Construction method for existing structural floor slab and newly-built steel column and connecting joint of existing structural floor slab and newly-built steel column
The invention discloses a construction method for an existing structural floor slab and a newly-built steel column and a connecting joint of the existing structural floor slab and the newly-built steel column. The construction method comprises the following steps that S1, concrete of the existing structural floor slab is broken, middle reinforcing steel bars are cut off, and reinforcing steel bars on the edge of a beam-slab support are reserved; s2, a connecting assembly is welded to the newly-built steel column in advance, and then the newly-built steel column is hoisted to the installation position of the structural floor slab; s3, after the newly-built steel column is hoisted, an elastic piece is installed close to the connecting assembly and attached to the newly-built steel column; s4, newly-built floor slab reinforcing steel bars are installed, the newly-built floor slab reinforcing steel bars are connected with the reinforcing steel bars reserved in the step S1, the newly-built floor slab reinforcing steel bars broken at the collision positions stretch into the connecting assemblies, and then studs are welded to the connecting assemblies; s5, micro-expansive concrete at least one grade higher than the existing structural floor slab is poured and maintained for at least 14 days; installation of the newly-built steel column can be scientifically guided, and the service life of the newly-built steel column and the service life of the reconstructed structural floor slab can be prolonged.
本发明公开了一种既有结构楼板与新建钢柱施工方法及其连接节点，施工方法包括以下步骤：S1、破除既有结构楼板的混凝土，切除中部钢筋，且预留梁板支座边的钢筋；S2、提前在新建钢柱上焊接连接组件，再将新建钢柱吊装到结构楼板的安装位置；S3、新建钢柱吊装完成后，在连接组件附近，贴着新建钢柱安装弹性件；S4、安装新建楼板钢筋，使新建楼板钢筋与S1步骤中预留的钢筋连接，且使碰撞位置处断开的新建楼板钢筋伸入到连接组件中，之后，再在连接组件上焊接上栓钉；S5、浇筑比既有结构楼板至少高一等级的微膨胀混凝土，并养护至少14天；本发明可以科学指导新建钢柱的安装，有利于提高新建钢柱与改造后结构楼板的使用寿命。
