[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 7 As shown, this embodiment of the utility model provides a modular unit connection node for steel structures, including several modular units and connectors for connecting the modular units. Each modular unit includes a modular column 1 and a modular beam 2 fixedly connected to the modular column 1. The connectors include a connector body 4 located at the connection between the modular column 1 and the modular beam 2 for connecting the modular column 1 and the modular beam 2, and a connecting plate 3 located between two adjacent modular units for fixed connection of adjacent connector bodies 4. It should be noted that the connector body 4 needs to be processed together with the modular column 1 and welded to the modular beam 2.

[0025] Furthermore, the connector body 4 includes a first plate 401 that fits against the end face of the module column 1 and a second plate 402 that is parallel to the first plate 401 and is connected to the connecting plate 3. A third plate 403 is connected between the ends of the first plate 401 and the second plate 402. Both the second plate 402 and the connecting plate 3 are provided with a plurality of connecting holes 405. Connecting bolts 5 are inserted into the connecting holes 405 for fixing the connector body 4 and the connecting plate 3 with at least one nut. When the number of connecting bolts 5 meets the load-bearing requirements, the length of the connector body 4 can be increased along the length direction of the module beam 2, thereby increasing the number of connecting bolts 5 accordingly. When adjacent modular units on the left and right need to be connected, the length of the connecting plate 3 can be increased to fix the two adjacent units on the left and right. Preferably, in this embodiment, multiple stiffening ribs 404 are vertically fixedly connected between the first plate 401 and the second plate 402. A haunch plate 6 is also fixedly connected to the inner side of the connection between the modular column 1 and the modular beam 2. The haunch plate 6 increases the rigidity of the connection node. Furthermore, for ease of installation, at least one connection hole 405 is provided with a connecting cone 7 for guiding the second plate 402 and the connecting plate 3 into position. The connecting cone 7 facilitates the hoisting and guiding of the modular unit into position. It should be noted that during installation, the lower modular unit is installed first. After the lower modular unit is installed, the connecting plate 3 is installed, and then the upper modular unit is installed using the connecting cone 7 for guiding the positioning. After the upper modular unit is in position, the connecting bolts 5 are installed, thus completing the connection of the modular units.
