Definitions
- the invention relates to hollow hollow profile bars made of plastic for installation in composite window panes.
- Such hollow profile rods made of a plastic are known from DE 196 44 544 Cl.
- a mixture of hard and soft polyacrylic was used as the plastic, which provided advantageous processing properties and very low heat transfer compared to light metal rungs.
- a disadvantage of using such hollow profile strips in laminated glass panes is that the coefficient of expansion of the plastic is very much greater than that of the spacer strips with which the glass panes are connected on the edge side. This causes e.g. as a result of solar radiation, compression and warping of the profile strips on and at low temperatures their loosening in the seat on end connectors on the spacer strips.
- the rungs consist of at least two layers, of which an inner layer consists of a glass ball or glass fiber doped ABS (acrylonitrile butadiene styrene polymer) and an outer, thinner layer consists of a PMMA (polyacrylate).
- ABS acrylonitrile butadiene styrene polymer
- PMMA polyacrylate
- the specific thermal linear expansion of the spacer strips, which are made of aluminum, is 2.35 x 10 5 1 / K, and the specific thermal linear expansion of glass-filled ABS comes very close to this with 3 to 4 x 10 5 1 / K, whereas the polyacrylics has about three times higher thermal linear expansion.
- the novel rungs, which essentially consist of the glass-filled ABS, provide a significantly better expansion behavior than the known ones in practical use.
- the cover layer which is about 0.2-0.6 mm thick and preferably has about 1/3 to 1/5 of the total wall thickness, serves the UV light resistance and the thermal resistance of the overall structure.
- the coextruded top layer has a high level of smoothness and a high degree of gloss, which cannot be achieved with glass-filled material.
- the profile can have an approximately constant wall thickness or can also have inner webs or ribs or, at suitable points, thickenings, as is known from light metal rungs.
- the inner structure is preferably created entirely in the glass-filled plastic material; only the co-extruded outer skin is made of the smooth, shiny and UV-resistant material.
- the service temperature range of both materials together reaches up to approx. 110 ° C, although the cover layer material can only be used up to 100 ° C in terms of strength it is sufficient that the glass-filled carrier material is still loadable up to 110 ° C. This is particularly important in the case of strong solar radiation for the cross rungs, since these are located in the thermally insulated space between the glass panes, the i. a. is filled with a poorly heat-conducting inert gas, heat up very close to the full temperature range, especially if they are colored dark.
- FIG. 1 shows a cross section of a quadrant of a rung according to the invention adjacent to a glass pane G of a laminated glass pane.
- the cross section shown is a known outer contour of a rung, which has a rectangular basic shape with concave indented corner areas.
- the outer dimensions of the basic shape are, for example, 26 mm x 8 mm, and the retracted corner areas are approximately 7 mm long and 2.4 mm wide, the transitions being rounded.
- the total wall thickness D is predominantly approximately 1 mm and the proportionate thickness DE of the external protective layer is approximately 0.3 mm.
- the thickness of the outer layer 2, which consists of PMMA, can be between 0.2 and 0.6 mm in order to carry out the protective function without the thermal expansion of the superimposed plastic being too great.
- the inner carrier layer 1 made of glass-doped ABS should be at least as thick as the outer layer (2) and at least 0.5 mm thick. Both layers 1, 2 complement each other with regard to the load-bearing capacity, ie the section modulus, in a known manner according to the overall wall thickness.
- the load-bearing capacity of the horizontal rungs is largely determined by the narrow area S lying at the top and bottom.
- the wall thickness ⁇ TDS of the support layer 1 in the example about 1 mm, approximately twice as thick as the rest of the support wall thickness TD, which results in a relatively greatly increased load-bearing capacity with little material expenditure.
