Description

"Eabelbahnw

Addition to patent application P 28 29 905.0-34 The invention relates a cable track made of sheet metal, in particular sheet steel, consisting of im Cross-section of approximately U-shaped channel sections.

So far, such cable duct sections are each made in one piece, such that edge parts forming spars are bent on a sheet metal blank.

However, around a cableway that can be assembled from such sections adapt to the respective requirements in terms of capacity and / or load-bearing capacity However, to be able to do so, it is necessary to have a plurality of them different from one another to manufacture and lågern dimensioned cable duct sections.

The invention is based on the object with the simplest means to reduce the number of types of Eabelbahn sections and significantly reduce storage to simplify.

The solution to this problem is characterized in that each channel section from two L-shaped profiled support bars and from a prefabricated, between arranged on the spars and assembled on the bottom held on the latter is.

It is particularly advantageous if the floor has a lower Has sheet thickness than the support bars.

This has the advantage that a floor spars with high BEZW. less Load capacity can be assigned.

In addition, it is possible to use a narrow or a pair of spars assign a wide base, so that now with relatively little prefabricated Individual parts a multitude of mutually different cable duct section types can be formed.

In addition, the arrangement of relatively thin floors with less Material expenditure than previously achieved high load-bearing capacities.

Furthermore, there is the advantage that now the cableway sections can only be assembled at the place of use, resulting in a considerable reduction the freight volume and the amount of packaging material required.

An advantageous and inventive development of the above The subject is that across the ground. extending to its longitudinal extent and spaced stiffening beads protruding into the cableway channel are formed, preferably also the stiffening beads on the longitudinal edges the bottom are formed opening out.

It should be true even in the case of cable duct sections produced in one piece It may be possible to provide stiffening beads in the floor, with the latter before or after to the Folding of sheet metal edge parts to form the spars can be, only then there would be the disadvantage that the beads only by elongation of the sheet with a simultaneous significant reduction in sheet thickness in the area the beads can be produced, while the cable duct section according to the invention the beads formed on the floor retain the original sheet metal thickness and thus with the same profiling a significantly higher flexural strength than with the previously described, fictitious design.

In addition, it is excluded in the subject matter of the invention that the formation of transverse to the longitudinal extension of the cable duct sections Stiffening beads to change the shape of the bars or to stress peaks in the bars which certainly increases the load-bearing capacity of the spars and thus of the entire Eabelkanal section reduce.

Another feature that promotes production is that that the stiffening beads have the same cross-sections over their entire length.

In addition, is an advantageous feature of the subject matter described above characterized in that in the ground, namely in the between the stiffening beads Ventilation holes are located in the floor zones.

This results in cooling by air convection in the cable duct laid and anyway only supported on the stiffening beads cables Significantly improved without affecting the dimensional stability of the Eabel canal.

The bars and the floor can be welded to one another get connected.

A connection to be carried out with simpler tools is thereby characterized in that each opposite one another in the spars and in the ground Breakthroughs for receiving positively effective connecting elements, in particular Rivets are arranged.

The spars and the floor are preferably used as connecting means Penetrable nails are provided, which are shot in without the one another the parts to be connected must be punched beforehand.

With the connection options described above, it is advantageous to when one leg of both spars is directed inwards and parallel to the ground are arranged to run and that the connecting means the inward straightened spars legs and the edge parts of the latter which can be supported Penetrate the soil.

A particularly advantageous connection option between the floor and the spars is that cut on the inwardly directed spar legs and arranged from the original plane towards the ground bow-shaped webs are, furthermore, the bottom of the base surface of the bow-shaped webs adapted openings has, through each of which a bow-shaped web engages in a form-fitting manner, and that for each web at least one gripping under it and supporting itself on the ground, at least secured by static friction, the floor on the inward facing Spar legs pressing pin is arranged.

It is advantageous if the webs each extend longitudinally the spars and, accordingly, the pins running transversely to the longitudinal extension of the spars are directed, and preferably also in the lateral, protruding the rungs Spar legs provided the bow-shaped webs opposite pin through openings are.

In this way, cableway sections, their spars and floors are obtained at the destination simply by means of a plug connection without any aids Can be connected to each other in the correct position and with the means for securing the plug connections, namely the pins driven in with the simplest of striking tools can be, wherein the through openings continue the arrangement of the pins make it much easier.

In order to have a positive fit even with relatively coarse manufacturing tolerances as well as to ensure a positive connection between the bars and the floor, Characterizes an advantageous design of a previously described detail by wedge-shaped, in particular conical pins.

A variant which may be preferred under certain circumstances is that and having at least approximately the same cross-sections over their entire length pointed at the free end part and at least the bow-shaped webs when driving in elastically elongated pins are provided.

Such pins can optionally be made from wire sections at the destination to replace lost pins. It is also ensured that that when driving in the pins of these influences the ground positively the inwardly directed spar legs are pressed.

In order to prevent accidental loosening of the pins, it is advantageous to if the pins each have a laterally protruding, approximately in the middle of their lengthwise insertion, especially cranked and located in the web under the cut stile Have breakthrough positively snap-in zones.

A variant that may be preferred under certain circumstances is identified for this in that the pins each have at least one constriction and that on the bow-shaped webs protruding towards the pins and into the pin constrictions snap-in projections are arranged.

Furthermore, an advantageous design of the above is characterized Object by having heads, as well as with the heads in corresponding depressions embedded in the spars and at most flush with the sides of the spar walls Pencils.

As a result, the pins cannot be driven in beyond their closed position will.

In addition, a misalignment of the pins is obvious.

The cableway can also be alongside a wall and close to it arrange close to each other.

To avoid damage to the cables from the sharp-edged bead end parts of the soil are excluded in the lateral stile legs at a distance above the inwardly directed spar legs, inwardly depressed and protruding over the more or less rounded corner corners arranged beads provided. In addition, the bottom beads are with their front sides arranged lying on the sides of the spar beads facing them.

This also results in an increase in the dimensional stability of the entire Cableway.

A design that facilitates the manufacture of the pin-Eopf recess is that the head of the pins receiving recesses in the lateral Spar legs are designed as longitudinal beads.

Further advantageous features for the correct and secure position Connection of the spars to the floor are disclosed in claims 21-25.

Embodiments of the invention are shown in the drawings and are described in more detail below.

1 shows a perspective illustration of an egg-shaped web section, Fig. 3 to 5 further profile shapes, Fig. 2 variants of further details in perspective representation.

The illustrated in Fig. 1 Eabelbahnabschnitt, of which a plurality those arranged one behind the other to form a cableway of any length and can be connected to each other is made of two L-shaped profiled spars 1 and a floor 2 attached to the spars.

Preferably, the spars 1 are made of sheet steel of greater thickness than the bottom 2 made.

The spars 1 have an unequal angular profile and are like that arranged that the narrow spar legs 3 are directed towards each other while the wide spar legs 4 are arranged to run at right angles to the latter and striving upwards, projecting beyond the bottom 2 attached to the narrow legs 3.

To attach the bottom 2 are in the spar legs 3 along this extending webs 5 cut and bent bow-shaped upwards.

The base area of these webs 5 are corresponding in the edge parts of the bottom 2, square openings 7 arranged through which the webs 5 form-locking and reach through so that it cannot rotate.

A pin 8 securing this plug connection is through each web inserted through, which is supported with both end parts on the top of the floor.

In order to facilitate the insertion of the pin 5, are in the flanges 4 the webs 5 are provided opposite pin through openings 9.

The pins 5 have the same, circular shape over almost their entire length Cross-sections and are pointed at the front end in the insertion direction. To the the end of the pins 8 facing away from the tip 10, a countersunk head 11 is formed in each case, with the correct position of the pin 8 in a recess 12 of the spar legs 4 rests so that the head face of the pin 8 with the outside of the spar leg 4 ends flush at most.

The bow-shaped web 5 and the pin 8 are also designed so that that when driving in the pin 8 at least under elastic pretensioning of the web 5 the bottom 2 is pressed onto the spar web 3.

In order to at least make it more difficult to accidentally loosen the pin 8, the sharpened end of the pin can be angled.

Fig. 2 shows a pin 8 with an approximately centrally angled shaft zone 13, when the pin 8 is driven into the opening located under the web 5 14 engages automatically and thus prevents unintentional loosening of the pin 8, without the measures described above being necessary.

Thus, even with rounded corner corners 15 of the spars 1, the end faces the bottom beads 2b can be placed on the rail legs 4 with almost no play, are in the spar legs 4 along this extending, pushed through and inward beads 16 arranged approximately at the same level are provided on the upper sides of the base 2 (Fig. 3).

For this purpose, FIGS. 4 and 5 show further, possibly preferred Variants, namely in Fig. 4 in the spar leg 3 is a longitudinally extending, at a distance from the spar leg 4 arranged, upwardly pushed through bead 17 provided, in the area of which the bow-shaped webs 5 are formed.

In Fig. 5 is for the same purpose and also to simplify the perforation the pin through holes 9 in the spar leg 4 a pushed through to the outside Formed bead 18, which is arranged so that its lower flank to the spar leg 3 is arranged at the same level.

In addition, a pin 8 is shown in Fig. 4 with an approximately semicircular profile, on the upper, arched side of the shaft an upward striving with the web 5 corresponding bead 19 is formed, while in the shaft underside of the Bead 18 opposite a shaft constriction 20 is provided, which cause while the pen is being driven in, the sharpened end part of the pen moves automatically, namely through the on the underside of the web 5 itself supportive Bead 19, is bent upwards, through the shaft constriction 20 of this The turning process is favored and with which an even higher positional security of the pins 8 than has been achieved so far.

In Fig. 2 are also the two long sides of a cut and stirrup-shaped deformed web 5 arranged incisions 21 each over the Bending edges 22 of the webs 5 are formed so as to extend outwards.

This has the advantage that now when driving in a pin 8 the in the plane of the spar leg 3 extending zones 23 of the web 5 is elastic can spring through.

These measures allow even greater manufacturing tolerances than be bridged so far.

It has been found to be particularly advantageous if the trimmed Web 5 initially bent over its entire length upwards in a bow-shaped manner and then in a further operation with the formation of the bending edges 22 partially into the Level of the bracket leg 3 are pushed back.

Furthermore, in Fig. 2 on the edge parts of the openings 7 inward directed tongues 24 cut, when placing the bottom 2 on the webs 5 of these are bent at least elastically upwards, so that even with large Manufacturing tolerances always a play-free system of the webs 5 in the openings 7 is achieved.

The spars 1 can be made of rolled, in particular cold-rolled, profile bars exist or be produced by folding sheet metal strips.

Instead of a base 2, a plurality of spars 1 can also be used Rungs are provided that have at least one breakthrough in their end parts 7 have, the latter being designed as shown so that at the Spars 1 attached rungs, these are non-rotatably connected to the bars 1.

All new items disclosed in the description and / or drawing and combination features are considered essential to the invention.
