Anchor bolts are anchoring components that are anchored to the base material by connecting parts, divided into mechanical anchors and chemical anchors, which are derived from JGJ145-2013 "post anchorage technical regulations of concrete structures". The material of anchor bolt is divided into reinforced concrete, prestressed concrete or plain concrete component. It cannot be used as anchorage base material, including freeze-thaw damaged concrete, corroded damaged concrete, severely damaged concrete, non-compact concrete. Chemical anchor is a new type of metal fastening material composed of chemical agents and metal rods. The chemical anchor is a new type of anchor bolt, which is a special chemical binder, which is fixed in the drilling of the concrete base material to achieve the fixed anchorage composite.
Chemical anchors are divided into general chemical anchors and special inverted cone chemical anchors. The product features include anti fatigue, anti-aging, corrosion resistance, no creep, strong bonding force, high pulling force and the same effect as embedding. It has a wide range of use temperatures ranging from 10 to 40 degrees. It is suitable for small space, margin and narrow space. It is suitable for all kinds of substrates, concrete, rock disc, aluminum, etc. Non-expansive chemical bonding, no damage to the substrate; Convenient construction, environmental protection. Application: it can be used for fixing glass, stone and all kinds of composite curtain walls; fixing machine equipment; connecting and fixing steel structure with concrete structure, chemical pipe, equipment pipeline, crane track and other building equipment. Mechanical anchor bolt is a kind of anchor bolt formed by the friction between anchor bolt and anchor hole. According to its working principle, it can be divided into two types: enlarged anchor bolt and expansion anchor bolt. According to the "expansive and bottom building anchor bolt for concrete", the material of mechanical anchor is suitable for carbon steel, alloy steel, stainless steel or high anti-corrosion stainless steel, which is selected according to the requirements of environmental conditions and durability.
