Definitions

  • the invention relates to a spacer for discs of Mehrfachisolierglvessern, in particular for use in windows, doors od.
  • a spacer for discs of Mehrfachisolierglvessern Like., which consists of a hollow profile that is filled with a moisture-absorbing material.
  • Such spacers can be connected by bending and / or via a plug connection to a spacer frame, which is arranged between the panes of a Mehrfachisolierverglasung and then sealed by means of edge seal.
  • edge sealing one or two-stage systems are known.
  • hotmelt or butyl in a sealant width of at least 7 mm is preferably applied as an edge seal.
  • the primary sealant preferably butyl
  • the secondary sealant for example silicone, polyurethane or polysulfide.
  • This secondary sealant is applied in density widths of at least 4 mm, whereby a minimum coverage of the spacer back of 2 mm is desired.
  • the butyl ensures the water vapor and gas tightness.
  • the secondary sealant ensures the stability of the edge seal.
  • the object of the present invention is thus to achieve an equally good or better sealing a Mehrfachisolierglassystems with a smaller amount of sealant.
  • the solution of this seemingly contradictory task is achieved by a spacer with the features of claim 1.
  • the rear wall of the hollow profile projecting webs thereby limit a receiving space for the sealant, i. in single-stage systems, for example, for the hotmelt and in two-stage systems for the secondary sealant. No sealant is provided in the area between the two webs, i.
  • the rear wall of the hollow section is not covered with sealant.
  • the other part of the rear wall which is located outside the webs, formed as a deeper level.
  • hollow profile open or closed hollow profiles can be used, i. the outgoing from the rear wall of the hollow profile webs can also be provided in hollow sections without inner wall or with a larger opening in the region of the inner wall.
  • a sealant application on the outer surface of the rear wall of the hollow profile is also not necessary, since when using metal spacers, the metal material ensures better gas and moisture tightness than the aforementioned, known for the edge sealants.
  • the required by the quality community minimum sealant width of 7 mm for a one or two-stage system can be maintained even when using the spacer according to the invention.
  • a space for the primary sealant may, in one embodiment of the spacer according to the invention, in which the walls give a nearly box-shaped cross-section, through the respective, the glass pane be limited opposite side wall. Also in this embodiment, the required minimum sealant width can be achieved.
  • the side walls are approximately parallel to the discs and approach the disc in the direction of the inner wall in their lower corners. These corners represent a boundary of the primary sealant gap to the disk interior. This primary sealant space is greatly tapered at this point, so that penetration of primary sealant into the space between the panes is made more difficult.
  • the distance between the lower corners of the side wall and the inner wall corresponds to the spacer width.
  • the friction during transport and in the guidance of the spacer profiles in bending devices or other processing machines is reduced by this profile shape, since the profile no longer has to be detected on the entire side wall to move, but only at the outermost points, the corners, which are formed by the inner wall and the side wall, namely the so-called boundary points.
  • the primary sealant width may further be formed or increased by legs which extend the side walls of the hollow profile and protrude beyond the inner wall facing the disc interior and provided with perforations.
  • a receiving space for the secondary sealant is bounded on the one hand by the disc and on the other hand by a projecting from the rear wall web laterally. Down the delimitation of the receiving space takes place in providing a deeper level of the rear wall through this located outside the webs level of the rear wall.
  • the size of the receiving space for the secondary sealant changes due to the length and positioning of the webs according to the invention. These bars should be at least 1.5 mm long. For bendable spacers preferably webs with a length of 1.5 to 3 mm are conceivable.
  • the rear wall outside the webs is formed as a step, so that increases the receiving space for the secondary sealant.
  • the length of the bars can be extended to a maximum of 5 mm.
  • the minimum length of 1.5 mm results from the fact that a sufficient surface for the adhesion of the secondary sealant must be made available.
  • the webs may project at right angles from the rear wall, but may also be inclined, the inclination of the webs preferably being provided so as to extend away from the disks, i.e. from the rear wall of the spacer. are inclined towards each other.
  • This inclination of the webs allows a good flexibility of the spacer to a spacer frame, preferably also at the corners. There is no tearing of the spacer profile at the corners, since the webs create in this area on the rear wall.
  • the better bendability of the spacer according to the invention is further evident from the fact that in the inventive spacer profile over spacers of the same height the rear wall moves closer to the neutral chamfer and thus the elongation of the rear wall is reduced during bending.
  • the spacer according to the invention can be filled and unfolded bend, wherein at the same height of the interior of the spacer profiles for the desiccant is smaller, i. In addition, desiccant can be saved.
  • the walls of the spacer are concave, ie curved in the direction of the interior. This leads to a better tightness of the insulating glass, since the spacers the possible, caused by wind and climatic influences movements of the Can compensate for glass. Furthermore, this spacer shape supports the better bendability of the profile, since the rear wall and inner wall are aligned towards the neutral chamfer and are thus less stressed during bending. Concave sidewalls also increase the primary sealant space, so that in this case a larger butyl reservoir can be provided.
  • An inventive spacer for Mehrfachisolierverglasungen consists of a hollow profile 1, which contains a moisture-absorbing material in its interior 4, which is not shown in the figures.
  • This interior 4 is bounded by two side walls 10, the rear wall 5 and the inner wall 6.
  • the inner wall 6 has a wall weakening. In this area of the wall weakening perforations 14 are arranged, which allows a connection of the disc interior 21 with the interior 4 of the hollow profile 1 for the purpose of moisture absorption.
  • the hollow profile 1 according to the invention with two rear wall 5 of the hollow section 1 superior webs 3 is provided. These webs 3 are inclined away from the disks 20, and have a length L1. In principle, the webs 3 can be arranged at any desired location of the rear wall 5. In an advantageous manner, however, these are provided in the hollow profile 1 in the region of the rear wall 5, where the rear wall 5 merges into the step 28.
  • the step 28 forms with the side wall 10 a corner 27th
  • a box-shaped hollow profile 1 is shown.
  • the interior 4 is limited in this spacer hollow profile 1 by an approximately parallel rear wall 5 and inner wall 6 and by approximately parallel side walls 10.
  • the webs 3 are spaced from the glass sheets 20 to obtain a sufficiently large receiving space 24 for the secondary sealant.
  • the outgoing from the rear wall 5 webs 3 are arranged obliquely and inclined towards each other. This is particularly advantageous when bending spacer frame corners. Vertical bars would have to be deformed during bending over the high edge, which is problematic and leads to tearing of the webs or even the profile in this corner area. As a result of the inclination of the webs 3, they bend against the outer side 17 of the rear wall 5 during corner bending without damaging the hollow profile 1.
  • the gap 23 for the primary sealant is laterally limited by the side wall 10 and the disc 20, preferably, the gap 23 tapers downwards.
  • the side wall 10 has a lower corner 25 with the inner wall 6. This corner 25 is formed so that it represents a lower boundary point 26 for the gap 23. There is no direct contact of the corner 25 with the glass pane 20, nevertheless, the primary sealant is held substantially in the intermediate space 23.
  • the upper corner 27 of the respective side wall 10 is in the example Fig. 3 spaced from the disc 20 so that the gap 23 for the primary sealant and the receiving space 24 for the secondary sealant merge into one another. This can be particularly advantageous in insulating glass systems that are exposed to large lateral forces.
  • the corner 27 set back relative to the lower corner 25 the glass pane 20 has the possibility of pivoting at a greater angle under pressure loads, without the sealant being torn off the pane 20 and leading to a leak in the system.
  • a minimum sealant width of 7 mm is required for one or two-stage systems.
  • the spaces 23 shown in the examples for the primary sealant and receiving spaces 24 for the Secondary sealants can also be used for a single-stage packing system.
  • the required width B1 of the primary sealant surface results as the longest extent of the gap 23.
  • the sealant widths B1 and B2 are shown.
  • the width B1 is at least 3 mm.
  • the width B2 of the secondary sealant surface extends to the end face 18 of the web 3 or the end face 22 of the glass pane 20. However, the end face 18 of the webs 3 does not have to end at the same height as the end face 22 of the glass panes 20.
  • the secondary sealant is provided in two receiving spaces 24 each between a web 3 and the adjacent disk 20. Down the receiving space 24 is limited by the transition to the gap 23. In the example of Fig. 1 the receiving space 24 is limited downwards substantially through the outer regions of the rear wall 5.
  • the rear wall 5 is formed as a step 28, which is arranged lower than the rear wall 5.
  • the outer surface 17 of the rear wall 5 is not continuously coated with sealant, ie it saves secondary sealant.
  • An impairment, in particular the tightness of Mehrfachisolierglassystems is not recorded.
  • the back panel at the corners may be coated with secondary plastic sealant to ensure tightness. In any case, this means a significant saving on the expensive secondary sealant, for example on polysulfide.
  • the amount of secondary sealant depends on the size of the receiving space 24. This can be influenced on the one hand by the distance A of the web 3 of the disc 20 and the other by the length L1 of the web 3.
  • the length L1 of the web 3 should ensure a good adhesion of the secondary sealant, at least 1.5 mm.
  • the webs 3 are limited to a maximum of 3 mm and for other spacers to a maximum of 5 mm.
  • the hollow profile 1 according to the invention is advantageously characterized by a comparatively small interior space 4. Compared with known spacer profiles, the hollow profile 1 according to the invention has a smaller maximum height Hmax. This results from the comparison with known spacers staggered arrangement of the rear wall 5 in the direction of the interior of the fourth
  • the aforementioned indentation 16 of the inner wall 6 further leads to an additional reduction of the interior 4 for the moisture-absorbing material.
  • the maximum height Hmax of the inner space 4 in the region of the perforation 14 decreases to a minimum height Hmin of the inner space 4.
  • the smaller inner space 4 can be used to save moisture-absorbing material for a spacer.
  • An indentation 29 can also be provided on the rear wall.
  • the subject of the invention is not on the embodiment of the Fig. 1 to Fig. 2 limited.
  • the invention also relates to spacers from an open hollow profile, where an inner wall 6 is completely or partially omitted. Also in these cases, outgoing from the rear wall 5 webs 3 can be provided in an advantageous manner. There are also other embodiments conceivable.
