Construction method of nuclear power station portal frame transfer platform
The invention discloses a construction method of a nuclear power station portal frame transfer platform, and relates to the technical field of nuclear power station steel structure engineering construction, and the construction method comprises the following steps: firstly, assembling the transfer platform on site according to the sequence of assembling buttress arrangement, axis pay-off, component in-place, temporary bolt installation, overall size inspection and adjustment, and high-strength bolt dark rotation and acceptance inspection; carrying out overall acceptance inspection on the assembled transfer platform; then the transfer platform is installed according to the sequence of installation of transfer platform modules, installation of connecting components between the boundary beams and the heavy rail beams and between the boundary beams and the lower platform beams, installation of working platform guardrails at the elevation positions and laying of steel plates; and finally, an A-shaped tubular supporting piece is installed on the lower portion of the transfer platform. The stability and the safety in the installation process are improved, the construction difficulty is reduced, the installation quality is improved, a certain number of temporary bolts penetrate into the platform when installation nodes are installed on the platform, and the effect of better controlling the eccentricity of the transfer platform when the transfer platform is installed is achieved.
本发明公开了一种核电站龙门架转运平台的施工方法，涉及核电站钢结构工程建造施工技术领域，首先按照拼装支墩布置、轴线放线、构件就位、安装临时螺栓、整体尺寸检查及调整、高强度螺栓暗转及验收的顺序现场拼装转运平台；再对拼装之后的转运平台进行整体验收；再按照转运平台模块安装、边梁与重轨梁和下平台梁间连接构件的安装、标高处工作平台护栏的安装、钢板铺设的顺序安装转运平台；最后在转运平台下部安装A型管状支撑件。提高了安装过程中的稳定性和安全性，降低了施工难度，提高了安装质量，平台安装各安装节点时先穿入一定数量的临时螺栓，对转运平台安装时起到对其偏心有更好的控制的效果。
