Description

TECHNICAL AREA

The present invention relates to a railing post for a scaffold with scaffolding levels with vertical posts / vertical frames running in the longitudinal / vertical direction, cross bars running in the transverse / horizontal direction, railing posts, decks for the assembly of a so-called leading railing, by means of which at least one temporary, telescopic railing post is removed from an existing one lower scaffolding shelf can be assembled from for an upper scaffolding shelf to be mounted above, with a first connection device, a second connection device, a third connection device, the first connection device being arranged in the upper end region of the railing post, to which at least one temporary railing stile can be detachably connected third connection unit is arranged in the lower end of the scaffold post, which is detachable with existing components of the scaffolding, in particular with the vertical post with connected railing bars or a rosette of the Vertical post, is connectable, the second connection device is arranged at a distance in the longitudinal direction above the third connection device, which can be releasably locked to the vertical post of the scaffolding, a continuous rotatable shaft is arranged within the railing post, the rotatable shaft is connected to externally accessible rotary actuation devices, which are arranged in the upper and / or lower end area of the railing post and are movable in one direction, in particular rotatable in the direction of rotation, rotatable in one direction of rotation, the second connection device is a form-fit unit firmly connected to the railing post and a form-fit unit connected above or below or within the fixed form-fit unit movable, in particular rotatable, form-locking unit, which is movable from a closed position to a maximum open position and vice versa, with a form-locking locking of an inserted in the closed position Guided railing post is given on a vertical post of the scaffolding.

The present invention further relates to a scaffold with a leading railing with such railing rails and a method for moving a leading railing on an existing scaffolding.

As a rule, side protection with a handrail is only installed when the scaffolding erector is standing on the scaffolding level to be worked on. This is dangerous because the scaffold erector stands free at great heights without side protection and in the worst case can fall off the scaffolding. In order to increase safety, so-called leading railings are used, which guarantee side protection on the upper scaffolding level to be processed.

Such leading railings consist of a total of three individual components per scaffold bay, namely two identical railing posts that are connected to existing vertical posts of the scaffolding and to which at least one, in particular two telescopic railing bars are connected. The guardrail posts with the connected guardrails are assembled from the scaffolding level below and, due to their length, provide at least one-piece side protection in the next, upper scaffolding level. Depending on the progress of construction, another guardrail post of the leading guardrail is gradually moved upwards in order to secure the upper scaffolding level for further assembly work. The dismantling is done in reverse order.

STATE OF THE ART

From the DE 10 2009 024 816 A a railing post for a leading railing is known which has two scissor-like claws that have to be actively opened and closed for connection. A pin is used to lock and secure the lower area of the scissor-like claws. To ensure a positive fit, the outer tube of the railing post must be moved vertically, then rotated and then lowered again. The unlocking takes place in reverse order. A disadvantage of this leading railing is that an uncomfortable vertical and horizontal movement has to be carried out during the assembly and disassembly of the leading railing. In addition, it must be ensured during assembly that the upper and lower scissor-like claws are completely connected to the vertical frame or vertical post to be attached and also enclose it.

The EP 1 338 723 A2 discloses a device for assembling a temporarily existing handrail of a scaffolding, in which the third lower connection device is hung on existing handrail and the second connection device is connected to the handrail by means of a U-shaped receiving unit with a wedge unit.

The EP 1 571 275 A2 discloses a device for mounting a temporarily existing handrail post with connected telescopic handrail rails to existing vertical posts of a scaffolding according to the features of the preamble of claim 1. The handrail post has claws with an automatic clamping function, with a continuous rotatable shaft inside the Railing post is used, which can be rotatably actuated via actuating units and is connected to the claws via a relatively complex mechanism. By rotating the actuating unit, the vertical post must be actively opened and closed to connect the railing post. To do this, the actuation unit is rotated accordingly. A disadvantage of this solution is that a rotary movement has to be actively carried out during assembly and disassembly of the leading railing. In addition, the internal mechanism is relatively complex and prone to damage. In addition, it must be ensured during assembly that the upper and lower claws are fully connected and locked into place on the vertical frame or vertical post to be attached.

A further method according to the invention for moving a leading railing on a facade or modular scaffolding with the above-described railing posts connected to vertical posts from an existing secured scaffolding level for a further scaffolding level to be mounted and secured above is characterized by the following process steps:

• - Detaching the second connection device from the vertical post,
• - tilting the railing post outwards,
• - Lifting the railing post in the longitudinal direction upwards to detach the third connection device from the vertical post,
• - further lifting of the guardrail post in the longitudinal direction upwards until the height of the existing guardrail is reached,
• - Attaching the third connection device at the level of the rosette with connected existing handrail bars by inserting the, in particular curved, projection unit into a recess in the rosette or at the level of the connection of the existing handrail bars to the vertical post by hanging the second connection area with the recesses in the existing handrail bars,
• - Tilting of the railing post in the direction of the vertical post of the scaffolding to connect the railing post to the vertical post via the second connection device,
• - Connecting the second connection device to the vertical post.

With the railing post according to the invention shown, a quick-to-assemble and robust railing post is available for a leading railing, which in a first construction has a second connection device with a wedge-shaped or U-shaped tube receptacle for the vertical post, which is connected by a simple mechanism (snap mechanism with torsion spring) automatically opens when pressed against the vertical stem and then closes again immediately as soon as the vertical stem has reached its end position and is completely enclosed by the rotatable form-fitting unit. A simple rotary movement of the rotary actuation devices opens the second connection device with its rotatable form-fit unit and the railing post can be moved. One advantage here is that the handrail post is automatically secured, but the assembly person is actively involved Moving the leading railing must unlock via the actuation device. This saves a lot of time during assembly, since threading into receiving devices or connection devices, as in the prior art, is no longer necessary, or fewer steps are required for assembly than before. The rotatable interlocking unit is connected to the two rotary actuation devices by the rotatable shaft in the outer tube of the scaffolding post, so that the railing post can be secured and unlocked on both actuation devices both in the upper and in the lower area. The existing elastic element (torsion spring) guarantees a reliable locking of the railing post via the second connection device on the vertical post.

The third connection device in the lower part of the guardrail post is used for optimal assembly to the guardrail connection of a system frame, for example a Layher SpeedyScaf ^® (registered trademark) system and / or to the rosette of a vertical standard, for example a Layher Allroundgerüst ^® (registered trademark) system . The third connection device is simply placed on or hooked in and is secured against displacement by precisely fitting recesses.

An alternative according to the invention railing post for a module frame (Layher round scaffold ^® (registered trademark)) has a third connection means at only a first connection area is present, the lower side has a curved profile unit. The first and second connection devices can be designed in any way and only need to fulfill the desired functionality, i.e. temporary handrails must be releasably connectable to the first connection device and the second connection device must be releasably lockable on the vertical post.

Further embodiments and advantages of the invention result from the features also listed in the claims and from the exemplary embodiments given below. The features of the claims and the exemplary embodiments can be combined with one another in any way, provided that they are not obviously mutually exclusive.

WAYS OF CARRYING OUT THE INVENTION

In 1 is a first embodiment of a railing post 10.1 shown, which is used in the context of a leading railing on a facade scaffolding such as the Layher SpeedyScaf ^® (registered trademark) system. The railing post 10.1 is designed as a round tube. The length of the railing post 10.1 is in 1 with the reference number L. and those perpendicular to the longitudinal direction L. transverse direction is in 1 with the reference number Q specified.

The railing post 10.1 has a first connection device in its upper end region at a distance from the end face 12.1 to which two telescopic temporary handrail bars can be detachably connected on both sides.

Above the third connection device 16 is a lower rotary actuator 22.2 , designed as a rotary handle, in the direction of rotation D. rotatable and with the in 1 rotatable shaft not shown (reference number 18th please refer 11 ) connected is.

Above the lower rotary actuator 22.2 is a second connection device 14th connected, also in the transverse direction Q protrudes and a rotatably connected Form-fit unit 24 and a rotatable to the rotatable shaft 18th connected form-fit unit 26th having.

In 2 is a second embodiment of a railing post 10.2 shown, which is used as part of a leading railing in a modular scaffolding, in particular a Layher Allround ^{Scaffolding ®} (registered trademark) system. This railing post 10.2 has substantially the same lower and upper rotary actuator 22.1 , 22.2 , the same second connection device 14th and the same third connection device 16 as they do with the railing post 10.1 according to 1 is available. The same components have the same reference symbols and are not explained again. A difference to the railing post 10.1 is that the first connection device 12.2 as a protrusion unit 76 with a toggle pin 74 is designed for the detachable connection of the telescopic temporary railing bars. The further first connection device 12.2 below the upper rotary actuator 22.1 is also as a protrusion unit 76 with tilt pin 74 educated.

Finally, by the railing post 10.2 additionally between the further first connection device 12.2 and the second connection device 14th one in the transverse direction Q running connected safety stop unit 32 available.

The third connection device 16 is in 3 shown in more detail. On the railing post 10.1 respectively 10.2 is first one in the transverse direction Q running first connection area 34 integrally formed, the one downward projection unit 38 owns. To the first connection area 34 is a transverse Q running second connection area 36 connected, the one seen in a plan view U-shaped receiving unit 48 with two legs, both legs having a downwardly open U-shaped recess on the underside 40 exhibit.

The U-shaped receiving unit 48 has a semicircular inner contour in its base.

The second connection device 14th is in the 8th to 12 shown in more detail. The second connection device 14th has one firmly attached to the railing post 10.1 , 10.2 connected in the transverse direction Q protruding fixed form-fitting unit 24 on which an outwardly open U-shaped recess 35 with protrusion units arranged on both sides 33 having the inner base of the U-shaped recess 35 a part-circular inner contour, in particular a semicircular inner contour 25th , having. This inner contour 25th has a radius of curvature which essentially corresponds to the radius of curvature of the outer circumferential contour of a vertical post of a frame to be connected.

Slightly spaced above the fixed form-fitting unit 24 is a rotatable form-fitting unit 26th connected as in 10 represented by a connecting pin 44 that is in a slot 42 the outer wall of the railing post 10.1 , 10.2 is guided to the rotatable shaft 18th (please refer 11 ) connected.

The rotatable form-fit unit 26th is in its front end area as a hook unit with a part-circular inner contour 27 formed, whose radius of curvature is essentially the radius of curvature of the outer contour of the railing post 10.1 , 10.2 corresponds. In the front end region of the hook unit, it has an inclined end contour 51 on.

Between the fixed form-fit unit 24 and the rotatable interlocking unit 26th is an elastic element 28 arranged, which is designed as a torsion spring and with both form-fitting units 24 , 26th connected is.

By guiding the connection unit 44 in the slot 42 is the maximum rotational movement D. the rotatable interlocking unit 26th limited. Furthermore, is on the fixed form-fitting unit 24 a stop unit 30th molded onto which the rotatable form-fit unit 26th in closed position according to 8th and due to the action of the elastic element 28 strikes. In the closed position, the inclined front end contour forms 51 the rotatable interlocking unit 26th together with the inner contour of a projection unit 33 the first form-fit unit 24 seen in a plan view a V-shaped recess in which the vertical post of the scaffolding is initially attached during assembly.

Used on the inclined final contour 51 a compressive force in the transverse direction Q towards the railing post 10.1 , 10.2 applied, for example by pressing the second connection device 14th on a vertical post of a scaffolding, the rotatable form-locking device opens against the action of the elastic element 28 . As soon as the pressed vertical stem reaches the bottom of the U-shaped recess 35 , that is, the part-circular contour 35 reached, the rotatable form-fit unit snaps 26th due to the action of the elastic element 28 back into the closed position, whereby the inserted vertical handle is positively encompassed and is securely locked in its inserted position.

The 9 shows the rotatable interlocking unit 26th in the open position, which can be obtained by turning the Rotary actuator 22.1 in direction of rotation D. is achieved. In this position, the vertical post can be detached from the second connection device.

The 4th shows in detail the connection of the second connection device 14th of the railing post 10.1 to a facade scaffolding with a vertical post 58.1 , on which a gusset plate 64 a crossbar 60.1 is connected, in which decks for walking on the scaffolding floors are suspended during the construction of the scaffolding. The second connection device 14th is immediately below the gusset plate 64 to the vertical post 58.1 connected, allowing movement of the handrail post 10.1 longitudinal L. upwards is prevented that the second connection device 14th on the underside of the gusset plate 64 strikes.

In 5 is the connection of the third connection device 16 to the vertical post 58.1 a facade scaffolding, which can be, for example, the well-known Layher Blitz Gerüst ^® (registered trademark) system. On the vertical handle 58.1 is a railing box 78 connected, in which, in turn, existing handrails 68 of the scaffolding are releasably connected. The third connection device 16 is with its second connection area 36 over the U-shaped recess 40 from above on both sides in the connection area of the existing handrails 68 to the vertical post 58.1 hooked in, with the vertical stem 58.1 between the two legs of the U-shaped receiving unit 48 in contact with the part-circular inner contour of the base of the receiving unit 48 penetrates.

In 6th is the connection of the second connection device 14th on a vertical post 58.2 of a modular frame. On the vertical handle 58.2 are in a longitudinal direction L. predetermined grid rosettes 66 with connection recesses available. Such a modular scaffolding for example, the known Layher Allround scaffolding ^® (registered trademark) - his system.

The safety stop unit 32 is arranged so that it is directly below a rosette 66 is present, i.e. the railing post 10.2 longitudinal L. can practically not be moved upwards, as the safety stop unit 32 to the rosette 66 strikes.

In 7th is the connection of the third connection device 16 to the vertical post 58.2 shown. The first connection area 34 is with its protrusion unit facing downwards 28 in a recess in the rosette 66 hung and the vertical stem 58.2 runs through the U-shaped receiving unit 48 .

In 13 is the first connection device 12.1 shown in more detail.

The first connection device 12.1 is designed as a fork-shaped construction with two parallel spaced apart projection units 76 , each with a connection unit in its free end area 72 with a toggle pin 74 for the detachable connection of a temporary, telescopic handrail of a leading handrail. The clear interior distance A. the protrusion unit 76 is larger than the outer diameter of the vertical stem 58.1 , 58.2 of the scaffolding. The projection units 76 are also provided by an inwardly offset crosspiece 75 connected with each other.

The construction shown enables the connection units 72 the first connection device 12.1 with the railing post connected 10.1 can be arranged significantly closer to the scaffolding or scaffolding decking, in contrast to the known connection devices in which the temporary guardrail is connected on the outside in front of the vertical post. In this way it can be achieved that in the connected state the distance between the inner contour of the temporary handrail spar 20th When viewed from the outer contour of the covering or a toe board in a plan view, it does not exceed a permissible dimension of, for example, 80 mm.

The 14th to 19th show the use of the railing post 10.1 as part of a leading railing in different assembly positions on a facade scaffolding such as the Layher SpeedyScaf ^® (registered trademark) system. The facade scaffolding 50 has vertical frames 56 with parallel vertical posts spaced apart in the transverse direction 58.1 on, which in the upper end area each have a gusset plate 64 with a crossbar 60.1 are connected. In the lower end area connects the two vertical posts 58.1 a transverse profile 70 .

As in 14th shown is the railing post 10.1 initially with its third connection device 16 from above in the connecting area of the existing handrails 16 to the vertical post 58.1 into the existing handrails 68 suspended and is initially in an outwardly inclined position in which the second connection device 14th with their rotatable form-fit unit 26th on the outer contour of the vertical post 58.1 is applied. By pressing the railing post further 10.1 in the direction of the vertical post 58.1 the rotatable form-fit unit opens 26th until the in 15th shown vertical end position of the railing post 10.1 is reached. The rotatable form-fit unit snaps into this position 26th due to the action of the elastic element in the closed position and the vertical stem 58.1 is through the second connection device 14th positively enclosed and thus locked. In the 14th and 15th the detachably connectable telescopic handrail bars of the leading handrail are not shown.

In the 15th Connection situation of the railing post shown 10.1 on the vertical stalk 58.1 corresponds to the connection of the second connection device 14th according to the detailed representation 4th and with respect to the third connection device 16 according to the detailed representation 5 .

The 16 to 19th show the use of the railing post 10.1 as part of a leading railing with the first two connection devices 12.1 connected telescopic handrails 20th in different assembly positions in a scaffolding bay ( 16 to 19th ) and in three scaffolding bays ( 18th and 19th ).

16 shows an intermediate assembly state of a scaffolding bay of a lower floor 54 of the scaffolding 50 , where the left handrail post 10.1 is still in a lower assembly position and the right handrail post 10.1 already in its end position to secure an upper scaffolding level 52 connected. The 17th shows the state in which the left handrail post is also shown 10.1 connected in the (temporary) upper position.

18th shows the state of a connected leading railing with three scaffold bays of the scaffold 50 according to the assembly state of 17th .

19th shows the further assembly progress based on the state according to FIG 18th . So after assembly of the leading railing according to 18th Toppings 62 into the crossbars 60.1 the vertical frame 56 hooked so that the upper scaffolding levels 52 can be entered by the assembly staff, while at the same time a side protection through the leading railing with its railing posts 10.1 and the temporary handrails 20th given is. Then, as in 19th shown on the vertical frame 56 the lower scaffolding days 54 Vertical frame 56 attached, with the railing posts then with regard to the further assembly progress 10.1 successively at the level of the upper scaffolding levels 53 be moved so that a side protection is provided for another scaffolding to be assembled.

In 20th is the connection of a railing post 10.2 to the vertical post 58.2 a modular scaffolding, for example the Layher Allroundgerüst ^® (registered trademark) system. In the 20th shown connection situation of the second connection device 14th corresponds to the detailed display of 6th and the connection situation of the third connection device 16 corresponds to the detailed display of 7th .

The modular framework consists of two parallel spaced vertical posts 58.2 with in the longitudinal direction L. Rosettes arranged in a grid 66 with recesses in the upper and lower end areas via crossbars 60.2 are connected to one another via a wedge head connection, in the longitudinal direction of the scaffolding 50 Longitudinal bar 63 to the rosettes 66 in the upper and lower end area of the vertical stem 58.2 are connected. In the middle are the rosettes 66 existing handrails 68 connected.

The 21st shows a third embodiment of a railing post 10.3 , which basically has the same structural design as the railing post 10.2 according to 2 , but with the following differences. The railing post 10.3 does not have a safety stop unit 32 on and the third connection device 16 - shown in more detail in 22nd - differs from the third connection device according to 3 in that a projection unit 38.1 longitudinal L. pointing downwards to the first connection area 34 is formed, which is designed as a curved profile unit, wherein the curvature contour is designed so that the free end region of the projection unit 38.1 to the railing post 10.3 is curved towards present. The same components have the same reference symbols and are not explained again.

The railing post 10.3 has the advantage that it can be used both with facade scaffolding (Layher Blitz Gerüst ^® (registered trademark) system) and with modular scaffolding (Layher Allroundgerüst ^® (registered trademark) system). The assembly or disassembly on a vertical stick 58.1 , 58.2 a scaffolding 50 takes place in the manner described above in the same way as for the railing posts 10.1 respectively 10.2 .

When assembling the railing post 10.3 on a vertical post 58.1 with rosettes 66 becomes the curved projection unit 38 threaded into a recess in the rosette, then the railing post 10.3 spent in vertical position and the second connection device 14th to the vertical post 58.1 connected. The railing post is in this final assembly position 10.3 secured against lifting up in the longitudinal direction / vertical direction, since the curved projection unit 38.1 blocks movement upwards.

Lifting the railing post out of the rosette 66 is only possible if the second connection device 14th is actively resolved and the Railing post is inclined accordingly so that the curved contour of the projection unit can be moved out of the recess of the rosette.

In 25th Figure 3 is a fourth embodiment of a handrail post 10.4 shown, which basically has the same structure as the railing post 10.3 according to 21st , but with the difference that there is no second connection area 36 at the third connection device 16 is present, but this only from the first connection area 34 with a curved projection unit molded on the underside 38.1 having. Such a railing post 10.4 is suitable on a vertical stick 58.2 a modular scaffolding (Layher Allroundgerüst ^® (registered trademark)). The assembly process is carried out in the same way as for the assembly process described above.

The same components have the same reference symbols and are not explained again.

An embodiment variant not shown relates to an alternative structurally different configuration of the railing post 10.3 , not including the in 25th illustrated first connection device 12.2 and second connection device 14th is used and with respect to the second connection device 14th on the rotary controls 22.1 respectively 22.2 and the rotatable shaft is dispensed with. The structural design of the first and second connection devices 12.2 , 14th only needs to be designed in such a way that they meet the required functionality, that is to say that of the first connection device 12.2 temporary handrails are releasably connectable and the second connection device 14th is releasably lockable can be connected to a vertical stem.
