Definitions

  • the invention relates to a clamp connection according to the preamble of claim 1.
  • a clamp connection is for example known for attaching crossbars to spars, in which a clamping part is screwed onto the pipe end a U-shaped recess for receiving the to be fastened Has tube.
  • the recess as such is through a slidable and adjustable in length plate lockable.
  • GB-A-1 250 607 describes a corresponding clamp connection, two spaced apart Screwed plates at the end of a crossbar, for example or welded on.
  • the one provided in these plates Slot for receiving a scaffold frame element can be closed with a wedge.
  • Clamp connections of this type are particularly useful in scaffolding required to a large extent to the frame elements, deck platforms, Posts, struts and similar components Connect and disconnect safely and quickly to be able to, especially with prefabricated components existing scaffolding.
  • connection point for the clamp connection is relatively arbitrary is and only ensures its secure attachment must be the crossbars and console pieces with one always the same, adapted to the clamp connection Cross section executed.
  • the invention has set itself the task of such To design clamp connections so that they consist of a few components persist, are cheap to manufacture and highly stressed, load-bearing welds can be dispensed with.
  • the form-fitting connection of the respective component on a crossbar or A console piece is the one with low operating force executable frictional locking of the Clamping piece in the predetermined by the positive connection Position secured so that a secure clamp connection is achievable.
  • the one resting on the crossbar or the console piece Area of the wall of the recess is best shaped so that he is on the crossbar or the console piece touches approximately flat, because then the surface pressure is small and deformations are excluded can be.
  • a locking device is provided is, with the help of the clamping piece in at least one Closed and an open position with respect to the Recess is noticeable. With appropriate training the locking device are also any intermediate positions possible.
  • the clamping piece can be designed in such a way that it is parallel to the associated profile bar Profile piece is formed; the clamping piece is advantageous in the direction of its longitudinal axis on a as Provide a suitable slot with a slot on the clamping surface, that of a bolt that can be screwed onto the profile rod Locking device is enforced.
  • the clamping piece is stationary on the profile piece and captively axially movable as well as in one any position fixable.
  • the clamp connection is particularly handy if the Bolt is designed as a threaded bolt and the clamping piece using a handle nut on the bolt is clampable; it is understood that other controls are also conceivable, such as a toggle lever operation.
  • the parallelism be guaranteed by the clamping piece and profile rod, for example, by between the web and the profile bar a spacer is provided, such as one on the Clamp or nut attached to the profile bar thereby simultaneously extending the nut thread serves for the threaded bolt.
  • Console piece clampable pressure surface of the clamping piece follows the cross-sectional shape of the crossbar so that together with the wall of the recess the clamped Cross section all around and the danger of one Is subject to deformation.
  • a particularly good storage of the clamping piece is achieved one if the profile bar as a rectangular hollow profile and the clamping piece is designed as a U-profile and the Straps of the U-profile on the side walls of the profile bar issue.
  • a covering platform a mostly diagonal longitudinal or Cross bracing, a longitudinal or transverse railing or intermediate rail of the railing or another Similar component with a cross bar or be connected to a bracket on a stand.
  • these components have the same cross section in their profile bars is sufficient for all clamp connections a single version of the used few components and the recess on the profile bars.
  • FIG here A typical scaffolding is shown in FIG here is provided with a chassis. It consists of some recurring with such scaffolding Components. Lateral, multi-part frame elements 1 consist of vertical stands 11 and horizontal, the crossbars 12 connecting the uprights 12 which can also be used here as ladder rungs and in welded to the stands 11 in a correspondingly narrow division are. They are therefore well suited for connection of the frame element 1 with the other components of the scaffolding. On the stands 11 can short Console pieces may be provided, especially when connections of other components required in places where a crossbar 12 is not available, for example if cross braces are connected Need to become. The following, generally on crossbars 12 related statements also apply in the same sense for such, not taken into account in the drawing Console pieces.
  • Rubber platforms 2 attached of which the upper rubber platform 2a has a passage 21 which has a flap 22 (Fig. 7) can be closed, and of transverse and longitudinal rims 23 and 24 is limited.
  • longitudinal struts 41 of a cross bracing, if necessary Bracing 4 provided together with the Covering platforms 2 give the scaffolding the necessary rigidity.
  • the crossbars 12 are expedient as the stand 11 from circular cylindrical tubes; other profiles are but conceivable and can to the clamp connection according to the invention can also be easily connected, which is then to be designed slightly differently.
  • all other components are made of profile bars P composed of a cross section of a rectangular hollow profile, such as in particular 4 and 5 can be read.
  • profile bars too P can instead use a differently shaped one Cross section; however, this points independently of the respective component, advantageously the same dimensions so that uniform sized Clamp connections are possible and only a few different ones Components are needed.
  • the area of a clamp connection according to the invention is 8 and 9 can be seen in detail.
  • the profile bar P is closed (on both sides) with a stopper S.
  • a recess PA is in one End area PF of the profile bar P and follows with a Axis of symmetry PQ transverse to the longitudinal axis PL of the profile bar P and in the direction of the longitudinal axis 121 (FIG. 4) of the cross bar 12 in its upper region PA1 the profile of the cross bar 12, so that there the recess PA rests flat on the associated cross bar 12.
  • a Slot PA2 opens the recess PA towards the bottom PU of the profile rod P and is dimensioned so that the profile rod P with only slight play in the direction its longitudinal axis PL rests on the crossbar 12.
  • Insertion bevels PE make it easier to overlay the Crossbar 12.
  • a bolt 51 of a locking device 5 is on the Profile rod P with a thread 51a stationary, but screwable provided; a welded to the profile rod P.
  • Spacer PD extends the nut thread of the thread 51a and ensures that a clamping piece 6th there is such a distance from the profile bar P, that it is roughly parallel when the associated one Crossbar 12 placed in the recess PA and from that Clamping piece 6 is overlaid.
  • One fixed to the bolt 51 Handle 52 makes operation easier.
  • the clamping piece 6 is designed as a U-profile, the Belts 61 on the side walls PS of the associated profile bar P, including this with easy play, while the connecting web 62 on the spacer PD strikes.
  • the web 62 is in the direction of Longitudinal axis 64 of the clamping piece 6 an elongated hole 62a (Fig. 5) broken through, which is penetrated by the bolt 51 is and the clamping piece 6 limited longitudinally makes.
  • the arrangement is such that (in Fig. 8) the clamping piece 6 can be moved to the right is that the slot PA2 is no longer covered.
  • the 8 corresponds to the position of the clamping piece 6 shown the final in the assembled state of the Fig. 4.
  • the clamping piece 6 then loads the cross bar 12 a pressure surface 63 in the two belts 61, the Shape adapted to the cross section of the cross bar 12 so is that a flat system is guaranteed and the Surface pressure is bearable.
