Definitions

  • connection element which is designed such that it is suitable for fastening a clamp to an inner tube of a telescopic vertical tube and a telescoping vertical tube, which has an outer tube and an inner tube displaceable in the outer tube, with such a connection element.
  • Telescopic vertical tubes are used for setting up slab formwork, scaffolding or scaffolding.
  • Vertical pipes are known as a prop z. B, for formwork, as a scaffolding tube as part of a so-called modular scaffold (spatial structure) or as part of a Vertikalrahmend used in facade scaffolding, regardless of the purpose, these must be adjustable in height.
  • the props In scaffolding, it is often necessary to adapt the individual vertical tubes or thus formed vertical frame to the course of the substrate, for example, to an inclined floor or stairs.
  • the props must occupy a predetermined defined height. Therefore, the telescopic vertical tubes on an outer tube and an inner tube, which is displaceable for length and height adjustment in the outer tube and thus telescopic.
  • This height adjustment can be done by moving the inner tube in stages, for example by inserted in through holes pin.
  • the height adjustment can also be infinitely variable, for example, characterized in that the inner tube has an external thread which is screwed into a corresponding mating thread or nut, wherein the mating thread or the nut is supported against the outer tube.
  • the inner tube may be loosely inserted into the vertical tube and associated with other components, such as a thread root plate.
  • stiffeners are usually used to stabilize the same vertical parallel spaced vertical tubes.
  • these stiffeners may be, for example, simple struts or frame members. These stiffeners increase the buckling resistance of the vertical tubes. This is important when several vertical tubes are placed on top of each other. A vertical tube can stiffened carry more load.
  • a pipe coupling in scaffolding in addition to system stiffening elements in modular scaffoldings and facade scaffolding pieces of pipe used as stiffening elements, which are connected via so-called pipe couplings with the vertical pipe, a pipe coupling consists of a clamp which is placed around the corresponding pipe section and this jammed, It is a non-positive Connection,
  • the clamp is usually formed by two hinged half-shells, the free ends can be pressed together by means of screws or wedges.
  • the couplings described can be directly, usually articulated, attached to the pipe serving as a stiffener.
  • rotary joints in which two substantially identical clamps are hinged together at least in one axis, which is a clamp attached, for example, to the vertical tube and the other clamp on the pipe section used as a stiffener.
  • the displaceable inner tube which is usually designed as a spindle, carries stiffeners.
  • DE 20 2004 002 593 U1 discloses such a connection element with a disk-shaped connecting element rosette with a plurality of openings, which is intended to be mounted on a configured as a spindle inner tube of a scaffolding tube, wherein the openings are intended to receive wedge-like terminal heads, wherein the connecting element surrounds the spindle in a flange ,
  • an internal thread is provided on the inside of the connection element, which engages in the thread of the spindle.
  • the connection element is closed, that is, it must be on the spindle be screwed on.
  • it consists of two half-shells, which must be folded around the spindle, with an additional step for locking arises.
  • SGB's CUPLOK support system uses special mast feet mounted on the underside of a slidable spindle-shaped inner tube, with connections for attaching the stiffening elements. It must therefore be kept ready special components on the site, which must be used planned, since they can not be subsequently used after the construction of the scaffolding.
  • the CUPLOK system from SGB also uses "Bracing Cuppler", which is placed around the inner tube, ie the spindle, in the manner of a clamp. The inner diameter is adapted to the spindle and the connecting element is not designed for attachment to the outer tube.
  • connection element which allows the attachment of a stiffener on both the outer and inner tube of a vertical tube.
  • connection element or a telescopic vertical tube having the features of claim 1 or claim 8.
  • Advantageous embodiments are the subject of the dependent claims.
  • the connecting element according to the invention is designed so that it allows the attachment of a clamp to an inner tube - preferably spindle - a telescopic vertical tube. It thus serves to ensure that a clamp which does not fit directly to the inner tube, for example because of the larger diameter, can be fastened to the thinner inner tube of the vertical tube.
  • a clamp engages around a tube and clamps it, so that a positive and / or positive or non-positive connection between the clamp and pipe section forms.
  • the clamp here comprises the connection element according to the invention.
  • a telescopic vertical tube is understood here to mean that it has an outer tube and an inner tube which can be displaced therein, the inner tube being displaceable in different positions in steps or continuously.
  • the inner tube has an external thread and is then usually referred to as a spindle, while the inner ear can be used as a separate component, for.
  • Example be designed as a spindle with nut, the vertical tube comprises a guide, so that the outer tube can not buckle against the inner tube, so the two tubes extend substantially along the same axis.
  • a vertical tube having a smooth inner surface in which the inner tube / spindle is rotatably mounted so that different lengths of the vertical tubes can be adjusted.
  • the spindle is usually inserted only sufficiently loosely in the outer tube, so that the vertical tube can absorb only compressive forces in the axial direction.
  • the pressure forces are absorbed by a screwed onto the spindle nut, which in turn is supported against the opening of the outer tube.
  • the spindle and nut is designed so that even with the maximum unscrewing of the spindle, this is performed adequately in the outer tube.
  • the nut preferably has wings for turning without tools.
  • the spindle can be inserted at the upper or lower end of the vertical tube and thus form a head or foot spindle,
  • Such spindles preferably comprise a head or foot plate, a threaded tube and a spindle nut. These threaded spindles are plugged into modular scaffolding vertical posts or vertical tubes of a facade or scaffold.
  • the connecting element has an inner peripheral surface which is frictionally secured to an outer peripheral surface of the inner tube when the clamp is frictionally secured to the outer peripheral surface of the connecting element, not allowing the connecting element alone, that is without folded and fixed clamp, a fixture.
  • the attached to the inner tube connecting element can therefore sit even with little play on the tube or due to its elasticity under tension sit the inner tube and so at least temporarily attached.
  • This is understood to mean that the connection element alone, d. h, without fixed clamp, initially holds its position on the outer tube and in particular by hand in the axial direction displaceable or removable from the inner tube.
  • the actual attachment to the inner tube takes place only through the clamp when it has been tightened, that is non-positively attached to the outer peripheral surface of the connection element.
  • the connecting element is further configured such that its outer circumferential surface in the installed state has the same radial distance from the axis of the vertical tube as the outer peripheral surface of the outer tube.
  • This allows the same clamp, which is usually connected / connectable to the stiffener, to be selectively attached to the thicker outer tube or thinner inner tube with the interposed connector.
  • the stiffener or connecting means for the stiffeners therefore, no consideration must be made as to whether this stiffener is attached to an inner or outer tube. If the clamp is fastened to the inner tube, the connecting element according to the invention arrives as an intermediate piece for the insert without first being involved in planning.
  • the clamps on the outer pipe and the inner pipe may have the same orientation. This plays a role, for example, in stiffeners with not rotatable in all axes coupling elements or clamps.
  • connection element is designed as a sleeve and therefore inexpensive to manufacture as a simple tube profile.
  • the sleeve is designed with a lateral slot ("C-shaped profile") and can therefore also be made as a cutaway continuous profile.
  • the slot serves to enable the sleeve to be slid from the side onto the inner tube and not have to be pushed over the inner tube in the axial direction the slot is so wide that the connecting element can be pushed through the slot in the radial direction on the inner tube.
  • the slot is approximately as wide or slightly narrower than the widest diameter of the inner tube. For a spindle, the widest diameter is the outer circumference of the thread.
  • the sleeve is made of a material which is sufficiently elastic for the intended use, and the slot has a width smaller than the largest diameter of the inner tube.
  • a suitable material is plastic, preferably a thermoplastic or thermosetting plastic.
  • Such a sleeve can be easily attached and the relatively soft but sufficiently firm surface adapts to the thread. Slipping of the coupling is thus prevented and the sensitive thread of the spindle is not damaged. In this respect, a certain form-fitting can also arise; essentially, however, it is a non-positive connection,
  • one or more inwardly directed projections can be provided on the inside of the inner circumference of the sleeve, which can engage in the thread of the spindle and thus form a positive connection against slipping of the sleeve in the vertical direction. Simultaneously, by rotating the sleeve, a fine adjustment of the vertical position of the sleeve can be effected.
  • the one or more projections may also be formed as a thread, some threads or parts of a thread.
  • the elasticity of the sleeve can be effected by the material but also its shape.
  • inelastic sleeve parts may be resiliently interconnected, e.g. B. by a bridge.
  • the sleeve is made in one piece, in particular as a plastic injection molded part. It can also be designed as a cut extruded plastic or metal.
  • the slot has chamfers or Kantenabundungen, which facilitates on the inner and / or outer edge of the slot, the removal or removal of the sleeve.
  • the inner opposite flanks of the slot are tapered in the direction of the sleeve interior.
  • This orientation of the flank thus represents a kind of funnel shape, which facilitates the quick insertion of the sleeves by their guidance on a pipe.
  • the flanks can be arranged in particular in planes which lie in the sleeve axis. The sleeve thus has the shape of a circular profile from which a segment is cut out.
  • connection element is designed as a multi-part sleeve.
  • two half-shells can be applied by hand to the tube or two half shells are connected to each other via a hinge. It can therefore form at least two partial shells together the sleeve, wherein preferably the partial shells are connected to each other foldable, z. B. over hinges, joints or a bending connection.
  • the subshells are connected to each other via a narrow bendable web, wherein the web can be made of the same material as the subshells. It thus offers the possibility of the multi-part sleeve functional multi-part, but manufacturing technology in one piece particularly easy to manufacture.
  • a telescoping vertical tube is claimed with a clamp attached to the inner tube, wherein the clamp is fastened with the aid of the connecting element according to the invention to the inner tube and the clamp are part of a clutch, quick coupling, rotary coupling or stiffener with integrated clamp.
  • the clamp can serve to attach any component. It can also be part of it a coupling or quick coupling, for example, to attach a stiffening pipe or frame.
  • the clamp may also be part of a rotary coupling, are attached to the other components, for example, a stiffener.
  • the clamp can also be part of a stiffener with integrated clamp or coupling.
  • the vertical tube has a plurality of identical clamps, one of the clamps being fastened directly to the outer peripheral surface of the outer tube and another clamp, as described above, being fastened to the inner tube by means of the connection element according to the invention
  • additional simple, inexpensive and easy-to-use component can be attached either to the thicker outer tube or thinner inner tube or the thinner spindle.
  • the vertical tube is part of a scaffolding, z. B. as scaffolding tube or as the two vertical posts in a scaffolding frame.
  • a scaffolding frame two parallel vertical tubes in the lower and upper regions of the outer tube are connected to each other by horizontal beams to form a frame.
  • So-called modular scaffolds are preferably connected by means of prefabricated system components and have corresponding connection options.
  • This may, for example, be a system with vertical stem and wedge heads on the bars and diagonals for hanging in the plates.
  • this may be a system with prefabricated frames connected and stiffened by means of bars and diagonals.
  • the vertical tube can also for formwork support purposes, z. B. as a prop, be trained or be used.
  • connection plates 2a are shown on the outer tube 2, which are not essential to the invention.
  • a known in scaffolding clamp-type coupling 6a comprises the right outer tube 2 and is mounted on this non-positively.
  • the coupling 6a consists of two hingedly interconnected half shells, the free ends are pressed together by means of screws or wedges and thus pinch the tube 2.
  • the coupling 6a is used to attach stiffeners 7, here a tube, which is increasing the buckling strength connected to the left vertical tube 1 in a similar manner.
  • stiffeners 7, here a tube which is increasing the buckling strength connected to the left vertical tube 1 in a similar manner.
  • a further coupling 6b is attached to its circumference, which is structurally identical to the upper coupling 6a. However, this is not directly attached to the spindle 3, but on the connecting element 5 according to the invention, which therefore forms a kind of adapter or transition piece.
  • FIG. 1 shows a vertical tube 1 as a special foot, in the upper end of normal vertical tubes, ie those that are not telescopic, can be used, but the spindle-nut combination can also be used directly in such a normal vertical tube, the Clutch can be attached to this normal vertical tube without connecting element.
  • FIG. 2 shows the connection element 5 according to the invention in detail in the plan view.
  • the substantially C-shaped sleeve-like connecting element made of plastic was pushed from the right onto the spindle (not shown) and is latched onto the latter
  • the substantially circular tube profile is slotted on the left along the two mutually facing flanks 51
  • Flanks 51 tapers inwards and forms a kind of funnel 51.
  • the flanks 51 have chamfers 52.
  • the narrowest width D1 between the flanks 51 is smaller than the maximum diameter D2 of the inner tube or the spindle, which allows snap-fastening and temporary fastening
