Fireproof and smoke-proof rolling curtain device: support and fixing frame device and its assembly method

Abstract

This invention comprises a preparation step, a preliminary assembly step, a preliminary positioning step, a left and right support component fixing step, an alignment and lowering connection step, and a fine-tuning step. After assembling a fireproof and smoke-proof curtain device and a top frame into one unit, it is moved to a first height position. Then, a left and a right support component are fixed to the ground. The fireproof and smoke-proof curtain device and the top frame are aligned with the left and right support components, and then lowered from the first height to a second height, so that a left and a right lower protrusion are respectively inserted into and fixed to a left and a right upper fixing part, thus fixing the top frame, left support component, and right support component into a single structure. This invention achieves the advantages of being able to be installed on partition walls with low structural strength, relatively quick and convenient installation, and the ability to fine-tune the fixing angle to improve installation accuracy.
