Definitions
- the invention relates to a dismountable scaffold with walk-on coverings arranged in several levels and a plurality of vertical supports that support them, preferably consisting of a plurality of sections that can be plugged onto one another, are arranged at a distance from one another and are connected at predetermined vertical distances, preferably by means of covering bolts, at predetermined vertical distances Wear perforated rosettes, these connecting railing elements can be attached to adjacent vertical supports.
- Such a framework is known from DE 101 11 976 A.
- the rosettes of the vertical supports one above the other are generally at a distance of 50 cm from one another.
- railing elements are hung on the outside of the scaffolding, by means of which the persons walking on the floor covering are secured against falling.
- a railing element can expediently also be attached to the perforated rosettes located immediately above the covering bars, so that each level of the scaffolding is ultimately secured by two railing elements arranged one above the other.
- the only or uppermost railing element above a covering is preferably attached by the method as described in DE 196 33 092 AI is described.
- the railing element is therefore already installed before the assigned floor covering is installed. In this way it is ensured that a person entering the floor covering is in any case secured from the start by the railing element.
- top railing element above a floor covering often has a predetermined distance of e.g. Must have 1 m from the latter, which is greater than the distance of a perforated rosette assigned to the railing element from the covering.
- the object of the invention is to develop a scaffold of the type mentioned at the outset in such a way that the only or at least the uppermost railing element above a covering can be attached to the associated vertical support at a distance above the associated floor covering, which is not restricted by the specified one The distance between the rosettes is limited.
- This object is achieved according to the invention in that for the attachment of one or more railing elements above a covering, at least the top railing element of a floor can be attached to the associated perforated rosette via a railing adapter which, in its state attached to the perforated rosette, carries a railing holding element above the perforated rosette , whose distance to the rosette is smaller than the distance between two vertically adjacent rosettes.
- a railing adapter creates the possibility of attaching a railing element to the rosette at a desired distance above it.
- the scaffold is designed according to claim 2, whereby the
- the assembly of the railing adapter is significantly simplified by the design according to claim 1 1 compared to a screw mechanism.
- a hook-wedge mechanism ensures that the railing adapter can be attached to a perforated rosette in a simple, secure and solid, but nevertheless detachable manner. In this way, the railing adapter only needs to be placed on the rosette from above and inserted into one of the holes in it, the wedge fixing the railing adapter automatically falling into the assigned hole of the rosette and thus fixing the railing adapter.
- the railing holding element is preferably designed according to claim 13. This has the advantage that the railing element can be attached by means of the method according to DE 196 33 092 AI. This preferred embodiment of the invention thus also enables the attachment of railing elements which are not suitable at all for a direct connection to a perforated rosette.
- the railing adapter according to the invention thus not only ensures the attachment of railing elements at a desired distance above the associated rosette, but also gives the possibility of using any railing holding elements which are adapted to the fastening requirements of a desired railing element.
- the railing adapter according to the invention thus fulfills a double function by using any one Railing elements allowed and a desired distance of these railing elements above the assigned rosette ensures.
- the embodiment according to claim 16 ensures that the railing holding element does not protrude or does not protrude too far beyond the outer circumference of the perforated rosette.
- the development according to claim 17 serves to save weight and easy handling.
- a particularly compact and stable embodiment is defined by claim 18.
- the housing which is designed as a solid base body, is supported both vertically on the rosette and horizontally on the circumference of the vertical supports.
- the hook-wedge mechanism mentioned above causes the wedging provided for a tight fit.
- the railing adapter is additionally supported on the vertical support at the level of the attachment of the railing holding element.
- the invention further relates to a railing adapter according to claim 20, as can be used with advantage for the dismantled scaffold defined in the preceding claims.
- FIG. 1 shows a perspective view of a dismantled facade scaffold corresponding to the prior art, in which the invention can be applied,
- FIG. 2 shows a perspective partial exploded view on an enlarged scale to illustrate certain individual parts of the scaffold according to FIG. 1,
- FIG. 3 shows an enlarged perspective view of a vertical support section with a perforated rosette and railing adapter according to the invention attached to it from obliquely above,
- FIG. 4 shows a perspective view of a vertical support section with two perforated rosettes arranged one above the other, to each of which a railing adapter according to the invention is attached,
- FIG. 5 shows a perspective partial view similar to FIG. 3, but with the wedge mechanism of the railing adapter being shown cut open and a railing element being indicated by dashed lines
- FIG. 6 shows a side view of the object of FIG. 5 in the direction of the railing element with a partial section
- FIG. 7 shows a perspective view of a railing adapter according to the invention obliquely from the front
- FIG. 8 shows a rear view of the railing adapter according to the invention
- Figure 9 is a side view of the railing adapter according to the invention.
- Figure 10 is a plan view of the railing adapter according to the invention.
- a dismountable scaffold has vertical supports 12, 13 consisting of, for example, 2 m or 3 m long individual sections 12 ', 13', which are arranged at predetermined, preferably equal, vertical distances of e.g. Wear rosettes 14 extending around them around 0.5 m.
- topping bar 15 are suspended in assigned rosettes 14.
- the topping bars 15 are used to hang in elongated, rectangular toppings 11 that can be walked on by people.
- the ends of rod-shaped railing elements 16, 17 are fastened to the perforated rosettes 14 of adjacent vertical supports 12 on the front of the scaffolding, which ends are attached to the coverings 11 to secure working people against falling. While two railing elements 16, 17 lying one above the other offer a higher degree of security, a single railing element 16 above each covering 11 would in principle also be sufficient to secure the people working on the covering 11.
- a covering 11 is attached to the perforated rosettes 14 one above the other via the covering bolts 15, then a first railing element 17 and a second railing element 16.
- the perforated rosette 14 above has no function.
- the scaffold has diagonal supports 20 on the front at certain points, which can extend from one of the perforated rosettes 14 of the vertical supports 12 to perforated rosettes 14 of an adjacent vertical support 12 arranged further down or up.
- the lowermost vertical support sections 12 ', 13' are designed to be substantially shorter than the sections above them; they represent the base of the scaffold and are connected by covering bars 15, which, however, do not have to have a covering.
- Height-adjustable spindles 52 are provided between the lowermost rosettes 14 and the base plates 51, which serve to support the floor, in order to compensate for uneven floors, which are not shown in FIG. 1 for the sake of clarity.
- horizontal bars 18 are fastened above the base plates 51 or spindles 52 between the perforated rosettes 14 of adjacent vertical supports 12, 13 according to FIG.
- the facade scaffold shown in FIG. 1, for example, has a non-accessible substructure F and, above it, three floors A, B and C that can be walked on due to the coverings 11. Levels A, B and C are closed on the right-hand side by end railings 19.
- the second front vertical support section 12 'seen from below is longer by two perforated rosettes 14 than the second rear vertical support section 13', while the other vertical support sections 12 ', 13' located above are all of the same length are formed and each carry four rosettes 14.
- This design is important for the attachment of the railing elements 16, 17 according to the invention, because it makes it possible to bring a front vertical support 12 'from an already created covering 11 by plugging it onto the already completed part of the vertical support 12, that a railing element 16 can be hooked onto a railing adapter 21 provided on the uppermost perforated rosette 14 according to FIGS. 3 to 6.
- the rear vertical support sections 13 ' can each end immediately above a covering bar 15, while the front vertical support sections 12' stand up by two rosettes each extend over each topping bar 15.
- the perforated rosettes 14 have four relatively large ones at an angular distance of 90 ° relative to the vertical support axis 27 profiled holes 23 and relatively small circular holes 28 therebetween.
- the large holes 23 serve to fasten the covering bolts 15 and the railing elements 16, 17 by means of a railing adapter 21 according to the invention, while the small holes 28 e.g. can be used for holding the ends of the diagonal supports 20.
- FIGS. 5 and 6 which consists of a flat profile 25 which runs obliquely from bottom to top towards the vertical support 12, a hook wedge mechanism 26 arranged thereon with a housing 37 designed as a solid base body and there is a railing holding element 22, which extends essentially vertically inwards and away from the flat profile 25, to which, according to DE 196 33 092 A1, a railing element 16 having a hanging opening 30 at each end is attached, as shown in dashed lines in FIGS. 5 and 6 is indicated.
- the flat profile 25 has at the top a bend 29 directed towards the vertical support 12, which on the side facing the vertical support 12 has a support surface 24 corresponding to the outer contour of the vertical support 12, which abuts the circumference of the vertical support 12 in the assembled state.
- the flat profile 25 with one facing inwards Provide support bend 31, which rests on the top of the perforated rosette 14 in the assembled state.
- the wedge mechanism 26 consists of a wedge hook 32 suspended in the associated hole 23 and a wedge 34 which can be displaced in a groove 33 of the same and which are designed and function in accordance with EP 0 876 541 B1.
- an inward-pointing projection 35 Provided on the wedge 34 is an inward-pointing projection 35, which prevents the wedge 34 from falling out when the railing adapter 35 is not assembled and, when the railing adapter 21 is mounted, enables the wedge 34 to be subsequently fixed.
- the wedge 34 can ultimately be driven so far that it rests on the upper side of the support bend 31.
- the housing 37 of the hook wedge mechanism 26 is supported on both sides by means of support projections 36 on top of the perforated rosette 14 and at the rear by means of upper and lower support surfaces 39 on the vertical support 12.
- the function of the railing adapter 21 according to the invention is as follows:
- the railing adapter 21 is placed at the desired location from above on the rosette 14, the wedge hook 32 penetrating into the opening 23, but the wedge 34 is supported with its lower end on the top of the rosette 14 outside the hole 23 and thereby in the Groove 33 is displaced upwards relative to the wedge hook 32.
- the railing adapter 21 according to the invention is thus first attached to the perforated rosette 14 and the associated vertical support 12 (or 13) and thus becomes an integral part of the vertical support. Only then is the railing element 16 attached to the railing holding element 22, as in the case of a vertical support equipped directly with the railing holding element 22. The railing adapter 21 according to the invention is accordingly fastened to the perforated rosette 14 independently of the railing element 16.
