Description

profile clip

The invention relates to a profile clamp for connecting components, such as tubes with flange-like end, with a

Clamp body of at least two segments which are formed part-ring-shaped and with at least one clamping means.

From the prior art profile clamps for connecting two pipes on the end flanges are known. The stability of the compound, especially under mechanical action, is of great importance.

Generic profile clamps have a number of in

Circumferential direction successive segments, which are mounted externally on the end flanges. The segments are approximately trapezoidal in cross-section with a central web and two legs formed inclined. The opening and thus also the inclined legs of the

Cross-section trapezoidal segments have radially inward, while the central web engages over the flanges of the tubes.

In the following direction statements refer to the

Symmetry axis of the profile clamp, which corresponds to the axis of symmetry of the tubes. An axial direction thus points in the direction of the axis of symmetry of the rotationally symmetrical tubes and extends parallel to the flow direction of a fluid guided in the tube. A radial direction is perpendicular to the axial direction and thus extends at the same axial height. A circumferential direction is perpendicular to the axial and radial directions; For example, it runs along the Lateral surface of the web of the segments or the lines at the same axial and radial height.

In the circumferential direction, the segments are part-circular, so that at least two segments for complete assembly of a generic profile clamp are necessary. Due to the sectional trapezoidal configuration of the segments, the legs prevent the end flanges of the pipe ends at a mutual removal in the axial direction. In support of this

Effect is usually on the bridge of the segments

circulating belt provided. In a stretched state

the band acts on the segments with a radially inward force.

The disadvantage of the generic profile clamps is that the flanges or the legs of the segments can absorb only a limited tensile force acting on the tubes, so that the risk that the legs are bent when exceeding a force acting on them or a bending moment and the connection Both pipes can be solved thereby, with the result of possibly serious damage to the environment.

It is therefore the object of the invention to develop a profile clamp which, while avoiding the above disadvantages, has an improved load-bearing capacity, in particular under high mechanical stress.

The object underlying the invention is achieved by a profile clamp of the type mentioned above, which is characterized in that the segments have a central web, on both sides of the same in each case a radially inwardly directed legs each having an axially pointing away from the web-shaped integrally formed groove-shaped end portion and that the traction means at least partially in the

einliegen groove-shaped end portions of the segments.

In particular, the traction means over the vast majority of their length or their circumference on the end portions of the segments, preferably over more than 90% of the circumference or more than 330 °. Between two adjacent segments there is a space in each case in the circumferential direction. Its length in the circumferential direction is very small compared to the

Extension length of the segments.

Preferably, the diameter of a ring contour determined by the groove-shaped end sections is smaller than the diameter of a through the middle webs

Segments specific ring contour.

The legs of the segments preferably in

Radial direction same height, but also can

have different height, for example, in particular, if pipes / pipe sections with different

Outer diameter to be connected to each other.

Due to the design of circumferential, axially formed

End portions of the segments can serve as an abutment to accommodate radially inwardly directed forces of the traction means. However, the latter also serve to absorb forces acting on the tubes or bending moments on the legs of the segments. Thus, the inventive Clamp on a higher load capacity. This causes a secure connection of the two pipe elements.

The end portions may be formed as outwardly directed grooves; They thus have a concave contour radially outward. As a result, the traction means are held securely on the end portions of the segments. Here are the

End portions preferably in cross-section part-circular, in particular semicircular. Alternatively, the end portions may be polygonal in cross-section,

be formed in particular rectangular, with the - concave - pointing groove in the radial direction to the outside. The segments themselves may be forgings, castings, turned parts, embossed parts and / or deep-drawn parts.

Most preferably, the tensioning means may comprise at least two traction means each lying on an end section of the segments or in a groove. By the traction means said radially inwardly directed force is applied in a particularly effective manner to the segment. Traction means represent a particularly simple implementation to build a circumferential and closed ring tension.

Alternatively, a single traction means may be in the form of an endless rope or belt. This spans all

End sections / grooves of the segments. The use of a

single traction device for the clamping device goes with a

Reduction in effort associated. It eliminates the otherwise

possibly required use of several, shorter traction means and a connection thereof with each other. In both cases, the traction means, for example, via loops and crossing and / or wrap around

Arrangements be mounted in the individual grooves. Thus, several sections of the same traction means or several different traction means on each one end portion

rest. Due to the clamping action of the traction means, the radially inward force is produced on the end sections of the segments. By an enclosing and / or crossing arrangement of the traction means, the force on the segments and the load capacity of the compound can be increased overall, without this being associated with a large, constructive overhead.

The tensioning means may be components - traction means and / or

Turnbuckle - made of metal, preferably as wire,

in particular solid, or rope, made of suitable plastic and / or composite materials. In this case, the tensioning means, in particular components with aramid fibers

exhibit .

It may be advantageous for at least one

Connecting element, preferably in the form of a clip, between the at least one segment and the at least one

Traction means is provided. By the use of

Connecting elements between one or more traction means and one or more segments in particular the maintenance of both elements is improved with each other. The

Connecting element also serves as Verlierschutz for the traction means and as an assembly aid for the profile clamp.

The tensioning means has at least one turnbuckle above the at least one pulling means, by way of a user the tension on the at least one traction means and thus the clamping means can be applied or released on. This is preferably designed as a closing and / or screwing device. The turnbuckle acts on the segments via the at least one traction means with a tensile force in

Circumferential direction. This creates a radially inward force which, as shown, engages the end portions of the segments.

The turnbuckle can in particular radially outward

be arranged at least one of the segments and is preferably located on a web of the segments. This area is generally easily accessible and allows easy and quick installation. The turnbuckle causes the already described clamping effect of the traction means in a particularly simple manner.

The turnbuckle is preferably designed as a screw device. This acts on the at least one traction means with a tensile force. This type of embodiment of the

Turnbuckle represents a particularly simple way to achieve the desired clamping effect of the traction means.

Here, for example, the ends of the traction means can be acted upon by the use of one or more screws with a force that leads to the desired clamping effect. Furthermore, this type of embodiment has a high degree of mechanical strength.

The turnbuckle can continue to prevent rotation

have, in particular form-fitting manner, for example in the form of a groove with a square. Also, the head of at least one screw can be configured as a polygon, in particular as a square to a

To hold against when tightening the nut of the turnbuckle.

As an alternative to the screwing device, the turnbuckle can also be designed as a worm gear, wherein the

Worm gear in particular has a worm shaft. This constitutes an alternative embodiment of the

Turnbuckle through the use of a

Worm gear can be the exciting effect on the

Traction means are particularly accurately dimensioned. Also, a worm gear is a particularly simple form of a turnbuckle.

However, the turnbuckle may preferably also have a lever joint, in particular with two lever parts. These

allow a particularly simple exercise and solution of the tensioning effect on the traction means. Such a lever joint also offers the advantage of manual operation without further aids or tools.

It may prove advantageous in the embodiment of the turnbuckle, for each individual traction means

provide separate turnbuckle. Thus, for example, the mechanical tension can be matched to the respective individual traction means. Alternatively, it may be advantageous to have a common turnbuckle for at least one group of

To provide traction means. In particular, by a common housing, this is associated with a saving of material and effort. Preferably, at least one further clamping element can be provided, which is arranged on the radial outer side of the at least two segments, that rotates on the webs of the segments. The further tensioning element is preferably a circumferential belt in the circumferential direction of the profile clamp,

in particular flat band. Such a further clamping element increases the load capacity of the connection of the two tubes in addition, since there is an additional, radially inward

directed force on the segments causes and due to its design and the design of the flanges of the tubes exerts an axial contact force on the latter. The further clamping element engages in particular on the central webs of the segments and contributes to an increase in the

mechanical stability of the compound.

By one or more embodiments of the

Clamp according to the invention can be compared with the bending moment occurring on the segment by about 20% to 50%

Preferably, the at least one segment

Offer benefits. In particular, if required by the structural conditions of the subsequent pipeline, an asymmetrical design of the segments can provide additional space. Further advantages and features of the invention will become apparent from the claims and the following description in which

Fig. 1 shows a profile clamp 1 in accordance with the invention

perspective view. It has a circular shape. The profile clamp 1 has a clamp body 4 and a clamping means 5. The profile clamp 1 separates an inner space 2 surrounded by it from an outer space 3 located outside.

In the following, an axial direction denotes a direction parallel to the indicated symmetry axis A. A radial direction is perpendicular thereto. The circumferential direction is

characterized by a same axial position in

Projection to the axis A and a constant radial distance to the axis A.

The clamp body 4 consists of four quarter-circular segments 6. The length of the segments 6 is in the circumferential direction big compared to their axial strength. Between each two adjacent segments 6 is a gap. 7

The segments 6 have a central web 8, to the two ends 15 in the axial direction in each case a leg 9 connects. The two legs 9 each extend in the axial direction away from the web 8, they also have an additional radially inwardly directed

Extension component on. At the axially outer ends 20 of the legs 9, in each case an end portion 10 connects. The end portions 10 are bent axially outwardly, away from the central web 8, in a semicircular shape, being concave in section radially outwardly. The end portions 10 each form a circumferentially extending groove 11 which faces outward in the radial direction.

The clamping means 5 of the profile clamp 1 of FIGS. 1 and 2 has two traction means 12 and a turnbuckle 13.

The two traction means 12 are in the embodiment as

Metal wires designed. They can be solid or consist of single wires. You can also choose from others

Be made of materials such as suitable plastic. In particular, they may also have aramid fibers. The traction means 12 have at their respective ends end portions 14. The traction means 12 extend in the circumferential direction of

Clamp 1. Both traction means 12 are arranged in the grooves 11 of the end portions 10 adjacent to the central web 8 of the segments 6. Their radial height is less than that of the

Leg 9 of the segments 6; the traction means 12 thus have a smaller distance from the axis A than the webs 8. The lengths of the two traction means 12 are equal to 10 and correspond The strength of the traction means 12 corresponds to the dimensions of the grooves 11th

The end parts 14 of the traction means 12 face each other and are connected to the turnbuckle 13. This sits on the outside of the web 8 of a segment 6. For this purpose, the traction means 12 extend in the region of the turnbuckle 13 on this. Their radial height increases in this area, the traction means 12 thus leave there the grooves 11. In this area, the traction means 12, however, still have the same axial height, the traction means are thus seen radially above the grooves 11th

Fig. 2 shows in this regard an enlarged view of the 25 profile clamp 1 in the region of the turnbuckle 13. Das

Turnbuckle 13 has two transverse anchors 15 and a screw 16 with an abutment (not shown).

Both transverse anchors 15 are mounted radially above a segment 6 and extend in the axial direction

same, radial height. They are designed in the present example as cylindrical bolts and can in particular be made of metal, such as steel. The transverse anchors 15 may also consist of suitable plastic, such as aramid. In Fig. 1, a transverse anchor 15 is connected to one end portion 14 of the two traction means 12 in each case. There are two each

End portions 14 at the same height in the circumferential direction. The

Connection itself can be done for example by welding, force or positive engagement. At half the axial height of the left transverse anchor 15 is provided with a threaded bore whereas the right transverse anchor has a through hole. The thread and the

Through holes extend perpendicular to the

Extension direction of the transverse anchor 15. In the threaded hole, the screw 16 can be screwed.

The screw 16 extends perpendicular to both transverse anchors 15. The thread of the left transverse anchor and the screw correspond to each other.

At its one, in Fig. 2 right-most end, the screw 16 has a screw head 17 whose diameter in the illustrated embodiment in cross section is twice as large as the diameter of the remaining screw 16. Der

Screw head 17 is preferably formed so that the screw 16 can be rotated by a tool, so for example by an external or internal polygon.

At the other, in the circumferential direction opposite, left end of the screw 16 may be provided an abutment (not shown). In this case, there is a through hole in both transverse anchors.

By turning the screw 16, both transverse anchors 15 move toward each other in the circumferential direction of the profile clamp 1.

In this case, a tensile force acts on the traction means. This leads to a radially inwardly directed force of the traction means 12, which is transmitted to the end portions 10 of the segments 6. The point of application of this inwardly directed force is radially seen within the central webs 8 of the

Segments 6.

Fig. 3 shows a representation of the cross section of

Clamp 1 according to the invention, with two pipes 18 to be connected, each having a pipe end 19, each having an end flange 20.

The profile clamp 1 is in Fig. 3 radially outside the

Pipe ends 19 attached. In this case, the central web 8 of the segment 6 shown is located radially outside the end flanges 20. The slopes of the legs 9 correspond to the respective pitch of the sloping flanks of the end flanges 20. Die

End portions 10 of the profile clamp 1 and thus the traction means 12 over the greater part of their length are radially directly on the tubes 18 and in particular radially closer to the

Symmetry axis A as the peripheral edges of the flanges. With regard to the other components, reference is made to the above statements. The turnbuckle 13 is not in Fig. 3

drawn.

Pipe ends 19 with the respective end flanges 20. Die

Clamp 1 overlaps with their segments 6, the two end flanges 20. The radial distance between the web 8 and the end flanges 20 is small compared to the extension in

Circumferential direction of the segment 6. Further, in Fig. 4, the two traction means 12 are shown, which in the end portions 10 of Segments 6 are introduced and are arranged in each case in the circumferential direction.

FIG. 5 shows an alternative embodiment of the invention

Turnbuckle 13: The embodiment is similar to the turnbuckle 13 in Fig. 2, it has in particular a screw 16 with a screw head 17. Also, the end portions 14 of the traction means 12 shown one can be seen and each connected to a transverse anchor 15. This embodiment comprises a crossing of the end parts 14 of the traction means 12 in the region of

Turnbuckle 13 up.

As already mentioned, both end parts 14 are each connected to a transverse anchor 15. However, only the transverse anchor 15 has a right near the screw head 17 arranged on the right

Threaded hole. This is arranged as already described at half the axial length of the transverse armature 15. The other, remote from the screw head 17 transverse anchor 15 has a blind hole. The screw head 17 opposite end of the screw 16 engages in the non-continuous threaded bore of the left transverse anchor 15 a form-fitting.

By pressing the screw 16, the two end portions 14 of the traction means 12 are pressed apart in the direction of removal. This causes a clamping force on the traction means 12, which has a radially inwardly directed force on the

End portions 10 of the segments 6 within the traction means 12 causes. In this regard, be aware of the above

References. Fig. 6 shows a further embodiment of a turnbuckle 13. Again, there is a crossing arrangement of the end portions 14 of the traction means 12 before. In the area of the end parts 14, a housing 31 is provided, in which the end parts 14 extend, partially crossing each other. The housing 31 engages over web 8 and leg 9 of the corresponding segment 6 of FIG

Clamp 1. The end portions 14 occur at opposite openings 29 of the housing 31 from these. They are provided in this embodiment with a thread (not shown). The thread is on the internal thread of

Tension nuts 30 tuned to find their abutment in the arrangement shown in Fig. 6 on the housing 31.

With the help of the clamping nuts 30, a clamping force can be exerted on the traction means 12 by the housing 31 as an abutment. This force acts, as already mentioned, in

Circumferential direction of the traction means 12 and leads to a radially inwardly acting force on the end portions 10 of

Segments 6.

FIG. 7 shows an embodiment of the one shown in FIG

Turnbuckle 13 with a housing 31 and clamping nuts 30 in a radial view. The common housing 31 for both traction means 12 has four openings 29 for the end portions 14 of the traction means 12. In contrast, in an alternative

Embodiment in Fig. 8 for each traction means 12, a separate housing 31, each provided with two openings 29. The rest of the structure corresponds to the already above

explained.

FIG. 9 shows a further embodiment of a

It has only a single, designed as an endless belt traction means 12 and an unspecified turnbuckle 13. The traction means 12 has at its two ends in each case a loop 25. The two loops 25 are connected to the turnbuckle 13 and therefore point towards each other. By pressing the turnbuckle 13, both loops 25 move toward each other in

umläufiger direction, so that the traction means 12 with a

umläufigen clamping force is applied. The turnbuckle 13 may, for example, have a threaded bolt 26 with a continuous longitudinal slot which ends at a distance from both ends of the threaded bolt 26. Through this slot, the loops 25 of the traction means 12 are guided. By screwing the nut 27, the loops 25 are moved towards each other and thus tensioned the clamping means 5 on at least one end of the screw 26.

FIG. 10 shows, in a schematic section, a further embodiment of the profile clamp 1 according to the invention

Structure is largely similar to the embodiment of FIGS. 1 to 4. Here, however, an additional clamping element 28, shown in the form of a circulating on the web 8 of the segments 6 band. By applying the tensioning element 28 with a tensile force, a radially inwardly directed force arises, which attaches to the web 8. In addition, one is

Turnbuckle 13 outlined. This acts on the traction means 12 with a clamping force, but in addition to the

Apply tensioning element 28 with a clamping force.

Fig. 11 shows an alternative embodiment of

Clamping device 13. Here, first, a traction means 12 with two end portions 14 and a segment 6 can be seen. The

Turnbuckle 21 is designed here as a lever joint, the one short lever part 22 and a long lever part 23 has. The lever parts 22, 23 have opposite end faces.

The length of the long lever part 23 is twice as long as the length of the short lever part 22.

One end of the long lever portion 23 is pivotally connected to the located in Fig. 11 on the right side end portion 14 of the traction means 12, for example by a rivet or screw. The other, free end 24 of the long lever member 23 protrudes - in the non-cocked position - substantially in the radial direction to the outside. The opposite, so arranged on the left side end portion 14 is connected in the same way with the short lever portion 22. The other end of the short lever part 22 projects in the radial direction outwards toward the long lever part 23. The other end of the short

Lever part 22 is at mid-height of the long lever member 23 with this, also via, for example, a rivet, articulated.

In the structure shown in Fig. 11, the lever joint 21 is shown in the open state. The traction means 12 lies in the end portions 10 of the segments 6, without transmitting a radial force inwardly to the segments. By operating the free end 24 of the long lever portion 23 from the short lever portion 22 away, in the representation thus clockwise, the turnbuckle 21 is closed.

This clamping state is shown in FIG. 12: The distance between the two end parts 14 of the traction means 12 is reduced by the movement of the long lever part 23. The short lever part 22 runs along the long lever part 23 and extends parallel to this. By clamping the two end portions 14 against each other again a force is exerted on the traction means 12. This force manifests itself as the elasticity of the

Clamp 1, as already described in the other embodiments.

In Fig. 13, a segment 6 of a known profile clamp according to the prior art in a schematic half-section is shown, so that here only half the web 8 and a

Leg 9 is shown. The segment 6 shown is

symmetrical to a running in the radial direction

Symmetry axis S designed. For the left part, not shown, the following statements apply accordingly, taking into account the symmetry. The generic segment 6 is exerted by a running on the web 8 of the profile clamp 1 strap, acting from a force acting on the web 8 radially inwardly facing holding force R.

applied. Occurs during operation, a separation force N on the ends of the strained tubes, this causes a substantially radially outward, and an axially facing force component in the direction of the axis A on the legs 9 of the segments 6th of the end flange 20 on the leg exerted force N generated in the symmetry section S, the axial

Reaction force H and a radial reaction force R im

Tie. The maximum bending moment Mmaxr, which essentially determines the dimensional stability of the segments 6, occurs in FIG

Symmetry cut S at the point Z and is calculated to Mmax = N-a-R-b. Here, a is the vertical distance of

Line of action of the force N to the symmetry point Z and b the vertical distance of the radial force R to the symmetry axis S. If the maximum torque Mmax reaches the load limit, the segment 6 bends about the pivot point Z and the connection fails. In contrast, in Fig. 14, the segment 6 of

inventive profile clamp 1 shown. Again, for symmetry reasons, only the right part of the segment 6 is shown. The inventive profile clamp 1 has by the clamping means 5 according to the invention a fixing force Rl, which engages radially inwardly at the end portions 10 of the profile clamp 1 according to the invention.

In FIG. 14, the separating force N, already mentioned in FIG. 13, is also shown at the distance a. However, by means of the direction and starting point of the fixing force R ', a larger counter-torque takes place here at the said bending moment Mmax, so that for the resulting torque Mmax' follows: M'max = N * a-R '* b'. b 'is the vertical distance between

Starting point of the holding force Rl at the end portion 10 and the middle of the web 8. The amounts of the radial forces R and Rl are identical for the same normal force N, so that the reduction of the bending moment Mmax 'by the approximately 3 times larger lever arm b' of the radial force R ' comes.

The inventive profile clamp 1 a occurring by processes in the pipe system bending moment is significantly reduced or compensated. In this case, the traction means 12 in the end portions 10 of the segments 6 cause a radially inwardly acting force.

The profile clamp 1 according to the invention is as follows

attached: First, the tubes 18 with the attached to the pipe ends 19 end flanges 20 with each other in

Brought in contact. At this junction are in

Circumferential around the outside of the end flanges 20 a Number of Segementen 6, preferably two to four segments 6, created. Thus, the clamp body 4 is attached.

In the next step, the clamping means 5 is attached. For this purpose, the traction means 12 together with turnbuckle 13 in

Circumferentially mounted in the grooves 11 of the segments 6. The traction means 12 are then in the grooves 11 of the end portions 10. The turnbuckle 13 is mounted radially outside of the segments 6. Thus, the clamping means 5 is attached.

Now the turnbuckle 13 is actuated, while the

Pulling means 12 acted upon by a force in the circumferential direction. This manifests itself in a radially inwardly directed force on the segments 6, which attaches to the end portions 10. The clamp body 4 from the segments 6 is thereby pressed onto the Verbindunsgstelle both tubes 18. The operation of the turnbuckle 13 is done such that the pipe ends 19 of the tubes 18 are firmly clamped by the inventive profile clamp 1 against each other and a sufficient

Closing action is given.

During operation, for example in the transport of hot fluids in the interior 2 of the tubes 18 can be large

Separation forces N arise that generate an additional bending moment in the symmetry section of the segments 6.

A sufficiently large release force N on a generic profile clamp 1, which in particular has no end sections 10 with traction means 12 guided therein, leads to a

Bend of the segments 6. This allows the segments 6 and thereby solve the profile clamp 1 of the connection of the tubes 18. This can cause great damage.

By using the profile clamp 1 according to the invention, the bending moment is reduced to the segments 6, in some cases considerably. Details on this can be found in the above explanations. This is a safe operation and an extension of the possibilities for the invention

Clamp 1 given.

To remove the profile clamp 1 is first the

Turnbuckle 13 solved. This reduces the fixing force R on the segments 6. Subsequently, the traction means 12 are released and removed. By a subsequent release of the segments 6 of the end flanges 20, the profile clamp 1 can be removed.
