Foundation bolts can be divided into fixed foot bolts, movable foundation bolts, expansion foundation bolts and sticky ground bolts. It is divided into: L type pre-embedded bolt, type 9 pre-buried bolt, u-type pre-buried bolt, weld embedded bolt, and ground plate embedded bolt.
Fixed foot bolts are also known as short ground bolts, which are watered with the foundation to hold equipment that has no strong vibration and impact.
Movable foundation bolts are also known as long foundation bolts, which are removable foundation bolts that are used for heavy mechanical equipment with strong vibration and impact.
The foundation bolt is often used for fixed and simple equipment or auxiliary equipment. The installation of the foundation bolt should meet the following requirements: the distance of the bolt center to the base edge is not less than 7 times the diameter of the foundation bolt; The base strength of mounting foundation bolts shall not be less than 10MPa; There shall be no cracks in the borehole, and the drill shall be prevented from colliding with the rebar and buried pipe in the foundation. The diameter and depth of the borehole should match the foundation bolt.
Sticky grounding bolt is a kind of foundation bolt used in recent years, and its method and requirement are same with the expansion foundation bolt. But when sticking, pay attention to clean the hole, and not damp.
