Abstract
The utility model belongs to the technical field of the steel construction, especially, relate to a prestressing force pipe truss structure of more effectual transmission gable horizontal force. The multi-truss structure comprises five parts, namely a multi-truss chord pipe truss main structure, a connection truss, a side truss connection truss, a gable pipe truss main structure and a horizontal supporting structure. The multi-beam chord pipe truss main structure connects the main structures together through the connection truss, and then the side beam connection truss connects the gable main structure and the multi-beam chord pipe truss main structure together for ensuring the stability outside the structural plane. The horizontal force born by the prestressed pipe truss structure is directly transmitted to the side truss connection truss through the gable truss and then transmitted to the inner side connection truss gradually through the side truss connection truss. The improved side truss connection truss is only rigidly connected with the gable truss through the upper chord, so that the optimized connection truss can more effectively transfer horizontal force, the welding difficulty of the rod piece is reduced, and the material cost is reduced.
