Abstract

The system for attaching a climbing bracket (1) to an anchoring device (23) embedded in a sub-structure comprises the climbing bracket (1) on which a hook (11) is slidably guided in the upper leg (3) and in which a hook (11 ) attached securing element (19) after the insertion of the hook (11) through the insertion channel (26) extends out of the cross-sectional area of the hook (11) upwards or to the side and thereby prevents the retraction of the hook (11) through the insertion channel (26).

Description

The subject matter of the invention is a method for automatically activatable, safe connection of a climbing bracket to an anchoring device according to the preamble of claim 1.
The invention also relates to a system for fastening a climbing bracket to an anchoring device according to the preamble of claim 4.
The invention also relates to a climbing bracket according to the preamble of claim 7.

Climbing brackets of the type mentioned are used to be able to attach slab edge formwork with little effort and to be able to carry wall formwork, in particular large-area wall formwork panels, and / or at the same time to be able to create scaffolding along the crowns of walls, in particular partial structures. The climbing brackets have the shape of a right triangle, one leg of which forms the upper and load-bearing crossbeam, the second leg comes into contact with the wall or the sub-structure and the hypotenuse or base of the triangle is designed as a load-bearing strut. On the traverse, a hook is formed in the area of the connection of the two legs and as an extension of the traverse, the end of which into a Recess in the wall forming anchoring device engages. Such anchoring devices are attached to the formwork before the sub-structure (wall) is poured by attaching a mounting pin to the formwork with a nail and then pushing the opening on the anchoring device onto the mounting pin. After the construction of the sub-structure, the mounting pin, which is located in the surface of the wall, can be removed, thus exposing the opening of the anchoring device. The anchoring device extends behind the opening into the wall and, at a distance from the opening, over a further area downwards, so that the hook on the climbing bracket is guided downwards through the opening and at the lower edge of the can and at one there existing wall section can be hung. A climbing bracket anchoring device system constructed in this way can probably accommodate the necessary load-bearing capacity for the climbing bracket. However, the climbing bracket is only held by gravity and if a crane load accidentally hangs on the climbing bracket from below and lifts it, the climbing bracket is not secured and can become detached from the wall.
In a further development of such a known climbing console anchoring device system, a reinforcing iron is inserted in the box below its opening and the hook on the climbing console is cranked so that the cranked section engages under the reinforcing iron, but only if the hook was previously manually wedged withdrawn and the climbing bracket has been pulled up against the wall, making it more difficult to lift the climbing bracket, but not sufficiently secured. In a further embodiment of the known climbing bracket, the hook is in the traverse displaceable and after the hook has been suspended in the anchoring device, the climbing bracket can in turn be additionally secured by means of a wedge which penetrates the crossbeam and pulls the hook back. Such a climbing bracket, if it has been attached correctly, is kept relatively safe, but the construction worker who attaches the climbing bracket has to move over it and pass the wedge through the crossbeam and the hook unsecured outside the wall and also below its crown and hit.

In the EP 3 032 002 a climbing bracket and a cladding part for one is described, which climbing bracket comprises a frame and in this a sliding hook, which can be hung in the cladding part forming a wall recess and can be secured within the cladding part against detachment from the cladding part, with the cladding part and for securing the hook must each include at least one passive safety element. Such a securing part can be a securing flap which is pivotably hinged in the casing part and, after the hook has been inserted and lowered, comes to rest between the upper surface of the casing part and the upper edge of the hook, thus preventing the hook from being lifted.
In a further embodiment of this prior art, a lever, which is guided in an elongated hole, is articulated on the hook. When the hook is inserted, this lever inclines to such an extent that the hook can be inserted into the opening of the cladding part, provided the opening is very large, in particular with a significantly larger cross-section, in particular higher. When lowering the hook in the cladding part, the lever should be through a Tilt the frictional force into a vertical position and, as in the first embodiment, prevent the hook from lifting. Since the pivoting of the lever can only be triggered by frictional contact and no clear end position is guaranteed, the console cannot be secured either, in particular there is no visual control of the position of the lever.
In both embodiments, a wedge must additionally and imperatively be hammered through the upper crossbeam of the climbing bracket and the carrier of the hook, which is slidably mounted in the crossbeam, in order to prevent the horizontal displacement and thus the risk of the safety lever tilting. To attach a wedge, the construction worker has to bend over the wall as before and knock in the wedge below the crown of the partial structures on the climbing brackets. Furthermore, it cannot be seen in which way the securing lever later, when the climbing bracket is to be released from the wall again, is released from the securing position and can thus be pulled out of the cladding part. In addition, there is an acute risk that the wedge will either be forgotten to attach or the wedge will only be hammered in incompletely, so that the wedge and the safety lever can be released from its clamped position due to the vibration during the subsequent concreting work. Furthermore, when concreting above the horizontal traverse, concrete can get through the opening, which is extra large for the purpose of inserting the lever, into the cladding part and harden there, so that the hook remains in the wall and cannot be released.
In general, it can be stated that all known climbing consoles require a securing element to be operated separately, such as a wedge, to ensure their safety.

From the EP 19162871.8 a method is also known for independently activatable connection of a climbing bracket with an anchoring device, in which after the hook has been hung in an anchoring device, the climbing bracket is pulled onto the wall without the construction worker and can then no longer be removed from the anchoring by lifting the bracket . It is true that the attachment of the console to the wall with such a device is very secure. In the event of an extraordinary load on the console at its outer end, where usually little or no load acts, the upper leg may incline slightly and safely. Furthermore, however, the automatic securing of the fastening is not visible from the outside for the construction worker and consequently, in particular in the event of soiling, safety cannot be guaranteed.

One object of the present invention is therefore to create an optically easily recognizable additional securing element which clearly shows the complete fastening.

This object is achieved by a method according to the features of patent claim 1, a system according to the features of patent claim 4 and a climbing bracket according to the features of patent claim 7.

Advantageous refinements of the invention are described in the claims which are dependent on the independent claims 1, 4 and 7, respectively.

When inserting the hook on the climbing bracket in the anchoring device, this essentially becomes two-armed formed securing element pivoted upwards about an axis on the hook, namely so far that the first leg of the two-armed securing element reaches a cross-sectional widening located above and behind the insertion opening for the hook. A latch can then be inserted which, on the one hand, indicates that the console is being fastened correctly and, on the other hand, prevents the securing element from being released from the securing position. Furthermore, the bolt can also pivot the securing element further and thereby prevent the crossbeam on the console from tilting. The pulling out of the climbing bracket from the anchoring device is already prevented when the hook is only partially inserted, because at this point in time the vertical extension of the hook due to the raised safety lever is greater than the height of the opening in the anchoring device, which is not the case with any known climbing bracket with safety elements Case is.
The release of the climbing bracket after completion of the tasks assigned to it, namely the supporting of formwork panels for the further concreting of the already created sub-structures, can only take place when the inserted sliding bolt, which is accessible and visible from the outside, locks the two-armed securing element in its raised position Position is withdrawn.
Furthermore, in a further advantageous embodiment of the invention, the climbing bracket without any action on the part of the construction worker succeeds in that it always comes into contact with the wall of the sub-structure after being inserted when lowering, that is, the climbing bracket is pulled horizontally towards the wall as soon as the Climbing console is no longer used by the construction worker in the horizontal one Insertion is held. The pulling against the wall takes place inevitably and essentially independently of how far the anchoring device is arranged from the surface of the wall in which it is set in concrete. Inaccuracies when setting the anchoring device are eliminated.
The hook on the climbing bracket is preferably composed of two parallel elements, between which the securing element is pivotably inserted. Alternatively, the securing element can also be located on the side of a simple hook.
With a wedge-shaped bolt which penetrates the housing in which the hook and the securing element are arranged, the movement of the securing element, ie the pivoting securing element, can consequently be released and prevented after the console has been hung in without any effort. The bolt always remains in its guide on the housing and can therefore not be lost. By pushing in the bolt, only the pivoting range of the rear end of the securing element is blocked. Since the bolt does not have to exert any forces on the securing element, it can easily be pushed into the locking position by hand or with a tool and moved out of this again. If the console is subjected to a load, in particular a higher load that does not act on the console from a workload from above, the securing element jams on the bolt. However, this jamming is automatically lifted as soon as the load on the console is lifted.

In Figure 1 a climbing bracket 1 is shown schematically and in sections on the left side. Up in Figure 1 the upper leg 3, which serves as a guide and support element, is visible. On the right-hand side, the vertical leg 5 for supporting the climbing bracket 1 on a sub-structure 21 is partially shown. A housing 7, in which a guide support 9 for a hook 11 is slidably mounted, is arranged on the upper leg 3, offset slightly downwards. Alternatively, the guide support 9 can also be arranged integrated in the upper leg 3 if it has a suitably large cross-section. In the preferred embodiment of the invention, the guide support 9 with the hook 11 or hook-shaped end is slidably mounted on the climbing bracket 1 on guide tracks inclined to the horizontal with an inclination angle to the horizontal of> 45 °. The guide tracks are formed by inclined slots 13 which are formed in the guide carrier 9 and at least one further, preferably two further slots 41, which are in the Figures 7.8 are visible and embedded in the housing 7. The slots 13 are traversed by two bolts 15 fixedly mounted in the housing 7 and form a first longitudinal guide track for the guide carrier 9. A pin 17, which is axially movably mounted in the first embodiment and which is axially displaceable in the guide carrier 9 against a spring force, and penetrates a further safety bolt 43 inserted in the guide carrier 9 the third slots 41 in the housing 7. The three or preferably four parallel slots 13; 41 consequently form the parallel guide for the guide support 9 and the hook 11 arranged on it ( Fig. 6 ).
Furthermore, a two-armed securing element 19 with a first arm 19 'and a second arm 19 "is pivotably mounted on the guide support 9 on a shaft 48 arranged thereon. The two-armed securing element 19 is in the rest or starting position with its first arm 19' in the Essentially within the outline of the hook 11, that is, the arm 19 'does not protrude beyond the outer contour of the hook 11 either on its upper edge or on its lower edge. In other words, the height h of the hook 11 in the region of its front end also determines the height or Height expansion of the securing element 19.
The second arm 19 ″ of the securing element 19 protrudes beyond the upper edge of the guide support 9 in the rest and initial position (cf. Fig. 2 + 8a).
In the extension of the guide support 9 or hook 11 is shown in Figure 1 also shown in vertical section a partial structure 21, for example a wall made of concrete, in which an anchoring device 23 is set in concrete. The anchoring device 23 has on the left in FIG Fig. 1-5 an opening 25, the height H of which is slightly greater than the height h of the hook 11 on the guide support 9. The width B of the opening 25 is slightly greater than the width of the hook 11, which is preferably two spaced apart arranged metal sheets is constructed and between which the fuse element 19 is located. These dimensions make it possible to move the hook 11 or guide support 9 and the securing element 19 between them horizontally in direction X ( Fig. 1 ) into the anchoring device 23. The hook 11 can also be constructed from a single sheet metal part or from two parallel sheet metal parts connected at the hook-shaped end 11 '.

the Figure 2 shows the climbing bracket 1 after the hook 11 has been inserted horizontally into the anchoring device 23 by an operator, for example the construction worker, carried on the climbing bracket or on a shuttering holder arranged displaceably on the carrier 3. It can be seen that the upper edge of the guide support 9 and hook 11 lie with only a little play on the upper wall 27 behind the opening 25 and the lower end 11 'of the hook 11 is now guided past the lower wall 29 in the enlarged interior or hollow body 65 of the Anchoring device 23 is located. The lower end of the first arm 19 'of the securing element 19, which is approximately the same height as the end 11', also slides over the bottom section 29 of the insertion area 26 of the anchoring device 23 Figures 1 and 2 The illustrated positions of the elements exist as long as the climbing bracket 1 is still being carried by the operator, that is, as long as the mass of the climbing bracket 1 does not move it downwards. The climbing bracket 1 would consequently be able to be guided out of the anchoring device 11 again when carried by the construction worker in this position. Next is in Figure 2 it can be seen that between the front edge of the vertical leg 5 of the climbing bracket 1 and the Surface 21 'of the wall 21 with the opening 25 on the anchoring device 23, there is a distance A of, for example, 8 mm after the front end of the hook 11 is in the vicinity of the rear wall of the anchoring device 23 of the hollow body 65.

Alternatively, instead of the securing element 19, which can rotate around the axis of the screw 17, the securing element 19 can also be slidably fastened in a linear guide on the guide carrier 9 and, instead of a rotary movement, perform an upward sliding movement. In a further embodiment, also not shown, the securing element 19 could be hinged to the guide support 9 so as to be pivotable about a vertical axis and could be pivoted out to the side when the hook 11 is lowered and consequently prevent the hook from being pulled out (not shown).

As soon as the operator, who is, for example, standing upright on the sub-structure 23, holds the climbing bracket 1, e.g. on a shuttering plate carrier 55 placed on the first leg 3 of the climbing bracket 1 ( Fig. 20 ), which allows climbing bracket 1 to slide downwards, i.e. no longer holds it (as in Fig. 19 ), the securing element 19 on the right arm 19 'of the securing element 19 is pressed upwards by contact with the bottom section 29 and rotates counterclockwise around the axis of the shaft 48 until the guide support 9 with its lower edge 9' is in the area behind the hook 11 rests on the bottom section 29. It should be noted that with the beginning of the lowering of the climbing bracket 1 in the anchoring device 23, the rotation or displacement of the securing element 19 and the spur 31 arranged on the upper side of the arm 19, for example, begin immediately immediately protrudes over the upper edge of the guide support 9 and then the height h of the hook 11, guide support 9 and securing element 19 is increased and consequently the hook 11 can no longer slide out horizontally through the opening cross-section with the height H of the anchoring device 23 from this moment on .
When the hook 11 is lowered further, it engages behind an approximately vertical section 33 at the end of the insertion channel 29 in the anchoring device 23. The left end, ie the arm 19 ″ of the two-armed securing element 19 pivots counterclockwise downwards when it is lowered and comes into the area of a washer 35 on a securing bolt 45 and forcibly engages with the concave surface 46. The securing element 19 is securely fixed (cf. Figures 8a, 8b ).
Mounting the guide support 9 in the guide tracks formed by the slots 13, 41, which is inclined to the vertical, is particularly advantageous because this pulls the hook 11 with the guide support 9 to the left when the climbing bracket 1 is lowered into the housing 7 and consequently on the one hand, the vertical leg 5 of the climbing bracket 1 is attracted to the surface of the sub-structure 21 and, on the other hand, the hook 11 in the anchoring device 23 is moved to the left, so that the hook 11 comes into full contact in the anchoring device 23. The end of the hook 11 is also pulled to the left and there comes into close contact with a vertically extending section on the anchoring device 23.
The climbing bracket 1 is consequently automatic and compulsory without any additional action by the construction worker, simply by pushing it into the anchoring device 23 and then lowering it the release held by gravity inextricably in the anchoring device 23 on the sub-structure 21 and can no longer be released by external forces acting on the climbing bracket 1 from below, from obliquely below or from above or from the side. The climbing bracket 1 can only be released again by manual intervention on the securing bolt 45, as will be described later.

the Figures 4 and 5 correspond in principle to Figure 3 . They differ in that the anchoring device 23 or the edge of its opening 25 does not lie exactly in the surface of the component parts 21, but is set back by a few millimeters for whatever reason. The mounting of the climbing bracket 1 is nevertheless carried out in the same way and its securing in the mounted position corresponds to that in Figure 3 . The difference visible from the outside is that the relative displacement in the horizontal direction between the climbing bracket 1 and the anchoring device 23 is smaller. This can be seen that the bolts 15 have slid less far up in the slot 13 or the climbing bracket 1 has moved less far downwards

Another special feature, in particular a further advantage of the arrangement according to the invention, is that the opening 25 on the anchoring device 23 is completely covered by the vertical leg 5 of the climbing bracket 1 and therefore no concrete or concrete water through the opening 25 into the interior of the anchoring device 23 when concreting get there and damage the fuse element 19 or make it unusable.

Of course, the sliding movement of the hook 11 with the guide carrier 9 in the direction of the subassemblies 21 could also take place horizontally, as is the case in the prior art if the slots 13, 41, 43 were arranged horizontally. However, the major disadvantage would then have to be accepted that the climbing bracket 1 would have to be pulled up to the subassembly 21, for example in a conventional manner with a wedge. This means that the operator would necessarily have to perform an additional action in a bent body position that is likely to fall over, which can also be forgotten.
Nevertheless, even if the hook 9 is not pulled in with a wedge, the climbing bracket 1 according to the present invention would be held securely on the sub-structure 21, because the securing element 19 inevitably catches the hook 11 when the construction worker is released and the lowering begins (even without pulling it) is held immovably in the anchoring device 23 (no illustration).

In the Figure 6 the climbing bracket 1 is again shown in perspective at its hook-side end. It can be seen from this figure that the horizontal leg 3 is at least laterally encompassed by the housing 7 at the end on the hook side. The housing 7 is preferably widened at its upper edge by laterally outwardly projecting tabs 47 and likewise preferably also extend over the hook-side edge of the horizontal leg 3 and the vertical leg 5 in the form of a second tab 49. These two tabs 47, 49, the are arranged in pairs, the sides protect the Elements protruding from the housing 7, namely the helical bolts 15 which cross the slots 13 on the guide support 9, the securing bolt 45 and the screw 17 and, of course, the third and fourth slots 41 visible at the top in this figure, which are embedded in the side walls of the housing 7 on both sides are (see also Fig. 7 +8). The housing 7 is preferably also closed on the rear by a wall 51.
In Figure 7 the hook 11 is in the starting position and the securing element 19 is consequently in its rest position (only protrudes below with its nose 19 'under the guide support 9). The screw 17 and the securing bolt 45 rest on the lower end of the two slots 41. In the Figure 8 the guide support 9 with the hook 11 is in the position as it is in the anchoring device 23 after it has been pushed in through the opening 25 and lowered. The anchoring device 1 has been omitted here for the sake of clarity. The screw 17 and the securing bolt 45 have now slid relatively upwards, since the hook 11 has been pushed upwards relative to the horizontal leg 3 of the climbing bracket 1 in the housing 7. In the latter position, i.e. the lowered climbing bracket 1 in the anchoring device 23, the securing element 19 is fixed to the disk 35 on the securing bolt 45 through an indentation 39 on the securing element 19 ( Figure 8b ). To detach the climbing bracket 1 from the sub-structure 21, the construction worker must therefore loosen the connection between the disk 35 on the safety bolt 45 and the safety element 19 so that the safety element 19 can pivot clockwise and thereby move back between the two plates of the hook 11. In the pivoted position according to the Figures 1,2 , 4th and 7th the climbing bracket 1 can consequently be lifted and then pulled out of the anchoring device 23. The securing element 19 is released in that the disk 35 is axially displaced by the securing bolt 45, so that the lower lug 53 on the securing element 19 (see FIG Fig. 2 ) is no longer held back by the disk 35 and can slide past the shaft of the securing bolt 45. The securing bolt 45 or the washer 35 can only be displaced axially against the force of a spring (the spring is not shown).

In a further embodiment of the invention, the securing bolt 45 and the disk attached to it are replaced by a bolt 87 in the form of an acute-angled wedge, which can be pushed into the housing 7 after the climbing bracket 1 has been lowered and the climbing bracket is automatically pulled up against a wall.

Recesses 89 corresponding to the cross section of the bolt 87 are formed on the side walls of the housing 7. How out Figure 27 As can be seen, a stepped edge 95 is formed on the rear leg 19 ″. The front region 19 'of the bolt 19 is in the insertion position, ie the position when the console is hung on an anchoring device 13 in overlap with the hook 11. The upper edge of section 19 'lies essentially in front of the upper edge of the hook ( Figure 27 ). The edge 95 at the rear end 19 ″ of the bolt 19 is pivoted upwards and its edge areas are essentially vertical. The latch 87 as it is in the Figures 24 and 26 is clearly shown, passes through the housing 7 only with its support end. It is held in this position by a Bolt 99, which prevents the bolt 87 from being pulled back further from the housing 7.
As in Figure 27 shown, the locking lever can be pivoted counterclockwise in this locking position (see. Arrow 101). The bolt 87 therefore does not prevent the securing element 19 from being pivoted when the console is inserted and subsequently lowered with respect to the anchoring device 23.
From the Figures 32 It can be seen that the bolt 87 along its upper edge 87 'has a greater width b than in the lower area 93. This wider area 91 is consequently outside the pivoting range of the securing lever 19. The bolt 87 consequently has no influence on the pivoting of the securing element and this also does not prevent the pivoting movement, which then moves the front end 19 'of the pivot element into a raised position according to FIGS Figures 28 to 31 brings.

As soon as the raised position of the securing element 19 is reached, ie when the console is securely held in the anchoring device 23, because on the one hand the hook comes to lie below the opening on the anchoring element and because the raised securing lever with its spur 31 above the insertion opening 25 is in contact with has reached the housing of the anchoring device 23. Due to the guide slots 13 at an acute angle to the vertical, on which the hook 11 and the securing element 19 are guided through the guide carrier 9, the securing lever is already secured a priori by frictional engagement.
In this pushed-in position of the secured console, the bolt 87 can now be inserted further into the housing 7 without forces having to be applied, which influence the securing element 19. This is possible because the bolt 87 is step-shaped and can thus be inserted past the edge 95 in accordance with the steps. The bolt does not have to absorb any forces when it is pushed in and can consequently be moved easily. If the bolt 87 is fully inserted, it only comes into operation when forces act on the bracket 1 which are not caused by a load on the upper leg 3, but in particular when indefinable forces act on the bracket from below. The position of the bolt 87 shows the construction worker whether the automatic, automatic locking, which took place in the anchoring device 23 when the climbing bracket 1 was lowered, worked properly. For this reason, it is also possible to pull out the bolt 87 without exerting force after the work has been completed.
As mentioned at the beginning, the climbing bracket 1 serves as a temporary carrier on the one hand for a scaffolding board and on the other hand as a device for fastening a shuttering panel carrier 55 for creating the wall above the sub-structures 21. The in the Figures 9-21 Shuttering plates (not shown) are supported by the shuttering plate carrier 55, which is displaceable on the horizontal leg 3 relative to the climbing bracket 1. The shuttering plate carrier 55 comprises a U-shaped guide shoe 57 which is pushed horizontally onto the horizontal leg 3 of the climbing bracket 1 from the side and is fixed laterally and below by suitable means.
The guide shoe 57 ( Fig. 11 , 12th ) comprises a side wall 59, an upper guide wall 61 and a lower guide wall 63 serving as a sliding shoe, which stand in a U-shape relative to one another and are connected to one another. At the The side wall 59 forming the base of the U can be laterally joined by a safety and release plate 65. Their function and shape will be described later.
On the lower guide wall 63, a pivotable locking plate 69 is held in a downwardly projecting tab or in an opening 73 attached to it. Furthermore, a first passage 75 is embedded in the upper guide wall 61 and lies above a second passage 77 which is formed in the lower guide wall 63. With a slide 79, the cross-sectional area of which is slightly smaller than the cross-section of the two passages 75, 77, the guide shoe 57 can be closed to form a rectangular tube when this is pushed onto the upper leg 3 of the climbing bracket 1. The locking plate 69 can then be pushed through the opening 73 and a recess 81 through a slide 79. The locking plate 69 is captively connected to the guide shoe 57 by a locking bar 83 formed at its end. The narrow ends of the upper guide wall 61 and the lower guide wall 63 are preferably bent slightly out of their plane. The locking plate 69, which interacts with the slide 79, prevents the vertical arm 85 of the shuttering plate carrier 55 from being absorbed in the event of a force F which acts on the vertical arm 85 of the shuttering plate carrier 55 from the liquid concrete behind the shuttering plate. This ensures that the shuttering plate carrier 55 can be moved with little friction on the upper leg 3 of the climbing bracket before and after concreting as soon as the conical locking plate 69 is out of the locking position ( Fig. 15 ) in the
Unlocked position ( Fig. 16 and 17th ) is withdrawn. With the locking plate 69 or its wedge-shaped Cross-sectional shape (see in particular Fig. 17 ), the shuttering plate carrier 55 can be fixed on the climbing bracket 1 in its working position, ie pushed up to a shuttering plate. By pulling out the wedge-shaped locking plate 69, the clamping effect on the slide 79 is also canceled. As long as the slide 79 is pushed into the upper and lower passage 75, 77, the shut-off plate carrier 55 is securely held on the climbing bracket 1, but it is displaceable.

The safety and release plate 65, which is formed on the side wall 59 on the guide shoe 57, has two tasks. In the working position, when the shuttering plate carrier 55 is pushed against the wall of the sub-structure 21 and is only spaced apart from it by a shuttering plate (not shown), the safety and release plate 65 covers the bolt 45 just enough so that it is not accidentally actuated or can be actuated and leads to the release of the latching within the anchoring device 23.
After the ceiling has been poured above the sub-structure 21 and the concrete has solidified, the shuttering plate carriers 55 arranged next to one another on the climbing brackets 1 are pushed away from the wall by knocking out the locking plate 69 on the climbing bracket 1. The shuttering panels (not shown) are then removed. The formwork panels are still secured in that they are supported on the upper leg 3 of the climbing bracket 1 so that they cannot slide downwards. After the shuttering panels or boards have been removed, the operator, ie the construction worker, can stand the shuttering panel carrier 55 on the vertical arm 85 on the newly concreted ceiling towards itself, that is, in the direction of the sub-structures 21. The cranked safety and release plate 65 slides over the safety bolt 45 and presses it into the housing 7. As a result, with the securing bolt 45, the disk 35 is brought out of engagement with the securing element 19, 19 'and the locking of the securing element 19, which was previously held in the raised position, is released. The securing element 19 now rotates clockwise and disappears between the two plates forming the hook 11. The climbing bracket 1 can now be lifted and only then pushed or swiveled outwards, ie away from the sub-structure, without the construction worker having to bend over the edge of the sub-structure 21 (cf. Figures 18 to 20 ).

If no shut-off plate carrier 55 is mounted on the climbing console 1, the release is released after the end of use of the console 1 by pressing the securing bolt 45, e.g. with the thumb, or a blow with a hammer, the securing element 19 and falls clockwise between the two plates forming the hook 11, so that the climbing bracket 1 can easily be pulled out of the anchoring device 23 after it has been lifted.

In a further embodiment of the safety and release plate 65 according to FIGS Figures 22 and 23 is the upper flap 47 at its edge or its edges folded over by approx. 90 ° and is now parallel to the wall of the housing 7. Furthermore, the safety and release plate 65 at its front end is not only with a run-up area 66 over the entire height of the Safety and release plate 65 is provided, but an overhead section 68 runs parallel to the side wall 59.

When the shut-off plate carrier 55 is withdrawn, both elements, namely the safety and release plate 65 and their front edge regions 66 and 68, are out of contact with other elements of the device.
While the ceiling is being poured, the
Stop plate carrier 55 according to Figure 23 advanced to the right and the safety and release plate 65 covers with its run-up area 66 the safety bolt 45 and thus prevents an intentional or unintentional release of the locking mechanism with the hook 11. The section 68 is now under the folded down area of the first tab 47 and stands preferably in contact with them. So that the section 68 can slide easily under the folded flap 47, its end is bent slightly inward.

The purpose of this further embodiment of the shuttering panel carrier 55 is that during casting and already when the vertical arm 85 of the shuttering panel carrier 55 is braced, it transfers high forces to the guide shoe 57, reinforced by the lever. These forces transmitted to the guide shoe can be at least partially absorbed via the section 68 which engages under the bent tab 47, and thus a stiffening of the shuttering plate carrier 55 with respect to the climbing bracket 1 can be achieved.

In a further embodiment of the shuttering plate carrier 55 according to FIGS Figures 22 and 23 its vertical arm 85 is supported pivotably with respect to the vertical with two spaced spindles. The lower spindle 89 and the upper spindle 87 are connected to one another by a spindle carrier 91. At the ends of the spindle carrier 91 threaded bushings 93 and 95 are formed in which the The thread of the spindles 87 and 89 mesh. The output-side end of the lower spindle 89 is freely rotatably mounted in a spindle bearing 97 and axially secured against displacement of the lower spindle. The bore in the spindle bearing has play in relation to the diameter of the spindle in the region of the bore, which offers the possibility that the axis of the lower spindle is pivotably connected to the vertical arm 85 in a certain angular range. The upper spindle 87 is also carried in a bearing block 99 and secured against axial displacement. However, the end of the spindle 87 is not guided in a bore, but in a U-shaped recess in the bearing block 99. This embodiment makes it possible, after loosening a locking screw arranged at the end of the lower spindle 89, the two spindles 87 and 89 from the vertical Arm 85 to release.

With the two movably mounted spindles 87, the vertical arm 85 and thus the formwork board lying against it can be aligned exactly horizontally or at a certain angle to the horizontal. Consequently, with the shuttering panel support 55 according to the invention, a wall can be created which does not run in a vertical plane, but is inclined inwards or outwards to it.
