Definitions
- the invention also relates to a pressure-resistant, heat-insulating construction panel made of an extruded profile of an at least double web plate multiple with parallel to the outer profile side surfaces along continuously extending, cavities limiting stiffening webs.
- the invention further relates to a pressure-resistant, heat-insulating construction plate, consisting of a plastic housing comprising at least one inner cavity with a plurality of stiffening webs arranged in the inner cavity for receiving the pressure load.
- a building construction plate for hail impact-resistant light panels of translucent plastic material is known for example from DE 30 48 695 A1, in which cavities are arranged perpendicularly or obliquely to the extruded profile rectilinear stiffening webs, which also in the formation of the light plates as a web multiple plate straight between the continue parallel broad outer surfaces.
- the invention has for its object to provide a pressure-resistant, heat-insulating construction plate, on the one hand has a low heat transfer coefficient and on the other hand, a high compressive strength.
- this object is achieved in that the adjacent cavities of the web multiple plate and the webs delimiting them are formed by a plurality of distance-determining hollow profiles, which are arranged offset in the cavities by half of their hollow profile cross-section.
- the building structure plate is provided with at least one centrally through their outer wide surfaces continuous, rectangular bore, which is cohesively and tightly connected to a bore diameter adapted pipe profile piece for the passage of a holding member.
- the structural panel can be cut both square and rectangular from the extruded profile, wherein the square embodiment has a central bore, while the rectangular embodiment have three holes, which are intended for the passage of Dübein or similar support members.
- the construction construction plate according to the invention If, in the construction construction plate according to the invention, the front edges which extend transversely to the extrusion direction and which correspond to the cut edges of the profile are firmly bonded to flat bodies, then the construction advantageously results in a multi-plate hollow space. If the material bond is effected under vacuum, then all the cavities would have been evacuated at the same time, which would additionally reduce the thermal conductivity of the building construction panel.
- the webs forming the cavities of the multi-web plate webs which are produced according to the invention by a plurality of distance-determining hollow profiles, advantageously experienced by the staggered arrangement in the adjacent cavities, a web extension, which extends the heat conduction paths.
- the resulting effect of reducing the heat transfer coefficient occurs at a plurality of different hollow profile cross sections, the best of which are described below.
- the distance-determining hollow profile is provided with a square cross-section and arranged edgewise between the wide surfaces of the building construction panel.
- the tubular formation of the distance-determining hollow profile with a circular cross-section.
- the distance-determining hollow profile is uniformly distributed over the circumference hexagonal, in this way results in a honey-shaped cross-sectional pattern with staggered arrangement in adjacent cavities of the building construction plate.
- this object is further achieved in that the plastic housing is assembled from two housing parts which are fixedly connected to each other, close off the inner cavity to the outside and at least have a poorly heat-conducting medium in the cavity.
- the large-area broad side surfaces of the housing walls in the interior are thermally insulated from each other by an intermediate, introduced in the cavity, poor thermal conductivity medium.
- the effective heat transfer path is structurally extended, so that the thermal conductivity of the building construction plate is significantly reduced while ensuring the required mechanical or static stability.
- both a low heat transfer coefficient and a high compressive strength is achieved.
- the large-area broadside surfaces are provided with at least one corresponding, aligned rectangular extending passage opening for the passage of a fastener and that the passage opening is sealed by means of a, both housing parts connecting wall opposite the inner cavity.
- both housing parts are made substantially the same and formed like a box with outer edge walls whose free edges form the housing part connection.
- the two housing parts may alternatively be designed unequal, such that one of which is formed like a box with outer edge surfaces and the other is formed by a cover-like housing plate.
- the gap between the connected housing parts in the region of the four narrow sides of the plastic housing is arranged and thus largely exempt from pressure loads.
- the two housing parts have a plurality of parallel extending, projecting into the inner cavity stiffening webs which are formed at right angles to the large-scale housing inner sides.
- the box-like of the two housing parts is made of an injection-moldable plastic, which may contain a fire-resistant aggregate.
- a commercial product from BASF with the name Ultramit A66 GF30 FR from the group of Spezialpoiyamide would be suitable.
- the proposed building construction panels meet the expectation to avoid a thermal bridge between the outer surface of the structure and the outer surface of the thermal insulation layer in solid structures, in particular building facades with externally superior thermal insulation layer.
- thermal bridges are formed by necessary high-strength support elements that must penetrate the thermal barrier coating for superior construction elements, such as balcony railing, window grilles, electrical system components and the like.
- the proposed building construction plates are intended as an intermediate layer between the outer surface of the solid construction body and the usual substantially L-shaped support element, which in turn can be designed in a simple and uncomplicated manner without further measures which prevent heat conduction.
- the particular advantage of the proposed building construction plate consists, on the one hand, in a serial or mass production which is economically possible by the extrusion process. On the other hand, in the case of a need for manufacturing a building construction panel with comparatively small numbers of pieces and a reduced outlay for storing the semifinished products, in some cases a further production method by means of a pressure or injection molding process could be considered.

- the two hollow spaces 15, 16 from each other separating inner plate wall 20 is in its wall thickness about twice as thick as the outer wall thickness of the wide surface 7. It can be seen that the distance-determining hollow section 17 used in Figures 3 and 4 is tubular with a circular cross-section.

- Figure 8 schematically illustrates the non-scale top view of a building construction plate 101 made of plastic, e.g. PVC, existing two housing parts 102, 103 are firmly connected to each other.
- the two housing parts 102, 103 are produced by injection or pressure casting and are preferably glued together, so that there is a tight connection.
- the plastic housing 104 thus formed includes an internal cavity 105 which is permanently separated from the surrounding outside air.
