Description
The present invention relates to a concrete form system, and in particular it relates to a concrete form system, used in the construction of low rise commercial, and high performance residential construction, or similar constructions.
For many years, all over the world, concrete with steel reinforcing bar ( rebar) has been a common method of construction. Also for many years, the use of various disposable or reusable wood forms, [or almost aU types of concrete forming has been a general forming method. However, wood forming, the most common and previously cost effechve opUon, has been chaflenged as a resutt of worldwide resthctions on harvesting, and the need to utffize a diminishing resource in a highest cost, and best use fasho r. Also, costs have increased sign hcari tly [or plywood and dimensional i m ber.
RecenUy, reusable wood or metal frames have become popular for concrete construclion. Even though these tornis are usetul in many apphcations, and less wastefuL these forms cUll provide construction engineers with unsolved problems. That s, these must stifi be assembled, disassembled, cleaned and removed from the job site and stored. This Is a time consuming and costly process, made less practical by the nflexible nature of the large panel desigrv The resulfing concrete structure s unfinished both inside and ouL Thus, various alternatives o wood have been tested and advanced, as viable replacements so far. These include steel, concrete blocks and various vinyl composites, which are removed or remain in place.
There are various stay-in-place ( SIP) forming systenis. One of the SIP forming systems, is commonly called Insulating Concrete Formwork ( CF). OF systems are currently manufactured from polystyrene foam (expanded or extruded), polyurethane foam (including soy based), cement bonded polystyrene heads, cement bonded wood fiber. and cellular concrete. Th.e most common, and most practical and successful of these, is expanded polystyrene foam (EPS).
The systems consist of twinwalied, lightweight EPS panels or blocks, with plastic spacers which also locate the rebar. The forms lock together somewhat like Lego (RTM) bricks, and serve to create a form for the structural walls or floors of a building. Rebar is put into the cavity, and this forrnwork is then filled with factory produced, quality assured, ready-mixed concrete, usually pumped into the fomiwork, to create a robust structure, The expanded polystyrene blocks remain in place, to provide thermal insulation, and the reinforced concrete core provides robustness and sound insulation.
ICF construction has become commonplace for both low rise commercial, and high performance residential construction, as more stringent energy efficiency and natural disaster resistant building codes, are adopted.
There are many advantages in using an EPS block ICF system, over conventional construction systems, but there are some unsolved problems, which have restricted its use.
EPS can easily be manufactured into the shapes required, but it has no rigidity in itself. It is not dimensionally stable under load, that is, it can flex and distort under the pressure of wet concrete. This means the form structure must be braced, to prevent blowout, or distortion, when the wet concrete is pumped into the form structure. Also there is a practical limit to the height of the walls, that can be filled with concrete at the same time, which often means in practice that the contractors err on the side of caution, and do not pour the complete wall, but allow the concrete to partly set, to relieve the pressure on the formwork. This then makes "joints" in the concrete, which can weaken the final structure. When the concrete in the walls and floors have set, the EPS stays in place, and acts only as an insulating layer. Both sides of the concrete are still effectively unfinished; waterproofing and cladding or external plaster systems have to be attached to the outside, and normally the inside is plaster boarded and skimmed to obtain the final surface, ready for decorating.
In recent years there has been a philosophy, and regulations by some governments, to develop Passive and Low-energy house standards. These are buildings which assure a comfortable indoor climate in summer and in winter, without needing a conventional heating or cooling system. Often an integral part of the system is that the construction has a large thermal mass. This is normally achieved by constructing using concrete walls and floors. The outside is then highly insulated, and the concrete mass on the inside, passively controls fluctuations in temperature. The construction methods used are factory precast concrete panels, which are craned into position, in situ pumped concrete into reusable concrete forms, or laying and mortaring concrete blocks. Each has their own disadvantages. The concrete walls are then insulated on the outside, but are difficult to decorate on the inside. If the inside is plastered, or plaster boarded, using normal plasters, this has the effect of insulating the walls and counteracting the thermal mass benefits. ICF systems made from EPS are not suitable, as the EPS insulates the concrete core from the air inside the building.
There has also been a trend towards more minimalist designs, and less use of carpets and curtains. There is a definite trend towards hard surface floors, such as wood, ceramic tiles and polished concrete, and blinds or shutters, instead of curtains.
Normally the inside decor is plain, smooth plastered, hard surfaces. The result has been more problems of sound reflection and echo in these constructions. The usual solution is to install sound absorbers.
The finished surfaces of the construction, ideally should have different properties, depending on whether they are the outside surface, or the inside walls or ceiling surfaces of the construction. Ideally the outside surface of the construction should be durable, waterproof, dimensionally stable with temperature and humidity, thermally and acoustically insulating, rot proof, fire resistant, and rodent and insect resistant. Ideally the inside surfaces should be durable, dimensionally stable with temperature and humidity, fire resistant, sound absorbing, not damaged by water, and should be permeable to liquid water, air and water vapour. To be commercially viable, it should be able to be decorated easily, to suit different tastes and cultures.
There is therefore a need for a lightweight form block system, that is made from a material that can be manufactured accurately, into a rigid and dimensionally stable block, that can be locked together, that provides a concrete formwork that is structurally strong enough, to pour a full wall height in one pour, with minimal distortion, and that stays in place to provide the finished surfaces of the construction, with properties suitable for their position in the construction.
To meet those needs, this invention provides a concrete form block system, made from bonded expanded glass granules, which stays in place after construction, and the formwork provides the permanent final surfaces of the walls and ceilings of the construction.
The properties of bonded expanded glass granules, give to the SIP concrete Form system, many SouLofl5 Lo the problems of prior art systems, and many advantages over phor art systems. The advantages are described b&ow, in no order of importance.
The block can be manufactured accurately, into a dimerisionaHy stable Form block, it w not warp, flex, or crack, and that when locked together, will produce outer surfaces that provkie surfaces of sufficient accuracy and unitorrnfty, so they can be prepared. by repairing any damage, then directly decorated. By using different sizes of expanded glass granules, different bonding techniques, and with coatings applied in the manufacturing process, the sides of the form block can be manufactured to have different properfles.
The compostion of the bondng agent, and the texture of the block surface, means that when erecting the lbrm blocks, they can be easily glued together, using the same bonding agent, with. effectively no thickness of joint. This makes the wall form blocks integrated, which imparts added structural integrity to the completed formwork.
This reduces considerably any risk of blowout, and reduces the risk of movement which would after the uniformity of the nal surfaces. A form block waH, constructed and glued together, has some structural strength, rigidity, and compression properfies within itself, withoul the addiflon of the reinforced concrete. This wifl reduce the thickness of concrete required. and consequently costs, the exact requrement will have to be caculaLed by structural engineers, to satisfy local building regulations.
No tftckness of loini, also means there wifi be rio joint gap, which would have to be fified before final decoration. On the outside, normal waterproof, spray render systems, will be easy to apply, with minknal preparahon of the surface. For aesthetic reasons, or local styles, or regulations, cladding or other decorated surfaces, will be easy to glue or fix to the outer surface. On the inside surfaces of the walls and ceilings, the surface can be sprayed or skimmed with a specialist skim coat, made from the same glass granules and binders, so that the properties are not altered, This wil! give a durable, breathable, aesthetically pleasing, clean and uniform, normally mart white surface, which can be over painted, or further decorated, [required.
The breathable nature of the inside rnater will help to regulate humidfty levels, mitigate mould growth. allow the concrete core to dry during the construction, and allow the concrete core lo efficiently act as a thermal mass, making this invention the only ICF system that can be used for the thermal mass effect, and which allows for a surface which is more aesthetically pleasing. rather than bare or painted concrete.
The comoosition of the form blocks, that is the bonded glass granules, will provide fire resktan.ce, 1150°C for 2 hours, and high levels of sound absorption. The glass granules also give to the structure blast and ballistic resistance. The form blocks are inert, rot proof and rodent and Insect resistant. They are unaffected by temperature and hght, and are unaffected and not damaged by water. This has an moortant side effect, that is, during construction rain and extremes of temperature will riot slop the construction, nothing will need to he protected, and first fix and other processes can continue before tb:e building is watertight. There will be no wood, or gypsum plaster, in the construction! at that stage, so if all the inside walls and ceifings get wet, they will simply dry out, or industrial dehurnidifiers can quickly dry out the building. with no damage or marking. As the walls are not affected by water, this also means there will be no need for a different material for bathrooms, wet rooms and swimming pools. In t.raditiona! construction, special waterproof plaster or cement. boards, have to be used in those areas. Tiling can be applied directly onto the walls, with no preparation.
As the form blocks or the wails can be glued, as well as locking together, the building should be abie to be constructed from the inside, which will aleviate the need for scafloiding, either completely, or until later in the construction. This will depend on the type of roof construction, exterior finishing, and local regulations.
Blocks made from bonded expanded glass granules area lightweight material, specific gravity = 0.29. compared to an average brick = 200, or concrete = 232. This makes ft very cost effecflve to pafleUze and deUver to site, with no special Ifthng or unloading machines required. For the instaaUon of plumbing and electrics, it can easHy he ddHed. cut and routered, using standard woodworking look, Channek, holes and damage duhng construction, can easy be fified with a special tiUer made from the glass granules, then prepared For s kimrning.
There is aso a requirement by architects and individuals, tc design new budings to he more interesting, and less box like. Often this has been. achieved by adding curved waDs, arid round piars into the design. Th.e traditional method of building curved walls is to lay bricks or blocks, then plaster, to make the curve accurate. This is a skified, and acour intensive process, an.d consequenfly is expensive. Curved EPS block CF systems have solved part of the problem, but skilled plasterers are still needed to produce a quality finish on Ihe inside. A curved factory produced form block, made from glass granules, is the first method to produce accurate cur'ed finished waUs, wfthout reuuting skDled labour, This consequenday makes the process more viable.
Round, square, orfluted pillars, can easily be produced, with the finished surface provided by the formwork blocks.
Basement construction is normally achieved by pumping concrete into formwork, then applying insulation, and a waterproof coating, or membrane, on the outside, to make the basement watertight. The outer waU of the form block can be produced to be corrplete:y watertight and insulating, with the inner wall breathable, to allow the concrete to dry. In tight situations, where t would be duff cult to apply the outer insuation and membrane, this will be a very useful, and cost effective, solution.
In most common house construct!ons, the inside is finished by gypsum plaster, usually a comhnation of plaster hoards, and base and finish plasters. This invention removes that' process, with consequently considerable savings on cost of material, labour, and construction time. The material is more sustainable, more durable, and is not damaged by water.
The glass granules are made from recycled glass, so the system is sustainable, and as the finished product is 95% recycled glass, it will satisfy most environmental tests. This invention provides a method of constructing buildings, that are sustainable, robust, durable, thermally and acoustically insulating, fire, blast and ballistic resistant, and will satisfy the more stringent energy efficiency, and natural disaster resistant building codes, that are being adopted. lithe use of concrete made from steel slag and fly ash was more widely adopted, then constructions using this invention will be made primarily from recycled materials, and as such will be more sustainable than any current systems.
The invention provides a concrete form block system, made from bonded expanded glass granules. When the product is in production, there will be many components required for the system, such as corner blocks, adjoining wall blocks, ceiling blocks, curved blocks, lintel blocks, window opening stops, etc. So I will describe in detail the basic wall block, which will be the main component, and the detail of the other components will mainly differ only in shape and size.
An embodiment of the invention will now be described, by way of example only, and with reference to the accompanying drawings, in which Fig. 1 shows a perspective view of a wall block; Fig. 2 shows a cross sectional view of a wall block.
Referring to Figs. 1 and 2, the wall form block 20 comprises an outer wall 21 and an inner wall 22, joined together by plastic spacers 24. An outer wall 21 means a wall of the block, where the outer surface of the block 26 is the final surface on the outside of the construction. An inner wall 22 means a wall of the block, where the outer surface of the block 28 is the final surface on the inside of the construction. In the case of internal dividing walls of the construction, the form block 20 would be composed of 2 block walls 22.
The plastic spacers 24 lock the sides of the block together, to provide an accurate form to pour the concrete 23. The thickness of concrete is determined by the length 32 of the spacer 24. The most common thicknesses at present are 10cm, 15cm, and 20 cm, whichever is used depends on the situation and design requirements.
Testing of the structural strength of the form system, will determine what will be the optimum thicknesses of concrete for different design requirements, and consequently what lengths 32 to manufacture the spacers 24. The walls 21 and 22 will be manufactured with accurate holes 30 in the inside surfaces. The plastic spacers will be manufactured with compressible spigots 31, so when they are tapped into the holes 30, they grip the inside surface of 30. The spacers 24 will be preferably injected moulded polypropylene.
The spacers 24 will be manufactured with round slots 25, these are to position, and hold in place, the horizontal rebar 41. There will be 2 slots 25 on each spacer, so that each layer of blocks will have a horizontal rebar 41 installed, but offset on each alternate layer, so that will leave a gap, to install the vertical rebar, that will be centralized and held in position by the horizontal rebar.
The walls of the blocks 21 and 22 will be manufactured with accurate tongue 33 and grooves 34 on the adjoining surfaces of the block. So when the assembled blocks are located together, the outer surfaces of the walls should be uniform and flat. The walls of the blocks 21 and 22 will be manufactured with glue grooves 35, so that an accurate line of glue can be applied that will not interfere with the tongue and groove location.
The thickness 36 of the block walls 21 and 22 will be determined by the thickness of the concrete, and composition of the block. It will preferably be in the range 4 to 6 cm.
The height 37 of the wall block 20 is determined by the horizontal rebar spacing, preferably 40 cm. The length 38 of the wall block 20 is preferably 80 cm, to be easily managed.
Expanded glass granules are available in different sizes, the most common are 1mm, 2mm and 4mm. Ground glass is also available that has been made from recycled glass. Preferably the binder is a polymeric binder, and preferably the binder is a moisture cured polyurethane binder, which will be chemically inert once cured. The reaction speed and cure time can easily be adjusted to suit the production requirements. Commercially-available MDI binders would be suitable for use in the present invention, provided they possess the appropriate chemical and physical properties, which the skilled person will be able to determine. Chopped glass fibre strands, or polypropylene strands, can also be added to the mix, which will impart dislocation resistance to the blocks, that is, will resist cracking of the block.
The specific mix, can be injected and pressed into moulds, to make accurate blocks 21 and 22. A controlled amount of a mix, can be injected, to create a layer, 27 and 29, to create surfaces on the blocks, which have different properties to the rest of the block. The depth of the layers 27 and 29 can be accurately controlled, by the quantity of the mix. These outer surface layers 27 & 29 can made from a mixture of different sizes of granules, plus pigments and other additions, to create surfaces with the properties required for their situation. The colour and texture of the surfaces 26 & 28, will also be used to differentiate the inner and outer surfaces of the building, to try to mitigate mistakes when assembling the form blocks.
There are other properties that will be easy to create, particularly to the inside block walls 22. A Phase Change Material ( PCM) can easily be added into the mix, which will mean the inner surfaces help to absorb daytime heat, then give it up to night time ventilation. PCMs absorb room heat by changing from solid to liquid within microscopic capsules, which can be incorporated into the inner blocks 22. The process is reversed when the room is cooled with night air ventilation. Also materials such as Microban can easily be added during production, this will give some bacterial resistance to the inner walls.
