Einbauten für z. B. Rieselkühler sind grundsätzlich bekannt und beispielsweise in DE-A-198 19 945, DE-A-197 33 480, US-B-6,241,222 und EP-A-0 825 407 beschrieben. Bei diesen bekannten Einbauten handelt es sich um Built-in for z. B. Trickle coolers are basically known and described for example in DE-A-198 19 945, DE-A-197 33 480, US-B-6,241,222 and EP-A-0 825 407. These known internals are
durchströmbare Einbauelemente zur Erhöhung der Oberfläche und Verweildauer des zu kühlenden Fluids in Rieselkühlern, wie beispielsweise Kühltürmen. Derartige Einbauten können auch zu Drainagezwecken im Erdreich oder in Chemie- bzw. biologischen Wasserbehandlungsanlagen eingesetzt werden. Die Einbauelemente (nachfolgend auch Einbauelementstapel genannt) weisen eine Vielzahl aneinanderliegende gewellte Kunststofffolien oder -gittermatten auf, zwischen denen sich kreuzende Kanäle bilden . Bei Kühltürmen werden mehrere Lagen nebeneinander angeordneter Einbauelemente eingesetzt, wobei die Einbauelemente der untersten Lage auf Abstandsblöcken ruhen. Dabei sind die einzelnen Einbauelemente an ihren einander gegenüberliegenden Enden durch jeweils einen Abstandsblock gestützt. Die Montage dieser Abstandsblöcke ist recht aufwendig . In DE-B-10 2005 010 462 ist eine Vorrichtung zum Verschweißen mehrerer Einbauelementstapel beschrieben . flow-through installation elements to increase the surface and residence time of the fluid to be cooled in trickle coolers, such as cooling towers. Such internals can also be used for drainage purposes in the ground or in chemical or biological water treatment plants. The built-in elements (hereinafter also referred to as built-in element stack) have a multiplicity of adjoining corrugated plastic films or lattice mats, between which intersecting channels are formed. In cooling towers several layers of juxtaposed mounting elements are used, the mounting elements of the lowest layer resting on spacer blocks. The individual mounting elements are supported at their opposite ends by a respective spacer block. The installation of these spacer blocks is quite expensive. In DE-B-10 2005 010 462 a device for welding a plurality of built-in element stack is described.
Eine Aufgabe der Erfindung ist es daher, die Verschweißung benachbart an- geordneter Einbauelementstapel zu verbessern . It is therefore an object of the invention to improve the welding of adjoining stack of built-in elements.
Zur Lösung d ieser Aufgabe werden mit der Erfindung eine Vorrichtung zum Verschweißen benachbarter Einbauelemente für Vorrichtungen zur Behand lung eines Nutzfl uids mittels eines Arbeitsfluids vorgeschlagen, wobei jedes Einbau- element benachbart zueinander angeordnete Kunststoff platten aufweist, zwischen denen Kanäle ausgebildet sind , wobei d ie Vorrichtung zum Verschweißen versehen ist mit To solve this object, the invention proposes a device for welding adjacent installation elements for devices for treating a useful fluid by means of a working fluid, each mounting element having adjacently arranged plastic plates, between which channels are formed, the device is provided with for welding
einer Heizeinheit zum Erweichen mindestens eines Einbauelements an dessen mit einem anderen Einbauelement zu verbindenden Seite und - einer And rückeinheit zum Gegeneinanderd rücken der an ihren zu verbindenden Seiten aneinanderliegenden Einbauelemente,  a heating unit for softening at least one installation element at its side to be connected to another installation element, and a support unit for pushing against one another the installation elements lying adjacent to one another at their sides to be connected,
wobei die Heizeinheit mindestens eines Einbauelements an dessen mit einem anderen Einbauelement zu verbindenden Seite aufweist. Nach der Erfindung wird also vorgeschlagen, benachbarte Einbauelemente un¬ tereinander d urch Verschweißen zu verbinden, wobei d ie Erweichung zumindest einer der Seiten zweier miteinander zu verschweißenden Einbauelemente berührungslos erfolgt. Jedes Einbauelement besteht aus einer Vielzahl von aneinanderl iegenden gewel lten Kunststofffolien oder -g ittermatten (oben und nachfolgend mit " Kunststoffplatte" bezeichnet), deren Außenränder die Außenseiten der Einbauelemente definieren . Zwei benachbarte Einbauelemente sind nun erfindungsgemäß an ihren aneinanderl iegenden Außenseiten miteinander verschweißt. Mit anderen Worten sind also benachbarte Einbauelemente an den einander zugewandten Rändern ihrer Kunststofffolien bzw. Gittermatten miteinander verschweißt. Die Erhitzung der Einbauelemente zum Verschweißen erfolgt dabei berührungslos mittels elektromag netischer Strahl ungswärme, wie z. B. Laser- oder IR-Strahl ung bis zur Erweichung des Materials des Einbau- elements an dessen Oberflächen bzw. in dessen oberflächennahen Bereichen erfolgen. Dabei kann zumindest einem der jeweils zwei zu verschweißenden Einbauelemente an/in dessen zu verschweißender Seite ein Zuschlagsstoff zur Absorption der Strahlungsenergie zwecks (örtlicher) Erhitzung dieser Seite zu- gegeben sein. Derartige Zuschlagsstoffe (Stoffe mit Strahlungsabsorptionsko- effizienten für die Kunststoffverschweißung) sind an sich bekannt. wherein the heating unit has at least one installation element on its side to be connected to another installation element. According to the invention it is therefore proposed to join adjacent mounting elements behind the other un ¬ d urch welding, wherein t he softening at least one of the sides of two to one another is to be welded mounting elements without contact. Each paving element consists of a plurality of contiguous corrugated plastic sheets or liner mats (referred to above and below as "plastic sheet") whose outer edges define the outsides of the paving elements. Two adjacent installation elements are now welded together according to the invention at their contiguous outer sides. In other words, therefore, adjacent mounting elements are welded together at the mutually facing edges of their plastic films or mesh mats. The heating of the installation elements for welding takes place without contact by means of electromag netic radiation radiation, such. B. Laser or IR radiation until softening of the material of the installation elements take place on its surfaces or in its near-surface areas. In this case, at least one of the two respective mounting elements to be welded on / in its side to be welded may be given an additive for absorbing the radiant energy for the purpose of (local) heating of this side. Such additives (substances with Strahlungsabsorptionsko- efficient for plastic welding) are known per se.
Durch die Verbindung benachbarter Einbauelemente wird der Montageaufwand für die unterste Einbauelementlage insofern vereinfacht, als nun für benach- barte Einbauelemente lediglich nur noch ein Abstandsblock bzw. eine Reihe von Abstandsblöcken verwendet und die Stützfläche pro Einbauelement reduziert werden kann. Auf diesem Abstandsblock bzw. dieser Reihe von Abstandsblöcken ruhen die benachbarten Einbauelemente gemeinsam. Der Abstandsblock bzw. die Reihe von Abstandsblöcken ist dabei vorzugsweise mittenzen- triert zur durch die aneinanderliegenden Anlageseiten benachbarter Einbauelemente definierten Vertikalebenen angeordnet. The connection of adjacent installation elements simplifies the installation effort for the lowermost installation element layer insofar as now only one spacer block or a series of spacer blocks is used for adjacent installation elements and the support surface per installation element can be reduced. On this spacer block or this series of spacer blocks rest the adjacent mounting elements together. The spacer block or the row of spacer blocks is preferably center-trated to the vertical planes defined by the adjoining installation sides of adjacent installation elements.
Ferner wird der Einbauelementlage durch die Verbindung benachbarter Einbauelemente auch eine erhöhte Stabilität verliehen, da benachbarte Einbau- elemente nun nicht mehr gegeneinander bewegbar sind. Somit kann auch Material bei der Herstellung der Blöcke verringert werden, da eine höhere Festigkeit mit geringerem Eigengewicht erreicht werden kann. Furthermore, the installation element layer is also given increased stability by the connection of adjacent installation elements, since adjacent installation elements are no longer movable relative to one another. Thus, material can be reduced in the production of the blocks, since a higher strength can be achieved with a lower dead weight.
Die verlängerten Blöcke erlauben eine kosteneffektive Produktion, da durch die Endlosproduktion die gewünschten Blocklängen abgeschnitten werden und somit keine Rest-Abfa II blocke entstehen. Zudem kann bei dem Ersetzen von alten Blöcken in einem Kühlturm die vorhandene Unterstützungskonstruktion beibehalten werden, was eine deutliche Einsparung an Kosten ausmacht. Die erfindungsgemäße Vorrichtung weist eine kontaktlos arbeitende Heizeinheit auf, durch die zeitgleich die Seiten zweier benachbarter zu verbindender Einbauelemente erweicht werden. Durch die Andrückeinheit werden die beiden Einbauelemente anschließend gegeneinander gedrückt, bis die erweichten einander zugewandten Ränder der Kunststoff platten (Gitter- oder Folienplatten) der beiden zu verbindenden Einbauelemente wieder abgekühlt und damit stoffschlüssig verbunden sind. Bevorzugt wird eine Laser- oder IR-Heizquelle ein- gesetzt. The extended blocks allow a cost-effective production, since the desired block lengths are cut off by the endless production and thus no residual Abfa II blocke arise. In addition, replacing old blocks in a cooling tower can preserve the existing support structure, resulting in a significant cost savings. The device according to the invention has a contactless heating unit by which the sides of two adjacent installation elements to be connected are softened at the same time. By the pressure unit are the two Built-in elements then pressed against each other until the softened facing edges of the plastic plates (grid or foil plates) of the two to be connected mounting elements cooled again and thus are materially connected. Preferably, a laser or IR heat source is used.
Vorteilhafterweise weist die Heizeinheit ein plattenförmiges Heizelement mit zwei einander abgewandten Heizseiten auf, mit denen zwei zu verbindende Einbauelemente zwecks Erweichung ihrer zu verbindenden Seiten in Kontakt bringbar sind. Advantageously, the heating unit has a plate-shaped heating element with two heating sides facing away from one another, with which two installation elements to be connected can be brought into contact for the purpose of softening their sides to be joined.
Zur weiteren Automatisierung der Herstellung verschweißter Einbauelemente für Rieselkühler ist gemäß einer Weiterbildung der Erfindung eine Transporteinheit zum Transportieren eines Einbauelements zu einem mit diesem zu ver- bindenden Einbauelement vorgesehen, wobei es sich bei der Transporteinheit beispielsweise um ein Förderband oder dergleichen Rollen- oder Laufband handelt. Das Heizelement der Heizeinheit ist vor dem Gegeneinanderdrücken der zu verbindenden Einbauelemente in den Zwischenraum zwischen den zu verbindenden Seiten der mittels der Transporteinheit nah zueinander angeord- neten Einbauelemente eintauchbar. In dieser Phase sind die zu verbindenden Einbauelemente in Kontakt mit den einander gegenüberliegenden Seiten des Heizelements bringbar. Anschließend fährt das Heizelement aus dem Zwischenraum zwischen den beiden Einbauelementen heraus, woraufhin die beiden Einbauelemente gegeneinander gedrückt werden. Die Andrückeinheit weist dabei vorteilhafterweise ein Arretier-/Blockierelement zum Blockieren des einen der zu verbindenden Einbauelemente sowie ein Andrückelement zum Andrücken des anderen der zu verbindenden Einbauelemente gegen das blockierte Einbauelement auf. Als Andrückelement kann dabei beispielsweise ein das Einbauelement transportierendes Bewegungselement der Transporteinheit, beispielsweise eine Transportrolle, ein Transportband oder eine verfahrbare Greifereinheit sein. Bevorzugt erfolgt die Verschweißung mittels Infrarot-(IR-)Lichtschweißen des grundsätzlich thermoplastischen Materials der Einbauelemente. Hier bedarf es eines automatisch oder manuell geführten IR-Strahlers, mit dem vornehmlich die gesamten zu verschweißenden Flächen zweier zu verbindenden Einbauelemente, mindestens aber so große Flächenbereiche erweicht werden können, dass nach anschließendem Fügen der Einbauelemente und Abkühlen der erweichten Flächenbereiche ein für die jeweilige Anforderung an die Stabilität der Verbindung flächenmäßig ausreichend großer Stoffschluss entsteht. Grundsätzlich ist es aber ausreichend, wenn lediglich eine der beiden zu verschweißenden Flächen bzw. Seiten der Einbauelemente erweicht/erhitzt ist. In order to further automate the production of welded installation elements for trickle coolers, according to a development of the invention, a transport unit is provided for transporting a mounting element to a mounting element to be connected thereto, wherein the transport unit is, for example, a conveyor belt or similar roller or treadmill. The heating element of the heating unit can be immersed in the intermediate space between the sides to be joined of the installation elements which are arranged close to one another by means of the transport unit, before the mounting elements to be joined are pressed against one another. In this phase, the mounting elements to be connected in contact with the opposite sides of the heating element can be brought. Subsequently, the heating element moves out of the intermediate space between the two mounting elements, whereupon the two mounting elements are pressed against each other. The pressing unit advantageously has a locking / blocking element for blocking one of the installation elements to be connected and a pressing element for pressing the other of the installation elements to be connected against the blocked installation element. In this case, the pressing element can be, for example, a movement element of the transport unit transporting the installation element, for example a transport roller, a conveyor belt or a movable gripper unit. Preferably, the welding takes place by means of infrared (IR) light welding of the basically thermoplastic material of the mounting elements. This requires an automatically or manually guided IR radiator, with which primarily the entire surfaces to be welded two installation elements to be joined, but at least so large surface areas can be softened that after subsequent joining of the mounting elements and cooling the softened surface areas for the respective requirement on the stability of the compound areally sufficiently large material bond arises. In principle, however, it is sufficient if only one of the two surfaces or sides of the installation elements to be welded is softened / heated.
Die Verwendung einer Schweißtechnik durch ein oder mehrere Strahlungsheizquellen hat den Vorteil, dass es keinerlei Kontakt der Einbauelemente mit temperierten bzw. heißen Elementen bedarf, die Erweichung des Materials also berührungslos erfolgt, womit auch keinerlei (Schweiß-)Elemente o.dgl. verunreinigt werden können. The use of a welding technique by one or more Strahlungsheizquellen has the advantage that it requires no contact of the mounting elements with tempered or hot elements, the softening of the material thus takes place without contact, which also no (welding) elements or the like. can be contaminated.

Fig . 1 zeigt den grundsätzlichen Aufbau eines Kühlturms 10 mit darin angeordneten Einbauelementen 12 als ein Anwendungsbeispiel für diese Elemente. Die Einbauelemente 12 sind in mehreren Lagen übereinander angeordnet, wobei die Einbauelemente 12 der untersten Lage auf Abstandsblöcken 14 ruhen. Das zu kühlende Fl uid (in diesem Fal l Wasser) gelangt über eine Verteilerleitung 16 oberhal b der obersten Lage von Einbauelementen 12 in den Kühlturm 10 hinein, wo es über Düsen 18 versprüht wird . Das versprühte zu kühlende Fluid "rieselt" an den in d iesem Ausführungsbeispiel d reidimensional Fig. 1 shows the basic construction of a cooling tower 10 with built-in elements 12 arranged therein as an example of application for these elements. The mounting elements 12 are arranged one above the other in a plurality of layers, with the mounting elements 12 of the lowermost layer resting on spacer blocks 14. The To be cooled Fl uid (in this case l water) passes through a manifold 16 oberhal b the uppermost layer of mounting elements 12 into the cooling tower 10 into where it is sprayed through nozzles 18. The sprayed fluid to be cooled "trickles" to the in this embodiment d three-dimensionally
durchströmbaren Einbauelementen 12 entlang und kommt ferner in Kontakt mit der Kühll uftströmung , die aufgrund der durch den Aufbau des Kühlturms 10 erzeugten Kaminwirkung d urch d iesen hindurchströmt. U nterhalb des Kühlturms 10 befindet sich von diesem beabstandet ein Sumpf 20, aus dem das abgekühlte Fl uid abgeführt und dem Prozess wieder zugeführt wird . flow through the installation elements 12 along and also comes in contact with the cooling air flow, which flows through d iesen due to the chimney effect generated by the structure of the cooling tower 10 therethrough. U nter the cooling tower 10 is spaced from this a sump 20, from which the cooled Fl uid is discharged and fed back to the process.
Wie bereits zuvor erwähnt, sind die Einbauelemente 12 zumindest eind imensional durchströmbar. Derartige Einbauelemente 12 weisen eine Vielzahl von gewel lten und zueinander versetzt angeord neten Kunststofffolien- oder -gitter auf, zwischen denen sich einzel ne Kanäle bilden . An den Innenwand ungen die- ser Kanäle läuft das zu kühlende Fluid entlang . Bei jedem dieser Einbauele¬ mente 12 handelt es sich also um einen Stapel von über- oder nebeneinander angeord neten Kunststoff matten, d ie miteinander mechanisch verbunden sind, was an sich bekannt ist. Zweckmäßig ist es allerdings, wenn d ie Einbauelemente 12 aus einzel nen git- terförmigen Kunststofffolien (z. B. Gittermatten) bestehen, d ie ebenfal ls gewel lt sind . Auch hier werden mehrere derartige Gittermatten versetzt, verd reht oder dergleichen zueinander aneinanderl iegend zu Stapel n zusammengefasst, die die Einbauelemente bilden . In sämtl ichen Fällen sind die Einbauelemente 12 "stehend " im Kühlturm 10 angeordnet; d ie Kunststofffolien bzw. Gittermatten verlaufen dabei also nicht horizontal , sondern vertikal . As already mentioned above, the installation elements 12 can be flowed through at least one dimensionally. Such mounting elements 12 have a multiplicity of corrugated and mutually offset angeord Neten plastic film or grid, between which form individual ne channels. The fluid to be cooled runs along the inner wall of these channels. Each of these Einbele ¬ elements 12 is thus a stack of over or next to each other angeord Neten plastic mats, ie he mechanically connected to each other, which is known per se. However, it is expedient if the built-in elements 12 consist of individual grid-shaped plastic films (eg grid mats) which have also been wound. Again, a plurality of such grid mats are offset, twisted or the like to each other together to stack n summarized n, which form the mounting elements. In sämtl IEN cases, the mounting elements 12 "standing" in the cooling tower 10 are arranged; The plastic films or grid mats do not run horizontally, but vertically.
Wie ebenfal ls oben erwähnt, ruht die unterste Lage von Einbauelementen 12 im Regelfal l auf Abstandsblöcken 14. Zur M inimierung des Aufwandes der Mon- tage und der Anzahl dieser Abstandsblöcke 14 ist bei der Erfind ung vorge¬ sehen, benachbarte Einbauelemente 12 zumindest der untersten Einbaulage untereinander an ihren Anlageseiten 22 zu verschweißen . Die Schweißebene 24 ist in Fig . 1 bei 24 angeordnet. How also proposes ls mentioned above, rests the lowermost layer of built-in elements 12 in Regelfal l on spacer blocks 14 days to M inimierung the expense of Mon and the number of these spacer blocks 14 is laid ¬ seen at the erfind ung, adjacent packing elements 12, at least the lowermost Mounting position to be welded together at their plant sides 22. The welding plane 24 is shown in FIG. 1 at 24 arranged.
Ein Ausführungsbeispiel einer automatisch arbeitenden Vorrichtung 26 zum Verschweißen benachbarter Einbauelemente 12 ist in unterschiedl ichen Phasen ihres Arbeitsablaufs in den Fign . 2 bis 7 gezeigt. Die Vorrichtung 26 weist eine Transporteinheit 28 auf, die in d iesem Ausführungsbeispiel zwei sich aneinander anschl ießende Endlos-Transportbänder 30, 32 aufweist. Etwa in Höhe der einander zugewandten Enden dieser beiden Endlos-Transportbänder 30, 32 befindet sich eine Heizeinheit 34. Die Heizeinheit 34 weist einen Halter 36 mit einander abgewandt ausgerichteten (z. B. Laser- oder IR-)Strahl ungsheizquel- len 38 auf und ist in Richtung auf d ie Transporteinheit 28 vor und in entgegengesetzter Richtung von dieser wieder weg bewegbar. Ferner ist die Vorrichtung 26 mit einem Arretierelement 40 und einem And rückelement 42 einer And rü- ckeinheit 44 versehen . An embodiment of an automatically operating device 26 for welding adjacent mounting elements 12 is shown in different phases of their working sequence in FIGS. 2 to 7 shown. The device 26 has a transport unit 28, which in this exemplary embodiment has two endless conveyor belts 30, 32 adjoining each other. A heating unit 34 is located approximately at the level of the mutually facing ends of these two endless conveyor belts 30, 32. The heating unit 34 has a holder 36 with radiation heating sources 38 (FIG is in the direction of the transport unit 28 before and in the opposite direction away from this again movable. Furthermore, the device 26 is provided with a locking element 40 and a back element 42 of a back unit 44.
Der Beweg ungsablauf der Vorrichtung 26 ist wie folgt. The movement of the device 26 is as follows.
Ausgangspunkt ist die Situation gemäß Fig . 2, in der auf beiden Endlos-Trans- portbändern 30, 32 jeweils ein Einbauelement 12 ruht. Diese beiden Einbauelemente 12 sind auf Abstand zueinander angeord net, so dass zwischen d ie beiden einander gegenüberliegenden Anlageseiten 22 der beiden Einbauelemente 12 die Heizeinheit 34 eintauchbar ist. Nu n werden die beiden Einbauelemente 12 an ihren späteren, einander gegenüberl iegenden Anlageseiten 22 kontaktlos erhitzt. Nach dem Erweichen der beiden Einbauelemente 12 an ihren einander zugewandten Anlageseiten 22 fährt die Heizeinheit 34 aus dem Bereich zwischen den beiden Einbauelementen 12 wieder heraus, woraufhin die beiden Einbauelemente 12 in Kontakt miteinander gebracht werden . Dies erfolgt beispielsweise d urch eine entsprechende Ansteuerung des in Fig . 4 l in- ken Endlostransportbandes 30, bis das l inke Einbauelement 12 an dem rechten Einbauelement 12 anliegt. Zum Andrücken der beiden Einbauelemente 12 dient das Arretierelement 40, das das in Fig . 4 rechts eingezeichnete Einbauelement 12 blockiert, während das Andrückelement 42 das in Fig . 4 l inks dargestel lte Einbauelement 12 gegen das von dem Arretierelement 40 blockierte rechte Einbauelement 12 drückt. In dieser Phase erfolgt die Verschweißung der beiden Einbauelemente 12 an deren einander zugewandten Anlagenseiten 22, wodurch sich die The starting point is the situation according to FIG. 2, in which a respective mounting element 12 rests on both endless conveyor belts 30, 32. These two mounting elements 12 are at a distance angeord net, so that between the two opposing plant sides 22 of the two mounting elements 12, the heating unit 34 is submerged. Nu n the two mounting elements 12 are heated contactless at their later, gegenüberl opposing plant sides 22. After softening of the two mounting elements 12 at their mutually facing contact sides 22, the heating unit 34 moves out of the area between the two mounting elements 12 again, whereupon the two mounting elements 12 are brought into contact with each other. This is done, for example, by a corresponding activation of the device shown in FIG. 4 l ken Endlostransportbandes 30 until the inline mounting element 12 rests against the right mounting element 12. For pressing the two mounting elements 12, the locking element 40, which serves as shown in FIG. 4 right plotted installation element 12 is blocked, while the pressing member 42, the in Fig. 4 l inks dargestel Lte installation element 12 against the blocked by the locking element 40 right mounting element 12 presses. In this phase, the welding of the two mounting elements 12 takes place at their mutually facing plant sides 22, whereby the
Schweißebene 24 bildet. Weld level 24 forms.
Anschließend werden d ie beiden verschweißten Einbauelemente 12 durch ent- sprechende Ansteuerung des Endlostransportbandes 32 bezogen auf d ie Dar¬ stell ung in den Fig n . nach rechts verfahren (siehe Fig . 5) und ein neues Einbauelement 12 wird auf das Transportband 30 gebracht bzw. von dem Trans¬ portband 30 bis in Höhe der Heizeinheit 34 transportiert. Anschließend fährt die Heizeinheit 34 in den Zwischenraum zwischen dem weiteren zu ver- schweißenden Einbauelement 12 und dem bezogen auf d ie Zeichnung in Fig . 5 linken Einbauelement 12 der beiden rechts dargestellten miteinander verschweißten Einbauelemente 12. Der oben besch riebene Prozess setzt sich nun entsprechend fort (siehe d ie Fig n . 6 und 7), so dass am Ende d ieser zweiten Phase nunmehr d rei benachbarte Einbauelemente 12 miteinander verschweißt sind . Then, t he two welded mounting elements 12 are related by corresponding driving the endless conveyor belt 32 on t he Dar ¬ alternate ung n in Figs. move to the right (see Fig. 5) and a new mounting element 12 is placed on the conveyor belt 30 and transported by the trans ¬ porting tape 30 up to the height of the heating unit 34. Thereafter, the heating unit 34 moves into the interspace between the further installation element 12 to be welded and the base element, which is based on the drawing in FIG. The process described above proceeds accordingly (see FIGS. 6 and 7), so that at the end of this second phase, there are now two adjacent built-in elements 12 with each other are welded.
Entsprechend wird verfahren, um die gewünschte Anzahl von benachbarten Einbauelementen 12 zu verschweißen . Die Vorrichtung 26 kann noch mit einer (nicht dargestel lten) Schneidvorrichtung versehen sein, um die am Ende einer Reihe von Einbauelementen 12 befindl ichen Einbauelemente der Kontur des Kühlturms 10 oder dem Bauraum, in dem sie unterzubringen sind, entsprechend abzuschneiden . Accordingly, the procedure is to weld the desired number of adjacent mounting elements 12. The device 26 may still be provided with a (not illustrated) cutting device to correspondingly cut off the installation elements located at the end of a series of installation elements 12 of the contour of the cooling tower 10 or the installation space in which they are to be accommodated.
