Definitions

  • the present invention relates to a front end for a leading railing and a method for assembling a front end of a leading railing, as well as a scaffold comprising a front end according to the preambles of the independent claims.
  • Leading railings of scaffolding are known. These are characterized by the fact that a scaffolding railing can be installed by a user or scaffolder who is on a lower scaffolding level or on the ground. Accordingly, the user is secured by the railing in front from the moment they enter the upper scaffolding level for the first time.
  • Such leading railings are already known, which lock themselves automatically during assembly, so that the railings are already secured during the preliminary assembly. A corresponding step when entering the upper scaffolding level for the first time can be omitted. This significantly reduces the risk of an accident.
  • end caps This is a longitudinal end of a scaffolding, which inevitably occurs with a non-circulating scaffolding. With such front ends there is also the problem that the space required on the lower scaffolding level is limited, so that the front end has to be assembled by a single person during preliminary assembly.
  • the known end caps are either not suitable for preliminary assembly or are bulky and can only be assembled with great effort by one person.
  • a front end for a leading railing a method for assembling such a front end and a railing with a corresponding front end are to be provided.
  • a front end according to the invention for a leading railing of a scaffold for mounting between two vertical tubes of a scaffold, preferably between two vertical tubes of a vertical frame of a scaffold, comprises two vertical supports, an end rail and an access barrier.
  • the two vertical supports are arranged essentially parallel to one another and at a distance from one another. This distance has a distance which is variable in such a way that the distance between the two vertical supports during assembly of the end cap is smaller than in the assembled state of the end cap.
  • variable distance between the two vertical supports of the front end makes handling the front end much easier.
  • the space for providing the components for the next higher scaffold level is limited, so smaller elements or end caps with a reduced width are much easier to use.
  • forehead ends with reduced Distance between the two vertical supports can be stored and transported more easily and in a space-saving manner.
  • the vertical tubes of the scaffold are preferably part of a vertical frame, i.e. a modular element, a scaffold.
  • a vertical frame i.e. a modular element, a scaffold.
  • such a vertical frame can also include at least one horizontal tube, which connects the two vertical tubes to one another.
  • the front end can be assembled and/or dismantled without tools. Accordingly, assembly and/or disassembly on the scaffolding is simplified. There is no need to carry tools with you.
  • the vertical supports can be lockable in such a way that the distance between the vertical supports is fixed. This means that the end cap cannot unintentionally become detached from the vertical tubes of the scaffolding. The risk of accidents on scaffolding is significantly reduced.
  • Locking the vertical supports can be done using a front toe board.
  • a receptacle can be provided at the front end, which can accommodate the front toe board, so that a relative movement between the vertical supports is prevented.
  • the receptacle for the front toe board can be formed by two locating pins that are arranged vertically at the lower end of the front end when used as intended. These locating pins are preferably arranged on the vertical supports.
  • the vertical supports can each have a projection at their lower end directed towards the opposite vertical support have, on each of which a receiving pin is arranged.
  • the two vertical supports can each be provided with at least one, preferably two or more, stops for receiving the vertical tube. These stops make it easier to position the end cap correctly and at the same time serve to attach the end cap to the vertical tubes of the scaffolding.
  • the stops preferably protrude laterally on the end of the forehead.
  • the stops can be designed in the form of U-shaped retaining clips. Accordingly, these are designed simply and can at least partially surround a vertical tube.
  • the stops of the first vertical support can be arranged offset from the stops of the second vertical support in their installation height, so that when several end caps are stored next to each other, the stops do not touch each other.
  • the retaining clips arranged at the bottom when used as intended can each have different leg lengths. This makes it possible that when installing the end cap, the upper retaining clips first have to be aligned with the corresponding vertical tubes. These can then already engage in the vertical tubes, while the lower retaining clips do not yet have to be aligned with the vertical tubes. By tilting the front end, the lower retaining clips are then aligned with the vertical tubes. This makes installing the front end much easier.
  • the vertical supports can have a support element at their lower end when used as intended for support on a horizontal tube of the scaffolding, in particular the vertical frame of the scaffolding.
  • Such support elements in turn make it easier to assemble the front end, since the weight of the front end can be supported on the scaffolding in order to align the front end.
  • the support element is attached to the same projection of the vertical support to which the receiving pin for receiving the front toe board is attached.
  • the support element can be U-shaped. Placing the front end on the horizontal tube of the scaffolding is made even easier. In addition, a U-shaped support element makes it easier to move the vertical support laterally in order to reduce or increase the distance to the second vertical support.
  • the vertical support can be designed like a telescope.
  • a support tube can form the lower area of the vertical support, while the upper area is formed by a support insert that is slidably mounted in the support tube. It is also conceivable that the lower region of the vertical support is slidably mounted in the upper, tube-like region of the vertical support.
  • a telescopic design allows, for example, a flexible adjustment of the height of the vertical support and thus also an adjustment of the height of the end bar.
  • the stops for receiving the vertical tube can be arranged exclusively on the upper area, exclusively on the lower area or on both areas of the vertical support.
  • the access barrier can have two intersecting barrier struts, which are preferably connected in the middle with a scissor joint. By connecting with a scissor joint, the access barrier can adapt to the respective distance between the vertical supports. The space between the vertical supports is therefore blocked at all times.
  • the locking struts can be arranged in an articulated manner on the vertical supports.
  • the locking struts are only connected to the vertical supports at their upper or lower end when used as intended.
  • the locking struts are connected in an articulated manner to one and the other vertical support at both their upper and lower ends.
  • either the vertical supports or the locking struts between their attachment points must be designed to be telescopic.
  • the end bar can be foldable and is preferably provided with a swivel joint in the middle. This configuration allows the different distances between the vertical supports to be bridged during assembly or after assembly. It is also conceivable that the end bar is designed to be telescopic.
  • end bar is foldable, it is preferably connected to the vertical supports in an articulated manner.
  • a foldable design has advantages both when assembling and dismantling the front end. If the front end is provided with a reduced distance before assembly, the end bar that is folded up or deflected upwards has a tendency to push the two vertical supports apart due to its gravity during assembly, so that the stops accommodate the vertical tubes. The vertical supports only need to be locked accordingly.
  • the end bar will pull downwards due to gravity and thus tend to reduce the distance between the vertical supports. As soon as the locking of the vertical supports is released, they can simply be pushed together so that the stops no longer engage in the vertical tubes.
  • the swivel joint of the end bar can be locked with a joint lock.
  • a pipe socket is pushed over the area of the swivel joint so that the swivel joint is blocked.
  • a telescopic end bar can also be lockable, for example by a locking pin.
  • the vertical support can have a handle at its lower end when used as intended for grasping the end of the forehead.
  • Both vertical supports are preferably each provided with a handle.
  • This handle is designed in such a way that the front end can be mounted in advance over the head. For example, when used as intended, this handle protrudes downwards from the vertical support. However, it is important to ensure that the grab handle does not collide with either a vertical tube or a horizontal tube of the scaffolding.
  • a further aspect of the present invention relates to a framework comprising at least one front end as described above.
  • the Figure 1 shows a perspective view of a scaffold 1 with three levels.
  • the levels are formed by inserting vertical frames 2 into one another, the vertical frames 2 essentially consisting of two vertically arranged tubes which are connected to a horizontal tube.
  • Each level is defined by a scaffolding deck 5, which serves as a standing area for the workers.
  • railing bars 6 are attached to the vertical frame 2.
  • each scaffolding level has two railing rails 6.
  • the number and height position of the railing rails 6 is usually determined by national safety standards. Such safety standards also require that a toeboard 7 must be present next to the scaffolding deck 5. It is also required that a side end of the scaffolding 1 must not remain open, but must be closed off with a front end 10. The front end 10 must also have a front toe board 24 connected to the scaffolding deck 5.
  • FIG 2 A front end 10 according to the invention is shown in a perspective view in the framework 1 Figure 1 . It can be seen that the front end 10 is inserted between vertical tubes 3 of the vertical frame 2.
  • the front end 10 essentially has two laterally arranged vertical supports 11, which, when used as intended, are connected at their upper end by means of an end bar 14.
  • the end rail 14 is located essentially at the height of the upper railing rail 6.
  • the front end 10 also has an access barrier 17, which covers the space between the vertical supports 11 and the end rail 14 and the scaffolding deck 5 blocked.
  • the access barrier 17 is formed by two barrier struts 18, which cross each other in the middle and are articulated to the vertical supports 11 at both ends.
  • retaining clips 20 are formed on the sides of the vertical supports 11 of the end cap 10. These retaining clips 20 are U-shaped so that they can accommodate a vertical tube 3 between the two legs of the U-shape.
  • the front end 10 shown has two retaining clips 20 for each vertical support 11, each vertical support 11 having a retaining clip 20 in the lower region and a retaining clip 20 in the upper region of the vertical support 20. Thanks to the two retaining clips 20, the front end 10 is already securely clamped between the two vertical tubes 3 of the scaffolding 1 and reliably protects against a fall.
  • the front end 10 has two support elements 21 at its lower end.
  • One support element 21 is attached to a vertical support 11 and is in turn designed to be U-shaped so that it can be placed on a horizontal tube 4 of the scaffold 1.
  • the assembly of the end cap 10 becomes independent of fastening elements on the vertical tube 11.
  • fastening elements on the vertical tube 11 are usually present, they are often already used, for example for fastening railing rails 6.
  • the horizontal tube 4 is usually on one Scaffolding 1 is present and is used as a support for the elements of the scaffolding deck 5.
  • the front end 10 has two handles 22 at its lower end, which protrude laterally from the vertical supports 11 and extend obliquely downwards. These handles allow a user to lift the front end 10 from a lower scaffolding level overhead to the next higher scaffolding level and to insert it between the vertical tubes 3 present there. Accordingly, the user can move on an already secured level of the scaffolding 1 and mount the front end 10 of the next higher level.
  • the end bar 14 is foldable, designed with a centrally arranged swivel joint 15 and connected in an articulated manner to the two vertical supports 11.
  • the access barrier 17 with its two locking struts 18 is also articulated to the vertical supports 11, with the locking struts 18 being connected to one another in the middle via a scissor joint 19.
  • the vertical supports 11 are designed telescopically.
  • a lower region of the vertical support 11 is formed by a support tube 12.
  • a support insert 13 is slidably mounted in this support tube 12 and forms the upper region of the vertical support 11.
  • the locking struts 18 are each articulated at their upper ends to the support insert 13, while their lower ends are articulated to the support tube 12.
  • a front toe board 24 can be inserted in the lower area of the front end 10 between the vertical supports 11.
  • the front toe board 24 has the same height as that which is already adjacent to the scaffolding deck 5 mounted toe board 7.
  • the front toe board 24 can, for example, be inserted into a receptacle of the front end 10 so that it is stuck in a correct position.
  • the front toe board 24 can also be safely inserted from the lower scaffold level into the front end 10 arranged above it. Accordingly, the front end 10 can be assembled completely in advance and already secured. A worker can then enter the new scaffolding level, which already has a completely secured front end 10. To additionally secure the front end 10, the end bar 14 can also be secured.
  • a joint lock 16 which is, for example, tubular and can be pushed over the swivel joint 15 of the end bar 14.
  • the swivel joint 15 is thus blocked and the end bar 14 can no longer be folded.
  • the front end 10 is therefore still locked even after the front toe board 24 has been removed.
  • the Figure 3 shows the front end 10 according to the invention Figure 2 in a view from the front with a front toe board 24 shown in perspective, the front toe board 24 not being inserted.
  • the distance D between the two vertical supports 11 can be seen, which can be reduced to assemble the end cap 10.
  • the front toe board 24 can be inserted into the support end 10, as already stated.
  • the front toe board 10 has two locating pins 23, one locating pin 23 being arranged at the lower end of the vertical supports 11 on a projection projecting from the vertical support 11 in the direction of the other vertical support.
  • the receiving pins 23 are aligned parallel to the vertical supports 11.
  • the front toe board 24 has corresponding receiving holes 25, so that the front toe board 24 can be plugged onto the receiving pins 23.
  • the length of the locating pins 23 preferably corresponds to the depth of the locating hole 23, so that it is easy to see during assembly whether the front toe board 24 is correctly assembled.
  • FIG 4 is a perspective view of a retaining clip 20 on a vertical support 11 of the front end 10 Figure 2 shown.
  • the retaining clip 20 is U-shaped and has two legs, the leg lengths L1, L2 of which are different in the example shown. These different leg lengths L1, L2 make it possible to insert or locate the vertical tubes 3 (see Figure 2 ) significantly simplified when installing overhead.
  • the leg with the longer leg length L2 can be used to strike the vertical tube even before the retaining clip 20 effectively encompasses the vertical tube.
  • Not all retaining clips 20 of the front end are necessarily designed the same.
  • the upper retaining clips are each provided with two longer legs, while the lower retaining clips have legs with different leg lengths L1, L2.
  • the U-shaped retaining clip 20 can be arranged directly on the vertical support or, as shown in the illustration, can be connected to the vertical support 11 via a spacer element.
  • FIGS 5a and 5b show the front end 10 according to the invention Figure 2 ready for assembly ( Figure 5a ) on the scaffolding and after its dismantling ( Figure 5b ) from the scaffolding.
  • the distance between the vertical supports is reduced, so that the end bar 14 is folded up or down.
  • a flap up, as in Figure 5a shown is particularly advantageous for the assembly of the front end 10, since the gravity of the end bar tends to push the two vertical connectors apart. Accordingly must Less force must be used to increase the distance between the vertical supports so that the retaining clamps can engage in the vertical tubes of the scaffolding.
  • the gravity of the end bar 14 helps to move the vertical supports against each other and reduce their distance from one another.
