Tecwool\u00ae F - Laje de abobadilha Cer\u00e2mica e Vigas de madeira<\/h1>

Nas reabilita\u00e7\u00f5es nos deparamos com lajes pouco convencionais. Neste caso, temos uma laje composta por uma camada de compress\u00e3o de bet\u00e3o de 50 mm de espessura, debaixo da qual colocamos um tijolo cer\u00e2mico que se apoia sobre as vigas de madeira de 140 x 140 mm de sec\u00e7\u00e3o.<\/p>\n
Realizou-se o ensaio segundo a norma UNE EN 1365- 2<\/strong>. Colocaram-se termopares sobre a camada de compress\u00e3o e ao longo das vigas de madeira, com o prop\u00f3sito de poder extrapolar os resultados a outras configura\u00e7\u00f5es mais favor\u00e1veis, sempre que elas estivessem em concord\u00e2ncia com as limita\u00e7\u00f5es da norma referida.<\/p>\n
Para mais informa\u00e7\u00e3o no Anexo E do DB SI<\/strong> estabelece-se um m\u00e9todo de c\u00e1lculo que permite determinar a resist\u00eancia dos elementos estruturais de madeira frente \u00e0 a\u00e7\u00e3o representada pela curva normalizada tempo\/temperatura. Fundamentalmente, a resist\u00eancia do fogo vem determinada pelo tamanho das vigas, o grau de exposi\u00e7\u00e3o ao fogo e as cargas suportadas pelas mesmas.<\/p>\n

Aplica\u00e7\u00e3o<\/h2>

Devido \u00e0s caracter\u00edsticas particulares da madeira, a aplica\u00e7\u00e3o de Tecwool\u00ae F<\/strong> nesta solu\u00e7\u00e3o difere-se pontualmente com respeito ao restante de paramentos analisados. A higroscopicidade da madeira faz com que ela absorva ou ceda \u00e1gua do ambiente que a rodeia.<\/p>\n
Para evitar problemas de ader\u00eancia pelas contra\u00e7\u00f5es que sofre a madeira, recobre-se a superf\u00edcie da mesma com uma malha met\u00e1lica fixada ao suporte com grampos ou outro elemento similar, previamente \u00e0 aplica\u00e7\u00e3o do bet\u00e3o Tecwool\u00ae F.<\/strong><\/p>\n
A malha atua como um refor\u00e7o entre o produto e o paramento e atribuindo \u00e0 solu\u00e7\u00e3o uma flexibilidade extra e uma ader\u00eancia ao suporte independentemente das dilata\u00e7\u00f5es da mesma.<\/p>\n
A aplica\u00e7\u00e3o sobre a abobadilha cer\u00e2mica considera-se similar \u00e0 exposta em lajes e paredes de bet\u00e3o. Para evitar desperd\u00edcios de material e para dotar um acabado uniforme e homog\u00eaneo \u00e0 proje\u00e7\u00e3o \u00e9 importante comprovar que n\u00e3o existem buracos na laje.<\/p>\n
