Specification and quantity of welding studs for steel decks

Many people have many misunderstandings about the specifications and use of studs. This article explains the specifications and quantities of studs.

The specification of welding studs

SOLIDECK believes that the specification of welding studs for steel floor decks mainly depends on the distance of the plate span.

Specifications: plate span < 3m, the diameter of the stud is 13mm, 16mm. 3m≤span ≤6m, the diameter of the stud is 16mm and 19mm. Plate span>6m, the diameter of the stud is 19mm. In general design drawings, the diameter of the stud is 16mm and 19mm.

The amount of welding studs

The amount of welding studs used for is related to the spacing of welding studs and the flange width of the beam.

In the direction perpendicular to the plate rib, the maximum distance between stud anchors is 350mm, and each piece of steel floor deckhas at least 3 ends. 15mm fusion welding is used in the direction parallel to the plate rib, and the maximum distance is 600mm. Bolt anchoring can also be used.

In general design drawings, in the direction perpendicular to the plate rib, the distance between the bolts and anchors is 200mm, and the direction parallel to the plate rib adopts 15mm fusion welding, and the maximum distance is 600mm.

If the width of the steel beam flange is less than 200, use a single row of studs. If 200≤the width of the steel beam flange is less than or equal to 350, use double-row studs. If the width of the steel beam flange is greater than 350, use three rows of studs.

Therefore, according to the specification and the description of the studs in the project drawings, it is very simple to calculate the specifications of the studs and the amount of the studs.
