Lindapter clamping systems provide a fast, cost-effective alternative to on-site drilling or welding by helping to reduce installation time and labour costs. High strength, permanent (or temporary) connections are achieved by simply clamping two steel sections together.

Girder Clamps

1) Bring the location plate and lower beam into position below the upper beam.2) Fit bolts with two Lindapter clamps, any packings required, a nut and a washer.3) Using a torque wrench, simply tighten each bolt to the recommended torque.

The original configuration is designed to secure steel sections and resist tensile loading. It features a pre-drilled location plate that is placed between the beams to locate the four bolts. Each bolt has two Lindapter components to clamp the flange immediately above and below the plate. For thick beams, a packing piece is required to raise the height of the clamps to enable the product to sit correctly on the beam.

Standard: Beam-to-beam (tensile loading)

This configuration utilises a High Slip Resistance (HSR) clamp per bolt to achieve a secure connection to vertical columns. An end plate is pre-fabricated to the section that will be joined to the column. The purpose of this plate is to locate the bolts and provide a fastening position for the Lindapter clamps.

High Slip: Beam-to-column (slip resistance)

A fabricated assembly, optimised with Lindapter’s adjustable HSR clamps to resist both tensile loading and slip. This solution adjusts to fit a wide range of flange thicknesses for added convenience. Lindapter can design and supply the entire assembly to suit individual applications.

Adjustable: Inclined beam-to-beam (combined loading)

Quick and easy to install

1) Align pre-drilled fixture and section then insert the Hollo-Bolt. 2) Grip the Hollo-Bolt collar with an open ended spanner. 3) Using a calibrated torque wrench, tighten central bolt to recommended torque.

HIGH CLAMPING

FORCE

A typical connection is made by inserting the Hollo-Bolt into the pre-drilled holes of the fixture and hollow section. As the bolt head is tightened, the cone is pulled up the bolt thread, causing the sleeve to expand until the cone locks the sleeve against the hollow section’s inner wall.

At full tightening torque, clamping force is established between the fixture and the steel section to form a secure connection. Once installed only the head and collar are visible.

Standard Hollo-Bolt (M8-M12)

Working closely with Structural Engineers and Steel Fabricators, Lindapter identified the need for the larger M16 and M20 Hollo-Bolts to have an increased clamping force suitable for higher strength structural connections. This led to Lindapter’s invention of the High Clamping Force (HCF) design.

The Hollo-Bolt HCF features a patented mechanism that allows the product to produce a typical clamping force over three times higher than the same sized product without the mechanism.

Hollo-Bolt HCF (M16-M20)

Countersunk, Hexagonal and Flush Fit head types are available off-the-shelf. Lindapter can also design customised solutions, the Security Button Head for example was developed for use in high security facilities.

The original expansion bolt for structural steel requires access from one side only to quickly connect steel sections to pre-drilled Structural Hollow Section (SHS). Hollo-Bolts are a faster alternative to welding or through-bolting, reducing construction time and labour costs.

Hollo-Bolt®

For securing rails or crane lines in low speed applications such as ground track, elevated rail and overhead gantries. These fixings are used in environments including train maintenance depots, industrial facilities, water treatment plants, dam/dockside cranes, automated warehouses and power stations.

Rail Fixings

Pictured: Type HD provides lateral adjustability to allow quick and precise rail alignment.

Lindapter lifting points are used in a variety of industries to support the lifting and rigging of equipment. Applications vary from suspending overhead light duty audio-visual kit in theatres to lifting heavy drilling risers onto offshore platforms. Lindapter can design bespoke lifting points to your specific application requirements.

Lifting Points

Pictured: The Type ALP self-adjusts to suit various beam sizes and lift orientations.

Innovative fixings for securing steel flooring to the supporting steelwork without the need for on-site drilling or welding. Access to the underside is not required, eliminating the need for costly scaffolding or elevated floors. Installation can be carried out quickly and safely from above by one person.

Floor Fixings

Pictured: Grate-Fast® quickly connects open bar grating from above, helping to reduce costs.

Decking Fixings

These easy-to-install connections are designed to suspend building services from structural or secondary beams. Typical applications include HVAC equipment support, pipe work, fire protection and sprinkler systems. Adjustable to allow a fast and precise alignment of building services.

Support Fixings

High quality, cost effective connections for securing building services. Designed to fit inside the dovetail re-entrant channels of popular composite decking profiles, Lindapter’s fixings provide a zero-impact method that avoids delamination and damage to the decking.

Pictured: Type F3 has a large clamping range to suit a wide range of flange thicknesses.

Pictured: Type TR60 consists of a wedge and locking plate and is quick to install.
