Mechanical coupling arrangement for a lattice support beam

摘要

Disclosed herein is a mechanical coupling arrangement for a lattice support beam having a longitudinal direction and a transverse direction, said mechanical coupling arrangement comprising at least a first chord member, a first diagonal member, and a connector element for joining said first chord member with said first diagonal member, wherein each of said first chord member, said first diagonal member, and said connector element is made of extruded aluminum profile, said connector element comprising at least a first attachment portion having a first contact surface in contact with said first chord member, and a second attachment portion having a second contact surface in contact with an abutment surface of said first diagonal member.

1. A mechanical coupling arrangement for a lattice support beam, said mechanical coupling arrangement having a longitudinal direction and a transverse direction, and comprising:
at least a first chord member, a first diagonal member, and a connector element for joining said first chord member with said first diagonal member, wherein each of said first chord member, said first diagonal member, and said connector element is made of extruded aluminum profile; said connector element comprising at least a first attachment portion having a first contact surface in contact with said first chord member, and a second attachment portion having a second contact surface in contact with an abutment surface of said first diagonal member; said first contact surface comprising at least one rib-shaped projection running in said transverse direction and engaged in at least one corresponding groove-shaped recess arranged in said first chord member; said second contact surface is pressed against said abutment surface of said first diagonal member by means of at least one fastener penetrating through the second attachment portion, wherein the longitudinal direction of the at least one fastener is arranged substantially parallel with a longitudinal direction of said first diagonal member.
