Abstract
The composite wall element of this invention comprises an insulating wall element arranged within or inserted into an outer, pressure resistant, preferably load bearing wall element which completely encloses the former. Within the inner insulating wall element and/or the cavity within the outer wall element a substantially dry gas atmosphere and preferably air atmosphere is established and maintained under subatmospheric, atmospheric, or superatmospheric pressure. Such novel composite wall elements are superior in their thermal and/or acoustic insulation properties to heretofore known structural elements.
Claims16
In a composite wall element for thermal and acoustic insulation of walls, ceilings, floors and the like, comprising:
- a. an outer wall element, said outer wall element being pressure resistant and imparting to the composite wall element the requisite structural strength and integrity,
- b. an inner insulating wall element positioned within and enclosed by said outer wall element, said inner insulating wall element including
- 1. an outer continuous covering fitting tightly within said outer wall element, said covering being provided on its inner surface with means for vapor-tight sealing said covering,
- 2. first spacer means lining the interior of said covering and said sealing means to impart the desired shape and rigidity to said covering, the inwardly facing surfaces of said spacing means being provided with reflecting means which reflect toward the inner cavity formed by said spacer means,
- 3. a reflective foil positioned within said cavity and space from said reflecting means,
- 4. a plurality of spaced, second spacer means positioned on either side of said reflective foil and extending between said foil and said reflecting means, said second spacer means forming radiation chambers, and
- c. passage means communicating the interior of said composite element with the exterior thereof whereby a supply of air may be admitted to and exhausted from said radiation chambers.
A composite wall element for thermal and acoustic insulation of walls, ceilings, floors and the like, comprising:
- a. outer wall elements, said outer wall elements being pressure resistant and imparting to the composite wall element the requisite structural strength and integrity,
- b. an inner insulating wall element positioned within and enclosed by said outer wall elements, said inner insulating wall element including spacer means positioned in said inner insulating wall element to impart thereto the desired shape and rigidity, and anchoring means connecting opposed walls of the outer wall elements and extending through the inner insulating wall element, said anchoring means extending air-tightly through the inner insulating wall element and the opposed parts of the outer wall elements so as to increase the load-bearing capacity of the composite wall element, said anchoring means comprising a first anchor part having a threaded end portion and a second anchor part having a mating threaded opening for receiving said end portion of said first anchor part, and a disc mounted on each anchor part, with the spacing of said discs, one from the other, when the anchor parts are interconnected being such as to receive said inner insulating wall element therebetween, with the threaded engagement of said parts being such as to permit axial adjustment of said parts and thus the distance between said discs.
