b01 - Construction design RS02

Introduction. 

The present guideline seeks to describe the main components and the general installation procedure of the BIPV roofing shingle module designed for the Belgian (Mons) demo site within the frame of the BFIRST project. Nevertheless, the components, materials and their installation process may vary in different cases, thus the information provided in this document should be handled with care, adjusting the installation with regard to the existing roof composition in each case. The aim of this guideline is not focused on the installation process of the BIPV modules, but the construction process of the substructure needed to install them.

Construction background.

The roofing substructure is composed by an insulation material, a set of wooden vertical profiles and a metallic construction support system where the BIPV roofing shingles are installed.
A schematic overview of the construction is given next:

Main roof structure with FJI Beams and cover with a layer of CELIT 4D.

Additional wood bats attached to the CELIT 4D on top of the FJI beams
and after that ALUVER (vertical) and gutters profiles placed on the wood beams

ALUTEC FL (horizontal) and final roofing shingles (BIPV modules)

Installation of the vertical profiles over the wooden beams

  • Omega profiles are placed in between two roofing shingles in order to collect the rain water that may flow in the space existing between them.
  • Creotecc ALUVER profiles are used to support the horizontal profiles (ALUTEC FL).

 

Omega profiles

The omega profiles are manufactured on demand by the company Facozinc based in Gilly (Belgium).

Vertical supporting profile (ALUVER)

The ALUVER profiles from the company Creotecc are placed in the center of each panel in order to support the ALUTEC FL horizontal profiles.

Installation of the horizontal profiles

Start at the lower end of the module array. Place the ALUTEC insertion rail horizontally on the ALUVER mounting rail. Ensure that the entire width of the lowest ALUTEC rail lies correctly on the ALUVER rail.

 

Fit the pre-assembled retaining clips to the upper fastening flange of the ALUTEC rails. When the head of the slot screw lies in the slot, turn the nut 90° clockwise to lock the head of the screw and then tighten the nut to a torque of 25 Nm. Make sure that the head of the slot screw is in the “locked” position before tightening the nut.

 

When finished, check that the ALUTEC rails run straight and level and that they are at right angles to the ALUVER rails. Subsequent corrections are then more difficult to perform than at this point in the installation process.

 

Use the assembling jig to position the upper of the two ALUTEC insertion rails so that a gap exists between the two rails having a clearance W = module length (in mm) + 10 mm.

It is also possible to work with the repeated spacing dimension S and mark the position of the upper rail or the upper retaining clip, where S = module length (in mm) + 12 mm.
