Installation and construction method of daylighting roof steel beam
The invention relates to the technical field of daylighting roof construction, in particular to an installation construction method of a daylighting roof steel beam, which comprises the following steps of: pre-embedding a plurality of rear embedded parts at two ends of a roof along the sliding direction, paving channel steel as a steel rail at a position needing to slide, fixing the channel steel and the rear embedded parts by welding, hoisting the steel beam to the roof and assembling, the steel beams are hoisted to the roof in three sections through a crane, and the steel beams are assembled into a main steel beam spanning the roof. For daylighting roof steel beam installation, a large-span main steel beam is firstly lifted to a roof in a sectional mode and then assembled into a whole, the hoisting difficulty in a narrow space is reduced, meanwhile, when the main steel beam is installed, the single main steel beam is temporarily reinforced through the supporting arms after being hoisted in place, large vertical displacement cannot occur, and the installation efficiency is improved. The two adjacent main steel beams are connected into a whole through the secondary beams and the I-shaped beams, a flat first sliding body is formed, the integrity of the steel beams is improved, and displacement deformation in the sliding process is reduced.
本发明涉及采光顶施工技术领域，具体涉及一种采光顶钢梁的安装施工方法，在屋面的两端沿滑移方向预埋多个后置预埋件，在需要滑移的位置铺设槽钢作为钢轨，槽钢与后置埋件之间通过焊接固定，将钢梁吊装到屋面并进行组装，钢梁通过吊车分三段吊装到屋面上，并将钢梁进行组装成一个横亘于屋面的主体钢梁。本发明针对采光顶钢梁安装对于大跨度的主体钢梁采取先分段式抬升至屋面再组装成一个整体，降低狭窄空间的吊装难度，同时在主体钢梁安装时，单一的主体钢梁吊装到位后通过支撑臂临时加固，不会发生发生较大竖向位移，并将相邻的两个主体钢梁通过次梁和工形梁连接成一个整体，形成一个平整的第一滑移体，增加钢梁整体性，减少滑移过程中位移变形。
