  The present invention relates to a device for construction, in particular of the residential type. However, although more particularly intended for such applications, it may be used for any other type of

  construction especially for seismic and cyclonic zones.

  As shown in Figure 1, the building device 1 comprises a roof frame 2, including rafters 12 and purlins

  11, as well as wall frames 3, 4, 5 and 6, including posts 13.

  Said device 1 also comprises stability means 7 making it possible to return it to a self-stabilizing device in X, Y and Z when the said frameworks are assembled together, so that the construction does not

  requires no additional stabilizing element.

  According to the invention, said stability means 7 comprise at least one longitudinal wind beam 8 and a transverse wind beam 30 provided at the level of said roof frame 2 and cooperating respectively with, on the one hand, at least two flanges of transverse stability 10, 10 ', provided at the level of the framework of the transverse walls 4, 6.and, on the other hand at least two longitudinal stability blades 9, 9', provided at

  the framework of the longitudinal walls 3, 5.

  Said rafters 12 are arranged perpendicular to said wind beam 8 and common purlins 11, sand purlins 15, 21 and

  reinforced purlin 16 are arranged in the longitudinal direction.

  Said wall frames 3 and 5 include posts, preferably metal 13, the latter being in the example of Figure 1

  fixed at their upper end to said rafters 12.

  Said metal posts 13, which support part of the

  weights of said roof frame 2, are fixed to anchoring means 14.

  Said wind beam 8 comprises a continuous and rigid purlin 15, extending over a length substantially equal to that of said device 1 and a reinforced rigid and continuous purlin 16, arranged parallel to said purlin 15 and also extending from

  preferably over a length substantially equal to that of said device 1.

  Said wind beam 8 further comprises a first trellis made up of elements 17, 17 ', 17 "so as to connect said purlin

  sand pit 15 with said reinforced purlin 16.

  According to the embodiment of Figure 1, the elements of

  first trellis 17, 17 ', and 17 ", are arranged in the shape of a Saint Andrew's Cross.

  According to another advantageous embodiment of the invention, said trellis elements are arranged in any other pattern allowing the connection between said purlins 15 and 16 and in particular may be arranged in a V shape. Said wind beam 8 thus constituted by said purlins 15 and 16 as well as mesh elements 17, 17 ', and 17 ", form a structure

  horizontal rigid and continuous over the entire length.

  According to the embodiment of Figure 1, said beam at

  wind 8 is placed flat at the level of said rafters 12.

  According to the invention, said wind beam 30 comprises at least two continuous and rigid rafters 12, of lengths substantially equal to the width of said device 1. Said wind beam 30 further comprises a second trellis made up of elements 31, 31 ′ , 31 "so as to connect

  jointly said crossbowmen between them.

  According to the embodiment of FIG. 1, the elements of the

  second trellis 31, 31 ', and 31 ", are arranged in the shape of a Saint Andrew's Cross.

  According to the example in FIG. 1, in order to improve the stability of the device and in the case of a construction which can be subjected to high stresses and in particular of the seismic or cyclonic type, an additional trellis composed of elements 32 is provided. at the level of the rafters opposite to said wind beam 30, however these elements 32 may in other

  device uses be removed.

  Referring to FIG. 2, it can be seen that the device 1 can be covered with panels 18, 18 ′ and 18 "intended to cover said frameworks with walls 3, 4, 5, and 6 as well as a cover 19, partially shown in the view of Figure 2, and intended to cover said frame

roof 2.

  Referring more particularly to Figures 1 and 3, the assembly of said stability means 7 therebetween and the operation of said device 1 are as follows: the longitudinal wind beam 8 takes up the transverse forces or pushes exerted on the walls or facades 3 and 5

  and transmits them directly into the transverse stability stages 10 and 10 '.

  To this end, said transverse stability blades 10 and 10 '

  are subject to said sand failure 15 as well as said reinforced failure 16.

  The subjugation between said stability blocks 10 and 10 ′ and respectively said plate 15 and reinforced 16 purlins is achieved by

  assembly and fixing means 20 '.

  According to the exemplary embodiment of FIGS. 1 to 4, said assembly and fixing means 20 ′ consist of go ussets

cooperating with bolts.

  Naturally, the skilled person will be able to apply all his

  knowledge of assembly of metal tubes or profiles.

  For example, according to another advantageous embodiment of the invention, the assembly can be obtained by welding between said stability plates

  transverse 10, 10 ′ and said wall 15 and current 16 purlins.

  The transverse wind beam 30 takes up the longitudinal forces or thrusts exerted on the walls or facades 4 and 6 and transmits them to the sand pits 15 and 21 which transmits them on the booms

longitudinal stability 9 and 9 '.

  To this end, the long-term stability d ites i nd 9 and 9 '

  are subject respectively to the blackout failures 15 and 21.

  In the same way as for said transverse stability blades 10, 10 ', said longitudinal stability blades 9, 9'

  comprise fixing and assembly means 20.

  These assembly and fixing means 20 are constituted in the example of Figures 1 to 4 by gussets cooperating with bolts. However, again, the skilled person can apply all his knowledge in assembly and fixing to achieve

  the subjection between said blades and said wind beam 8.

  According to the example of FIG. 1, the longitudinal stability pallets 9 ′ and transverse stability 10 ′ are placed on the wall frameworks 5 and 6 opposite to those 3 and 4 o said longitudinal flanges 9 and

transverse 10.

  The various forces, whether longitudinal or transverse exerted at the level of the walls 3, 4, 5, 6 and taken up by the said beams in the wind 30 and 8, are thus transmitted to the different levels of stability 9, 9 ', 10, 10 ', so as to limit the longitudinal transverse movements eVou or the deformations of said device (1). These efforts are then

  communicated at said anchoring means 14 of the device 1 to the ground.

  For this, said longitudinal stability blades 9, 9 ', and

  transverse 10, 10 ′ are subject to said anchoring means 14.

  In the example, said anchoring means 14 are constituted

  concrete blocks on which the said stability blocks are fixed.

  These different anchoring means 14 to the ground also serve as the basis for the various posts 13 which are fixed to their base in particular by plate and

hook anchor bolts.

  Given the forces and pressures that the

  stability means 7, they are made of a metallic material.

  At the level of the wind beams 8 and 30, preference will be given to reinforced purlins 16 and sand plates 15, 21 forming frames and produced from steel profiles laminated in HEA or in tube. Said reinforcements 17, 17 ', 17 "and 31, 31', 31" will be produced from, for example, angles

laminates or tubes.

  According to the invention, said transverse stability blades 10 and 'comprise a horizontal cross member 22 secured to said wind beam 8, a vertical upright 22' as well as diagonals 23 and 23 '. said

  diagonals 23 and 23 'are arranged in the form of an inverted V.

  However, according to another advantageous embodiment of the invention, said diagonals can be arranged in the form of a cross of

Saint Andrew.

  The longitudinal stability booms 9 and 9 'are preferably formed from diagonals 24 and 24' subject on the one hand to the plate fault 21 or 15 and on the other hand to a horizontal crosspiece 25

  subject to two consecutive metal posts.

  Said blocks also comprise two diagonals 26 and 26 ′ which are fastened on the one hand to said cross member 25 and on the other hand to two concrete blocks. This particular form of "enlarged" inverted V-shaped platform increases the space available inside said platform and allows the installation of a door or window, however, in other cases, it

  can also be in the shape of a Saint Andrew's cross.

  Given the significant efforts exerted on the various stages 9, 9 ', 10 and 10', these stages are made of a metallic material and made up for the uprights in laminated or tube profile and for the diagonals in rolled angles or possibly in tube for example round

or square.

  Referring more particularly to FIG. 2, it can be seen that said frameworks of walls 3 and 4 are covered with panels 18, 18 ′ and 18 ". As said device 1 is self-stable in X, Y and Z. said panels ( 18, 18, 18 ") are preferably free from a supporting or stabilizing element of said additional device (1) so that they can be produced from

light material.

  Said panels can also, because of their very light structure, be prefabricated in the workshop and assembled on site at the level of the

construction site.

  Said panels 18, 18 ′ and 18 "are, in the example of FIG. 2, composite panels composed of different layers and in particular of insulation layers and of exterior and interior facing layers. In the embodiment of the figures 1 to 5, said panels are assembled to said wall frameworks 3, 4, 5, and 6 after

assembly of said device 1.

  That said, according to another advantageous embodiment of the invention, said wall frameworks 3, 4, 5 and 6 and said longitudinal stability booms 9, 9 'and transverse 10, 10' as well as the posts 13 are integrated into the interior of the composite panels so as to reduce the stages of construction of said dwelling and thus to reduce the duration of the site and

  also to hide the metal frame.

  Said roof frame 2 can also be covered with a

  cover 19 as shown in Figure 2.

  However, and as shown in Figures 4 and 5, the home can also include a roof, in this case, said longitudinal wind beam 8 will be located between the bottom of the rafters and the top of the suspended ceiling, and in the case of 'a one-story building, it will be between the underside of the floor framing and the top of the suspended ceiling. Naturally, other embodiments, within the reach of those skilled in the art, could have been envisaged without thereby departing from the

  scope of the invention defined by the claims below.
