Description

Window band with spacer elements

The innovation relates to a window band containing at least two adjacent window frames or door frames or a combination of at least one window frame and one door frame, wherein adjacent beams of adjacent frames are connected to one another via a support which, for each of the said beams, has two grid webs running parallel at a distance from one another, which are enclosed by the associated beam at least on their outside or inside.

Window bands of the type described, in which two or more window frames or combinations of window frames and door frames are immediately adjacent to one another and must be held in this position without the possibility of attaching the window frames to the masonry in this area, are quite generally known. Suitable supports for this have already become known with the DE-G 87 08 611- The adjacent arrangement of frames mentioned here can also be taken from the drawing belonging to this utility model.

The ends of such supports known from the utility model mentioned can be attached to other supporting scaffolding or to the adjacent masonry using suitable fastening means. Suitable fastening means for this are already known from DE-G 88 11 361.

The fastening of such frames arranged directly next to one another using the above-mentioned supports and the fastening means for these supports has proven to be very effective. However, the frame beams held by the support lie parallel to the support, so that a longitudinal expansion of the frame beams running at an angle to these supports would no longer be possible without special additional measures. If the frame were to heat up, this would lead to the above-mentioned angled beams buckling. To avoid this,

With such frame fastenings, a suitably long piece is notched out at the top and bottom of the beam running parallel to the support, so that in this area there is a bending option for the notched beam. This allows the beam arranged at an angle to it to expand without bending and in doing so bends the notched area of the beam running parallel to the support accordingly.

u This practice has also proven successful, but is laborious and

% necessarily forces a corresponding

% Damage to the spar profile. At the same time, this also

The side guidance of the beam profile is lost in this area due to the grid bars of the beam, because this area of the beam profile has been removed. In addition, the notching of the beam is usually carried out on site, i.e. at the construction site. Since it is done by hand, the person carrying out the work tends to ' to notch as little as possible, so that there is a risk that the notch area becomes too small and therefore correct bending cannot take place in the event of thermal expansion, but instead the angled beam buckles or bends slightly, which permanently loosens the brackets and permanently destroys the seals.

Based on the state of the art described above, the innovation is based on the task of proposing the construction of a window band in which the necessary expansion option can be provided with very simple means and thus very inexpensively.

This object is achieved according to the invention in a window band of the type described at the outset in that at least one spacer element is arranged as a spacer between the beam and the support at a distance from the respective beam end, the distance being dimensioned such that the free beam end can bend sufficiently in the event of a change in the length of the beam arranged at an angle to it, without the angled beam buckling.

**l ft·* ♦ f · &iacgr;

By inserting spacer elements as distance holders, it is no longer necessary to notch any beams in the area of the beam edges. The frames can be installed without any rework. The spacer elements that function as spacers are simply inserted in the appropriate position beforehand and attached to the support in any way . The corresponding beam of a frame can then simply be pushed against these spacer elements. This is extremely quick and no rework is required on site.

According to one embodiment of the innovation, it is proposed that the spacer element is designed as at least one plate of a certain thickness with side edges running at right angles to one another, the width of which is such that the plate fits between the grid bars and can be clamped between them. This is particularly advantageous because, with such a choice of dimensions, the spacer elements can easily be pressed between the grid bars and are held in place by them. Any additional fastening means or fastening measures can therefore be completely dispensed with.

A further development of the innovation provides that the spacer element is rectangular, with the length and width of the side edges being dimensioned such that the spacer element can be clamped between the grid bars of two ^girders of different dimensions depending on the rotational position. The dimensions of the girders and thus the width of the grid bars depend on the load they have to bear and thus ultimately on the size of the area enclosed by the frame to be attached. In practice, therefore, different sizes of such girders are provided in certain stages. The rectangular design of the spacer element can now be dimensioned in the edge dimensions so that the spacer element fits two different sizes of such girders, depending on the rotational position . This can reduce the number of different sizes of spacer elements and thus their production costs. In addition, handling and storage on the construction site is simplified.

In addition, the innovation also proposes that at least one plate of a spacer element has a spring-elastic element on at least one side edge to generate a clamping force. This makes it easy to compensate for inaccuracies in the spacing of the grid bars and in the dimensions of such spacer elements or plates, and such a plate or spacer element can still be easily inserted and clamps itself in place automatically.

It is particularly advantageous if - as proposed in a further embodiment - all four side edges have a spring-elastic element. This doubles the range of tolerable inaccuracy in the distance dimensions.

In a further development, the innovation proposes that each spring-elastic element be designed in the form of an open or closed bracket, which is connected to the plate with at least one end of the bracket directly or via a short web. This design is particularly easy to manufacture as a spring-elastic element, whereby if the end of the bracket is to be connected to the plate directly, i.e. without a web, the form of an open bracket is probably preferable.

In addition, the innovation also proposes that at least the outer edge of each bracket should be such that the outer dimensions of the side edges widen towards the middle of the bracket. This can be done, for example, by having such a bracket, open or closed, curved outwards. This makes it easier to insert such a spacer element and thus simplifies its handling. This also applies if, as further proposed, the outer edge of each bracket has an attachment.

In the case of a bracket that is open in the middle of the bracket, the innovation proposes that each open end of the bracket be followed by another bracket section of approximately the same length, running in the opposite direction and at an angle, so that

that an accordion-like, elastic area is created. Such a spacer element or plate is cheap to manufacture and can be inserted very easily, so it is easy to handle. The spring travel is relatively large, so that correspondingly large inaccuracies can be tolerated.

In a further development, the innovation proposes that each plate has a through hole in a mirror-symmetrical arrangement to the center of the plate and a protruding pin on one side, whose diameter is dimensioned to match the through hole and whose protrusion reaches a maximum of the plate thickness. In this way, it is possible to produce plates with a certain standard thickness and to stack two or more plates on top of each other using the hole-pin connection and to connect them to each other, so that spacer elements of different thicknesses can be produced by using a different number of plates. This makes it possible to produce spacer elements of different heights while still using the same standard components. This achieves a high level of flexibility with the cheapest construction and the simplest application of such parts.

Finally, according to the innovation, it is also proposed that each plate is made in one piece and is made of elastically deformable plastic. This is a particularly simple and therefore quick and easy construction of such a plate, whereby such a simple construction also makes handling of such a plate on the building site much easier. Suitable elastically deformable plastics are known in large numbers and are inexpensive. Such plastics have all the required elastic properties that are necessary for the use of such a plate.

The innovation will now be explained in more detail using examples.

Figdr 1 shows an arrangement of two window frames 31 and 32 arranged one above the other and a door frame 33 arranged to the side. On the free side of the door frame 33, for example, there could again be window frames 31 and 32.

Between the beams 35 and 38 of the window frames 31 and 32 on the one hand and the beam 39 of the door frame 33 on the other hand, a support k, which is also known per se, is arranged in a known arrangement and is connected to the frame 32 by means of a spring 40.

in the masonry «U. Such a support 4 can also be provided on the beam of the door frame 33 opposite the beam 39, so that further doors or windows can be connected there. It can also be provided on the beams opposite the beams 35 and 38 of the window frames 31 and 32, so that further door frames or window frames can also be connected there. In the embodiment according to Figure 1, it is additionally provided in a horizontal arrangement between the beams 36 and 37 of the window frames 31 and 32.

As can be seen in Figure 3, the horizontally running beam 3* of the window frame 31 and the horizontally running beam 5 of the door frame 33 have a distance 42 from the masonry 41, so that the beams mentioned, which are arranged at an angle to the beams 35 and 39, can be wedged there. If the angled beams 34 on the one hand and 5 on the other hand expand, it is necessary that at least the beam ends 2 of the beams 35 and 39 can bend accordingly, i.e. are designed to be flexible accordingly. According to the innovation, this is achieved quite simply by inserting a spacer element 3 between the beam 35 or 39 and the support 4 at a suitable distance 1 or Γ - this is to indicate that this distance does not have to be maintained exactly. Whether one such spacer element or several such spacer elements are used depends on the length of the respective spar. For short spars, one spacer element is usually sufficient. If two spacer elements are used, the distance 1 or Γ could be too short, which would result in the forces being too great if the spars 3* or 5 were to be stretched, so that there would be a risk that the spars 34 and 5 would themselves buckle.

When using the spacer elements 3, it is not necessary to ensure that they are arranged at the same height, provided they are arranged on opposite sides of the support 4. They can be arranged at completely different heights. For example, in the arrangement according to Figure 1, a spacer element 3 is inserted at a sufficient distance from the upper and lower free beam end 2 of the beam 35 of the window frame 31. The same applies to the beam 38 of the window frame 32. On the opposite side, however, only one spacer element 3 could be inserted at a sufficient distance 1' at the upper and lower beam end 2 of the beam 39, so that there would only be 2 spacer elements in total. In this case, the distances 1 and Γ would also be different.

The beams 36 and 37 of the window frames 31 and 32, which run horizontally, could, however, be supported against the support * with three evenly distributed spacer elements 3 (no longer designated here). However, in the embodiment according to Figure 1, the distance between the spacer elements 3 and the respective end of the beam 36 could also be chosen to be greater than that of the beam 37, because the beam 36 has to bend more than the beam 37 due to the greater length of the beam arranged at an angle to it at the same temperature increase. With this arrangement, the necessary expansion compensation is also possible if the upper beam 3* of the window frame 31 and the opposite lower beam of the window frame 32 (not designated in more detail) are rigidly wedged along their entire length, so that a bending to compensate for expansion cannot take place there.

The spacer elements 3 themselves have a sufficient thickness 7 to create enough space for the necessary bending. Their dimensions are such that they can be easily inserted between the grid bars 10 and 11 of a carrier 1 and are held in place there, preferably by clamping. The installation position of these spacer elements 3 is clearly visible in Figure 2.

In order to produce as few different designs of spacer elements 3 as possible, the use of a rectangular plate 6 with a certain thickness 7 is proposed as the basic element for the manufacture of a spacer element 3. A single plate 6 with a thickness of 7 then makes it possible to create the minimum distance for expansion compensation. If a larger distance is required, these plates 6 can be stacked on top of one another to the desired extent, thereby producing a spacer element 3 of a different thickness. Such a plate 6 is shown in plan and side views in Figure 4. The plate 6 has a square basic shape and can have an opening 43 in the middle that is also square and is rotated by 45° compared to the outer square. This opening 43 is so large that the narrowest webs up to the outer edge of the plate 6 are so narrow that they can be deformed by hand with strong pressure. Such a

Plate 6 has a thickness of 30 mm and can be inserted between the grid bars 10 and 11, which are also shown in Figure 4 for plate 6. With regard to the distance between the grid bars 10 and 11, the square plate 6 can preferably have a small oversize, so that it has to be slightly compressed in order to be able to be inserted between the grid bars 10 and 11. This compression is done elastically, so that the plate 6 is clamped between the grid bars 10 and 11 after insertion. If necessary, several of these plates 6 can be stacked on top of one another to change the distance.

Preferably, however, such plates for producing a spacer element 3 are rectangular and have the side edges S and 9 of correspondingly different lengths. This embodiment is shown in Figure 4 with the designations 6.1 to 6Λ. The rectangular shape of such plates has the advantage that the edge lengths 8 and 9 can be dimensioned such that, depending on the rotational position, they fit between grid webs 10 and 11 that are at different distances. This means that one and the same plate can be used for two different supports 4 with different distances between the grid webs 10 and 11.

The rectangular plates can also be stacked on top of one another to produce spacer elements 3 of different thicknesses. To facilitate this process, each plate 6.1 to 6Λ has a through hole 27 arranged at a distance and symmetrically to the plate center 26 and a cylindrical pin 28 extending on one side. The cylindrical pin 28 has a projection 29 which is at most equal to the plate thickness 30 of these plates. The diameter of the cylindrical pin 28 is dimensioned such that it fits into the through hole 27 with slight pressure. This holds the plates stacked on top of one another together, making handling of a spacer element 3 assembled in this way significantly easier. If required, these plates can also have a central hole 44.

In the embodiments, the plates 6.1 and 6.2 have closed brackets 12 and 13 on their four side edges, while the

f embodiment according to 6.3 and 6.4 have brackets 14 and 15 which are in the

ti are cut in the middle, i.e. are open.

% In embodiment 6.1, the brackets 12 have on their outer edge

|1 19 has an attachment 22. The ends 16 of the bracket 12 are

*£ connected to the actual plate body via webs 18, so that

: Plate 6.2 has a very similar design. Here

ji however, the outer edge 20 of the wing 13 does not have an attachment

', as in embodiment 6.1. Rather, this outer edge 20

;.. of the bracket 13 is curved outwards, whereby the same effect is achieved

■p is'like with the attachment of the bracket 12.

- So that the plate 6.1 or 6.2 can be inserted between the grid bars 10 and 11, the brackets 12 or 13 are simply deformed slightly inwards by hand so that the two side edges 8 or 9 - depending on which bracket is bent - come closer together and can thus be inserted between the grid bars 10 and 11, which are spaced apart accordingly. The brackets then spring apart again elastically so that the plate 6.1 or 6.2 is clamped between the grid bars 10 and 11.

The embodiment 6.3 is very similar to the embodiment 6.2. In the embodiment 6.3, however, the brackets 14 are separated in the middle, so that there are open brackets there. The outer bracket ends 17 are again attached to the actual plate body via a web 18. Here too, at least the outer edge 21 of each bracket 14 is curved or inclined and there is again an opening (not specified) between the bracket 14 and the actual plate due to the webs 18. Here too, each bracket 14 can be pressed inwards and the plate 6.3 can thus be easily inserted between the grid webs 10.

outside, so that the plate is clamped in the manner already described several times.

A further embodiment is embodiment 6.U, which again largely corresponds to embodiment 6.3. Here, too, there is an open bracket 15, which is however attached directly to the actual plate body without the use of a web 18. Here, too, the bracket is inclined or curved outwards, so that there is also a not very large clearance or a corresponding opening between the bracket and the plate, which allows the bracket to be deformed inwards towards the plate.

At the point where the open bracket 15 is separated, a further bracket piece 23 is attached in the opposite direction and with the opposite inclination, which has a length of 2h , which corresponds approximately to the length of the bracket part underneath. This creates an accordion-like structure with which an enlarged elastic area 25 can be created. The use of such a plate 6Λ between the grid webs 10 and 11 is then again as already described several times.

Figure 2 clearly shows the installation arrangement of such plates for the production of spacer elements 3. There, a frame arrangement in the OllPrvhnitt o*»7i»iot_ h«»i Her fin Hr»lm IS nnH oir> HnIm IQ icioKe aiu-K -^ _{o o} - ₇ . &mdash;&mdash; .,, ,_.-.._ _&mdash;»...

Figure 1) is held by a support 4, as described in DE-G 87 08 611. On both sides, between the beam and the support, inserted between the grid webs 10 and 11, one or more spacer elements 3 are inserted at a suitable distance from the respective beam end. As a result, the corresponding contact edges of the beams 35 and 39 no longer come into direct contact with the support ^, so that a bending space is created with which an expansion of the beams arranged at an angle to the said beams can be absorbed. The connection area of the two beams can be covered by a cover profile 45, as also already described in DE-G 87 08 611.

With the innovative means, it is possible for the first time to ensure the necessary expansion capacity in such frame systems in a simple, inexpensive and reliable way and on a permanent basis.
