Sealing threaded rods in masonry allows the attachment of very heavy parts.
The threaded rods are in metal bars to be cut according to the desired length. Their diameter is chosen according to the type of attachment or anchoring to achieve. In general, a chemical sealing kit consisting of honeycomb plugs (sieves) and a resin-hardener mixture in a gun-injection cartridge is used.
The setting time varies from 30 minutes to 2 hours depending on the ambient temperature.
Measure and mark in pencil the location of the threaded rod to be integrated into the frame.
The process remains the same for hanging on a wall or anchoring on the ground.
Drill a hole using a drill, using a concrete drill corresponding to the size of the chemical peg to be inserted.
Unpack the chemical sealing kit.
Screw the plastic cannula into the end of the cartridge and place the assembly into the gun.
Insert the chemical peg into the hole.
It may be necessary to add the reduction ring provided in the kit at the flange.
Slide the cannula into the hole and inject the resin and hardener mixture through the gun.
Fill the cavity until slightly overflowing.
Slide the threaded rod into the still fresh product.
Allow it to protrude sufficiently far from the cavity and then cut it again.
Respect the setting time.
The chemical anchor is used to suspend heavy loads up to 700kg, in solid or hollow materials.
Sealing the suspension hook is as for a threaded rod.
Nevertheless, his thread is often much thicker. This is why the chemical peg can do without the addition of a reduction ring.
