Horizontal warehouse prestress arch plate installing construction method
A horizontal warehouse prestress arch plate installing construction method is characterized by comprising the following steps that a, a plurality of flying rings, a steel beam and a steel support areprefabricated; b, a horizontal warehouse arch plate is prefabricated in the air; c, a jacking device is arranged; and d, a sliding device is arranged, two hydraulic jacks slowly jack the lower portions of the two ends of the steel beam at the same time, after the steel beam makes tight contact with the flying rings and qualification is confirmed, synchronous jacking continues, the jacking processof the two jacks needs to be slow and synchronous, simultaneous two-end jacking is not allowed, after the arch plate is jacked by the height of 150 mm, the arch plate disengages from the ring beam face, a sliding trolley is arranged at the disengaging position, the jacks synchronously descend, the arch plate is located on the trolley, and the steel beam, the jacks and a base are dismounted. The horizontal warehouse prestress arch plate installing construction method has the advantages that the device structure is simple, manufacturing is convenient, the engineering quality is safe and reliable, the original section size design of a ring beam is kept, the aerial sliding technology is improved, the construction period is shortened, and the engineering cost is reduced.
一种平房仓预应力拱板安装施工方法，其特征在于包括以下步骤：a、预制若干吊环、钢梁、钢支座，b、在高空预制平房仓拱板，c、设置顶升装置，d、设置滑移装置，其中：两台液压千斤顶同时缓慢顶升钢梁两端下部，钢梁及吊环接触紧密后，确认合格后再继续同步顶升；两台千斤顶顶升过程应缓慢同步，不得两端同时进行顶升；拱板被顶升150mm高度后，与圈梁面脱离，在脱空位置安放滑移小车，千斤顶同步下降，使拱板坐落在小车上，拆除钢梁及千斤顶、底座。本发明的平房仓预应力拱板安装施工方法具有装置结构简单、制作方便，工程质量安全可靠、保持圈梁原有截面尺寸设计，完善高空滑移工艺，缩短工期和降低工程成本的优点。
