1.0 OBJECTIVE
Outline the method
statement for installation of shear stud for Station Concourse Level.
2.0 SCOPE
This method statement
shall be used for shear stud installation works for (your project name).
This method statement is
prepared based on current site condition; the method statement is subjected to
revise / amendment as if the project site condition changes.
The longitudinal shear
connection between the steel section and the concrete is provided by shear
connectors, which normally take the form of studs welded to the top of the
steel section. All connectors should be capable of resisting uplift forces
caused by the tendency for the slab to separate from the beam as it bends. In
the case of shear studs this is achieved by the head of the stud. Although
shear connectors ensure adequate fixing of the decking to the beam, they are
not needed simply to achieve this. They should only be used when it is desired
to achieve composite action between the slab and the steel beam.

6.0 WORK METHODOLOGY
I.
Before
installing the shear stud connector, make sure all the painting has been
removed and free from dust on top of the steel.
II.
Generator (4 ton) will be
placed on the ground and stud welding machine (400kg) will locate on top of the
hollow core slab.
III.
Mark all the shear stud
location and make sure check by consultant before start the installation shear
stud.
IV.
The working radius for the
installation shear stud is 18m.
V.
Make sure the shear stud gun
is perpendicular to the steel surface to ensure the shear stud is in 90 degree.
VI.
Once the shear stud is weld on
the steel surface, make sure the shear stud is fully welded.
VII.
Bend testing should be
conducted after the shear stud is weld on the steel beam. Practically 2-5
percent of the shear stud shall be tested and selected by consultant.
7.0 SAFETY
ISSUES
For safety reasons
there are precautions that need to be taken during installation.
·
Make daily check on all
lifting equipment.
·
Make daily checks on all
lifting slings.
·
Check that all access
equipment is in good condition, including scaffolding and ladders.
·
Check weather conditions,
strong winds are dangerous during erection and sheeting.
·
Check overhead electric lines
before moving in.
·
Check that all installer have
the correct personal safety equipment, helmet, safety shoes, safety harness and
etc.
·
Check electric cables for hand
tools, discard frayed or split cables.
·
Ensure permanent bracing and
flange stays are installed as work proceeds.
·
Ensure that high strength
bolts are used where indicated.
·
Maintain a clean and tidy.
Thus avoid material loss or accident.
·
Ensure that high strength
bolts are correctly tightened.
·
The site shall be kept clear
of unnecessary obstruction.
·
First aid kit boxes will be
provided at site office.
·
Workers to use safety harness
for work at height and provision of scaffolding for access.
Very good information!
