Construction method of back-pull large-cantilever steel structure roof
The invention relates to the technical field of building construction, and discloses a back-pull large-cantilever steel structure roof construction method which comprises the following construction steps: fixedly mounting a core tube on a concrete stand; the pipe truss is fixedly installed at the top end of the core tube; an outer side cantilever is fixedly installed on the side, close to the outside, of the pipe truss, and the side, away from the pipe truss, of the outer side cantilever is pulled in the direction of the concrete stand; the first temporary support is installed in the venue; an inner side cantilever is fixedly installed on the side, close to the field, of the pipe truss, and the end, away from the pipe truss, of the inner side cantilever abuts against the first temporary support; and after the inner side cantilever is installed, the first temporary support is detached and removed. The outer overhang can be pulled, the weight needing to be borne by the core tube is shared, the roof can be supported by using a small number of core tubes, and the effect that the installation number of the core tubes is reduced while the roof is stably installed is achieved.
本申请涉及建筑施工技术领域，公开了一种背拉大悬挑钢结构屋盖施工方法，以下施工步骤：将核心筒固定安装在混凝土看台上；将管桁架固定安装在核心筒的顶端；将外侧悬挑固定安装在管桁架靠近场外的一侧，朝混凝土看台方向对外侧悬挑远离管桁架的一侧进行牵拉；将第一临时支撑安装在场馆内；将内侧悬挑固定安装在管桁架靠近场内的一侧，且内侧悬挑远离管桁架的一端抵接在第一临时支撑上；待内侧悬挑完成安装后，将第一临时支撑拆卸撤销。本申请具有能够通过对外侧悬挑进行牵拉，分担了核心筒所需承受的重量，使用少量核心筒也能够对屋盖进行支撑，达到确保屋盖安装稳定的同时减少核心筒的安装数量的效果。
