Formwork

Abstract

A moulding apparatus is used to form building blocks. The apparatus includes a plurality of vertical formboards in a pair of opposed rows, each formboard being connected to an adjacent formboard by clamps and spaced apart from opposed formboard by one of a plurality of partitions, each partition being attached to both the opposed rows thereby spacing the opposed rows apart and forming a mould between a pair of adjacent partitions and a pair of opposed formboards. The partitioning apparatus is useable to cast blocks in a course by filling the moulds with a hardenable material, the partitioning apparatus being positionable above the previously moulded course of blocks, with the lower edges of the formboards overhanging the previously moulded course of blocks, wherein apparatus further includes an insulation insert which is adapted to be formed into said blocks in a course such that a wall formed by the multiple courses of blocks is continuous.

1 . A moulding apparatus including a plurality of vertical formboards in a pair of opposed rows, each said formboard being connected to an adjacent said formboard by clamping means and spaced apart from opposed said formboard by one of a plurality of partitions, each said partition being attached to both said opposed rows thereby spacing the opposed rows apart and forming a mould between a pair of adjacent partitions and a pair of opposed formboards, said partitioning apparatus being useable to cast blocks in a course by filling the moulds with a hardenable material, said partitioning apparatus being positionable above the previously moulded course of blocks, with the lower edges of said formboards overhanging the previously moulded course of blocks, wherein apparatus further includes a preformed insulation insert which is adapted to be located into said blocks in a course during forming of the course, such that a wall formed by said multiple courses of blocks is continuous.  
   
   
       2 . A moulding apparatus according to  claim 1 , wherein the insulation insert is formed from a sheet of insulation material with a protruding stem which is adapted to fit into space vacated by partition when the partition is removed.  
   
   
       3 . A moulding apparatus according to  claim 1 , wherein the partitions include a partition body which is substantially wider in the center than at the either of the vertical edges and is slightly wider at the upper edge than the lower edge with curved outer surfaces.  
   
   
       4 . A moulding apparatus according to  claim 2 , wherein surfaces of the insulation insert including the sheet and the stem thereof are adapted to correspond to the curved surfaces of the partition.  
   
   
       5 . A moulding apparatus according to  claim 4 , wherein the partitions are tapered, and therefore, the insulation insert has corresponding tapered surfaces.  
   
   
       6 . A moulding apparatus according to  claim 1 , wherein brick tie means are adapted to be associated with the insulation insert.  
   
   
       7 . A moulding apparatus including a plurality of vertical formboards in a pair of opposed rows, each said formboard being connected to an adjacent said formboard by clamping means and spaced apart from opposed said formboard by one of a plurality of partitions, each said partition being attached to both said opposed rows thereby spacing the opposed rows apart and forming a mould between a pair of adjacent partitions and a pair of opposed formboards, said partitioning apparatus being useable to cast blocks in a course by filling the moulds with a hardenable material, said partitioning apparatus being positionable above the previously moulded course of blocks, with the lower edges of said formboards overhanging the previously moulded course of blocks, wherein the clamping means is disposed such as to clamp the vertical edges of two adjacent formboards with one of the vertical edges of the partition body, with the adjacent formboards being substantially end to end and said partition at substantially right angles line of said formboards, wherein said formboards have recesses adjacent said internal edges where an internal portion of clamp means is adapted to be received.  
   
   
       8 . A moulding apparatus according to  claim 7 , wherein external portion of the clamp means has protrusions which are adapted to be received within slots on outside of the formboards.  
   
   
       9 . A moulding apparatus according to  claim 8 , wherein the width of the internal portion of the clamp means is increased such as to change the orientation of the outer formboard line to thereby form a curved surface for the wall.  
   
   
       10 . A moulding apparatus according to  claim 9 , wherein the clamping means is adapted to join adjacent formboards together without the use of a partition, to provide a larger block size using modular sized formboards.  
   
   
       11 . A moulding apparatus including a plurality of vertical formboards in a pair of opposed rows, each said formboard being connected to an adjacent said formboard by clamping means and spaced apart from opposed said formboard by at least one space means, each said spacer means being attached to both said opposed rows thereby spacing the opposed rows apart and forming a formwork for a monolithic wall, wherein the clamping means is disposed such as to clamp the vertical edges of two adjacent formboards being substantially end to end and, wherein said formboards have recesses adjacent said internal edges where an internal portion of clamp means is adapted to be received.  
   
   
       12 . A moulding apparatus according to  claim 11 , wherein an external portion of the clamping means is adapted to overlap the upper and lower rows of formboards.
