Product Group 7As well as trapezes, the components ofProduct Group 7 include attachment elementsconnecting directly to the structure, such astrapezes.

The permissible loads correspond with theload table for statically determined compo-nents on page 0.5 of the TechnicalSpecification.

For weld-on clevis type 73 and weld-on eyeplate type 75, the minimum weld thicknessesmust be considered. These are designed insuch a way that the maximum weld stressesdo not exceed 75N/mm2 during normal operating conditions.

The stress analysis is based on a loadapplied conically at under 6° angulation.

The weld-on clevis type 73 is particularlysuited for attachment to hollow sections.

The beam clamp type 78 is designed forunwelded on site attachment. The beamwidth is to be specified when ordering.

Trapeze types 79 are suitable for use withclamp base type 49 and can be used asrigid hangers or in conjunction with variableand constant hangers.

For protection against corrosion, the com-ponents are coated with a weldable primer(30µm) or electrogalvanized and then yel-low chromatized (zinc thickness 15µm).The trapeze sections are coated to the LISEGAstandard.

Material certification can be supplied for allcomponents on request.

Standardized connecting parts

The attachment of pipesupports to the load bear-ing structure is producedby means of special com-ponents to be welded orclamped. The safety of theconnections depends ontheir adaptation to the prevailing situation andtheir particular suitabilityin each case.

BEAM ADAPTER TYPE 76

For alterations or extensions to pipe systems or structural steel in existing plants, clamp connec-tions are often preferred to wel-ding for the necessary attachmentto the existing structure of pipe supports or additional steel. The use of this method is obligatory when welding is ruled out for safety reasons.The long-lasting security of this type of connection depends essen-tially on the condition of the contactsurfaces and the preset forces applied. For a reliable connection, the specific design of the clamp elements used is decisive.

Offering the utmost reliability, LISEGA beamadapters type 76 serve as secure connectionsfor this purpose.

These newly developed components enablethe attachment of diverse components toexisting steel without welding or drilling,while installation is simple and time-saving.LISEGA beam adapters adjust automaticallyon tightening to the thickness of the compo-nent to be clamped. If the given torquevalues are observed, the lasting security ofthe connection is guaranteed. Existing corro-sion protection, e.g. hot-dip galvanizing orcolor coating, is not impaired.

The unique feature of the LISEGA beamadapters is represented by the specialcontact elements. They adjust automaticallydue to their shape to any position and anyexisting sectional flange angles.

The hardened contact elements have a roun-ded grooved profile which presses into thecontact surface on tightening. This providesa form-fit grip which offers mechanical secu-rity against shifting in any direction.

Cross connection:The safe connection of beam sections toeach other is simple effected with an inlayplate and eight LISEGA beam adapters. Theload capacity of a cross connection is givenin the table below.

Cross connection

Interconnection of sections can be made directly or bythe use of a support plate. The load capacity of across connection can be taken from the table on theleft.
