碗扣满堂支架法在盖梁施工中的应用

The Application of Full Space Support with Bowl Buckle Scaffold in Coping Construction

跨铁路公路立交桥高墩盖梁模板支撑体系的稳固与否直接关系到铁路运营安全,碗扣式脚手架作为高墩盖梁模板支撑体系以其拆卸迅速简便、承载能力大、安全可靠等特点得到了广泛的认可,而脚手架立杆的稳定性是脚手架支撑体系稳定的关键。以某跨铁路的公路桥高墩盖梁模板支撑体系为例,对碗扣式支撑体系的稳定性进行了分析验算,确定了盖梁模板支护方案并应用于漾泉大道跨白荫支线改线立交桥工程,应用效果良好。

The stability of high pillar coping template support system for road overpass over railway is crucial for the operation safety of the railway. The bowl buckle scaffold as the support system for the high pillar coping is widely accepted for its simple installation,great carrying capacity,and reliability. The stability of the upright stanchion is the key for the stability of the scaffold support system. Taking the high pillar mode support system of road bridge over railway as an example,the paper analyzes the stability of bowl buckle support system and determines the support scheme. The scheme was applied in the overpass bridge on relocation project of Yangquan Road over Baiyin branch,which achieved good effect.
