Cantilever steel structure and construction method thereof

FAN SHIJU / FAN SHIXIN / YUAN TAO / XU LI

The invention relates to the technical field of steel structures, and particularly relates to a cantilever steel structure and a construction method thereof. The cantilever steel structure comprises atop beam and angle steel, wherein the angle steel is arranged at the end of the top beam, and the top beam is perpendicular to the groove surface of the angle steel; a fixed lining plate is arrangedat the top of the angle steel, and a horizontal steel beam is arranged on the back side of the angle steel corresponding to the lining plate; and when the outer wall surface of a building is locally repaired, the effective utilization rate of rebuilding a cantilever steel structure platform is extremely low, extra workload is consumed, and then the application environment of the cantilever steel structure is limited. Therefore, the lining plate fixed to the angle steel is matched with the top beam for adjusting the height position, a concave structure formed between the lining plate and the top beam is fixed to a protruding structure of the outer vertical face of the building, then a construction platform is formed on the angle steel through the steel beam, the limitation of building the construction platform from the ground is overcome, the construction environment of operators is optimized, and therefore the application range of the cantilever steel structure is widened.

本发明涉及钢结构技术领域，具体涉及一种悬挑钢结构及其悬挑钢结构施工方法，包括顶梁和角钢；所述顶梁的端部设有角钢，顶梁垂直于角钢的槽部表面；所述角钢的顶部设有固定的衬板，衬板对应的角钢背侧设有水平的钢梁；由于对建筑物外墙面进行局部的修缮作业时，重新搭建悬挑钢结构平台的有效利用率极低，并耗费了额外的工作量，进而限制了悬挑钢结构的应用环境；故此，本发明通过设置在角钢上固定的衬板，与调节高度位置的顶梁相配合，使其间形成的凹形结构固定在建筑物外立面的凸起结构上，继而通过钢梁在角钢上构成了施工平台，解决了施工平台从地面搭建的局限性，并优化了作业人员的施工环境，从而提升了悬挑钢结构的适用性范围。
