PROBLEM TO BE SOLVED: To provide a reinforced structure of a masonry wall capable of carrying out effective reinforcement for the whole stone masonry without being required for any working space on the front side.
SOLUTION: The reinforced structure is applied to the masonry wall 16 piling up in the vertical direction so as to adjoin masonry blocks 14 to one another by making a backing cobble stone layer 12 intervene in the front of an inclined bedrock 10 as a cut section, and it includes an upper part and leg concrete boards 18 and 20, a pair of holding plates 22, a plurality of stay piles 24 and a footing pile 26 and a screen material 28. The concrete board 18 is located on the lower end side of the masonry wall 16 and extended in the longitudinal direction. Each holding plate 22 is extended in the vertical direction of the masonry wall 16, and both up and down ends are fixed to the concrete board 18 and the concrete board 20, respectively. The stay pile 24 is driven in the bedrock 10 on the back side of the backing cobble stone layer 12. The footing pile 26 is driven in the bedrock 10 on the front side of the masonry wall 16.
