Continuous beam cantilever hanging basket construction method
The invention relates to a construction method of a continuous beam cantilever hanging basket. The construction method comprises the following steps that a rear upper cross beam is installed at the top of an erected bridge section; hoisting the bottom die truss on the ground by utilizing hoisting equipment, so that the rear end of the bottom die truss is fixed with the erected bridge section through a rear hoisting rod I and is fixed with the rear upper cross beam through a rear hoisting rod II; in the longitudinal bridge direction, the hoisting points of the first rear hoisting rod, the second rear hoisting rod and the bottom die truss are located behind the gravity center of the bottom die truss, and the rear end of the bottom die truss abuts against the bottom face of the erected bridge section. The hanging point of the bottom formwork truss is located behind the gravity center of the bottom formwork truss and is fixed to the rear upper cross beam and the erected bridge section in a hanging mode, the hanging point at the front end of a traditional bottom formwork truss is omitted, only the hanging point of the rear upper cross beam is reserved, the rear end of the bottom formwork truss abuts against the bottom of the erected bridge section, and therefore the bottom formwork truss keeps balanced and stable, and the construction efficiency is improved. Therefore, the construction space of the to-be-erected bridge section is released, the subsequent hoisting construction of the to-be-erected bridge section is facilitated, and the construction procedure is simplified.
本发明涉及一种连续梁悬臂挂篮施工方法，包括以下步骤：在已架桥梁段的顶部安装后上横梁；在地面利用吊装设备吊装底模桁架，使底模桁架的后端通过后吊杆一与已架桥梁段固定，并通过后吊杆二与后上横梁固定；其中，沿纵桥向，后吊杆一和后吊杆二与底模桁架的吊装点位于底模桁架重心的后方，且底模桁架的后端与已架桥梁段的底面相抵。本发明的底模桁架的吊挂点位于自身重心的后方，与后上横梁和已架桥梁段悬挂固定，取消了传统底模桁架前端的吊挂点，只保留了后上横梁的吊挂点，而底模桁架的后端会与已架桥梁段的底部相抵，使底模桁架保持平衡稳定，从而释放了待架设的桥梁段施工空间，便于后续待架桥梁段的吊装施工，简化了施工工序。
