Definitions
- This invention relates an improved, strong, non-polystyrene insulating concrete form building system which is comprised of a simplified form geometry with smooth, non-articulated ends and side walls, self-aligning ribs and grooves for locking courses of the forms together, a web fastening clip internal to the insulating concrete form which holds the end webs of adjacent insulating concrete forms tightly together, thereby working in tandem with the aforementioned self-aligning ribs and a system of internal reinforcement bar holders which ensures the precise positioning of single or multiple reinforcement bars both in both the horizontal and vertical planes of the wall.
- the non-polystyrene insulating concrete form has been in use as a building component for several decades, most notably in Europe in the western hemisphere. While the technology of wood-cement or wood-concrete products, as they are generically called, was already underway in Europe during the 1930's, the real impetus for such a building system in the western hemisphere can be traced to the widespread destruction of buildings that resulted from World War II. The European reconstruction period began with much rubble (including many partially destroyed building timbers) and a short supply of Portland cement.
- the wood concrete forms In comparison to polystyrene insulating concrete forms in current use in North America, the wood concrete forms have several advantages.
- the fabrication of the wood concrete forms is not a petroleum-based in their manufacturing process. Instead, the process uses a high percentage of recycled materials from post-industrial wood source that would otherwise end up in the earth's landfills.
- the manufacturing process for the wood concrete forms also uses organic, non-toxic materials.
- the wood concrete is highly flame- and smoke-resistant when subjected to the heat of flame and it will not give off toxic vapors or fumes as will polystyrene when it is melts in the presence of flame. Termites will not eat the wood concrete forms nor will other wood-eating vermin.
- wood concrete wall system is hygroscopic, that is, the wall system “breathes”, taking on and giving off water vapor as it seeks ambient humidity levels. This breathing characteristic of the wood concrete form prevents the accumulation of excessive moisture in the wall thereby preventing growth of molds and mildews that have been known to occur in other non-breathing wall systems.

Abstract
A simplified insulating concrete form building system comprised of forms made from wood chips or other organic fibers, embedded in a Portland cement matrix, molded and trimmed into various shapes and sizes. The forms are held in position within the wall by means of unique, simplified form geometry and an internal fastening clip which combine to improve alignment and stability of the wall prior to filling the forms with concrete. The simplified geometry reduces worker error in orienting the form correctly within the wall thereby reducing handling and corresponding fatigue. The form's smooth faces provide more compact palletized shipments of forms, thereby reducing cost and damage in shipment. Concrete reinforcement bars are held within forms using a system of reinforcement bar holders which enables the precise positioning of the reinforcement within the wall, thereby increasing speed and accuracy of construction as well as structural performance of the wall assembly.
Description
- This application contains subject matter which is related to the subject matter of the following co-pending application. Each of the below listed applications is hereby incorporated herein by reference in its entirety:
- The present application is a continuation-in-part of an application entitled “SIMPLIFIED NON-POLYSTYRENE PERMANENT INSULATING CONCRETE FORM BUILDING SYSTEM”, Inventor Michael Edward Nylin, filed Sep. 18, 2007, Ser. No. 11/901,517; which is a non-provisional application that claims the benefit of provisional patent application entitled “A SIMPLIFIED NON-POLYSTYRENE PERMANENT INSULTING CONCRETE FORM BUILDING SYSTEM”, Inventor Michael Edward Nylin, filed Sep. 19, 2006, Ser. No. 60/845,607.
- This invention relates an improved, strong, non-polystyrene insulating concrete form building system which is comprised of a simplified form geometry with smooth, non-articulated ends and side walls, self-aligning ribs and grooves for locking courses of the forms together, a web fastening clip internal to the insulating concrete form which holds the end webs of adjacent insulating concrete forms tightly together, thereby working in tandem with the aforementioned self-aligning ribs and a system of internal reinforcement bar holders which ensures the precise positioning of single or multiple reinforcement bars both in both the horizontal and vertical planes of the wall.
- The non-polystyrene insulating concrete form has been in use as a building component for several decades, most notably in Europe in the western hemisphere. While the technology of wood-cement or wood-concrete products, as they are generically called, was already underway in Europe during the 1930's, the real impetus for such a building system in the western hemisphere can be traced to the widespread destruction of buildings that resulted from World War II. The European reconstruction period began with much rubble (including many partially destroyed building timbers) and a short supply of Portland cement. Necessity often being the mother of invention, the Germans and Austrians pioneered a way to recycle much of the destroyed timbers into chips of wood, treating the wood chips to isolate the organic sugar compounds in them to prevent these compounds from leaching out of the wood chips and interfering with the chemical reaction known as hydration process that takes place when Portland cement is mixed with water. These coated chips would then be mixed with Portland cement and water to create a fictile, moldable matrix. The forms molded of this matrix are used to create wall assemblies by dry-stacking the forms (i.e. using no mortar between the forms), inserting reinforcement bars within the internal voids of the forms and then filling the forms with concrete. The forms stay permanently in place, thereby becoming part of the wall assembly and provide excellent fire, mold, and termite resistance. These forms also have excellent thermal insulation and sound attenuation characteristics.
- In comparison to polystyrene insulating concrete forms in current use in North America, the wood concrete forms have several advantages. The fabrication of the wood concrete forms is not a petroleum-based in their manufacturing process. Instead, the process uses a high percentage of recycled materials from post-industrial wood source that would otherwise end up in the earth's landfills. The manufacturing process for the wood concrete forms also uses organic, non-toxic materials. The wood concrete is highly flame- and smoke-resistant when subjected to the heat of flame and it will not give off toxic vapors or fumes as will polystyrene when it is melts in the presence of flame. Termites will not eat the wood concrete forms nor will other wood-eating vermin. Unlike the case with polystyrene forms, fasteners such as nails or screws may be attached anywhere on the form with excellent holding power. Another advantage over polystyrene is that stuccos, plasters and other finishes may be directly applied to the wood-concrete forms without additional sub-surface preparation. Furthermore, the wood concrete wall system is hygroscopic, that is, the wall system “breathes”, taking on and giving off water vapor as it seeks ambient humidity levels. This breathing characteristic of the wood concrete form prevents the accumulation of excessive moisture in the wall thereby preventing growth of molds and mildews that have been known to occur in other non-breathing wall systems. The incursion of molds and mildews has been on the rise in new construction using traditional “stick-built” construction methodologies cases especially when the stick-built construction is too tightly sealed with building wraps and/or sealants. The stick-built approach will often trap moisture within walls, creating a favorable environment for mold and mildew growth. These molds are suspected to be one of the lead causes in the growing number of asthma and other respiratory ailments experienced in recent years, especially amongst children.
- While the wood-concrete insulating form technology was primarily pioneered within the western hemisphere on the European continent, there have been a small number of manufacturers in North America, though their products have not, until recently, attracted much interest in the North American construction industry. One of the primary reasons for wood concrete's failure to gain widespread market acceptance in North America has been the entrenched mindset of the North American construction industry. That mindset has been one which is predominated by the plywood and dimension lumber based construction processes.
- For the time when virgin forests of “old wood” were plentiful in North America, stick-built construction remained economical in the short term. In more recent times however, there has been a growing awareness and understanding of the negative environmental implications attendant to the denuding of the earth's forests. This awareness has fostered interest in alternative methodologies of construction which are more environmentally responsible over the longer term. Such new interest is evident in the increasing commitment levels to “green” or environmentally sustainable architecture and construction methods in both the public and private sectors. With its characteristically high recycled material content, its excellent thermal and sound insulating properties, its hygroscopic nature, ease of construction and the durable, strong structure it produces, it appears the time for the non-polystyrene insulating concrete form in North America may have arrived.
- As already noted, the majority of development of the wood concrete technology has occurred in the western hemisphere on the European continent. Within the wood concrete insulating concrete form manufacturing community, the most common product designs produced by the most prominent European manufacturers (e.g., DURISOL, THERMOSPAN, ISOSPAN, BRISOLIT, etc.) come in a variety of geometric sizes and shapes with optional insulation inserts available to increase the form's thermal and sound insulation properties beyond that of the basic form.
- Virtually all of these wood-concrete forms include some type of articulated “male-female” end configurations. The reason for these male-female end configurations is an attempt by the manufacturer to facilitate a planar alignment of the forms during the process of assembling a wall. Another purpose of the male-female end shape is to interlock the wall forms so that relative movement between forms is resisted during the placement of reinforcing steel and, subsequently, the concrete within the forms. While this type of end configuration may provide a limited degree of interlocking of forms on a particular course within the wall, it does little or nothing at all to interlock successive courses in the wall together. As such, even with the interlocking end configuration, an accidental bumping of the wall by a construction worker or a piece of construction machinery can severely misalign the wall assembly prior to its being filled with reinforced concrete.
- Such use of asymmetrical, male-female ends on the forms creates two major disadvantages for wall assembly. First, care must be taken to orient the form properly in the wall with respect to adjacent forms so as to prevent improperly mating male-to-male or female-to-female end configurations. Such mistakes made by construction workers in this regard require additional handling by the worker to re-orient the form properly, thereby increasing worker fatigue. Secondly, at wall openings such as at doors and windows, the male-female end of the form located at the jamb (i.e., the side of the opening) of a door or window has to be smoothed by sawing, sanding or some other alternative course of action before window or door installation may proceed. This also can slow down the assembly of the wall.
- While the use of a male-female end configuration may offer some limited resistance to lateral movement which might occur in an accidental bumping of the wall during its construction or while waiting for the wall to be filled with concrete, the disadvantages of incomplete, multi-axis lateral stability in terms of bumping resistance, the possibility of mis-orientation of the form and the aforementioned required additional cutting or smoothing of the form at door and window jambs are serious drawbacks to an efficient construction process. Examples of these varying male-female end configurations may be found on the manufacturers' websites. Most notable European manufacturers for illustrating this male-female end configuration are DURISOL of Austria (www.durisol.at), THERMOSPAN of Austria (www.thermospan.at), ISOSPAN (www.isospan.eu) and BRISOLIT of Germany (www.brisolit.de).
- In addition, as illustrated by the K-X FASWALL system (www.faswall.com), the asymmetrical end configurations frequently require a special form for use at corners of buildings. As is the case with the FASWALL form, this can have a significant negative constraining impact on the overall design of the building and/or the ease of construction if the dimensions of the corner forms do not readily conform to the overall design module of the construction project. This violation of design modularity will frequently require additional cutting of forms at the construction site.
- Finally, in many building designs, especially those which employ structural engineers to calculate precise number and sizes of structural members, reinforcement bars, etc., the precise placement of the reinforcement bars within the concrete and the assurance of complete concrete cover surrounding the bars can be critical factors in the building's structural performance. Many manufacturers' non-polystyrene insulating concrete forms use a somewhat “hit-and-miss” approach with respect to the placement of the reinforcement bars. Accordingly, the precise location and/or orientation of the steel within the core and/or relative to other reinforcement bars within the form simply cannot often be assured.
- In view of the non-polystyrene insulating concrete forms currently available, a new insulating concrete form which does not require asymmetrical male/female end configurations for interlocking or alignment of the forms within the wall assembly nor any special corner forms and which actually increases the stability of the form within the wall assembly while providing for the ability to precisely position reinforcement bars within the form would be a significant improvement.

block 1002, at least two of a non-polystyrene insulatingconcrete form 100 are aligned, the non-polystyrene insulatingconcrete form 100 having a double middle webintegral slot 110. - In an exemplary embodiment of the present invention, non-polystyrene insulated
concrete forms 100 are assembled together to create wall assemblies by dry-stacking (i.e., no mortar between forms) successive courses of a non-polystyrene insulated concrete forms one upon another, usually with the longer longitudinal dimension of the a non-polystyrene insulated concrete forms in alignment with the plane of the wall. The non-polystyrene insulated concrete forms may be stacked in either running bond (i.e., vertical joints between non-polystyrene insulated concrete forms staggered to align with mid-point of forms immediately above and below it) or stack bond (vertical joints between non-polystyrene insulated concrete forms aligned in each successive course). - To begin a wall assembly, two non-polystyrene insulated concrete forms such as straight non-polystyrene insulated
concrete forms 100 are aligned end to end, aligning the non-polystyrene insulated concrete forms' horizontalbond beam cavities 109, as previously described. The method moves to block 1004. - In
block 1004, at least two of the non-polystyrene insulatingconcrete forms 100 are secured with at least one of afastening clip 200. In this regard, afastening clip 200 clamps together the abutted end webs of the adjacent non-polystyrene insulated concrete forms. Successive non-polystyrene insulated concrete forms in course can be placed in like manner until the entire course of forms is completed. The different configurations of non-polystyrene insulated concrete forms, which include the straight, the corner, the end-of-wall, and other non-polystyrene insulated concrete form assemble are fastened in the same manner. The method moves to block 1006. - In
block 1006, positioning at least one of a horizontalreinforcement bar holder 210 within certain of the double middle webintegral slot 110, the horizontalreinforcement bar holder 210 having asaddle 212 for retaining areinforcement bar 211. In this regard, once the first course's forms have been so aligned and interconnected with web fastening clips 200, the horizontalreinforcement bar holders 210 can be inserted at appropriate intervals along the length of the wall into the non-polystyrene insulated concrete forms' double middle webintegral slots 110, within the non-polystyrene insulated concrete forms' horizontalbond beam cavity 109. The method moves to block 1008. - In
block 1008, placing thereinforcement bar 211 into thesaddle 212. In this regard, with thehorizontal reinforcement holders 210 located in their corresponding double middle webintegral slots 110, thehorizontal reinforcement bar 211 may be snapped into the horizontal reinforcementbar holder saddle 212. The method moves to block 1010. - In
block 1010, positioning at least one of a horizontal-to-vertical (pair ofreinforcement bar holders 220 snapped together) reinforcement bar holder on thereinforcement bar 211, the horizontal-to-verticalreinforcement bar holder 220 having asecond saddle 222 for retaining asecond reinforcement bar reinforcement bar holder 220, as previously described. The method moves to block 1012. - In
block 1012, placing the second reinforcement bar into thesecond saddle 222. - Subsequent courses are assembled in a similar manner. As the non-polystyrene insulated concrete forms in succeeding courses are stacked upon the non-polystyrene insulated concrete forms immediately beneath them, the non-polystyrene insulated concrete forms' self-aligning
ribs 108 are seated in the corresponding self-aligninggrooves 107 of the forms in the course immediately below. These ribs and grooves facilitate vertical positioning and alignment of the non-polystyrene insulated concrete forms in the plane of the wall and interlock the non-polystyrene insulated concrete forms in the vertical plane of the wall, further strengthening the wall prior to filling the non-polystyrene insulated concrete forms with concrete. All courses of non-polystyrene insulated concrete forms are placed in accordance with this same procedure of clamping adjacent forms together with fastening clamps 200 and precisely positioning horizontal reinforcement bars 211 and vertical reinforcement bars 213 by snapping them into their respective horizontalreinforcement bar holders 210 and/or 220. The method moves to block 1014. - In
block 1014 non-polystyrene insulatedconcrete forms 100 are filled withconcrete 112. The method is exited. - An advantage of the present invention is that a single basic non-polystyrene insulated concrete form can be used to provide straight, corner, end-of-wall, half forms and lintel forms which simplifies modular building planning by eliminating special corner forms and using a single dimensional module.
- In addition, the smooth, non-articulated faces of the non-polystyrene insulated concrete form simplify the assembly of a wall by not requiring the construction worker to match male-female ends, thereby reducing assembly errors, unnecessary handling of and/or damage to the non-polystyrene insulated concrete forms and corresponding worker fatigue
- Furthermore, by virtue of its smooth faces, there are no projections on the non-polystyrene insulated concrete form to interfere with a tight palletizing of the non-polystyrene insulated
concrete forms 100 for shipment, thereby providing for a more compact shipment within the dimensional limits of the pallet. This results in less possibility of damage to the non-polystyrene insulatedconcrete forms 100 in loading, in transit and in unloading, thereby resulting in cost savings. - Another advantage of the present invention is that the
fastening clip 200 used to clamp adjacent wall forms together enhances wall stability and alignment of non-polystyrene insulated concrete forms in the horizontal plane of the wall during construction prior to the wall forms being filled with concrete. - In addition, the non-polystyrene insulated concrete form's self-aligning
ribs 108 andgrooves 107 on the bottom and top of each non-polystyrene insulated concrete form enhance wall stability and alignment of non-polystyrene insulated concrete forms in the vertical plane of the wall during construction prior to the wall forms being filled with concrete. - Furthermore, the non-polystyrene insulated concrete form's double
middle web 104 with its middle webintegral slot 110 serves to provide for the precise location of horizontalreinforcement bar holders 210. The doublemiddle web 104 with its middle webintegral slot 110 also functions as a cutting guide whereby twohalf forms 100 may be realized by cutting through the form's 100 side walls in alignment with the slot. - An advantage in the present invention of the horizontal
reinforcement bar holder 210 provides for a positive and precise location of single or multiple horizontal reinforcement bars 210 within the horizontalbond beam cavity 109 of the wall. This ensures the reinforcement bars 211 can be positioned according to the drawings and specifications of the construction project. This precise positioning of thehorizontal reinforcement 211 better ensures a more complete structural performance of the reinforced concrete as a building element as well as the more complete envelopment of the reinforcement bars by the concrete since, with the present invention, the reinforcement bars 211 do not rest on the bottom of the horizontalbond beam cavity 109 as has been traditionally the case with other prior art concrete forms. - The vertical-to-horizontal reinforcement bar holder assembly provides for a positive and precise location of single or multiple vertical reinforcement bars 213 within the vertical cavities of the wall. This precise positioning of the
vertical reinforcement 213 better ensures a more complete structural performance of the reinforced concrete as a building element as well as the more complete envelopment of the reinforcement bars 213 since, with the present invention, the reinforcement bars 213 are not inserted into the vertical cores after the concrete has filled the cores as has been traditionally the case with other prior art concrete forms. - Accordingly, it will be understood that those skilled in the art that the simplified non-polystyrene permanent insulating concrete form building system of this invention can be used to produce walls that are strong, more precise and simpler to build.
- Although the description above contains much specificity, the specific items illustrated should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. For example, the non-polystyrene insulated concrete forms can be manufactured in differing sizes and have other shapes such as trapezoidal, circular, oval, triangular, etc.; the fastening clamp may be combined with reinforcement bar holders for transverse orientation of the forms when a super thick wall assembly may be required for locations of climatic extremes, etc.; the
horizontal reinforcement holders 210 and/or 220 can have additional bar holder saddles for a single pair of support legs, etc. - Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
- While the preferred embodiment to the invention has been described, it will be understood that those skilled in the art, both now and in the future, may make various improvements and enhancements which fall within the scope of the claims which follow. These claims should be construed to maintain the proper protection for the invention first described.
