摘要： A scaffold and method(s) for installing or removing such a scaffold that is constructed of at least two vertical frames and of at least two connecting elements that extend essentially horizontally, in each instance, includes at least one connecting element serving as a hip and/or back railing element, vertical supports having respective effective lengths essentially corresponding for example to the vertical distance of the attachment position for the hip and/or back railing element, and horizontal arms set onto one another to form transverse rungs, in each instance, of a ladder for allowing a person to climb up.

摘要： A scaffold cross-bar of metal with a round-tube carrier profile of steel includes a round tube and has an outside diameter, and a U-shaped reinforcing profile of steel sheet. The U-shaped reinforcing profile has a base profile and two parallel profile legs which extend away from the base profile in the same direction at a transverse spacing from one another. Each profile leg has at least one opening for fastening and/or securing scaffold components on the scaffold cross-bar. The transverse spacing of the profile legs is smaller than 0.6 times the outside diameter of the round-tube carrier profile.

摘要： A truss frame for a bridge and/or support includes two elongated, parallel longitudinally-extending post pipes having an outer circumference; two parallel crossbars extending perpendicularly to the post pipes; and a length-adjustable elongated diagonal element. The parts are hingedly and detachably bolted to one other. Two parallel connecting plates secured near each post pipe end extend away from one another on a common, imaginary plane containing the post pipe and crossbar longitudinal axes. Each crossbar and diagonal element has opposite ends hingedly and detachably bolted to a connecting plate. At least two rosettes are welded to each post pipe at a distance from one another corresponding to an integer multiple of a module scaffold modular size. A connecting body is welded to the connecting plate near at least two post pipe ends associated with the same crossbar and surrounds the respective post pipe outer circumference.

摘要： An overlap arrangement of at least two decking planks, for example for construction scaffolding, includes first and second decking planks composed of metal. Each decking plank has a decking surface composed of sheet metal, which is provided with essentially round passage holes, which are delimited, in each instance, by a beaded and circumferential hole edge. The first decking plank and the second decking plank are braced, relative to one another, without play, in releasable manner, using a locking screw composed of metal, to prevent displacement relative to one another in a displacement plane that runs parallel to their decking surfaces, and to prevent lift-off from one another, with force fit and shape fit, wherein the locking screw is screwed in, with its thread, without any plastic deformation and without plastic widening of the hole edge of a passage hole of at least one of the decking planks.
