双向预应力楼板是北京市建筑设计院为北京十六层外交公寓设计的。生产双向预应方楼板对我厂来说是一个新课题。在市设计院和有关单位密切配合,大力支持下,经过反复试验,已于72年冬试制成功,并已在三层试验楼和十六层公寓中使用。通过试验楼进行的一系列结构试验,证明这种楼板在强度、刚度和保证建筑物结构的整体性等方面基本上满足了设计要求。
The two-way prestressed floor slab was designed by the Beijing Architectural Design Institute for the 16-floor diplomatic apartment in Beijing. The production of two-way precast floor slabs is a new topic for our plant. In close cooperation with the relevant units in the City Design Institute, with strong support, after repeated trials, has been successful in the winter of 72 trials, and has been used in the three-story test building and 16-storey apartment. Through a series of structural tests conducted by the test building, it is proved that such a floor basically satisfies the design requirements in terms of strength, stiffness, and the integrity of the building structure.
