Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an existing column reinforcement structure using a concrete panel having high intensity and toughness.SOLUTION: An existing column reinforcement structure comprises: four concrete panels, which are disposed at a predetermined distance from a surface of an existing column and surround the column so as to become quadrangle in plan view; a connection material, which connects the concrete panels; and a filler, which is charged in a space surrounded by the concrete panels. The concrete panels are laminated in height direction along the column. The connection material comprises a connection plate, which is disposed astride vertically adjacent concrete panels or a lower end connection plate, which is disposed at an end of the concrete panel positioned at an end of the column. The connection plate and the lower end connection plate are formed into substantially L shape in plan view, which comprises a long side part disposed along a rear face of the concrete panel and a short side part connected with the long side part of the other connection plate or the other lower end connection plate disposed on the adjacent orthogonal concrete panels. The concrete panel and the connection material are connected by a bolt-like fixture.SELECTED DRAWING: Figure 1
