Tie Rods and Tiebacks.

Types of concrete anchors. Manta Ray. Male Type Anchors - A stud-type anchor that is inserted directly into a predrilled hole in the concrete. Heres a little bit more about these materials and their common uses.

Concrete anchors types vary and include concrete screws hammer-set anchors lag shields lead screw anchors plastic wall plugs anchor bolts and more. Wind Turbine Foundation Anchors. Chemical Anchors - Epoxy and Hybrid Adhesives Mechanical Concrete Anchors Cast-in Anchor Channel Cast-In Anchors.

In prestressed concrete structures prestress is introduced by stretching steel wire and anchoring them against concrete. The first is the self-drilled fastener which works by cutting threads into the concretebrick or block. These type of anchors transfer the loads from the bolts to the concrete base through the adhesive bond between them.

There are many different types of materials anchors can be embedded into but the most commonly used ones are drywall plastertile concrete block and brick. These types of concrete anchors would be the Tapcon flat or round head sleeve anchors or any female type anchors where a specific bolt head can be chosen to be inserted into the anchor. Female Type Anchors - A female anchor is.

Designed for fastening to concrete brick and block a standard lag type screw is used to expand the concrete lag shield anchor. Therefore the prestressing systems should comprise essentially a method of stretching the steel and a method of anchoring it to the concrete. Different systems are adopted for pre-tensioning and post tensioning.

These can be used to mount electrical junction boxes furring strips HVAC strapping exterior insulation systems plywood backer boards etc. No setting tools are required. When dealing with male anchors hole size is equal to anchor size with the exception of the Tapcon screw.

Hilti engineering creates anchor options that deliver maximum productivity performance and reliability in any application. Grade 75 Grade 80. Masonry and concrete anchor types are considered light-duty medium-duty or heavy-duty based on how much weight they can support.

The lag shield anchor comes in five diameters 14 516 38 12 58 and 34 which refers to the internal threads or the diameter of the lag screw. Drop-in anchor machine screw anchor double expansion single expansion anchors. S-7 Reusable Concrete Anchor.

These female type anchors would include the. These are a common type of post-installed anchors inserted into the hardened concrete with an anchor hole diameter less than 15 times the bolt diameter. Chemical and mechanical anchors for concrete and masonry applications.

Some common terms for these anchor bolts are wedge bolts Titen anchors high strength anchors LDT or THD anchorsThey are installed by drilling a pilot hole and driving in the screwbolt. LoadWeight Capabilities of the Wall Anchor. A relatively new type of anchor bolt is the screw in type.

No spotting of the hole is required and oftentimes the hole can be drilled through the fixture and into the base material. These are basically large concrete screws like Tapcons. Grout Bonded Concrete Anchors.
