Grid structure sleeve bolts - Processing, design and installation methods for bolted spherical grid structures

Product quality problems that occur during the production, processing and installation of bolted spherical node grid structures, such as incomplete welding, weld beads, inclined cone heads, non-falling fillets at the junction of cone clamps, cone walls and base plates, wedge-shaped horseshoe-shaped joints, and component collisions at nodes, etc. Based on the design plan, fabrication and installation of grid structures, some viewpoints are put forward on issues such as the slenderness ratio of components, the selection of adjustment part components and rubber bearing methods in the design plan of bolted spherical node grid structures, the selection and installation of parts and components, and the estimation of steel content used by enterprises. And in light of actual engineering projects, clearly put forward solutions to some practical problems in the production and installation. Grid structure sleeve bolts.

Due to its numerous advantages, grid structure engineering has become one of the structural forms that have developed more rapidly and are widely used in China's spatial layout in recent years. In today's society, the construction industry is developing rapidly. People will see all kinds of different steel structure projects. Among them, many large and medium-sized sports venues and gas stations are all made of steel frame grid structures. When installing the grid structure in the design plan of a gas filling station, there are many points to pay attention to. So, do you know what the installation methods of the grid structure design plan of a gas filling station are? What should be noted when installing the production and processing design plan of bolted spherical grid structures?

When we are installing the grid structure of the dry coal shed, we must strictly follow the manufacturing standards to prevent any violations. For instance, the installation of simple steel beam components often leads to an unstable structural management system, resulting in collapse. In the case of grid structure application, if the design elevation of the anchor bolts is inconsistent and there are errors in the specifications, it is very likely to cause the entire project to tilt. In addition, when we are carrying out the design plan for the grid structure project, the structure and quality of the grid structure, as well as the quality of the screw parts, must all undergo detailed inspections. Once the quality of the anchor bolts is found to be substandard, they need to be replaced immediately. In that case, it is very likely that a solid structural management system cannot be ensured throughout the entire construction process. Therefore, the tightening torque should be strictly calculated to reduce errors and avoid affecting the operation of the entire grid structure. Grid structure sleeve bolts.

For the installation methods of the production and processing design plan of bolted spherical grid structures, the common key methods include the high-altitude loose weighing method, the slitting or layer-based installation method, as well as the overall lifting method and the overall lifting method, etc. The types of grid structures available for different installation methods are all different. In addition, when carrying out the electric welding of the grid structure, it is necessary to ensure that the electric welding is carried out in a timely manner, complete the regulations for electric welding in the grid structure project, and prevent a large number of air holes.

The high-altitude scattered weighing method is mainly applicable to various types of grid structure manufacturers with screw connection nodes. In many cases of smaller grid structure design and installation, you can choose the cutting or layer-based installation method, depending on the load-bearing capacity of the grid structure.
