Definitions
- the invention relates to a steel beam for precast slabs according to the preamble of patent claim 1.
- ceiling constructions In building construction, various methods are known for the construction of ceilings. In addition to pure wood or steel ceilings, ceiling constructions made of concrete are used in particular. For their preparation, for example, prefabricated, reinforced concrete precast ceilings are used, which are poured over after installation with in-situ concrete and connected to the carrier.
- ceiling slabs are not laid on the upper flange of the steel girders, but the ceiling girders are arranged inside the slab, this is called flat steel slabs or even a slimfloor construction.
- flat ceilings are only between about 20 and 30 cm high, and usually have a span between 6 and 9 m. Depending on the choice of ceiling panel types, however, spans between 3 and 10 m are possible.
- prefabricated ceiling panels When using completely prefabricated ceiling panels (precast ceilings), the elements are placed on the bottom flange of the support. As steel beams become predominantly Double T-beam with widened bottom flange, Integrated Floor Beam (IFB), or with underfloor metal sheet, Slim Floor Beam (SFB), or also hat profiles.
- IFB Integrated Floor Beam
- FOB Slim Floor Beam
- the invention is therefore based on the object to provide a steel beam for precast ceilings, which in particular has a high bending stiffness at low meter weight and allows easy connection of the precast ceiling to the carrier. Also, a fire protection coating should be easy to apply.
- a carrier consisting of a lower flange and a web plate arranged thereon is used to solve this problem, in which the web plate is designed as a wave-shaped plate and is provided with a suitable for hooking with the reinforcement of the ceiling plate receiving device.
- the steel beam according to the invention has significant advantages over the previously customary carriers.
- the carrier is in this first embodiment, on the one hand inexpensive from standard steel components produced, he has by the waveform of the web plate between the straps high bending stiffness at low meter weight and can also be easily connected by an appropriate receiving device to the reinforcement of the precast ceiling.
- the receiving device for the reinforcement can be designed according to the invention in various ways, and are adapted to the best solution for the construction task.
- the receiving device may consist in the simplest form of introduced into the wave crests and valleys through holes into which the reinforcement of the ceiling plate can be hooked.
- the receiving device consists of at least one respectively between the wave crests and valleys arranged and suitable for hooking with the reinforcement of the ceiling plate strut.
- the receiving device can also consist of at least one each introduced into the wave crests and valleys through hole into which a suitable for hooking with the reinforcement of the ceiling plate strut can be introduced.
- the struts are advantageous inserted into previously inserted aligned holes in the web plate inserted, so that they can be inserted when inserting the ceiling plate in the protruding from the precast ceiling reinforcement bracket in a simple manner.
- two or more suitable for hooking with the reinforcement of the reinforced concrete slab struts are arranged so that a very intimate connection of the ceiling slab can be achieved on the carrier.
- the shape of the web plate may have any wavy structure, for. B. also a trapezoidal shape. It is important in any case that the wave height and width is adapted to the static requirements of the carrier.
- the wave-shaped web sheet itself can be cut, for example, as a strip from a corresponding wave plate or trapezoidal sheet or be bent accordingly from flat material.
- the web plate can also be composed of welded together individual sheet metal parts.
- the carrier may be provided in a second embodiment also with a top flange, which is divided as required or one-piece or longitudinally and provided with a gap on the web plate.
- the gap between the two parts of the upper flange thereby improves the incorporation of the concrete when casting the carrier profile.
- the web plate is advantageously arranged symmetrically to the central axis on the lower flange in a further embodiment of the invention.
- the lower flange is at least as wide as the wave height of the web plate, so that a sufficiently large support for the ceiling plate is present.
- the bottom flange may also be designed to be significantly wider in order to reduce the surface load on the bottom flange.
- the individual components are welded together.
- the web plate 2 is arranged symmetrically to the center axis of the web plate on the lower flange 1 and wider than the wave height of the web plate 2.
- the upper flange 3 is integrally formed in this example and also symmetrically to the central axis of the web plate 2 thereon.
- the wave crests and valleys of the web plate 2 are inventively provided with aligned through holes, in the horizontally offset two struts 4, 4 'are passed, can be hooked into the reinforcing bracket of a prefabricated ceiling, not shown here.
- prefabricated ceiling is made so that they flush with the top edge of the carrier, d. H. flush with the upper flange 3. After hooking the reinforcement with the carrier, this is then cast with in-situ concrete to produce a composite.
- FIG. 2 shows a variant of the carrier with a slotted top chord and a side end plate. The same components are marked with the same reference numbers.
- the top flange 3, 3 ' consists of two parts, which is provided with a gap on the web plate 2, to facilitate casting with in-situ concrete and to ensure an intimate bond between the carrier and precast ceiling.
- the carrier has laterally on the side opposite the ceiling connection side a cover plate 5, which projects at the level of applied screed, so that the carrier and applied screed flush.
- end plate 5 serves as a lost formwork for the grouting of the carrier with in-situ concrete.
