2. Description of the Related Art Conventionally, a corner heat insulating panel of this type is composed of a first side wall portion and a second side wall portion which is continuous at right angles to the first side wall portion,
The connecting side end of the upper and lower frame members of the first side wall portion and the connecting side end of the upper and lower frame members of the second side wall portion are butted against each other, and two vertical frame members are provided for these upper and lower frame members, It was manufactured by combining two aluminum surface plates and setting them with a jig, and then filling a hollow portion formed inside these panel constituent members with a heat insulating material by injection foaming.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the conventional heat insulation panel for corners, the connecting end portions of the upper frame member and the connecting end portions of the lower frame member are simply butted together, and these connecting ends are 45 because the first and second side walls are connected at right angles.
Since it is cut every time and its length is longer than the thickness of the panel (thickness of the side wall), the abutting part of the frame material opens due to the foaming pressure during the injection foaming of the heat insulating material, The heat insulating material may leak, and the leaked heat insulating material adheres to the surface plate, which may cause discoloration or damage to the surface plate. Moreover, the processing of the leaked heat insulating material was troublesome.

Therefore, conventionally, when the above panel constituent members were combined, these were strongly tightened with a jig, but if the tightening with such a jig is too strong, the thickness of the panel after the heat insulating material is molded is expected. However, there is a problem that the dimensional stability is poor and the product is less likely to vary because the panel thickness varies depending on the tightening condition of the jig.

Conventionally, especially when the panel thickness is large, such as a heat insulation panel for refrigeration, the abutting portions of the connecting ends of the upper and lower frame members are integrally joined by welding in advance to prevent deformation during injection foaming. However, there is a problem in that such welding work is very troublesome and time-consuming, and thus the heat insulation panel for corners cannot be easily and inexpensively manufactured.

The object of the present invention is to solve the above-mentioned conventional problems and to reliably prevent the deformation of the abutting portions of the upper and lower frame members during the injection and foaming of the heat insulating material, which may cause leakage of the heat insulating material at all. Therefore, it is an object of the present invention to provide a heat insulating panel for a corner, which has a high dimensional accuracy and a uniform quality, and can be manufactured extremely easily and inexpensively.

According to this invention, in any of the above cases, it is possible to reliably prevent deformation of the abutting portions of the upper and lower frame members during the injection foaming of the heat insulating material, and to prevent leakage of the heat insulating material. Therefore, the resulting corner insulation panel has high dimensional accuracy and uniform quality. Moreover, it is only necessary to fit the connecting reinforcing member to the connecting ends of the upper and lower frame members, or to insert the insertion portions at both ends of the connecting reinforcing member inside the connecting ends of the upper and lower frame members. Since the welding step of the material end portion can be omitted, there is an effect that it is possible to manufacture the corner heat insulating panel very easily and inexpensively.
