Definitions

  • the invention relates to a profile frame construction with the features of the preamble of claim 1.
  • Profile frame constructions are used in facades, windows and doors and include a basic profile and insulating glass consisting of glass elements with a glass pane facing the basic profile and a glass pane facing away from the basic profile.
  • a basic profile and insulating glass consisting of glass elements with a glass pane facing the basic profile and a glass pane facing away from the basic profile.
  • vacuum insulating glass the space between the glass pane facing the basic profile and the glass pane facing away from the basic profile is evacuated.
  • airtight and vapor-tight edge strips are provided between the two glass panes, which limit the space to be evacuated.
  • Vakuumisoliergläser have the advantage of high thermal insulation, because the heat transfer in the evacuated space between the panes can largely be carried out by thermal radiation '.
  • vacuum insulating glass that has an inorganic edge bond such as glass solder, enamel, etc.
  • no desiccant must be provided in the edge bond.
  • a vapor pressure equalization in the glass rebate between two neighboring vacuum insulating glasses can be omitted.
  • the invention has for its object to provide a profile frame construction that is simple in construction and has a good visual appearance.
  • the invention is based on the idea of designing a profile frame construction with a basic profile and glass elements designed as vacuum glass in such a way that only the glass pane facing the basic profile is fastened against the basic profile by means of a holding device.
  • Vacuum glass consists of a glass pane directed towards the basic profile and a glass pane directed away from the basic profile, the space defined between the glass pane directed towards the basic profile and the glass pane directed away from the basic profile and between the airtight edge strips arranged between them being evacuated.
  • the glass pane facing the basic profile corresponds to the room-side glass pane, while the glass pane facing away from the basic profile corresponds to the outside glass pane.
  • a profile frame construction so that the supporting structure in the form of the basic profile is directed towards the outside of the room.
  • the term “vacuum glass” is intended to make it clear that the solution according to the invention works with all double glasses in which the atmospheric pressure always exerts an excess pressure on the glass pane directed away from the basic profile. For example, assuming a maximum wind suction load of 5 kPa, a difference between the outside pressure and the inside pressure between the two glasses of about 7 kPa is sufficient to ensure the holding function.
  • the "vacuum" between the glass elements can also be a relatively low vacuum.
  • a maximum wind suction load of around 10 kPa can also occur in particularly exposed areas, which results in a higher difference between external pressure and internal pressure.
  • an increase in temperature in the glass gap increases the pressure in the glass gap.
  • Another possible additional effect can be through the use of glazing at higher altitudes, for example in mountain stations. In this case, the reduced outside air pressure compared to normal conditions must also be taken into account.
  • the term “outer seal” is intended to denote that seal be in contact with the glass pane facing away from the basic profile.
  • At least one main dimension in the main surface of the glass pane facing the basic profile is larger than the corresponding at least one main dimension of the glass pane facing away from the basic profile.
  • the distance between the glass panes directed towards the base profile is smaller than the distance between the glass panes directed away from the base profile.
  • the outer seal lies in the glass rebate on the glass pane facing the basic profile on the side which faces the glass pane facing away from the basic profile.
  • the holding device in turn rests on the outer seal. This measure shifts the outer seal towards the base profile.
  • the interposed outer seal ensures that the glass pane facing the base profile cannot be damaged by direct contact with the holding device.
  • stepped insulating glass in particular in connection with the arrangement of the outer seal described above, makes it possible to design and attach the holding device such that it essentially flush with the outer surface of the glass pane facing away from the basic profile. This measure improves the overall visual appearance of the profile frame construction, particularly in facade construction.
  • the edge composite strips are spaced apart from the end faces of the glass pane facing the base profile of the glass pane directed towards the base profile as well as away from the base profile and the holding device engages positively from the glass fold area into the space between the glass pane directed towards the base profile and the glass pane directed away from the base profile on. In this way it is possible, even without the use of stepped insulating glass, to fix the glass pane facing the basic profile to the basic profile with the aid of a positive locking device.
  • the holding device is shaped such that the head of the facade screw can be countersunk.
  • an essentially smooth surface can be produced on the side of the entire profile frame construction facing away from the basic profile.
  • the holding device is a clamp with two legs, which engages around the glass pane facing the basic profile with the first leg and engages with the second leg in a corresponding groove in the basic profile.
  • the use of a U-shaped bracket is a very simple and inexpensive variant of the holding arrangement.
  • Fig. 1 is a schematic partial view of a
  • FIG. 2 shows the vacuum glass used in the profile frame construction according to FIG. 1;
  • Fig. 3 shows an alternative embodiment of a profile frame construction according to the invention using the vacuum glass shown in Fig. 2;
  • Fig. 4 shows an alternative embodiment of a profile frame construction according to the invention in schematic representation using a step vacuum glass

  • the embodiment of the invention shown in Fig. 1 shows a base profile 12, which has the function of an inner support profile.
  • the basic profile 12 can be designed in any manner except for the embodiments explained below in accordance with FIGS. 3 and 4 and can be made of any materials, such as, for example, Stainless steel, extruded aluminum, rolled steel, copper, plastic or even wood. If the profile frame construction according to the invention is used in the area of windows or doors, those skilled in the art are also familiar with those geometric adaptations which have to be carried out on the basic profile compared to the examples from facade construction explained in the following figures.
  • sealing strips 14 are applied in an unspecified manner, which can be fixed, for example in a manner not shown, in fastening receptacles in the base profile 12.
  • the two vacuum glass elements 16 are in contact, each consisting of a pane 18 directed towards the basic profile and a pane 20 facing away from the basic profile, as well as edge composite strips 22 arranged between the panes, which consist of an inorganic material, such as glass solder or enamel, and at the same time act as a spacer between the disk 18 facing the base profile and the disk 20 facing away from the base profile.
  • the edge composite strips 22 define a gas-tight (airtight and vapor-tight) closed and completely enclosed pane interspace 24, which is evacuated to a sufficiently low pressure that the two panes are held together by a maximum air pressure of approximately 0.1 MPa.
  • a firm bond is created between the pane 18 facing the basic profile and the pane 20 facing away from the basic profile, so that there is no need to mechanically hold the pane 20 facing away from the basic profile in addition to the pane 18 facing the basic profile, as is the case with glued glazing is common.
  • the space between the glass elements does not have to be evacuated as much as is usual with vacuum insulating glasses.
  • the disk 18 directed towards the basic profile is fixed against the basic profile 12 by a holding device 26, in that a facade screw 28 is screwed to the basic profile 12.
  • a facade screw 28 is screwed to the basic profile 12. This can either be done by screwing the facade screw 28 directly into the basic profile 12, as shown in FIG. 1, or a screw channel is formed on the basic profile 12, in which the facade screw 28 engages with the thread.
  • the latter solution is generally preferred in facade construction because no moisture can penetrate into the interior of the basic profile 12.
  • the holding device 26 is designed to engage in the space between the disk 18 facing the basic profile and the disk 20 facing away from the basic profile and is further provided with a suitable countersink in order to accommodate the head of the facade screw 28 in the material of the holding device 26.
  • the edge composite strip 22 In order for the holding device 26 to be able to engage in the space between the pane 18 facing the basic profile and the pane 20 facing away from the basic profile and thus to make a form-fitting contact with the pane 18 facing the basic profile, the edge composite strip 22 must not directly in the region of the end closure of the vacuum insulating glass element 16 be arranged. This is also clear from the illustration in FIG.
  • the edge composite strip 22 is set back by a distance d from the end faces 30 of the pane 18 facing the base profile and the disc 20 facing away from the base profile, the size of which depends on the shape of the shape Holding device 26, the size of the forces to be transmitted and thus also the size and weight of the vacuum glass element depends.
  • the distance d is in the range between 4 and 20 mm and preferably between 6 and 10 mm.
  • the outer seal 32 is a sealant seal.
  • the vacuum glass elements 16 can also be fixed against the base profile 12 in the manner shown schematically in FIG. 3.
  • the base profile is provided with a receiving groove 34 or undercut, which enables the disk 18 directed to the base profile to be fixed on the base profile 12 with the aid of the fastening device 36.
  • the fastening device 36 consists of a U-shaped, groove-shaped element which can be inserted in the direction perpendicular to the plane of the drawing in FIG. 3 for fastening the vacuum glass pane 16 to the base profile 12.
  • the trough-shaped element 36 has two legs which are connected to one another by a base.
  • the first leg engages in the space between the disk 18 directed towards the basic profile and the disk 20 directed away from the basic profile, while the second leg engages in the receiving groove 34 on the opposite longitudinal side of the base part. Due to the length of the legs and the distance between mutually facing end faces of the vacuum glass elements, the fastening element 36 cannot fall out or slip out by a movement in the plane of the drawing in FIG. 3, but only by a movement perpendicular to the plane of the drawing in FIG. 3 over the length of the fastening element 36 can be removed.
  • the fastening variant shown in FIG. 3 is very simple and, in particular, also easy and inexpensive to carry out with regard to assembly.
  • FIGS. 4 and 6 show further embodiments of a profile frame construction according to the invention which use a vacuum glass element 40 in which the pane 42 directed towards the basic profile has a greater extent than the pane 44 directed away from the basic profile.
  • This is shown schematically in FIG. 5 and is referred to as step glass.
  • a pane interspace 24 is likewise formed between the pane directed towards the base profile and the pane directed away from the base profile, said space being limited and evacuated by the airtight edge composite strips 22, which also serve as spacers.
  • the design of the vacuum glass element 40 can, according to the embodiment according to FIG. 4, which essentially corresponds to the embodiment according to FIG.
  • a fastening element 36 in the form of a U-shaped, channel-shaped element, which has the second leg in the receiving groove or undercut 34 in base profile 12 and with the first leg rests on the main surface of disk 42 facing disk 44.
  • This can be done either by direct contact or, as shown in the exemplary embodiment according to FIG. 4, by interposing an outer seal 32, which is arranged above the two end faces 30 of the disk 42 directed towards the base profile and the disk directed away from the base profile 44 rests and extends over the intermediate step area of the step glass pane 40.
  • the holding element 36 in the embodiment according to FIG. 4 is designed in coordination with the thickness of the outer seal 32 and the geometry of the vacuum glass 40 such that the fastening element 36 is flush with the main surface of the pane 44 in the assembled state.
  • a holding device 36 is again used instead of the retaining clip as a fastening element, essentially corresponding to the embodiment according to FIG.
  • a further difference lies in the fact that the outer seal 32 is shaped and designed slightly differently and, in accordance with the embodiment shown in FIG. 4, bears directly on the edge composite strip 22, but no longer on the end face of the disk 42 directed towards the basic profile.
  • the holding device 26 is braced against the base profile 12 using a facade screw 28, wherein in contrast to the embodiment according to FIG.
  • the pressure from the holding element 26 does not act directly on the disk directed towards the basic profile, but is transmitted to the disk 42 directed towards the basic profile with the interposition of the outer seal 32.
  • the holding element 26 is in turn shaped to receive the head of the fastening screw 28 in a suitable countersink, so that a facade surface that is essentially flush towards the outside is created.
  • the illustrated embodiments have in common that the vacuum glass is fastened to the basic profile by the pane facing the basic profile being fastened directly to the basic profile via a mechanical positive connection and the pane directed away from the basic profile being pressed by the air pressure in the direction of the pane facing the basic profile and is therefore also held to the basic profile.
  • the fastening alternatives shown in FIGS. 1, 3, 4 and 6 in the form of the holding device 26 or the fastening element 36 can each be designed as continuous strips or can only be provided in a punctiform manner.
  • All of the illustrated embodiments have in common that, depending on the degree of negative pressure, a highly thermally insulated, extremely transparent all-glass facade can be produced, which also has a high level of security due to the mechanical holder.
  • the mechanical brackets are barely visible because there is no need for additional mechanical securing of the panes directed away from the basic profile.
  • cost savings can be achieved by not using structural sealant glazing (SSG).
