CONSTRUCTION, PREFERABLY MODULAR, WITH A WOODEN CEILING FRAME AND A WOODEN FLOOR FRAME

Description

FIELD OF INVENTION

[0001] The present invention relates generally to constructions. EARLIER ART

[0002] 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.

[0003] 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.

[0004] 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.

[0005] 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.

[0006] Furthermore, there is a risk of damage to the building's structure during lifting, particularly in the event of improper load distribution within the structure during the lifting process. 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 tensile forces. However, the use of such a lifting accessory complicates the lifting operation and requires that the accessory be available at the lifting site. Documents US2008 / 178551 A1 and FR2951213A1 each disclose a modular construction comprising all the features of the preamble to claim 1.

[0007] 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

[0008] 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 for connecting the upright to a stringer of the ceiling frame and to a crossbeam of said frame; characterized in that the connection system comprises: a first assembly fitting system which includes: a connecting flange to a stringer of the ceiling frame, said flange having a fixing portion attached to said stringer and an assembly portion which extends along the axis of the stringer projecting from the end face of the stringer; and a connecting flange to a crossbeam of the ceiling frame, said flange having a fixing portion attached to said crossbeam and an assembly portion which extends along the axis of said crossbeam projecting from the end face of the crossbeam;the assembly portion 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 fixed 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 upper face of the longeron or cross member to which the lifting wing is fixed; a second assembly fitting system fixed, preferably welded, to the upright comprising a first assembly wing riveted to the assembly portion of the connecting wing to the longeron, and a second assembly wing riveted to the assembly portion of the connecting wing to the cross member.

[0009] 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.

[0010] 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.

[0011] In particular, the membrane can be reliably fixed, preferably by gluing, to the upper face of the beam (strip or cross member) of the ceiling frame to which the flange of the fitting system that carries the threaded connecting piece is attached, and preferably also to a top plate that covers the threaded connecting piece. In one embodiment, the membrane is also fixed, preferably by gluing, to the upper face (edge) of a riser, for example made of wood, such as laminated wood, fitted to the other beam (cross member or strip) to which a flange of said ceiling frame fitting system is attached, so as to obtain an upper face (edge) of the membrane application located at substantially the same height as the upper face of the beam (strip or cross member) to which the flange of the fitting system that carries the threaded connecting piece is attached.According to one embodiment, the membrane also covers the top of the uprights (posts).

[0012] Each threaded connecting piece not only allows a lifting piece to be screwed in, but also allows the lifting forces to be transmitted to the corresponding upright (post) and to the ceiling frame by coupling, preferably by welding, of the threaded connecting piece with the corresponding wing of the fitting system which is itself fixed to the ceiling frame by its fixing part and to the upright by riveting to another fitting system welded to the upright.

[0013] The use of metal uprights combined with wooden ceiling and floor frames provides a good weight / rigidity ratio for the construction, while the special fitting system used to connect an upright to a frame allows for good load transfer and enables reliable lifting of the structure.

[0014] Thanks to the specific design of the fitting systems attached to the ceiling frame beams, the lifting forces applied to the lifting components can be absorbed by the fitting systems and transmitted to the ceiling frame uprights and beams (stringers and / or crossbeams) via threaded connecting pieces. These connecting pieces not only receive the lifting components but are also each attached to a flange of a fitting system, which is itself fixed to an upright (by riveting to a flange of another fitting system attached to the upright). Preferably, each threaded connecting piece is also fixed, for example by welding, to the top plate attached to a beam, such as a stringer, of the ceiling frame.

[0015] Providing for the riveting of the wings of the upper fitting system of each upright to the fitting system fixed to the ceiling frame (and similarly a riveting of the wings of the lower fitting system of each upright to the fitting system fixed to the floor frame) allows, prior to the riveting operation, for the galvanizing of the entire upright and its fitting systems after fixing, preferably by welding, said fitting systems to the upright.

[0016] Using metal flanges, preferably steel, for riveting between metal uprights and wooden frames also reduces the number of fasteners required compared to screwing the wooden frame beams directly onto upright connectors. The number of fasteners needed to withstand the high loads would be very large, resulting in a screwing time incompatible with mass production. Riveting with horizontal axis rivets is much faster and more ergonomic.

[0017] According to a preferred embodiment, the use of fittings whose webs (fixing parts) are aligned with the longitudinal axis of the beams (longers or crossbeams) in which they are engaged allows for a lifting force axis that coincides with the geometric longitudinal axis of the ceiling frame beams, which limits the presence of "parasitic" moments to be mechanically resisted.

[0018] Screwing each lifting component, such as a lifting ring, into a corresponding threaded connecting piece allows the structure to be lifted for placement on a transport vehicle or for installation on site. Each lifting component can then be unscrewed and removed after lifting, allowing for transport of the structure with a reduced risk of damage, or after installation on site when lifting is no longer required.

[0019] The construction may also include one or more of the following features taken in any technically permissible combination.

[0020] According to one embodiment, the cut opens onto an upper edge of the lifting wing in which said cut is made.

[0021] According to one embodiment, the threaded hole of the connecting piece is a hole, preferably blind, open towards the top of the structure (i.e. in the opposite direction to the floor frame, preferably vertically).

[0022] According to one embodiment, the first assembly fitting system includes a metal plate, preferably elongated, called the top plate, which is fixed, preferably by welding, to the lifting wing, on at least a part of the upper edge of the wing extending perpendicularly to said lifting wing, said top plate being fixed to the top of the spar or cross member of the ceiling frame, to which or on which the lifting wing is fixed.

[0023] In one embodiment, the upper plate has a portion that covers the connecting piece (preferably welded to said connecting piece), said portion of the upper plate having an opening located opposite the tapped opening of the tapped connecting piece to allow the lifting piece to be screwed into the connecting piece through the upper plate. In particular, said portion of the upper plate that covers the connecting piece extends beyond the side member or cross member.

[0024] According to one embodiment, the construction includes a sealing membrane which covers the ceiling frame by being fixed, for example by gluing, to the upper face of the longitudinal or cross member, to which or to which the lifting wing is fixed, and also covering the connecting piece, preferably by being fixed for example by gluing to the upper base, the sealing membrane having an opening positioned opposite the tapped hole to allow the lifting piece to be screwed into the connecting piece through the sealing membrane.

[0025] Advantageously, the membrane is fixed, preferably by gluing, to each of the beams (longitudinal or crossbeam), or beam extension, which forms the frame of the ceiling frame.

[0026] Advantageously, the waterproofing membrane has drooping edges on the upper longitudinal and lateral sides of the building's ceiling frame.

[0027] In particular, the sealing membrane has, for each threaded connecting piece, preferably welded to a top plate, an opening located opposite the threaded hole provided in the connecting piece, to allow the screwing of a lifting piece into the threaded hole of the corresponding connecting piece, by passing through the corresponding opening provided in the sealing membrane.

[0028] According to one embodiment, each fastening part of the first assembly fitting system is engaged in a slot formed in the corresponding side member or cross member, each fastening part being fixed to said side member or cross member by fastening elements, such as screws or pins, extending transversely inside the side member or cross member and passing through said fastening part.

[0029] According to one embodiment, the wing of the second assembly fitting system which is riveted to the lifting wing of the first assembly fitting system has an upper edge which extends below or flush with the bottom of the cut-out in said lifting wing.

[0030] According to one embodiment, the threaded connecting piece is welded to at least one part, preferably each, of the edges of the cut.

[0031] In one embodiment, the upper flange is attached to the longeron by fasteners, such as screws, extending vertically inside the longeron or crossmember and passing through the flange, and preferably attached to the lifting wing, for example, by weld beads along the upper edge of the wing, advantageously on each side of the wing. Advantageously, the upper flange is also welded to the upper edge of the wing attachment point. In a particular aspect, the upper flange is pre-assembled to the wing attachment point by male and female elements, such as tabs projecting from the upper edge of the wing attachment point and inserted into slots formed in the upper flange.

[0032] The threaded connecting piece can extend through the cutout made in the lifting wing on either side of the wing.

[0033] According to one embodiment, the threaded connecting piece has a cross-section with a shape complementary to the cutout (made in the lifting wing).

[0034] According to one embodiment, the threaded connecting piece and the cutout have shapes which, in the inserted state of the threaded connecting piece laterally in the cutout of the lifting wing, oppose the exit of the threaded connecting piece through an open upper edge of the cutout.

[0035] According to one embodiment, the threaded connecting piece has an inverted trapezoidal cross-section.

[0036] According to one embodiment, the threaded connecting piece has a parallelepiped shape.

[0037] According to one embodiment, the wings of the second assembly fitting system are welded onto two adjacent faces of the upright.

[0038] According to one embodiment, each wing of the second assembly fitting system extends orthogonally to the face of the upright to which it is fixed, and parallel to the longitudinal axis of the upright.

[0039] According to one embodiment, each assembly part of the first assembly fitting system extends in projection from one end of the side member or cross member to which it is fixed, being, in view from above of said side member or cross member, centered on the longitudinal central axis of said side member or cross member.

[0040] According to one embodiment, each fastening part of the first assembly fitting system is, in top view of the spar or cross member to which the corresponding wing assembly part is attached, centered on the longitudinal central axis of said spar or cross member.

[0041] According to one embodiment, each metal upright is a hollow post.

[0042] According to one embodiment, the construction also includes, for each upright, a lower connection system for connecting the upright to a floor frame member and to a cross member of said frame; the lower connection system comprising a first assembly fitting system which includes: a connecting flange to the upright having a fixing part attached to said floor frame member and an assembly part of said upright which extends along the axis of the upright projecting from the end face of the upright; a connecting flange to the cross member having a fixing part attached to the floor frame cross member and an assembly part which extends along the axis of the cross member projecting from the end face of the cross member;the lower connection system also comprising a second assembly fitting system fixed, preferably welded, to the upright, and comprising: a first assembly wing riveted with the assembly part of said floor frame longitudinal member, and a second assembly wing riveted with the assembly part of the floor frame cross member.

DETAILED DESCRIPTION

[0049] Embodiments are described below with reference to the accompanying drawings. Similar numbers refer to similar features in all drawings. However, the invention can be implemented in many different forms and should not be construed as being limited to the embodiments shown here. The scope of the invention is defined by the accompanying claims.

[0050] A reference throughout the specification to "an embodiment" means that a particular feature, structure, or characteristic described in relation to an embodiment is included in at least one embodiment of the present invention. Thus, the appearance of the phrase "in an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0051] With reference to the figures, a construction 1 is proposed which includes a floor frame 2 and a ceiling frame 3 made of wood, as well as metal uprights 4 connecting the floor frame 2 and the ceiling frame 3 together.

[0052] The construction described below can be installed on site permanently or in a demountable manner, for example as part of a rental agreement.

[0053] Preferably, the construction is a modular construction. The described modular construction can be assembled with other identical or similar modular constructions by juxtaposition and / or superposition to form, for example, office buildings, residential buildings and, more generally, any type of public access building (ERP).

[0054] In the following description, the terms top, bottom, upper, lower, vertical or horizontal, are considered by reference to an assembled state of the construction which rests on a horizontal ground, with the uprights extending vertically. Amounts

[0055] Preferably, the 4 metal uprights are hollow posts, which allows rainwater to flow through the posts.

[0056] The use of metal posts, preferably made of steel, hollow allows to limit the amount of material used, and facilitates the operation of assembling the construction thanks to the wings fixed, preferably welded, to each post as explained below.

[0057] According to one embodiment, each post 4 has a closed contour section which may also have a local opening, such as the opening 47 shown below.

[0058] Preferably, each post has a rectangular section, with the longer side of the rectangle parallel to the frame rails.

[0059] According to a particular aspect and as illustrated in Figures 2 And 3At least one of the supports includes an opening 47 in its upper part, in its peripheral wall, to allow rainwater to be received from a channel connected to said opening 47, and to allow the water to flow into the post. In one embodiment, a pipe (not shown) opens into the opening 47 and is connected to an opening 947 in a waterproofing membrane 9 (See example in Figure 8 ) arranged on top of the ceiling frame to allow water to flow from opening 947 into the post 4 through opening 47.

[0060] In one embodiment, the fact that the four posts are hollow and open or hinged at their top and bottom ends allows the interior space of the post to be freed up to permit rainwater to flow from a post of a higher building module to a corresponding post of a lower building module. All or part of the post ends can be closed depending on the desired building configuration. Thus, if there is no second module superimposed on the building, the top ends of the posts can be closed.

[0061] Advantageously, a funnel-shaped connecting piece is positioned in the upper end of the post of the lower building module to receive the lower end of the corresponding post of the upper building module, and to allow rainwater to flow without leakage from one module to the other, thus preventing water from escaping at the post junction. Conversely, the funnel-shaped connecting piece can be positioned in the lower end of the post of the upper building module to fit into the upper end of the corresponding post of the lower building module.

[0062] For each upright 4, an upper connecting system 5,6, detailed below, connects the upright 4 (at its upper end) to a longitudinal member 31 of the ceiling frame 3 and to a cross member 32 of said frame. Similarly, a lower connecting system 5',6' is provided to connect the upright 4 (at its lower end) to a longitudinal member 21 of the floor frame 2 and to a cross member 22 of said frame. Chassis

[0063] The ceiling frame 3 comprises two wooden stringers 31 connected to each other by two wooden cross members 32. Preferably, each cross member is fitted with a riser 32A, which preferably extends to the post, to provide an upper face (edge) of height substantially equal to that of the upper face of each stringer, which allows the waterproofing membrane 9 to be fixed effectively to said upper faces to ensure the watertightness of the structure.

[0064] The floor frame 2 also includes two wooden stringers 21 connected to each other by two wooden crossbeams 22. As detailed below, each stringer is connected to a crossbeam by a fitting system to allow the corresponding frames to be riveted to the uprights, which are equipped with fitting systems.

[0065] The floor frame and ceiling frame may also include elements, such as ceiling or floor elements, for example intermediate cross members 23, 33, and / or insulation and "vapor retarder" or "vapor barrier" membranes, which extend between the stringers and cross members of the frame. Hardware system fixed to a chassis rail and cross member

[0066] The 5,6 connection system described below for connecting the upper part of a stud to the ceiling frame is also applicable to the 5', 6' connection system used for connecting the lower part of the stud to the floor frame. The flange cutout, shown below, may or may not be omitted for the lower connection system, and the flange connecting to the spar of one 5' part (assembly fitting system) of the connection system may have the same height as the flange connecting to the spar of the other 6' part of the connection system. One or more openings for the attachment device in the lower connection system (floor frame fittings) may be used for lifting the floor frame during the manufacturing phase.

[0067] The connecting system 5, 6 includes an assembly fitting system 5 (see for example Figure 5 And Figure 6). The assembly fitting system 5 includes a wing 531 which has a fixing part 5310 to the spar 31 and an assembly part 5314 which extends along the axis of the spar projecting from the end face of the spar 31. The term "axis of the spar" or axis of the cross member means the longitudinal axis, preferably central, of said spar or of said cross member.

[0068] According to one embodiment, the assembly part 5314 is coplanar with the fixing part 5310. The assembly part 5314 extends vertically and prolongs the fixing part 5310.

[0069] Advantageously, the fixing part 5310 extends into a slot formed vertically at one end of the spar 31 in the vertical mean plane of the spar.

[0070] In one embodiment, the mounting portion 5310 is attached to an elongated metal plate, called the top plate 5311, which extends over and along an end portion of the upper face of the spar 31, preferably within a recess formed at one end of the spar's upper face so that the plate extends through the overall thickness of the spar. Advantageously, the top plate 5311 is attached to the spar on the side of the spar's upper face. Advantageously, the upper face of the top plate, which may include a compensating plate (not shown), extends substantially flush with the upper face of the spar. The mounting portion 5310 of the wing 531 can be pre-assembled to the top plate 5311 by means of tabs 5310A cut into an upper edge of the mounting portion 5310 that engage in corresponding slots formed through the top plate.The fixing part 5310 is preferably welded to the upper sole 5311.

[0071] The fastening portion 5310 is preferably also attached to another elongated metal plate, called the bottom flange 5312, which extends against and along an end portion of the lower face of the spar, preferably within a recess formed at one end of the lower face of the spar so that the flange extends through the overall thickness of the spar. The fastening portion 5310 can be pre-assembled to the bottom flange 5312 by means of tabs 5310B cut into an upper edge of 5310 that engage in corresponding slots formed through the bottom flange. The fastening portion 5310 is preferably welded to the bottom flange 5312.

[0072] The sole or each sole extends orthogonally (horizontally) to the fixing part, to be fixed to the stringer.

[0073] The upper sole 5311 has a part 5318 which extends above the assembly part 5314. Said part 5318 of the upper sole 5311 thus extends cantilevered from the spar 31 in the fixed state of the upper sole to the spar.

[0074] The threaded connecting piece 85 extends through the cutout 58 formed in the upper part of the assembly part 5314 and has a threaded, preferably blind, orifice 856. The orifice 856 preferably opens into an orifice 5316 formed through the upper plate 5311 to allow a lifting piece 86 to be screwed into the threaded connecting piece 85 through the orifice 5316 formed in the part 5318 of the upper plate 5311.

[0075] The upper plate 5311 is fixed, preferably welded, to the wing 531. It can thus be provided that the upper plate 5311 is welded to the fixing part 5310 and preferably to the assembly part 5314. Advantageously, the threaded connecting piece 85 is welded to the part 5318 of the upper plate 5311.

[0076] The threaded hole 856 in the connecting piece 85 allows the lifting piece 86 to be fixed so that it extends upwards (specifically on the side of the base 5311 opposite the connecting piece 85). Thus, when fixed, the lifting piece 86 can extend upwards from the upper base 5311 to allow the passage of a hook that engages with the lifting piece 86. The lifting piece 86 remains removable (unscrewable), particularly during transport of the structure, and also once the structure is installed on site, to minimize its height.Positioning the threaded connecting piece 85 in a wing cutout at a height no higher than the spar allows for the efficient placement of a sealing membrane 9 to cover the ceiling frame spars. This is achieved without interference from the lifting aid system formed by the lifting piece 86, which is unscrewable and therefore removable, and the threaded connecting piece 85, which remains within the ceiling frame's dimensions. The sealing membrane 9 can be easily perforated to create an opening 985 at the level of the threaded opening 856 in each connecting piece 85, thus enabling the lifting piece 86 to be mounted and dismounted at various stages of the structure's life (transport, on-site installation).In one particular configuration, membrane 9 covers the inner faces of the ceiling frame's stringers and crossbeam extensions and is fixed, for example by gluing, to the upper faces of the stringers and crossbeam extensions, as well as to the upper flanges. Preferably, the membrane has edges that fold down on the exterior side of the structure so as to cover the outer faces of the stringers and crossbeam extensions and / or the crossbeams of the ceiling frame.

[0077] The threaded connecting piece 85 may have a cross-section whose shape is complementary to the shape of the cutout 58 formed in the assembly part 5314 of the wing 531, so that the forces applied to the lifting part, for example a lifting ring, (in particular bending or torsion) can be efficiently transmitted from the connecting piece to the wing. It can be envisaged that the force transmission will occur through the complementary shape of the cutout 58 and the connecting piece 85, without the need for welding, when the shape of the cutout prevents the connecting piece 85 from being drawn out by the open edge of the cutout 58 (for example, in a vertical direction). An example of such a shape is illustrated in Figures 6 And 7, with an inverted trapezoidal shape, i.e., where the open edge of the cutout forms the shorter base of the trapezoid. When the shape of the cutout does not prevent part 85 from being withdrawn by the open edge of the cutout 58, as illustrated for example in Figure 4 And 5 , with a rectangular shape, preferably square (i.e. where the open edge of the cutout forms one side of the square), then the connecting piece 85 is welded to part 5314 of the wing 531 and preferably to the upper sole 5311 to ensure good transmission of forces.

[0078] Similarly, the assembly fitting system 5 also includes a wing 532 having a fixing part 5320 fixed to the cross member 32 and an assembly part 5324 which extends along the axis of the cross member projecting from the end face of the cross member 32.

[0079] According to one embodiment, the assembly part 5324 is coplanar with the fixing part 5320. The assembly part 5324 extends vertically and prolongs the fixing part 5320.

[0080] The fixing part 5320 extends into a slot formed vertically at one end of the cross member 32 in the vertical mean plane of the cross member.

[0081] The fixing part 5320 can be provided with one (or more) fixing plates 5321 extending orthogonally (horizontally) to the fixing part, to be fixed on a lower (or upper) face of the cross member.

[0082] Each fixing part 5310, 5320 thus forms a fixing core of the assembly wings to a beam (longitudinal or cross member) of the chassis, preferably in the longitudinal axis of the beam and in the vertical median plane of the beam.

[0083] According to a preferred embodiment, the fixing part 5320 and the fixing part 5310 are connected to each other by a connecting part 533.

[0084] According to one particular aspect, the fixing part 5320 and the fixing part 5310 are formed from a single piece (for example from a cut and bent metal blank). Wing cutout and insertion of a threaded connecting piece

[0085] As mentioned above, the assembly part 5314 of the wing 531 of the assembly fitting system 5 has a cutout 58 in its upper part to allow insertion into the cutout of the threaded connecting piece 85, which has a threaded hole 856 adapted for screwing into said connecting piece 85, of a lifting piece 86, such as a ring. The ring 86 includes a threaded outer portion 865 adapted to cooperate with the thread 856 of the connecting piece 85.

[0086] The cutout advantageously presents a complementary shape to a section of the connecting piece 85. According to an embodiment, for example illustrated in the Figure 4 Or 5 The cutout is rectangular, preferably square, and the connecting piece 85 is a parallelepiped, for example a cube. According to one embodiment, for example illustrated in the Figure 6 Or 7 , the cut is in the shape of an inverted trapezoid and the connecting piece 85 is a piece with a cross-section in the shape of an inverted trapezoid. Hardware system fixed to the upright

[0087] The connection system also includes an assembly fitting system 6 fixed, preferably welded, to the peripheral wall of the upright 4.

[0088] The assembly fitting system 6 includes a first assembly wing 61, for riveting assembly with the assembly part 5314 of the wing 531 connecting to the spar 31 of the ceiling frame 3; and a second assembly wing 62, for riveting assembly with the assembly part 5324 of the wing 532 connecting to the cross member 32 of the ceiling frame 3.

[0089] Wing 61 extends orthogonally to a face 461 of the upright, and wing 62 extends orthogonally to a face 462 of the upright, adjacent to face 461. Each wing thus extends in a vertical plane, orthogonally to the face of the upright to which it is attached, preferably at a distance from the planes of the upright faces that are adjacent to the attachment face. Advantageously, each wing 61, 62 extends along a median longitudinal axis of the face 461, 462 to which said wing is attached.

[0090] Preferably, the fitting system 6 includes a connecting part 63 which connects the two wings 61, 62. The two wings 61, 62 extend orthogonally to each other.

[0091] In one embodiment, the assembly fitting system 6 is made from a single piece by cutting and bending a sheet metal blank. Alternatively, the wings 61, 62 can be formed from two separate pieces welded to the upright 4.

[0092] According to one particular aspect, wing 62 extends below opening 47 made in face 462 of the post to which it is fixed, said opening 47 being intended to collect water from a channel of the construction.

[0093] Each of the wings 61 and 62 extends parallel to the longitudinal axis of the upright, orthogonally to the face of the upright 4 to which it is fixed. When the structure is on a horizontal floor, each upright is then vertical and the wings 61, 62 also extend vertically from the upright towards a cross member or stringer of the ceiling frame.

[0094] As mentioned above, a fastening system, which may be identical or similar to fastening system 6, is fixed to the lower part of the upright. As a reminder, the terms "upper" and "lower" are defined with reference to the structure being positioned on a horizontal surface, with the uprights vertical. The fastening system at the lower part of the upright has one flange parallel to flange 61, and another flange parallel to flange 62 of the upper fastening system.

[0095] In the assembled state of the upright 4 to the ceiling frame via the fitting systems 5,6, the upper edge 68 of the wing 61 is located flush with or below the bottom 586 of the cut 58 of the assembly part 5314 of the corresponding wing 531 of the assembly fitting system 5.

[0096] The assembly part 5314 of the wing 531 of the assembly fitting system 5, through which the cutout 58 is made, is moved away from the inner vertical face of the spar 31 to which said assembly part 5314 of the wing 531 is fixed, which allows the connecting piece 85 to extend across the cutout 58, without encroaching inside the space delimited by the beams of the ceiling frame.

[0097] The inner vertical face of the side member 31 is the face of the side member that is opposite the other side member of the chassis. The side member has an outer vertical (or lateral) face, parallel to the inner vertical (or lateral) face, but whose normal is oriented towards the outside of the chassis, and upper and lower (horizontal) faces.

[0098] The assembly wing 61 of the fitting system 6 is assembled by riveting with the assembly part 5314 of the wing 531 (connecting to the longeron 31) of the fitting system 5. Similarly, the assembly wing 62 of the fitting system 6 is assembled by riveting with the assembly part 5324 of the wing 532 connecting to the cross member 32.

[0099] The arrangement of the cutout 58 in the wing 531, and of the upper edge 68 of the wing 61 allows the positioning of the connecting piece 85 tapped through the cutout 58 of the wing 531, and above the upper edge 68 of the wing 61.

[0100] Preferably, the upper edge of the assembly part 5314 of the wing 531 and the upper edge of the wing 61 are located at a height which remains lower than the upper end of the upright.

[0101] As an alternative or in addition, it could be provided that the cutout which receives the threaded connecting piece is made in the assembly part of the wing fixed to the cross member of the ceiling frame. Lifting function

[0102] The lifting function is thus enabled by the integration into the hardware system of a threaded connecting piece 85 which not only forms a receiving piece for the screw fixing of a lifting piece 86 (such as a lifting ring) that can be easily mounted and removed from the structure, but which also ensures good transmission and distribution of lifting forces between the posts 4 and the beams 31, 32 of the ceiling frame, by its coupling, preferably with welding, to the cut 58 made in a wing of the fitting system, which is fixed by means of another wing of the fitting system to a post, and, preferably, by its fixing (advantageously by welding) to the upper flange 5311.

[0103] This design allows the forces to be transmitted during lifting to be distributed between the wings of the two fitting systems 5, 6. The wings attached to the ceiling frame take the forces due to the self-weight of the ceiling (roof) and the wings of the upright take the forces due to the weight of the posts (uprights) and the floor. Process

[0104] An example of a manufacturing and assembly process for a modular building, as presented above, is described below.

[0105] The method is described for attaching a fitting system 6 to a stud 4 (at the top of the stud) for riveting the fitting system 6 to a fitting system 5 attached to a beam 31, which in the examples is a longitudinal member 31, and to a beam 32, which in the examples is a cross member 32 of the ceiling frame. Although less advantageous, it would be possible to use beam 31 as a cross member and beam 32 as a longitudinal member.

[0106] The method can also be applied to the fixing of an additional 6' fitting system, in the lower part of the upright, with a view to the riveting of the additional 6' fitting system (in the lower part of the upright) with another 5' fitting system fixed to a longitudinal member and a cross member of the floor frame.

[0107] The fittings used at the bottom of the upright can be identical or similar to those used at the top. It should be noted that the fittings for connecting the bottom of the upright to the floor framing may or may not have one or more cutouts or openings for the passage of a hook or a receiving element for a lifting component, such as a ring, which itself may be designed to be passed through by a hook for lifting. It is possible to ensure that the fittings used at the top and bottom are identical to minimize the number of different parts required.

[0108] In addition, the description given below for an amount located in a corner of the construction applies to the other amounts located in the other corners to connect to each of these other amounts a cross member and a stringer of the ceiling frame, and to connect to each of these other amounts a cross member and a stringer of the floor frame. Welding of wing assemblies to a post

[0109] The process thus includes the following steps for each upright. As a reminder, the terms top, or upper, and bottom, or lower, are defined by reference to the positioning of the structure on a horizontal ground, with the uprights being vertical.

[0110] The assembly fitting system 6 is welded to the upright at its upper part. The two wings 61 and 62 extend orthogonally to each other and parallel to the longitudinal axis of the upright. Wing 62 is below the opening 47 designed to collect water from a channel in the structure.

[0111] As mentioned above, a 6' assembly fitting system, which may be identical to the 6 assembly system, is fixed to the lower part of the upright. The assembly fitting system has one flange parallel to the 61 flange, and another flange parallel to the 62 flange. Ceiling frame connection fitting system

[0112] The fitting system 5 includes, as recalled above, a connecting wing 531 to the longeron 31 and a connecting wing 532 to the cross member 32. Advantageously, the fitting system 5 also includes the upper flange 5311 which is welded to the upper edge of the fixing part 5310 of the connecting wing 531, and preferably welded to the connecting piece 85 tapped and housed in the cutout 58 provided in the upper part of the assembly part 5314 of the connecting wing 531. Preferably, the upper sole 5311, by its part 5318, is welded to the assembly part 5314 of the wing 531. Advantageously, the threaded connecting piece 85 is also welded to the assembly part 5314 of the wing 531 in particular along the edges of the cutout 58.

[0113] According to one embodiment, in which the fitting system 5 also includes the lower plate 5312, said lower plate 5312 is welded to the lower edge of the fixing part 5310 of the connecting wing 531. Galvanization

[0114] The entire frame and hardware systems can then be galvanized.

[0115] The entire frame and its welded hardware (previously riveted to other hardware attached to the chassis), preferably welded, maintain a compact size that allows for easy transport and galvanization. The overall corrosion resistance is also high because the welds on the hardware are protected by the hot-dip galvanizing zinc.

[0116] The pre-welded flanges of the post fitting systems, designed to be riveted to the corresponding flanges of the floor and ceiling frame fitting systems, eliminate the need for welding at the assembly site (also known as 3D assembly) of the building module when assembling the uprights with the floor and ceiling frames. Conversely, if there were no assembly flanges attached to the uprights intended to be riveted to the corresponding assembly sections of the flanges attached to the frames, and if welding were required between a galvanized upright and the connecting fittings attached to the frames, a layer of galvanization would have to be locally removed from the upright before it could be welded to the connecting fittings attached to the frames.

[0117] During the 3D modeling process, the assembly by riveting without welding of the wooden frames, equipped with fitting systems fixed to the frame beams, with metal uprights equipped with pre-welded fitting systems, also makes it possible to pre-equip parts of the construction such as ceiling and floor frames, before the assembly corresponding to the 3D modeling, without risk of damage to said equipment which could occur (during the 3D modeling) if the assembly were carried out by welding, due to possible projections. Attaching wings to a longitudinal member and a cross member of the ceiling frame

[0118] The wing 531 of the fitting system 5 is fixed to a spar 31 of the ceiling frame by the fixing part 5310 which is inserted into a slot provided in one end of the spar 31, preferably in the vertical median plane of the spar 31.

[0119] Preferably, the fastening part 5310 is in the form of a plate which extends vertically inside the longeron and is extended by the assembly part 5314 which extends projecting from the end of the longeron and which is intended to be riveted to the wing 61 attached to the post 4. Advantageously, the entire assembly part 5314 and the fastening part 5310 of the wing 531 extend along the longitudinal axis of the longeron 31.

[0120] Similarly, the wing 532 is fixed to the cross member 32 of the ceiling frame by the fixing part 5320 which is inserted into a slot provided in one end of the cross member 32, preferably in the vertical median plane of the cross member.

[0121] Preferably, the fastening part 5320 is in the form of a plate which extends vertically inside the cross member and is extended by the assembly part 5324 which projects from the end of the cross member 32 and is intended to be riveted to the wing 61 attached to the post 4. Advantageously, the entire assembly part 5324 and the fastening part 5320 of the wing 532 extend along the longitudinal axis of the cross member 32.

[0122] Fasteners, such as pins or screws, are driven into the corresponding frame members (side member and cross member) to secure each fastener part 5310, 5320 engaged in a slot in the side member 31 or cross member 32. The fasteners extend transversely across the side member or cross member and pass through the fastener part 5310, 5320. Holes may be pre-formed in the fastener part 5310, 5320 for the passage of the fasteners or may be formed by the fasteners themselves during installation (e.g., with self-drilling screws). Alternatively, fasteners (such as screws) may be used that extend vertically through the flange 5311 and, optionally, the flange 5312.

[0123] Wings 531, 532 are made of metal, preferably steel, as are wings 61, 62 to which wings 531, 532 are riveted.

[0124] When present, the lower flange 5312, which is welded to the wing 531, is attached to the longeron on the underside of the longeron. When present, the flange(s) 5321 are welded to the attachment part 5320. Assembly of the upright wings with the wings attached to the side member and the cross member

[0125] For assembling the structure (3D modeling), the flanges 531 and 532 of the fitting system 5, which are attached to the beams 31 and 32, are positioned opposite the flanges 61 and 62 of the upright, respectively. Flange 531 is then riveted to flange 61, and flange 532 is riveted to flange 62. Several rivets are used to ensure a secure connection between the flanges. In the example shown in the figures, the connecting portion 533 is superimposed on the connecting portion 63.

[0126] The assembly part 5314 of the wing 531 is in particular positioned against the wing 61 so as to position the bottom of the cutout 58 flush or above the upper edge 68 of the wing 61, to allow the passage of the threaded connecting piece 85.

[0127] Preferably, the wings 61, 62 and 531, 532 do not protrude from the upper end of the upright 4. The threaded connecting piece 85 which is housed in the cutout 58 and which extends above the upper edge 68 of the wing 61, remains included in the footprint (volume) of the construction delimited by the uprights and the ceiling and floor frames.

[0128] Furthermore, the fact that the connecting fitting formed by the wing 531, and that the connecting fitting formed by the wing 532, extend along the longitudinal axis of the longeron 31, respectively of the cross member 32, and in particular extend in the vertical mean plane of said longeron or of said cross member, allows a good distribution of forces during lifting, and a limitation of parasitic moments.

[0129] The riveting of the wings of the lower part of the upright with the corresponding wings of a longitudinal member and a cross member of the floor frame can be carried out as described above for the wings of the upper part of the upright with the corresponding wings of a longitudinal member and a cross member of the ceiling frame.

[0130] The assembly operations between a post and each frame are carried out for each post, which allows the 3D rendering of the construction to be obtained.

[0131] The structure can be lifted by attaching sling hooks (connected to a crane) to lifting parts 86, such as rings, which are screwed into the threaded connecting parts 85 and which extend outward from the floor frame beams (and the top flanges 5311) by being screwed into the threaded connecting parts 85, preferably through said top flanges 5311.

[0132] As mentioned above, the presence of the 4 metal posts as uprights, and the arrangement of the connecting fittings between posts and frame beams in the beam axis, ensure good rigidity of the construction and good load transfer, which avoids the need to use a spreader bar. Superposition of building modules

[0133] It is possible to plan to superimpose two construction modules, particularly in the event of a need for extension following the installation of a first construction module, as presented above, by positioning a second construction module above the first module, so as to connect the uprights of the second construction module to the uprights of the first construction module to allow water to circulate from the uprights of the second construction module through the uprights of the first construction module. Juxtaposition of building modules

[0134] A second modular structure can be positioned alongside a first modular structure. When two modular structures are placed side-by-side longitudinally, a sealing strip (for example, made of EPDM) can be added to extend over the two adjacent stringers in order to cover and seal the gap between the stringers of the two adjacent modular structures. With the lifting members removed, the sealing strip also preferably covers at least part of the corresponding openings 985 provided through the sealing membrane 9, which extend opposite the corresponding threaded holes 856 of the connecting members 85.

[0135] The invention is not limited to the embodiments illustrated in the drawings. Consequently, it must be understood that, where the features mentioned in the appended claims are followed by reference numerals, these numerals are included solely for the purpose of improving the intelligibility of the claims and are in no way limiting the scope of the claims.

[0136] Furthermore, the term "including" does not exclude other elements or steps. In addition, features or steps described with reference to one of the embodiments set out above may also be used in combination with other features or steps from other embodiments set out above.
