![]() The National Concrete Masonary Association recommends a rule of thumb for the length of a fastener embedded into concrete. For loads fastened on the edge, resting on the ground, smaller diameter bolts can be sufficient. For loads that attach overhead to a wall, specify stronger bolts. A 1/2″ anchor set with a minimum embedment of 2″ produces a stronger hold than a 1/ 4″ anchor with a minimum embedment of 1″.Īnother thing to consider is where the load that the anchor bolts will be holding will be fastened to the concrete. Also, the best holding value occurs in deeply embedded anchors within very hard concrete. In general, as diameter increases, load and carrying power also increases. For maximum safety, specify the strongest, largest, and deepest bolts. The anchor bolt is the weakest point in the concrete structure and therefore its strength and its diameter depend on the supported weight. You must be aware of the total load that the anchor may hold. When choosing the right fastener for the job, you will want one strong enough to hold the strain of the load but without compromising on the stability of the complete structure. This occurs via a mechanical interference fit or via the use of a chemical anchoring system. In such cases, drill-in-place anchors secure equipment to the slab. However, civil contractors don’t always know the required fastening location due to late arriving or not yet determined equipment. Generally, the preferred method of securing involves directly casting them into the concrete prior to curing. The selection of the right fastener depends on the base material to which the object anchors. Some anchor bolts are designed for concrete, while others for cement or masonry work. First, it is important to determine the size of the hole for the anchor bolt and its length. There are many issues to consider when selecting an anchor bolt to fasten an object to the concrete structure. That is why it is essential to select the right anchor bolts for your application. When you connect a piece of equipment to concrete, it should hold for a lifetime. ![]() DESIGN OF HEADED ANCHOR BOLTS PDF ISOThe minimum coating thickness is 55 µm, which fulfils environmental class C3 of standard EN ISO 9223:2012.Swedge Indentions, Courtesy: TSA Manufacturing Selecting the Right Anchor Bolt The method is suitable for HPM ® and PPM ® Anchor Bolts. Hot-Dip Galvanized (according to EN ISO 1461) anchor bolts are completely dipped into galvanized material. ECO Galvanizing is available for Anchor Bolt models HPM ® 24 - 39 and PPM ® 30 - 52. The coating fulfils environmental class C3 of standard EN ISO 9223:2012. The minimum coating thickness is 100 µm, which corresponds to the performance of hot-dip galvanizing. The coating method is thermally sprayed zinc coating, according to EN ISO 2063. Peikko’s ECO Galvanizing is a cost-effective and ecological surface coating which allows anchor bolts to be galvanized partly or completely. If other type of protection against corrosion is needed, please contact your local Peikko sales office for more information. Standard coating options for anchor bolts are described below. Anchor bolts are available with alternative protective coatings. PPL Anchor Bolt Installation Templates are provided to ensure easy and correct installation of the anchor bolts in castings and foundations.Īnchor bolts are often used in various applications, from dry indoor conditions to harsh industrial conditions where additional protection against steel corrosion is needed. The long anchor bolts transfer compression and tension forces through the rib bond of ribbed bars, while the short anchor bolts transfer the forces through the combination of headed studs and rib bond. Short anchors (type L) with headed studs, which are used for anchoring into foundations.Long anchors (type P), which are used for splices.PPM ® High-Strength Anchor Bolts are used with BOLDA ® Column Shoes, SUMO ® Wall Shoes or even with steel columns and machine fixings. There are two main anchor types: PPM ® High-Strength Anchor Bolts transfer tension, compression and shear forces to the reinforced concrete base structure (e.g., foundations). The product range is suitable for loading conditions where heavy-duty connections are needed. ![]() High-strength steel PPM ® High-Strength Anchor Bolts are used to anchor concrete or steel structures or machinery into concrete base structures in demanding anchoring applications. ![]()
