CONSTRUCTION SYSTEM AND METHOD FOR MULTI-FLOOR BUILDINGS

摘要

A multi-floor building construction system and method for progressively constructing floors on the building, as the occupational need to do so arises and while some floors can be occupied, is described. A permanent roof structure is displaceably supported over at least an occupational first floor space constructed on the foundation. Extensible load support elements are secured in the roof structure and adapted to rest upon the load-bearing means to support a total load of the permanent roof structure. The extensible load support means are operated in synchronization. Extensible occupants elevators service the occupational floor space. A wall enclosure is secured inside and about the permanent roof structure. Hoisting devices are secured inside the permanent roof structure and adapted to lift construction sub-assemblies fabricated in a construction zone created by lifting the permanent roof structure over an uppermost floor of the building where a further occupational floor space is to be constructed under the permanent roof structure with the permanent roof structure held elevated from the uppermost floor by the extensible load support means. Construction materials are transported by a dedicated and enclosed vertical transportation system and there are therefore no exterior cranes. Electricity and ventilation are supplied in an extendable way whereby to permit occupation and construction simultaneously. The invention also relates to a method of progressively constructing a multi-floor building, floor-by-floor, as the occupational need to do so arises upon the pre-sale of at least portions of a further occupational floor space to obtain the financing to construct the further occupational floor space.
