Definitions

  • the invention relates to a support device for the construction sector, in particular for supporting a joist formwork, with an elongate, horizontal crossbeam and at least two support bodies arranged perpendicularly to the crossbeam, the support bodies being height-adjustable.
  • Such a support device is from DE 1 684 236 A known.
  • Vertical and horizontal formwork elements of a joist formwork lie on the crossbeam and are laterally supported by the support elements.
  • a disadvantage of such support devices is that they are comparatively bulky and complicated to handle. For example, such a support device must be supported on the ground by at least two screw supports, which takes up a lot of space on the construction site.
  • the possible uses of this support device are limited to the support of beam formwork due to its comparatively bulky geometry.
  • KR 100926750 B1 discloses a formwork system in which two longitudinal members connected by a plurality of cross members carry a U-shaped formwork. Longitudinal beams are fastened to the longitudinal beams, on which in turn height-adjustable support bodies are built.
  • the DE 1049076 B shows a hanging formwork frame, which is supported on end-side bearing claws by crossbeams carried by props.
  • the invention is therefore based on the object of providing a support device of the type mentioned at the outset which avoids the aforementioned disadvantages.
  • the cross member is designed to be variable in length.
  • the entire width of the support device can be optimally adapted to a beam to be formed by adjusting the length of the crossbeam.
  • the support device according to the invention is therefore more compact and easier to handle.
  • the support bodies are advantageously arranged at the ends of the cross member, as a result of which the support device is even more compact, since the cross member protrudes as little as possible relative to the support body.
  • the support device according to the invention can be supported using only one screw support or another construction support and thus takes up less space on the construction site.
  • the crossbeam can be extended or retracted telescopically, as a result of which a stable length adjustment is possible.
  • the cross member comprises at least two coaxially arranged cross member segments.
  • a threaded rod which is arranged inside the cross-beam segments and interacts with at least one sliding nut fixed on one of the cross-beam segments is preferably provided for the stepless length adjustment of the cross-beam.
  • they can Cross member segments are fixed relative to one another by means of a frictional connection, for example by means of a laterally acting adjusting screw or a clamp, the length being adjusted by hand.
  • a stepped fixing with the help of safety bolts can also be provided.
  • the cross member segments are detachably connected to one another.
  • a side support is arranged on at least one of the support bodies, which extends in a direction perpendicular to a longitudinal direction or longitudinal center axis of the cross member and perpendicular to a longitudinal direction or longitudinal center axis of the support body.
  • the side member forms a vertical support surface that runs in a plane perpendicular to the longitudinal direction or longitudinal center axis of the cross member.
  • the length of the side support is preferably at least 40 cm, preferably at least 60 cm.
  • the vertical support surface has a length of at least 40 cm, preferably at least 60 cm, and a width of at least 2 cm, preferably at least 4 cm.
  • the area of the vertical support surface is advantageously at least 80 cm 2 , preferably at least 240 cm 2 .
  • Side support and support body can be designed in one piece.
  • the side support is fixed to one end of the support body.
  • the side support advantageously comprises an L profile rail, a T profile rail, a U profile rail and/or a square tube, which forms the vertical support surface. This ensures the necessary rigidity of the side carrier so that it can optimally absorb lateral forces.
  • the side member forms a horizontal support surface which runs in a plane parallel to the longitudinal direction or longitudinal center axis of the cross member.
  • the side supports can also be used for support from below.
  • the support device can also be used, for example, to support a blind box without the aid of squared timber.
  • the horizontal support surface has a length of at least 40 cm, preferably at least 60 cm, and a width of at least 2 cm, preferably at least 4 cm.
  • the area of the horizontal support surface is preferably at least 80 cm 2 , preferably at least 240 cm 2 .
  • the side supports comprise square tubes, with the vertical support surface and the horizontal support surface be formed from two sides of the square tube.
  • at least one side support can be formed by a U or L profile rail, with the vertical and horizontal support surfaces being formed by two sides of the U profile rail or the two legs of the L profile rail. This ensures the necessary rigidity of the side beams, which would otherwise sag when absorbing the lateral forces of a formwork element.
  • the support bodies are guided in and/or on the cross member in a height-adjustable manner.
  • tubular guide elements enclosing the support bodies along their circumference are arranged on the cross member.
  • the inner contour is preferably adapted to the outer contour of the circumference of the support body or parts of the support body, so that the support bodies are guided in the guide elements in a form-fitting manner. This stabilizes the supporting body against laterally acting forces without the need for additional support struts.
  • tubular also includes non-round tube shapes (e.g. square tubes).
  • the upper edges of the guide elements preferably end with an upper support surface of the cross member or the cross member segment, so that the support bodies can be lowered mostly or completely below the upper support surface, so that the side support arranged thereon rests on the upper support surface of the cross member or the cross member segment.
  • the cross support can be positioned as close as possible to at least one of the side supports.
  • Such a configuration of the support device is particularly stable.
  • due to the greater height variability it is also possible to form relatively small beams.
  • the support bodies can be removed, if necessary together with the side supports, from the cross member or from the guide elements.
  • the support device can support a ceiling with the uppermost support surface of the cross beam, which is formed by the upper support surface of the outer cross beam segment, while the support body and side beam support an edge formwork of a floor covering to be cast above the ceiling.
  • the side support is advantageously provided with openings through which a formwork element lying against the vertical and/or the horizontal support surface can be fixed to the side support by means of screws or other connecting means. This facilitates the quick production of a stable formwork.
  • two parallel support bodies are fixed to each side member.
  • the two support bodies arranged on a side member are arranged in such a way that their longitudinal center axes run in a plane perpendicular to the longitudinal center axis of the cross member.
  • the support bodies are preferably fixed to the guide elements receiving them by removable locking bolts, the longitudinal center axes of the locking bolts running parallel to the side supports.
  • both supporting bodies can be fixed by a common locking bolt.
  • the support bodies and the guide elements receiving them have corresponding bores.
  • the cross member has an adapter element for connecting external screw supports or other building supports that do not belong to the invention.
  • the support device can thus be connected to a prop in a non-positive and/or positive manner.
  • the adapter element has a thread for producing a screw connection. This leads to an easily manufacturable and particularly stable connection between the support device and the prop. Screw supports or other building supports are not part of the invention.
  • At least one of the side supports has a receiving element for receiving a fall protection or a part thereof.
  • the receiving element is preferably arranged in the form of a tube on the side of the side support facing away from the vertical support surface.
  • the support device includes a laser for aligning the support device and/or the formwork elements.
  • the laser preferably provides a laser beam running parallel to the vertical support surface and parallel to the horizontal support surface.
  • the laser is preferably arranged on or in a side support.
  • a bulging of a vertical formwork element can thus be checked by measuring the distance between the formwork element and the laser beam over the length of the formwork element.
  • two supporting devices can also be aligned with one another, for example by a fixed supporting device providing a laser beam and a further supporting device being aligned with it.
  • side supports designed as a square tube have end caps on both sides, with the laser being arranged in one of the end caps.
  • the side support has a bearing element which is designed in particular in the form of an L profile rail for receiving a formwork element that can be inserted from above and supports the formwork board from below and laterally.
  • Bearing element and side support can also be designed in one piece.
  • the support device according to the invention is thus a multifunctional construction aid or tool for construction.
  • Figures 1 to 7 show various embodiments of a support device 2 according to the invention for the construction sector with an elongate, horizontal crossbeam 4 and four pairs of height-adjustable, elongate support bodies 6 arranged at the ends and perpendicular to the crossbeam 4.
  • the crossbeam 4 can be extended or retracted telescopically and is therefore variable in length.
  • the cross member 4 comprises two coaxially arranged cross member segments 4a, 4b in the form of square tubes.
  • the individual cross member segments 4a, 4b are thus designed to be stable against torsion about a longitudinal central axis A of the cross member 4.
  • a threaded rod 8 arranged coaxially to the cross member segments 4a, 4b is used for continuous length adjustment of the cross member 4.
