Description

FIELD OF INVENTION The present invention relates generally to constructions. EARLIER ART We know of the state of the art of constructions comprising a wooden ceiling frame and a wooden floor frame connected to each other by uprights. To be able to lift the structure, in particular to be able to move it with the help of a crane, it is known to weld lifting parts, such as rings, which extend above the uprights, to which slings can be attached. However, welding lifting components above the uprights can lead to several drawbacks, including increased bulk, which exposes the structure to a risk of impact during transport. These lifting components can also interfere with the stacking of two building modules at the uprights of those modules. Furthermore, it is desirable to ensure the structure is properly sealed between its departure from the factory and its installation on site before final completion. To this end, it is common practice to cover the ceiling frame with a waterproofing membrane, such as EPDM. However, the presence of lifting equipment can hinder the proper installation of the membrane and thus compromise the seal. Furthermore, there is a risk of structural damage during lifting, particularly if the loads are improperly distributed within the structure. To mitigate this risk, it is known to use a lifting beam with the crane. which allows the slings to be oriented vertically to obtain vertical pulling forces. However, the use of such a lifting accessory complicates the lifting operation and requires that this accessory be available on site. The documents US2008/178551 A1 And FR2951213A1 each disclose a modular construction comprising all the features of the preamble of claim 1. The present invention aims to propose a new construction and a corresponding manufacturing process that makes it possible to overcome at least partially all or part of the problems described above. SUMMARY OF THE INVENTION To this end, a construction, preferably modular, is proposed, comprising: a floor frame comprising wooden stringers and crossbeams; a ceiling frame comprising wooden stringers and crossbeams; metal uprights connecting the floor frame to the ceiling frame, and, for each upright, a connection system allowing the upright to be connected to a longitudinal member of the ceiling frame and to a cross member of said frame; characterized in that the connection system comprises: a first assembly hardware system which includes: a connecting wing to a spar of the ceiling frame, said wing having a fixing portion attached to said spar and an assembly portion extending along the axis of the spar projecting from the end face of the spar; and a connecting wing to a cross member of the ceiling frame, said wing having a fixing part attached to said cross member and an assembly part which extends along the axis of said cross member projecting from the end face of the cross member; the assembly part of at least one of the wings, called the lifting wing, of the first assembly fitting system having a cutout, and the first assembly fitting system comprising a connecting piece positioned in the cutout, the connecting piece, called the threaded connecting piece, having a threaded hole in which a lifting piece, such as a ring, is suitable for screwing to be attached to said connecting piece and unscrewing to be removed, the top of the connecting piece being located at a height less than or equal to that of the top face of the spar or cross member to which the lifting wing is attached; a second assembly fitting system fixed, preferably welded, to the upright comprising a first assembly wing riveted with the assembly part of the connecting wing to the longeron, and a second assembly wing riveted with the assembly part of the connecting wing to the cross member. This results in a structure with screw-in areas for lifting components, used for lifting the structure, formed from parts that also serve to connect the uprights to the ceiling frame. Each of these screw-in areas is created through the interaction of the threaded connecting piece, also called a threaded block, and the cutout in at least one flange of a fitting system that allows the assembly of an upright to the ceiling frame. Positioning a threaded connecting piece in a cutout of the fitting system wing so as not to protrude beyond the height of the top face of each spar or cross member of the ceiling frame allows the ceiling frame to be covered by a sealing membrane, which has orifices positioned opposite the threaded orifices of the threaded connecting pieces, to ensure the sealing of the construction, without being hindered by protruding elements, such as lifting parts, which can nevertheless be screwed (and unscrewed to be removed) into the threaded connecting pieces, through the orifices of the membrane, without impacting the correct positioning of the sealing membrane. In particular, the membrane can be reliably fixed, preferably by gluing, to the upper face of the beam (
