Definitions

  • Photovoltaic systems are gaining more and more importance due to the climate-related need to develop alternatives to fossil energy production on a larger scale. In particular on pitched roofs with classic roof construction, this results in problems that result from wind and snow load-related loads of mounting systems for photovoltaic modules.
  • roof brackets As important connections between usually composed of profiles stretcher and the roof structure.
  • Conventional roof brackets consist of support brackets which are screwed onto the counter battens or directly on the rafters and U-shaped arms attached thereto, which are guided through the roof skin to the outside, in the case of roofs with roof tiles covering between two roof tile rows.
  • the object of the invention is therefore to provide a roof rack ready that best protects the roof construction and at the same time has all the structural features of a roof rack, which bears the weight of the photovoltaic modules in conjunction with strong wind and / or snow loads dimensionally stable.
  • the construction of the support bracket it should be designed so that recesses are positioned for all connecting means for fastening the support bracket to the roof structure below the roof within the area enclosed by the stabilizing part beyond its inherent stability stabilizing portion of the support bracket to exclude weakening zones that arise when such Recesses are arranged outside a region encompassed by such a stabilization part in an area to be regarded as merely attached to this part.
  • the roof rack presented here has a designed for high loads support bracket with a support, wherein the support supports the mounting plate for mounting on the counter battens and the support plate to which the boom is struck against each other.
  • this support is arranged in the lateral edge region of the support bracket, as close as possible to the stop of the boom. It is particularly advantageous and stabilizing when the support angle assumes the shape of an at least partially closed box, wherein the legs of the support angle have the shape of a curve formed by bending, the preferably enclose wall-shaped support in its lateral basic shape and the support angle has a support wall on both sides.
  • An important aspect of the invention is the interaction of the described inventive construction of the support bracket with support of the legs against each other with the eccentric position of the boom on the one hand and an additional support of the mounting plate of the support bracket against the counter battens by means of an additional support bracket on the other hand, the below Boom position is arranged on the mounting plate of the support bracket and forms a positive connection after mounting with one side of the counter batten.
  • the described the stability of the overall construction endangering tipping moment is intercepted and introduced into the side surface of the counter batten.
  • the support bracket has an operatively connected to the mounting plate of the support bracket, arranged substantially parallel to this base leg and a support leg, wherein the apex of the support bracket is arranged substantially orthogonal to the apex of the support bracket.
  • the support angle preferably has a triangular cross-section and is supported by a shoulder on a side surface of the counter-battens.
  • several embodiments of the support bracket are advantageous. So can be completely dispensed with the shoulder with the result that the support bracket is supported only with its obliquely extending to the counter-blade leg on the side surface.
  • the supernatant of the rafter next to the side surface of the counter batten can also serve as a basis for an introduction of force via the support bracket in the roof construction.
  • the support bracket is then designed so that at the end of its supporting leg a protruding from the counter batten foot is formed.
  • the supporting leg can have a tongue which can be pushed between the counter batten and the rafters instead of the foot at its end.
  • the insertion of the tongue must be made during installation with appropriate tools to avoid injury to the roof liner, which usually runs between counter battens and rafters.
  • a good way of stabilizing the support angle is the lateral attachment of a support wall, which has a form-fitting edge with the side surface of the counter lath.
  • the frictional engagement between the base leg of the support bracket and counter batten is reinforced by a toothing on the underside of the base leg.
  • the support bracket is thereby mountable without additional fasteners.
  • the end of the support leg or his shoulder may advantageously have teeth or other pointed elevations to increase the frictional engagement.
  • Fig. 1 shows a perspective view of the overall construction of the roof holder (1), which illustrates the advantageous interaction of the components of an embodiment of the roof holder (1) according to the invention.
  • the support bracket (2) here has a mounting plate (4) with which the support bracket (2) is mounted transversely on the counter battens. Between counter-battens (not shown) and mounting plate (4) is in the illustrated embodiment, the base leg (13) of the support bracket (9), which as well as by means of its stop (26) eccentrically on the support plate (5) of the support bracket (2) attached by screw boom (3) to the overall construction of the roof holder (1) according to the invention belongs.
  • the cantilever (3) has substantially the shape of a Us, the one of the stop (26) opening out first leg (25), a web (29) and an opening in an angled tongue (28) second Leg (27) is formed, wherein the tongue (28) is provided for the load with the photovoltaic modules supporting frame via possible further connecting components.
  • the boom (3) has a rounded edge (30) in the area closest to the roof cladding in the assembled and loaded condition, which reduces the risk of damage in contact with the roof cladding. Not shown is an additional curvature of the relative to the U-shape outer surface of the second leg (27), which additionally stabilizes the boom against deformation forces.
  • the support angle (2) here has two walls as supports (6) which support the mounting plate (4) effectively against the retaining plate (5) and protect the support bracket (2) against deformation under load.
  • the supports (6) are statically advantageously shaped so that the support plate (5), mounting plate (4), apex (16) of the angle formed by these ( ⁇ ) and the respective wall-shaped support (6) in the cross section of the support bracket ( 2) bounded area is not smaller than one-fifth of the area defined in the cross-section of the support angle (2) by the vertex of the angle ( ⁇ ) and the crest-facing ends (10) of the holding (10a) and mounting plate (10b).
  • the longest edge (12) of the apex (16) of the angle ( ⁇ ) opposite edges (11) of the wall-shaped support (6) extends substantially in a straight line and thus optimally clamps the possible force triangle.
  • Fig. 2 to Fig. 7 show different, resulting from the dependent claims embodiments of the support bracket (9), wherein Fig. 3 shows for illustration also counter battens and rafters. The meaning of the figuring used there arises from the claims.
