Abstract

In order to be able to create a suitable swap body support frame (1) for virtually any desired longitudinal and transverse position as well as crashes of locking arms (3a, b) on the chassis (100) without damaging the factory corrosion protection coating of the commercial vehicle, it is proposed according to the invention to the attachment assembly (5) for connecting a locking arm (3a, b) with a side rail (100a, b) of the chassis (100) of a longitudinal plate unit (8) and a transverse plate unit (6) welded together, but preferably only after provisional attachment of these two units to the locking arm (3a, b) on the one hand and the longitudinal beam (100a, b) on the other hand takes place.With this provisional first attachment, the bores (8.1) for screwing only in the longitudinal plate unit (8) with the longitudinal member (100a, b) and in alignment with its bores (100.1) produced accurately. After welding in the provisionally mounted State, the mounting assembly (5) is removed again and can be individually and remotely from the vehicle subjected to the desired corrosion protection coating method such as hot-dip galvanizing.

Description

field of use

The invention relates to a so-called swap body support frame, as it is used on commercial vehicles, such as trucks and trailers, to attach and transport certain sizes of swap bodies.

II. Technical background

The cuboid swap bodies have at least in their lower corner areas twistlock openings through which so-called twistlocks, namely rotatable locking pin, can be inserted and locked in order to secure the swap body securely on a base, here a commercial vehicle.

Furthermore, swap bodies have on their underside on foldable support legs on which they can stand on the ground, so that a commercial vehicle drive underneath, saddle the swap body by raising its chassis by means of its air suspension, lock the twist locks, fold the support legs and the swap body then can carry away.

The swap bodies are available in different sizes and with different lengths of their support legs, and accordingly also have different longitudinal distances and possibly also transverse distances of their twistlock openings.

Likewise, the commercial vehicles manufacturers are equipped with differently shaped chassis, but usually two in the direction of travel, the longitudinal direction, side by side parallel side members have, however, depending on the manufacturer and vehicle model at different distances and with different heights of their upper edges.

To adapt a commercial vehicle to one or more sizes of swap bodies, the so-called swap body support frame is mounted as an adapter on the chassis, in particular the longitudinal members of the chassis of the commercial vehicle.

A swap body support frame consists on the one hand of a transversely extending, attached to the chassis of the commercial vehicle, extending transversely across both longitudinal beams locking arms whose length corresponds to the width of the interchangeable container to be supported, and at their ends on both ends at least one twistlock unit for locking the carry attached swap body against the locking arms.

• - Quertraversen, die in Querrichtung nur zwischen den beiden Längsträgern des Nutzfahrzeuges befestigt werden,
• - eine oder mehrere Mittenabstützung zur Abstützung der Wechselbehälter im mittleren Bereich von dessen Grundfläche,
• - Einweis-Rollen zum Führen des an der Unterseite des Wechselbehälters ausgebildeten so genannten Tunnels

usw.In addition, the swap body support frame usually also includes other items, such as

• - Crossbeams, which are attached in the transverse direction only between the two longitudinal members of the commercial vehicle,
• one or more center supports for supporting the swap bodies in the middle region of its base,
• - Guide rollers for guiding the so-called tunnel formed on the underside of the swap body

etc.

However, the most important in terms of stability most part are the most two locking arms, which must absorb most of the weight of the swap body and pass it to the chassis of the vehicle and must be secured accordingly load on the longitudinal members of the commercial vehicle.

The individual parts of a swap body support frame, in particular the locking arms are usually welded constructions, and were previously also attached by welding to the chassis of the commercial vehicle.

Since this, however, the manufacturer's existing coating of the chassis, which is indeed a corrosion protection coating, is damaged, and thus a corrosion protection warranty of the manufacturer is no longer true, for a long time swap body support frame only by screwing to the chassis of the Fastened commercial vehicle, and this used by the manufacturer, in particular already provided in the longitudinal members already numerous through holes.

This has the further advantage that the individual parts of the swap body support frame need not be corrosion-coated in the already welded on commercial vehicle condition, but much easier protected against corrosion before assembly, especially hot-dip galvanized, can be.

The disadvantage, however, is that a plurality of differently designed and dimensioned mounting assemblies must be made and / or kept in stock by the manufacturer of the swap body support frame in order to provide the locking arms on the side members of the chassis at the desired longitudinal position and in the desired height to attach.

To this end, each mounting assembly, which is usually an angled steel plate, has a transverse transverse plate portion for bolting to the transversely extending locking arm and a longitudinally extending longitudinal plate portion for longitudinal attachment thereto extending side members.

Although usually have the upright legs of the usually U-shaped longitudinal members already on the manufacturer a certain number of holes for screwing attachments, but this pattern of holes is usually different for each manufacturer and even for each vehicle type of a manufacturer.

Also, the locking arms have, usually in their side cheeks, a plurality of through holes in the region of their extension by being in the assembled state of the longitudinal beams thereunder in order to fasten a mounting assembly with respect to the position variable can.

As a rule, the swap body support frame is not mounted by its manufacturer on the chassis of the truck, but decentralized by contractors on site, so commercial vehicle outfitters or commercial vehicle Umrüstern that order the swap body support frame as a finished kit from the manufacturer and delivered and on Mount truck.

III. Presentation of the invention

Technical task

It is therefore the object of the invention to provide a modular system and a method for the manufacture of swap body support frame available, and in particular a finished swap body support frame, which reduces the number of required mounting assemblies.

Solution of the task

This object is solved by the features of claims 1, 10 and 17. Advantageous embodiments will be apparent from the dependent claims.

With regard to the method, this object is achieved in that the mounting assembly is not delivered as a finished item for mounting on the truck, and is not first mounted as a finished item for the first time on the truck.

• - einerseits eine Querplatten-Einheit, die die Querplatte zum Verschrauben am Verriegelung am umfasst und
• - andererseits einer Längsplatten-Einheit, die die Längsplatte zum Verschrauben am Längsträger des Chassis umfasst zur Montage angeliefert, wobei beide Einheiten in der Regel noch keine oder zumindest keine durchgehende Korrosionsschutz-Beschichtung aufweisen.

The mounting assembly is still in at least two separate items, namely

• - On the one hand, a transverse plate unit, which includes the transverse plate for screwing on the lock on and
• - On the other hand, a longitudinal plate unit, which comprises the longitudinal plate for screwing on the side member of the chassis for assembly supplied, both units usually have no or at least no continuous corrosion protection coating.

The mechanic, for example, the commercial vehicle outfitter, so on the one hand, the transverse plate unit on the locking arm and the longitudinal plate unit on the side member so positioning and screwing in this position, that the locking arm is in the desired longitudinal position, transverse position and height to the side rails of the chassis.

In this delivery state, the transverse plate of the transverse plate unit usually already has holes - with this term throughout the application always means through holes, which also need not necessarily be made by drilling - in such a size and arrangement, ie in one such hole pattern that these holes aligned by the mechanic aligned with holes on the locking arm and the transverse plate can be bolted to the locking arm, of course, in a region in the transverse direction, by extending below a side rail.

However, the longitudinal plate of the longitudinal plate unit for screwing to the side member has no holes.

The fitter attaches the longitudinal plates of the two longitudinal plate units initially only provisionally in a desired position on each of the side members, for example by jamming, in any case in such a way that he can then solve this provisional attachment again, without the corrosion protection coating of the longitudinal member was damaged thereby.

The desired position is that position which ensures that after fastening the locking arm by means of the attached thereto two transverse plate units on the two longitudinal plate units, the locking arm is at its desired position.

One possibility is that the fitter can position the longitudinal plates in the desired position on the basis of given installation dimensions with respect to the longitudinal member or with the aid of a supplied mounting template.

Another possibility is that it in a still displaceable state of the two longitudinal plates on the two side rails the locking arm, preferably with already attached transverse plate units, hangs on the two longitudinal plate units and on the one hand the two longitudinal plates to the two side rails and on the other the locking arm to the two longitudinal plate units so shifts until the locking arm has reached its desired position to the chassis exactly, and then fixed the longitudinal plates temporarily to the side rails.

Theoretically, the locking arm could initially also without cross-plate unit placed on the longitudinal plate units and only then the transverse plate units are bolted to the locking arm, but this is usually more complicated from the assembly process.

If the longitudinal plate unit consists of several parts as only the longitudinal plate, the other parts are preferably arranged before the provisional attachment of the longitudinal plate to this and preferably also attached, preferably already finally attached, such as welded. The same applies to the transverse plate unit.

• - stellt er mindestens zwei, meist mehrere Bohrungen in der Längsplatte her, die in diesem provisorisch montierten Zustand mit Bohrungen des Längsträgers, die von der Längsplatte abgedeckt sind, fluchten, vorzugsweise dadurch, dass er durch diese Bohrungen in dem Längsträger als Führung hindurch in die Längsplatte hinein bohrt und diese durchbohrt und
• - verschweißt er jede der Querplatten-Einheiten mit der jeweiligen, darunter befindlichen Längsplatten-Einheit in dieser provisorischen Anordnung zumindest so weit, dass diese beiden Einheiten pro Befestigungs-Baugruppe ihre Relativposition zueinander nicht mehr verändern können.

After the fitter has then again checked as a rule, that in this provisional arrangement of the parts of the locking arm is exactly at the intended target position,

• - He makes at least two, usually several holes in the longitudinal plate ago, which are aligned in this provisionally mounted state with holes in the longitudinal member, which are covered by the longitudinal plate, preferably in that it passes through these holes in the longitudinal member as a guide in the Drill longitudinal plate into and pierced and pierced
• - It welds each of the transverse plate units with the respective underlying longitudinal plate unit in this provisional arrangement at least so far that these two units per mounting assembly can not change their relative position to each other.

For this purpose, the two modules must not necessarily touch before, but in a sufficiently small, weldable, distance to each other. Because in most cases does not lie on the transverse plate or another part of the transverse plate unit on the longitudinal plate unit, but the locking arm itself is in the assembled state on the transverse plate unit.

Subsequently, the locking arm is again unscrewed and removed from the now preferably one-piece mounting assemblies on the one hand.

Then, after releasing the provisional attachment of the longitudinal plates of the respective mounting assembly from the side member, the mounting assembly can be removed from the side rail.

If the welding has been done so far only by a few welding points, now the welding of the transverse plate unit can be completed with the longitudinal plate unit.

Subsequently, the now, one-piece and finished welded, in particular all items comprehensive, mounting assembly coated with corrosion protection. Since the mounting assembly is no longer attached to the chassis, it can be moved freely, so for example be treated in a dip process, and / or brought to a galvanizing and hot-dip galvanized.

Subsequently, the now finished two mounting assemblies can in turn be positioned at the same position as before on the side rail, but now not longer provisionally but finally attached to it, but only by screwing through the aligned holes in the longitudinal plate on the one hand and the side member on the other ,

Finally, the locking arm is placed across the two mounting assemblies and bolted to their transverse plate units, in particular their transverse plates. This assembly is usually completed.

• - die zunächst ungelochte Längsplatte diese an sehr vielen verschiedenen Positionen vieler verschiedener Längsträger angeordnet und verschraubt werden kann
• - wegen der zunächst noch nicht gegeneinander fixierten Querplatten-Einheit und Längsplatten-Einheit viele verschiedene Querpositionierungen der Befestigungs-Baugruppe an dem Verriegelungsarm möglich sind und
• - die fertig gestellte Befestigungs-Baugruppe durch Beschichten nicht am Fahrzeug einem optimalen Beschichtung-Verfahren unterzogen werden kann.

The advantage of this approach is that

• - The initially unperforated longitudinal plate this can be arranged and screwed to a very many different positions of many different side members
• - Because of the initially not yet mutually fixed transverse plate unit and longitudinal plate unit many different lateral positioning of the mounting assembly to the locking arm are possible and
• - The finished mounting assembly by coating can not be subjected to the vehicle an optimal coating process.

With regard to the finished, especially finished mounted, swap body support frame, this object is thus achieved in that this pro Locking arm each comprises two mounting assemblies with which the same locking arm is bolted to each of the two side members, and usually two, sometimes more, such locking arms are present.

Each mounting assembly consists of a transverse plate unit and a longitudinal plate unit, which are welded together, wherein the transverse plate unit has a transverse plate with matching holes for screwing to the locking arm and the longitudinal plate unit has a longitudinal plate with matching holes for screwing to the Longitudinal member comprises.

Preferably, each longitudinal plate unit, in particular its longitudinal plate, in the upper edge of an upwardly open recess into which fits the transverse to the longitudinal plate extending locking arm and can be screwed in this position with the transverse plate unit.

The holes of the locking arm are preferably arranged in its vertical side cheeks, because the locking arm is usually a profile, such as a U-profile or a hat profile, or even consists of several such nested and welded together profiles.

In addition to the transverse plate, the transverse plate unit can also comprise, for example, spacing elements which protrude from the transverse plate transversely to its main plane under the locking arm resting thereon, in the region in which the locking arm rests on the longitudinal plate unit, in particular the longitudinal plate. rests to achieve the desired support height of the locking arm.

The run length can of course additionally and / or instead be realized by a corresponding height of the longitudinal plate, ie by the support surface of the longitudinal plate or the longitudinal plate unit for the locking arm against the holes for screwing to the longitudinal beam is correspondingly high.

In order to avoid bending the longitudinal plate, it is then useful to stiffen the longitudinal plate by one or more stiffening elements, which are preferably welded to the longitudinal plate.

Preferably, these are plate parts that are bracing away from the main plane of the longitudinal plate, and also curved plate parts, which can be present both on the side pointing toward the longitudinal carrier and on the opposite side of the longitudinal plate, which is usually screwed to the outside of the longitudinal carrier.

Such a stiffening element may have an upper, horizontally extending limb, the upper side of which can then be used as a bearing surface for the locking arm, that is, for example, rises somewhat higher upwards than the bottom of the recess in the longitudinal plate, but of course in the longitudinal region of the recess, in the direction how should be performed in front of the locking arm.

If the stiffening element strives towards the side toward the longitudinal member, the stiffening element may have a lower horizontally extending leg, the underside of which can be used for placement on the upper side of the longitudinal member so as not to have to absorb the entire forces only via the screw connection with respect to the longitudinal member.

These with their narrow sides on the longitudinal plate preferably attached and welded stiffening elements and / or spacer elements preferably have over its narrow side protruding one or more positioning projections that fit into the positioning recess in the longitudinal plate, which penetrate the longitudinal plate.

After insertion into the positioning recesses can be welded from the opposite side of the positioning projections relative to the peripheral edges of the positioning recess in a simple manner, for example, to obtain a first fixation before the remaining contact surfaces of the two parts circumferentially welded together become.

In this way, a swap body support frame can be made with little effort suitable for the particular application.

In particular, the stated object is achieved by a modular system for the production of interchangeable container support frame, which is preferably held by the manufacturer of the kits for swap body support frame:

Such a kit comprises on the one hand at least one variety, usually several varieties of locking arms that are ready for installation, that are coated with corrosion protection.

The kit also includes the items for producing different mounting assemblies in each case at least one, preferably in each case several varieties, namely both the transverse plate unit and the longitudinal plate unit.

If the transverse plate unit and / or the longitudinal plate unit comprises more than just the corresponding transverse plate or longitudinal plate, the kit can also those items, such as spacers or stiffening elements, in one or more varieties and in particular individually, so not in the with the respective transverse plates or longitudinal plates connected state.

As a result, the longitudinal plates or transverse plates contained in the kit can be used alone or supplemented by such items as spacers or stiffening elements.

The holes in the transverse plate are arranged overall in terms of size and positioning so that they can be aligned with holes in the locking arm, in particular its side cheeks, arranged and screwed against this. The holes are in the mounted state in the transverse direction in the area in which they are needed to be welded to a screwed to a longitudinal member longitudinal plate unit can.

The width of the recess measured in the direction of the main plane of the longitudinal plate is about 0.5 mm to 5 mm, more preferably 1.0 mm to 3 mm, greater than the measured in the same direction, viewed in the supervision width of the locking arm with it fixed cross plate unit. This difference is optimal in order to weld their transverse plate unit with the lateral edges of the recess of the longitudinal plate unit when inserted into the recess locking arm.

For on the one hand simple assembly and on the other hand sufficient positioning accuracy, it has proved to be advantageous that the centers of the holes in the transverse plate of the centers of the corresponding holes in the locking arm to a maximum of 3 mm, better at most 2 mm, better at most only 1 mm when these two components are placed together with optimally overlapping hole arrangement.

In contrast, it has proven to be useful to allow an analogous deviation between the center of the holes in the longitudinal plate to the corresponding holes in the side member by a maximum of 5 mm, better a maximum of only 3 mm, better at most only 2 mm.

Otherwise, the individual parts of the kit may have the details described in connection with the finished swap body support frame.

Embodiments according to the invention are described in more detail below by way of example. Show it:

• 1a a mounted on the two longitudinal members of a chassis swap body support frame with two locking arms in the plan,

• 1c : the swap body support frame 1a, b cut along the line C - C .

The 1a, b , c show the entire swap body support frame 1 mounted on the chassis 100 , namely bolted to the two parallel next to each other in the longitudinal direction 10 extending side members 100a . b - like the entire swap body support frame 1 in assembled condition - symmetrical to one both in longitudinal direction 10 so in the vertical 12 extending longitudinal center plane 10 ' is trained.

As 1c shows are the side members 100a . b each U-shaped seems that, with their open sides facing each other, so to the median longitudinal plane 10 ' indicative, are arranged.

In the transverse direction 11 runs at two different positions in the longitudinal direction 10 one locking arm each 3a . 3b over both side members 100a . b and stands across them in the transverse direction 11 outward, and is on the side rails 100a . b by means of a respective fastening assembly 5 screwed.

The locking arms 3a . b have such a length that the existing at their respective end twistlock units 2 with the upstanding and by means of an actuating lever 21 upward extendable twistlock 4 in the photographs, not shown on the swap body support frame 1 attached and thus to be locked containers 200 fit.

As 1b shows are the side members 100a . b already on the part of the commercial vehicle manufacturer in its upright leg of the U-profile with a variety of holes 100.1 equipped for attaching attachments and also in the present case for attaching the mounting assemblies 5 on the side rails 100a . b to be used.

• - einer Querplatten-Einheit 6, die zumindest zwei Querplatten 6a umfasst, die in Querrichtung 11 verlaufen und beidseits an je einer der beiden vertikal stehenden Seitenflächen eines Verriegelungsarmes 3a, b verschraubt sind im Bereich oberhalb eines der Längsträger 100 a, b und
• - einer Längsplatten-Einheit 8, die zumindest eine Längsplatte 8a umfasst, die etwa in Längsrichtung 10 verläuft und an der Außenseite des vertikalen Schenkels des Längsprofiles 100a, b anliegt und gegenüber diesem verschraubt ist, wobei die Querplatten-Einheit 6 und die Längsplatten-Einheit 8 im fertigen Zustand der Befestigungs-Baugruppe 5 miteinander verschweißt sind.

How best in the 1c right side as well as the detailed representations of the 2a to recognize c and 3a to c, there is each mounting assembly 5 - in each crossing area of a longitudinal member 100a . b with a locking arm 3a . b is present - off

• - a transverse plate unit 6 that have at least two transverse plates 6a includes, in the transverse direction 11 extend and on both sides of each one of the two vertical side surfaces of a locking arm 3a . b are screwed in the area above one of the side members 100 a, b and
• - A longitudinal plate unit 8th that has at least one longitudinal plate 8a includes, approximately in the longitudinal direction 10 runs and on the outside of the vertical leg of the longitudinal profile 100a . b is applied and bolted to this, the transverse plate unit 6 and the longitudinal plate unit 8th in the finished state of the mounting module 5 welded together.

As in 1a and better in the enlargement of the 2 B can be seen, the side members run 100a . b not necessarily over the entire length straight and exactly in the longitudinal direction 10 but in this case are in the longitudinal region in which the front locking arm 3a attached to it, easily S -developed, so that in the transition section of the side members 100a . b slightly oblique to the longitudinal direction 10 runs, and also the attached longitudinal plate 8a ,

The in the crossing areas of the locking arm 3a . b with the side rails 100 a . b each also marked leadership roles units 19 with the guide roller mounted thereon 19a are irrelevant to the present invention.

The 3a to c show a solution in which - as in 3b to recognize - the side member 100a also in the attachment area to the locking arm 3a straight and in the longitudinal direction 10 runs.

In 3a is contrary to 2a the locking arm 3a cut in front of the mounting assembly 5 shown and the guide roller unit 19 omitted for clarity, as well as in 3b ,

Furthermore, in 3a the longitudinal plate 8a in the not yet bolted state with the side member 100a shown, so that still the holes 8.1 in the longitudinal plate 8a to be seen, with the holes behind it 100.1 of the longitudinal member 100a aligned, leaving fastening screws 20 can be inserted through both.

• - die Längsplatten-Einheit 8 nur aus einer Längsplatte 8a besteht, die an der Außenseite des Längsträgers 100a verschraubt ist und
• - die Querplatten-Einheit 6 nur aus den beiden, vorzugsweise identischen, Querplatten 6a, die an den aufrechten Wangen des Verriegelungsarmes 3a, b außen angeschraubt sind.

The design of the 3a to c shows the simplest form of a mounting assembly 5 by using this solution

• - The longitudinal plate unit 8th only from a longitudinal plate 8a exists on the outside of the side member 100a is screwed and
• - the cross plate unit 6 only from the two, preferably identical, transverse plates 6a attached to the upright cheeks of the locking arm 3a . b screwed on the outside.

In 3a it can be seen that the longitudinal plate 8a in the upper area an upwardly open, U -shaped recess 9 has, on the bottom 9h the locking arm 3a with the lateral plates screwed to it 6a rests.

That's why the cross plates end 6a with its lower edge above the underside of the cross section of the locking arm 3a and with its upper edge below the top of the locking arm 3a ,

For improved load capacity, the recess 9 however, be arranged so that in the assembled state their ground 9a lower than the top of the upper horizontal leg of the longitudinal plate 8a carrying longitudinal member 100a . b so that the locking arm 3a directly on the side member 100 a, b rests and thus has a larger contact surface available.

The upright lateral edges of the U-shaped recess 9 are with the outer surfaces of the transverse plates 6a welded, like the in 3a drawn weld 22 suggests.

In this solution runs in the mounted state of the locking arm 3a ie directly over the side members 100a . b away or even on these, which is only a relatively low stability of the mounting assembly 5 especially against forces in the transverse direction 11 requires.

The design of the 2a to c differs from this - apart from the already mentioned in the attachment area oblique course of the side members 100a . b - especially in that the bottom of the locking arm 3a should be higher than the top of the side member 100a and also 100b , and for that purpose between the Top side of the upper horizontal leg of the longitudinal member 100a and the underside of the locking arm 3a in the crossing area spacer element 17 in the form of two superimposed plates are present as spacers and with the longitudinal plate 8a are preferably welded, preferably also welded against each other, which thus also part of the longitudinal plate unit 8th are.

The spacer elements 17 strive from the to the median longitudinal plane 10 ' directed inside the longitudinal plate 8a in the direction of the longitudinal center plane 10 ' starting at such a height that they are on top of the side member 100a rest, and in this state the longitudinal plate 8a with the side member 100a through through the two holes 8.1 and 100.1 inserted screws 20a and nuts screwed onto their free ends 20b are bolted.

The 4a to c show another design, in which the desired vertical distance between the locking arms 3a . b and the side members 100a . b should be even larger, so that only two superimposed steel plates as spacers 17 are no longer sufficient.

In this case, the now very high longitudinal plate 8a especially against lateral forces are stabilized, which by the both sides on the longitudinal plate 8a welded and projecting from the two main surfaces to the side stiffening elements 15 in the form of bent steel plates, which is also part of the longitudinal plate unit 8th are:

On the of the supporting side member 100a opposite outer side of the longitudinal plate 8a are two steel plates that are only cranked once 15 welded with their narrow sides so that their horizontally extending leg under the recess 9 protrudes, the top of this vertical leg, however, at the same height or preferably slightly higher than the ground 9a the recess 9 lies. As a result, these two legs serve as a support surface for the locking arm 3a ,

From this horizontal leg a vertical leg runs downwards for stabilization, and both are with the longitudinal plate 8a welded.

On the inside of the longitudinal plate 8a is a four times always bent in the same direction steel plate welded with its narrow sides at such a height that this almost closed rectangular profile with its underside on top of the side member 100a rests when the longitudinal plate 8a correct to the side member 100a is screwed.

As a result, the power is transmitted from the longitudinal plate unit 8th on the side member 100a or. 100b not just by the screw connection between these two parts.

Preferably, the tops, in this case the two free-ending and oppositely directed upper leg, extend this stiffening element 15 at height or just above the level of the ground 9a the recess 9 , and serve as in the case described above the 2a to c also as bearing surfaces for the locking arm 3a ,

To weld the stiffening elements 15 in the right position with the longitudinal plate 8a To facilitate, are at the stiffening elements 15 in the course of the longitudinal plate 8a to be welded narrow side several over the narrow side projecting positioning extensions 18 arranged, and in the longitudinal plate 8a matching positioning recesses at the right positions 16 , These are preferably made by means of laser cutting, as usually all steel plate parts of which the plates, the stiffening elements and the spacer elements consist.

For welding, the corresponding parts with the positioning projections 18 in the positioning recesses 16 inserted and due to this correct positioning, the parts can be welded against each other without further measures, if the size tolerance between the positioning recesses 16 and the positioning extensions 18 low enough is selected.
