WALL BALUSTRADE REINFORCEMENT METHOD AND REINFORCEMENT STRUCTURE
To perform reinforcement by adding a pulling member to both internal and external sides at a lower end part of a wall balustrade made from concrete and making compressive stress act on the lower end part of the wall balustrade.SOLUTION: Directly under an internal surface of a wall balustrade 1A, a through hole 2a which vertically passes through a concrete slab 2 and through which a belt-like or rope-like reinforcement member 11 is inserted is formed. The reinforcement member 11 is continuously disposed so as to start from a position along the internal surface of the wall balustrade, pass through the through hole, reverse on the underside of the concrete slab 2, and reach a position along an external surface of the wall balustrade. Then, the reinforcement member's both ends are individually fixed on the internal surface and the external surface of the wall balustrade. On the underside of the concrete slab 2, the reinforcement member 11 is wound around a curved surface of a tension block 12 to lock the tension block 12 in the reinforcement member and downward force is applied to the tension block to introduce tension force to the reinforcement member 11. The tension block 12 is fixed by filling a gap between the tension block and the concrete slab with shrinkage-compensating mortar 15.SELECTED DRAWING: Figure 2
【課題】コンクリートからなる壁高欄の下端部における内側及び外側の両面に引張部材を付加するとともに壁高欄の下端部に圧縮応力度を作用させて補強する。【解決手段】壁高欄１の内壁面の直下に、コンクリート床版２を上下方向に貫通して帯状又は綱状の補強部材１１が挿通される貫通孔２ａを形成する。補強部材１１は、壁高欄の内壁面に沿った位置から貫通孔を通過し、コンクリート床版２の下側で反転して壁高欄の外壁面に沿った位置にまで連続するように配置して、両端部は壁高欄の内壁面及び外壁面にそれぞれ固定する。コンクリート床版２の下側では、緊張用ブロック１２が有する曲面に補強部材１１を巻き回して緊張用ブロック１２を補強部材に係止し、緊張用ブロックに下方への力を付与して補強部材１１に緊張力を導入する。緊張用ブロック１２はコンクリート床版との間に無収縮モルタル１５を充填して固定する。【選択図】図２
