The invention relates to the technical field of building construction, in particular to a turnover bracket construction method for an internal climbing tower crane, which comprises the following steps of: preparing for construction, checking a welding seam detection report after main materials such as a sleeve embedded part, a bracket, an internal climbing bearing beam and a bolt enter a site, re-checking the size of a main component and the position and the size of a reserved hole, and ensuring the consistency with a design drawing; the bracket has the advantages that the bracket is convenient to disassemble after the tower crane climbs, and the bracket can be recycled. The steel corbel is attached to the shear wall by embedding the sleeve in the concrete shear wall, bolting the steel corbel with the shear wall and bolting the steel corbel with the internal-climbing bearing beam, so that the internal-climbing tower crane corbel can be recycled, the purpose of saving the construction cost can be achieved, the corbel is more convenient and quicker to use, and the construction efficiency is improved. And the problems that when an existing steel corbel is used, the welding amount is large, the welding seam requirement is high, construction safety is not easy to guarantee, and turnover use cannot be achieved are solved.
本发明涉及建筑施工技术领域,尤其为一种内爬塔吊可周转牛腿施工方法,其方法包括如下步骤:施工准备,套管埋件、牛腿、内爬承重梁、螺栓等主要材料进场后检查焊缝检测报告,复核主要构件尺寸及预留孔洞位置、尺寸,保证和设计图纸一致;本发明具有在塔吊爬升后方便拆卸牛腿,实现了牛腿周转使用的优点。通过在混凝土剪力墙内埋设套管,钢牛腿与剪力墙栓接、钢牛腿与内爬承重梁栓接的方式,使得钢牛腿附着于剪力墙上,实现内爬塔吊牛腿的周转使用,从而能够达到节约施工成本的目的,使得牛腿的使用更加方便、快捷,且能够避免重复性的搭拆工作,解决了目前钢牛腿使用时焊接量大,焊缝要求高,施工安全不易保证,且无法周转使用的问题。
