摘要： The invention relates to a scaffold cross-bar (20) of metal with a round-tube carrier profile (21) of steel, consisting of a round tube and having an outside diameter (28), and a U-shaped reinforcing profile (22) of steel sheet. The U-shaped reinforcing profile (22) has a base profile (49) and two parallel profile legs (50.1, 50.2) which extend away from the base profile (49) in the same direction at a transverse spacing (52) from one another. Each profile leg (50.1, 50.2) has at least one opening (60.1, 60.2) for fastening and/or securing scaffold components on the scaffold cross-bar (20). The transverse spacing (52) of the profile legs (50.1, 50.2) is smaller than 0.6 times the outside diameter (28) of the round-tube carrier profile (21).

摘要： The invention concerns a metal scaffold bar (20.1) with a steel beam profile (21.1) comprising two beam profile ends (32.1, 32.2) that extend away from one another and to which a metal fastening means (33.1) is welded for detachably fastening the scaffold bar (20.1) to other scaffold parts (41). A U-shaped reinforcement profile (22.1) made of sheet steel is welded to the beam profile (21.1) using the fastening ends of the side branches of the U-shaped profile. The height of the U-shaped reinforcement profile is greater than the height of the beam profile and the width of the U-shaped reinforcement profile is smaller than the width of the beam profile by more than double the thickness of the beam profile (21.1).

摘要： The assembly has a slot that is designed with a shoulder of an upper head part, where the shoulder is extended in direction on its slot base or in area of slot base or in a rear area of the slot below horizontal upper slot surface. The shoulder is arranged in a supporting position above a horizontal upper boundary surface of an outer projection part of a projection (44). The shoulder is provided in the supporting position, if a wedge (62) is located in a locking position. A connection head (61) is clamped with a vertical scaffolding element (41) by the wedge.

摘要： A coating unit (20), comprising a lift-off protection (25) that is fastened in a face end region (21) of the coating unit (20) and is formed by a securing pivot lever (26), which can be manually pivoted about a pivot axis (27), which in the usage position (22) of the coating unit (20) is vertical, from an open position, in which the coating unit (20) can be placed onto a horizontal carrier (30) or lifted off therefrom, into a closed or lift-off protection position (31), and vice versa, in which the coating unit (20) is secured against lift-off from the carrier (30) when it is placed on the carrier (30). At least in the closed or lift-off protection position (31’) thereof, the securing pivot lever (26) is secured by a spring-elastic detent element (35) against accidental pivoting about the pivot axis (27) in an engagement position (29) such that pivoting of the securing pivot lever (26) about the pivot axis (27) from the closed or lift-off protection position (31) into the open position is only possible by applying an increased pivoting force. The invention also relates to a method for securing a coating unit (20) against lift-off from a carrier (30) and to a method for releasing a coating unit (20) that is secured against lift-off.

摘要： The invention relates to a closed vertical frame (25.1, 25.2) intended for the construction of a frame stanchion (20.1), preferably a supporting frame (21.1), particularly of a supporting frame tower (22.1), said vertical frame comprising at least two vertical supports (30.1, 30.2; 30.3, 30.4), which are disposed at a horizontal distance from each other, and comprising at least two horizontal arms (35.1, 35.2; 35.3, 35.4), which are disposed at a vertical distance from each other and each extend between the at least two vertical supports (30.1, 30.2; 30.3, 30.4) transversely to said vertical supports (30.1, 30.2; 30.3, 30.4). A first horizontal arm (35.1, 35.3) of said horizontal arms is welded on both ends to one of the vertical supports (30.1, 30.2; 30.3, 30.4) each in the region of the upper ends thereof, and a second horizontal arm (35.2, 35.4) of said horizontal arms is welded on both ends likewise to said two vertical supports (30.1, 30.2; 30.3, 30.4) in the region of the lower ends thereof. The vertical frame (25.1, 25.2) is reinforced with at least one diagonal rod (40.1, 40.2), which extends between two of the vertical supports (30.1, 30.2; 30.3, 30.4) and two of the horizontal arms (35.1, 35.2; 35.3, 35.4) and is welded onto two of the vertical supports (30.1, 30.2; 30.3, 30.4). In the region of the respective upper end and/or in the region of the respective lower end of at least two of the vertical supports (30.1, 30.2; 30.3, 30.4), a perforated disk (45) provided with a plurality of openings is attached by welding in order to connect holding devices, for example scaffold bars and/or scaffold diagonals, particularly of a module scaffold. The perforated disks (45) are disposed concentrically to the respective vertical support and surround the vertical support in a flange-like manner. The first horizontal arm and/or the second horizontal arm comprise a connecting head (50), which is welded onto the vertical support (30.1, 30.2, 30.3, 30.4) and to the perfo

摘要： The invention relates to a supporting device (10) of metal for suspending a hanging scaffold (35) or another hanging structure. The supporting device (10) comprises a scaffold pole (11) having a welded-on sheet metal structure which forms a connection head (12) and which serves as a receptacle for a threaded bar part (53) of a threaded bar (13) having a height-adjustment nut (14) screwed thereon. The height of the scaffold pole (11) can be changed using the height-adjustment nut (14) even still with the hanging scaffold (35) suspended or with another hanging structure suspended, that is to say retroactively.
