Form-removal-free construction method for cantilever end of fabricated floor support plate
The invention relates to the technical field of construction of fabricated buildings, in particular to a formwork-removal-free construction method for a cantilever end of a fabricated floor support plate, which at least comprises the step of manufacturing a main body structure by adopting a prefabrication method; the outer side of the PC beam on the periphery of the building is machined into a triangle through three pieces of angle steel so as to control the elevation and serve as a support; an L-shaped riffled plate is used as a permanent formwork to be welded and fixed to horizontal angle steel and PC beam reserved steel bars; and the riffled plate is derusted and coated with anti-rust paint. According to the construction method of the fabricated floor support plate overhanging end, the workload of high-altitude formwork erecting can be remarkably reduced, so that the risk of high-altitude operation can be reduced, excessive use and waste of formwork materials are avoided, meanwhile, the construction procedures are reduced, and the construction progress can be accelerated while the construction quality can be guaranteed; and in addition, the structure appearance quality can be improved finally, and painting work is not needed.
本发明涉及装配式建筑的施工技术领域，具体是一种装配式楼承板外挑端的免拆模施工方法，其至少包括采用预制法进行主体结构制作的步骤；建筑外围PC梁的外侧以三根角钢加工成三角形以控制标高及作为支撑的步骤；以“L”型花纹钢板作为永久模板，与水平方向角钢及PC梁预留钢筋焊接固定的步骤；将花纹钢板除锈并涂抹防锈漆的步骤。本发明所提出的装配式楼承板外挑端的施工方法，能够显著减少高空支模的作业量，从而能够降低高空作业风险，避免模板材料的过度使用和浪费，同时，还减少了施工工序，从而在能够保证施工质量的同时，还能加快施工进度；并且最终能够提高结构表观质量，无需再做粉刷工作。
