Definitions

  • the invention relates to a composite steel construction for floor slabs according to the preamble of claim 1.
  • the storey ceilings often consist of prefabricated ceiling elements made of steel or prestressed concrete, in particular so-called filigree plates with an additional in-situ concrete layer or hollow perforated plates.
  • EP 0 467 912 B1 discloses a plate carrier system whose carrier consists of welded steel plates which form a trapezoidal cavity.
  • the prefabricated ceiling elements rest respectively on the cantilever horizontal lower flange, which is integrally formed on the webs.
  • the lower end of the box forms a welded sheet metal, which is offset from the projecting belt plate inwards / upwards.
  • an additional fire protection panel from the outside.
  • a disadvantage of this construction is that due to the low height of the carrier whose rigidity is not sufficient for the load case assembly. Therefore, depending on the length of the carrier, only one or more supports have to be installed for assembly in order to limit the deformation of the carrier during the concreting process. Furthermore, it is disadvantageous that the tension of the steel beam is not protected by the construction itself in case of fire, but must also be covered with a fire protection layer.
  • EP 0 292 449 B1 discloses a concrete, fire-resistant steel support which interacts with concrete and consists of two mutually facing U-profiles, which are fastened on a support plate.
  • the carrier plate serves as a support for the precast concrete elements.
  • the cavity which is formed by the two U-profiles, shed with concrete.
  • For the case of fire inside the support are also provided extending straight in the longitudinal direction of the carrier reinforcing elements, which may also be biased.
  • this carrier can not be used without support in the case of load assembly, as its pressure range in the installed state consists only of the flanges of the two U-profiles and the connecting elements and therefore does not have sufficient stability.
  • the steel beam disclosed therein is composed of two T-beams, which are welded parallel to each other and with their flanges in a plane along their adjacent longitudinal edges.
  • the two plane-parallel webs carry with their free edge a thick sheet, which provided on its upper side with head bolts is and may have openings. Further openings are provided in the transition region between the webs and the thick sheet metal.
  • the steel beam thus prepared is supported with its flanges downwards between two supports. Subsequently, prefabricated ceiling elements are placed on both sides of the carrier on the flanges. After laying the reinforcement, the cavity of the steel girder and the prefabricated ceiling elements are supplemented by an in-situ concrete layer.
  • a steel beam which consists of a rolled section, in particular an I-profile, which is connected on both sides via a strut framework made of sheets with a trough-shaped bottom flange, which is arranged at such a distance from the rolled section is that between the lower edge of the rolled section and the Untergurtblech a concrete layer can be introduced.
  • the upwardly folded lower belt plate in turn serves as a support for the precast concrete slabs in the assembled state.
  • the load-bearing behavior of the frame and ceiling system is sustainably influenced by the connections or connections between supports and columns.
  • the frame construction allows flexible use of buildings, since neither stiffening walls nor associations disrupt the layout; However, in order to provide sufficient structural integrity, it is necessary to consider their rigidity and bearing capacity for bending moments in the design of the joints.
  • the usual beam-support connections differ mainly in the execution of the connection of the steel parts. Usually, these require a lot of effort in terms of design, manufacture and assembly, especially when requirements are placed on fire protection.
  • the steel girders rest fully on the lower columns.
  • the reinforcement can be arranged continuously, regardless of whether it is a construction in which the in-situ concrete slab is provided on the upper carrier belt or on the lower belt as a slim-floor construction.
  • For the additional supports connections must be provided in the carrier.
  • foot anchors of columns are very complex and the columns have to be reoriented for each floor, this is a very costly and time consuming solution.
  • prefabricated concrete columns made of reinforced concrete are increasingly used in frame structures, since the production cost and thus their production costs do not increase in fire protection requirements.
  • the present invention seeks to provide an economical design for fire-resistant frame and floor slab constructions.
  • the carrier Due to the increased height of the carrier and the bias of the tendons in its interior, the carrier is stiffened so that the required deformation restrictions can be met in the mounting load case without installation of additional mounting brackets.
  • the lightweight construction of sheet metal and prestressing steel simplifies transport and installation of the girders, even with large spans.
  • the steel-composite construction creates a fire-resistant construction.
  • a solid concrete section If the cavity of the box girder and the joints between the support and ceiling elements are cast with concrete, the ceiling elements are encased in concrete round the ends. This means that the ceiling elements are better protected in case of fire, since they do not rest directly on a steel flange, which immediately loses its stiffness under the influence of heat.
  • the shear resistance of the ceiling elements in particular of the hollow perforated plates is heavily dependent on the rigidity of the support. Due to the encapsulation of the support area with concrete after installation of the ceiling elements and by filling the cavities in the elements in this area, the risk of shear failure in the support area is considerably reduced.
  • Another stiffening possibility for the supporting structure is, in a frame or floor slab construction in steel-concrete composite construction a create moment-loadable connection with the help of reinforcing elements.
  • the proposed compound according to the invention simultaneously meets the fire protection requirements, which are also placed on the ceiling beams, columns or ceilings, so that additional measures such as fire protection paneling, paints or the like as in the classic steel construction connections, which are common in steel composite construction, are dispensable.
  • FIGS. 1 to 4 each show a support situation of a floor slab 1 of the steel composite structure according to the invention consisting of prefabricated ceiling elements 2 made of reinforced concrete and an associated box girder 3 made of steel in the state of assembly.
  • the box girder 3, whose upper flange 4 with two inwardly inclined webs 5 and a lower flange 6 forms a substantially trapezoidal cross section, consists of welded steel sheets.
  • the lower flange 6 projects on both sides beyond the trapezoidal cross section (6a).
  • the length of the projecting parts 6a of the lower flange 6 in each case depends on the span of the ceiling elements 2.
  • tendons 7 are guided. These can, as shown in Fig. 5, consist of steel wire strands, but also of tie rods or wires.
  • tendons 7 sheets 8 are welded with supports at the deflection points 8a in the box girder 3. Also for supporting and anchoring the tendons 7 at the ends of the box girder 3 plates 9 are provided, against which the anchoring elements 7a are supported.
  • openings 10 and 11 are provided in the webs 5 and 4 in the upper flange openings 10 and 11 . These openings 10, 11 are required, on the one hand, to insert additional reinforcement elements 15 after assembly of the ceiling elements 2 (FIG. 1) and, on the other hand, to introduce and compact the concrete for the final state of the steel composite construction. This creates a frictional connection of box girder and concrete.
  • the ceiling elements 2 have at their ends at the top recesses 14 to allow the insertion of the reinforcing elements 15 and further bracket 16 and at the same time the subsequent introduction of cast-in-situ concrete.
  • the cavities of the ceiling elements 2, in particular in hollow perforated plates are sealed by specially shaped closures 13 against ingress of in-situ concrete.
  • the ceiling elements 2 in the assembled state 3 spacers 12 are placed on the projecting parts 6a of the lower flanges 6 of the box girder, which may consist of wood, concrete, plastic or the like.
  • the gap between the ceiling elements 2 and the lower flanges 6 is in each case laterally turned in (FIG. 1).
  • the projecting parts 6b of the lower flange 6 of the box girder 3 are angled upwards and thus formed trough-shaped.
  • the ceiling elements 2 can be placed here on the angled parts 6b of the lower flange 6 in the assembled state. Due to the trough shape can be dispensed with an additional formwork during the concreting process.
  • a continuous longitudinal reinforcement 17 on the lower flange 6, which can also be designed according to the building supervisory requirements as a ring armor reinforcement.
  • FIGS. 3 and 4 show further embodiments of the lower flange 6.
  • the protruding parts 6c are bent at a planar design of the lower flange 6 at a radius upwards.
  • the entire lower flange 6 including the projecting parts 6d is arcuately curved. If the customary in the floor-mounted suspended ceiling is omitted, can be achieved by the geometric shapes of the lower flanges 6 architecturally aesthetic effects.
  • box girder 3 of the steel composite construction according to the invention is shown in FIG. 5 as a single-field girder, it goes without saying that other static systems of the box girder with continuous action are also possible.
  • the tendons 7 are then guided and fixed according to the course of the bending moments of constant load and traffic load inside the carrier 3.
  • a ceiling support 21 of a floor slab 1 is connected on one side to an edge support 22.
  • the edge support 22 is a reinforced concrete support that was prefabricated in a precast plant, transported to the construction site and mounted there.
  • a built-in part 24 was arranged in the form of a steel plate in this.
  • reinforcing elements 25 in particular for receiving bending moments, in the present case a Einspannmoments, here two steel bars are shown, which extend parallel to each other and the upper flange 4 of the box girder 3 and anchored by a steel plate 26 in the support 22.
  • the reinforcing elements 25 could be executed in an angular shape and the occurring Forces are introduced via composite action in the support 22. This solution is not shown.
  • reinforcing elements 25 which must already be embedded in concrete during production of the support 22 and therefore protrude beyond its outer surface, do not hinder the production and during transport of the support 22, these can also be provided with a thread in the region of the installation part 24 and by a Socket joint are encountered.
  • a support bracket 27 is attached to the mounting part 24, for example, welded, screwed or plugged.
  • the cavity of the box girder 3 and the gap 28 between this and the support 22 are filled with in-situ concrete 23.
