Description
OBJECTO DO INVENTO O presente invento, conforme se explica no enunciado desta memória descritiva, diz .respeito a uma porta corta-fogos que compreende, em princípio, do mesmo modo que outras portas do mesmo tipo, uma folha, que constitui a porta propriamente dita e um aro ajustado no pré-aro A porta tem por finalidade evitar a passagem de fumos de uma dependência para outras, pelo menos durante 90 minutos, conforme o estabelecido pelas normas em vigor, tempo este que é o mínimo que a porta resiste sem se incendiar.OBJECT OF THE INVENTION The present invention, as explained in the specification of this specification, refers to a firebreak door which, in principle, comprises, in the same way as other doors of the same type, a leaf, which constitutes the door itself and a rim fitted in the pre-ring The door is intended to prevent the passage of smoke from one room to another, for at least 90 minutes, as established by the regulations in force, which is the minimum time the door resists without burn
Para tal, a nova porta compõe-se de materiais ignífugos e intumescentes distribuídos vantajosa e estrategicamente, tanto na folha como no aro onde a folha é encaixada.To do this, the new door is composed of flammable and intumescent materials distributed advantageously and strategically, both in the sheet and in the rim where the sheet is fitted.
ANTECEDENTES DO INVENTOBACKGROUND OF THE INVENTION
Actualmente são conhecidas diversas portas corta-fogos, entre as quais importa destacar aquelas cujas folhas compreendem painéis exteriores de material intumescente, de tal modo que, quando há fogo, essas bandas de material intumescente alargam-se fazendo pressão contra o perímetro da porta, assegurando, assim, um fecho praticamente hermético, para evitar principalmente a passagem do fumo entre as dependências separadas pela respectiva porta corta-fogos. Naturalmente, as portas evitarão também a passagem das chamas do fogo de uma dependência para outra, pelo menos durante o tempo regulado pela normativa em vigor.A number of firebreak doors are currently known, among which those whose leaves comprise outer panels of intumescent material are known such that, when there is a fire, these bands of intumescent material widen by pressing against the perimeter of the door, ensuring , thus a substantially hermetic closure, in order to avoid especially the passage of the smoke between the dependencies separated by the respective firewall door. Of course, the doors will also prevent the passage of fire flames from one dependency to another, at least during the time set by the regulations in force.
DESCRIÇÃO DO INVENTO 3 A porta corta-fogos que constitui o objecto do presente invento é determinada a partir de uma folha unida por dobradiças a um aro, no qual se ajusta, em princípio, folgadamente a referida folha, ajustando-se, por sua vez, esse aro a um pré-aro.DESCRIPTION OF THE INVENTION The firebreak gate which forms the object of the present invention is determined from a leaf hingedly attached to a ring, in which the leaf is in principle set loosely, and in turn , this ring to a pre-ring.
Partindo desta premissa, a folha da porta compreende um painel central de material intumescente e dois painéis laterais e exteriores de material ignífugo, estando, por sua vez a referida folha orlada por um aro perimetral de madeira maciça que inclui bandas de material intumescente. 0 aro foi fabricado com um material ignífugo de densidade média e conta com uma banda de material intumescente.Starting from this premise, the door leaf comprises a central panel of intumescent material and two side and outer panels of fire retardant material, in turn said sheet being fringed by a perimetral ring of solid wood including bands of intumescent material. The ring was made of medium density fire retardant material and has a band of intumescent material.
Finalmente, importa salientar que entre o aro e o pré-aro existe uma outra banda de material intumescente, que em conjunto com as outras peças do mesmo material, citadas anteriormente, provocam um efectivo e seguro fecho da folha da porta quando se verificar o fogo, justamente devido ao calor emanado das chamas do fogo.Finally, it should be pointed out that between the ring and the pre-ring there is another band of intumescent material, which together with the other parts of the same material, mentioned above, provoke an effective and secure closing of the door leaf when the fire occurs , precisely because of the heat emanating from the flames of the fire.
Assim, quando o fogo ocorre, o calor das chamas provoca um rápido alargamento das peças de material intumescente, aumentando-lhes o volume e fazendo, portanto, com que a porta pressiona perimetralmente o aro onde se encontra encaixada, verificando-se um fecho hermético que evitará a passagem do fumo e também do fogo de uma dependência para a outra, pelo menos durante um tempo previsto de aproximadamente 90 minutos.Thus, when the fire occurs, the heat of the flames causes a rapid widening of the pieces of intumescent material, increasing their volume and thus causing the door to press perimetrally the ring where it is fitted, checking an hermetic closure which will prevent the passage of smoke and also the fire from one dependency to another, at least for a predicted time of approximately 90 minutes.
De seguida, para ajudar a compreender melhor esta memória descritiva e fazendo parte integrante da mesma, juntam-se desenhos, em que, com carácter ilustrativo e não limitativo, foi representado o objecto do invento.In order to better understand this specification and to form an integral part thereof, there is attached a drawing in which, with illustrative and non-limiting character, the object of the invention has been represented.

DESCRIÇÃO DA FORMA DE REALIZAÇÃO PREFERIDADESCRIPTION OF THE PREFERRED EMBODIMENT
Fazendo referência à numeração adoptada nas figuras, a porta corta-fogos é determinada a partir de uma folha 1 unida com dobradiças a um aro 2, onde se encaixa a folha 1 por meio das ferragens de dobradiças não representadas nas figuras. Pór sua vez, o aro é ajustado sobre um pré-aro exterior 3. A folha 1 da porta compreende um painel central 4 de material intumescente e dois painéis laterais exteriores 5 de material ignífugo que são unidos a ambos os lados do referido painel central 4. Esses três painéis são unidos por meio de um adesivo vinílico reticulável.Referring to the numbering adopted in the figures, the fire door is determined from a sheet 1 hingedly attached to a rim 2, where the sheet 1 is fitted by means of the hinge fittings not shown in the figures. In turn, the ring is fitted over an outer pre-ring 3. The door leaf 1 comprises a central panel 4 of intumescent material and two outer side panels 5 of fire retardant material which are attached to both sides of said central panel 4 These three panels are joined by means of a crosslinkable vinyl adhesive.
Além disso, a folha 1 tem uma moldura perimetral ou cantoneira de madeira maciça 6 que inclui, pelo menos, uma banda de material intumescente, embora no exemplo de realização mostrado nas figuras a citada moldura 6 inclua duas dessas bandas 7.Further, the sheet 1 has a perimetral frame or solid wood frame 6 which includes at least one band of intumescent material, although in the embodiment shown in the figures said frame 6 includes two such bands 7.
Essas bandas 7 de material intumescente encontram-se encaixadas em ranhuras complementares 8 estabelecidas em planos paralelos aos painéis da folha 1 da porta.These bands 7 of intumescent material are engaged in complementary grooves 8 laid out in planes parallel to the panels of the door leaf 1.
Os perfis componentes da cantoneira 6 de madeira maciça encontram-se revestidos e envolvidos por uma fina chapa 9 de madeira da mesma espécie ou tipo que a utilizada na cantoneira 5 0 aro 2 está fabricado com um material de densidade média e ignífugo, incluindo também uma banda 10 de material intumescente encaixada num entalhe complementar 11 de pouca altura preparado para tal. Este entalhe 11. encontra-se situado 5 no lado frontal 12 do aro enfrentado com a moldura 6 da folha 1 da porta.The component profiles of the solid timber frame 6 are coated and encased by a thin sheet 9 of the same type or type of wood as the one used in the angle frame 5 The frame 2 is made of a medium density and fire retardant material, band 10 of intumescent material fitted into a complementary recess 11 of low height arranged therefor. This notch 11 is located 5 on the front side 12 of the rim facing the frame 6 of the door leaf 1.
Por outro lado, entre o aro 2 e o pré-aro 3 existe uma banda de material intumescente 12. 0 aro também se encontra coberto por uma fina chapa de 10 madeira maciça 13 como a citada anteriormente.On the other hand, between the ring 2 and the pre-ring 3 there is a band of intumescent material 12. The ring is also covered by a thin sheet of solid wood 13 as mentioned above.
Com esta disposição descrita, quando se verifica o fogo, o calor das chamas provoca um rápido alargamento da peças de material, aumentando o volume, de modo que a porta pressionará perimetralmente o aro onde se encontra encaixada, verificando-15 se um fecho praticamente hermético que evitará a passagem do fumo, e também do fogo, de umas dependências para outras, pelo menos durante ura tempo previsto de aproximadamente 90 minutos.With this described arrangement, when the fire occurs, the heat of the flames causes a rapid widening of the pieces of material, increasing the volume, so that the door will press perimetrally the ring where it is fitted, verifying if a practically hermetic closure which will prevent the passage of smoke, and also from fire, from one dependency to another, for at least a predicted time of approximately 90 minutes.
Os alojamentos onde se situam as ferragens (dobradiças, fechaduras, etc.) encontram-se revestidas de um material 20 intumescente que também contribuirá, como é evidente, para a hermeticidade da porta quando ocorrer o incêndio. 25The housings where the fittings (hinges, locks, etc.) are located are lined with an intumescent material which will also, of course, contribute to the door seal when the fire occurs. 25
