Definitions

  • the invention relates to a method for producing carriers with an open single or multiple web from a starting material with a full web, and to a thus produced carrier with an open web.
  • the straps were initially made from a solid material with a parallel belt, corresponding to the maximum load.
  • the beams were dimensioned for the place exposed to the greatest load, they were oversized along most of the beam and therefore extremely heavy and material-intensive.
  • this carrier can also be dimensioned along the entire length only according to the maximum utilization, whereby this carrier is also oversized along most of its length.
  • a method according to the introductory part of claim 1 (FR-A-2116356) was also known, the cutting line running obliquely to the longitudinal direction of the beam, so that after the beam halves were rotated by 180 ° and a mutual Moving the beam halves by half a period a beam of continuously changing web height is obtained. Even with this known method, however, only breakthroughs of the same size and division can be achieved.
  • the aim of the invention was to develop a method for the production of beams with a broken web, with the aid of a material with a full bridge, a beam without waste can be produced which has openings with a division and a suitable size corresponding to the load distribution .
  • the invention relates to a method for producing supports with an open single or multiple web from a support with a full web as a starting material.
  • the essence of the invention is that the carrier along its length - keeping an eye on the expected static load - into sections, or if only a characteristic static load is to be expected, the entire beam is considered as a single section, after which the web of the section (s) in two halves are cut symmetrically with respect to the point falling perpendicular to the center line along the length of the line, along a line of variable period consisting of straight lines or arcs, which gives breakthroughs with a dimension corresponding to the load, after which one half thus obtained is cut by
  • the center line is rotated through 180 °, the support halves are formed to form openings and, if there are several lines, the lines provided with openings are fastened to one another.
  • Period of the breakthroughs, dimension of the holes and shape of the holes, and of course resulting therefrom, the cutting line are determined taking into account the arrangement of the beam and the local loads.
  • both lines of the pairs are used in the same way, along a line composed of straight lines and / or arcs with a variable period - the openings with a dimension corresponding to the load result - cut in two and the resulting halves of the route result in closed openings and are attached to each other.
  • load-bearing support structures can be designed in wide scales. This enables beams with constant and variable heights, arched, straight beams and those with a broken format to be produced.
  • FIG. 1 shows a carrier section with a straight axis and full web, the web of which is cut in two with a variable period along a line 3, which is composed of straight lines and is symmetrical with respect to the point of symmetry o falling into the center line k of the carrier section the center line k is rotated.
  • the halves 2 are attached to one another or welded.
  • a girder with the girder of height h or a girder with the girder of height H or with an enlarged girder arises from the girder.
  • insert elements 5 are fastened or welded in between the web halves.
  • the web of the carrier is already fastened in the initial state, i.e. it is designed monolithically with the risers 1.
  • FIG. 7 represents a version of the carriers produced by the method according to the invention, in which the change (alternative arrangement) of the perforated and the full parts of the carrier section has a gradual and changing character on a small scale.
  • the alternative arrangement of the openwork and the full parts takes place in several large steps.
  • broken and full parts are arranged in a jump, changing in one step.
  • the change in the full and the perforated parts has a gradual, small-scale character; In the middle of the field there is a longer full part.
  • Such a design can be advantageous in the case of supports which are articulated on two supports and which are loaded in the center of the field with a single concentrated force.
  • FIG. 13 shows a carrier which is clamped at one end and is articulated at the other end and is evenly loaded.
  • FIG. 14 illustrates the moment image of the beam, taking into account that the beam - taking into account the characteristic static load - is divided into sections.
  • the carrier is divided into sections a, b and c. Subdivision into sections is not described in detail here since it does not affect the essence of the invention. Accordingly, the web of the girder is cut in a point-symmetrical manner along the line according to FIG. 15 to the point o falling on the center lines k a and k b . In this exemplary embodiment, only the upper half of the web is cut according to the sections, which - after it has been rotated about the center lines k a and k b - are placed on the lower part to form openings and fastened thereon. Likewise, the upper web parts rotated by 180 ° are attached to one another. ( Figure 16)
  • the web of the two sections is cut in two in the same way, but of course in accordance with the load, along a line with a variable period that creates openings with variable dimensions, after which the halves of the route obtained in this way are paired in such a way that the closed breakthroughs occur.
  • the carriers can be produced without waste, in such a way that the distances in both directions are the same length in relation to the center line.
  • the method according to the invention can be implemented quite advantageously by using optically controlled cutting torches with several torch heads, plasma cutters, etc.
  • the hollow girders can be produced much more economically than the previously used hollow girders with a uniform period without any particular additional work.
  • material savings of around 10 to 33% can be achieved.
  • the method according to the invention can be used not only with single-beam, but also with multi-beam beams, including U-beams, equally with beams of any complexity with a closed profile, even with a tubular or elliptical cross section, in this case the side parts of the tube or another curved cross section to be considered as a web.
