Definitions

  • This invention relates to interlocking factory-made structural components, particularly extruded plastic components, for assembly by unskilled labour into a building.
  • PVC Polyvinyl Chloride
  • plastic based wall panels are desirable, because of their resistance to weather, to impacting and to abrasive forces, because they have a good loading resistance relative to its weight, a very high resistance to the destructive action of chemical agents and a good resistance to combustion, rust, salt, insect damages, and rot.
  • These plastic panels apply not only to domestic buildings or houses, but also to industrial, commercial and institutional buildings, and not excluding gazebos, partitions, sound barriers along highways, farm buildings and barns, and sheds.
  • Canadian patent application No 2,070,079 published 30 November 1993 in the name of Vittorio DE ZEN discloses a building constructed of extruded, thermoplastic, structural components.
  • the building is based on a system of factory-made components developed in such a way as to include all the components required for the assembly on the building site of a house with unskilled labour.
  • the extruded modular components are edgewisely interlocked to one another to form continuous, flat wall panels for forming the upright walls and roof parts of the building. More particularly, the side walls and roof panels are said to be configured to be connected into the housing structure by interlocking mating engagement with adjoining members so that they can be assembled without the use of tools.
  • Each wall panel is hollow, is made from PVC plastic material, and consists of spaced exterior and interior walls connected by transverse webs forming internal cells.
  • Such a wall panel system is lightweight and very easy to assemble by unskilled labour. It appears basically as a casing into which concrete is poured to form smooth, aesthetically appealing interior and exterior plastic wall faces which require minimal maintenance compared to houses built according to different standards.
  • the internal cells can then be filled with uncured (liquid) concrete and ⁇ or a flowable thermal insulation material.
  • a self-supporting structure can be erected and anchored to a base and converted into a permanent and sturdy structure.
  • the De Zen structural components as disclosed include extruded hollow panels, extruded hollow pane box connectors, extruded hollow beams and adapters, and extruded panel connectors. All these structural components are factory made, so that they can be assembled on the building sites by unskilled workers in a short period of time. Interior and exterior doors, windows, electrical and plumbing lines, cupboards, and other building elements can be accommodated by this system.
  • NAFTA North American Free Trade Agreement
  • United States patent No 3,992,839 issued 23 November 1976 to the Ethyl Corporation also discloses hollow extruded wall members, which are interconnected by transversely extending integral male and female connectors. More particularly, each wall member includes two main parallel wall panels spaced from one another by the transverse connectors.
  • the male connector forms an arrow shape stud, while the female connector forms a complementary socket.
  • the male and female connector elements interlock horizontally with one another in snap-on or clipping, generally unadjustable fashion, along interconnecting axes being orthogonal to that of the parallel (interior and exterior) side wall panels. Additional open tubular corner connector beams are provided, to interlock two adjacent wall members at a 90° degree relative to one another.
  • the gist of the invention is to provide a system of lightweight plastic building wall and roof modular components for building construction, which may be stacked in a very efficient fashion in their disassembled state so as to take the smallest loading volume during shipping.
  • An important object of the invention is that said modular components be of easy assembly by unskilled labour.
  • a general object of the invention is to provide a building system combining home country state of the art technology with local labour and locally available building materials (usually concrete), wherein the total project cost for a building unit be very low.
  • Another object of the invention is that the building system consist of several plastic components which will be used as casings for receiving and supporting therein the concrete.
  • An object of the invention is to improve upon published Canadian patent application No 2,070,079, supra.
  • each structural component including an elongated rigid sheet member provided with at least two integral lengthwise edgewise rail members, said structural components including first flat wall structural components and second elbowed corner structural components, wherein a few of said structural components releasably slidingly interlock with one another about their said rail members to form a hollow elongated panel; wherein each said hollow panel defines a body, including a flat exterior face and a flat interior face, and circumscribing a generally closed inner enclosure cell, said inner cell for receiving concrete to be poured and said hollow panel body adapted to withstand the load of a column of concrete poured therein; said sliding interlock engagement between said few structural components forming said hollow panel defining continuous lengthwise adjustment means for one said structural component relative to the other of said few structural components, said hollow panel releasably interlocking with adjacent hollow panels successively to form a continuous wall structure; and wherein said structural components in
  • thermoplastic material used in said structural components is polyvinyl chloride, admixed with at least one of the following reinforcing and stabilizing material: mineral fibres and filling materials.
  • Each said first structural component could further include additional lengthwise rail members, located intermediately of the first mentioned rail members; and further including at least one third structural component, being of cross-sectionally U-shape and having a pair of lengthwise edgewise flanges, said flange slidingly adjustably releasably engaging said additional intermediate rail members of a given said first structural component wherein said first and third structural components become interlocked; and wherein a generally closed channel is defined by said third structural component within said inner cell of a said hollow panel member, for free lengthwise passage of electrical lines.
  • thermo-setting plastic extrusions Such a prefabricated building construction system uses thermo-setting plastic extrusions. This system has been conceived for the construction of low-cost buildings and enable production of all the structural components on a large scale.
  • plastic based extrusions will be factory-made, being precut and prelabelled to be assembled on the building sites by unskilled labour in countries where demand for this type of building is high.
  • the wall extrusions are thereafter filled with concrete, while the extrusions forming the roof may be filled by regular concrete or by concrete mixed with polystyrene pellets which will permit the increase of the thermal ratio of the roof while decreasing also the roofing weight.
  • the extrusions can be stacked in a compact fashion, so as to reduce the shipping costs.
  • These buildings will therefore be quite economical and may be sold in all developing countries. This building system will use state of the art techniques for the structural plastic components in the home country factory, while an unskilled labour force and local concrete will be used on the building sites.
  • This building system is in fact a system of wasted casing, which may also be used for manufacture of a wide variety of structures such as fences, docks or privadas.
  • the buildings manufactured with this system are for all practical purposes built from monolithic ferro-concrete. They will therefore be resistant to earthquakes, termites, corrosion, rot, hurricanes, and generally speaking to damaging weathering action.
  • the wall and roofing extrusions have been developed so as to resist to concrete expansion during setting thereof.
  • the extrusions are assembled together so as to constitute a hollow wall by sliding same vertically from the top down, adjustably one into the other. Bores are made in the extrusions forming the web of the wall, so as to allow concrete to seep from one cell to another so as to make a monolithic wall.
  • reinforcing steel rods may be mounted to the base and to the top of the wall, to improve resistance of the concrete.
  • auxiliary extrusions are envisioned, so as to constitute the outer corners of the L-walls, the T intersections of the walls, the top and bottom sills, the roof soffits, and the extrusions which are used as adaptors for the doors and windows.
  • the system is a complete system including false frames to receive windows and doors, a roof frame system moulded in place thanks to a fibreglass casing (or with wooden beams), together with all the adaptors required for constituting the complete envelope of a building.
  • the extrusions have been developed so as to support therein the load of concrete.
  • the main extrusions may be made from recycled PVC. A thin layer of coextrusion will then be made in coextrusion over the exposed surface of these extrusions.
  • the extrusions may be deep-dyed or may be painted thereafter.
  • the whole system is conceived and controlled by computer. This enables to make the components on a large scale, but also to personalize each of the buildings according to the particular needs of the clients.
  • CAO-FAO computer conception and manufacture enables excellent inventory management and follow-up of working and shipping schedules.
  • the building components are characterized in that they are made from a plastic material, preferably extruded PVC; that they are finished on both sides, so that no outer or inner coating is to be installed thereafter; that the PVC extrusions interlock into one another so as to make a hollow wall ready to receive concrete; that some of these components carry therein channels to receive electrical lines which will be concealed in the walls and roofs; that a low number of different components will be required to make a building; that these building components may have varying textures and colours; and that the components are of modular dimensions, the dimensions of the doors and windows having therefore to conform to these component dimensions.
  • a plastic material preferably extruded PVC
  • House 20 illustrated in figures 1-3 is constructed according to the teachings of the invention, and includes upright side walls 22, a sloping roof 24, and a ground basement concrete flooring 26 cast on the building site. To the peripheral edge of the concrete flooring 26, there is mounted a lower sill, which can receive the wall extrusions (as detailed later). To accommodate windows 74 in the side wall 22, window apertures 28 should be made in the side wall 22, into each of which is mounted a window frame assembly 30. The window apertures 28 may be made by selectively sectioning at the home base factory the extrusion panels at different lengths. A large door opening 32 should also be made through side wall 22, for hingedly mounting therein an access door 84 (fig 14). Elongated rafters 34 support the two diverging roof sections 24a, 24b, over the top ends of the house side walls 22, while the concrete ground basement flooring 26 supports the bottom ends of the upright side walls 22.
  • Figures 4-5 suggest how the roof 24 is supported by the side walls 22 of the house 20.
  • the front walls are covered by a top sill 38 in which is mounted a shim 36, to accomodate the fact that the roof does not make a right angle with the building side wall.
  • the roofing elements 52 and 64 are laid over the shim.
  • the beams from fig 9 can be seen, as well as the filling components (fig 11).
  • the conventional flashing 33 is located at the bottom edge of the roof slope.
  • a top sill 37 which interlocks to the top end of the side walls 22 and may be secured thereto by screws into the screw groove made on the extrusion 64 of figure 9.
  • This sill 37 discloses on each side a ridge enabling the setting of electrical lines which may be connected to the hollow channels 70 (fig 6, detailed below), and installed horizontally.
  • this sill 37 is used as an anchor for a stay 29, shown in figure 3, during concrete pouring to reinforce the upright side wall 22.
  • This stay consists of an upright steel extrusion, abutting against the interior side of the building upright wall 22 and anchored at its top end to the wall 22 in the upper sill 37.
  • An inclined adjustment stem 29 (fig 3) is anchored to the flooring at a distance of approximately 1 to 2 meters from the base of the wall 22, and a square is provided to support the wooden beams (and thus make a scaffolding so that the workers may pour the concrete into the walls). These stays must be installed at approximately two meters intervals, and are recovered after completion of the building construction for other projects.
  • the roofing 24 is inclined, with the lateral walls 22 having different lengths so as to support this sloped roof.
  • the lateral walls 22 of the building are therefore made as a ladder, i.e. in steps.
  • the top of the wall supporting these beams will be straight and will increase in height by 20 centimetres increments at each meter.
  • lateral walls 22 No sectioning will therefore be required on the building site, and the extrusions of the lateral walls 22 will be of a different length but these types of lengths will be limited.
  • the top of these lateral walls 22 being made in steps, they will receive the upper sill 37 onto which a triangular panel 38 will be mounted to fill the gap between the building side wall 22 and the sloped roof 24.
  • This triangular panel 38 may be made from full or empty wood, of a frame with an integral mosquito net to afford good air circulation, of a frame with permanent glass, or with ventilation louvres, according to the tastes of the customer.
  • ferro-concrete beams will be connected to the wall by reinforced steel rods included into the ferro-concrete of the walls and of the rafters 34.
  • the roof 24 will be connected to the rafters 34 by reinforcing steel rods cast into the rafter 34 and filled at the same time in the concrete cells 42 of the roof 24.
  • wooden beams are alternately used instead of the concrete beams, the latter are bolted with threaded stems cast on the concrete walls and extending through the beams.
  • the PVC extrusion constituting the roof will be anchored to the wooden beams by screws or by galvanized nails.
  • FIGS 6 and 7 show in horizontal cross-section and in isometric view some of the side walls 22 of the house 20.
  • the side wall 22 is hollow, consisting of a plurality of hollow panel assemblies 40, 40, ... being interlocked to one another in successive pairs in a fashion detailed below.
  • Each panel assembly 40 is rectangular, and preferably square, in cross-section, defining four side walls circumscribing a closed inner cell 42.
  • the top end of the panel assemblies 40 forms an open mouth, adapted to receive flow-through concrete to be poured inside the panel assembly inner cell 42.
  • the side walls of the panel assemblies 40 should be made from a waterproof, rigid material, being relatively thin while being capable of withstanding the loading of concrete inside the inner cell 42.
  • This panel assembly side wall is made of an extruded thermoplastic sheet material.
  • Figures 8-13 show the various extruded thermoplastic sheet components making the various panel members forming the cross-sectionally quadrangular panel assemblies 40 of the house.
  • Figure 8 is particular suggests how the extrusion in their disassembled condition can be stacked to take the minimum volume, so as to reduce shipping costs. All the components have been thought off to enable the most efficient stacking features. The extrusions will be shipped in boxes into which may be loaded the various required structural components to make a given wall or roof area.
  • the extrusion components 64 shown in figure 9 will be applied flatly against the rafters forming the roof frame 24. Once these extrusions 64 are anchored to the roof frame, additional extrusions will be mounted by sliding same from the top down of the building. The periphery of the roof will be closed by the flashing strips 33. These extrusions will keep the concrete in place during pouring thereof, and will ensure the presence of a peripheral flashing 33, around the roofing 24, and of a water outlet. Once all the roofing extrusions have been mounted and anchored, they are filled, one side at a time, at the front or at the rear, with regular concrete or with concrete containing polystyrene pellets.
  • polystyrene pellets will decrease the overall weight of the concrete, and thus the load supported by the extrusions, and will increase the thermal insulation ratio of the roof 24.
  • the rear part may be filled with concrete to thus complete the building.
  • the building 20 will then become completely monolithic, and all the components will become anchored to one another as if they would have been cast all at the same time.
  • the reinforcing steel anchoring will also be provided between the concrete flooring 26 and the walls 22.
  • a cross-sectionally C-shape panel member 70 may also be provided, having a pair of inturned flanges 72a, 72b, at opposite end edges thereof, for through passage by electrical lines (not shown).
  • electrical lines for accessing the electrical lines inside channel 70, there is only required to bore a hollow channel in the wall 44, to allow the electrical lines to extend to the top of the wall 22, and to jump from one room to another through the gap provided in the upper sill 37.
  • the V-shape component 64 in figure 9 constitutes the main portion of the present construction system.
  • the component 52 in figure 10 is a connector element which enables to obtain the T intersections with the walls 22.
  • the component 44 is used with component 64 of figure 9 to constitute one of the exterior faces of the walls 22.
  • the component 70 is an extrusion with interlocks with the ears 46c, 46d, of component 44 of fig 10 inside the wall 22, so as to provide vertical channels for the eventual passage of electrical conduits.
  • the component 60 is an extrusion which is used to make the corners of the building 20.
  • each cross-sectionally quadrangular panel assembly 40 includes two L-shape panel components 64, 64', which make three of the four walls of the panel assembly 40 (one of the four legs thereof extending to a second adjacent panel assembly), and a flat panel component 44 interconnecting the two L-panel components 64, 64'.
  • end ears 46a, 46f, of flat panel component 44 hookingly engage transversely into the free end channel pockets 68, 68, of the two L-panel components 64, 64', thus spacedly interlocking in parallel relationship the two corresponding legs of these panel components 64, 64'; while the ear 66a of one L-panel component 64 hookingly engages with the ear 66b of the adjacent L-panel component 64'; hence forming a stable cross-sectionally quadrangular hollow panel assembly 40.
  • An important advantage of such interconnection system for the panel components of a given pair of panel assemblies 40, 40 is the sliding adjustability of the ears 46a, 46f, lengthwisely of the channels formed by the L-panel pockets 68, 68.
  • This relative sliding ability of the two L-panels 64, 64 enable unskilled workers to successively install these L-panels side by side, progressively, with minimal danger of accidental structural damage while providing continuous axial sliding adjustment capability therebetween.
  • Such a construction system will therefore provide real cost savings with respect to the in situ labour force, thanks to foolproof panel assembly design.
  • the L-shape corner panel component 60 is used, for two of the four sides of the panel assembly 40.
  • a flat panel component 52 is attached by its axial ear 54b to the ear 62b of L-panel 60.
  • the last side of the quadrangular panel assembly 40 is formed by one leg of the L-shape component 64", with ear 66c thereof hooking with axial ear 54e of flat panel 52, and with ear 62a of L-panel 60 hooking with elbowed part ear 66a of L-panel component 64".
  • Figures 14 and 15 show door and window assemblies made with plastic extrusions.
  • the windows 74 are mounted into the side wall 22 about a false frame 76 consisting of an extrusion.
  • This extrusion 76 is used to support the windows 74 but also discloses a peripheral groove which may be used to hook shielding weather-boards to the false frame 76.
  • the window frame 76 is installed at the same time as the wall extrusions 22. However, the window sill is installed only after concrete has set.
  • the door 84 is hingedly mounted to a door frame 80, which is made from PVC and is connected to the wall extrusions 22 by a specific connector component 82 made also from plastic.
  • the door frame installation is done in a similar fashion as that of the window frame installation, except that in figure 14, the connector extrusion 82 is used for anchoring the door frame 80 to the PVC frame.
  • the window sill must be installed, and the window 74 itself must thereafter be mounted into the false frame 76.
  • the door frame 80 may be mounted at the same time as the extrusions and be in position during concrete pouring.
  • the completed building thus consists of concrete walls covered with plastic, which may be left white or dyed (either deep-dyed or painted with a special paint).
  • the edges of the windows and the soffits can however be of a different colour.
  • the inside of the building thus consists of a white plastic surface for the walls and for the roofs, with the exposed rafters of varnished wood or cast concrete rafters in position inside a coloured fibreglass casing.
  • the plastic used can be from PVC or other thermosetting plastic material.
  • the plastics used are freely available on the market and are currently manufactured by known corporations.
  • the coextrusion system which will be used is a well known system in the industry, and by adding mineral fibres or filling materials thereto, resistance of plastic should be improved.
  • All the building system has been developed so that, during the preparation of the plans of the building, all the components forming the building be defined by computed-assisted design, to be thereafter manufactured and precut in the home factory. No component sectioning is required on the building site, and the system assembly is performed by unskilled labour. This system thus enables the conception and production at a large scale of the building, while considerably decreasing the timeframe for manufacture and execution thereof.
