[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] like Figure 1 and Figure 2 As shown, a modular steel structure connection node includes: a base column 20, which is a rectangular column and is a conventional steel column. This is existing technology and will not be described in detail here.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the connection structure is set on the top of the base column 20 to connect the base column 20 with other base columns 20. The connection structure includes: sleeve 30, frame 31, sleeve frame 33, mounting plate 40 and flip plate 41. The sleeve 30 is fitted onto the top of the base column 20. The frame 31 is fixedly connected to the edge of the sleeve 30. The sleeve frame 33 is fitted onto the wall of the sleeve 30. The mounting plate 40 is symmetrically fixedly connected to the wall of the sleeve frame 33. The flip plate 41 is symmetrically fixedly connected to the two side walls of the mounting plate 40.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the sleeve 30 is a hollow rectangle with an open bottom, and the frame 31 is an L-shaped block. Each edge of the sleeve 30 has the same frame 31, and the inner corners of the frame 31 can fit against the edges of the sleeve 30. The sleeve frame 33 is a rectangular frame, and its bottom can contact the top of the frame 31. Threaded grooves are formed on the four sides of the sleeve frame 33. The sleeve 30 also has the same threaded grooves on its wall at the same positions as those on the sleeve frame 33. The mounting plate 40 is a rectangular plate, and the flip plate 41 is a rectangular plate. The connection between the flip plate 41 and the mounting plate 40... The structure includes an arc-shaped groove, a connecting structure, a bottom block 34, a clamping plate 35, and an outer support plate 42. The bottom block 34 is fixedly connected to the bottom of each mounting plate 40. The clamping plate 35 is symmetrically fixedly connected to both sides of the bottom of the frame 33. The outer support plate 42 is fixedly connected to the bottom of each flip plate 41. The bottom block 34 is a right-angled triangular block and can fit the spacing of each adjacent frame 31. The clamping plate 35 is a rectangular plate and can also fit the spacing of adjacent frame 31. The outer support plate 42 is a right-angled trapezoidal plate with the inclined surface of the outer support plate 42 facing outward.

[0029] In practical use, first, the sleeve 30 is fitted onto the top of the base column 20, and then the sleeve frame 33 is fitted onto the top of the frame 31. As the sleeve frame 33 is fitted, it can drive the clamping plate 35 and the bottom block 34 to be clamped in the corresponding spacing of the adjacent frame 31. After the sleeve frame 33 is clamped onto the wall of the sleeve 30, the high-strength bolts are screwed into the overlapping threaded grooves. Then, the end of the steel structure to be connected is placed horizontally on the top of the mounting plate 40, and then the corresponding two side flaps 41 are turned upwards. As the flaps 41 are turned from the horizontal position to the vertical position, Wrap the two ends of the steel structure, and then the flip plate 41 and the steel structure can be connected by welding or bolts. When the mounting plate 40 is folded, it can drive the outer support plate 42 to switch to a vertical state at the same time. At this time, the outer support plate 42 will be vertical between the symmetrical limiting blocks 32, and the wall surface of the outer support plate 42 will be stuck in the opening of the limiting block 32. The wall surface of the outer support plate 42 will abut against the opening of the limiting block 32. When the flip plate 41 is folded, it will also drive the top edge 43 to move synchronously and make the inner corner of the top edge 43 fit against the edge of the top of the sleeve 30.

[0030] In summary, by setting up a connection structure, the steel structure and the base column 20 can be quickly connected. After assembly, this solution can achieve high compressive strength through the outer support plate 42, bottom block 34, limiting block 32, clamping plate 35 and top edge 43.

[0031] like Figure 3As shown, the wall surface of the mounting plate 40 is provided with a limiting structure, which includes a top edge 43 and a limiting block 32. The top edge 43 is fixedly connected to the wall surface of the mounting plate 40 facing the opposite mounting plate 40. The limiting block 32 is fixedly connected to the side wall surface of each frame 31. The top edge 43 is a rod with an L-shaped cross section. The inner corner of the top edge 43 can contact and fit with the top edge of the sleeve 30. The limiting block 32 is a semi-concave block. The opening of the limiting block 32 can contact the side wall surface of the folded outer support plate 42.

[0032] In practical use, when the mounting plate 40 is folded, it can drive the outer support plate 42 to switch to a vertical state simultaneously. At this time, the outer support plate 42 will be vertical between the symmetrical limiting blocks 32, the wall surface of the outer support plate 42 will be stuck in the opening of the limiting block 32, and the wall surface of the outer support plate 42 will abut against the opening of the limiting block 32. When the flip plate 41 is folded, it will also drive the top edge 43 to move synchronously and make the inner corner of the top edge 43 fit against the edge of the top of the sleeve 30.

[0033] In summary, by setting a limiting structure, the outer support plate 42 can be prevented from deforming by restricting its position. Furthermore, the degree of folding of the flap 41 can be determined by observing the overlap between the top edge 43 and the sleeve 30.

[0034] Working principle: First, sleeve 30 is fitted onto the top of base column 20, and then frame 33 is fitted onto the top of frame 31. As frame 33 is fitted, it can drive clamping plate 35 and bottom block 34 to be clamped in the corresponding spacing of adjacent frame 31. After frame 33 is clamped onto the wall of sleeve 30, high-strength bolts are screwed into the overlapping threaded grooves. Then, the end of the steel structure to be connected is placed horizontally on the top of mounting plate 40, and then the corresponding two side flaps 41 are flipped upwards. As flaps 41 are flipped from the horizontal position to the vertical position, they will wrap around the two ends of the steel structure. At this time, flaps 41 and steel structure can be connected by welding or bolts.

[0035] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
