SPACER ELEMENT FOR BUILDING BLOCKS, CONSTRUCTION UNIT COMPRISING SAID ELEMENT AND METHOD OF SPACING BUILDING BLOCKS

摘要

A spacer element (10) comprises a first engagement portion (12) and a second engagement portion (14). The first engagement portion (12) is arranged to engage in an upper surface of a building block and the second engagement portion (14) is arranged to engage in a lower surface of a second building block. The spacer element (10) comprises two laterally extending arms (16, 18) which project outwardly from the spacer element (10). The laterally extending arms (16, 18) support spacer means in the form of spacer members (20, 22). The spacer members (20, 22) provide an upper contact surface to contact a brick located above and a lower contact surface to contact a lower brick. The spacer element comprises two support members (32, 34). The spacer element (10) provides spacer means which space the next layer of bricks from the lower layer of bricks by a particular distance. As the wall is built vertically upwards further pressure is placed on the support members (32, 34) and the spacer members (20, 22) which may cause the lower edges (30) of the spacer members (20, 22) to fracture or shear. The initial spacing distance may be greater than that required and, therefore, as the mortar sets the mortar will not crack as it contracts since the spacing distance between the building blocks also reduces.
