Description

A tube truss is a lattice structure composed of round rod members connected at the ends. The truss makes the truss structure economical in material, light in dead weight, and easy to form various shapes to adapt to different uses, such as simply supported trusses, arches, frames and pylons. The truss refers to the lattice structure composed of the rods connected at the end, and the pipe truss refers to the round pipe rods in the structure. In most cases, the rod members in the truss are only subjected to axial tension or pressure, and the stress is evenly distributed on the cross section, so it is easy to play the role of materials. These characteristics make the truss structure economical with materials and the structure weight is small. It is easy to form a variety of shapes to adapt to different uses, such as simply supported trusses, arches, frames and pylons, etc., so the truss structure has been widely used in many large-span stadium buildings today, such as exhibition centers, sports venues or some other large public buildings.

The rods in some truss structures are connected by welding at the nodes. Before welding, it is necessary to pre-cut the web and chord according to the shape of the welding seam of each rod to be welded, which requires the end of the web. The head performs intersecting line cutting and chord slotting cutting. Since the rods in the truss structure intersect with each other in the form of intersecting lines, the cross-sectional shape of the rod ends is relatively complex, so in the actual cutting process, two methods of mechanical automatic cutting processing and manual manual cutting processing are generally used. processing.

Compared with the grid structure, the pipe truss structure omits the bottom chord longitudinal members and the ball joints of the grid, which can meet the requirements of various architectural forms, especially the construction of circular arches and arbitrary curved shapes is more advantageous than the grid structure. It has the same stability in all directions, saving material consumption. The steel pipe truss structure is developed on the basis of the grid structure. Compared with the grid structure, it has its advantages and practicability, and the amount of steel used for the structure is more economical.

Compared with the traditional open-section (H-beam and I-beam) steel trusses, the section material of the pipe truss structure is more evenly distributed around the neutral axis, so that the section has good compressive and bending torsional bearing capacity and greater rigidity at the same time. No gusset plate, simple construction. The important thing is that the pipe truss structure has a beautiful appearance, which is convenient for modeling and has a decorative effect.
