[0024] Example

[0025] This embodiment provides a steel structure node connection structure, such as Figure 1 and Figure 2 As shown, it includes a main beam 1, a sub-beam 2 and an angle steel connector 3 and a positioning member 4 for connecting the two. The end of the sub-beam 2 is arranged perpendicular to the main beam 1. The angle steel connector 3 is arranged on both sides of the connection between the sub-beam 2 and the main beam 1. One side limb plate is welded to the main beam 1, and the other side limb plate is bolted to the sub-beam 2. The positioning member 4 is arranged below the end of the sub-beam 1 to support the limited sub-beam 2.

[0026] In this embodiment, the angle steel connector 3 can be welded in advance or connected on site, which can be selected according to the working conditions.

[0027] In this embodiment, the positioning member 4 includes a bottom plate 41 and a limit plate 42. The bottom plate 41 is arranged directly below the end of the sub-beam 1. It is L-shaped, with one side plate welded to the main beam 1 and the other side plate firmly bolted to the sub-beam 2. The limit plate 42 is arranged at the other side plate away from the end of the main beam 1.

[0028] In this embodiment, a reinforcing rib 5 is provided below the bottom plate 41 to reinforce the positioning member 4 to prevent the positioning member 4 from being damaged when the sub-beam 2 falls.

[0029] In this embodiment, the spacing between the lower portions of a pair of the limiting plates 42 is the same as the width of the sub-beam 2, so as to limit the sub-beam 2, enable the interface to be accurately docked, and improve installation efficiency.

[0030] In this embodiment, a pair of the limit plates 42 are symmetrically arranged, including a guide plate 421 and a fixed plate 422. The bottom end of the guide plate 421 is connected to the bottom plate 41. A pair of guide plate brackets form a cavity for accommodating the sub-beam 2, and an inclined surface is arranged at the upper end thereof, which is used to guide the sub-beam 2 during its suspension and fall, reduce manual operation, and improve safety. The fixed plate 422 is arranged at the lower part of the guide plate 421 near the end of the main beam 1. When the sub-beam 2 falls, the construction personnel will only use the tower crane to make it fall into the front half of the positioning member 4 first. After the bottom of the sub-beam 2 contacts the bottom plate 41, it moves toward the end of the main beam 1, and accurate positioning is achieved through the fixed plate 422.

[0031] In this embodiment, the distance between the fixing plate 422 and the bottom plate 41 is the same as the thickness of the sub-beam 2, and threaded holes are provided at corresponding positions of the fixing plate 422, the bottom plate 41 and the sub-beam 2 to better fix the sub-beam 2.

[0032] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
