ABSTRACT:
A built-up post for use in a building is disclosed. It includes: (a) an upper post resembling a long column, the upper post having a first end to be fixedly connected to a steel girder or a ceiling of a building, and a second end having a longitudinal hole, the longitudinal hole having an inner wall with an internal thread; (b) a lower post resembling a long column, one end to be fixedly connected to a steel girder or a floor of a building, the other end having a longitudinal hole, the inner wall of the longitudinal hole having an internal thread; and (c) an intermediate post resembling a long column, each end thereof having a long thread for screwing into the longitudinal holes of the upper and lower posts. The upper post, intermediate post and lower post are joined in alignment with each other, with the long threads of the intermediate post being screwed into the longitudinal holes of the upper and lower posts, respectively. The long thread on one end of the intermediate post is a right-handed thread, and the long thread on the other end is a left-handed thread, such that turning the intermediate post enables the upper and lower posts to produce a longitudinal movement relative to each other.
