Definitions

  • the present invention relates to a device for connecting a beam of a composite ceiling to a support, a component and a method for erecting a building with at least one composite ceiling.
  • the object of the invention is to reduce this workload in order to be able to erect structures having composite ceilings more quickly.
  • the carrier is pivotally connected to the support about an axis lying in a normal plane to the support.
  • the invention provides a component which consists of a support with supports pivotably connected thereto, the pivot axes lying in one or more spaced normal planes to the support.
  • the method according to the invention for the erection of a building with at least one composite ceiling provides that supports with supports connected to them about a pivot axis lying in a normal plane to the support are set up, the supports being folded approximately parallel to the support during installation, and that then the beams are folded out into a position approximately at right angles to the column and, after the formwork has been attached, are concreted in for the composite floor.
  • the component according to the invention can be delivered prefabricated to the construction site, with supports for several floors, i.e. for several composite ceilings to which the support can be pivotally connected. Due to the pivotable connection of the beams to the column, it is possible to transport the column in a space-saving manner with beams aligned approximately parallel and folded onto the column and to position them at the appropriate place in the building. Only then are the beams folded out into a position approximately at right angles to the support and concreted in together with the reinforcements after the formwork has been attached to the composite floor.
  • the girder is designed in such a way that in the unfolded position in which the girder is concreted in, a moment-transmitting connection of the composite ceiling to the support is created.
  • the carrier has a T-shape, the central web protruding upward from the cross flange and the cross flange resting directly or indirectly on the support, at least under load.
  • a preferred embodiment variant provides for a structurally simple connection of the carrier to the support that a connecting strap with a through fixed bore, preferably welded, and that the central web of the
  • Carrier in the connection area has a corresponding through hole, the carrier being pivotally connected to the support by a pivot bolt passing through both through holes.
  • the relative position of the carrier to the support in the extended position can be adjusted by means of fitting plates inserted between the transverse flange and the support.
  • the adapter plates also ensure that the cross flange lies firmly against the support, so that occurring loads are passed on directly and without play from the cross flange to the support.
  • the transverse flange is provided with a large number of pin-shaped elements, in particular protruding nails or bolts.
  • a peg is attached to the support for introducing transverse forces, preferably welded on, the carrier in the unfolded position on the peg lies on.
  • the carrier which is shorter than the distance between adjacent supports, is only connected on one side to a support. This is achieved through the torque-transmitting connection.
  • FIG. 1 shows a device according to the invention in side view
  • FIG. 2 shows a device according to the invention in the associated view from above
  • FIG. 3 shows a section through a carrier
  • Fig. 4 shows a component according to the invention with the supports folded and
  • Fig. 5 shows a component according to the invention with differently opened
  • the device according to the invention relates to modern buildings in which a plurality of supports supports the composite ceilings which divide the building into storeys downwards on the foundation.
  • a plurality of supports supports the composite ceilings which divide the building into storeys downwards on the foundation.
  • One of these supports 1 is shown in FIGS. 1 and 2.
  • the support 1 is designed as a hollow profile support made of steel, a steel core 7 being additionally provided in the interior of the support 1.
  • the support 1 is provided with dowels or nails 8, which form a reinforcement of the cavity that can be filled with concrete around the steel core 7 and transmit the forces introduced from the outer hollow profile of the support 1 into the interior.
  • a connecting bracket 6 is welded to the support 1 and is provided with a through hole.
  • a collar 9 made of steel is additionally welded to the support 1. Both the connecting strap 6 and the collar 9 serve to introduce the forces absorbed by the carrier 2 into the support 1.
  • the carrier 2 is provided with a multiplicity of pin-shaped elements 5 to absorb the forces from the composite ceiling formed within the dashed lines of reinforced concrete 4.
  • the pin-shaped elements 5, for example nails, screws or bolts, are - as can be seen from FIG. 2 - arranged on the horizontal transverse flange 2b of the carrier 2.
  • the pin-shaped elements are either welded to the cross flange or, if they pass through the cross flange 2b, fixed by means of a screw connection.
  • the carrier 2 has on its central web 2a in the connection area a through hole corresponding to the through hole of the connecting plate 6, so that the carrier 2 can be pivotably connected to the support 1 by means of a pivot bolt 3 passing through the two through holes.
  • the pivotable connection enables the economical production of the component shown in FIGS. 4 and 5, which consists of a support 1 with a plurality of supports 2 connected to it.
  • the support 1 can be up to 20 m long and have 2 beams for several storeys that can be folded out at spaced levels.
  • the component can be easily transported in the form shown in FIG. 4 with the supports 2 folded down.
  • the carrier 2 are only at the construction site after positioning the
  • Support 1 folded out into a moment-transmitting position approximately at right angles to support 1 and concreted in after the installation of formwork for the composite floor.
  • the cross-sectional shape of the carrier 2 which can be seen in FIG. 3, is essential for the torque transmission.
  • the transverse flange 2b of the carrier 2 enables the pressure forces resulting from the moment M to be introduced into the column 1.
  • the introduction takes place indirectly via the adapter plates 10 and the collar 9, it being essential that all components involved (support, carrier, collar, adapter plates) ) are made of steel.
  • Carrier 2 to support 1 can be set exactly.
  • the main function of the peg 9 is to absorb the transverse forces Q which result from constant loads and payloads.
  • the carrier 2 rests with its central web 2a on top of the peg 9.
  • a classic tensile reinforcement arranged in the upper area of the concrete 4 ensures the torque-transmitting connection of the composite slab to the column 1. This tensile reinforcement interacts with the introduction of pressure via the transverse flange 2b in the lower area of the composite slab.
  • a lost formwork can be on the supports 2 be fixed for the reinforced concrete 4, whereby a classic formwork, which is associated with high labor costs, can be dispensed with.
