Abstract

The invention relates to a railing element, in particular as a fall protection system for the construction of multi-floored buildings. A vertical section (46) is provided, comprising several horizontal sections (48) which are fixed thereto and are mutually vertically spaced, and the free end portions of which point in opposite directions with respect to the vertical profile (46).

Description

The invention relates to a railing element, in particular as a fall protection for the creation of multi-storey buildings.

In accordance with current regulations, fall protection must be provided when creating formwork for building ceilings. For this purpose it is e.g. customary to create a bottom-supported external scaffolding, which projects beyond a newly created building ceiling so far that the required fall protection can be installed before the installation of the necessary for the building ceiling formwork elements on the outer frame. Alternatively, vertical beams are each attached to a plurality of already completed building ceilings, which in turn protrude above the next, to be created building ceiling, so that there already a fall protection can be provided before the shuttering elements are mounted for the next building ceiling.

Furthermore, it is known from the prior art according to DE 10 2005 045 527 AI, to erect a protective wall on the outer sides of a building to be created, which is anchored to two superimposed, already created building ceilings by means of cantilevers and after building a building ceiling for Erection of another building ceiling can be raised by a drive to the corresponding floor level. At the upper end of this protective wall are fixed platforms secured by railings, which ensure access to the new building ceiling. However, the invention also relates to such railing elements, which are attached in any way to an outer frame, a building ceiling or any other support device, wherein it is not necessary that the above-mentioned vertical beams are provided, which up over a next building ceiling to be created protrude.

The attachment of railings to external scaffolds, protective walls, building ceilings or other support devices is often complex, since the dimensions of the building ceilings to be created are very different and it is therefore necessary vorzushalten railing elements in many different widths or special balancing railing elements, always a gapless To ensure security. Furthermore, an optimal adaptation of the railing to given dimensions, especially in the area of outside or inside corners, is often very difficult.

It is therefore the object of the invention to specify an easy-to-mount country element that can be universally used without adaptation work.

The object is achieved by the features of claim 1 and in particular by a railing element of the type mentioned above, which is characterized by a vertical profile with a plurality of vertically spaced apart horizontally spaced horizontal profiles whose free end portions facing in relation to the vertical profile in opposite directions. The railing element according to the invention is a fall protection, which is particularly easy to assemble, since it must be attached to only a single carrier. Several such railing elements can be mounted in such a way that a horizontal profile can extend with its free end between two horizontal profiles of an adjacent mounted railing element. This configuration makes it possible to freely choose the distance between two adjacently mounted railing elements at least within a certain range, without having to provide railing elements of different widths or to make adjustments to the railing elements or to gaps between adjacent railing elements. As it were, there is an entanglement of the horizontal profiles of adjacent railing elements, wherein all horizontal profiles can be located in the same vertical plane. An entanglement is also possible with an over-corner arrangement, in which case the horizontal profiles of adjacent railing elements intersect.

Preferably, two horizontal profiles of a railing element pointing in opposite directions are alternately offset relative to each other. This is also an entanglement or gearing of adjacent railing elements possible if they are each mounted at the same height to a respective carrier.

However, it can also be provided that in each case two horizontal profiles are arranged offset-free opposite each other or a continuous horizontal profile is fastened in its middle section to the vertical profile. In this case, the desired entanglement of the horizontal profiles of adjacent railing elements is then achieved in that the fastening positions of adjacent railing elements on a respective support in the vertical direction are slightly offset from one another, this offset may preferably be about half the vertical distance of the horizontal profiles from each other.

It is advantageous if the railing element comprises at least one coupling element which is provided for a releasable coupling of at least one free end region of a horizontal profile with at least one free end region of a horizontal profile of a further adjacently arranged railing element. As a result, the stability of the railing elements can be further increased, since the risk of bending is reduced when larger forces occur.

Preferably, the railing element can be fastened by means of securing bolts or by means of a clamping connection to a carrier. Preferably, the railing element on a contact surface for supporting a shuttering element. In this variant, the railing element at the same time the attachment of a formwork element that can be hooked, for example by means of hooks in the horizontal profiles. The contact surface ensures a stable position of the shuttering element in this case.

Further advantageous embodiments of the invention are specified in the subclaims, the drawings and the description of the figures. The invention will be described below with reference to the drawings. Show it:

Fig. 9 is a side view of the support device in an alternative mounting state. An inventive railing element is described in connection with a supporting device or a formwork system, which are particularly suitable for mounting the railing element according to the invention. An attachment according to the invention railing element on any other outer scaffolds, protective walls, building ceilings or other types of support devices is not excluded.

According to FIGS. 1 a to 1 e, a carrying device comprises a clamping device 12, which comprises two base bodies 14 which extend in the vertical direction and are spaced apart from one another, at the lower end sections of which a horizontally extending lower cantilever beam 16 is fastened. Of the two basic bodies 14 and lower cantilever beams 16 only one is visible in the side views of FIGS. 1a to 1c. As can be seen in particular in Fig. Ld, le and 3, the two are Base body 14 and lower Kragträger 16 via webs 38 connected to each other.

Between the base bodies 14 is a vertically adjustable (see double arrow in Fig. La) and pivotable about a horizontal axis (see double arrow in Fig. Lb) upper cantilever 18 is arranged. For this purpose, the base bodies 14 have a plurality of vertically spaced, horizontal bores 20 for receiving securing bolts 22 for fastening the upper cantilever beam 18 in the respective desired vertical position. Two different vertical positions are shown once in FIGS. 1a and 1b with solid lines and once with dashed lines. The securing bolt 22 can be passed through these holes 20 and also vertically spaced from each other, horizontal holes 20 of the upper Kragträgers 18.

If both securing bolts 22 are passed through the holes 20 in the upper cantilever beam 18, this is verschwenksicher fixed to the basic bodies 14 (Fig. La). In the adjustment position illustrated in FIG. 1b, the lower securing bolt 22 is pulled out of the bore 20 of the upper cantilever beam 18. After the upper cantilever beam 18 has been slightly pivoted upwards, which is indicated by the double arrow, the withdrawn lower securing bolt 22 has been inserted again into one of the bores 20 of the base body 14, so that it now has a stop for the upwardly pivoted upper cantilever. carrier 18 and keeps him in the pivoted position shown in FIG. Lb. The associated increase in the distance between the upper Kragträger 18 and the lower cantilevers 16 facilitates the installation of the clamping device 12 to an existing building ceiling. At the free end of the upper Kragträgers 18, a clamping device 24 is provided, which is shown in the embodiment as a spindle. In principle, however, other, preferably self-locking adjusting means can be used. The lower end portion of the clamping device 24 has a support 25 for the top of the building ceiling.

At the lower Kragträgern 16 opposite side of the base body 14 is a coupling sleeve 26 for receiving a vertical support 34 (see Fig. Lc) arranged. The coupling sleeve 26 is vertically adjustable by means of adjusting means, not shown, with respect to the base body 14 in height. The vertical support 34 as well as the coupling sleeve 26 is provided with holes 20a and 20b for securing bolt 22 for mutual locking. There is a certain play between the vertical support 34 and the coupling sleeve 26, so that the vertical support 34 can be pivoted by a small amount about the locking bolt 22 locked in the coupling sleeve 26. The coupling sleeve 26 has in the embodiment on a bottom, which, however, can also be omitted. For completeness, it should be mentioned that each of the holes 20, 20a, 20b may have a different diameter, especially if they are located on different components.

At the upper end region of the base body 14, a frame-shaped support element 28 is fastened, in which a guide sleeve 30 is slidably received horizontally in the main extension direction of the cantilever beams 16, 18. For horizontal adjustment of the guide sleeve 30 between the guide sleeve 30 and the bodies 14 effective spindle 32 is provided. Referring now to Fig. Lc, the various adjustment options that are provided in the clamping device 12, again explained. Within the circle A, a double arrow F is shown, which indicates the vertical adjustment of the tensioning device 24 and the upper Kragträgers 18.

First, a coarse adjustment of the distance between the cantilevers 16, 18 by selecting a suitable pair of holes 20 in the base body 14, in which the locking pins 22 are inserted.

To achieve the mounting position shown in Fig. Lc is the

Clamping device 12 is then first pushed onto the existing building ceiling 36 (FIG. 1c) with the cantilever beam 16 pivoted upwards (FIG. 1b) or "threaded". This relative movement between the building ceiling 36 and the clamping device 12 is indicated in Fig. Lc with the arrow in the mark B.

Subsequently, the upper cantilever beam 18 is pivoted downwards into the working position according to FIG. 1 c and fixed with a second (lower) securing bolt 22.

Then, the clamping device 24 is actuated, so that the support 25 moves in the direction of the arrow F down and the building ceiling 36 is clamped between the lower cantilever beams 16 and the support 25. The defined by the two lower Kragträger 16, sufficiently dimensioned surface ensures a reliable fixation of the clamping device 12 on the underside of the building ceiling 36 so that tilting of the clamping device 12 is excluded about a horizontal axis. The double arrow bounded by the mark C symbolizes the subsequently possible vertical adjustment of the vertical support 34 via a corresponding vertical displacement of the coupling sleeve 26 by means of a spindle (not shown). Finally, the double arrow bounded by the mark D indicates the further possible tilt adjustment of the vertical support 34 with respect to the base body 14 fixed to the building ceiling 36 by means of the spindle 32. The importance of this adjustment of the vertical support 34 will be explained below.

Fig. Ld and le show an arrangement of two clamping devices 12, 12 ', which are formed largely in the manner described above, for an over-corner attachment to an outer corner of the building ceiling 36, in which due to space constraints or static reasons the lower cantilever beams 16, 16 'must overlap. Fig. Ld shows the mounted on the building ceiling 36 arrangement obliquely viewed from below with a view towards the underside of the building ceiling 36, while in Fig le the arrangement without the building ceiling is seen obliquely from above.

For this purpose, the lower Kragträger 16 'of a clamping device 12' on its upper side with two spacers 39 are provided. The spacers 39 have a T-shaped configuration, wherein the transverse bar of a T performing portion rests on the two cantilevers 16 'and a foot of a T performing section between the cantilever 16' protrudes and to the cantilever 16 'connecting webs 38th is fastened for example by means of screwing.

The transverse bar of a T performing section is at least as strong as the cantilever 16 of the other clamping device 12, so that the Support base of the cantilever beam 16 'on the underside of the building ceiling 36 in an outer corner mounting according to FIG. Ld compared to an exclusive edition of the cantilever beams 16 in a mounting without spacers is increased accordingly and the spanned by the two spacers 39 pieces Area corresponds.

Referring now to FIGS. 2 to 7, the structure of a formwork system according to the invention will be explained in more detail. On an existing building ceiling 36 on which pillars 40 have already been erected as a support for a new building ceiling to be created, a plurality of clamping devices 12, vertical support 34 and even closer to described railing elements 42 and formwork elements 44 are provided (Fig. 2). In each case a clamping device 12 and a vertical support 34 are joined together to form a carrier device 10 (FIG. 3).

As can be clearly seen in FIG. 3, a railing element 42 according to the invention is attached to an upper end region of the vertical support 34. In order to enable at least a large-scale adaptation to the desired floor height of the new building ceiling to be created, both the upper end region of the vertical support 34 and a vertical profile 46 of the railing element 42 are provided with a plurality of bores 20 spaced from each other vertically. The fastening takes place by means of securing bolts which are not recognizable here and which are inserted through the bores 20 of the two parts 34, 46 to be connected.

A plurality of vertically spaced horizontal profiles 48 are attached with its one end portion to the vertical profile 46. The other end area is free. The horizontal profiles 48 extend alternately in opposite directions, ie between two horizontal profiles 48, which point in one direction, there is a horizontal profile 48, which faces in the opposite direction, so that the horizontal profiles 48 are arranged on both sides of the vertical profile 46 offset from each other.

At the preassembled supporting device 10, in the region above its center of gravity, a carrying cable or carrying chain 50 of a lifting device is fastened in order to transport the carrying device 10 into a mounting position according to FIG. 4 (see upper carrying device 10). For attachment of the support chain 50 to the vertical support 34 is provided with an eyelet for suspending the support chain 50 fastener 51 is provided, which by means of a safety pin 22, in a above the

Center of gravity of the support device 10 in the vertical support 34 introduced further bore 20a is added, is set to the vertical support 34 (Fig. 3). The support device 10 is clamped in the manner described above to the existing building ceiling 36.

These steps are repeated until the building ceiling 36 is provided along its respective desired peripheral area with supporting devices 10 (Figure 5). It is possible to use two or more supporting devices 10, e.g. by means of diagonal struts (not shown) to couple into a unit and to mount these coupled support devices 10 together

and / or convert from one building ceiling to the next, which reduces the time required for assembly or implementation.

In Fig. 5 can be clearly seen that the railing elements 42 already form a complete fall protection for work on a still to be created slab formwork. In particular, it is easy to see how the horizontal profiles 48 of a railing element 42 extend between the horizontal profiles 48 of an adjacent railing element 42, without it requires an adjustment of the railing elements 42 as a function of the distance between adjacent support devices 10. As a result, it is also not necessary to pay attention to a precise adherence to a predetermined grid temperature when fastening the carrying devices 10 to the building ceiling 36. Only a predetermined by the width of the railing elements 42 maximum distance is taken into account.

Alternatively, railing elements 42 'according to the invention according to FIG. 8 can also be used instead of the railing elements 42, in which, in contrast to the railing element 42 (FIGS. 2 to 7), two horizontal profiles 48 pointing in opposite directions are arranged without offset on the vertical profile 46. Optionally, instead of two individual horizontal profiles 48, a continuous horizontal profile may be provided.

When using railing elements 42 'without offset of the horizontal profiles 48, the desired entanglement of the horizontal profiles 48 adjacent railing elements is achieved by the attachment positions of adjacent railing elements at their respective vertical supports 34 in the vertical direction are slightly offset from each other, said offset preferably about the Half of the vertical distance of the horizontal profiles 48 may be from each other.

Especially when looking at the outer and inner corner regions (FIG. 5), it becomes clear that building ceilings 36 of arbitrary dimensions can be created and secured with both railing element variants without the need for specially adapted railing elements 42, since the horizontal profiles 48 of adjacent railing elements 42 both when arranged on a longitudinal side of a building ceiling 36 as well as in shown in Fig. 5 outer corner (see arrows A) and inside corner Arrange arrangements (see arrow B) at an angle over a wide distance range without any problems.

To increase the stability of the protective railing, additional coupling means can be provided between individual horizontal profiles 48 of adjacent railing elements 42. However, this is due to the torsional stiffness of the vertical beam 34 and the flexural rigidity of the Horizontalpro file 48 is not mandatory. After mounting the support devices 10 together with the railing elements 42 formwork elements 44 can now be suspended in the railing elements 42.

In the exemplary embodiment illustrated in FIG. 5, a shuttering element 44 in each case comprises three formwork panels 54 which are rigidly coupled to one another by means of a plurality of continuous coupling profiles 56 arranged on the rear side of the formwork panels 54. In principle, the use of formwork elements with a different number of formwork panels 54 is possible. For example, a formwork element with only one formwork panel 54 can also be used.

Also on the rear side of each formwork panel 54 are hooks 52a, 52b, which have a vertical offset relative to one another which corresponds to the offset of the horizontal profiles 48 fastened on opposite sides of the vertical profile 46.

So that the guardrail has a sufficient effective height, the formwork elements 44 are preferably suspended in the respective lowest horizontal profiles 48. One provided on the vertical profile 46 A contact surface 60 ensures reliable vertical alignment of the formwork elements 44 (see also FIGS. 3 and 8).

After all formwork elements 44 have been suspended in the corresponding railing elements 42, according to FIGS. 6 and 7, a supporting structure 62 for a slab formwork can be erected. Formwork floor elements 64 can now be attached to this support structure 62. In order to ensure support of the shuttering floor elements 64 also in the edge area, the shuttering panels 54 are provided on their front side with a support 58 for the shuttering floor elements 64.

From Fig. 6 it can be seen that by means of the vertical and tilt adjustment of the vertical support 34, an exact and fine-level adjustment or leveling of the formwork elements 44 in relation to the height and the lateral dimensions of the new building ceiling to be created is possible.

Finally, the formwork created in this way can be filled with concrete 66 (FIG. 7), which forms the new building ceiling to be created after hardening. In order to avoid that individual shuttering elements 44 are pressed outwardly by the load of the concrete 66, the inclination adjustment of the vertical support 34 allows an additional pretension to be exerted on the shuttering elements 44 so that the predetermined dimensions for the new building ceiling to be created can be maintained.

If higher loads are to be intercepted during concreting, all or part of the supporting devices 10 on the existing building ceiling 36 in addition to the attachment by means of the clamping device 12 can also be braced, as shown in Fig. 9. To this Purpose, the support cable or the support chain 50 may be used, which was already hooked for the previous transport with its one end in the fixed to the vertical support 34 fastener 51. The vertical support 34 is provided with a plurality of vertically spaced holes 20 a, which optionally allow a selection of another fastening position for the fastening element 51 (see also Fig. 3). In general, however, no re-assembly of the fastener 51. The other end of the support chain 50 is suspended in an adjustable clamping element 68, which in turn is mounted in a fastened to the building ceiling 36 coupling element 70. By pressing the clamping element 68, a tensile force is exerted on the vertical support 34 via the support chain 50 and the support device 10 is biased accordingly.

With the railing element according to the invention, it is thus possible to build a fall protection for work on a formwork for a newly created building ceiling or for the concreting of the building ceiling in a simple manner.
