METHOD FOR ASSEMBLAGE OF METAL TOWER-MAST CONSTRUCTIONS

摘要

Method for assemblage of metal tower-mast structures made of separate structural elements through growing up at which mounting is carried out by method of assembling elements from down upwards with following connection and installation of upper, and then following intermediate elements till end installation of those in designed position. First one constructs mounting-support frame as truncated pyramid. After that one mounts in its middle not less than one working site that is fixed in frame without possibility of motion. After that following connections and lift of elements are made from working site. At that one centers and holds in vertical position elements that are installed in sequence and connected to each other, in support-centering ledges that are equipped on working site and upper cross section of the frame.
