Abstract

Insulated wall forms that remain in place and include an exterior wall covering such as stucco or a brick faccedil;ade, an interior wall covering such as gypsum board or both an exterior wall covering and an interior wall covering greatly simplify wall construction using a hardenable material such as concrete and reduce steps needed to put a finished wall in place.

Description

ISOLATED WALL STRUCTURE This invention relates in general to a component and a system used to construct walls of permanent hardenable material in a building construction. This invention relates in particular to a component and a system that remains in place after a hardenable material, such as concrete, hardened to form the walls hardens. This invention relates more particularly to a component and a system in which at least one, and preferably both, of the inner and outer surfaces of the wall, constitute a portion of the component. In the United States, the manufacture of concrete walls typically involves several steps. First, the walls of the form that establish a cavity or space are constructed. Second, concrete is poured into the cavity or space. Third, the concrete is allowed to cure or cure enough to allow the removal of the walls of the form. Fourth, the walls of the form are removed. In residential construction, the concrete foundation wall and other concrete wall fabrication employ the above procedure. After completing the fabrication of the concrete wall, the required wooden frame is built on top of the concrete walls, in addition to concrete concrete slabs, or both. A typical next step involves inserting insulation between the members of wooden frames. After that, he The wall ends both inside and outside. Previous practices are time consuming, inefficient, costly and wasteful, particularly in terms of materials and labor used to manufacture and then remove the walls of the form. As dictated by common building practices, especially in colder climates, all walls, including the foundation walls, must be isolated, so the need to remove the walls of the form and then build and isolate the walls of the wooden frame, retards the following steps of construction of the building. An alternative procedure, practiced for several years, particularly in Europe, combines several of the construction steps using a foam insulation material to permanently manufacture walls. Because the foam insulation material remains in place, no additional insulation is necessary and the finishing materials can be applied to the interior and exterior walls, as desired. : This procedure works both for the foundation walls and for the walls that rise above the floor. U.S. Patent No. 5,657,600 discloses a building component comprising first and second high density foam panels arranged in a parallel and spaced relation to each other. At least two bridge members extend into the space between the panels, and connect the panels together by being molded into the panels.

Each bridge member has a pair of elongated end plates, oriented vertically and which meet against their outer surfaces of the foam panels. The bridge member can adopt an X-shape and be made of a plastic material, such as high density foam retardant polyethylene, polypropylene foam retarder or polystyrene. USP 4,730,422 describes a structure. formador d.e concrete wall, insulating type, non-separable, a device and a system to join wall coverings. In modular structures of form for concrete, of foamed synthetic plastic, numerous pairs of modular and permeable forming panels are stacked, for concrete, modular, one on top of the other, and are connected end to end. Pairs of panels include. vertically spaced rows of T-shaped tie slots, within which sliding T-shaped ends of synthetic plastic ties are slidably fitted. The outer surfaces of the slot sections have enhanced mooring locator indicators, which allow insulators to be screwed through the panel, into the synthetic plastic ties, to securely anchor the finishing coverings for the exterior wall, to the panels or wall sections. USP 4,889.31 0 describes an improved concrete forming system, comprising a series of first and second opposed polystyrene foam panels, connected in spaced, opposite, parallel relationship. The foam panels have mooring slots vertically aligned, defined along their upper and lower edges. The plastic moorings fit within the mooring slots to hold the foam panels in their spaced configuration. Each mooring end has internal and external spaced vane members, T-shaped, which respectively fit against the inner and outer surfaces. external panel Tie ends may break after the concrete hardens if one wishes to remove any of the foam panels, or both. The ties can be modular in that they comprise tie-down ends and a spacing strip that can be lengthened or shortened, as desired, to vary the spacing between the foam panels. U.S. 4, 936,540 discloses fasteners to mutually secure a pair of spaced-apart panels, such as foam panels. The moorings have at least one bevelled end that allows them to be forced through the foam panels without first cutting a mooring slot. The ties may also have an end plate, integrally formed, opposite the beveled end. Once the bevelled end passes through both spaced foam panels, a spacer can be inserted between the panels to maintain proper alignment and a fitting bevel fitted over the bevelled end to hold the panels in place. USP 5, 107,648 describes an insulated wall construction using foam boards with tongue and groove, maintained in a spaced configuration by spacing bar assemblies. Spacer bar assemblies comprise an external support plate with a bar receiving segment passing through the foam board; an internal paddle plate. which slides over the bar receiving segment, a spacer bar that fits within the bar receiving segments of both boards, and locking pins that hold one end of the space bar in place within each bar receiving segment. The spacer bar can take any of many configurations ranging from a cylindrical shape (both solid and hollow), through a condition formed (different from the indian ci), to threaded with external thread. "In this last configuration the plates provide a base for the covering material, such as a gypsum and stucco board The present invention is an isolated wall shape comprising a first panel segment, a second panel segment and a plurality of connectors; The first panel segment and the second panel segment are generally planar structures, the first and second panel segments being spaced from one another in order to form a cavity, and being oriented in such a way that the first panel segment is generally parallel to the second panel segment, each of the connectors having a first end and a second end that is remote from the first end; probably the first end to the first panel segment, and the second end being detachably attached to the second panel segment; maintaining the plurality of connectors the segments of. first and second panel in a spaced orientation, generally parallel; defining the wall shape, a cavity adapted to receive a hardenable filling material.

BRIEF DESCRIPTION OF THE DIAMETERS Figure (Fig. 1) is a fragmentary top plan view of a portion of a modality of a panel segment. Figure 2 is a fragmentary top plan view, of the embodiment shown in Figure 1, together with a portion of a cone-cone. Figure 3 is a horizontal sectional view of an isolated wall shape including two opposing panel segments, of the type shown in Figure 1, and a plurality of connectors. Figure 4 is a fragmentary top plan view of a portion of an alternative and preferred embodiment of a panel segment. . Figure 1 illustrates a portion of a wall panel segment 20, suitable for use as part of the wall shape 10 (shown in Figure 3). The segment of panel 20 is. a laminar structure including the inner layer 21 and the outer layer. 25. The inner layer 21 has an inner surface 22 and an outer surface 23, generally parallel, spaced apart. The inner layer 21 also has therein defined a plurality of passages 24 which intersect and are in fluid communication with both the inner surface 22 and with the outer surface 23. The outer layer 25 has an internal surface 26 and an outer surface 28 generally parallel, spaced apart. The outer layer 25 also has a plurality of slots 27 defined therein. The outer surface 23 of the inner layer 21 and the inner surface 26 of the outer layer 25 are in operative contact with each other. Said operative contact conveniently occurs by means of an adhesive material (not shown), disposed between the surfaces 23 and 26. The slots 27, preferably T-shaped, are in fluid communication with the passages 24 of the inner layer 21. A combination of slots 27 and passages 24 constitutes a plurality of channels that are adapted to receive connecting ends (shown in Figures 2 and 3). The channels in the wall panel segment 20, also referred to as the first panel segment, preferably comprise an elongated opening in the inner layer 21, preferably a foam layer, and a cavity in the outer layer 25. The opening and the cavity are in fluid communication with each other. Each of the cavity and the opening has a width. The width of the cavity preferably is greater than the width of the opening. These channels easily receive connectors, such as the connectors 30 shown in Figure 2. Figure 2 illustrates a fragmentary section of the wall panel segment 20, together with a fragmentary section of a connector 30. The connector 30 has a first end 31 and, spaced by means of a central arrow 33, a second end 35 (shown in figure 3). An intermediate portion of the arrow 33, close to, but spaced from, each of the ends 31 and 35, is externally threaded. Figure 2 shows the threaded segment 32 close to the end 31. The threaded segment 34 (not shown) is close to, but spaced from, the end 35 (shown only in Figure 3). The internally threaded compression fittings 36 are threadably coupled with the externally threaded arrow portions 32 and 34 (not shown) in order to hold the connector 30 in a fixed position with respect to the wall panel segments 20 and 40 (shown in Figure 3). Although not shown in Figures 2 and 3, the panel segments. 20 and 40 preferably additionally comprise a sealing means which is disposed between a connecting end, such as the first end 31 of the connector 30, and its associated compression fitting or nut 36, such that the sealing means is in operative contact or sealant with both the inner foam layer 21 of the panel segment 20, or the inner foam layer 41 of the panel segment 40, whichever is appropriate, as well as with the compression nut 36.

Those skilled in the art will recognize that a variety of substitutes can serve the same purpose as the combination of externally threaded shaft segments 32 and 34 and internally threaded compression attachments 36. By way of example only, and without limitation, said substitutes include one or more projections from the arrow, on which a collar slides, then twists and locks; or a series of rings on the arrow on which a collar with internally defined ridges or internally defined locking means slides, and then is left in that position. Those who are experts in the field will also recognize that the attachments of • compression 36, and any of the alternatives, will not necessarily be solid or continuous forms. In fact, in order to facilitate installation, the attachments preferably have a slot that communicates between an outer edge of the attachment and a central opening of the attachment., such as an internally threaded portion of the attachments 36. The slot allows the attachment to slide over the central arrow 33 of the connector 30, at a field or assembly site. Figure 3 illustrates the shape of wall 10. The shape 10 comprises a wall segment 20, the wall panel segment 40 and a plurality of linked connectors 30. The wall panel segment 40 can be, and preferably is, a symmetrically opposite image of the wall segment 20, except for the material. from which the outer layers 25 and 45 are manufactured.

Accordingly, the wall panel segment 40 is a laminar structure that includes the inner layer 41 and the outer layer 45. The inner layer 41 has an inner surface 42 and an outer surface 43 generally parallel, spaced apart. The inner layer 41 has an inner surface 42 and an outer surface 43, generally parallel, spaced apart. The inner layer 41 also has therein defined a plurality of intersecting passages 44, and are in fluid communication with both the inner surface 42 and the outer surface 43. The outer layer 45 has an inner surface 46 and an outer surface 48 spaced, usually parallel. The outer layer 45 has an inner surface 46 and an outer surface 48 generally parallel, spaced apart. The outer layer 45 also has a plurality of slots 47 defined therein. The outer surface 43 of the inner layer 41 and the inner surface 46 of the outer layer 45 are in operative contact with each other. Said operative contact conveniently occurs by means of an adhesive material (not shown), disposed between the surfaces 43 and 46. The slots 47, preferably T-shaped, are in fluid communication with the passages 44 of the inner layer 41. Like the combination of slots 27 and passages 24 shown in Figure 1, a combination of slots 47 and passages 44 produces a plurality of channels that are adapted to receive connector ends (shown in Figures 2 and 3). The channels in segment 40 of the wall panel, also referred to as a panel segment, they preferably comprise an elongated opening in the inner layer 41, preferably a foam layer and a cavity in the eternal layer 45. As with their counterparts in the layers 21 and 25, the opening y. the cavity is in fluid communication with each other, and each has a width, the width of the cavity being preferably greater than that of the aperture. Preferably the channels are adapted to receive connecting ends, such as those of the connectors 30 shown in Figures 2 and 3. The connectors, such as the connectors 30, are preferably arranged in numerous connector assemblies. Each connector assembly more preferably comprises a network in which each connector is oriented so as to be spaced apart from, and generally parallel to, at least one other connector. The orientation is conveniently maintained by means of at least one connector clamp between each of two adjacent connectors, within a connector assembly. As shown in Figure 3, the plurality of connectors 30 are interconnected or interconnected by means of a plurality of links 32. Figure 3 shows two links 32 between each pair of connectors 30. Although two ties 32 per. Pair of connectors 30 produce very results. satisfactory in terms of. Simplicity and uniformity of spacing, can be used. a greater or lesser number of moorings, without going beyond the scope or spirit of the invention. In fact, it is possible to eliminate moorings altogether, if you want The ties 32 may be flexible to accommodate storage and handling prior to use as part of the wall shape 10. The links 32 may also be rigid to provide additional stability, before disposing a hardenable material within the cavity formed by the internal surfaces 22 (FIG. 1) and 42 of the corresponding panel segments 20 and 40. The ends 31 and 35 of the connectors 30 can take any of a variety of forms, without departing from the 10 spirit and scope of the present invention. The shape simply needs to accommodate a slidable coupling with at least a portion of slots 27 (FIG. 2) and 47 of the corresponding panel segments 20 and 40. The shape conveniently provides • frictional but slidable coupling with the surfaces of the 15 slots 27 and 47. Forms include, for example, squares, rectangles, parallelograms, trapezoids, polygons (for example, hexagons and octagons), circles and ellipses. Although the shapes preferably have a thickness that is at least equal to the width of the slots 27 and 47, they more preferably have a 20 thickness that slightly exceeds the width, in order to provide a good frictional adjustment. A particularly preferred connector is a collapsible connector, such as that described in the model patent 383,373 and in USP 4,706,429, USP 4,730,422 and in USP 4,885,888. The 25 relevant teachings of the four patents are incorporated here by means of this reference. By using such connectors, the insulated wall shape of the present invention can be assembled and then crushed or folded around the connectors, to a flat configuration, for shipping or transport. When it is ready for use on the job site, it can simply be deployed around the connectors, and can be deployed on the site. Figure 4 shows a preferred alternative embodiment of a panel segment designated by the reference number 20 '. The segment 20 'differs from the panel segment 20 in that the outer layer 25' has no grooves defined therein, while the outer layer 25 has grooves 27 defined therein. As well as the segment 20, the segment 20 'is a laminar structure that includes the inner layer 21' and the outer layer 25 '. The inner layer 21' has an inner surface 22 'and an outer surface 23' generally parallel, spaced. The inner layer 21 'also has defined therein a plurality of passages 24' which intersect and are in fluid communication with both the inner surface 22 'and the outer surface 23'. The 24 'passages are preferably T-shaped, similar to that provided by a combination of the passages 24 and the slots 27 of the panel 20. While Figure 4 shows the located passages 24' close to, or intersecting the surface external, 23 'of the inner layer 21, the passage can also be displaced towards the inner surface 22', so that: a) it is located totally within the inner layer 21"; b) intersect only the internal surface 22 '; and c) is in fluid communication only with the inner surface 22 '. The outer layer 25 'has an inner surface 25' and an external surface 28 'generally parallel, spaced apart. The outer surface 23 'of the inner layer 21' and the inner surface 26 'of the outer layer 25' are in mutual operative contact. As with the panel 20, said operative contact occurs conveniently by means of an adhesive material (not shown), disposed between the surfaces 23 'and 26'. The T-shaped passages 27 and 24 'can be manufactured by means of any suitable file. For example, a cutter or other similar device may be used to cut the passages, after placing the inner layer 21 'and the outer layer 25' in mutual operative contact. . A more preferred technique uses narrow strips (in relation to the outer layer 25 ') of the inner layer 21'. The outer surface 23 'of the inner layer 21' has a longitudinal or masonry step defined thereon on each side, so that when two strips of the inner layer 21 'are placed close to each other, but not in mutual physical contact , define a T-shaped passage 24 '. The outer panel 40 can be modified, and preferably it is, in the same way as the panel 20, to produce an external panel 40' (not shown). Similarly, an alternate and preferred wall shape 10 'includes internal panels 20' and external panels 40 'instead of internal panels 20 and external panels 40.

Of course, the panels can be mixed and coupled in such a way as to provide, for example, an internal panel 20 and an external panel 40 ', two internal panels 20, 20' or a combination of a panel 20 and a panel 20-, or two external panels 40, 40 '; or a combination of a panel 40 and a panel 40 ', depending on factors such as the selection of the wall and the location of the wall. The internal panels 20 and 20 'are laminar structures comprising at least two layers: an inner layer comprising an insulating foam material, and an outer layer comprising an inner surface material. Inner surface material is selected from gypsum boards, compressed fiber boards, wood, plywood, brick, fiber reinforced boards, vinyl boards or any other material that provides aesthetic performance, functional performance or both, acceptable. The outer panels 40 and 40 'are laminar structures comprising at least two layers, an inner layer comprising an insulating foam material and an outer layer comprising an outer surface material. The exterior surface material is selected from: wood, brick, stucco, concrete block, cement board laminate, fiber reinforced board, lining board, wood laminate, brick veneer or any other material that provides acceptable functional performance • and, conveniently, also aesthetic appeal.

The insulating foam material may be any cellular insulating material that is sufficiently rigid to substantially maintain its shape during construction and use of the wall form. Preferably the insulating foam panel is a cellular polymeric foam. It can be made of a thermoplastic or thermoplastic polymer. Suitable polymers include: polyethylene (including low density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HPE) and substantially linear ethylene interpolymers), polypropylene, polyurethane, polyisocyanurate, copoiimers of ethylene-vinyl acetate, polyvinyl chloride, phenol-formaldehyde resins, ethylene-styrene and polymer interpolymers and alkenyl-aromatic copolymers, including derivatives of alkenyl aromatic compounds, such as styrene, alpha-methylstyrene, ethylstyrene, Nylbenzene, vinyltoluene, chlorostyrene and bromostyrene. The preferred alkenyl aromatic polymer is polystyrene. Minor amounts of monoethylenically unsaturated compounds can be copolymerized, such as acids and alkyl esters of 2 to 6 carbon atoms, ionomeric derivatives and dienes of 4 to 6 carbon atoms, with alkenyl aromatic compounds. Examples of copolymerizable compounds include: acrylic acid, methacrylic acid, ethacrylic acid, maleic acid, itaconic acid and acrylonitrile. , Mixtures of any two or more of the foregoing, or mixtures of any of the foregoing with another polymer or mixtures thereof, are suitable. resin. Rigid foams of polyurethane, polystyrene, polyisocyanurate and phenolic foams are preferred; polystyrene and polyisocyanurate foams being especially preferred. The foams can be used as is, or they can have a mechanically modified external surface. Mechanical modification includes operations such as sanding, scraping, flattening or other action that alters the external surface of its state as it was formed. Suitable alkenyl aromatic polymers include derivatives of alkenyl aromatic compounds, such as styrene, alpha-methylstyrene, ethylstyrene, vinylbenzene, vinyltoluene, chlorostearate and bromostyrene. A preferred alkenyl aromatic polymer is polystyrene. Minor amounts of monoethylenically unsaturated compounds, such as alkyl acids and esters of 2 to 6 carbon atoms, ionomeric derivatives and dimers of 4 to 6 carbon atoms, can be copolymerized with the alkenyl aromatics. Examples of copolymerizable compounds include: acrylic acid, methacrylic acid, ethacrylic acid, maleic acid, itaconic acid, acrylonitrile, maleic anhydride, methyl acrylate, ethyl acrylate, isobutyl acrylate, n-butyl acrylate, methyl methacrylate, acetate of vinyl and butadiene. Preferred foams consist substantially (i.e., more than 95 percent) and preferably entirely of polystyrene. Any conventional process can prepare the insulating foam materials, extrusion with foaming being preferred. In order to facilitate the manufacture of the wall shapes 10 and 1 0 ', as well as to decrease the time for their assembly, a lubricant material can be arranged on the surfaces of the connecting ends 31 and 35, which will come into contact with the slots 27. and 47 of the wall panel segments 20 and 40 or the slots 24 'and 44' (not shown) of the segments 20 'and 40' of the wall panel. Suitable lubricating materials include mineral oils, synthetic oils and fluorocarbons. The wall shapes 10 and 10 'define a cavity designed to accommodate and shape a load carrier material, preferably a hardenable material, such as concrete, "reinforced concrete with fiber or reinforced concrete with fillers. The cavity may additionally comprise a liner for the cavity., the liner for the cavity is adjacent to, and in physical contact with, at least a surface portion of the internal surfaces of the selected combination of internal and external panels 20, 20 ', 40 and 40'. The internal and external surfaces, respectively, are 22, 22 ', 42 and 42' (not shown). The liner for the cavity comprises a film made of a thermoplastic polymer, which is a polyolefin, such as polypropylene, low density polyethylene, high density polyethylene or linear low density polyethylene.; a polyamide, an aromatic polymer of alkenyl, such as polystyrene ,. a poly (chloride of vinyl), a polycarbonate, an acrylic polymer or a ppliester. The film may not be oriented, single-oriented, or biaxially oriented. The film may contain one or more conventional additives, such as fillers, pigments, dyes, antioxidants, stabilizers for ultraviolet light, fire retardant materials (recognizing that all organic materials will be burned under the right conditions) and processing aids. Any load carrying material that provides adequate strength and rigidity can be used. In simpler or less expensive wall constructions, the load carrier material may be, for example, wood, stone, earth,. sand, metal. These are advantageously used in the form of particles, so that they can be easily poured into the shape assembly, as a bulk filling. However, this invention is particularly adapted for use with a charge carrier material that is poured into the site after the system of wall panels, insulating foam panels and panel connectors is assembled, and then hardens. Consequently, any of the many forms of cement, such as Portland cement, aluminous cement and hydraulic cements, are suitable, as are hardenable clays, such as adobe, mortar and hardenable mixtures of clays and cement. It is generally preferred, for reasons of cost and property, to use concrete, which is an aggregate of a material such as gravel, sand, sand, broken stone, slag or ash, in a hardenable matrix, usually mortar, or in the form of cement, such as Portland cement, aluminous cement or hydraulic cement. Generally, any concrete or aggregate that is useful for preparing load-bearing building walls is suitable for use with the present invention.
