WALL BALUSTRADE REINFORCEMENT METHOD AND REINFORCEMENT STRUCTURE
To perform reinforcement by making vertical compressive stress act on a lower end part of a wall balustrade made from concrete.SOLUTION: A tension material insertion hole 12 reaching the inside of a wall balustrade 1 is drilled upward from an underside of a concrete slab 2, and an anchorage part formation hole 15 communicating with an upper part of the tension material insertion hole is cut from a side surface of the wall balustrade. A tension material 11 is inserted into the tension material insertion hole 12 and the tension material insertion hole is filled with shrinkage-compensating mortar 14 from the anchorage part formation hole, to anchor an upper end part of the tension material to the wall balustrade. A lower end part of the tension material is tensed by the underside of the concrete slab and the tension material in a state in which tension force is introduced is anchored to the concrete slab and thickness increased concrete 13 placed so as to be integrated with the concrete slab. The thickness increased concrete 13 is placed so as to cover a lower part of an external surface of the wall balustrade from the underside of the concrete slab and reinforces the concrete slab's tip and the wall balustrade's lower part integrally with the concrete slab and the wall balustrade.SELECTED DRAWING: Figure 2
【課題】コンクリートからなる壁高欄の下端部に上下方向の圧縮応力度を作用させて補強する。【解決手段】コンクリート床版２の下側から上方へ壁高欄１内に至る緊張材挿通孔１２を穿設するとともに、壁高欄の側面から緊張材挿通孔の上部に連通する定着部形成穴１５を切削する。緊張材挿通孔１２に緊張材１１を挿通するとともに、定着部形成穴から無収縮モルタル１４を緊張材挿通孔に充填し、緊張材の上端部を壁高欄に定着する。コンクリート床版の下側で緊張材の下端部を緊張し、緊張力を導入した状態で緊張材をコンクリート床版及びコンクリート床版と一体となるように打設された増厚コンクリート１３に定着する。増厚コンクリート１３は、コンクリート床版の下側から壁高欄の外壁面の下部を覆うように打設されたものとし、コンクリート床版及び壁高欄と一体となってコンクリート床版の先端部及び壁高欄の下部を補強する。【選択図】図２
