Definitions

  • the invention relates to a support beam for ceiling systems according to the preamble of claim 1.
  • Such support beams are often used in reinforced concrete or composite construction, in particular in the construction of ceiling systems or storey ceilings.
  • the EP 1 611 295 B1 a generic support beam.
  • This has a hollow box cross-section and serves as a support for plate-shaped semi-finished parts or prefabricated parts. After laying the semi-finished or prefabricated parts, a local or large-area in-situ concrete layer is applied, which also penetrates into the interior of the hollow box cross-section of the supporting beam in order to produce the composite ceiling system.
  • these support beams which are only made of steel, when connecting to the ceiling panels on the construction site, in-situ concrete is introduced into the space of the support beam, which is defined by the webs, a base plate and an upper plate (top flange) opposite the base plate (bottom flange) .
  • the supporting beam has in particular a carrier, in particular a steel carrier, which has a base plate and at least one, preferably two, web or webs arranged at an angle to this, in particular perpendicularly.
  • the supporting beam is characterized in that a space delimited by the web or the webs and the base plate, preferably each made of steel, is at least partially filled with concrete, which is preferably not in-situ concrete, or the space between the web and the base plate or The webs and the base plate are at least partially filled with concrete, which in particular is not in-situ concrete.
  • Steel and concrete work together here in a composite construction. Reinforcing steel in the form of stirrups and rods can be inserted into the concrete to absorb forces and to increase the bond effect.
  • the supporting beam in composite construction is used according to the invention in a ceiling system in composite construction, the supporting beam being used to support at least one semi-prefabricated part or prefabricated part and an in-situ concrete layer, in particular outside the concrete, which defines the space delimited by the web or the webs and the base plate or the space between the web or the webs and the base plate at least partially fills, is provided at least in the connection area between the at least one support beam and the semi-finished part or prefabricated part.
  • a ceiling system in composite construction which has at least one supporting beam according to the invention, at least one semi-finished part or prefabricated part, which is supported on the at least one supporting beam, and an in-situ concrete layer, which at least in the connection area between the at least one supporting beam and the semi-finished part or Prefabricated part is provided, in particular outside the concrete, which at least partially fills the space between the web or the webs and the base plate or the space delimited by the web or the webs and the base plate.
  • a method for producing a ceiling system in composite construction namely with the steps of supporting at least one supporting beam according to the invention on supports, supporting at least one semi-finished part or prefabricated part on the at least one supporting beam, providing composite elements in the connection area between the at least one supporting beam and the semi-prefabricated part or prefabricated part, provision of an in-situ concrete layer at least in the connection area between the at least one supporting beam and the semi-prefabricated part or prefabricated part, in particular outside the concrete, which at least partially fills the space between the web or webs and the base plate.
  • the supporting beam is produced in and for the composite construction in several production steps.
  • reinforcement cages consisting of stirrups and steel bars and then later concrete can be introduced into the supporting beam at a later moment, so that initially a semi-finished part is present that, in addition to the steel girder, has composite means, in particular form-fit means, for creating a form fit with the concrete to be filled .
  • the support beam already has before the connection with semi-finished parts or Precast concrete on.
  • the concrete is provided at least in sections in this space before the connection with the prefabricated part or semi-finished part, i.e. before the in-situ concrete layer is provided in the connection area between the supporting beam and the semi-finished part or prefabricated part.
  • the support beam as such therefore already has at least some sections of concrete that is not in-situ concrete before it is connected to the prefabricated or semi-finished part in the space delimited by the web or webs and the base plate or in the space between the web or webs and the base plate .
  • this space is completely filled, except for the through openings, around possible steel reinforcements, with concrete that is not in-situ concrete.
  • the supporting beam according to the invention in composite construction already has concrete during assembly, that is to say before it is connected to the ceiling system by in-situ concrete, it can take the load of the ceiling or the prefabricated part or semi-finished part reliably during assembly, over its entire length, without the need to use intermediate or auxiliary supports.
  • a pressure zone is already present in the delivery state; No additional support is then required even for laying ceiling elements, since the pressure zone is already (preferably completely) formed by the concrete with or without reinforcement.
  • the construction height of the supporting beam corresponds to the height of the ceiling system plus the thickness of the base plate.
  • the construction height of the ceiling system can thus be minimized, which leads to a reduction in the construction volume without having to reduce the usable area at the same time.
  • the arrangement of steel and concrete in the supporting beam can be optimized with regard to the requirements for compressive strength. This is because the space or the space between the web or the webs and the base plate bounded by the web or the webs and the base plate is at least partially filled with concrete, which is preferably not in-situ concrete, the pressure zone of the beam for the Traffic load case is.
  • the use of concrete instead of a steel belt reduces the weight of the support beam.
  • the invention is based on the idea of using a supporting beam in ceiling systems, the supporting beam as Composite component itself has concrete before it is connected to the ceiling system.
  • the supporting beam as a prefabricated composite part as such has not only steel but also concrete, it can also be viewed as a "hybrid beam".
  • a so-called steel-concrete composite beam or “composite beam”
  • the tensile stress is taken over by the steel component and the compressive stress is largely taken over by the concrete component. Strong forces can be absorbed by inserted pressure reinforcement.
  • the base plate is to be understood in particular as the lower chord.
  • the base plate and the web arranged at an angle thereto or the webs arranged angled thereto and protruding from the same side of the base plate define the space in which the concrete is provided at least in sections.
  • the arrangement of the base plate and the webs is preferably U-shaped in cross section perpendicular to the longitudinal direction of the support beam.
  • One possible shape also provides for a web in the middle with the base plate below in a concrete beam.
  • the space for creating the concrete beam is then defined by auxiliary formwork on both sides.
  • More than two webs, for example a central web and two lateral webs, can also be implemented to delimit space at the side.
  • the base plate can be stiffened laterally by transverse rib webs and thus receive more load-bearing capacity. These rib webs are then to be coordinated with the ceiling elements to be placed by means of cutouts or limitations, dimensions, so that they can nevertheless rest on the base plate.
  • the concrete is any concrete, preferably a high-strength concrete, for example SCC.
  • a class C 60/75 concrete can with chemical Plasticizers can be used as additives or mixed carbon fibers or glass fibers.
  • the concrete is preferably high-strength concrete (cylinder strength between 50 N / mm 2 and 100 N / mm 2 (C 100/115)).
  • the concrete can be reinforced concrete (preferably reinforced concrete reinforced with reinforcing steel stirrups and bars). The concrete filling can therefore be carried out with or without reinforcement.
  • additional bonding agents are arranged. These can be formed by shaping the steel parts and / or by additionally applied composite bodies such as head bolts, perforated sheet metal strips and / or structured parts that transfer forces between concrete and steel.
  • the space filled with the concrete at least in sections is open at least in some areas, preferably completely, on the side facing away from the base plate.
  • the carrier is preferably free of an upper steel plate running parallel to the base plate, i.e. an upper belt made of steel, which delimits the space between the webs and the base plate, so that the space without an opposing plate is referred to as open.
  • the steel belt can therefore be dispensed with.
  • This embodiment has the advantage over the use of an additional upper plate, that is to say a steel belt, that the weight of the supporting beam is reduced by using less steel.
  • the use of concrete in this pressure range is advantageous because steel is less pressure-resistant than concrete.
  • the space to be filled with concrete is at least partially, preferably completely, open on the side facing away from the base plate, the concrete can be filled more easily, namely directly from above instead of laterally through the webs. This means that no bubbles form in the concrete, which makes the manufacture of such a supporting beam further easier and more reliable.
  • the concrete protrudes over at least one web by an overhang, the overhang preferably extending in a direction perpendicular to the base plate.
  • the overhang is preferably dimensioned in such a way that the overhang is flush with the ceiling plate. Then it is not necessary to provide concrete.
  • the overhang can be a reinforced concrete body.
  • the protrusion preferably has a toothing, in particular a longitudinal groove. These teeth can absorb the horizontal transverse forces.
  • the toothing also serves to create an overall load-bearing effect between the supporting beam and the ceiling elements placed on it as a rigid ceiling pane. In special cases, it is possible to apply additional in-situ concrete layers to achieve higher ceiling rigidity.
  • One embodiment can have a hanger basket.
  • Reinforcing steel preferably in the form of longitudinal bars, be arranged.
  • the bracket cage and the reinforcing steel can be surrounded by concrete at least in sections, preferably completely. This arrangement of reinforcement in cooperation with the surrounding concrete then represents reinforced concrete which at least partially fills the space delimited by the web or the webs and the base plate.
  • the connecting means can extend through intermediate spaces in the hanger cage in the direction transverse to the longitudinal direction L, that is to say in the transverse direction. This can strengthen the composite effect.
  • the inner surfaces of the web or webs i.e. the surfaces that define the space between the webs on the inside, and / or the base plate, i.e. the side of the base plate that defines the space between the webs and the base plate on the inside, have bonding agents.
  • This can also mean that the web or the webs and / or the base plate itself are designed in such a way that they act as a connecting means.
  • Composite means can also be arranged integrally or additionally on the inner surface of the web or webs and / or the base plate. Bonding agents improve the bond between the beam and the concrete.
  • the composite means also preferably has form-locking means, in particular headed bolts. These can in particular extend at an angle from the webs into the space, more preferably essentially parallel to the base plate and perpendicular to the webs arranged perpendicular to the base plate.
  • composite bolts can also be provided from the base plate, preferably running parallel to the webs, and / or several composite bolts, which extend from a web, preferably perpendicular to the base plate and are variable in terms of their distance from the base plate, preferably displaceable along the web.
  • composite means for forming a form fit can be implemented as desired, as long as they, and thus the webs and / or the base plate, are designed to absorb and transmit composite transverse forces. They can, for example, be depressions and / or projections that enable a toothing between the webs or the base plate and the concrete.
  • a wave-like shape is conceivable on the inside of the webs or base plate, for example in that correspondingly wave-shaped sheets or sheet metal strips with a force-introducing effect as a composite material that are perforated, twisted or otherwise structured in the longitudinal direction are arranged on the inside and welded to the webs or the base plate .
  • Another option is a bar with cutouts.
  • the individual elements of the supporting beam themselves by appropriate shaping, for example such as corrugation, folds, indentations or other shapes, in interaction with the concrete, transmit forces especially in the longitudinal direction between concrete and steel parts.
  • the supporting beam can also be higher than the ceiling elements placed on top.
  • the webs are designed to be corrugated or folded on the upper side by an upstream local shaping process. This not only helps to transfer the bond forces between concrete and steel, but it also makes it possible to bend or arch the side bars before welding them to the base plate in order to create a curved supporting beam. Ease of manufacture is therefore of economic and technical importance.
  • the supporting beam can preferably have an elevation which preferably corresponds to a later deflection.
  • These supporting beams which are produced with so-called canting, have advantages for the perceptible small deflection in the finished structure, because the deflection when the ceiling elements are applied and the canting are more or less canceled out. In any case, whether with deformed upper web elements or flat web elements, this is easier to produce with a supporting beam without a steel belt than with an upper belt, because fewer parts have to be held and welded.
  • An arrangement of several strips or sheets in the horizontal or vertical direction, next to one another, for example parallel, and / or at different depths of corrugations or projections and depressions can be designed as desired.
  • the supporting beam can furthermore have through openings which extend transversely to the longitudinal axis of the supporting beam through the webs and preferably also through the concrete provided in the room. These, mostly periodically repeating through openings are used to accommodate composite elements that are in the connection area between the supporting beam and the Semi-finished part or finished part are provided. This means that the shear forces in the ceiling system can be reliably absorbed.
  • Reinforcing steel can also be picked up or pushed through. This can serve to achieve a stiffening ceiling pane effect. Depending on the height arrangement of the openings, this can be done through protruding reinforcement steel in the ceiling elements or reinforcement placed on top.
  • the connecting means or bolts preferably have at least the same distance from the base plate as the through openings. A greater distance between the composite means or form-fit means from the base plate than from the projection is conceivable. This is advantageous in the event of a fire.
  • the in-situ concrete layer of the ceiling system is therefore preferably provided to the side of the webs around the toothing and through the through openings in the supporting beam and preferably at least partially above.
  • the connection area between the supporting beam and the semi-finished part or prefabricated part is to be understood in particular as the area of the through openings of the supporting beam and the upper area in which the protrusion has the toothing.
  • the base plate can have at least one projection which protrudes transversely to the longitudinal axis of the supporting beam via at least one web, an elastic damping element preferably being provided on the at least one projection. More preferably, they are provided on both sides of the webs which are on the outside of the space defined by the two webs. It is therefore envisaged that the webs are arranged offset inward from the edges of the base plate, so that the areas of the base plate outside the webs serve as projections.
  • a prefabricated part or semi-finished part, in particular a ceiling plate, can be supported on the projection or projections. If an elastic damping element is also provided, the support is optimized.
  • the damping element can for example be an elastomer with a thickness of 3-5 mm, a width of preferably more than 30 mm, which has a load-bearing capacity of up to 15 N / mm 2 .
  • the damping element can be continuous and / or linear; it can also be formed selectively.
  • the base plate or the carrier can have a fire protection layer.
  • This is preferably applied at least in sections in the space between the webs - that is, in the supporting beam - on the base lath, this layer being arranged in the space between the webs before the provision of concrete.
  • a fire protection layer can also be applied particularly effectively, alternatively or additionally, on the outside, that is to say on the side of the base plate facing away from the webs or on the underside of the base plate, at least in sections along the base plate.
  • the fire protection layer can, for example, be a PROMATECT® fire protection building board or a foaming agent.
  • the fire protection layer can be a paint or have such a paint.
  • the steel base plate transmitting the tensile force of the bending beam can be protected particularly effectively against overheating and premature failure in the event of a flame from below.
  • the selective arrangement of the expensive fire protection measures is only economical in the area of greatest impact.
  • Fig. 1 shows a supporting beam 1 with a carrier 10 which is made of steel and has a base plate 12 and two webs 14 and 16 arranged perpendicular to the base plate 12.
  • the two webs 14 and 16 extend on the same side of the base plate 12 essentially parallel to one another and perpendicular to the base plate 12, that is to say in a U-shape.
  • the two webs 14, 16 and the base plate 12 define a space which is filled with concrete 2.
