Girder Clamp, connect beams without welding or drilling

no welding

no drilling

connection is fast and easy

The Girder Clamp is a rigid assembly for securing secondary steelwork to structural members.

Because there is no drilling, the integrity of the steelwork remains intact.

There is no welding so the connection is speedy, simple and adjustable if required.

The Girder Clamp is a rigid assembly for securing secondary steelwork to structural members. Because there is no drilling, the integrity of the steelwork remains intact. There is no welding so the connection is speedy, simple and adjustable if required.

Each Girder Clamp comprises: two adapters per bolt; nuts; washers and a pre-drilled location plate. By altering the location plate dimensions a Girder Clamp can be supplied to accommodate any size or type of steelwork. Similarly, it can be varied to cope with differences in height between primary and secondary steelwork and/or angular displacement between the two members.

On receipt of the relevant details of an application we will supply complete Girder Clamp assemblies, which include specifically designed location plates and all necessary components. When installed according to our recommendations the Lindapter Girder Clamp carries a guarantee of performance.

When Lindapter Girder Clamps have been specified, the complete connections are delivered ready for immediate installation according to the assembly diagram supplied for each type.

Finish- Lindapter - Electro-Galvanised; Location plate/bolts - as required.

§ Special conditions may apply. See Loads and Specifications.

Data shown is for a 90° crossover in a tensile load condition.

All loads are based on the recommended Safety Factor of 5.

Use of any lower Safety Factor is at the customer's discretion.

Important Note:

The location plate is an integral part of the Lindapter Girder Clamp. Its use is essential, to hold the bolts close to the steelwork and to support the tails of each Lindapter.

When ordering girder clamps the following details are required:

1. Load per connection
2. Flange thickness (both beams)
3. Flange width (both beams)
4. Flange type (or give angle of taper if not parallel)
5. Angle of crossover
