Novel steel structure bent cap and construction method
The invention discloses a novel steel structure bent cap and a construction scheme, the bent cap comprises a steel hoop, a top plate and a web plate, the top plate is connected with one end of the steel hoop, and the web plate is simultaneously connected with the steel hoop and the top plate; and the bent cap also comprises a first reinforcing rib for enhancing the connection strength between the steel hoop and the top plate and a web reinforcing rib for enhancing the connection strength between the top plate and the web plate. The construction method comprises the following steps that firstly, the construction platform is built; secondly, a bent cap is installed; thirdly, a cushion stone support and a support are installed; and fourthly, the construction platform is dismantled. The vertical bearing force is provided through the steel support formed by the top plate and the first reinforcing rib in combination with the friction force between the steel hoop and an original pier column, anchor bolt connection between a conventional steel bent cap and the original pier column is omitted, drilling in the original pier column is not needed, the original pier column and steel bars in the original pier column are prevented from being damaged, and meanwhile, the situation that the workload is increased due to the fact that the hole site of the steel hoop is difficult to align with the original pier column anchor bolt and the waste hole rate is large is avoided.
本发明公开了一种新型钢结构盖梁及施工方案，盖梁包括钢套箍、顶板和腹板，顶板与所述钢套箍的一端相连，腹板同时连接钢套箍和顶板；还包括用于增强钢套箍与顶板间连接强度的第一加劲肋和用于增强顶板和腹板间连接强度的腹板加强肋。施工方法如下：步骤一：施工平台搭建；步骤二：盖梁安装；步骤三：垫石支座及支座安装；步骤四：施工平台拆除。本发明通过顶板与第一加劲肋构成的钢支撑并结合钢套箍与原墩柱之间的摩擦力提供竖向承载力，取消了常规钢盖梁与原墩柱之间的锚栓连接无需在原墩柱上钻孔，避免了损伤原墩柱及原墩柱内的钢筋提高盖梁施工的质量，同时避免了钢套箍孔位与原墩柱锚栓对位难造成废孔率大而重新开孔增大工作量的情况。
