 The primary goal of a toll station canopy is to provide shelter and clear passage. However, outdated designs with numerous supporting columns can impede traffic flow, reduce visibility, and even pose safety risks for drivers. Modern toll station design demands: Unobstructed Traffic Flow:  Maximizing throughput is key. Canopies that eliminate central columns allow for wider, clearer lanes. Enhanced Driver Visibility:  A clear view of the road ahead and signage improves safety and reduces driver confusion. Architectural Integration:  The canopy often serves as a prominent visual element, contributing to the overall aesthetic of the infrastructure. The Power of Large-Span Steel Canopies At SAFS Steel Structure, we specialize in engineering and fabricating large-span steel canopy solutions that address these critical needs. Our expertise in structures like steel trusses and space frames allows us to create canopies that: Maximize Clear Span:  Steel's exceptional st...

 The bolt ball node is mainly composed of the following parts: Steel ball: Material: forged or cast solid steel ball, but the inner part is actually hollow to reduce weight. Role: As the core component of the connection, the steel ball is drilled and turned out according to the angle of convergence of the net frame rods, and is used to connect with the bolts. Bolt: Material: high strength bolt to ensure the reliability and durability of the connection. Role: Connect the steel pipe members and steel balls together by bolts to form a whole structure. The diameter and length of the bolts are selected according to the force demand. Sleeve: Shape: usually a hexagonal sleeve for easy screwing. Role: Sleeve on the screw of the bolt, by unscrewing the sleeve can drive the bolt to rotate, so as to realise the connection between the bolt and the steel ball. Pins or screws: Function: used to fix the bolt and sleeve together, preventing the sleeve from falling off in the process of unscrew...

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...

  Concrete Steel Structure 1. The process is more complex, high quality requirements, thus requiring a more skilled professional team, and there are problems of interspersed types of work. 2. Sub-stress. Secondary stresses due to prestressing, creep and shrinkage effects, temperature variations, and bearing subsidence can be severe in continuous structures unless these are controlled or accounted for in the design. In prestressed continuous structures, it is interesting to note that these secondary stresses can often be exploited advantageously, and thus the secondary stresses will increase the economy of the structure. 3. Friction losses in continuous force bars. Friction losses can be significant if there are many reverse curves, if the curves have large deflection angles, or if the force bars are too long. In beams with corrugations or added axils, friction losses can be minimised by using straighter cables. The usual methods of over-tensioning and tensioning from both ends can ...

  Despite the many advantages of steel structure design in modern buildings, there are some design difficulties. The following are the main difficulties in steel structure design: steel structure 1. Complex mechanical analysis · Multi-directional force: Steel structures are usually subject to multiple loads, including vertical loads, wind loads, seismic loads and so on. The combination and transfer path of these loads are complex and require accurate mechanical analysis. · Large-span structures: Large-span steel structures such as stadiums and exhibition centers require precise force analysis to ensure the stability and safety of the structure. 2. Node design · Node Complexity: The design of nodes (connection points) in steel structures is very complex, especially for space frames and shaped structures. Nodes need to transmit and distribute multidirectional loads, and have high design and construction requirements. · Welded and bolted connections: nodes are connected in various wa...

  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...
