Definitions

  • the invention relates to a supporting element for constructing ceilings and/or floors of buildings according to the preamble of claim 1.
  • load-bearing elements are placed together and connected to the respective vertical building structure.
  • connecting the load-bearing elements to one another is only possible if the functional element is not yet incorporated into the load-bearing element.
  • Functional elements include, for example, insulation material, soundproofing materials, installations, and the like.
  • the functional element can only be inserted once the load-bearing elements are connected to one another. Since the load-bearing elements can only be fitted with the respective functional element after they have been connected to one another and to the building structure, this procedure is very complex and laborious.
  • the invention is based on the object of designing the generic support element in such a way that it can be used to easily connect the ceilings/floors to the building structure.
  • the support element according to the invention has the assembly opening located in the projecting edge of the support element. This makes the assembly opening accessible for assembly even when the support element is delivered ready for installation to the installation site. It is then only necessary to connect the prefabricated and ready-to-install support elements to each other and to the The trough-shaped design allows for complete prefabrication of the supporting element in the workshop.
  • the support element can also be completely assembled at the installation site.
  • the supporting element advantageously has a frame made of plug-in parts that can be easily assembled. After the plug-in process, the frame parts can be easily and firmly connected to one another.
  • the frame is formed by profile rails. This allows the profile rails to be designed in such a way that they are adapted to the specific application of the supporting element.
  • profile rails are particularly cost-effective and easy to manufacture when made from roll-formed steel profiles.
  • the profile rails can also be made from aluminum or wood profiles with appropriate profiling.
  • the profile rails are connected at their ends by connectors.
  • the connectors first plug the profile rails together and then firmly connect them, preferably using screw connections.
  • the frame of the supporting element can be easily manufactured in this way.
  • the connecting pieces are advantageously metal profile pieces.
  • Such metal profile pieces are preferably angle pieces with legs that are at an angle, preferably at right angles to each other. Since the frame of the supporting element usually has a square, particularly rectangular, outline, the legs of the angle pieces are correspondingly at right angles to each other. They are attached to the inside of the profile rails, which are at the same angle to each other.
  • the metal profile pieces preferably the angle pieces, are arranged within the frame and thus the supporting element, they are protected after installation so that there is no risk of them being damaged or even destroyed.
  • the profile rails are preferably C-shaped. They have a web connecting two transversely projecting legs with angled edge sections running toward each other. This profile shape gives the profile rails high strength.
  • the profile rails form the longitudinal and transverse rails of the frame. Therefore, different profile rails are not required for the different sides of the frame. This greatly contributes to cost-effective production and easy assembly of the support element in the workshop.
  • the framework is advantageously provided with stiffening.
  • This stiffening advantageously comprises at least one longitudinal stiffener, which connects opposing frame sides to each other.
  • the term "longitudinal stiffener” is primarily associated with rectangular frames that have a longitudinal extension. However, a longitudinal stiffener can also be understood as a stiffener that connects two opposing frame sides of a square frame.
  • the stiffening of the frame advantageously also comprises at least one transverse stiffening.
  • this transverse stiffener connects the longitudinal stiffener to opposite frame sides.
  • the transverse stiffener extends perpendicular to the longitudinal stiffener and thus also perpendicular to the corresponding frame sides.
  • a particularly advantageous, easy-to-create longitudinal reinforcement is achieved when it is formed by two adjacent profile rails. These are also advantageously C-shaped.
  • the two rails are placed together with their webs adjacent to each other, so that their legs run opposite each other from the webs. With the two adjacent profile rails, the longitudinal reinforcement and thus the frame are highly rigid.
  • a particularly advantageous feature contributing to simple assembly is that the profile rails of the longitudinal reinforcement are attached at their ends to the frame sides lying transversely to them by angled connecting elements.
  • These connecting elements are advantageously housed in a protected manner within the frame, with the connecting elements having angled, preferably perpendicular, legs that are attached to the inside of the transverse frame sides and to the opposite outer sides of the profile rails of the longitudinal reinforcement.
  • the connecting elements are preferably metal profile pieces.
  • the simple assembly of the supporting element according to the invention is further advantageously facilitated by the fact that the transverse reinforcement is formed by profile rails, the ends of which are pushed onto connecting pieces on the longitudinal reinforcement and on the opposite frame sides and are then firmly connected to these connecting pieces.
  • the connecting pieces which are advantageously metal profile pieces, have a contour shape such that the profile rails of the transverse reinforcement can be pushed onto them in such a way that they are firmly attached to the connecting pieces. Then the profile rails can be attached to the connecting pieces easily and reliably, preferably using a screw connection.
  • Another advantageous design involves stiffening the structure with a cross-braced cable tensioning system. This requires minimal installation space, is inexpensive to purchase, and is easy to install.
  • the cross-bracing cable bracing comprises at least two intersecting cables, the ends of which are fastened to the frame within the supporting element.
  • the ropes can be made in one piece, but can also consist of at least two rope sections.
  • the cables can extend the entire length of the supporting element. Depending on the length of the supporting element, it is also possible for the supporting element to have two or more cross-braced cable bracings.
  • coupling elements are advantageously arranged on those frame parts via which the supporting element is to be connected to the vertical building structure.
  • the coupling element is an angle piece having two legs positioned at an angle, preferably at right angles to each other.
  • One leg is attached, preferably screwed, to the outside of the corresponding frame part.
  • the other leg then projects transversely from the frame part to the outside and serves as the connection to the Building structure.
  • a corresponding number of coupling elements can be provided to ensure reliable attachment of the load-bearing element to the building structure.
  • the edge of the frame that protrudes beyond the top and/or bottom is provided with at least one support for at least one cover part.
  • This cover part is preferably plate-shaped and rests on the support.
  • the cover part covers the functional element located in the frame from the outside and is preferably screwed to the support.
  • the support for the cover part is particularly advantageously formed by a profile section of the profile rails. If the profile rails have a C-shaped configuration, the support is advantageously formed by angled free ends of the edge sections of these profile rails. In this case, the support advantageously extends over the entire length of the profile rails, allowing the cover part to be securely attached to the frame along its circumference.
  • the support for the cover part is arranged in the area below the installation opening, so that despite the cover part being above the installation opening, a simple connection of adjacent supporting elements to create the ceiling and/or floors is possible without any problems.
  • a further advantageous design is achieved when parts of building installations are housed in the supporting element.
  • building installations include, for example, heating and cooling systems, cooling and heating pipes, electrical and IT cabling, water supply and sewage pipes, sprinkler systems, and the like.
  • the mounting opening of the support element advantageously serves to connect adjacent support elements by means of connecting elements.
  • the supporting elements lie against each other with their corresponding frame sides and are firmly held together by the connecting elements.
  • the connecting element has a screw sleeve provided with a transversely projecting stop at one end, into which a screw spindle can be screwed.
  • An angle screwdriver is advantageously used for this purpose.
  • the support elements described below each have a supporting frame, which advantageously consists of roll-formed, preferably galvanized steel profiles. These are bolted together using efficiently manufactured connecting brackets.
  • the supporting frame is advantageously designed so that at least one support plate can be attached to the top and bottom.
  • Support plates are attached to the supporting framework at the top and bottom to define a ceiling cavity.
  • the upper support plate serves as Support for a floor structure to be installed on site, which may include, for example, impact sound insulation, screed, and floor covering.
  • the lower support plate provides support for cavity insulation and is used to attach installations and supply lines integrated into the supporting elements.
  • the support plates can also take on the function of a static brace.
  • the cavity between the support plates and the steel profile parts is advantageously completely filled with an insulating material.
  • This insulating material can be blown into the cavities.
  • Foam material can also be used as an insulating material, which, when expanded, completely fills the cavities easily and quickly.
  • the support elements are designed so that they can be easily connected to one another at the installation site, particularly by means of a screw connection.
  • An angle screwdriver is advantageously used for this purpose. This avoids the need for individual assembly of the support element on site.
  • Heating and cooling ceiling systems can be pre-assembled into the supporting element in the factory.
  • the lower ceiling cladding and the floor structure, such as screed, are produced on site in the conventional manner.
  • the supporting element is largely manufactured as a frame element prefabricated in the workshop so that it can be very quickly assembled, suspended and coupled at the construction site.
  • the supporting element has a load-bearing function and can be easily suspended or attached to a vertical building structure in a manner to be described below.
  • the load-bearing elements By connecting the ceiling modules in a rapid assembly method, the load-bearing elements allow a ceiling-to-surface structure to be created, forming a stiffening load-bearing plate capable of absorbing all loads.
  • loads include vertical loads, such as dead weight, traffic and snow loads, horizontal loads, primarily wind loads, and special loads, such as those that occur during earthquakes.
  • the stiffening effect of the surface structure formed from the load-bearing elements also ensures that the horizontal forces that occur are specifically transferred to the vertical load-bearing structure of the building, which means that the deformations of the building are extremely small.
  • FIG. 1 A building is shown schematically. It has upright posts 1 that are connected to each other at the top and bottom by horizontal crossbeams 2.
  • the posts 1 advantageously consist of sections 1a that sit one on top of the other and are firmly connected to each other.
  • the posts 1 and the crossbeams 2 form facade load-bearing elements 3 that are arranged above and next to each other.
  • Each facade load-bearing element 3 has fields 4 that are delimited by the posts 1 and the crossbeams 2.
  • the fields 4 serve to accommodate building elements such as glass windows, wall elements, and the like.
  • Bracing modules (not shown) can be accommodated in all fields 4 or in individual fields. They are provided depending on the design of the supporting structure so that it has the desired stability.
  • the building has a ceiling 5 and two floors 6, 7, each of which defines a storey and each has load-bearing elements 8.
  • the supporting elements 8 of the ceiling 5 are fastened with their narrow sides to the upper ends of the sections of the posts 1 of the facade supporting elements 3 in a manner to be described below.
  • the supporting elements 8 of the floors 6, 7 are fastened, in a manner to be described below, to the upper ends of post sections 1a arranged one above the other, which form the posts.
  • Fig. 2 shows an embodiment of support elements 8, which are placed together with their longitudinal sides and, when installed in the building, form components of the ceiling 5 or the floor 6, 7.
  • the support elements 8, which are placed together with their longitudinal sides, are advantageously screwed together so that they can be separated from each other if necessary, for example if one of the support elements 8 is damaged and needs to be replaced or repaired.
  • the majority of the support elements 8 are of identical design. In the central region, the support elements 8 are shorter because the component formed from the support elements 8 is provided with an opening 9 at the edge. This opening has a rectangular outline.
  • the built-in part formed from the supporting elements 8 can also be provided without such an opening 9 or with further openings 9, depending on the desired design of the built-in part.
  • the longitudinal rails 10 have a C-profile ( Fig. 10 and 25 to 28 ).
