Title:
PRE-STRETCHING UNITED STRUCTURE OF CONTINOUS MEMBRANE OF MAMBRANE ROOF STRUCTURE, FORMING THEREOF AND STRETCHING METHOD OF CONTINUOUS MEMBRANE OF MEMBRANE ROOF STRUCTURE
Document Type and Number:
Japanese Patent JP2572950
Kind Code:
B2
Abstract:
PURPOSE: To simplify handling, and to shorten the stretching time.
CONSTITUTION: A continuous membrane before stretching is formed in structure having two coil-shaped membrane stacking sections, and two continuous membranes having membrane stacking sections superposed in a coil shape are prepared in a factory, etc., first when the continuous membrane before stretching having such structure is formed. The two continuous membranes are transported up to a field, and each end section of the two continuous membranes is bonded by welding. When the continuous membrane before stretching having such structure is stretched, the continuous membrane before stretching is carried up to the top section of a membrane roof structure 19 formed by beams 21 by using a crane, etc., first. Connecting membrane sections are fixed among the two opposed beams 21. The membrane stacking sections 13a and 15a are spread up to skirts in the opposite directions respectively along the two opposed beams 21.
