复杂钢结构旋转梯制作施工技术

Production of Construction Technology of the Complicated Steel Spiral Staircase

钢结构旋转楼梯的制作施工一直是钢结构施工的难点,针对某大型复杂钢结构旋转梯进行的制作施工,通过采取专用的旋转梯胎架,确保了旋转梁及旋转梯分段制作及尺寸控制,同时对旋转梯的焊接进行质量控制,满足了设计和施工规范要求,保证了质量和安全,收到了良好的经济和社会效益。

The complicated steel spiral staircase is a difficulty of steel construction.Steel structure for a large and complex for the production of spin ladder construction,ladder by taking special rotating tire rack,ensure that the sub-rotating beams and rotating ladder and size control of the production,while the spin ladder of welding quality control to meet the design and construction specifications to ensure quality and safety,and good economic and social benefits.
