A dynamic anchor is a load-bearing industrial seal used to secure structural elements like plant or machinery to concrete. One end is inserted into the concrete while the other end is attached to support the structure. In addition, it strengthens these structures to assist them in resisting various dynamic loads or seismic movements. A dynamic anchor is made from zinc-plated carbon steel or stainless steel. These anchors are important to today’s civil engineering industry as the necessity for structural safety is higher than ever before.
How do they work?
Dynamic anchors are occasionally embedded directly into the concrete during the pouring process. However, they can be post installed afterwards by drilling into an already compact concrete structure. Post-installation of anchors can be done in two ways, chemical, and mechanical installation. Post-installation is most appropriate for cracked or non-cracked concrete. Mechanical anchors like the dynamic undercut anchor function by using a widened aperture within a drilled hole to make an interlock between the anchor and the concrete. This secures the structure and makes it more stable. Chemical anchors, however, need the use of a mortar-based sealant inserted into the drilled hole before the anchor is placed. As soon as the mortar is laid down, it establishes a secure bond between the hole and the anchor. Enlarging the diameter and depth of the drilled hole extends and heightens the load-bearing power of the anchor. This allowance to adjust the diameter and depth of the drill hole makes chemical anchors stronger compared to mechanical anchors. However, the choice on which anchor to use depends on the project at hand
How do they resist seismic loads?
Seismic loads are the forces a structure encounters during a seismic occurrence like an earthquake. The seismic occurrences have different time spans and intensities. As a result, most structures within the affected area are at risk of severe destruction and possible caving in. Using anchors manufactured to stand against seismic loads significantly decrease the potential of structural destruction and collapse. Its numerous advantages assure public safety and safeguard human life.
