摘要
确定合理的张拉施工工艺是确保有效预应力的建立、方便施工、保证屋架施工质量的重要前提。本文从多个角度分析了折线型屋架预应力单端张拉工艺的合理性、可行性,同时探讨了叠层生产的屋架的张拉问题。可供类似工程施工借鉴。
A reasonable tension process is an important prerequisite to ensure the effective establishment of pre-stress and to ensure construction quality expediently of roof trusses. This article analyzes the rationality and the feasibility of single-ended prestressed tension process in the polygonal line-type roof truss from various angle,st and the tension problem of laminated production roof truss is analyzed, h can provide construction reference for similar projects.
