Formwork erecting device for bridge construction
The invention discloses a formwork erecting device for bridge construction, which comprises a main support hanging cable which is arranged on a crane cantilever and can be freely rolled, and a hanging plate which is used for hanging a bridge pier steel formwork arranged on the outer ring of a bridge pier reinforcement cage in a sleeving manner, and the top of the bridge pier reinforcement cage comprises a top reinforcement joint area without stirrups; the hoisting plate is provided with a closing-in structure for preventing the longitudinal stress main reinforcement at the top reinforcement joint area from hindering lowering of the bridge pier steel formwork, and the crane cantilever is provided with a circuit control assembly for adjusting the power-on state of the electromagnet according to the hanging length of the main supporting hanging cable. The diameter of the steel bar is adjusted to meet the requirement of the formwork, so that the formwork can be smoothly and accurately placed at a designated position, the construction risk caused by unmatched steel bars is reduced, the formwork erecting speed can be remarkably increased by automatically adjusting the closing-up process of the top steel bars, and then the construction efficiency is improved.
本发明公开了一种桥梁施工用模板架设装置，包括设置在起重机悬臂上可自由收卷的主支吊缆，以及用于悬挂套设在桥墩钢筋笼外圈的桥墩钢模板的吊装板，桥墩钢筋笼顶部包括未设置箍筋的顶部钢筋接头区域，吊装板上设有防止顶部钢筋接头区域处纵向受力主筋阻碍桥墩钢模板下放的收口结构，起重机悬臂上设有根据主支吊缆吊挂长度调节电磁铁通电状态的电路控制组件，本发明通过收口结构，能够自动调整桥墩钢筋笼顶部的敞口，使其直径符合模板的要求，从而确保模板能够顺利、精确地下放到指定位置，减少因钢筋不配合而造成的施工风险，并能够通过自动调节顶部钢筋的收口过程，显著提高了模板架设速度，进而提高施工效率。
