Definitions

  • the invention relates to a transom-column connection for columns and transoms which are formed from concrete and at least one profile, the open chambers of the profile being largely filled with concrete and the outer surfaces of the flanges being exposed, i.e. are not covered with concrete.
  • Such a support, which on the flange outsides, i.e. has no concrete outside the profile contour lines is described, for example, in DE-A-28 29 864.
  • the chamber concrete is non-positively connected to the inner web sides of the steel profile in order to avoid detachment of the chamber concrete both at room temperature and at fire temperature.
  • Steel profile cross-section, concrete cross-section and reinforcement steel cross-section contribute proportionately according to their surface area and their temperature-dependent strength. In the event of a fire, the temperature rises and the load is continuously shifted from the steel section to the reinforced concrete section, primarily due to the softening of the flanges, which make up the majority of the steel section.
  • the applicant in LU-A-84 772 has proposed to arrange at least one further profile in the concrete that connects to the web of the main profile whose outer flanges are not covered with concrete. Since some of the profiles that make up this composite profile are attached in thermally protected zones a high load-bearing capacity is guaranteed under fire.
  • patent application LU-A-84 966 the applicant further described such a composite profile in which at least one flat iron connected to the web of the profile is arranged in the concrete.
  • the lugs can be attached to the flange of the support. But there is also the option of welding a sheet metal to the two opposite flange sides and attaching the lug to this sheet metal.
  • the lower flange side of the transom is placed on the collar on the structure (and possibly welded) while the two ends of the upper flange can also be welded to the support flange.
  • the so-called head plate lug connection the bolt end is provided with a head plate.
  • the lower flange (as well as one side of the head plate) comes to rest on the lug, while the head plate is screwed to the support flange near the upper transom flange.
  • longitudinal and transverse holes can be provided in the flange or in the head plate. The cavities required for the screwing work are also subsequently concreted.
  • articulated support connections can be made, as is common in conventional steel construction, which, however, constructions with composite beams and composite supports do not always bring the desired success. This is particularly the case if steel profile girders and supports are used for the composite construction, the flange outside of which are exposed, that is, are not covered with concrete.
  • transom-column connections have the disadvantage that, if used in the construction with composite steel profiles, they do not allow the largest possible prefabrication in the factory.
  • the advantages of the invention consist in the fact that the weld seam that may have to be made on the construction site between the pull tab and the support flange lies outside the transom and thus remains visible until the ceiling is concreted. Furthermore, the course of the moment in the bolt is favorable and is reduced by up to 50% and transferred to the support; Significantly smaller dimensions of the bar are therefore possible.
  • the achieved frame effect allows lateral (horizontal) forces to be absorbed and there is the option of dispensing with other stabilizing elements such as truss or reinforced concrete core.
  • a warm advantage is to be seen in the fact that the tension area is embedded in the concrete of the ceiling above the protected transom flange when the frame corner moment is negative.
  • a complete provisional assembly of the steel skeleton is possible according to the invention; the welding seams that may be required can be carried out in a second phase.
  • a support 1 is shown to which a latch 2 is connected.
  • the bolt and the support were manufactured in accordance with the measures described in DE-PS 28 29 864 and essentially consist of a steel profile 3, chamber concrete 4 and reinforcing steel 5, the reinforcing steel being fastened to the web 6 of the steel profile 3 (see FIG. 2) .
  • dowels 7 were welded onto the beam 6.
  • the adhesion of the ceiling concrete 8 is ensured by dowels 9 arranged on the upper flange of the bar 2.
  • the pull tab 10 which brings about the transom-support connection and the support plate 11 can be seen in FIG.
  • the support plate 11 has approximately the width of the support flange and is provided with two holes 12 for receiving the mounting bolts 13 (see Figure 4).
  • These holes 12 with the corresponding mounting bolts 13 are not indispensable, but allow a provisional assembly of the steel skeleton. The welding work can be carried out at a later time.
  • the dimensions of the bolts 13 are slightly below those of the holes 12.
  • the support plate 11 is welded all around to the support 1 by means of a fillet weld, except on the upper side, where the plate has been chamfered and there is a stronger sunken weld seam 15.
  • the countersunk seam allows the bar 2 to lie firmly and thus a balanced flow of the transverse forces from the bar to the support plate. Because this countersunk seam 15 is protected from direct heat radiation, this is the weld seam which in reality allows the support plate 11 to transmit transverse forces from the bar 2 to the support 1 in a warm state for a longer period of time.
  • the fire resistance of the unprotected support plate 11 can thus reach at least 90 minutes.
  • the pull tab 10 is advantageously welded to the locking flange in the factory (reference number 16).
  • the tab should be in the level of the crossbar.
  • the assembly weld seam 17 is carried out at a later time. In order to achieve an optimal flow of forces, this part of the pull tab is sharpened and is therefore connected to the support via a K-weld seam.
  • the mounting bolts 13 and the holes 12 are arranged according to a preferred embodiment of the invention in such a way that the tab also comes to lie in the plane of the support web.
  • FIG. 5 Another embodiment of a transom support connection is shown in FIG. 5.
  • the bolt 2 and the pull tab 10 are provided with a head plate 50 at the factory.
  • the lower flange of the bolt 2 and the underside of the head plate come to lie snugly on the support plate 11 while the head plate 50 is screwed to the support flange on both sides of the pull tab 10 (reference number 52). Since the screwing work can be carried out immediately in any weather, the recesses 12 / projections 13 are available in this embodiment.
  • the composite steel profile-chamber concrete is secured here by brackets 51 welded to the webs.
  • the flap will lie in a fire-protected area and as a result, together with the bars of the transom 2 and the support 1 protected by chamber concrete, a regular flow of tensile forces of the negative frame corner moment in the warm state is optimally guaranteed.
  • the tab can therefore continue to perform its load-bearing function if that of the support plate has weakened considerably, and so delay the collapse of the construction for up to 180 minutes.
