Construção de Alvenaria de Bloco 

Estrutural


Os blocos
estruturais são blocos de concreto pré-moldados, fabricados com cimento, areia
e pedrisco. São utilizados nas fiadas intermediárias da fundação com a parede,
como também, em todas as fiadas de uma parede. 

Sobre uma
fundação em sapata corrida, molha-se a sua superfície, polvilha-se com cimento
e estende-se a linha de marcação do eixo das paredes que se encontra marcado no
gabarito. Assenta-se, em cada extremidade, um bloco estrutural com argamassa de
cimento e areia no traço de 1:5. No bloco deve ser marcado seu eixo para que
coincida a marcação do eixo do bloco com a ponta do prumo de centro que sairá
da linha de eixo da parede. 

Detalhe
da Prumada de Centro da Alvenaria de Bloco Estrutural 

Com o
bloco na direção do eixo das paredes, procedesse a operação de prumada da face
interna e do nivelamento conforme indicado na figura ao lado:

Estrutural 

Assentados
os blocos das extremidades (cabeceira) , fixam-se duas linhas (uma em cima
outra em baixo da face aprumada) e os distorce (encosta-os totalmente nas
linhas). Completa-se a fiada assentandose os demais blocos estruturais
colocando-se a argamassa da junta horizontal na área em que serão assentados os
blocos, posicionandose os mesmos através da operação de alinhamento.
