CONSTRUCTION METHOD FOR BUILDING SKELETON UTILIZING EXISTING FOUNDATION SLAB

摘要

PROBLEM TO BE SOLVED: To shorten a construction period by inserting a steel column through a bored hole in a column in a new building body, and fixing a leg part to a foundation slab of the new building body on an existing foundation slab or a foundation slab of an existing building body. ;SOLUTION: For example, in the case of constructing a foundation beam 6 on the side of a foundation beam 8 of an existing building skeleton, reinforcements of the foundation beam 6 to be connected are disposed in a steel column 2 after fixing the steel column 2, and concrete is placed. In this case, a bored hole in an existing slab 1 is closed with reinforcements and concrete, and the existing slab 1 is used as a slab for a new building skeleton. When an existing foundation beam 8 is unnecessary, it is demolished after construction of the foundation beam 6, or at the time of construction of it, and when it has no hindrance with the new building body, demolition is not required. Work efficiency and safety for new construction are thus improved, temporary construction work is reduced or eliminated to reduce construction cost, and the period from demolition to new construction can be shortened.;COPYRIGHT: (C)1999,JPO
