Definitions

  • the invention relates to a steel beam arranged to act together with concrete as a supporting composite structure for different slab systems, the composite structure being arranged to be supported at least at supporting points at the area of the ends and comprising two web parts and horizontal cantilever parts extending outside thereof, the web parts being arranged adjacent at a distance from each other and interconnected at one edge of each web part by means of a horizontal upper part, the web parts and the horizontal upper part being arranged to constitute a space that can be filled with concrete.
  • steel beams of the above type so-called steel composite beams
  • steel composite beams have long been known in the construction industry.
  • these steel composite beams act as a steel beam for installation-time loads.
  • the beam acts as a composite structure together with the concrete.
  • the beam is cast full of concrete in connection with the joint grouting of the slabs and a possible topping.
  • Steel composite beams are either single-span or plural-span beams. This means that the beam is supported either at its ends, i.e. in the area of the supporting points in the area of its ends or, alternatively, it comprises intermediate supports such that the beam also includes supporting points between the supporting points in the area of its ends. This is why it is not practical to make the beam similar over its entire length, but additional steel parts are fastened to the basic cross-section according to stresses.
  • the beam is subjected to a high shearing stress in the vicinity of the support arranged in the supporting point.
  • this high shearing stress has been received by welding a chamfered plate inside the beam in the vicinity of the supporting point.
  • the drawback in the above structure is that the plate increases the weight of the beam and thereby its price.
  • the plate is also difficult to fasten on a production line because the welding position is unfavourable since, in practice, the labourer has to bend and at the same time reach up- wards.
  • the shearing force decreases linearly from the end of the beam towards the middle.
  • the plate is of uniform section, its thickness being determined according to the highest value of the shearing force. Thus, part of the capacity of the plate is unnecessary and remains unutilized.
  • the object of the invention is to provide a steel beam allowing the drawbacks of prior art to be eliminated. This is achieved with a steel beam of the invention.
  • the steel beam of the invention is characterized in that at least one peg member whose one end is fastened to the lower surface of the upper part and whose other end is provided with an anchoring expansion or widening section is arranged inside the space defined by the web parts and the horizontal upper part, in the area of the supporting points.
  • An advantage of the invention over prior art is that the peg members are light and their number can be changed very easily over the length of the beam. Accordingly, superfluous capacity and weight are not created in the beam.
  • An additional advantage of the invention is that the peg members are much easier to fasten to the beam than the previously used plate.
  • the peg members can be fastened to the plate constituted by the upper part of the beam from the top, i.e. the welding can be carried out from above for instance by placing the peg member into a hole provided in the plate. This eliminates the inconvenient working position caused by the welding of the previously used plate.
  • Figure 1 shows a steel beam according to the invention seen in the longitudinal direction of the beam
  • the lower edges of the web parts 1 are interconnected by means of a horizontal lower part 5.
  • the web parts 1 are provided with openings 6 enabling the feed of concrete into the space 4.
  • peg members whose ends comprise an expansion or widening section acting as an anchoring are used in the vicinity of a supporting point.
  • at least one peg member 7 is arranged inside the space 4 defined by the web parts 1 and the horizontal upper part 3, in the area of the supporting points.
  • One end of the peg member 7 is fastened to the lower surface of the upper part, as shown particularly clearly in Figure 1.
  • the other end of the peg member 7 is provided with an expansion or widening section 8 that helps the anchoring.
  • the number of peg members 7 over the length of the beam may change, avoiding unnecessary capacity. Accordingly, there may be either one or more peg members 7 according to the need, and the number may also change e.g. in the longitudinal direction of the beam.
  • the peg members 7 may be placed in either one or more lines.
  • Figure 1 shows a solution wherein the peg members are in two lines. The peg members 7 are placed in the area of the supporting points, i.e. at the ends of the beam and, if need be, also in the area of the supporting points between the ends of the beam.
  • the peg members can be made either from a smooth bar or from a ribbed bar.
  • the shape of the expansion or widening section 8 acting as the anchoring end is optional as long as it constitutes an anchoring member.
  • the shape of the anchoring end can be e.g. round, oval, etc.
  • the expansion or widening section acting as the anchoring end can be implemented by using any suitable technique.
  • the peg members 7 are made from jolt pegs has been found to be particularly advantageous.

Abstract

Cette invention concerne une poutre d'acier conçue pour coopérer avec du béton en tant que structure composite portante pour différents systèmes de dalles. Cette structure repose sur des points porteurs situés à proximité des extrémités et comprend deux parties âme (1) et des parties horizontales (2) s'étendant à l'extérieur de celles-ci. Les parties âme (1) sont adjacentes à une certaine distance les unes des autres et sont interconnectées au niveau d'un bord de chaque partie âme (1) au moyen d'une partie supérieure (3). Les parties âme (1) et la partie supérieure (3) forment un espace (4) pour le béton. La poutre d'acier comprend au moins un élément de piquet (7) dont une extrémité est fixée à la partie supérieure (3) et dont l'autre extrémité est munie d'une partie d'extension ou d'élargissement d'ancrage (8). L'élément de piquet est situé à l'intérieur de l'espace (4) défini par les parties âme (1) et la partie supérieure (3), à proximité des points porteurs.
