[0021] The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different parts. The words "include" or "comprise" and similar words mean that the elements before the word include the elements listed after the word, and do not exclude the possibility of including other elements. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] like Figures 1 to 3 As shown, the assembled U-shaped light steel keel node includes a first keel 1 and a second keel 2. A screw connector 3 is clamped inside the first keel 1, and a screw 4 is assembled on the top of the screw connector 3. The upper end of the screw 4 has an expansion component 41. A vertical connector 5 clamped inside the first keel 1 is arranged inside the screw connector 3. The vertical connector 5 has an outer connecting plate 55. The outer connecting plate 55 is symmetrically provided with a plug-in plate 56 matching the end of the second keel 2. The second keel 2 is plugged on the outer side of the plug-in plate 56. In this embodiment, In the embodiment, the second keel 2 is inserted into the outer side of the plug-in plate 56 of the vertical connector 5, and the second keel 2 is connected to the first keel 1 through the vertical connector 5. The vertical connection between the first keel 1 and the second keel 2 is realized by assembly methods such as insertion and clamping, which simplifies the installation process and improves the convenience and efficiency of installation. The vertical connector 5 is limited on both sides by the screw connector 3 to further improve the connection stability between the second keel 2 and the first keel 1. The expansion component 41 has the same structure as the expansion bolt.

[0023] In some embodiments, the first keel 1 has inner buckle grooves 11 on both sides of the top, the screw connector 3 has a first top plate 32, and the first side plates 31 are symmetrically arranged on both sides of the bottom of the first top plate 32. The bottom end of the first side plate 31 has a first insertion end 35, and the ends of the first insertion end 35 are fixedly provided with first clamping handles 34 matching the inner buckle groove 11 on both sides; during installation, the first insertion end 35 is inserted into the interior of the first keel 1, and the first clamping handle 34 is clamped into the interior of the inner buckle groove 11 to achieve quick connection between the screw connector 3 and the first keel 1.

[0024] In some embodiments, the vertical connecting member 5 has a second top plate 54 that matches the distance between the two first side panels 31, and the second side panel 51 is symmetrically arranged at the bottom of the second top plate 54.
