Rigid Tieback Anchors are ideal for installing insulation on roofs and are available in a wide variety of types. They come with a 20-inch diameter galvanized steel tube for superior strength and durability. This anchor is safe and suitable for most roof types, but should be installed by a trained individual who follows the manufacturer’s instructions. There are several online shops available from where you can purchase these rigid tieback anchors, such as Safeguard Industries.
Helical tiebacks
A helical tieback anchor is a type of structural tieback anchor. It is a type of tieback that is attached to the underlying structure by a threaded bar. Unlike grouted tendon tiebacks, which require drilling and grouting before proof testing, helical tiebacks can be loaded immediately. This type of tieback is also highly adjustable, allowing the length of the anchor and the helix bearing area to be modified in the field.
A helical tieback anchor is pre-engineered, making installation easy and cost-effective. These anchors can support up to 200,000 pounds of weight. They can be installed with common rotary drilling equipment. Installing torque is a key factor in determining the anchor’s holding capacity.
Skyline
Skyline rigid tieback anchors are designed for rooftop and facade applications, providing safe and practical anchor points. These systems are engineered to meet or exceed OSHA standards and resist fracture, pullout, and permanent deformation. The company’s manufacturing locations across the United States and Canada allow it to serve the geotechnical needs of a wide range of customers. Its tieback anchors and related hardware have been used in thousands of applications worldwide.
When selecting skyline anchors, it is important to consider the weight and geometry of the cable. Tensile force is affected by the cable geometry and the force applied. Sag is an important factor, and the longer the line between the supports, the lower the tensile force. This reduces the risk of catastrophic anchor failures, and also helps prevent tipping of yarding towers.
Magnacore
Tiebacks are horizontal rods used for reinforcing retaining walls and foundations. Once anchored, tiebacks can be lengthened or shortened to accommodate the specific application. The Intech Anchoring systems feature hollow steel rods that can be shaped to meet any length requirement. Combined with the use of Magnacore, these anchors stabilize foundations, slopes, and structures at shallow depths.
This system provides practical and safe anchorage points for roof and facade work. Its design exceeds OSHA standards and is engineered to resist pullout, fracture, and permanent deformation. It also offers rapid production for custom anchor projects. Thousands of installations worldwide have proven its effectiveness.
Sesco
Sesco Safety Tie Back Anchors are designed to provide safe anchorage points for roof and facade maintenance. These anchors are engineered to meet and exceed the standards required by OSHA. They resist pullout, fracture, and permanent deformation. They are available in different styles, including weld-on, epoxy-adhesive, and bolt-on. Thousands of applications have shown that these anchors provide a safe working environment for building maintenance workers.
Sesco offers a variety of tieback anchors to meet the needs of many different construction projects. They can be used for retaining walls, foundation walls, and earth shoring walls. These anchors are designed for limited access areas and are available in a variety of sizes.
Soilscrews
Soilscrews are passive soil reinforcement products that provide support for tieback walls. They are typically installed four to eight feet apart and are of a uniform length, ranging from seventy to a hundred percent of the wall’s height. Compared to tieback anchors, soil screws offer greater flexibility when it comes to anchor placement.
Soilscrews can be a great solution for shoring up loose soils. Depending on the soil, a single soil screw can support two to five feet of soil weight. These anchors are made with helical plates that have a standard three-inch pitch and are installed at a depth that is practical and safe. Since these anchors screw into the ground, the load is transferred instantly per bearing plate.
In a recent project, a cardboard manufacturer needed to install a conveyer pit inside its facility. The pit was 140 feet long, 22 feet wide, and twelve feet deep, totaling more than 3,000 square feet. This pit had to be installed in an existing building that had limited headroom, and the pit was surrounded by structural columns. For this project, CHANCE chose the soil screw system for its speed of installation, flexibility, and ability to work around existing structural columns.
