EP4101984B1 - Support device and formwork - Google Patents

Description

The invention relates to a support device according to the preamble of claim 1.

Finally, the invention relates to a formwork with such a support device.

From the EP 2 210 979 B1 Such a formwork device is known, with which a cornice cap in particular can be manufactured on a bridge. When manufacturing concrete bridges, a pillar structure is fitted with a bridge superstructure. The bridge superstructure has a cantilever plate that protrudes laterally beyond the pillar structure. A cornice cap is concreted onto the laterally protruding edges of the cantilever plate. To produce the cornice cap, the space that the cornice cap is to occupy is surrounded by formwork elements consisting of an inner shield, an outer shield and a floor shield. In this state of the art, the inner shield, the outer shield and the bottom shield are mounted on a common formwork holder. The formwork holder is movably mounted on a column element, which is rigidly connected to a single work platform. In order to bring the formwork elements, i.e. the inner shield, the outer shield and the bottom shield, into the desired position for concreting ("forming"), the formwork holder can first be moved vertically using a first adjustment device until the formwork holder is attached to the formwork holder and is vertically aligned The upper end of the inner shield rests directly on the underside of the cantilever plate. The outer shield carrier carrying the outer shield is then moved horizontally using a second adjustment device until the floor shield is clamped between the outer shield and the inner shield. You can then begin filling the closed cornice cap with concrete.

After the concrete has solidified, the formwork removal process is carried out. For stripping the formwork, the formwork holder is initially given freedom of movement in the vertical direction using the first adjustment device. This allows the formwork holder to fall down within a limited range. However, the shields usually hold on so strongly Cornice cap so that the formwork holder does not initially fall. With the help of the second adjustment device, the outer shield carrier is then moved horizontally away from the cornice cap, whereby the cornice cap only rests on the inner shield and the floor shield. Finally, a tilting device is actuated, with which the formwork holder is tilted upwards around a tilting bearing. Tilting the formwork holder overcomes the adhesive forces between the shields and the cornice cap, peeling the inner shield from its upper end to its lower end. After tilting, the shields are spaced from the cornice cap, creating the switched-off state

However, the disadvantage is the design of the adjustment and tilting devices in this state of the art, which only allow the formwork holder to fall uncontrollably when stripping the formwork and only allow very limited geometry adjustment when concreting.

In a first variant, the first adjustment device comprises the EP 2 210 979 B1 a wedge-shaped slide, which slides with an upper wedge surface against a lower cross member of the formwork holder. In the switched-on position, the wedge-shaped carriage rests with a lower wedge surface on a roller mounted on the work platform bracket. If the wedge-shaped carriage is pulled outwards relative to the rest of the formwork holder by a lower spindle drive, the formwork holder moves upwards. If the wedge-shaped slide moves in the opposite direction, the formwork holder is lowered accordingly. However, when removing the formwork, the shields adhere so strongly to the cornice cap that has just been concreted that the formwork holder is not lowered. Therefore, the formwork holder is arranged in a raised position above the roller. The adhesive forces are only overcome when the external sign carrier is moved and the formwork holder is tilted upwards. The formwork holder falls back onto the roller. However, this uncontrolled falling back is disadvantageous for safety reasons. Another disadvantage is that the tilting means would not be suitable for adjusting different geometries of the cornice cap, because only tilting of the formwork holder upwards and exclusively for the Stripping process is provided.

In the EP 2 210 979 B1 A further embodiment variant is shown, in which the first adjustment device for the vertical adjustment of the formwork holder has a sliding bearing, which is moved along the lower cross member with the aid of a lever device. The formwork holder rests on the plain bearing via an underside of the lower cross member. The plain bearing slides on the underside of the lower cross member during movement. Even in this embodiment variant, however, the formwork holder is not lowered during stripping, because the formwork holder is in turn lifted off this plain bearing when the formwork elements still adhere to the cornice cap.

The further state of the art is provided by JP 2009 287286 A , EP 3 543 428 and A2, DE 295 20 671 U1 and JP 2015 017486 A educated.

In contrast, the object of the present invention is to alleviate or eliminate at least individual disadvantages of the prior art. The aim of the invention is preferably to create a support bracket, a support device and formwork equipped therewith, which can be flexibly adapted to the respective application and meets high safety requirements.

This object is achieved by a support device with the features of claim 1 and a formwork with the features of claim 12. Preferred embodiments of the invention are set out in the dependent claims.

For the purposes of this disclosure, the location and direction information, such as "top", "bottom", "horizontal", "vertical", refers to the installed use state of the support console on the support element.

According to the invention, the first adjusting device has a link guide with a guide slot for a guide bolt that runs obliquely to the horizontal support. By actuating the first adjusting device, the horizontal beam is raised or lowered relative to the support element of the formwork on which the horizontal beam is mounted in the intended state of use, ie moved in a direction essentially perpendicular to the horizontal beam, based on its essentially horizontal neutral position. According to the invention, the raising or lowering of the horizontal support is effected by a relative movement between the link guide and the guide pin, which is guided in the oblique guide slot, that is, running at an acute angle to the longitudinal axis of the horizontal support. Due to the oblique course of the guide slot, a displacement of the link guide relative to the guide pin causes the horizontal support to be raised or lowered. With the help of the link guide and the guide bolt, an adjustment movement of the first adjusting device in a first direction, preferably essentially in the longitudinal direction of the horizontal support, is converted into a height adjustment of the horizontal support. The lifting or lowering movement of the horizontal support can thus be achieved in a simple and reliable manner. In a preferred embodiment, the guide pin (related to the height adjustment) is mounted stationary, ie immovably, on the support element of the formwork. By activating the first adjusting device, the relative position between the guide bolt and the guide slot of the link guide is changed. When adjusting in the first direction, the link guide is pressed against the guide pin via the guide slot in such a way that the link guide and the associated horizontal support are moved up or down. It is particularly advantageous that both the raising and lowering of the horizontal beam is constantly guided. The position of the horizontal support relative to the support element is determined exclusively by the actuation position of the first adjustment device. If the support console is used in a formwork, in particular a cornice formwork, the position of the horizontal beam relative to the support element is independent of the adhesive forces between a formwork element mounted on the horizontal beam and the concrete body, which is cast with the formwork. To ensure positive guidance during lifting and To ensure lowering, the guide pin can be arranged laterally in the guide slot with essentially no play. The guide pin can therefore only be displaced in the longitudinal direction of the guide slot relative to the link guide. In addition, the link guide can press against a corresponding contact surface of the horizontal support essentially without play in the height direction, so that a movement of the link guide relative to the guide bolt is converted into a corresponding height adjustment of the horizontal support.

In a preferred embodiment, the first adjusting device has a first actuating element, preferably on the second longitudinal end of the horizontal beam facing away from the support element of the formwork. By actuating the first actuating element, in particular by a worker, the link guide is displaced relative to the guide pin, so that the desired lifting or lowering movement of the horizontal support, depending on the direction of actuation, is achieved.

The first adjusting device is preferably set up to adjust the height of the horizontal support as a whole, i.e. without changing its inclination with respect to the support element.

Preferably, the horizontal support is raised in one direction by actuating the first actuating element and lowered in the opposite direction by actuating the actuating element.

The first actuating element is preferably located at the second longitudinal end of the horizontal support, which is furthest away from the support element when the support console is mounted on the support element. This makes it easier to operate the first adjustment device in many applications, particularly when a work platform is provided below the support console.

The first adjusting device has a first force transmission element, with which, in particular by actuating the first actuating element, a force is applied essentially in the longitudinal direction of the horizontal support Scenery guide can be applied.

A first spindle is preferably provided as the first force transmission element, which engages with a first nut, which is in particular immovably connected to the link guide. A non-round contact point for a tool at the end of the first spindle, for example a hexagon, can be provided as the first actuating element. By turning the first spindle with the aid of the first actuating element, the spindle is screwed into the first nut to different extents. This changes the horizontal distance between the first actuating element and the first nut. This causes the link guide to shift relative to the guide pin, so that the horizontal beam is raised or lowered by the link guide.

Alternatively, a linear drive, for example a cylinder-piston drive or a servomotor, can be provided as the first force transmission element.

If the first force transmission element is extended in the longitudinal direction of the horizontal support, preferably over more than half, in particular over more than 3/4 of the length of the horizontal support, operation of the first adjusting device can be made possible closer to the second longitudinal end of the horizontal support. Due to the limited space available, this version is particularly favorable for many applications. By means of the first force transmission element, the horizontal beam can be raised or lowered to the same extent over its entire length from the first longitudinal end to the second longitudinal end.

In a preferred embodiment, the guide slot of the link guide extends at an angle of +15° to +75° or -15° to -75°, preferably from +30° to +60° or -30° to -60 °, in particular essentially +45° or -45°, to the longitudinal axis of the horizontal beam. The positive angle information (+) means that the guide slot, viewed from the first longitudinal end to the second longitudinal end of the horizontal beam, runs obliquely upwards. The negative angle information (-) mean that the guide slot, viewed from the first longitudinal end to the second longitudinal end of the horizontal beam, runs obliquely downwards. With this design, a favorable power transmission to the horizontal beam is achieved.

With the first adjustment device, a maximum height adjustment of at least +35 mm to -35 mm, in particular of at least +65 mm to -65 mm, can preferably be carried out in both directions starting from a neutral zero position of the guide bolt within the guide slot.

The guide slot is formed on a displacement part of the link guide, in particular on a displacement plate, which is displaced by actuating the first actuating element essentially in the longitudinal direction of the horizontal support within a mounting housing at the first longitudinal end of the horizontal support. Two, in particular identical, displacement parts, in particular displacement plates, are preferably provided, each displacement part having a guide slot through which the same guide pin can be inserted. The mounting housing can be mounted on the support element of the formwork, in particular via the guide bolt.

For positive guidance when adjusting the height of the horizontal support, it is advantageous if the mounting housing has an upper and/or a lower guide part, in particular an upper and/or a lower guide plate, for guiding an upper or lower edge of the displacement part with the guide slot. The displacement part is preferably arranged with a substantially precise fit between the upper and the lower guide part, so that the displacement part is only movable in the longitudinal direction of the horizontal support between the upper and the lower guide part.

If the mounting housing has a vertical slot that extends essentially perpendicular to the horizontal support and in which the guide pin is guided, the horizontal support is raised or lowered essentially perpendicular to the longitudinal axis of the horizontal support (based on its horizontal neutral position) without sideways movement.

In many applications it is also advantageous if a second adjusting device with a second actuating element is provided for adjusting an inclination of the horizontal beam relative to the supporting element of the formwork. In this version, the horizontal beam can be adjusted both in height and in inclination relative to the support element. With the help of the second adjusting device, the horizontal support can be brought into an inclined position starting from the neutral position. In a preferred embodiment, the maximum adjustment angle relative to the neutral position is at least +3° or -12°, preferably at least +10° or -20°. If the horizontal support is inclined downwards in the inclined position, the first, inner end of the horizontal support arranged further up than the second, outer end of the horizontal beam. If the support bracket is used for formwork, tipping is particularly suitable for stripping the formwork (i.e. for spacing the formwork elements from the concrete body). In this application, the horizontal beam can only be tilted downwards for stripping, whereby a formwork element arranged on the horizontal beam, in particular an outer formwork element and / or a floor formwork element, is detached from the concrete component produced with it, in particular a cornice cap. In addition, the second adjusting device can additionally be designed to tilt the horizontal support upwards starting from the essentially horizontal neutral position, so that the first, inner end of the horizontal support is arranged in the inclined position below the second, outer end of the horizontal support. This means that the horizontal beam can be adjusted before concreting, for example.

The second actuating element of the second adjusting device is preferably arranged on the second longitudinal end of the horizontal support facing away from the support element.

For stable load transfer, it is beneficial if a diagonal strut is provided to support the horizontal beam. With the help of the diagonal strut, the horizontal beam can be supported along its length from below.

In a preferred embodiment, the diagonal strut is connected to the mounting housing described above via a connecting lever, which is preferably shorter than the diagonal strut.

In one embodiment, the diagonal strut is supported in the mounted state of the support console via a thrust bearing on the support element of the formwork. In a first variant, the thrust bearing has a sliding surface which slides on an outside of the support element during the height adjustment of the horizontal support.

In a further embodiment, the thrust bearing at the inner end of the diagonal strut is formed by at least one roller, in particular a pair of rollers. When the height of the support console is adjusted, the roller rolls on the outside of the support element.

In order to facilitate the adjustment of the horizontal support, it is advantageous if the second adjusting device has a second force transmission element connected to the second actuating element, in particular a second spindle, and a spindle receptacle connected to the diagonal strut. In this embodiment, the second actuating element can be arranged on the second longitudinal end of the horizontal support facing away from the support element.

In a further embodiment, a spindle strut is provided as the diagonal strut, which has a middle part, in particular with a handle, on which a first and a second nut element are formed. The first nut element is preferably left-handed and the second nut element is right-handed. A first spindle element is screwed into the first nut element and a second spindle element is screwed into the second nut element. A left-handed and a right-handed spindle element is also preferably provided. If the middle part of the spindle strut is rotated, in particular by means of the handle, which is, for example, a pivot pin, the spindle elements approach one another or move away from one another, depending on the direction is rotated. In this version, the spindle strut can form the second adjusting device for adjusting the inclination of the horizontal support.

Depending on the application, the support device can have several support brackets, which are spaced apart from one another, particularly in the horizontal direction. The plurality of support brackets are preferably attached to a corresponding number of support elements.

For a height-adjustable connection of the horizontal beam to the support element, it is advantageous if the guide pin is mounted immovably on the support element of the formwork with respect to the height adjustment of the horizontal beam. In this version, the link guide is displaced relative to the stationary guide pin in order to adjust the height of the horizontal support. For a stable and secure connection between the horizontal support and the support element, it is advantageous if the support element has a first and a second support profile, between which a mounting housing, in particular in one of the embodiment variants described above, is arranged at the first longitudinal end of the horizontal support. The mounting housing is preferably arranged essentially between the first and the second support profile in such a way that the mounting housing can only be displaced upwards or downwards, but not to the side.

In order to enable a rough adjustment of the height (ie the vertical position) of the horizontal support, in a preferred embodiment the first and second support profiles have passage openings for the guide pin at corresponding longitudinal positions. Due to the reversibly detachable arrangement of the An initial height of the horizontal beam is determined by guide pins on one of the vertically spaced pairs of passage openings in the first and second support profiles. With the help of the first adjustment device, the height of the horizontal beam can be further changed starting from the initial height. A rough adjustment of the height is preferably achieved with the passage openings on the first and second support profile and a fine adjustment of the height of the horizontal support is achieved with the first adjustment device.

In a preferred application, a formwork with a support device is provided in one of the embodiment variants described above.

In a first preferred application, the formwork is designed as a cornice formwork. A cornice is the freely projecting edge area of a structure, such as a bridge. With the help of the cornice formwork, a cornice cap can be made. An outer formwork element, preferably also a floor formwork element, is preferably mounted on the horizontal support. The outer formwork element can preferably be fixed in different longitudinal positions along the horizontal support with the aid of an adjusting device.

In many applications, particularly in cornice formwork, it is advantageous if a platform support for a work platform is mounted below the horizontal support of the support device. The first adjustment device, in particular also the second adjustment device, can be operated from the work platform. Preferably, only a single work platform is mounted below the horizontal beam of the support device, in particular on the support element.

In a further preferred application, the horizontal support of the support device itself is designed as a stage support for a work platform. The work platform is therefore supported from below by the horizontal beam. In this embodiment, there is preferably no work platform provided below the horizontal beam.

For example, the support console can be mounted on a support frame for a single-sided formwork element or on a tunnel formwork element, for example on the curved outer formwork, of a tunnel formwork.

The disclosure further relates to a building with a concrete component, for example a cornice cap, and a formwork in one of the previously described embodiment variants. The formwork is (temporarily) connected to the concrete component.

As already mentioned above, a formwork, such as a cornice formwork, can have an outer formwork element and an inner formwork element, preferably also a floor formwork element. The outer formwork element and the inner formwork element, preferably also the floor formwork element, define a space in a formwork position that is filled with concrete in order to produce the desired concrete body, in particular a cornice cap. The inner formwork element is arranged on the side of the cornice, the outer formwork element on the side facing away from the cornice.

• ein Innenschalungselement,

• wobei das Außenschalungselement, vorzugsweise zudem das Bodenschalungselement, an der Stützkonsole und das Innenschalungselement an dem Tragelement befestigt ist.

In a preferred embodiment, the outer formwork element, preferably also the floor formwork element, is attached to the support console and the inner formwork element is attached to the support element of the support device. The inner formwork element is therefore connected to the support element independently of the support bracket. The inner formwork element therefore does not take part in the adjustment of the support console via the first and possibly the second adjusting device. This embodiment is advantageous for various reasons. The inner formwork element can be assembled and adjusted more easily, in particular because the inner formwork element can be attached to the support element in front of the floor formwork element. Stripping the formwork is also simplified because the outer formwork element and the bottom formwork element can be removed first before the inner formwork element is spaced from the concrete body. This creates more space for stripping the formwork on the inside. In addition, stripping can be safer be designed. This design can also be implemented independently of the height adjustment of the horizontal beam using the link guide. Accordingly, the present disclosure also relates to formwork, in particular cornice formwork, comprising:

• an external formwork element,
• an inner formwork element,
• preferably also a floor formwork element,
• a support console having a horizontal support, in particular in one of the embodiment variants described above,
• a support element, preferably a vertical support, the first longitudinal end of the horizontal support of the support console being attached to the support element,
• wherein the outer formwork element, preferably also the floor formwork element, is attached to the support console and the inner formwork element is attached to the support element.

The outer formwork element and the inner formwork element, preferably also the floor formwork element, can each have a formwork panel with a formwork surface facing concrete. The formwork panel can be made of wood or metal. Furthermore, at least one formwork support can be arranged on the back of the respective formwork panel facing away from the concrete.

In a preferred embodiment, the inner formwork element is attached to the support element of the support device via a holder, in particular movable between a shuttering position and a shuttering position. The holder is preferably mounted in an adjustable manner on the support element, so that the inner formwork element can be moved between the shuttering and shuttering positions by adjusting the holder, for example by linearly displacing the holder. Alternatively, the holder can be mounted immovably on the support element.

In a preferred embodiment, the holder has an adjusting element, for example an adjusting spindle or an adjusting screw, for moving the inner formwork element between the closing and closing positions.

In order to make operation easier, the adjusting element can be accessible on the side of the support element facing the inner formwork element. The adjusting element can thus be adjusted on the side of the inner formwork element.

In order to improve the detachment of the inner formwork element from the concrete body, the holder can have at least one elongated hole running obliquely (i.e. at an angle deviating from the horizontal) to the support element. In this embodiment, the holder with the inner formwork element can be moved between the shuttering and shuttering positions by sliding along the elongated hole, in particular by means of the adjusting element. When stripping the formwork, the holder can be guided diagonally downwards, for example, away from the concrete body using the elongated hole. This advantageously results in a positive guidance of the holder from the shuttering position to the shuttering position. In this version, the holder can have a bracket for the inner formwork element. The bracket can be connected to a bearing part on which the adjusting element, for example an adjusting screw with a nut, is mounted. The adjusting element can be connected to the bracket via a connecting part, for example via a connecting pin. The movement of the connecting part relative to the bearing part can be guided via another elongated hole.

In a further embodiment, the holder has a support bracket mounted on the support element, on which the inner formwork element is arranged. The support bracket can be arranged immovably, i.e. without adjustability, on the support element. In this embodiment, the inner formwork element can be placed on the support bracket.

Furthermore, it is favorable if the holder is fastened to the support element in a reversibly detachable manner, in particular via at least one securing bolt. The securing bolt can then be removed to remove the formwork. In a preferred embodiment, the securing bolt is in the elongated hole Bracket included.

Fig. 1 shows a formwork 1, which in the embodiment shown is attached as a cornice formwork to a cornice 2, ie to a preferably essentially horizontally extending, laterally freely cantilevered edge region of the building 3, here a bridge. For this purpose, the cornice formwork has a support device 4 with diagonal compression struts 5 and support elements, here vertical beams 6, which each are attached parallel and at horizontal distances from each other to the underside of the cornice 2. The support device 4 also has a work platform 7, which has a covering 8 with a horizontal work surface. At the rear longitudinal edge of the work platform 7, ie on the long side facing away from the cornice 2, a railing 9 with vertical railing supports 10 and horizontal protective elements 11 is arranged.

In the embodiment shown, the support device 4 also has a plurality of support brackets 12, each of which has a horizontal support 13 with a first longitudinal end 13A and a second longitudinal end 13B. The horizontal supports 13 are mounted on the vertical supports 6 with their first longitudinal ends 13A. The support brackets 12 also each have a diagonal strut 14 for supporting the horizontal support 13 on the underside.

The horizontal beams 13 carry a first formwork device 15 and a second formwork device 16, with which a cornice cap 17 can be produced on the cornice 2 in the embodiment shown. The first formwork device 15 has first formwork supports 18, which are arranged on the top sides of the horizontal supports 13, in particular essentially perpendicular thereto. The first formwork supports 18 carry a floor formwork element 19, here a formwork panel, with which a substantially horizontal formwork surface is formed in the embodiment shown. The second formwork device 16 has second formwork supports 20 and an outer formwork element 21, here a further formwork panel, with which a substantially vertical formwork surface is formed in the embodiment shown. The second formwork device 16 is positioned with the aid of essentially vertical cornice clamps 22, which are arranged on the horizontal supports 13 of the support consoles 12 in an adjustable manner in the horizontal direction. The cornice clamps 22 are supported at the back on the horizontal beams 13 with the help of diagonal support struts 22A. The support struts 22A are telescopic in such a way that the inclination of the cornice clamps 22 is adjustable. Thus, the cornice clamps 22 can be arranged not only in a vertical position, but also in a position inclined to the vertical.

How out Fig. 2 and Fig. 3 can be seen in detail, the support console 12 has a first adjusting device 23 with a first actuating element 24 for adjusting the height of the horizontal support 13 relative to the vertical support 6. The first actuating element 24 for adjusting the height of the horizontal support 13 is freely accessible at the second longitudinal end 13B of the horizontal support 13 facing away from the vertical support 6, so that simple adjustment from the work platform 7 is possible.

How out Fig. 4 As can be seen, the first adjusting device 23 has a first force transmission element 25, which is formed here by a first spindle 25A. By actuating the first actuating element 24, a force is exerted with the force transmission element 25 in the longitudinal direction of the horizontal support 13, ie in the direction of its pronounced longitudinal extent, which, as will be explained further later, is converted into the height adjustment of the horizontal support 13. The horizontal support 13 has an elongated hollow profile 26 in which the first spindle 25A is arranged. The first spindle 25A extends over more than 3/4 of the length of the horizontal support 13, from its outermost point in the horizontal direction to its innermost point.

In the embodiment shown, the first adjusting device 23 has a link guide part, hereinafter referred to as link guide 27, with which an adjustment essentially in the longitudinal direction of the horizontal support 13 is converted into the height adjustment of the horizontal support 13. The link guide 27 has a guide slot 28, which runs at an angle of essentially 45° to the longitudinal axis of the vertical support 6 (vertical in the assembled state). A guide pin 29 is mounted in the guide slot 28 and is mounted in a stationary manner on the vertical support 6 with respect to the height adjustment. The guide slot 28 is provided on a displacement part in the form of a displacement plate 30, which when adjusting the first spindle 26 essentially in the longitudinal direction of the horizontal support 13 within a mounting housing 31 at the first longitudinal end 13A of the horizontal support 13 is postponed. The mounting housing 31 has an upper guide part in the form of an upper guide plate 32A and a lower guide part in the form of a lower guide plate 32B, between which the displacement plate 30 is guided with a substantially precise fit on the top and bottom sides. In the embodiment shown, two identical displacement plates 30 are provided, which are guided on the same guide pin 29.

How out Fig. 5 As can be seen, the mounting housing 31 has a vertical slot 33 on each side (relative to the horizontal neutral position of the horizontal support), in which the guide bolt 29 of the link guide 27 is guided. With the help of the vertical slots 33, the up and down movement of the support consoles 12 is enabled during the height adjustment.

The vertical support 6 consists of a first support profile 6A and a second support profile 6B (cf. Fig. 2 ), which are arranged parallel and at a horizontal distance perpendicular to the horizontal support 13. Depending on the version, the first 6A and the second support profile 6B can each be a U-profile. A gap is formed between the first support profile 6A and the second support profile 6B, into which the mounting housing 31 is inserted at the first longitudinal end 13A of the horizontal support 13. The first support profile 6A and the second support profile 6B each have individual passage openings 34 at the same longitudinal positions, so that the guide pin 29 can optionally be arranged in different height positions. With the help of the pairs of passage openings 34, a rough adjustment of the height of the horizontal support 13 can be made. The first adjustment device 23 enables a fine adjustment of the height of the horizontal support 13. By actuating the first actuation element 24, the support console 12 moves upwards or downwards with an unchanged inclination of the horizontal support 13, depending on the direction of actuation. The diagonal strut 14 is supported on the vertical support 6 via a thrust bearing 35. In the execution of the Fig. 1 to 8 the thrust bearing 35 has sliding surfaces 35A, which can slide on an outside of the vertical support 6. The diagonal strut 14 has one compared to the diagonal strut shorter connecting lever 14A connected to the mounting housing 31.

The height adjustment of the horizontal support 13 is described below using the Figures 4 to 8 described.

Fig. 4 shows the horizontal support 13 in a starting position in which the guide pin 29 is arranged in the middle of the longitudinal slots 28 of the sliding plates 30. In order to raise the horizontal support 13, the first actuating element 24 is rotated with a tool in one direction of rotation. This rotational movement is taken over by the first spindle 25A, which is in threaded engagement with a first nut 25B at the end opposite the actuating element 24. This causes the first spindle 25A to be screwed further into the first nut 25B. This adjustment of the first spindle 25A in the longitudinal direction of the horizontal support 13 causes the displacement plates 30 to move to the side within the mounting housing 31, with the guide pin 29 being displaced relative to the displacement plates 30 along the guide slot 28. The displacement plates 30 rest on the inside of the mounting housing 31, so that the sideways movement of the displacement plates 30 is converted into the upward movement of the horizontal support 13 with the mounting housing 31 and the hollow profile. In the 5 and 6 the maximum elevation of the horizontal support 13 is shown, with the guide pin 29 being attached to the lower end of the guide slot 28.

The horizontal support 13 is lowered by rotating the actuating element 24 in the opposite direction. This further unscrews the inner end of the first spindle 25A from the nut 25B. The displacement plates 30A move inwards, the guide pin 29 moves upwards along the guide slot 28 and the horizontal support 13 is lowered accordingly. The maximum lowering of the horizontal beam is in the 7 and 8 shown.

As seen in the sectional views of the Fig. 4 , 6 and 8th As can be seen, inside the hollow profile of the horizontal support 13 there are two holding plates 25C, each with a passage opening for the First spindle 25A is provided to provide support for the first spindle 25A over its length.

Fig. 9 and Fig. 10 show an alternative embodiment variant in which the thrust bearing 35 is formed at the inner end of the diagonal strut 14 by a pair of rollers 35B. The pair of rollers 35B rolls on the outside of the vertical support 6 when the height of the support console 12 is adjusted.

How out Fig. 2 to 10 As can be seen, the support consoles 12 also each have a second adjusting device 36 with a second actuating element 37 for adjusting an inclination, ie an inclination to the horizontal, of the horizontal support 13. The horizontal support 13 can therefore be arranged not only in an exactly horizontal position, but also in a position inclined to the horizontal. Like the first actuating element 24 for the height adjustment, the second actuating element 37 for the inclination adjustment is also freely accessible at the second longitudinal end 13B of the horizontal carrier 13 facing away from the vertical carrier 6. A height adjustment and an inclination adjustment can thus be carried out independently of one another at the outer end of the horizontal support 13. The second adjusting device 36 has a second force transmission element 38 connected to the second actuating element 37, in the embodiment shown a second spindle 39, and a spindle receptacle 40 in the form of a second nut connected to the outer end of the diagonal strut 24. By rotating the second spindle 39 with the aid of the second actuating element 37, the spindle holder 40 moves inwards or outwards depending on the direction of rotation. This changes the inclination of the diagonal strut 14, which is articulated at the inner end to the connecting lever 14A and at the outer end to a spindle housing 41 which is mounted on the underside of the horizontal support 13. Inside the spindle housing 41, the second spindle 39 is accommodated, which can be shorter than the first spindle 25.

In Fig. 11 to 13 an alternative embodiment of the second adjusting device 36 is shown, in which the diagonal strut 14 is designed as a spindle strut. The spindle strut has a middle part 42C, which forms a first and a second nut element (one left-handed, the other right-handed) at the ends. A first spindle element 42A and a second spindle element 42B are screwed into these nut elements (also a left-handed and a right-handed spindle element). If the middle part 42C of the spindle strut is rotated by means of a handle 43, here a pivot pin, the spindle elements 42A, 42B approach one another or move away from one another, depending on the direction of rotation.

15A and 15B show in detail an embodiment variant in which a viewing window 31A is formed on the mounting housing 31, which provides a view of a marking 30A on the sliding plate 30. Depending on the position of the displacement plate 30, the marking 30A moves along the viewing window 31A. The extent of the height adjustment is thus signaled to the operator via the relative position of the marking 30A to the viewing window 31A on the mounting housing 31. Above the viewing window 31A, a scale 31B is provided, in which an absolute value of the height adjustment relative to the middle position is indicated. Advantageously, the height position can be preset without any measuring utensils. Furthermore, the height position can be read at any time.

How out Fig. 1A and Fig. 1B can be seen, the cornice formwork 1 also has an inner formwork element 60, which, however, is not reversibly and detachably mounted on the support console 12, but on the vertical support 6 of the support device 4.

Fig. 14A and Fig. 14B show a first embodiment of a holder 61, with which the inner formwork element 60 between the in Fig. 1A and Fig. 1B shown shuttering position and a shuttered position spaced from the cornice cap can be adjusted relative to the vertical support 6.

In the embodiment of Fig. 14A , 14B The first support profile 6A and the second support profile 6B have pairs spaced apart in the height direction on their mutually facing bottom surfaces Openings, here the through openings 34 for the locking pin 29, which are arranged aligned with through openings in the holder 61. With the help of securing bolts 63, the holder 61 is detachably held on the vertical support 6. The holder 61 also has an adjusting element 66, here an adjusting spindle 61A. To remove the formwork, the inner formwork element 60 is spaced from the concrete by actuating the adjusting element 66. In the embodiment of Fig. 14A and Fig. 14B the inner formwork element 60 is adjusted in the longitudinal direction of the horizontal beam 13. The securing bolts 63 are then removed and the inner formwork can be dismantled.

In the 14C, 14D and 14E A further embodiment of the holder 61 is shown, which in turn is mounted on the vertical support 6 via the securing bolts 63. In this embodiment, the holder 61 has a bracket 70 with at least one elongated hole 65 running obliquely to the vertical support 6, here with two parallel elongated holes 65, each running obliquely to the vertical support 6, in which at least one, here two, securing bolts 63 are arranged. The bracket 70 is connected to a bearing part 71 on which an adjusting element 66, here an adjusting screw with a nut, is mounted. The adjusting element 66 is connected to the bracket 71 via a connecting part 72, here a connecting pin. The movement of the connecting part 72 is guided via a further elongated hole 73. By means of the adjusting element 66, the inner formwork element 60 can be moved obliquely downwards from the shuttering position to the shuttering position. The actuation area of the adjusting element 66 is arranged on the same side as the inner formwork element 60 with respect to the vertical support 6.

In the Fig. 14F a further embodiment of the holder 61 is shown. In this embodiment, the holder 61 has a support bracket 67, which is mounted stationary or immovably on the vertical support 6 with the help of the securing bolts 63. The inner formwork element 60 is supported on the support bracket 67. A spacer 68, in particular made of wood, can be placed between the inner formwork element 60 and the vertical support 6. be arranged. The support bracket 67 is removed for stripping the formwork. To do this, the securing bolts 63, with which the support bracket 67 is attached to the vertical support 6, are removed. The inner formwork element 60 can then be removed.

Fig. 16 shows an embodiment of the formwork 1 as a tunnel formwork 44 with an inner formwork 45 and an outer formwork 46. With the tunnel formwork 44, a tunnel segment with an arcuate cross section can be produced. In this embodiment, the support bracket 12 is mounted on the outer formwork 46, which forms the support element here. The horizontal support 13 of the support console 12 is designed as a stage support for a work platform 47 with a (here horizontal) work surface for workers. A railing post 48 for attaching protective parts 49 is arranged at the second (outer) longitudinal ends 13B of the horizontal beam. With the tilt adjustment, the work surface can be aligned horizontally for the operating personnel. This is an advantage due to the different tumbling cross sections. Fig. 17 shows an embodiment of the formwork 1 as a single-sided formwork 50, which is supported with a support frame 51. In this embodiment, the horizontal support 13 of the support console 12 is also designed as a stage support on which a work platform 47 is arranged. The support console 12 is releasably mounted on the support frame 51, which forms the support element in this embodiment.

Fig. 18 shows a detailed view of the support console 12, which in the application shown supports the work platform 47 from below. The support console 12 is mounted on the vertical support 6. The support bracket 12 can also be attached to other supporting elements, such as the outer formwork of the tunnel formwork 44 ( Fig. 16 ) or the support frame 51 ( Fig. 17 ) to be assembled.
