Definitions

  • Scaffolds are known in numerous embodiments. So it is from the area the formwork for ceilings at a higher height (also slab formwork tables known), for example, known as stiffening cross-ties to be provided with the clamping claws which grip in the longitudinal grooves of the upright be attached to the relevant post. This type of attachment is not positive against forces in the longitudinal direction of the post. On the For example, it is known in the field of facade scaffolding, posts with plate-like, to provide welded cross-overhangs to which crossbars are attached can be. This type of attachment presupposes the presence of the Cross overhangs ahead, which are laboriously welded to the uprights have to.
  • the invention has for its object a framework of the aforementioned Art to create that in combination with high stability and resilience with particularly rational manufacturability.
  • a scaffold with the features of the preamble of claim 1 is from GB-A-2 262 562 known.
  • GB-A-2 262 562 and also DE 36 41 349 A show scaffolding in which there is no positive connection Connection between upright and traverse in the longitudinal direction of the upright is provided.
  • WO 83/03868 shows a scaffold in which the connection between the upright and the crossbar also in the longitudinal direction of the post is form-fitting.
  • the positive connection is achieved by other means than in the present invention.
  • the scaffold according to the invention has a comprehensive, form-fitting definition of the crossbar in question on the post in question, without a cross projection would be provided with effort.
  • the form-fitting Specification also leads in particular in the longitudinal direction of the upright in question to the fact that the trusses are also highly resilient in the vertical direction, without a Take security risk.
  • the term "traverse” is also an arrangement of two or more horizontal struts one above the other, which are connected by connecting struts are interconnected, includes; such arrangements are usually called frames that act as stiffening cross connections can be installed between stands.
  • the form-fitting determination of forces in the longitudinal direction of the concerned Standing is due to the engagement of a protruding element in an opening formed, the protruding element protruding at the relevant end of the truss and the opening is formed on the relevant post or vice versa.
  • the former of these two options is particularly preferred because - looking at the entire scaffolding - more numerous means of intervention on the Stand than at the end of the truss and because of the openings in the stand are particularly easy to manufacture.
  • a longitudinal row of protruding elements or of openings is preferred provided along at least part of the post to a truss connection to be able to make at a selectable point in height.
  • the protruding elements or openings are spaced apart by a grid are provided; you can also provide cheaply that there are openings acts that also for the setting of two telescopically adjustable Upright parts have a function.
  • the projecting element or an element having the opening is preferably Can be moved back and forth in a direction that is essentially the longitudinal direction of the truss equivalent. Because of this measure, one can take the Traverse particularly problematic between two cross to be connected Bring upright, e.g. the two protruding elements on the two Truss ends are retracted so that the truss shortened with something Length fits straight between the two uprights. Then you can e.g. Extend the two extensions in the longitudinal direction of the truss and into the insert suitable openings in the two uprights.
  • the engaging part described in the last paragraph is essentially Can be moved back and forth in the longitudinal direction of the truss.
  • the same applies here Aspects, especially with regard to the collectibility of the relevant Traverse between two uprights to be connected, as they are related in the foregoing with the protruding element or with the opening Element have been described.
  • a bolt is arranged, which extends in the longitudinal direction the crossbar in question extends and is rotatable about its longitudinal axis and has a bolt head which is narrower than in a first transverse direction. in a second transverse direction so that the bolt head in a first rotational position can be introduced into the longitudinal recess and against in a second rotational position Pulling out in the longitudinal direction of the truss is fixed. Because of this training is the creation of the form-fitting definition Forces in directions perpendicular to the longitudinal direction of the post in question particularly easy.
  • the projecting element or the opening is formed in the end region of the engagement part. Because of this training, you can manipulate the Engagement part, the favorable displacement of the protruding element or the opening having element and the engaging part in the longitudinal direction of the truss accomplish and also the positive determination against forces manage all three spatial directions. Alternatively, it is possible the projecting element or opening assigned to the end of the truss away from the bolt and not in the bolt integrate.
  • a cross element is preferably assigned to the engagement part, with which the Engagement part displaceable in its longitudinal direction and rotatable about its longitudinal axis is. This cross member thus allows easy manipulation of the engagement part.
  • the bolt preferably has and is an elongated through opening a wedge element penetrating the through opening is provided by the movement of the bolt head in the undercut longitudinal recess can be clamped.
  • the bolt is preferably in the state without Wedge force application rotatable about its longitudinal axis by means of the wedge element.
  • the wedge element thus fulfills a double function, in that the bolt first is rotated about its axis without generating a wedge force and then by means of Wedge force is pulled in the direction of the relevant post.
  • Training can be added as a third function, that one by means of of the wedge element can move the bolt back and forth in the longitudinal direction.
  • a fourth function can be added that one by longitudinal displacement of the bolt by means of the wedge element at the same time that on the bolt provided projection element in engagement with the desired opening of the stand can bring.
  • the post in question is using Steel sheet hollow profile built.
  • Such uprights can be Manufacture cheaper than aluminum and are good Cross-sectional design and good material utilization are not essential heavier than aluminum stands.
  • the post in question preferably has at least one part its length has a substantially square cross section with four undercut longitudinal recesses.
  • the post in question preferably has at least two parts, which are telescopically adjustable relative to each other. In this way you can adjust different post lengths.
  • conventional components may also be present, such as Head plate, foot section, spindle height adjustment device for Fine adjustment.
  • the inner upright part preferably has one square cross section, which is particularly good too an outer upright part with a substantially square cross section and four undercut longitudinal recesses.
  • the crossmember in question preferably has at each end of the crossbar a truss head that is cast or forged Workpiece is and that of the definition of the relevant traverse contains the agent in question.
  • the scaffold according to the invention comes in numerous technical fields into consideration.
  • First is the construction area, where one in particular Slab formwork, especially those at considerable heights, can erect (which is often called formwork table).
  • Another one Fields are the work platforms, especially in considerable amounts (the often called load towers).
