Definitions

  • the invention relates to a clamp for connecting in one plane side-by-side formwork panels according to the preamble of Claim 1.
  • Such a bracket is from DE-U-88 14 208 and EP-B1-0 369 197 known and has especially known for the simplicity of the Operation with effective creation of the desired one Proven clamping force.
  • An eccentric is used as the actuating element provided with an operating lever whose axis of rotation at the same time can also be moved at right angles to the formlining to make it rotatable is. If this eccentric is rotated, it causes its adjustment A corresponding adjustment at the same time as the swivel and swivel bearings of the two adjustment legs that are in the area of this turning and Pivot bearing can be detected by the eccentric.
  • the pivoting the adjustment leg away from the formlining at the same time the pivoting of the jaws against the one to be connected Edge profiles. This represents a very easy to use bracket represents.
  • DE-A-38 23 763 in turn shows a bracket of another type, in which a tensioning or operating lever is in the tensioning position protruding from the bracket and the panel is avoided.
  • two jaws connected by a single joint provided that move away from each other starting from the joint and are attacked by a pressure bar in this area, which receives the clamping legs in corresponding recesses.
  • This Pressure bar is adjustable by a parallel to the swivel axis Wedge forcibly moved and should thereby open the jaws or close. So are as an actuating or adjusting element two interacting and against each other during their operation rubbing parts necessary, namely the wedge and on the other hand the pressure bar.
  • the clamping jaws a shape suitable for their interaction with the pressure beam and the wedge must have a double-T cross-section and thus have interacting guides. Manufacture and assembly of these Due to these requirements, brackets are to be regarded as complex.
  • DE-U-80 09 045 describes a device for connecting other formwork panels arranged side by side are known, namely a bolt that penetrates the edge webs of two formwork panels and presses against each other by a tensile force applied to it.
  • This Traction can either be by using a on the bolt through a Cross pin mounted eccentric or with the help of a bolt a wedge arranged through it or with the help a thread on the bolt are applied.
  • bracket it’s not a swivel, the adjoining edge profiles compressing clamping jaws available.
  • a wedge is a commonly used in formwork technology Tools for applying clamping or clamping forces, so that very easy operability is achieved. Because the wedge is on Attack points of adjustment legs of the two jaws attacks, the forces emanating from him when striking targeted and largely evenly transferred to both jaws be, even if the clear distance between the jaws themselves to Detection of edge profiles consisting of hollow profiles is very large should be. In addition, a wedge shows very well whether it is struck or not, that is, the clamping position control yourself in a simple way. The assembly is also very simply because a simple hammer blow is enough to close it the bracket to start and perform. The same goes for for releasing the clip.
  • the points of attack for the designed as an actuating element wedge on the pivot bearing ends of the adjusting elements facing away from the two clamping jaws arranged and in particular at a matching point common attack point are provided. So the wedge serving as an actuating element does not have several different ones Act on and press attack points, but the wedge force is applied in one place and therefore to both Transfer actuation points of the two jaws, resulting in a largely uniform pivoting of both jaws leads.
  • the abutment area for the wedge does not have to be opposite a line connecting the two swivel bearings of the jaws at an angle be arranged, as is the case with the clip according to DE-42 36 070 A1 due to the large distance between the operating points and in this direction decreasing width of the wedge is required.
  • the wedge can displace a single part at a certain point and thereby two adjustment legs away from the formwork and thereby the jaws against the edge profiles to be connected swivel.
  • the clamping force can be chosen more or less arbitrarily.
  • too much clamping force cannot be generated because an eccentric is not rotated with a corresponding lever arm, which lever arm possibly even to exert a great force could still be extended.
  • the clamping force is rather more or less precisely by the wedge and its helix angle given.
  • the game in the connection area of the two Adjustment leg allows their mutual minor Pivoting on arcs while the connecting element itself adjusted more or less at right angles to the formlining becomes when the wedge attacks it more and more.
  • connecting element as Connecting bolt is formed. This is a simple part on which the wedge can also grip well.
  • the cross section of the swivel bearings of the clamping jaws hollow or U-shaped carrier can be the abutment for the wedge carry. Since this carrier is required for the swivel bearing, is also the accommodation of a corresponding abutment easily possible for the counter wedge surface.
  • the cross-section which is approximately U-shaped, can have the two U-legs on the side facing the formwork panel connecting crossbar and this crossbar can be the abutment form or carry.
  • This crossbar has the additional Advantage, as a stop on the edge profiles to be connected To be available and at correspondingly smoother and level Training to align these edge profiles when they are braced to serve. In addition, it stabilizes the entire bracket and serves as an abutment or supports the abutment for the counter wedge surface.
  • Another embodiment of the invention of very substantial and advantageous meaning can be that the wedge in the Swivel plane around a perpendicular to this swivel plane imaginary axis is curved, the inside of the curvature the or the actuation points of the adjustment legs.
  • the distance from the center of curvature can then be Outside of the wedge on the pivot bearings and the Attack abutments.
  • the outer curvature of the wedge is expediently continuously continuous arcuate, especially circular arc. So one leads Adjust the wedge to smoothly slide along the corresponding guides, preferably the two pivot bearings and the abutment.
  • the wedge can be on its side facing away from the formlining in particular as a narrow side wedge surface a stop or have a head start, which is a displacement of the Wedge limited in the release movement so that the wedge on the clip is also held in the release position.
  • the Wedge held captive on the bracket and the user must don't put a wedge into one when attaching the clamp Bring home position because this wedge is the home position from the start.
  • the release movement of the wedge can be done with the as Interacting cross-bolt Projection be limited so that the wedge both Swivel bearings also overlap in the release position.
  • This wedge curvature generally has that considerable advantage that the absolute length of the wedge is relative is large, but still the overall dimension of the wedge from its broad to its narrow side can be small, so on a formwork and the edge webs to be connected it does not survive to the side or only insignificantly. Consequently is also the accessibility of the wedge itself, for example in Angular ranges of the formwork, when it is loaded with a hammer much better than that of a normal straight one Wedge.
  • the wedge can be on the side of the point of attack facing the release position based on part of his adjustable length a steep climb or a faster increase in its width and then a transition have a flatter rise, the transition from that steeper in the flatter rise at the point of the wedge can be arranged when they touch the or the Actuate the jaws shortly before or in the first Touching contact with the edge profiles or there in particular provided beads are.
  • the length of the curved wedge and the radius of curvature of the serving as a wedge surface as well as that of the Wedge-bridged distances of the swivel bearings can be be chosen so that the protruding part of the loosened wedge with its end face arranged transversely to the wedge surfaces is arranged approximately parallel to the formlining.
  • connection bracket for formwork panels with edge webs or edge profiles that are on existing ones
  • Formwork panels can be used without any problems and the has a great advantage that the closure force does not shrink is possible. It can be installed very easily and the user can immediately tell from the position of the wedge whether and when the clip is securely closed.
  • the Operation is very simple in that one or more Hammer blows to both close and open the Brackets are sufficient.
  • a bracket denoted as a whole by 1 is used for connection of formwork panels arranged side by side in one plane on mutually facing edges, expediently on all Edges surrounding edge profiles 2, in the exemplary embodiment Have hollow profiles, these in Figures 1 and 3 Hollow sections and the formwork skins connected to them 3 are shown in broken lines.
  • the bracket 1 has two against each other Longitudinal surfaces 2a facing away from one another Edge profiles 2 swiveling and compressing them Jaws 4 and an actuator to be described for this pivoting of the jaws 4.
  • the two Clamping jaws 4 each have their own Clamping point 4a opposite end at an angle, in Embodiment an approximately right or slightly larger Angle, standing adjustment leg 5, the Adjustment leg 5 of the two jaws 4 towards each other are directed.
  • Both jaws 4 are approximately in the corner area Transition to their adjustment legs 5 on a common one Carrier 6 pivotally mounted.
  • the trained as joints Swivel bearing 7 can be clearly seen in all figures. In front in Fig.
  • the ends of the adjustment legs 5 are connected to each other and with play swivel and point for this connection is a connecting element, in the exemplary embodiment a connecting bolt running transversely to the swivel plane 10 on who is the common point of attack for the wedge 9 forms.
  • a connecting bolt running transversely to the swivel plane 10 on who is the common point of attack for the wedge 9 forms.
  • abutment 12 for the formwork 3 facing mating wedge surface 9b of the wedge 9 which abutment 12 is the wedge 9 when driving or inserting supports so that its increasing width the Attack point, that is, the connecting bolt in the exemplary embodiment 10 displaced in the manner already described and emotional.
  • the distance between the abutment 12 and the The point of attack of the wedge 9 is thus by this insertion the wedge 9 can be enlarged, that is, in a very simple manner is the displacement of the wedge 9 in a pivoting of the Adjustment leg 5 and thus the jaws 4 implemented.
  • the abutment 12 has the advantage of always the same Support for the wedge 9 and wear to record due to the displacement of the wedge 9.
  • Cross-section hollow or U-shaped carrier 6 also carries this abutment 12 for the wedge 9, which can be seen in FIGS and 3 can see well.
  • the cross-section is approximately U-shaped Carrier 6 has on the side facing the formwork panel 3 a cross piece 6b and 6b connecting the two U-legs this crossbar 6b, which could itself form the abutment, carries this abutment 12 in the embodiment.
  • the thickness this abutment 12 can be chosen so that the Wedge 9 finds favorable investment conditions.
  • the wedge 9 in this way at the various points can apply and exert its wedge effect without one to cause misshapen bracket construction and to allow the Connecting bolt 10 in the manner already described near the Connection line of the two pivot bearings 7 arranged is, the wedge 9 is in the pivot plane about a perpendicular to imaginary axis lying at this pivoting plane, wherein the inside of this curvature as a wedge surface 9a on the as Connecting bolt 10 designed the point of attack Adjustment leg 5 rests and attacks.
  • the wedge 9 is on the side facing away from the formlining 3 a wedge surface 9a formed as a narrow side Stop or projection 13, the displacement of the wedge 9th limited in the release movement so that the wedge 9 on the Clip 1 is also held in the release position as you would clearly recognizable in Fig.1.
