Steel truss girder assembly linear control method
The invention relates to the technical field of engineering construction auxiliary equipment, in particular to a steel truss girder assembly linear control method which comprises the following steps: setting a starting point and an ending point of an initial longitudinal axis of a steel truss girder to be assembled, and setting four intervisible control points around a position to be assembled of the steel truss girder by taking the initial longitudinal axis as a reference; arranging an observation platform on the extension line of the initial longitudinal axis at a first set distance from the starting point, erecting a total station, observing the four control points in sequence, obtaining plane coordinates of the four control points, and establishing a steel truss girder assembly control network; and assembling the steel truss girder, and when each steel truss girder section is assembled, determining the coordinate of the observation platform based on the steel truss girder assembling control net, and then carrying out steel truss girder assembling jig frame linear measurement and lower chord linear measurement. The problems that geological sedimentation or foundation extrusion causes displacement of the observation platform, and assembly linear control is affected can be effectively solved.
本发明涉及工程施工辅助装备技术领域，具体涉及一种钢桁梁拼装线形控制方法，该方法包括以下步骤：设定拟拼装钢桁梁初始纵向轴线的起点和终点，以初始纵向轴线为基准，在钢桁梁的拟拼装位置周围设置四个可通视的控制点；在初始纵向轴线的延长线上距离起点第一设定距离设置观测平台，并架设全站仪，依次观测四个控制点，获得四个控制点的平面坐标，建立钢桁梁拼装控制网；拼装钢桁梁，并在每一钢桁梁节段拼装时，基于钢桁梁拼装控制网确定观测平台的坐标后，进行钢桁梁拼装胎架线形测量、下弦线形测量。能够有效解决地质沉降或者地基受到挤压，从而引起观测平台发生位移，导致影响拼装线形控制的问题。
