Definitions

  • the invention relates to a rib ceiling element according to the preamble of claim 1.
  • An element of this type is known from DE-PS 1 928 656.
  • the shells In its grating consisting of longitudinal and transverse struts, the shells are anchored with their edges in such a way that they cover the grating openings or, in other words, that the longitudinal and transverse webs of the grating represent the connection between the individual shells.
  • Deep channels remain above the struts between the walls of mutually adjacent shells, which widen conically upwards, that is to say towards the bottom of the shells, since the shell walls are inclined. These channels are also filled in when the in-situ concrete layer is applied. For static reasons, the in-situ concrete layer must be at least 3 cm thick above the shell bottoms.
  • the known elements are light and can be brought to the installation site with normal lifting equipment.
  • the object of the invention is to design a rib element of the type described at the outset in such a way that it can be produced economically and can be attached to the installation site.
  • the element is therefore more economical and easier to manufacture. Furthermore, its inherent stability increases significantly: the thickness of the shell walls is added to the width of the web cast in between for the strength calculation. The significantly increased inherent rigidity of the elements allows support-free areas when laying, which are a multiple of the previously possible distances between supports. This enables faster and more economical laying. Furthermore, the space under the element is more accessible.
  • a height of the shells of 16 to 18 cm has proven to be advantageous.
  • the shells advantageously have a thickness of 2 cm. This means that the top of the trays can be walked on if necessary.
  • a fiber-reinforced base plate can be cast onto the grating.
  • the grating can be roughened on its underside, which makes the connection with the base plate even more intimate.
  • FIGS. 1 and 2 schematically show a partially finished rib ceiling element, designated as a whole by 1. It consists of shells 2 and a grating, designated as a whole by 3. This consists of longitudinal webs 3a and transverse webs 3b. The webs completely fill the space between the shells 2 up to their surface side.
  • shells and grating are made in one piece.
  • the thickness g of the webs on their narrowest, lower side is 15 cm.
  • Fig. 2 it is indicated schematically how the rib ceiling element 1 rests on a support 4 during assembly in the region of a narrow side. Furthermore, a fragment of a longitudinal reinforcement 5 is shown there, as is arranged in the longitudinal webs 3a, which project above it. In Fig. 1, the longitudinal movement. stanchions 5 indicated by dash-dotted lines.
  • Fig. 3 shows schematically the production of a Fig. 1 and 2 corresponding rib ceiling element 1, shown here in cross section.
  • Fixed formwork bodies 7, which correspond to the hollow shape of the shells 2, are arranged on a vibrating table 6. Their distance from one another corresponds to the width of the longitudinal webs 3a provided plus the wall thickness of the shells 2. The structure is delimited laterally by formwork 8.
  • Fig. 4 shows a cross section through a rib ceiling element 1 ', in which the shells 2 were individually prefabricated and connected to them and to one another by casting in the manufacture of the grating 3.
  • the longitudinal reinforcements 5 are shown. Additional elements laid next to it are indicated on both sides of the element 1 '.
  • a small part of an in-situ concrete layer 9 is also indicated, which is applied when the ceiling is finished using the ribbed ceiling element 1 'and which receives parts of the reinforcement 5 projecting over the element.
  • FIG. 5 Another embodiment of a rib ceiling element 1 "is shown in FIG. 5 in a diagram corresponding to FIG. 4 position pictured.
  • the underside 10 of the grating ie the longitudinal webs 3'a and the transverse webs not visible in FIG. 5, is roughened.
  • a bottom plate 11 made of fiber-reinforced concrete is cast onto the underside 10. It extends over the entire rib ceiling element, ie also over the openings of the shells 2.
  • the right part of FIG. 5 shows the joint between two adjacent rib ceiling elements 11 , which have other edge regions 13 and 14 which are specially designed for connection.
  • the edge area 13 is designed as a step. It has essentially the shape and size of a longitudinal web 3'a with the difference that it has a step-shaped support recess 15 on the upper longitudinal edge.
  • the edge region 14 is designed as a supporting edge. Its height, from the surface side 2a downwards, corresponds to the height of the step-shaped support recess.
  • the length of the supporting edge 14 consists alternately of shell walls ending at this height and correspondingly filled intermediate spaces in the area of the respective transverse webs between the shells.
  • the step-shaped support recess 15 is so wide that a connection joint 16 to be filled with in-situ concrete remains next to its vertical wall.
  • Fig. 6 shows the use of rib ceiling elements 1, shown in cross section, for the production of a particularly thick ceiling.
  • additional shell-shaped displacement bodies 12 with dimensions corresponding approximately to the shells 2 have been placed on them.
  • Fig. 6 'displacement body 12 to 12c of different nature and height are shown:
  • the displacement body 12, relatively low, consists of a plastic body, the displacement body 12a is a concrete shell, the displacement body 12b is "solid" from a ge foamed material and the displacement body 12c made of lightweight panels.
  • a rib ceiling element can vary. Reinforcements can also be provided in the crossbars. In the production of the ceiling with ribbed ceiling elements according to the invention, an additional, flat reinforcement is provided in the in-situ concrete, which is not shown in the figures.
