Description

The present invention relates to a mullion and transom construction, in particular for facades, light roofs or sloping roofs, according to the preamble of claim 1.

The DE 203 18 083 U1 discloses a post-and-beam construction in which a screw channel is formed on each of the support profiles. An insulating strip is inserted into the screw channel and extends between the end faces of two filling elements. Although the insulation strip can improve the thermal insulation, the protruding screw groove only allows a compact design to be obtained to a limited extent. In addition, the screw groove of the support profile cannot be used for other purposes, since it is required to fix the insulating strip and the screws for a pressure strip.

The DE 296 11 109 U1 discloses a steel-glass facade in which the laminated glass panes are fixed by means of slot nuts and bolts. A glass holder is provided around bolts in two corner areas, the area between the glass holders not being insulated, so that only a low level of thermal insulation can be achieved.

In the DE 10 2012 104 000 B4 a post-and-bar arrangement is disclosed in which a plurality of holders are inserted into a groove of a profile part. The holders are used to pre-fix a strip-shaped insulation body that is attached to the holder. To fix the plate elements on the profile part, additional fastening means are required, which are fixed to the groove of the profile part and are introduced from the outside through the insulation body. As a result, the post-and-rail arrangement requires a comparatively large number of components, which makes assembly complex.

The DE 37 42 723 C1 discloses a frame construction in post-and-beam construction in which an insulating profile is inserted into a screw groove. The insulating profile is fixed by several metallic safety bolts.

In the DE 296 11 109 U1 a steel-glass facade is disclosed in which a glass holder is penetrated by a bolt which is fixed to a bolt via a sliding block

The EP 2 787 139 A1 discloses a mullion and transom construction according to the preamble of claim 1.

It is therefore the object of the present invention to create a mullion and transom construction which enables a simple assembly of a strip-shaped insulating element in the space between two filling elements and a flexible design of the support profile.

This object is achieved with a mullion and transom construction with the features of claim 1.

According to the invention, the strip-shaped insulating element is slipped or pushed through at least one bolt. As a result, the insulating element is no longer fixed to a screw groove, so that this area on the support profile can be used for other functions. The installation of the insulating element can be done simply by plugging it onto one or more bolts, so that a pre-fixing is achieved. After a holding or pressure strip has been installed on the outside of the filling elements, the insulating element is in any case arranged in a protected manner and is only exposed to low forces.

According to the invention, the at least one bolt extends through the insulating element. The insulating element can be designed to be closed before assembly, so that an opening is only produced by pushing the insulating element onto the bolt, which enables flexible adaptation to different distances from the bolts. Alternatively, it is possible to provide prefabricated openings or recesses on the insulating element, through which the bolt is then passed. The insulating element is plugged onto several bolts so that the insulating element is securely held on the bolt before the final assembly with the pressure strip takes place. The bolt can be designed as a pin, a threaded bolt, a prismatic body with and without an undercut or as a screw.

In a further embodiment of the invention, a groove is formed on the support profile, into which a head connected to the bolt is slidably inserted in order to fix a retaining strip in a clamping manner on an outside of the filling elements. The bolts can protrude between the filling elements so that the insulating element can easily be slipped onto the bolts during assembly. The bolts penetrate the insulating element, but can penetrate it.

For good thermal insulation, the insulating element extends from an outside of the filling elements to an inside. The insulating element can have at least two webs that extend completely from the outside to the inside of the filling elements, whereby a shorter design of the insulation elements is also possible, which does not extend completely from the outside to the inside. At least one projection in the direction of the end face of the filling element can be provided on a web, so that the gap between the insulating element and an end face of the filling element is divided into one or more chambers, even if the projection does not touch the end face. Because even the reduction in air circulation and air flow in the gap between the insulating element and the end face of the filling element can have a positive effect on thermal insulation.

According to the invention, the insulating element has two parallel webs which extend in the direction from an outside to an inside of the filling elements. The bolt is passed between the two webs so that the webs have a guide function during assembly. The webs consist of a harder material than a filling material between the webs, so that when the insulating element is put on, the softer filling material can easily be displaced by the bolt, but the harder webs take on a guiding function.

One or more filled chambers can also be provided on the insulating element. Materials for different functions can be arranged in the chambers, on the one hand for thermal insulation and on the other hand also as a drainage channel or also for fire protection. For fire protection, a chamber can be filled with a material that foams under heat.

Preferably, the bolt or the pin or the screw can also be attached to the pressure strip and the pressure strip including strip-shaped insulating element can be mounted. As a result, assembly takes place from the outside, the strip-shaped insulating element and the pressure strip forming a preassembled unit with the fastening means, which is then fixed to the support profile with the filling elements. One or more slot nuts are then mounted on the central groove of the support profile, in which the fastening means or bolts are then mounted on the pressure bar.

According to the invention, an insulating element for a post-and-beam construction is also provided. Existing post-and-beam constructions can also be retrofitted with the insulating element.

A post-and-bar construction 1 comprises a support profile 2, which can be designed as a post or bar and on one side a first groove 3 and a has a second groove 4 for receiving a sealing strip 6 in each case. A central groove 5 is formed between the grooves 3 and 4, into which a head 9 of a bolt 8 is inserted. A plurality of bolts 8 can be arranged at certain intervals over the length of the groove 5.

The support profile 2 is used to fix two filling elements 7, which can in particular be designed as insulating glass panes. The insulating glass panes lie on the edge side in each case on a sealing strip 6 on the side facing the support profile 2 and are fixed in a clamping manner on the opposite side by a sealing strip 13. Two sealing strips 13 are held on the outside on a holding strip 10 and the holding strip 10 is pretensioned towards the support profile 2. For this purpose, threads are provided on the outside of the bolts 8, onto each of which a nut 11 is screwed. As a result, a clamping fixation of the holding bar 10 can be obtained over the length of the holding bar 10, the bolts 8 being secured on the undercut groove 5 against being pulled out with respect to the head 9.

Insulating glass panes can be used as filling elements, with in Figure 1B two glass panes 70 are spaced apart at the edge via a spacer 71. It is also possible to use insulating glass panes with more than two glass panes 70.

A strip-shaped insulating element 20 is provided between the end faces of the filling elements 7, which is shown in FIG Figure 1A shown in detail. The insulating element 20 consists of an insulating material, in particular of plastic, an elastomer, a foamed plastic or other materials, and comprises a web 21 which extends essentially parallel to the end faces of the filling elements 7. On the outside of the web 21, two protruding arms 22 are formed, which rest with an underside on an outside of the filling elements 7. A surface 23 facing the filling elements 7 can be coated with adhesive, but can also be free of adhesive. The adhesive can be provided with reflective means, such as, for example, a reflective film. On the opposite inner side of the insulating element, a projection 24 with a V-shaped cross-section is formed, which extends up to close to the end face of the two filling elements 7. The V-shaped projection 24 divides a gap between the web 21 and an end face of a filling element 7 into two chambers, which improves the thermal insulation. It is also possible to provide several projections 24 on the web 21 which extend in the direction of the end face of the filling elements 7.

The strip-shaped insulating element 20 is pushed onto the bolt 8, with corresponding Figure 1C openings 25 for passing a bolt 8 through are provided centrally on the arms 22. The openings 25 can be provided at regular intervals. There is no web in the area of the openings 25 21, but only one recess 26, so that the bolt 8 can be positioned in the recess 26 between the webs 21.

Alternatively, the material of the insulating element 7 can be selected in such a way that an opening for passing the bolt 8 through in the arms 22 and the web 21 is created when it is slipped on.

In the assembled position, the insulating element 7 is additionally fixed by the arms 22, which are clamped between the sealing strips 13 and the outside of the filling elements 7.

In Figure 1D the post-and-beam construction 1 is shown during assembly. The filling elements 7 rest against the sealing strips 6 on the support profile 2. Bolts 8 with a threaded section protrude between the two filling elements 7, onto which the retaining strip 10 with elongated holes 12 is pushed.

This in Figure 1D The insulating element 20 'shown is slightly modified compared to the insulating element 20 and additionally has further projections 24 on the web 21, which subdivide the space between the web 21 and an end face of the filling element 7 into individual chambers. The insulating element 20 'is divided into individual sections for the assembly, which are each assembled between two bolts 8 and are pushed onto the bolts 8, in which each section is clamped between the bolts 8.

In the following exemplary embodiments, the mullion and transom construction 1 is essentially identical to the support profile 2 and only a different insulating element is used. Therefore, the same components have been given the same reference numerals and only the insulating element is primarily explained below.

In the Figures 2A to 2C a modified insulating element 30 is installed on a post-and-beam construction 1, which comprises a web 31 which extends parallel to the end faces of the filling elements 7. On the outside, the strip-shaped insulating element 30 is not T-shaped as in FIG Figure 1A , but only provided with two arms 32 which project substantially perpendicularly from the web 21 and between which a groove 35 is formed. At the bottom of the groove 35, two webs 36 which are arranged tapering in a V are formed. The arms 32 can rest with an underside 33 on the outside of the filling elements 7. The groove 35 is used with the preferably V-shaped contour Screw guidance in the areas where no bolts come into contact. To pass through a bolt 8, the web 31 is provided with a recess 37 which extends to the bottom of the groove 35, at which an opening 38 is provided.

On the opposite inner side, the insulating element 30 has two V-shaped projections 34 which are formed from a different material than the web 31, in particular a softer material that is bendable. As a result, the projections 34 can be bent over if there are tolerances with regard to the spacing of the filling elements 7. In addition, several projections 34 can also be formed on the web 31.

For assembly, the insulating element 30 is pushed back onto the bolts 8, the groove 35 being able to serve as an assembly aid in order to pass through an end section of the bolt 8 between the two arms 32 at the opening 38.

In Figure 3A a modified insulating element 40 is shown, which has two spaced apart webs 41 which extend essentially parallel to an end face of the filling elements 7. The two webs 41 are each provided on the outside with a laterally protruding arm 42 which can be clamped between a sealing strip 13 and the outside of a filling element 7. Between the two webs 41, a filling element 46 in the form of a connecting web is provided on the outside, wherein the connecting web can optionally be made of the same material as the webs 41 or of a softer material. The use of a softer material has the advantage that the insulating element can be pushed onto the bolts 8 more easily, since the filling element 46 has to be pierced when being pushed onto it. The bolt 8 can then be guided in an intermediate space 45 between the two webs 41. Optionally, a filling material or one or more connecting webs can also be provided in the space 45.

Each web 41 has an outwardly protruding projection 44 on the inside on the side facing the support profile 2, which protrudes to an end face of the filling element 7 and thus divides the space into individual chambers, even if these chambers are not completely separated from one another have to. The projections 44 can be made of the same material as the webs 41 or of a softer material.

An underside 43 of the arms 42 can optionally also be coated with adhesive, for the assembly, however, the fixation on the bolts 8 is sufficient without the arms 42 having to be glued.

In Figure 4A Another exemplary embodiment of an insulating element 50 is shown, in which only one web 51 extends essentially parallel to the end face of the filling elements 7. The web 51 is, however, no longer arranged centrally between the filling elements 7, as is the case with the Figures 1 and 2 was the case, but off-center. A first arm 52, which rests with an underside 53 on the outside of a filling element 7, thus protrudes essentially perpendicularly from the web 51. A second, shorter arm 54 protrudes on the opposite side and rests with an underside 55 on the outside of the filling element 7.

On the opposite inner side, two projections 56 and 57 are formed on the web 51, which are preferably made of a softer material than the web 51, the projection 56 being longer than the projection 57 on the bolt 8, since this is not hindered by a web, but the bolt 8 can be guided along the web 51 to the arm 52, which is then pierced during assembly or already has openings for the bolt 8 to pass through.

In Figure 5A a further insulating element 60 is shown that has two webs 61 which extend essentially parallel to the end face of the filling elements 7. The webs 61 are not completely straight, but rather curved slightly inward in the outer area. Furthermore, each web 61 is provided on the outside with an arm 62 which protrudes towards the filling element 7 and rests with an underside 63 on the filling element 7. On the inside, each web 61 is provided with a projection 64 which protrudes towards the end face of the filling elements 7. The webs 61 are held together by an elastic connecting web 66 which is W-shaped. Other geometries of connecting webs are of course also possible. During the assembly of the insulating element 60, it is pushed onto the bolts 8, the connecting web 66 being pierced. The webs 61 serve to guide the bolt 8.

In Figure 6A a further insulating element 80 is shown that has two outwardly protruding arms 81, with an underside 82 on the outside of one Lay out the filling element. In the case of this insulating element 80, no linear web is provided, but rather balloon-shaped chambers 83, 84, 85 and 86 which are filled with different materials are provided in the space between adjacent filling elements 7. On the inside, adjacent to the chamber 86, a V-shaped projection 87 is formed, the webs of which extend at least obliquely towards the end face of the filling elements 7.

On the outside of the chambers 83-86 insulating webs 88 are also provided, which are also provided with small projections 89 to divide the space between the end face of the filling elements 7 and the insulating web 88 into smaller chambers, which improves the thermal insulation.

The chambers 83-86 are filled with materials that can take on various functions. For example, one of the chambers can be filled with a material that foams up under the action of heat and thus seals the gap between the filling elements 7 in the event of a fire. In addition, one of the chambers can also be used to remove moisture or for other purposes.

In Figure 7A a further insulating element 90 is shown that essentially corresponds to the insulating element 80 of FIG Figure 6a corresponds without the balloon-shaped chambers 93 being provided with a filling material. In addition, the insulating bars 88 and 89 have been omitted. The balloon-shaped chambers 93 are connected on one side with a V-shaped projection 94 and on the opposite outside with protruding arms 91 which rest with an underside 92 on the outside of the filling elements 7.

In the Figures 6B and 7B no insulating glass pane with two glass panes is shown as the filling element 7 ', but three glass panes 70 are each positioned over two spacers 71, so that the insulating glass pane with three glass panes 70 achieves higher thermal insulation.

In Figure 8A a further strip-shaped insulating element 100 is shown, which has two spaced-apart webs 101, both of which extend essentially parallel to an end face of the filling elements 7. At least one filling material 104 is arranged between the webs 101, for example a foamed material which can easily be pierced by the bolts 8 during assembly. If several layers of a filling material are used the layers of the filling material 104 can be positioned in parallel or orthogonal alignment to the web web 101 and layered like a sandwich. There can be hollow chambers between the individual layers of the filling materials, whereby the layer structure can also begin with a material-free area.

The webs 101, on the other hand, consist of a harder material than the filling material 104 and can lead the bolt 8 from the inside to the outside. On the outside of each of the webs 101, an essentially at right-angled protruding arm 102 is formed, which rests with an underside 103 on an outside of a filling element 7 '. On the inside, each web 101 is provided with an outwardly protruding projection 105 which can preferably consist of a softer material than the webs 101 and which serves to improve the thermal insulation. A plurality of projections 105 can also be provided on the web 101.

In Figure 8B the installation situation of the insulating element 100 is shown that is essentially arranged between two filling elements 7 ′, which are designed as insulating glass panes with three glass panes 70. The filling material 104 is penetrated by several bolts 8, which are mounted at certain intervals on a groove 5 of the support profile 2. The projections 105 extend to an end face of the filling element 7 'and serve to improve the thermal insulation, it being possible for several projections 105 to be provided on the webs 101.

In the exemplary embodiments shown, the insulating elements 20, 30, 40, 50, 60, 80, 90, 100 extend essentially completely from an outside to an inside of the filling elements 7 or 7 '. It is of course also possible for the insulating elements to be slightly shorter than the end face of the filling elements 7 or 7 'or to be longer. Good thermal insulation is obtained if the insulating elements 20, 30, 40, 50, 60, 80, 90, 100 extend at least over 50%, preferably over at least 80%, of the length between the inside and outside of the filling elements. It is also possible that the length of the insulating elements is greater than the distance between the inside and outside of the filling elements; for example, the insulating elements can also extend up to the surface of the groove 5.

The various embodiments of the Figures 1 to 8 can be combined with one another in a wide range. For example, an insulating element with a web 21, 31, 41, 51, 61, 101 can also be provided with balloon-shaped chambers 83, 84, 85, 86 or 93, or the web can be provided with one or more of these chambers. In addition, it is possible to make the balloon-shaped chambers 93 open on an inner region, so that it is easier for the bolt 8 to be pushed through.

It can furthermore be useful to coat or glue each projection 105, 56, 57 but also each web 101 with a reflective material.
