Definitions

  • the invention relates to a method of constructing a roof for a building, for example in new or repair construction of buildings, as well as to a roof constructed with such a method.
  • Constructing a building roof is typically one of the most essential building construction phases, since thereby is provided i.a. weather protection for building interiors. Accordingly, it functions in the building process as one essential stage of construction in view of which the other building process phases must be correctly scheduled.
  • the construction of a building roof and roof structure may typically take several days. During this period, the previously erected wall structures, on top of which the roof to be constructed is resting, will be exposed to weather and possible water damage, as well as to mold problems subsequently caused thereby.
  • Patent application Fl 20145950 discloses one solution for rapidly providing a weather protection, comprising roof trusses for a roof structure, and a weather protection integrated therewith.
  • the prefabricated roof trusses for a roof structure, along with the weather protection are assembled at a factory for a roof truss package in which the individual roof trusses are disposed side by side in a bundle and the weather protection is attached in a pleated condition on top of the truss bundle.
  • the truss bundle is lifted onto the upper runners of wall structures and unfolded in such a way that the adjacent trusses become locked at a certain distance from each other by means of brace members included in the trusses and at the same time the weather protection unfolds to cover the trusses and the intervening space.
  • the individual trusses are fastened to the upper runners of wall structures.
  • the construction of a roof surface-comprising structure on top of roof trusses nevertheless continues to be a time consuming process, which is further hindered by occupational safety regulations and hazards due to work at height.
  • the present invention provides a rapid method of constructing a roof on top of the load-bearing roof trusses of a roof structure, whereby the time spent for working on the roof, as well as workplace safety problems related thereto, can be effectively minimized.
  • the expedited roof manufacturing process can be utilized in speeding up the overall house building process.
  • the roof is constructed from prefabricated roof panels, which are to be lifted onto roof trusses and comprise a roof surface, and which are fastened to the roof trusses with locking members, thus enabling a rapid final secure fastening of the roof panels in place.
  • a capability of assembling a roof surface structure at construction site in a few hours as opposed to the conventional building of a roof over several days.
  • a capability is provided of tailoring the prefabricated panels to comply with intended applications, as well as of outfitting the same as necessary, for example with solar panels, whereby stages of work to be performed on the roof can be minimized.
  • the method of the invention for building a roof comprises constructing first for an upper part of the building a load-bearing support structure for the roof from roof trusses, on top of said support structure being constructed a roof structure comprising a roof surface, the roof structure comprising a plurality of prefabricated roof panels, said roof panels being hoisted onto the top of roof trusses included in the support structure provided in the upper part of the building and being fastened to the roof trusses, and fastening the roof panels to the roof trusses there is performed by using at least one locking piece, by displacing said locking piece with respect to a roof truss and/or a roof panel present on top of said roof truss in a plane substantially parallel to a junction surface of the roof truss and/or the roof panel, or by displacing a roof panel with respect to the locking piece in a direction defined by the locking piece's longitudinal center axis, there is achieved a final attachment and locking of the roof panel in place with respect to the roof
  • roof truss refers in this context to a framework or roof truss of lat- tice type design, which constitutes a roof structure bearing the load from top of the building's walls.
  • the locking piece is a substantially plate-like object provided with asymmetric slots, the locking between a roof truss and a roof panel being achieved by way of said asymmetric slots.
  • the locking piece can be for example a gutter, which is present in a roof truss mounting rail or in a panel fastening member, and which attaches to a counterpart's matching locking formation as the panel is moved.
  • the locking piece may also be for example a locking pin or protrusion, which is present in a truss or in a roof panel fastening surface, and which finds its way and locks to a counter- part's locking formation as the roof panel is lowered directly in place.
  • the locking piece is a protrusion type object, which is fixed to a top surface of the roof truss directly or by way of an adapter, and the roof panel locking to said locking piece in a form closed manner by lowering the roof panel on top of the roof truss and the locking piece.
  • the locking piece can be for example a pin type protrusion whose base portion is formed with a narrowing for establishing a form closed locking.
  • the load bearing support structure for a roof is assembled by lifting a prefabricated roof truss bundle on top of the upper runners of a building's wall structures, the roof truss bundle is unfolded by pulling on a truss included in the bundle, whereby the bundle's roof trusses are locked by way of brace elements included in the bundle at a predetermined distance relative to each other, and with the bundle completely unfolded and the roof trusses located at final positions thereof, the roof trusses will be fas- tened to the upper runners of a building's wall structures.
  • the roof panel is formed with at least one block or section, which attaches to the roof truss and by way of which the fastening of a roof panel to a roof truss is implemented.
  • a section can be for example a rail type adapter included in the roof panel or a recess formed in the roof panel wherein settles the top surface area of a roof truss.
  • the roof panel is made up of a frame or framework and a part or section constituting the roof surface.
  • the roof panel can also be designed for example as box-type structure.
  • the roof panels are not load-bearing members of the roof structure in the direction of trusses.
  • the roof panels must have a required load bearing capacity in the intervening area between roof trusses.
  • the building's roof is a pitched roof, a mono-pitch roof, a hip roof, a mansard roof or a broken-pitch roof.
  • the invention relates also to a roof and a roof structure built with the method.
