Comparison Of Welded And Bolted Ball Netting Structures

 Comparison of welded and bolted ball netting structures

space frame


Analysis in terms of quality assurance.

1, welded ball structure using hollow ball (material Q235 ordinary steel) and welded pipe on the site of the welding, by the temperature and wind speed, under the influence of the welding machine equipment and basic artificial manual, resulting in the material, positioning, welding process, error, low precision. The steel has stress deformation before and after welding, which is a safety hazard. The angle control between the various bars is not accurate after use, which can easily distort the bars and destroy the balance of force transmission. It is not possible to adapt to the requirements of shaped curves and oversized spans, and the quality is difficult to guarantee, so there are great limitations.

2、Bolt ball structure is made of solid ball (material 45# high strength steel) and high strength bolt (material 40Cr), which are closely jointed. The angle between the screw holes on the bolt ball is precise, and the bar has built-in 10.9S high-strength bolts, which are tensile and compressive, and the force transmission is stable and balanced.

The development status of the space frame structure

The development status of the space frame structure space frame   structure has been developed greatly in the last 30 years, and has been widely used inside and outside. space frame   structure plan arrangement is flexible, space shape is beautiful, convenient for building shape processing and decoration, decoration, can adapt to different span, different plane shape, different support conditions, different functional needs of the building.   Especially in the roof structure of large and medium span, the space frame   structure shows its superiority and is used in large number of large sports buildings, public buildings, industrial buildings, and also widely used in the roof of some small buildings, such as gas stations, toll stations, large canopies. In recent years, with the wide application of electronic computers and the development of computing technology, the design efficiency of the space   frame structure has been greatly improved. The construction and installation of the space

Cooling method of steel building structure

 Steel structure plant mainly refers to the main load-bearing components are composed of steel. Including steel columns, steel beams, steel structure foundation, steel roof truss (of course, the span of the factory is relatively large, basically now are steel structure roof truss), steel roof, pay attention to the wall of steel structure can also be maintained by brick wall. Due to the increase of China's steel production, many have begun to use steel structure plants, which can also be divided into light and heavy steel structure plants. Industrial and civil construction facilities made of steel are called steel structures. 1. Heat preservation and cooling: Steel structure plant insulation film can isolate most of the solar radiation and conduction heat, reduce the indoor greenhouse effect. Then the temperature of the plant is greatly reduced to improve the environment of the steel structure plant. The commonly used methods now have the following two choices: the steel structure

What is the truss welding method?

图片
  truss roof Most of the rods in joist structures are welded at the nodes. Before welding, the webs and chords need to be cut in advance according to the shape of the weld seam of each member to be welded, which requires cutting of the web ends and slotting of the chords. Since the joist structure is intersected by coherent line between the rods and rods, the shape of rod end section is complicated, so in the actual cutting process, two methods of mechanical automatic cutting process and manual cutting process are generally used.
