Price of grid cone heads - What are grid cone heads

The conical head is a component used in the bolt ball steel grid structure. It is welded to the top of the steel pipe by electric welding. The extruder screw of the high-strength bolt passes through the circular hole at the bottom and is screwed into the bolt ball. The screw cap is inside the conical head and has the same function as the "connecting plate". When the diameter of the steel pipe is small, the "connecting plate" is selected. When the diameter of the steel pipe is large, it is to prevent the steel pipes on the same bolt ball from colliding. Select "conical head". Price of grid structure cone heads.

The edge welds on both sides of the steel pipe and the conical head belong to the connection welds and are specified to be of the same strength as the butt welds. In the laser welding processing of spherical grid structure members, multi-head automatic welding machines and the fully automatic laser cutting and profile CNC lathes that are matched with them are selected. The welding method adopts carbon dioxide gas shielded welding. The main parameters and welding posture of the electric welding are fully computer-controlled automatically. Therefore, the electric welding quality of spherical grid structure members has obtained stable and reliable 倮 certificates. On the basis of the actual operation workers' self-inspection of the weld quality in terms of appearance, the professional quality inspectors take 10% samples of the welds on both sides of the rods produced by each shift for appearance and geometric specification inspection, and use the "Code for Construction and Acceptance of Steel Structures" (GB50205-95) as the basis for appraisal. For the tensile members, at least 5% (at least 5 pieces) of the finished members should be extracted according to their specifications and models for ultrasonic flaw detection inspection of the welds. The quality of the welds must comply with the Grade II weld standards stipulated in the "Steel Structure Engineering Quality Inspection and Evaluation Standard" (GB50221-95). Take the members with poor load-bearing capacity. Take 300 members of the same specification and model as a batch. Each time, take 3 members as a group for random sampling inspection. Conduct a destructive test on a tensile testing machine. If the compressive strength performance K is ≥2, a test report will be issued by the laboratory. Key detection instrument: CTS-26 ultrasonic flaw detector; 100T tensile testing machine. Price of grid structure cone heads.

The processing of the grid structure is very simple and easy: just weld the anchor bolts, connecting plates/conical heads and members together by electric welding. Subsequently, the finished bolt balls are produced and processed in accordance with the production and processing drawing of the bolt balls. Just spray and pack it.

The cone head is cut from round steel. Before the cone head blank is forged, it must not undergo defects such as burning and cracking. After forging, the quenching process is specified to remove the oxide scale. Price of grid structure cone heads.
