跨度为40m的预弯预应力组合梁采用双榀预压施工技术,对浇筑一期混凝土后的反向梁进行翻转操作,使同时预压的两榀梁均为正向。本文通过工程实例,介绍了预弯梁翻转的思路及主要控制技术。
Pre-bent prestressed composite beam with a span of 40m adopts the double-bow pre-compression construction technology to invert the inverted beam after pouring the first-stage concrete so that the two precast beams with the same pre-compression are both positive. This article through the example of engineering, introduces the pre-bending beam overturning ideas and the main control technology.
