Rear-reaming anchor bolts are a general term for a type of fasteners that are anchored by non-chemical bonding methods. Conventional mechanical anchor bolts used in construction include rear reaming anchor bolts, heavy-duty anchor bolts, anchoring anchor bolts and multiple anchor bolts. Grade expansion bolts. Back hinge bolts are also known as back cut anchors, die hinge anchors and back cut anchors. The biggest difference from other mechanical anchors is that the bottom of the anchor rod is completely embedded with back anchor technology, so as to achieve the effect of mechanical locking. Unlike rear expansion bolts, multi-stage expansion bolts, heavy duty bolts and anchor bolts are installed through straight holes. The installation principle is to form friction with the wall to achieve anchoring. The types and principles of mechanical anchor bolts are briefly introduced.
Chemical anchor bolts are a new type of metal fasteners, mainly composed of chemical agents and metal rods. It can be effectively used in the installation of rear components in curtain wall and marble dry-hanging operations, and can also be used for equipment installation. The chemical anchor bolt basically cooperates with the concrete foundation to carry the weight and load of the machine, mainly to ensure the machine. For stable work, the materials of anchor bolts used in concrete structures are mainly carbon steel, stainless steel or alloy steel. The appropriate type should be selected according to different environmental and durability requirements.
