Un catálogo completo de productos e información para los sistemas de anclaje, sujeción y restauración para concreto y mampostería. Earth retention systems such as concrete retaining walls, soldier pile and timber lagging, and sheet piling. Type 304 stainless steel (Type 316 available by special order — contact Simpson Strong-Tie for details). Seismic loading restraint for foundation uplift and lateral support systems. Anchors are used in tension applications and piles are used in compression applications. As it is driven, the fins of the tie undercut the masonry to provide an expansion-free anchorage that will withstand tension and compression loads. Helical anchors can also be used in some circumstances and can be more economical. Electric utility companies began to use screw piles for tie down anchors on transmission towers and for guy wires on utility poles. Diseñado para dar información útil en la gestión de químicos en el lugar de trabajo; p.ej. Load is transferred from the shaft to the soil through these bearing plates. Patch the hole in the façade with a matching masonry hanger. We use cookies on this site to enhance your user experience. Helical tiebacks are often used to stabilize existing earth retaining structures that have experienced excessive movement; i.e., walls that are cracked, leaning and/or bowing. Helical Ties. Embedded in concrete in use bi-directional force. The Heli-Tie helical wall tie is a stainless-steel tie used to anchor building façades to structural members or to stabilize brick walls. A product guide for Simpson Strong-Tie® providing information on adhesives, mechanical anchors, direct fastening, carbide drill bits, and concrete restoration products, for concrete and masonry. You can also view product information related to the category: Drill should be in rotation-only mode when drilling into soft masonry or into hollow backing material. With the SDS-plus rotohammer in hammer mode, drive the tie until the tip of the installation tool enters the exterior surface of the masonry and countersinks the tie below the surface. Helical or Helix Anchors We recently discontinued selling Helix anchors and the reason is quite simple: Customers reported numerous issues with helical-style anchors.

Prévu pour fournir de l’information sur la gestion des produits chimiques au travail comme propriétés physiques, dangers, mesures de protection et précautions de manipulation, stockage et transport. 3,000 # and 4,000 # chain with primary/slack hook and clamp/bolt. Guía de productos para Simpson Strong-Tie® con información sobre anclajes adhesivos, anclajes mecánicos, sujeción directa, brocas de carburo y productos para restauración para concreto y mampostería. Available in any length, material, diameter and finish. The helical design allows the tie to be driven quickly and easily into a predrilled pilot hole (or embedded into mortar joints in new construction) to provide a mechanical connection between a masonry façade and its backup material. Provides an inconspicuous repair that preserves the appearance of the building. The torque correlation method is commonly used to verify capacity during tieback installation. The end of the shaft is typically coupled to an adaptor that transitions the shaft to threaded rod. The Heli-Tie wall tie is installed into a predrilled hole using a proprietary setting tool with an SDS-plus® shank rotohammer to drive and countersink the tie. Helix plates are typically limited to the lead section or the lead and first extension of the tieback. for small aircraft and boats to 40,000 lbs for large multi-engine aircraft and large marine craft. Position blue end of the Heli-Tie™ fastener in the installation tool and insert the tie into the pilot hole. A flier providing product and installation information on the Heli-Tie™ helical wall and stitching ties. The helical design allows the tie to be driven quickly and easily into a predrilled pilot hole (or embedded into mortar joints in new construction) to provide a mechanical connection between a masonry façade and its backup material. Larger core diameter provides higher torsional capacity, resulting in less deflection due to “uncoiling” under load. Drill pilot hole through the façade material and into the backup material to the specified embedment depth + 1" using appropriate drill bit(s) in the chart below.

Pull testing helical tieback for pullout strength. Fractionally sized anchor — no metric drill bits required. The helix plate design depends on the soil strength parameters and the required working capacity. Helical anchors/tiebacks are commonly used in tension applications to provide either temporary or permanent lateral or tie-down support for applications including: Helical tiebacks are manufactured with similar helix plate sizes and helix spacing as helical piles installed vertically to support foundation loads. 2019–2021 Guía de productos - Anclaje, sistemas de sujeción y soluciones de restauración para concreto y mampostería. Anchoring, Fastening and Restoration Systems for Concrete and Masonry.
