Definitions
- the invention relates to a scaffold, in particular a mobile scaffold, having the features of the preamble of claim 1.
- a mobile scaffold and a method for assembling and disassembling this mobile scaffold are known.
- Such a mobile scaffold can also be referred to as a mobile work platform.
- a side guard rail consisting of a single scaffolding strut is mounted in advance, or two such side guard rails are each mounted in advance at a horizontal distance from each other, on horizontal rungs
- each 25 individual support struts extend in a straight line along their longitudinal support strut axis and have support strut ends extending away from each other in opposite directions, each of which is designed as a locking claw.
- Such locking claws are known, for example, from DE 37 02 152 A1 and the parallel EP 0276 489 as well as from DE 3822 215 A1 and the parallel EP 0 348 885 A2. They enable a positive and secure fixing of the components having these locking claws, such as scaffolding floors, diagonal struts and/or horizontal struts, to other scaffolding struts having a round cross-section, whereby they can be pivoted relative to these other scaffolding struts in the fixed state.
- first level preferably a first scaffold floor
- a lower level which is made up of a vertically positioned first support frame and a second support frame positioned vertically at a horizontal distance from it and a first scaffold floor.
- Each support frame is a ladder consisting of two support struts and several horizontal rungs that extend parallel between the two support struts and at equal distances from each other and are each rigidly connected to the two support struts.
- a third support frame designed as a third ladder with several horizontal rungs is first suspended either on the two first scaffold struts or on the additional component in a vertical intermediate assembly position with the aid of two first scaffold struts, which can later be or are installed as diagonals for diagonal bracing of the mobile scaffold, or with the aid of an additional component having one or more support frame suspension hooks, which function or function as a support frame suspension device during assembly of the mobile scaffold, whereby the two first scaffold struts or the additional component are or are supported on the already erected, lower, first support frame, which is designed as a first ladder with several horizontal rungs.
- two individual, straight-line extending, second scaffolding struts which also have a suspension unit in the form of a locking claw at their ends extending away from each other in opposite directions, are mounted as follows: First, a first, second scaffolding strut of the two individual, second scaffolding struts is attached to the top rung of an upper, fourth support frame with the first locking claw of its two locking claws. detachably suspended, which is designed as a fourth ladder with several horizontal rungs and which has already been placed on the lower, second support frame designed as a third ladder with several horizontal rungs.
- the first, second scaffolding strut is then suspended with the second locking claw of its two locking claws on an uppermost rung of the third support frame which is in its intermediate assembly position, for which purpose the third support frame was previously transferred from its vertical intermediate assembly position, still vertically supported either on the two first scaffolding struts or on the additional component, by pivoting relative to the first support frame about a horizontal pivot axis into an inclined intermediate assembly position.
- the second, second scaffolding strut of the two individual, second scaffolding struts is detachably suspended again with the first locking claw of its two locking claws on the uppermost rung of the upper, fourth support frame.
- the second scaffolding strut of the two second scaffolding struts is hooked into the top rung of the third support frame, which is in its slanted intermediate assembly position, with the second locking claw of its two locking claws.
- the third support frame which is in its slanted intermediate assembly position, is then guided upwards together with the two individual second scaffolding struts attached to it so that they can pivot relative to it, and placed on the already assembled, lower, first support frame. This brings the two individual second scaffolding struts into a horizontal position of use, in which they each form a simple, advanced side guard rail for a second level that immediately adjoins the first level.
- the two simple side guard rails are then mounted approximately three meters above a first standing height or above the first scaffolding floor.
- the first two scaffold struts which were used for intermediate support of the third support frame, are mounted as diagonal braces or, in case of using the separate additional component, two scaffold struts are mounted as diagonal braces.
- a second scaffold deck is mounted on the third support frame and on the fourth support frame in a Height approximately two meters above the first standing height or above the first scaffolding floor, respectively, is suspended from a rung of the third and fourth support frames.
- Each side guard rail of the two simple side guard rails mounted in advance is then approximately one meter above a second standing height or above the second scaffolding floor.
- side protection double railings In order to enable a simpler and quicker installation of a side protection railing that has greater stability, so-called side protection double railings have become known. These have both an upper strut for Installation at hip height as a handrail, as well as at least one lower strut for installation as knee protection or knee rail.
- Such side protection double railings are known, for example, from DE 79 25492 U, DE 297 14 266 U, FR 2 887 574 A1, FR 2 887 907 A1, FR 2 908 804 A1, DE 10 2009 041 437 and the parallel EP 2 299 028 A2 as well as DE 10 2009 041 448 A1.
- the side protection double railings disclosed therein also all have the disadvantage that they can be subsequently removed from the floor delimited and protected by them, even by unauthorized persons, which can also create a considerable safety risk with a danger to life and limb.
- Each upper chord suspension unit has a claw with a suspension opening.

- the claws of the lower chord locking claws of the lower chord each have a hanging opening.
- lattice girders could, provided they are dimensioned accordingly, possibly be hooked into two rungs of a ladder that are provided on the respective ladder at a suitable vertical distance from one another.
- lattice girders could then not be mounted in advance as a side protection double railing without a safety risk and, above all, such lattice girders could easily be dismantled from the floor that is intended to be delimited and protected by them, even by unauthorized persons. This would represent a considerable safety risk.
