Connecting joint structure of existing support column and newly-added beam and construction method of connecting joint structure
The invention discloses a connection node structure of an existing support column and a newly-added beam and a construction method of the connection node structure. The shear resistance of the newly-added beam is improved through a shear resistance structure, an anchor plate of the shear resistance structure is connected with the side face of the existing support column, and a rear expanded-base inverted-cone-shaped anchor bolt is adopted when the anchor plate is connected with the existing support column; a structural adhesive is poured into a gap between the anchor plate and the existing support column, a steel bar structure of the newly-added beam is bound to the periphery of the section steel rib of the shear-resistant structure, it is guaranteed that two stirrups exist within the length range of the section steel rib, and then newly-added beam concrete is poured. The connecting joint structure of the existing support column and the newly-added beam is simple in structure and convenient to construct and install, bending rigidity cannot be increased, a shear-resistant structure is safe and reliable in bonding, and the connecting joint structure has large shear-resistant strength. The problem that the shear strength of a newly-added connecting beam is insufficient due to the fact that the structure of a beam column joint is complex and the requirement for normal distribution of reinforcing steel bars of the newly-added connecting beam cannot be met when the connecting beam is newly added between existing support wall columns is solved.
本发明公开了一种既有支座柱与新增梁的连接节点构造及其施工方法，通过抗剪结构增加新增梁的抗剪能力，抗剪结构的锚板与既有支座柱的侧面连接，锚板与既有支座柱连接时采用后扩底倒锥形锚栓，并在锚板与既有支座柱间隙中灌注结构胶，抗剪结构的型钢钢骨的外周绑扎新增梁的钢筋结构，型钢钢骨的长度范围内保证存在两只箍筋，随后浇筑新增梁混凝土。本发明的既有支座柱与新增梁的连接节点构造的结构简单，施工安装方便，不会增加抗弯刚度，抗剪结构粘结安全可靠，具有较大的抗剪强度。本发明解决了在既有支座墙柱之间新增连接梁，由于梁柱节点处构造复杂，无法满足新增连接梁的钢筋正常分布需求，导致新增连接梁的抗剪强度不足的问题。
