Construction process of large span complex arch roof
The invention discloses a construction process of a large span complex arch roof. The construction process comprises the following steps of (1) erecting a bed-jig right below a landing arch mounting position; (2) hoisting a first arch and a second arch in the middle; (3) hoisting a first truss column of shaft 1 and shaft 18 by a crawler crane; (4) hoisting the first truss column of a shaft 2 withthe crawler crane continuously, additionally arranging a hawser immediately for stabilization after the first truss rack is in position, mounting a corresponding partial wall beam to form a stable structure, wherein the structural safety is ensured; (5) hoisting a second truss column of the shaft 1 continuously, and mounting the corresponding partial truss beam immediately after the truss column is mounted to form a stable structure; (6) hoisting the second truss column of the shaft 2 similarly as well as corresponding main and secondary truss beams, and mounting the corresponding partial wallbeam immediately to form a stable structure; (7) continuously mounting the truss column and the truss beam according to the steps; and (8) finally, finishing all mounting work. By adopting the process, within a limited construction period, the construction quality and the construction safety are ensured effectively, a designed demand is fully met, and the construction process has obvious social and environmental-friendly benefits.
本发明公开了一种大跨度复杂拱架屋盖施工工艺，包括下列步骤：（一）在落地拱架安装位置正下方搭设胎架；（二）吊装中间的第1、2段拱架。（三）履带吊吊装1轴、18轴的第1段桁架柱。（四）继续用履带吊吊装2轴第1段桁架柱，就位后立即增设缆风绳进行稳固，并安装相应的部分墙梁，形成稳定结构，保证结构安全。（五）继续用吊装1轴的第2段桁架柱，桁架柱安装好后立即安装相应的部分桁架梁，形成稳定结构。（六）同样用吊装2轴的第2段桁架柱，及相应的主、次桁架梁，并立即安装相应的部分墙梁，形成稳定结构。（七）按照上述步骤，继续安装桁架柱、桁架梁。（八）最终完成所有的安装工作。采用本工艺，在有限的工期内，有效的保证了施工质量和施工安全，完全达到了设计要求，具有明显的社会和环保效益。
