Large-span steel beam cantilever beam method installation method for high volley daylighting roof
The invention discloses a large-span steel beam cantilever beam method installation method for a high volley daylighting roof, which is characterized in that a daylighting roof steel beam is characterized by high height, large span and heavy single steel beam, an original cantilever beam butt joint method is adopted, after the steel beam is reasonably segmented, one end of a sub-beam is fixed on a frame beam to form a cantilever form, and the other end of the sub-beam is fixed on the frame beam to form a cantilever beam; according to the construction method, butt welding operation of the steel beams is conducted under the condition that a tower crane does not loosen a hook, the small sections are hoisted firstly, then the large sections are hoisted, construction efficiency and construction safety are guaranteed, the problem that the daylighting roof steel beams are difficult to construct is solved, and compared with an existing construction method that a temporary supporting tower needs to be adopted and a basement needs to be jacked back, the construction cost is reduced. A large amount of construction period and construction material resource cost for tower erection and basement back-jacking are saved, the method creates a precedent for hoisting the overlength and overweight daylighting roof steel beam through a cantilever beam method, and remarkable progress is achieved.
本发明公开了一种高凌空采光顶大跨度钢梁悬挑梁法安装方法，对于采光顶钢梁特点为高度高、跨度大，单根钢梁重，采用了独创的悬挑梁对接法，将钢梁进行合理的分段后，将分梁的一端固定在框架梁上形成悬挑形式，保证塔吊不松钩的情况下进行钢梁的对接焊接操作且先吊装小段再吊装大段，保证施工效率和施工安全性，克服了采光顶钢梁施工难度大的问题，相比于现有施工方法需要采用临时支撑塔架且地下室需要进行回顶的方式，节省了塔架支设和地下室回顶的大量的施工工期和施工物力成本，本方法开创了悬挑梁法吊装超长超重的采光顶钢梁的先河，具有显著的进步。
