Reinforced concrete monocoque roof construction method

A method for constructing a roof, the roof being intended for a building having a rigid peripheral enclosure, the method comprising:

• making a formwork configured to support the roof while it is made and to allow a slab to be poured,
• making a bearing frame configured to ensure mechanical strength of the roof and connect the roof to the building accommodating the roof,
• pouring the slab ensuring a function of binder material, said slab being configured to transfer mechanical loads within the bearing frame,
• making an external girdling, comprising a cornice, connecting the roof to the building by girdling both a portion of an external face of the peripheral enclosure of the building and a portion of the bearing frame attached to the building, to increase the tearing strength of said roof,
• wherein making the bearing frame comprises:
• making a main frame, comprising a set of metal or synthetic reinforcements, configured to ensure spatial delimitation of the roof and connect the roof to the building and to enhance mechanical strength of the roof,
• making a secondary frame, said secondary frame being configured to increase the strength of the main frame and to receive the slab, and
• wherein the main frame comprises:
• wall tie reinforcements connected to corresponding reinforcements extending out of a wall of the building to which the roof is connected;
• and
• a welded mesh connected to the wall tie reinforcements, the welded mesh located above the secondary frame;
• and
• the secondary frame comprises:
• floor beams located underneath the wall tie reinforcements and the welded mesh, the floor beams being configured to rest on the wall of the building and be temporarily supported by respective struts during a construction phase of the roof;
• and
• spacer elements located in between and snap-fitted to the floor beams.
