Definitions

  • the invention relates to a connecting device with a clamping bracket for formwork panels which have edge webs projecting at their edges at right angles to the formlining, which are encompassed by the clamping bracket in the use position, the clamping bracket being pivotable about an axis parallel to one of the edge webs into a release position and into a use position is and in the use position with a free bracket arm facing away from the pivot bearing on a parallel to the second edge web rod or the like.
  • a comparable connecting device is known from US Pat. No. 3,550,898.
  • the pivotable clamp bracket is formed in two parts, the free bracket arm relative to the. pivoting bracket arm must be slidably guided and withdrawn into a clamping position. The retraction takes place by means of a wedge, which passes through elongated slots on the two bracket parts belonging together.
  • the free arm. is designed like a hook and overlaps a rod or bolt in Position of use.
  • the object is therefore to create a connecting device of the type mentioned at the outset, with which an alignment of the formwork panels to be connected is made possible at the same time. A separate, possibly lost wedge should be avoided.
  • the connecting device of the type mentioned is characterized in that the clamping bracket in the position of use at least partially positively engages around the surfaces of the edge webs facing away from one another and that an extension piece which can be displaced approximately in the direction of the bracket end is provided for bracing the free bracket arm, which clamps under the rod after moving. Alignment of the formwork is also made possible by the positive connection when bracing or an aligned formwork panel is fixed in this position.
  • the sliding extension piece makes a separate wedge unnecessary.
  • Alignment of the formwork panels to be connected in alignment with one another can be achieved particularly well and safely if the free edges of the edge webs bear against the inside of the bracket in the use position. By tightening and fixing the clamp, any slight dislocations of the edge webs can still be eliminated.
  • the extension piece can preferably be arranged on a projection of the free bracket arm, which can be swiveled past the rod and is at a distance from the rod in the use position.
  • the bow arm can be pivoted conveniently past the rod into its position of use or, after the extension piece has been pulled back, can be brought back into the release position and in the use position, the fixing and tensioning can then be carried out in a simple manner by pushing out the extension piece.
  • the displaceable extension piece with its upper side facing the rod, runs obliquely to its direction of displacement and the underneath rod side, the inclination increasing counter to the direction of displacement.
  • a tensioning effect can be achieved on the basis of the aforementioned inclination.
  • the release can be promoted later.
  • extension piece is displaceable on a support running approximately parallel to the underside of the rod and is designed as a wedge.
  • the fastening and clamping wedge - in addition to the guide on its underside facing away from the rod - or the like by means of a cross pin. be captively guided in a long slot.
  • the clamping bracket can be mounted so that it cannot be lost on the, in particular, permanently installed pivot axis, so that the entire fastening device is and remains connected to the respective formwork panel in an advantageous manner and to a certain extent the formwork is integrated.
  • a particularly favorable power transmission results if the free bracket arm with the extension piece between the edge web and the anchoring rod can be pivoted into its position of use. If the extension piece is then inserted and wedged between the free bracket arm and the rod, the desired pressure results on the edge web to be held.
  • the extension piece can have at its end facing away from the fastening end a protrusion protruding from the guide and the bracket arm for the attack of a tool, in particular a hammer. This not only favors the turning of the extension piece into its position of use but also the loosening, which can then be struck or pulled against the underside of this projection.
  • the inner contour of the clamping bracket can largely correspond to the outer contour of the two adjoining edge webs, the free bracket arm expediently having a projection directed into the interior of the bracket as a stop against the rod-side edge web.
  • the bow arm does not necessarily lie over its entire length, so that certain dimensional differences, tolerances and clamping paths can be compensated for and the end of the bow arm can be brought into contact with the corresponding edge web with certainty, since the aforementioned projection is expediently at the end of the Arm is provided.
  • the two edge webs on their upper surfaces facing away from their contact surfaces can run obliquely in cross-section from the formlining to their free edges and together form approximately a trapezoid and the bracket opening can accordingly be substantially trapezoidal.
  • the bearing eye of the pivot bearing of the clamping bracket can be designed as an eccentric and, in the open position, have a clear distance approximately twice the eccentricity from the adjacent edge web and be pressed against the edge web with the inside of the bow in the closed position.
  • the rod for anchoring the clamping bracket in its position of use can have an underside which is flat in cross section for the attachment of the extension, preferably as a square tube or the like. be formed, the cross section of its underside can be oriented approximately parallel to the sliding direction of the extension piece.
  • the sliding direction of the extension piece can be at a less acute angle to a perpendicular to the formlining than the free bracket arm and its inside that can be placed on the edge web.
  • pivot axis for the bracket and preferably the fastening rod run between webs of the formwork panel arranged at right angles to the connecting edge webs and / or anchored to these webs can be, so that there is no need for special housings or bearings, but stiffening webs of the formwork panels can be used to anchor the entire fastening device.
  • the combination A mirror-symmetrical arrangement and design of the swivel axes and rods with the possibility of also being able to dismantle the clamping bracket due to a lockable interruption of its passage opening for the swivel axis, despite its captivity, allows a rod that forms the swivel axis in one application case as a fastening rod for the other to use slidable extension piece and to pivotally attach the clamp to the rod previously used to anchor the extension piece.
  • clamps and formwork panels can be combined in almost any shape and it is not necessary to pay strict attention when connecting the formwork panels that a swivel axis and a fastening rod come to rest on the connection area on the one side.
  • a generally designated 1 connecting device for formwork panels 2, which have edge webs 4 projecting at their edges at right angles to the formlining 3, comprises in particular a clamping bracket 5 which, in the position of use shown with solid lines, the two edge webs 4 of formwork panels to be connected in alignment 2 embraces.
  • the clamping bracket 5 can be pivoted about an axis 6 parallel to the edge web 4 adjacent to it into a release position shown in dash-dotted lines and vice versa into the use position.
  • the clamping bracket 5 with its free bracket arm 7 facing away from the pivot bearing and the pivot axis 6 can be fastened to a rod 8 running parallel to the second edge web in a manner to be described and can be tensioned such that the two adjoining edge webs 4 are compressed in the manner shown will.
  • the clamping bracket 5 In order to hold the two formwork panels 2 together in an aligned position and, if necessary, to align them somewhat when bracing, the clamping bracket 5 in the position of use grips the surfaces 9 of the edge webs 4 facing away from one another, at least in regions, in a form-fitting manner. Furthermore, in this position of use, for a good alignment, the free edges 4a of the edge webs 4 rest on the corresponding inside of the frame.
  • an extension piece 10 is provided which is displaceable approximately in the direction of the free bracket end and which, after being displaced, engages under the rod 8 - as shown in the drawing - in a clamping manner. It can be seen from FIGS. 1 u. 2 clearly shows that in this position of the extension piece 10, pivoting back of the bracket 5 is blocked, that is to say is not possible.
  • the extension piece 10 is arranged on a projection 11 on the outside of the free bracket arm 7, which projection 11 can be pivoted past the rod 8 and is also at a distance from the rod 8 in the use position, which the extension piece 10 bridges.
  • the free bracket arm 7 can be swiveled into its use position between the edge web 4 and the anchoring rod 8, i.e. it is not pivoted over the side of the rod 8 facing away from the edge web 4 and hung there.
  • the displaceable extension piece 10 extends with its upper side 10a facing the rod 8 obliquely to its direction of displacement and guidance, this inclination increasing against the direction in which the extension piece 10 is displaced to reach the locking position shown in the figure. This results after a first contact of this upper side 10a with the corresponding lower side 8a of the rod 8 in the further one Displacement of the extension piece 10 in the desired manner a jamming and pressing the bracket 5 against both edge webs 4th
  • the extension piece 10 is displaceable on a support 12, which is shown in dashed lines and runs approximately parallel to the underside 8a of the rod, and is designed practically as a wedge with regard to the inclination of the top 10a.
  • the extension piece by means of a cross pin 13 can also be captive or the like in an elongated slot 14 of a flange or a groove wall. be guided on the outside of the bracket, as can be clearly seen in the exemplary embodiment.
  • the extension piece 10 has, at its end facing away from the fastening end, a projection 15 of its own that protrudes from the guide 12 and the bracket arm 7 or the projection 11 for the attack of a tool, e.g. a hammer.
  • This tool can either be used to fix this extension piece 10 in its position of use or to loosen it when the projection 15 is acted upon in the opposite direction. In practice, this results in an extension piece 10, which can be operated and acts like a push and pull bolt, but additionally also has the wedge effect already described.
  • the inner contour of the clamping bracket 5 largely corresponds to the outer contour of the two adjoining edge webs 4, although in the exemplary embodiment the free bracket arm 7 near its free end has a stop projection 16 directed into the interior of the bracket as a stop against the rod-side edge web.
  • the rest of Top 9 of this edge web 4 thus remains free, so that dimensional differences and tolerances do not have a negative effect, but rather the most widely spaced bracket areas come into contact with the top sides 9 of the edge webs 4 and produce the desired tensioning and connection with the best possible lever arms.
  • the two edge webs 4 run obliquely in cross-section on their upper sides 9 facing away from their contact surfaces from the formlining 2 to the free edges 4a and together form approximately a trapezoid; accordingly, the bow opening is also substantially trapezoidal.
  • the bracket 5 can be pivoted into its position of use even when the edge webs 4 are still somewhat spaced and can already bring the two edge webs 4 closer to one another and also align them.
  • the bearing eye 18 of the pivot bearing 19 is designed as an eccentric and has an approximately in the open position of the bracket 5 shown in phantom twice the eccentricity of the clear distance from the adjacent edge web 4, while in the closed position it is pressed against the edge web 4 with the inside of the bracket.
  • the rod 8 has for a good contact of the extension piece 10 a cross-sectionally flat underside 8a and is designed in the exemplary embodiment as a square tube, the cross section of its underside being oriented approximately parallel to the sliding direction of the extension piece 10. It can be seen from the orientation of the elongated slot 14 and the guide support 12 that the sliding direction of the extension piece 10 at a less acute angle to a perpendicular to the formlining 3 than the free bracket arm 7 and its inner side which can be placed on the edge web 4 lies. This not only allows the clamp arm 7 to be clamped against the edge web 4 acted upon by it, but also, in the desired position of use, results in a locking of the bracket 5 against unwanted swinging open.
  • the pivot axis 6 for the bracket 5 and also the fastening rod 8 can run in an advantageous and expedient manner between webs 20 of the respective formwork panel 2 arranged at right angles to the edge webs 4 to be connected and can be anchored to these webs 20. Overall, this results in a captive fastening device, wherein, of course, with relatively large distances between the webs 20 on an axis 6, a plurality of brackets 5 can also be located at a distance from one another.
  • this fastening device 1 is extremely simple, because after the two formwork panels 2 have been put together, only the bracket or brackets 5 have to be pivoted into the closed position and anchored by moving the extension piece 10 in order to achieve a connection of the two formwork panels 2 with high forces. Opening this device and thus stripping it is just as easy.
  • FIGS. 2 to 5 An exemplary embodiment modified in particular with regard to the clamping bracket 5 but also the fastening rod 8 is shown in FIGS. 2 to 5. Despite the proposed changes and modifications, the parts corresponding to the previously described exemplary embodiment are given the same reference numbers.
  • the clamping bracket 5 has a through opening 19a for its pivot axis 6 as pivot bearing 19, the edge profile of which has an interruption 21 which can be at least partially closed and has a length which corresponds to the cross section of the pivot axis 6. If the interruption 21 is thus opened, the clamping bracket 5 can be removed from the pivot axis 6 by moving it with its interruption 21 transversely to the course of the pivot axis 6.
  • the through opening 19a for the pivot axis 6 is a in the use position of the clamping bracket 5 transverse to the formlining 3, in the exemplary embodiment approximately at right angles to the formwork 3 from this elongated perforation and the interruption 21 of the edge of this elongated hole is near the end of this elongated hole facing away from the formwork 3 . 2 and 3 that the interruption is still arranged in the region of the longitudinal wall of the elongated hole and not approximately directly at its end, on the side facing away from the actual clamping bracket.
  • the clamping bracket can be easily moved away from the rear of the formwork panel 2 after it has been swung open, the pivot axis 6 then being released by the interruption 21.
  • the closure for the interruption 21 is formed by a pin 23 which can be lowered against a restoring force or a restoring spring 22.
  • a spring-loaded clip could also bridge the interruption, similar to an eyelet on a jewelry clasp, or a wall area resiliently extending transversely to the interruption could be provided, similarly to a snap hook.
  • a pin 23 which projects into the interruption 21 and can be pushed back out of it is sufficient.
  • the pivot axis 6 and the fastening rod 8 to be gripped by the displaceable extension or locking piece 10 are arranged at the same height and at a corresponding distance relative to the edge webs 4 of the formwork panels 2 to be connected. They have a matching cross section, which is circular in the exemplary embodiment, so that the pivot axis 6 and the rod 8 of two formwork panels connected to the clamping bracket 5 are arranged mirror-symmetrically to a plane running through the contact joint of the two formwork panels between their edge webs 4.
  • clamping bracket 5 can be dismantled by the above-described openable interruption 21 of its elongated hole in spite of a generally captive holder, pivot axis 6 and fastening rod 8 can be exchanged with one another to a certain extent. While in the embodiment according to FIG. 1, when assembling the formwork panels, care must always be taken to ensure that a swivel axis and a fastening rod come to rest on the joint to be connected on the one side, this embodiment no longer needs to be taken into account will.
  • Fig. 4 it can be seen that pivot axes 6 and / or rods 8 are provided along all four edge webs 4 of a rectangular formwork panel 2 each with the same distance.
  • a formwork panel can also be fastened to a formwork wall from vertical formwork panels 2 with its longer edges, which, on the other hand, is rotated by 90 ° so that its longer side comes to rest on the shorter sides of the former formwork panels.
  • a connection to a clamping bracket 5 can then also be carried out at this point.
  • FIG. 4 also shows that the pivot axes 6 and rods 8 are each arranged between stiffening ribs 20 of the formwork panel 2 and possibly even pass through transversely to their course and that the parallel to such stiffening ribs 20 and parallel to the shorter edges of a formwork panel 2 extending rods 8 and pivot axes 6 have at least one support 24, in the exemplary embodiment three such supports 24 each with respect to the edge web 4.
  • a support 24 with respect to a stiffening rib 20 would also be possible, however, as shown in FIG. 4, to be made correspondingly longer.
  • a formwork panel 2 which, for the connection to a neighboring formwork panel at any edge and with any height offset, additionally has stiffening rods and axles on which easy-to-use and easily lockable and anchored clamping brackets 5 act, which in the exemplary embodiment according to FIGS Figures 2 and 3 can also be implemented despite their captive bracket, so that the assembly of the formwork panels is facilitated.
