Description

Connecting beams for fastening frame structures

The innovation concerns a connecting beam for fastening frame structures to each other or to adjacent walls.

There is often the problem of connecting frame structures such as window frames, large window frames or wall structures of winter gardens or their pitched roofs to other similar frame structures or to any solid masonry. The individual frames can assume a wide variety of angular positions in relation to one another. The angular positions that the frames assume in relation to one another or to an adjacent masonry are not determined by the connecting means with which they are connected to one another or to an adjacent masonry. The connection required for the above-mentioned structures has so far been designed and used on site in accordance with the requirements. Standard structures that are tailored and usable for all applications or at least for many applications are not known.

The innovation is therefore based on the task of proposing a connecting support of the type described above, with which frame structures, such as window frames or frames of conservatory walls or roofs, can be connected to one another or to adjacent masonry or the like in a stepless manner at all possible angles.

This task is solved in accordance with the innovation by a cylindrical middle piece, to which at least two independent angle pieces, each with one leg, are tangentially attached and which can be or are attached to the cylindrical middle piece in the desired rotational position by means of this attached leg. The cylindrical middle piece can be fastened with the front ends in the adjacent masonry or by means of any connecting piece with another middle piece to

Formation of a supporting framework. This makes it possible to form a supporting frame using a number of interconnected middle pieces that can absorb static forces. The two or more angle pieces arranged in the circumferential direction, one leg of which rests on the middle piece, can be rotated with this adjacent leg into any rotational position around the surface of the cylindrical middle piece, so that one angle piece can be used to connect to a frame to be fastened and the other angle piece to connect to adjacent masonry or to another frame. As can easily be seen, the frames can assume any angular position relative to one another or the frame to the masonry. In this way, it is possible to use a structural element that is always the same, namely the cylindrical middle piece with the angle pieces, as a connecting support for fastening the frame structures to be connected to one another. The individual elements of this connecting support, namely the cylindrical center piece and the angle pieces, which can also be identical to each other, can be stored by the meter and therefore only need to be cut to the desired length on site or in preparatory processing.

According to one embodiment of the innovation, it is proposed that the cylindrical middle section is designed as a metal tube. This makes it lighter, easier and quicker to work with and cheaper, without losing any significant amount of load-bearing capacity.

In addition, the innovation also proposes that the pipe be thick-walled. This has certain advantages for special fastening methods, with which the angle pieces are attached with one leg to the circumferential surface of such a pipe.

Furthermore, according to the innovation, it is proposed that the angle pieces are made of sheet metal and soldered, welded, riveted or nailed to the middle piece. These angle pieces can be made of sheet metal sufficiently stable and also very inexpensively.

Steel sheet of various qualities is particularly suitable for this. This steel sheet can also be galvanized to protect against corrosion. The thick wall of the pipe described above is particularly advantageous if one leg of the angle piece is to be riveted or nailed to the pipe. The thick wall is particularly advantageous if a free leg is to be nailed, because it is then possible to shoot the nails in a known way. If the pipe is relatively thin-walled, the pipe will be deformed at the shooting point and the nail seat will soon loosen. With thick-walled pipes, the pipe will not be deformed and the nail will not loosen. If the nail is thick enough, the two parts will probably be welded together when the nail is shot in, which will ensure that the nail sits securely and does not loosen.

According to a further development of the innovation, it is proposed that the tangentially adjacent leg of each angle piece has a round bend at its free end corresponding to the curvature of the pipe. This enables easy orientation of this leg on the pipe and easy adjustment to the desired angular position. In addition, the connection of this leg to the pipe is made easier as a result.

According to an alternative embodiment of the innovation, it is proposed that the tangentially adjacent leg of at least one angle piece protrudes beyond the point of contact and has a part bent at right angles to the middle piece at its free end, so that an extension of the outer surface of the angled part runs tangentially to the outer diameter of the middle piece, while a front edge of the angled part touches the outer surface of the middle piece. This also enables sufficient alignment of the angle piece on the pipe and at the same time there are satisfactory fastening or connection options for this leg of the angle piece to the pipe. However, the bend instead of the previously described round bend is easier to produce and thus allows this angle piece to be made cheaper in the

- 7 Manufacturing.

The new design then proposes that the tangentially adjacent leg be riveted or nailed with a double row. This makes the connection area wider and the connection more secure.

Furthermore, according to the innovation, it is proposed that each angle piece has a second leg that runs at right angles to the first leg and at a distance from the outer peripheral surface of the middle piece. This ensures that, in every angular position of the angle pieces relative to each other, there is sufficient space for connecting these legs to the frame parts to be attached. This distance can be increased or reduced depending on the dimensions of the frame parts of a frame construction that are to be attached to it. The cylindrical middle piece can always remain unchanged. In order to take into account the different cross-sectional dimensions of such frame legs of a frame construction, it is possible to keep angle pieces with different leg lengths in stock and to classify them according to the assigned cross-sectional dimensions of the frame constructions.

In addition, the innovation also proposes that the free end of the second leg has an angled piece pointing at right angles to this and the middle piece. This increases the bending and torsional rigidity on the one hand and defines a width with which this leg can be inserted into suitable dimensions of a frame part or an intermediate connecting piece on the other.

In addition, the innovation proposes that the angled piece is so wide that in the rotational position for a right-angled connection of two components to be connected to one another, the angled piece of one angle piece rests with its front side on the back of the first leg of the second angle piece. This simultaneously enables orientation using the simplest of means.

- 8 tation possibility created.

Finally, the innovation proposes that at least one angle piece extends continuously over approximately the entire length of a frame side to be attached. This means that only one angle piece needs to be sawn to length at a time, so that multiple cuts are eliminated. In addition, there is no need to align several such angle pieces longitudinally along the length of the pipe on site. In addition, such a single-story overall length is also more load-bearing and thus more resilient than a number of individual pieces.

The innovation will now be explained using an example in various arrangements.

Angle pieces

The basic structure of the connecting beam according to the innovation can be seen particularly clearly in Figures 1 and 6. In these Figures 1 and 6, a connecting beam of the type according to the innovation is shown in cross section. A side view is not necessary because the cross section shown only extends longitudinally over a desired length without any significant change.

The connecting support according to the invention essentially consists of the cylindrical middle piece, which is preferably designed as a metal tube 6. Figures 2, 3, 4 and 5 show this cylindrical middle piece 1 as a thick-walled metal tube 7. However, apart from the wall thickness, there is no difference between the thick-walled metal tube 7 and the metal tube 6. The diameter of the metal tube and the wall thickness dimensions can be adapted to the desired static load-bearing capacity of this tube 6 or 7.

To form the connection support according to the innovation, according to Figure 1, two angle pieces 2 and 3 are assigned to the pipe 6, the two legs 4 and 12 of which are at right angles to each other. This also applies to the two legs 5 and 13. In this arrangement, the leg 1 of the angle piece 2 and the leg 5 of the angle piece 3 lie tangentially against the pipe 6, each of the said adjacent legs having a round bend 8 at its free end, with which this leg follows the curvature of the pipe in the circumferential direction. The round bend can, for example, extend over an angle range of <15°. In this range, the leg 1 or 5 is then also connected or can be connected to the pipe 6. The connection can here

- &iacgr;&ogr; -

can be designed as desired.

The second leg 12 or 13 of the angle piece 2 or 3 is at a significant distance from the peripheral surface of the tube 6 in the radial direction. At its free end, each leg 13 or 12 has an angled piece 17 or 16. As can be seen in Figure 1, the width of this angled piece 17 or 16 is such that when the legs 13 or 12 are arranged at 90° to one another, e.g. in an arrangement according to Figure 1, the front side of the angled piece 17 comes to rest on the back of the leg 4 of the angle piece 2. The 90° position mentioned, which occurs very frequently, is therefore very easy to set without additional aids.

However, the connection of the angle pieces to the pipe 6 and the corresponding alignment of these angle pieces does not necessarily have to be done via the round bend 8. An alternative design to the round bend 8 is shown in Figure 6. Instead of the angle piece 2, an angle piece 9 is used there with a free leg 14 at a distance from the pipe, at the free end of which an angled piece 19 is provided, which corresponds to the angled pieces 16 and 17 already described.

The other leg 10, however, with which the angle piece 9 rests tangentially on the circumference of the pipe 6, does not have the round bend 8 at its free end, but rather an angled part 11 which is angled at right angles to the leg 10 and pointing towards the pipe 6. The bending is done in such a way that the outer surface of the angled part 11 runs tangentially to the circumferential surface of the pipe 6, with the width of the angled part 11 being such that the inner edge of the front side of the angled part 11 touches the circumferential surface of the pipe 6. This again makes it possible to easily align the angle piece 9 and, on the one hand, the angled part 11 and, on the other hand, the round bend 8 in the other variant ensure that the respective angle pieces 2, 3 or 9 can be aligned on the pipe 6 without any aids so that the legs 12, 13 or 14 each take up the necessary, but preferably equal, distance from the surface of the pipe 6.

To connect the innovative connecting beam shown in Figures 1 and 6 to a frame part of a frame construction, a leg 12, 13 or 14 could, for example, be connected directly to such a frame part on the one hand and, for example, to a wall on the other. In particular, however, connecting intermediate pieces 18 are generally used to connect to a frame part, with which the alignment of the frame part to the said legs of the angle pieces is made easier and at the same time the frame part is given a certain degree of flexibility in terms of its shape.

The structure and function of connecting intermediate pieces are already described in DE-G 87 08 611. Such connecting intermediate pieces 18 have grid webs 20 which engage in corresponding longitudinal slots in a spar profile of a window frame or other frame and thereby provide stability to the frame in the manner described in the utility model mentioned.

The embodiment of the innovative connecting support shown in the drawings has angle pieces 2, 3 and 9, in each of which the leg 12, 13 or U arranged at a distance from the pipe surface is inserted between two opposing grid webs 20 of the connecting intermediate piece 18 in the manner shown in all figures. In this arrangement, the said legs can be connected in any suitable manner to the connecting intermediate pieces 18, for example by means of centrally inserted sheet metal screws.

In Figures 2 to 5, the arrangement of the connecting support according to the invention for fastening different elements at different angles to one another is shown in cross-section in various embodiments. Figure 2 shows a corresponding cross-section in which a window frame or a conservatory frame is connected to the connecting intermediate piece 18 via a longitudinal frame beam 21 in the manner already described and known and is stabilized via its grid webs 20. A thick-walled tube 7 is provided here as the cylindrical middle part of the connecting support, to which

(IMI ··

&bull; » · &diams;&igr;

- 12 -

in the manner already described, angle pieces 2 and 3 are fastened. The fastening is carried out here by shooting a row of nails 22 into each angle piece 2 and 3. The use of a thick-walled tube 7 has proven to be particularly advantageous for shooting in the nails 22.

In the embodiment according to Figure 2, the frame with the longitudinal frame beam is to be connected at an angle of 5o to the masonry 23 shown in cross section. For this purpose, the longitudinal frame beam 21 is connected to the connecting intermediate piece 18 in the manner described, the grid webs 20 of which give the longitudinal frame beam 21 the necessary stability against bending, for example due to wind pressure against the glass pane 2t . On the side of the connecting intermediate piece 18 opposite the longitudinal frame beam 21, the leg 13 is inserted between the grid webs 20 and in this arrangement the leg 13 can be connected to the connecting intermediate piece 18 in any way. The other leg of the angle piece 3 is placed on the metal tube 7 in the manner already described and fastened by means of a row of nails 22 shot into it. The metal tube 7 itself can be attached at both ends in any way to a roof structure on the one hand and to the foundation on the other. However, it can also be part of an overall frame construction and connected at one end or at both ends with connectors of any design but suitable to another such tube as a cylindrical middle piece for another corresponding connecting support, which runs, for example, in a horizontal direction.

To connect the longitudinal frame beam 21 to the masonry 23, the further angle piece 2 is now attached to the pipe with its leg & also by a row of nails 22 in such a rotational position that the further leg 12 runs parallel to the masonry 23 and can be attached to the masonry 23 in this position, for example by doweling. The attachment can be made directly to the masonry or to a piece attached to the masonry or built into the

t * * i

The bracket 25 is embedded in the masonry. The fastening thus made can then be covered by any cladding shown in Figure 2 but not specified in more detail.

In Figure 3, a very similar cross-section to that in Figure 2 is also shown as an attachment to a masonry 23. However, the attachment should now no longer be at an angle of 5° but at an angle of k$o to the masonry 23. It can be seen here that the arrangement of the angle piece 2 in relation to the masonry 23 is unchanged. However, the angle piece 3 is pivoted on the pipe 7 by a further 40° compared to the illustration in Figure 2 and only then is it attached to the pipe 7. In Figure 3, too, the grid webs 20 of the connecting piece 18, which are also not designated, engage in corresponding longitudinal grooves of a longitudinal frame beam 26 with a slightly different cross-section in order to stabilize this in the manner already described and to attach it to the masonry 23 via the connecting support consisting of the angle pieces 2 and 3 and the pipe 7.

Figure 5 again shows a cross-section very similar to the cross-sections in Figure 2 and Figure 3. According to Figure 5, however, not one frame is attached to the masonry, but rather two frames are attached to their adjacent longitudinal frame beams 27 and 28 in any arbitrary angular position to each other using the new connecting support. Here too, as can easily be seen in Figure 5, the respective angle piece 2 and 3 is only rotated on the pipe 7 into the required rotational position in order to be able to be inserted into the connecting intermediate pieces 18 in the manner already described. The connecting intermediate pieces 18 are then in turn connected to the longitudinal frame beams 27 and 28 in the manner already described. It is also noteworthy here that according to the embodiment shown in Figure 5, the angle piece 2 is attached in the area of the round bend of the leg resting on the pipe 7 with two rows of nails 22 running parallel to each other. The frames formed from the longitudinal frame beams 27 and 28 can be frames of a known type. The cross-sectional design of these frames is not the subject of the innovation and therefore does not need to be described here.

In this regard, reference can be made to the known state of the art.

Figure k shows the use of a connecting beam according to the innovation when fastening or connecting a vertically standing frame of a winter garden to a sloping roof frame construction of a winter garden.

In contrast to the previously described embodiments, the cross-section of the pipe 7 shown in Figure 4 with the angle pieces 2 and 3 arranged on it shows this pipe 7 in a horizontal position. The angle piece 2 of the pipe 7 is attached to the pipe 7 in the manner already described in such a position that it is in turn connected to a horizontally running frame longitudinal beam 29 via the connecting intermediate piece 18. In this case, the angle piece 2 can in turn be connected to the connecting intermediate piece 18 via a series of sheet metal screws 30. The frame longitudinal beam 29 is part of a large frame that forms the glass wall of a winter garden. A rain gutter 31 can be attached in the usual way to the upper outer front of this glass frame. A roof structure 32 opens into this rain gutter 31, which is essentially formed from a frame structure in which glass panes 33 are held. An associated beam 34 of such a frame can now in turn be connected to an intermediate connecting piece 18, which in turn is connected in the manner already described to the angle piece 3, which in turn is fastened in the appropriate angular position to the metal tube 7. This again creates a secure connection between the associated beams 34 and 29.

Figure 7 shows a simplified embodiment which essentially corresponds in structure to the embodiments according to Figure 1 or Figure 6. A metal pipe 7 is equipped with angle pieces ²¹ and 3', as described with respect to Figures 1 and 6 with respect to the metal pipe 6 and the angle pieces 2, 3 or 9. The embodiment according to Figure 7 is, however, simplified compared to the embodiments according to Figures 1 and 6 in that in the embodiment according to Figure 7 no additional connection is required for a further connection.

A separate connecting piece 18 is required. Rather, in the embodiment according to Figure 7, the second leg 12' or 13' of the angle pieces 2" and ³¹ is already formed as one half of the previously described connecting piece 18 by the formation of the grooves 35 and 36. The other half is formed by a flat profile 37, which has the grooves 38 and 39 in a corresponding arrangement and is connected to the second leg 12' or 13' of the angle pieces 2' or 3' in such a way that parallel hollow chambers are created which are open to the outside in a known manner via longitudinal slots 40 or 41. This flat profile 37 then in turn has the grid webs 42 which run parallel to one another at a distance and correspond to the grid webs according to Figure 6, for example. This simplifies the overall structure without any loss of stability compared to the embodiments according to Figure 1 and Figure 6 and also makes it cheaper due to the lower material requirement - a flat profile is completely eliminated. and lighter overall. In addition, the assembly work on site with which the connecting pieces 18 according to the embodiments of Figures 1 and 6 must be connected to the associated angle pieces is eliminated. If, however, the last-mentioned advantage is dispensed with, it is also possible to always provide the respective side legs of the angle pieces with grooves 35 and 36, in contrast to the illustrations in Figures 1 and 6. The presence of these grooves 35 and 36 is not detrimental to the use of the connecting piece 18 according to the embodiment in Figures 1 and 6, so that if the grooves 35 and 36 are always present in these free legs, either a connecting piece 18 or a corresponding flat profile 37 according to Figure 7 can be used, whereby any special features specific to the construction site can be taken into account.

It must be particularly pointed out here that it is not absolutely necessary for the cylindrical middle pieces to be attached to a brickwork or other constructions at their front ends to absorb static forces. Rather, these cylindrical middle pieces I can be connected to one another to form a frame construction, which as such can absorb the occurring

- can absorb 16 static forces.

The innovative connecting beam is a construction element that makes it possible to securely connect frame structures, such as those found in windows, window walls or conservatories, at almost any angle. These innovative connecting beams can in turn be connected to external components that absorb static forces, or they can be assembled with one another to form a frame structure that can then absorb the static forces that occur. The connecting beam is extremely easy to manufacture and store, and its dimensions can be easily adapted to the forces that occur.
