Grid Accessory Rod Manufacturing Process

The raw materials of the steel pipes should be reviewed before cutting, and they can only be delivered after they are qualified. The HID-900MTS CNC lathe water pipe intersecting line cutting machine is used for cutting, and the fiber laser cutting quality of grid parts meets the technical standards. The cone head of the grid parts is cut from round steel. The cone head blank cannot experience defects such as burning and cracks before forging. After forging, quenching process is required to remove the oxide scale. After the cone head is forged and shaped, the milling machine is used to process the indoor stairs that complement the cone head and the inner wall of the rod tube, the plane design of the small end of the cone head, and the electric welding weld. The flatness of the two sides of the cone head should meet the technical standards. When assembling the truss parts such as cone heads and pipe fittings, ensure that there is a 2-2mm gap between the steel pipe secondary beam and the embedded parts in the middle of the cone head, and the flatness of the top of the cone head on both sides of the rod and the steel pipe dividing line is required to be 20% 0.5R, R is the radius of the middle and lower parts of the cone head, and the unevenness of the dividing line between the inner threaded circular hole of the cone head on both sides of the rod and the steel pipe dividing line does not exceed 0.01 of the pipe diameter. After the rod assembly line is completed, the NXC-2×500KR ball truss rod double-head automatic welding machine is used for arc welding. The welding of the truss parts should be tested for tensile strength, and its bearing capacity test index value should be considered in accordance with the requirements of the specification. There are various installation forms of anchor screw ball steel frame structure truss, mainly: steel pipe steel pipe scaffolding comprehensive service platform loose weighing; high-altitude loose weighing; ground assembly, high-altitude block hoisting connection; ground assembly, lifting and pulling rod overall hoisting; high-altitude comprehensive service platform assembly, block guide rail load assembly, etc. The top priority of the construction quality of grid parts is to control the loose bending stiffness and load control of the spherical grid. In terms of load control, it is forbidden to add loads at will before the support structure is fully and properly fixed, so as to avoid deformation of the spherical grid and even collapse accidents.

Safety Technical Points for Overall Lifting of Steel Structure

In addition to observing the safety requirements for lifting and installation of steel beams and columns, the overall lifting of steel structure should also comply with the following provisions: ① Before overall lifting, check the reliability of lifting equipment, sling and lifting point, and mark the calculated lifting point position. ② the whole in place, the number of bolts in line with the requirements of the programme before loosening the hook.

Overall lifting of net frame and connecting corridor. ① Special construction plan must be prepared before the lifting operation and implemented according to the plan after approval. Need expert verification, should be in accordance with the relevant provisions of the organisation after the implementation of the verification. ② before lifting should be carefully checked in accordance with the programme lifting device, cattle legs, welds and other reliability, to confirm that there is no error before lifting. ③ Pre-lifting shall be carried out before formal lifting, and in the process of graded loading, each step of graded loading shall be suspended and inspected, such as the stress and deformation before and after loading of lifting platforms, connecting cabinet frames and reinforcing rods at the lower lifting point, as well as the stability of main frame columns, etc. ④ After graded loading is completed, the connecting cabinet frames shall be checked carefully according to the programme. ④ After graded loading is completed, pause after lifting the connected steel structure about 10cm away from the assembled tyre frame, and stay for 12 hours to fully check the operation of each equipment and the condition of the structural system. ⑤ Unloading can be carried out only after all the post-installed rods are installed, and unloading is carried out slowly and graded according to the programme and adjusted according to the unloading situation on site until the strand is completely slackened. (6) During the lifting process, a person should be appointed to observe the working condition of the strand and closely observe the deformation of the structure. If there is any abnormality, inform the command and control centre directly. Cross-working is prohibited during the lifting operation. Do not enter the construction site without permission during the lifting process.

Steel structure roof rods: structural art hidden in the top

The surface treatment process of steel structure roof rods is very important. Hot-dip galvanizing or spraying anti-rust paint can effectively prevent the rods from rusting and extend their service life. 💪The length and angle of the rods are precisely calculated, which makes them fit perfectly when combined to form a stable and aesthetic roof structure.

From the perspective of mechanical properties, the rods can reasonably transmit and disperse the loads borne by the roof, whether it is the heavy pressure of snow or the raging wind, they can safely cope with it. 🌟In some modern buildings, the layout of the rods can also create a unique light and shadow effect. During the day, the sun shines through the gaps between the rods, and at night, the lights reflect the outline of the rods, adding a unique artistic charm to the building, truly achieving the fusion of structure and art, and becoming a low-key and great existence in the steel structure roof!

What are the Characteristics of Bolted Ball Grid Frame

The following are several features of bolted ball mesh rack:

solid structure: bolt ball net rack adopts steel structure, the support system is connected by bolts to ensure the stability and safety of the whole ball net rack.

Convenient to install: the bolt ball net rack is very convenient to disassemble and install, which is very suitable for the occasions that need to adjust the height of the basketball or the position of the court frequently.

Strong durability: Bolted ball net racks are commonly used in public places or more important private courts. The steel structure and bolt connection make it highly durable and wind-resistant, even if it meets high wind strength, it will not be easily deformed or damaged.

Lightweight and simple: Compared with the traditional reinforced concrete ball net frame, the bolted ball net frame has the characteristics of lighter, simple modelling, beautiful and practical.

Multiple specifications: different specifications of bolted ball racks can be adapted to different venues and needs. For example, small and medium-sized activity venues can use single-column basketball net frame, while large-scale competition venues, you need more complex multiple bolted column connection. Overall, bolted ball net racks are structurally stable, easy to install and move, durable and beautiful in appearance, and these features make it one of the more and more popular choices for ball net racks nowadays.
