Lindapter

ICC-ES approved expansion bolts that require installation access to only one side of the Hollow Structural Section. All products in this range are quickly installed by inserting the fastener into a pre-drilled hole and tightening with standard hand tools. This faster alternative to welding or through-bolting enables contractors to reduce construction time and labor costs.

Overview

Hollo-Bolt (Hot Dip Galvanized) expansion bolts are ICC-ES and LARR approved for use in all Seismic Design Categories A through F, in compliance with the International and Los Angeles Building Codes. They require installation access to only one side of the Hollow Structural Section (HSS), and offer a faster alternative to welding or through-bolting, enabling contractors to reduce construction time and labor costs. Installation is quickly carried out by inserting into pre-drilled steel and tightening with a torque wrench. Also suitable for blind connections where access is available from one side only.

The larger 5⁄8" and 3⁄4" Hollo-Bolts are optimized for high strength structural connections and feature a unique High Clamping Force (HCF) mechanism for superior performance.

Features & Benefits

• Fast, cost saving installation from one side.
• For square, rectangular and circular hollow sections.
• High resistance to tensile and shear loads.
• High Clamping Force design (size 5⁄8" & 3⁄4").
• Low temperature tested to -50°F (carbon steel variants).
• Other head types available.
• Independently tested for dynamic load applications. Contact us for more details.
• New Hollo-Bolt plug-in tool available to download within Tekla Warehouse.

Properties

• Manufactured from mild steel or stainless steel grade 316.
• Available with zinc plated, hot dip galvanized or sheraplex finish.
• Reaction to fire: A1 (Steel)

Overview

The Type AAF girder clamp is the world’s first and only structural steel clamping system that is approved by ICC-ES for use in all Seismic Design Categories (A through F) and compliant with the International Building Code. It is used to achieve a fast steel-to-steel connection where high load capacities are present in either tensile, frictional or combined load directions. It features an innovative two-part design that incorporates a rocking washer to allow the clamp to self-adjust to suit a range of flange thicknesses. Manufactured from low temperature SG iron with a hot dip galvanized finish to provide high performance and anti-corrosion protection in cold environments down to -76°F.

Features & Benefits

• High slip resistance for tensile, frictional and combined load applications.
• Self-adjusts to suit flange thicknesses 3⁄16" - 19⁄16" (size 3⁄4").
• Safe working loads apply in temperatures as low as -76°F.
• Suitable for parallel and tapered flanges up to 10°.
• The tail spans slotted clearance holes.
• Lindapter recommends the use of DTI Washers when using A325 or A490 structural bolts with Type AAF.
• Independently tested for dynamic load applications. Contact us for more details.

Packing Pieces

Packing pieces are available to increase the clamping range. Download datasheet for further information www.lindapter.com

Location & End Plates

Location plates are required when securing two sections together with clamps attached to the upper and lower sections with both clamps directly opposing each other. The plate is positioned between the two sections to hold the bolts at the correct centers and should be fabricated to the dimensions shown in the datasheet.

End Plates should be used when clamps are attached to the supporting section only. The End Plate holds the bolts at the correct centers and should be fabricated to the dimensions shown in the datasheet.

Properties

• Manufactured from low temperature SG iron to BS EN 1563.
• Available with hot dip galvanized finish.
• Reaction to fire: A1 (Steel)

Overview

The Type AF girder clamp is the world’s first and only structural steel clamping system that is approved by ICC-ES for use in all Seismic Design Categories (A through F) and compliant with the International Building Code. The Type AF girder clamp is used to achieve a fast steel-to-steel connection where high load capacities are present in either tensile, frictional or combined load directions. It has a recessed top to hold the bolt head captive while the nut and washer are tightened down using only one tool, alternatively use a Type AFW washer to convert the recess to a flat top. The skirt on the underside of the clamp abuts the edge of the beam flange and prevents the clamp rotating during installation. Manufactured from SG iron with a hot dip galvanized finish to provide high performance and anti-corrosion protection.

Features & Benefits

• High slip resistance for tensile, frictional and combined load applications.
• 15,736lbs static slip resistance or 56,200lbs tensile (4 x A490 bolt configuration, size 1").
• Recess holds the bolt head captive (Grd. 5 bolts, sizes 1⁄2" - 3⁄4").
• Suitable for parallel and tapered flanges up to 10°.
• The tail spans slotted clearance holes.
• Lindapter recommends the use of DTI Washers when using A325 or A490 structural bolts with Type AF.
• Independently tested for dynamic load applications. Contact us for more details.

Tail Lengths & Packing Pieces

The clamp is available in two tail lengths, Short or Medium, and can be used with Lindapter packing pieces to increase the clamping range. Choose the correct combination of tail length and packing pieces to suit a specific flange thickness. Download datasheet for selection table.
