Definitions

  • the present invention relates to a bracket and a tubular bar for the formation of webs that run transversely and/or parallel to the roof trusses of a weather protection roof and are detachably fastened to them for carrying out assembly or cleaning work in the roof area, and a weather protection roof with webs of this type.
  • Weather protection roofs are known as temporary roofing for construction sites or at events, which consist of a framework construction comprising two or more roof trusses running parallel to one another, which are connected via transverse purlins and diagonal struts to absorb shear forces acting in the longitudinal direction of the roof truss.
  • Each roof truss is usually a truss girder, which often has a kink in a ridge area and has at least two chords, an upper chord and a lower chord, with one of the chords, usually the upper chord, having laterally running keder rails for pulling in the edge keder from the between roof skin elements, usually roof tarpaulins, clamped to adjacent roof trusses.
  • These half-timbered roof structures are supported at the desired height in the eaves area using scaffolding or another support.
  • weather protection roofs with three-belt roof trusses are also known, in which the keder rails are not carried in front of the upper chord, but rather by a central chord that runs largely parallel to these between the upper and lower chord, so that the upper chords of the roof trusses are above the roof skin in the finished weather protection roof run and protrude beyond them.
  • a problem that arises when using such weather protection roofs is that work often has to be carried out in the roof area. This can be assembly work to erect or dismantle the roof itself or routine maintenance or cleaning work.
  • the EP 2 984 255 B1 proposes, for example, a mounting bridge which is hung along a roof truss by means of a supporting structure. This creates a working platform which runs at the height of a roof truss or below it along the roof truss.
  • This mounting bar also necessarily runs below the roof skin due to its laterally suspended attachment and therefore the top of the roof skin is not directly accessible.
  • the disadvantage is that with the web elements proposed there, only webs running parallel to the roof trusses can be walked on safely.
  • the upper side of the running area necessarily has a more or less oblique angle to the ground, ie it is not flat. This makes committing, especially when wearing one Last, in bad weather or in the dark, uncomfortable and dangerous.
  • the object of the present invention is therefore to create an access option that can be detachably fastened on the top side of a weather protection roof, which allows safe and comfortable inspection at will transversely and/or parallel to the roof trusses of the weather protection roof.
  • a system of parts comprising a bracket according to claim 1 and a tubular bar according to claim 8, by means of which a weather protection roof according to claim 12 can be realized, which has a web on the upper side which, using two or more brackets according to claim 1 and /or tubular bars according to claim 8 is formed.
  • a first aspect of the invention is a bracket for creating a web that runs transversely, in particular essentially perpendicularly, to the roof trusses.
  • the console of the invention includes an upper and a spaced apart and non-parallel aligned lower strut.
  • the two struts can be designed as hollow profiles, for example with a round or square cross section, and are connected to one another via connecting pieces, which can be hollow profiles of the same type as the struts. In order to achieve the desired mutually inclined alignment of the two struts, the two connecting pieces differ in length.
  • the lower strut has one or more fastening means, in particular, for fixing to a roof truss of the weather protection roof in the form of a clamp or half-coupling consisting of an articulated upper and lower part, which encompasses a profile of the roof truss, for example the upper chord, and can be fixed to it by means of a friction fit.
  • the present invention proposes a tubular bar for forming webs running essentially parallel to the roof trusses.
  • the tubular bar comprises a spar with connection means to a profile of the roof truss at the opposite ends.
  • two tubular bars are detachably connected or fastened to two roof trusses at a distance from one another and aligned essentially parallel to one another, and a covering is placed on the bars of the tubular bars.
  • the covering forms a running area of the web segment created in this way and is aligned at least essentially parallel to the roof trusses.
  • the covering it is also conceivable for the covering to run at an acute angle to the roof trusses, provided that it is appropriately prepared for this, for example by means of securing pins or retaining clips protruding on the underside.
  • the distance between the connection means at the opposite ends of the tubular bar must correspond at least to the distance between two adjacent roof trusses of the weather protection roof.
  • two or more roof trusses can be mounted on a weather protection roof, which span a roof skin between them, detachably attachable webs are created, by means of which the entire top of the roof for clearing or assembly work is accessible.
  • the webs created by means of the brackets do not run parallel to the direction in which the roof trusses extend, but rather transversely thereto, ie at an angle other than zero.
  • these webs run perpendicular to the roof trusses, ie to the direction in which they extend.
  • the webs created using the tubular bars according to the invention run essentially parallel to the roof trusses.
  • two or more consoles are fastened to two different, for example adjacent, roof trusses on the top side of the roof skin.
  • this has half-couplings on the lower strut as fastening means, by means of which the console is clamped to the upper chord of a roof truss.
  • These half-couplings comprise two half-rings, which are placed around a round profile like a sleeve and can be connected to one another by means of screws, as a result of which the coupling is frictionally clamped to the lateral surface of the profile.
  • Other fasteners that allow the console to be securely fixed are known to those skilled in the art and may also be used.
  • At least one covering is laid between every two brackets to create a walking area.
  • This is preferably an elongated, approximately rectangular plank. to the short ones This can be equipped with hooks on the end faces, with which it is hung on the respective upper strut of the consoles. This creates a web according to the invention.
  • the weather protection roof usually has a sloping roof with a certain sloping roof angle. If the upper and lower struts of the console were aligned parallel to one another, the running surface of the covering would be inclined in its transverse direction relative to the ground. This is undesirable and dangerous because it can cause a person on the dock to slip off the side of it. This danger exists in particular in bad weather, for example with rain and/or wind, and in the dark and/or when the person is carrying a load.
  • the invention advantageously reduces or avoids this risk by arranging the upper and lower struts at an angle to one another and attaching the console to the sloping roof trusses in such a way that the longer of the two connecting pieces between the upper and lower struts is positioned roof down.
  • the slant angle of the running surface of the covering is reduced or even zero if the angle between the upper and lower strut corresponds to the slant angle of the roof.
  • side protection in the form of a railing can be created as additional security when using a suitably prepared console.
  • an embodiment of the console according to the invention with a vertical post is used, attachment points for side protection, for example for railings, being provided on the vertical post.
  • a web of the weather protection roof according to the invention created using the bracket of the first aspect of the present invention comprises at least one segment of two brackets fastened to different, possibly adjacent, roof trusses and a covering.
  • the bridge can be expanded with additional brackets and decking.
  • it can be widened by placing two decks next to each other on the two brackets.
  • the web can be placed near the ridge or at the eaves of the roof running parallel to them.
  • An oblique course, beginning at the eaves and continuing to the ridge, is also conceivable. Even with such a course, an inclined position of the running surface transversely to the direction of the coverings is advantageously avoided.
  • the web can also be designed in such a way that the angle between its segments, or their coverings, and the roof trusses changes over the course of the web.
  • a first segment can run parallel to the eaves of the roof, i.e. at a right angle to the roof trusses, a second segment at a first sloping, approximately an acute, angle to the roof trusses, a third segment in a second sloping, approximately an acute angle or an obtuse angle, etc.
  • a final segment could then again run at right angles to the roof trusses, say along the ridge or eaves.
  • the bracket according to the first aspect and the tubular bar according to the second aspect are preferably used together in order to be able to reach the entire upper roof surface of the weather protection roof by creating webs that run transversely or parallel to the roof trusses and consist of one or more segments.
  • an end face of a covering of a segment of a parallel/transverse web should abut a longitudinal side of a covering of a transverse/parallel web.
  • the webs formed using the bracket or the tubular bar can each comprise only a single web segment. Alternatively, they can also be extended by additional segments. In the case of a web running transversely to the roof trusses, this can be done by attaching a further bracket according to the invention to a roof truss that is different from the first two roof trusses and placing a covering on this and on one of the two first brackets.
  • one or more further tubular bars according to the invention are connected to the same roof trusses to which the tubular bars of the first web segment are already connected, these being parallel to the tubular bars of the first Web segment are aligned and spaced so that one or more additional pads can be placed in extension of the pads of the first web segment.
  • This lengthening can be continued until the web or webs are of the desired length and/or all areas of the roof can be reached.
  • the tubular bar according to the invention With the bracket according to the invention, the tubular bar according to the invention and the webs that can be produced with it running transversely and/or parallel to the roof trusses, a comfortable and safe upper side accessibility of a weather protection roof is made possible in a surprisingly simple and effective way.
  • the detachable webs according to the invention are particularly useful in the event that the roof skin is a keder tarpaulin, since such tarpaulins are hardly walkable: on the one hand, the keder tarpaulin could be locally overloaded by a person and tear, on the other hand, such a flexible tarpaulin represents a very swaying and smooth ground on which walking is hardly possible safely.
  • the material of the console and the frame is basically arbitrary, as long as the necessary strength is guaranteed.
  • the console can therefore be made of wood, metal, fiber composite material or a combination of the aforementioned materials, for example.
  • Preferred the console and/or the tubular bar consists of an aluminum alloy or steel.
