Brief Description Of Anchor Bolts

Anchor bolts (anchors) for external insulation are composed of expansion pieces and expansion sleeves, or only expansion sleeves. They are mechanical fasteners that connect the insulation system to the base wall by relying on the friction generated by expansion or mechanical locking.
In the installation of external wall insulation panels, in order to make the system safer, various types of anchor bolts (anchors), metal brackets (or angle steel metal brackets) or connectors are often used to assist in strengthening according to the material or finish type of the insulation board.
Anchor bolts are special mechanical fasteners used to fix hot-dip galvanized welded mesh, alkali-resistant glass fiber mesh or insulation board, and fire isolation belts to the base wall.
Anchor bolts should be made of steel grades with good plasticity such as Q235 steel and Q345 steel, and high-strength steel should not be used. Anchor bolts are non-standard parts, and because of their large diameter, they are often made of unprocessed round steel similar to C-grade bolts, and are not processed by high-precision lathes. Anchor bolts for exposed column feet often use double nuts to prevent loosening.
