"Poutrelles en fer constituées par des plaques"
On connaît le procédé qui consiste à former des plaques résistant à la flexion, par exemple, dans la construction au- dessus du sol et dans la construction des ponts, en disposant plusieurs profilés les uns à côté des autres. En l'occurence, la force portante ou résistance de la plaque foxmée de cette manière, est égale à la somme de la force portante ou résis- tance des divers profilés dont la plaque est composée*
On peut.toutefois, conformément à l'invention,augmenter notablement la force portante et la résistance à la flexion en se servant du même matériel, en 'disposant les divers pro- filés les uns à côté des autres de manière que les axes pas- sant par les centres de gravité des divers profilés,
ne coin- cident pas avec l'axe de la plaque et que les profilés voisins
<Desc/Clms Page number 2>
soient chaque fois assemblés les uns avec les autres, dans le voisinage des points d'appui.
Les dessins montrent quelques exemples de réalisation de l'invention, à savoir: les figures 1 à 3 une plaque sur deux supports. :La figure 1 est une vue de face, la figure 2 une vue en plan de dessus et la figure 3 une coupe.
Les poutrelles a et b sont disposées de manière que les axes passant par le centre de gravité a',a' et b', b' ne coin- cident pas avec l'axe de la plaque e,e. Les poutrelles voisi- en d nes sont assemblées l'une avec l'autre par soudage/dans le voisinage du support c. en
La figure 4 montre xxx vue en plan une plaque maintenue par exemple, d'uneôté, et libre de l'autre. Les profilés f et g sont assemblés l'un avec l'autre dans le @oisingge du support h ou dans le voisinage de l'extrémité k, en i. A l'extrémité fixée 1,il n'est pas nécessaire de prévoir un as- semblage spécial à l'abri du cisaillement, car cet assembla- ge est assuré par les forces de fixation elles-mêmes.
L'assemblage résistant au cisaillement peut ê-tre réa- lisé par soudage ou par tout autre mode d'assemblage appro- prié. Cet assemblage peut se faire dans l'atelier ou sur les lieux de montage mêmes,pendant le montage ou après. 'assem- blage peut se faire dans le voisingge du support, dans le voisinage des extrémités du profilé, en plusieurs points de la longueur de celui-ci, ou encore partout où le calcul fait apparaître les plus grandes forces de poussée. a nature et la forme des profilés n'ont pas d'importance.
Pour assurer en même temps l'étanchéité de la plaque, on peut assembler les plaques voisines et qui se touchent par languettes et rainures ou par des dispositifs en forme de crochets qui s'Engagent les uns dans les autres.

"Iron beams formed by plates"
The process is known which consists in forming bending resistant plates, for example, in above-ground construction and in bridge construction, by arranging several profiles next to each other. In this case, the load-bearing force or resistance of the plate formed in this way, is equal to the sum of the load-bearing force or resistance of the various profiles of which the plate is composed *
However, in accordance with the invention, the load-bearing force and the flexural strength can be significantly increased by using the same material, by arranging the various profiles one beside the other so that the axes pass. owing to the centers of gravity of the various profiles,
do not collide with the axis of the plate and that neighboring profiles
<Desc / Clms Page number 2>
are each time assembled with each other, in the vicinity of the support points.
The drawings show some embodiments of the invention, namely: FIGS. 1 to 3 a plate on two supports. : Figure 1 is a front view, Figure 2 a top plan view and Figure 3 a section.
The beams a and b are arranged so that the axes passing through the center of gravity a ', a' and b ', b' do not coincide with the axis of the plate e, e. Neighboring beams are joined together by welding / in the vicinity of the support c. in
Figure 4 shows xxx plan view of a plate maintained for example, on one side, and free on the other. The profiles f and g are assembled with each other in the @oisingge of the support h or in the vicinity of the end k, in i. At the fixed end 1, it is not necessary to provide a special shear-proof connection, since this connection is provided by the fixing forces themselves.
The shear resistant connection can be made by welding or by any other suitable method of joining. This assembly can be done in the workshop or at the assembly site itself, during assembly or after. The assembly can be done in the vicinity of the support, in the vicinity of the ends of the profile, at several points along the length of the latter, or else wherever the calculation shows the greatest thrust forces. The nature and shape of the profiles are irrelevant.
To ensure at the same time the sealing of the plate, it is possible to assemble the neighboring plates and which touch each other by tongues and grooves or by devices in the form of hooks which engage with each other.
