Roof truss hoisting method
The invention discloses a roof truss hoisting method. The roof truss hoisting method is conducted according to the following steps that (1) in a site, n roof trusses are first assembled to form a rooftruss system, and n is equal to or greater than 2; (2) at least two carrying poles playing a supporting role are welded at the bottom of a lower chord of the roof truss system in the length directionof the roof truss system; (3) four hoisting points are selected on an upper chord of the roof truss system, and then the roof truss system is hoisted by a crane to the position of a pre-embedded plate at the top of a prefabricated column to complete the installation; and (4) the roof truss system and the carrying poles playing the supporting role are split, and the carrying poles are hoisted to the ground by the crane. The roof truss hoisting method does not require workers to work high above the ground, the hoisting stability of the multiple roof trusses is improved by welding the carrying poles playing the supporting role, and thus the roof truss hoisting method is simple, convenient and high in efficiency and safety.
本发明公开了一种屋架吊装方法，按如下步骤进行：1)在场地内先将n榀屋架拼装完成，组成屋架系统，其中，n≥2；2)在屋架系统下弦底部沿屋架系统长度方向焊接至少两个起支撑作用的扁担；3)在屋架系统上弦选取四个吊点，然后用吊车将屋架系统吊装至预制柱柱顶预埋板的位置完成安装；4)拆分屋架系统与起支撑作用的扁担，用吊车将扁担吊落至地面。本发明的屋架吊装方法不需要工人高空作业，通过焊接起支撑作用扁担增加多榀屋架吊装稳定性，因此简单、方便、效率高，安全性高。
