A stud bridge member used in the construction industry to span horizontally between studs is disclosed. The stud bridge member has at least one set of notches that engage with the stud and eliminate the use of a stud bridge clip and its associated costs and installation time for that stud.

It is described herein a bridge clip comprising a web, a first flange, and a second flange. The web having a web first edge substantially parallel to a web axis, and a web second edge substantially parallel to the web axis. The first flange extends from the web first edge while the second flange extends from the web second edge. Each of the flanges comprises a tab having a vertical tab having a vertical tab face in a vertical tab plane substantially perpendicular to the web axis and oriented in a vertical tab face direction substantially parallel to the web axis. The first vertical tab face direction opposes the second vertical tab face direction. It is also described that there is a positive distance value between the first vertical tab face and the second vertical tab face.

A joint device includes a main fixing plate, an auxiliary fixing plate, and a fastener. The main fixing plate has a vertical wall disposed between a longitudinal beam and a transverse beam, a first extending wall extending towards a side of the longitudinal beam from the vertical wall and crossing over and abutting against an upper portion of the longitudinal beam, and a second extending wall extending towards a side of the transverse beam from the vertical wall and crossing over and abutting against a lower portion of the transverse beam. The auxiliary fixing plate is disposed in an open groove of the transverse beam in a way that the transverse beam is clamped between the auxiliary fixing plate and the vertical wall of the main fixing plate. The fastener secures the longitudinal beam, the transverse beam, the main fixing plate and the auxiliary fixing plate together.

The present invention relates to an elevator handrail supporting device including: a fixing plate assembly 20 and a bracket 50 coupled to the fixing plate assembly, in which the bracket includes T-nut guides 60, a T-nut 70 coupled to the T-nut guides, a stopper 80 being in contact with a bolt head, a bolt support 90, and a catching projection 96, and when the bracket 50 is fitted with the fixing plate assembly 20 coupled to a handrail 10, a stepped portion 94 of the catching projection 96 is engaged with and coupled to a catching hole 24, a bolt is fitted into a fastening hole 22, and then the bolt is tightened into a threaded hole 76 of the T-nut 70, the fixing plate assembly 20 is bent downward by elasticity so as to apply an upward force to the handrail 10.

A quick attachment system is disclosed. A first connector portion is defined along a surface of the first member and a second connector portion is defined along a surface of the second member. The first connector portion comprises a protrusion of the surface of the first member. The second connector portion comprises a detent of the surface of the second member. The first and second connector portions may mate with and engage one another to secure the first member against the second member. A modular frame unit comprises first and second channel members defining first connector portions along lengths thereof and a joinder channel member defining second connector portions along a length thereof. Each of the second connector portions is configured to mate with one of the first connector portions to join the joinder channel member with the first and second channel members.

A scaffold transom, particularly for the horizontally oriented installation in a scaffold section, the scaffold transom comprising at least one transom support which is rod-shaped and extends in the direction of a longitudinal axis, the transom support having two opposing ends in the direction of the longitudinal axis, and a connection interface being located at each of these two ends, which connection interface is provided for the connection to a scaffold element, at least two brackets which each extend along a bracket axis, the brackets each having two opposing ends in the direction of their bracket axis, one of said ends of each bracket being connected to the transom support, and at least two closures respectively one of which is located at the end of a bracket opposite of the connection of said bracket to the transom support.

A joint device includes a main fixing plate, an auxiliary fixing plate, and a fastener. The main fixing plate has a vertical wall disposed between a longitudinal beam and a transverse beam, a first extending wall extending towards a side of the longitudinal beam from the vertical wall and crossing over and abutting against an upper portion of the longitudinal beam, and a second extending wall extending towards a side of the transverse beam from the vertical wall and crossing over and abutting against a lower portion of the transverse beam. The auxiliary fixing plate is disposed in an open groove of the transverse beam in a way that the transverse beam is clamped between the auxiliary fixing plate and the vertical wall of the main fixing plate. The fastener secures the longitudinal beam, the transverse beam, the main fixing plate and the auxiliary fixing plate together.
