Prefabricated concrete construction brick for walls - has cast natural stone facing and recess to retain guide beam

摘要

The rectangular block has a mass of concrete (1) with facing (2) aoplied in the mould. The blocks are joined on non dressed faces by casting C-shaped metal profiles (4) with the outside edges returned so that an H shaped metal profile can be inserted vertically between two abutted profiles (4), pinning them together. A thin groove (8) is also cast into the blocks around all four faces so that a flexible weatherproofing sealing strip can be inserted both between blocks in the same course and between blocks in adjacent courses.
