Description

The invention relates to a holder for supporting a pipeline on a component in the form of a profile support, wherein between the pipeline and the profile support there is arranged a component in the form of a bearing foot which at least indirectly supports the pipeline, is fixed to a flange of the profile support and extends essentially perpendicular to the profile support, wherein the holder for mutually fixing the two components has at least on one side of the first of the two components a clamping jaw which at least indirectly surrounds the first component and on the opposite side thereof an abutment for the clamping jaw which also at least indirectly surrounds the first component, and wherein the holder engages the second of the two components.

As a rule, the movable bearing foot is attached to the stationary profile beam, i.e. the clamping jaw grips the flange of the profile beam and fixes the bearing foot vertically against the flange. However, it is of course also possible to grip and clamp the bearing foot using the clamping jaw and the abutment and to fix the flange of the profile beam to it. Profile beams in the form of T-beams or double T-beams as well as bearing feet in the form of roller bearing housings or bearing slides, which can also consist of simple T-beams, are used for the storage of pipelines. In the latter case, the pipeline can be fixed to the bearing foot using welded pipe clamps, for example.

The clampable brackets known in the state of the art for supporting a pipeline generally consist of a clamping groove welded to the underside of the bearing foot, which acts as an abutment and which grips around the flange of the profile beam on one side, as well as a clamping jaw that grips around the opposite edge of the profile beam flange. This clamping jaw also grips the bearing foot and secures it against the profile beam by gripping the bearing foot on both sides and clamping it using a clamping screw. The bearing foot is thus secured to the profile beam on one side of the profile beam flange via the welded abutment and on the other side of the flange via the clamping jaw.

However, this type of pipe support has the disadvantage that the clamping screw only ensures that the clamping jaw is clamped to the bearing foot, but there are no means available to clamp the clamping jaw against the abutment; because the bearing foot is only pushed against the profile support with its abutment, which forms a clamping groove, whereupon the clamping jaw is placed on the bearing foot from the other side of the flange and also pushed against the profile support and is clamped against the bearing foot in this manually clamped position. The known brackets therefore lack the ability to clamp the component gripped by the clamping jaw - in this case the profile support - which means that the two components cannot be sufficiently securely fixed together.

Based on this, the present invention is based on the object of providing a clampable holder for supporting a pipeline, which ensures that both components are fixed together without play by clamping them together.

This object is achieved according to the invention in that the clamping jaw has a recess for receiving at least one edge with play

of the second component and is pivotably mounted via the recess about an axis substantially parallel to the first component, and that the clamping jaw carries a clamping means and is supported against the action of the clamping means about the pivot axis against the first component and via its recess against the second component.

This results in the advantage that a clamping device actuation both secures the second component via the recess edge and clamps this first component via the clamping jaw area that encompasses the first component.

The two components are fixed together by first tilting the recess on the component held in the recess by pivoting the clamping jaw about its pivot axis. This creates a frictional connection between the clamping jaw and the component held in the recess, which secures the clamping jaw to this component. The clamping jaw can now be clamped against the other component using the clamping device, whereby both components are secured against each other and also to the opposite abutment while the clamping device is being operated.

The correct choice of recess size is essential here: Firstly, the clamping jaw must be able to be easily placed over the recess onto the edge of the second component, i.e. with play; Secondly, this play should only be so large that pivoting the clamping jaw immediately causes the recess edges to tilt on the second component, thus securing the clamping jaw against the second component. This means that the recess should accommodate the second component with play when it is not clamped, but when pivoted and later clamped, it should rest against the second component without play and even clamp it in place.

As with the prior art brackets, the component accommodated in the recess of the clamping jaw and the component acted upon by the clamping device can be exchanged here, i.e. the positioning of the clamping jaw and the abutment can be rotated by 90°. With regard to the stability of the profile support and the ability to move the bearing foot on it, it is however expedient if the first component is the profile support and the second component is the bearing foot, whereby at least the edge of the bearing foot is accommodated in the recess of the clamping jaw and the clamping device fixes the clamping jaw via its recess to the bearing foot and this to the profile support and both to the abutment.

In any case, it is advantageous if the pivot axis is formed by one of the horizontal recess edges and, expediently, by the edge resting on the second component after the clamping jaw has been attached, which edge generally runs parallel to the longitudinal extension of the first component to be clamped.

As far as the clamping device is concerned, this can either act on one of the two components directly or at least indirectly, or it can also be connected to the opposite abutment and act on it. The first case of acting on one of the two components is particularly advantageous from the point of view that the clamping jaw can remain independent and separate from the abutment and therefore the width of the first component, usually the profile beam, is irrelevant for the quality of the clamping. This is particularly recommended when working with different profile beam widths and an excessive variety of clamping screws is to be avoided.

However, the design of the clamping screw connecting the clamping jaw and the abutment is simpler and easier to clamp, whereby in this case the clamping screw is expediently screwed to a clamping nut after passing through a hole provided in the abutment. However, it is also important here that the clamping jaw pivots around the pivot axis during the clamping movement and is thus simultaneously secured to the second component.

In order to increase the force transmission of the clamping device to the two components, the clamping jaw conveniently carries the clamping device acting on one of the two components on the side of the bearing foot facing the profile support. This makes it easy to transfer an infeed movement of the clamping device to the already tilted clamping jaw and fix it by increasing the distance between the clamping jaw and the component acted upon by the clamping device, which can be done easily using a clamping screw, for example.

The effect of tilting and subsequent jamming on which the invention is based is exploited in particular by providing a spacer element between the first and second components, which, due to the increased distance between the clamping jaw recess and the contact area on the first component, leads to a greater leverage and a correspondingly increased contact force of the clamping jaw. In order to be independent of the carrier width with regard to the spacer element, it is recommended that the spacer element only extends over partial areas of the overlap area of the two components.

Advantageously, the spacer element is connected to the clamping jaw and/or the abutment, whereby the position of the spacer element can be determined during assembly in relation to the clamping jaw or the abutment, in order to reduce the number of individual mounting parts.

Ie to achieve this. In particular, the spacer element can consist of bent clamping jaws or abutment tongues, which in the case of T-shaped bearing feet have to be cut out of the clamping jaw/abutment material anyway in order to provide space for the T-shaped center bar.

Another way of fixing the position of the spacer element can be achieved by enclosing one of the two components at at least one edge, whereby care must be taken to ensure that this bent area does not collide with the clamping jaw or the abutment.

As far as the abutment is concerned, it is expediently designed in a hook-shaped manner to form a clamping groove or is arranged at an angle to the component to be clamped in order to be able to clamp and fix this component in the groove or in the tapered area both vertically and horizontally.

The simplest way is to weld the abutment to the second component, i.e. in particular to the bearing base. However, in order to be as flexible as possible when using the profile support and bearing base and their fixing position and to be able to use both parts for both fixed and sliding bearings, they should not have any permanently attached projections on their flange surfaces. It is therefore particularly advantageous if the abutment is designed in a similar way to the clamping jaw, namely also has a recess for receiving at least one edge of the second component and is pivotably mounted via the recess about an axis that is essentially parallel to the first component. This also allows the abutment to be fixed to the second component by frictional tilting, in that the clamping device of the clamping jaw moves the second component relative to the first component as a result of its feed movement. During this assembly and fixing process, care must be taken to ensure that the abutment is actually tilted by following the sliding movement.

This advantageously results in the two components being fixed to one another in such a way that the abutment is supported against the action of the clamping means of the clamping jaw about the pivot axis against the first component and via its recess against the second component.

In the advantageous design of the abutment, this differs from the clamping jaw only in that it does not have its own clamping device, in order to simplify assembly by only having to use clamping devices on one side of the bracket. However, another clamping jaw can also function as an abutment, especially if it is not possible to move the bearing foot on the profile support - for example due to a pipe already resting on it. In this case, it is possible for this additional clamping jaw, which functions as an abutment, to have its own clamping device, but a common clamping device can also be provided that connects the abutment and the clamping jaw in the manner described above and secures them against each other.

A screw can be used in particular as a clamping device, whereby in the clamping device acting on one of the two components, the clamping jaw has a bore with an internal thread that interacts with the clamping screw, while in the clamping device connecting the clamping jaw and the abutment, a bore without a thread is provided in both elements and the screw head on the side of one element and a screw nut on the side of the other element act as a stop.

In addition to the clamping jaw design with one recess, a second variant can also be used advantageously: Here, the clamping jaw has two recesses one behind the other in the direction of the second component and the clamping jaw is fixed to the

·**« m φ λ mm

second component by anchoring it frictionally to one edge of the recess. These two recesses allow a certain form fit between the clamping jaw and the second component during assembly, although here too the second component extends through the two recesses with some play so as not to hinder placement and yet to enable subsequent anchoring. In both embodiments it is therefore expedient for the clamping jaw to be able to be loosely attached to the second component when not being acted upon by the clamping device. It is also advantageous if the clamping jaw grips the second component at both edges in order to distribute the clamping force evenly across the cross section and to also obtain a form fit in the transverse direction to the second component before clamping. In particular with a wide clamping jaw designed in this way it is also advantageous if the clamping jaw has two clamping devices, each of which is assigned to a separate edge of the second component. This allows the clamping force per clamping jaw to be increased further.

In the same way, however, a clamping jaw of the type described can also be designed in two parts, i.e. only encompassing a single edge of the second component, i.e. in particular the bearing foot, whereby one is also independent of the width of this second component.

To increase the clamping force, it is also advantageous if an intermediate bracket is provided between the clamping jaw and the first component, which can be acted upon at least indirectly by the clamping device and which grips around the edge of the first component on the side of the clamping jaw to form a clamping groove. This allows a better transfer of the clamping force to the first component than if it were acted upon directly by the clamping device, for example by the clamping screw; on the other hand, a further lever ratio can be created.

•jfl ··· ··· ·

IV ··· ■· ·«· ac ·· <■

and increase the clamping force generated by the clamping device according to the lever ratio.

The intermediate bracket can be designed in the same way as the clamping jaw or the abutment and have a recess for receiving the second component and can be pivoted via the recess about an axis that is essentially parallel to the first component. This allows the same advantages to be achieved that were already mentioned above in connection with the clamping jaw and the abutment. Here too, it is recommended that the intermediate bracket grips the second component on both edges to improve the positional fixation.

In an advantageous manner, the intermediate bracket can also be designed to be resiliently flexible in order to be able to maintain the quality of the clamping together with the clamping jaw, which is also expediently designed to be resiliently flexible, and the corresponding abutment even when oscillating or swelling loads are transferred to the bracket as a result of temperature fluctuations in the pipeline.

In any case, it is essential that the clamping jaw is secured to the second component by its frictional tilting at the edges of the recess. In addition, the clamping jaw must be positioned at an angle to the side of the first component facing away from the second component for horizontal and vertical fixation, or the clamping device must act on it at an angle. This is the only way to achieve a clamping that is equally strong in all directions.

In particular for the clamping jaw, but also for the intermediate bracket and the abutment, it is recommended that they be constructed from a sheet metal blank, the shape of which can be easily achieved by bending or similar.

&bull; «· «like fet ····

In addition to the ease of processing and the material savings, the use of sheet metal blanks also makes it possible to achieve the elastic flexibility described above.

As far as the bearing base is concerned, it is advisable if it consists of a T-profile support, at the free central end of which means for receiving and securing the pipeline are arranged.

Various embodiments according to the invention are possible for the clamping jaw: Firstly, the clamping means can be arranged at one free end of the clamping jaw and the recess at the other free end, whereby the area between the two free ends of the clamping jaw serves to engage the first component. In this variant, the clamping means conveniently engages the second component. However, it is also possible that it is not the area between the two ends of the clamping jaw that engages the first component, but the clamping means itself. This engagement can advantageously take place by interposing the intermediate bracket, which is arranged in the manner described above to equalize and increase the contact force.

Finally, the clamping device can be arranged at one free end of the clamping jaw, the area encompassing the first component at the other free end and the recess in between.

In the design of the clamping jaw with two recesses, it is also recommended that the clamping device is provided at one free end of the clamping jaw, that the clamping jaw rests with its other free end on the first component, and that the two recesses are arranged in the area between them, with the clamping device engaging the second component.

Finally, it is advantageous if the clamping jaw has an angled tab that carries the clamping device, whereby the tab is expediently connected to the clamping jaw in one piece via one of the recess edges. This tab can also serve to attach the spacer element to it, thereby positively connecting it to the clamping jaw.

It is also recommended that the clamping jaw is provided with ribs or bends running perpendicular to the recess edges or the swivel axis in order to achieve greater bending stiffness. This design is also suitable for the spacer element to increase the distance between the two components.

In the context of the present invention, in order to solve the problem described at the beginning, it is also proposed that the clamping jaw has a recess for receiving at least one edge of the bearing foot and is fixed to the bearing foot in the area of the recess, that the clamping jaw has a second fixing area spaced from the said recess and acting on the bearing foot, and that the clamping jaw carries a clamping device that interacts with the abutment and can thereby be fixed against the profile support. Here too, the clamping jaw pivots in the direction of the abutment, with the correspondingly dimensioned recess enabling this pivoting and the pivot axis lying in the area of the clamping jaw that encompasses the profile support and runs parallel to the profile support; however, the essential additional feature of this design is that the clamping jaw has a second fixing area, from which the bearing foot is acted upon at a distance from the first fixing area formed by the clamping jaw recess. This two-point support of the clamping jaw on the bearing base not only fixes it against any kind of displacement, but also prevents any tilting movement of the

This is particularly advantageous if the bearing foot is shorter than the profile beam width, meaning that the abutment cannot act on the bearing foot and cannot provide its second fixing position.

In this case, the clamping jaw is clamped against the abutment using the clamping device, with both the clamping jaw and the abutment gripping the profile beam. The two fixing areas of the clamping jaw, i.e. the area of the clamping jaw recess and the second fixing area, ensure that the bearing foot is fixed and press it against the profile beam.

To improve the fixation of the bearing foot, it is particularly advantageous if the bearing foot has a recess and the clamping jaw interacts with this bearing foot recess in the area of its recess and can thus be fixed to the bearing foot in a form-fitting manner. This and the second fixing area at a distance from it enable the bearing foot to be reliably fixed to the profile beam, which is independent of the profile beam width and thus meets the requirements for a bracket that can be used to support pipes on various profile beams.

The second fixing area of the clamping jaw is expediently positioned between the clamping jaw recess forming the first fixing area and the abutment on the bearing foot, whereby the second fixing area functions as a replacement for a fixing created by the abutment. This second fixing area is designed in such a way that it not only fixes the bearing foot itself, but also fixes it to the profile carrier, whereby the second fixing area is expediently formed by a clamping jaw recess and the recess is smaller in size than the height of the bearing foot edge acted upon by the clamping jaw in order to improve the fixing of the bearing foot. Here-

Λ λ

by a feed of the clamping device creates that this second fixing area is pressed over the edge of the recess against the bearing foot.

Advantageously, the clamping jaw is secured to the profile beam via a clamping groove that surrounds an edge of the profile beam, whereby the abutment also expediently has a clamping groove that surrounds an edge of the profile beam, and as a result the clamping jaw and the abutment are clamped against the profile beam via their clamping grooves.

In this case, the clamping device is preferably applied to the clamping jaw approximately in the area of the second fixing area, whereby the clamping device must have a length that depends on the profile beam width and bridges the distance between the abutment and the clamping jaw.

As far as the clamping jaw is concerned, this expediently consists of a sheet metal cut, which is in particular bent at least twice and thus has an approximately U-shaped configuration on one side of the bearing foot, with the two U-legs each acting on the bearing foot. However, the clamping jaw can also act on both edges of the bearing foot, for which purpose it is expediently constructed symmetrically and interacts with two abutments arranged on different sides of the bearing foot via two clamping devices running parallel to one another.

Figures 1 to 3 show a bracket 101 for supporting a pipeline (not shown) with a double-T-shaped profile support 103, a bearing foot 107 resting on its flange 104 and with two clamping jaws 114 and 118 respectively that fix the profile support and the bearing foot against each other, with the clamping jaw 118 acting as an abutment. As can be seen from Figure 2, both clamping jaws 114 and 118 are identically constructed and are connected to each other via two clamping screws 116.

To accommodate the bearing foot 107, the clamping jaw 114 - just like the clamping jaw 118 forming the abutment - has a slot-shaped recess 115, which is delimited on the upper side by a free end of the clamping jaw, namely a molded-on tab 112 that accommodates the clamping screws 116, and on the lower side by a spacer element 113 molded onto the clamping jaw. This spacer element 113 is arranged between the bearing foot 107 and the profile carrier 103 and increases the distance between the clamping screw and the point of application of the clamping jaw on the profile carrier, which leads to an increase in the clamping force due to the leverage.

As the clamping jaw is adapted to the width of the T-shaped bearing foot 107, it grips around one edge of this bearing foot flange on three sides with a recess, while it rests on the other edge on only two sides. At the same time, each clamping jaw 114 or 18 has two angle profiles 120, 121 running diagonally in the direction of the profile support on its underside to form a clamping groove with which it is secured to the profile support. In the assembled position of the clamping jaw shown in Figures 1 to 3, the recess edges are already clamped to the bearing foot, while in the loose state of the clamping jaw, there must be some play - albeit only a small one - between the recesses and the bearing foot, so that the clamping jaw is not hindered from being attached before it is pivoted and secured to the bearing foot.

From Figure 3, as well as from Figure 6, it can be seen that one hole for receiving a clamping screw 116 is provided in a free clamping jaw end 112a in the edge area of the profile support foot, while the other hole for receiving another clamping screw 116 is arranged in the molded-on tab 112 and is positioned offset in the direction of the abutment 118 approximately in the middle of the profile support width. The interaction with the identically constructed abutment 118 results in an even distribution of the clamping and bracing force on the profile support and bearing foot. Finally, in Figure 3 it can be seen that the clamping screw 116 fixes the abutment against the clamping jaw 114 with the help of a clamping nut 117.

In Figure 7, another bracket 1 for supporting a pipeline 2 is shown in perspective. The bracket 1 consists of a profile beam 3 in the form of a double T-beam, on whose flange 4 with flange surface 5 and flange edge 6 a bearing foot 7 in the form of a T-shaped slide is clamped. This bearing foot 7 has two pipe clamps 9 and 10 at the free end of its central web 8, which hold the pipeline 2 and fix it to the bracket. At its other end, the central web is

8 is connected to a flange 11 of the bearing foot, the flange underside 12 of which rests flat on the flange surface 5 of the profile support 3 with the interposition of a plate-shaped spacer element 13, which on the one hand serves to compensate for the height of the pipeline relative to the profile support 3 and on the other hand to increase the distance between the two flanges.

The size of the distance plays an important role in the inventive method of fixing the bearing foot 7 on the profile support 3, since this leads to an increase in the clamping force due to the lever ratio which is positively influenced thereby.

The bearing foot is secured to the profile support in detail by a clamping jaw 14, which is placed on the flange 11 via a recess 15 and has a clamping screw 16 on its underside, which acts on an intermediate bracket 17 arranged between the clamping jaw and the profile support 3 and serves to brace and secure the profile support and bearing foot against an abutment 18 arranged on the other side of the flange 4.

This interaction is shown more clearly in Figure 8: There, the clamping jaw, intermediate bracket and abutment are constructed almost identically; all three clamping elements have a recess with the help of which they are attached to the flange 11 of the bearing foot while leaving some play. All three elements are also angled in order to encompass the flange 4 of the profile carrier from the underside, i.e. from the side facing away from the bearing foot 7, in the sense of vertical and horizontal fixing. The abutment 18 and the intermediate bracket 16 each form a clamping groove by both gripping the flange edge 6. The clamping screw 16, which is also located on an angled section of the clamping jaw 14 and is thus in Fig.

gur is arranged oriented diagonally upwards, acts on the intermediate bracket 16 below the flange edge 6.

When clamping and securing, proceed as follows: The abutment 18 is placed on the flange 11 of the bearing foot 7 and brought into contact with the flange 4 of the profile support 3. Then first the intermediate bracket 16 and then the clamping jaw 14 are pushed from the opposite side onto the flange 11 of the bearing foot 7, whereby the intermediate bracket 16 is brought into contact with the flange 4 of the profile support 3 and the clamping screw 16 of the clamping jaw 14 is brought into contact with the intermediate bracket 16. When subsequently clamping the individual parts, it must be ensured that the clamping jaw 14 and the abutment 18 with their angled section are pivoted away from the profile support 3, overcoming the play of the recess relative to the flange 11, until the recesses on the flange 11 become jammed. The intermediate bracket 16, however, must be tilted in the opposite direction, i.e. towards the profile support 3. The frictional engagement of the respective recesses on the flange 11 that is established in this way is sufficient to enable mutual fastening when the clamping screw 16 is subsequently actuated. The clamping screw 16 presses against the angled section of the intermediate bracket 17, which initially bends it towards the flange 11.

After the bending limit of the intermediate bracket 14 is reached, it forms a fixed stop against the clamping screw, which now pivots the clamping jaw 14 away from the profile support 3. A further adjustment of the clamping screw 16 leads to the clamping jaw 14 being stretched outwards to its bending limit and, on the other hand, to the pivoting of the intermediate bracket 17 in the direction of the profile support 3 displacing the bearing foot 7 relative to the profile support 3 in the direction of the clamping jaw 16 until the abutment 18 is also stretched to its bending limit. In order to prevent the displacement of the

In order to ensure that the bearing foot 7 offers as little resistance as possible to the profile support 3, the pipe 2 should only be placed on the pipe clamps 9 and 10 after the bracket has been installed. Otherwise, the weight of the pipe would prevent the bearing foot 7 from moving, which would only clamp the clamping jaw and the intermediate bracket to the profile support while simultaneously fixing the edge of the bearing foot adjacent to it. Due to the lack of transmission of the feed movement, the clamping on the side of the abutment 18 could only be achieved by providing another clamping jaw with its own clamping screw on this side too, instead of the abutment 18.

Figure 9 shows a simplified version of the bracket compared to the embodiment of Figure 7, since the intermediate bracket is omitted here: The bracket 21 shown here connects a bearing foot 27, shown only in part, with a profile support 23 extending perpendicularly thereto. Both components correspond in their structure to the components in Figure 7 and have a spacer element 33 between them. On one side of the profile support 23 there is a clamping jaw 34 angled twice with two recesses 35 and 36 (the recess 36 can be seen in Figure 10), in which the bearing foot 27 is accommodated. The clamping jaw 34 has a clamping screw 37 on its one free end, which runs approximately horizontally and faces away from the profile support 23. When clamped, this screw pivots the clamping jaw in the direction of the profile support 23 until the clamping jaw comes into contact with the profile support 23 or its flange 24 with its other free end 38. Starting from the first free end, the clamping jaw - as seen in Figure 9 - runs at an angle obliquely upwards towards the bearing foot 27, gripping the bearing foot by means of the recess 35 provided in this section. After bending further downwards, it runs out in the free end 38, with the recess 36 being arranged in this section.

I · 9 9

As can be seen from Figures 10 and 11, the clamping jaw 34 is not tilted over its recess edges on the bearing foot when the clamping screw 37 is advanced; rather, only the two edges of the recesses 35 and 36 located on the top of the bearing foot 27 are pressed against the associated flange - as indicated by the arrows in Figure 11 - which means that the advance movement of the clamping screw 37 (the contact with the bearing foot 27 is also indicated by an arrow) is transferred to the free end 38 of the clamping jaw, with the edges acting as counter bearings.

The arrow shown in Figure 11 at the contact point of the free end 38 on the flange 24 of the profile support 23 illustrates the effect of the clamping force: similar to the intermediate bracket 17 from Figure 7, the free end 38 is arranged at an angle to the flange 24 and ensures that the profile support is clamped to the bearing foot in the vertical and horizontal direction. In the case of the embodiment of Figures 9 to 11, the spacer element 33 also has the task of changing the distance between the pipeline and the profile support and of improving the lever ratio of the clamping jaw up to the contact point on the profile support in order to increase the clamping force.

Figures 12 to 14 show a further embodiment of a holder according to the invention. Figure 12 shows only a clamping jaw 44, which is placed on a bearing foot 47 via its recess 45. The clamping jaw 44 also has a clamping screw 42 on its one free end facing away from the profile support (not shown), while it has the recess 45 on its other free end. The section lying between the two free ends, which has an approximately U-shaped course, is located with its leg having the recess in contact with a profile support 43. The clamping jaw 44 extends essentially on the underside of the bearing foot 47, whereby an actuation of the clamping screw in the sense of a

&bull; · &diams; · #*· &bgr;&psgr;&psgr;

Jamming leads to a bending of the free end of the clamping jaw 44 that receives the screw, which in turn causes the two edges of the recess 45 to become jammed against the bearing foot 47, whereupon a further adjustment presses the clamping jaw against the profile carrier 43.

The respective contact points are indicated in Figures 13 and 14 with the help of arrows. Here it is clear - as already indicated in Figure 11 - that the clamping jaw 44 transfers the clamping force obliquely to the profile support 43 and thus braces the bearing foot 47 against the stationary profile support 43 in the direction opposite to the arrow running obliquely to it. The embodiment in Figure 14 differs from that in Figure 13 in that instead of a separate spacer element 48, a clamping jaw tongue 49 is now provided, which fulfills the function of the spacer element. This clamping jaw tongue 49 is part of the free end of the clamping jaw 44, which has the recess 45, which must be recessed at this free end anyway in order to provide space for the central web of the bearing foot 47, which is not shown in Figures 12 to 14. However, this clamping jaw tongue 49 must be designed to be so flexible that it does not offer its own resistance bending moment to the feed movement by the clamping screw 42.

As indicated by the variant of the clamping jaw tongue, in the other embodiments described above the spacer element can only extend over a part of the overlap area between the bearing foot and the profile carrier, in particular over the edge areas assigned to the clamping jaw or the abutment.

As shown in Figure 15, the spacer elements can also fulfill other functions, namely they can be used to grip the profile beam on its underside, which makes the clamping jaw and abutment elements even simpler. The bracket in Figure 15 consists of a profile beam 53, on the flange of which

Two spacer clamps 58 and 59 are arranged on the top of the flange, which grip under both flange edges with the help of a hook-shaped, diagonally running extension. In addition, a bearing foot 57 extends through the two spacer clamps 58 and 59, onto which an abutment 56 and a clamping jaw 54 are attached in the manner described above.

The spacer clamp 58 is shown in a side view in Figure 16. There it can be seen that it has two upwardly extending bends 60, each of which encloses an edge of the bearing foot 57, to fix the position relative to the bearing foot 57. These bends are used in particular during assembly so that the spacer clamps can be placed together with the bearing foot on the profile support 53.

When installing the bracket shown in Figure 15, first the two spacer clamps 58 and 59 are pushed against the profile support 53, whereby the hook-shaped extensions of the clamps grip around it from below to form a clamping groove. The abutment 56 is then placed on the bearing foot 57 and wedged by pivoting the section extending below the bearing foot away from the profile support 53 to form a frictional connection with the bearing foot. Then the clamping jaw 54 is placed on the bearing foot in the same way from the opposite side of the bearing foot 57, its recess is wedged on it and clamped to the spacer clamp 59, the profile support 53, the spacer clamp 58, the abutment 56 and the bearing foot 57 by operating a clamping screw 52 arranged on the lower free end of the clamping jaw.

The structure of the clamping jaw 54 is evident from the side view in Figure 17: There it can be seen that the clamping jaw 54, which in the embodiments of Figures 7 to 14 was designed as a sheet metal blank, here consists of an arcuate cast part and has a recess 55 for each bearing foot edge to accommodate the bearing foot 57.

The arch extends from these recesses arranged at both ends and has a bore 61 in the middle between both ends for receiving the clamping device (not shown) 52.

Instead of the cast part, in the embodiment of Figure 15, the spacer clamp 59 can also be acted upon by a simpler design of a clamping jaw, since in this case the spacer clamp 59 forms the area of the clamping jaw that grips the profile carrier at its edge. Consequently, it is sufficient for a clamping screw 62 to be arranged at a height of the clamping jaw 64 that is not below the profile carrier 53. In this case, the clamping screw 62 only has to transfer the clamping force to the hook-shaped extension of the spacer clamp 59, which, due to the clamping groove it forms, transfers this clamping force further to the profile carrier 53.

Figure 19 shows such a simplified design of a clamping jaw 64, wherein a recess 65 for receiving the bearing foot 57 and a bore 66 for receiving the clamping screw 62 can be seen.

Figure 20 shows another design of a holder 70 with a clamping jaw 71, by means of which a bearing foot 72 is secured to a profile support 73 - shown in dash-dotted lines in Figure 14. The clamping jaw 71 has, as can also be seen from the top view in Figure 21, a recess 74 with which it grips the edge of the bearing foot 72. To increase its flexural rigidity, the clamping jaw 71 is profiled.

A tab 75 extends obliquely from the lower edge of the recess away from the clamping jaw or recess plane, whereby the tab 75 is connected in one piece to the clamping jaw 71 via the lower edge of the recess. A clamping device 76 is arranged at the free end of the tab 75, which acts on the bearing foot 72.

Finally, a spacer element 77 is placed on the tab 75, which has an opening adapted to the cross-section of the tab. This spacer element, which consists of a thin-walled sheet metal cut, extends from this opening through the recess of the clamping jaw and merges into a profiled section through which the bearing foot 72 is spaced from the profile carrier 73. This profiling allows the distance between the two components to be chosen to be larger than the material thickness of the spacer element 77 would allow.

Figure 22 shows a modification of the clamping jaw 71 from Figures 20 and 21: A clamping jaw 81 is shown there which is provided with ribs 82 which run perpendicular to the horizontally extending recess edges. These ribs can be used to increase the flexural rigidity of the clamping jaw or to reduce the material thickness while maintaining the same flexural rigidity.

A simple design of a clamping jaw 91 with a tab 92 running at an angle to it is shown in Figure 23. This clamping jaw has neither bends nor ribs, but its flexural rigidity is increased by the fact that its material thickness is correspondingly thicker.

Finally, Figure 24 shows this clamping jaw 91 with the spacer element 93 attached to the tab 92, which, similar to the spacer element 77 from Figure 20, is positively connected to the clamping jaw 91 via an opening 94.

Figure 25 shows an alternative design of a bracket 201 for supporting pipelines on a profile support 202, wherein the bracket consists of a bearing base that at least indirectly supports the pipeline

203 and a clamping jaw 204 that secures the bearing foot and profile support against each other. While the bearing foot and profile support correspond to the embodiments from the above drawings, the clamping jaw 204 is constructed differently compared to the previously described embodiments. For example, in the side view of the clamping jaw 204 shown in Figure 26, in which the hidden edges are not shown for clarity, it is noticeable that in addition to a recess 205 that corresponds approximately to the width and height of the bearing foot and enables the clamping jaw to be placed on the bearing foot, a further recess 206 is provided that adjoins the recess 205 and, together with the first recess 205, forms a step-shaped engagement area 207 that serves to secure the bearing foot 202. Here, the engagement area 207 engages in a corresponding recess 208 provided in the bearing foot, which can be seen in plan view in Figure 27. This results in a positive fixing of the clamping jaw relative to the bearing foot, whereby neither a horizontal displacement of the bearing foot nor its lifting off from the profile carrier is possible if the clamping jaw is displaced over the recess 205 after being placed on the bearing foot in such a way that the engagement area 207 comes to lie in the recess 208 of the bearing foot.

Figures 27 and 28 show a further special feature of the present embodiment, namely the second fixing area 209, which is spaced from the engagement area 207 and also acts on the bearing foot 203 and which, when the clamping jaw is tightened,

204 with the profile carrier 202 comes into frictional contact with the bearing foot 203. This prevents the bearing foot from pivoting even in the direction not blocked by the engagement area 207.

As far as clamping the clamping jaw against the profile beam is concerned, this is done on both sides of the bearing foot via an abutment

210, 211 and via clamping devices in the form of screw/nut connections 212, 213 connecting the abutments to the clamping jaw. In addition, the abutments 210, 211 and the clamping jaw 204 each have a clamping groove 214, 215, via which they each grip the flange of the profile carrier 202, whereby the lower contact point of the clamping jaw on the flange of the profile carrier acts as a pivot point when clamping the clamping jaw in the direction of the abutment.

The clamping jaw is - as can be seen from Figure 27 - constructed symmetrically, which is why every construction detail is assigned a mirror-image equivalent on the other side of the bearing foot.

In summary, the advantage of the present invention is that a holder for supporting a pipeline is provided which ensures a reliable fixing of a bearing foot to a profile support, regardless of the profile support width.
