EARTHQUAKE RESISTANT REINFORCING METHOD FOR EXISTING BUILDING BY RC EARTHQUAKE RESISTANT WALL

摘要

PROBLEM TO BE SOLVED: To improve earthquake resistance by adhering a channel steel-made frame material to the inner face of a column beam frame in a manner the channel shape faces inward, and expanding an earthquake resistant wall having an anchor bar projecting from a channel bottom.;SOLUTION: The channel shape of a remarkably large channel steel-made steel-frame material 4 as compared with the wall thickness of an RC earthquake resistant wall 3 is arranged in substantially the same length as the inner size of a column 1 or a beam 2 on a frame inner face comprising the column 1 and the beam 2 in a manner facing inward. Next, the frame 4 is adhered to the column and beam frame by an adhesive 5, and a wall 3 projecting an anchor bar is extended inward from the channel bottom of the frame 4. In addition, in accordance with request, the frame 4 is adhered to be arranged on the four circumferences of the wall 3 along the inner face of the upper and lower beams 2 and the right and left columns 1 or adhered to be arranged along the inner face of the upper and lower beams 2. Furthermore, if the frame 4 is a material having a sufficient wide flat face on the firm adhesion of the column 1 and the beam 2 without being limited to the channel type steel material, it may be a flat steel plate, a T-shape steel, a hat-shaped steel or the like. Thereby earthquake resistance can be improved, and since noise and vibration are low, construction can be performed as one sits.;COPYRIGHT: (C)2001,JPO
