Description

[0001] The invention relates to a clamp with a bracket for attaching tubular bodies to a suitable base according to the preamble of claim 1.

[0002] Such clamps or mounting clamps with bracket are used when a high mechanical force is required to fasten containers or pipes or tubular bodies to a suitable substrate (e.g. ceilings and walls) as well as in machine and plant construction.

[0003] To enclose these bodies, the clamps typically feature a metal clamp band. For radial clamping, clamping heads are provided at the circumferential ends of the clamp band, through which a corresponding clamping device is passed for radially tightening the clamp.

[0004] The brackets are usually U-shaped and often feature flat sections for attaching the bracket, which is connected to the clamp, to a suitable surface. Standard versions often have a so-called "open" bracket and are therefore only suitable for applications where relatively lightweight structures are being mounted and where relatively low mechanical loads occur. Open brackets have a curved central section with two flat sections on either side that run parallel to the surface.

[0005] The connection of the bracket, which is usually also metallic, to the clamp band of the clamp is generally done using older resistance welding processes, such as spot welding, and due to the principle and design, at least five weld points are applied. Furthermore, the clamp-bracket configurations are inherently composed of at least seven individual or half-parts.

[0006] Furthermore, when connecting the bracket to the clamp and / or when forming / shaping the clamp in the area of ​​the clamping heads, expensive drilled parts and heavy-duty screws with nuts (e.g. M12) are used, and external bores on the clamp-bracket configuration are additionally riveted in a further manufacturing step.

[0007] A major disadvantage of the existing clamps with brackets is the older spot welding method, which is still in use. If significant vibrations occur during application after the clamp is attached, the described weld is not sufficiently secure and does not provide adequate strength for the entire application. The spot-welded parts can develop cracks, causing the bracket attached to the clamp band or clamp to lose its grip. These welding processes also negatively impact energy efficiency because they require a significant amount of electrical energy. Spot welding typically involves applying pressure and heat to the weld area using current-carrying electrodes. Furthermore, increased corrosion can form, particularly at the weld points, after the spot welding process.

[0008] Furthermore, this manufacturing process is more complex, requiring features such as riveting the outer holes and using heavy-duty screws, which necessitates specific shaping. At the same time, this manufacturing and welding process inherently limits the use of certain material groups, restricting the material selection.

[0009] The aim of the invention is to overcome these and other disadvantages of the prior art and to provide a clamp with a bracket that can be manufactured more cost-effectively and easily.

[0010] The main features of the invention are specified in the characterizing part of claim 1. Embodiments are the subject of further claims 2 to 16.

[0011] In a clamp, in particular for fastening tubular bodies to a suitable base, comprising a clamp band with a first and a second clamping head, in each of which a through-opening is formed through which a clamping element for tensioning the clamp is guided, and a bracket for fixing the clamp to a suitable base, it is provided according to the invention that the clamp band has at least two connecting structures for partially receiving the bracket, wherein the bracket can be fixed to the clamp by interaction with the connecting structures of the clamp band.

[0012] Due to the inventive, direct fixation of the console to the clamp via the connection structures of the clamp band, no material-bonded connection is created and the disadvantages described above, associated with spot welding, are effectively avoided.

[0013] The solution according to the invention ensures that, when connecting the bracket to the clamp band, it can be partially inserted or received into the designated connection structures, preferably via two leg ends, and thus fixed with the clamp, without altering the material structure through spot welding and producing the aforementioned associated adverse effects. A significantly improved mechanical strength of the entire connection is achieved without the risk of corrosion at local weld points.

[0014] This also reduces manufacturing costs and time, resulting in simpler production of the clamp with bracket. The inclusion of at least two connection structures supports and ensures mechanical balance during clamping and a largely symmetrical force distribution.

[0015] A suitable mounting surface can be, for example, a ceiling or a wall to which the bracket, fixed to the clamp, can be attached. Preferably, the bracket according to the invention is designed such that a wide variety of clamp types can be fitted with it. This increases compatibility and expands the scope of application of the invention.

[0016] In a preferred embodiment, the bracket can be fixed to the at least two connecting structures of the clamp band by means of a positive and / or non-positive connection. The positive and / or non-positive connection provides a secure mechanical fastening with sufficiently good strength values, particularly when both connection types are used together, for example, in the form of a snap-fit ​​or click mechanism. At the same time, such a fixing proves to be particularly simple and cost-effective to implement. Furthermore, the fact that no welds are created reduces the notch effect.

[0017] Furthermore, this opens up the possibility in the design of selecting a combination of different materials that cannot be welded together in principle, such as plastic and steel or a light metal, for the clamp band and the bracket, because a material-bonded connection by means of a spot welding process is no longer necessary.

[0018] This eliminates the need for riveting external holes during fastening, as well as the requirement for expensive drilled parts and generally oversized heavy-duty screws. This further optimizes and reduces the cost of manufacturing the clamp. Instead, a cap screw with a nut, preferably a hex bolt with a nut and an M10 thread, can be used. This further contributes to a lightweight and compact design of the clamp and bracket.

[0019] Furthermore, this offers the additional advantage that, compared to older solutions which inherently comprise at least seven parts, the number of parts can be reduced to five because spot welding or riveting of external holes is no longer necessary. Consequently, external electroplating is no longer required to prevent corrosion. Simpler coating methods, such as cost-effective pre-galvanizing, can be used to protect against corrosion and other chemical stresses, further optimizing the manufacturing costs and effort of the clamp and bracket.

[0020] To absorb and more effectively dampen shocks and vibrations, and to protect the material of the clamp band and the bracket, the clamp band can preferably be equipped with a rubber profile that completely encases the clamp band on its inner side. At the same time, the rubber profile advantageously provides protection against penetrating water and simultaneously seals the pipe or tubular body being clamped against the clamp or clamp band.

[0021] According to a further preferred embodiment, the connecting structures of the clamp band can each be formed by at least one tab, a locking element, and a recess, wherein the at least two connecting structures can be formed diametrically opposite each other on the circumference of the clamp band. This further supports a symmetrical design and a symmetrical force application and distribution, which has a positive effect on the mechanical strength of the connection between the bracket and the clamp band.

[0022] Preferably, two tabs can be provided which, in the axial direction of the clamp, wrap around the partially received section, preferably a leg end, and enclose it at least partially. Preferably, the at least two tabs face each other and extend in the axial direction of the clamp band. This further supports a positive and non-positive connection and ensures a secure hold between the bracket and the connecting structure. Preferably, the at least two tabs extend radially along the clamp only to the extent that the insertable part of the bracket is inserted under an interference fit, and the two tabs are partially deformed radially outwards. This allows a sufficiently large clamping force to be generated in the radial direction of the clamp band to ensure secure fixation of the bracket to the clamp band.

[0023] Preferably, at least one locking element of the connection structure can be designed to complement a recess in the partially insertable part of the bracket and interact in such a way as to further promote a force-fit and form-fit connection. Overall, this measure also increases the reliability of the connection and its mechanical strength. In this way, local component failure and the formation of cracks are further counteracted.

[0024] Preferably, when connecting the console to the clamp band, corresponding complementary elements of the console can engage in the respective recesses of the clamp band's connecting structures. These elements can preferably be specially designed locking lugs, preferably formed at the ends of the console legs. This ensures a secure and firm locking connection when the console is attached to the clamp band. Advantageously, this offers the option of implementing a click or snap mechanism, or a clamping mechanism, for securing the connection.

[0025] Preferably, the bracket can be arranged and aligned essentially diametrically opposite the clamping heads of the clamp. Furthermore, preferably, the at least two connecting structures can be arranged essentially centrally around the circumference of the clamp band, that is, approximately at 180° to both sides of the clamp band, between the clamping heads and the diametrically opposite bracket. This design also promotes a symmetrical structure and symmetrical force application and distribution when tightening the clamp via the clamping heads and / or when fixing the bracket connected to the clamp to the suitable base. At the same time, the symmetry facilitates simpler manufacturing of the clamp.

[0026] According to a further preferred embodiment, the console can have a base body facing the suitable support with a central curved section and with two flat sections adjacent to the curved section, wherein openings can be provided on the flat sections, through which the clamp can be fixed to the console on the suitable support.

[0027] Preferably, the flat sections and the base body can be arranged parallel to the suitable support, which, in turn, can also be substantially flat. This creates sufficient clamping force between the flat sections and the support when the bracket is fixed, preferably using fixing elements that pass through the openings of the flat sections and engage with the support. Furthermore, this allows the bracket to be placed on the support via the flat sections and pre-adjusted more easily. Overall, this measure also increases the strength and safety of the entire connection.

[0028] Preferably, the bracket can also be designed as a closed bracket. This means that, unlike the "open" design mentioned earlier, the bracket can be bent towards the lateral connecting structures after its flat sections in order to partially engage the clamp band. This creates a "closed" design towards the sides of the bracket because the bracket legs adjacent to the flat sections form the outermost edges of the bracket and "close" the bracket laterally due to the bent design. This measure is therefore advantageously suited for applications where relatively heavy structures are fastened and where relatively high mechanical loads occur. While the open brackets also have a curved central section, the two flat sections arranged on the sides do not extend towards the locking structures.Clamping heads with bent legs or the like, which is why the clamp-console configuration is "open" laterally in the open design of the console.

[0029] According to a further preferred embodiment, the invention provides that the curved section can be shaped to fit an outer surface of the clamp band, wherein the clamp band can have at least two projections which, when the clamp band is connected to the bracket, can engage in openings provided for this purpose in the bracket. For this purpose, the bracket can preferably include two openings corresponding to the projections of the clamp band. This ensures a secure fixation between the clamp band and the bracket. At the same time, this creates a pre-positioning option that supports a precisely centered or symmetrical arrangement of the bracket between the clamp band and the suitable base. As a result, the bracket is always correctly positioned in relation to the clamp or the clamp band and can consequently ensure improved mechanical strength and force distribution.

[0030] According to a further preferred embodiment, the curved section can, in the fixed state, bear in full contact with the clamp band, wherein the flat sections can be arranged with respect to a radial direction of the clamp such that, in the fixed state of the bracket, they are positioned closer to the suitable support than the curved section. This advantageously reduces the surface contact and the frictional forces between the suitable support and the bracket, because only the flat sections of the bracket contact the support, and a gap is created between the curved section of the bracket and the support, whereby the curved section does not touch the support.This also results in greater surface pressure between the bracket and the suitable base, because the contact area is concentrated solely on the relatively small surfaces of the flat sections of the bracket that are aligned parallel to the base. This, in turn, strengthens the fixation and further improves the mechanical strength of the connection. In addition, vibrations and oscillations can be better dampened by the space beneath the curved section of the bracket.

[0031] Preferably, the bracket can have a first and a second leg, each leg being provided with at least a first and a second leg end that are designed to be complementary to the connecting structures of the clamp band and can be inserted into them. This ensures secure fixation between the clamp band and the bracket via the legs and leg ends of the bracket. This method has proven to be particularly advantageous and effective because the design of leg ends corresponding to the connecting structures is simple and cost-effective to implement in manufacturing.

[0032] According to a further preferred embodiment, the legs and leg ends of the bracket can at least partially encircle the clamp band, with the legs of the bracket being bent over and projecting towards the connecting structures of the clamp band. Preferably, the legs and leg ends of the bracket can be arranged substantially perpendicular to the flat sections, and the bracket and its individual sections can be formed in one piece and from a single material. By partially encircling the clamp, the bracket can, for example, partially enclose or surround it, thus making the connection between the two components even more secure. The bent legs and leg ends can reliably interact with the locking structures formed laterally on the clamp band.

[0033] According to a further preferred embodiment of the invention, the legs and leg ends can be arranged essentially perpendicular to the flat sections of the bracket, the legs having an inclination of 2° to 7°, preferably 2° to 5°, towards a central longitudinal axis of the clamp. This ensures that a sufficiently large clamping force is transmitted radially along the legs to the clamp band, making the fixation even more secure. The inclination towards the clamp or central longitudinal axis of the clamp also facilitates pre-positioning of the bracket and the interlocking and interaction between the locking structures and the leg ends of the two bent legs.

[0034] According to a further preferred embodiment, the leg ends can be formed by locking ribs, wherein the locking ribs of the leg ends can each extend between a rounded edge projecting radially inwards towards the central longitudinal axis and a rounded edge projecting radially outwards. Due to the radially rounded edges of the leg ends, the locking ribs of the leg ends adapt to the corresponding recesses in the locking structures when fixed. The locking ribs are thus more easily inserted into the designated spaces, which further simplifies assembly between the bracket and the clamp band.

[0035] Preferably, the locking lugs of the leg ends can be inserted into the connecting structures of the clamp band during the interaction and connection of the bracket in such a way that the locking lugs are at least partially enclosed by the tabs and form a force-fit and / or form-fit connection. The tabs thus prevent the locking lugs from radially popping out of the lateral locking structures of the clamp band and therefore additionally secure the fixation.

[0036] In a further preferred embodiment, the leg ends can have at least one recess for receiving complementary elements of the connecting structures and at least one bearing surface for circumferential contact with the clamp band when the clamp is tightened. The complementary element, which can be inserted into the recesses of the leg ends, can preferably be formed by the locking element(s) of the lateral connecting structures of the clamp band. This allows a secure positive-locking and / or force-locking connection to be established. The locking element can have a lug that widens in the axial direction of the clamp and can engage in a suitable undercut of the recess for positive locking. Preferably, the locking element can be designed to be complementary to the recess in the connecting structures.

[0037] Preferably, the overall width of the bracket in the radial direction of the clamp can be larger than the diameter of the clamp band. Furthermore, the bracket is preferably designed such that clamp bands with diameters from 80 mm to 600 mm can be used. Even more preferably, the width in the axial direction of the clamp and along its central longitudinal axis is approximately between 20 mm and 35 mm, particularly 30 mm. These measures increase the overall usability of the bracket, so that the invention can also be used with clamps of larger dimensions in the axial direction, such as pipe couplings.

[0038] According to a further preferred embodiment, the clamp band and / or the bracket can comprise a material from material group W1, wherein the clamp band and / or the bracket of material group W1 can be finished by a continuous hot-dip coating process according to DIN EN 10326. This coating process is advantageously not as complex and costly as the aforementioned external electroplating process, which is normally required after spot welding.

[0039] To protect the clamp-bracket configuration from corrosion after application, the clamp band and / or the bracket can be pre-galvanized with a zinc coating. This is a significantly more cost-effective method. Due to the finishing or pre-galvanizing with a suitable pre-galvanizing material, corrosion formation can be effectively prevented during application. Clamps of material group W1 are generally made entirely of coated steel. The coating is equivalent to galvanizing, which actively protects the clamps from corrosion, preferably by acting as a sacrificial anode.

[0040] According to an alternative preferred embodiment, the clamp band and / or the bracket can be made of a material from material group W3, material group W4, material group W5, or material group W6. With the previous spot welding method, the use of material groups W3, W4, or W5 was not possible because increased corrosion could occur locally at the weld points. The use of these material groups particularly improves sustainability and further reduces production costs.

[0041] When using material group W3, preferably both the clamp band and the bracket and other closing parts of the clamp can be made entirely of chrome steel 1.4016.

[0042] When using material group W4, the clamp band, the bracket, and other clamping components can preferably be made entirely of a chromium-nickel or comparable steel. Material W4 is also known as V2A and has the material number 1.4301. It is an austenitic stainless steel and the most commonly used material in many applications. Clamps made of this material advantageously possess high corrosion resistance due to their nickel content and are largely resistant to water, weak organic and inorganic acids, humidity, and steam. They are therefore ideally suited, for example, in beverage and food production, the pharmaceutical and cosmetics industries, medical technology, etc.

[0043] Due to its excellent polishability, W4 clamps are also ideally suited for use in areas that place high demands on the external appearance.

[0044] When using material group W5, the clamp band, the bracket, and other fastening components can preferably be made of various chromium-nickel-molybdenum steels (1.4401; 1.4571), also known as V4A. W5 is difficult to magnetize. The addition of molybdenum advantageously further improves corrosion resistance, making the clamp suitable for use in applications with the highest corrosion resistance requirements. Particular attention should also be paid to the seawater resistance of material W5, which allows for its use in shipbuilding, for example. Material W5 is used in vacuum technology, submarine and furnace construction, the textile, paint, pharmaceutical, and photochemical industries, as well as in wastewater treatment and exhaust gas technology, and significantly expands the clamp's range of applications.

[0045] According to a further preferred alternative embodiment, the clamp band and the bracket can be made of different materials, wherein the clamp band can comprise a light metal and the bracket can comprise a plastic. Alternatively, the clamp band can preferably comprise a plastic and the bracket a light metal. According to another preferred alternative, a carbon material can be used instead of plastic. According to a further preferred alternative embodiment, in addition to an aluminum alloy of material W6, other light metals, preferably a magnesium alloy, can be used. The aforementioned possible combinations can preferably also be combined with one another.The aforementioned design variants are made possible and supported in particular by the fact that the spot welding process mentioned at the outset is no longer used according to the invention, but rather a purely force-fit and / or form-fit fixing between the bracket and the clamp band is present.

[0046] Preferably, the console according to the invention can be connected to various types of clamps and is basically suitable for all hose or pipe clamps.

[0047] According to a preferred design, the console can, for example, be installed on an exhaust pipe clamp according to DIN 71555.

[0048] According to another preferred design, the console can, for example, be installed on a classic clamp or hose clamp.

[0049] According to another preferred design, the console can, for example, be installed on a pipe mounting clamp.

[0050] In a preferred embodiment, the bracket can, for example, be installed on an axially tensile-resistant pipe coupling clamp. Because the pipe coupling clamp has a further axial extension, this embodiment provides a total of four locking structures on the clamp band, two on each side, and four corresponding leg ends that can be inserted into the four locking structures.

[0051] Further features, details and advantages of the invention will become apparent from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings. The drawings show: Fig. 1 a schematic representation of a clamp according to the invention with a fixed bracket, Fig. 2 a schematic representation of a clamp band of the clamp according to the invention with fixed bracket made of Fig. 1, Fig. 3 a schematic representation of a console of the clamp according to the invention with fixed console made of Fig. 1, Fig. 4a a front view of another application of the console according to the invention on an exhaust pipe clamp according to DIN 71555, Fig. 4b a front view of another application of the console according to the invention on a classic tension clamp or hose clamp, Fig. 5 a schematic representation and a front view of a further application of the console according to the invention on a pipe support clamp, Fig. 6 a front view and a side view of a further application of the console according to the invention on an axially tensile-resistant pipe coupling clamp.

[0052] The generally in Fig. Clamp 10 is specifically designed for fastening tubular bodies to a suitable surface (not shown), such as walls or ceilings. Clamp 10 has an axial direction A and a radial direction R.

[0053] The clamp 10 comprises a clamp band 5 with a first and a second clamping head 2, 4, each of which has a through-opening through which a clamping element 3 is inserted to clamp the clamp 10. The clamping element 3 shown is an M10 bolt with nut and thread. The bolt 3 includes a hexagon 3'. The clamp band 5 is equipped with a rubber profile 11, which completely encases the clamp band 5 up to the clamping heads 2, 4 from an inner surface of the band and projects over the axial edges of the clamp band 5, so that the axial edge regions are also surrounded by the rubber profile 11.

[0054] The clamp 10 also has a bracket 20 for fixing the clamp 10 to a suitable base (not shown). The clamp band 5 has two connecting structures 15 for partially receiving the bracket 20, whereby the bracket 20 is fixed to the clamp 10 by interaction with the connecting structures 15 of the clamp band 5. The clamp-bracket configuration shown comprises a total of five individual or half parts. The bracket 20 is positively and force-fitted to the two connecting structures 15 of the clamp band 5.

[0055] By adding the Fig. 2 and Fig. Figure 3 shows that the connecting structures 15 of the clamp band 5 are each formed by two tabs 6 and a locking element 7 as well as a recess 8, wherein the two connecting structures 15 are formed diametrically opposite each other on the circumference of the clamp band 5.

[0056] The console 20 is arranged essentially diametrically opposite the two clamping heads 2, 4 and the clamping element 3. The connecting structures 15 of the clamping band 5 are positioned essentially centrally on the circumference of the clamping band 5 between the clamping heads 2, 4 and the console 20.

[0057] As particularly evident in the individual presentation of the Fig. When illuminated at point 3, the console 20 has a base body facing the suitable surface, with a central curved section 23 and two flat sections 21 adjacent to the curved section 23. Openings are provided in the flat sections 21, through which the clamp 10, together with the installed console 20, can be fixed to the suitable surface. The flat sections 21 of the console 20, as well as the base body as a whole, are arranged parallel to the surface.

[0058] The curved section 23 is form-fitted to an outer circumferentially curved surface of the clamp band 5, the clamp band 5 having two projections 9 that extend radially outwards and engage in openings 9' provided for this purpose in the bracket 20. The curved section 23 rests fully against the clamp band 5, the flat sections 21 being arranged with respect to the radial direction R of the clamp 10 such that they are positioned closer to the suitable support than the curved section 23.

[0059] The console 20 has a first and a second leg 22, 24, wherein the legs 22, 24 are each provided with a first and a second leg end 25, 26, which are designed to be complementary to the connecting structures 15 of the clamp band 5 and are inserted into them to interact.

[0060] The two legs 22, 24 and the leg ends 25, 26 of the bracket 20 partially encircle the clamp band 5, with the legs 22, 24 of the bracket 20 being bent over and projecting towards the connecting structures 15 of the clamp band 5, engaging in the structure for locking and fixing. The legs 22, 24 and the corresponding two leg ends 25, 26 of the bracket 20 are arranged or bent over essentially perpendicular to the flat sections 21. The illustrated bracket 20 is a single piece and made of a single material.

[0061] As can be seen especially in the Fig. 4a and Fig. As can be seen in Figure 4b, the legs 22, 24 and the leg ends 25, 26 are arranged essentially perpendicular to the flat sections 21 of the console 20, but the legs 22, 24 have a slight inclination in the direction of a central longitudinal axis of the clamp 10 of about 2° to 7° and press radially on the clamp band 5, so that it is slightly clamped between the legs 22, 24.

[0062] The leg ends 25, 26 are formed by locking webs 29, wherein the locking webs 29 of the leg ends 25, 26 each extend between a radially inwardly projecting rounded edge 27 in the direction of the central longitudinal axis and a radially outwardly projecting rounded edge 27' (cf. Fig. 3).

[0063] The locking webs 29 are inserted into the connecting structures 15 of the clamp band 5 in such a way that the locking webs 29 are at least partially enclosed by the tabs 6 and form a force-fit and / or form-fit connection.

[0064] The leg ends 25, 26 have a recess 28 for receiving the locking element 7 of the connecting structures 15. The locking elements 7 and the recesses 28 are designed to be complementary to each other. The leg ends 25, 26 also each have a bearing surface 30 that is wider in the axial direction A compared to the locking lugs 29, for bearing circumferentially on the clamp band 5 when the clamp 10 is tightened.

[0065] The overall width of the console 20 is dimensioned larger in the radial direction R of the clamp 10 than the diameter of the clamp band 5.

[0066] The console 20 shown can basically be connected to various types of clamps and is generally suitable for all hose, pipe or cable clamps.

[0067] Fig. Figure 4a shows the console 20, which is fixed to an exhaust pipe clamp according to DIN 71555 as an example.

[0068] Fig. Figure 4b shows console 20, which is fixed to a classic clamp or hose clamp as an example.

[0069] Fig. Figure 5 shows console 20, which is fixed to a pipe support clamp as an example.

[0070] Fig. Figure 6 shows the console 20, which is fixed to an axially tensile-resistant pipe coupling clamp as an example. Because the pipe coupling clamp has a greater axial extent than the other clamp types shown, according to this embodiment, a total of four locking structures 15, two on each side, are provided on the clamp band 5, and corresponding four leg ends are provided on the two wider legs 22, 24, which are inserted into the four locking structures 15 for fixation.

[0071] Furthermore, there are corresponding elements in all Fig. Items 1 to 6 are provided with identical reference symbols and have an identical structure.

[0072] The invention is not limited to the embodiments described above, but can be modified in a variety of ways. In particular, the precise coordination of the material combination, the dimensioning of the clamp / bracket, or the precise structuring and design of the locking structures of the clamp band can vary in such a way as to ensure the required secure and force-fit and / or form-fit fixing of the clamp to the bracket.

[0073] All features and advantages arising from the claims, the description and the drawing, including design details, spatial arrangements and process steps, can be essential to the invention both individually and in various combinations.
