Reinforcing steel bar avoiding assembly type beam column reinforcing T-shaped joint
The invention relates to a reinforcing steel bar avoiding assembly type beam column reinforcing T-shaped joint, and belongs to a novel assembly type concrete beam column joint of a building structure.The reinforcing steel bar avoiding assembly type beam column reinforcing T-shaped joint is characterized in that when the number of beam bottom reinforcing steel bars is an even number, half of the beam bottom reinforcing steel bars of a precast concrete superposed beam are horizontally bent twice, and the other half of the beam bottom reinforcing steel bars are not bent; when the number of the beam bottom reinforcing steel bars is odd, the difference between the number of the beam bottom reinforcing steel bars bent twice and the number of the unbent beam bottom reinforcing steel bars is 1; and beam bottom avoiding vertical bent reinforcing steel bars are horizontally located on the upper portions of beam bottom avoiding horizontal bent reinforcing steel bars after being bent and are perpendicular to the beam bottom avoiding horizontal bent reinforcing steel bars. The joint has the effects and advantages that a large number of joint reinforcing steel bars can be reasonably avoided inthe construction process, on the premise that reasonable avoiding is guaranteed, shear keys in all directions are reasonably arranged, the bearing capacity of the joint is remarkably improved, and particularly the shear capacity of the joint is remarkably improved. Joint construction is convenient, the construction speed is high, and the economic effect is good.
一种钢筋避让装配式梁柱加强T形节点，属于建筑结构新型装配式混凝土梁柱节点，当梁底纵筋数量为偶数时，预制混凝土叠合梁的一半梁底纵筋水平弯折两次；另一半梁底纵筋均不弯折；奇数时，弯折两次的梁底纵筋和未弯折梁底纵筋数量相差1根；梁底避让竖向弯折纵筋弯折后水平位于梁底避让水平弯折纵筋的上部且垂直于梁底避让水平弯折纵筋。本发明的效果和优点是能够使大量的节点钢筋在施工的过程中合理避让，且在保证合理避让的前提下，合理设置各个方向的剪力键，节点承载力显著提高，尤其是显著提高了节点的抗剪能力。节点施工方便、施工速度快、经济效果好等特点。
