關于市中鋼結構工程的螺栓連接施工怎樣質量控制？

?關于鋼結構工程的螺栓連接施工怎樣質量控制？高強度螺栓連接工程也是鋼結構工程最重要的分項之一，也是目前施工質量的薄弱環(huán)節(jié)之一，主要表現(xiàn)在：

（l）高強度螺栓有以次充好現(xiàn)象，（用普通精制螺栓代替高強度螺栓）；

（2）高強度螺栓連接面處理達不到規(guī)范規(guī)定要求，包括表面處理情況，平整密貼情況，螺栓孔質量情況等；

（3）高強度螺栓施擰不按規(guī)范規(guī)定進行，如不分初擰、終擰而一次完成，不用扭矩扳手、全憑主觀估計等。

為保證高強度螺栓連接工程的施工質量，監(jiān)理工程師必須以高度的責任心，在督促承包單位提高質量意識、加強質量管理、落實質量保證措施的同時，積極采用旁站監(jiān)督、平行檢驗等工作方法，只有這樣才能使高強度螺栓連接工程的施工質量處于嚴格的控制之下。
