B. prefabricating a cross beam (200), selecting a limiting mechanism (400) according to design rules, pre-burying the limiting mechanism (400) in the cross beam (200), forming a limiting hole (440) at one side of a first limiting part (410) and a second limiting part (420) opposite to a first connecting part (310) and a second connecting part (320) and at a connecting end corresponding to an internal thread sleeve (330), forming a second mounting hole (450) at the top of the first limiting part (410) and the bottom of the second limiting part (420), and forming a positioning cone (421) at the bottom of the second limiting part (420) in a downward protruding mode;
C. prefabricating a connecting plate (600), processing the surface of the connecting plate (600) into a rough surface according to design rules, and arranging connecting holes (610) corresponding to the first mounting holes (340) and the second mounting holes (450) according to the number, the size and the spacing distance of the first mounting holes and the second mounting holes;
D. the method comprises the steps of field installation, after the upright column (100) is fixed, hoisting a cross beam (200) to the position of an L-shaped bracket (300), enabling a positioning cone (421) to be embedded into a positioning groove (321), fixing the L-shaped bracket (300) and the cross beam (200) through a fastening bolt (500), installing a connecting plate (600) at the top and the bottom of the L-shaped bracket (300) and the cross beam (200), connecting the L-shaped bracket (300) and the cross beam (200) in a full dry mode in the installation process, and avoiding support in the beam bottom construction process.
