Prefabricated inverted arch bridge girder erection machine and using method thereof
A prefabricated inverted arch bridge erecting machine comprises a first supporting mechanism, a prefabricated inverted arch hoisting trolley, a hoisting support and a bridge body arranged in the longitudinal direction, the bridge body is arranged on the first supporting mechanism in a liftable mode, longitudinal guide rails are arranged on the portions, on the two longitudinal sides of the first supporting mechanism, of the hoisting support, and the longitudinal guide rail on at least one side can move in a reciprocating mode. And the prefabricated inverted arch hoisting trolley is arranged on the longitudinal guide rail. The using method comprises the steps that S1, before the prefabricated inverted arch constructed in the previous working procedure does not bear load, the bridge body serves as a vehicle passing channel; s2, the bridge body ascends along the first supporting mechanism, passes through a gap between the longitudinal guide rails on the two sides and then reaches the position above the hoisting support, and the longitudinal guide rails on the two sides are in butt joint; s3, the prefabricated inverted arches to be hoisted are hoisted to the corresponding installation positions through the prefabricated inverted arch hoisting trolley; s4, the longitudinal guide rails on the two sides are separated, and the bridge body descends to serve as a vehicle passing channel. The prefabricated inverted arch is simple in structure, multiple prefabricated inverted arches can be installed at a time, vehicles can pass in time, and the construction efficiency can be improved.
一种预制仰拱架桥机，包括第一支撑机构、预制仰拱吊装小车、吊装支架及沿纵向布置的桥体，桥体可升降的设于第一支撑机构上，吊装支架于第一支撑机构纵向两侧设有纵向导轨且至少一侧的纵向导轨可往复运动，预制仰拱吊装小车设于纵向导轨上。其使用方法：S1、上一工序施工的预制仰拱未能承重之前，桥体作为过车通道使用；S2、桥体沿第一支撑机构上升通过两侧纵向导轨之间的间隙后到达吊装支架上方，两侧的纵向导轨对接；S3、预制仰拱吊装小车将各待吊装的预制仰拱吊装至对应的安装位置；S4、两侧的纵向导轨分离，桥体下降作为过车通道使用。本发明结构简单，可以一次性安装多块预制仰拱，车辆可以及时通行，有利于提高施工效率。
