Definitions

  • the invention relates to a support device according to the preamble of claim 1.
  • the invention relates to a formwork with such a support device.
  • Such a formwork device is known, with which a cornice cap in particular can be manufactured on a bridge.
  • 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.
  • 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.
  • 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.
  • 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.
  • the formwork removal process is carried out.
  • 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.
  • the shields usually hold on so strongly Cornice cap so that the formwork holder does not initially fall.
  • 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.
  • 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
  • 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.
  • 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.
  • 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.
  • the shields adhere so strongly to the cornice cap that has just been concreted that the formwork holder is not lowered.
  • 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.
  • 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.
  • 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.
  • 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.
  • JP 2009 287286 A 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.
  • 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.
  • the location and direction information refers to the installed use state of the support console on the support element.
  • the first adjusting device has a link guide with a guide slot for a guide bolt that runs obliquely to the horizontal support.
  • 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.
  • 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.
  • the link guide 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.
  • 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.
  • the guide pin (related to the height adjustment) is mounted stationary, ie immovably, on the support element of the formwork.
  • the link guide 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.
  • 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.
  • 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.
  • 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.
  • 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.

  • 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.
  • a linear drive for example a cylinder-piston drive or a servomotor, can be provided as the first force transmission element.
  • 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.
  • 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.
  • 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.
  • 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 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a second spindle 39 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.
  • 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.
  • the height position can be preset without any measuring utensils. Furthermore, the height position can be read at any time.
  • 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.
  • 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.
  • the holder 61 also has an adjusting element 66, here an adjusting spindle 61A.
  • the inner formwork element 60 is spaced from the concrete by actuating the adjusting element 66.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
