  • the system combines the advantages of conventionally laid blocks and the advantages of cast walls by confining the shrinkage cracks normally found in cast walls to mortar joints thereby enhancing the appearance of the wall. Shrinkage cracks usually found in cast walls are minimized by virtue of the fact that most of the shrinkage has taken place before the mortar is set.

  • the surfaces of the insulation insert including the sheet and the stem thereof have surfaces adapted to correspond to the curved surfaces of the partition.

  • the formwork system is use to construct walls or like structures by forming blocks or monolithic walls of hardenable material in situ.
  • block forming a foundation is laid onto which the construction is to be positioned and a first course of blocks is formed by setting up the formwork system onto the foundation.
  • the formwork system is then filled with the hardenable material which is allowed to set inside the formwork. Once the material has set to a certain extent the fo ⁇ nwork is removed thus allowing the material to dry and harden into the first course of blocks. After the blocks have hardened the fo ⁇ nwork is then placed on top of the blocks ready for use to form the next course.
  • the material of the "next course of blocks is preferably allowed to form in the gaps left by the removal of the partitions thus increasing tensile strength of the wall. This process is continued until the wall is completed by the use and construction of blocks in situ in the manner described in WO/88/02802.
  • FIG. 1 to 3 One example of a fo ⁇ nwork system which is used to construct the wall is illustrated in Figs. 1 to 3.
  • the system 10 making up the formwork includes a number of formboards 11 which are formed in two opposing rows 12 and 13.

  • the wing nuts 18 are used to clamp the partition 14 and the adj cent formboards 11 together.
  • edges 26 of the partitions 14 are narrow and the fact that the internal portion 21 of the clamps 17 are rebated into the surface of the formboards 11, the joint between each block formed in the formwork system 10 narrow in a similar manner to those of stone walls.
  • This is an improvement over the existing formwork systems.
  • the narrow j oint also has the advantage that when using thin mixes of sand and cement as the material for the blocks, the tendency for the mixture to escape out between wider joints is virtually eliminated.
  • the improved clamping arrangement on either sides 20 and 23 of the formboards 11 also ensures straight true walls.
  • curved walls are able to be constructed using the formwork system of the present invention as the outer portions 25 of the clamps 17 can be reversed and the width of the inner portion 21 can be increased thus allowing one of the rows 13 is curved.

Abstract

Cette invention concerne un appareil de moulage utilisé pour former des blocs de construction. Cet appareil comprend une pluralité de panneaux de coffrage verticaux disposés de manière qu'ils forment une paire de rangées opposées, chacun des panneaux de coffrage étant d'une part fixé à un panneau de coffrage adjacent par des brides de serrage et d'autre part écarté du panneau de coffrage opposé par une cloison, chacune des cloisons étant fixée aux deux rangées opposées, espaçant ainsi les rangées opposées et formant un moule entre une paire de cloisons adjacentes et une paire de panneaux de coffrage opposés. L'appareil de séparation peut être utilisé pour couler des blocs dans une assise selon un procédé consistant à remplir les moules d'un matériau durcissable, l'appareil de séparation pouvant être positionné au-dessus de l'assise de blocs préalablement moulée, les bords inférieurs des panneaux de coffrage surplombant l'assise de blocs préalablement moulée, lequel appareil comprend également un insert d'isolation conçu pour être formé dans ces blocs dans une assise de manière qu'une paroi formée par les multiples assises de blocs soit continue.
