Abstract

Montant de cloison courbé de manière à présenter une forme cannelée destiné notamment à être utilisé dans une cloison. De tels montants sont utilisés par exemple pour fixer des plaques de plâtre lors du montage de cloisons. Les plaques de plâtre sont fixées à l'aide de vis de deux côtés des montants dans une structure de cloison commune. Le prix du montant dépend de l'épaisseur de la tôle métallique utilisée. Sa rigidité dépend de sa forme et de l'épaisseur de la tôle utilisée. Grâce à la présente invention, selon laquelle le dos (1) du montant est pourvu de rainures transversales de renforcement (5), soit seules soit venant s'ajouter à des rainures longitudinales de renforcement (4) connues en soi dans l'art, l'épaisseur de la tôle peut être réduite de 0,56 mm à 0,4 - 0,5 mm. Il est également possible d'augmenter la rigidité en dotant les rebord (2) de rainures transversales (7). Selon l'invention, les rainures (9, 8) au dos (1) du montant s'étendent à proximité de sa courbure (6) ou à une faible distance de celle-ci.Amount of curved partition so as to have a grooved shape intended in particular to be used in a partition. Such uprights are used for example to fix plasterboard when mounting partitions. The plasterboard is fixed with screws on two sides of the uprights in a common partition structure. The price of the amount depends on the thickness of the metal sheet used. Its rigidity depends on its shape and the thickness of the sheet used. Thanks to the present invention, according to which the back (1) of the upright is provided with transverse reinforcing grooves (5), either alone or in addition to longitudinal reinforcing grooves (4) known per se in the art, the sheet thickness can be reduced from 0.56 mm to 0.4 - 0.5 mm. It is also possible to increase the rigidity by providing the flange (2) with transverse grooves (7). According to the invention, the grooves (9, 8) on the back (1) of the upright extend close to its curvature (6) or at a short distance from it.

Description

STANDARD FOR PARTITION
The present invention concerns a standard for a partition, which has recently been adopted in replacement of timber uprights in partition or equivalent structures.
The partition standard has been bent to be a post with fluted cross section. The advantage of a post made of metal over a timber upright is that it does not experience such "working" under effect e.g. of heat and moisture as is the case with wood. Nowadays in partitions plaster boards are much used, in which case the thermal expansion coefficients of the partition standard and of the board that is attached thereto are virtually the same.
Nowadays, a standard design as shown in Fig. 1 is used. By the longitudinal bends depicted here, the standard is endowed with good enough rigidity. A plaster board, for instance, is affixed with screws suited to the purpose to the side walls, or flanges 2, of the standard, on both sides of the standard. It is advisable to roughen the surface of the flange so that the point of the screw will not slip as the screw is being fixed. The material thickness of the standard is at least 0.56 mm, whereby the rigidity of the standard's flanges is good enough.
Various frame structures reinforced with the aid of bends are known in the art. Such are disclosed e.g. in the DE publicizing print No. 1 271 350 and in the GB application print No. 2,136,469. However, the structures presented in these are hollow beam structures, not partition standards of fluted shape. Since they are enclosed tubular structures, their bending properties are entirely different from those of structures with fluted shape.
In the U.S. Patent No. 4,016,700 has been disclosed, as a thermally insulating wall structure, a fluted structure. Since the purpose of the structure is to prevent heat conduction through the standard from one side to the other of the wall, the standard is so perforated that the path conducting heat is narrow and long. The structure hardly at all counteracts the curving of the standard's back, because the transversal apertures provided with marginal bends are short. In fact, the design of the U.S. reference does not aim at raw material saving as the present invention does.
Since the price of the standard is dependent on the material thickness, the object of the invention is to provide a rigid enough partition standard in which the material thickness is less than that used at present.
The metallic partition standard αr equivalent bent to fluted shape of the invention is characterized by the circumstances stated in the characteristic features part of claim 1.
The invention is more closely described with the aid of the drawings attached.
Fig. 1 presents a partition standard which is presently used.
Fig. 2 presents a standard according tα the invention.
Fig. 3 presents another standard according to the invention.
Fig. 4 displays on larger scale the detail indicated with the circle A in Figs 2 and 3.
Fig. 5 shows the section carried through the reinforcing groove 5 presented in Fig. 4, at C-C.
Fig. 6 shows on enlarged scale the detail indicated with the circle B in Figs 2 and 3, viewed from above.
Fig. 7 presents a new partition standard according to the invention, having transversal reinforcing grooves. Fig. 8 shows the sectional drawing of the preceding reinforcing groove at the back 1 of the standard, Fig. 7 D-D.
Fig. 9 shows the end of the reinforcing groove, schematically in the region of the bending point betwwn the back 1 and the flange 2 of the standard, Fig. 7 A.
Fig. 1 presents a partition standard of prior art, featuring a back 1 of the standard, flanges 2, marginal bends 3 and longitudinal reinforcing grooves 4. A standard of this kind is made of material having a material thickness not less than 0.56 mm.
The partition standard of the invention, depicted in Fig. 2, may be made of 0.4 to 0.5 mm material thickness. The cost saving compared with existing standards amounts to FIM 0.15 to 0.32 per metre if 0.5 mm material thickness is used. Requisite reinforcing is accomplished with transversal grooves 5 in the back 1, as taught by the invention. In Figs 4 and 5 is shown the end portion A, in Figs 2 and 3, of the groove 5. This reveals that the groove extends quite close to the bend 6 of the standard, and that the width of the groove end is preferably substantially the same as the width of the groove. The end of the groove 5 reinforces the standard in longitudinal direction, while the rest of the transversal groove 5 reinforces the back 1 of the standard in transversal direction.
For reinforcement of the transversal direction of the flanges 2, there have furthermore been made transversal grooves 7 in the flanges of the standard. The point B of Figs 2 and 3 is seen on a larger scale in Fig. 6, where this region has been depicted as viewed from above. The grooves 7 extend up to the bend 6.
The transversal bends of the standard in the back portion reinforce the standard to such extent that a smaller material thickness can be used. The transversal grooves 5 are made with wider spacing, and deeper, in a standard having a wide back. In a narrow standard the grooves 5 may be made with closer spacing and shallower.
The grooves 5 and 7 reinforce the standard in such manner that the back 1 and the flanges 2 are rigid enough even if the material thickness of the standard should be only 0.4 to 0.5 mm.
If one considers that in Finland alone at present already between 10 and 15 million metres of partition standard material are annually consumed, it becomes clear how economical it is to achieve even a minor reduction of the material thickness in the sheet. The importance of the invention will further increase as the use increases.
The partition standard can be made so that it has, in the back of the standard, longitudinal reinforcing grooves 4 and, in addition, transversal grooves 5 and 7. It may also be made so that it has only transversal reinforcing grooves, because the flanges 2 and grooves 3 already endow rigidity in the longitudinal direction and the ends of the transversal grooves 5 further assist. Thus the most important thing is that the standard has transversal grooves 5 in the back 1 which act both longitudinally and transversally.
In a structure according to the invention, the transversal groove ends close to the bend 6 between the back 1 and the flange 2, as has been shown in Figs 2 and 3. It has been found in experiments that the rigidity is improved if the reinforcing groove 8 continues a little over the bend 6.
The cross section of the reinforcing groove 8 has at the back 1 the cross section shown in Fig. 8. The groove 8 continues some distance over the bend and tapers down gradually, being transformed into a planar surface, like Fig. 9 shows schematically , referring to the point A of the standard.
It has thus been found that with reinforcing grooves like those in Fig. 7 even more rigid partition standards are obtained than the standards of Figs 2 and 3 reinforced with transversal grooves.
In the foregoing, embodiment examples have been presented, which may be modified within the scope of the claims. The standard has been called a partition standard because partitions in buildings are its principal application. The standard may be employed to other purposes as well in which a similar way of building can be contemplated. The standards are also intended for fixing not only plaster boards but they are also meant to serve other equivalent purposes.
