Description

The invention relates to a pipe holder for mounting Pipes along a wall according to the preamble of claim 1 as well to a method for tube assembly using a tube holder according to the preamble of claim 16.

Such pipe holder are used in the plumbing and Heating technology especially for one and two pipe laying at Old building modernization, for surface mounting of pipes behind the foot afford as well as all other areas where Rohrlei lines along walls.

The pipe holders are e.g. known as pipe clamps. These are only suitable for fastening a pipe in a straight line or only slightly bent pipe areas. In the area of wall corners is an attachment of the pipe with such pipe clamps not possible. Furthermore, a relative must in the area of wall corners great effort must be made to get the pipe around the pipe corner to lead. Most pipes can be used in the bend hot state, however, this procedure is very complex and carries the risk of cross-sectional constrictions, so-called white breaks (for plastic pipes) and the like, especially if the desired bending radius is relatively small. In these cases it is necessary to use two straight pieces of pipe by means of an internally hollow angle or arch piece Welding, soldering, gluing or screwing together connect to.

Based on this, the invention is based on the object Laying pipes in the area of wall corners is such a strong one  Deflections of the pipe allow it to be endless can be relocated, d. H. curved or angular Rohrver there are no ties; in particular, the pipe should be behind a Skirting board or the like can be installed.

To solve this problem, a pipe holder with the features of claim 1 and an assembly method with the features of Claim 16 proposed.

The invention achieves, among other things, that

• - Soldering or welding work and thus the risk of damage changes to the home furnishings, wallpaper or carpets and the same (in the case of old building renovation) is no longer necessary
• - Tubes made of copper or mild steel and - as preferred - tubes made of Plastic without the use of welding arches, screwable Contra-angles or the like in inner and outer corners, esp are particularly useful for surface mounting;
• - The pipe so close to the wall in the area of wall corners can be installed, e.g. behind an attachable Skirting board can run;
• - Repair work, especially the replacement of the pipe simple way is possible;
• - fewer leaks can occur;
• - the assembly is simplified and can be carried out more quickly;
• - the load-bearing capacity of the wall is not reduced;
• - Elongations in the longitudinal direction of the tube can be recorded, what however, an appropriate fixation of the pipe to the wall assumes;
• - The noise generated by a Me flowing through the pipe dium is comparatively low.

Appropriate configurations of the subject matter of the invention especially a simple clamping of the pipe in the pipe holder, the best possible protection of the pipe in the bending area, a be particularly simple pipe assembly and / or a simple structure of the Ensure pipe holders are included in further claims.  

The components to be used according to the invention are subject to their Size, design, choice of materials and technical concept no special exceptions, so that in the known selection criteria in each area of application limited use, in particular they are independently of each other to solve the task or at least a subtask can be used to advantage.

Further details, features and advantages of the subject of Invention result from the following description of the associated drawing, in the preferred embodiments Pipe holder according to the invention have been shown. In the Show drawing:

Fig. 5 shows another pipe holder according to the invention (fifth embodiment) in three variants in a perspective view.

In the embodiment according to FIG. 1A to 1C there runs the Rohrhal ter 1 consists of a housing in which a rectangular cross-section, in particular genetic quadra tube channel 2. This pipe channel 2 has the task, for example, to guide and hold a water-carrying pipe 3 made of plastic material so that the pipe 3 can be laid without kinking in an inner wall corner of a wall 4 , for example a residential building, without the pipe 3 in the Corner further from the surface 4 A of the wall 4 protrudes inwards than in those wall areas where the pipe 3 runs straight and is fastened to the wall 4 with known fastening clips. For this purpose, the pipe channel 2 is shaped such that the pipe area 3 A running towards the wall corner is first deflected by approximately 45 ° in the direction of the surface 4 A. Gen in these 45 ° Bo, a 180 ° arc with opposite directions of rotation, and it in turn a further 45 ° bend closes - again with opposite directions of rotation - at. Overall, the direction change of the pipe 3 is 90 °. All angles can of course be chosen freely, in particular the pipe bends can also run asymmetrically. An alternative pipe course is shown in phantom in Fig. 1A.

Due to this - double S-shaped - shape of the pipe channel 2 , it is usually necessary to push a more or less large part of the pipe holder 1 into a correspondingly prepared recess 4 B of the wall 4 . Such a depression can be produced in a simple manner with a circular milling head. If the recess 4 B is initially larger than necessary to accommodate the corresponding area of the pipe holder 1 , the area of the recess which is too large can be filled in with a mortar or the like, the mortar simultaneously fastening the pipe holder 1 in the wall 4 causes.

An optically clean conclusion of the recess 4 B in the area of the surface 4 A of the wall 4 can be achieved by cover strips 5 who are attached to the outside of the pipe holder 1 such that they rest on the surface 4 A of the wall corner in the installed state of the pipe holder . Holes 6 provided in the cover strips 5 can be used for screwing the pipe holder 1 to the wall 4 .

In the embodiments shown in all drawings for a so-called surface mounting of the pipes 3, the pipe holders 1 preferably protrude from the surface 4 A as far as the pipe 3 mounted along the wall 4 protrudes therefrom.

The pipe channel 2 has two opposing, approximately pa parallel holding jaws 2 A and 2 B. These holding jaws extend perpendicular to the bending planes of the tube 3 . Because of all usable tubing to its own elasticity in bending the pipe 3 is always present at the radially inner side surface of the tubular passage 2 forming holding jaw of the tube holder 1, if the diameter of the tube than the distance between the holding jaws 2 A and 2 B is less of each other. The holding jaws 2 A and 2 B thus run approximately parallel to one another and are each bent in the same direction, the bending radius being selected so that the tube 3 can be clamped between the two holding jaws by bending.

Basically, it is possible to provide in the pipe holder 1 a closed over its entire circumference pipe channel through which the pipe 3 can be pushed from one end. However, the more rigid the pipe 3 is and the more the bending radius of the pipe channel 2 approaches the smallest possible bending radius of the pipe 3 , the more difficult such a pushing through is.

The arrangement of the tube 3 in the tube holder 1 is easier compared to the aforementioned simplest embodiment, when the tube channel 2 upwards, ie at right angles to the surfaces of the holding jaws 2 A and 2 B is open or openable. A pipe holder that can be opened in this sense is shown in FIGS. 1a to 1c. The tube 3 is then inserted into the tube channel 2 from above in the hand-bent state and, due to the elasticity of the tube 3, automatically tightens between the holding jaws 2 A and 2 B when the tube is released. The pipe duct 2 can subsequently be closed from above by means of a cover plate 7 . For the exact fixing of the cover plate 7 , fastening pins 7 A are arranged on the underside thereof, which can be inserted into corresponding bores 7 B of the tube holder 1 .

The preferred pipe holder according to FIG. 2 corresponds in its outer shape and the course of the pipe duct to the embodiments according to FIGS . 1a to 1c. The difference to the first embodiment, in this second embodiment, is that the tube holder 1 is necessarily constructed in two parts, with - in the illustrated embodiment - each part having a holding jaw 2 A or 2 B and the two holding jaws in the bending plane of the Tube 3 can be pushed towards or away from each other. In the specific embodiment according to FIG. 2, the tube holder 1 consists of a base body 1 A forming a housing and a bending element 1 B. The base body 1 A has in its area facing away from the wall 4 an opening 8 into which the bending element 1 B can be inserted. Mutually corresponding grooves and tongues 9 and 10 in the base body 1 A or on the flexible element 1 B is a direction accurate pushing allow the flexure B 1 in the main body 1A. The tongue and groove arrangement is preferably provided in pairs on the top and bottom of the bending element 1 B or base body 1 A. At the same time, the tongue and groove arrangement at the rear end can form a depth stop, which prevents the bending jaw from being pressed too far into the base body and thus prevents the pipe from being deformed too far.

In the embodiment according to FIG. 2, the tubular duct 2 prior preferably of two half-shells 11 and 12 is formed that are incorporated in the base body 1, and the bending element 1 B and form a tube channel having an elliptical, in particular approximately circular cross-section, after assembly of these two parts .

When using pipes with a relatively high bending strength, the insertion of the bending element 1 B into the base body 1 A can be facilitated by using a known clamping tool, which engages in corresponding recesses 13 and 14 of the base body 1 A and the bending element 1 B.

The embodiments according to FIGS. 1, 2, 4 and 5 have the advantage that they can absorb to a certain extent the longitudinal expansions and contractions of a tube 3 . This is the case, for example, with the scope already described between the pipe and pipe channel cross section, which allows the pipe to be axially displaceable under certain conditions under suitable conditions. The pipe can also be fixed in a variety of ways at a predetermined point along the pipe holder, e.g. by thickening the pipe or narrowing the pipe duct cross-section, in such a way that a so-called fixed point is created between the pipe and the pipe holder, which directs thermal expansion in the desired direction without to hinder them for the rest.

The particular advantage of the embodiment according to FIG. 2 be that the base body 1 A can then first be inserted into a recess in a wall and fixed there before the pipe 3 is laid in the pipe duct 2 , even if the bending of the Pipe 3 for the purpose of laying in the pipe duct 2 requires such great forces that it is no longer possible to push the pipe through the pipe duct. In addition, the embodiment according to FIG. 2 considerably facilitates the laying of endless pipes.

Incidentally, 1 B, in place of the bending element and a tubular element according to FIG. 5, as will be described further below, are used body in connection with a correspondingly shape-conforming reason which then mainly a protective and / or exerts wall fastening function. Such a rohrför shaped element or the tube inserted therein can also be inserted and / or fixed in position with a insertable into the base body, which can be used several times as a bending tool, or can be fixed on it, and / or held piece.

In the embodiment according to FIGS. 3A to 3C, basically the same principle is used as in the embodiment according to FIG. 2 - but with the difference that the embodiment according to FIGS . 3a to 3c for the laying of pipes in the region projecting outwards Wall corners is used. Components with the same effect are identified accordingly.

The surface surfaces of the pipe holder 1 to be arranged inside the wall 4 can be provided in whole or in part with a corrugation 15 which increases the strength of the connection; only a small section of this is shown in FIG. 3a for the sake of clarity. Such positive connections between pipe holder and wall ensure that the Fe strength of the wall is not weakened by the pipe holder.

The pipe holder according to the invention can be of the most varied Materials, in particular from concrete, gas concrete, plastic, metal or similar materials and combinations of these Materials are manufactured.

A quick connector, plaster or the like can be used to install the pipe holder in an opening milled or mortised in the wall. The cover strip 5 serving as an aperture prevents the binder from escaping from the depression 4 B and at the same time serves as a depth stop, so that the correct installation depth of the tube holder 1 is always achieved; finally, it also offers the possibility of fastening the pipe holder by means of screws and the like.

In the embodiments according to FIGS. 2 to 3c, the tube holder can also be opened again and a new tube can be inserted. For this purpose, the base body 1 A and the bending element 1 B with each other, in particular releasably, can be locked, or - as can be seen in FIGS . 2 and 3a - releasably locked by inserting fastening pins 7 A into holes 7 B ; the fastening pins 7 A and the holes 7 B also have the function of an optimal position fixation.

With two or more pipes to be laid in parallel, the Have a corresponding number of pairs of holding jaws.

The embodiment according to FIG. 4 is suitable for connecting heating bodies or water consumption points to a pipeline running under a baseboard. For this purpose, for the sake of simplicity, two pipe holders, as described in conjunction with FIG. 1B, can be screwed flat onto the radiator or water consumption point having approximately vertical wall 4 in a mirror-image arrangement to one another, e.g. B. by means of through holes. Instead, a uniformly shaped, one-part or multi-part pipe holder can be used for this purpose. The two pipe ends upward from the double pipe holder ra are preferably at the same lateral spacing from one another, such as the pipe inlets of the fitting used, such as a distributor or one or more valves. It is also advisable to let the two upwardly projecting pipe ends emerge from the pipe holder 1 with a bend pointing away from the wall 4 , in order, for. B. to facilitate the connection to the connection fitting. A baseboard ( not specifically shown in the drawing) to be plugged onto the pipe holder 1 can also serve as a cover for the pipe holder.

Referring to FIG. 5, an inventive tube holder 17 may consist also of a tubular element, or - as above beschrie ben - such a tubular element as a component to have. Such a tubular element has a more or less wide tube insertion slot 18 , which extends over the entire length of the tubular element and is so wide that the pipe to be installed , not shown in the drawing for the sake of clarity, into the tube insertion slot - if appropriate, below Overcoming a certain resistance - can be inserted or inserted with a click. Depending on the position and width of the tube insertion slot 18 , at least some of the inner wall areas of the tubular element act as holding jaws. In order to enable rigid and / or resilient pipes to be held, if necessary, as described above, a holding or bending element must be provided for integration into the base body and / or the pipe must be pre-bent accordingly. In the tubular version, the holding element z. B. from an overarching clamp, a strap or the like be. Another way to prevent the pipe from jumping out of the inner bend can be in a rearward opening so that the bending stress presses against the tubular element. - It is understood that also in this embodiment, care must be taken that the dimensions used, such as. B. the tube bending radii to the respective application, such. B. the properties of the pipes to be laid must be adjusted.

In FIG. 5 for simplicity shown three different design options of the tubular member to the same pipe holder - and left unun terbrochenes in the axial direction of pipe, in the middle of a slit in the axial direction of tube and right consisting solely of adjacent pipe clamps tubular member.

According to Fig. 5 18, the Rohreinführschlitz on the right and left ends of the tube holder 1 in about the direction of the axis of the resulting pipe bend, while the Rohreinführschlitz in the central length region of the tubular element 17 comprises approximately toward the center of the resulting pipe bend. The pipe to be inserted into the pipe holder can also be inserted into the pipe insertion slot 18 in this way if the pipe holder has already been fastened to the wall or the like by means of fastening tabs 19 or the like. - Basically, however, it is also possible to have the tube insertion slot in the middle length region of the tube holder point outward from the center of the resulting tube bend or in the direction of the bend axis. Then, however, it is necessary to first clamp the pipe in the pipe holder and only then to fix the pipe holder to the wall or the like - unless the pipe holder is used as in the embodiment according to FIG. 4.
