  • the transverse arm has at its end facing away from the first post a separate, second connecting head which is fixedly welded to the round tube.
  • the second connecting head similarly has a plug-on slot by which it is plugged onto an apertured disc of a second post and fixedly wedge-connected thereat by means of a wedge to be detachable again.
  • the apertured disc of the second post is secured to the second scaffolding post below the longitudinal centre thereof.
  • the second connecting head is connected by way of a separate, second post of the same length, but with an apertured disc mounted at a different height, to form a lateral frame stiff in bending and torsion.
  • Two railing securing devices in the form of bolts which are of the same form and extend perpendicularly to the longitudinal axis of the scaffolding post away therefrom, are secured to the second post above the apertured disc thereof.
  • the second post is built onto a short post with formation of a lateral vertical frame for connection of leading railing.
  • a scaffolding which is erected so as to form a facade frame with a leading railing, can be built up on this vertical frame element. It is not possible, without additional components, to suspend railing devices by railing securing devices of the second post to be secure against dropping down, particularly railing devices with at least one railing rod or constructed as a railing rod, the railing rod ends of which have a securing or suspension recess which is open towards side surfaces—which extend away from another—and downwardly.
  • the said separate, second post has the features a) to g) of claim 1 .
  • This scaffolding frame similarly includes an individual second scaffolding post.
  • a single apertured disc is similarly secured to this second scaffolding post below its longitudinal centre.
  • This second scaffolding post is provided with vertical bushes and with horizontal bushes, at each of which a hook-shaped end (not described in more detail) of a diagonal or lateral scaffolding element can be suspended.
  • a first horizontal bush is secured closely below the apertured disc and a second horizontal bush appears to be secured above the apertured disc at a spacing from the lower post end, which as measured from the figures corresponds with approximately 80% of the post length.
  • a first vertical bush appears to be secured in the region of the upper post end.
  • a second vertical bush appears to be secured at a height near to and below the longitudinal centre between the upper post end and the apertured disc.
  • a mentioned scaffolding element (not described in more detail) can indeed be suspended at each of the said bushes, but it is unclear how.
  • This second scaffolding post has the features a) to d) as well as h) to m) of claim 1 .
  • a further similar individual scaffolding post in the form of a scaffolding upright for system scaffoldings for equipping structures has become known from EP 2 083 132 A2.
  • This in turn carries an apertured disc closely below its longitudinal centre and has, above the apertured disc, two securing devices either in the form of tilt pins or in the form of upwardly open receiving brackets.
  • the tilt pins consist of a base, which is oriented at right angles to the tube of the scaffolding post, in the form of a bolt with a cylindrical cross-section.
  • a vertical slot is provided at its end remote from the tube. The cylinder sections adjoining the slot are each penetrated by a bore in which a bolt is arranged.
  • a tilt element is rotatably disposed on the bolt and is arranged to be pointed at its end hanging down under gravitational force.
  • the upwardly open receiving brackets which can be alternatively provided, are each produced from a receiving pin which is welded to the tube at an acute angle. Each receiving bracket therefore has a wedge-shaped form on its side remote from the base.
  • a receiving opening which results from the spacing of the free end of the receiving pin from the tube, is formed on its side remote from the base. Adjacent to the receiving opening the receiving pin is bent over approximately at right angles to the tube of the scaffolding post.

  • a passage opening, which is provided at the free end of the strut forming the railing, of the strut forming the railing has to be inserted into the said receiving opening and then introduced onto the receiving slot.
  • a further, similar individual vertical support for construction of a facade scaffolding which can be broken down and a method for assembly or disassembly of the facade scaffolding which can be broken down have become known from WO 98/07934 A.
  • Two special securing means for railing elements for example railing rods, are secured to this vertical support at a mutual longitudinal spacing above a single rosette provided for a floor plate, which rosette has passages for suspension of the floor plates.
  • This vertical support has an effective total length of approximately 2 metres.
  • the special securing means for the railing rods are attachment members extending substantially perpendicularly to the vertical support, wherein two alternatives of attachment members are disclosed.
  • each attachment member has on its upper side and lower side, respectively, two projections which are offset relative to one another and extend away from one another.
  • Each railing rod has two identical railing rod ends extending away from one another in opposite directions.
  • Each railing rod end is constructed as a continuously encircling strap having a rectangular passage.
  • the passage is formed as a slot, which as considered in a direction parallel to the railing rod longitudinal axis has a length and, perpendicularly thereto, a width with a transverse dimension smaller than the length of the passage.
  • the transverse dimension of the passage is selected so that the railing rod can, with execution of alternating pivot motions, be introduced onto the respective attachment member.
  • each attachment member is formed by two part members arranged one above the other, wherein one part member has two projections extending in the direction of the other part member and the other part member has two recesses aligned with the projections.
  • this is introduced by its strap above the lower part member similarly with execution of alternating pivot motions.
  • the assembler For erecting a facade scaffolding the assembler initially stands on a floor plate of a first level. In that case, the assembler is safeguarded by at least one railing element, which is detachably coupled to securing means of vertical supports associated with the first level.
  • the assembler After plugging of a further vertical support onto the lower vertical support by way of a plug connection the assembler suspends a further railing element by the ends thereof at a securing position, which is provided for that purpose, of a securing element of the further vertical support plugged onto the lower vertical support.

  • This scaffolding post has the features a) to g) of claim 1 .
  • a building scaffolding with at least two H-shaped vertical frames has become known from EP 2 503 075 A1.
  • Each of the H-shaped vertical frames consist of supports formed from two tubes. The two tubes are connected together by a cross member, which is welded to the tubes.
  • the vertical frame comprises two securing devices, which serve for arrangement of bars serving as means for safeguarding against falling down. Two of these securing devices are secured to each tube above the cross member.
  • Each of these securing devices is formed as an upwardly open receiving bracket.
  • Each receiving bracket is produced by a pin which is bent over twice substantially at right angles.
  • a receiving opening is formed on the side, which is remote from the ground, between the pin and the tube. The pin is bent over approximately at right angles adjacent to the receiving opening, so that a substantially vertical section results.
  • This securing device also serves for arrangement of bars which form the railing and thus a safeguard against falling down.
  • the bars have, at the ends thereof, flat members in which respective passage holes are arranged.
  • the scaffolding erector standing on stairs—from the hatch which is provided in a cladding. This takes place through introducing the pin of the receiving bracket into the passage hole of the bar. Subsequently thereto the other end of the bar is secured to the vertical frame in the region of the opening hatch in the same manner.
  • a detachably locked transverse strut which when further erecting of the building scaffolding is carried out forms a barrier for the scaffolding erector.
  • the scaffolding erector shall as a result be encouraged to suspend the railing bar for the next scaffolding bay—from the already safeguarded position in front of the transverse struts forming the barrier—at the securing devices of the vertical supports of the vertical frame of the adjacent scaffolding bay.
  • Each vertical frame of this building scaffolding does indeed include two vertical supports, but none of these supports is an individual support. As considered in a form detached from the H-shaped vertical frame, one of the supports has the features a), b), in part d), e) to g), in part h), i), k), m) and o) of claim 1 .
  • a similar H-shaped vertical frame for tubular scaffoldings is already known from the specification DE 10 2008 005 813 A1.
  • a vertical frame having a securing device which, from a safeguarded position, enables leading assembly of railing bars safeguarding against falling down.
  • this vertical frame is not in a position of preventing the scaffolding erector from walking on the scaffolding floor of a scaffolding bay not yet provided with a safeguard against falling down.
  • the method used therein for leading assembly of safeguards against falling down does not satisfy the high level of safety requirements.
  • the method already described therein for leading assembly of safeguards against falling down is also correspondingly expensive and less practicable.
  • This vertical frame does indeed also include vertical supports, but again none of these supports is an individual support. As considered in the form detached from the H-shaped vertical frame, one of the supports has the features a), b), in part d), e), in part h), i), k), m) and o) of claim 1 .

  • a single apertured disc, which is provided with passages, is secured by welding to each support at the respective securing position.
  • the passages serve for firm wedge-connection of rod elements, which are provided with so-called connecting heads, to the vertical support. Longitudinal bars and transverse bars are usually used as rod elements.
  • the transverse arm has at each of its securing ends facing away from one another a respective connecting head with a plug-in slot, by way of which the respective connecting head is plugged onto the respective apertured disc and fixedly welded thereto as well as to the respective vertical support.

  • the railing rod with a part of a railing rod end of its railing rod ends plugged into the vertical receiving slot, is placed or suspended on a horizontal support surface of a support element of the mount and subsequently pivoted upwardly into a horizontal installed setting.
  • This scaffolding frame does indeed also include vertical supports, but again none of these supports is an individual support.
  • this scaffolding frame with its special railing securing devices has a number of advantages by comparison with other railing securing devices of other scaffolding frames or also individual scaffolding posts.
  • a connecting arrangement consisting of this scaffolding frame and a railing device, which is detachably mounted on the special railing securing device thereof, can be produced particularly simply and economically, can be built up and taken down particularly simply and rapidly, offers particularly advantageous possibilities for installation and deinstallation of the railing device not only from the same scaffolding position, but also from below as a leading railing, and enables demounting of the railing device without requiring demounting of an adjacent railing device.
  • one of the two supports has the features a) to c) and e) to v) of claim 1 .
  • Two railing securing devices are secured at a mutual longitudinal spacing to each of the two vertical supports above the apertured disc, wherein a first railing securing device of the railing securing devices is secured approximately in the longitudinal centre between the apertured disc and the upper support end of the associated vertical support and wherein the second railing securing device of the railing securing devices is secured in the region of the upper support end of this vertical support.

  • this is impossible, or is possible only with very substantial strain, for the scaffolding erector and is connected with corresponding risks to safety.
  • one of the two supports has the features a) to v).
  • Facade scaffoldings are built up from the afore-mentioned vertical frame and scaffolding frame.
  • Such facade scaffoldings are predominantly work and protective scaffoldings for safe working on facades or a protective scaffolding which prevents falling down of persons or material.

  • Transverse girders and transverse girder elements for a modular scaffolding have become known from U.S. Pat. No. 3,656,580 A, which discloses at at least one of the ends thereof a connecting body with a guide pin, which widens in wedge shape in downward direction, and with a securing wedge placeable against the rear rest surface thereof, by means of which the respective transverse girder or the respective transverse girder element can be firmly clamped to one of several mounts of a scaffolding post to be detachable.
