Definitions

  • the invention relates to a railing, in particular a scaffold railing and a method for building a railing arrangement, in particular for securing work surfaces on a scaffolding, and a railing strut for releasably attaching the railing in a railing arrangement.
  • scaffolding is often used, which are constructed from a variety of interconnected scaffolding struts and scaffolding planks arranged therein to form work surfaces. Since some of the scaffolding reaches very high heights and sometimes difficult work is carried out on the scaffolding that requires a high concentration on this activity, the scaffolding, especially the work surfaces or stand areas, must be specially secured for the workers so that it does not carelessness leads to serious accidents. For this reason, scaffolding railings are usually provided on the scaffolding on the side facing away from the building, which are to prevent falling from a work surface. However, it often happens in construction that the scaffolding railings, which are absolutely necessary for safety, are removed for reasons of convenience, for B. to move bulky objects more easily. However, since the scaffolding railing is often forgotten afterwards, this creates considerable risk potential for workers who work on such scaffolding.
  • this railing should be safe and easy to handle and manufacture, and in particular should be robust for normal use on construction sites.
  • special coupling elements which are designed as latching elements, are used at the two ends of the railing struts, which are preferably designed as a hollow tube or rod, possibly as a hollow material.
  • the railing strut is attached to corresponding receiving elements of the scaffolding struts or scaffolding tubes standing vertically in the erected scaffolding, these receiving elements preferably being firmly connected to the scaffolding tubes, for example welded and preferably being formed from circular or essentially circular or rosette-like disks.
  • the hook-shaped latching element is formed at least at one end of the railing strut with a slit-shaped hook mouth or hook opening which extends obliquely inwards from the free end of the coupling element towards the mouth opening and is delimited on the outside by a hook nose which forms an undercut. in such a way that the hook nose engages behind the receiving element from below in the blocking position.
  • the railing strut is suspended at one end with the locking element with a slot-shaped hook mouth in a corresponding locking receptacle of the receiving element.
  • the railing strut is captive and thus securely received on the receiving element of the scaffold tube.
  • the scaffold tube to be connected is placed at a slight angle so that the hook can be hooked into the corresponding receiving element or its opening. If this scaffold tube is then placed vertically again, then the railing strut is also captively held in the receiving element and on the scaffold tube with this end. This allows the scaffold to be created in sections.
  • a catch element is formed at least at one end of the railing strut, in which the hook mouth widens outwards, the hook jaw expediently extending outwards from an obliquely directed and obliquely outwardly directed hook nose is limited.
  • This expediently has an outwardly protruding securing projection, which is expediently formed parallel to the longitudinal axis of the railing strut. This also ensures a self-locking hooking of the railing strut in the corresponding receiving elements of the scaffold tubes.
  • this widening hook jaw is coupled to another latching element according to the invention, ie the latching element with widening hook jaw is arranged at one end and a latching element according to the other embodiments of the invention is arranged at the other end, in particular one with a slot-shaped one hook mouth.
  • the coupling element arranged on the rod of the railing advantageously has a latching element which can engage in a latching receptacle in the receiving element which is arranged on the railing strut, so that an undercut in the secured position of the railing prevents the railing from detaching from the railing strut ,
  • the coupling element is hook-shaped, the hook opening extending at an angle of less than 90 ° with respect to the longitudinal axis of the rod, so that a hook nose formed thereby provides an undercut with respect to lifting vertically upwards forms.
  • the coupling elements are preferably arranged rigidly at the ends of the rod, which enables a particularly simple and robust design.
  • coupling elements in one piece with the rod, so that the manufacture is greatly simplified.
  • coupling elements mounted in several parts are also conceivable.
  • a metallic tube for the rod which is preferably flattened at the ends, the shape of a coupling element, e.g. B. the shape of a hook can be punched out. This leads to a particularly favorable stable and robust embodiment.
  • welded-on hooks or other hooks are also conceivable.
  • the railing is also advantageous to design the railing as a double railing, in which two rods are provided, so that railing rods can be mounted at different heights at the same time in a labor and time-saving manner.
  • the railing strut according to the invention has at least one receiving element for receiving a railing according to the invention, which is preferably arranged rigidly on the scaffold strut, for. B. by welding or the like.
  • a receiving element which has a plurality of locking receptacles for receiving a locking element, such as. B. has a locking hook of the coupling element. It is particularly preferred to provide the snap-in frames offset from one another by 90 °, since this enables the right-angled arrangement of a plurality of scaffold railings on a scaffold strut, which prevails in scaffolding construction.
  • several receiving elements at different angles to one another are of course also conceivable in order to enable oblique arrangements.
  • the receiving elements are designed as annular disks or rosettes, with corresponding latching receptacles or openings being provided in the disks, into which the coupling elements, for. B. in the form of hooks can intervene on the scaffolding railing.
  • the coupling elements for. B. in the form of hooks can intervene on the scaffolding railing.
  • other suitable shapes such as e.g. Temples, bags and the like, conceivable.
  • the railing arrangement is constructed in such a way that a first railing strut is first arranged in the railing arrangement. Then the railing with the coupling element at one end of the rod of the railing is aligned with the railing strut such that it corresponds to a first Position of the railing can be coupled to the first railing strut.
  • the railing with the coupling element which is connected to the receiving element of the first railing strut in a first position, is then pivoted into a second position, so that the railing is already securely and permanently arranged on the first railing strut.
  • a second railing strut is then aligned with respect to the railing in such a way that a first position is again assumed in which the other free end of the railing can be connected to the receiving element of the second railing strut.
  • the second railing strut is pivoted such that the railing and the second railing strut assume a second position in relation to one another in which they cannot be detached from one another. This position also corresponds to the arrangement position of the second railing strut in the railing arrangement.
  • Such a construction of a railing arrangement in particular in the case of scaffolding, also has the particular advantage that the railing must be attached at the same time as the scaffolding struts, so that the people who assemble the scaffolding are secured at a very early stage. This is particularly the case when scaffolding is used in which the scaffolding planks are only installed after the insertion of scaffolding struts projecting upwards, since a scaffold railing is then already present when a new work surface is created.
  • FIG. 1 shows the interaction of a scaffolding site with a scaffolding strut in a side view, the partial stages a) to c) showing the various stages for attaching the railing to the scaffolding strut;
  • Fig. 2 is an end view of a receiving element and
  • FIG. 3 is a side view of an installed railing between two scaffolding struts, the railing being in a self-locking state in that it cannot be removed;
  • FIG. 4 shows a side view (a) and a top view (b) of a further embodiment of coupling and receiving elements; and in the

  • the reference numeral 1 shows a scaffold railing which, although only shown for one side, has 3 coupling elements 4 in the form of a hook at the ends of a rod.
  • the rod 3 is preferably a hollow round rod, the hooks 4 being formed in one piece at the ends of the rod 3. This is preferably done by flattening the ends of the round rod 3 and punching out the hook-shaped shape of the coupling element 4.
  • the shape of the hook 4 with the hook opening or the hook mouth 6 and the hook nose 7 is selected such that the hook opening or jaw opening encloses an acute angle with the longitudinal axis of the rod, here at an angle of approximately 45 ° to the longitudinal axis of the rod 3 runs.
  • the end of the hook nose 7 forms an undercut 8 with respect to the inner region of the hook opening 6.
  • the hook mouth here is slit-like and delimited by parallel slit surfaces, which are designated in FIG.
  • the hook jaw tapers to an approximately V-shape, with one V-surface, namely the V-surface designated by 57, extending essentially parallel to the longitudinal axis 58 of the railing strut and the other V-surface 59 essentially is curved or rounded.
  • There is also a simple production-related production of the locking element Due to the inward toward the railing struts or hook lugs, there is a good engagement of the rosette 5 after hanging the locking element.
  • scaffolding railing 1 is clear from the sequence of the sub-images a) to c).
  • scaffold struts 2 are usually arranged one after the other in such a way that the complete scaffold is created.
  • the scaffold struts 2 can be present as individual struts or in the form of scaffold stands, frames or the like.
  • the attachment is carried out in such a way that the scaffold railing 1 is first arranged in a first alignment with the scaffold strut 2. In this orientation, it is possible to insert the coupling element in the form of the hook 4 into a receiving element 5 which is attached to the scaffold strut 2.
  • the receiving element 5 according to FIG.
  • the scaffold railing 1 which is designed here as an annular rosette, has four latching receptacles 9 in the form of rosette openings. If the scaffold railing 1, as shown in Fig. La, aligned so that the hook nose 7 can engage in a rosette opening 9, the edge of the rosette 5 moves into the hook opening 6, then the scaffold railing 1 with the scaffold strut 2 in one Insertion position. In the exemplary embodiment shown, the scaffold railing 1 must be aligned approximately at an angle of 45 ° to the longitudinal axis of the scaffold strut 2, since the hook opening is oriented at an angle of approximately 45 ° to the longitudinal axis of the rod 3.
  • the scaffolding railing 1 with the coupling element 4 in the receiving element 5 can be pivoted on the scaffolding strut 2, the scaffolding railing 1 can, as shown in FIGS. 1b and 1c, move from the insertion position (FIG. lc) be pivoted. In this secured use position of FIG. 1c, the scaffold railing 1 can no longer be lifted from the scaffold strut 2. This is achieved in that the undercut 8 of the hook nose 7 prevents detachment of the scaffold railing 1 in the vertical direction upwards, while the rosette 5 prevents displacement movements in the other spatial directions.
  • the scaffold railing 1 is now installed in a scaffold during installation such that the scaffold railing 1 is first connected to a scaffold strut 2 already arranged in the scaffold, as shown in FIGS. 1a to 1c.
  • a further scaffold strut is then arranged in the scaffold, the scaffold strut being initially connected at an appropriate angle to the scaffold railing 1 already arranged on one side in the scaffold in the insertion position, in order then to pivot the scaffold strut relative to the scaffold railing 1 and in the desired position to be installed in the scaffolding.
