双塔高位连体混凝土结构施工钢平台施工技术

Construction Technology of Steel Platform for Concrete Structure Construction Between Two Towers in High-sky

双塔高位连体混凝土结构施工条件差,大面积高空支模难度大。为提供良好的施工作业环境,在双塔建筑之间搭设施工钢平台。钢平台由x向桁架、y向桁架、外挑三角桁架及次梁组成。以实际工程为例,介绍高空施工钢平台的制作、分解式安装和拆卸过程。由于高空作业风险较大,通过设置多道安全防线,确保顺利、安全地完成整个施工平台的安拆工作。

The construction circumstance of concrete structure between two towers in high-sky is bad,and large areas supporting formwork in high-sky is difficult.Steel platform is set up between two towers to provide good construction circumstance.The steel platform composed of x-direction and y-direction trusses,cantilever triangle truss and second beams.The fabrication,installation by means of decomposed and dismantle process of steel platform in high-sky are introduced based on a practical project.Because of greater risk in high-sky working,the steel platform is installed and dismantled successfully by adopting many safe prevention measures.
