Definitions

  • the invention relates to a corner strut for a modular scaffolding and a modular scaffolding with a corresponding corner strut. Furthermore, the use of the corner strut in a modular framework is suggested.
  • a modular scaffolding includes prefabricated, standardized scaffolding components that enable the scaffolding to be quickly assembled and dismantled, for example for scaffolding a building facade.
  • the scaffolding components are connected via standardized connecting elements and/or connection nodes that enable connections from different directions.
  • the scaffolding components can thus be assembled into complex surface or spatial scaffolding.
  • the modular scaffolding When scaffolding a façade, the modular scaffolding is usually attached to the façade via scaffold anchors from a certain scaffolding height.
  • the fastening is intended to prevent the scaffolding from tipping over.
  • the scaffolding height increases, so do the loads that act on the scaffolding components and their connections. Particularly in the connection area of a horizontal beam to a vertical support, overstressing can occur, so that there are limits to the height of the scaffolding.
  • the present invention attempts to remedy this.
  • the load-bearing capacity of a modular scaffolding in the connection area of a horizontal bar on a vertical support should be increased.
  • the additional scaffolding component should be as easy and quick to assemble as possible.
  • corner strut with the features of claim 1 and the modular framework with the features of claim 7 are proposed.
  • Advantageous developments of the invention can be found in the respective subclaims.
  • the use of the corner brace in a modular framework is suggested.
  • the proposed corner strut therefore has different connecting elements or connecting means at both ends.
  • This means that the corner brace is connected to the vertical support in a different way than the corner brace is connected to the horizontal beam. Since the connection of the corner strut to the horizontal bar is subjected to a significantly lower load than the connection of the corner strut to the vertical bar, the first connecting element, which serves to connect the corner strut to the horizontal bar, can be designed to be comparatively simple.
  • the first connecting element can be, for example, a bolt, a hook, a locking lug or a pawl, which can be brought into engagement with a recess in the horizontal bar and is formed by a base body of the corner strut or is arranged on the base body. By simply inserting, twisting, moving and/or pivoting, the connecting element can then be brought into engagement with the recess in the horizontal bar. This means that no tools are necessary to create the connection between the corner brace and the horizontal bar.
  • the first connecting element is designed as a bolt, it can be designed like a key, in particular have at least one geometry protruding on the outer circumference, which can be brought into engagement with a key recess of the same design in the horizontal bar.
  • assembly requires a specific alignment of the bolt and thus the corner brace in relation to the horizontal bar.
  • a positive fit can then be achieved, which secures the connection of the corner strut to the horizontal bar.
  • the recess for receiving the first connecting element of the corner strut is preferably arranged on the underside of the horizontal bar.
  • the corner brace is then attached to the horizontal bar from below during assembly. If the top side of the horizontal bar is designed to be the same as the bottom side, so that the installation position is arbitrary, the “top side” can also have a recess for receiving the first connecting element of the corner strut. Furthermore, the horizontal bar can have more than just one recess, so that corner struts of different sizes can be connected to the horizontal bar.
  • the corner strut After inserting the first connecting element into the recess of the horizontal bar, the corner strut can be connected to the vertical stem.
  • the corner brace then transfers loads from the horizontal beam into the vertical support, with the corner brace primarily being loaded in compression.
  • the corner brace helps ensure that the specified angle between the horizontal bar and the vertical support is maintained under load.
  • the connection area of the horizontal beam to the vertical support is therefore not only reinforced, but also stiffened.
  • the additional connecting means provided for connecting the corner strut to the vertical stem can be designed differently - depending on the respective requirements.
  • Embodiments are proposed below, which have in common that the connecting means for connecting to the vertical stem each have a connecting element that is movable relative to the corner strut and locking means for locking the movable connecting element.
  • the further connecting means comprise a first pipe clamp part as a movable connecting element and a second pipe clamp part fixed to the corner strut, to which the first pipe clamp part is connected via a joint. Due to the articulated connection of the two pipe clamp parts, they can be placed around the vertical support and then connected to form a pipe clamp that encompasses the vertical support.
  • the corner strut is connected to the vertical stem via a pipe clamp. This has the advantage that the corner strut can be connected to the vertical support at any point or over the entire length.
  • the pipe clamp enables relatively even load transfer to the vertical support.
  • the articulated connection of the two pipe clamp parts is designed in such a way that the first connecting element can be rotated or pivoted about an axis of rotation which runs parallel to the longitudinal axis of the vertical stem.
  • the locking means for locking the movable connecting element include a bolt, in particular a screw bolt, for clamping the further connecting means, in particular the two pipe clamp parts.
  • the bolt or screw bolt enables a detachable connection of the connecting means to the vertical support, so that the corner strut can be easily dismantled when dismantling the modular scaffolding.
  • the corner brace can therefore be used multiple times.
  • the bolt has a joint part at a first end, which is rotatably received in a bearing section of the second pipe clamp part, so that the bolt can be pivoted relative to the second pipe clamp part.
  • the pivotability of the bolt allows the pipe clamp to be opened and closed without having to loosen the bolt.
  • the joint part for the rotatable mounting of the bolt can, for example, be a pin which runs perpendicular to the longitudinal axis of the bolt and which has protruding ends on both sides, which are each rotatably accommodated in the bearing section of the second pipe clamp part.
  • the axis of rotation runs parallel to the longitudinal axis of the vertical support.
  • the bolt preferably has a thread for receiving a nut.
  • a force can be exerted by tightening the nut arranged on the thread, by means of which the two pipe clamp parts can be clamped together.
  • the corner strut is held securely on the vertical support via the pipe clamp.
  • the nut simply needs to be loosened enough so that the bolt can be pivoted to open the pipe clamp. This means that the nut can remain permanently on the thread of the bolt. As a result, it cannot be lost either. All parts that are required to connect the corner strut to the vertical support are therefore part of the corner strut, so that no further connecting and/or fastening means are required.
  • the first pipe clamp part has a receptacle into which the bolt can be inserted, in particular pivoted.
  • the bolt By inserting, in particular pivoting, the bolt into the receptacle, the first pipe clamp part can be guided behind the nut, so that the nut only needs to be tightened to clamp the two pipe clamp parts.
  • the receptacle is preferably designed to be open so that the bolt can be pivoted in. This means that the recording is not enclosed on all sides. Otherwise, in order to close the pipe clamp, the nut would first have to be unscrewed, the bolt passed through the holder and then the nut screwed back on. This is possible in principle, but has the disadvantage that the mother could be lost.
  • the further connecting means for connecting the corner strut to the vertical post comprise a pawl as a movable connecting element.
  • the pawl can be brought into engagement with a recess in the vertical handle, preferably via a free end designed as a hook or locking lug. No tools are required to make this connection, so it can be made quickly and easily.
  • the pawl In contrast to a pipe clamp, the pawl requires a recess in the vertical stem, so that the connection of the corner strut to the vertical stem via the pawl cannot be made at any point. However, if there is a corresponding recess in the vertical handle, insertion or
  • Engaging the pawl with the recess can be accomplished quickly and easily.
  • the pawl preferably has an eye for receiving a guide element, via which the pawl is guided in a slot-like recess in the corner strut.
  • the guide limits the mobility of the pawl, so that it cannot be easily pulled out of the recess when it is in engagement with the recess of the vertical handle.
  • the guide element is preferably designed as a ring which is held captively in the slot-like recess of the corner strut and in the eye of the pawl.
  • the ring can also be used in a simple manner to fix locking means, which are described below.
  • the second embodiment also has locking means for locking the movable connecting element.
  • the locking means preferably comprise a movable wedge element which is movably mounted in a slot-like recess in the corner strut via at least one pin.
  • the pawl can be brought into engagement with the recess of the vertical handle and fixed or locked in this position.
  • the wedge element thus increases the security of the connection of the corner strut to the vertical support.
  • the wedge element is preferably movably mounted in a further slot-like recess in the corner strut, so that the wedge element can be moved independently of the pawl.
  • the corner strut therefore preferably has several backdrop-like recesses.
  • the wedge element is arcuate or sickle-shaped and has an end that can be brought into engagement with the recess of the vertical handle.
  • the pawl can therefore be completely fixed, since the freedom of movement required to pull it out or swing it out is missing.
  • This is preferably completely filled by the wedge element.
  • the recess in the vertical stem is preferably designed as an elongated hole. This not only makes it easier to swing the pawl with the end hook in and out, but also creates additional space to accommodate the wedge element.
  • the wedge element has an eye for rotatably receiving a bracket, which can be brought into engagement with the guide element of the further connecting means.
  • the position of the wedge element can be secured with the help of the bracket that engages with the guide element.
  • the design of the guide element as a ring proves to be an advantage, since the bracket simply has to be inserted into the ring to secure the position of the wedge element.
  • the bracket is biased against the wedge element via a spring and a nut.
  • the bracket can thus be engaged against the spring force of the spring, for example in order to be brought into engagement with the guide element, which is designed as a ring, of the further connecting means.
  • the release movement of the bracket, which is then caused by the spring force, then leads to a pre-tensioning of the bracket against the ring, so that it is held securely in the ring.
  • All other connecting means and locking means of the second embodiment are held captively on the corner strut, so that there is no need to look for further connecting and/or fastening means when assembling the corner strut. This allows the corner brace to be installed particularly quickly. The corner brace can also be installed without the use of tools.
  • the corner strut according to the invention preferably has a base body which is made from a plate material or from a piece of pipe.
  • the base body can in particular be made from a plate material or be a simple plate. To increase the load capacity, the base body can alternatively be made from a piece of pipe.
  • the base body is preferably made from a piece of pipe, and more preferably from a square tube.
  • a piece of pipe in particular a square pipe, as a base body facilitates the formation of the at least one slot-like recess.
  • the pawl and/or the wedge element can be located on the inside, that is, within the pipe section or square tubes can be arranged so that they are held captively and protected from external influences.
  • a modular framework is also proposed that comprises at least one corner strut according to the invention.
  • the corner strut is connected at one end to a horizontal bar and at the other end to a vertical post of the modular framework.
  • the corner brace reinforces and stiffens the connection of the horizontal bar to the vertical post, so that high loads, for example due to large scaffolding heights, can be absorbed.
  • the corner strut can be arranged on the inside, i.e. on the facade side of the modular framework, or on the outside. It is preferably arranged below the horizontal bar, so that the horizontal bar rests on the corner strut and is additionally supported by the corner strut.
  • the horizontal bar preferably has at least one recess for receiving the first connecting element of the corner strut.
  • the at least one recess is preferably formed on the underside of the horizontal bar, so that the corner strut can be attached and mounted from below.
  • the position of the corner strut in relation to the horizontal bar is secured by the connecting element of the corner strut received in the recess. Because the horizontal bar not only rests on the corner strut, but the corner strut engages in the recess of the horizontal bar.
  • the connecting element of the corner strut inserted into the recess of the horizontal bar engages behind the wall of the horizontal bar.
  • At least one recess can be provided on several sides for receiving the connecting element of the corner strut.
  • the size and/or shape of the recess depends on the design of the connecting element.
  • the recess can be designed as a key recess into which a connecting element of the corner strut designed as a key-like bolt can be inserted.
  • the recess can be designed as an elongated hole, which enables insertion, in particular pivoting, of a connecting element designed as a locking lug or pawl.
  • the vertical stem has at least one recess for receiving a further connecting element Connecting means and/or a wedge element which has locking means.
  • the at least one recess is therefore provided in particular when the connecting means for connecting the corner strut to the vertical stem are designed analogously to the second embodiment described above.
  • the at least one recess in the vertical stem is preferably designed as an elongated hole running parallel to the longitudinal axis of the vertical stem.
  • the recess in the vertical handle allows the connecting element or the pawl to be pivoted in and creates additional space to accommodate the locking means or the wedge element. After inserting the pawl into the recess, the pawl can then be locked in the recess with the help of the wedge element.
  • corner brace according to the invention can be assembled quickly and easily. If the modular framework needs to be dismantled, it can be dismantled just as easily and quickly. Thanks to the reinforcement and bracing provided by the corner brace, the modular framework can accommodate higher loads. In particular, the scaffold height can be increased.
