摘要
自平衡预应力中空管是一个新型预应力体系,施工方便、预应力值准确,即使锚筋长度很短也能准确实现,损失可控。介绍了预应力中空管的工作原理和施工工艺,同时通过产品性能试验,得出了部分预应力中空管设计参数,为今后产品的设计推广提供了有效依据。
The self-balancing pre-stressed hollow pipe is a new type of pre-stressed system. Its construction is convenient and the pre-stressing value is accurate. Even if the length of the anchor bar is very short, it can be realized accurately, and the loss can be controlled. This paper introduces the working principle and construction technology of the pre-stressed hollow pipe. Some design parameters of pre-stressed hollow pipe are all obtained through the product performance test, which can provide the effective basis for the design andpromotion of the products in the future.
