Abstract
A plurality of especially configured cementitious blocks arranged in a modular array with at least one planar polyurethane foam panel cast and cured in situ within the blocks to fusingly bond the blocks together and provide the modular array with an integral coextensive uninterrupted thermally insulative barrier.
Claims16
A thermally insulative cementitious block module comprising:
- (a) a plurality of cementitious blocks arranged in an aligned desired modular array so that each of said blocks is in abutting engagement with at least another one of said blocks, each of said blocks defining at least one passage which extends the full length and height thereof, said passages of said plurality of blocks being in alignment with each other;
- and
- (b) a polyurethane foam panel cast and cured in situ within said aligned passages of said plurality of blocks to provide said modular array with a one piece uninterrupted coextensive thermally insulative barrier which fusingly bonds said plurality of blocks into said modular array.
A thermally insulative cementitious block module comprising:
- (a) a plurality of cementitious blocks each including,
- I. a central body portion having an opposed pair of longitudinal surfaces, and
- II. a face panel in spaced coextending relationship with one of the longitudinal surfaces of said central body portion to define a coextensive passage between that longitudinal surface of said central body portion and said face panel;
- (b) said plurality of cementitious blocks arranged in a modular array so that each of said blocks is in abutting engagement with at least another one of said blocks, said plurality of cementitious blocks aligned with respect to each other so that the passages defined in each of said blocks are in alignment;
- and
- (c) a polyurethane foam panel cast and cured in situ within the aligned passages defined by said plurality of cementitious blocks to fusingly bond said blocks into the modular array and form a one piece uninterrupted integral thermally insulative barrier which is coextensive with the modular array.

A method of making a cementitious block module having at least one thermally insulative one piece panel formed integrally therein so as to be uninterrupted and coextensive therewith, said method comprising the steps of:
- (a) casting and curing a plurality of cementitious blocks each having a central body portion with an opposed pair of longitudinal surfaces and a face panel spaced from and coextensive with one of the longitudinal surfaces thereof to define a coextensive passage between said central body portion and said face panel, said central body portion and said face panel interconnected by at least one thin wall web;
- (b) placing said plurality of cementitious blocks in an open top holding fixture so that said blocks are arranged in a modular array with the coextensive passages defined by said blocks being in alignment;
- (c) placing the chemical constituents which form polyurethane foam in the aligned passages defined by said plurality of cementitious blocks;
- and
- (d) curing the chemical constituents of step (c) in situ within the aligned passages defined by said plurality of cementitious blocks to fill those passages with polyurethane foam to fusingly bond said plurality of cementitious blocks into the modular array and provide a one piece coextensive uninterrupted thermally insulative barrier therein.
