钢筋墩粗套筒连接技术应用

Application of Connection Technology of Thick Sleeve Reinforcement

钢筋接头一直是受力薄弱处,其质量好坏对非预应力工程实体抵抗拉应力影响较大。自机械连接在我国发展以来,经过多年探索发展,钢筋墩粗套筒连接技术逐步成熟,近几年逐步引入高速公路建设。渭武高速公路项目施工标准化管理要求为契机,在本项目部推行直径不小于25 mm钢筋采用墩粗套筒连接。

The steel joint has always been weak,and its quality is very good for the non-prestressed engineering entity to resist the tensile stress.Since the mechanical connection in China since the development,after years of exploration and development,reinforced pier thick sleeve connection technology gradually mature,in recent years the gradual introduction of highway construction.Weiwu expressway project construction standardization management requirements as an opportunity,in the project department to implement the diameter ≥ 25 mm reinforced with a thick sleeve connection.
