A METHOD AND APPARATUS FOR CONSTRUCTING MULTI-STOREY BUILDINGS

摘要

A method and apparatus for constructing a multi-storey building. A first slab (22) is formed directly on top of a second slab (21). The slab (22) is formed with a plurality of apertures spread about the slab area. A plurality of extendible prop means (10) are positioned in the respective apertures, the head portion (12) of each prop means being connected to the first slab (22), the foot portion (13) of each prop means being supported by a slab below the first slab (22). The prop means (10) is extended such that the first slab (22) is lifted to its desired position. Once in that desired position, the foot portion (13) of each extended prop means is retracted through its respective aperture to engage the upper surface of the first slab (22) and the process is repeated according to the number of storeys required in the building.
