大柱距预应力无梁楼盖在多高层冷库中的应用

Big Pillars are Applied by Prestressless Beams

随着我国冷链物流快速发展,为满足提高冷库库容量及方便库体机械化操作等需求,大柱距预应力无梁楼盖相对传统梁板楼盖,因其综合技术指标优异,结构性能高等特点,在多高层冷库中得到广泛认可和运用。本文选取冷库项目实例,开展结构楼盖设计方案比选,分析比选方案的优缺点,并借助有限分析方法,阐述预应力无梁楼盖设计要点,旨在为冷库设计提供借鉴和参考。

With the rapid development of my country's cold chain logistics,in order to meet the needs of improving the capacity of the cold storage and the mechanization operation of the library body,the large pillar is a prestressed stressless beam building.Compared with the traditional beam and board cover.The characteristics are widely recognized and used in the high-rise cold storage.This article is selected from the cold storage project to carry out the selection of structural cover design schemes,analyzes the advantages and disadvantages of the selection scheme,and uses limited analysis methods to explain the main points of prestressed beamless floor cover design,which aims to provide reference and reference for the design of the cold storage.
