Abstract
A loadbearing construction element consisting of outer shells which define an air-tight cavity in which is supported insulating elements which form collectively an inner unit. Means are provided for evacuating the cavities of the inner unit and for subsequently pressurizing the components of the inner unit to form a composite core the components of which are fixedly connected to each other. Pressure against the components of the inner unit can be increased by adjustable screws extending through the outer shell into contact with a pressure plate forming part of the inner unit. In this manner, stresses in the element are created so that the outer shells and the components of the inner unit are reinforced and rendered resistant to bending.
Claims17
A load-bearing construction unit comprising
- a. outer composite shell assemblies of high flexural strength forming the sides of said unit, border assemblies comprising the top and bottom of said unit, said shell and border assemblies defining a cavity therewithin,
- b. composite supporting plates positioned within said outer shell assemblies,
- c. an intermediate load-bearing composite group disposed in said cavity between and spaced from said outer shell assemblies,
- d. cellular web assemblies disposed between said intermediate composite group and said composite supporting plates, the lateral edges of said web assemblies being tightly and compressively engaged by said intermediate composite group and said composite supporting plates thereby to seal off the individual cells in said web assemblies, whereby the desired pressure conditions can be maintained in said web assemblies,
- e. first screw means extending through said unit for stressing said outer shell assemblies, and
- f. second screw means applying compressive pressure to the remaining elements within said cavity.
A load-bearing construction unit comprising
- a. an outer shell of reinforced concrete and an opposite outer shell defining the boundary of a room or the like, said shells being spaced to define a cavity therebetween,
- b. perforated shell members spaced within and from said outer shells,
- c. a central shell positioned within said cavity in spaced relation from said perforated shell member,
- d. cellular web assemblies positioned between said perforated shell members and said central shell,
- e. inflatable hose means positioned between said outer shells and said perforated shells and adapted to expand so as to provide pressure contact of said perforated shells with said cellular web assemblies, and
- f. means to evacuate a substantial part of the space between said outer shells and said perforated shells for providing a predetermined air condition within said cavity, and additional means to first evacuate and then pressurize said inflatable hose means, with such pressurization acting through said perforated shells and said cellular web assemblies to place said cellular web assemblies to place said central shell under compressive stress.
