Hydraulic structure deformation joint
A hydraulic structure deformation joint comprises concrete beams, plates, connecting steel bars and concrete supporting columns, a first deformation joint is arranged between every two adjacent concrete beams, each concrete beam comprises a lower supporting face located on the vertical lower portion, and a margin hole is formed in the side, close to the corresponding first deformation joint, of each lower supporting face. The diameter of the allowance hole is larger than that of the connecting steel bar, the concrete supporting column is arranged on the lower supporting face, a second deformation joint is arranged between the concrete supporting column and the lower supporting face, the connecting steel bar comprises a head end and a tail end, the head end is embedded in the concrete beam and penetrates out through the allowance hole, and the penetrating tail end is embedded in the concrete column. When the supporting column moves slightly relative to the beam in the horizontal direction, the original connecting reinforcing steel bar is easily cut off due to staggering of the adjacent end faces of the beam and the supporting column, and compared with the direct shearing force effect, the allowance hole scheme can remarkably improve the durability of the connecting reinforcing steel bar.
一种水工建筑物变形缝，所述水工建筑物包括混凝土梁、板、衔接钢筋及混凝土支撑柱，相邻的两组混凝土梁之间设有第一变形缝，所述混凝土梁包括位于竖直下方的下支撑面，该下支撑面靠近第一变形缝的一侧设有余量孔，所述余量孔直径大于衔接钢筋直径，所述混凝土支撑柱设置于下支撑面，该混凝土支撑柱与下支撑面之间设有第二变形缝，所述衔接钢筋包括首端及尾端，该首端预埋于混凝土梁内，并通过余量孔穿出，穿出的尾端预埋于混凝土柱内。当支撑柱相对梁水平方向小幅度移动时，原本衔接钢筋因为梁、支撑柱相邻端面的交错而易被剪断，相比直接受到剪力作用，本发明的余量孔方案，能够显著提升衔接钢筋耐久度。
