Description

The invention relates to a steel profile support, which may also be referred to as a support profile or mounting profile made of steel, for Anmontieren of lines, such as water pipes, power cables or the like. The steel profile support according to the invention can be used for example in cantilevered halls, which are held primarily by concrete columns, which are arranged at a distance of usually more than 5 m from each other. In the case of self-supporting halls, neither the roof (a trapezoidal sheet) nor the side panels (sandwich panels) may be subjected to static loads. In such self-supporting halls, for example, supporting profiles can be mounted laterally on concrete pillars or transversely between concrete supports in order to carry cables to be laid in the self-supporting hall.

A generic support profile made of steel is known from the utility model DE 20 2005 006 528 U1 , The known support profile has a substantially square profile cross-section, which is formed by four adjoining profile peripheral walls. In the known support profile continuous fastening grooves are formed on two opposite profile peripheral walls in the profile longitudinal direction. In the other two profile wall sections, successive punched perforations in the form of individual slots are formed in each case in a row. The generic support profile is versatile, especially in the installation area, for example, for communication and data lines, supply lines of various kinds, such as electrical supply lines, supply lines for the gas and water supply, hot water supply, pipes for heating, sewers, etc. For this purpose, known support profiles, for example, with elbows, attached to each other or on walls, ceilings or floors of buildings. The slotted holes provided in the slotted profile peripheral walls allow attaching, for example, pipe clamps for piping or the like to install pipes. In the mounting grooves hammer head screws or wedge head screws can be introduced with their hammer or wedge head, for example, to attach two support profiles together. Due to the simple assembly, the known support profile has proven very successful in practice.

In the case of DE 20 2005 006 528 U1 known supporting profile are provided diametrically opposite profile peripheral wall pairs either with slots or with mounting grooves. The slots are to allow a connection of functional elements of various kinds, while the mounting groove should accommodate hammerhead screws, so that different types of attachment are available. Depending on the mounting direction is either a slot side wall or a mounting groove side wall front side for mounting additional functional elements or attachments ready.

When using the known support profile has been found that in particular inexperienced installation personnel not always the planned according to the orientation of the support profile taken into account, so that is ready to connect more functional elements after completion of the support profile assembly the wrong slot side or mounting groove side instead of the intended page. In the case of such assembly errors, the support profile, which has already been firmly anchored in a building structure, must be loosened and correctly replaced. This can lead to damage to the building as well as the support profile. In addition, the troubleshooting eliminates unnecessary assembly costs.

It is an object of the invention to overcome the problems of the prior art, in particular to provide a steel profile support whose installation in the planning phase is easy to design and which is fast, easy and low error prone to install in the installation phase, with a flexible mountability of various attachments, especially lines, to be ensured in a simple manner.

This object is achieved by the subject-matter of independent claim 1. Accordingly, according to the invention a steel profile support for mounting lines, such as communication and data lines, supply lines, for example for gas, water or hot water supply, sewers or the like provided, the four adjoining profile peripheral walls with a minimum wall thickness of 1 mm. Steel profile beams may have a length of more than 1 m, more than 5 m and / or less than 20 m, less than 10 m, preferably about 6 m. The steel profile carrier according to the invention has, in a longitudinal direction, preferably along at least 500 mm, 1000 mm or even its entire length, a substantially constant, rectangular cross-section transverse to the longitudinal direction. The rectangular profile cross section may have a substantially rectangular, preferably square, outer contour. Preferably, all profile peripheral sides are substantially the same length and / or width. It is clear that the corners of the rectangle may in particular have manufacturing-related curves. The profile cross section has a side length of at least 50 mm, preferably between 50 mm and 150 mm, in particular about 100 mm. The skilled person understands that the introduction of notches, oblong holes or the like in Profile walls or profile peripheral walls of the steel profile carrier is not to be regarded as a deviation from a substantially constant rectangular profile cross-section. Preferably, the circumferential perimeter walls define planes that intersect each other at an angle of 90 ° ± 5 °, preferably ± 1 °. The contact of the perpendicular adjoining profile circumferential walls may preferably be formed and / or rounded by bending, rolling and / or welding, in particular butt welding, one or more steel sheets or steel strips.

In a steel beam, precisely one or at least one of the four circumferential profiles has a mounting groove extending longitudinally, preferably at least 500mm, 1000mm, or completely along the steel beam for receiving a mounting wedge, such as a hammerhead nut or hammer head bolt, for mounting the Lines on. In this case, the fastening groove defines a preferably elongate and / or slot-shaped opening in the respectively associated circumferential profile wall. In the steel profile carrier, the respective attachment groove protrudes from its respective opening into the interior of the steel profile carrier and expands to form undercuts. The undercuts can serve as fastening abutment to be introduced into the mounting groove mounting wedge or hammer head of a hammer head screw. The fastening groove can be used, for example, for mounting lines by means of a fastening wedge or for fastening two steel profile beams to each other. Preferably, the width of the opening transverse to the longitudinal direction of the steel profile carrier is smaller than a largest clear width of the mounting groove parallel to the width of the opening. The width of the opening may be between 5 mm and 30 mm, preferably between 10 mm and 15 mm, in particular about 13 mm.

According to one aspect of the invention, the at least one, preferably each, mounting groove has two preferably diametrically opposed, undercut-forming wings extending away from the opening and transversely relative to a profile perimeter wall vertical in the steel beam an angle between 90 ° and 135 °, are oriented. Generally, the angle can be between 45 ° and 135 °. Preferably, one wing each may extend from a groove edge delimiting the opening and / or to a groove side face bounding the groove base transversely to the longitudinal direction. It is to be understood that, with regard to orientation, the groove edge, referred to as a vertical peripheral direction, extends from a plane inwardly into the cross-sectional profile, the plane being defined by the profile circumferential wall in which the fastening groove, its Wing is described, is arranged. The described profile peripheral wall vertical and the fastening groove and its wings thus relate to the same profile peripheral wall surface. By providing an additional wing, different from the profile outer peripheral wall, for realizing the undercut of the fastening groove, the fastening groove can provide an abutment for a fastening wedge with a predetermined spring action, which has proven to be advantageous in terms of assembly safety.

In a further development of a steel profile support according to the invention according to a preferred alternative, the wings each have an angle of at least 90 ° and at most 120 °, preferably at least 100 ° and at most 110 °, in particular about 105 °, relative to the profile peripheral wall vertical pointing in the steel profile carrier. In the embodiment of the steel profile carrier according to this alternative wing, the wing is guided back towards the inside of the profile peripheral wall and may preferably be brought into inside contact with the profile peripheral wall, which increases the mounting strength of the steel profile carrier. Due to the increased stiffness of the wing setting phenomena that can lead to a reduction in the holding force of a hammer head mounting screw can be avoided.

According to a preferred embodiment of a steel profile carrier according to the invention, at least two, three or each of the four circumferential profile walls each have at least one fastening groove extending in a longitudinal direction for receiving a fastening wedge for mounting the lines. The fastening groove defines an opening in the respective circumferential profile wall. From the opening, the respective fastening groove protrudes into the interior of the steel profile carrier and expands to form undercuts. Accordingly, it is possible to provide at least one fastening groove extending in the longitudinal direction on two preferably opposite circumferential walls of the profile, on three circumferential profiles of the walls or on all four circumferential profiles of the profile.

It has surprisingly been found that the use of similar Befestigungsnuten on all four profile peripheral walls of a steel profile support advantageously not only excludes incorrect assembly, but is also particularly well suited for safe and easy installation of different attachments. In particular, in the longitudinal direction of the steel profile carrier fixing screws can be arranged and fixed along the entire length of the steel profile carrier without, as previously, to be fixed to the position of the slots for attachment to the slot sides. At the same time unnecessary the assembly planning with regard to the optimal alignment of a known steel profile carrier with different types of circumferential profile walls on the one hand slots and on the other hand mounting grooves. Contrary to the common prejudice that slots are cheaper compared to Befestigungsnuten due to the lower material requirement and the lower production cost and consequently are generally preferred, it has surprisingly been found that when looking at the total cost of purchase and installation of a steel profile support, steel profile according to the invention due the significant reduction in planning and installation costs in practice can lead to significant cost savings.

According to a preferred embodiment of a steel profile support according to the invention, the steel profile support has a wall thickness which is preferably full, in particular also in the fastening grooves, and / or along its entire extent in the longitudinal direction.

According to a preferred embodiment of a steel profile carrier according to the invention, which can be combined in particular with the previous one, the wall thickness of the steel profile carrier is greater than 0.5 mm and / or smaller than 5.0 mm, in particular greater than 1.0 mm and / or smaller than 3 , 00 mm, preferably greater than 1.3 mm and / or less than 2.8 mm. For this wall thickness range, it has been shown that a particularly good balance between high rigidity of the steel section beam and the lowest possible dead weight can be achieved. For a particularly low weight, the wall thickness is preferably greater than 1.1 mm and / or less than 1.3 mm, more preferably about 1.25 mm. According to a particularly optimized for low weight design, the wall thickness is preferably greater than 1.3 mm and / or less than 1.7 mm, more preferably about 1.5 mm.

The radius of curvature can be dimensioned depending on the preferably constant wall thickness of the steel profile carrier, in particular the radius of curvature can be at least 1.2 times or at most twice the wall thickness of the steel profile carrier. The radius of curvature of a groove edge can preferably pass on the one hand into the profile circumferential wall, in particular in an aligned and / or seamless manner, and on the other hand, in particular, pass into a wing forming an undercut of the fastening groove in a flush and / or seamless manner. By using a curved transition between the outside of the profile peripheral walls and the mounting groove can be ensured in a simple manner that for the fitter no risk of injury during installation of the steel profile carrier is accompanied.

According to a preferred embodiment of a steel profile according to the invention, which can be combined with the previous, the respective mounting groove is centered on each, d.

The center axis is preferably cut by the profile peripheral wall vertical, which is arranged at the same distance from the two adjacent profile peripheral walls, which are each provided laterally of the profile circumferential wall associated therewith to the fastening groove. Due to the mirror-symmetrical and central design of the mounting groove is ensured in a particularly simple manner that several steel profile support compatible with each other are particularly well suited for easy installation.

According to a preferred embodiment of a steel profile support according to the invention, which can be combined with the previous, each fastening groove has a closed inner contour, which may optionally be broken by punching, embossing, slots or the like. Alternatively or additionally, the fastening groove is formed integrally with the material of the associated circumferential profile wall. Such a mounting groove can be made in a particularly simple manner by bending or rolling rollers made of the same material as the profile peripheral wall, for example a steel strip. In particular, the attachment groove has a groove bottom surface which preferably extends plane-parallel to the profile peripheral wall, in particular groove side surfaces arranged opposite one another, preferably plane-parallel and / or transversely, preferably perpendicular, to the groove bottom surface and / or the associated profile peripheral wall between the opening and the groove bottom surface.

Preferably, the inside width between the opposing groove side surfaces measures at least 10 mm and / or at most 50 mm, preferably about 30 mm ± 5 mm. In relation to a side length or edge length of the associated profile peripheral wall, the distance between the groove side surfaces may preferably be between one fifth and one third. The distance of the groove side surfaces in relation to the size of the opening width of the mounting groove and / or the side length of the associated peripheral profile wall allows for this dimensioning a particularly stable steel profile carrier design. In particular, between an optionally realized as part of the mounting groove and the groove bottom surface in the shortest distance of at least 5 mm, preferably at least 8 mm, in particular about 10 mm, so that a mounting wedge, such as a shoe or a hammer head of a hammer head screw, sufficient size well can be inserted into the mounting groove and anchored there.

In the following figures, the same or similar reference numerals are used for the same or similar parts or features.

In 1 to 3 the support profile according to the invention is generally denoted by the reference numeral 1 characterized. The steel profile carrier 1 may alternatively be referred to as a support profile or mounting profile and is made as a closed box body profile. The steel profile support can be made for example by rolling or bending of a single steel strip. It is also conceivable to produce a steel profile carrier by rolling rolls of two or more steel strips and then welding the plurality of steel strips.

The steel profile carrier 1 consists of a steel material that can be provided with a surface coating, such as zinc, for corrosion protection. The four pairs of diametrically opposite profile peripheral walls 11 . 13 . 15 . 17 connect substantially at right angles to each other. In the profile perimeter corners 12 . 14 . 16 . 18 between each two adjacent profile peripheral walls 11 and 13 . 13 and 15 . 15 and 17 or 17 and 11 may be due to production, for example, due to bending or profile rolling, curves.

Each of the perimeter walls or profile wall sections 11 . 13 . 15 . 17 is substantially the same length and width with a circumferential width of about 10 cm ± 10 mm transverse to the longitudinal direction L of the support profile 1 , so that the rectangular profile cross-section forms transversely to the longitudinal direction L. According to an alternative embodiment (not shown), a steel profile carrier may be dimensioned such that each two opposing tread circumferential walls have the same width, with one pair of opposed tread circumferential walls having a short circumferential width and the other pair of opposed tread circumferential walls having a long circumferential width. For example, a short circumferential width may be 5 cm and an associated long circumferential width 10 cm. Alternatively, a short circumferential width may be 10 cm and the long circumferential width 15 cm. Such a steel profile carrier would have a rectangular profile cross-section with a substantially rectangular profile circumference.

Preferably, the distance x, y from the center M of the opening 23 relative to the associated perimeter wall (e.g. 17 ) adjacent profile peripheral wall (eg 11 and 15 ) in a square profile cross section in each case about 50 mm. In a rectangular profile cross-section with different short and long circumferential widths, the distance of the center line M to the adjacent circumferential profile wall may preferably correspond to half of the shorter circumferential width. In particular, the center M of the slot opening 23 to the nearest adjacent perimeter wall about 50 mm.

The profile carrier 1 extends in a longitudinal direction L over up to 10 m, with a length of 5 m to 7 m, in particular about 6 m ± 30 cm is preferred. This length has proven to be particularly practical for use in conventional cantilevered halls. In the longitudinal direction L, the circumferential profile walls extend 11 . 13 . 15 and 17 with the centrally arranged therein fastening grooves 21 parallel to each other and parallel to the longitudinal direction L. The fastening grooves 21 extend in the illustrated preferred embodiment over the entire length of each circumferential wall profile 11 . 13 . 15 and 17 , It is also conceivable that a fastening groove extends only over part of a circumferential profile wall. In one, two, three or all four mounting slots 21 Through openings, in particular slots (not shown) may be provided, which may serve for additional attachment of attachments.

Each fastening groove 21 has a slot-shaped opening 23 that are in the profile perimeter wall 11 . 13 . 15 . 17 , which the respective fastening groove 21 has formed. Starting from the opening 23 the groove extends 21 pocket-like in the interior 3 of the steel profile carrier 1 , The fastening groove 21 widens inwards into the steel profile carrier 1 transverse to the longitudinal direction L and away from a center line M centered along the longitudinal extent L of the opening 23 is defined, gone. The inside 3 into the steel profile support and away from the opening 23 projecting inner contour of the mounting groove 21 is through two diametrically opposed wings 37 realized. The foot of the wings 37 is formed by a radial bend of the steel sheet, and forms the opening 23 the fastening groove 21 delimiting Nutrand 25 , The steel sheet, which the profile peripheral walls 11 . 13 . 15 . 17 is at the bottom edge 25 bent or folded over and goes to form a radius of about 3 mm in the wing 37 above.

According to the first embodiment of a steel profile carrier according to the invention, which in 1 to 3 is shown with different wall thicknesses S realized the wing 37 a return to the outside 53 the profile perimeter walls 11 . 13 . 15 respectively. 17 , The profile perimeter wall 11 . 13 . 15 respectively. 17 is substantially flat and defines a plane along the longitudinal direction L and across it. Perpendicular to this plane preferably extends through the midpoint line M of the opening 23 a profile perimeter wall vertical V to be assumed with an orientation on the respective perimeter wall 11 . 13 . 15 or 17 and into the interior 3 of the steel profile carrier 1 is directed.

The first version is the wing 37 oriented at an obtuse angle α relative to the profile perimeter wall vertical V. The angle α may be in a range between 90 ° and 135 ° and is preferably about 115 °. In this case (even at angle β) is to be assumed by a tolerance band of ± 5 °, with particularly accurate production ± 1 ° 30 '.

Will be in the mounting groove 21 introduced a retaining wedge or, for example, the hammer head of a hammer head screw, it is supported in the embodiment according to 1 to 3 on the inside of the mounting groove at a transition between the rounded Nutrand 25 and the wing 37 from. As in 2 at the steel profile carrier 1 shown with a wall thickness of 2.5 mm, the wing can 37 down to the inside 51 the profile perimeter wall 11 . 13 . 15 respectively. 17 be traced back so that the wing 37 for holding a fastening screw or the like in two places against the inside 51 the profile perimeter wall 11 . 13 . 15 respectively. 17 supported. The refolding of the grand piano 37 at an angle of 90 ° or more to the profile peripheral wall vertical V has also come into consideration with regard to roll rolling production of a steel section beam 1 made of a single steel strip proved to be particularly advantageous.

The representations of the 2 and 3 differ essentially only by the different wall thickness S, which in the steel profile carrier 1 in 3 about 1.5 mm ± 0.1 mm and the steel profile support 1 according to 3 is about 2.5 mm ± 0.1 mm. The width B of the opening 23 each mounting groove 21 is about 10 mm to 15 mm, preferably between 13 mm and 14 mm. The groove bottom has a clear width W of between 25 mm and 35 mm, preferably between 29 mm and 30 mm. The groove depth A perpendicular to the associated profile peripheral wall 11 . 13 . 15 respectively. 17 is about 5 mm to 15 mm, preferably 10 mm ± 0.5 mm. The groove bottom is through a flat groove bottom 33 formed, which is plane-parallel to the respective profile peripheral wall 11 . 13 . 15 respectively. 17 , in particular the outside thereof 53 extends. Perpendicular to the profile floor 33 and the respective perimeter wall 11 . 13 . 15 respectively. 17 extend opposing plane-parallel side walls 35 the groove 21 , Because the groove edges 25 , the wings 37 , the groove sides 35 and the groove bottom 33 are integrally formed, preferably integrally with the associated profile peripheral wall 11 . 13 . 15 or 17 , makes every groove 21 a closed bag 31 , Especially at the groove bottom 33 can the bag 31 for example, by a slot, which preferably extends in the longitudinal direction L, be broken in sections.

In the 4 and 5 illustrated another embodiment of a steel profile carrier according to the invention 2 is different from the one in 1 to 3 illustrated steel profile support 1 essentially only by the other shape of the mounting groove 22 , Incidentally, this embodiment can be configured according to the invention. In the steel profile carrier 2 is the mounting groove 22 characterized particularly coated or galvanized designed that the wing 37 extends at a relatively acute angle relative to the profile peripheral wall vertical of the highest 90 °. This way is between the inside 51 each to the groove 22 associated profile perimeter wall 11 . 13 . 15 or 17 and the wing 37 a convex split cavity whose smallest width is at the transition of the inside 51 the profile perimeter wall 11 . 13 . 15 respectively. 17 to the curved groove edge 25 is present.

The internal dimensions of the mounting groove 22 correspond to the other angle β of the wing 37 essentially the above for 1 to 3 mentioned. As in 5 shown, the groove depth A is to be determined between the groove bottom 33 and the transition between groove side 35 and wings 37 , The depth A of the groove 21 or 22 is generally measured at the shortest distance A between the groove bottom 33 and the wing 37 because this distance determines the maximum size of a deployable mounting wedge, such as a hammer head of a hammerhead bolt.

For the different steel profile beams according to 2 . 3 and 5 are one or more welds 55 which connect individual formed steel strips, shown at different possible points of the profile carrier. The welds 45 each extend preferably in the longitudinal direction L over the entire length of the steel profile carrier 1 or 2 ,

at 2 shows a steel profile carrier 1 which is formed from a single steel band and at which the weld 45 in the profile circumference corner 12 between the profile pages 11 and 13 is provided. At this point, the opposing marginal edges extending in the longitudinal direction L abut 41 . 43 the single steel band together. In order to avoid injury to the installation personnel or damage, in particular scratching of surface coating, the steel profile support along the weld 45 surface-treated, for example by planing and / or grinding.

In the 3 illustrated embodiment is exemplary with two extending in the longitudinal direction L welds 45 provided on the groove bottom 33 are provided. The steel profile carrier 1 according to 3 consists of two steel bands, each extending laterally in the longitudinal direction L, and marginal edges 41 and 43 have, which are aligned and welded together.

At the in 5 illustrated steel profile support 2 are two in the longitudinal direction L over the entire length of the steel profile carrier 2 extending welds 45 in the opposite profile perimeter corners 12 and 16 intended. The steel profile carrier 2 is formed from two formed sheets or steel strips whose respective marginal edges 41 and 43 clash. This can be in a steel profile carrier according to the invention 2 as in 1 to 4 represented the case.

It is to be understood that the angles (α, β) described in the respective embodiments between profile peripheral wall-vertical V and wing 37 , Wall thicknesses S and arrangement and number of welds 45 can be variably combined. The features disclosed in the foregoing description, the figures and the claims may be of importance both individually and in any combination for the realization of the invention in various embodiments.
