Abstract
Abstract A method of constructing in-situ cast concrete, internally insulated building walls, comprises the steps of erecting a wall mold having a pair of vertical, spaced, mold plates, introducing between, distanced from, and extending from bottom to top of the mold plates, an assembly comprising a rigid back-up panel and at least one board of insulating material releasably attached to one side of the panel, filling with poured concrete the spaces formed between the mold plates and the assembly, and before the concrete hardens, extracting the panel from the cast wall so that the board remains and becomes embedded in the concrete. Two such insulating boards may be releasably attached to both sides of the panel, so that upon the extraction of the panel, the boards will gradually approach each other under the hydrostatic pressure of the concrete in which they are submerged, thus forming a substantially unified insulation layer.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
105 words
A method of constructing in-situ cast concrete, internally insulated building walls, comprising the steps of: (a) erecting a wall mold having a pair of vertical, spaced, mold plates; (b) introducing between, distanced from, and extending from bottom to top of the mold plates, an assembly comprising a rigid back-up panel and at least one board of insulating material releasably attached to one side of said panel; (c) filling with poured concrete the spaces formed between said mold plates and said assembly; and (d) before the concrete hardens, extracting said panel from the cast wall so that said board remains and becomes embedded in the concrete.
Claim 2
Independent Claim
105 words
A method of constructing in-situ cast concrete, internally insulated building walls, comprising the steps of: (a) erecting a wall mold having a pair of vertical, spaced, mold plates; (b) introducing between, distanced from, and extending from bottom to top of the mold plates, an assembly comprising a rigid back-up panel and at least one board of insulating material releasably attached to one side of said panel; (c) filling with poured concrete the spaces formed between said mold plates and said assembly; and (d) before the concrete hardens, extracting said panel from the cast wall so that said board remains and becomes embedded in the concrete.
Claim 3
Dependent Claim
56 words
The method as claimed in claim 1 wherein said assembly comprises a second board of insulating material releasably attached to the other side of the panel, so that after the panel has been extracted from between the boards, the boards are moved towards each other by the unhardened concrete to form a substantially unified insulation layer.
Claim 4
Dependent Claim
25 words
The method as claimed in claim 1, including the further step of casting a ceiling over the wall immediately after the extraction of the panel.
Claim 5
Dependent Claim
21 words
The method as claimed in claim 1, including the further step of vibrating the concrete after the extraction of the panel.
Claim 6
Dependent Claim
29 words
The method as claims in claim 1, including the further step of releasably clamping the board(s) to the panel, to releasably hold the assembly together during the handling thereof.
Claim 7
Dependent Claim
15 words
The method as claimed in claim 1, wherein said panel is of corrugated sheet metal.
Claim 8
Dependent Claim
14 words
The method as claimed in claim 6 wherein said board is of foamed plastics.
Claim 9
Dependent Claim
22 words
The method as claimed in claim 1 wherein one of said mold plates constitutes one side wall of a concrete casting tunnel.
Claim 10
Dependent Claim
50 words
The method as claimed in claim 1, including the further steps of preparing a channel-like recess at the bottom of the wall for receiving the lower edge of the assembly between the mold plates, and providing spacer means for holding the upper edge of the assembly between the mold plates.
Claim 11
Dependent Claim
41 words
The method as claimed in claim 9 wherein a plurality of successively side-by-side arranged assemblies are provided for completing the wall, bolts being provided between successive assemblies, extending between the mold plates and passing through extended marginal portions of said board(s).
