Description
- The present invention relates to a deformable profiled member.
- The invention is used in the construction industry, particularly in the sector of buildings that use prefabricated panels.
- Nowadays, for constructing dividing structures within a building such as, for example, walls and/or false ceilings, widespread use is made of prefabricated panels, for example made of plasterboard.
- In order to provide a dividing structure using prefabricated panels, generally the load-bearing frame of the dividing structure is prepared using supports and/or metallic and/or wooden profiled members, which are in turn secured to one or more elements of the building, such as walls and/or floors and/or ceilings.
- Once the frame of the dividing structure is assembled, the prefabricated panels are fixed to the supports and/or to the profiled members that make it up.
- Such structures are easy and rapid to set up and they make it possible to obtain ceilings and walls with shapes that are difficult to achieve with ordinary bricks and cement, such as for example curved shapes of walls or ceilings.
- In order to obtain dividers with curved shapes, metallic profiled members are used which can be deformed according to requirements.
- For example, there is the deformable profiled member described in
EP2673426B1 , by this same applicant. - This profiled member is C-shaped in cross-section and has a plurality of areas prepared to facilitate bending, which are substantially constituted by openings and/or cuts, on the core of the C and on its wings.
- Such openings and/or cuts weaken the structure of the profiled member and it is therefore possible to deform it in order to provide the curve.
- During erection of the frame of the dividing structure, the profiled member is in fact bent by acting on one or more of these areas prepared to facilitate bending.
- Such known art has a number of aspects that show room for improvement.
- First of all, the profiled member has:
- a plurality of mutually parallel groups of slots, extended longitudinally, on the wings of the C-shape, with each slot parallel to a slot of the other wing, and with each group composed of three slots: two end slots and one intermediate slot,
- a pair of slots, extended longitudinally, on the core of the C-shape, corresponding to the end slots of the two corresponding groups of slots arranged on the wings.
- Such a plurality and arrangement of slots, although it allows easy bending, can determine, in some types of installations, a mechanical rigidity and an unsuitable moment of inertia of the profiled member.
- The aim of the present invention is to provide a deformable profiled member that is capable of improving the known art in one or more of the abovementioned aspects.
- Within this aim, an object of the invention is to provide a deformable profiled member that can be easily and readily folded.
- Another object of the invention is to provide a deformable profiled member that has a better mechanical rigidity than similar conventional profiled members, while maintaining the same flexibility.
- A further object of the invention is to provide a deformable profiled member that has a better moment of inertia than similar conventional profiled members, with the same flexibility.
- A further object of the present invention is to overcome the drawbacks of the background art in a manner that is alternative to any existing solutions.
- Another object of the invention is to provide a deformable profiled member that is highly reliable, easy to implement and low-cost.
- This aim and these and other objects which will become more apparent hereinafter are achieved by a deformable profiled member, C-shaped in cross-section, with a core and two opposing wings, respectively a first wing and a second wing, characterized in that it has on each one of said wings and on said core a plurality of groups of slots/holes, each one of said groups having at least four slots, extending longitudinally, said slots being arranged in groups numbering at least two along lines that are mutually parallel when considering the flat extension of said profiled member.
- Further characteristics and advantages of the invention will become more apparent from the detailed description that follows of a preferred, but not exclusive, embodiment of the deformable profiled member according to the invention, which is illustrated by way of non-limiting example in the accompanying drawings wherein:
-
Figure 1 is a view of the flat extension of a portion of a deformable profiled member according to the invention; -
Figure 2 is a side view of a portion of a deformable profiled member according to the invention in an application thereof. - With reference to the figures, a deformable profiled member according to the invention is generally designated by the
reference numeral 10. - The profiled
member 10 is made of metallic material. - Such profiled
member 10 is C-shaped in cross-section, with acore 11 and two opposing wings, respectively afirst wing 12a and asecond wing 12b. - One of the particularities of the invention consists in the fact that the
profiled member 10 has, on each one of thewings core 11, a plurality ofgroups - In particular, the profiled
member 10 has: - a plurality of
first groups 14 along thesecond wing 12b, - a plurality of
second groups 15 along thecore 11, - a plurality of
third groups 16 along thefirst wing 12a. - Along the direction of extension S of the profiled
member 10, afirst group 14 and athird group 16 are arranged at eachsecond group 15. - Considering the flat extension of the profiled
member 10, as illustrated partially inFigure 1 , each one ofsuch groups slots 17, extending longitudinally, andsuch slots 17 are arranged in groups numbering at least two along lines X, Y, Z that are mutually parallel and orthogonal to the direction of extension S of the profiled member 10: a first end line X, a second end line Z and an intermediate line Y. - Specifically, the
first group 14 has sixslots 17 in aligned pairs, respectively: - two
slots 17 along the first end line X, - two
slots 17 along the second end line Z, - two
slots 17 along the intermediate line Y. - The
second group 15 has: - three
slots 17 aligned along the first end line X, of which one is a firstcentral slot 17a, - three
slots 17 aligned along the second end line Z, of which one is a secondcentral slot 17b, - a
first hole 18 along the intermediate line Y, aligned with the firstcentral slot 17a and with the secondcentral slot 17b along the direction of extension S of the profiledmember 10. - The
third group 16 has: - two
slots 17 aligned along the first end line X, - two
slots 17 aligned along the second end line Z, - a
second hole 19 along the intermediate line Y - In the example shown in
Figure 1 , thesecond hole 19 is aligned with twoslots 17 of thethird group 16 along an axis parallel to the direction of extension S of the profiledmember 10. However in variations of embodiment, not shown in the figures, thesecond hole 19 may not be aligned withother slots 17 along an axis parallel to the direction of extension S of the profiledmember 10. - Such an arrangement and configuration of slots and holes makes it possible to provide a deformable profiled member that has a higher moment of inertia and a better mechanical rigidity than similar conventional profiled members.
- Such profiled
member 10 has, along the direction of extension S, a plurality ofthird holes 20, each one interposed between two successivesecond groups 15. - Such
third holes 20 are adapted for the insertion of screws for fixing the prefabricated panels during the assembly of the dividing structure. - The profiled
member 10 has a plurality of pairs ofopenings openings second group 15. - In particular, considering the flat extension shown in
Figure 1 , theopenings core 11 and arespective wing - a
first portion 22, with a substantially rectangular profile, straddling thewing core 11, - a
second portion 23, with a substantially triangular profile, extending from thefirst portion 22, within thecore 11, with the apex directed toward thefirst hole 18. -
Such openings member 10, and also the bending of the profiledmember 10 during the application step in order to produce the required curvature. - In practice it has been found that the invention fully achieves the intended aim and objects by providing a deformable profiled member that can be easily and readily folded.
- With the invention a deformable profiled member has been devised that has a better mechanical rigidity than similar conventional profiled members, while maintaining the same flexibility.
- Finally, with the invention a deformable profiled member has been provided that has a better moment of inertia than similar conventional profiled members, with the same flexibility.
- The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims. Moreover, all the details may be substituted by other, technically equivalent elements.
- In practice the materials employed, provided they are compatible with the specific use, and the contingent dimensions and shapes, may be any according to requirements and to the state of the art.
