Method for installing steel-structure roof string beam segment by segment

Abstract

The invention provides a method for installing a steel-structure roof string beam segment by segment. A whole roof string beam structure is divided into segments through a computer simulation technology, and after installing segment by segment is conducted, the segments are assembled into a whole. According to the method for installing the steel-structure roof string beam segment by segment, a temporary support structure is adopted, a movable horizontal tie bar is installed on the temporary support structure, installing segment by segment and cable installing of the string beam are simultaneously met through the support structure, and the problem that after the roof string beam is installed segment by segment, cable installing is difficult is solved. The method for installing the steel-structure roof string beam segment by segment is high in operability and high-altitude installing efficiency, improves the positioning accuracy of roof string beam installing segment by segment simultaneously, reduces the error rate, improves the quality of steel structure construction, and reduces the installing risk of a steel structure.

Description

technical field [0001] The invention relates to a construction method of a steel component, in particular to a construction method for installing roof string beams in sections. Background technique [0002] At present, steel structures are more and more widely used in the field of civil engineering construction technology. However, as long-span roof structures are being used more and more, due to the sharp increase in their own weight, the overall structure is facing contradictions between the use function, design rationality and economic indicators. In order to meet the use function of the structure, reduce the The self-weight of the structure, improving the structural rigidity, and the prestressed string beam structure with cables are more and more used in large steel structure buildings. Through the arrangement of prestressed cables and struts, the bearing capacity and stiffness of the large-span space steel structure have been greatly improved. The string string struct...
