Shear Connector Studs are designed to tie the concrete slab to the steel beams and to resist shear loadings between the concrete slab and steel beam in composite construction. This enables us to load up to 1000 kg/m2 instead of the usual load which is much less. The procedure saves time and therefore money as well due to its simplicity.
Each weld cycle depends on the diameter of the fastener and the material being joined and takes up to only 1 second. Welding currents range from 240 to 3000 amps
Tensile strength Rm >= 450 N/mm2
Yield strength Rel >= 350 N/mm2
Elongation A5 >=15%
Notch impact 27J bei -20
The Shear Stud is made of steel and it is delivered with a ceramic ferrule to ensure a good connection of the Stud with the beam.The shear Studs are available in different lengths and diameters . The length of the Stud will be reduced by approximately 5mm during the welding process. All Shear Studs are supplied with ferrules. The ferrules are made of clay and able to withstand heat shock as well as high temperatures without melting or breaking.
The shear connection of a composite beam comprises five elements that can all influence behaviour. They include the shear stud connectors, profiled steel sheeting(steel deck) ,
slab reinforcement (rebar or steel mesh) , concrete slab and steel beam top flange.
In such design the shear Stud connects the steel deck to the concrete slab.
Shear Stud Connectors are the most important element in Composite Beam design securing the concrete to steel structural components. Shear Stus Connectors resist shear forces and increase shear loading capacity in steel buildings,bridges,
Design of the shear stud connector is very important because
1- it affects the choice of a suitable ultimate strength design method for the composite beam
2-The economics and speed of construction
3-The stability of the steel beam
4-The safety of steel beam against collapsing
The ultimate strength of most composite beams is governed by shear stud connector shear capacity
Shear stud manufactured in our factory are regularly weld tested .We have our own welding machines in house and customers are welcome to inspect the welding process
Shear studs are also mechanically tested. Bending tests are performed for each order after welding. Shear studs are also tested for elongation and tensile streghth using our own testing equipment
Raw materials are carefully selected to achieve the necessary mechanical conditions laid out in ISO 13918 standard
Packaging of shear studs can be in carton boxes which are easy to carry or in metal drums .Choice of packaging is upto to the customers' preference.
Inspection certificate : Top quality properties can be documented by test report 2.2 or inspection certificate 3.1 or 3.2 (EN 10204)
