Definitions

  • the invention relates to a method for manufacturing a steel beam, the steel beam serving together with concrete as a bearing composite structure for various slab systems, and in the method, the base plate, web parts and top plate of the beam are cut from a plate material, the above-mentioned parts are assembled in such a manner that between the parts, a space is formed for concrete fed through openings in the web part, and the parts are welded together. Further, the invention relates to a steel beam.
  • the invention relates to a beam, on which the bearing structures of a building, such as hollow-core slabs, composite slabs, shell slabs and cast-in-situ, can be supported, During seam grouting or other concreting, the beam is filled with concrete, and after the concrete has hardened, the beam serves as a composite structure. Beams of this type are today quite well known in the field of element structures. Examples of solutions known in the field are those described in Finnish publications 85745 and 92089 .
  • the use of a composite structure provides a steel beam that is lighter than the earlier ones and the beam can be used at longer bearings than the earlier beams.
  • the method of the invention is characterized in that the web parts are cut to a curved shape according to pre-cambering, that side supports determining the position of the web parts and centre supports determining the location of the top plate are fastened to the base plate at regular intervals in the longitudinal direction of the beam, that a force is directed to the base plate that forces the base plate to the curvature determined by the web parts, whereby the side supports determine the position of the web parts and the centre supports determine the curvature of the top plate to be set in place.
  • the means of the invention is, in turn, characterized in that the web parts have been cut to a curved shape according to pre-cambering, side supports determining the position of the web parts and centre supports determining the location of the top plate are fastened to the base plate at regular intervals in the longitudinal direction of the beam, that the base plate has been forced to the curvature defined by the web parts, whereby the side supports have been arranged to determine the position of the web parts and the centre supports have been arranged to determine the curvature of the top plate.
  • the advantage of the invention over the prior art is above all the fact that the manufacture of the beam is essentially simpler than before, whereby the costs are substantially lower.
  • the implementation of the method of the invention is also simple in practice, whereby the introduction and use of the invention are advantageous.
  • the method of the invention is also very flexible, because the invention can be applied in an advantageous manner to the manufacture of very different beams.
  • Figures 1 to 5 show the method of the invention in a set of figures shown in steps.
  • reference numeral 1 marks the base plate of the beam
  • reference numeral 2 marks the web parts
  • reference numeral 3 marks the top plate.
  • Figures 1 to 5 only show one web plate. However, a finished beam has two web plates, as shown in Figure 6 , for instance.
  • the base plate 1 of the beam is first placed on a platform, as shown in Figure 1 .
  • side supports 4 determining the position of the web parts 2, i.e. the web plates and centre supports 5 determining the location of the top plate are fastened to the base plate at regular intervals in the longitudinal direction.
  • the side supports 4 and centre supports 5 are clearly shown in Figure 6 .
  • the fastening of the side supports 4 and centre supports 5 to the base plate is shown generally in Figure 2 .
  • the top plate 3 can also be set in place on the centre supports 5, as shown in Figure 2 .
  • the web plates 2 are placed on the side supports 4.
  • the web plates 2 are cut to a curved shape according to the pre-cambering of the beam.
  • the curved shape of the web plate is shown exaggerated.
  • Setting the web plates 2 on the base plate 1 is shown in Figure 3 .
  • openings 6 are also made to the web plates 2, through which concrete can be fed inside the beam.
  • a force is directed to the base plate that forces the base plate 1 to the curvature determined by the web plates 2, whereby the side supports 4 determine the position of the web plates 2 and, because the centre supports move with the base plate to the position according to the curvature of the web plates, the centre supports 5 determine the curvature of the top plate 3.
  • the above-mentioned force is marked with arrows F in Figure 4 .
  • the base plate 1, web plates 2 and top plate 3 are fastened together by welding to obtain the beam shown in Figure 5 .
  • the beam can also be equipped with end plates to close the ends of the beam.
  • the end plates are not shown in Figures 1 to 5 .
  • the end plates are fastened to the beam by welding.
  • the end plates are shown by way of example in Figure 7 and marked with reference numeral 7.
  • the method of the invention described above is particularly advantageous in that the manufacture of the beam is done without expensive jigs that were earlier used in the manufacture of beams.
  • the above-mentioned side supports 4 are formed in such a manner that they comprise a part to be fastened to the base plate and having a first end 4a arranged to determine the location of the low edge of the web plate and a second end 4b arranged to determine the location of the top edge of the web plate.
  • the side supports 4 can in principle be made in any shape.
  • a particularly advantageous solution is one in which the part to be fastened to the base plate is substantially L-shaped and the free ends 4a, 4b of its branches are arranged to form the ends determining the locations of the edges of the web plate 2.
  • the outer surface of one branch is arranged to serve as the fastening surface between the part and the base plate 1. This type of application is shown in Figure 6 .
  • the side supports 4 can be fastened to the base plate 1 by welding, for instance.
  • the side supports 4 can be cut from a plate-like material, such as steel plate.
  • the L-shaped side supports used in the embodiment of Figure 6 are made in this manner.
  • the centre supports 5 can be made in the same manner as the side supports 4.
  • the shape of the centre supports 5 can also vary; in the embodiment of Figure 6 , the centre supports are separate, substantially rectangular pieces. It is, however, possible to make the supports in such a manner that the side support and centre support are made up of one and the same element, if this is considered necessary.
  • the side supports and/or centre supports can also be made of a bar-like material, etc.
