space frame Convenient and fast installation: 70% of the workload of bolted ball space frame structure is prefabricated in the factory, and only bolting is required at the site, which is relatively simple to operate, and only a spanner is needed to tighten the bolts, without large construction equipment and complex on-site welding operations, which can effectively shorten the construction cycle and improve the construction efficiency. In contrast, the welded ball grid structure has a large amount of on-site welding workload, is greatly affected by weather conditions, and the welding process is complicated and the construction speed is slow. High construction safety: when installing the bolted ball grid structure on site, the overhead welding operation is reduced, which reduces the fire risk and the safety hazard of the construction personnel due to welding sparks, high temperature and so on. At the same time, the operation of bolted connection is relatively simple and requires relative...

 There are a number of differences between bolted ball grids and welded ball grids in terms of fabrication, construction and design. The following are specific comparisons: 1. Manufacturing process: The manufacturing of bolted ball net frame is mainly carried out in the factory, using mechanical shot blasting to remove rust, and then spraying paint, plastic spraying or zinc spraying treatment to enhance corrosion resistance.  The steel pipe and welded seam of welded ball mesh frame can only be descaled manually on site, and then paint or fireproof coating is brushed. For the welded part, it needs to be descaled and brushed at a stage to maintain, which increases the cost of later use and affects the safety of the structure. 2. Construction process: 70% of the workload of bolted ball grid frame is prefabricated in the factory, 30% of the workload is installed at the site, only a wrench is needed to tighten the bolts at the site, which is easy and fast, and can be constructed ...

 INSTALLATION IN HIGH ALTITUDE The high-altitude installation method refers to the method of transporting the transport unit (plane truss or cone) or parts transported to the site, using a hoisting machine to lift it to a high altitude and assemble it into an overall structure. It is suitable for bolt balls or high-strength bolts. Grid structure. During the assembly process, a part of the space frame is always suspended. When the grid frame is suspended and spliced into a stable system, there is no need to set up any brackets to bear its own weight and construction load. Installation in high altitude When the span is large and spliced to a certain length of overhang, set up a single-leg column or bracket to support the overhanging part to reduce or avoid deflection due to self-weight and construction load

  The ground assembly method can be divided into several construction methods: a. On-site assembly and overall jacking The space frame  is assembled on the ground, and the fulcrum is set at the position of the column, so there is no need to stagger it, and then the space frame  is raised to the design level with a jack. b. On-site assembly and overall improvement The space frame  is fully assembled on the ground, and then the space frame  is raised to the design level by using the plate lifter or the sliding form lifting machine. c. On-site assembly, overall hoisting, and high-altitude displacement This method is to stagger the grid support from the position of the support column when assembling on the ground (when individual rods affect the lifting, they can not be assembled, but should be properly reinforced). Then use the hoist to lift the space frame , and then move the space frame  after it exceeds the top of the column, so that the support of the spac...

  The advantage of the space frame  structure is that all the components can be spliced and installed by the factory. It only takes 45 days to 2 months for the roof of a large-scale industrial plant, and 8 to 12 months if the reinforced concrete building is used. The short project cycle greatly reduces unnecessary costs.   Because the weight of the space frame  itself is light, under normal circumstances, it is not necessary to do pile foundations, which can save investment. According to the current domestic market price in China, the cost of light steel structure is already lower than that of reinforced concrete structure. When the span of the space frame  structure is larger, the use space can be greatly increased, and its advantages are more obvious, which is also one of the competitions it relies on. big advantage.   Generally, the truss can be designed with a span of about 20 meters, and the supporting columns should be placed. However, the span of the...

Common connection methods for steel structures : 1. A steel structure is made up of a number of elements combined. The role of the connection is to combine the plates or sections into members in a certain way, or to combine several members into a whole structure in order to ensure that it works together. Therefore, the connection method and its quality directly affect the working performance of the steel structure. 2. At present, the steel structure is commonly connected by welding, bolting or riveting. The earliest common bolt connection was used from about the middle of the 18th century, and the rivet connection was introduced in the 1920s, while the weld connection appeared in the second half of the 19th century. Since the middle of the century, high-strength bolted connections have been developed.
