Description

Construction structure with steel profiles with quick-connect "U" section for the formation of floor divisions.

Field of the Invention

The present invention advocates a structure constructive self-supporting (nor transmits building efforts continent, nor contributes to its stability) of steel which is intended to enable the constitution of screens for the division of workspaces (offices, premises commercial, etc.) in a simple, fast and practicable way in any time to allow subsequent redistributions.

Prior art

The partition walls have an essential function of division and / or closing of the workspaces that are enroll in the organizational systems that claim an occupation rational of these spaces for worker satisfaction as a way to improve productivity and the best use of immobilized material resources. Further, these screens exert an important decorative function by the great diversity of possible finishes that allow to adapt to Any environmental environment.

A multiple objective in the manufacture of this product is the best possible combination of a series of qualities, among others: constitutive simplicity, quick assembly and disassembly and simple, robustness, application versatility for various configurations and for different types of panel (blind, glazed, mixed).

Various solutions are known in this field. based on extruded profiles in the form of "H" (or double "T") or similar to it, being a good example the constituted by European Patent EP 0 870 880 A2. Apart from others issues, in these cases the material used is aluminum, which It offers very little resistance in case of fire.

Structuring modes of frames based on "U" or "C" shaped steel profiles. Among them, there are those who use specific profile forms to each function that are either complex or require auxiliary means , as fasteners or as screws (p. e. WO2000US 11991, in the latter case) that complicate the assembly / disassembly and They slow down. Others have reciprocal shapes attachable by sliding of the end of one profile along another which is perpendicular to it (for example WO2000AU00500); this conditions a certain assembly / disassembly order by requiring that it be free one end of the profile that plays the role of rail glide; on the other hand, once the position is reached desired, it must be fixed by some external means. There's also solutions (for example GB 19940003248) in which a profile vertical is introduced in an inclined position between two others horizontal profiles and then turn it vertically fit it between these; to determine the final mounting position the horizontal profiles have transverse stops that are reached exceeding the vertical profile, by elastic jump, some highlights lateral of the horizontal profiles; this solution does not offer sufficient reliability against horizontal efforts that could undo said elastic jump, unless further Tighten with mounting position screws.

Explanation of the invention and advantages

Faced with this state of affairs, the present invention refers to a constructive structure with profiles of steel with quick-connect "U" section for the formation of floor divisions, where each screen consists of a support frame  formed by horizontal lower base and coronation upper, by two vertical pedestals that laterally close the frame, optionally, a horizontal crossbar and by extensions, lower and upper, which are coupled, respectively, between the ends of the pedestals and those mentioned plinth and coronation, where the plinth, coronation, pedestals and crossbars are "U" cross section profiles of straight walls that has its folded longitudinal edges forming opposite tabs that at their free edge are at the pair profiled with starters regularly spaced in shape General of sawtooth that have two fronts transverse and oblique, while the lower extensions and upper have telescopic sliding adjustment with respect to the interior of said pedestals; the pedestals and the crossbars at least they have trapecial windows in which their bases are transverse and are spaced apart from one another sufficiently larger than the width of the pedestals themselves and crossbars; the bottom or floor of the crossbars is prolonged in both ends forming two tabs that at birth they have collateral necklines that have width adjusted by excess to the wall thickness of pedestals and crossbars and that are aligned in transverse direction to them, whose necklines are distanced in a measure that is set by default to the length of the major base of the trapezoidal windows and operating in conjunction with rotational elastic jump means that are established between one of the ends of said major base and the opposite edge of the trapezoidal windows in a place adjacent to the other end of this major base, as well as this distance between necklines is set by default with the one that exists between ends furthest from two opposite transverse edges of the jagged tabs and operates in conjunction with a means of elastic spring jump that are set between the corner formed by the transverse and oblique fronts of an entree jagged and a place adjacent to the corner of the jagged entree faced with it; by its end directed towards the respective lower and upper end of the pedestals, the bottoms of the lower and upper extensions extend to form one of said tabs provided with collateral necklines; And in the straight side walls of the pedestals and crossbars, there are pairs of longitudinal slots that are spaced so regular.

According to the invention, said means of Rotational elastic jump of the trapezoidal windows consist of that the major base of it links with the oblique sides of the same by means of two longitudinal songs, first and second, which extend into the trapezoidal window, the first, by means of a divergent oblique projection with its own side of the trapezoidal window, and the second, by a slight oblique highlight that, with its own side of the trapezoidal window, it links by means of a longitudinal section and that is the one that has rotational elastic jump adjustment with respect to the opposite end of said major base in conjunction with the distance between the necklines of a tongue. On the other hand, said elastic jump means rotary in the toothed recesses of the eyelashes are that the transverse and oblique fronts of these serrated entrances are linked by a longitudinal edge born from the front transverse and a projecting edge projected towards the hollow of the own profile, the distance between one of the edges being longitudinal and the corresponding protruding edge of the tab opposite, the one with rotational elastic jump adjustment with respect to  the distance between the bottoms of the necklines of a tongue.

From this recommended constitution it follows a special feature consisting in the way in which produce the two different assembly maneuvers between crossbar and pedestal (depending on whether the crossbar is coupled by the open front from the pedestal or the opposite front), on the one hand, and, on the other side, the assembly maneuver between the lower extensions and upper and, respectively, the socket and coronation, maneuver this one that is like bliss to couple the crossbar in the front Pedestal open.

The maneuver to couple the crossbar through the unopened front of the pedestal is produced by frontal insertion of the tongue (in a rotated position with respect to its longitudinal axis) through a trapecial window of the latter and then undoing the insertion turn so that, with one of the necklines of the tongue pivoting on the minor longitudinal edge, the elastic jump is achieved by which the other neckline exceeds the oblique shoulder that precedes the major longitudinal edge of the trapezoidal window. A maneuver similar to this is the one that allows the assembly of the crossbar by the open front of the pedestal, as well as to couple the lower and upper extensions with, respectively, the base and the coronation; with the obvious difference that, in this case, the tongue is located, respectively, between the tabs of the pedestal, the socket or the coronation; then, the engagement of the necklines is produced by coupling a neck of the tongue at one of the longitudinal edges and, pivoting on it, to produce the elastic jump of the opposite neckline with respect to the corresponding edge
outgoing.

This proposed constitution employs profiles of steel that offer great mechanical resistance and that can be considered flame retardant in accordance with the regulations governing the respect; the profiles are of simple configuration and, except for the tabs, pedestals and crossbars are equal to each other, and their mechanized (toothed tabs and trapecial windows) are of simple and economical manufacturing by die cutting; as later we will see, the lower and upper extensions are basically equal to each other, and, except for a possible height difference, also the socket and the coronation are basically the same; the assembly and disassembly maneuvers are fast, simple, do not require of special tool and the result is very firm and reliability

For the correct leveling of the structure a constitute, the invention contemplates a device consisting of that the bottom of the lower extension is extended by a square fold that has a neckline where a throat is rotatably coupled which is formed in a nut in which you screw a vertical screw that has its head axially immobilized to the pedestal; at the same time throughout of the bottom and top extensions funds there is a uniform succession of holes that are attached with an opening longitudinal practiced at the bottom of the pedestals. So once that the lower extension has been coupled with the socket, when doing turn the nut in one direction or another on the screw axially motionless, the ascent or descent of the pedestal is achieved in that place; this simple device makes it possible to perform the maneuver height adjustment without risk that the structure can fall.

Another feature of the invention consists in that there are hooks as a sheet metal clip that are shaped general squad, with a flat wing that is equipped with means for its mooring on the back of a side panel of the screen, and with its another wing equipped with three oblique elastic arms that in front behind are removed by die cutting of the material of this wing and that they are, a central arm and two lateral arms; arm central protrudes from one of the faces of the wing itself and the lateral arms protrude on the other side of it diverging from the central arm; the central arm forms at its end a concave fold that has its hollow facing the outer face of the wing and that are opposed to two concave folds that have lateral arms with equal concave arm fold central; The width and thickness of the sheet hitch are conveniently smaller than the length and width, respectively, of the longitudinal side walls of the pedestals and crossbars; and between the concave fold and the concave folds of the central and lateral arms there is a transverse measurement step conveniently greater than the width of said longitudinal grooves of the pedestals and crossbars. At this point it is from highlight the ingenious and simple constitution of the sheet metal clip, in that all the arms involved in the clip action are punched out from front (wing edge) behind the part central of one of its own wings; while in others known solutions these arms are born from the corner of the wing, they are torn to the edge of it by punching and, with a additional operation of certain complexity, are folded back and in opposite directions, that is, the central arm towards one of the wing faces and the side arms towards the other side. This clip system is very simple and very versatile to be used with the different types of panels that dress the structure of the screen; It has a fast and simple way of use in which just attach the clip to the back of the side panel and insert the elastic arm wing by a corresponding groove Longitudinal sides of the pedestals and crossbars.

To facilitate correct positioning and assist in the maneuver of placing the side panels of the screen, there are squares with a flat wing equipped with means for its mooring on the back of a side panel of the screen, and with its other  wing capable of entering with a convenient clearance through said longitudinal grooves of the side walls of the pedestals and crossbars.

Another feature of the invention consists in that along the bottom of the socket and the coronation there is a alternating succession of wide holes and perforations Longitudinal With it and with the existence of the windows pedestals and crossbars, there is a large Ease to make the passage of cables and pipes both in vertical as in horizontal; which facilitates the work of installation and maintenance of electricians, plumbers and the rest.

Exhibition of a preferred embodiment

Regarding the drawings and references above listed, an execution mode is illustrated in the attached drawings preferred object of the invention, which refers to a construction structure with steel profiles with section in "U" of fast union for the formation of divisions in plant. As Figure 1 illustrates, according to this structure of the invention each screen consists of a support frame formed by horizontal lower base (1) and upper coronation (2), by two vertical pedestals (3) that laterally close the frame, by, optionally, a horizontal crossbar (4) and by extensions, lower (5) and upper (6), which are coupled, respectively, between the ends of the pedestals (3) and the mentioned socket (1) and coronation (2), where the sockets (1), coronation (2), pedestals (3) and crossbars (4) are cross-section profiles in "U" of straight walls that has its longitudinal edges folded forming tabs (7) facing each other that on its edge free are on par with profiled entrees regularly generally spaced sawtooth teeth two transverse (8) and oblique (8a) fronts, while the lower (5) and upper (6) extensions have sliding adjustment telescopic with respect to the interior of said pedestals (3); the pedestals (3) and the crossbars (4), at least, have windows trapecials (9) in which their bases are transversal and are distanced from each other to a degree sufficiently larger than the width of the pedestals themselves (3) and crossbars (4); the bottom or crossbar floor (4) is prolonged at both ends forming two tabs (15) that at birth have some collateral necklines (16) having width adjusted in excess of wall thickness of pedestals (3) and crossbars (4) and that are aligned in transverse direction to them, whose necklines (16) are distanced in a measure that is set by default to the length of the major base (9a) of the trapezoidal windows (9) and that It operates in conjunction with rotating elastic jump means that are established between one of the ends of said major base (9a) and the opposite edge of the trapezoidal windows (9) in one place  adjacent to the other end of this major base (9a), as well as this distance between the necklines (16) is set by default with the that exists between the farthest ends of two edges cross sections (8) facing the toothed tabs (7) and operates in conjunction with rotating elastic jump means that are established between the corner formed by the transverse fronts (8) and oblique (8a) of a serrated recess and a place adjacent to the corner of the toothed entrant facing it; by its end directed towards the respective lower or upper end of the pedestals (3), bottom extensions bottoms (5) and upper (6) extend to form one of said tabs (15) provided with collateral necklines (16); and on the side walls Straight pedestals (3) and crossbars (4), there are pairs of longitudinal grooves (17) that are spaced on a regular basis. As Figures 1B and 1C illustrate, according to an embodiment of the invention, said elastic jump means Rotating trapezoidal windows (9) consist of the base greater (9a) of this link with the oblique sides thereof by means of two longitudinal songs, first song (10) and second edge (11), which inside the trapezoidal window (9) is prolong, the first (10), by means of an oblique projection (12) divergent with its own side of the trapezoidal window (9), and the second (11), by a slight oblique highlight (13) that, with its own side of the trapezoidal window (9), links by means of a longitudinal section (14) and which is the one with jump adjustment rotary elastic with respect to the opposite end of said major base (9a) in conjunction with the distance between the necklines (16) of a tongue (15). Also, said rotating elastic jump means in the toothed recesses of the eyelashes (7) are that the fronts transverse (8) and oblique (8a) of these serrated recesses are linked by a longitudinal edge (8b) born from the front transverse (8) and a projecting edge (8c) projected towards the hollow of the profile itself, the distance between one of the edges being longitudinal (8b) and the corresponding protruding edge (8c) of the opposite tab (7), the one with elastic jump adjustment rotary with respect to the distance between the bottoms of the necklines (16) of a tongue (15).

With these premises, the assembly between crossbars (4) and pedestals (3) occurs frontally (perpendicular) and  rotating, without tools, through the operational sequences illustrated by figures 1, 1B and 1C. First [if the coupling occurs on the unopened front of the pedestal (3)], the tab (15) is positioned as indicated in line Figure 1B is discontinued, for which, previously, it has to go through the trapezoidal window (9) in a position such as that which is indicated in dashed line; second, it is pressed in the direction indicated by the arrows to produce the necessary elastic jump to overcome the oblique shoulder (13) and reach the final position of  assembly shown in Figure 1C; the disassembly maneuver is just the opposite. When the coupling has to be done by the open front of the pedestal, a similar maneuver takes place between the tabs (7), as indicated by the two positions sequential in figure 1A.

This last maneuver is the same one used to the lower extension assembly (5) [and consequently, of the  upper extension (6)] and, as illustrated in Figures 2 through 9, performs with a front and rotating maneuver, with the pointed difference that the tongue hitch (15) of the Extensions (5 and 6) occur between the tabs (7), causing one of the necklines (16) of the tongue (15) pivots on one of the edges (8b) and, by rotating elastic jump, exceed the edge outgoing (8c).

Figures 10 to 18 illustrate the constitution and functionality of the height adjustment device of the pedestals for the necessary leveling of the structure of the bulkhead. To this end, the bottom of the lower extension (5) is prolongs (figures 10 to 15) by means of a fold (18) in square that on its front edge it has a neckline (19) where it is attached rotationally a throat (21) that is formed (figure 18) in a nut (20) into which a screw (figures 16 and 17) screws vertical (22) that has its head immobilized axially at pedestal (3). By rotating the nut (20), such as the screw (22) is axially immobilized, the pedestal (3) will slide up or down [according to the direction of rotation of the nut (20)] by telescopic slide relative to the lower extension itself (5).

Figures 19 to 27A illustrate the constitution and functionality of the means intended to enable the placement of side panels (24) on the structure of the screen. To such For purposes, there are hooks (23) as a sheet metal clip (figures 22 to 24) which are generally square, with a flat wing that is equipped with means for its mooring on the back of a side panel (24) of the screen, and with its other wing equipped with three elastic arms obliques that are pulled from front to back own material of this wing and that are, a central arm (25) and two lateral arms (26); the central arm (25) protrudes through one of the faces of the wing itself and the side arms (26) protrude on the other side of it diverging from the central arm (25); he central arm (25) forms at its end a concave fold (27) that it has its hollow facing the outer face of the wing and that is opposite to two concave folds (28) that have the arms lateral (26) to the concave fold (27) of the central arm (25); the width and thickness of the sheet hitch (23) are conveniently smaller than the length and width, respectively, of the longitudinal grooves (17) of the side walls of the pedestals (3) and crossbars (4); and between the concave fold (27) and the concave folds (28) of the central (25) and lateral arms (26) there is a conveniently larger transverse step than the width of said longitudinal grooves (17) of the pedestals (3) and crossbars (4).

There are also (figures 19 to 21) squares (29) with a flat wing equipped with means for its mooring on the back of a side panel (24) of the screen, and with its other wing susceptible to enter with a convenient clearance through said longitudinal grooves (17) of the side walls of the pedestals (3) and the crossbars (4). Figures 25 to 27A illustrate the placement of the side panels (24) by means of said clip hooks (23) and said squares (29); as figures 27 and clearly illustrate 27A, the clip hitch (23) penetrates one of the grooves (17) and by pressure the elastic flexion of the central arms is achieved (25) and lateral (26), until reaching the final situation (figure 27A) in which the concave fold (27) and folds (28) are locked in the longitudinal edges of said groove (17); this maneuver is facilitated by the squads (29) that begin penetration into another slot of the same row or parallel row (for clarity of the representation in these figures have been considered rows different) before the pressure to flex must begin  said arms (25 and 26).

Another feature of the invention consists in that along the bottom of the socket (1) (figures 28 and 29) and the coronation (2) (figures 30 and 31) there is an alternate sequence of wide holes (32) and longitudinal perforations (33); the holes (32), to facilitate the passage of cables and pipes; the perforations (33) for arranging tie means respective to the floor and ceiling of the structure installation enclosure.

Another feature of the invention consists of (Figures 32 and 33) in which along the funds of the lower (5) and upper (6) extensions there is a uniform sequence of holes (31) that are attached with a longitudinal opening (30) practiced at the bottom of the pedestals (3); its purpose is enable its mooring to the pedestal (3).

It is also planned to make structures with profiles of parallelepiped tubular section in which in their opposite faces are practiced similar operational die cuts as the said trapezoidal windows (9) and with, functionally, the same performance.
