Abstract

The system for attaching a climbing bracket (1) to an anchoring device (23) embedded in a substructure comprises the climbing bracket (1) on which a hook (11) is slidably guided in the upper leg (3) and in which a safety element (19) attached to the hook (11) extends upwards or laterally from the cross-sectional area of ​​the hook (11) after the hook (11) has been inserted through the insertion channel (26) and thereby prevents the hook (11) from being withdrawn through the insertion channel (26).

Description

[0001] The invention relates to a method for automatically activating a secure connection of a climbing bracket to an anchoring device, a system for attaching a climbing bracket to an anchoring device embedded in a substructure, a climbing bracket, an anchoring device, and a formwork panel support.

[0002] The invention further relates to a method for automatically activating and securely connecting a climbing console to an anchoring device according to the preamble of claims 1, 6, and 8. The invention further relates to a climbing console according to the preamble of claims 3, 7, and 9. The invention further relates to an anchoring device according to the preamble of claim 12.

[0003] Climbing brackets of this type are used to install formwork at the edges of ceilings with minimal effort, to support wall formwork, especially large-area wall formwork panels, and / or to simultaneously erect scaffolding along the tops of walls, particularly partial structures. The climbing brackets are shaped like a right-angled triangle, one leg of which forms the upper, load-bearing crossbeam. The second leg rests against the wall or partial structure, and the hypotenuse or base of the triangle is designed as a strut. A hook is formed on the crossbeam at the junction of the two legs and extending along the crossbeam. The end of this hook engages in an anchoring device formed by a recess in the wall.These anchoring devices are attached to the formwork before the wall section is cast. A mounting pin is attached to the formwork with a nail, and then the opening in the anchoring device is slid onto the mounting pin. After the wall section is completed, the mounting pin, which is embedded in the wall surface, can be removed, thus exposing the opening of the anchoring device. The anchoring device extends behind the opening into the wall and, spaced apart from the opening, downwards over a further area. This allows the hook on the climbing bracket to be inserted through the opening and hooked onto the lower edge of the box and a section of wall located there. A climbing bracket-anchoring system constructed in this way can provide the required load-bearing capacity for the climbing bracket.However, the climbing bracket is only held in place by gravity, and if a crane load accidentally attaches to the climbing bracket from below and lifts it, the climbing bracket is not secured and can detach from the wall.

[0004] In a further development of such a climbing bracket anchoring system, a reinforcing bar is inserted into the box below its opening, and the hook on the climbing bracket is bent so that the bent section engages under the reinforcing bar. However, this only works if the hook has first been manually retracted with a wedge and the climbing bracket has been pulled firmly against the wall, thus making it more difficult to lift the climbing bracket, but not ensuring it is completely secure. In a further embodiment of the known climbing bracket, the hook is movable within the traverse, and after the hook has been inserted into the anchoring device, the climbing bracket can be additionally secured by means of a wedge that penetrates the traverse and retracts the hook.Such a climbing bracket, if properly attached, is relatively secure; however, the worker installing it must move over it, unsecured, outside the wall and below its top, driving the wedge through the crossbar and hook into place. Another known climbing bracket has a T-shaped hook permanently attached to it. To insert this climbing bracket into the anchoring device, it must be brought into a horizontal position, inserted through the horizontally arranged opening of the anchoring device, and then rotated 90°. Such a climbing bracket cannot be accidentally or forcefully removed from the wall; however, there is no way to ensure the bracket is snug against the wall at varying distances from the surface.EP 3 032 002 describes a climbing bracket and a formwork component for such a bracket. The climbing bracket comprises a frame and a movable hook within it. This hook can be engaged in the formwork component forming a wall recess and secured within the formwork component against detachment. For this purpose, both the formwork component and the hook must each include at least one passive locking element. Such a locking element can be a locking flap pivotally mounted in the formwork component. After the hook is inserted and lowered, the flap comes to rest between the upper surface of the formwork component and the upper edge of the hook, thus preventing the hook from being lifted. In a further embodiment of this prior art, a lever guided in an elongated hole is pivotally attached to the hook.This lever tilts when the hook is inserted, allowing the hook to be inserted into the opening of the formwork section, provided the opening is very large, particularly with a significantly larger cross-section, and especially taller. When the hook is lowered into the formwork section, the lever should tilt into a vertical position due to frictional force, thus preventing the hook from being lifted, as in the first embodiment. Since the lever's pivoting can only be triggered by frictional contact and no clear end position is guaranteed, securing the bracket is not ensured; in particular, there is no visual indication of the lever's position. In both embodiments, a wedge must additionally and necessarily be driven through the upper crossbeam of the climbing bracket and the hook support, which is slidably mounted in the crossbeam, to prevent horizontal displacement and thus the risk of the locking lever tilting.To insert a wedge, the construction worker must, as before, lean over the wall and drive the wedge into the climbing brackets below the top of the substructure. Furthermore, it is unclear how the locking lever will later be released from its locking position and thus pulled out of the formwork when the climbing bracket needs to be detached from the wall. There is also a significant risk that the wedge will either be forgotten or only partially driven in, allowing the wedge and locking lever to be dislodged from their clamped position by vibrations during subsequent concreting. Additionally, during concreting above the horizontal beam, concrete can seep through the extra-large opening (designed for inserting the lever) into the formwork and harden there, leaving the hook permanently embedded in the wall.

[0005] In general, it can be stated that all known climbing consoles require a separately operable safety element, such as a wedge, to ensure their safety.

[0006] One object of the present invention is to create a method for the automatically activatable secure connection of a climbing console with an anchoring device in which the climbing console, after the hook has been inserted into the anchoring device, secures itself automatically in the latter.

[0007] Another object of the present invention is to create a system which allows the construction worker to insert the climbing bracket into the anchoring device as before, without explanations or learning effort, and without further actions, i.e. without inserting safety elements such as a wedge, so that the climbing bracket is definitely secured to the wall after being hooked in.

[0008] Another object of the invention is to create a climbing bracket which, during the hanging process, is forcibly pulled against the wall or into the anchoring device without any manipulation by the construction worker, at the latest when the construction worker releases the climbing bracket, so that a play-free hold of the climbing bracket is ensured immediately and without the use of a wedge.

[0009] Another objective of the invention is to create a climbing bracket which inevitably and automatically eliminates the inaccuracies that arise when setting the anchoring device, or which presses the climbing bracket firmly against the wall and holds it securely in place, regardless of the position of the anchoring device.

[0010] Another objective of the invention is to create a climbing console in which an automatic

[0011] The safety element prevents the hook from being extended again after it has been lowered on the climbing console, without the possibility of active release by manual intervention.

[0012] Another object of the invention is to create an anchoring device for installation in a wall for anchoring a climbing bracket, in which the hook of the climbing bracket is secured against being pulled out both above and below the opening.

[0013] Another object of the invention is to create an anchoring device with such high strength that it can be anchored in the wall without additional reinforcing steel or the like.

[0014] The general object of the invention is therefore to create a self-secured or automatically securing climbing console whose safety devices do not need to be activated in a separate operation.

[0015] A further object of the invention is to create a formwork panel support which is easily slidable and lockable on the upper leg of the climbing bracket and with which, during the casting of the ceiling, the locking of the climbing bracket in the anchoring device is ensured by the fact that it cannot be released as long as the formwork panel support is pressed against the formwork, and with which, after completion of the concreting and removal of the formwork panel, the construction worker can, standing on the newly cast ceiling, unlock the climbing bracket and lead it out of the anchoring device.

[0016] These tasks are solved by a method according to the features of claim 1, a system according to the features of claim 4, a climbing console according to the features of claim 9, an anchoring device according to the features of claim 15 and a formwork plate support according to claim 19.

[0017] Advantageous embodiments of the invention are described in the dependent claims of the independent claims 1, 4, 9, 15 and 19.

[0018] When the hook on the climbing bracket is inserted into the anchoring device, the essentially two-armed locking element on the hook pivots upwards around an axis until the first arm engages a cross-sectional expansion located above the insertion opening for the hook. Simultaneously, the second arm of the two-armed locking element engages with a locking bolt, preventing the hook and climbing bracket from being removed from the anchoring device. Pulling the climbing bracket out of the anchoring device is prevented even with only partial insertion of the hook, because at this point the vertical extension of the hook and the locking lever is greater than the height of the opening in the anchoring device—a feature not found in any other known climbing bracket with locking elements.Of course, the securing element could also be pivoted laterally on the hook and extend into a space located to the side of the insertion channel when inserted into the anchoring device.

[0019] Releasing the climbing bracket after it has completed its assigned task—namely, supporting formwork panels for the continued concreting of the already constructed sections—is only possible if the locking bolt, accessible from the outside, is pressed against the force of a spring on the crossbeam or the upper, horizontal leg. This releases the locking mechanism of the two-armed locking element in its raised or laterally extended position. However, the locking mechanism can only be released if the climbing bracket is no longer bearing any formwork load and is first raised vertically. In other words, even if the locking bolt is intentionally or unintentionally activated, the climbing bracket remains securely held in the anchoring device.

[0020] Furthermore, in another advantageous embodiment of the invention, the climbing bracket automatically comes into a tight fit with the wall of the substructure without any intervention from the construction worker. This means that the climbing bracket is pulled horizontally towards the wall as soon as it is no longer being held by the construction worker. This pulling towards the wall occurs automatically and regardless of how far the anchoring device is from the surface of the wall in which it is embedded. Inaccuracies in the placement of the anchoring device are thus eliminated.

[0021] The anchoring device, which is advantageously made of steel, has a small width in relation to its height, its internal dimension essentially corresponding to the width of the hook and the securing element arranged next to it.

[0022] Embossed, outwardly projecting ribs or bumps achieve a pull-out strength greater than that of prior art. The anchoring device can be produced cost-effectively and to a high quality standard in a step press from coil in just a few stamping and deep-drawing strokes from two interconnected halves. Preferably, the hook on the climbing bracket is composed of two parallel elements between which the locking element is pivotably inserted. Alternatively, the locking element can also be positioned laterally to a simple hook. Due to the low mass and narrow width of the anchoring device, the weakening of the structural components is negligible, and on the side of the anchoring device's opening, it is only minimally covered by the concrete mass of the wall, thus preventing spalling due to insufficient concrete cover or high loads.The anchoring device has a relatively long, channel-like insertion area in which the guide for the hook can rest after the hook is inserted, and within which the locking element prevents the climbing bracket from being lifted by the locking element. Furthermore, once the hook is inserted into the anchoring device and lowered, the second leg of the locking element is prevented from pivoting upwards, or rather, the pivoted locking lever (i.e., the first leg) cannot pivot back downwards and allow the hook to be pulled out of the anchor.

[0023] The invention is explained in more detail using exemplary embodiments. These show: Figure 1: A sectional view of the corner area of ​​a climbing bracket with the hook and the safety element, and, spaced apart from this, a section of a wall with an embedded anchoring device.

[0024] In Figure 1 A climbing console 1 is shown schematically and in part on the left side. Above in Figure 1The upper leg 3, which serves as a guide and support element, is visible. On the right side, the vertical leg 5 for supporting the climbing bracket 1 on a substructure 21 is partially shown. Slightly offset downwards, a housing 7 is arranged on the upper leg 3, in which a guide carrier 9 for a hook 11 is slidably mounted. Alternatively, the guide carrier 9 can also be integrated into the upper leg 3 if it has a sufficiently large cross-section. In the preferred embodiment of the invention, the guide carrier 9 with the hook 11 or hook-shaped end is slidably mounted on the climbing bracket 1 on guide tracks inclined to the horizontal at an angle of inclination of >45° to the horizontal. 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 located in the Figures 7, 8visible and recessed 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. An axially movable pin 17, which is axially displaceable in the guide carrier 9 against a spring force, and a further safety bolt 43 inserted in the guide carrier 9 penetrate the third slots 41 in the housing 7. The three or preferably four parallel slots 13; 41 thus form the parallel guide for the guide carrier 9 and the hook 11 arranged thereon ( Fig. 6 ).

[0025] Furthermore, a two-armed locking element 19, with a first arm 19' and a second arm 19", is pivotably mounted on a shaft 48 on the guide carrier 9. In its rest or starting position, the two-armed locking element 19 lies with its first arm 19' essentially within the outline of the hook 11; that is, the arm 19' does not project beyond the outer contour of the hook 11 at either its upper or lower edge. Conversely, the height h of the hook 11 in the region of its front end also determines the height or vertical extent of the locking element 19.

[0026] The second arm 19" of the locking element 19 extends beyond the upper edge of the guide carrier 9 in the rest and starting position (cf. Fig. 2 + 8a). The second arm 19" lies completely within the outline of the climbing console 1.

[0027] In the extension of the guide carrier 9 or hook 11, there is in Figure 1Also shown in vertical section is a partial structure 21, e.g., a concrete wall, in which an anchoring device 23 is embedded. The exact construction of the anchoring device 23 will be described later. The anchoring device 23 has on the left side in Figs. 1-5 An opening 25, the height H of which is slightly greater than the height h of the hook 11 or guide carrier 9. The width B of the opening 25 is slightly greater than the width of the hook 11, which is preferably constructed from two spaced-apart plates with the locking element 19 located between them. These dimensions allow the hook 11 or guide carrier 9 and the locking element 19 located between them to be moved horizontally in direction X with minimal play. Fig. 1 ) to be inserted into the anchoring device 23. The hook 11 can also be made from a single sheet metal part or from two parallel sheet metal parts connected at the hook-shaped end 11'.

[0028] The Figure 2 The climbing console 1 is shown after the hook 11, carried by an operator, e.g., a construction worker, on the climbing console or on a formwork holder slidably arranged on the support 3, has been inserted horizontally into the anchoring device 23. It can be seen that the upper edge of the guide carrier 9 and hook 11 lie with only slight play against the upper wall 27 behind the opening 25, and the lower end 11' of the hook 11, guided past the lower wall 29, now lies in the extended interior or hollow body 65 of the anchoring device 23. The lower end of the first arm 19' of the securing element 19, which lies at 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. The Figures 1 and 2The depicted positions of the elements exist as long as the climbing console 1 is still being carried by the operator, that is, as long as the mass of the climbing console 1 does not shift it downwards. Consequently, the climbing console 1 could be withdrawn from the anchoring device 11 in this position while being carried by the construction worker. Furthermore, in Figure 2 It is evident 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 located near the rear wall of the anchoring device 23 of the hollow body 65.

[0029] Alternatively, instead of the locking element 19, which can rotate about the axis of the screw 17, the locking element 19 can also be slidably mounted in a linear guide on the guide carrier 9 and perform an upward sliding movement instead of a rotational movement. In a further embodiment, also not shown, the locking element 19 could be pivotally mounted on the guide carrier 9 about a horizontal axis and be able to pivot laterally when the hook 11 is lowered, thus preventing the hook from being pulled out.

[0030] As soon as the operator, who is standing upright on the substructure 23, for example, holds the climbing console 1 on a formwork plate support 55 placed on the first leg 3 of the climbing console 1 ( Fig. 20 ), allowing the climbing console 1 to slide downwards, i.e., no longer holding it in place (as in Fig. 19The locking element 19 is pushed upwards by the right arm 19' of the locking element 19 through contact with the base section 29 and rotates counterclockwise around the axis of the shaft 48 until the guide carrier 9 rests with its lower edge 9' on the base section 29 in the area behind the hook 11. It should be noted that as soon as the lowering of the climbing bracket 1 in the anchoring device 23 begins, the rotation or displacement of the locking element 19 immediately commences, and the spur 31, e.g., located on the upper side of the arm 19, immediately projects beyond the upper edge of the guide carrier 9. Consequently, the height h of the hook 11, guide carrier 9, and locking element 19 is increased, and the hook 11 can no longer slide through the opening cross-section of height H in the anchoring device 23 from this moment onward.As the hook 11 is lowered further, it engages an approximately vertical section 33 at the end of the insertion channel 29 in the anchoring device 23. The left end, i.e., the arm 19" of the two-armed locking element 19, pivots counterclockwise downwards as it is lowered and comes to rest in the area of ​​a disc 35 on a locking bolt 45, where it engages with the concave surface 46. The locking element 19 is thus securely fixed (cf. ). Fig. 8a, 8b) .

[0031] Mounting the guide carrier 9 in the guide tracks formed by the slots 13, 41, which are inclined to the vertical, is particularly advantageous because it causes the hook 11 and the guide carrier 9 to be pulled to the left when the climbing bracket 1 is lowered in the housing 7. Consequently, on the one hand, the vertical leg 5 of the climbing bracket 1 is drawn against the surface of the substructure 21, and on the other hand, the hook 11 is moved to the left in the anchoring device 23, so that the hook 11 comes into full contact with the anchoring device 23. The end of the hook 11 is also pulled to the left and comes into full contact with the anchoring device 23, with a vertically extending section.

[0032] The climbing bracket 1 is therefore automatically and forcibly held in place on the substructure 21 solely by its insertion into the anchoring device 23 and subsequent lowering by gravity after release, without any intervention from the construction worker. It cannot be released by external forces acting on the climbing bracket 1 from below, from an angle below, from above, or from the side. The climbing bracket 1 can only be released manually by operating the locking bolt 45, as described later.

[0033] The Figures 4 and 5 correspond in principle to the Figure 3They differ in that the anchoring device 23, or rather the edge of its opening 25, is not located exactly on the surface of the substructure 21, but is set back by a few millimeters for whatever reason. The climbing bracket 1 is nevertheless attached in the same way, and its securing in the attached position corresponds to that described in [reference missing]. Figure 3 The externally visible difference is that the relative horizontal displacement between climbing bracket 1 and anchoring device 23 is smaller. This is evident because the bolts 15 have slid less far upwards in slot 13, or conversely, the climbing bracket 1 has shifted less downwards.

[0034] Another special feature, and 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, during concreting, no concrete or concrete water can enter the interior of the anchoring device 23 through the opening 25 and damage or render unusable the securing element 19.

[0035] Of course, the sliding movement of the hook 11 with the guide carrier 9 towards the substructure 21 could also be horizontal, as is the case in the prior art when the slots 13, 41, 43 were arranged horizontally. However, this would entail the significant disadvantage that pulling the climbing bracket 1 towards the substructure 21 would have to be done in the conventional manner, for example, using a wedge. This means that the operator would necessarily have to perform an additional action in a bent-over and unstable position, which could also be forgotten.

[0036] Nevertheless, even if the hook 9 is not pulled in with a wedge, the climbing bracket 1 would be secured to the substructure 21 according to the present application, because the securing element 19 is inevitably held immovably in the anchoring device 23 immediately after insertion when the construction worker releases it and the lowering begins (even without pulling in) (no illustration).

[0037] In the Figure 6The climbing bracket 1 is shown again in perspective, partially at its hook-side end. This figure shows that the horizontal leg 3 is enclosed at least laterally by the housing 7 at the hook-side end. The housing 7 is preferably widened at its upper edge by laterally projecting tabs 47, and preferably also extends 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, which are arranged in pairs, protect the elements projecting laterally beyond the housing 7, namely the helical bolts 15 which pass through the slots 13 on the guide carrier 9, the locking bolt 45 and the screw 17, as well as, of course, the third and fourth slots 41 visible at the top of this figure, which are recessed on both sides in the side walls of the housing 7 (see also...). Fig. 7+8). ​​Preferably, the housing 7 is also closed at the rear by a wall 51. In Figure 7 The hook 11 is in its initial position and the locking element 19 is consequently in its rest position (only its nose 19' protrudes below the guide carrier 9). The screw 17 and the locking bolt 45 rest against the lower end of the two slots 41. In the Figure 8The guide carrier 9 with the hook 11 is in the position it is in after being inserted through the opening 25 and lowered into the anchoring device 23. The anchoring device 1 has been omitted here for clarity. The screw 17 and the locking bolt 45 have now slid upwards relatively, since the hook 11 has been pushed upwards relative to the horizontal leg 3 of the climbing bracket 1 in the housing 7. In this latter position, i.e., with the climbing bracket 1 lowered in the anchoring device 23, the locking element 19 is fixed to the disc 35 on the locking bolt 45 by a recess 39 on the locking element 19. Fig. 8bTo detach the climbing bracket 1 from the substructure 21, the construction worker must therefore release the connection between the disc 35 on the locking bolt 45 and the locking element 19 so that the locking element 19 can pivot clockwise and thus move back between the two plates of the hook 11. In the pivoted position according to the Figures 1, 2 , 4 and 7 The climbing console 1 can therefore be lifted and then pulled out of the anchoring device 23. The locking element 19 is released by axially displacing the disc 35 by the locking bolt 45, so that the lower lug 53 on the locking element 19 (see Fig. 2 ) is no longer held back by the disc 35 and can slide past the shaft of the locking bolt 45. The locking bolt 45 or the disc 35 can only be displaced axially against the force of a spring (the spring is not shown).

[0038] As mentioned at the beginning, the climbing console 1 serves as a temporary support on the one hand for a scaffold board and on the other hand as a device for attaching a formwork panel support 55 for constructing the wall above the substructure 21. The in the Figures 9-21 The formwork panels (not shown) are supported by the formwork panel support 55, which is slidable on the horizontal leg 3 relative to the climbing bracket 1. The formwork panel support 55 comprises a U-shaped guide shoe 57, which is slid horizontally onto the horizontal leg 3 of the climbing bracket 1 from the side and fixed laterally and downwards by suitable means.

[0039] The guide shoe 57 ( Fig. 11 , 12The assembly comprises a side wall 59, an upper guide wall 61, and a lower guide wall 63 serving as a sliding shoe, which are arranged in a U-shape and connected to each other. A safety and release plate 65 can be attached laterally to the side wall 59, which forms the base of the U. Its function and shape will be described later.

[0040] A pivotable locking plate 69 is held in the lower guide wall 63 and can be inserted into a downwardly projecting tab or an opening 73 attached to it. Furthermore, a first through-hole 75 is recessed in the upper guide wall 61, which lies above a second through-hole 77 formed in the lower guide wall 63. A slide 79, whose cross-sectional area is slightly smaller than the cross-section of the two through-holes 75 and 77, can close the guide shoe 57 into a rectangular tube when it is slid 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 by means of a slide 79. The locking plate 69 is captive and connected to the guide shoe 57 by a latch 83 formed at its end.Preferably, the narrow ends of the upper guide wall 61 and the lower guide wall 63 are slightly bent out of their plane. The locking plate 69, which interacts with the slide 79, prevents the absorption of a force F acting by the liquid concrete behind the formwork panel on the vertical arm 85 of the formwork panel support 55. This ensures that the formwork panel support 55 can be moved with low friction on the upper leg 3 of the climbing bracket before and after concreting, as soon as the conically shaped locking plate 69 is released from the locking position ( ). Fig. 15 ) into the unlocked position ( Fig. 16 and 17 ) is withdrawn. With the locking plate 69 or its wedge-shaped cross-sectional form (cf. in particular Fig. 17The formwork panel support 55 can be fixed to the climbing bracket 1 in its working position, i.e., pushed towards a formwork panel. Pulling out the wedge-shaped locking plate 69 also releases the clamping effect on the slide 79. As long as the slide 79 is inserted into the upper and lower openings 75, 77, the formwork panel support 55 is securely held on the climbing bracket 1, but it is still movable.

[0041] The locking and release plate 65, which is integrally formed on the side wall 59 at the guide shoe 57, has two functions. In the working position, when the formwork panel support 55 is pushed against the wall of the substructure 21 and is spaced from it only by a (not shown) formwork panel, the locking and release plate 65 covers the bolt 45 just enough to prevent it from being unintentionally actuated and causing the release of the locking mechanism within the anchoring device 23.

[0042] After the slab above substructure 21 has been poured and the concrete has set, the adjacent formwork panel supports 55 are pushed away from the wall on the climbing brackets 1 by knocking out the locking plate 69 on the climbing bracket 1. The formwork panels are then removed (not shown). The formwork panels remain secured by being supported on the upper leg 3 of the climbing bracket 1, preventing them from sliding downwards. After removing the formwork panels or boards, the operator, i.e., the construction worker, standing on the newly poured slab, can move the formwork panel support 55 towards them, i.e., towards substructure 21, by its vertical arm 85. During this movement, the angled locking and release plate 65 slides over the locking bolt 45 and presses it into the housing 7.This causes the locking bolt 45 to disengage the disc 35 from the locking element 19,19' and releases the locking mechanism of the locking element 19, which was previously held in the raised position. The locking element 19 now rotates clockwise and disappears between the two plates forming the hook 11. Now the climbing bracket 1 can be lifted and only then pushed or swung outwards, i.e., away from the substructure, without the construction worker having to lean over the edge of the substructure 21 (cf. ). Figures 18 to 20 ).

[0043] If no formwork plate support 55 is mounted on the climbing console 1, the locking element 19 is released after the end of use of the console 1 by pressing on the locking bolt 45, e.g. with the thumb, or by striking it with a hammer, and falls clockwise between the two plates forming the hook 11, so that the climbing console 1 can be easily pulled out of the anchoring device 23 after lifting.

[0044] In a further embodiment of the safety and release plate 65 according to the Figure 22 and 23 The upper tab 47 is folded over by approximately 90° at its edge or edges and now lies parallel to the wall of the housing 7. Furthermore, the safety and release plate 65 is not only provided with a ramp area 66 over the entire height of the safety and release plate 65 at its front end, but an upper section 68 runs parallel to the side wall 59.

[0045] With the formwork support 55 retracted, both elements, namely the safety and release plate 65 and its front edge regions 66 and 68, are out of contact with other elements of the device. During the pouring of the ceiling, the formwork support 55 is in accordance with Figure 23 The locking and release plate 65 is advanced to the right, and its run-up area 66 covers the locking bolt 45, thereby preventing the locking mechanism with the hook 11 from being intentionally or unintentionally released. The section 68 now lies beneath the downwardly folded portion of the first tab 47 and is preferably in contact with it. To allow the section 68 to easily slide under the folded-over tab 47, its end is slightly bent inwards.

[0046] The purpose of this further design of the formwork plate support 55 is that, during casting and already during the clamping of the vertical arm 85 of the formwork plate support 55, this, reinforced by the lever, transmits high forces to the guide shoe 57.

[0047] These forces transmitted to the guide shoe can be absorbed at least partially via section 68, which engages under the bent tab 47, and thus a stiffening of the formwork plate support 55 with respect to the climbing bracket 1 can be achieved.

[0048] In a further embodiment of the formwork plate carrier 55 according to the Figure 22 and 23Its vertical arm 85 is pivotably supported with respect to the vertical by two spaced-apart spindles. The lower spindle 89 and the upper spindle 87 are connected to each other by a spindle carrier 91. Threaded bushings 93 and 95 are formed at the ends of the spindle carrier 91, in which the threads of the spindles 87 and 89 mesh, respectively. The output end of the lower spindle 89 is freely rotatable in a spindle bearing 97 and axially secured against displacement of the lower spindle. The bore in the spindle bearing has clearance relative to the diameter of the spindle in the area of ​​the bore, which allows the axis of the lower spindle to pivot within a certain angular range with the vertical arm 85. The upper spindle 87 is also supported 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 design makes it possible to detach the two spindles 87 and 89 from the vertical arm 85 after loosening a locking screw located at the end of the lower spindle 89.

[0049] The two movable spindles 87 allow the vertical arm 85, and thus the formwork panel resting against it, to be aligned precisely horizontally or at a certain angle to the horizontal. Consequently, the formwork panel support 55 according to the invention can be used to construct a wall that does not run in a vertical plane, but is inclined inwards or outwards towards it.
