近年来,有粘结预应力混凝土梁以其抗裂强度高,能充分利用高强度钢材的潜能,节约钢材并减少梁截面尺寸和混凝土用量,具有显著的经济效益的优势,从而被推广应用于民用房屋建筑工程中。但在施工方面,有粘结预应力梁增加了埋设波纹管、孔道灌浆等工序,在张拉端的处理也较为复杂。本文作者根据工程的监理经验,对后张有粘结预应力混凝土梁的施工工艺要点和质量控制措施做了浅析。
In recent years, bonded prestressed concrete beams with its high rupture strength, can take full advantage of the potential of high-strength steel, saving steel and reduce the beam section size and the amount of concrete, with significant economic benefits, which has been widely applied Civil housing construction. However, in the construction, there are bonded prestressed beams to increase the laying of corrugated pipe, hole grouting and other processes, the processing is also more complicated at the end of the tension. According to the engineering supervision experience, the author analyzes the construction process and quality control measures of the post-tensioned bonded prestressed concrete beams.
