PC PC Seismic retrofit PC wall panel for RC frame Seismic retrofit structure of RC frame using PC wall panel and construction method thereof

摘要

A reinforced concrete frame seismic reinforcing structure using a PC wall panel and a PC wall panel for seismic reinforcing of a reinforced concrete frame, and a construction method thereof are disclosed. According to an aspect of the present invention, there is provided a PC wall panel installed in an open space of a reinforced concrete frame composed of a reinforced concrete column and a beam, the reinforced concrete frame having a horizontal portion closely contacting a bottom surface of the open space of the reinforced concrete frame; A vertical part which is in close contact with a side surface of the open space of the reinforced concrete frame; And a right angle portion closely attached to a bottom surface and a side surface of the open space of the reinforced concrete frame and connecting the horizontal portion and the vertical portion to form an L-shape as a whole together with the horizontal portion and the vertical portion, A plurality of horizontal coupling holes for inserting the anchor members are formed in the vertical portion so as to penetrate in the horizontal direction, and a plurality of vertical coupling holes for inserting the anchor members are formed in the horizontal portion and the vertical portion, And a metal frame extending to the inside of the right-angled portion is embedded.
