DESCRIPTION OF THE INVENTION

Based on the above-mentioned prior art, the present invention is based on the technical problem or task of providing a solution for a corner area of a scaffolding arrangement which ensures simple assembly or disassembly, has a high load-bearing capacity and, moreover, enables stepless height adjustment in a simple manner.

The invention is further based on the task or technical problem of specifying a console device which can be easily manufactured, can be easily assembled or disassembled, ensures high load-bearing capacities and is continuously height-adjustable in conjunction with another console device.

The corner region of a scaffolding arrangement with bracket devices according to the invention is given by the combination of the features of independent claim 1. Advantageous embodiments and further developments are the subject of the dependent claims.

The corner area of a scaffolding arrangement with bracket devices according to the invention is formed by the combination of the following two bracket devices connected to a single vertical post/corner post of a scaffolding arrangement: - a first bracket device known per se with a cantilever bar, a vertical bar and a diagonal bar, whereby the bars form a triangular structure, a pipe coupling for connection to the vertical post is present in the upper area of the vertical bar and the diagonal bar is supported with its lower end on the vertical post and

- a second console device arranged substantially at right angles to the first console device with a cantilever bar, a vertical bar and/or a diagonal bar, wherein the bars form a triangular structure, the diagonal bar is supported with a lower end on the vertical post and a connection unit is present in the upper region of the vertical bar and at the end of the cantilever bar for connecting the second console device to the pipe coupling of the first console device, such that when the console devices are connected, the cantilever bars are at the same height.

This creates a corner area where both brackets are at the same level and a panel can be easily hung. The connection is made on a single post, so it is not necessary to set up a second post. The second bracket can be easily installed when the continuous corner post is already installed or at a later date.

The inventive design of the bracket devices makes it easy to adjust the height in the corner area. Because the second bracket device is only attached to the pipe coupling of the first bracket device, the entire corner area can be adjusted in height along the corner post by partially loosening the pipe coupling of the first bracket device. This design therefore enables stepless height adjustment, so that the bracket position can be moved to the optimal height for the working craftsman, which is particularly advantageous when doing latching work, for example.

The first console device is a series console that can be manufactured economically and easily installed. The second console device has the connection unit and can be easily mounted or dismantled on the first console device or on the corner post by simply hanging or unhooking the connection unit in/from the area between the corner post and the first console device above the pipe coupling.

A particularly advantageous embodiment is characterized in that the connection unit is designed as a hook unit that engages over the pipe coupling of the first console device. The hook element preferably has an L-shaped outer contour with an end leg pointing downwards.

A particularly advantageous embodiment is characterized in that a walkable plate secured against lifting is suspended in the cantilever bars of the bracket devices, which are designed in particular as U-profiles that are open at the top.

In order to be able to guarantee high load-bearing capacities, an advantageous embodiment is characterized in that the plate has at least one stiffening support on the underside, wherein the stiffening support is preferably arranged on the two free cantilevered plate edges on the underside of the plate.

WAYS TO CARRY OUT THE INVENTION

Fig. 1 shows a schematic plan view of the connection situation in the corner area E of a structure 66, for example a tank. Two scaffolding arrangements G meet one another perpendicularly. Cantilevered bracket areas K are present on the scaffolding arrangements G, projecting towards the structure 66.

In the corner area E, two bracket devices 10, 44 meet vertically at the common corner post 60. The use of two identical series bracket devices is not possible because there is not enough space available for the connection of two series brackets, since the series bracket has a pipe coupling at a predetermined position for connection to the corner post and a second bracket cannot be connected in this occupied connection area.

According to Fig. 3, a known bracket device 44.1 is connected to the corner post 60 in the corner area E as a series component. The first bracket device 44.1 has a cantilever bar 52 arranged on the top in the form of a U-profile that is open at the top, a vertical bar 54 and a diagonal bar 56. The bars together form a triangular support element. Just below the cantilever bar 52, a pipe coupling 42, which is designed as a pipe half-coupling, is welded to the vertical bar 54. By means of this connection, the tensile force that occurs when loaded as a result of the cantilever effect is transferred to the corner post 60. The diagonal bar 56 is supported in its lower end area by pressure against the corner post.

25

At right angles to the first console device 44.1, a second console device 10.1 is present in Fig. 3, which also has a cantilever bar 20 on the top that is designed as an upwardly open U-profile and has a diagonal bar 24 and a vertical bar 22. In principle, the structure is similar to that of the first console device 44.1.

A connection unit 18 designed as a hook element is welded into the connection area of the cantilever rod 20 or in the upper area of the vertical rod 22. The design of the connection unit 18 is shown in more detail in Fig. 4. The connection unit 18 is designed as an L-shaped hook element with an inner leg pointing downwards. The connection unit 18 is designed as a narrow rectangular cross-section so that it is guided between the vertical rod 54, the first bracket device 44.1 and the corner post 60 and overlaps the pipe coupling 42 of the first bracket device 44.1. This makes it possible to transfer the tensile force occurring when the first bracket device 10.1 is loaded via the connection unit 18 to the pipe coupling 42 and to pass it on to the vertical post 60.

The diagonal bar 24 is supported at its lower end on the corner post 60 via a U-shaped support shoe 70. A locking or fixing can be achieved by screwing in a recess 36 of the support shoe 70.

The covering surface in the corner bracket area E is made possible by the plate 58 shown in a schematic perspective in Fig. 2. This is a square plate which has a side length that is slightly smaller than the length of the cantilever bars 20, 52, and which has corresponding hooking claws 13 on the side edges facing the bracket devices 44.1 or 10.1 for hooking into the cantilever bars 20 or 52. At the same time, a downward bevel 68 of the plate 58 is present on these side edges. The plate 58 has a lifting and tilting protection unit 30 in the right-hand hooking edge in Fig. 5 approximately in its middle area.

which is formed as an outward-facing edge running parallel to the surface of the panel onto the lower edge of the edge 68. Fig. 6 shows a schematic cross-section of the suspended side edge with the lifting and tilting protection unit 30. To suspend the panel 58, it is placed at an angle of approximately 45° to the cantilever rod 20. After the suspension claws 13 engage in the interior of the U-shaped cantilever rod 20, the panel 58 is pivoted into its horizontal end position, in which state the lifting and tilting protection unit 30 grips under the cantilever rod 20.

The lifting and tilt protection unit 30 can also be present only in the left hanging edge of the plate 58 in Fig. 2.

The plate 58 can be made of checkered sheet metal, for example. A stiffening beam 62 is welded to the underside of the plate 58, extending diagonally from the corner post 60 to the free projecting corner area of the plate 58. Alternatively, a further stiffening beam 62.1 can be welded to the free edge area of the plate 58.

In the bracket devices 10.1, 44.1 shown in Fig. 3 and 4, the length of the cantilever bar 20 or 52 is selected such that a decking element 12 can be suspended via suspension claws 13. In the front free corner area of the cantilever bar 20 or 52 there is an upwardly pointing connection unit 28, which in the embodiment is designed as a pin to which further scaffolding elements can be connected.

The corner area shown in a detailed perspective in Fig. 5 shows a first bracket device 44.2 and a second bracket device 10.2, which are connected to the corner post 60 at right angles to one another, whereby these bracket devices 44.2, 10.2 differ from the bracket devices 44.1, 10.1 only in that the cantilever rod 52 or 20 is long enough that two scaffolding planks 12 can be suspended. Otherwise, the basic structure is the same. Identical components have the same reference number and are not explained again. Furthermore, the plate 58 is shown in the unhooked state in Fig. 5.

By partially loosening the pipe coupling 42, the entire corner area with the two bracket devices 10.1, 10.2; 44.1, 44.2 with the plate 58 can be continuously adjusted in height.

When connected to the single corner post 60, both bracket devices 10.1, 10.2; 44.1, 44.2 are automatically at the same height level H. The second bracket device 10., 10.2 can be easily installed later.
