Definitions
- the invention relates to a beam connector for connecting a first beam to a second beam, the first beam crossing the second beam in an X-shape, according to the preamble of claim 1.
- the invention relates to a rafter-purlin anchor for anchoring a rafter to a Purlin according to the preamble of claim 1.
- the invention further relates to a beam connector for establishing a connection between a rafter and a purlin according to claim 14.
- Saddle roofs or pent roofs typically have a wooden structure below their roof surface to support the roof surface.
- 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 ceiling 200 is designed, for example, as a concrete ceiling and is supported by the vertical house walls 210.
- 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 beam connector 301 can be designed as a perforated plate with fastening openings 305 for receiving fastening means 304 (screws or nails).
- the first section 302 and the second section 303 are formed, for example, as partial surfaces of a perforated plate which are bent at right angles to one another about a first bend 307.
- 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.
- FIG. 1c a beam connector 301 designed as a single angle, which likewise has a first section 302 and a second section 303, which are arranged at right angles to one another and are connected to one another via a first bend 307.
- Figure 1d shows a connector designed as a double bracket 308, as it is also offered by the company Primo-Befest Trentsstechnik GmbH. In order to form such a double angle 308, a correspondingly designed flat piece of sheet metal is bent or bent a total of three times.
- the double angle 308 points analogously Figure 1c a first section 302 and a second section 303, which are connected to one another via a first bend 307 of a bent piece of sheet metal.
- a second single angle is provided, which comprises a third section 311 and a fourth section 312, which are connected to one another via a second bend 314 of a bent piece of sheet metal, forming a right angle.
- the first single angle and the second single angle form a further right angle, mirror-symmetrical to a first plane of symmetry and / or center plane 350, between the first section 302 and the third section 311, the first section 302 and the third section 311 via a third bend 321 bent sheet metal piece are interconnected.
- This double bracket 308 can be used, for example, to connect a column or a beam to the floor.
- fasteners 304 cf. Figure 1b
- elongated holes 322 can be provided in the double angle.
- 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 fasteners screws, nails
- the fasteners must be driven through the rafters so that the fasteners are then passed through preferably enlarged fastening openings or elongated holes in the first and / or third section can be brought into operative connection with the purlin.
- the rafters must be pre-drilled according to the angle of inclination of the roof slope.
- the partial areas of the flat sheet metal piece in the area of the first and / or the third section can be enlarged accordingly, so that the fastening openings are still accessible for fastening means even when the rafters are installed.
- the origin for the adjusting elements can be arranged in this embodiment, depending on the selected thickness of the flat sheet piece for the first and third sections with an offset relative to the beam edge of the purlin, the origin nevertheless being in the outer space on the extended bisector of the preferably right angle, which the include first and third sections. It thus lies, for example, on the top side or above on the sheet metal edge between the first and the third section.
- a fifth section which is connected to the first section and / or a sixth section, which is connected to the third section, is for the beam connector for connection to the second beam, i.e. in the roof structure, for example with the Rafters, provided.
- a beam connector thus has at least one additional section, or even better two additional sections, for attachment to the rafters.
- the stability of the connection between rafters and purlin can be increased to such an extent that a second beam connector, for example in the left and in right variant, can be dispensed with.
- the rafter can be attached to the purlin with a single beam connector.
- the first section, the second section and the fifth section and / or the third section, the fourth section and the sixth section form a connector with a U-shaped profile for guiding and / or receiving the second Beam, so in the roof structure, for example, rafters, between the second section and the fifth section and / or the fourth section and the sixth section.
- the second and the fifth section of the beam connector thus form the legs of the U-profile, while the first section represents the central region of the U-profile.
- the fourth and the sixth section of the beam connector form the legs of a further U-profile, while the third section represents the central region of this further U-profile.
- the central regions of two U-profiles are preferably arranged at right angles to one another around a bend in a flat piece of sheet metal.
- the beam connector is mirror-symmetrical with respect to a second plane of symmetry and / or center plane, the second plane of symmetry and / or center plane running perpendicular to the first section and / or the third section.
- a quasi-symmetrical guide and / or rail for receiving the rafters is thereby formed, the legs of the U-profiles abutting against two opposite walls of the rafters.
- the rafters are thus limited by a single beam connector against unintentional slipping to both sides.
- Corresponding setting elements can also be provided on both side walls of the second, fourth, fifth and / or sixth section for a beam connector with five or six sections.
- One or more stiffening elements for example a rib reinforcement, can advantageously be arranged on the beam connector between two adjacent sections.
- bending back and / or bending open of two mutually bent partial surfaces of a flat sheet metal piece can be prevented and other loads caused by bending and / or torsion can also be better absorbed.
- all can the expert known features, as are typically used in assembly elements for assembling a roof structure, are added to the beam connector.
- the beam connector can also be made with a single or multi-color finish.
- stiffening elements there are, for example, drive-in prongs, assembly tines and / or assembly pins that drill and / or slide into the wood of a beam when a fastening element is attached for locking and thus prevent or complicate unintentional slipping after hanging up.
- a beam connector in one of the previously described versions for creating a connection between a rafter and a purlin in the roof construction.
- the purlin can also be designed as a concrete slab or roof slab.
- FIG 2a . 2b and 2c show a rafter 110, which rests obliquely on a beam edge 126 of a purlin 120 to form a linear contact.
- the upper-side beam wall 125 of the purlin 120 closes and the underside of the beam wall 115 of the rafters 110 forms an acute-angled angle of inclination ⁇ , which can correspond to the roof inclination of a finished saddle roof.
- a saddle 111 or a kerve does not have the rafters 110.
- a beam connector 301 which acts as a saddle beam connector 301, the saddle 111 (cf.
- Figure 1b can be dispensed with, has a first section 302 and a third section 311 for the full-surface support on the purlin 120, which, quasi as with a single angle (cf. Figure 1c ), from a flat sheet, bent at the third bend 321, are interconnected.
- the illustration shows a beam connector 301, which is mounted on the left of the rafters 110, but can also be mounted on the right of the rafters 110 (cf. Figure 2c ).
- the beam connector 301 can thus be mounted on both sides of the rafters 110.
- the second section 303 From a terminal edge of the first section 302 there is furthermore, at a right angle, bent around the first bend 307, the second section 303, which is designed to fit flush against a boundary wall or beam side wall 117 of the rafter 110. From a terminal edge of the third section 311, at a right angle, bent around the second bend 314, there is the fourth section 312, which is designed to abut the same beam side wall 117 of the rafter 110 as the second section 303. All designated sections 302 , 303, 311, 312 are preferably formed as rectangular sections of a flat sheet metal piece. A plurality of fastening openings 305 for receiving fastening means 304 (cf. Figure 1b ) intended.
- the number of fasteners 304 actually used results from the expected load.
- the second section 303 lies in one plane with the fourth section 312, a boundary edge 303a of the second section 303 enclosing a right angle in a quasi L-shaped manner with a boundary edge 312a of the fourth section 312. Due to the symmetrical design (cf. Figure 1d ), a second beam connector 301 of identical construction can also be mounted to the right of the rafters 110 for increased stability. In the case of a similar assembly to the right of the rafters 110, the second section 303 of the beam connector 301 would not point essentially vertically upward, as shown, but the fourth section 312 (cf. Fig. 2c ).
- another angle can be selected instead of a 90 ° angle or right angle, depending on the inclination between rafters 110 and purlin 120. Possibly. the user must determine the angle between the first section 302 and / or the adjust the second section 302 or the third section 311 and the fourth section 312 by hammer blows so that the sections each lie flat against rafters 110 or purlin 120.
- the angle of inclination ⁇ ultimately determines the roof slope.
- the beam connector 301 could be preassembled on the rafter 110.
- the first section 302 and the third section 311 can be replaced with a saddle connection 300 with a saddle 111 (cf. Figure 1a, 1b ) or a Kerve, simply applied flat to the purlin 120.
- setting means 400 are provided, wherein in the illustrated embodiment of the invention the setting means 400 has setting elements 410 with straight lines.
- 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 origin 420 of the setting elements 410 coincides with the beam edge 126.
- 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.
- the origin 420 is preferably arranged on the sheet edge.
- Figure 2c shows the arrangement according to Figure 2a and 2 B in a top view.
- the first section 302 rests on the top-side beam wall 125 of the purlin 120
- the third section 311 rests on the top-side beam wall 125 of the purlin 120.
- 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.

Es ist darauf hinzuweisen, dass die in der nachfolgenden Beschreibung einzeln aufgeführten Merkmale sowie Maßnahmen in beliebiger, technisch sinnvoller Weise miteinander kombiniert werden können und weitere Ausgestaltungen der Erfindung aufzeigen. Die Beschreibung charakterisiert und spezifiziert die Erfindung insbesondere im Zusammenhang mit den Figuren zusätzlich.To avoid these disadvantages and to facilitate assembly of two X-shaped crossing beams, in particular to facilitate the assembly of a rafter with a purlin, the beam connector specified in claim 1 and the use of such a beam connector specified in claim 14 are proposed. Optional, advantageous embodiments of the invention are specified in the dependent claims.

The description additionally characterizes and specifies the invention, in particular in connection with the figures.
Die Erfindung betrifft einen Balkenverbinder zum Verbinden eines ersten Balkens, insbesondere einer Pfette, mit einem zweiten Balken, insbesondere einem Sparren, wobei der zweite Balken den ersten Balken X-förmig kreuzt und der Balkenverbinder einen ersten Abschnitt zur Verbindung mit dem ersten Balken und einen zweiten Abschnitt, welcher an den ersten Abschnitt an einer gemeinsamen ersten Biegung angrenzt, zur Verbindung mit dem zweiten Balken aufweist. Der Balkenverbinder weist zusätzlich einen dritten Abschnitt zur Verbindung mit dem ersten Balken und einen vierten Abschnitt, welcher an den dritten Abschnitt an einer gemeinsamen zweiten Biegung angrenzt, zur Verbindung mit dem zweiten Balken auf. Dabei sind der zweite Abschnitt und der vierte Abschnitt des Balkenverbinders ganz oder teilweise zur satt flächigen Anlage an eine, insbesondere an die gleiche, Balkenseitenwandung des zweiten Balkens ausgebildet. Nach erfolgter Montage liegen damit der zweite Abschnitt und der vierte Abschnitt an der gleichen Balkenseitenwandung des zweiten Balkens, insbesondere des Sparrens an.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.
Durch die Hinzufügung der zusätzlichen Abschnitte wird die Stabilität der Balkenverbindung, insbesondere für Balkenverbindungen im Dachstuhl, bspw. zwischen einem Sparren und einer Pfette, verbessert, wobei der Sparren die Pfette X-förmig kreuzt. Der erfindungsgemäße Balkenverbinder ist besonders geeignet für die Verwendung als Sparren-Pfetten-Anker zum Einsatz im Dachbau. Im weiteren Verlauf der Beschreibung wird meist vereinfacht von Sparren und Pfette gesprochen, wobei "Pfette" jeden ersten Balken und "Sparren" jeden zweiten Balken, nicht nur im Dachbau, unabhängig von dessen Querschnitt einschließt. Anstelle der Pfette kann der Balkenverbinder auch dazu verwendet werden, den Sparren mit einer Betonplatte zu verbinden, sodass der Sparren auf der Betonkante aufliegt. Typischerweise sind die zu verbindenden Balken aus Holz, allerdings kommt grundsätzlich jedes geeignete Material, z.B. auch eine Metallstrebe, in Frage. Unter "angrenzt" kann verstanden werden, dass zwei Abschnitte eine gemeinsame Biegung oder Kante aufweisen, also an einer Biegeachse und/oder Knickachse einander berühren. Der Sparren kann gegenüber der Pfette quasi "senkrecht" angeordnet sein, indem wenigstens eine Sparrenwandung senkrecht zu einer Pfettenwandung verläuft. Das heißt, dass eine Mittelachse oder Balkenkante der Pfette senkrecht zu einer Seitenwandung des Sparrens verläuft. Bspw. bei einer fallenden Traufe kann jedoch auch diese Mittelachse der Pfette oder die Balkenkante der Pfette schräg zu allen Seitenwandungen des Sparrens verlaufen. In diesem Fall würde der Sparren mit einer Kante auf der Kante der Pfette eine Punktauflage ausbilden. Auf einen Sattel bzw. eine Kerve, also einen Einschnitt im Sparren kann durch die Verwendung zusätzlicher Abschnitte am Balkenverbinder verzichtet werden. Dadurch wird der Nachteil vermieden, dass ein solcher Sattel den Balken durch die Reduktion des Balkenquerschnitts unter Umständen schwächen kann, womit insbesondere im Dachbau dann zusätzliche Stabilisierungsmaßnahmen erforderlich sind. Auch der zusätzliche Bearbeitungsschritt des Sparrens für die Herstellung des Sattels entfällt, womit die Montage erleichtert wird. Ein zusätzlicher Sparrennagel kann, muss aber nicht verwendet werden.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. In the further course of the description, 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. Instead of the purlin, 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. in the case of a falling eaves, however, this central axis of the purlin or the beam edge of the purlin can also run obliquely to all side walls of the rafters. In this case 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.
In einer besonders bevorzugten Ausführungsform der Erfindung sind der erste Abschnitt und der dritte Abschnitt des Balkenverbinders zueinander rechtwinklig angeordnet oder schließen einen rechten Winkel ein. Der rechte Winkel entsteht vorzugsweise durch einmaliges oder mehrmaliges Umbiegen eines flachen Blechstücks (Flachblechstücks), sodass zwei Teilstücke des Flachblechstücks die Schenkel des rechten Winkels bilden. Dadurch kann der Balkenverbinder zur Montage formschlüssig an die Pfette mit rechteckigem Querschnitt angelegt werden, sodass die beiden Abschnitte satt flächig an der Pfette anliegen und eine Kante der Pfette vorzugsweise an oder bei der Biegung, also dem Innenraum des rechten Winkels, angeordnet ist. Der erste oder der dritte Abschnitt sind zur oberseitigen Auflage auf der Pfette ausgebildet. Durch die oberseitige Auflage können die senkrechten Dachlasten besser von dem Sparren auf die Pfette übertragen werden, was den Dachstuhl zusätzlich statisch stabilisiert. Ein solcher Balkenverbinder kann damit den Sattel bzw. die Kerve im Sparren ersetzen. Zum Ausgleich von Millimeterabweichungen, die im Dachbau mit Holz oft nicht vollständig vermeidbar sind, kann der erste Abschnitt und/oder der dritte Abschnitt mit einer Schraubzwinge flächig anliegend an die Pfette gedrückt oder gespannt werden. Dies ermöglicht die Verwendung als Sattel-Sparren-Pfetten-Anker, also als Sparren-Pfetten-Anker oder Balkenverbinder mit Sattel für eine Sparren-Pfetten-Verbindung, da der Balkenverbinder den Sattel bereits integriert aufweist. Durch die flächige Auflage auf der Oberseite der Pfette kann der Monteur, auch ggf. ohne die Verwendung von Einschlagzacken, den Balkenverbinder in seiner endgültigen Montageposition auch vor dem Anbringen der Befestigungsmittel (Schrauben, Nägel) "loslassen", ohne dass der Balkenverbinder seine Position verändert oder herunterfällt. Dadurch ist prinzipiell eine Montage mit einer Hand möglich.In a particularly preferred embodiment of the invention, 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. As a result, 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. Due to the top support, the vertical roof loads can be better transferred from the rafters to the purlin, which additionally stabilizes the roof structure statically. Such a beam connector can thus replace the saddle or the peg in the rafters. To compensate for millimeter deviations, which are often not completely avoidable in timber roof construction, 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. Due to the flat support on the top of the purlin, 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.
Vorzugsweise grenzt der erste Abschnitt an den dritten Abschnitt an einer gemeinsamen dritten Biegung an. In anderen Worten sind der erste Abschnitt und der dritte Abschnitt zueinander wie ein Einfachwinkel (vgl.
In einer zusätzlichen Ausführungsform des Balkenverbinders sind der zweite Abschnitt und der vierte Abschnitt ganz oder teilweise, bspw. zur satten Anlage an eine ebene Balkenwandung, in einer Ebene angeordnet. Insbesondere sind der zweite Abschnitt und der vierte Abschnitt ganz oder teilweise, bspw. zur satten oder satt flächigen Anlage an eine Seitenwandung eines Sparrens angeordnet. Dadurch, dass zwei oder mehr Abschnitte des Balkenverbinders die Lasten des Sparrens an der Verbindung aufnehmen, wird die Stabilität weiter verbessert. Bei der Verwendung von zwei Balkenverbindern, also einem links und einem rechts des Sparrens, liegen insgesamt vier flächige Teilstücke an dem Sparren zur Aufnahme der Lasten an. Das schließt ein, dass der zweite Abschnitt und der vierte Abschnitt als Teilbereiche eines durchgehenden Flachblechstücks ausgebildet sind. Das heißt, dass der zweite Abschnitt und der vierte Abschnitt aneinander angrenzen können, ohne zueinander gebogen oder geknickt zu sein. Dies ermöglicht eine Ausbildung der beiden Abschnitte ohne zusätzliche Fertigungsschritte. Alternativ können der zweite Abschnitt und der vierte Abschnitt zueinander bereichsweise mit Abstand ausgebildet sein oder bspw. eine Ausnehmung oder Ausstanzung aufweisen, damit auf dem Sparren angezeichnete Markierungslinien, z.B. Senkelriss oder Waagriss sichtbar bleiben. Diese Ausnehmung oder Ausstanzung kann sich auch auf den ersten Abschnitt und den dritten Abschnitt erstrecken.In an additional embodiment of the beam connector, 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. In particular, 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. This means that 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. As an alternative, 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.
In einer optionalen Weiterbildung des Balkenverbinders sind eine Begrenzungskante des zweiten Abschnitts und eine Begrenzungskante des vierten Abschnitts zueinander rechtwinklig angeordnet oder schließen einen rechten Winkel ein. Durch diese Variante der Erfindung nimmt stets einer der beiden Abschnitte vor allem die vertikalen Dachlasten und einer der beiden Abschnitte vor allem die horizontalen Dachlasten auf. Durch die rechtwinklige Anordnung der beiden Abschnitte können Balkenverbinder in identischer Ausführung sowohl links eines Sparrens, als auch rechts eines Sparrens montiert werden. Dadurch muss der Monteur keine unterschiedlichen Balkenverbinder mehr zur Hand haben. Auch eine Verwechslung der linken und rechten Ausführung ist damit ausgeschlossen, womit die Montage insgesamt deutlich weniger fehleranfällig wird.In an optional further development of the beam connector, 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. With this variant of the invention, 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.
Zusätzlich kann der Balkenverbinder spiegelsymmetrisch bezüglich einer ersten Symmetrieebene und/oder Mittelebene ausgebildet sein. Dadurch wird eine uneingeschränkte Verwendbarkeit eines Balkenverbinders auf beiden Seiten des Sparrens sichergestellt, was die Zahl der notwendigen Bauteile zur Montage eines Dachstuhls reduziert und damit die die Herstellungskosten für die notwendigen Bauteile und damit die Montagekosten senkt. Diese Symmetrie bedeutet insbesondere auch, dass die Flächen des ersten Abschnitts und des dritten Abschnitts, sowie des zweiten und des vierten Abschnitts jeweils zueinander kongruent sind.In addition, 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.
In einer weiteren vorteilhaften Ausführung ist zwischen einer Balkenkante des ersten Balkens und einer unterseitigen Balkenwandung des zweiten Balkens eine linienförmige und/oder punktförmige Berührung und/oder Auflage ausgebildet oder ausbildbar. Dies ist im Dachbau so zu verstehen, dass der Sparren mit einer unterseitigen Begrenzungswandung tangential und/oder schräg auf einer Balkenkante der Pfette aufliegt und sich dabei eine linienförmige Auflage unter Ausbildung einer geraden Linie ausbildet. Im Falle anders ausgeformter Balken (bspw. mit einem runden Querschnitt) oder bei steigenden bzw. fallenden Traufen sind auch punktförmige Auflagen oder Kombinationen aus linienförmigen und punktförmigen Auflagen denkbar. Dies ist auch eine Wirkung daraus, dass auf einen Sattel bzw. eine Kerve verzichtet werden kann.In a further advantageous embodiment, 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. In roof construction, 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. In the case of differently shaped beams (for example with a round cross section) or with rising or falling eaves, 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.
Vorteilhafterweise schließen eine oberseitige Begrenzungswandung des ersten Balkens und eine unterseitige Balkenwandung des zweiten Balkens gemeinsam einen spitzwinkligen Neigungswinkel ein, wobei der Balkenverbinder ein Einstellmittel zur Bestimmung und/oder zur Festlegung des Neigungswinkels aufweist. Im Dachbau schließen somit eine oberseitige Begrenzungswandung der Pfette und eine unterseitige Wandung des Sparrens gemeinsam den spitzwinkligen Neigungswinkel der Dachschräge ein, wobei der Balkenverbinder ein Einstellmittel zur Bestimmung und/oder zur Festlegung der Dachschräge aufweist. Der Neigungswinkel des Sparrens, der mit oder ohne Sattel, an die Pfette angelegt wird, bestimmt am Ende die Dachschräge bzw. die Dachneigung. Die Dachneigung wird immer zum Dach hin gemessen. Wird auf einen Sattel im Sparren verzichtet, bietet eine glatte unterseitige Begrenzungswandung des Sparrens keinerlei Orientierung für ein Anlegen des Sparrens unter Beachtung des vorgegebenen Neigungswinkels. Durch ein Einstellmittel am Balkenverbinder, also ein Hilfsmittel zur Einstellung der Dachschräge, kann diese Orientierung ermöglicht werden. Nach erfolgter Montage kann die tatsächliche Neigung des Sparrens gegenüber der Pfette ebenfalls durch das Einstellmittel bestimmt oder abgelesen werden. Damit ist nach erfolgter Montage auch an jeder Sparren-Pfetten-Verbindung eine baulich integrierte Information über den Neigungswinkel vorhanden und ggf. ablesbar. Dies ermöglicht nachträgliche Kontrollen, womit die Sicherheit und die Qualität der Ausführung deutlich gesteigert werden kann. Montagefehler können frühzeitig erkannt und gegebenenfalls korrigiert werden. Dies ist insbesondere bei nachträglichen Reparatur- und Umbauarbeiten an unübersichtlichen bzw. schwer zugänglichen Orten von Vorteil, wenn lokal eine Bestimmung der Dachneigung ansonsten mit erhöhtem Aufwand verbunden wäre.Advantageously, 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. In the roof construction, 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. If a saddle is not used in the rafters, 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. After installation, the actual inclination of the rafters with respect to the purlin can also be determined or read using the setting means. After installation, 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.
In einer optionalen Weiterbildung weist das Einstellmittel eine oder mehrere gerade Einstellelemente auf dem zweiten Abschnitt und/oder vierten Abschnitt auf. Ein solch gerades Einstellelement kann als Kerbe, Nut, Rille, Vertiefung oder einfach als aufgezeichnete Markierungslinie ausgebildet sein. Die Einstellelemente können durchgehend oder mit Unterbrechungen ausgebildet sein. An ein solches Einstellelement kann die Kante des Sparrens und/oder eine sonstige unterseitige Begrenzungswandung eines zweiten Balkens angelegt und somit anhand der vorgegebenen Dachneigung ausgerichtet werden. Die entsprechenden Einstellelemente können auf beiden Seitenwandungen des zweiten und/oder des vierten Abschnitts angeordnet sein, womit die vielseitige Verwendbarkeit des Balkenverbinders verbessert wird. Die Anordnung der Einstellelemente kann auf beiden Seiten gleich, aber auch unterschiedlich ausgestaltet sein.In an optional development, the setting means has one or more straight setting elements on the second section and / or fourth section. Such 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.
In einer Weiterbildung der Einstellelemente sind zwei oder mehrere Einstellelemente als gerade, radial und/oder strahlenförmig angeordnete Markierungslinien mit einem gemeinsamen Ursprung als Schnittpunkt der Linien ausgebildet. An dem von dem Ursprung beabstandeten Ende einer solchen Linie kann eine Beschriftung und/oder Skala zur Angabe des einzustellenden oder eingestellten Neigungswinkels, insbesondere der einzustellenden oder eingestellten Dachschräge, vorgesehen sein. Für eine uneingeschränkte Austauschbarkeit der Ausführungsformen können zwei Winkelmaße an jedem solchen Ende vorgesehen sein, die sich zueinander auf 90° addieren (bspw. 40° und 50°).In a further development of the setting elements, 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. At the end of such a line spaced from the origin, a label and / or scale can be provided to indicate the angle of inclination to be set or set, in particular the sloping roof to be set or set. For an unlimited interchangeability of the embodiments, two angular dimensions can be provided at each such end, which add up to 90 ° to one another (for example 40 ° and 50 °).
Vorteilhafterweise liegt ein Ursprung der Einstellelemente in einem Verbindungsbereich zwischen dem ersten Abschnitt und dem dritten Abschnitt. Sofern die unterseitige Balkenwandung des Sparrens direkt auf der Balkenkante der Pfette aufliegt, fällt der Ursprung mit dieser Balkenkante der Pfette zusammen bzw. er liegt in dem Innenbereich der vorzugsweise rechtwinkligen Biegung und somit auf der Unterseite des Verbindungsbereichs des ersten und des dritten Abschnitts des Balkenverbinders. Der Ursprung liegt also im Sattel oder auf der Biegeachse der Biegung zwischen den beiden Abschnitten, die an der Pfette anliegen. Damit verlaufen die Einstellelemente quasi von der Balkenkante der Pfette radial bzw. strahlenförmig weg, was eine einfache Orientierung für den Monteur bei der Montage des Sparrens ermöglicht.Advantageously, 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.
Optional bildet der Verbindungsbereich zwischen dem ersten Abschnitt und dem dritten Abschnitt eine linienförmige und/oder punktförmige Berührung und/oder Auflage für den zweiten Balken aus. Anders ausgedrückt bildet der Verbindungsbereich zwischen dem ersten Abschnitt und dem dritten Abschnitt eine linienförmige und/oder punktförmige Berührung und/oder Auflage für den Sparren aus. Der Sparren kann damit auf den beiden Abschnitten, die an der Pfette anliegen, ebenfalls unter Ausbildung einer geraden Linie aufliegen. Der Sparren bildet also nicht mehr mit der Balkenkante der Pfette eine linienförmige und/oder punktförmige Auflage, sondern mit dem Balkenverbinder selbst. Dies ist insbesondere dann von großem Vorteil, wenn an der Pfette kein Platz für eine Montage des ersten und dritten Abschnitts neben dem Sparren vorhanden ist, etwa weil eine Dachgaube vorgesehen ist. Soll in diesem Fall zuerst der Sparren mit dem Balkenverbinder und anschließend der Balkenverbinder mit der Pfette verbunden werden, müssen die Befestigungsmittel (Schrauben, Nägel) durch den Sparren getrieben werden, damit die Befestigungsmittel anschließend durch vorzugsweise vergrößerte Befestigungsöffnungen oder Langlöcher in dem ersten und/oder dritten Abschnitt in Wirkverbindung mit der Pfette gebracht werden können. Hierfür muss der Sparren entsprechend dem Neigungswinkel der Dachschräge vorgebohrt werden. Alternativ können die Teilflächen des Flachblechstücks im Bereich des ersten und/oder der dritten Abschnitts entsprechend vergrößert werden, sodass die Befestigungsöffnungen auch bei montiertem Sparren noch für Befestigungsmittel zugänglich sind. Der Ursprung für die Einstellelemente kann in dieser Ausführungsform je nach gewählter Dicke des Flachblechstücks für den ersten und dritten Abschnitt mit einem Versatz gegenüber der Balkenkante der Pfette angeordnet sein, wobei der Ursprung trotzdem im Außenraum auf der verlängerten Winkelhalbierenden des vorzugsweise rechten Winkels liegt, den der erste und der dritte Abschnitt einschließen. Er liegt damit bspw. oberseitig oder oberhalb auf der Blechkante zwischen dem ersten und dem dritten Abschnitt.Optionally, the connection area between the first section and the third section forms a linear and / or punctiform contact and / or support for the second bar. In other words, 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. In this case, if the rafters are to be connected to the beam connector first and then the beam connector to the purlin, the fasteners (screws, nails) must be driven through the rafters so that the fasteners are then passed through preferably enlarged fastening openings or elongated holes in the first and / or third section can be brought into operative connection with the purlin. For this, the rafters must be pre-drilled according to the angle of inclination of the roof slope. Alternatively, the partial areas of the flat sheet metal piece in the area of the first and / or the third section can be enlarged accordingly, so that the fastening openings are still accessible for fastening means even when the rafters are installed. The origin for the adjusting elements can be arranged in this embodiment, depending on the selected thickness of the flat sheet piece for the first and third sections with an offset relative to the beam edge of the purlin, the origin nevertheless being in the outer space on the extended bisector of the preferably right angle, which the include first and third sections. It thus lies, for example, on the top side or above on the sheet metal edge between the first and the third section.
In einer vorteilhaften Weiterbildung der Erfindung ist für den Balkenverbinder ein fünfter Abschnitt, welcher mit dem ersten Abschnitt verbunden ist und/oder ein sechster Abschnitt, welcher mit dem dritten Abschnitt verbunden ist, zur Verbindung mit dem zweiten Balken, also im Dachbau bspw. mit dem Sparren, vorgesehen. Damit weist ein solcher Balkenverbinder wenigstens einen zusätzlichen Abschnitt, oder noch besser zwei zusätzliche Abschnitte, zur Befestigung am Sparren auf. Dadurch kann die Stabilität der Verbindung zwischen Sparren und Pfette so weit gesteigert werden, dass ein zweiter Balkenverbinder, also bspw. in linker und in rechter Ausführungsvariante, entbehrlich werden. Der Sparren kann damit mit einem einzigen Balkenverbinder an der Pfette befestigt werden.In an advantageous development of the invention, a fifth section, which is connected to the first section and / or a sixth section, which is connected to the third section, is for the beam connector for connection to the second beam, i.e. in the roof structure, for example with the Rafters, provided. Such a beam connector thus has at least one additional section, or even better two additional sections, for attachment to the rafters. As a result, the stability of the connection between rafters and purlin can be increased to such an extent that a second beam connector, for example in the left and in right variant, can be dispensed with. The rafter can be attached to the purlin with a single beam connector.
In einer besonders einfach zu montierenden Ausführungsform der Erfindung bilden der erste Abschnitt, der zweite Abschnitt und der fünfte Abschnitt und/oder der dritte Abschnitt, der vierte Abschnitt und der sechste Abschnitt einen Verbinder mit U-förmigem Profil zur Führung und/oder Aufnahme des zweiten Balkens, also im Dachbau bspw. des Sparrens, zwischen dem zweiten Abschnitt und dem fünften Abschnitt und/oder dem vierten Abschnitt und dem sechsten Abschnitt aus. Der zweite und der fünfte Abschnitt des Balkenverbinders bilden also die Schenkel des U-Profils, während der erste Abschnitt den Mittelbereich des U-Profils darstellt. Zusätzlich oder alternativ dazu bilden der vierte und der sechste Abschnitt des Balkenverbinders die Schenkel eines weiteren U-Profils, während der dritte Abschnitt den Mittelbereich dieses weiteren U-Profils darstellt. Die Mittelbereiche zweier U-Profile sind zueinander vorzugsweise rechtwinklig um eine Biegung eines flachen Blechstücks angeordnet.In a particularly easy-to-assemble embodiment of the invention, the first section, the second section and the fifth section and / or the third section, the fourth section and the sixth section form a connector with a U-shaped profile for guiding and / or receiving the second Beam, so in the roof structure, for example, rafters, between the second section and the fifth section and / or the fourth section and the sixth section. The second and the fifth section of the beam connector thus form the legs of the U-profile, while the first section represents the central region of the U-profile. Additionally or alternatively, the fourth and the sixth section of the beam connector form the legs of a further U-profile, while the third section represents the central region of this further U-profile. The central regions of two U-profiles are preferably arranged at right angles to one another around a bend in a flat piece of sheet metal.
Zusätzlich ist der Balkenverbinder spiegelsymmetrisch bezüglich einer zweiten Symmetrieebene und/oder Mittelebene ausgebildet, wobei die zweite Symmetrieebene und/oder Mittelebene senkrecht zum ersten Abschnitt und/oder zum dritten Abschnitt verläuft. Dadurch bildet sich quasi eine symmetrische Führung und/oder Schiene zur Aufnahme des Sparrens aus, wobei die Schenkel der U-Profile sattflächig an zwei gegenüberliegenden Wandungen des Sparrens anliegen. Der Sparren ist damit von einem einzigen Balkenverbinder gegen ein unbeabsichtigtes seitliches Verrutschen nach beiden Seiten hin begrenzt. Auch für einen Balkenverbinder mit fünf oder sechs Abschnitten können entsprechende Einstellelemente auf beiden Seitenwandungen des zweiten, des vierten, des fünften und/oder des sechsten Abschnitts vorgesehen sein.In addition, the beam connector is mirror-symmetrical with respect to a second plane of symmetry and / or center plane, the second plane of symmetry and / or center plane running perpendicular to the first section and / or the third section. A quasi-symmetrical guide and / or rail for receiving the rafters is thereby formed, the legs of the U-profiles abutting against two opposite walls of the rafters. The rafters are thus limited by a single beam connector against unintentional slipping to both sides. Corresponding setting elements can also be provided on both side walls of the second, fourth, fifth and / or sixth section for a beam connector with five or six sections.
Vorteilhafterweise können an dem Balkenverbinder ein oder mehrere Versteifungselemente, bspw. eine Rippenverstärkung, zwischen zwei angrenzenden Abschnitten angeordnet sein. Dadurch können ein Zurückbiegen und/oder Aufbiegen zweier zueinander verbogener Teilflächen eines Flachblechstücks verhindert und auch sonstige Belastungen durch Biegung und/oder Torsion besser aufgenommen werden. Ferner können alle dem Fachmann bekannten Merkmale, wie sie bei Montageelementen zur Montage eines Dachstuhls typischerweise verwendet werden, dem Balkenverbinder hinzugefügt werden. Insbesondere kann der Balkenverbinder auch einfarbig oder mehrfarbig lackiert gefertigt werden. Neben Versteifungselementen sind da bspw. Einschlagzacken, Montagezinken und/oder Montagestifte zu nennen, die sich beim Anlegen eines Befestigungselements zur Arretierung in das Holz eines Balkens bohren und/oder schieben und damit ein unbeabsichtigtes Verrutschen nach dem Auflegen verhindern oder erschweren.One or more stiffening elements, for example a rib reinforcement, can advantageously be arranged on the beam connector between two adjacent sections. As a result, bending back and / or bending open of two mutually bent partial surfaces of a flat sheet metal piece can be prevented and other loads caused by bending and / or torsion can also be better absorbed. Furthermore, all can the expert known features, as are typically used in assembly elements for assembling a roof structure, are added to the beam connector. In particular, the beam connector can also be made with a single or multi-color finish. In addition to stiffening elements, there are, for example, drive-in prongs, assembly tines and / or assembly pins that drill and / or slide into the wood of a beam when a fastening element is attached for locking and thus prevent or complicate unintentional slipping after hanging up.
Eigenständiger Erfindungsschutz wird ferner beansprucht für eine Verwendung eines Balkenverbinders in einer der zuvor beschriebenen Ausführungen zur Erstellung einer Verbindung zwischen einem Sparren und einer Pfette im Dachbau. Dies schließt insbesondere eine Verbindung ohne Sattelverbindung, d.h. ohne Sattel oder im Kerve im Sparren mit ein. Vielmehr liegt eine ebene durchgehende unterseitige Balkenwandung des Sparrens auf der Pfette oder dem Ballenverbinder auf. Im Falle einer steigenden oder fallenden Traufe liegt bei der Balkenverbindung eine einzelne Kante des Sparrens auf der Pfette auf. Die Pfette kann auch als Betonplatte oder Dachplatte ausgebildet sein.Independent protection of the invention is also claimed for the use of a beam connector in one of the previously described versions for creating a connection between a rafter and a purlin in the roof construction. This particularly includes a connection without a saddle connection, i.e. without a saddle or in a chevron with rafters. Rather, there is a flat, continuous bottom wall of the rafters on the purlin or the bale connector. In the case of rising or falling eaves, a single edge of the rafters lies on the purlin in the beam connection. The purlin can also be designed as a concrete slab or roof slab.
