Connecting structure of frame column and reinforced concrete beam and construction method of connecting structure
The invention discloses a frame column and reinforced concrete beam connecting structure and a construction method thereof. The frame column and reinforced concrete beam connecting structure comprises a frame column and a reinforced concrete beam; a steel bar anchoring box is arranged on the side, close to the reinforced concrete beam, of the frame column and corresponds to the upper portion of the reinforced concrete beam. The tops of the steel bar anchoring boxes are provided with sockets; the ends, close to the frame columns, of the beam upper longitudinal bars are bent downwards by 90 degrees to form inserting sections. The insertion section is inserted into the steel bar anchoring box, and the insertion depth is not smaller than 8 times of the nominal diameter of the upper longitudinal bar of the beam; the steel bar anchoring box is filled with high-strength ductile mortar; connecting pieces are arranged on the side surfaces, close to one sides of the reinforced concrete beams, of the frame columns and correspond to longitudinal bars at the lower parts of the beams; the beam lower longitudinal bars are fixedly connected with the connecting pieces; the beam concrete is poured on the outer side of the beam steel reinforcement framework. The technical problem that a traditional beam-column joint cannot reduce the construction difficulty and the construction complexity on the premise that the joint internal force transmission reliability, the joint bearing resistance and the joint shear bearing resistance are good is solved.
一种框架柱与钢筋混凝土梁的连接结构及其施工方法，包括框架柱和钢筋混凝土梁；框架柱靠近钢筋混凝土梁一侧、对应钢筋混凝土梁的上部位置处设有钢筋锚固盒；钢筋锚固盒顶部设有插口；梁上部纵筋靠近框架柱的一端向下弯折90°，形成插接段；插接段插在钢筋锚固盒中，且插入深度不小于8倍的梁上部纵筋的公称直径；钢筋锚固盒中填充有高强延性砂浆；框架柱靠近钢筋混凝土梁一侧的侧面上、对应梁下部纵筋位置处设置有连接件；梁下部纵筋与连接件固定连接；梁混凝土浇筑在梁钢筋骨架的外侧。本发明中解决了传统的梁柱节点无法在满足节点内力传递的可靠性、节点的抗承载能力和节点的抗剪切承载能力良好的前提下降低施工难度和施工复杂性的技术问题。
