Large-span pipe truss construction technology

The basis of the tube truss structure of large-span buildings is the grid structure, and the tube truss structure is the technical extension and development of the grid structure. Compared with the traditional mesh structure, the tube truss structure reduces the amount of steel. As a typical representative of the space system, the mesh structure must be considered in terms of stress area, stress points, stress limits and the overall structure. Compared with the grid structure, the long-span tube truss structure saves economic costs.
Before the pipe truss is hoisted, the pipe truss hoisting plan must be optimized and designed in order to master the hoisting construction technology. Various methods such as segmented rotation, overall hoisting, and high-altitude scattered assembly are mainly used.

Assembled tube truss technology: Use level detectors during assembly to ensure that the entire tube truss is assembled with good levelness and precision;

Welded pipe truss technology: During the welding process, ensure that the welding balls are of high quality. After the welding is completed, the assembly port should be polished to reduce the wear rate of the pipe truss.
Re-inspection of embedded parts technology: Re-inspection of embedded parts mainly refers to re-inspection and recording of the details of assembled and welded pipe trusses.
Before the construction of the pipe truss, it is necessary to have good communication with the crane driver to clarify the lifting route and ensure the lifting stability. Before the pipe truss is officially lifted, the relevant lifting tools need to be comprehensively and systematically inspected to eliminate all unstable factors. Avoid adverse effects on the tube truss structure. Pipe truss cranes need to strictly control the lifting route and speed, and strictly follow the markings from the starting point to the end point.
In order to effectively prevent the influence of external environmental factors on the quality of the pipe truss structure, certain welding, painting, etc. are required after assembly. In order to effectively stabilize the pipe truss structure, a large number of auxiliary components are required for optimization. In order to ensure the overall construction quality, all Accessory components need to be assembled on the ground.

As modern construction becomes increasingly concerned with aesthetics and economic safety, tube truss design and construction techniques continue to evolve. Due to the characteristics of efficient, fast, high-span and light weight construction of pipe trusses, it can be applied to the construction of industrial plants in different types and environments. In the context of the rapid development of social economy and social science and technology, the development of various industry fields continues to improve the quality of their products and the safety of their factories.
