Abstract

Abstract An insulating inner panel and an outer panel are assembled together so as to form an internal space which is subsequently filled with light concrete. U-section members or flanged channel bars having uniformly spaced slots are flush-mounted within superposed horizontal channels of the inner panel. At the ends of the wall, metallic fastening pins pass through the slots and the insulating panel and pass round upright members forming part of vertical end beams against which the inner panel is applied. Between the wall ends, the fastening pins are each constituted by a loop having twisted ends and two free end portions which are passed through packing-blocks placed within the internal space and are anchored in the outer panel.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 216 words
A prefabricated wall primarily for the construction of dwelling houses and comprising an insulating inner panel and an outer panel assembled together by coupling means so as to form between said panels an internal space which can subsequently be filled with no-fines or light concrete, wherein the insulating inner panel is provided with superposed horizontal channels fitted with U-section members or flanged channel bars having uniformly spaced slots and flush-mounted within said channels, and wherein the coupling means are provided at the ends of the wall with metallic fastening elements which pass through the slots as well as the insulating material and extend on each side of vertical upright members forming part of end beams against which the internal panel is applied, said fastening elements being bent back within the sectional members whilst the coupling means provided between the ends of said panels comprise a series of metallic fastening pins disposed at intervals and each constituted by a loop, the ends of said loop being twisted and provided with two free end extensions, the fastening pins being positioned in such a manner that the loops of said pins pass through the insulating inner panel whilst the free ends of said pins pass through packing-blocks placed within the internal space and are anchored in the outer panel.
Claim 2
Dependent Claim 216 words
A prefabricated wall primarily for the construction of dwelling houses and comprising an insulating inner panel and an outer panel assembled together by coupling means so as to form between said panels an internal space which can subsequently be filled with no-fines or light concrete, wherein the insulating inner panel is provided with superposed horizontal channels fitted with U-section members or flanged channel bars having uniformly spaced slots and flush-mounted within said channels, and wherein the coupling means are provided at the ends of the wall with metallic fastening elements which pass through the slots as well as the insulating material and extend on each side of vertical upright members forming part of end beams against which the internal panel is applied, said fastening elements being bent back within the sectional members whilst the coupling means provided between the ends of said panels comprise a series of metallic fastening pins disposed at intervals and each constituted by a loop, the ends of said loop being twisted and provided with two free end extensions, the fastening pins being positioned in such a manner that the loops of said pins pass through the insulating inner panel whilst the free ends of said pins pass through packing-blocks placed within the internal space and are anchored in the outer panel.
Claim 3
Dependent Claim 103 words
A prefabricated wall as claimed in claim 1, wherein the intermediate packing-blocks are disposed at intervals between the ends of the panels and wherein the vertical end beams which provide a connection between the panels at the ends of said panels each have at least two upright members such that one member is embedded in the outer panel whilst the other member is located within the internal space, and wherein the free ends of each fastening pin surround said two upright members and are bent-back around the upright member which is embedded in the outer panel, said outer panel being constructed of concrete.
Claim 4
Dependent Claim 48 words
A prefabricated wall as claimed in claim 1, wherein the loops of the fastening pins pass through the slots of the sectional members, are bent-back within said sectional members and are twisted around a rod which is engaged in the loop within the interior of the sectional member.
Claim 5
Dependent Claim 94 words
A prefabricated wall as claimed in claim 1, wherein the end beams comprise three upright members disposed in a triangle, said members being interconnected by means of a wire framework, two of said upright members being embedded in the outer concrete panel, and wherein the free ends of each of the metallic fastening pins which are associated with a beam embrace the upright member which is placed within the internal space then pass around the two upright members which are embedded in the concrete, said pins being then bent-back around said two upright members.
Claim 6
Dependent Claim 35 words
A prefabricated wall as claimed in claim 1, wherein said wall is employed as a platform roof or as a floor in which the internal space is not filled with concrete and provides horizontal ventilation.
Claim 7
Dependent Claim 66 words
A prefabricated wall as claimed in claim 5, wherein the packing-blocks housed within the internal space between the two panels have increasing heights from one edge of the wall to the other in order to give a predetermined slope to the top insulating panel, the metallic fastening pins being such as to have increasing lengths as a function of the progressively increasing heights of the packing-blocks.
Claim 8
Dependent Claim 57 words
A prefabricated wall as claimed in claim 1, wherein the outer panel is constituted by a shutter traversed by the free ends of the metallic fastening pins, the space formed between the shutter and the inner panel being filled with concrete, whereupon the projecting extremities of the free ends are cut off and the shutter is removed.
