an L-shaped intermediate frame member 6 made of synthetic resin. That is, the L-shaped intermediate frame member 6 includes a mounting piece 8 fixed to the inner surface of the continuous side end of the corrugated surface plate 2 with fixing means 7 such as rivets, and a continuous side end of the mounting piece 8. A closing piece 9 that is bent at a substantially right angle from the end and closes the wavy opening end of the wavy surface plate 2.
and a flat plate 3 on both sides of the outer side of the closing piece 9.
A locking piece 10 is bent at a right angle from the continuous end of the locking piece 10.
A concave groove 11 is formed into which the holder is inserted and fixed. The flat plate 3 is formed by bending locking pieces 10 at right angles at both ends of the connecting side, and one of the locking pieces 10 is inserted and fixed into the groove 11 of the L-shaped intermediate frame member 6. is,
Further, the other locking piece 10 is similarly fitted and fixed in a groove 12 formed in the panel end frame 5.

On the other hand, locking pieces 13 are also bent around the four circumferences of the flat surface plate 1, and these locking pieces 13 are fitted and fixed in grooves 12 provided in the panel end frame 5. .

The panel end frame 5 is formed with a convex portion 5a or a concave portion 5b that can be fitted into each other in order to connect adjacent panels (see FIG. 2).

When assembling the composite panel of this invention constructed as described above, first, as shown in Figure 2,
The locking pieces 13 of the surface plate 1 are fitted and fixed into the grooves 12 of the panel end frame 5, respectively. Next, fixing means 7 such as rivets or adhesives are attached to the inner surface of the continuous end of the corrugated surface plate 2, and the L-shaped intermediate frame member 6 is attached.
Then, the locking piece 10 of the flat plate 3 is inserted and fixed into the groove 11 provided in the L-shaped intermediate frame member 6 and the groove 12 provided in the panel end frame 5. At this time, the bent piece 2a at the end of the waveform surface plate 2 in the direction along the waveform direction is also
Insert and fix into 2.

In this way, the surface plate 1, the corrugated surface plate 2, and the flat plate 3 are placed in a state where they face each other with an interval between them. In this state, multiple stages are set, and each surface plate 1
After injecting an insulating material 5 such as foamable urethane between the wavy surface plate 2 and the flat plate 3, the insulation material 5 is foamed, and the assembly work of the composite panel as shown in FIG. 3 is completed.

In addition, although the above-mentioned embodiment explained the case where the flat plate 3 is continuously provided at the lower end of the side wall panel, the flat plate 3 does not necessarily have to be provided only at the lower end, and may be similarly provided continuously at the upper end. It goes without saying that the composite panel of this invention can also be used for ceiling panels, floor panels, partition panels, etc. other than side wall panels.

〔effect〕

As explained above, according to the composite panel of this invention, the concave grooves in the L-shaped intermediate frame member fixed to the continuous side end of the corrugated surface plate and the concave grooves provided in the panel end frame. The corrugated surface plate and the flat plate can be connected to each other by simply inserting and fixing the locking pieces bent into the flat plate, respectively, so that the following effects can be obtained. That is, 1. The bending process of the surface plate is simple, and high precision is not required, making the process easy.

2. After fixing the L-shaped intermediate frame material to the corrugated surface plate, the flat plate is simply inserted, making the panel assembly work simple.

3. Since the edge of the corrugated surface plate is supported by the L-shaped intermediate material, it will not sag or come off the panel edge frame, and the product dimensions will be accurate.

4. Furthermore, since no skill is required for the assembly work, it is possible to mass-produce the corrugated composite panel at low cost, and the quality can be improved compared to conventional panels of this type.
