[0030] See Figures 1-3 As shown, a prefabricated building beam-column connection node according to this embodiment includes:

[0031] Column 100;

[0032] The beam-column connecting member 200 has a first end fixedly connected to the outer peripheral wall of the column 100 and a second end opposite to the first end. The beam-column connecting member 2100 includes an integrally formed upper flange connecting plate 201, a lower flange connecting plate 203 and a connecting web 202. The upper and lower ends of the connecting web 202 are respectively connected to the upper flange connecting plate 201 and the lower flange connecting plate 203. The first ends of the upper flange connecting plate 201, the lower flange connecting plate 203 and the connecting web 202 are flush. The second end of the upper flange connecting plate 201 is shorter than the second end of the lower flange connecting plate 203. The second end of the connecting web 202 is flush with the second end of the upper flange connecting plate 201.

[0033] The beam 300 is fixedly connected to the second end of the beam-column connecting member 200.

[0034] In this embodiment, a prefabricated building beam-column connection node is provided. The column 100 and the beam 300 are fixedly connected by a beam-column connection member 200. The second end of the upper flange connection plate 201 of the beam-column connection member 200 is shorter than the second end of the lower flange connection plate 203. Thus, when fixing the beam 300 to the beam-column connection member 200, the beam 300 can be suspended onto the beam-column connection member 200 by hoisting equipment. The two ends of the beam 300 overlap and align on the lower flange connection plate 203, and the hoisting equipment can be unhooked. On-site construction personnel can then fix the beam 300 to the beam-column connection member 200, which simplifies the construction process, shortens the construction time, and greatly improves construction efficiency.

[0035] As an optional implementation of this embodiment, the beam 300 described in this embodiment is an I-beam, and the ends of the I-beam that connect to the beam-column connecting member 200 are flush. The beam 300 in this embodiment adopts a common I-beam structure, requiring no special customization and reducing production costs.

[0036] Specifically, the beam 300 in this embodiment includes an integrally formed upper flange plate 301, a lower flange plate 303, and a beam web plate 302. The upper and lower ends of the beam web plate 302 are respectively connected to the upper flange plate 301 and the lower flange plate 303. The ends of the upper flange plate 301, the lower flange plate 303, and the beam web plate 302 that are connected to the beam-column connecting member 200 are flush.

[0037] Meanwhile, when the beam 300 is fixedly connected to the beam-column connecting member 200, in this embodiment, the lower flange plate 303 of the beam 300 overlaps the upper part of the lower flange connecting plate 203 of the beam-column connecting member 200, the end of the beam web 302 is spliced ​​with the second end of the connecting web 202, and the end of the upper flange plate 301 is spliced ​​with the second end of the upper flange connecting plate 201.

[0038] Specifically, in this embodiment, the upper flange plate 301 and the two sides of the upper flange connecting plate 201 are fixedly connected by reinforcing connecting plates 400.

[0039] In this embodiment, reinforcing connecting plates 400 are respectively provided on the upper and lower sides of the upper flange plate 301 and the upper flange connecting plate 201. High-strength bolts 600 pass through the reinforcing connecting plate 400, the upper flange plate 301 and the upper flange connecting plate 201 to achieve a fixed connection.

[0040] In this embodiment, the beam web 302 and the two sides of the connecting web 202 are fixedly connected by web connecting plates 500.

[0041] In this embodiment, web connecting plates 500 are respectively provided on the front and rear sides of the beam web 302 and the connecting web 202. High-strength bolts 600 pass through the web connecting plates 500, the beam web 302, and the connecting web 202 to achieve a fixed connection. In this embodiment, the lower flange plate 303 of the beam 300 and the lower flange connecting plate 203 of the beam-column connecting member 200 are fixedly connected by high-strength bolts 600.

[0042] In this embodiment, the upper flange plate 301 connection adopts a double shear design, and the lower flange plate 303 connection adopts a single shear design. The bearing capacity of the flange connection is designed according to the principle of equal strength.

[0043] As an optional implementation method in this embodiment, see Figure 4 As shown, in this embodiment, the end of the lower flange plate 303 is longer than the end of the upper flange plate 301. The second end of the connecting web 202 is located on one side of the lower flange connecting plate 203 and has a clearance groove 204 for insertion of the end of the lower flange plate 303. Thus, when the beam 300 and the beam-column connecting member 200 are fixedly connected, their mutual embedding enhances the reliability of the fixed connection.

[0044] Furthermore, during on-site construction, the beam 300 is suspended to one side of the beam-column connection member 200 using hoisting equipment. The beam 300 is then moved horizontally toward the beam-column connection member 200 in a direction perpendicular to the connecting web 202 until the lower flange plate 303 completely overlaps the lower flange connecting plate 203. During this horizontal movement of the beam 300 toward the beam-column connection member 200, the end of the lower flange plate 303 inserts into the clearance groove 204 of the connecting web 202, achieving an embedded connection. Therefore, the prefabricated building beam-column connection node of this embodiment features a simple and reliable assembly construction method.

[0045] Furthermore, in this embodiment, the lower flange plate 303 has an extension 304 at its end. The extension 303 is inserted into the clearance groove 204. The two sides of the connecting web plate 202 are fixedly connected to the extension 304 of the lower flange plate 303 by angle steel. The angle steel also connects the extension 304 of the lower flange plate 303 and the lower flange connecting plate 203.

[0046] Meanwhile, in this embodiment, the length of the extension 304 of the lower flange plate 303 is equal to the length of the clearance groove 204. In this way, while realizing the embedded connection, it does not affect the alignment and splicing of the end of the beam web plate 302 with the second end of the connecting web plate 202, and the alignment and splicing of the end of the upper flange plate 301 with the second end of the upper flange connecting plate 201.

[0047] In this embodiment, the column 100 is a steel pipe column, and the first end of the beam-column connecting member 200 is welded and fixed to the outer peripheral wall of the steel pipe column.

[0048] Alternatively, the column 100 may be a steel-concrete composite column, and the first end of the beam-column connecting member 200 may be embedded in the steel-concrete composite column.

[0049] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
