Abstract

A groove (13) along one of the metal tubes (11) is engaged forcibly and/or positively by a number of metal holders (12), the tube groove extending over the tube thickness and undercut for engagement by a coupling element (16) forming part of the holder (12). The element should be as long as the tube (11) and in strip form, having appropriately spaced coupling points. The holder (12) head (18) is enclosed at its neck (19) by the suitably recessed part of the coupling element. The coupling strip (16) is shaped as flat plate or C-profile in which case the neck hole is adjoined by an additional hole to admit the diameter of the holder head and is bounded here by strip tabs. The coupling thus hooks resiliently into the partly circular groove of the tube (11) and is itself a partial sphere slotted out in the centre to reach out close to the tube insulating wall (14). In the case of a rectangular groove (13), the coupling consists of parallel holder (12) clamping surfaces to fit in between the walls of the groove.

Description

The invention relates to a composite profile in Rah of wall elements, doors and windows, with metal pipes, the rigidly spaced apart by metal holders who are connected, facing each other in recesses Intervene profile walls, and with at least one the metal holder enclosing layer of fire-resistant insulating material material that at least the distance between the metal pipes partially filled.

A composite profile with the aforementioned features is out known from DE 33 24 210 C2. The two metal pipes and that insulating material arranged between the two are by means of through screws or rivets. The latter each enforce both adjacent to each other in inner tube walls. For inserting the screws or rivets but at least the outer wall of one of the pipes must be relative large holes are provided around the screws or rivets to be able to attach. The assembly of the composite profile is consequently expensive and the outside of the composite profile Visible holes must be covered with additional cover profiles be covered. In the aforementioned publication is therefore suggested the best of weldable material existing metal pipes to connect to each other by metal webs to those who enforce the insulation material and both  the pipe wall facing the insulating material is welded are. To carry out the welding is a complex Conveyor required, which the metal webs between position the pipe walls facing each other. At different positions of the metal bars between the Pipe walls to be joined together are considerable Retrofitting of the facility required.

The invention is based on the object a composite profile with the characteristics mentioned above improve that its manufacture even without considerable Ma is possible, but on the other hand a leg impairment of the appearance through mounting holes or the on set of additional cover profiles can be avoided.

This object is achieved in that at least one Metal tube on a longitudinal groove as a recess points in which a variety of metal holders force and / or intervene positively.

While in the known composite profile holes as from acceptances are used to connect them To couple the metal pipes through the metal holder, it is for the proposed composite profile of importance, one lengthways continuous groove. With the help of this groove the metal holders are attached to the metal pipes, and in different ways, non-positive and / or positive sig. The type of training of the metal holder depends on the Type of formation of the groove that is profiled differently can be. In addition, the groove has the advantage that it forming walls contribute to the stiffening of the metal pipe. As a result, the groove opens up a variety of mechanical loading Fixing options, from which the right one depending on the con structural need can be selected. Beyond that from the groove offers as a continuous construction element ment the possibility to change the metal holder without modification Metal pipe in the places given for construction reasons freely selectable. For example, it is possible To change distances, the equidistant metal holder of one have other. But it is also possible to use the metal holder  to be arranged with different distances from each other to the Adapt the connection strength to the structural conditions sen, namely, for example, closely spaced metal neck ter in structurally highly stressed areas or further mutually or staggered metal holder for installation in to be able to make the space between the metal pipes. Here it is also easily possible to distinguish metal holders training to use different connections to achieve tensile strengths. That is especially before partial if the metal holder different manufacturers exhibit costs.

The groove of a metal pipe used for fastening can in the manufacture of the metal tube with comparatively ge produced with little effort, e.g. B. in an extruder process or during a deformation process, namely by whale zen or roles. It is therefore advantageous to use the composite profile Form so that the groove of the metal tube from its wall is formed in full wall thickness. A complex change The wall thickness in the area of the groove can then be omitted.

The composite profile is advantageously formed if the groove of the metal tube is undercut and the metal holder has at least one undercut as Wi the bearing utilizing coupling element. As a result The metal holder with positive coupling elements can be used elements are provided. The design of the clutch elements on the cross-section of the groove or on its rear adapted to the cut. Cross-sectional designs can be used be set that allow a quick connection, others on the other hand, the necessary connecting forces are possible chen.

The seat of the metal holder in the groove of the metal tube in The longitudinal direction of the groove can be secured by frictional engagement. It but it is also possible to design the insulating material in such a way that there is a shift from loose in the longitudinal direction gripping metal holders does not allow. For example se achieved in that the insulating material the metal holder tightly encloses and supports.  

The composite profile can be designed so that the Coupling element a coupling that is long according to the metal pipe strip with the design requirements accordingly spaced coupling points. With the help of the clutch The bar can be used with metal brackets that have no width res with her head through the slot of the undercut Slot. The coupling strip takes over positive connection between the head of the metal holder and the metal pipe. The design of the coupling bar can be adapted to the respective connection requirements that, for example in the sense of high connection strength or low material consumption.

In the aforementioned sense, the composite profile designed that the metal holder each with a head are provided on the neck of the coupling bar with a recess corresponding to the neck diameter is grasped. Metal holders with head and neck are basically one multiple bolts with an annular groove and consequently mass-produced suitable parts. The outside diameter of the head is just as big as the one between the metal tubes kende shaft diameter, which is about the slot width of the groove corresponds to the metal pipe.

Around the coupling bar with one head It is easy to assemble the metal holder the composite profile designed so that the coupling strip a plate-like flat or a rectangular or C-shaped has a profiled design, in the longitudinal direction alongside the recess with the neck diameter at least one diameter plug opening is arranged with the head diameter. The To assembly process of a coupling strip with a metal holder or with all metal holders can be done in a simple manner achieved that the metal holder with his head through the push-through opening is installed, after which a shift Exercise the coupling strip ensures that the neck Recess with a diameter when the dome is installed in accordance with the intended purpose concentric to the metal holder is arranged so that the coupling strip against the head  Pulled out of the groove locked. The plate-like flat Design of the coupling strip is a constructively simple che solution and the C-shaped design of the Coupling strip enables a shift with comparative wise larger forces without the risk of deformation, the the assembly with the variety of metal holders affect could be pregnant.

To the position of the metal holder relative to the longitudinal direction To secure the groove, the composite profile can be trained det be that the recess of the coupling strip of the Pushing through the head allowing its retraction preventing inguinal flap is limited. The inguinal flap clamps on the head of the metal holder, so that this can't move.

The above-described configurations of the metal holder act positively without deformation. Demge Compared to this, the composite profile can also be designed in this way that the coupling element resiliently hook-like in the groove of the metal pipe engages. As a result of the hook-like resilient The coupling element engages in the groove latching engagement or a latching engagement that is also powerful can be conclusive. In particular, it can prevent the Metal holder is loose in the direction of the groove. It also has this design of the composite profile the advantage more optimal Simplicity. There are no other parts to hold the me tall holder or his head in the groove required. To the Simply assemble the composite profile sen to make the locking connection.

The composite profile described above can thereby continue forms that the groove of the metal tube is part-circular Has cross section, and that the coupling element is part-spherical is formed and in the middle at least one slit-like ker be, which is close to the insulating material term pipe wall extends. The part circular cross section Formation of the groove is the part-spherical configuration the coupling element optimally adapted. The latter is a consequence its design with inclined surfaces that the one  press into the groove of the metal pipe. This serves also the slot-like notch, which the rebound of the dome Lung element allows.

If the composite profile with only non-positive to be trained against metal holders, it has the characteristic le that the groove of the metal tube has a rectangular cross-section, and that the coupling element parallel to each other, between the Groove walls are suitable clamping surfaces of the metal holder. Also this composite profile can be arranged according to its metal holder in the insulation material by simply compressing the metal Pipes are made so that the clamping surfaces on the groove stuck to the walls of the metal pipe.

To make the clamping surfaces as large as possible, others on the other hand, mass-production-oriented and little material expenditure To be able to use the metal holder becomes the composite profile formed so that the metal holder is a square bolt.

If the groove bottom of the metal pipe with its outer wall The composite profile is supported by a metal bar for comparatively large clamping forces between the metal neck ter and the metal pipe because the metal web the Groove walls against shifting when stuck lized.

A composite profile with the features mentioned above can also solve the above problem forms that isoliermate in at least one metal tube at least one cap screw is screwed on the radial side whose head, if necessary, is a tube or a piece of tube formed metal holder is coupled. Such Ausge Design of the composite profile is particularly advantageous liable if the arrangement of a groove in the metal pipe for reasons otherwise profiling this pipe is not shown. It is then only a threaded hole in the tube wall nes metal pipe into which the cap screw is inserted can be screwed. The head can be used to connect the Me tall holder can be used, which in constructive advantage can be designed in a way. It is preferable to use an as  Pipe or pipe piece trained metal holder because of the In nominal diameter of the pipe in a technically simple Adapted for coupling to the head of the cap screw can be.

It is particularly advantageous to do the composite profile like this design that the metal holder on the head of the head screw is locked. The locking connection can be trained in this way det that the assembly of the composite profile by Zu push the metal pipes together when in the positive position nated pipes or pipe sections.

The invention is based on Darge in the drawing presented embodiments explained. It shows:

Wall elements, doors and windows usually consist of frames in which frame panels are inserted. The frames must give the component in question the required stability. If the wall elements, doors and windows are to be fire protection components, i.e. if they are to be fire or heat resistant according to the relevant regulations, special insulation measures must be taken. In view of this, a composite profile 10 according to FIGS. 1 and 8 to 10 consists of two metal tubes 11 designed as hollow chamber profiles. The metal tubes 11 are only executed for example in the figures. They can be adapted in detail to the respective profile system which, for example, wall anchoring elements, glass holding elements, seal holding elements, frame flaps, drive rod grooves and the like. Like. Has. The designs mentioned above, for example, can also be distributed over the composite profile 10 as a whole, which consists of two spaced-apart metal tubes 11 and at least one layer 15 of insulating material. The insulating material is fire-resistant dig and completely fills the distance between the metal tubes 11 in the embodiments. It also serves as a spacer. Instead, however, it is also possible to fill out the space between the metal tubes 11 only in sections, that is, either transversely between the metal tubes 11 or in the longitudinal direction thereof. It is also possible to use more than two metal tubes 11 with several layers of insulating material, for example three metal tubes 11 , each with one layer between two metal tubes. The exemplary embodiments for composite profiles 10 thus represent construction principles that can also be used, for example, in composite profiles in which a frame rail has three metal tubes 11 .

In order to mechanically connect two metal pipes 11 to one another, metal holders 12 are provided. According to FIGS. 1 and 8 to 10, this metal holder 12 pass through the layer 15. Ver bund profiles with frame bars made of three metal tubes 11 can be constructed accordingly. The metal holder 12 can also be used to connect only the outer metal tubes 11 with coupling-free penetration of the middle metal tube.

Each metal holder 12 of FIGS. 1 to 9 is a solid metal pin, which must be coupled with a metal pipe 11 at its ends in a force-fitting and / or form-fitting manner. According to Fig. 1 of this metal tube 11 is provided for this purpose with a groove 13 which is cross-sectionally T-shaped. All wall elements of the metal tube 11 are of the same thickness. The wall 11 'is thus formed with the same wall thickness as the isoliermaterialsei term or the other metal tube 11 facing profile wall 14 and the groove 13 forming wall 11 '''. As a result of the T-shaped configuration of the groove 13 , this has an undercut that can serve to fix a head 18 of the metal holder 12 . The head 18 is formed with the same outer diameter as the metal holder 12 in its area within the layer 15th The head 18 fits through the slot 13 'and is inserted so far into the groove 13 that the neck 19 is exposed in the groove 13 . To hold the head 18 is a C-shaped coupling strip 16 vorhan which encloses the head 18 and fills the groove 13 in height. The coupling strip 16 engages around the head 18 in such a way that it cannot be pulled out of the groove 13 . There is therefore a positive connection between the metal holder 12 and the metal tube 11 .

The coupling bar 16 can according to FIG. 2, 3 may also be formed like plates flat. This coupling strip 16 also engages behind the head 18 of a metal holder 12 in the region of the neck 19 .

In order to be able to assemble the coupling strips of FIGS . 1 to 3 with the head 18 , in addition to a recess 20 having the neck diameter, a push-through opening 21 is present on each side and has a head diameter. To assemble a metal holder 12 with a metal tube 11 , the procedure is such that a coupling bar 16 is arranged in the groove 13 , the head passing through a push-through opening 21 when the metal tube 11 is pushed together with the metal holder 12 . Then the coupling bar 16 is moved relative to the metal tube 11 until the neck 19 is arranged in the recess 20 . It is understood that the neck 19 must be flattened accordingly between the recess 20 and the through-opening 21 , which was not shown in the drawing.

In order to securely connect the metal tubes 11 together over their entire length, a large number of coupling points 17 are required. In FIG. 2, only two of this multitude are shown, which are spaced 30 apart from one another due to the design. This distance can be changed as required, in which case only the coupling element 16 has to be changed accordingly, while the metal tubes 11 can be used unchanged. The metal holder 12 can NEN be attached to the groove 13 at any point. If necessary, the through holes 15 'of the layer 15 made of insulating material must be adapted accordingly.

The assembly of a composite section 10 of FIG. 1 can be mechanized in that metal tubes 11 lung afford with Kupp be compressed 16 in push-through position with layers 15 of insulating material transversely, said metal holder easily seated in the through-openings 15 'in a clamping 12 and are thus retained for assembly purposes . After reaching the assembly position shown in FIG. 1, the hitch be 16 strips together moved perpendicular to the plane of the illustration until the recess 20 engages around the neck 19 .

FIGS. 4, 5 show a coupling bar 16, which is flat, if provided with a through-opening 21 and a recess 20 this Benach disclosed. The recess 20 is matched in its width to the thickness of the neck 19 of the head 18 of the metal holder 12 . The recess 20 is designed in the manner of a slot and thus permits tolerance compensation between the coupling bar 16 and the position of a metal holder 12 in the longitudinal direction of the coupling bar 16 . So that the Stel development of the metal holder 12 is nevertheless secured, the coupling bar 16 has a tab 22nd This is cut out of the plate-like flat coupling bar 16 and angled so that it tends according to FIG. 5 below in its recess 20 covering area of the coupling bar 16 . As a result, it must be bent upwards when the head 18 is inserted, so that it then reaches the position shown in FIG. 5 above. The restoring forces of the tab 22 ensure that the head 18 is held firmly and cannot be easily moved relative to the coupling bar 16 .

FIGS. 6, 7 show a special flat plate-like coupling bar 16 with a recess 20, the overlapping of strips is limited 23rd These ledge tabs 23 form a flap ring which reduces the diameter of the recess 20 , the diameter adjustment being such that the diameter of the recess 20 is somewhat larger than the head of the metal holder 12 , but that the inner diameter formed by the flap ring of the flaps 23 is somewhat smaller , than the shaft diameter of the metal holder 12 , so that its head 18, which has a comparatively larger head diameter, can be engaged behind by the free ends of the tabs 23 . During assembly, the head 18 is inserted through the push-through opening 20 against the force of the tab 23 , the resilience of which leads that they reach behind the head 18 and support it against unwanted pulling out of the coupling element 16 .

The composite profiles of FIGS . 8 to 10 are similar in their basic structure to the composite profile of FIG. 9 and consequently comparable parts have been provided with the same reference characters and will not be described again below. The statements made above apply accordingly.

The composite profile 10 of FIG. 8 has metal tubes 11 with a different cross section of the groove 13 . The cross section is in the form of a segment of a circle and, accordingly, the wall section 11 '''of the metal tube 11 delimiting the groove 13 is also segmented in a circle. The metal holder 12 has a head which is partially spherical in example. The spherical configuration is given in the region of the groove 13 . In the area of the slot slot, a neck 19 connects to the shaft of the metal holder 12 . A slit-like notch 24 is provided in the head 18 , which divides it into two halves. As a result, the head 18 through the slot 13 'of the groove 13 ha can be pressed in a spring-like manner, so that it engages the undercut given by the cross-sectional shape of the groove 13 and corresponding pull-out forces ensure that an unwanted separation of the latching between the metal holder 12 and the metal tube 11 is not possible.

The metal holder 12 shown in Fig. 8 is cross-sectionally formed with a circle. However, it could also have rectangular cross sections, which would have the advantage that it could be cut from bar stock, which would reduce the manufacturing costs of the numerous metal holders 12 accordingly.

Fig. 9 shows the design of metal tubes 11 with grooves 13 rectangular cross-section. The groove bottom 28 is supported centrally via a metal web 29 on the outer wall 11 '' abge, this groove 13 is used to connect the metal tube 11 with the adjacent metal tube 11 via a square pin 26th In the area of its ends, the square pin is provided with clamping surfaces 25 , the distance between which is matched to the width of the groove 13 . The vote is in such a way fen that there is a sufficiently firm non-positive fit of the clamping surfaces 25 in the groove or between the groove walls. The clamping is produced by pressing in the metal holder 12 , the required stability of the wall areas forming the groove 13 being promoted by the metal web 29 .

Fig. 10 shows the configuration of a composite profile having no grooves. This means a corresponding freedom of movement in the cross-sectional design of the metal tubes 11 in the rest. The connecting elements only require a threaded bore 31 in order to secure the metal holder 12 . The metal holder 12 are designed as a tube or as a piece of pipe. They are attached to the metal tube 11 with cap screws 27 , to the head 27 'of which the metal holder 12 is coupled. The head screws 27 sit firmly in the threaded holes 31 , the latter z. B. can be produced by self-tapping head screw ben 27 . The head 27 'is provided with an undercut, so that the screw 27 can also be addressed as a clamping nipple screw. With the screw ben 27 , the metal holder 12 are positively coupled or locked. For locking, the hollow metal holder 12 have slot or diameter reductions 32 , which are produced, for example, by pressing from the end. As a result, the pipe sections in the direction of the screw axis can be pressed over the head 27 'and thus locked.

With all composite profiles, the coupling points 17 can be freely selected in order to prepare the composite profile for the individual load case. Composite profiles can also be equipped with metal brackets 12 , each of which cannot transmit comparatively high connecting forces. They will each be minimized in cross-section so that an unacceptable heat transfer from one side to the other can be excluded.
