Description

Area, techniques

The invention relates to the construction, materials and method of manufacturing high quality, low cost buildings that are quick and easy to install. Such buildings consist of manufactured elements that can be quickly assembled without the need for skilled work, usually within three to five days, giving rise to a building whose appearance and high quality are comparable to a building constructed by traditional building methods.

BACKGROUND OF THE INVENTION

Currently there is a worldwide urgent need for residential construction. The current demand is about 250 million units. Traditional building methods never satisfy this need. What is required is a structure that is efficient and economical to produce affordable and durable residential buildings.

Many of these buildings are required in remote areas, with extreme climates, lack of skilled work, and without infrastructure. Typical examples are third world countries and Indian communities in northern Canada. Although these communities are cut off from the world as a result of vast distances, they are informed on television about the standard of living in the rest of the world, the level they strive for. Thus, it is not satisfied with a lower level product.

Therefore, efforts are being made to reach this market with a factory building. Some of the current offerings are technologically advanced, but are extremely inflexible because they cannot adapt to individual requirements. Some

-2of these buildings also have a strange, appearance of space age, page. On the lower to achieve better, the efficiency of adaptability is reduced, and economy, which is not acceptable after a cultural technology level can but at this level, so that little benefits are achieved over traditional construction methods.

Traditional ways of constructing frame buildings, if they already use wood or metal posts, usually involve delivering unprocessed building materials to the construction site and then building an open frame structure for each wall. These open frame structures are clad before or after standing. After positioning the frame, insulation is usually carried out either in the slits between the posts or as a foam filler applied to the frame. Vapor barriers are also used, independently of the frame position. The electrical wiring is routed to the exterior of the vapor barrier to which cut-outs must be provided to accommodate the drawers. Qualified craftsmanship is required for any installation of buildings made of unprocessed Building Materials.

Furthermore, a number of prefabricated buildings were designed. At reasonably low costs, there is a clear effort for assembled units, such as half-houses, but which are usually large and require special transport. These units often exceed the permissible dimensions on the roads and special measures must also be taken for their transport.

SUMMARY OF THE INVENTION

The basic philosophy of the present invention is the production of building elements that are so technologically advanced that they minimize the problems that are required for on-site assembly. Also all electrical and installation work, all measurements and cutting, fitting and testing are carried out

-3a control at the factory. Nevertheless, this system provides considerable flexibility in its design. The structural elements can be selected and reused for the construction of new buildings of various dimensions, shapes and functions.

The building has a high insulation level (R-30) and is lighter than other buildings of a similar size because building elements are easy to transport. They can be assembled by unqualified personnel, and no waste is to be disposed of.

These tasks are provided by a building system for a building having at least one room and consisting of portable prefabricated wall panels of mutually similar dimensions to form an outer wall, aligning the side edge of one wall panel, wherein the height of each wall panel, in an upright position, It essentially corresponds to the aforementioned room according to the invention, in which each wall unit comprises a rigid peripheral metal frame and a wall panel which has the same extent as the metal frame and which is attached to something. The rigid peripheral metal frame comprises pairs of metal frame members, one pair being located at each side edge of said panel, wherein thermal insulating compartments are arranged between the frame members of each pair, the frame members being in a vertical position where the wall member is erected, the pair of frame members of one wall piece is arranged connectable to the pair of frame members of an adjacent wall piece to form a composite support member.

The height of each wall unit suitably depends on the desired ceiling height. The standard ceiling height in Canada and the United States is usually 2.44 m (8 feet). In order to allow some overlap of the ceiling insulation, a panel of just over 2.44 m (8 feet), say 2.44 m (8 feet) and 76 mm (3) would be required.

As the ceiling insulation is very thick, it increases

-4 accordingly, the height of the wall panel, and if the height of the room is different, is set to the height of the panel.

The panels may have a width of 1.22 m (4 feet) and at least one wall panel may be provided with cut-outs for receiving elements of groups consisting of doors and windows. The building system may comprise at least one roof truss and a support member for accommodating the roof truss between a pair of said composite support members of an opposite pair of adjacent wall members. The support members may be provided with a U-shaped bracket having a base and two webs, wherein the base is adapted to pass through the thickness of the wall unit in the region of one frame member and each bracket web is attachable to both frame members to form a composite support member. and wherein each web is configured to be supported and connected to a U-shaped bracket. The U-shaped bracket base may be provided with a pair of downwardly spaced tips to define the bracket against the frame members of one of the composite support members.

The building system may comprise at least one ceiling panel the width of which is similar to the width of the wall panels.

Each roof truss may be provided with a guide track along the lower portion of its strip to support adjacent ceiling panels housed therein. The guide track may have a T-shaped shape, where the vertical web of the T-shape is adjacent to one side of the cross member of one of the trusses and the T-arm extends horizontally.

The building system may comprise a base with a supporting perimeter to accommodate the wall panels.

The building system may comprise a guide track to indicate a template for the arrangement of internal partitions, the guide track comprising guide members interconnected and arranged between the closed position in which they lie closely

Side by side for transport purposes, and an open position indicating said template, wherein the guide track is arranged attachable to the floor template in the open position. The guide track may comprise displaceable spacing elements at predetermined locations for the door openings. The building system may further comprise internal partition units, the lower edges of which are positioned in the guide track in its open position, the partition units comprising gypsum board panels that are sandwiched around the rigid metal plastic core panel, or the partition units may comprise steel frames.

DETAILED DESCRIPTION OF THE INVENTION

In FIG. 1 shows a general structural spatial and plan view of a building according to the invention. Roof trusses 10 made of cold-rolled steel are supported on wall units 12 resting on the floorboard 14. The wall panels 12 have a panel portion 22 which may be a plastic foam board and at least vertical frame units 18 made of metal and provided with in its thickness by thermal insulating partitions. The plastic foam additionally acts as a vapor barrier. The spacing of the roof trusses 10 is the same as the width of the wall panels, usually 1.22 m (48). The roof trusses 10 have, at each end, a foot 16 in the form of a downwardly facing yoke. The foot 16 carries the load

Roof trusses 10 of the wall panels 12 and thence to the peripheral members 20 of the floor panels 14. This allows the spacing of the structural elements to be larger than the industry standard of 0.6 m (24). Although the trusses 10 should be thicker, they are half, thereby reducing the labor costs required for their assembly.

By placing the trusses 10 at the same spacing as the width of the wall panels 12, the vertical load on the circumferential frame members 18 of the wall panels is reduced, as shown in FIG. 2 and no load is transmitted to the panel body. The upper belt 24 and the lower belt 31 of the trusses 10 are joined together by a foot 16 abutting a bent U-shaped metal shoe 30 whose webs extend over the wall unit 12. The shoe 30 is sufficiently rigid to evenly distribute the load to adjacent vertical circumferential elements 18 which together form the composition of the support members 32. No load is transmitted to the upper horizontal frame members 34 of the wall panels. A sheet metal bend 28 bent 90 ° around its vertical axis attaches the lower web 31 to both frame members 18 of adjacent wall panels. This means that the panel does not need any internal reinforcement. Any type of doors, windows or other openings can be placed in the slots 26 in the wall panels 12 without lintels, ties and scaffolding.

In FIG. 3, the shoe 30 is shown in enlarged scale. The base 41 of the shoe 30 is provided with bolt holes 36 through which the shoe 30 can be attached to the bottom web 31 or the crossbeam of the truss 10 and to the foot 16. Two legs 40 of the shoe 30 define longitudinally the truss on the wall panel. In the central portion of the shoe 30, the two indentations 42 are cut and protruding down like spikes. In the gap between these spikes there is a central rib of the wall panel connector that is aligned with the joint between the panels and which

-8will be described below. It serves to delineate the truss laterally so that the four lower projections (webs 40 and depressions 42) of the shoe 30 serve to accurately and automatically align the truss to the center of the joint between the vertical frame members 18.

The cut openings 44 of the depressions 42 occupy most of the width of the shoe base 30, leaving intact two relatively narrow rings 46 which reduce the cross-sectional area suitable for heat transfer, thereby helping to maintain the thermal cohesion of the building shell.

The wall panels can easily be positioned on the wood or concrete floorboard 14 simply by abutting the edge of one wall panel to the edge of the other panel. The thermal insulators, which will be described in more detail below, are arranged in the thickness of the frame elements 18, and consist of insulating lips 94A extending from one edge of the panel into engagement with the channel of the adjacent edge of the adjacent wall piece. These thermal insulating partitions can by their grip assist in the assembly of wall parts. Of course, it is important that the wall parts are joined together with a consistent degree of thickness so that the finished building is built on a square base. To this end, the system is provided with fasteners and fasteners 17, as shown in FIG. 4, which are positioned at regular intervals along the height of the frame elements 18 of adjacent panels. Each connecting and fastening element 17 consists of a small plate 19 with a through hole 21. A bearing pin 2.3 extends from the surface of the wall element frame 18 so that the plate 19 is rotatable to cover the joint between the wall pieces 12. The plate 19 has a bevel cut 25 facing downwards. The notch 25 engages with a pin 27 extending from the surface of the adjacent wall piece 12. · The bevel angle of the notch 25 is such that when the plate is folded down by rotating around

9, the pin is pressed in close proximity with the bearing pin 23. and the wall parts 12 are clamped together.

The wall pieces 12 can usually be seated in metal floor plates 29 on the floor plate 14.

As is clear from FIG. 4 and 5, the ceiling is composed of composite panels 48 consisting of gypsum cement boards 50 glued to the foamed plastic core 52. Thus, sufficient rigidity is provided to bridge the increased distance between the roof trusses. The trusses 10 span the entire building space from one outer wall to the other outer wall. Such a span may produce measurable deviations when the trusses 13 are loaded. The trusses 10 may be conventional wood or metal trusses, but are particularly provided with metal frames 31. The trusses 10 may be particularly in the embodiment as shown in FIG.

5, where a portion of such a rectangular beam is shown to abut with respect to respective first sides 13A. 13B forming a vertical beam arm, wherein the beam overhang forms the roof rafter 39 and the respective second sides 31 are aligned as a folded beam of the beam. The frames may be joined together by connecting elements 15.

The elements necessary to interconnect the trusses to ensure their stability are attached to the trusses during production, so that the number of individual places that must be handled on the construction site is minimized. As shown in FIG.

6, the purlins 37 are hinged to the upper strip 39 of the truss so that they can be folded for transport and unfolded to engage the upper strip of an adjacent truss during assembly to ensure proper spacing. Similarly, diagonal braces 35 are attached to the upper belt 39 by pivot pins so that after installation of the truss

The beams can be spaced to attach adjacent trusses, while triangulating the perpendicular row of prisons and creating a structure of high rigidity.

Similarly, the spacing members 41 may be attached to the sides of the central vertical member of the truss so that during assembly they may rotate to engage the nearest truss, to maintain the spacing of the bottom members of the truss. The respective central vertical elements of the gable end of the walls have two such spacers with separate pivot pins. Their attachment to the adjacent truss creates a triangular shape of the shield and maintains its vertical alignment.

Roof plates can be attached to metal roof trusses 10 by a suitable roof clamp system.

Since the trusses 10 carry a ceiling that is firmly attached to the crossbars, the load on the ceiling could then be transferred to the crossbars that are not designed for such a load. One way to avoid these difficulties is to provide composite ceiling rails that can slide towards each other on the top of the partition so as to allow independent sliding of the ceiling. The disadvantage is that there is a variable gap between the wall and the ceiling for which additional flashing is required.

The present invention optionally provides a sliding connection between the truss and the ceiling so that the ceiling and the wall remain in a fixed position relative to each other. A T piece 54 with protruding arms 56 is attached to the bottom web 31 of the truss 10 and extends between opposing wall pieces 12. The T piece 54 is attached to the bottom web 31 by a series of screws 58 engaging grooves in the web 57 of the T piece 54. The overlapping arms 56 and hence the ceiling are in a horizontal position when the truss is not loaded. As soon as the truss is loaded

As the lower belt 31 is moved downward, the bolt slips into the groove and the ceiling supported by the crossbars remains rigid, and there is no load on the crossbars.

The ceiling panels 50 are mounted by placing the panel on a projecting arm 56 of the T piece 54, which then carries one edge of the ceiling panel 50. The other edge of the ceiling panel 50 is then screwed to the next T piece. A rigid insulation 66 is attached to the opposite side of the T piece.

In FIG. 8, there is shown a system according to the invention comprising inner walls 70 and wall parts 12.

The wall parts 12 are fastened to the floor 14 by retaining clips 71 and retaining clips 75, as best seen in FIG. 8A. The retaining clip 71 consists of a Z-shaped strip having two webs 77, 79 extending at right angles from the rib 81. The rib 81 has a length similar to the thickness of the wall angle 12. The clamp is positioned by its rib 81 so that it is aligned with the upper surface of the floor panel 14 such that one wall piece 12 is held on its rib 81 so as to abut the raised web 77 and the other wall piece 12 is at right angles to its inner surface and abuts the edge of the raised web 77. 79 retains against the edge of the floor panel 14. The retaining clip 71 is firmly fixed in position, for example by means of a screw. The wall member 12 is then positioned with its certain surface against the edge of the web 77. An additional positioning guide 85 may extend from the central portion of the web 81. Once the wall panel is precisely positioned, the retaining clip 75 may be firmly attached between the outer frame element 18 of the wall panel 12 and the frame 83 of the floor panel 14. Before the retaining clip 75 is fixed, hingedly mounted to frame member 18 or frame 83.

The partitions 70 can be seated in their position completely and accurately without taking measurements at the construction site and without marking their positions on the floor. The inner partitions 70 are

Each guide element 74 is pre-cut in the factory for the partition for which it is intended, and the individual parts of the guide elements 74 are hingedly connected to form guide tracks 72 that precisely define the intersection points of the bars. The guide tracks may be connected by grooved joints which are color-coded to ensure their precise positioning.

The hingedly connected subgroups of the guide elements 74 may be folded into compact bundles to facilitate transportation. In FIG. 9, there is shown a bundle of guide track 72 that is partially unfolded.

The removable disposable spacer 76 in the door openings maintains the spacing and alignment of the guides. Coded graphical symbols along the guideways indicate the panels for which the guideway is intended and the location of electrical items such as sockets and switches.

In FIG. 10 shows the assembly process of the crossbars 70. After placing the floor guides 72 on the floor 14 and screwing them into position with screws 78, portions of the shallow but otherwise similar ceiling guides 80 are screwed to the ceiling, just above the floor guides. The sliding post with machined ends for engagement with the floor and ceiling guideways and the built-in alignment mechanism ensures that these elements are aligned.

The overhead guide track has a built-in electrical cable duct 82, in which wired cables with attached electrical boxes are inserted, wherein the boxes for switches and sockets hang down in their correct position.

The partitions 70 consist of sandwich panels with gypsum-cement front panels 84 connected to a foamed plastic core 86 or steel spacers

-13prvkami. The core is recessed away from the periphery of the panel to provide space for the guide track and other connecting elements. To set up the partition, the bottom part must first be installed. into the floor guide track. The partition is then lifted to a vertical position and lifted until it touches the ceiling with the cobbled ceilings passing into the space formed in the core. It is screwed in place in its position by the screw 86 and the slot at the bottom is covered by the base plate 88.

11, the outer wall panel 12 is shown. The vertical frame members 18 consist of pairs of cold-rolled C-shaped steel galvanized parts 90. A foamed insulating panel 90 is inserted into the open portion of the C-shaped parts 90 with its edge. . The C-shaped parts 90 are separated by vinyl extruded plastic moldings 94, 94A, which form thermal insulating partitions between the steel members and the exterior and interior parts of the building.

The plastic molding 94 has the shape shown in FIG. 9, and the elongated part is extruded from C-shaped plastic. Its curved edges 97 are hooked into adjacent curved edges 95 of the C-shaped steel piece 90, and are joined together. The curved edges 95 of the C-shaped steel part 10 snap into the plastic molding 94 and abut the plastic molding 94, which locks them in this position and forms a channel 99 between the steel-shaped moldings 97 of the protruding ribs 96

C.

The plastic molding 94Ä between the C-shaped steel panels of adjacent panels (see FIG. 10) and the other edge of the single panel shown in FIG. 9, the tongue 98 extends from the space ribs 96A. Pen 98 fills the gap between the C-shaped steel pieces of the frame element 18 of the adjacent wall unit and helps to level out

-14 panels as they are built and form a fixed stop between the C-shaped steel pieces. The complete joint can be seen in FIG. 10, which is a cross-sectional view of the composite support member 32, which itself consists of two frame members 18, each consisting of two C-shaped steel parts.

The C-shaped steel parts can be used on the corner of the building. Since the wall portions have to be aligned at right angles to each other, additional C-shaped steel frame members can be placed on the surface of one corner panel adjacent to the C-shaped steel frame member 18. 18A of a corner piece. One of the wall panels 12 in the corner portion is suitably narrow compared to the other panel. One of the corner pieces may be provided with a transverse stiffener to detect that the corners are rectangular, thereby helping to form the corner precisely.

The cap-like reinforcing channels 100 are connected to the inner surface of the panel to support the inner end surface. The stiffening channel 100 closest to the plastic molding 94A is fixed by means of a shaped groove 195 so that it is easily removable. The end portion 197 of the rib 199 of this reinforcement channel is extended over the webs. The elongations are bent inwardly by 75 ° in the lower part and by 15 ° in the upper part, and are bored for the screws so that the selected reinforcement channel can be re-screwed to the panel and screwed to the floor at an angle of approximately 75 °. This attachment of the reinforcement channel forms a reinforcement which ensures the vertical position of the walls when the roof trusses are raised, and in strong winds. When the roof system is assembled and reinforced, the reinforcement channels are removed and moved to the wall panels to support the inner end surface. Thus, the reinforcement channel can

-15 perform a dual service, such as a vertical reinforcement, when the structure is mounted. The reinforcement channels may also be provided on the inner surface of the wall unit 12 to additionally support the dry wall. Such reinforcement channels may be positioned with the ribs aligned with the inner surface of the wall unit 12 or may be spaced from the wall (see FIG. 13).

The connection between the two wall panels 12 is shown in FIG. Here it is shown that the tongue is inserted into the groove between the C-shaped steel parts of the adjacent unit and the main reinforcement channel 100 is shown in its forward position attached to the inner end surface 104. The pivot tab 102 now moves forward to overlap the frame member 18 nearest the the wall unit 12, and by screwing it to the frame member 18, the two units 12 are joined. A similar pivot bracket connects the outer surfaces of the panel frames.

The plastic molding 94A is shown in enlarged scale in FIG. It has a rib 106 across the projecting portion that is aligned with the joint axis between the units. Thus, lateral loads are transmitted between the inner and outer steel frame members. The rib acts as a short pillar, so it is reinforced in the middle section to withstand bulging caused by compressive loads. At the ends 108 of the web 106, the thickness decreases symmetrically. This directs lateral forces to the center of the rib and limits the bending of the rib due to eccentric loading.

The tongue 98 of the plastic molding 94A is sized to slid flush between the curved edges of the C-shaped steel piece surrounding them. Near the end, the width of the tongue 28 increases, resulting in a bulge 101 for interference fit between the C-shaped steel parts 90 of the closest wall part 12. This pressure causes the central part of the walls of this outlet to rotate

The tapered portion of the rib acts as a joint. Rotation causes the sides of the bases of this projection to press against the bands of channels framing the first panel, creating an airtight seal between the panels and between the interior and exterior of the building.

Thus, the combination of plastic molding and steel channels creates a single thermal unit, a vapor barrier, an airtight barrier, a fastener for steel frame members, a load transfer device, and a positioning pen for aligning the panels as they are assembled.
