Description

[0001] The invention relates to a mounting system for a plurality of pipe clamps, comprising a base strip having a plurality of cylindrical screw receptacles distributed over a length of the base strip, in which head screws can be fixed, which are designed to penetrate and secure at least one row of pipe clamps on the base strip, wherein the head screws are provided at least partially on their screw heads with upwardly open screw receptacles for fixing further head screws of a further row of pipe clamps adjoining in the vertical direction, and comprising at least one cover plate which extends over the cover dimensions of an individual pipe clamp and has passages for head screws. The invention also relates to a mounting strip for such a mounting system.

[0002] Such a mounting system is known from the FKB GmbH product catalog "2+5 ... The System!". This well-known mounting system features a metal base strip onto which several evenly spaced cylindrical screw receptacles are fixed. The screw receptacles are formed by cylindrical bushings, each with an internal thread. In addition, several head screws are provided that penetrate the pipe clamps and are connected to the screw receptacles of the base strip. This makes it possible to position a large number of pipe clamps on top of one another and next to one another. Cover strips, each corresponding to the width and depth of a pipe clamp, are provided with openings through which the head screws can penetrate to fix the cover strips to the upper end faces of the pipe clamps. The pipe clamps are designed to secure different pipe diameters.

[0003] The object of the invention is to provide a mounting system and a mounting bar of the type mentioned above which, compared to the prior art, allows greater variability for the use and positioning of different pipe clamps.

[0004] This object is achieved for the mounting system in that at least one mounting strip is provided which extends at least across the width of a pipe clamp and which is provided with at least one screw receptacle and at least one passage for a head screw, the passage being dimensioned such that a screw head of a head screw can be accommodated. This enables improved positioning, in particular of small pipe clamp sizes. Preferably, the mounting system according to the invention is provided for only two different pipe clamp sizes, which cover a variety of pipe diameters, preferably between 6 mm and 42 mm. The two different pipe clamp sizes are understood to be the outer dimensions of the pipe clamps. Corresponding inner diameters are of course adapted to the variety of different pipes between preferably 6 mm and 42 mm.The at least one mounting strip extends at least across the width of a single pipe clamp. However, the mounting strip can also extend across multiple pipe clamp widths. A correspondingly long mounting strip makes it possible to position a small pipe clamp size over the axis of a large pipe clamp size. This is not possible with the prior art. The screw receptacles are advantageously designed as cylindrical bushings that are applied to an upper side of the mounting strip, in particular by welding or soldering. The cylindrical bushings serving as screw receptacles each have an internal thread that is matched to a cylindrical external thread of a corresponding head screw to enable the head screw to be screwed in.If the cap screws themselves are provided with screw receptacles in the area of ​​their screw heads, it is possible to screw another cap screw coaxially from above into the screw head of the underlying cap screw. The passage is designed to be large enough that edges of the passage flank a screw head of a cap screw. The dimensions of the passage are therefore dimensioned such that they correspond at least to the dimensions of the screw head of the cap screw. According to the invention, a significantly improved positioning is possible, in particular of the smaller pipe clamp sizes. The pipe clamps themselves are advantageously each designed from two plastic half-shells in the shape known from the prior art.

[0005] In one embodiment of the invention, the passage is dimensioned such that a threaded bolt of a cap screw can be passed through. This design allows a threaded bolt of a cap screw to penetrate the passage, whereas a screw head of the cap screw would rest on an edge of the passage.

[0006] In a further embodiment of the invention, the passage is open toward one long side of the mounting strip. This makes it possible to slide the mounting strip from one side over a pre-installed screw head of a cap screw of the mounting system. This enables improved positioning of pipe clamps.

[0007] In a further embodiment of the invention, the mounting strip extends over a length corresponding to several times the width of a pipe clamp, and several passages and several screw receptacles are alternately distributed along the length of the mounting strip. The passages are preferably dimensioned such that only threaded bolts of cap screws, but not the screw heads of the cap screws, can pass through them. The screw receptacles are preferably designed as cylindrical bushings that are fixed to the top of the mounting strip and each have an internal thread for screwing in a threaded bolt of a cap screw.

[0008] In a further embodiment of the invention, each screw receptacle has an internal thread matched to the screw bolts of the cap screws, and each screw receptacle has a cylindrical outer contour. As already stated above, the screw receptacle is preferably designed in the manner of a cylindrical bushing with a corresponding internal thread and a cylindrical outer contour.

[0009] In a further embodiment of the invention, each cap screw has a screw head with a cylindrical outer contour. The cylindrical outer contour enables the function of a cylindrical bushing, meaning that it is possible for another pipe clamp to be attached to a corresponding screw head.

[0010] In a further embodiment of the invention, several cap screws have internal tool engagement surfaces, particularly in the form of a hexagon socket, instead of upwardly open screw receptacles. This allows the cap screws to be screwed in or out using a suitable tool.

[0011] Further advantages and features of the invention emerge from the claims and from the following description of preferred embodiments of the invention, which are illustrated with reference to the drawings. Fig. 1 shows a perspective view of a first embodiment of a mounting system according to the invention, Fig. 2 also shows a perspective view of a further embodiment of a mounting system according to the invention, Fig. 3 in a cross-sectional view the assembly system according to Fig. 1, Fig. 4 in a cross-sectional view of one to Fig. 2 opposite side of the mounting system according to Fig. 2, Fig. 5 shows a perspective view of a long mounting rail for the mounting system according to the Fig. 1 and Fig. 3 and Fig. 6 to 8 different short mounting strips for the mounting system according to the Fig. 2 to 4.

[0012] A mounting system 1a, 1b according to the Fig. 1 to 4 has a plurality of large pipe clamps 5 to 5''' and a plurality of small pipe clamps 6 to 6''''', which are arranged on the basis of the Fig. 1 to 4. The large pipe clamps 5 to 5''' have the same external dimensions. They differ only in their internal diameters, which are matched to the corresponding pipe diameters to be secured by the pipe clamps 5 to 5''' and 6 to 6'''''.

[0013] The mounting system 1a according to Fig. 1 has a total of six large pipe clamps 5 to 5''' and eight small pipe clamps 6 to 6'''''. The mounting system 1b according to the Fig. 2 and Fig. 4 has five large pipe clamps 5 to 5''' and six small pipe clamps 6 to 6''''. Each of the pipe clamps 5 to 5''' and 6 to 6''''' has the same structure. Each pipe clamp is formed by two pipe clamp halves which - in an assembled state - sit on top of each other along a horizontal parting plane. Both half-shells each have an approximately semi-cylindrical recess which, when assembled, forms the cylindrical recess in which the respective pipe is accommodated. All pipe clamps 5 to 5''' and 6 to 6''''' are made of plastic and are each fixed with two head screws which penetrate the respective pipe clamp from top to bottom on opposite sides next to the cylindrical receptacle for the respective pipe.

[0014] The two mounting systems 1a and 1b have identical base strips. Each base strip 2, 2a extends over a length of at least six large pipe clamps arranged side by side, with the pipe clamps 5 to 5''' being fixed in their widthwise extension to the respective base strip 2, 2a. For this purpose, each base strip 2, 2a has a plurality of screw receptacles 11, 11a distributed over the entire length of the base strip 2, 2a, which are mounted in a cam- or bush-like manner on the base strips 2, 2a, which are made of metal, preferably steel. Each screw receptacle 11, 11a is provided with an internal thread into which a head screw 8 or 9 can be screwed from above. The screw receptacles 11 and 11a are preferably applied to a surface of the base strip 2, 2a in a material-to-material bond by welding or soldering.

[0015] As shown by the Fig. 1 to 4, a row of large pipe clamps 5 to 5''' arranged next to each other is placed on the respective base strip 2, 2a.

[0016] In order to be able to position another row of pipe clamps, in this case small pipe clamps 6 to 6''''', in a vertically higher plane, the two mounting systems 1a and 1b are assigned mounting strips 3, 3a to 3c ( Fig. 5 to 8). The mounting strip 3 is a strip-shaped metal plate part that extends over a depth of the large pipe clamps 5 to 5''' and a total length of six adjacently arranged pipe clamps 5 to 5'''. The mounting strip 3 is based on the Fig. 5. The mounting strip 3 has a plurality of screw receptacles 13 distributed over a length of the metallic mounting strip 3. In each group, three screw receptacles 13 are evenly spaced from one another. Between these three screw receptacles 13, two passages 12 are provided alternatingly, which penetrate the mounting strip 3 as bores. The screw receptacles 13 are held in unspecified bores in the mounting strip 3. Each screw receptacle 13 is designed as a cylindrical bushing provided with an internal thread. Each screw receptacle 13 is firmly connected to the mounting strip 3, preferably welded or soldered to the mounting strip.

[0017] Based on the Fig. 1 and Fig. 3 it can be seen that the mounting strip 3 is placed on the top side of the six large screw clamps 5 to 5''' arranged next to one another and is fastened to them by means of head screws which penetrate the underlying large pipe clamps 5 to 5'''.

[0018] The head screws 8 protrude through the passages 12 of the mounting strip 3, whereby corresponding screw heads of the head screws 8 are supported on the upper side on an edge of the respective passage 12 of the mounting strip 3.

[0019] The smaller pipe clamps 6 to 6'''' are also fastened to the mounting bar 3 using - albeit smaller - head screws 7, whereby the head screws 7 are each screwed into the bush-shaped screw receptacles 13 of the mounting bar 3.

[0020] For the mounting system 1b according to the Fig. 2 and Fig. 4, a total of five separate mounting strips 3a to 3c are provided, which are arranged on the basis of the Fig. 6 to 8. As can be seen from the Fig. 2, 4 and 6 to 8, each of these mounting strips 3a to 3c extends only over the width of a single large pipe clamp 5 to 5'''. Depending on which mounting strip 3a to 3c is used, it is possible to mount at least one small pipe clamp 6 to 6''''' on the respective lower large pipe clamp 5 to 5'''. Each of the mounting strips 3a to 3c has at least one screw receptacle 13, which is designed in a bushing-like manner similar to the screw receptacles of the mounting strip 3 and is provided with an internal thread. The respective screw receptacle 13 protrudes analogously to the screw receptacles 13 according to Fig. 5 extends upward from the top side of the respective mounting strip 3a to 3c. The mounting strips 3a to 3c are also each designed as metallic plates, preferably as steel plates. The fastening of the at least one screw receptacle 13 to the respective mounting strip 3a to 3c takes place in the same manner as previously described with reference to the mounting strip 3.

[0021] Like the Fig. 6 to 8, the two mounting strips 3b and 3c ( Fig. 7 and Fig. 6) each have a single, centrally arranged screw receptacle 13, whereas the mounting strip 3a has two screw receptacles 13 arranged mirror-symmetrically to a central transverse axis of the mounting strip 3a. In the mounting strip 3a, the two screw receptacles 13, which are symmetrically offset outwards relative to the center, are each flanked on the outside by a respective passage 15, which penetrates the mounting strip 3a as a bore. The diameter of the respective passage 15 corresponds to a screw bolt of a head screw 7, 8, i.e. the diameter is slightly larger than an outer diameter of the external thread of the screw bolt of the respective head screw 7 and 8, but smaller than the screw head. Each head screw 7, 8 has a cylindrical screw head which is provided either with an upwardly open blind internal thread or with tool engagement surfaces, in particular with a hexagon socket.

[0022] The construction strip 3b according to Fig. 7 has a centrally arranged, bush-shaped screw receptacle 13 and a laterally offset passage 15, which is identical to the passages of the mounting strip 3a according to Fig. 8. Opposite the passage 15, however, the mounting strip 3b is provided with a larger passage 14 that is open to the side. The passage 14 has a width that is slightly larger than the outer diameter of a screw head of one of the cap screws 7 and 8.

[0023] The mounting strip 3c according to Fig. 6 has two such passages 14, which are each open to the outside towards opposite outer sides and whose width is slightly larger than an outer diameter of the screw head of the respective head screw 7, 8. The mounting strip 3c is also provided with a centrally arranged screw receptacle 13, which is designed identically to the screw receptacles 13 according to the mounting strips 3, 3b and 3a according to the Fig. 5 and Fig. 7, Fig. 8.

[0024] Based on the Fig. 2 and Fig. 4 it can be seen that the small pipe clamps 6 to 6''''', which are positioned in a second row above the large pipe clamps 5 to 5''', can be positioned and fixed either centrally to the respective pipe clamp 5 to 5''' below or laterally offset to the respective pipe clamp 5 to 5''' below. For a laterally offset fixation, as is the case with the pipe clamps 6", 6''', 6''''' according to the Fig. 2 and Fig. 4 is the case, the cap screws 7 provided with the screw heads 10 are each partially screwed into an internal thread of a screw head of a cap screw 9. In this case, Fig. 2 and Fig. 4 also shows which of the mounting strips 3a to 3c are required for this. If one of the upper head screws 7 of the upper pipe clamps 6 to 6'''' is to be screwed into the internal thread of the screw head of the underlying head screw 9, a mounting strip 3b or 3c is used which has a large, laterally open opening 14 so that the mounting strip can be pushed sideways over this screw head. The other head screw with its other screw head 10 is screwed into the central screw receptacle 13 of the mounting strip 3b or 3c. For the upper pipe clamp 6 which sits centrally on the lower pipe clamp 5, the mounting strip 3a is used which has two adjacent screw receptacles 13 into which the head screws 7 with their screw heads 10 can be screwed.The adjacent passages 15 serve to accommodate the head screws 8, which fix the mounting strip 3a to the underlying pipe clamp 5. The small pipe clamp 6", which is positioned centrally between two adjacent pipe clamps 5 and 5''' of the underlying pipe clamp row (in . Fig. 2 the third pipe clamp 6" from the right, in Fig. 4 the third pipe clamp 6" seen from the left), the mounting bar 3c is Fig. 6. The adjacent lower, large pipe clamps 5 and 5''' are each connected to the base plate 2a via head screws 9, the screw heads of which are provided with internal threads open at the top. Fig. 4 it can be seen that the head screws 7 with their screw heads 10 are screwed into these screw heads of the head screws 9 from above, which inevitably results in the fixation of the upper pipe clamp 6" relative to the lower row of pipe clamps 5, 5'''.

[0025] The assembly system 1a, 1b thus comprises, in addition to at least one base strip 2, 2a, which are designed identically to one another, a total of four different mounting strips 3, 3a to 3c, which are Fig. 5 to 8. In addition, a plurality of head screws 7 to 9 are provided, some of which are provided with upwardly open internal threads in the area of ​​their screw heads. The head screws 9 have external tool engagement surfaces, in this case each an external hexagon. The remaining head screws 7 and 8 only have different lengths of their screw bolts with corresponding external threads, but are otherwise identical to one another. All head screws 7 and 8 are provided with cylindrical screw heads 10, which have upwardly open tool engagement surfaces on the inside. In the illustrated embodiment, these tool engagement surfaces are designed as hexagon sockets.

[0026] These components of mounting systems 1a and 1b can be combined in any number depending on the desired installation concept. All additional cover strips 4 required for attaching to the small pipe clamps 6 to 6''''' are identical in design.
