Definitions

  • the invention relates to a multifunctional component according to the preamble of claim 1.
  • the use of prefabricated parts has proven itself in civil engineering, particularly when erecting buildings. Compared to conventional construction, these offer a cost advantage due to series production and less time required. However, the trend towards individual construction prevents the production of large series of standardized components, which means that the cost advantage of series production is partially eliminated. Equipping buildings with energy-saving heating, ventilation and air-conditioning systems also makes it more difficult to standardize prefabricated components.
  • the object of the invention is to provide an ultimate component which can be used in buildings with the same basic concept, in particular in the floor, wall, floor and roof areas of buildings, and the integration of heating, ventilation and air-conditioning equipment enables.
  • the multifunctional component according to the invention combines a large number of properties which, in their entirety and mutual coordination, enable universal applications.
  • the component according to the invention can be used as lost formwork in the manufacture of floor slabs.
  • the plate-shaped base part and the side switching parts form a closed trough, which can be filled on site with poured concrete or can also be manufactured as a prefabricated part in the factory or on the construction site. By eliminating the need to remove formwork, working time and costs are saved.
  • the pimple-like islands of the base partly ensure that there is an intimate connection between the component and the concrete layer.
  • the heat-insulating material from which the multifunctional component is made ensures good thermal insulation between the storeys, avoids thermal bridges between the outer parts of the building and the floor ceiling and additionally results in highly effective footfall sound insulation.
  • the costly application of floating screed can therefore be dispensed with.
  • the knob-like islands arranged on the plate-shaped base part are particularly suitable for accommodating pipes, cables or lines for building installations in their interstices and thereby fixing them against displacement and protecting them from damage from the free, open side.
  • These aspects play an essential role in the shell construction phase, in which it is inevitable that tradesmen have to enter the surfaces with the pipes, cables or lines still open, or that construction materials are deposited and stored on these surfaces.
  • a grid is specified by the knob-like islands, based on which particularly fast and the installation can be carried out easily, since time-consuming measuring and marking work can be omitted. Furthermore, a quick check by comparison with planning documents is possible.
  • the nub-like islands take over the task of the spacers which are otherwise customary in conventional formwork, so that material and labor savings can also be achieved in this regard.
  • the base part is composed of a plurality of base plates which are connected to one another by tongue and groove, and that the formwork parts are also formed by a plurality of formwork elements arranged in a row.
  • the formwork element is preferably designed as an angle piece, the legs of which form a right angle.
  • a groove is arranged on one long side of the leg of the formwork element parallel to the base part and a tongue is arranged on the other long side.
  • the formwork elements forming the formwork parts are connected to the base plates forming the base part by tongue and groove.
  • This construction enables the production of floor ceilings and walls.
  • the base part is delimited all around with suspension parts, so that a border is formed for the concrete to be filled.
  • the Ver ⁇ connection by tongue and groove connection provides a dense Ver ⁇ so that effet fürtre ⁇ during the filling of flowable materials, such as polymer concrete or concrete, no material can th, as often occurs in the konvetionellen casing •. This eliminates the time-consuming removal of burrs after formwork removal when pouring floor ceilings or walls on the spot.
  • the tongue and groove connection also enables the compensation of slight tolerances without losing the sealing effect.
  • the base plates and formwork elements can have the same length or integer multiples. In the latter case, there is the possibility of arranging the base plates and formwork elements in mutual offset and only allowing two corners to meet each other, which are opposed by a continuous tongue or groove on the other side. In this way, better stability and surface uniformity on the back can be achieved.
  • openings are provided in the legs of the formwork element parallel to the base part. These openings are suitably adapted in their contours and arrangement to the islands on the surface of the base part.
  • the formwork elements forming the formwork parts can be connected to the base plates forming the base part by placing them on the base plate, the openings receiving the islands.
  • This version is suitable for the production of roof rafters, in which the space between two parallel formwork elements is filled with concrete. The stability of the roof is then ensured during assembly by the continuous base plates. In addition, a greater overall height than that of the aforementioned arrangement is achieved in this way, which facilitates the accommodation of pipelines with a large cross-section and additionally increases the bending rigidity of the rafters formed in this way.
  • the islands and openings are square-like, but the exact cuboid shape differs in that the corners are rounded and the edges are curved inwards.
  • the base area described is advantageous both in the production of the molds for the base plates and formwork elements and in the assembly of pipelines and the assembly of formwork elements on base plates.
  • the base area described is advantageous both in the production of the molds for the base plates and formwork elements and in the assembly of pipelines and the assembly of formwork elements on base plates.
  • constriction at the head ends is prevented by the bending radius being too narrow, and finally the mutual pressure of the walls of the islands on the walls of the openings when assembling elements and base plates evenly distributed. If there are inaccuracies in the match, in particular larger islands than openings, the edges of the islands can specifically bend inwards and adapt better to the opening while reducing their cross-sectional area.
  • a further embodiment provides that on the underside of the leg of the formwork element that is parallel to the base part, a longitudinally extending depression is provided, in which a plain bearing is arranged.
  • this side faces inwards in most cases, it can be papered directly without complex adjustment work or can be provided with a visual plaster or paneling according to design considerations.
  • Another embodiment provides that the side opposite the side of the base part with the knob-like islands is provided with depressions for receiving pipelines.
  • These pipelines can then be accommodated as heat exchangers in the wall and ceiling area and thus additionally support underfloor heating which may be present in the floor ceiling or can also effect effective room cooling in warm areas.
  • the uniform supply of heat or removal made possible in this way creates a particularly comfortable room climate.
  • only slight flow temperature differences are required, so that the operation of a heat pump is economical even at extreme outside temperatures.
  • pipelines are integrally embedded directly below the surface of the flat side, the aforementioned advantageous properties, namely the ability to paper the wall and ceiling without preparatory measures, can also be exploited in this embodiment.
  • pipelines and / or cables are arranged in the interspaces of the base part between the knob-like islands.
  • a composite layer with permanently elastic, temperature-resistant, heat-conducting and water-impermeable properties is applied to the base part between the formwork parts. This completely encloses the pipelines and cables.
  • the gaps between the nub-like islands create channels that protect the pipes and cables against lateral shifting and also protect them from above, for example during the shell construction phase. Since the nub-like islands and the gaps are arranged in a uniform grid, it is easy even for the layperson to lay the pipes or cables exactly on the basis of a plan. By counting the islands otherwise necessary marking work can be omitted.
  • the properties of the composite layer applied to the pipelines and cables ensure that the pipelines or cables can expand or shrink even when subjected to strong heating or cooling, without stresses resulting in damage to the rigid concrete applied later.
  • the heat-conducting properties ensure that a good transition to the concrete layer above or, if appropriate, a reinforcement incorporated therein is achieved and that the pipes or cables are well heat-balanced with one another. In this way it is even possible to carry out a heat exchange between pipelines of different heating or cooling agents.
  • the base part With the pipelines and their composite layer, the base part already has such a strength that the statics for the application of the later concrete layer is roughly comparable to that of a conventional wooden formwork.
  • the effort required for formwork supports and supports is therefore not increased by the use of the component according to the invention.
  • This structure uses the concrete layer both for load-bearing purposes and as screed for a floor covering.
  • This structure leads to a substantially smaller ceiling thickness and thus enables a larger clear ceiling height per floor for the same building height.
  • this structure offers integrated thermal insulation through the base part, as well as protection against cold or thermal bridges through the formwork parts and, due to the fact that the formwork parts rest on the walls, good impact sound insulation.
  • the component according to the invention is designed as a floor slab, the formwork parts being arranged laterally next to the base part.
  • the floor slab can be cast in place using the base part and the formwork parts as lost formwork. It offers the possibility of laying pipes and cables according to the individual requirements and connecting them to other installations. Another possibility is to prefabricate the floor ceiling in transportable parts at the construction site, it also being possible to lay the pipes individually, and then to place the components on the walls. Finally, the components can be mass-produced as standard parts, transported to the construction site and then installed like the parts prefabricated on the construction site. The considerably lower weight compared to conventional floor ceilings enables relatively large floor ceilings to be used in a state that is finished except for the floor covering.
  • the pipelines and / or the cables serve as heat exchangers and are laid in a neandering manner in the spaces between the knob-like islands.
  • the pipelines and cables are routed around the islands at the head ends and are particularly defined.
  • the pipes or cables are laid bifilar.
  • the pipelines or cables can be laid at different mutual distances and / or have a different cross section.
  • the distance in the edge area of a floor ceiling or to outer walls can be chosen to be smaller than in the inner area.
  • the pipes lying in the outer region can be provided with a larger cross-section than the pipes laid in the inner region.
  • a construction suitable for other purposes provides that in the spaces between the base part between the knob-like ones Islands of pipelines and / or cables are arranged and that a composite layer of permanently elastic, heat-insulating material is applied to the base part between the formwork parts.
  • a preferred layer can then be be provided with reinforcement concrete layer.
  • a component according to this embodiment is suitable e.g. as an upper end ceiling in flat roof buildings or as a wall element.
  • a concrete layer preferably provided with reinforcements, is applied to the base part between the formwork parts.
  • the component is expressly designed as a wall, the formwork parts being arranged laterally next to the base part.
  • the component is expediently set up so that the base part points inwards, if it is external walls. Even in its design as a wall, the component can be manufactured on site according to the invention. In this case, however, additional formwork to the open side is required, so that it seems more appropriate to prefabricate the component in a horizontal state at the construction site or in the factory.
  • the structural element is designed as a rafters, the formwork parts being arranged on the base part in pairs over the roof area and the base plates extending along the entire roof area.
  • This structure creates the prerequisite for the rafters to be able to take on additional tasks compared to conventional wooden rafters.
  • the pipes housed in the rafters can thus withdraw heat from the surroundings in cold weather, which are then supplied to the heat exchangers installed in the interior for heating the room will or in warm weather radiate heat to the environment, which is absorbed from the interior by the heat exchangers installed inside the building.
  • the weight is only slightly greater in comparison to conventional roof constructions, because it is essentially determined by the weight of the roof tiles. The difference in weight would be reduced even further if the conventional roof were additionally provided with solar collectors in order to create properties comparable to those of the structural element according to the invention.
  • the arrangement of the formwork parts on the base part achieves a higher overall height for the rafters, so that the bending stiffness increases and a larger number of pipes can be accommodated with a smaller width.
  • the base plates extending along the entire roof surface enable, as already mentioned at other points, the arrangement of pipelines as heat exchangers on the inward-facing surface and the covering or application of a visual plaster or: paneling. At the same time, the base plates also serve here for insulation. Opposite the conventional tional design, in which the space between the rafters must be filled separately with insulating material, this solution offers the advantage that slots that would allow the entry of drafts can be safely avoided.
  • the pipelines are also laid in a meandering manner in the component serving as rafters. However, they can also be arranged above the knob-shaped islands in order to obtain a smaller contact resistance to the surroundings.
  • ventilation pipelines running parallel to the base part and the formwork parts are provided, which are thermally closely coupled to the pipelines.
  • These ventilation pipelines preferably have a substantially larger cross section than the other pipelines.
  • the arrangement and design of the ventilation pipelines described enables forced ventilation of the interior as well as the drain lines and a possible fume extraction.
  • the heat present in the exhaust air can be caused by the large surface area of the Ventilation pipelines give off their heat to the pipelines that surround them or that run in parallel as heat exchangers. The heat contained in the exhaust air is thus partially used again for space heating.
  • the forced ventilation which contributes significantly to an improvement in the indoor climate, can thus be used without the disadvantage of an excessive increase in heating costs.
  • the ventilation pipes take over in connection with the surrounding composite layer e.g. made of polymer cement or concrete, the function of a reinforcement and significantly reduce the weight of the rafters determined by the concrete layer due to the cavity enclosed by them.
