Description

TECHNICAL AREA

The present invention relates to a railing device Railing device for a scaffold with scaffolding levels with spaced vertical posts in the width direction, cross bars connected to the vertical posts in the transverse direction, coverings connected to the cross bars in the width direction, the railing device being designed as a so-called leading railing device, which is from an existing one lower scaffolding is assembled from for an upper scaffolding to be mounted above and which then forms a side protection for the upper scaffolding, which has at least one first handrail extending horizontally in the width direction, one connected in an end area of the first handrail, in particular extending essentially vertically in the vertical direction , right handrail post, a left terrain connected in the opposite end area of the handrail, in particular extending essentially vertically in the height direction rstiel, the first railing post having a first connection device in its lower end region and a second connecting device arranged at a distance above, each for detachable connection to a vertical post of a scaffolding, the left handrail post in its lower end region a third connecting device and one spaced above the third connecting device arranged fourth connection device, each for detachable connection to a vertical post of a scaffold.

The present invention also relates to a method of assembling a railing device.

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 usually consist of three or four 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, a further railing post of the leading railing is always successively moved upwards into the railing device 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, a continuous rotatable shaft is used inside the handrail post, which over Actuating units can be operated rotatably 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 used during assembly care must be taken that the upper and lower claws are fully connected and locked in place on the vertical frame or vertical post to be attached.

The DE 103 05 158 A1 discloses a leading handrail in which the handrail and handrail posts are inextricably linked and the leading handrail thus forms a component. This leading railing is connected in the area of a gusset plate of an existing railing and to an already mounted upper railing of the scaffolding. The railing is secured in all directions due to holding devices. This leading railing has no stiffening effect and is only used as a temporary side protection during the construction and dismantling phase. Railings and diagonals are still required for the scaffolding. Use is not absolutely necessary for the assembly process.

Furthermore, a railing device is known as a leading railing in which the railing posts and railing bars form a frame structure. During assembly, the leading railing is hung on horizontal profiles, for example U-crossbars, of the scaffolding and then the vertical scaffolding tubes are attached to the vertical posts of the scaffolding by means of a clip connection. This leading railing remains in the scaffolding and has a stiffening effect due to its frame construction, which means that diagonals and individual additional railings in the scaffolding are superfluous. The railing is essential for the assembly process and cannot be removed afterwards. This leading railing has a relatively large number of struts, which is not optimal in terms of economical production and transport.

WAYS OF CARRYING OUT THE INVENTION

The railing device shown in the figures 10 is represented within an orthogonal frame of reference that has a vertical horizontal direction H , a horizontal width direction perpendicular thereto B. and one perpendicular to the width direction B. running transverse direction Q having. The railing device 10 has one in the width direction B. running first handrail 12 and one in elevation H with the distance GA arranged second handrail 14th on. The distance GA is selected so that the required safety standards are met. At the right end of the first and second handrail 12 , 14th is one in height direction H from the first handrail 12 right handrail post running downwards 16 and in the left end area a left handrail post 18th arranged. In the middle of the two handrails 12 , 14th is a vertical center vertical bar 28 connected.

The components shown form a rigid frame structure.

In the lower end of the right handrail post 16 is a first connection device 20th and at a vertical distance A1 above a second connection device 22nd arranged.

In the lower end of the left handrail post 18th is a third connection device 24 and above at a vertical distance A2 a fourth connection device 26th arranged.

In 2 is also the height level at which the second connection device 22nd to the first handrail 12 and the fourth connection device 26th to the left railing post 18th With H1 designated. Both connection devices 22nd , 26th are at the same height H1 . The height level of the first connection device 20th is in 2 With H2 and the level of the third connection device 24 with the reference number H3 Mistake. The difference between the height level H2 and the height level H3 corresponds essentially to the height of the third connection device 24 .

The selected height levels enable the second connection device 22nd and the fourth connection device 26th at the same height from both sides on a vertical post 58 can be connected (see 11 ) and the third connection device 24 when connecting to a vertical post 58 directly below the first connection device 20th is arranged (see 11 ).

The 3 shows the on the right hand rail 16 connected second connection device 22nd . This has one in the plane B. , Q arranged base plate 40 on, to the parallel spaced on both sides in the width direction B. extending projection units, namely a first projection unit 30th and a second protrusion unit 32 , are connected.

The projection units 30th , 32 stand over the end of the base plate 40 in width direction B. above and in the protruding area of the first projection unit 30th is a hanging recess that is open at the bottom 44 present, by means of which the second connection device 22nd when mounting in a crossbar of a scaffolding 50 can be attached (see for example 12 and 13 ).

The first projection unit 30th is on the inside of the vertical post 58 and the second protrusion unit 32 on the outside of the vertical post 58 arranged (see 7th ).

In the 4th fourth connection device shown 26th is a mirror image of the transverse direction axis Q to the second connection device 22nd educated. The same components have the same reference symbols and are not explained again.

How out 7th the second connection device can be seen 22nd and the fourth connection device 26th with one in the transverse direction Q running offset V to each other on the right or handrail post 16 , 18th connected, with the offset V the cross-sectional thickness of the first and second projection units, respectively 30th , 32 corresponds.

The clear inner distance between the first and second projection unit 30th , 32 is with AV in 7th marked. It essentially corresponds to the sum of the outer diameter D of the vertical post 58 and the offset V . This makes it possible for the second connection device 22nd and the fourth connection device 26th - as in 7th shown - each side opposite on the scaffolding 50 on the crossbar 60 can be hooked, at the same time the outer contour of the vertical stem 58 on the first projection unit 30th the second connection device 22nd and the second protrusion unit 33 the fourth connection device 26th on the inside. Furthermore, the two first projection units are in the assembled state shown in the figure 30th and the two second projection units 32 the second and fourth connection device 22nd , 26th directly to one another, so that a relative displacement of the connection devices 22nd , 26th in the transverse direction Q is blocked.

In 5 is the first connection device 20th shown as a hook on the right handrail post 16 connected. The suspension claw initially runs in the width direction B. and goes into a curved end area 48 about, which has a concave semicircular inner contour 46 has, which is essentially the curvature of the outer contour of the vertical stem 58 corresponds.

At the same time forms the end area 48 an insertion recess due to its curvature 49 into which the vertical support is installed 58 of the scaffolding 50 can be introduced.

The assembled state of the first connection device 20th is in 8th shown. It can be seen that the end area 48 the first connection device 20th the outer contour of the vertical post 58 surrounds positively in areas.

The third connection device 24 that is in the lower end of the left handrail post 18th connected to this, has one in the plane B. , Q arranged base plate 42 on, one at a time in the transverse direction Q protruding third protrusion unit 34 and a fourth protrusion unit 36 is available. The front face of the base plate 42 has a concave inner contour in some areas 38 whose radius of curvature corresponds to the radius of curvature of the outer contour of the vertical stem 58 corresponds. The clear interior distance IA between the third and fourth projection units 34 , 36 in the transverse direction Q corresponds essentially to the outer diameter of the vertical stem 58 (please refer 8th ). In the assembled state according to 8th lies the inside of the third and fourth projection units 34 , 36 on the outer contour of the vertical post 58 and the concave inner contour 38 lies on the outer contour of the vertical post in some areas 58 on.

The safety of one on the scaffolding 50 mounted railing device 10 against lifting in height direction H upwards this ensures that the first connection device in the assembled state 20th with their hooks directly below a protruding component of the existing scaffolding 50 , in the illustrated embodiment according to 11 of the gusset plate 64 of the scaffolding 50 is arranged so that a shift in the height direction H to the top of the in 11 Part of the right handrail post shown 16 is reliably prevented. At the same time, two railing devices grip in the assembled state 10 in adjacent scaffolding bays according to 11 the third and fourth protrusion units 34 , 36 the third connection device 24 under the first connection device 20th so that their displacement in the height direction H upwards and thus the shift of the in 11 left railing post shown on the right 18th blocked.

The railing device is thus in the connected state 10 against lifting in height direction H secured to the top. A shift in the width direction B. is also not possible, since this movement is caused by the positive engagement of the first connection device 20th and third connection device 24 on the vertical post 58 block a shift. At the same time, the first and third connection device 20th , 24 and the second and fourth connection means 22nd , 26th a displacement of the railing devices 10 in the transverse direction Q reliably prevented. The base plate of the second connection device 22nd and the third connection device 24 have a distance to the vertical stem in their front end area 58 on what threading these connector devices 20th , 24 during the assembly process for connection to the existing scaffolding 50 facilitated.

The 13 shows an example of a scaffolding bay on a lower scaffolding level in one perspective 52 a scaffolding 50 with two set up in the width direction B. spaced vertical frame 56 with each in the transverse direction Q spaced vertical stems 58 . The vertical stems 58 are in the upper end area via a crossbar 60 connected with each other.

In the lower end area connects the two vertical posts 58 of a vertical frame 56 a transverse profile 62 . In the corner area between crossbars 60 and vertical handle 58 is a stiffening gusset plate 64 arranged. At the same time, the vertical frame 56 Railing box 72 to the in 12 an existing handrail 70 is already connected.

In the 12 railing device shown 10 is currently in an intermediate assembly position. The right railing post 16 is raised to a height at which the second connection device 22nd in the crossbar 60 can be hung. Overall, the railing device is 10 in an inclined intermediate state, in which the first connecting device designed as a suspension claw 20th the vertical stem 58 not yet included and the second connection device 20th in the crossbar 60 is attached. During the further assembly process, the railing device 10 or the left railing post 18th raised upwards in such a way that the fourth connection device 26th of the left railing post 18th in the crossbar 60 can be hooked, in which case the first connection device is then simultaneously on the opposite side 20th the in 12 right vertical stem 58 partially includes a form-fitting and the third connection device 24 of the left railing post 18th with their base plate 42 on the outer contour of the in 12 left vertical stem 58 and the third and fourth protrusion units 34 , 36 the third connection device 24 with their inside on the outer contour of the vertical stem 58 issue. The final assembled state of the railing device 10 in a scaffolding bay is in 13 shown.

In 14th is a scaffolding 50 shown with a total of three scaffolding fields, each with a railing device 10 , as in 13 shown is mounted. This is above the lower scaffolding level 52 upper scaffolding floors still to be built 54 through the railing device 10 secured as the railing device 10 forms a side protection. In the next assembly step, decks can now be placed on the crossbars 60 the vertical frame 56 the lower scaffolding days 52 hooked and toe boards 68 to be assembled. Then the upper scaffolding days 54 can be entered by assembly personnel without risk, as the railing devices have already been installed 10 a safe side protection is guaranteed. Now, on the already erected vertical frames 56 the lower scaffolding days 52 further vertical frames 56 the upper scaffolding days 54 attached, as in 15th shown. In the last assembly step, the assembled railing device is now 10 from the lower scaffolding level 52 on the upper scaffolding level 54 implemented so that in the further assembly process also for the upper scaffolding days 54 A side protection is guaranteed for further scaffolding days to be assembled.

In on the scaffolding 50 The railing devices can be installed in the assembled state 10 neighboring scaffolding bays cannot be released. The dismantling takes place from an edge scaffolding bay on its vertical standard 58 the left handrail 18th connected.

When displayed in 15th corresponds to the connection situation of the railing devices 10 in the area of the two central vertical frames 56 the representation according to the 7th and 8th .

In addition, as in 2 shown - on the right handrail post 16 approximately at the height of the second handrail 14th one in the width direction B. outward-facing wrap-around profile 47 and on the opposite side by the left handrail post 18th slightly below the first handrail 12 one in width direction B. outward-facing wrap-around profile 47 present, which serves that the railing device 10 in the assembled state through these two encompassing profiles 47 are additionally secured again, for example by adding a railing box each 72 encompass.

In summary, the assembly of railing devices takes place 10 on the scaffolding 50 as follows. Based on the representation in 15th Without the railing devices already installed there, installation in the in 15th right scaffolding bay started. The right railing post 16 is via its second connection device 22nd and first connection device 20th on the right vertical post 58 or the crossbar 60 connected and then the left handrail post 18th via the third and fourth connection device 24 , 26th on the left vertical post 58 connected. The right handrail is in this condition 16 secured against lifting. In the next assembly step, the railing device 10 mounted in the middle scaffolding bays, again initially via the first and second connection device 20th , 22nd of the right railing post 16 on the right vertical post 58 of the middle scaffolding field, which is also the left vertical standard 58 of the first scaffolding bay. After the left railing post 18th with its third and fourth connection device 24 , 26th on the left vertical post 58 of the middle scaffolding bay is the right handrail post 16 the railing device 10 in the middle scaffolding bay and at the same time also the left handrail 18th the railing device 10 secured against lifting in the first scaffolding bay. The described The process is then continued successively in the respective neighboring scaffolding bays.

When dismantling a railing device 10 which, as already mentioned above, can only be made from the scaffolding field in which only the left handrail post 18th to an edge vertical stem 58 connected, such as the one in 15th left scaffolding bay, becomes the left handrail post 18th slightly raised to the hanging recess 44 with the crossbar 60 comes out of engagement. Then the left area of the railing device 10 be tilted slightly forwards or backwards and pivoted out and further downwards, so that the first connection device 20th with its hook-in claw out of engagement with the vertical handle 58 comes and then the second connection device 22nd by unhooking it from the crossbar 60 is resolved.
