Abstract

The claimed square or rectangular construction board (1, 2) meets thermal insulation requirements for buildings which are fitted with front panels with interposed damping material, such as rock wool or glass fibre mats, styrofoam or polyurethane plates. The front panels covering the thermal insulation layer are connected in a rigid and a storm-resistant manner to the building, generally, by means of metallic support and fastening elements, made from aluminium or stainless steel support profiles, penetrating the heat insulation layer. All known metallic support profiles form thermal bridges which reduce the insulating effect. Therefore, the claimed pressure-resistant, thermal insulation construction boards (1, 2) which essentially reduce the thermal bridge effect of the support and fastening elements without reducing the mechanical resistance of the thermal insulation layer, are taken into account. The claimed building construction board (1, 2) can be produced in a simple form from an extruded profile (3) or in an injection or die-casting method.

Description

Pressure-resistant, heat-insulating construction plate

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.

Although these webs can pass through the light passing through evenly because of their straightness, but are not particularly good thermal insulation nor sufficiently stable and absorbing force against high pressure loads, as they need to ensure building construction as thermal insulation between structures and superior components.

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.

According to the invention, 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.

Due to the embodiment of the invention with their non-rectilinear or ungleichlinigen training of the webs advantageous effective Wärmeieitweg is structurally extended, so that the thermal conductivity of the building board is significantly reduced while ensuring the required mechanical or static stability. In a further development of the embodiment according to the invention is provided with particular advantage that 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 advantage is that the building construction plate can be firmly anchored to both the building and with the thermal insulation, the retaining elements can be formed of commercial dowels.

As a result of the cohesive connection between the building construction plate and the pipe profile piece, the cavities of the web manifold plate are effectively sealed both with each other and outwardly.

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.

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.

With particular advantage, in a first embodiment of the construction panel, 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 particular advantage lies in the comparatively simple production of the extrusion die resulting from the extrusion die.

Similarly advantageous is the tubular formation of the distance-determining hollow profile with a circular cross-section. In a further advantageous embodiment, 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.

As an especially mechanically stable, an embodiment has been found in which the distance-determining hollow profile of two alternately different rectangular cross-sections is formed.

According to the invention, 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.

Due to the embodiment of the invention with its two housing parts, 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. As a result, advantageously, 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. As a result, both a low heat transfer coefficient and a high compressive strength is achieved.

In a further development of the inventive embodiment is provided with particular advantage that 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. Thus, the relative position of the building structure plate with respect to the outer surface of the structure and the support member to be mounted can be fixed by its fastening means. The seal makes it possible to maintain the properties of the poorly heat-conducting medium introduced in the cavity during production of the building construction panel, even under different weather and temperature conditions.

With particular advantage, three passage openings are arranged at a distance with each other centrally distributed on the large exterior sides of the housing. Thus, three fastening means can be used, which lead to a favorable distribution of forces under load of the support element. In a first embodiment of the invention, 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.

However, 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. In both embodiments, 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.

With regard to the pressure loads occurring, it is particularly advantageous if 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.

It is advantageous if the free, protruding into the inner cavity corresponding edges of the stiffening webs of both housing parts leave a continuous space for receiving a plate-shaped solid body of a poorly heat-conducting medium. This design allows the use of several poorly heat-conducting media, such as e.g. gaseous and solid substances.

In a further advantageous embodiment of the invention may be filled in development of the inventive idea in the cavity either only a gaseous or only a physical substance, such. an expanding poorly heat-conducting foam such as polyurethane.

This results in particular advantages if at least the box-like of the two housing parts is made of an injection-moldable plastic, which may contain a fire-resistant aggregate. For this purpose, for example, 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. Such 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. Further advantages and details of the building construction plates according to the invention will become apparent from the following description of the figures. Show it:

Figure 12 schematically shows a complete cross-section of Figure 8 of the building structure panel according to the invention in the region of section III-III.

With reference to the drawing with the figures, the invention will be described with several examples and explained their mode of action.

Figures 1 and 2 show schematically the plan views of a building construction plate 1 or 2 consisting of an elongated plastic material, e.g. made of PVC, existing rod-shaped extruded profile 3 is produced by separating cuts.

The building construction plate 1 is provided with three through-holes 4, which is formed by a pipe profile piece 5, which is connected to its outer wall 6 stoffsc liquid with the building board 1. The bore 4 extends centrally in the region of the broad surface 7 at right angles to this and forms with the circular passage cross-section 8 a guide for a not-shown cylindrical holding member, such as a fixing dowel or the like. As can be seen, the outer diameter of the bore 4 is adapted to the outer diameter of the tubular profile piece 5. The two long edges 9 of the building construction panel 1 run parallel to each other and exactly in the extrusion direction 10. The two parallel to each other and at right angles to the extrusion direction 10 extending narrow edges 11, 12 are made by cuts.

Visible is a sectional view in the region of one of the holes 4 along the line III-III shown in Figure 3, which in turn represents the cross-section of the building structure plate 1 with the bore 4. Another section IV-IV in Figure 4 shows the complete cross-section of the building structure panel 1 and thus of the extruded profile. 3

FIG. 2 shows, in a plan view very similar to FIG. 1, instead of a rectangular design of the building construction panel 1, a diagrammatic representation of a quadratic embodiment in which a section III-III is guided through the bore 4 and its tubular profile piece 5, which is shown in FIG 3 matches. Incidentally, the same parts are provided with the same reference numerals. The cut edges 11 and 12 are connected by plates 13, 14 cohesively with the building board 1.

Figures 3 and 4 show schematically the building construction plate 1 with a cross section of the extruded profile 3 in the form of a multi-plate plate, which is at least doubled, so that two parallel to the outer profile side surfaces 7 extending cavities 15, 16 form, which in turn of a plurality of distance determining Hollow sections 17 are filled, form the hollow profile walls 18, the stiffening webs 19.

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.

The difference of the representation between the figures 3 and 4 consists in the recess of the building construction plate 1 passing through hole 4. Incidentally, the same parts are provided in the figures 3 and 4 with the same reference numerals. FIG. 4 shows a detail in FIG. 4A on an enlarged scale in order to make the cross-section of the building construction panel 1, 2 on the one hand and the complementary cross-section of the associated extrusion die, not shown in detail, visible. FIG. 3 shows as a detail a dashed arrow 21 shown on the left side, which shows the characteristic course of the heat conduction path through the building construction panel 2. It goes without saying that between the upper wide surface 7 and the lower wide surface 7 parallel to it forms a plurality of heat conduction paths, which are invariably extended compared to straight stiffening webs, a Significant improvement in the heat coefficient condition and increase the pressure rating.

FIGS. 5 and 5A illustrate the cross-section of the building construction panel 1 in an embodiment in which the spacing-determining hollow profile in the web multiple panel is formed by two alternately different cross-sections. Incidentally, the same parts are provided with the same reference numerals. The same applies to the hollow sections shown schematically in FIGS. 6 and 6A or 7 and 7A and deviating from the previous ones. While square hollow sections are used in FIGS. 6, 6A, hexagonal hollow sections are used in the embodiment according to FIGS. 7, 7A, which with their profile walls form the stiffening webs of the building construction plate, namely with a considerable lengthening of the heat conduction paths. Incidentally, in this case the same parts are provided with the same reference numerals. With reference to the drawing with Figures 8 to 12, the invention will be described with a further preferred example and explained their mode of action.

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. The plastic housing 104 has on its two broad side surfaces 04a in the middle in a row three passage openings 108 for not shown fastening means, such as dowels and / or screws on which the

Position plastic housing 104 as an intermediate layer between a non-illustrated structure and a support member also not shown.

As can be seen from FIG. 8, the two broad side surfaces 104a are delimited by outer edge walls 109, 110, whose wall surfaces 1 1 1, 1 12 facing the cavity 105 mark the wall thickness of the two edge walls 109, 110 by means of the dashed lines. The parallel drawn to the elongated running edge walls 1 10 double dashed lines mark stiffening webs 1 13, 1 14, which are integrally formed on the two housing parts 102, 103, the inner cavity 105 on the one hand and on the other hand on each of the housing parts 102, 103 facing each other facing , The stiffening webs 1 13, 1 14 serve to accommodate the resulting pressure loads acting on the two broad side surfaces 104 a.

Each of the through holes 108 has, as the dashed circle around the circular contour shows, a continuous, the respective passage opening with respect to the cavity 105 sealing tubular wall 115 which connects the two housing parts 102, 103 with their broad side surfaces 106, 107 tight. In FIGS. 9 and 10, the two housing parts 102 and 103 are shown schematically in section in an exploded view in the direction of the dot-dashed center line 116, the same parts being provided with the same reference numerals. It can be seen that the parallel stiffening webs 113 left at its free edge 117 a web-free gap 1 18, which serves to receive a plate of a thermally insulating solid body 119. The solid body 119 may be embodied as a polystyrene or foam board of polyurethane or a layer of fiber materials.

Figures 11 and 12 show schematically the assembled housing parts 102 and 103, which have their connection joint 120 on the narrow sides 106, 107 of the plastic housing 104 approximately in the middle of the two edge walls 109, 110.

The connecting joint 120 is formed by corresponding overlapping wall parts 121, 122, which are connected to one another in a form-fitting or cohesive manner by adhesive and / or by heat treatment.
