Definitions

• the invention relates to a steel beam that is arranged to serve together with concrete as a bearing composite structure for various slab systems, the composite structure comprising a base plate and two web parts arranged side by side at a distance from each other and joined at first ends of the web parts by means of a horizontal top part, whereby the base plate, web parts and horizontal top part are arranged to form a space that can be filled with concrete.
• the steel beam of the invention is charac- terized in that at least one web part is made of a plate part formed of two longitudinal parts of the beam that are at an angle to each other, and that the plate part is fastened to the base plate and top part in such a manner that the lower part of the web part is at an angle to the base plate and the upper part is substantially perpendicular to the base plate.
• the steel beam of the invention is also simple, whereby the introduction and use of the invention are advantageous.
• a further advantage of the invention is that it can be modified as neces- sary, whereby its use is advantageous.
• a yet further advantage is that the beam of the invention can be manufactured in the same manufacturing lines as the prior-art beams.
• Figure 2 is a perspective view of the beam of Figure 1
• Figure 3 is a longitudinal view of a second embodiment of the steel beam of the invention
• Figure 4 is a perspective view of the beam of Figure 3.
• both web parts 2, 3 are made of a plate part, the parts 2a, 2b and 3a, 3b, respectively, of which are at an angle to each other.
• This type of solution is, however, not the only possible solution, and the invention can also be applied in a slightly different man- ner.
• Figures 3 and 4 show a second embodiment of the invention.
• the same reference numerals as in Figures 1 and 2 are used in Figures 3 and 4 for corresponding items.
• FIG. 3 and 4 differs from the em- bodiment shown in Figures 1 and 2 in that in the embodiment of Figures 3 and 4, only one web part 2 is made of a plate part, the parts 2a, 2b of which are at an angle to each other.
• the second web part 3 is made of a straight plate part without openings.
• a beam suitable for edge structures refers herein to the beam forming the edge of a structure, such as a plane of a building, in such a manner that the opening-free web part 3 forms the edge surface of the plane.
• side supports 7 and centre supports 8 which are shown with dashed lines in Figure 3.
• the side supports 7 and centre supports 8 can be arranged on the base plate 1 at regular intervals in the longitudinal direction of the beam. They can be fastened by welding, for instance.
• the side supports 7 are arranged to determine the position of the web parts equipped with openings 6 in relation to the base plate 7 and the centre parts 8 are, in turn, arranged to determine the location of the plate forming the top part 4.
• the side supports 7 can be L-shaped, for instance, as in Figure 3.
• the side supports and centre supports can for instance be cut from a plate material.
• the invention can also be applied in such a manner that the web parts 2, 3 are cut to a curved shape according to the pre-cambering of the beam.
• the use of the side and centre supports is especially advantageous, since the side and centre supports support and guide the web parts and the horizontal top part very effectively during the manufacturing stage, in which the base plate is bent to the curvature according to the web plates.
• the plate forming the top part 4 is also shaped by means of the centre supports to the correct curvature.
