[0045] The following is combined with Figure 1-9 This application is described in further detail.

[0046] The embodiments of the present application disclose a beam-column connection node structure and a construction method thereof.

[0047] Reference Figure 1 The beam-column connection node structure includes a crossbeam 1 and a column 2. A connecting seat 3 is sleeved on the outside of the column 2. A support seat 4 is connected between the lower side of the connecting seat 3 and the column 2. A pressure seat 5 is provided on the upper side of the connecting seat 3. The end of the crossbeam 1 close to the column 2 is connected between the pressure seat 5 and the connecting seat 3.

[0048] Reference Figure 1 、 Figure 2 The column 2 is a square tube with a square cross section, so that the cross beam 1 can be connected to any of the four sides of the column 2. The cross beam 1 includes two parallel flange plates 11, and a web plate 12 is fixedly connected between the two flange plates 11, so that the vertical cross section of the cross beam 1 is I-shaped.

[0049] Reference Figure 2 The connecting base 3 includes a positioning tube 31 that is sleeved onto the outer side of the column 2. The positioning tube 31 has a square cross-section. A connecting plate 32 is fixedly connected to the outer side of the lower end of the positioning tube 31. The connecting plate 32 is annular, and the lower flange plate 11 abuts the upper side of the connecting plate 32. Ribs 33 are fixedly connected to the four corners of the outer side of the positioning tube 31. The lower ends of the ribs 33 are fixedly connected to the connecting plate 32, which enhances the structural strength between the positioning tube 31 and the connecting plate 32. The ribs 33, the crossbeam 1, and the upper end of the positioning tube 31 are flush.

[0050] Reference Figure 2 、 Figure 3 , four support seats 4 are arranged at circumferential intervals around the column 2, and the four support seats 4 are respectively attached to the four outer sides of the column 2. The support seat 4 includes a first support plate 41 and a second support plate 42 that are perpendicular to each other. One end of the first support plate 41 and one end of the second support plate 42 are fixedly connected, so that the first support plate 41 and the second support plate 42 form an L-shaped plate. A first plug rod 43 is fixedly connected to the side of the first support plate 41 facing away from the second support plate 42, and a second plug rod 44 is fixedly connected to the side of the second support plate 42 facing away from the first support plate 41. In the embodiment of the present application, two first plug rods 43 are symmetrically arranged about the center line of the first support plate 41, and one second plug rod 44 is provided. In other embodiments, the number of first plug rods 43 can also be four, six or more.

[0051] Reference Figure 2 、 Figure 3The column 2 is provided with a first insertion hole 21 for inserting the first insertion rod 43 and a second insertion hole 22 for inserting the second insertion rod 44. The connecting plate 32 is provided with a first connection hole 321 for inserting the first insertion rod 43 and a second connection hole 322 for inserting the second insertion rod 44. The flange plate 11 is provided with positioning holes 111 on both sides for inserting the first insertion rod 43. The middle part of the flange plate 11 and the web plate 12 are provided with hinge holes 121 for inserting the second insertion rod 44.

[0052] When the first rod 43 is inserted into the positioning hole 111, the crossbeam 1 is fixed relative to the column 2; when the second rod 44 is inserted into the hinge hole 121, the crossbeam 1 can rotate horizontally relative to the column 2. It can be seen that the support base 4 can adopt different installation methods to make the beam-column node a rigid connection or a hinged connection.

[0053] Specifically, when a rigid connection is required between the beam and column, the second support plate 42 is placed against the outer side of the column 2, the second rod 44 is inserted into the second insertion hole 22, the first support plate 41 is placed against the connecting plate 32, the first rod 43 is passed through the first connecting hole 321 and inserted into the positioning hole 111. When a hinged connection is required between the beam and column, the first support plate 41 is placed against the outer side of the column 2, the first rod 43 is inserted into the first insertion hole 21, the second support plate 42 is placed against the connecting plate 32, the second rod 44 is passed through the second connecting hole 322 and inserted into the hinge hole 121.

[0054] Reference Figure 3 、 Figure 4 To enhance the connection reliability of the first insertion rod 43, a slot 431 is provided on the outer wall of the end of the first insertion rod 43 away from the first support plate 41. A slider 432 is positioned within the slot 431. The slider 432 slides along the slot 431, protruding relative to the outer surface of the first insertion rod 43. When the slider 432 is positioned above the flange 11 on the inner or lower side of the column 2, it acts as a hook, enhancing the tightness of the connection between the support base 4 and the column 2 or support base 4.

[0055] Reference Figure 3 、 Figure 4A push-out spring 433 is fixedly connected between the slider 432 and the inner bottom wall of the slot 431, applying a thrust to the slider 432. A retractable bar 434 is slidably connected to the first insertion rod 43 along its axial direction. One end of the retractable bar 434 extends into the slot 431, and the other end extends through the first support plate 41. The first support plate 41 is provided with a through-hole 411 for the retractable bar 434 to pass through. A pressing handle 435 is fixedly connected to the end of the retractable bar 434 that passes through the through-hole 411. An extrusion slope 4341 is provided on the end of the retractable bar 434 that is distal to the pressing handle 435 and proximal to the push-out spring 433. A through-hole 4321 is provided through the slider 432, through which the retractable bar 434 passes. The inner wall of the through-hole 4321 is provided with a pressure slope 4322 that cooperates with the extrusion slope 4341. The distance between the slider 432 and the first support plate 41 is equal to the sum of the thicknesses of the connecting plate 32 and one flange plate 11.

[0056] Under normal conditions, the slider 432 extends from the first insertion rod 43 under the action of the push-out spring 433, acting as a barb. To remove the support base 4, the pressing handle 435 is pressed, causing the retracting bar 434 to slide closer to the slider 432. The extruding inclined surface 4341 exerts a force on the compressed inclined surface 4322, causing the slider 432 to retract into the sliding groove 431.

[0057] Reference Figure 5 Limit rods 34, threaded onto the upper and lower ends of the ribs 33 and facing the flanges 11, are positioned horizontally. When the crossbeam 1 rotates until the flanges 11 abut the limit rods 34, further rotation is impossible. By turning the limit rods 34 and adjusting the distance between them and the flanges 11, the range of crossbeam 1's rotation can be adjusted.

[0058] Reference Figure 2 、 Figure 6 There is a gap between the beam 1 and the positioning tube 31, and the flange plate 11 is provided with rounded corners 112 on both sides of one end close to the column 2 to facilitate the rotation of the beam 1.

[0059] Reference Figure 2 、 Figure 7 Thickening rings are fixedly connected to the inner side of the column 2 at the first and second insertion holes 21, 22. Therefore, the thickness of the column 2 at the first and second insertion holes 21, 22 is increased, and the thickness at this location is equal to the sum of the thicknesses of the connecting plate 32 and one flange plate 11. Therefore, in both states of the support base 4, the slider 432 can function as a barb.

[0060] Reference Figure 5 、 Figure 8The pressure seat 5 includes a pressure ring 53 and four fixing plates 54 fixedly connected to the inner side of the pressure ring 53. The four fixing plates 54 are respectively attached to the four outer side surfaces of the column 2, and the pressure ring 53 abuts the upper end surface of the flange plate 11 on the upper side. A hinge rod 52 for inserting into the hinge hole 121 is fixedly connected to the side of the pressure ring 53 close to the fixing plate 54, and two positioning rods 51 for inserting into the positioning holes 111 are fixedly connected to the other side. A slot 311 for inserting the fixing plate 54 is provided on the inner side of the connecting seat 3. When the fixing plate 54 is located at the lower side of the pressure ring 53 and inserted into the slot 311, the hinge rod 52 is inserted into the hinge hole 121; when the fixing plate 54 is located at the upper side of the pressure ring 53, the positioning rod 51 passes through the positioning hole 111.

[0061] Reference Figure 8 、 Figure 9 The outer edge of the fixing plate 54, near the column 2, is provided with a welding chamfer 541 to increase the welding area. A positioning nut 6 is threadedly connected to the end of the positioning rod 51 away from the pressure seat 5. When the beam-column joint is rigidly connected, the positioning rod 51 is passed through the positioning hole 111, the positioning nut 6 is tightened until it abuts the lower end surface of the upper flange plate 11, and the fixing plate 54 is welded to the column 2, which significantly improves the rigid structural strength.

[0062] A construction method for a beam-column connection node structure comprises the following steps:

[0063] Rigid connection of beams and columns: first, move the four support seats 4 close to the column 2, so that the second support plate 42 fits the outer side of the column 2, and insert the second insertion rod 44 into the second insertion hole 22, then sleeve the connecting seat 3 from top to bottom on the outside of the column 2, so that the first support plate 41 fits the connecting plate 32, and pass the first insertion rod 43 through the first connecting hole 321, then place the beam 1 on the connecting seat 3, so that the first insertion rod 43 is inserted into the positioning hole 111, and finally sleeve the pressure ring 53 from top to bottom on the outside of the column 2, so that the positioning rod 51 is inserted into the positioning hole 111, tighten the positioning nut 6 and weld the fixing plate 54 to the column 2 along the welding chamfer 541.

[0064] Beam-column hinged connection: first move the four support seats 4 close to the column 2, so that the first support plate 41 fits the outer side of the column 2, and the first plug rod 43 is inserted into the first plug hole 21, and then the connecting seat 3 is sleeved on the outside of the column 2 from top to bottom, so that the second support plate 42 fits the connecting plate 32, and the second plug rod 44 passes through the second connecting hole 322, and then place the beam 1 on the connecting seat 3, so that the second plug rod 44 is inserted into the hinge hole 121, and finally the pressure ring 53 is sleeved on the outside of the column 2 from top to bottom, so that the fixing plate 54 is stuck in the slot 311, and the hinge rod 52 is inserted into the hinge hole 121.

[0065] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
