The function of cone head and sleeve

Cone head: When connecting thicker diameter steel pipes to the ball in a bolted ball steel structure grid, the pipe head is made into a cone to avoid collision (a ball usually connects 8 pipes). This type of prefabricated conical component welded to the steel pipe is called a cone head.

Sleeve: A hexagonal sleeve designed to tightly screw the bolts of the steel pipe head into the screw holes of the ball when connecting the steel pipe to the ball.

The cone head is a rotating thick walled shell that withstands tensile force from bolts or axisymmetric pressure from sleeves. The cone head and bolt are rotational axisymmetric bodies, and the constraint conditions between the cone head and the bolt are also axisymmetric.

The steel structure grid frame sleeve, commonly known as a plain nut, has a small hole on it that fits onto the high-strength bolt. The small hole is aligned with the keyway on the high-strength bolt and the top screw is screwed in. This way, when the plain nut (sleeve) is tightened with a wrench, the high-strength bolt inside the rod also rotates accordingly. It has the advantages of high strength, good corrosion resistance, good decorative aesthetics, and low price
