Definitions
- the invention relates to a composite beam in assembly design as a rigid connection of prefabricated ceiling panels.
- the steel structure consists of trusses with L-lower chords, e.g. U.S. Patent 19 79 643; 40 56 908, and DE-OS 21 23 351, or from honeycomb carriers according to US-PS 41 15 971.
- the individual ceiling tiles are prefabricated in transportable sizes in the workshop and put together on the construction site to form a ceiling or a bridge.
- the individual ceiling panels can be reinforced concrete panels or composite constructions with uniaxial steel constructions, the composite being carried out as in the local construction methods (DE-OS 21 53 495, US-PS 20 00 110).
- Composite beams with prefabricated ceiling panels are known e.g. from the bridge construction.
- prefabricated ceiling panels are screwed onto a double-T beam so that they are non-slipping (HV connection according to DIN 1050).
- the plate joints are filled with in-situ concrete.
- headed dowels or oarlocks are welded onto the top chord of a double-T beam in such a way that they protrude into recesses in the ceiling panels, which are filled with in-situ concrete. After the concrete has hardened in the panel joints and the recesses, a composite beam is available as a rigid connection for prefabricated ceiling panels. This type of design is also assumed in DE-AS 15 34 703 "ceiling construction in composite girder construction".
- Such composite beams have various disadvantages. What they all have in common is that the shear connection between the belts by means of composite means, such as non-slip screwing or oarlocks, has a single cut and therefore requires a high amount of composite means.
- the upper chord is weakened by individual recesses with inferior in-situ concrete filling or continuous loss of cross-section due to the space required for the screw connection.
- This has a particularly disadvantageous effect on edge beams because a distribution of the upper chord force in the ceiling tile results in cross-sectional twisting of the composite beam.
- the upper flange of the double-T profile is arranged under the ceiling panel in all of the above-mentioned designs, that is to say statically unfavorable and hardly used.
- a specific disadvantage of the composite girder mentioned last is the interruption of the bending stiffness of the ceiling slab transverse to the composite girder axis, which is mandatory with this embodiment. This makes e.g. cantilevering the ceiling panels is not possible or only with additional effort.
- the invention has for its object to provide a composite girder in assembly design as a rigid connection of prefabricated ceiling panels, which allows the necessary shear connection between the belts with less effort, which allows a statically better material utilization and which maintains the bending stiffness of the ceiling panels across the composite girder direction without additional effort.
- this object is achieved according to the invention in that the top flange and the web are divided into sections, the length of which in is essentially equal to the width of the associated ceiling tile that the upper flange and a part of the web of each section adjacent to it are embedded in the prefabrication of the ceiling tile, and that during assembly the web parts of each section projecting downward from the ceiling tiles with their lower Parts are connected to the continuous bottom chord.
- the top chord has no weakening recesses.
- the cross-sectional parts, in particular of the upper chord, are at the statically most favorable point.
- the bending stiffness of the ceiling tiles in the direction across the beam is undisturbed.
- the web or each web plate of each section consists of one half of a zigzag-shaped wide flat steel.
- the lower reinforcement of the ceiling slab can be guided transversely to the composite girder plane during the prefabrication through the openings.
- connection between the web of each section and the continuous lower chord must transmit the forces occurring from the web to the lower chord or from the lower chord to the web.
- Form-fit connections are best suited for this purpose, but they require tight tolerances during prefabrication. According to claim 4, therefore, non-positive connections are preferred in which the web and lower flange are pressed or clamped so tightly that the forces are transmitted directly from the web to the lower flange or vice versa by static friction.
- Slip-resistant screw connections are particularly suitable for this, in which screws made of heavy-duty material are tightened with a prescribed, high tightening torque and then press the elements to be connected together with a correspondingly high pressure. Such screws usually sit with play in the connection holes. It is therefore preferred according to claim 6, in each case open in the web downwards.
- FIG. 1 essentially shows the connection of a composite girder according to the invention, namely the parts of two web sections la, lb, two upper belt sections 2a, 2b and two ceiling plates 3a, 3b, which are adjacent to the connecting joint or the joint, and a continuous lower belt 4 , which consists of two L-profiles in the illustrated exemplary embodiment.
- Each web section la, 1b consists of three zigzag halved broad flat steels as web plates, to which the upper chord profiles 2a and 2b are welded. They are concreted into the ceiling slabs 3a and 3b in the workshop.
- the continuous lower flange 4 is fastened to the support end supports (e.g. supports) and raised in the middle of the field by assembly supports.
- the web plates la, b concreted in are inserted between the lower flange profiles 4a, b and connected to them by means of non-slip screw connection 5. Either holes or slots open at the bottom can be provided for the HV bolts in the multi-wall sheets. Tolerances across the composite girder plane are compensated by forcing the flexible web plates 1 in the direction of escape of the lower flange 4.
- the outer multi-wall panels are spread downwards during assembly and the lower flange profiles are pressed apart. Spacers 6 serve this purpose.
- Additional profiles 7 are screwed to both sides of a butt joint in the lower flange, or other reinforcements in order to transmit the transverse force which arises at the joint.
- the pressure force transmission of the upper chord at the abutment of the ceiling slabs 3a, 3b is produced by an inserted steel piece 8 and the concrete filling 9.
- Modifications to the construction shown are obvious for the person skilled in the art. Instead of a lower flange made of two L-profiles, a single T-profile can also be used, the multi-wall sheets then lying on the outside. Conversely, all of the multi-wall sheets can also lie close together so that they can be inserted together between L-profiles of the lower flange, the distance between the two lower flange profiles is then correspondingly larger.
