The assembly and dismantlement construction method null of the multilayer building which uses the self ascent and descent type jacking-up

摘要

PURPOSE:To simplify operations by a method in which a multilayer building having columns and floor panels is constructed in order or disintegrated by the elevating operation of parts using a self-elevating jack device and also by operation on an operating floor panel. CONSTITUTION:After constructing structural parts below the floor panel 6 of an operation floor, columns 7 are erected on the panels 6 and a self-elevating jack device 8 is set on them. The uppermost n-th floor panel 9 is formed below the device 8, the columns 7 are additionally connected, and the floor 9 is lifted up by the device 8 and a floor panel is hung down by a hanger 16 from the downside of the panel 9 to form a (n-1)th floor panel 17 beneath the panel 9. The same operations are made thereafter to form the floor panel 21 of the second floor, and the floor panels of each floor are connected to the columns 7. The jack device 8 and the temporary building materials are removed. In disintegrating operation, the operations are made conversely. The fabricating and disintegrating operations can thus be simplified.
