Set of metal sections suitable for constructing movable partition walls and related movable partition wall

Abstract: A set of metal sections has been invented for the construction of movable partition walls (80;88;102) that are practically smooth externally with no irregularities; there is a first metal section (1;10;12;17) constituting uprights for supporting panels (81;103) of said partition walls (80;88;102), that comprises a tubular casing (2;13) provided with joining means (3,4;14,15) suitable for engaging with connecting means (18,84,86;90,91,92;21;34;40) fastened to substantially internal surfaces of said panels (81,103), so that in the finished movable partition walls (80;88;102), said uprights (1;10;12;17) remain inside the layer formed by said panels (81,103).

Description: The present invention relates to a set of metal sections suitable for constructing movable partition walls, and related movable partition wall. In buildings used as offices, laboratories, workshops, provided with open spaces, it is possible to obtain spaces separate from the surrounding ones by means of movable partition walls. The movable partition walls are mounted on the spot and are provided with doors, where necessary. Generally the movable partition walls are constituted by panels, in wood, compressed-wood chips, or glass, and by supporting frames, formed by metal sections that constitute uprights and beams. The metal sections are provided with seats suitable for housing the edges of the panels, so that, after assembly, the panels appear framed by the uprights and by the cross-beams. Thus in a finished partition wall the panels are alternated by the metal sections of the uprights, that remain in full view. The uprights in full view create a non-uniformity on the surface of the partition walls and weigh its line down, with an unpleasant aesthetic effect. DE-A-25 11 690 discloses a section bar comprising a tubular body provided with C-shaped channels formed by elastic tangs. The front and rear C-shaped channels are capable of housing screw heads which are previously fastened to wall panels or to a couple of L-shaped section bars capable of supporting a glass panel. The section bar of DE-A-25 11 690 has the following drawbacks: Each channel allows an only element, i.e. an wall panel or a glass section bar, to be fastened by means of respective screws to the section bar. Therefore, the wall assembly is laborious. The screw heads are not firmly fastened in the respective channel due to the elasticity of the tangs. Thus, the screw haeds and the respective wall panel can vertically slide in the channel. A glass panel cannot be mounted in the section bar coplanar with a wall panel because it should be drilled for passing the screws. Screws provided with special heads embodying a stop are needed so that they project from the wall panel and engage the channel. FR-A-2 376 927 discloses an H-shaped section bar having two front and rear channels and two side C-shaped joining means. Wall panels are connected to the front and rear channels by means of a clip and a T-shaped section bar which cannot be coplanar with the wall panels. FR-A-2 643 700 discloses a section bar having sidewalls provided with holes which is connected to wall panels by means of an elastic C-shaped strip and two pins which are engaged by clips fastened to the wall panels. The holes in the sidewalls are needed for firmly fastening the elastic C-shaped strip to the section bar, however they weaken the section bar. The main object of the invention is a set of metal sections suitable for constructing movable partition walls, comprising uprights that allow panels to be assembled so that partition walls are constructed whose surfaces have a practically smooth finishing with no non-uniformities. Another object of the invention is a set of metal sections that allows the partition walls to be assembled with simple and fast operations and to obtain movable partition walls that are resistant and stable. The abovementioned objects are attained with a set of metal sections as defined in claim 1. The abovementioend objects are also attained with a movable partition wall as defined in claim 15. With a set of sections accomplished according to the invention, after the uprights have been assembled, the panels forming a layer are fastened by means of said connecting means that link up with substantially internal surfaces of said panels. In this way the uprights remain inside the layer formed by the panels and partition walls are accomplished that have an external practically smooth finishing with no irregularities. Moreover, many advantages arise from the provision of a cam-shaped plate which has the function of interconnecting element between one C-shaped joining means of a section bar and connecting means fastened to movable wall panels. Mainly, the cam-shaped plate allows a) fastening a couple of wall panels to a single C-shaped joining means of a metal section bar and b) connecting the couple of wall panels to the metal section bar in two ways: side by side or opposite. The first one is performed by means of a screw and an inverted-omega shaped section bar, the second one is performed by means of a screw, a plate provided with pins and spring fastening devices. Said two connecting ways are selectable according to the need, making easy and flexible the assembly of the wall panels and the section bar. Since the cam-shaped plate is engaged with interference with the rigid (not elastic) folded tangs of the C-shaped joining means, the wall panels are firmly fasten to the section bar in a preselected position by means of the cam-shaped plate. Therefore, sliding vertical movements of the wall panels are prevented. Furthermore, a structural glass panel can be assembled coplanar with the wall panels by glueing it to an L-shaped section bar which, in turn, is fastened to the cam-shaped plate by means of a screw, a plate provided with pins and spring fastening devices. The assembly of the movable partition walls is very simple and fast, because after assemblying the uprights, the subsequent fastening of the panels is made by means of said connecting means. In addition, the movable partition walls made in this way are especially resistant and stable. Sets of metal sections and partition walls made therewith will now be illustrated in the enclosed figures.

In Fig. 18 there is indicated as a whole with 76 an aluminium alloy metal section having a substantially U-shaped transversal section and comprising a transversal wall 77 provided with C-shaped joining means 78. Fig. 19 shows a movable partition wall, indicated as a whole with 80, comprising an upright constituted by the metal section 1 of Fig. 1, panels 81 of wood or compressed-wood chips, connecting means between the upright 1 and the panels 81, indicated as a whole with 82, and sealing strips 83. The connecting means 82 comprises cam-shaped plates 84, provided with a threaded hole 85, the metal sections 18 of Fig. 5, and screws 86. The plates 84 are fastened into the C-shaped joining means 4 of the upright 1, as shown in Fig. 20, and to these, with the screws 86, there are fastened the sections 18, holding the panels 81. In the sections 18 there are fastened the U-shaped covering strips, indicated with 87. As can be seen from Fig. 19, the movable partition wall 80 has a practically smooth finishing with no irregularities, since the upright 1 is located inside the layer formed by the panels 81 and is substantially covered by the same panels 81; the sections 18 are also substantially covered by the sealing strips 87. Fig. 21 shows a movable partition wall, indicated as a whole with 88, that differs from the movable partition wall 80 of Fig. 19 for the presence of connecting means, indicated as a whole with 89, between the upright 1 and the panels 81. The connecting means 89 comprise spring fastening devices 90 fastened to the panels 81 by screws, not shown, suitable for engaging with pins 91 held by plates 92, also shown in Fig. 23; the plates 92 are provided with holes, not shown, in which screws are inserted that make them integral with cam plates 84, like the ones of Fig. 20, in turn fastened to C-shaped joining means 3 of the upright 1. In this case the panels 81 are fastened to the upright 1 with the interposition of omega-shaped sealing strips 93. The movable partition wall 88, shown in Fig. 22, differs from that of Fig. 21 in that the panels 81 have finished edges 94 and for the presence of sealing strips 95 between the panels 81 and the upright 1. The movable partition walls 88 have a practically smooth finishing with no irregularities like the partition wall 80. In this case as well, the upright 1 is located inside the layer formed by the panels 81 and is thus substantially covered by the same panels 81, while sealing strips 93 or 95 close the spaces between the panels 81. Fig. 24 shows a connection between the movable partition wall 88 of Fig. 22 and a wall 150 of a building. To the upright 1 there is pressure-fastened a covering trim constituted by the metal section 70 of Fig. 16 and between this and the wall there is interposed an insulating plate 96. Fig. 25 shows a connection of the movable partition wall 88 to the surface of a wall 150, made by pressure-fastening on the upright 1 a covering trim constituted by the section 72 of Fig. 17 and interposing between this and the wall the section 76 of Fig. 18, sealing strips 97 and a regulator 98, known in itself. The regulator 98 allows the covering trim 72 to slide with respect the section 76, so that the distance between the upright 1 and the wall 150 is changed, to compensate for dimensional differences and out of plumb of the wall. Fig. 26 shows a connection between two movable partition walls 88, or a three-way joint made in the same way as the wall connection shown in Fig. 24. Fig. 27 shows an angle joint between two movable partition walls 88 placed at 90°, made by joining the uprights 1 by means of a metal angle 99 and cam plates and screws, not shown. Externally the joint is covered by an angle 100 of the same material as the panels 81; the angle 100 is fastened to the angle 99 by means of spring fastening devices 90 and pins 91, not shown, while internally between the partition walls 88 a sealing strip 101 is interposed. Fig. 28 shows a twin-panel movable partition wall, indicated as a whole with 102, connected to a partition wall 104 formed by just one panel. The partition wall 102 comprises an upright constituted by the metal section 1 of Fig. 1, glass panels 103 and connecting means 105 between the upright 1 and the panels 103. The partition wall 104 in plain, stratified glass, is connected to the upright 1 by connecting means 106. The connecting means 105 comprise the metal sections 21 of Fig. 6, spring fastening devices 90, pins 91, plates 92, cam plates 84 and screws 86, like the ones of Fig. 23. The sections 21 support the glass panels 103 with the interposition of sealing strips 107, and the spring fastening devices 90 are fastened to the sections 21 by means of cam plates 84 and screws 86; the spring fastening devices 90 engage with the pins 91 held by plates 92, fastened by means of screws and further cam plates 84 to the C-shaped joining means 3 of the upright 1. The connecting means 106, in turn, comprise the metal sections 28 of Fig. 7, that hold the glass panel 104 by means of sealing strips 107, spring fastening devices 90, pins 91, plates 92, cam plates 84 and screws 86, like the connecting means 105. There are represented diagrammatically reinforcement brackets 108 of the angle joints of sections 21 and 28. There are indicated with 83 and 109 sealing strips interposed between upright 1 and sections 21 and 28 and between the same sections 21 and 28. As can be seen from Fig. 28, the movable partition wall 102, in the area of the glass panels 103, has a practically smooth finishing with no irregularities, since the upright 1 is located inside the layer formed by the panels 103. In addition the upright 1 and the connecting means 106 illustrated allow a connection to be made between areas of partition wall with panels 103 forming one layer and areas of partition wall with a single panel 104. The movable partition wall 110, shown in Fig. 29, differs from that of Fig. 28 in that the glass panels 103 are glued by gluing means 111, such as an adhesive, to the metal sections 34 of Fig. 8, the panel 104 is formed by an insulated glass and is supported by the sections 42 of Fig. 10. Instead of the sections 34, the sections 40 of Fig. 9 may be used. Fig. 30 shows an angle joint between two movable partition walls 102 placed at 90°, made by joining the uprights 1 with a metal angle 99 and cam plates and screws, not shown. Externally the joint is covered by the metal section 46 of Fig. 12; the section 46 is fastened to the angle 99 by means of spring fastening devices 90 and pins like the ones of Fig. 23, fastened to the section 46, as shown in Fig. 28, and to the angle 99, while internally a sealing strip 101 is interposed between the partition walls 102. Fig. 31 shows a movable partition wall 102 provided with a glass door 112, having a frame 113 formed by metal sections. To the upright 1 there are pressure-fastened the metal sections 57 and 62 of Figs. 14 and 15 joined by means of a screw 115, so as to form an intrados or fixed frame 114 of the door 112. The hinges connecting the frame 113 of the door 112 to the intrados 114 are not shown. The switches fastened to the sections 57 and 62 are indicated with 116. Fig. 32 shows a movable partition wall 102 provided with a panel door 117, connected to the intrados 114 by means of hinges like the one indicated with 118. The parts that are the same as those of Fig. 31 are indicated with the same numbers. With the arrangement of doors shown in Figs. 31 and 32, wherein the intrados 114 is pressure-fastened to the upright 1, it is simple to move the doors from one position to another of the partition walls 102. In Fig. 33 there are indicated with 119 and 120 a floor and a ceiling of the room in which the movable partition wall 88 of Fig. 22 is assembled. The sections 51 of Fig. 13 are fastened to the floor 119 and to the ceiling 120, after interposing channel sealing strips 121. Between the sections 51 and the upright 1 there are inserted the H-shaped sections 43 of Fig. 11 and pressure devices 122 and 123, not shown in detail, as they are known. The pressure devices are used to adjust the height of the upright 1 and to create the sealing pressure between the floor and the ceiling, by using a star-shaped screwdriver, like the one indicated with 125 in Fig. 34, so as to make displacements in the directions indicated by the arrow 126. The pressure device 123 has a spring 124, used to maintain the sealing pressure even in the case of oscillations and vibrations of floor and ceiling. The H-shaped sections 43 are used to maintain the uprights 1 in position, to prevent their rotation with respect to the sections 51 and to distribute the pressure exerted by the pressure devices 122 and 123 on the upright 1 over a wider surface. After assemblying the upright 1, the plates 92 provided with pins 91 are mounted on it and on these the panels 81 are assembled by means of the spring fastening devices 90. As can be seen from Fig. 33, the upright 1, the beams 51 and the sealing strips 121 remain inside the layer formed by the panels 81 and are substantially covered by the same panels 81, so that the partition walls 88 have a practically smooth external finishing with no irregularities. Fig. 35 shows the assembly at different heights of shelves 128 in the upright 1 of movable partition walls 88, executed by means of brackets 129 and a rack-type element 130 fastened to the C-shaped joining elements 4 of the upright 1. Fig. 36 shows the assembly of cabinets 131 in the upright 1 of movable partition walls 88, by means of a bush 132 fastened to a wall 133 of a cabinet 131, a threaded pin 134 and a cam plate 84 fastened to the C-shaped joining means 4 of the upright 1. Figs. 37 and 38 illustrate the fastening to an upright 1 of a cross-beam 135 of a movable partition wall, constituted by the same section 1 of Fig. 1. A bracket 136 is fastened to the cross-beam 135 and is attached to a plate 137 fastened in turn to the same upright 1 by means of a screw 138 and a cam plate 84. The movable partition walls described above can be accomplished with uprights constituted by the sections 10, or 12 or 17 of Figs. 2, 3, 4, instead of the section 1 of Fig. 1. In the case of the sections 12 and 17, the panels 81 of the movable partition wall 80 of Fig. 19 can be fastened to the upright, applying the sections 18 to their partition walls 14 with self-tapping screws. In a manner similar to that shown for the upright 1, to an upright formed by the sections 12 and 17 it is possible to fasten the panels 81 of the movable partition wall 88 of Fig. 21, or the glass panels 103 of the movable partition walls 102 and 110 of Figs. 28 and 29. The examples of embodiments described above demonstrate the ease and simplicity of assembly of the uprights and of the movable partition walls accomplished according to the invention, as well as their extreme versatility.
