Definitions
- the present invention relates to a framework of building made from cold sections forming posts and sleepers and connected together by joining pieces produced as cold pieces profiled, having a shape allowing their stacking.
- connection pieces of posts and sleepers are made in the form of bent boxes adapted to receive the ends of the profiles to assemble. Then, the case is reinforced by addition of a reinforcement piece which will be welded to the construction site.
- connecting pieces leads considerable disadvantages. We see in particular that these connecting pieces have a structure relatively complex and that they are heavy and bulky, making transportation difficult and storage, and their assembly requires tools specific. These drawbacks exclude the use of composite posts and sleepers formed for example by assembly of two C profiles arranged back to back. Through therefore, we must be content with simple profiles and to have an acceptable rigidity, the posts at relatively short distances.
- this connecting piece has the disadvantage of not presenting, at its upper part, wing flange capable of being bolted to sleeper wings.
- the connecting piece in question allows limited reinforcement of sleepers and beams and should therefore be reserved for construction of small buildings.
- this connecting piece has the downside of requiring two separate elements this which multiplies the number of different pieces to be stored and causes an increase in time and labor for fixing to posts and crosspieces.
- the object of the present invention is to provide a building framework which overcomes the disadvantages of the state of the art, which have just been described, that is to say of which the connecting pieces of the beams and sleepers have only one element capable of providing alone sufficient reinforcement for construction of large buildings.
- the building frame according to the invention is characterized in that the pieces of junction are Z-shaped parts, and in that the posts and ties are each formed by two C profiles mounted back to back and connected by the pieces junction arranged between the base parts of the profiles mounted back to back, the wings of the Z-shaped junction being fixed on the faces outside of the corresponding wings of the C-sections.
- a junction piece of a post formed by two C-profiles mounted back to back and a crosspiece formed by two C profiles mounted back to back, and of which the ends to be joined are arranged in the same plane by being juxtaposed one from the other is constituted a flat base plate with two outer edges adjacent have an angle corresponding to the angle formed by the ends of the post and the cross join, while the edges adjacent to these edges, advantageously perpendicular to these, are free of edges along the length corresponding to the width of a C-section, and, when assembled, the base plate is engaged between the C-profiles of the end of the post and between the C-profiles of the end of the crosspiece, with the flanges fixed on the outer faces of the wing tips of the two C-profiles located in the same plan, post and crossbar.
- the edge of the base plate of the junction piece of a post and a crosspiece, which connects the aforementioned edges with no edges has a ledge oriented in the opposite direction to the edge of the two adjacent edges supra.
- FIG 1 shows a framework of a building comprising over its length a number of gantries 1 produced according to the present invention.
- Each gantry includes two posts 2 formed by the back-to-back mounting of two cold C profiles 3a, 3b shown in more detail in Figure 3 and two sleepers 5 mounted end to end at an angle ⁇ and each also formed by two cold sections 3a, 3b in C arranged back to back and connecting pieces 7, 8 and 9 respectively to fix the posts 2 on a foundation structure 10, to connect a post 2 to a cross 5 and to connect the two cross one to the other.
- Post leg junction piece 7 (figure 6) is formed by a cold Z-shaped part comprising a flat part 12 whose two edges opposites are folded back to form Z wings 13 oriented in opposite directions.
- the connecting piece 7 to fix the end of the post 2 on a plate 14 forming part of the foundation structure 10, we place the connecting piece 7 so that its flat part 12 either located between the bases of the two profiles 3 in C of the post and that the wings 13 of the junction piece are applied against the outer faces of corresponding wings of the two sections 3, the part 7 being welded on the plate 14.
- the fixing of the C-profiles on the Z-junction piece is made advantageously by bolting the profiles as indicates the assembly holes.
- a junction piece 8 of a post 2 and a cross member 5 is formed by a flat plate 16 of which two adjacent edges have edges perpendiculars 17, 18 forming profile wings oriented in the same direction.
- Edges 19, 20 adjacent to wing edges 17 and 18 respectively have a length which corresponds to the width of a C-profile and have no wings.
- the free ends of these edges are connected by an edge 21 which is provided with a flange 22 extending in the opposite direction to that of wings 17 and 18.
- the coin junction is placed between the bases of the two profiles 3a, 3b in C of the post 2, on the one hand, and between the bases of the two sections 3a, 3b at C of the crosspiece 5, on the other hand, so that the wings 17 and 18 are supported on the outer surfaces of the wings external sections 3a located in the same plane, of the post and the crosspiece. Since wing 22 of the connecting piece extends in the direction opposite that of the wings 17, 18, it is interposed between the inner wings of others sections 3b of the post and the cross-member. We obtain thus a very rigid assembly of the post profiles and the sleeper.
- the fixing of the junction piece on the profiles is done by bolting.
- Figure 4 shows the through holes 28 of the bolts, made in the profiles and the connecting piece.
- the part 9 for joining two crosspieces is formed by a plate plane 30 of which two adjacent edges are provided with flanges forming wings 31 and 32 and extending perpendicularly from the plane of the plate 30, in the same direction, forming the angle ⁇ between them above.
- Edges 33 and 34 adjacent to the edges 31 and 32, each perpendicular to the edge have a slightly longer length greater than the width of a C profile. These edges are devoid of wings.
- Their free ends are connected by a straight edge which is provided with a rim 35 which extends perpendicularly from the plane of the plate 30 in the direction opposite to the edges 31 and 32.
- the piece of junction is interposed between the two pairs of profiles 3a and 3b with the wings 31 and 32 resting on the outer faces of the profile wings 3a are finding in the same plane while wing 35 extends between the lower wings of the other two sections 3b of the post and the crossbar, located also in the same plane.
- Figure 10 shows the assembly of a pole 2 and a cross 5, by means of a connecting piece 8 as described with reference to FIG. 4, but provided with reinforcing pieces 40 and 41.
- the parts shown respectively in Figures 8 and 9 have a right angle shape and are configured to be bolted to the workpiece junction at edge 21 and the junction of edges 17, 18 respectively, on the free face of the part 8.
- the joining part then also comprises a ledge on its other side. Attachment of parts reinforcement 40, 41 is done by bolting as indicates the holes in the parts of reinforcement and shown in figure 10.
- the building frame according to the invention only uses cold sections which are manufactured completely before assembly and galvanized. Thanks to their general Z shape, the pieces junction can be stacked and easily transported to the site. Since the pieces of junction are simple Z-shaped parts, they do not have a low weight, which allows to realize the construction of the framework without specific tools and bulky such as cranes.
- Another advantage of the invention lies in the fact that the bases of profiles a and b of posts and sleepers are spaced a distance corresponding to the thickness of the connecting pieces, making it possible to easily mount supports for example for the realization of a showcase, glass entry doors, interior partitions or overhead crane structure. Given the arrangement of these supports between the two profiles of a post or a crosspiece, we obtain always a symmetrical support structure.
Description
La présente invention concerne une ossature de bâtiment réalisée à partir de profilés à froid formant des poteaux et des traverses et reliés entre eux par des pièces de jonction réalisées sous forme de pièces à froid profilées, présentant une forme permettant leur empilage.The present invention relates to a framework of building made from cold sections forming posts and sleepers and connected together by joining pieces produced as cold pieces profiled, having a shape allowing their stacking.
Des ossatures de bâtiment de ce type sont déjà connues. Dans ces ossatures, les pièces de jonction des poteaux et des traverses sont réalisés sous forme de boítiers coudés adaptés pour recevoir les extrémités des profilés à assembler. Puis, le boítier est renforcé par ajout d'une pièce de renforcement qui sera soudée sur le chantier.Building frames of this type are already known. In these frameworks, the connecting pieces of posts and sleepers are made in the form of bent boxes adapted to receive the ends of the profiles to assemble. Then, the case is reinforced by addition of a reinforcement piece which will be welded to the construction site.
L'utilisation de telles pièces de jonction entraíne des inconvénients considérables. On constate notamment que ces pièces de jonction présentent une structure relativement complexe et qu'elles sont lourdes et encombrantes, ce qui rend difficile leurs transport et stockage, et leur montage nécessite un outillage spécifique. Ces inconvénients excluent l'utilisation de poteaux et traverses composites formés par exemple par assemblage de deux profilés en C disposés dos à dos. Par conséquent, il faut se contenter de profilés simples et pour, avoir une rigidité acceptable, il faut disposer les poteaux à des distances relativement faibles. The use of such connecting pieces leads considerable disadvantages. We see in particular that these connecting pieces have a structure relatively complex and that they are heavy and bulky, making transportation difficult and storage, and their assembly requires tools specific. These drawbacks exclude the use of composite posts and sleepers formed for example by assembly of two C profiles arranged back to back. Through therefore, we must be content with simple profiles and to have an acceptable rigidity, the posts at relatively short distances.
On a décrit dans US-A-4342177, une ossature de bâtiment réalisée à partir de profilés en C à froid, formant des poteaux et des traverses, reliés entre eux par des pièces de jonction et présentant une forme permettant leur empilage. Ces pièces de jonction, réalisées sous forme de pièces profilées à froid, se présentent en deux parties distinctes l'une formée d'une plaque de renfort disposée entre les parties de base des profilés montés dos à dos, l'autre formée d'une cornière de renfort permettant d'une part la consolidation de la plaque de renfort et d'autre part la connexion et le renforcement des traverses et poutres.In US-A-4342177, a frame of building made from cold C profiles, forming posts and crosspieces, interconnected by connecting pieces and having a shape allowing their stacking. These connecting pieces, produced in the form of cold-formed parts, have two distinct parts, one consisting of reinforcement plate arranged between the base parts of the profiles mounted back to back, the other formed by an angle reinforcement allowing on the one hand the consolidation of the reinforcement plate and secondly the connection and the reinforcement of sleepers and beams.
Toutefois, cette pièce de jonction comporte le désavantage de ne pas présenter, à sa partie supérieure, de rebord formant aile susceptible d'être boulonné aux ailes de traverses.However, this connecting piece has the disadvantage of not presenting, at its upper part, wing flange capable of being bolted to sleeper wings.
Pour cette raison, la pièce de jonction en question permet un renforcement limité des traverses et poutres et doit être réservée, en conséquence, à la construction d'ossature de petits bâtiments.For this reason, the connecting piece in question allows limited reinforcement of sleepers and beams and should therefore be reserved for construction of small buildings.
En outre, cette pièce de jonction présente l'inconvénient de nécessiter deux éléments distincts ce qui multiplie le nombre de pièces différentes à stocker et provoque un accroissement de temps et de main-d'oeuvre pour la fixation aux poteaux et traverses.In addition, this connecting piece has the downside of requiring two separate elements this which multiplies the number of different pieces to be stored and causes an increase in time and labor for fixing to posts and crosspieces.
D'autre part, on a décrit dans GB-A-1590435, non pas une pièce permettant la jonction d'un poteau et d'une traverse pour la réalisation d'une ossature de bâtiment mais une structure de poutre obtenue par alignement avec emboítement de deux profilés à section transversale en forme de Z à bords recourbés dont les ailes présentent des largeurs différentes.On the other hand, it has been described in GB-A-1590435, not not a part allowing the junction of a post and a cross member for the realization of a building frame but a beam structure obtained by alignment with interlocking of two cross-section profiles in Z shape with curved edges whose wings have different widths.
La présente invention a pour but de proposer une ossature de bâtiment qui pallie les inconvénients de l'état de la technique, qui viennent d'être décrits, c'est-à-dire dont les pièces de jonction des poutres et traverses ne comportent qu'un élément capable d'apporter à lui seul un renforcement suffisant pour la construction d'ossature de bâtiments de grandes dimensions.The object of the present invention is to provide a building framework which overcomes the disadvantages of the state of the art, which have just been described, that is to say of which the connecting pieces of the beams and sleepers have only one element capable of providing alone sufficient reinforcement for construction of large buildings.
Pour atteindre ce but, l'ossature de bâtiment selon l'invention est caractérisée en ce que les pièces de jonction sont des pièces profilées en Z, et en ce que les poteaux et les traverses sont formés chacun par deux profilés en C montés dos à dos et reliés par les pièces de jonction disposées entre les parties de base des profilés montés dos à dos, les ailes des pièces de jonction en forme de Z étant fixées sur les faces extérieures des ailes correspondantes des profilés en C.To achieve this goal, the building frame according to the invention is characterized in that the pieces of junction are Z-shaped parts, and in that the posts and ties are each formed by two C profiles mounted back to back and connected by the pieces junction arranged between the base parts of the profiles mounted back to back, the wings of the Z-shaped junction being fixed on the faces outside of the corresponding wings of the C-sections.
Selon une autre caractéristique avantageuse de l'invention, une pièce de jonction d'un poteau formée par deux profils en C montés dos à dos et d'une traverse formée par deux profils en C montés dos à dos, et dont les extrémités à joindre sont disposées dans un même plan en étant juxtaposées l'une de l'autre, est constituée d'une plaque de base plane dont les deux bords extérieurs adjacents présentent un angle correspondant à l'angle formé par les extrémités du poteau et de la traverse à joindre, tandis que les bords adjacents à ces bords, avantageusement perpendiculaires à ceux-ci, sont dépourvus de rebords sur la longueur correspondant à la largeur d'un profilé en C, et, à l'état d'assemblage, la plaque de base est engagée entre les profilés en C de l'extrémité du poteau et entre les profilés en C de l'extrémité de la traverse, avec les rebords fixés sur les faces extérieures des extrémités des ailes extérieures des deux profilés en C situés dans un même plan, du poteau et de la traverse. According to another advantageous characteristic of the invention, a junction piece of a post formed by two C-profiles mounted back to back and a crosspiece formed by two C profiles mounted back to back, and of which the ends to be joined are arranged in the same plane by being juxtaposed one from the other, is constituted a flat base plate with two outer edges adjacent have an angle corresponding to the angle formed by the ends of the post and the cross join, while the edges adjacent to these edges, advantageously perpendicular to these, are free of edges along the length corresponding to the width of a C-section, and, when assembled, the base plate is engaged between the C-profiles of the end of the post and between the C-profiles of the end of the crosspiece, with the flanges fixed on the outer faces of the wing tips of the two C-profiles located in the same plan, post and crossbar.
Selon une autre caractéristique avantageuse, le bord de la plaque de base de la pièce de jonction d'un poteau et d'une traverse, qui relie les bords précités dépourvus de rebords comporte un rebord orienté dans le sens opposé au rebord des deux bords adjacents précités.According to another advantageous characteristic, the edge of the base plate of the junction piece of a post and a crosspiece, which connects the aforementioned edges with no edges has a ledge oriented in the opposite direction to the edge of the two adjacent edges supra.

comprenant une partie plane 12 dont les deux bords
opposés sont repliés pour former des ailes 13 du Z
orientées dans les directions opposées. Comme on le
voit clairement sur les figures, pour fixer
l'extrémité du poteau 2 sur une plaque 14 formant
partie de la structure de fondation 10, on place la
pièce de jonction 7 de façon que sa partie plane 12
soit située entre les bases des deux profilés 3 en C
du poteau et que les ailes 13 de la pièce de jonction
soient en application contre les faces extérieures des
ailes correspondantes des deux profilés 3, la pièce 7
étant soudée sur la platine 14. La fixation des
profilés en C sur la pièce de jonction en Z se fait
avantageusement par boulonnage des profilés comme
l'indique les trous d'assemblage.Post leg junction piece 7 (figure
6) is formed by a cold Z-shaped part
comprising a
En se reportant à la figure 4, on constate
qu'une pièce de jonction 8 d'un poteau 2 et d'une
traverse 5 est formée par une plaque plane 16 dont
deux bords adjacents sont pourvus de rebords
perpendiculaires 17, 18 formant ailes de profilés
orientées dans la même direction. Les bords 19, 20
adjacents respectivement aux bords à aile 17 et 18
présentent une longueur qui correspond à la largeur
d'un profilé en C et sont dépourvus d'ailes. Les
extrémités libres de ces bords sont reliés par un bord
21 qui est pourvu d'un rebord 22 s'étendant dans le
sens opposé à celui des ailes 17 et 18. Concernant ces
ailes 17 et 18, elles forment un angle β,
correspondant à l'angle des extrémités à joindre du
poteau 2 et de la traverse 5.Referring to Figure 4, we see
a
Comme le montre clairement la figure 4, la pièce
de jonction est placée entre les bases des deux
profilés 3a, 3b en C du poteau 2, d'une part, et entre
les bases des deux profilés 3a, 3b en C de la traverse
5, d'autre part, de façon que les ailes 17 et 18
soient en appui sur les surfaces extérieures des ailes
extérieures des profilés 3a situés dans un même plan,
du poteau et de la traverse. Etant donné que l'aile 22
de la pièce de jonction s'étend dans la direction
opposée à celle des ailes 17, 18, elle se trouve
interposée entre les ailes intérieures des autres
profilés 3b du poteau et de la traverse. On obtient
ainsi un assemblage très rigide des profilés du poteau
et de la traverse. La fixation de la pièce de jonction
sur les profilés se fait par boulonnage. La figure 4
montre les trous de passage 28 des boulons, pratiqués
dans les profilés et la pièce de jonction.As clearly shown in Figure 4, the coin
junction is placed between the bases of the two
La pièce 9 de jonction de deux traverses,
conformément à la figure 5, est formée par une plaque
plane 30 dont deux bords adjacents sont pourvus de
rebords formant ailes 31 et 32 et s'étendent
perpendiculairement à partir du plan de la plaque 30,
dans la même direction, en formant entre eux l'angle α
susmentionné. Les bords 33 et 34 adjacents aux rebords
31 et 32, perpendiculaires chacun au rebord
correspondant, présentent une longueur légèrement
supérieure à la largeur d'un profilé en C. Ces bords
sont dépourvus d'ailes. Leurs extrémités libres sont
reliées par un bord rectiligne qui est pourvu d'un
rebord 35 qui s'étend perpendiculairement à partir du
plan de la plaque 30 dans la direction opposée aux
rebords 31 et 32.The
Pour assembler les deux traverses, la pièce de
jonction est interposée entre les deux paires de
profilés 3a et 3b avec les ailes 31 et 32 en appui sur
les faces extérieures des ailes de profilés 3a se
trouvant dans un même plan tandis que l'aile 35
s'étend entre les ailes inférieures des deux autres
profilés 3b du poteau et de la traverse, situés
également dans un même plan.To assemble the two crosspieces, the piece of
junction is interposed between the two pairs of
La figure 10 montre l'assemblage d'un poteau 2
et d'une traverse 5, au moyen d'une pièce de jonction
8 telle que décrite en se reportant à la figure 4,
mais pourvue de pièces de renforcement 40 et 41. Les
pièces représentées respectivement sur les figures 8
et 9 présentent une forme à angle droit et sont
configurées pour être boulonnées sur la pièce de
jonction au niveau du bord 21 et de la jonction des
rebords 17, 18 respectivement, sur la face libre de la
pièce 8. La pièce de jonction comporte alors également
un rebord sur son autre face. La fixation des pièces
de renforcement 40, 41 se fait par boulonnage comme
l'indique les trous pratiqués dans les pièces de
renforcement et indiqués sur la figure 10.Figure 10 shows the assembly of a
Il est à noter que l'ossature de bâtiment selon l'invention n'utilise que des profilés à froid qui sont fabriqués totalement avant leur montage et galvanisés. Grâce à leur forme générale en Z, les pièces de jonction peuvent être empilées et facilement transportées au chantier. Etant donné que les pièces de jonction sont des simples pièces profilées en Z, elles ne présentent qu'un faible poids, ce qui permet de réaliser la construction de l'ossature sans outillage spécifique et encombrant tel que des grues.It should be noted that the building frame according to the invention only uses cold sections which are manufactured completely before assembly and galvanized. Thanks to their general Z shape, the pieces junction can be stacked and easily transported to the site. Since the pieces of junction are simple Z-shaped parts, they do not have a low weight, which allows to realize the construction of the framework without specific tools and bulky such as cranes.
Un autre avantage de l'invention réside dans le fait que les bases des profilés a et b des poteaux et des traverses sont écartées d'une distance correspondant à l'épaisseur des pièces de jonction, ce qui rend possible de monter aisément des supports par exemple pour la réalisation d'une vitrine, de portes d'entrée vitrée, de cloisons intérieures ou d'une structure de pont roulant. Etant donné la disposition de ces supports entre les deux profils d'un poteau ou d'une traverse, on obtient toujours une structure de support symétrique.Another advantage of the invention lies in the fact that the bases of profiles a and b of posts and sleepers are spaced a distance corresponding to the thickness of the connecting pieces, making it possible to easily mount supports for example for the realization of a showcase, glass entry doors, interior partitions or overhead crane structure. Given the arrangement of these supports between the two profiles of a post or a crosspiece, we obtain always a symmetrical support structure.
