EARTHQUAKE-RESISTING WALL STRUCTURE IN EXISTING REINFORCED CONCRETE-CONSTRUCTED BUILDING AND STEEL ENCASED REINFORCED CONCRETE-CONSTRUCTED BUILDING

摘要

PROBLEM TO BE SOLVED: To provide earthquake-resisting wall structure capable of carrying out earthquake-resistant reinforcing execution while being worked in an existing reinforced concrete-constructed building and a steel encased reinforced concrete- constructed building. ;SOLUTION: A plurality of lightweight C-steel blocks 14 cut in humanly portable length are stacked in the vertical direction so that webs 14a coincide on the flanges 14b of the blocks 14 in a manner that the webs 14a of the blocks 14 are formed in wall plate surfaces, and arrayed in the direction of the axis of materials. The web sections of the lightweight C-steel blocks 14 are clamped to the web section of a holding frame 17, in which the flange surfaces of CT steel 16 are extended and bonded and joined 21 onto the inner circumferential surface of a beam-column frame, by fasteners 15 in a steel-plate wall 13, in which each flange 14b is fastened by the fasteners 15 in the upper and lower lightweight C-steel blocks 14 and the webs 14a of the lightweight C-steel blocks 14 are bonded with flanges 16a as assisting vertical members in CT steel 16 by the fasteners 15 in connection in the direction of the axis of materials.;COPYRIGHT: (C)1999,JPO
