Description

[Detailed Description of the Invention] This invention relates to an improvement of a heat insulating panel in which a heat insulating core material is filled between a pair of facing face plates.

Generally, this type of panel has a heat insulating core material such as foamed polyurethane filled between a pair of facing flat surface plates, but it has the drawback of being weak in strength.

Therefore, recently, panels have been developed in which the surface plate is made uneven to prevent deformation such as bending of the panel.

However, even with this type of panel, when the panel is used as a wall panel for a prefabricated refrigerator, for example, there is a problem that the convex part is deformed due to collision with luggage, pallets, etc. There was also the problem that it was weak against loads, and that sufficient care had to be taken in inventory management, transportation, etc.

This invention is intended to solve the above problem, and its gist is to create a hollow part along the groove in the groove on the back surface of the surface plate that is uneven along the width direction. In addition to attaching a reinforcing member with the reinforcing member, the hollow part of this reinforcing member is inserted into the insulating core material inside the panel from the groove on the back surface, thereby increasing the strength of the panel surface plate. , it is possible to save on the amount of relatively expensive insulating core material used, and it also provides an insulation function that utilizes air layers.
Furthermore, the present invention aims to provide a heat insulating panel that is easy to manufacture and lightweight.

Examples of this invention will be described below based on the drawings.

Figures 1 to 3 show a first embodiment of the heat insulating panel of this invention, in which a heat insulating core material 3, such as foamed polyurethane, is filled between a pair of face plates 1 and 2 facing each other.
In addition, one of the face plates 1 is formed in a continuous trapezoidal uneven shape along its width direction, and a reinforcing member 5 is attached to the convex part of the face plate 1, that is, the groove part 4 on the back surface. This is the case.

In this case, the reinforcing member 5 is formed into a hollow trapezoidal column shape, as shown in FIG. It is said that it will be rushed into.

In the heat insulating panel of this invention having such a structure, the reinforcing member 5 is attached and fixed by filling the insulating core material 3 with the reinforcing member 5 attached to the groove portion 4 on the back surface of the top plate 1. be.

In this case, an adhesive can be applied to the reinforcing member 5 to ensure an accurate attachment position to the surface plate 1.

Further, the hollow portion 6 is closed at both ends of the reinforcing member 5.

The same applies to the following examples. 4 to 7 show a second embodiment of this invention, in which the reinforcing member 5 can be more securely held.

That is, the anchor portions 7 or 7' are made to protrude from the side of the insulating core material of the reinforcing member 5, and a plurality of through holes 8, 8, . Due to the presence of the anchor part 7 or 7' that protrudes into the interior and the insulating core material 3 that penetrates into the through hole 8, displacement of the reinforcing member 5 is prevented,
This allows the reinforcing member 5 to be more firmly fixed.

In this case, in FIGS. 4 and 5, both sides of the reinforcing member 5 are extended to form the anchor part 7, and in FIGS. 6 and 7, the sides of the insulating core material of the reinforcing member 5 are extended on both sides. The anchor portion 7' has an outwardly directed flange shape and extends to the outside.

8 and 9 show a third embodiment of this invention, in which the side surface of the heat insulating core of the reinforcing member 5 is formed into a curved surface 5' projecting toward the heat insulating core 3.

By forming the reinforcing member 5 in this way, the hollow portion 6
By effectively utilizing the insulating effect of the air inside, it is possible to even out the heat bridge.

10 and 11 show a fourth embodiment of this invention, in which the shape of the convex portion of the surface plate 1 is made into a dovetail shape, which is opposite to the uneven shape of the surface plate 1 of the first to third embodiments. This is the case when

Therefore, since the reinforcing member 5 in this case has a hollow trapezoidal column shape as shown in FIG. ,
The reinforcing member 5 in the first embodiment can be reversed and used for the same purpose.

Figures 12 and 13 show a fifth embodiment of this invention, in which a surface plate 1 has a first groove 1a whose bottom is enlarged, and a second groove whose opening is enlarged. 111b are used alternately.

In this case, as shown in FIG. 13, the reinforcing member 5 has a flat part 5a that can come into contact with the bottom part of the back groove part 4 with respect to the center line A-A, and a flat part 5a that is inclined parallel to each other from both ends of the flat part 5a. If the cross-sectional shapes of the side parts 5b and 5b are symmetrical, one type of reinforcing member 5 can be used inverted in the two types of back grooves 4, and the function of preventing the reinforcing member 5 from slipping can be improved. can also have

Further, FIGS. 14 and 15 show a sixth embodiment of this invention, in which the surface plate 1 shown in the first to third embodiments is shown.
This is a case in which the reinforcing member 5 can be easily attached to the uneven shape without distinguishing between the front and the back.

That is, as shown in FIG. 15, the reinforcing member 5 is expanded from the flat part 5a that comes into contact with the bottom surface of the back groove part 4 of the top plate 1 with respect to the center line A-A, and from both ends of this flat part 5a. By making the side pieces 5c, 5c, which are inclined in the direction of the reinforcing member 5, have a symmetrical cross section, either half of the reinforcing member 5 can be attached to the inside of the back groove portion 4.

In each of the above embodiments, only one surface plate 1 has an uneven shape, but the other surface plate 2 has an uneven shape.
It is also possible to similarly form the reinforcing member 5 into an uneven shape and attach the reinforcing member 5 to the groove on the back surface formed in the surface plate 2. If formed in this way, the panel will be made stronger. In addition, it is possible to freely attach the panel without having to select the front and back sides of the panel.

Further, if the reinforcing member 5 is made of a heat insulating material such as synthetic resin, the heat insulating function of the panel can be improved.

As explained above, the heat insulating panel of this invention has at least one face plate shaped in an uneven shape along the width direction, and has a hollow part along the groove in the groove on the back side of the face plate. Since a reinforcing member is attached and the hollow part of this reinforcing member is inserted into the insulating core material, the strength of the panel's face plate can be increased, and the thickness of the face plate can be reduced compared to the conventional one. It can be made slightly thinner than the
Not only can it save on the amount of relatively expensive insulating core material used, it also has a heat insulating function that utilizes the sealed air layer in the hollow space, is easy to manufacture, and can be lightweight. It has a good effect.

Further, the hollow portion can be used for example as a wiring/piping space or an air duct, so its utility value is significant.
