Definitions
- a critical component of the mounting systems is the connection between the profile rail scaffolds with which the photovoltaic modules are usually underlaid and supported, and the roof structure below the roof skin.
- These connection components are so-called roof holders, which in turn have to be attached to the roof structure carrier and a held by this, usually U-shaped boom. The boom is guided through the roof, usually between individual tile rows.
- Fig. 1 of the named document also shows the conventional structural features with respect to the carrier.
- the object of the present invention is to provide a carrier of significantly increased stability, the same material properties and thicknesses and the same shape, material properties and strengths of the components carried by him due to constructive features against maximum compared to the prior art Loads of dead weight of the mounting system to be supported as well as wind and snow load is resistant to bending and torsion and remains dimensionally stable.
- the construction of the carrier is intended to be such that recesses for all connection means for fastening the carrier to the roof construction are positioned below the roof skin within the area of the carrier encompassed by the stabilizing part anchoring the basic angle beyond its intrinsic stability in order to exclude weakening zones which are located result if such recesses are arranged outside a region encompassed by such a stabilization part in an area which is to be regarded as merely attached to this part.
- object of the invention is to provide an eccentric mounting option of the boom to the forces acting on the carrier to the roof structure fastening means, usually screws, and the over the boom in the center of counter battens or Rafter-fixed carrier are passed, which in turn acts on the fastening means to convert from a torque in a proportional tilting moment, so as to stabilize the attachment of the support on the roof structure under load. It is therefore also part of the object to substantially prevent torsions around an axis running through the carrier and essentially at right angles to the design of the cantilever, even under strong force, and the ideal construct of an otherwise closed box which is sufficiently open only at the top for mounting purposes get as close as possible.
- an eccentric mounting of the arm in conjunction with a support according to claim 1 would lead to a reduced deformability of the support member and the fastener.
- the eccentric mounting of the cantilever would have the advantage that a displacement of the mounting position of the cantilever relative to that of the girder would allow a narrower and thus material-saving design of the girder, since the cantilever could be positioned above the concave curvature of a tile due to the offset, which could be achieved with centered boom only by a significant broadening of the carrier.
- the carrier according to the invention has at least one holding element for the boom and at least one fastening element for attachment to the roof structure, which are arranged at a fixed angle, usually rectangular, to each other.
- the increased stability of the carrier according to the invention is based on the fact that a rod-shaped support together with the edges of the planar holding and fastening elements spans a triangle, wherein the support rod as far as possible from the vertex of the angle formed by holding and fastening element points directly or indirectly connects and such a bending or torsional force induced deformation of the carrier, which would lead to a change in the distance of the connection points from each other, effectively prevented.
- More stability than a support rod provides the use of a support wall, which need not necessarily be triangular, but for reasons of material savings, however, apart from possible modifications to the edges, advantageously has a substantially triangular basic shape.
- a support wall with rectangular or other basic shape laterally with the angle of fastening and retaining element of the carrier.
- the use of retaining walls has the advantage that they have flatter shapes compared to support rods and can be produced less consuming.
- the boom When centered on counter battens or rafters mounted carrier the boom are advantageously mounted eccentrically in the lateral edge region of the support member.
- the support wall or rod is arranged to make the best possible use of the stabilizing effect of the support.
- two supports per carrier have proven to be advantageous, since during assembly It can be decided on site on which side of the carrier the attachment of the boom is optimal.
- edges which have the shape by bending rounded edges, advantageously comprise the support in order to minimize the risk of injury from sharp, protruding edges during assembly.
- a further increase in stability is achieved by protuberances in the surface of the retaining element. It has proved to be advantageous, also referred to as a mirror, surface offset from the mounting surface of the retaining element.
- the carrier in several parts, for example by holding element and fastener are held together at the apex of the angle formed by them by a Verbidungs Fantasy. They may also overlap at the apex and be bolted together or otherwise connected. For prokukomsökonomischen reasons, however, it is advantageous to manufacture holding and fastening element in one piece.
- At least one material recess is provided for the attachment of the arm on the holding element, which is arranged as close as possible to the position of the support to allow the advantageous eccentric attachment of the arm, but at least in the support-side half of the surface of the support member between Support and outer edge of the mounting surface of the support member, where appropriate, the larger of the two surfaces on the left and right of the support is based.
- a recess here are continuous holes or even depressions within a surface to understand, while recesses, as a special form of recesses, only holes designate holes. Both are suitable to serve as holding possibilities for the boom on the holding element.
- the holding element in the vicinity of the lateral Outer margins and the support has a parallel to the support extending slot in which the boom can engage with a nose torsionsmindernd.
- the reverse variant, in which the holding element has an advantageously nose-shaped elevation for positive engagement in the boom is of course possible.
- elongated holes in the side area of the holding element can serve to attach the boom in different positions along the slot.
- Fig. 1 shows a carrier (1) according to the invention in cross section. It has a holding element (2) and a fastening element (3) which are connected to one another by a support (4) and are arranged at an angle ⁇ , which is 90 ° to one another here.
- a support (4) in this embodiment, a support wall (5) is used, the material recesses (6) and both to the fixed by the fastening element (3) leg of the angle ⁇ parallel edge (7) and one to the by the holding element (2) fixed leg of the angle ⁇ parallel edge (8).
- the fastening element (3) has the shape of at least one rounding caused by bending (9), as well as the holding element (2) has such a curve (10).
- fastener (3) and support wall (5) consist of one piece, which is preferably made of stainless steel or higher-strength materials such as fine grain steel. Of course, depending on the predicted load, other materials, such as galvanized structural steel, extruded aluminum, die-cast aluminum, copper or alloys of the materials mentioned, can be used.
- the embodiment also has a rounding (11).
- the material protuberance (12) of the retaining element which in this case is implemented as a planar offset (13, FIG.
- the longest edge (19) of the apex of the angle ( ⁇ ) opposite edges (18) of the wall (5) in a straight line at least approximately made in a straight line to realize a maximum tension triangle through the support.
- Fig. 2 shows the holding element (2) in the plan view.
- the illustrated preferred embodiment has a running as a slot material recess (14), which is designed as a material recess (15) in the longitudinal direction parallel to the vertical course of the support wall (5) and thus offers the possibility to receive the nose of a boom.
- the material recess (15) is positioned in the support-side half of the largest surface segment regardless of further recesses between the support (4) and outer edge (16) of the holding element (2) and is such that the material recess (15) an eccentric recording of the nose of a Boom allows.
- Fig. 3 shows the fastener (3) in the plan.
- the illustrated embodiment has material recesses (17) in the mounting surface of the fastener (3), which serve as a mounting option for screws or other suitable fastening means.
