  • a variant of such a wooden construction in the case of gable roofs is the so-called purlin roof structure 100, which is exemplified in Figure 1a is outlined.
  • Components of such a purlin roof structure 100 are rafters 110, which form the triangular cross section of a saddle roof with a horizontal ceiling 200, the rafters 110 preferably representing the isosceles sides of the triangle.
  • This triangle can span a plane perpendicular to the surface.
  • the plane spanned by the triangle can also be designed obliquely, for example in the case of a falling eaves.

  • the rafters 110 rest as inclined beams on the so-called purlins 121, 122, 123, which collect the vertical roof loads as longitudinal struts that run mostly horizontally to the ground and divert them onto posts 130 or vertical struts.
  • the so-called purlin 123 runs in the area of the ceiling 200.
  • the so-called ridge purlin 122 runs at the intersection of two rafters 110, that is to say in the top of the roof or in the tip of the triangular cross-section.
  • the roof inclination results from the specific inclination of the rafters 110, represented by the roof inclination angle or inclination angle ⁇ .
  • the connection point between the rafters 110 and the purlins 121, 122, 123 is typically implemented as a saddle connection 300.
  • Such a saddle connection 300 is shown in FIG Figure 1b shown by way of example using a connection between a rafter 110 and a purlin 120.
  • the rafters 110 have a form-fitting hold on a saddle 111, also called a kerve.
  • the shape of the saddle 111 is matched to the outer contour of the purlin 120 and to a predetermined angle of inclination ⁇ .
  • the saddle connection 300 is secured, for example, by a beam connector 301, shown here as a rafter-purlin anchor. This can be designed as a stamped and then bent sheet metal piece.
  • the beam connector 301 has a first section 302 which is attached to the purlin 120 and a second section 303 which is attached to the rafters 110.

  • the number of fasteners 304 used is matched to the given load. If necessary, holes have to be pre-drilled in the beams to accommodate nails.
  • the rafter-purlin anchor shown is shown in the "right version”. On the other side of the rafters 110, hidden from the viewer, there is a rafter-purlin anchor in the "left-hand version”.
  • left and right are to be understood as the perspective of a mechanic or a roofer who works (for example standing on a ladder) on the outside of the roof.
  • the right and left versions cannot normally be interchanged.
  • a roofer must always have the right version of a rafter-purlin anchor with them and at hand.
  • a so-called rafter nail 306 is usually used for additional hold. This is a long nail that is struck in the area of the saddle 111 after predrilling through the rafters 110 and into the purlin 120, the planned inclination angle ⁇ of the roof having to be taken into account when predrilling.

  • the DE 30 16 659 A1 relates to a support device for fastening a ridge slat with a U-shaped head part and legs diverging sideways downwards. It is envisaged to bend the legs outwards several times in order to adapt to different roof pitches by placing the different leg areas as parallel as possible to the respective roof battens on the roof battens adjacent to the ridge battens. This is to achieve the most possible rectangular interlocking of the divergent legs with those of the brackets on the adjacent roof battens. From the DE 32 13 358 A1 a similar support device is known, but the diverging legs can be made in several parts.
  • the DE 40 29 357 A1 has a U-shaped headboard to support a ridge purlin.
  • the head part is height-adjustable via a vertical adjusting screw with a V-shaped fastening device for a full support on beams underneath, e.g. a rafter joint.
  • the adjustable connector between the headboard and the V-shaped Fastening device instead of with a vertical adjusting screw, carried out by a rod-shaped support part and a spring clip holder, the spring clip holder holding the support part in a clamping handle in a self-locking manner.
  • the DE 198 49 507 C1 relates to a device with a U-shaped housing, in the legs of which two pressure plates are pivotally mounted, for temporarily clamping rafter heads in the ridge purlin area, so that when rafter heads are nailed to the ridge purlin, the rafters do not slip out of the intended position.
  • the swiveling pressure plates fit snugly against the top of two opposite rafters, regardless of the roof pitch angle.
  • the DE 10 2012 007 700 B4 relates to an angle connector for connecting a purlin roof of a purlin roof to a reinforced concrete ceiling.
  • the angle connector is placed with a first section on the reinforced concrete ceiling in such a way that its second section comes to rest on the foot purlin.
  • the DE 41 08 853 C2 relates to a beam connector for crossing beams, in particular for a rafter with a purlin.
  • the beam connector consists of a plate provided with bores with two part plates angled against one another, a part plate being connected to the first beam and the second part plate being connected to the second beam.
  • the beam connector described represents a variant of a conventional rafter-purlin anchor 301 (cf. Figure 1b ), whereby here the "left embodiment" and the "right embodiment” are more interchangeable.
  • the beam connector does not offer any tools for handling the roof slope.
  • the beam connector specified in claim 1 and the use of such a beam connector specified in claim 14 are proposed.
  • advantageous embodiments of the invention are specified in the dependent claims. It should be noted that the features listed in the following description as well as measures in can be combined with one another in a technically meaningful manner and show further refinements of the invention. The description additionally characterizes and specifies the invention, in particular in connection with the figures.
  • the invention relates to a beam connector for connecting a first beam, in particular a purlin, to a second beam, in particular a rafter, wherein the second beam crosses the first beam in an X-shape and the beam connector has a first section for connection to the first beam and a second Section which is adjacent to the first section at a common first bend, for connection to the second beam.
  • the beam connector additionally has a third section for connection to the first beam and a fourth section, which adjoins the third section at a common second bend, for connection to the second beam.
  • the second section and the fourth section of the beam connector are wholly or partially designed for full contact with one, in particular the same, side wall of the second beam. After assembly, the second section and the fourth section rest on the same beam side wall of the second beam, in particular the rafters.
  • the addition of the additional sections improves the stability of the beam connection, in particular for beam connections in the roof structure, for example between a rafter and a purlin, the rafter crossing the purlin in an X-shape.
  • the beam connector according to the invention is particularly suitable for use as a rafter-purlin anchor for use in roof construction.
  • rafters and purlins are usually referred to in simplified form, with "purlin” including every first beam and "rafters” every second beam, not only in the roof structure, regardless of its cross-section.
  • the beam connector can also be used to connect the rafters to a concrete slab so that the rafters lie on the concrete edge.
  • the beams to be connected are typically made of wood, but in principle any suitable material, for example a metal strut, can be used. “Adjacent” can be understood to mean that two sections have a common bend or edge, that is to say they touch one another on a bending axis and / or bending axis.
  • the rafters can be arranged "perpendicular" to the purlin by at least one Rafter wall runs perpendicular to a purlin wall. This means that a central axis or beam edge of the purlin runs perpendicular to a side wall of the rafter. For example.
  • this central axis of the purlin or the beam edge of the purlin can also run obliquely to all side walls of the rafters.
  • the rafters would form a point support with an edge on the edge of the purlin.
  • a saddle or a kerve i.e. an incision in the rafters, can be dispensed with by using additional sections on the beam connector. This avoids the disadvantage that such a saddle can weaken the beam under certain circumstances by reducing the beam cross-section, which means that additional stabilization measures are then required, particularly in roof construction.
  • the additional processing step of rafters for the manufacture of the saddle is also omitted, which makes assembly easier. An additional rafter nail can, but does not have to be used.
  • the first section and the third section of the beam connector are arranged at right angles to one another or form a right angle.
  • the right angle is preferably created by bending a flat sheet metal piece (flat sheet metal piece) once or several times, so that two sections of the flat sheet metal piece form the legs of the right angle.
  • the beam connector can be positively attached to the purlin with a rectangular cross-section so that the two sections lie flush against the purlin and one edge of the purlin is preferably arranged on or during the bend, i.e. the interior of the right angle.
  • the first or the third section are designed for top support on the purlin.
  • the vertical roof loads can be better transferred from the rafters to the purlin, which additionally stabilizes the roof structure statically.
  • a beam connector can thus replace the saddle or the peg in the rafters.
  • the first section and / or the third section can be pressed flat against the purlin using a screw clamp. This enables use as a saddle-rafter-purlin anchor, i.e. as a rafter-purlin anchor or beam connector with saddle for a rafter-purlin connection, because of the Beam connector already has the saddle integrated.
  • the fitter can "let go” of the beam connector in its final assembly position even before the fastening means (screws, nails) have been attached, even without the use of tines, without the beam connector changing its position or falls down. In principle, this enables assembly with one hand.
  • the first section preferably adjoins the third section at a common third bend.
  • the first section and the third section are like a single angle to one another (cf. Figure 1c ) educated.
  • the edge of the purlin can thus touch the inner region of the bend linearly along the longitudinal extent of the right angle or touches the interior of the right angle, and thus the underside of the first and third sections. Placed on the purlin, this makes it difficult to inadvertently slip during assembly, and after the attachment of fasteners, the purlin is securely gripped and held.
  • the first section and the third section can be spaced from one another in regions. In this case, the first section or the third section have no common edge or bend. As a result, the beam connector can still be placed on the purlin like a single angle, but the distance between the first section and the third section can save material.
  • the second section and the fourth section are arranged in one or all of the parts, for example for full contact with a flat beam wall.
  • the second section and the fourth section are arranged in whole or in part, for example for full or full contact with a side wall of a rafter.
  • the stability is further improved by the fact that two or more sections of the beam connector bear the loads of the rafters on the connection. When using two beam connectors, one on the left and one on the right of the rafters, there are a total of four flat sections on the rafters for receiving the loads. This includes the fact that the second section and the fourth section are formed as partial areas of a continuous flat sheet piece.
  • the second section and the fourth section can adjoin one another without being bent or bent relative to one another. This enables the two sections to be formed without additional manufacturing steps.
  • the second section and the fourth section can be spaced apart from one another in regions or, for example, have a recess or punched-out area, so that marking lines, for example a line tear or a horizontal tear, remain visible on the rafters. This recess or punching can also extend to the first section and the third section.
  • a boundary edge of the second section and a boundary edge of the fourth section are arranged at right angles to one another or enclose a right angle.
  • one of the two sections always absorbs above all the vertical roof loads and one of the two sections primarily absorbs the horizontal roof loads. Due to the right-angled arrangement of the two sections, identical beam connectors can be installed both on the left of a rafter and on the right of a rafter. As a result, the fitter no longer has to have different beam connectors at hand. This also prevents the left and right versions from being mixed up, making assembly much less prone to errors.
  • the beam connector can be mirror-symmetrical with respect to a first plane of symmetry and / or center plane. This ensures unrestricted usability of a beam connector on both sides of the rafters, which reduces the number of components required to assemble a roof truss and thus lowers the manufacturing costs for the necessary components and thus the assembly costs.
  • This symmetry in particular also means that the surfaces of the first section and the third section, and also of the second and fourth sections, are each congruent to one another.
  • a linear and / or punctiform contact and / or support is formed or can be formed between a bar edge of the first bar and an underside bar wall of the second bar.
  • this is to be understood in such a way that the rafters with an underside boundary wall lie tangentially and / or obliquely on a beam edge of the purlin, with a linear support underneath Forms a straight line.
  • punctiform supports or combinations of linear and punctiform supports are also conceivable. This is also an effect of the fact that a saddle or a bow is not necessary.
  • an upper-side boundary wall of the first bar and a lower-side bar wall of the second bar jointly enclose an acute-angled angle of inclination, the bar connector having an adjusting means for determining and / or determining the angle of inclination.
  • the bar connector having an adjusting means for determining and / or determining the angle of inclination.
  • an upper-side boundary wall of the purlin and a lower-side wall of the rafters together enclose the acute-angled angle of inclination of the roof slope, the beam connector having an adjusting means for determining and / or fixing the roof slope.
  • the angle of inclination of the rafters which is attached to the purlin with or without a saddle, ultimately determines the roof slope or the roof pitch.
  • the roof pitch is always measured towards the roof.
  • a smooth underside boundary wall of the rafters offers no orientation for fitting the rafters taking into account the specified angle of inclination.
  • This orientation can be made possible by an adjustment means on the beam connector, i.e. an aid for adjusting the roof slope.
  • the actual inclination of the rafters with respect to the purlin can also be determined or read using the setting means.
  • there is also structurally integrated information about the angle of inclination on each rafter-purlin connection which can be read if necessary. This enables subsequent checks, which can significantly increase the safety and quality of the execution. Assembly errors can be recognized early and corrected if necessary. This is particularly advantageous in the case of subsequent repair and renovation work in confusing or difficult-to-access places if a determination of the roof pitch would otherwise be associated with increased effort.
  • the setting means has one or more straight setting elements on the second section and / or fourth section.
  • a straight adjustment element can be used as a notch, groove, groove, Indentation or simply be formed as a recorded marking line.
  • the setting elements can be designed continuously or with interruptions.
  • the edge of the rafters and / or another underside boundary wall of a second beam can be placed against such an adjusting element and thus aligned on the basis of the predetermined roof pitch.
  • the corresponding setting elements can be arranged on both side walls of the second and / or the fourth section, which improves the versatility of the beam connector.
  • the arrangement of the setting elements can be the same on both sides, but can also be designed differently.
  • two or more setting elements are designed as straight, radially and / or radially arranged marking lines with a common origin as the intersection of the lines.
  • a label and / or scale can be provided at the end of such a line spaced from the origin to indicate the angle of inclination to be set or set, in particular the sloping roof to be set or set.
  • two angular dimensions can be provided at each such end, which add up to 90 ° to one another (for example 40 ° and 50 °).
  • an origin of the setting elements lies in a connection area between the first section and the third section. If the lower beam wall of the rafters lies directly on the beam edge of the purlin, the origin coincides with this beam edge of the purlin or it lies in the interior of the preferably right-angled bend and thus on the underside of the connecting area of the first and third sections of the beam connector. The origin therefore lies in the saddle or on the bending axis of the bend between the two sections which abut the purlin.
  • the setting elements thus run radially or radially away from the beam edge of the purlin, which enables the fitter to easily orientate himself when installing the rafters.
  • connection area between the first section and the third section forms a linear and / or punctiform contact and / or support for the second bar.
  • forms the connection area between the first section and the third section forms a linear and / or point contact and / or support for the rafters.
  • the rafters can thus also rest on the two sections that abut the purlin, forming a straight line.
  • the rafters no longer form a linear and / or punctiform support with the beam edge of the purlin, but with the beam connector itself. This is particularly advantageous when there is no space on the purlin for mounting the first and third sections next to the rafters is present, for example because a dormer is provided.

  • the in the Figure 2a The arrangement of rafters 110 and purlin 120 shown has an inclination angle ⁇ of approximately 42 °.
  • the rafters 110 can be manually or with a crane in the purlin roof structure 100 (cf. Figure 1a ) lifted and placed on the purlins 120.
  • the angle of inclination a i.e. the roof slope, can be read from each rafter-purlin connection.
  • the scale is only partially shown, but should ideally cover a range of 5 ° -85 ° in 5 ° steps or similar.
  • Figure 2b shows essentially the arrangement according to Figure 2a in a front view.

  • the underside of the beam wall 115 of the rafters 110 is at a distance from the beam edge 126 of the purlin 120, for example by resting the rafters 110 on a piece of flat sheet metal (cf.
  • the origin 420 in the connection area of the first section 302 to the third section 311, that is to say in the area of the third bend 321, can also have an offset with respect to the bar edge 126, the offset being able to correspond to the thickness of the flat sheet metal piece.

  • Figure 3 shows a beam connector 301, which is basically like a beam connector 301 already described (cf. Figures 2a-2c ) can be used. This is produced by first cutting a piece of flat sheet metal on one side up to a planned origin 420, so that two free edges, a first free edge 302a and a second free edge 311a, are formed. The two sections adjoining these free edges 302a, 311a form the first section 302 and the third section 311 in that the first section 302 is at an angle of 90 ° with respect to the second section 303 around the first bend 307 and the third section 311 with one An angle of 90 ° with respect to the fourth section 312 is bent around the second bend 314.
  • the first section 302 and / or the third section 311 thus preferably have a triangular geometry or, as shown, a trapezoidal geometry.
  • a third bend 321 between the first section 302 and the third section 311 is eliminated. Rather, the first section 302 and the third section 311 are formed at a distance 330 from one another, the two free edges 302a, 311a or an imaginary one Can cut extension in origin 420 and quasi form the legs of an equilateral triangle.
  • the second section 303 and the fourth section 312 remain as partial areas or partial sections of the connected flat sheet metal piece and are thus formed over a large area.
  • the coherent flat sheet piece of the second section 303 and the fourth section 312 lies fully flat against the beam side wall 117 of the rafters 110 after assembly is complete.
  • Adjustment elements 410 can thus be arranged with a scale of up to 90 °. Furthermore, a recess 430 can optionally be provided in connection with the setting elements 410 for an additional assembly aid in the transition area between the second section 303 and the fourth section 312, through which any markings or markings, such as a lace crack 431 and a balance crack 432 on the one behind it Rafters 110 remain visible to the user.
  • the recess 430 can be punched, for example, as a circular hole or hole with a three-quarter circle from the flat sheet piece which has not yet been bent, so that the recess 430 also extends to the first section 302 and the third section 311 and shortens the free edges 302a, 311a.
  • Figure 4a shows a beam connector 301 according to Figures 2a-2c with an additional fifth section 323 and an additional sixth section 325.
  • the fifth section 323 is connected to the first section 302, the connection resulting from a flat bend piece by a fourth bend 324.
  • the sixth section 325 is connected to the second section 303, the connection resulting from a fifth bend 325 from a flat sheet piece.
  • All six sections 302, 303, 311, 312, 323, 325 are formed as rectangular sections of a flat sheet metal piece and can be produced by bending in a total of five steps from a correspondingly cut flat sheet metal piece.
  • the surfaces of the second section 303, the fourth section 312, the fifth section 323 and the sixth section 325 are designed to be congruent to one another.
  • the second section 303 is aligned parallel to the fifth section 323 and the fourth section 312 is aligned parallel to the sixth section 325.
  • the beam connector 301 can thus be divided into two imaginary halves, which are arranged mirror-symmetrically to one another on a second plane of symmetry and / or center plane 360.
  • the rafters 110 lie on the third bend 321 to form a linear and / or point contact and / or are arranged at a short distance from the third bend 321.
  • the second section 303 and the fifth section 323, as well as the fourth section 312 and the sixth section 325 lie flat against two lateral, opposite walls of the rafters 110. In this way, they form a receptacle or guide rail of the rafters 110 in pairs, one pair each having a U-shaped profile. If the rafters 110 are connected to this variant of the beam connector 301 before the beam connector 301 is placed on the purlin 120 (cf. Figure 3b ), the first section 302 and / or the third section 311 must then be attached to the purlin 120. With a sufficiently large angle of inclination a, the sections abutting the purlin 120 are sufficiently accessible. Otherwise, fasteners 304 such as a rafter nail 306 (cf.
  • Figure 1b are driven by a correspondingly predrilled rafter 110.
  • the fastening openings 305 are enlarged in the corresponding section, which facilitates the assembly of the nail or the screw.
  • the first section 302 and / or the third section 311 can be enlarged accordingly and, if necessary, folded over on the purlin 120, so that the first section 302, the third section 311 and the additionally folded over section have a U-shaped profile.
  • Figure 4b shows the beam connector 301, which is placed on a purlin 120 for assembly.
  • the rafters 110 (cf. Figure 2 ) can now be inserted into the guide rail formed by the beam connector 301 and placed on the third bend 321 to form a linear and / or point contact.
  • a bar edge of the rafters 110 and / or an underside boundary wall 115 (cf. Figure 2 ) can be applied to one of the dashed lines, which setting elements 410 one Indicate setting means 400.
  • the angle of inclination ⁇ and the roof slope can thus be read on a label or on a scale, which makes assembly easier and more precise.
