波形钢腹板PC箱梁部分承重式挂篮
摘要：
本发明公开了一种波形钢腹板PC箱梁部分承重式挂篮。其包括：挂篮桁架；挂篮固定装置，其固定在前一节段的混凝土上，该挂篮固定装置的一端具有挂篮后支点基础；挂篮后支点，其布设在所述挂篮桁架的后端，并与所述挂篮后支点基础连接；挂篮前支点，其布设在所述挂篮桁架的中部，并通过挂篮前支点基础与本节段的波形钢腹板连接；吊装设备，其布设在所述挂篮桁架的前端，用于吊装后一节段的波形钢腹板；以及工作平台，其布设在所述挂篮桁架的下方。该波形钢腹板PC箱梁部分承重式挂篮减少了挂篮荷载对于浇筑初期的预应力混凝土箱梁产生的拉力。
摘要（英）：

The invention discloses a corrugated steel web PC box girder partly bearing type hanging basket. The hanging basket comprises a hanging basket truss, a hanging basket fixing device, a hanging basket rear fulcrum, a hanging basket front fulcrum, hoisting equipment and a working platform, wherein the hanging basket fixing device is fixed on the concrete of the previous section, one end of the hanging basket fixing device is provided with a hanging basket rear fulcrum foundation, the hanging basket rear fulcrum is arranged at the rear end of the hanging basket truss and is connected with the hanging basket rear fulcrum foundation, the hanging basket front fulcrum is arranged in the middle of the hanging basket truss and is connected with a corrugated steel web plate of the section through a hanging basket front fulcrum foundation, the hoisting equipment is arranged at the front end of the hanging basket truss and is used for hoisting the corrugated steel web of the latter section, and theworking platform is arranged below the hanging basket truss. According to the corrugated steel web PC box girder partly bearing type hanging basket, the pulling force generated by the hanging basketload on a prestressed concrete box girder at the initial stage of pouring is reduced.
