Definitions

  • the invention relates to a prefabricated ceiling element as a prefabricated component.
  • the invention relates to a reinforced concrete ceiling, the several such ceiling elements contains.
  • the ceiling elements are in a manufacturing company for prefabricated elements produced and then transported to a construction site, where they are in a Buildings are used, preferably put together to a basement ceiling become.
  • the invention further relates to a method for producing the ceiling element as a prefabricated component.
  • Reinforced concrete ceilings are based on building regulations, standards and technical Rules made significant demands. The most important are one high load-bearing capacity according to structural requirements, high fire resistance, Sound insulation measures to suppress airborne noise and Impact sound and high thermal insulation. More requirements, the more relate to production, assembly and economic aspects, are the production of the reinforced concrete ceiling in an economical production process and a low use of materials. Furthermore, in the event that prefabricated Ceiling elements are used as prefabricated components, the transport weight of the ceiling elements to be low to these ceiling elements from the manufacturing company to be able to be transported economically to the construction site.
  • the ceiling elements should be technically simple and economical on the construction site Allow installation to a reinforced concrete ceiling. Furthermore, the Ceiling elements can be used flexibly for different types of buildings his.
  • thermal insulation is one of the most important Become criteria for ceiling systems.
  • the general goal is that in the Thermal insulation ordinance to exceed the specified thermal insulation values. Around To achieve this becomes a high technical level with previous ceiling systems Effort. This effort is mainly incurred on the construction site and contradicts thus the technical trend towards factory prefabrication. Thermal protection Local measures also represent a significant economic Disadvantage.
  • the lattice girders serve both as reinforcement in structural engineering Sense as well as a spacer between the two concrete slices.
  • the Lattice girders therefore have a double function.
  • the lattice girders are made accordingly designed to meet structural requirements. These lattice girders serve as Truss girders and serve to transmit thrust to the middle and End support of the ceiling element.
  • the lattice girders form small thermal bridges between the two washers, however, is the cross section of the steel elements the lattice girder is relatively small, so that the heat flow is also relatively small.
  • the cavity that results between the two disks is already in the Production foamed with polyurethane foam.
  • the cured polyurethane layer supports the structural function of the lattice girders and the concrete panels.
  • Such production can be advantageous on a circulating pallet system take place economically in production.
  • the required thermal insulation can be adjusted via the thickness of the polyurethane layer.
  • a relatively light, prefabricated ceiling construction is achieved, which is only slight Has thermal bridges. This can save a significant amount of energy can be achieved.
  • the ceiling elements can be large-format as prefabricated components getting produced. As a result, they can be opened relatively easily and quickly the construction site. Elaborate concreting work is thus kept to a minimum reduced.
  • a reinforced concrete ceiling is also specified, the several contains such ceiling elements as prefabricated components.
  • a reinforced concrete ceiling can be used variably because of the overall height and the design of the lattice girders can be chosen according to the structural requirements.
  • the large-format ceiling elements have due to their manufacturing method in the production plant good flatness. This flatness is for further expansion of the building is of great advantage because of the usual leveling can be dispensed with.
  • the invention relates to a method for producing a ceiling element as a prefabricated component according to the features of claim 11.
  • a second is applied to the cured polyurethane foam Concrete disc concreted, the end sections of those protruding from the polyurethane foam Lattice girders.
  • the cured polyurethane foam serves So in the production as a carrier for the initially liquid concrete layer second concrete disc.
  • the cured polyurethane foam sufficient structural stability for that of polyurethane foam Enclosed lattice girder forms, so that for the entire ceiling element sufficient ability to absorb horizontal pulling and pushing forces given is.
  • the surface just subtracted so that this surface as the outer surface of the ceiling element can be easily treated further.
  • FIG. 1 shows schematically the structure of a prefabricated ceiling element as Prefabricated component.
  • the ceiling element comprises a lower disk 10 made of reinforced concrete and an upper plate 12 made of reinforced concrete.
  • each disc 10, 12 there are end sections concreted by lattice girders 14, i.e. the longitudinal bars 15a and cross bars 15b and associated welded strut nodes 15c are completely embedded in concrete.
  • Both the lower disk 10 and the upper disk 12 are through Round bars arranged crosswise, some of which are designated 15 by way of example are reinforced.
  • prefabricated reinforcing steel mesh can be used as reinforcement be provided.
  • In the cavity 16 between the two disks 10, 12 is filled with polyurethane foam during the production, which hardens.
  • a total thickness D of 200 to 300 mm for an application example as a basement ceiling element.
  • Typical values for the length L are ⁇ 12 m and for the width B ⁇ 3m.
  • FIG. 2 shows a cross section through the ceiling element. Same parts are called the same. Between the lower disc 10 and the upper disc 12 the cavity 16 is completely filled with polyurethane. The lattice girders 14 form thermal bridges between the two panes 10, 12. Because of the Small cross sections of the lattice girder 14 is the heat flow between the two Disks 10, 12 relatively small, so that the polyurethane layer as a heat insulating Layer comes into effect. In this way, high thermal insulation with relatively low weight and simple construction of the ceiling element reached. It can be clearly seen in FIG. 2 that both the lower disk 10 as well as the upper disc 12 is reinforced by round steels 15, which act as longitudinal reinforcement and as transverse reinforcement the structural requirements for a Help meet blanket.
  • Figure 3 shows a cross section through the ceiling element.
  • the polyurethane layer has a recess in the area 20.
  • this recess 20 there is steel reinforcement introduced with longitudinal rods 22 in the longitudinal direction.
  • the density of the lattice girders 14 is also increased. That way achieved a static increase in the ceiling load capacity in this area 20.
  • Figure 4 shows a longitudinal section through the ceiling element.
  • a transverse reinforcement with cross bars 24 is introduced in the area of the recess 20. This Cross reinforcement increases the load-bearing capacity in the transverse direction.
  • Figure 5 shows the complete structure of a reinforced concrete ceiling, the two ceiling elements 30, 32 includes.
  • the reinforced concrete ceiling is a basement ceiling and sits on Edges on outer walls, e.g. the wall 34 on.
  • Around the circumference of the reinforced concrete ceiling a circumferential ring belt reinforcement 36 is attached.
  • At butt sections is a connecting element between the two ceiling elements 30, 32 38 arranged.
  • On a longitudinal joint surface 40 between the ceiling elements 30, 32, a further connecting element 42 is provided, which the ceiling elements 30, 32 connects to one another in the direction of the longitudinal axis.
