EP0968341B1 - Dismountable scaffolding with base plates arranged on cross struts - Google Patents

Abstract

The invention relates to a dismountable scaffolding with vertical struts and horizontal struts. A base plate extends between said struts and is provided with hook-shaped end fittings on each front face. Said base plate can be placed on a rail section in such a way that vertical locking or unlocking can be selectably achieved by sliding the end fitting in the direction of the rail section. Horizontal antislip locking is achieved and cancelled by raising the end fitting, thereby preventing said fitting from sliding into an inactive vertical locking position when it is in an active vertical position.

Description

The invention relates to a dismantled scaffolding, in particular facade scaffolding according to the preamble of claim 1.

In a known scaffold of this type (DE 196 33 091 A1) are to the End fittings of the individual base plates provided latches when placing a base plate on the assigned rail profiles ensure that the end fittings snap into place so that the End fittings from the assigned rail profile only after pivoting the latch in a release position is possible. Such Training ensures that a base plate without one cross strut from above against its end fittings against lifting is securely held on the rail profile; the disadvantage, however, is that a movable element can be provided for this in the form of the latch which must be lifted by suitable measures by the operator is to be operated and during rough operation on a construction site damaged and thereby partially or completely rendered ineffective can.

Furthermore, it is already known (DE 39 23 815 A1 and EP 0 491 634 A1), above that interacting with the end fittings of the floor slabs Cross strut to arrange an additional cross strut, which is a safety catch represents for the end fittings or above a locking device representing recess in the cross strut lateral Protrusions that can be lifted off the end fittings by vertical as far from the one with the end fittings the bottom plates cooperating cross strut are removed that after lifting the end fittings a shift of the base plates such a piece is possible that the end fittings of the anti-lift protrusions be released and completely lifted off can. A disadvantage of these known arrangements is that above an additional cross strut is arranged on the end fittings of the base plates must be what is structurally and assembly-related complex and in addition leads to the lifting device preventing contamination and damage is exposed. If the top surfaces of the end fittings are not located significantly below the upper surfaces of the floor slabs between adjacent end fittings of two floor panels Stumbling threshold protruding beyond the level of the floor slabs.

The aim of the invention is therefore to provide a framework of the aforementioned To create genus in which the floor slabs without use movable elements on the rail profile and end fitting on the one hand without any problems applied to the rail profiles and removed from them can become, but on the other hand in the applied position an unwanted Take off, for example, by wind or wind attacking from below other lifting forces is avoided without the end fittings from above Cross struts of the scaffold must be secured.

This object is achieved with a scaffold according to claim 1. Further developments can be found in claims 2 to 7.

The idea of the invention can therefore be seen in the fact that only by a consequence suitable displacements of a floor slab in horizontal and vertical On the one hand, an easy application and removal of the Floor plates in relation to the assigned rail profiles is possible and on the other hand in the applied state the base plates against one Take off are secured by wind or other forces without that this requires additional cross struts above the rail profiles are. What is required to cancel the anti-move device The base plate is preferably lifted on one side, in particular in front.

The anti-lift device and / or the anti-shift device are preferred formed by stops according to claims 8, 9 and / or 10.

The insertion depth of each base plate is advantageously by the Measures of claims 11 or 12 limited, the insertion limit when using several base plates arranged one behind the other for the last base plate preferred by the vertical support and the floor slabs in front through the floor slab behind them is guaranteed.

The securing against lifting off is expediently according to claim 13 or 14 realized. It is a linear bayonet lock between the end fitting and the assigned rail profile.

A preferred practical embodiment for the anti-displacement stops one takes from the claims 15 to 17.

Also in the pull-out direction is at least for the foremost base plate a positioning stop according to Claim 18 provided so that when pulling out the base plate without special attention from the operator the position is found in which the anti-lift device is canceled. This stop is preferred according to claim 19 formed by the front vertical support.

This disengages the anti-displacement stops is possible while the anti-lift stops are still effective, the embodiment according to claim 20 intended.

If basically the various stops on the same side of the rail profile could be provided, it is preferred if these stops according to claim 21 are arranged, since then the anti-displacement stops conveniently between the rail profiles as preferably Sheet metal existing plates can be executed.

If basically a single base plate between provided two vertical supports and designed according to the invention can be, it is nevertheless advantageous, according to claim 22 preferably two or more of the same design To provide floor slabs one behind the other, because here in particular at high altitudes an easier manipulation because of the lower weight of the individual base plate is possible.

If several base plates are provided one behind the other, are the anti-slip stops on the rear floor panels expediently different from that of the front base plate formed according to claim 23.

So while the anti-displacement stops of the front Base plate are positioned so that their The front floor panel still comes into engagement is not possible are the stop plates located further back the rail profiles arranged so that when it comes into engagement with the positioning stops of the end fittings the anti-lift device has already been removed. This Education is possible and appropriate because, for as long the front base plate has not yet been removed, also the floor slabs further back through the same measures as the front base plate against shifting it can be lifted off to the insertion side position are secured.

A particularly advantageous further embodiment according to Claim 24 signals the operator when inserting of the floor panels particularly haunting whether they already are engaged or not yet. As long as the anti-displacement stops on the anti-slip stop plates between the rail profiles, the tilts Base plate when handling forwards and backwards, so that the Operator gets a feeling that the plate in question is not yet in its target position. First if the anti-shift stop of the final fitting from the stop plate at the back drops into the lowered position, the tipping stops and the user is signaled that the bottom plate is now in its final Target position. With several arranged in a row It is sufficient if only the foremost anti-slip stop plate is used trained accordingly is.

The embodiment according to claim 25 ensures that the floor slabs are also in the area next to the vertical supports, so that a there is a wider inspection area. Here it turns out Training according to the invention as particularly useful because by the training according to claim 25 a certain excess the floor slabs over the support surfaces on the rail profiles is present, upon entering a tilting moment on the Floor slabs are exercised around their longitudinal axis in the sense that they are trying to stand out from the rail profiles. This is however provided by the anti-lift device provided according to the invention effectively avoided, so that the excess of the floor slabs No interference at the front and rear via the rail profiles which represents safety in use.

The embodiment according to claim 26 ensures that with two adjacent floor slabs existing opening in the area of the end recesses downwards is secured by the positioning plate, which the The advantage is that falling through this opening Objects are stopped by the stop plate.

The embodiment according to claim 27 makes it possible to that the anti-lift device can also be folded down the base plate around one of the rail profiles can, causing the floor slab in question without moving in the direction of the rail profile, but by simple Down flaps can be lifted off. In reverse A base plate is also placed on top of that Rail profile possible. Folding down or up the base plates can be pushed apart by elastic allows two adjacent pairs of vertical supports become.

The embodiment according to claim 28 achieves that between the end fittings and the associated rail profiles a maximum contact area is provided.

Claim 29 characterizes a further advantageous training.

The training according to claim 30 or 31 facilitates putting on Bottom plate slanted from below onto a cross strut by the anti-slip stop with the rail profile to be dimensioned accordingly forms a lock that moves the end fitting over the cross strut and thus a fall of the relevant end the bottom plate prevented.

In the embodiment according to claim 32 there are both Sliding and lifting protection below the upper surface of the end fittings so that they protect against dirt and damage are protected. In this way, a stumbling block continues avoided even between adjacent end fittings, if the top surfaces of the end fittings and floor panels in vertical Are only slightly offset in the direction. This has a particularly favorable effect in the training according to claim 33.

1 is a facade scaffold on a building 37 under construction. On the ground 27 there are four vertical supports 11 in an arrangement with a rectangular base area, the longer side of which is parallel to the front of building 37 runs, supported by height-adjustable spindle assemblies 28 and by cross members 30 provided above headroom, Longitudinal supports 29 and diagonal struts 38 to form a stable one Base frame 41 completed, which is in Fig. 1st in the bottom right appropriately continues what is not in the individual is shown. The base frame 41 has in the lower Area, i.e. no cross struts below standing height, so that there is a passage e.g. intended for pedestrians can.

While the rear vertical supports 11 continue upwards, are the front vertical supports above the cross member 30 11 so backwards that the distance between front and rear vertical supports 11 more than is halved. The assembled from individual elements 11 ' existing vertical supports 11 arranged one behind the other form together with vertically spaced between them horizontal cross struts 12 end frames 32 which, as can be seen in Fig. 1 top left, asymmetrical be and can be plugged together. To this Numerous end frames 32 are possibly below Interposition of not connected with cross struts 12 Individual elements 11 'put one on top of the other so that in vertical Distance from planned floors A, B, C, D, E and F pro A vertical strut pair each has a cross strut 12 is. Along the building 37 are at regular intervals a total of seven end frame arrangements from vertical stacked faces 32 each with a number of transverse struts 12 at the same height intended.

On two cross struts arranged next to each other in front of the building 37 12 are each provided with end fittings 15 narrow sides of rectangular base plates 13 in the im individually described with reference to FIGS. 2 to 11 put on.

The facade scaffolding also has two protruding ones Auxiliary scaffolds 33 and 34 respectively.

The front vertical supports 11 at the corners of the base frame 41 can be used to attach other suitable above Support elements are used.

To secure the people working on the base plates 13 42 are on the vertical supports 11 at a suitable height Railings 39, 40 attached to the sides and on the end faces.

In particular on the side of the Floor plates 13 and, if necessary, also on the building 37 facing side and end faces are below preferably detachable on the cross struts 12 on-board strips 36 attached, which should prevent that on the floor plates 13 tools lying on the side when walking over the Base plates 13 are pushed out and from the facade scaffolding can fall down.

1, floors A, B, C, D have already been completed, while floors E, F are under construction.

2 to 4, the cross struts 12 consist of two at a distance from each other parallel to two in a row Individual elements 11 'of vertical supports 11 through Welding or a releasable type of attachment attached Rail profiles 14, 14 ', which are essentially C-shaped or vice versa have a C-shaped cross section and from a vertical strip part 14a or 14'a, a lower one horizontal short reinforcement flange 14b or 14'b and an upper horizontal flange 17, one has a greater width than the reinforcing flange 14b, 14'b. In principle, the two rail profiles 14, 14 'below by a dashed line in Fig. 3 elongated plate 43 to be connected to a structural unit.

The flanges 14b, 14'b and 17 of the two rail profiles 14, 14 'extend in opposite directions.

2, the rail profiles 14, 14 'at their ends welded at a distance K to a vertical support 11. The attachment could also be, for example, on the vertical supports 11 provided mounting rosettes can be detachable.

Between the vertical flat strip parts 14a, 14'a two rail profiles 14, 14 'extend according to Fig. 3.4 about halfway up in a horizontal distance a locking plate 18 and a positioning plate 18 ', which run essentially horizontally according to FIG. 4 or slightly from the insertion side 21 to the building side 22 can rise. The plates 18, 18 'are at both ends with the rail profiles 14, 14 'for example Welding firmly connected. Except for those below described functions of the plates 18, 18 'are on this way the existing from the rail profiles 14, 14 ' Cross struts 12 reinforced.

In the top and extending in opposite directions Horizontal flanges 17 of the rail profiles 14, 14 'recesses 20 are provided one behind the other, wherein there is a recess 20 each relatively close to the insertion side 21 and each have a further recess 20 near the Building 22 are located.

End fittings are on the narrow ends of the base plates 13 15, 15 'attached, which according to Fig. 3 essentially are hook-shaped and on the bottom plate 13 facing side a vertical with this firmly connected Strip part 15a or 15'a, a substantially horizontal running and essentially flat ceiling part 15b, 15'b and have an outer strip part 15c, 15'c, such that the end fittings 15, 15 'essentially one have an upright U-section.

To the superimposed components shown in Fig. 1 The rail profiles are easier to distinguish 14, 14 'with one from top left to right below and the end fittings 15, 15 'with a hatching from top right to bottom left.

According to the invention, at the lower edge of the strip parts 15a, 15'a horizontally in the direction of the associated rail profile 14, 14 'extending under the horizontal flanges 17 Lift-off protrusions 16 and between the rail profiles 14, 14 'lying strip parts 15c, 15'c below projecting anti-displacement stops 19 are provided, which with rear stop edges 23, 23 'of the anti-displacement stop plate 18 or the positioning plate 18 'work together.

The vertical distance G between the anti-lift protrusions 16 and the horizontal flange 17 in the attached According to the invention, the state of the base plates 13 is greater than the vertical degree of overlap between the plates 18, 18 ' and the anti-displacement stops 19.

The surface 24 of the stop plate 18 serves as a sliding surface for a lift lock stop raised on it 19th

The stop plate 18 and the stops 19 are horizontal Positioned towards each other in such a way that when struck of the projection 19 to the rear edge 23 of the stop plate 18 the anti-lift protrusion 16 of the end fittings 15, 15 'still below the horizontal flange 17 and definitely clearly behind the recess 20 is located, so that when lifting the end fittings 15, 15 'in this state, the projections 19 on the surface 24 raised, but the anti-lift protrusion 16 have not yet reached through the recess 20 upwards can. This is only possible if the protruding ones below Stops 19 so far on the surface 24 in the direction are moved to the insertion side 21 that the end fittings 15, 15 'in the area of front recesses 25 the front vertical support 12 come to a stop. The Length of the stop plate 18 and the anti-displacement stops 19 in the direction of insertion is such that the on Surface 24 of the stop plate 18 raised anti-slip stops 19 slide on the surface 24, until the associated end fitting 15 or 15 'when pulling out strikes forward on the front vertical support 11.

According to FIGS. 2 to 4, two identical designs are in succession Base plates 13 on a respective rail profile 14 or 14 'applied. The rear base plate 13 strikes provided in the area of one at the rear on the end fittings 15, 15 ' Recess 26 on the rear vertical support 11. In the middle, the two base plates 13 have at most a slight distance 31 or preferably meet to each other.

As can be seen particularly clearly from FIGS. 2 and 4, is the horizontal distance H of the anti-displacement protrusion 19 of the rear base plate 13 and the rear edge 23 ' the rear positioning plate 18 'significantly larger than the smallest possible distance 35 between the anti-displacement stop 19 of the front end fitting 15 and the Trailing edge 23 of the stop plate 18, which is only in the area of required tolerances.

In Fig. 2 there are also bores 44 in the end region of the Rail profiles 14, 14 'indicated that for inserting Retaining bolts, not shown, of the on-board strips 36 (FIG. 1) serve. In the area of the rear vertical supports 11 Holes 44 generally unnecessary because on the building side Bord strips 36 are not prescribed. According to the invention especially put those in the front holes 44 inserted, not shown, vertical bolt Bord strips 36 an additional safeguard against shifting the bottom plates 18 to the front. The holes 44 are so to attach accordingly.

In Fig. 4 left is further indicated, as on the individual elements 11 'provided plug 11 "telescopically into a subsequent single element 11 'are inserted, so one composed of numerous individual elements 11 ' To form vertical support 11.

Further features and details of the invention emerge from the following functional description under additional Reference to FIGS. 5 to 11.

2 to 4 are on the two rail profiles 14, 14 'in each case two end fittings 15, 15 or 15 ', 15' of two base plates 13 arranged one behind the other, in such a way that between the base plates 13 of the possible small distance 31 remains, which must be so small that no components or tools pass through it can fall down. The size of the distance 31 is through those required when building such a scaffold Tolerances determined.

The end fittings located on building side 22 strike 15, 15 'in the region of the recess 26 to the rear Vertical support 11, whereby the insertion depth of both Bottom plates 13 arranged one behind the other is determined. The displacement lock stop 19 on the insertion side 21 End fittings 15, 15 'located behind each reach behind the Trailing edge 23 of the locking plate 18, namely leaving the slight distance 35, which if possible should be small and with the usual tolerances such scaffolding is intended. This way are each both bottom plates 13 lying one behind the other secured against slipping to the insertion side 21.

Should now, for example, from below on the base plates 13 attacking wind forces try to pull them off the rail profiles 14, 14 'to take off, this is through the horizontal flanges 17 interlocking protrusions 16 prevented. The same applies if any tilting moments should occur around the longitudinal axis of the base plates 13, for example by stepping on the front or rear, above the support area on the rail profiles 14, 14 'projecting edge region of the base plates 13.

Should the base plates 13 of the rail profiles 14, 14 ' are lifted off, the on-board strips 36 are first removed the safety board retaining holes 44 removed. 5 and 7, one of the first front base plates 13 raised so far that the bottom protruding anti-displacement stop 19 to the level the surface 24 of the anti-displacement stop plate 18 raised, and then the bottom plate 13 in the direction of the arrow P moved to the insertion side 21, the stop 19 can slide on the surface 24. By the Raise the anti-displacement stop 19 to the level of the surface 24 becomes that by the anti-displacement stop plate 18 and the anti-lift stop 19 formed Anti-slip released.

The relevant base plate 13 is then so far in the direction of arrow P moved until the edge of the front recess 25 on the rear of the front vertical support 11 indicates the position in which the anti-lift protrusion 16 with the recess 20 in the horizontal flange 17 vertically is aligned with what the end fittings 15 or 15 ' easily upwards from the assigned rail profile 14 can be lifted off. To solve the front floor panels 13 is therefore a very conscious movement of the base plate 13 first required vertically upwards and then forwards, like they don't happen by wind forces can be caused, so that due to the invention On the one hand, measures to largely secure the given front floor panels 13 against accidental lifting is, on the other hand, a problem-free, conscious decrease is possible.

After one of the two front floor panels 13 according to 8 to 10 has been removed, can now no longer limited to the front by another base plate 13 rear base plate 13 also in the direction of Insert side 21 to be moved forward until the on their end fittings 15, 15 'provided anti-displacement stop 19 to the rear edge 23 'of the rear positioning plate 18 'strikes (Fig. 10). Now are - in Contrary to the situation with the front floor panels 13 - the anti-lift protrusions 16 and the recesses 20 vertically aligned with one another in the horizontal flanges 17, 9 so that the end fitting 15 of the associated Rail profile 14 can be lifted off. Both rear base plates 13 thus serve the anti-displacement stops 19 and the positioning plate 18 'only as an indicator by which when striking the two components 18 ', 19 are displayed to one another by the operator is that now the bottom plate 13 for lifting off the rail profile 14 is ready.

After the anti-displacement stop 19 above the level the surface 24 'of the positioning plate 18' has now been, the rear base plate 13 in Pull out in the direction of arrow R, whereby if necessary, the anti-displacement stop 19 on the Surface 24 'can slide.

The application of base plates to the rail profiles 14, 14 'proceeds in reverse order as follows:

First, the rear base plate 13 is from the insertion side 21 ago applied in such a way that the anti-displacement stop 19 on the rear positioning plate 18 'put on and the base plate 15 with the end fittings 15, 15 'is moved to the building side 22, whereby the anti-displacement stop 19 on the surface 24 ' the positioning plate 18 'slides back until it finally reaches behind the end edge 23 ', whereupon the end fitting 15 falls down until he is on his entire Length rests on the horizontal flange 17. Here moved the anti-lift protrusion 16 through the recess 20 below the level of the horizontal flange 17, whereupon the bottom plate 13 with the end fitting 15 in the 5 to 7 visible position moved to the rear until the end fitting 15 in the region of the recess 26 come to rest on the rear vertical support 11. Now the rear base plate 13 is in hers Target position.

To the sliding lock 19 on the positioning plate 18 'can facilitate this either designed as a ramp that rises to the rear be or on the insertion side 21 facing Such a ramp 18 "at the end. In this way can the anti-displacement stop 19 without the Bottom plate 13 must be raised when inserted, alone by pushing the bottom plate 13 backwards with the surface the ramp 18 "come into sliding engagement, so that the end fitting 15 when moving the base plate 13 to Building side 22 is raised until finally the Locking stop 19 behind the end edge 23 'of Positioning plate 18 'arrives and the end fitting 15 in in the manner described above, whereupon the Ceiling parts 15b, 15'b rest on the flange 17, like that e.g. can be seen in Fig. 3. Then follows again moving the end fittings 15, 15 'in the 2 to 7 apparent target position.

Now the front base plate 13 is also applied as follows:

The front base plate 13 is first so assigned to the Profile rail 14 placed that the end fitting 15 in Area of the front recesses 25 from behind to the Attach front vertical supports 11. In this position are the anti-lift protrusions 16 and the recesses 20 in the horizontal flanges 17 vertically with each other aligned so that the end fitting 15 so far after can move that the anti-shift stops 19 on the surface 24 of the anti-displacement stop plates 18 come into circulation. Because of the invention Dimensioning comes the anti-lift protrusions 16 now to lie lower than the horizontal flanges 17, so that when moving the bottom plate 13 in the direction the arrow S in FIG. 7, the anti-lift protrusions 16 reach under the horizontal flanges 17 before the on the surface 24 sliding safety stop 19 finally behind the rear edge 23 of the anti-displacement stop plate 18 arrives, whereupon the base plate 13 with the end fittings 15, 15 'down into their in the Fig. 2 to 4 shown target position falls where the ceiling parts 15b, 15'b of the end fittings 15 on the horizontal flanges 17th lie on continuously.

The displacement lock stops 19 are in the range of Middle of the end fittings 15, 15 'to be arranged so Resting the anti-displacement projections 19 on the Locking stop plates 18, 18 'the bottom plate 13 is in an unstable position in which to handle tilts about its longitudinal axis, which is for the operator This is indicated by the fact that the base plate 13 has not yet moved is in its end position. A stable, no more tipping position is only achieved when the anti-displacement stops 19 at the rear of the anti-slip plates 18 have slipped.

11, the rail profiles 14, 14 'and the End fittings 15, 15 'with their different projections and Recesses should be dimensioned so that everyone tilts Bottom plate 13 down from the secured against lifting Position is possible, in such a way that, for example when pivoting the base plate 13 around the rail profile 14 'down a lift in the direction of arrow T in Fig. 11 without prior horizontal displacement of the base plate 13 is possible. In reverse order can each base plate 13 in an inclined position also on the rail profiles 14, 14 'are placed, although on the on the opposite side first a dig in the top described meaning must take place. Once there the end of the Base plate 13 from its associated rail profile 14, 14 'is lifted, the front frames located there can 32 (FIG. 1) with the vertical supports 11 and cross struts 12 be resiliently pushed away from the base plate 13, whereupon the base plate 13 tilts downwards according to FIG Fig. 11 is possible. When placing a bottom plate 13 in 11 tilted state must then be the other End raised, with the end frame 32 pushed away in a springy manner raised above the level of the rail profile there and then on the rail profile as described above be put on.

So it is particularly advantageous that when tipping one Base plate 13 according to FIG. 11 none of the relative to each other moving parts come together so that they could be damaged or destroyed.

Because of the design according to the invention, any one front base plate 13 independent of the other base plates 13 disassembled and assembled. For removal one of the rear floor panels 13 need only initially the floor plates 13 in front of it are moved forward, the front one up to the front Vertical support 11.

In particular, the insertion of the bottom plates 13 is done by the training according to the invention made easier and safer, since the operator has a feel for both non-engaged as well as locked position of each base plate 13 gets.

After the security board retaining holes 44 according to the invention relatively close to the front and rear edges of the floor panels 13 or the end fittings 15, 15 'is a further indication of a correct positioning of the applied Bottom plates 13 to be seen in that the safety board retaining holes 44 for receiving the holding pin the on-board strip 36 is exposed. By inserting the Vertical pins of the on-board strips in the holes 44 are the base plates 13 in particular against shifting additionally secured at the front.

The anti-displacement stops 19 have the further advantage that if a bottom plate 13 with its underside placed obliquely (Fig. 11) on a rail profile 14, 14 ' and then lengthways to vertical of the upper end fitting 15, 15 'with the associated Rail profile 14, 14 'is shifted, at least according to below anti-displacement stop 19 behind that assigned rail profile 14, 14 'engages and so the longitudinal displacement is stopped at the moment when the final fitting 15, 15 'with the associated rail profile 14, 14' in the relative position required for a holding intervention located.
