Abstract
Abstract A foam block wall system is formed from a plurality of interconnected individual foam blocks. The individual foam blocks have a plurality of vertically oriented, quadrilateral core members spaced evenly within the block. The spaces between the core members define a plurality of vertically oriented chambers which receive liquid concrete. A plurality of connectors serve to connect the individual blocks into an integrated structure. A generally U-shaped bracket is secured to the floor or other supporting structure to provide support for the bottom layer of blocks. A generally H-shaped connector rests between successive vertical layers to provide both vertical and lateral stability. Generally U-shaped connectors connect adjacent blocks to provide vertical and lateral stability. A cabling system secures the individual blocks to the floor, also providing vertical and lateral support.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
303 words
A block system for receiving concrete, comprising: a plurality of blocks including a first block, a second block and a third block, each of said blocks having a height and a length; a vertical connector for interconnecting said first and second blocks with said second block being vertically above said first block, said vertical connecter including means disposed outwardly of portions of said first and second blocks for controlling movement of said second block relative to said first block in a direction substantially perpendicular to said height of said first block; a lateral connector for interconnecting said first block and said third block with said third block being laterally adjacent to said first block, said lateral connector for controlling movement of said third block relative to said first block in a direction substantially perpendicular to said height of said first block; and reinforcing rod means extending along at least a substantial majority of said lengths of said first and third blocks; wherein each of said first and third blocks includes first and second sidewalls located at ends of each of said first and third blocks, said lateral connector including a platform having a length and at least a first leg that join together said second sidewall of said first block and said first sidewall of said third block and with said platform having a length that extends substantially less than said length of said first block and extends substantially less than said length of said third block, said first leg extending along a height of said second sidewall of said first block and in which said reinforcing rod means has a substantially greater length than said platform and said length of said platform terminates adjacent to each of said second sidewall of said first block and said first sidewall of said third block.
Claim 2
Dependent Claim
303 words
A block system for receiving concrete, comprising: a plurality of blocks including a first block, a second block and a third block, each of said blocks having a height and a length; a vertical connector for interconnecting said first and second blocks with said second block being vertically above said first block, said vertical connecter including means disposed outwardly of portions of said first and second blocks for controlling movement of said second block relative to said first block in a direction substantially perpendicular to said height of said first block; a lateral connector for interconnecting said first block and said third block with said third block being laterally adjacent to said first block, said lateral connector for controlling movement of said third block relative to said first block in a direction substantially perpendicular to said height of said first block; and reinforcing rod means extending along at least a substantial majority of said lengths of said first and third blocks; wherein each of said first and third blocks includes first and second sidewalls located at ends of each of said first and third blocks, said lateral connector including a platform having a length and at least a first leg that join together said second sidewall of said first block and said first sidewall of said third block and with said platform having a length that extends substantially less than said length of said first block and extends substantially less than said length of said third block, said first leg extending along a height of said second sidewall of said first block and in which said reinforcing rod means has a substantially greater length than said platform and said length of said platform terminates adjacent to each of said second sidewall of said first block and said first sidewall of said third block.
Claim 3
Dependent Claim
164 words
A block system for receiving concrete, comprising: a plurality of blocks including a first block and a second block with each of said blocks having a height that extends in a vertical direction; a vertical connector for interconnecting said first and second blocks with said second block being vertically above said first block, said vertical connector including first and second retaining members disposed outwardly on opposite sides of said first and second blocks for controlling movement of said second block relative to said first block, each of said first and second retaining members includes an opening with said openings being aligned to receive a support cable, with portions of said support cable being received through each of said openings for supporting said first block during receipt of concrete, and in which said support cable extends outwardly at an angle and downwardly relative to said first and second blocks and with said support cable terminating at a location distant from said first and second blocks.
Claim 4
Dependent Claim
164 words
A block system for receiving concrete, comprising: a plurality of blocks including a first block and a second block with each of said blocks having a height that extends in a vertical direction; a vertical connector for interconnecting said first and second blocks with said second block being vertically above said first block, said vertical connector including first and second retaining members disposed outwardly on opposite sides of said first and second blocks for controlling movement of said second block relative to said first block, each of said first and second retaining members includes an opening with said openings being aligned to receive a support cable, with portions of said support cable being received through each of said openings for supporting said first block during receipt of concrete, and in which said support cable extends outwardly at an angle and downwardly relative to said first and second blocks and with said support cable terminating at a location distant from said first and second blocks.
Claim 5
Dependent Claim
42 words
A system, as claimed in claim 1, wherein: said vertical connector includes at least a first retaining member positioned on an outside surface of said first block and extending in a direction substantially parallel to said height thereof into said second block.
Claim 6
Dependent Claim
54 words
A system, as claimed in claim 1, wherein: said first block includes upper edges having a channel defined therebetween and said third block includes upper edges having a channel defined therebetween with said lateral connector being located in each of said first and third block channels for interconnecting said first and third blocks together.
Claim 7
Dependent Claim
41 words
A system, as claimed in claim 1, wherein: said first block includes a first panel, a second panel and a plurality of core members connected between said first and second panels, each of said core members being substantially quadrilateral in shape.
Claim 8
Dependent Claim
46 words
A system, as claimed in claim 1, further comprising: an exterior connector joined to said first block and extending along at least a portion of said height of said first block, said exterior connector for connecting an element to an outer surface of said first block.
Claim 9
Dependent Claim
54 words
A system, as claimed in claim 1, wherein: said first block includes a first panel and a first core member section integrally formed with said first panel and a second panel having a second core member section integrally formed therewith, said first core member section and said second core member section being connected together.
Claim 10
