Definitions

  • the invention relates to a height-adjustable steel support for slab formwork and the like.
  • a lower tube piece carrying a foot plate in which an upper shaft part is telescopically slidably mounted, which has a row of holes arranged in its longitudinal direction and uniform hole division and by a plug bolt inserted through a hole in the row of holes is supported against the lower pipe section, wherein the steel support carries a device for gradually lowering the shaft part with respect to the lower pipe section, which has a locking bolt arranged in the area of the shaft part and limitedly pivotable about a pivot axis running perpendicular to the longitudinal axis of the support.
  • height-adjustable steel supports (ceiling sprouts) are usually used in the required number to absorb the load of formwork panels, reinforcement and concrete.
  • square timbers, truss girders or steel girders are placed on the heads of the steel supports, on which the actual formlining, which is usually made of standardized formwork panels or Depending on the surface quality of the ceiling to be achieved, it also consists of large-area formwork panels.
  • This construction support has a device for gradually lowering the shaft or upper pipe part with respect to the lower pipe section, which has a locking bolt arranged in the region of the shaft part and limitedly pivotable about a pivot axis running perpendicular to the longitudinal axis of the support.
  • the locking bolt is designed in the form of an eccentric disc, which engages the bottom plug pin of the shaft part and which can be locked in its respective position by a clamping screw. Clamping the eccentric disc by means of a clamping screw is not harmless from a safety point of view, because it carries the risk that if the clamping screw is tightened improperly, the steel support suddenly yields by an amount given by the hole division.
  • the object of the invention is therefore to provide a height-adjustable steel support that meets all safety requirements and enables a uniform lowering of the entire formwork structure down to a comfortable working height and thus a safe and material-friendly formwork dismantling.
  • the steel support mentioned at the outset is characterized according to the invention in that on the locking bar a hook part engaging under a first plug bolt inserted through a hole in the row of holes and at least one catchment and support surface for a second one inserted through the hole of the row of holes which initially follows upwards Plug bolt-carrying catch part are designed so that when the locking bolt is in a first stable swivel position, the first plug bolt is held in the hank part by locking the shank part against the end face of the lower pipe section or a threaded sleeve screwed onto it and when the shank part is in a second swivel position out of engagement with the first plug bolt standing hook part, is supported only on the catch and support surface of the catch part via the second plug pin and that the catch and support surface are curved in such a way mmt and is arranged with respect to the hook part in such a way that when the locking bolt is pivoted from its second into its first pivot position, the second connector bolt released from the catch and
  • the locking bar is in its first swivel position, in which its hook part is the lowest
  • the pin engages underneath and thus locks the shaft part against the lower pipe section forming the lower part of the steel support.
  • the locking bolt is now pivoted into its second pivoting position, which takes place, for example, by means of a few hammer blows or in an manner to be described, using an actuating element or tool.
  • the upward-facing catch and support surface of the catch part of the locking bolt moves under the second upper plug pin, while at the same time the hook part disengages from the lower first plug pin and releases it.
  • the entire formwork lowers until the second upper connector pin is caught by the catch and support surface of the catch part of the locking bolt swung in under it.
  • the lower connector pin released by the hook part is relieved; it can be pulled out and inserted into the next free hole in the row of holes in the shaft part.
  • the shaft part carrying the formwork is always supported by a plug bolt either on the hook part or the catch and support surface of the locking bolt, the shaft part can never be released from the locking bolt and can be pushed almost completely into the lower part under the load of the formwork.
  • the steel support therefore meets all safety requirements.
  • the hook part is arranged at the lower end and the collecting part with the support and collecting surface facing upwards at the upper end and the collecting and supporting surface has a convexly curved region arranged at the end which is designed in such a way that when the locking bolt is pivoted from the second into the first pivoting position of the shaft part, it can initially be temporarily raised via the second plug pin.
  • This slight lifting of the shaft part and thus the load when pivoting the locking bolt from the second to the first position ensures that an independent, unwanted pivoting or turning of the locking bolt is excluded under unfavorable conditions when the plug bolt hits the catch and support surface .
  • the locking bolt is fork-shaped with two arms encompassing the shaft part on both sides, each of which has a hook part on one end and a catch part on the other.
  • the two arms can be connected to one another by a crossbar which has at least one of the two pivot positions defining stop means.
  • the locking bolt In order to facilitate the actuation of the locking bolt and thus the step-by-step lowering device, it is expedient for the locking bolt to be provided with actuating means which permit its pivoting.
  • actuating means can preferably have an actuating pin arranged on the crossbar, which allows an extension rod or another corresponding tool to be attached.
  • the device for gradually lowering the shaft part on the steel support i.e. to arrange their lower pipe section firmly, i.e. to manufacture steel supports set up from the outset for gradual lowering.
  • the device for gradually lowering the shaft part is releasably attached to the steel support, so that existing steel supports can also be equipped with this device in a simple manner.
  • the device itself can expediently be designed in such a way that the locking bolt is pivotally mounted on a lower part, which is supported by the lower pipe section - optionally via the threaded sleeve.
  • the lower part can have a clamp-shaped holding part which surrounds the shaft part with play and which is supported axially, optionally via the threaded sleeve, against the lower pipe section.
  • the arrangement is expediently such that the holding part has at least one half-shell detachably connected to one another.
  • the steel support has a lower pipe section 1 forming the lower part, which carries a footplate 2 and is provided at the other end with an external thread 3, onto which a threaded sleeve 4 is screwed, which laterally carries two actuating brackets 5 allowing its rotation.
  • a row of holes extending over its length is formed, the holes 10 of which have the same spacing from one another with their axes in a common plane containing the longitudinal axis 110 of the shaft part, which means that the row of holes is formed with uniform hole division.
  • Each hole 10 is in turn formed by two coaxial, cylindrical bores in the opposite walls of the tube piece forming the shaft part 6. Through the individual holes 10, cylindrical plug bolts 11 can be inserted, each of which carries a handle 12 which extends approximately at right angles.
  • the steel support described so far is of conventional design.
  • the support length is set roughly by inserting a plug pin 11 into a corresponding hole 10 in the shaft part 6, the shaft part 6 being supported on the threaded sleeve 4 via this plug pin 10, which in turn enables the support length to be finely adjusted.
  • the steel support is now provided according to the invention with a detachably attached device which allows a gradual lowering of the shaft part 6 and thus the formwork 8, 9 with respect to the lower pipe section 1.
  • This device has a locking bolt 13, which is pivotably supported to a limited extent about a pivot axis indicated at 140 and extending at right angles to the longitudinal axis 11.
  • the locking bolt 13 is essentially fork-shaped (FIG. 7) with two arms 15 connected to one another by a cross piece 14, which grip around the shaft part 6 on both sides and each of which is designed in the manner of a double-armed lever.
  • each of the arms 15 is provided with a hook part 16 which, in the meadow shown in FIG. 2, is set up to engage under a lower or first plug pin inserted into a hole 10 in the row of holes, and thus the sheep part 6 is stationary lock against the threaded sleeve 4 and the lower pipe section 1.
  • each of the arms 15 is formed with a catch part 17, which carries an upward-pointing catch and support surface 18 for a second plug pin 11a which is pushed through the hole 10a (FIG. 8) of the row of holes which follows upwards.
  • the catch and support surface 18 has at the end a region 19 which rises slightly upwards to the top and is convex with respect to the pivot axis 14 and which is designed in such a way that when the locking bolt 13 is pivoted out of the second region to be explained in FIG Pivot position in the first pivot position shown in FIG. 2, the shaft part 6 is first raised slightly before the collecting and support surface 18 releases the plug bolt 10a and thus the shaft part 6.
  • the crossbar 14 is provided on its inside with two stops formed by corresponding bevels 20, 21 which can come to rest on the shaft part 6 and which define the two pivot positions of the locking bolt 13: namely one shown in FIGS. 1, 2 and 5 " first "pivot position and a" second "pivot position illustrated in FIGS. 4 and 6.
  • an actuating pin 22 is welded to the crossbar 14, which allows an extension tube or another suitable tool to be pushed on, in order to move the locking bar between the mentioned first and second pivot positions.
  • the locking bolt 13 is pivotally mounted on two parallel bearing arms 24 of a lower part 25 by means of two pivot pins 23 coaxial with the pivot axis 140, which in turn has a clamp-shaped holding part 26 rigidly connected to the bearing arms 24, which consists of two ends at 27 (FIG. 9) consists of half shells 28 which are connected to one another in an articulated manner by means of a hinge pin and which are releasably connected to one another by a clamping screw 30 carrying a wing nut 29.
  • the two half-shells 28 enclose the shaft part 6 with play and are axially supported on the lower pipe section 1 via the threaded sleeve 4.
  • the locking bolt 13 is in its first pivot position and the shaft part 6 is locked against the lower pipe section 1 in that the lower plug pin 11 is received in the hook part 16 of the locking bolt 13 and against the lower part 25 against the threaded sleeve 4 and the lower pipe section 1 is supported, the ceiling formwork 8, 9 is lowered in the following manner:
  • the threaded sleeve 4 is screwed back until the lower part 25 with the half-shells 28 sits directly on the end face of the lower pipe section 1.
  • the formlining 9 detaches itself from the finished ceiling by a corresponding amount.
  • the second connector pin 11 a has been inserted into the hole 10a (FIG. 1) of the hole part of the shaft part 6 that follows upwards.
  • the locking bolt 13 is now pivoted out of its first pivoting position according to FIG. 1 by hammer blows or an extension tube plugged onto the actuating pin 22, as is illustrated in FIGS. 3, 4.
  • the overlying catch and support surface 18 is inevitably pivoted in under the second connector pin 11, while at the same time the hook part 16 begins to release the lower connector pin 11.
  • Fig. 3 illustrates approximately the moment when the hook part 16 is just releasing the lower connector pin 11; As can be seen, the collecting and supporting surface 18 with its surface area 19 already protrudes below the second connector bolt 11a.
  • the released lower plug pin 11 is relieved; it is removed from its hole 10 and inserted into the hole 10b (FIG. 4) of the row of holes of the shaft part 6, which hole follows first.
  • the locking bolt 13 is now pivoted clockwise.
  • the plug pin 11 a initially runs onto the convex surface area 19, which is designed in such a way that the shaft part 6 is initially raised slightly.
  • This design of the catch and support surface 18 ensures that an independent pivoting or twisting of the locking bolt 13 upon impact of the plug bolt during the transition from the first pivot position according to FIG. 1 into the second pivot position according to FIG. 4 is excluded.
  • the hook part 16 is pivoted in between the two plug bolts 11, 1a in the manner which can basically be seen in FIG. 6, while at the same time the surface area 19 is pivoted out to an increasing extent under the plug bolt 11a. This is possible because the distance between the surface area 19 of the support and mounting surface 18 and the lower edge of the hook part 16 is smaller than the smallest distance between two adjacent connector bolts 11, 11 a.
  • the shaft part 6 with the formwork 8, 9 lying thereon can thus be safely lowered in small steps.
  • the shaft part 6 is pushed into the lower pipe section 1 unhindered by the holding part 26, because the two half-shells 28 enclose the shaft part 6 with a corresponding radial distance and do not hold on.
  • the lower part 25 is releasably placed on the threaded sleeve 4 and thus the lower pipe section 1 by means of the holding part 26.
  • the lower part 25 is rigidly connected to the lower pipe section 1 below the threaded sleeve 4.
  • steel supports which have no threaded sleeve 4, releasably or non-releasably with the device described for gradually lowering the shaft part 6 and thus the formwork 8, 9.
