The utility model relates to the technical field of steel
structure support assemblies, and discloses a steel
structure support assembly convenient for
butt joint installation, which comprises a bottom
steel frame and a first supporting seat, the top end of the bottom
steel frame is fixedly connected with the first supporting seat, and the two sides of the first supporting seat are fixedly connected with second connecting blocks. A first movable block is movably hinged between the second connecting blocks, and one side of the first movable block is fixedly connected with a first connecting base. According to the steel
structure support assembly convenient to butt-joint and install, by arranging parts such as a bottom
steel frame, during butt-joint installation, a butt-joint rod can be inserted into a butt-joint groove, then a positioning rod is inserted into a first reserved groove, a second connecting base moves downwards according to the
diameter of a round
pipe, at the moment, the butt-joint rod can move in the butt-joint groove in a guiding mode, and the butt-joint rod can move in the butt-joint groove; and then a third locking nut is screwed outside the positioning rod to be fixed, so that
butt joint is accurate and convenient, and the problem that accurate and rapid
butt joint installation between the two sets of steel structure assemblies is not convenient is solved.
