Steel bar avoidance fabricated beam column reinforced L-shaped joint
The invention relates to a steel bar avoidance fabricated beam column reinforced L-shaped joint, and belongs to the field of fabricated beam columns. The outer sides of a concrete composite beam a anda concrete composite beam b are consistent with the two outer sides of a prefabricated concrete column, and the concrete composite beam a and the concrete composite beam b are correspondingly locatedbetween a corner straight steel bar and a transposition avoidance bending steel bar of the prefabricated concrete column; and the overhanging parts of a beam bottom avoidance vertical bending longitudinal bar and a beam bottom avoidance inclined bending longitudinal bar are located above the overhanging parts of a beam bottom avoidance horizontal bending longitudinal bar and a beam bottom straight longitudinal bar. The steel bar avoidance fabricated beam column reinforced L-shaped joint has the advantages and effects that a large number of joint steel bars can be reasonably avoided in the construction process, and on the premise of ensuring the reasonable avoidance, shear keys in all directions can be reasonably arranged, the bearing capacity of the joint is significantly improved, and especially the shear resistance of the joint is significantly improved. The characteristics that joint construction is convenient, the construction speed is high, and the economic effect is good are achieved. Moreover, the components are easy to produce, and the arrangements of various steel bar avoidance and the shear keys do not affect the factory production.
本发明涉及一种钢筋避让装配式梁柱加强L形节点，属于装配式梁柱领域。混凝土叠合梁a、混凝土叠合梁b的外侧与预制混凝土柱的两个外侧边一致，且均分别位于预制混凝土柱的角部直钢筋和换位避让弯折钢筋之间；梁底避让竖向弯折纵筋、梁底避让斜向弯折纵筋外伸的部分位于梁底避让水平弯折纵筋和梁底直纵筋外伸部分的上面。本发明的优点效果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，且构件便于生产，各种钢筋避让和剪力键设置，不影响工厂生产。
