Construction mould and construction method for outer floating roof of large storage tank

LIN XINTAO

The invention discloses a construction mould and construction method for an outer floating roof of a large storage tank. The construction mould comprises a stand column, an adjusting rod, an adjusting piece system and a connecting beam, and is characterized in that the adjusting rod is coaxially arranged in the stand column, a plurality of pairs of oppositely-opened adjusting holes are formed in the adjusting rod in the vertical direction, positioning holes are formed in the upper end of the stand column, connecting pieces penetrate through the positioning holes and the adjusting holes to fix the stand column and the adjusting rod, the top of the adjusting rod is connected with the adjusting piece system, the adjusting piece system can finely adjust the distance between the top end of the adjusting piece system and the top end of the adjusting rod, and the end of the connecting beam is fixed to the top end of the adjusting piece system. The construction mould has the advantages that the requirements of safety, mounting quality and complete overall functions of the floating roof can be met, and meanwhile the requirements of quick mounting, quick dismounting, high standardization degree, high repeated utilization rate and cost saving in engineering can be met.

本发明公开了一种大型储罐外浮顶施工胎具及施工方法，施工胎具包括立柱、调整杆、调节件系统和连接梁，特点是：调整杆同轴设置在立柱内，调整杆上沿竖直方向设置有多对对开的调节孔，立柱的上端部设置有定位孔，通过连接件穿过定位孔和调节孔将立柱与调整杆固定，调整杆的顶部与调节件系统连接，调节件系统能够微调其顶端与调整杆顶端的间距，连接梁的端部与调节件系统的顶端固定，优点是：既能保证浮顶安全性、安装质量以及整体功能完备的要求，同时也能够满足工程上实现快装、快拆、标准化程度高、重复利用率高、成本节约的需求。
