Main column 2 belongs to support stressed component, it is connected with building main structure, and pull beam 3 is arranged between adjacent main column 2, is connected by pull beam 3 transversely, and the overall stressed structure of grating system is formed. Edge column 1 is connected with main column 2, to enable the stable installation of edge column 1, the upper portion and lower portion of main column 2 are provided with upper connecting plate 4 and lower connecting plate 5 respectively, and its shape can be rectangular as shown. A plurality of bolt holes are formed on upper connecting plate 4 and lower connecting plate 5, and the hanging of edge column 1 is realized by fastening bolt 6.

[0035] In one specific embodiment of the present embodiment, the cross section of the side column 1 is provided in a three-section structure, including a front section, a middle section and a rear section. The front section is a closed rectangular cavity, which has the same shape as the grid bar 14 of the grid unit and can change with the outer shape of the grid bar of different specifications, so it can also be considered as part of the grid unit after installation. The middle section is a closed rectangular cavity, and the left and right side walls of the rectangular cavity are provided with pin holes 7, and the spring pins 17 of the grid unit are inserted into the pin holes 7 during installation. The rear section and the middle section form two C-shaped grooves with openings outward, and the openings are provided with opening ribs for buckling with the side buckle plate 8 to seal the C-shaped groove with the side buckle plate 8 to ensure the integrity of the structure. A certain gap is formed between the two C-shaped grooves, which is used for the insertion of the upper connecting plate 4 or the lower connecting plate 5, and the gap is provided with a groove rib for buckling with the end buckle plate 9 to seal the gap with the end buckle plate 9 to ensure the integrity of the structure. Please refer to Figure 5 . At the same time, the center positions of the C-shaped groove, the upper connecting plate 4 and the lower connecting plate 5 are provided with bolt holes, and the fastening bolts 6 and the fastening washers 10 are used to realize fastening connection, so that the side column 1 is fastened and connected with the main column 2. As a preferred embodiment, the surface of the fastening washer 10 in contact with the C-shaped groove is provided with a sawtooth shape to make the connection more reliable and further reduce the possibility of slipping and loosening. Please refer to Figure 6 .

[0036] It should be noted that the bolt holes of the C-shaped groove in the present embodiment are provided in a transverse long circular hole to realize the in-out position adjustment of the side column 1 and the main column 2. Similarly, the bolt holes on the lower connecting plate 5 are provided in a vertical long circular hole to realize the tension bending stress of the side column 1.
