Definitions

  • the invention relates to a railing beam for a scaffold and to a scaffold with a railing beam according to the invention. Furthermore, the invention relates to a method for erecting a scaffold and the use of a railing beam according to the invention in a scaffold.
  • scaffolding can refer in particular to a modular or frame scaffolding.
  • Modular and frame scaffolding include prefabricated, standardized scaffolding components that allow the scaffolding to be set up and dismantled quickly, for example to scaffold a building facade.
  • Frame scaffolding has prefabricated vertical and horizontal frames.
  • Modular scaffolding includes individual vertical posts and horizontal bars that can be assembled into complex surface or room scaffolding using standardized connecting elements and/or connection nodes. Since scaffolding usually includes several scaffolding levels, fall protection in the form of railings is provided. If the scaffolding is still being erected, there is no fall protection until the railing is assembled.
  • a method for assembling and disassembling a demountable facade scaffolding in which the railing is designed as a leading railing is given as an example in the published patent application DE 196 33 092 A1
  • a railing element that belongs to a scaffold level to be erected before the floor plates of the scaffold level to be erected, it is coupled at one end to a support element that has already been installed in the area of the scaffold level to be erected and at the other end to another support element that has not yet been installed.
  • the railing element is then pivoted into a horizontal position and thus brought into its final position.
  • a method for attaching several railing elements to one level of a scaffold in which the railing elements have engagement means at their ends for engagement in a perforated rosette connected to a vertical support.
  • These engagement means are designed like hooks or claws, so that they enable the railing elements to be pivoted relative to the vertical support having the perforated rosette on one side when they engage with a perforated rosette.
  • the perforated rosette defines the fastening position of the railing elements.
  • the aim of the present invention is to simplify the assembly and disassembly of a railing beam when assembling or dismantling a scaffold.
  • suitable coupling means should ensure that the railing beam cannot be dismantled easily in the installed position, i.e. in its final position of use, but only gradually when the scaffold is dismantled.
  • the railing beam with the features of claim 1 and the scaffolding with the features of claim 7 as well as the method for erecting a scaffolding with the features of claim 11 are proposed.
  • a preferred use of a railing according to the invention in a scaffold is proposed.
  • a railing beam for a scaffold which has a coupling section at at least one end for coupling to a coupling element of a vertical post or vertical frame of the scaffold.
  • the coupling section is flat and is penetrated by an elongated opening running parallel to a longitudinal axis of the railing beam, which has a constant width up to an end extension.
  • the railing can be connected to a coupling element of a vertical post or vertical frame by hooking it into the extended opening at the end in the coupling section.
  • the extension at the end makes it easier to hook or thread the coupling element into the opening of the coupling section.
  • a positive connection can be achieved between the coupling section of the railing beam and a coupling element of a vertical post or vertical frame.
  • the coupling element of the vertical post or vertical frame has a bead-like projection, for example a mushroom-head-like design.
  • the coupling element forms an undercut area that can be gripped behind by the coupling section of the railing beam.
  • the coupling section is then hooked in via the end extension of the opening, which is preferably led to a side edge of the coupling section or has dimensions that are adapted to the dimensions of the bead-like projection.
  • the coupling section thus gets behind the bead-like projection of the coupling element when hooked in.
  • the positive connection is then achieved by moving the coupling section relative to the coupling element so that the coupling section grips behind the bead-like projection.
  • the width of the opening is preferably adapted to the width or diameter of the coupling element beyond the bead-like projection.
  • the positive connection between the coupling section of the railing beam and the coupling element of the vertical post or vertical frame prevents the railing beam from being unhooked in its final or use position. To remove it, the railing must first be moved again, which is not possible as long as the railing is coupled to two mounted vertical posts or vertical frames.
  • the opening of the coupling section is elongated makes it possible to move the railing beam relative to a coupling element of a vertical post or vertical frame. Since the opening extends parallel to the longitudinal axis of the railing beam, the railing beam is moved in the longitudinal direction.
  • the railing beam can be aligned horizontally or diagonally.
  • twisting and/or pivoting may also be necessary in order to bring the railing beam into its final or use position.
  • the elongated opening and/or the end extension of the opening is preferably arranged centrally in relation to the longitudinal axis of the railing beam.
  • the longitudinal axis of the railing beam therefore simultaneously forms the longitudinal axis of the opening and/or the extension. On the one hand, this makes it easier to manufacture the railing beam. On the other hand, no axis offset needs to be taken into account when erecting the scaffold.
  • the suggested railing beam is mounted at the height specified for fall protection.
  • the suggested railing beam can also be used to create knee beams. To do this, the railing beam only needs to be mounted at knee beam height.
  • the end extension is arranged at the end of the opening that faces away from the railing.
  • the end facing away from the railing is the outer end of the opening.
  • the opening therefore has a width that is smaller than the width of the extension.
  • the opening be widened on both sides.
  • the extension can in particular be arranged symmetrically to the opening.
  • the opening and the extension are preferably mirror-symmetrical in relation to the longitudinal axis of the railing beam.
  • the extension is arranged symmetrically, it cannot be guided to a side edge of the coupling section.
  • the coupling section cannot therefore be hooked directly behind a bead-like projection of a coupling element, but must first be guided over the bead-like projection.
  • the size and shape of the end extension is therefore preferably adapted to the size and shape of the bead-like projection.
  • the coupling element of the vertical post or vertical frame has a circular cross-sectional shape, as this enables the railing bar to be pivoted easily around the coupling element.
  • the end extension of the opening is rounded, in particular circular or partially circular.
  • the rounded shape of the end extension also helps ensure that the railing can be easily pivoted around the coupling element.
  • the outer end of the opening is rounded, in particular circular or partially circular. This always ensures that the railing can be easily pivoted. This is particularly advantageous when designing a leading railing, as the railing is pivoted to bring it into its position of use.
  • the railing beam must not only be pivoted during assembly, but may also be rotated. This is particularly the case if the end extension of the opening is not guided to a side edge of the coupling section.
  • the coupling element is also L-shaped, the coupling section must first be aligned horizontally or at least approximately horizontally in order to thread the coupling element into the opening. The railing beam must then be rotated about its longitudinal axis or an axis running parallel to it so that the coupling section is transferred from the horizontal position to a vertical position. The space in the area of the coupling element can be so cramped that there is little room to rotate the railing beam.
  • the coupling section therefore preferably has a reduced width at its end facing away from the railing beam or on the outside.
  • the coupling section preferably has a recess on both sides, so that the coupling section is mirror-symmetrical with respect to the longitudinal axis of the railing beam.
  • the coupling section has a circular arc-shaped front edge connecting the side edges of the coupling section in plan view.
  • the coupling section can, for example, be designed as a tab with a rounded end.
  • the rounding makes it easier to pivot the railing around the coupling element after it has been hooked in. This applies in particular if the circular arc-shaped front edge of the coupling section is arranged concentrically to a rounding at the outer end of the opening, so that the coupling section has the same width all around in the area of the opening. This ensures that the coupling section does not hit anything when pivoting.
  • the rounding at the outer end of the opening can be either a rounded end or a rounded extension of the opening at the end.
  • the railing is preferably made of a metal tube, as this has a high degree of rigidity and thus stability. At the same time, weight can be saved, as tubes are hollow.
  • the metal tube also preferably has a circular cross-sectional shape. There is therefore no risk of injury from the railing.
  • the railing is plastically deformed at at least one end to form or accommodate a coupling section. The plastically deformed end section creates the transition from the flat coupling section to the metal tube.
  • the railing requires less freedom of movement when pivoting.
  • coupling section and railing can be manufactured in one operation or separately and then joined together.
  • the proposed railing beam preferably has a coupling section at each of its two ends.
  • the railing beam can be arranged between two vertical posts of a modular scaffold or two vertical frames of a frame scaffold and attached to them.
  • the two coupling sections can be designed the same or differently. Specific embodiments are described in more detail below.
  • a scaffold in particular a module or frame scaffold, with at least one railing beam according to the invention and at least one vertical post or vertical frame
  • the vertical post or vertical frame has at least one coupling element for coupling with a coupling section of the railing beam.
  • the railing beam according to the invention simplifies the construction of the scaffold. It also enables the formation of a leading railing.
  • a positive connection can be achieved between the coupling section of the railing beam and the coupling element of the vertical post or vertical frame, which prevents the railing beam from being dismantled in its position of use, i.e. when the scaffold is fully assembled. This increases the safety of the scaffold.
  • One railing according to the invention at the beginning and at the end of a scaffold level is sufficient to secure other standard railings in the same scaffold level. This means that standard railings can still be used.
  • the coupling element is essentially L-shaped and has a first section connected to the vertical post or the vertical frame and a second section arranged at an angle, in particular at a right angle, to this, which extends preferably vertically upwards in the position of use of the vertical post or vertical frame.
  • the second section therefore preferably runs parallel to the vertical post.
  • the coupling element Due to the L-shape, the coupling element forms a kind of hook. This is open at the top so that when the railing is in use, the coupling section cannot be unhooked without lifting it, i.e. without external force. This is particularly true for a coupling section with an opening whose end extension does not extend to a side edge. In this case, the coupling section must be lifted not only over the horizontal first section of the coupling element, but also over the vertical second section.
  • the first section and the second section of the coupling element each have a circular cross-sectional shape.
  • the diameter is preferably chosen to be slightly smaller than the width of the opening of the coupling section of the railing beam.
  • the second section has a bead-like projection.
  • the bead-like projection forms an undercut area that can be gripped behind by the coupling section of the railing.
  • the second section of the coupling element can be designed like a mushroom head, for example. Because the coupling section grips behind the bead-like projection when the railing is in use, it is impossible to unhook the railing. This is because the bead-like projection cannot be overcome without moving the railing. However, moving the railing is not possible when the railing is in use.
  • the bead-like projection extends only over a partial circumferential area of the second section of the coupling element. This makes it easier to thread the coupling element into the opening of the coupling section of the railing beam when the scaffold is being erected, specifically in the area of the end extension of the opening.
  • the bead-like projection is advantageously arranged at least on the side of the second section of the coupling element facing the vertical post or the vertical frame, so that the distance between the second section of the coupling element and the vertical post or the vertical frame is reduced by the projection.
  • the distance between the second section of the coupling element and the vertical post or the vertical frame can in this case be chosen to be so narrow that the coupling section does not fit through in a horizontal position without first moving the railing beam. This can make unintentional dismantling of the railing beam even more difficult.
  • the method enables the railing to be installed from a lower scaffold level or a leading railing to be created. This increases safety when erecting the scaffold. After the scaffold has been erected, safety is also increased because the railing cannot be dismantled. Dismantling requires the railing to be moved relative to the coupling elements of the vertical posts or frames. To do this, one of the two vertical posts or frames would first have to be dismantled. The railing can only be dismantled gradually as the scaffold is dismantled or dismantled.
  • step a) and/or step b) of the method i.e. when coupling a coupling section of the railing beam with a coupling element of a vertical post or frame, the coupling element of the vertical post or frame is preferably brought into engagement with the opening of the respective coupling section of the railing beam.
  • the opening of the coupling section and the coupling element different procedures are possible.
  • the coupling element of the vertical post or frame is preferably L-shaped and has a first section and a second section arranged at an angle to the first section. Furthermore, both sections preferably have a circular cross-sectional shape.
  • the railing bar is first rotated such that the coupling section is aligned essentially horizontally and the extension is arranged above the second section of the coupling element of the vertical post or frame.
  • the coupling element is then brought into engagement with the opening in the area of the extension.
  • the railing bar is then rotated about an axis running parallel to its longitudinal axis until the coupling section is aligned vertically.
  • the railing bar is then moved so that the coupling element reaches the end of the opening that is not expanded. This ensures that the railing bar can no longer be unhooked.
  • the railing bar can also be moved first and then rotated. The movements can also be carried out simultaneously.
  • the proposed railing beam is particularly suitable for forming a leading railing
  • the use of a railing beam according to the invention in a scaffold, in particular in a modular or frame scaffold, for forming a leading railing is also proposed.
  • the railing beam can be easily mounted from a lower scaffold level or transferred to its position of use with the help of a second vertical post or frame. After the second vertical post or frame has been mounted, the railing beam can no longer be dismantled. In this way, the highest safety requirements are met.
  • Figure 1 shows a first embodiment of a non-inventive railing 10 in connection with a vertical post 30 of a modular scaffold 100.
  • the vertical post 30 is located in the Figure 1 in its position of use. In this position it is vertically aligned.
  • the vertical post 30 On the outer circumference, the vertical post 30 has several coupling elements 40 which are arranged at different heights.
  • the coupling elements 40 are each L-shaped so that they form a kind of hook.
  • the railing beam 10 is suspended in the area of a coupling element 40. In this position, the railing beam 10 can be connected to another vertical post (not shown) and with its help brought into its position of use (see Figure 3 ).
  • the additional vertical post 30 is mounted at the same time. In this way, a leading railing can be formed.
  • the railing 10 shown is made of a metal tube 13 which is plastically deformed at both ends 11, 12 and has a coupling section 20.
  • the coupling sections 20 are each flat and have an opening 21.
  • An extension 22 is provided at one end of the opening 21.
  • the coupling element 40 can be brought into engagement with the opening 21 of the coupling section 20 via the extension 22.
  • the opening 21 of the coupling section 20 has a width b1 which is slightly larger than the diameter of the coupling element 40 outside a bead-like projection 43.
  • the bead-like projection 43 is consequently engaged behind by the coupling section 20 of the railing beam 10 when the railing beam 10 is rotated from a position of use in such a way that it has the Figure 2
  • the railing beam 10 cannot therefore be unhooked accidentally.
  • the railing beam 10 would first have to be moved in such a way that the coupling element 40 reaches the other end of the opening 21, which has the extension 22.
  • this is not possible in the position of use of the railing beam 10 (see Figure 3 ).
  • the extension 22 is guided as a slot up to a side edge 24 of the coupling section 20.
  • the extension 22 therefore opens the opening 21 towards the side edge 24.
  • the extension 22 is chamfered on both sides in the area of the side edge 24.
  • the opening 21 is arranged centrally in relation to the longitudinal axis A of the railing beam 10, so that webs of the same width, each with a width a1, are created on both sides.
  • the width a1 is slightly smaller than the distance between the coupling element 40 and the vertical post 30. This enables the railing beam 10 to be rotated about its longitudinal axis A or an axis running parallel to it if necessary, without the railing beam 10 being able to be unhooked.
  • each coupling element 40 of the vertical posts 30 are shown to be designed to accommodate several, in particular two, railing beams 10.
  • each coupling element 40 has a first section 41 and a second section 42, which is arranged at right angles to the first section 41.
  • the second section 42 extends vertically upwards. This means that the second section 42 runs parallel to the vertical post 30.
  • the second section 42 also forms the bead-like projection 43.
  • the railing beams 10 are each supported via the first section 41 of the coupling element 40, so that the coupling sections 20 of the railing beams 10 are aligned vertically. Two railing beams 10 can therefore be arranged next to one another.
  • the coupling sections 20 of the two railing beams 10 lie flat on top of one another.
  • the vertical posts 30 can have further coupling elements in the form of perforated discs 50.
  • Scaffolding elements such as decking bars, longitudinal bars and/or diagonal bars (not shown) are attached.
  • Decking bars are used to hold a scaffolding deck 61, which is shown for example in the Figure 3 is shown.
  • a railing beam 10 can also have two differently designed coupling sections 20.
  • the right coupling section 20 is analogous to the coupling sections 20 of the embodiment of the Figure 4
  • the left coupling section 20, on the other hand, has an opening 21 without an end extension 22. Variations of this design are certainly possible.
  • a preferred embodiment of a railing beam 10 according to the invention is the Figures 6 , 7 and 8
  • the Figures 6 and 7 each show a first railing beam 10, which is already connected to a coupling element 40 of a vertical post 30, as well as a further railing beam 10 during assembly.
  • the coupling sections 20 of the railing beams 10 each have an opening 21 with an end extension 22, which is not guided to a side edge 24 of the coupling section 20, but rather maintains a distance a2 from the two side edges 24.
  • the extension 22 has a width b2, which is in principle larger than the width b1 of the opening 21.
  • the width b2 of the extension 22 is adapted to the bead-like projection 43 of the coupling element 40, so that the coupling section 20 can be guided over the bead-like projection 43 when hooked in.
  • the coupling section 20 is essentially aligned horizontally (see Figure 6 ).
  • the coupling element 40 is then moved from the area of the extension 22 to the other end of the opening 21 so that the coupling section 20 engages behind the bead-like projection 43 of the coupling element 40. Before or during this, the coupling section 20 can be brought into the vertical position by rotating the railing beam 10. The coupling section 20 thus comes to lie next to the coupling section 20 of the already mounted railing beam 10.
  • the rotation of the railing 10 requires a certain amount of freedom of movement, which in the embodiment of the Figures 6 and 7 is created in that the coupling section 20 has a width B2 at the end, which is smaller than a width B1 in the The area of the connection to the metal tube 13 of the railing beam 10 is reduced.
  • the side edges 24 of the coupling section 20 each have a recess 23 for this purpose (see also Figure 8 ).
  • the coupling section 20 also has a circular-arc-shaped front edge 25 connecting the two side edges 24. Since the circular-arc-shaped course of the front edge 25 is designed concentrically to the circular-arc-shaped course of the extension 22, the distance a2 of the extension 22 to the side edge 24 does not change in the area of the front edge 25. This means that the same freedom of movement is always required when pivoting the railing beam 10. The necessary freedom of movement is also created by the fact that in the embodiment of the Figures 6 and 7 the extension 22 of the opening 21 is arranged on the outside. If it were arranged on the inside, it would collide with the already mounted railing spar 10, as shown in the example in the Fig. 7 shown.
