Product description:
·Consisting of a screw, thrust sleeve, flat pad, spring pad and nut. Two tubes, expanded twice, with three embossed lines in the middle expansion position for a stronger anchorage.Application:
·Curtain Wall Embedded Parts Fixing
·Curtain wall keel fixingMaterial:
·Grade 4.8 steel, Grade 5.8 steel, Grade 8.8 steel,Stainless steel 304(A2-70)/316(A4-80)
·Surface treatment (except for stainless steel):
Electro-galvanised (zinc layer thickness >5um), Used inNormal environment
Hot-dip galvanised (zinc layer thickness >45um), for corrosive environmentsSubstrate:
·Non-cracked concrete/cracked concrete
·Natural stoneAdvantages:
·Stable and excellent anchorage performance under high loads, vibration loads and shock loads performance
·Mechanical locking, no need to wait for curing time after installation in place, improving work efficiencyOperation process
1、 Use straight hole drill bit to drill the corresponding diameter and depth of the empty.
2、 Use the dust blower to blow dust into the hole until no dust overflows from the hole.
3、 Use hammer drill to hammer down the self-expanding bottom anchor bolt to make the bottom expand to complete the anchoring.
