Lateral connection system by removable clamps for I or H profiles

Posted by University of VigoResponsive · Patents for licensing · Spain

Summary of the technology

The presented system allows detachable lateral connections, at right angles, type ‘cross beam to column flange’ of I and H standard profiles made of steel. The system uses standard mounting clamps without previous specific machining operations (as may be welding or drilling).

Description of the technology

Assembly methods by welding or bolts commonly used in metallic structures have the disadvantage of not being easily removables and reusables, without further machining or welding operations. These type of connections are tailor made for a specific node. The proposed system can reduce or eliminate, as far as possible, the generation of waste in case of reconfiguration of the structure, being completely removable and reusable.


This patent consists in a lateral connection system at 90º angles of metal profiles type I or H, using supports pieces with slotted holes that allow the attachment of various sizes of standard profiles. For assembling the connecting support pieces, mounting clamps with bolts, nuts and flat washers are used. The supports are attached to the profile flanges, first to column flange, and then to the beam one.

Main advantages of its use

  • The system allows to save time in the assembly process. The set has a system for adjusting the stiffness of the connection.
  • This detachable connection allow reconfiguration and reuse of parts in metal structures made of I or H profiles, which represents an economic and environmental advantage.
