Construction method of multidirectional staggered small-spacing prestressed ribbed beam floor slab
The invention discloses a construction method of a multidirectional staggered small-spacing prestressed ribbed beam floor slab, and relates to the technical field of floor slab construction, a BIM (Building Information Modeling) technology is adopted to carry out modeling analysis on a ribbed beam floor slab system in a deepening design stage, and optimization measures are taken in advance for part of areas where reinforcing steel bars are dense and may be superelevation and nodes are complex; problems possibly encountered during construction are reduced, and the construction progress is accelerated. According to the method, the top elevation of the column cap thick plate area is controlled by laying the steel bars erected in a staggered mode, the situation that the steel bars are stacked too high, and consequently the follow-up finished surface is too high is prevented, and the finished effect of the ribbed beam floor slab is effectively guaranteed. The small dense rib beam lattice formwork system is designed, the formwork system can be applied to parts where gaps between beam lattices are narrow, the beam height is high, and formworks are difficult to erect manually or are difficult to dismantle after pouring, the formwork system is easy to construct and convenient to dismantle, the problem of formwork construction in long and narrow beam lattices can be effectively solved, and therefore the overall construction efficiency is improved.
本发明公开了一种多向交错小间距预应力密肋梁楼板施工方法，涉及楼板施工技术领域领域，在深化设计阶段采用了BIM技术对密肋梁楼板体系进行了建模分析，对于部分钢筋密集可能会超高和节点复杂的区域提前做好了优化措施，减少施工时可能会遇到的问题，加快了施工进度。本发明采用错位搭设的钢筋铺设发明来控制柱帽厚板区的顶标高，防止钢筋堆叠过高从而导致后续完成面超高的情况，有效的保证了密肋梁楼板的完成效果。本发明设计出小型密肋梁格模板体系，该模板体系可应用在梁格间空隙狭小且梁高较高，人工难以支模或浇筑后难以拆除的部位，该模板体系施工简单、拆模方便，能够有效解决狭长梁格内模板施工的难题，从而提高了整体施工效率。
