Abstract: A heat-insulated wall has two outer covering layers which are disposed at a distance from one another and are constructed at least substantially vacuum-tight. The two outer covering layers are connected to one another in a vacuum-tight manner by a connecting profile that runs along their contour and has a U-shaped cross section. The two outer covering layers together with the connecting profile enclose an intermediate space that can be evacuated and filled with an evacuable heat insulating material. At least one tubular bushing for cables or the like runs through the intermediate space. The bushing connects apertures to one another that are formed the spaced-apart outer covering layers. The tubular bushing is provided on its two end sections with a flange-shaped expanded and flattened region by which the bushing is fixed in a vacuum-tight manner on the mutually facing inner sides of the two outer covering layers.

Abstract: A heat insulated wall having two surface layers disposed at a distance from one another and are at least substantially vacuum-tight in construction. The two surface layers together with an at least substantially vacuum-tight connection element enclose an evacuable space that is filled with an evacuable thermal insulation material. The surface layers have angled sections with free ends directed away from the space and on which the connection element is disposed and is fastened in a vacuum-tight fashion to the angled sections.

Abstract: A heat-insulating wall has two spaced-apart, at least essentially vacuum-tight cover layers, between which an evacuable heat-insulation material is provided and which are connected to one another by a vacuum-tight connecting profile which runs along the free edges of the cover layers. The connecting profile has a membrane which spans at least essentially the distance between the cover layers. The connecting profile is made up of a plurality of profile sections adjoining one another in a vacuum-tight manner. At the adjoining ends of the profile sections, the membrane has an end section with a thickness of at least approximately the material thickness of the cover layers.

Abstract: A heat insulation wall has two outer surface layers disposed at a distance from one another; the outer surface layers have a contour and are at least substantially vacuum-tight. The heat insulation wall has a connecting profile which extends along the contour, connects the two outer surface layers in a vacuum-tight fashion, and encloses, together with the two outer surface layers, an evacuable space. The connecting profile is composed of a plurality of profile sections. An evacuable thermal insulation material is filled in the evacuable space. A support element is fastened to the outer surface layers and serves as a bearing for the profile sections. The profile sections are supported on the support element and are connected to the support element in a vacuum-tight fashion.

Abstract: A heat-insulated wall is formed of two covering layers configured to be substantially vacuum-tight and are disposed at a distance from one another. The two covering layers are connected to one another by a connecting profile that runs along their contour and has a U-shaped cross-section. The two covering layers together with the connecting profile, enclose an intermediate space which can be evacuated and filled with heat-insulating material which can also be evacuated. The U-shaped connecting profile is equipped with limbs whose material thickness is at least approximately in the same order of magnitude as the material thickness of the covering layers, and has a base which connects the two limbs and is configured like a sheet.

Abstract: A thermally insulated housing has a substantially vacuum-tight outer shell and an at least substantially vacuum-tight inner enclosure that is spaced apart from the outer shell. The elements are connected to one another in a vacuum-tight fashion by a connection section that is at least approximately U-shaped in cross section and which is secured by its section limbs to the outer shell on the one hand and to the inner enclosure on the other by welding. A point of connection of the limbs of the U-shaped connection section to the outer shell or to the inner enclosure is thickened. The thickened area has at least essentially the thickness of material of the inner enclosure or of the outer shell.
