Transverse multi-box-chamber steel beam construction method
The invention provides a transverse multi-box-chamber steel beam construction method, which belongs to the technical field of steel beam installation, and comprises the following steps: splicing a plurality of steel beam sections into a pre-assembled steel beam; the multiple steel beam sections are labeled, and target paper is pasted; establishing a reference point A outside the pre-assembled steel beam, erecting a plurality of three-dimensional laser scanners, determining initial coordinate data of each piece of target paper by taking the reference point A as a reference, and establishing a pre-assembled steel beam attitude model; comparing the pre-assembled steel beam posture model with a preset steel beam posture model to obtain a target posture model, and determining target coordinate data; and a plurality of three-dimensional laser scanners are erected on the periphery of the bridge support, a site reference point A1 is determined, site coordinate data are compared with target coordinate data, and the position of the first steel beam section is adjusted until the site coordinate data are matched with the target coordinate data. The construction method of the transverse multi-box-chamber steel beam is easy to operate, and the positioning accuracy of the steel connecting section can be effectively improved.
本发明提供了一种横向多箱室钢梁施工方法，属于钢梁安装技术领域，包括以下步骤：将多个钢梁节段拼成呈预拼装钢梁；对多个钢梁节段进行标号，并张贴标靶纸；在预拼装钢梁外建立基准点A，架设多台三维激光扫描仪，以基准点A为基准确定各个标靶纸的初始坐标数据，建立预拼装钢梁姿态模型；将预拼装钢梁姿态模型与预设钢梁姿态模型进行对比，获取目标姿态模型，确定目标坐标数据；在桥梁支架的外围架设多台三维激光扫描仪，确定现场的基准点A1，将现场坐标数据与目标坐标数据进行对比，并调整1号钢梁节段的位置，直至现场坐标数据与目标坐标数据相吻合。本发明提供的横向多箱室钢梁施工方法操作简单，且可有效提高钢连节段的定位准确性。
