Definitions

  • the present invention generally relates to the transportation of structural members for use in building construction and in particular to roof truss systems and floor truss systems.
  • a truss is a generally rigid frame member designed to support a structure, such as a roof or a floor. Trusses come in many shapes and sizes for a variety of applications.
  • Roof trusses for commercial and residential buildings are typically prefabricated using wooden beams and metal joiner plates. Such prefabricated structures are large and heavy and must be shipped from the factory to the building site in small numbers on a large truck. The handling of theses trusses is difficult and present disadvantages such as time consuming manipulation, difficulty to handle the trusses and expensive costs which increase overall building construction costs.
  • An alternative is to ship prefabricated roof sections but with major disadvantage such as expansive moving cost and difficulty to manipulate the prefabricated roof sections.
  • the present invention is realized by generally providing a support device for truss system comprising a supporting structure comprising a pair of first members; a plurality of transversal members being transversal to the first member; at least two receiving members extending from the transversal members, the receiving members comprising a plurality of recess adapted to receive trusses, the recesses being distanced at a predetermined distance.
  • the present invention also provides a method of constructing and moving a truss system using a support device for truss system, the support device comprising a supporting structure on which extend at least two receiving members, the receiving members comprising a plurality recesses adapted to received trusses, the method comprising the steps of placing the support device in front of trusses; placing the trusses in the recesses; constructing the truss system; moving the truss system supported by the support device on the top surface of walls of a building; removing the support device from the truss system.
