The invention relates to the technical field of suspension bridge construction, in particular to a portal frame for hoisting a splay cable saddle, which comprises a vertical supporting unit, a horizontal supporting unit and a vertical supporting unit, the horizontal supporting unit is located above the vertical supporting unit, one end of the horizontal supporting unit is connected with the vertical supporting unit, the other end of the horizontal supporting unit is used for being anchored in the inclined anchor chamber side wall, and the position of the connecting point of the horizontal supporting unit and the inclined anchor chamber side wall is located above the position of the connecting point of the vertical supporting unit and the inclined anchor chamber side wall; and the hoisting mechanism is arranged on the horizontal supporting unit and used for hoisting the splay cable saddle. By directly anchoring the end part of the horizontal supporting unit in the side wall of the inclined anchor chamber, the use of a group of vertical supporting structures is reduced, the occupied space and the supporting height of the gantry are reduced, and the problems that the occupied space of the gantry is large, the supporting height is high and the hoisting cost is high when a floor type gantry is used for hoisting a splay cable saddle in the prior art are solved. The problems that a large amount of materials and time need to be consumed for construction, and construction efficiency is reduced exist.
本申请涉及一种用于散索鞍吊装的门架,涉及悬索桥施工技术领域,包括竖向支撑单元,其用于固定在倾斜锚室侧墙上;水平支撑单元,位于竖向支撑单元上方,水平支撑单元一端与竖向支撑单元连接,另一端用于锚固在倾斜锚室侧墙内,且水平支撑单元与倾斜锚室侧墙连接点位置位于竖向支撑单元与倾斜锚室侧墙连接点位置的上方;吊装机构,其设置在水平支撑单元上,用于吊装散索鞍。通过直接将水平支撑单元的端部锚固在倾斜锚室侧墙内,减少了一组竖向支撑结构的使用,减少了门架的占用空间和支承高度,解决了现有技术中采用落地式门架进行散索鞍吊装时,门架的占用空间大,支承高度高,存在需要消耗大量材料和时间建造,降低施工效率的问题。
