Definitions

  • the present invention relates to the area of scaffolding systems, and in particular to the area of scaffolding systems comprising horizontal railing elements engaging with vertical carrier posts by means of locking elements inserted into overlapping openings in engagement parts of the vertical carrier post and the horizontal railing element, respectively.
  • Scaffolding systems in general are well known from a variety of application areas.
  • the area of construction is a major application area, both in respect of erection and maintenance of constructions, where the scaffolding is used as working platforms for construction workers.
  • Other areas of application may be temporary building structures, stages and similar structures.
  • a basic scaffolding system comprises two rows of vertical posts, which can be connected together for building a multi-storey scaffolding system, and substantially horizontally extending elongate bars, connecting the vertical posts juxtaposed to each other in a direction along and a direction orthogonal to a facade. Since the vertical posts and the horizontally extending elements are connected orthogonally to each other forming a substantially rectangular frame structure, diagonal supports can be added at regular intervals for securing the scaffolding system against collapsing. Deck or floor elements covering rectangles formed by the connections made in the substantially horizontal plane at regular intervals complete the scaffolding system.
  • a number of deck or floor elements can have openings with a hatch, which can be hinged, and a ladder extending from one deck through an opening in a subsequent deck makes it possible to ascent and descent between storeys.
  • a scaffolding system comprising vertical posts with annular apertured connecting elements spaced along the lengths of the posts and horizontally extending elongate scaffolding elements, which are locked to the annular apertured connecting elements by means of an engagement element, is known.
  • the engagement element has a connecting element-receiving slot by means of which the engagement element may engage with the apertured connecting element at both the bottom and top faces of the connecting elements.
  • a wedge is used as locking element between the engagement element and the apertured connecting element on the vertical posts.
  • the apertured connecting elements are connected to the vertical posts by means of welding, riveting, screws or other similar methods.
  • Such scaffolding systems are generally assembled by successively erecting individual scaffolding planes, with the individual member of the vertical posts of a first scaffolding plane ending as a rule in each case just above a floor plate belonging to a second scaffolding plane positioned above it.
  • This upper end of the vertical post is then coupled by the installer to the lower end of a further vertical post in an end to end continuation for a further scaffolding storey by means of a spigot connection.
  • This type of scaffolding system provides a high degree of safety when established.
  • An objective of the present invention is to maintain the level of safety during the erection of the scaffolding while increasing the safety level of the erected scaffolding structure for such structures erected under safety provisions.
  • the objective is in one aspect of the invention achieved through a scaffolding structure comprising a number of vertical support posts and between sets of two vertical posts, a horizontal railing element attached to the two vertical posts at the ends, where for the attachment of the railing element the vertical posts are provided with an connecting element comprising at least one opening extending essentially vertically and where for the attachment the railing element comprises an elongate bar and at one end of the elongate bar an engagement element for accommodating the connecting element and with openings adapted to be placed overlapping the opening of the connecting element on the vertical post and where further a locking element is provided for insertion through the openings of the connecting element of the vertical post and the engagement element of the railing element to prevent horizontal movement of the railing element, where the engagement element of the railing element is movable relative to the elongate bar between at least a first and a second position, where the locking element is mounted in the engagement element of the railing element to be movable from a mounting position to a locking position, and where the locking element is adapted to
  • the erecting of the structure may be performed from a lower deck of the structure, while achieving a desired safe construction with locking elements in the connection between the vertical posts and the horizontal railing elements.
  • the engagement element of the railing element is adapted to be movable along the longitudinal axis of the elongate element or bar.
  • the railing element comprises elongate apertures in the side walls adapted to accommodate a shaft element extending through the apertures and holding the engagement element, allowing the engagement element to travel along the elongate aperture.
  • the railing element comprises a fixed shaft element extending from the wall of the railing element and through an elongate aperture in the engagement element allowing the engagement element to travel along the shaft element.
  • the engagement element of the railing element comprises parts protruding to overlap the engagement element of the vertical post above and below this. Hereby both upward and downward movement is prevented.
  • the objective is in another aspect of the invention achieved through a railing element for a scaffolding system, where the railing element is characterized in that the engagement element of the railing element is movable relative to the elongate bar between at least a first and a second position, where the locking element is mounted in the engagement element of the railing element to be movable from a mounting position to a locking position, and where the locking element is adapted to maintain the mounting position, and upon movement of the engagement element relative to the elongate bar the locking element is adapted to be released to move into the locking position.
  • the engagement element of the railing element is adapted to be movable along the longitudinal axis of the railing element.
  • the railing element comprises elongate apertures in the side walls adapted to accommodate a shaft element extending through the apertures and holding the engagement element, allowing the engagement element to travel along the elongate aperture.
  • the railing element may comprise a fixed shaft element extending from the wall of the railing element and through an elongate aperture in the engagement element allowing the engagement element to travel along the shaft element.
  • the engagement element of the railing element comprises parts protruding to overlap the connecting element of the vertical post above and below this.
  • the locking element comprises an incision or a protrusion adapted to hold the locking element relative to the elongate element.
  • both ends of the elongate bar are provided with similar engagement elements, which will simplify both manufacturing and assembly of the scaffolding structure.
  • the objective is in a further aspect of the invention achieved through methods for erecting and dismantling the scaffolding system according to the invention.
  • a method for erecting a scaffolding structure comprises that the locking element in mounted in a mounting position, where the railing element is positioned to accommodate the connecting element of a vertical post between two protruding parts of the engagement element, and where the elongate bar is moved to cause the relative movement between the elongate bar and the engagement element and hence release the locking element from the mounting position and allowing this to propagate into the locking position.
  • a first method for dismantling a scaffolding structure comprises that the vertical post carrying one end portion of a railing element is dismantled and lowered to a lower position of the scaffolding structure and where the locking element is released from the locking position to allow the engagement element to be released from the connecting element, and where following this the vertical post carrying the opposed end of the railing element is dismantled and lowered to a lower position where the locking element of the opposed end of the railing element is released from its locking position allowing the railing element to be removed with both ends free.
  • a second method for dismantling a scaffolding structure comprises that the locking element is released from its locking position and where the engagement element is released from the connecting element, where the locking element is inserted into the locking position in relation to the engagement element and where the engagement element with the locking element protruding downwards is placed on top of the connecting element with the locking element protruding through the aperture in the connecting element, where following this the vertical post carrying the opposed end of the railing element is dismantled and lowered to a lower position where the locking element of the opposed end of the railing element is released from its locking position allowing the railing element to be removed with both ends free.
  • a third and preferred method for dismantling a scaffolding structure according to the invention comprises that the elongate bar is brought to engage with the locking element and by movement in an upward direction releases the locking element from the locking position with the engagement element and the connecting element to a position where the engagement element may be retracted from the connection element.
