Definitions

  • the invention relates to a work platform for fastening to a wall or formwork with a platform and a guardrail that can be pivoted onto the platform.
  • stage supports project upwards from the platform. They are attached to a wall or formwork at their upper end and lie on the wall or along their entire length Formwork on.
  • the stage supports are pivotable about an axis that is perpendicular to the plane containing the two stage supports and parallel to the stage level, so that they can be pivoted into a position parallel to the platform of the work platform in which they are need only a small transport height.
  • the invention has for its object to simplify the handling of the work platform during assembly and disassembly.
  • this object is achieved in that inclined supports provided for supporting the working platform are movable into a position in contact with the platform, and in that the protective railing and the inclined supports are movably connected to one another via an active connection which transmits the movement.
  • the advantage of the invention is that when the work platform is set up by pivoting the guardrail from a position on the platform of the work platform to an upright position, the inclined supports are also moved from the position in contact with the platform of the work platform to an inclined support position.
  • the invention can be implemented by articulated or cable pulls, or also by gear drives.
  • the protective railing of the work platform has railing supports which extend below the pivot axis of the protective railing, the lower end of each railing support being connected in an articulated manner to an inclined support.
  • the lower end of the guardrail supports of the guardrail is U-shaped, one leg of the U forming the guardrail support, the other leg of the U, which is considerably shorter than the aforementioned leg, with its free end the platform is pivotally attached and the yoke of the U is pivotally connected to an inclined support.
  • the U-shaped design of the lower end of the railing supports has the advantage that the pivot axis of the protective railing can be provided on the underside of the platform. Nevertheless, the guardrail can be swiveled flat onto the platform for transport.
  • links are provided for the movable connection of the inclined supports to the working platform, one end of which is pivotally connected to the platform and the other end is pivotably connected to an inclined support.
  • This handlebar can be provided under the work platform to take up support forces, or above the work platform to take up tensile forces if the inclined supports are provided as tension members above the platform of the work platform and serve to hang up the work platform. In both cases, a handlebar pulls an inclined support against the platform when the guardrail is pivoted onto the platform.
  • the embodiment of the work platform described above can be designed such that the platform, a railing support, an inclined support and a link form the four links of a flat kinematic chain with four joints.
  • Such The active connection optimally transmits the movement between the guardrail and inclined supports. Due to the pivotable connection of the guardrail with the inclined supports and their movable connection via the handlebars to the platform of the work platform, the inclined supports move into their intended position when the protective railing is pivoted.
  • At least one locking device is provided which prevents movement of the guardrail and the inclined supports, both in the assembled and in the dismantled state of the work platform.
  • This locking device can be captively connected to the work platform. It can be provided in such a way that it always remains in the same place on the work platform and does not have to be moved from one place to another place when the work platform is being assembled or disassembled.
  • the locking device has a U-shaped locking bracket. This allows a simple and user-friendly structure of this lock.
  • the guardrail of a preferred embodiment of the work platform has a hitch.
  • the hitch is conveniently provided on two railing supports in about half to two thirds of the height of the guardrail.
  • the working platform can be attached to this towing device both when it is set up and when it is removed.
  • the working platform when unlocked, can be unfolded by lifting it on the suspension device and thus set up.
  • the inclined supports are provided as tension members above the platform of the work platform, they can be designed for hanging on the upper edge of a formwork.
  • the platform of the work platform then hangs on the inclined supports and on the links that connect the inclined supports designed as tension members to the platform of the work platform.
  • the platform is located below the upper edge of the formwork, which allows workers standing on the work platform to work upright.
  • the work platform 1 shown in Fig. 1 consists of a platform 2, a guardrail 3 and inclined supports 4.
  • Die Platform 2 usually has two beams 5 each made of two angle profile bars (see FIG. 3) onto which wooden planks 6 are screwed transversely thereto, which form the accessible work surface of the work platform 1.
  • fastening means 7 are provided for fastening the working platform 1 to a wall or formwork. This page is called the fastening page below.
  • the protective railing 3 has two railing supports 9, to which two tubes 10 and a square tube 11 are welded in the transverse direction.
  • the two tubes 10 are located at the upper end and approximately halfway up, but the square tube 11 near the lower end of the railing supports 9 is still above the platform 2.
  • the lower end of the railing supports 9 is U-shaped with a long and a short leg 12 and a yoke 13.
  • the long leg of the U forms the actual railing support 9.
  • the yoke 13 of the U runs parallel to the beams 5 below the platform 2.
  • the short leg 12 of the U is pivotable about an axis 14 and fastened to one of the supports 5 at a distance from its end on the railing side, which corresponds approximately to the length of the yoke 13.
  • the yoke 13 and the short leg 12 are approximately the same length in the embodiment shown and are substantially shorter than the long leg of the U forming the railing support 9.
  • a U-shaped locking bracket 16 is held captive.
  • One leg 17 of the locking bracket 16 is held in the bore 15 by a compression spring 18 (see FIG. 3).
  • the other leg 19 of the locking bracket 16 is inserted with the guardrail 3 pivoted into a hole 20 in the rail-side end of the support 5 and passes through a hole 21 which is provided at a distance from the lower end of the railing support 9 so that the two holes 20, 21 cover 3 with the guardrail swung open.
  • the locking bracket 16 in FIG. 3 is pulled to the left in the direction of the arrow 22 until the leg 19 emerges from the bores 20, 21.
  • the guardrail 3 is then rotated about the axis 14 by 90 ° and folded onto the platform 2 of the work platform 1.
  • the leg 19 of the locking bracket 16 is inserted into the bores 23 now covered in the yoke 13 of the U of the railing support 9 and the bore 21 in the support 5, so that the protective railing 3 is locked in this transport position.
  • the distance between the bore 15 and the bore 21 corresponds to the distance between the bore 15 and the bore 23.
  • each railing support 9 is extended beyond the base point of the short leg 12 in the direction of the attachment side of the platform 2 of the work platform 1.
  • an inclined support 4 is pivotally attached to each of the railing supports 9.
  • a link 24 extends from each support 5 of the platform 2 to each inclined support 4.
  • the upper end of each link 24 is articulated on respective carrier 5 firmly near its attachment-side end.
  • the lower end of each link 24 is pivotally connected to the respective inclined support 4 approximately in the middle.
  • a trailer ring (not shown) is attached to each of the two railing supports 9 at approximately half to two thirds of the height of the protective railing 3.
  • the inclined supports 4 Due to the dimensions of the inclined supports 4 and the handlebars 24 and the arrangement of the pivot axes at the upper and lower ends of the handlebars 24 and the pivotable attachment of the inclined supports 4 to the railing supports 9, the inclined supports 4 are forced to move with the protective railing 3.
  • the leg 19 of the locking bracket 16 is pulled out of the bore 21, 23 against the action of the spring 18 and by attaching and lifting the work platform 1 on the guardrail 3 to a crane cable the guardrail 3 and thus at the same time the inclined supports 4 are pivoted into the working position in which they are locked in holes 20, 21 by inserting the leg 19 of the locking bracket 16.
  • the work platform 1 is now ready for use.
  • the railing support 25 shown in FIG. 4 differs from the aforementioned railing support 9 in that its pivot axis 26 is arranged in a projection 28 which projects beyond wooden planks 27.
  • the lower end of the railing support 25 has a leg 29 bent approximately at right angles below the work platform. The length of this leg 29 is equal to or greater than the thickness of the work platform, so that the pivot axis 26 arranged at its end for an inclined support 30 is also below the work platform when the railing support 25 about its pivot axis 26 in the transport position on the platform of the work platform worked. It is understood that in this embodiment, one of the corresponding locking devices shown in FIGS. 1 to 3 and described in the text must also be provided.
