近年来随着我国高速公路建设的迅速发展,桥梁建设的施工技术也在不断提高。其中钢筋混凝土结构在桥梁建设中最为常见,特别是盖梁的施工,传统的施工工艺是搭设满堂架支撑体系,此种施工方法不仅浪费材料,而且耗工费时,采用悬空支撑法进行施工,就大大节省了周转材料,加快了施工进度。悬空支撑法通常分为钢棒支撑法和柱箍支撑法两种施工工艺,钢棒支撑法是在墩柱中预留孔,然后插入钢棒,作为盖梁的支撑点。这种施工工艺需事先
In recent years, with the rapid development of China’s expressway construction, the construction technology of bridge construction is also constantly improving. One of the most common in the construction of the bridge in the construction of reinforced concrete, in particular the construction of the cover beam, the traditional construction process is to set up a full frame support system, this method of construction not only waste materials, and time-consuming, the use of suspended support method for construction, Significant savings in working capital materials, speeding up the construction progress. Hanging support method is usually divided into two kinds of construction techniques: steel rod support method and column hoop support method. The steel rod support method is to reserve holes in the pier column, and then insert the steel rod as the support point of the cover beam. This construction process requires prior
