超大型高层建筑预应力无梁楼盖结构施工技术分析

Construction Technology Analysis of Prestressed Beamless Floor Structure of Super Large High-rise Building

超大型高层建筑工程中预应力无梁楼盖结构的应用,对施工技术、施工质量及施工安全要求非常严格。文中以某超大型高层建筑为例,对预应力无梁楼盖结构设计进行分析,同时对预应力无梁楼盖结构进行内力、抗弯承载力、裂缝和柱帽边缘冲切进行验算,探究预应力无梁楼盖结构的施工技术要点,为工程质量提供保障。

The application of prestressed beamless floor structure in super large high-rise building projects has very strict requirements on construction technology,construction quality and construction safety.This paper takes a super large high-rise building as an example,analyzes the design of prestressed non-beam floor structure,and verifies the internal force,flexural bearing capacity,cracks and edge punching of column cap of prestressed non-beam floor structure,explores the key points of construction technology of prestressed non-beam floor structure,and provides guarantee for project quality.
