Definitions
- the invention relates to a hollow plastic profile with a load-bearing wall for connection of two metal profiles with each other and with at least one foamable Hollow chamber.
- the invention further relates to a method Production of such a plastic hollow profile.
- the foaming of the hollow chamber (s) is in the profiles in question made a small-cell division of the volume of the hollow chamber (s) to achieve and so the thermal resistance of the hollow plastic profile or to increase its hollow chamber.
- the small cell division of the hollow chamber reduces heat transfer through the hollow chamber due to convection currents to a negligible value.
- thermal expansion occurs in those trapped in the foam Gas volumes on that for a further increase in the interior of the hollow chamber prevailing pressure.
- the insulating web including the supporting wall is deformed irregularly, which can lead to the material tearing and the hollow chamber bursting.
- tensions and expansion processes of the foam also occur, which, for example, result from the solar radiation of components made of composite profiles installed in facades, where temperatures of 80 ° C. and more can occur.
- the composite profile is still exposed to enormous temperature loads which, like the post-treatment processes, can lead to damage to the hollow plastic profile.
- the object of the present invention is to provide a hollow plastic profile to propose the type described, in which the problems described above are avoided.
- the hollow chamber has a volume with a cross-sectional area which is at least partially from one of the load-bearing Wall is limited to different hollow chamber wall and which one Expansion of the foam under the predetermined deformation of the hollow chamber wall with essentially dimensionally stable load-bearing wall.
- the cavity wall is designed so that it give way to the expansion of the foam under the conditions of the aftertreatment can, whereby it deforms in a defined manner. Because of this, the load-bearing wall are dimensionally stable, so that the deformation in the the strength of the composite profile plays uncritical area of the hollow wall. This makes it uncritical in non-critical areas of the plastic profile Obtain change in the cross-sectional area of the hollow chamber without it becoming a Tearing of the profile or bursting of the hollow chamber can occur. The same applies even when using the composite profiles in an environment that is subject to high temperature fluctuations can be expected.
- this also allows the cavity filled with foam as a construction element to take into account when designing the wall thickness of the profile, which can then be designed to be smaller, since the foam filling in the cavity stiffening the profile.
- the inventive design of the hollow profile also makes constructions easy to implement where the load-bearing wall together with the cavity wall limit the cross-sectional area of the cavity, d. H. the load-bearing wall directly that which builds up inside the hollow chamber Experiencing pressure.
- the deformable hollow chamber wall can be realized in many different ways respectively.
- the hollow chamber wall can have two separate longitudinal walls with free, End areas not connected to each other, which abut each other limit the cross-sectional area. Due to the material rigidity of the separate Longitudinal walls allow the hollow chamber volume to be filled Foam without it being able to escape. A deformation of the cavity wall and a concomitant increase in cross-sectional area is preferably avoided at this stage. This is the full capacity to increase the volume of the hollow chamber for the post-treatment steps and / or the time after the composite profiles have been installed at their destination to disposal.
- the hollow profile is a second hollow chamber which, from the first hollow chamber through a common wall, the part of the cavity wall is separated and that the common wall has a section which during the expansion of the foam from a first Position is movable into a second position, in the second position the common wall connects the first to the second hollow chamber is created and the volumes of the two hollow chambers together Flow connection.
- the hollow chamber opens in a defined manner and thereby expands the original volume of foam exiting into a predetermined Collection volume exceeds.
- Another conceivable solution in this embodiment would be the wall section on two longitudinal edges over a weakened area with the hollow profile to connect so that the wall section under which is exposed to temperature building pressure can be blasted off and thus the flow connection to creates a second cavity.
- Hollow chambers of hollow plastic profiles often have a polygonal cross-sectional area on.
- another alternative can be used it should be provided that at least two of the inner angles of the polygonal cross-sectional contour are different from each other and increase in volume align the hollow chamber with each other.
- the hollow chamber can initially be made in a state in which they are more the shape of an ellipse exhibits and deforms in the direction of a circular shape during expansion and thus the volume is increased in a defined manner.
- the hollow chamber bulges into the interior of the hollow chamber Longitudinal wall includes which is deformable when the foam expands. It can be provided that the first is inside the hollow chamber bulging longitudinal wall is deformed during the expansion of the foam so that the curvature faces outwards. This changes the geometry of the hollow plastic profile except for the change in the curvature of the longitudinal wall of the hollow chamber nothing, and the maximum can be determined using the depth of the specified curvature Specify the permissible increase in volume of the hollow chamber.
- the volume increases preferably in the range from 2 to 20% of the original cavity volume colonize.
- the permissible increase in volume is more preferably at least 5 to 10%.
- the invention further relates to a method for producing a hollow plastic profile, in which the plastic hollow profile is first produced with an empty hollow chamber the hollow chamber has a volume with a cross-sectional area, which is at least partially delimited by a cavity wall, whereby the cross-sectional area of the hollow chamber is reduced by a predetermined proportion is than at a permissible maximum volume specified for the hollow chamber, and a foam is fed into the hollow chamber and that the Cavity wall at an expansion of the foam essentially defines at dimensionally stable load-bearing wall is deformed so that the cross section of the Hollow chamber defined enlarged.
- the plastic hollow profile with the hollow chamber wall initially produced in one state for example extruded from a tool in which the cross-sectional area of the Hollow chamber from the outset by a predetermined proportion compared to the maximum permissible is reduced.
- the plastic hollow profile with the hollow chamber is manufactured (extruded) in a state by the hollow chamber has maximum volume or its final cross-sectional shape, and by in a subsequent step, a deformation of the hollow chamber wall is made so that it limits a cross-sectional area which by the specified proportion under the maximum cross-sectional area of the hollow chamber lies.
- This variant has the advantage that one and the same profile depending on the application of the later composite profile more or less strongly before filling can be deformed with foam.
- Figure 1 represents a hollow plastic profile 10 with a hollow chamber 12 and dimensionally stable supporting wall 14, to which the hollow chamber 12 is integrally formed is.
- the central arrangement of the hollow chamber 12 on the supporting wall 14 is not mandatory. Rather, the hollow chamber can, depending on the other Composite profile given special design features also arranged off-center and / or be divided into two or more parallel hollow chambers.
- the hollow chamber is supported by the dimensionally stable load-bearing wall 14 and by side surfaces 16, 17 and one extending between these side surfaces 16, 17 Wall 18 limited.
- the side surfaces 16, 17 and the wall 18 form thereby a deformable cavity wall.
- the side surfaces are 16, 17 in relation to the dimensionally stable load-bearing wall 14 Angle ( ⁇ ) arranged.
- the side surfaces 16, 17 are via foot points 22, 23, which have a slightly smaller wall thickness than the side surfaces 16, 17, connected to the load-bearing wall 14.
- the side surfaces 16, 17 are with the Wall 18 connected via corner areas 20, 21, which also have a lower material thickness have as the side walls 16, 17 and the wall 18th
- the height of the profile b1 increases when the parallelogram is set up Rectangular shape to the height b2, thereby increasing the volume of the Hollow chamber goes hand in hand.
- the height b2 or b1 and the width a of the hollow chamber are related to each other via the angle ⁇ , so that the given angle ⁇ (in the example 60 °) results in a volume increase of 16% when placed on the rectangular shape, which based on increasing the cross-sectional area.
- y A 2
- the load-bearing wall 14 ends at its longitudinal edges with bent areas 24, 25, which are designed such that their free end regions 26, 27 in a dovetail guide of a correspondingly designed metal profile (not shown here) can be introduced.
- the free ends 26, 27 each have a groove 28, 29 for receiving an adhesive, for example in the form of a plastic wire, and that during further processing the composite profile then to a shear-proof connection between Plastic profile 10 and the associated metal profiles.
- Figure 2 shows a variant of the hollow plastic profile designed according to the invention 10 in the form of a hollow plastic profile 30, which is built up from a load-bearing wall 32 and hollow chambers 34, 35.
- This embodiment serves on the one hand to visualize the possibility of using several parallel hollow chambers on a load-bearing wall, the load-bearing wall 32 here only to a small extent the limitation of the volume of the hollow chambers 34, 35 serves.
- this embodiment serves to explain the various Possibilities of designing the cross-sectional area of the hollow chambers 34, 35, being essentially circular in the maximally expanded state Cross-sectional area is obtained, while in the unexpanded state Cross-sectional areas are elliptical.
- the cross-sectional areas of the hollow chambers 34, 35 are then next to a portion of the load-bearing wall 32 of a hollow chamber wall 37, 38 limited, the wall thickness is designed so that the Deformation towards that of the maximum cross-sectional area in a circular shape results without an excessively large increase in pressure inside the hollow chambers 34, 35 would be necessary. This is supported by weaknesses in the wall 38 which are formed adjacent to the adjacent load-bearing wall 32.
- the load-bearing wall 32 ends at both of its longitudinal edges with cranked ends Areas 41, 42, which end with end areas 44, 45, which thus widened are formed that these are in dovetail guides with have the plastic profile 32 to be joined metal profiles.
- the end regions have 44, 45 grooves 46, 47 on the inclusion of adhesive (for example a plastic wire) for shear-proof connection of the plastic profile 32 with the metal profiles to be connected.
- FIG. 3 shows a section of profile 32 of FIG Figure 2 in the installed state between two metal profiles 48, 49.
- the metal profiles 48, 49 have dovetail-shaped grooves 50, 51, which receive the end regions 44, 45 of the profile 30.
- the inventive design of the profile 30 also comes under Thermal stress to no deformation of the load-bearing wall 32 of the profile 30, and only the cross-sectional area of the hollow chambers 34, 35 increases in the direction of a circular cross-sectional area and is therefore equal when exposed to temperature in post-treatment steps or when using the composite profile in environments with high temperature loads Expansion of the foam inside the hollow chambers 34, 35 from without this would otherwise lead to deformation of the hollow profile 30. That stays with it Hollow plastic profile 30 is a predictable load-bearing element in the composite profile construction and especially avoids the bursting or tearing of certain ones Splitting of the profile 30 under extreme temperature loads.
- FIG. 4 shows a further variant of a hollow plastic profile according to the invention, which is designated here overall by reference numeral 56.
- This Profile like those described above, has a load-bearing wall 58, which together with a deformable cavity wall 60 the volume of the cavity of the plastic profile 56 includes.
- the cavity wall is here 60 not in one piece, but consists of two separate longitudinal walls 62, 63, which each connect to the load-bearing wall 58 and from there extend from each other with their free, angled ends 64, 65 and overlap. This creates a closed cavity that holds the foam does not leak when filling. At a later temperature load can the foam expand, whereby the hollow chamber wall 60 dots into the dot-dash line shown position can move.
- the cranked end areas 70, 71 have free ends 72, 73, which widen in such a way that these from complementary dovetail guides in associated metal profile grooves can be inserted.
- Figure 5 shows a further variant of the plastic hollow profile according to the invention in the form of the profile 80, which is constructed from a load-bearing wall 82 which join two hollow chambers 83, 84.
- the larger of the two hollow chambers 84 (hereinafter also referred to as the first hollow chamber) is used for filling with foam and is enclosed by a hollow wall 85, which a Wall section 86 includes which is a partition to the adjacent extending Hollow chamber 83 forms.
- the wall section 86 of the hollow chamber wall 85 has one end over one Base 88 held on the supporting wall 82 while the other edge of the Wall section 86 is formed as a free end 89.
- This free end of the Wall section 86 initially abuts a projection 90 which extends along the length of the hollow chamber 84 extends into the interior thereof and over the entire length thus a stop for the free end 89 of the wall section 86 forms.
- foam If foam is now filled into the cavity 84, it fills the predetermined one Volume completely out, with the wall section 86 preferably in the solid line Representation shown position remains.
- the profile 80 is later exposed to thermal stresses that lead to expansion of the foam in the hollow chamber 84, the wall section 86 in the dash-dotted position or even further from the original Swivel position out and thus a flow connection between the hollow chamber 84 and the hollow chamber (second hollow chamber) 83. So that is a defined possibility for the expanding foam, from the chamber 84 to emerge, without this being visible on the outside of the profile.
- the profile 80 in turn has on its load-bearing wall 82 on its longitudinal edges cranked areas 92, 93 formed with widened end edges 94, 95 are inserted in complementary grooves of metal profiles are and thus result in a plastic-metal composite construction.
