预应力混凝土后张T梁张拉体系质量控制

Quality control of the tension system of the prestressed concrete post-tensioned T-beam

通过对混凝土后张T梁的孔道成型,预应力锚固体系,预应力张拉及孔道压浆程序的控制,提出了一些张拉质量控制的措施,指出应通过不断摸索,不断改进施工过程中的薄弱环节,才能使预应力张拉施工质量得到有效控制。

Through the control of the hole forming of the concrete post-tensioned T-bcam, the prestressed anchor system, the prestress tension and the duct grouting process, the author puts forward the quality control measure of the tension, points out that the construction quality of the prestress tension can be controlled by continuously exploring and improving the weak link in the construction process.
