Claims
- 1. A block for use in interlocking with other similar blocks in constructing a building comprising:a block body having a top surface and a bottom surface, the block body having: an outer block wall defining one side surface of the block body; a head portion extending from the outer block wall toward an opposed side surface; and two connecting portion on a respective side of the head portion; two abutment portions each at a respective end of the outer block wall and each defining a respective abutment shoulder; and a single central groove in the head portion at a position thereon opposite to the outer block wall, the groove at opposite ends thereof defining two inwardly facing shoulders each for engaging and retaining the abutment portion of a respective one of two abutting blocks such that the abutment portions are retained end to end within the single groove; wherein there is defined between the abutment portion and the connecting portion a receptacle substantially matching in shape the connecting portion for receiving in interlocking relationship the connecting portion of a co-operating interlocking block.
- 2. The block according to claim 1 wherein the groove has shoulders substantially at right angles to the outer block wall.
- 3. The block according to claim 1 wherein the head portion has a hole centrally thereof and extending from the top surface to the bottom surface.
- 4. The block according to claim 1 wherein the connecting portions are lobe shaped.
- 5. An interlocking block system comprising a plurality of blocks arranged for use in interlocking with other similar blocks in constructing a building, at least some of the blocks comprising:a block body having a top surface and a bottom surface, the block body having: an outer block wall defining one side surface of the block body; a head portion extending from the outer block wall toward an opposed side surface; and two connecting portions each on a respective side of the head portion; two abutment portions each at a respective end of the outer block wall and each defining a respective abutment shoulder; and a single central groove in the head portion at a position thereon opposite to the outer block wall, the groove at opposite ends thereof defining two inwardly facing shoulders each for engaging and retaining the abutment portion of a respective one of two abutting blocks such that the abutment portions are retained end to end within the single groove; wherein there is defined between the abutment portion and the connecting portion a receptacle substantially matching in shape the connecting portion for receiving in interlocking relationship the connecting portion of a co-operating interlocking block.
- 6. The system according to claim 5 wherein the groove has shoulders substantially at right angles to the outer block wall.
- 7. The system according to claim 5 the head portion has a hole centrally thereof and extending from the top surface to the bottom surface.
- 8. The system according to claim 5 wherein the connecting portions are lobe shaped.
- 9. The system according to claim 5 including a joiner block having an element shaped the same as an abutment portion on the side of the head portion opposite to the outer block wall.
- 10. The system according to claim 5 including an end block substantially equal to one half of the other blocks.
- 11. A building wall comprising:a plurality of interlocking blocks, at least some of the blocks each comprising: a top surface; a bottom surface; an outer block wall defining a side surface of the block; a head portion extending from the outer block wall toward an opposed side surface; two connecting portions each on a respective side of the head portion; two abutment portions each at a respective end of the outer block wall and each defining a respective abutment shoulder on a face of the outer block wall opposite to the side surface thereof; two receptacles each arranged between a respective one of the abutment portions and a respective one of the connecting portions; and a single central groove in the head portion at a position thereon opposite to the outer block wall, the groove at opposite ends thereof defining two inwardly facing opposed shoulders; the blocks being arranged to define a first series of the blocks in which the side surface of each of the first series of blocks is arranged to form a first vertical side surface of the wall and a second series of the blocks which are rotated through 180 degrees in which the side surface of each of the second series of blocks is arranged to form a second vertical side surface of the wall opposite to the first vertical side surface; the blocks being interlocked such that: two abutment portions each of a respective one of two adjacent blocks of the second series fit into the single central groove in an opposed one of the blocks of the first series such that the abutment portions are retained end to end within the single groove; two abutment portions each of a respective one of two adjacent blocks of the first series fit into the single central groove in an opposed one of the blocks of the second series such that the abutment portions are retained end to end within the single groove; each receptacle of each of the first series of blocks is shaped to receive in interlocking relationship a respective one of the connecting portions of the second series of blocks; each receptacle of each of the second series of blocks is shaped to receive in interlocking relationship a respective one of the connecting portions of the first series of blocks.
- 12. The building wall according to claim 11 wherein the groove has shoulders substantially at right angles to the outer block wall.
- 13. The building wall according to claim 11 wherein the head portion has a hole centrally thereof and extending from the top surface to the bottom surface.
- 14. The building wall according to claim 11 wherein the connecting portions are lobe shaped.
- 15. The building wall according to claim 11 including a joiner block having an element shaped the same as an abutment portion on the side of the head portion opposite to the outer block wall.
- 16. The building wall according to claim 11 including an end block substantially equal to one half of the other blocks.
