Desarrollo de un procedimiento constructivo más seguro para invernaderos multitúnel

Abstract

This paper reports the development and testing of a new procedure for constructing multi-span greenhouses, based on the assembly of the roof structure at ground level and later raising it to its final position. To compare the proposed and traditional construction procedures, a greenhouse was assembled employing each method to erect one half of the final structure. The same workers erected both halves. The proposed method showed important advantages in terms of the time spent working at height, the number of workers required, the complementary machinery needed, and the overall assembly time, thus reducing the risk of accidents, concluding that fall from height will be reduced 9,2% due to a reduction of working hours at height in 40%.
