Reference numeral 6 denotes a connecting member for connecting the end portions of the front and back face plates 4 and 5 to each other.
Has a cross section of approximately L,
It is formed in the shape of a letter .
The two fitting portions 6a and 6e are integrally formed. That is, the fitting portions 6a and 6e have a pair of upper and lower projecting pieces 6b and 6c facing each other, and one of the projecting pieces 6c having the projection 6d formed on the inner surface of the distal end is formed so as to be elastically deformable. .
For this reason, each of the first and second fitting portions 6a and 6e is provided with the first and second bent portions 4 of the front and back plates 4, 5 inserted from the front and back directions.
a, 5a , 4c, and 5c can be fitted from the front and back sides, respectively , and the fitted bent portions 4a, 5a , 4c, and 5c can be fitted.

By the way, the connecting member 6 for connecting the upper ends of the face plates 4 and 5 and the connecting member 6 for connecting the lower ends thereof are
It is formed in the same cross-sectional shape inverted upside down, so that one type can be used also as the upper and lower connecting members 6, but the connecting member 6 is also used as the heat insulating panel 1 having a different panel thickness. It is like that. That is, as shown in FIG. 4, heat insulation panels 1 having different thickness dimensions can be formed only by changing the width setting of the bent portions 4a, 5a , 4c, 5c .

Reference numeral 7 denotes a hermetic member made of a soft resin integrally formed with the connecting member 6. The hermetic member 7 is formed in a cross-sectional shape of a letter and integrated with one of the fitting portions 6a. Has been When the adjacent panels are in contact with each other, the hermetic member 7 comes into contact with the step portions 4b and 5b of the face plates 4 and 5 in a resilient manner so as to hermetically close the gap between the panel contact portions. I have.

Further, reference numeral 8 denotes a heat insulating material filled between the front and back plates 4 and 5, and the heat insulating material 8 is formed by injecting and foaming a so-called urethane foam. The urethane foam thus formed is integrally connected to the front and back plates 4 and 5 based on the adhesive strength so as to prevent the face plates 4 and 5 at the fitting portion 6a from being removed.

However, each of the face plates 4 and 5 is arranged in upper and lower steps to form a reciprocal structure.
First and second folds on each side of the front and back sides that are misaligned
Since the curved portions 4a, 5a, 4c, and 5c are formed of bent thin plates, there is no restriction on the size of the face plates 4, 5 as in the conventional case formed by extruded aluminum members. There is no. Therefore, the heat insulating panel 1 having a desired size can be formed without connecting a plurality of face plates. As a result, the structure can be simplified and the cost can be greatly reduced. Can be measured.
Moreover, in this case, the step-like portion where the heat insulating material 8 protrudes most is provided.

Moreover, since the steel plate, the stainless steel plate, the aluminum plate and the like can be freely selected as the thin plate material for forming the front and back plates 4 and 5, various heat insulating panels 1 of different materials can be provided. .

Further, since the front and back plates 4 and 5 are fitted into the fitting portion 6a of the connecting member 6 in a plug-in manner from the front and back sides, the connecting member is slidably mounted from the side. There is also an advantage that the assemblability can be remarkably improved as compared with the above, or the processing error of the front and back plates 4, 5 can be absorbed by changing the fitting amount.

The elastically deformable protruding piece 6c formed on the fitting portion 6a receives the foaming pressure during foaming of the heat insulating material 8, and receives bent portions 4a, 5a , 4c, 4c of the face plates 4, 5 . 5
c , the insulating material 8 being foamed from between the protruding piece 6c and the bent portions 4a, 5a , 4c, 5c.
Can be reliably prevented from leaking out, and furthermore, as shown in FIG. 5, an elastically deformable protruding piece 6c is provided so as to be located on the inner side of the panel at both fitting portions 6a. In this case, the leakage of the heat insulating material 8 is caused by the two fitting portions 6a ,
6e, 6e .

Further, the connecting member 6 of the above embodiment is
By inverting the upper and lower portions, the connecting members at both upper and lower ends can be used not only as the connecting members but also as the heat insulating panel 1 having a different panel thickness. Therefore, the manufacturing cost is lower than when manufacturing various connecting members. Can be greatly reduced, and parts management can be simplified, which can greatly contribute to cost reduction of the heat insulating panel 1.
