The invention relates to a pipe holder for fastening pipes to ceilings and walls or the like at a distance from these, with the other features in the preamble of claim 1.

There is a pipe bracket of this type known (US-PS 70 651), in which the two pipe clamp shells as strong metallic fittings are formed, on which the respective shaft piece is formed. that too is designed as a complicated molded part. The respective shaft only has inside, and only roughly, Cylindrical shape in adaptation to the essentially cylindrical plug-in pin. The contained in each shaft, The receptacle receiving the collar here consists of an inner annular groove. Bringing this inner Ring groove is quite complex and expensive. The same applies to the pipe clamp with the pipe clamp shells and the respective shafts. Another disadvantage is that the inner Ringnui does not make it possible you can see from the outside of the respective shaft whether the collar of the piece / cup is already shaped

recorded conclusively and securely within the annular groove is or not If this is not yet the case, difficulties arise when both shells should be connected to each other and secured.

In the known pipe bracket, the connecting means consist of a sliding ring with two-sided, downward-reaching arms, which are assigned corresponding slots on the outside in each shaft and which In addition, on the two plug-in pins, there in the area of the collar, each has a recess to prevent rotation is assigned To establish the connection, the ring is pulled down when the shells are closed, whereby the arms engage positively in the shooters of both shafts and hold the shafts together. Inside, the arms also engage in the recess of the collar while preventing rotation. The pole is with the end to be fixed to the wall, ceiling or the like is an integral part of a screwed in with screws Plate.

These particularities of the known pipe holding vung highlighted in detail above show at the same time their disadvantages. On the one hand, the pipe support is in terms of the pipe clamp with both shells and Shanks complex and expensive. It is very material-intensive. In addition, it is very heavy and requires a considerable amount of money Place. This is especially clear when you look at such dimensions of this known Pipe bracket makes clear that are necessary to z. B. to hang thick heating or water pipes or in to hold otherwise. Another disadvantage is the handling of this known pipe holder, as in the following example should be clarified. A position is assumed in which the two Shells are not yet secured against opening because the ring with the arms is still in the unsecured position Position is seated above, which is illustrated in US-PS 18 70 651 in FIG. In this position is for the assembly person outside not recognizable and clearly whether the axial locking, by engaging in the inner ring groove Collar, i still works and let go of the pipe may or may not be, especially if the distance to the ceiling is not right and at the intermediate piece to change the distance must be rotated so that the intermediate piece is either more on the rod is screwed on or unscrewed therefrom, with respect to the pipe clamp which has not been rotated in comparison. In this adjustment work of the intermediate piece, in which the collar is within the inner ring groove running around, it can happen relatively quickly that the two shells diverge slightly and the inner one Annular groove releases the collar. Then the pipe clamp falls down with the shells opening, depending on the situation at the same time the pipe, and also the locking ring. The assembly person must therefore re-install the pipe bracket assemble. It is advisable to avoid unpleasant repetitions of the type described in the Adjustment of the intermediate piece to hold the two shafts of the shells together at least by hand. In addition So work in a predicament is necessary. Most of the time, there is not enough space to the ceiling to move the shafts by hand to be able to stick together. In order to prevent the problems described, hand movements are necessary that very much are expensive.

Another disadvantage, due to the arms and the grooves in the collar, is that when the distance is set, the Intermediate piece must always be turned into the end position so that the more diametrical slots in the collar are on the same level The slits in the shafts and the arms that engage in them run in a diametrical plane. You can go with So do not make such fine adjustment work on the intermediate piece that a rotation of the intermediate piece around a circumferential angle of less than 180 °.

The invention is based on the object of the pipe holder defined in the preamble of claim Ϊ To improve the species to the effect that it is structurally simpler, cheaper and lighter, while one ίο quick and easy pipe assembly permitted and the Fine adjustment of the distance between Ronrund ceilings or wall there are no limits.

In the case of a pipe holder, this task is of the type defined in the preamble of claim 1 according to the invention by the features a-e in the identification part of claim 1 solved

With the features a, the pipe clamp is structurally simple, cheap and light. This is because it is to be made from a very thin-walled sheet steel part, which means that costs, material usage and weight can be kept very low. The ϊ «low weight also has the effect that assembly can be carried out quickly and easily. In the case of pipe brackets, the use of sheet steel parts is known per se (US Pat. No. 19 37 654).

The feature b is complementary to a with low A high level of strength is achieved in terms of construction and material expenditure and in the area of the shaft Ensuring that the cylindrical plug-in pin is enclosed as completely as possible, so that in this area forces acting transversely to the axis of the plug-in pin can also be transmitted well. This affects z. B. at the wall mounting of pipes or the like.

The feature c also simplifies the design achieved with a reduction in costs. The circumferential slot can be used when forming the Sheet steel part ζ. Β. be introduced by punching, so can be achieved without great manufacturing effort. In addition, the feature c is beneficial in that it makes the assembly particularly is facilitated and simplified, because the fact that the circumferential slots through the entire material of the Half-cylinder shells reaching across, like open windows, are for the assembly person during assembly It can be seen from the outside at any time whether and to what extent the K> agen on the plug-in pin is positively engaged in the circumferential slots intervenes. There is a visual inspection from the outside at every stage. The danger of one on one trusts positive engagement without having to have a visual inspection, and is reliable when it is actually not given Formschiuss then surrender to breakdowns is completely excluded here. As the collar, by the way also has no recesses and with anti-twist protection Means cooperating, is a fine adjustment of the distance ^ between the pipe on the one hand and Deok " or wall, on the other hand, no limit is thereby set. The intermediate piece can also be used for fine adjustment by a circumferential angle that is significantly smaller than 180 ° be twisted.

bo by the feature d is also in this combination achieved a substantial improvement. On the one hand, such a connecting means is structurally very good easy and cheap. On the other hand, the clamping screw can secure a preliminary setting with the assembly, f) 5 by screwing in the clamping screw and both Shafts hold together, but without this already firmly against the plug-in pin to prevent it from rotating press. It is therefore a quick and easy way to

Security setting possible in which both shells are reliable are held together, while the collar reliably engages positively in the circumferential slots and can no longer escape from it and nevertheless the intermediate piece relative to the pipe clamp for adjustment purposes is freely rotatable, so the collar is rotatable in the circumferential slots. In this way, the Assembly is made much easier and faster. When tightened, the clamping screw also acts as an anti-twist device of the intermediate piece. It is known per se for a pipe holder (DE-GM 69 06 297), the two Clamp the shells of the pipe clamp together in the shaft area by means of a clamping screw.

Due to the feature e there is a large area for setting the distance between the pipe on the one hand and Wall or ceiling on the other hand created because the rod on the one hand with one thread end into the Nut part can be screwed in to a greater or lesser extent, and because on the other hand, it is also too adjustable. uäS änuefe Gcwiiidccfiuc the rod more or can be screwed less far into the threaded bushing of the intermediate piece.

The features in claim 2 ensure that the inside of the shank of the pipe clamp recorded length of the plug-in pin is increased, so that particularly good transverse forces and bends in this area can be absorbed by the intermediate piece. This is particularly advantageous when the pipe bracket is used to attach pipes to walls or other inclined parts where the pipe support is subject to lateral forces and bending.

Further advantageous features emerge from claims 3 and 4. A visual inspection window is in the case of pipe brackets known per se (US-PS 13 92 810), which results in a diametrically opposed arrangement results in the visual inspection window of the threaded bushing crrriGSiichcri on the one hand a visual inspection from the outside, how deep the threaded rod is screwed into the threaded bushing, and on the other hand how much screw-in depth possibly still available. For this purpose it can be advantageous if - in the axial direction of the threaded bushing seen - several openings are arranged one behind the other. The design of these breakthroughs at the same time as a receiving opening for the wire assembly, it also enables the raw assembly, in which the The threaded rod has not yet been screwed in, but the intermediate piece is already connected to the pipe clamp is to suspend the pipeline with the help of the pipe clamp and the intermediate piece by means of the retaining wire. If then later the threaded rod is attached in the fastener to the ceiling and into the If the threaded bushing of the intermediate piece is to be screwed in, the retaining wire is pulled out.

The feature in claim 5 is also advantageous. The dowel screw can be a wood screw that is in a Ceiling or wall dowels are to be screwed in and a screw head that can be grasped radially from the outside, ζ. Β. Hexagon head, carries. Instead, the dowel screw can also be designed as a machine screw that z. B. can be screwed into the thread of a self-drilling dowel that is to be introduced into the wall, ceiling or the like. A further advantageous embodiment results from claim 6. This achieves that there is also one provides further length adjustment for the threaded rod to be screwed in, in addition to the end with which the threaded rod is screwed into the threaded bushing of the intermediate piece. The threaded sleeve can also be shortened by sawing if short distances are required.

The features in claim 7 lead to the advantage that you do not have the holding wire when assembling the wire only sticks through the openings in the threaded bushing of the intermediate piece, but rather on the wall or ceiling side anchored to the brackets of the nut part, preferably pulling through its openings. In In this context, the features in claim 8 can also be advantageous.

Further advantageous features emerge from patent claims 9 and 10. Such a design is known per se (DE-GM 69 06 297), with a flexible material as damping and insulating material, especially rubber is used. The above-mentioned claim features essentially result in a seamless and self-contained ring with the advantage of good thermal insulation and Sound insulation, as there are no thermal bridges whatsoever or Schaübrücke :; in the area of the Pipe. It is also advantageous that this results in a clean and exact adaptation to the area of curvature every pipe clamp shell is possible. namely like this. that both half-shells of the damping and Connect the insulating shell to one another without any gaps in the area of the diametrical division plane.

Further advantageous features emerge from patent claims 11 and 12. In itself, it is with Rohrhaltercrunysn known (DE-GM 69 06 297), the radial cross-sectional thickness of the damping and insulating shell all around to design consistently. It is advantageous due to the features of the claim that the radial incisions of both half-shells when inserting each half-shell into the associated pipe clamp shell, a clean and allow precise adaptation to the curvature of the pipe clamp shell and the pipeline, so that ensured is that along the inner shell peripheral surface c and on the outer shell peripheral surface c one extensive contact on the one hand with the outer wall of the pipe and on the other hand with the inner wall the pipe clamp shell takes place, so air gaps are essentially completely eliminated.

The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawings explained. It shows:

The in F i g. The pipe bracket shown 1—7 is for attachment a tube 10 is used on a ceiling 11 at a distance from the latter. The pipe bracket has a Pipe clamp 12, which consists of two approximately semicircular Pipe clamp shells 13 and 14 are formed with associated bracing shafts 15 and 16, respectively. The pipe clamp 12 is made of galvanized sheet steel and has, in the usual way, a molded, essentially all-round reinforcing bead 17.

Both pipe clamp shells 13 and 14 are in the area of curvature at the end facing away from the shafts 15, 16, about a later with reference to FIG. 4 clamp lock explained in more detail and also in the area of the shafts 15, 16 via a clamping screw that extends transversely through both shafts 15, 16 and clamps them together connectable and connected in the fully assembled state. The pipe clamp 12 also has one with the latter Load-bearing connectable rod in the form of a threaded rod 19, which is continuously provided with an external thread 20 is provided. The end shoulder of the threaded rod 19 facing away from the pipe clamp 12 is secured by means of a fastening means 21 (Fig. Ib) on the ceiling 11 load-bearing anchorable.

Part of the pipe bracket is also a one-piece, metallic intermediate piece 22, which on one, in F i g. 1 a -ind F i g. 2 lower end one essentially cylindrical plug-in pin 23 with an annular collar 24 protruding radially all around and on the other End of a threaded bushing 26 provided with an internal thread 25 for screwing in the threaded rod 19 wearing.

Each shaft 15, 16 of the pipe clamp shells 13 and 14 has a semi-cylindrical shell above the clamping screw 18 27 or 28, which is shaped in cross section to correspond to the cylindrical shape of the plug-in pin 23 for embracing on all sides and - when tightening the clamping screw 18 - for clamping the plug-in pin 23. Each half-cylinder shell 27, 28 has flat legs 29, 30 and 31, 32, which protrude approximately radially at both ends, which are dimensioned accordingly in cross-section to absorb load forces.

Each half-cylinder shell 27, 28 has one up to two flat legs 29, 30 and 31, 32 reaching Circumferential slot 33 and 34, respectively. The collar 24 of the plug-in pin 23 extends into the peripheral slot 33 and 34 radially in (Fig. 6.7). The collar 24 is within the circumferential slots 33, 34 when the clamping screw is loosened 18 freely rotatable as a result of the rotation of the intermediate piece 22 for purposes of adjusting the distance, but in the axial direction form-fitting anchored

The intermediate piece 22 has on a length paragraph, namely in the area between the threaded bushing 26 and the approach of the plug-in pin 23, a tool engagement surface in the form of an integrally formed hexagon 35. The plug pin 23 carries at the end that the Collar 24 and facing away from the threaded bushing 26, an extension pin 36 of the same diameter, which ends at a small distance above the clamping screw 18 and for better guidance and transmission of shear forces and bending moments.

In its jacket, the threaded bushing 26 has several openings 37 diametrically opposite one another and running at a distance from one another in the axial direction. which serve as a visual inspection window for the screw-in depth of the thread unions 19 and at the same time are designed as receiving openings through which a Hall wire can be inserted for the rough assembly. which can then be anchored with its other end on the fastening means ■> 2i of the ceiling 11. This retaining wire is not shown. It is used when a so-called wire assembly is planned as an intermediate stage before screwing in the threaded rod 19.

As can be seen from Fig. Ib, the fastening means 21 for anchoring the threaded rod 19 to the ceiling 11 with a nut part in the form of a Internal thread 38 provided threaded sleeve 39 into which the threaded rod 19 with its pipe clamp 12 is the opposite end can be screwed in. The threaded sleeve 39 is an integral part of a dowel screw 40 with a hexagonal head 41 for attack by a tool. This one-piece fastening means 21 is with ilci Dfibeischraubc 40 in a dowel 42 within the Ceiling 11 screwed in.

The other embodiment according to FIG. 8 differs from that according to FIG. Ib only in that in FIG. 8 the dowel screw not as a wood screw, but instead as a machine screw is designed, which is in the internal thread of a self-drilling anchor, not shown, which is in the ceiling 11 is anchored, can be screwed in.

In another embodiment, not shown, the nut part into which the threaded rod 19 can be screwed in, designed so that it can be used directly or indirectly, e.g. B. with the interposition of compensation devices, Can be anchored to the ceiling, a wall or the like. There are many possibilities here which can be taken from the state of the art. Like F i g. 1 b shows, the threaded sleeve 39 has openings 43, of which two are preferably arranged diametrically opposite one another. A retaining wire can be inserted through the openings 43 during the rough assembly, which wire can be inserted at the other end is pulled through the openings 37 of the intermediate piece 22.

As in particular F i g. 1a shows the pipe clamp 12 in the inner area of the two pipe clamp shells 13 and 14 with a circular ring-shaped shell running all around 44 lined with insulating and damping material, which is preferably glued in place. The shell 44 is off two half-shells 45 and 46 assembled and in the diametrical dividing plane of the pipe clamp 12 without any gaps closed. Each half-shell 45, 46 is precisely shaped into the associated pipe clamp shell 13 or 14 fitted. It runs with its end faces within the diametrical division plane, which runs through the longitudinal center axis of the intermediate piece 22 and the threaded rod 19. In the tension-free, In the unassembled state, both half-shells 45, 46 can with their end faces also protrude slightly beyond this division plane so that the pipe clamp shells are then clamped together 13 and 14 given a gap-free connection within the diametrical division plane is. Fi g. la shows that each half-shell 45 and 46 successive in the circumferential direction at equal angular intervals Has radial incisions 47 from the inner shell circumferential surface. which spans the pipe 10, go out and at a distance from the outer shell circumferential surface with which the half-shells 45,46 to the Pipe clamp shells 13 or 14 rest and are glued, end.

ker and with sufficient distance to be able to insert the intermediate piece 22 from above. The intermediate piece 22 is with its plug-in pin 23 and the collar 24 in the of the half-cylinder shells 27, 28 limited space large enough in diameter inserted so far that the collar 24 fits into the circumferential slots 33 and 34 of the semi-cylindrical shells 27 or 28 engages radially so that the intermediate piece 22 is anchored axially within the pipe clamp 12 is, but can be rotated about its longitudinal axis. The clamping screw 18 is now tightened further, however not yet finally tightened so that the intermediate piece 22 still remains rotatable. The threaded rod 19 may have previously been cut to the desired length determined by the hanging distance, likewise - with the desired short hanging distance - also part of the threaded bushing 26 and, if necessary, also the threaded sleeve 39 of the fastening means 21. One end of the threaded rod 19 is inserted into the threaded sleeve 39 of the screwed in the ceiling 11 anchored fastening means 21 and secured therein, for. B. by means of not shown Lock nut. Then the threaded rod 19 with the other egg is thereby in the threaded bushing 26 of the intermediate piece 22 is screwed in that the intermediate piece 22 acts on the hexagon 35 by means of a Tool is rotated. As a result, the non-rotatably arranged threaded rod 19 screws into the Threaded bushing 26 into it. The screw-in depth of the threaded rod 19 is through the openings 37 of the threaded bushing 26 can be locked through from the outside. Is the desired cutting distance through correspondingly deep When the threaded rod 19 is screwed into the threaded bushing 26, the clamping screw 18 can be tightened are tightened so that the semi-cylindrical shells 27, 28 with their cylinder inner surface the plug-in pin 23 firmly clamp between them and a rotation of the intermediate piece 22 is reliably prevented. The assembly is completed

The procedure is roughly the same if the pipe 10 is at a distance from a vertical wall or an inclined part.
