HYBRID STRUCTURE FLOOR SYSTEM IN BUILDING

摘要

PROBLEM TO BE SOLVED: To provide a hybrid structure floor system in a building capable of solving such a problem that a steel framed joist becomes a heavy structure because a structural body (an underground beam or the like) of a building body is required separately from a steel framed joist structure floor in the case a floor having high load resistance is constructed by a conventional method in a clean room or the like, there is a fault costing a great deal because of using an expensive weight resistance type free access floor, at the same time, it is difficult to ensure a large effective underfloor space and that the floor height of a building is greatly raised.;SOLUTION: A plurality of underground beams 1 (or girders) as the structural body of the building are projected in parallel with each other, a plurality of concrete molded plates 2 are erected between the underground beams or girders, at the same time, a concrete 3 is placed thereon to form a floor 4, and the hybrid structure floor system constituting an access section 7 between an upper space 6 and a lower space 5 is provided to part of the floor.;COPYRIGHT: (C)2004,JPO
