建筑隔震工程隔震橡胶支座安装施工工艺分析

通过在隔震支座增设X形巨型临时支撑;利用带高度调节螺栓的锚定架等措施精确预埋钢板的定位;对预埋螺栓套筒采用接长锚筋的方式,减少了预埋钢板与支墩(柱)连接处锚筋数量;合理改进下预埋钢板,增设起吊孔、浇筑孔与排气孔,以保证吊装安全和二次浇筑的下支墩(柱)混凝土密实度。通过上述技术改进创新,使隔震支座安装具有质量高、施工快速及较高的经济效益等优点。

建筑工程隔震橡胶支座安装施工分析

建筑工程隔震支座安装施工,主要难点和重点是控制下预埋钢板定位精度和水平精度。通过在下支墩(柱),利用带高度调节螺栓的锚定架等措施精确预埋钢板的定位。合理改进下预埋钢板,增设起吊孔、浇注孔与排气孔,保证吊装安全和下支墩(柱)混凝土密实度。通过采用上述的施工方法,隔震支座安装则将具有质量高、减少施工工期等优点。

Research on Stability Calculation Methods for Grillage Supporting Structure with Pre-stressed Anchor

Aiming at prestressed anchor cable frame in the presence of reinforcement landslide problem, through the selection of test points, the paper study and tested soil pressure, frame internal force and prestress losses under prestressed anchor cable frame beam, reveal the law of internal force distribution, and provides a theory basis for the rational design of prestressed anchor cable in landslide.
