Abstract

SISTEMA CONSTRUTIVOTRIDIRECIONAL PARA CONSTRUÇçO DE LAJES NERVURADAS,um inovação construtiva no sistema de construção de lajes nervuradas, CARACTERIZADO,principalmente pelo fato da inserção de uma terceira nervura na estruturação da laje.O presente sistema permite reduzir a espessura da laje e aumenta a sua resistência,condições que possibilita vencer vãos maiores utilizando menos concreto,proporcionando redução na deformação da laje,redução dos esforços nas armaduras,por conseguinte,redução no diâmetro do açoe do cust5o da obra,podendo ser utilizado armação protendida similar às de lajes maciças.Ele permite a redução no consumo do concreto desde as fundações e pilares do prédio,pois sua lajes são mais leves e mais resistentes.O processo de construção de lajes nervuradas tridirecionalmente compreende basicamente a utilização de escoras (1),longarinas (2) de cimbramento,fôrmas plásticas convencionais (3), fôrmas plásticas com nervura (4), fôrmas triangularescom nervura (5), fôrmas plásticas triangulares sem nervuras (6) e armaduras, podendo ou não utilizar tablado entre o cimbramento e as fôrmas.
