ENQUADRAMENTO FRAMEWORK
[0002] O documento PT104019A descreve um dispositivo conector entre dois painéis isolantes com aplicação em cofragem perdida em construção civil, que sendo rebatível permite quer a separação entre os dois painéis de forma a receber o material estruturante fluido, como o betão, para a construção de muros e paredes, quer, quando rebatido, o contacto entre os dois painéis, de forma a facilitar o seu armazenamento e transporte o dispositivo conector é constituído por uma peça central que termina em ganchos de forma curva com abertura, e duas extremidades, cada uma das quais incluindo uma parte exterior alongada embutida num dos painéis em material isolante e uma parte interior unida à peça central, que inclui um eixo longitudinal que roda 90^ entre as duas posições pretendidas. O bloco de cofragem que inclui este dispositivo é produzido numa única peça já que o dispositivo pode ser colocado no molde onde são injetados os painéis isolantes. [0002] The document PT104019A describes a connector device between two insulating panels with application in lost formwork in civil construction, which being foldable allows either the separation between the two panels in order to receive the fluid structuring material, such as concrete, for the construction of walls and walls, or, when folded, the contact between the two panels, in order to facilitate their storage and transportation, the connector device consists of a central piece that ends in hooks with a curved shape with an opening, and two ends, each one of which including an elongated outer part embedded in one of the insulating material panels and an inner part joined to the center piece, which includes a longitudinal axis that rotates 90 ° between the two desired positions. The formwork block that includes this device is produced in a single piece since the device can be placed in the mold where the insulating panels are injected.
[0003] O documento PT1792024E apresenta um sistema de cofragem de isolamento para betão com ligações de parede de comprimento variável. Esta invenção está relacionada com as ligações variáveis que servem para a construção e formação das paredes de diversas espessuras feitas de placas de entaipamento com capacidade de carga elevada, sem utilizar o revestimento clássico. As placas de isolamento e os revestimentos de isolamento servem também para o isolamento térmico e acústico de paredes que são resistentes ao fogo. [0004] Estes factos são descritos de forma a ilustrar o problema técnico resolvido pelas realizações do presente documento. [0003] The document PT1792024E presents an insulation formwork system for concrete with wall connections of variable length. This invention is related to the variable connections that serve for the construction and formation of walls of different thicknesses made of high-capacity capping boards, without using the classic coating. Insulation boards and insulation coatings are also used for the thermal and acoustic insulation of walls that are resistant to fire. [0004] These facts are described in order to illustrate the technical problem solved by the achievements of this document.
DESCRIÇÃO GERAL GENERAL DESCRIPTION
[0005] A presente divulgação refere-se à uma forma de construção que permite através de um método de montagem de painéis que juntamente com os elementos de ligação, formam uma cofragem que se monta com a facilidade que se montam como LEGO™, colocando simultaneamente a armação em ferro estrutural e que depois se enche com betão auto-compactável, passando a cofragem perdida, ficando a ser parte integrante da construção. A referida cofragem alem da função que lhe confere o nome pode ainda efetuar várias funções, tais como, o isolamento térmico e acústico do edifício/construção, permitir a afixação no interior, aparafusando o gesso cartonado, prateleiras, móveis, espelhos, televisores etc. No exterior poderá ser feito o acabamento de igual forma ao "capoto", ou então, afixar aparafusando vários tipos de materiais tais como pedra, fenólicos etc. Isto com uma colocação rápida, simples e intuitiva. [0005] The present disclosure refers to a form of construction that allows through a method of assembling panels that together with the connecting elements, form a formwork that can be assembled with the ease that they can be assembled like LEGO ™, placing simultaneously the structural iron frame, which is then filled with self-compacting concrete, the lost formwork becoming an integral part of the construction. This formwork, in addition to the function that gives it its name, can also perform various functions, such as the thermal and acoustic insulation of the building / construction, allowing the display inside, screwing the plasterboard, shelves, furniture, mirrors, televisions, etc. On the outside, the finishing can be done in the same way as the "capoto", or else it can be fixed by screwing various types of materials such as stone, phenolics etc. This with quick, simple and intuitive placement.
[0006] A possibilidade da afixação descrita no ponto anterior é parte integrante deste sistema de cofragens de betão isolantes, não sendo necessário efetuar qualquer alteração aquando da montagem do sistema. Importa referir que é através deste sistema de fixação que se garante a verticalidade e segurança da cofragem aquando da sua montagem aparafusando os aprumadores/andaimes nos pontos de fixação. Os pontos que permitem afixação serão ainda detetáveis mesmo após os muros acabados e pintados como se explica mais a frente. No caso da aplicação de pedra nas fachadas e/ou outro tipo de material que seja extremamente pesado então o engenheiro de obra, se entender que a possibilidade da afixação Standard não é suficiente, deverá definir, em função das necessidades, a inclusão de mais pontos de fixação. Quer isto dizer, mais elementos de ligação entre os painéis da cofragem, ou em último caso um perfil contínuo na parte da cofragem correspondente ao lado do muro onde vai ser sujeita essa força extraordinária. É de salientar que em algum tipo de materiais, em particular a pedra será necessário um dispositivo adicional (grampo) para afixar/aparafusar nos pontos anteriormente descritos e conectar à referida pedra. [0007] Este sistema de cofragens de betão isolantes pretende ser uma solução com vantagens relativamente ao estado da técnica atendendo à sua versatilidade e preço. [0006] The display option described in the previous point is an integral part of this insulating concrete formwork system, and it is not necessary to make any changes when assembling the system. It is important to mention that it is through this fixation system that the verticality and safety of the formwork is guaranteed when assembling by screwing the uprights / scaffolding at the fixing points. The points that allow fixing will still be detectable even after the finished and painted walls, as explained later on. In the case of the application of stone on the facades and / or other type of material that is extremely heavy, then the construction engineer, if he understands that the possibility of Standard display is not enough, should define, depending on the needs, the inclusion of more points fastening. That is to say, more connecting elements between the formwork panels, or in the last case a continuous profile in the part of the formwork corresponding to the side of the wall where this extraordinary force will be subjected. It should be noted that in some types of materials, in particular the stone will require an additional device (clamp) to fix / screw in the points previously described and connect to said stone. [0007] This insulating concrete formwork system aims to be a solution with advantages regarding the state of the art, given its versatility and price.
[0008] Caso se pretenda um produto com qualidade superior, é de salientar a possibilidade de formação de sistemas híbridos onde poderão existir dois tipos de materiais nos painéis isolantes, isto é, dois tipos de poliestireno expandido, como por exemplo: O EPS (Poliestireno expandido) e o EPS X (Poliestireno expandido com características térmicas e mecânicas semelhantes ao EPS 200 e características de impermeabilidade semelhantes ao XPS (Poliestireno extrudido)). Neste caso o EPS X pode ser usado no fabrico dos painéis para serem usados na parte da cofragem correspondente ao exterior da construção, devido as suas características superiores de impermeabilidade. Sendo uma das principais aplicações em muros ou estruturas que estejam soterrados como, por exemplo, caves e/ou fundações de edifícios. Note-se a possibilidade do uso de outros compostos de poliestireno, como por exemplo, o grafitado ou outro tipo de materiais cujos quais possam ter características especiais para determinada finalidade e permitam resistências mecânicas e baixa condutividade térmicas adaptável ao efeito pretendido. Outra possibilidade é a de usar o mesmo tipo de poliestireno no fabrico dos painéis mas com espessuras diferentes dos painéis isolantes, por exemplo, a espessura Standard e outra mais espessa, esta última a ser usada na parte da cofragem correspondente ao exterior do edifício, isto para climas onde as exigências de isolamento térmico são superiores ou caso os clientes pretendam um isolamento térmico superior. [0008] If you want a product with superior quality, it is worth noting the possibility of forming hybrid systems where there may be two types of materials in the insulating panels, that is, two types of expanded polystyrene, such as: EPS (Polystyrene expanded) and EPS X (expanded polystyrene with thermal and mechanical characteristics similar to EPS 200 and waterproof characteristics similar to XPS (extruded polystyrene)). In this case, EPS X can be used in the manufacture of the panels to be used in the part of the formwork corresponding to the exterior of the building, due to its superior impermeability characteristics. Being one of the main applications in walls or structures that are buried as, for example, cellars and / or foundations of buildings. Note the possibility of using other polystyrene compounds, such as graphite or other types of materials, which may have special characteristics for a given purpose and allow mechanical resistance and low thermal conductivity adaptable to the desired effect. Another possibility is to use the same type of polystyrene in the manufacture of the panels but with different thicknesses of the insulating panels, for example, the Standard thickness and a thicker one, the latter to be used in the formwork part corresponding to the exterior of the building, that is for climates where thermal insulation requirements are higher or if customers want superior thermal insulation.

DETAILED DESCRIPTION
[0057] A presente divulgação refere-se a um sistema simplificado no que respeita a forma como se monta um sistema de cofragens de betão isolantes para fabrico de muros ou estruturas em construção civil. São usados apenas três tipos de matérias-primas: EPS (poliestireno expandido), PVC (Policloreto de vinilo) e Aço. [0057] This disclosure refers to a simplified system with regard to the way in which an insulating concrete formwork system is assembled for the manufacture of walls or structures in civil construction. Only three types of raw materials are used: EPS (expanded polystyrene), PVC (polyvinyl chloride) and Steel.
[0058] Na figura 1 está apresentada uma realização do sistema de cofragens de betão isolantes com painéis isolantes e elementos de ligação que compreende: pelo menos dois painéis (1,5); um ou mais dispositivos conetores (2,7) para ligação dos painéis (1,5) de forma a criar/disponibilizar o espaço (6) para receber o material estruturante fluído; pelo menos dois perfis (3) para encaixarem nos painéis (1,5) interligados pelos referidos dispositivos conetores (2,7); em que os painéis (1,5) compreendem ao comprimento uma cavidade (10) no referido painel (1,5) para encaixar um ou mais perfis (3); em que os perfis (3) compreendem um rufo lateral (11) com uma pluralidade de furos (12) para encaixarem os dispositivos conectores (2,7); em que os dispositivos conetores (2,7) compreendem uma pluralidade de ganchos (16) adaptados para entrarem axialmente nos furos (12) dos referidos perfis (3). [0058] In figure 1, an embodiment of the insulating concrete formwork system with insulating panels and connecting elements is presented, comprising: at least two panels (1,5); one or more connector devices (2,7) for connecting the panels (1,5) in order to create / make available the space (6) to receive the fluid structuring material; at least two profiles (3) to fit the panels (1,5) interconnected by said connector devices (2,7); wherein the panels (1,5) comprise at length a cavity (10) in said panel (1,5) for fitting one or more profiles (3); wherein the profiles (3) comprise a side flash (11) with a plurality of holes (12) for engaging the connector devices (2,7); wherein the connector devices (2,7) comprise a plurality of hooks (16) adapted to axially enter the holes (12) of said profiles (3).
[0059] O EPS para fabrico de painéis (1,5), conforme figura 2, pode ser fornecido em blocos de grandes dimensões. O PVC para o fabrico de perfis (3), conforme figura 3, pode ser fornecido já em perfis. O aço para fabrico dos dispositivos conetores (2,7), conforme figura 4, pode ser fornecido em chapas de eletrosoldado em aço cru. [0059] EPS for panel manufacture (1.5), as shown in figure 2, can be supplied in large blocks. The PVC for the manufacture of profiles (3), as shown in figure 3, can be supplied already in profiles. The steel for the manufacture of the connector devices (2,7), as shown in figure 4, can be supplied in electrowelded sheets in raw steel.
[0060] O painel (1,5), conforme figura 2, pode ser fabricado a partir de blocos fornecidos em grandes dimensões com auxílio de uma cortadora de espumas, do inglês foam cutter, que pode ser um pantógrafo. Sendo esta uma característica peculiar no fabrico dos painéis da presente divulgação, pois é a primeira solução a usar o sistema de corte para o fabrico de painéis em sistemas de cofragens isolantes. Poderão ser usados vários tipos de densidades consoante o tipo de resistência mecânica necessária para a cofragem de acordo com a execução das respetivas espessuras das construções. Importa referir que os painéis podem compreender outro tipo de compostos de poliestireno, tais como, EPS X, Poliestireno grafitado etc., a fim de satisfazer outras necessidades, tais como, superior impermeabilidade, proteção contra raios UV ou outras especificidades. Ou ainda poderão ser usadas outro tipo de espumas que compreendam a possibilidade do corte neste tipo de máquinas e que disponham de condutibilidade térmica baixa e resistência mecânica para o efeito aqui pretendido. [0060] The panel (1.5), according to figure 2, can be manufactured from blocks supplied in large dimensions with the aid of a foam cutter, from the English foam cutter, which can be a pantograph. This being a peculiar feature in the manufacture of the panels of the present disclosure, as it is the first solution to use the cutting system for the manufacture of panels in insulating formwork systems. Various types of densities can be used depending on the type of mechanical strength required for the formwork in accordance with the construction thicknesses. It is important to mention that the panels can comprise another type of polystyrene compounds, such as EPS X, Graphite Polystyrene, etc., in order to satisfy other needs, such as, superior impermeability, protection against UV rays or other specificities. Or, other types of foams may be used that understand the possibility of cutting in this type of machines and that have low thermal conductivity and mechanical resistance for the purpose intended here.
[0061] O painel de EPS foi criado, desenhado e desenvolvido especificamente para este sistema de cofragens isolantes não havendo outro igual. O painel (1,5) é composto por duas faces, a face exterior que compreende uma pluralidade de marcações na vertical, de preferência entre S a 5 marcações, voltadas para fora da cofragem, oposta a face interior voltada para dentro da cofragem. O referido painel (1,5) possui ainda quatro topos, sendo um topo superior horizontal, compreendendo ao comprimento uma cavidade (10) e um topo inferior horizontal oposto ao superior que compreende também ao comprimento uma cavidade (10) oposta a cavidade do topo superior conforme figura 2. [0061] The EPS panel was created, designed and developed specifically for this insulating formwork system and there is no other one like it. The panel (1,5) is composed of two faces, the outer face comprising a plurality of vertical markings, preferably between S to 5 markings, facing away from the formwork, opposite the inner face facing the formwork. Said panel (1,5) also has four tops, with an upper horizontal top, comprising a cavity (10) in length and a horizontal lower top opposite to the upper one, which also comprises in length a cavity (10) opposite the top cavity. top as shown in figure 2.
[0062] O topo superior horizontal compreende ainda ao comprimento uma reentrância (8), e o topo inferior compreende ainda ao comprimento uma protuberância (9) conforme figura 2. O topo esquerdo vertical oposto ao topo direito compreende à altura uma reentrância e protuberância (15,14), e o topo direito vertical compreende à altura uma protuberância e reentrância (15,14) opostas ao topo esquerdo conforme figura 2. Entende-se como topo superior, ao topo horizontal voltado para cima, topo inferior ao topo horizontal voltado para baixo, topo esquerdo, ao topo vertical voltado a esquerda e topo direito ao topo vertical voltado a direita, isto quando visualizamos frontalmente a face exterior que deverá ter uma pluralidade de marcações, de preferência 3 a 5, pintadas na vertical. O painel (1,5) poderá ter 1200mm de comprimento. Este comprimento tem como objetivo ter a mesma largura dos painéis de gesso cartonado (Pladur), é imperativo que as medidas coincidam de forma que ao instalartudo seja fácil e intuitivo sem ter que efetuar cortes desnecessários no respetivo gesso cartonado. Nos painéis (1,5) os comprimentos inferiores necessários serão cortados através de um serrote ou de uma foam cutter manual aquando da montagem do sistema na execução da obra permitindo assim uma pluralidade infinita de variantes tornado o sistema versátil e adaptável para qualquer situação. Entende-se como comprimento à distância que separa o topo esquerdo do topo direito. A espessura do painel (1,5) mínima poderá ser de 63 mm para que seja possível colocar sem dificuldades dentro desta espessura as caixas de aparelhagem elétricas mais profundas e poderá superar 200 mm, conforme figura 13, a fim de efetuar cofragens com isolamento térmico superior que podem ser aplicadas em zonas onde o clima assim o exija. É de referir que esta é uma das muitas características que diferencia este sistema aos outros existentes pois permite escolher e adaptar o isolamento pretendido na cofragem a todos os tipos de climas e aos clientes mais exigentes, isto tendo em conta que o cliente praticamente só terá de pagar a mais a matéria-prima correspondente ao maior volume de EPS. Entende-se como espessura a distância compreendida entre a face exterior e a face interior do referido painel (1,5). A altura do painel (1,5) normal pode ser de 250 mm ou de 333 mm, esta última para executar construções de espessuras inferiores onde a necessidade de resistência mecânica da cofragem é menor. Entende-se como altura à distância compreendida entre o topo superior e o topo inferior. [0062] The top horizontal top also comprises a recess (8) in length, and the bottom top further comprises a protuberance (9) as shown in figure 2. The vertical left top opposite the right top comprises a recess and protuberance ( 15,14), and the right vertical top comprises at the height a protuberance and recess (15,14) opposite to the left top as shown in figure 2. It is understood as the upper top, the horizontal top facing up, the lower top of the horizontal top facing down, top left, to the top vertical facing left and top right to the vertical top facing right, this when we frontally view the outer face that should have a plurality of markings, preferably 3 to 5, painted vertically. The panel (1.5) can be 1200mm long. This length aims to have the same width as plasterboard panels (Pladur), it is imperative that the measurements coincide so that installing everything is easy and intuitive without having to make unnecessary cuts in the respective plasterboard. In the panels (1.5), the required lower lengths will be cut using a handsaw or a manual foam cutter when assembling the system in the execution of the work, thus allowing an infinite plurality of variants making the system versatile and adaptable to any situation. Length is understood as the distance that separates the top left from the top right. The minimum thickness of the panel (1.5) may be 63 mm so that it is possible to place the deepest electrical equipment boxes without difficulty within this thickness and may exceed 200 mm, as figure 13, in order to make formwork with superior thermal insulation that can be applied in areas where the climate requires it. It is worth mentioning that this is one of the many characteristics that differentiates this system from the others, as it allows choosing and adapting the desired insulation in the formwork to all types of climates and to the most demanding customers, taking into account that the customer will practically only have to overpay the raw material corresponding to the highest volume of EPS. Thickness is understood to mean the distance between the outer face and the inner face of said panel (1,5). The height of the normal panel (1.5) can be 250 mm or 333 mm, the latter for executing constructions of lower thicknesses where the need for mechanical strength of the formwork is less. Height is understood to mean the distance between the top and bottom top.
[0063] Nas realizações acima descritas, as medidas apresentadas poderão variar, isto é, podendo ser ligeiramente alteradas a fim de um melhor aproveitamento da matéria- prima e redução de custos do produto no fabrico. [0063] In the achievements described above, the measures presented may vary, that is, they may be slightly altered in order to make better use of the raw material and reduce product costs in manufacturing.
[0064] De acordo com a figura 2, os painéis (1,5) compreendem 3 marcações pintadas verticalmente, representadas a tracejado, localizadas a cada 300mm, que servirão de referência para a colocação dos dispositivos conetores (2,7), para o posicionamento correto do intercalar dos painéis (1,5), e para que o eletricista e o canalizador saibam onde estão colocados os perfis (3) contornando-os ao efetuar os rasgos para a inclusão das respetivas tubarias sem perda de tempo. Por fim para que se possa afixar/aparafusar o gesso cartonado aos perfis (3) de uma forma simples, intuitiva e rápida. [0064] According to figure 2, the panels (1,5) comprise 3 vertically painted markings, represented in dashed lines, located every 300mm, which will serve as a reference for the placement of the connector devices (2,7), for the correct positioning of the interlayer of the panels (1,5), and so that the electrician and the plumber know where the profiles (3) are placed, bypassing them when making the slots for the inclusion of the respective tubes without wasting time. Finally, so that the plasterboard can be fixed / screwed to the profiles (3) in a simple, intuitive and fast way.
[0065] Conforme ilustrado na figura 2, o painel (1,5) compreende no topo superior ao comprimento uma reentrância que serve para alojar o rufo lateral do perfil. Os painéis (1,5) compreendem ainda no topo inferior, ao comprimento uma protuberância (9), com a finalidade de efetuar um filtro, conforme figura 12, uma vez que ao ser pressionado um painel sobre outro, amassa a extremidade da referida protuberância na zona dos arames, dos dispositivos conetores (2,7), criando uma selagem e impedindo a passagem do betão colocado no espaço (6) entre as paredes das cofragem para as zonas das reentrâncias (8) dos painéis (1,5) a fim de não comprometer o isolamento térmico do conjunto. [0066] Numa realização, os perfis (3) compreendem um rufo lateral (11) com uma pluralidade de furos (12) para encaixarem os dispositivos conectores (2,7). [0065] As shown in figure 2, the panel (1,5) comprises at the top superior to the length a recess that serves to house the lateral ruff of the profile. The panels (1,5) also comprise a protuberance (9) at the bottom top, with the purpose of making a filter, as shown in figure 12, since when pressing one panel over another, it kneads the end of said protuberance. in the area of the wires, of the connector devices (2,7), creating a seal and preventing the passage of the concrete placed in the space (6) between the walls of the formwork to the areas of the recesses (8) of the panels (1,5) a in order not to compromise the thermal insulation of the set. [0066] In one embodiment, the profiles (3) comprise a side flash (11) with a plurality of holes (12) for engaging the connector devices (2,7).
[0067] Os painéis (1,5) estão adaptados com as cavidades (10) ao comprimento do topo superior e ao comprimento do topo inferior de forma oposta para encaixarem os perfis (3) e se interligarem os referidos painéis (1,5) uns aos outros de forma sobreposta e intercalada formando uma parede da referida cofragem que juntamente com os ganchos (16) das extremidades dos referidos dispositivos conetores (2,7), isto é, as pontas das varetas/ganchos (16), que passam através dos furos (12), localizados no rufo lateral (11) dos perfis (3), interligando assim outra parede oposta formando assim a cofragem conforme figura 1. Conforme apresentado na figura 11, a reentrância (8) serve também, para que caso a água penetre com resíduos de betão, estes não subam e entrem na cavidade (10) criada para alojar o perfil (3). Por outro lado, serve para deixar repousar/depositar os referidos resíduos, conforme apresentado na figura 12, a fim de não comprometer o isolamento térmico do sistema. [0067] The panels (1,5) are adapted with the cavities (10) to the length of the upper top and the length of the lower top in an opposite way to fit the profiles (3) and interconnect said panels (1,5) to each other in an overlapping and interspersed form forming a wall of said formwork which together with the hooks (16) of the ends of said connector devices (2,7), that is, the tips of the rods / hooks (16), which pass through of the holes (12), located in the side ridge (11) of the profiles (3), thus interconnecting another opposite wall thus forming the formwork as shown in figure 1. As shown in figure 11, the recess (8) also serves, for which case the water penetrates with concrete residues, they do not go up and enter the cavity (10) created to house the profile (3). On the other hand, it serves to let said residues rest / deposit, as shown in figure 12, in order not to compromise the thermal insulation of the system.
[0068] Numa realização um painel (1,5) dispõe de uma protuberância (14) à altura do topo direito e uma reentrância (15) à altura do topo esquerdo, verticalmente opostas junto a face interior do referido painel (1,5), que ao unir os painéis (1,5) de forma contígua, forma um encaixe perfeito para que o betão não vaze a parede da cofragem mesmo caso haja alguma folga nesta união, conforme apresentado na parte inferior da figura 9, e permaneça no espaço (6) em contacto com as faces interiores dos referidos painéis (1,5). [0068] In one embodiment, a panel (1.5) has a protuberance (14) at the height of the right top and a recess (15) at the height of the left top, vertically opposite the inner face of said panel (1.5) , which when joining the panels (1,5) in a contiguous way, forms a perfect fit so that the concrete does not leak into the formwork wall even if there is some gap in this union, as shown at the bottom of figure 9, and remains in the space (6) in contact with the inner faces of said panels (1,5).
[0069] Numa realização, um painel (1,5) dispõe de uma protuberância e reentrância (14,15) à altura do topo direito e uma reentrância e protuberância (15,14) à altura do topo esquerdo, verticalmente opostas que ao unir os painéis (1,5) de forma contígua, forma um encaixe perfeito para que o betão não vaze a parede da cofragem mesmo caso haja alguma folga nesta união. [0069] In one embodiment, a panel (1,5) has a protrusion and recess (14,15) at the height of the right top and a recess and protuberance (15,14) at the height of the left top, vertically opposite that when joining the panels (1,5) contiguously, form a perfect fit so that the concrete does not leak into the formwork wall even if there is some gap in this joint.
[0070] O perfil (3) fabricado em PVC é um perfil com características únicas pois não há igual e foi criado especificamente para esta solução de ICF. O PVC usado na presente realização pode ser enrijecido para garantir uma resistência mecânica não só para o efeito de carregamento da cofragem, mas também para poder com cargas significativas se for submetido na colocação dos vários elementos referidos anteriormente. Para a deteção destes elementos é colocado um material metálico (13), preferencialmente uma banda em alumínio e/ou pintura, como ilustrado na figura 3, que permite depois das paredes acabadas a deteção com um detetor de metais de proximidade "pinpointer". [0070] The profile (3) made of PVC is a profile with unique characteristics as there is no equal and was created specifically for this ICF solution. The PVC used in the present realization can be stiffened to guarantee a mechanical resistance not only for the effect of loading the formwork, but also to be able to carry significant loads if subjected to the placement of the various elements mentioned above. To the detection of these elements, a metallic material (13) is placed, preferably an aluminum band and / or paint, as shown in figure 3, which allows the detection with a metal detector of proximity "pinpointer" after the finished walls.
[0071] A função de deteção só é necessária após a conclusão e pintura dos muros. O confluir das linhas pintadas no painel anteriormente referidas torna o sistema intuitivo, não sendo necessário usar esta funcionalidade enquanto se constrói os muros até a colocação do gesso cartonado. [0071] The detection function is only necessary after completing and painting the walls. The confluence of the lines painted on the panel mentioned above makes the system intuitive, so it is not necessary to use this functionality while building the walls until the plasterboard is installed.
[0072] Numa realização, o perfil (3) pode ter a espessura de 3 mm e um formato parecido com "T" deitado onde a sua "perna" faz um "S", isto é, em dobra e contra dobra, ao qual se dá o nome de rufo lateral e que na sua extremidade pode ter 4mm de espessura (zona logo após onde serão efetuados os furos (12)) para a colocação dos dispositivos conetores (2,7) de forma a que a sua resistência mecânica seja fortalecida. É de salientar que cada união completa (dispositivos conetores (2,7) + perfil (3)), conforme figura 5, devido ao PVC enrijecido e espessura superior referida anteriormente terá a particularidade de aguentar uma força de tensão (lateral) próxima a 200kg a uma temperatura de 20^C. [0072] In one embodiment, the profile (3) can have a thickness of 3 mm and a shape similar to "T" lying where its "leg" makes an "S", that is, in fold and against fold, to which it is called a lateral flash and which at its end can be 4mm thick (area just after where the holes (12) will be drilled) for the placement of the connector devices (2.7) so that its mechanical resistance is strengthened. It should be noted that each complete joint (connector devices (2.7) + profile (3)), as shown in figure 5, due to the stiffened PVC and superior thickness referred to above, will have the particularity of withstanding a tension force (lateral) close to 200kg at a temperature of 20 ° C.
[0073] O perfil (3) pode ser cortado e furado para que juntamente com os dispositivos conetores (2,7), conforme figura 4 formem as uniões conforme figura 5 e que encaixadas nas cavidades (10) dos painéis (1,5) colocados paralelamente opostos, formem a cofragem (ICF), conforme figura 1 e 10. [0073] The profile (3) can be cut and drilled so that together with the connector devices (2,7), as shown in figure 4, form the joints as shown in figure 5 and that fit into the cavities (10) of the panels (1,5) placed parallel to each other, form the formwork (ICF), as shown in figures 1 and 10.
[0074] Importa referir que para cantos, topos, cruzamentos e entroncamentos de muros é usado o mesmo perfil (3) cortado com as respetivas dimensões, dobrado e furado, conforme ilustrado na figura 6, ao qual junto com os dispositivos conetores (2,7) e os painéis (1,5) fará os formatos referidos, conforme apresentado na figura 7. [0074] It should be noted that for the corners, tops, intersections and junctions of walls, the same profile (3) cut with the respective dimensions, folded and punctured, as shown in figure 6, is used, which together with the connector devices (2, 7) and the panels (1,5) will make the formats mentioned, as shown in figure 7.
[0075] Numa realização, conforme figura 4, os dispositivos conectores (2,7) podem ser fabricados em electrosoldado em aço cru. As varetas metálicas transversais com cerca de 100 mm apresentados nestes dispositivos conetores servem para manter a esquadria dos mesmos e do sistema, mas também para poder atar a armação de ferro estrutural aquando da montagem deste sistema de cofragens isolantes. A dimensão destas varetas é meramente indicativa e está relacionada com o custo e velocidade do fabrico. Caso se verifique que na montagem e/ou colocação do ferro estrutural a dimensão dos travessões anteriormente referida condicione a velocidade da execução esta medida passará para o mínimo possível e exequível pelas máquinas de corte e fabrico. [0075] In one embodiment, as shown in figure 4, the connector devices (2,7) can be manufactured in electrowelded steel. The transverse metal rods of about 100 mm presented in these connector devices serve to maintain the square of them and the system, but also to be able to tie the structural iron frame when assembling this insulating formwork system. The dimension of these rods it is purely indicative and is related to the cost and speed of manufacture. If it is found that when assembling and / or placing the structural iron, the size of the aforementioned crossbars affects the speed of execution, this measure will pass to the minimum possible and feasible by the cutting and manufacturing machines.
[0076] Numa realização, os dispositivos conectores (2,7) podem ser fabricados em electrosoldado em aço cru. As varetas metálicas transversais, i.e. perpendiculares com cerca de 100 mm apresentados nestes dispositivos conetores servem para manter o paralelismo dos arames e a esquadria dos mesmos e do sistema. [0076] In one embodiment, the connector devices (2,7) can be manufactured in electrowelded steel. The transverse metal rods, i.e. perpendicular with about 100 mm presented in these connector devices, serve to maintain the parallelism of the wires and the square of them and the system.
[0077] Os dispositivos conectores (2,7) podem ter várias medidas de comprimento que servem para em conjunto com o perfil (3) formar a união entre as paredes da cofragem, conforme apresentado na figura 5. Importa referir que é o comprimento destes dispositivos conetores que define o espaço no interior da cofragem e consequentemente a espessura do muro e/ou construção. Estão previstos o fabrico de dispositivos conetores (2,7), com vários comprimentos conforme figura 4 de forma a permitir que os muros/construções compreendam aproximadamente 10, 15, 20, 25, 30, 35 cm de espessura. Estas são as medidas Standard, podendo ser feitas outras medidas pedidas por encomenda, seja para muros com mais espessura, seja para execução de cofragens para pilares de maiores dimensões com uso de ICF ou outro tipo de cofragens específicas da obra/construção em questão. [0077] The connector devices (2,7) can have several length measures that, together with the profile (3), form the union between the walls of the formwork, as shown in figure 5. It is important to mention that it is the length of these connector devices that define the space inside the formwork and consequently the thickness of the wall and / or construction. The manufacture of connector devices (2,7), with various lengths, as shown in figure 4, is planned in order to allow the walls / constructions to comprise approximately 10, 15, 20, 25, 30, 35 cm in thickness. These are the Standard measures, and other measures can be ordered by order, either for thicker walls, or for the formwork of larger columns using ICF or other type of formwork specific to the work / construction in question.
[0078] Outra finalidade dos dispositivos conectores (2,7) é o de apoiar e atar a armação de ferro estrutural ajudando a sua colocação e passando a fazer parte da mesma. [0078] Another purpose of the connector devices (2,7) is to support and tie the structural iron frame, helping its placement and becoming part of it.
[0079] Numa realização, conforme ilustrado na figura 5, a união completa (dispositivo conetor com perfis (3) opostos), sendo os perfis (3) interligados pelos dispositivos conetores que encaixados nas cavidades (10) dos painéis (1,5) garantem a segurança do sistema e é a estes que podem ser aparafusados todos os elementos: Gesso cartonado, estantes, televisores, quadros, armários, fenólicos e até será possível colocar revestimentos de elevado peso pois cada uma destas uniões terá a particularidade de aguentar pesos próximos dos 200kg. São aos perfis (3) que também podem ser aparafusados os aprumadores aquando da montagem da cofragem, os quais garantem a verticalidade do sistema e segurança da cofragem até a secagem do betão. É de salientar também que quando se façam as orlas das portas e janelas com cofragem usando os topos apresentados na figura 7, criamos a possibilidade de afixar as janelas e portas diretamente ao sistema com a máxima segurança e rapidez sem ter que fazer furos e/ou colocar buchas. [0079] In one embodiment, as shown in figure 5, the complete joint (connector device with opposite profiles (3)), the profiles (3) being interconnected by the connector devices that fit into the cavities (10) of the panels (1.5) they guarantee the safety of the system and it is to these that all elements can be screwed: Plasterboard, shelves, televisions, pictures, cabinets, phenolic and it will even be possible to put heavy coatings because each of these joints will have the particularity of withstanding close weights 200kg. The uprights can also be screwed to the profiles (3) when assembling the formwork, which guarantee the verticality of the system and safety of the formwork until the concrete has dried. It should also be noted that when the edges of the doors and windows are made with formwork using the tops shown in figure 7, we created the possibility to affix the windows and doors directly to the system with maximum security and speed without having to drill holes and / or place dowels.
[0080] Numa realização, conforme apresentado na figura 8, os painéis (1,5) podem ser colocados contíguos, sobrepostos e intercalados onde as marcações verticais permitem com exatidão perceber a colocação das uniões e a posição certa para o intercalar dos mesmos. Isto torna tudo muito mais intuitivo na montagem assim como na colocação do gesso cartonado pois em cada cruzamento entre as linhas e a extremidade do painel haverá um perfil (3) onde se pode aparafusar o gesso cartonado. [0080] In one embodiment, as shown in figure 8, the panels (1,5) can be placed contiguous, overlapping and interspersed where the vertical markings allow to accurately perceive the placement of the joints and the right position for their interleaving. This makes everything much more intuitive in the assembly as well as in the placement of the plasterboard, since at each crossing between the lines and the end of the panel there will be a profile (3) where the plasterboard can be screwed on.
[0081] Na figura 8 estão representadas a tracejado as marcações verticais para facilitar a montagem das cofragens da presente realização. Importa referir que a presente realização não compreende as extremidades do painel (1,5) sinalizadas, conforme indicado na figura 8, e as marcações serão coloridas e espessas, preferencialmente de 2 a 3mm. [0081] In figure 8 the vertical markings are shown in dashed lines to facilitate the assembly of the formwork of the present design. It should be noted that the present design does not include the ends of the panel (1.5) marked, as shown in figure 8, and the markings will be colored and thick, preferably from 2 to 3 mm.
[0082] Na presente realização e conforme figura 8, numa realização, o sistema pode permitir pontos de afixação como nenhum sistema permite no estado da técnica. Importa referir que depois de acabado e pintado pode-se sempre saber com o detetor de metais onde estarão os perfis (3) a fim de ser aparafusados os suportes para colocação, por exemplo, um quadro ou uma televisão. Importa referir que nenhum sistema deste tipo de cofragens tem esta particularidade. [0082] In the present embodiment and according to figure 8, in one embodiment, the system can allow display points as no system allows in the state of the art. It should be noted that after finishing and painting, one can always know with the metal detector where the profiles (3) will be in order to be screwed the support for placement, for example, a picture or a television. It is important to mention that no system of this type of formwork has this particularity.
[0083] Numa realização, conforme indicado na figura 9, podemos ver como se une de forma sequencialmente e contígua os painéis (1,5), com este efeito tipo positivo/negativo, isto é, saliência/protuberância (14) e cavidade/reentrância (15) para que mesmo com alguma folga não ocorra o vazamento de betão. [0083] In one embodiment, as shown in figure 9, we can see how the panels (1.5) are joined sequentially and contiguously, with this positive / negative effect, that is, protrusion / protuberance (14) and cavity / recess (15) so that even with some play, concrete does not leak.
[0084] Numa realização, conforme figura 10, a colocação de dois painéis de forma oposta interligados com as uniões completas conforme figura 5, conjunto perfis (3) mais dispositivos conetores (2,7) formam um bloco, a forma mais simples da cofragem. Na prática a colocação destes blocos sequencialmente contíguos, sobrepostos e intercalados, formará a cofragem. [0085] Numa realização, conforme figura 11, a cavidade está preenchida pelo perfil (3), e a reentrância (8) do topo superior, aloja o rufo lateral (11) juntamente com as extremidades dos ganchos (16) dos dispositivos conetores que também serve para repousar/depositar e ali isoladamente solidificar, alguns resíduos de betão que possam passar para o interior da reentrância, a fim de não comprometer o isolamento térmico do conjunto. [0084] In one embodiment, as shown in figure 10, the placement of two opposite panels interconnected with the complete joints as shown in figure 5, set profiles (3) plus connector devices (2,7) form a block, the simplest form of the formwork . In practice, placing these blocks sequentially contiguous, overlapping and interspersed, will form the formwork. [0085] In one embodiment, as shown in figure 11, the cavity is filled by the profile (3), and the recess (8) of the upper top, houses the side flash (11) together with the hook ends (16) of the connector devices that it also serves to rest / deposit and solidify there, some concrete residues that may pass into the recess, in order not to compromise the thermal insulation of the set.
[0086] Numa realização, de acordo com figura 13, o painel (1,5) não Standard com 150mm de espessura serve de exemplo e destina-se apenas a aplicar no lado da cofragem correspondente ao exterior da construção, adaptável ao clima da zona. Por exemplo, em países muito frios ou simplesmente para satisfazer clientes mais exigentes que queiram um isolamento térmico superior. [0086] In one embodiment, according to figure 13, the 150mm thick non-standard panel (1.5) serves as an example and is only intended to be applied on the side of the formwork corresponding to the exterior of the building, adaptable to the climate of the area . For example, in very cold countries or simply to satisfy more demanding customers who want superior thermal insulation.
[0087] É de salientar que neste caso o cliente praticamente irá só pagar a diferença correspondente a quantidade a mais de EPS, pois não altera quase nada a velocidade e custo do fabrico. [0087] It should be noted that in this case the customer will practically only pay the difference corresponding to the amount of more EPS, as it hardly changes the speed and cost of manufacture.
