FOLDING TELESCOPIC PREFABRICATED UNITS FOR NON-LOADING WALLS.

TECHNICAL FIELD. The present invention relates to the field of trusses of prefabricated partitions and, in particular, to prefabricated truss units for building interior and exterior walls not carrying loads that are telescopic and that are folded for easy transport and installation. Previous Technique According to existing methods, interior wall partitions that do not support loads to divide spaces in office buildings, and non-load bearing exterior walls, are constructed using wood or metal framing members that are measured and cut to length. The vertical components (uprights) and the horizontal components are fastened to each other and to the load-bearing structure, and holes are cut or drilled in the vertical members to accommodate wiring and piping. Such construction methods require experienced operators in the place of installation due to the measurement and subjection that are required, and they require a lot of time and are of high cost. To reduce the time and cost required for the construction of non-load bearing partitions, attempts have been made to provide prefabricated trusses that can be manufactured outside the installation site and easily assembled at the installation site to form a dividing wall. For example, U.S. Patent No. 3,078,968, issued February 26, 1993 in favor of Harvey Aluminum Inc., discloses an arrangement of prefabricated partitions, however, such provisions have not been generally accepted because They are extremely complicated. Revelation of the Invention. The invention provides a unit of prefabricated trusses for building non-load-bearing walls and partitions. The framing units have vertical uprights that either pivot relative to the horizontal members, to allow the unit to be folded, or telescoped to allow the unit to be raised to fit the space between the roof and the floor without measuring or cutting in height. Therefore, the invention provides a prefabricated truss unit for constructing a non-load bearing wall or partition comprising: a) a lower horizontal member; b) a superior horizontal member; c) a plurality of vertical members hingedly fastened at their upper end and at their lower end respects the upper horizontal member and the lower horizontal member; wherein each of the vertical members comprises an internal member adapted to slide within the external element. The invention also provides a method of construction of a non-load bearing partition between a floor and a roof, comprising: a) providing a prefabricated framing unit for constructing a non-load bearing wall or partition that comprises: i) a lower horizontal member; ii) a superior horizontal member; iii) a plurality of vertical members fastened hinged at their upper end and at their lower end respectively to the upper horizontal member and the lower horizontal member; wherein each ver- tical member comprises an external element and an internal element, the internal member being adapted to slide within the external element; b) place the lower horizontal member in position on the floor; c) raising the upper horizontal member to a position with vertical members vertically aligned in general; d) holding the lower horizontal member in position on the floor; e) raising the upper horizontal member until it contacts the roof, thereby causing the inner vertical member to slide relative to the external vertical member; f) holding the upper horizontal member in position to the ceiling; and g) holding the outer vertical member and the inner vertical member; Brief Description of the Drawings.

Detailed Description of the Invention. With reference to the accompanying drawings, the prefabricated truss unit 10 comprises horizontal members 12 and vertical uprights 14. A standard truss unit 10 is designed to fill a space of 2438 mm by 1219 mm when it is fully raised and extended. To allow certain flexibility, the extended height as shown in Figure 4 is 2464 mm, as explained below. The posts 14 are hingedly connected to the horizontal members 12 on hinges 16, which are typically metal screws. The horizontal members 12 are preferably of U-gauge galvanized iron profile 28, the lower member 12 forming a U-profile of a width of 92 mm and a depth of 27 mm, and the upper member 12 forming a U-shaped profile. a width of 89 mm and a depth of 27 mm. The posts 14 comprise external members 20 and internal members 22 as shown in Figure 4. With reference to Figure 7, the external post members 20 are preferably 92 mm wide and 35 mm deep and the members of Inner studs 22 are 89 mm wide and 27 mm deep, thus allowing the inner stud members 22 to slide freely within the outer stud members 20 to allow extension and refraction of studs. 26 Prepunched service hatches are provided on internal and external mounting members 20, 22 for wiring and plumbing. As shown in Figure 4, the internal and external stile members are preferably each approximately 1362 mm in height so that with an extruded height of 2464 mm there is an overlap B of approximately 279 mm. Figure 5 illustrates in detail the connection of the uprights 14 to the horizontal members. The screws 16 hold the uprights 14 to the horizontal members 12 to allow relative pivoting. The upper end 30 of the internal post members 22 is positioned so that the corners 31 contact the member 12 to limit the rotation of the post beyond a right angle with the horizontal member. The upper end 30 of the internal mounting members 22 is arranged at an angle, according to an angle C of approximately 15 ° to allow installation in non-parallel walls and ceilings where the height of the vertical stops will be unequal. The lower end 32 of the external post members 20 is also positioned so that the corners 32 make contact with the member 12 to limit the rotation of the post beyond a right angle with the horizontal member 12. A short shoulder at the corner 34 is provided to provide additional support to the upright. The lower end 32 of the outer pillar members 20 is arranged at an angle of approximately 15 ° in the opposite direction to thereby allow a variation of up to 30 ° from the horizontal to adapt to non-parallel floors and ceilings where the height of the vertical uprights will be uneven. To install a partition using the invention, the truss unit 10 is manufactured outside the installation site and is transported to the installation site in folded condition as shown in figure 1. The location for the wall partition is marked on the floor with chalk, tape or the like , and the lower horizontal member 12 is placed in position on the floor. The upper horizontal member 12 is taken and raised to the position shown in Figure 3 with the vertically aligned uprights. The lower horizontal member 12 is held in position on the floor by means of screws, nails or the like. The upper horizontal member 12 is taken up and raised vertically to the position shown in Figure 4, causing the inner pillar members 22 to slide outwardly from the outer para-member members 20, until the upper horizontal member 12 against the ceiling (not shown). The upper horizontal member 12 is then held in position to the ceiling by means of screws, nails or the like. Then the outer mirror member 20 and the inner pillar member 22 are fastened by means of screws or the like in the superposition area B. Then the required sheeting can be attached to the frame unit to complete the partition. Magnetic plating can be used which consists of panels having integral magnets for linking the iron framework of the invention, for the quick installation and dismantling of the wall plate. It should be understood that the invention can be adapted to uneven floors and ceilings since the uprights 14 can be extended to different lengths, with up to a variance of 30 °. The vertical dimensioning of the unit is achieved automatically without measurements or cuts that require a lot of time. Other sizes of units, (for example 2,438 mm by 610 mm) are also possible, as well as units that incorporate frames for doors and / or window frames. While a truss unit 10 with four uprights 14 is illustrated, the fourth upright can be omitted to avoid duplicating uprights in adjacent truss units when installed, or a number of vertical uprights can be removed within the scope of the invention. . Various related elements can be used to increase the utility of the present invention. For example, a foldable telescopic head unit 40 shown in Figs. 8 to 10 facilitates the framing of door or window units. The head unit is constructed with the same types of materials as the frame units 10. It comprises upper horizontal members 42 and inferiors and vertical members 44. The unit is designed to fill the space on a door or window frame and It will overlap with the width of the door or window by approximately 22 mm on each side. The high height is adjusted from 3.43 mm to 561 mm. For openings wider than 914 mm. one or more additional telescopic vertical members can be used. The vertical members 44 are pivotally connected to the horizontal members 42 on hinges 46, which are typically metal screws. As in the case of the uprights 14, the vertical members 44 consist of an external member 48 pivotally connected to the lower member 42 and an inner member 50 pivotally connected to the upper member 42 which slides on the outer member 48. The The head 40 is installed in the same manner as the truss unit 10, and is manufactured outside the installation site and transported to the site in folded condition as shown in Figure 8. The lower horizontal member 42 is put into position on the frame of the door or window. The tabs 52 are superimposed on the adjacent truss units. The upper horizontal member 42 is taken and raised to the position shown in Figure 9. Then the lower horizontal member 42 is held in place by means of screws, nails or the like. The upper horizontal member 42 turns and rises vertically to the position shown in Figure 10, causing the inner pillar member 50 to slide outwardly from the outer pillar member 48, until the upper hontal member 42 strikes the roof (not shown). Then the upper hontal member 42 is held in position to the roof by means of screws, nails or the like. Subsequently, the external post member 48 and the internal post member 50 are fastened by means of screws or the like in the overlapping area, and then the required sheeting can be linked to the head unit. Figure 15 illustrates a telescopic post 50 for use in conjunction with the invention, which has an internal element 62 that slides inside the external element 64. Service openings 66 are pre-cut in the elements 62, 64. Caps are provided ends 68 with holes 69 pre-drilled for screws. When a partition wall being constructed requires a framing unit 10 that is of a length less than a standard length, the assembly 60 can be installed to the required length by screwing the end caps 68 into the upper channels 12 and bottom of the truss unit 10, and the excess length of the truss unit 10 is cut. Similarly, the upright 60 can be installed at a location in the truss unit 10 to frame a door or the like. Prefabricated truss units using a principle similar to what is shown in Figures 1-7 can be used as a load-bearing roof truss, as shown in Figures 11-14. Folding telescopic truss units for a roof truss are also constructed with galvanized iron profiles but require heavier gauge iron to withstand loads, typically 18 to 20 gauge. The type and thickness of iron needed will be evident to those skilled in the art. The matter. Figures 11 and 12 show a roof truss 70, comprising peaks 72 'joined by hinge 73, and internal and external cross members 74, 76 attached to members of peaks 72', 72 by means of hinges 75, 77 respectively. The inner cross member 74 is telescoped inside the outer cross member 76. The overhead truss is transported in folded condition shown in Figure 11. For mounting at the installation site, the peak members 72, 72 'are raised making the inner cross member 74 slides within the cross member 76. The peak member 72 'is a little narrower than the peak member 72 to allow it to fit within the profile of the peak member 72 in the vicinity of the hinge 73. Similarly, the cross members 74, 76 are a little narrower than the peak members 72 ', 72 to allow them to fit within the profiles of the peak members 72' in the vicinity of the hinges 75, 77 The reinforcing members 78, 78 'and 79 are then screwed-on to the respective beams by means of screws 71. As shown, it is shown to fix the truss and to fix the cross-piece 74 on the cross-member 76. A roof truss 80, shown in figures 13, 14, is similarly constructed, comprising peak members 82, 82 'joined by hinge 83, and an inner cross member 84 and an outer cross member 86 attached to the peak members 82', 82 by means of hinges 85, 87 respectively. The cross member 84 is telescoped within the outer cross member 86. To mount the overhead trusses, the peak members 82, 82 'are raised, causing the inner cross member 84 to slide within the cross member 86. Then the reinforcing members 88, 88 and 89 are bolted by means of screws 81 to the respective beams as shown in Fig. 1-7, can be used as an arrangement of the same. load-bearing floor rails Folding telescoping truss units for an arrangement of floor rails are constructed in the same manner as for the wall-partition truss units described above, but require a larger gauge iron to withstand loads, typically an 18 to 30 gauge. The required type and thickness of iron will be apparent to those skilled in the art. The size of the floor-frame truss units would be also larger, typically with a width of 2,438 mm and a length of 4,876 mm 7,014 mm or 9,752 mm. The flooring truss units would be assembled outside the installation site and transported in folded condition. Once they are in the place of installation, they would be unfolded and telescopied to the required size, placed horizontally on the edge and nailed or bolted to the support beams or walls, which would be the load-bearing beams or the Foundation walls as in current construction methods. Then the telescopic uprights would be screwed together to fix their length as in the case of the truss units of partition walls. As will be apparent to those skilled in the art based on the pertinent disclosure, many alterations and modifications are possible in the practice of the invention, without departing from the spirit and scope thereof. For example, different shapes can be selected in cross section and different sizes for the uprights and the members are horizontal, and different materials are suitable for the components. Accordingly, the scope of the invention should be interpreted in accordance with the substance defined by the following claims.
