Definitions

  • Such a plate-shaped prefabricated part is known from DE-PS 803 427 and that in these previously known ceiling panels the recess is designed as a frontal offset, i.e. in the support area this known prefabricated part of the upper flange is entirely absent. This has various disadvantages.
  • the aim of the invention is to remedy these disadvantages and to design the precast reinforced concrete part in which a high load-bearing capacity can be guaranteed even before the in-situ concrete is applied and in which there is a good bond between the in-situ concrete and the precast reinforced concrete parts.
  • the recesses in the prefabricated reinforced concrete part are designed as individual, longitudinal channels that open at the end faces.
  • the weakening of the top chord of the prefabricated parts by these channels is only minor, but the bond between the reinforcements of the top chord, the in-situ concrete of the ceiling and the prefabricated concrete slabs is greatly improved.
  • the reinforcements of the top chord in the support area find an excellent hold in the channels and the in-situ concrete placed between the precast concrete elements lying opposite each other is advantageously interlocked with these precast elements.
  • the bond effect in the support area is also greatly improved if - according to a further feature of the invention - the precast concrete part has longitudinal cavities, some of which are open at least in some areas upwards, in order to close the channels intended to accommodate the longitudinal reinforcements of the upper flange that can be inserted as required form.
  • transverse or stirrup reinforcements embedded therein can be exposed within the channels and form supports for the longitudinal reinforcements of the upper chord to be inserted, which considerably simplifies the laying of these longitudinal reinforcements.
  • the invention also extends to a ceiling made of precast concrete parts according to the invention.
  • the channels intended for receiving the longitudinal reinforcements of the top chord are aligned on the end faces of the prefabricated parts of adjacent slab fields, and in these channels longitudinal reinforcements are inserted across the supports of these slab fields and in one the recesses and, if necessary the gaps between the end faces of the prefabricated parts or their cavities partially filling in-situ concrete.
  • the usual longitudinal reinforcements 2 are embedded in the area of the underside, that is to say the lower chord, the ends 2 'of which protrude from the end faces of the precast concrete elements 1 into hooks. Furthermore, these precast concrete elements 1 are interspersed with circularly profiled cavities 3, which are provided at regular intervals from each other and run parallel to one another in the longitudinal direction of the precast concrete element 1. On their slightly sloping flanks, these precast concrete parts 1 have deposits 4, from which the transverse reinforcements 5 of the lower chord protrude with upwardly projecting ends 5 '.
  • Cross reinforcements 6, which could also be designed as stirrup reinforcements, are likewise embedded in the upper chord of the prefabricated parts 1. Furthermore, in the area of the top of the prefabricated parts 1, longitudinal recesses 7 opening at the end faces are provided, which extend only over end regions with the partial length 1 ′ over the top of the prefabricated concrete part 1 with the total length 1. In these areas, the cavities 3 of the prefabricated concrete parts 1 which are respectively assigned to the recesses 7 below are partially open at the top in order to form the recesses 7 themselves, which are intended for the insertion of longitudinal reinforcements 8 as required.
  • These longitudinal reinforcements 8 of the top chord of the precast concrete parts 1 then run across the common supports 9 of adjacent ceiling panels, i.e. where the negative supporting moments of the continuous beam occur when the adjacent ceiling panels are monolithically connected to one another.
  • the distance a / 2 between the longitudinal edges of the precast concrete part 1 and the recesses 7 running from these longitudinal edges advantageously corresponds to half the uniform distance a of these recesses 7 from one another, so that the alignment of opposing recesses 7 of adjacent ceiling fields is always ensured, irrespective of whether the laying of the precast concrete parts 1 facing each other is carried out fully on joint or joint on joint.
  • a monolithic structure is formed after the placing of in-situ concrete in the recesses 7 and in the space 10 between the end faces of the prefabricated parts 1, which is to be addressed as a real continuous beam with regard to its static properties and thus a better, more economical use of the therein Reinforcement contained, thus a more economical use of the steel.
  • the usable height of the precast concrete elements 1 can also be reduced as a result of the maximum and minimum bending moments reduced by the continuous effect.
