Description

Technical Field

[0001] This utility model belongs to the field of steel beam connection technology, and more specifically, it relates to a vertical connection structure between a steel beam and a steel column. Background Technology

[0002] With the deepening of industrialization, steel-based support systems are constantly developing, and there are more and more high-rise steel structure support systems. The connection strength and stability of steel beams, as well as the construction cycle, are receiving increasing attention. Among them, the structural design of the connection nodes between beams and columns in the vertical or horizontal direction directly affects the stability and support strength of the entire steel structure.

[0003] In existing technologies, clean rooms are often supported by steel structures, which require H-shaped steel columns to be suspended from the bottom of the roof. The traditional connection method is to fully weld the H-shaped steel columns to the steel beams at the roof. Since the overall length of the weld is very long when welding multiple sets of steel columns, the on-site welding takes a long time. In addition, stress and deformation are easily generated at the welds of the roof steel beams, which will affect the stability of the steel beams. Utility Model Content

[0004] The purpose of this utility model is to provide a vertical connection structure between steel beams and steel columns, which aims to solve the technical problems of long time consumption, easy stress and deformation of weld structure and poor stability of traditional beam and column welding structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A vertical connection structure for steel beams and steel columns is provided for connecting horizontal steel beams and vertical steel columns. The extension direction of the horizontal steel beam is defined as a first direction, and the horizontal direction perpendicular to the first direction is defined as a second direction. The vertical connection structure for steel beams and steel columns includes:

[0006] A first mounting plate is fixed to the top of the vertical steel column; both ends of the first mounting plate extend along the second direction past both ends of the horizontal steel beam.

[0007] Two sets of second mounting plates are symmetrically distributed at both ends of the horizontal steel beam along the second direction; one end of each second mounting plate abuts against the horizontal steel beam, and the other end extends along the second direction above the extension end of the first mounting plate;

[0008] In each set, multiple sets of threaded connectors are provided between the extension end of the second mounting plate and the extension end of the first mounting plate.

[0009] In one possible implementation, a set of support members is sandwiched between the extension end of each of the second mounting plates and the extension end of the first mounting plate, and multiple sets of the threaded connectors are placed between the two sets of support members.

[0010] In some embodiments, the height of the support member in the vertical direction is not less than the thickness of the horizontal steel beam sandwiched between the first mounting plate and the second mounting plate.

[0011] For example, the support member is a support shaft extending along the first direction, the support shaft is fixedly connected to the bottom of the second mounting plate, and the bottom of the support shaft abuts against the top surface of the first mounting plate.

[0012] For example, the support member is a hinge shaft extending along the first direction, and the second mounting plate is hinged to the first mounting plate via the hinge shaft.

[0013] For example, the support member is a pad extending along the first direction, the bottom of the pad being fixed to the top of the first mounting plate, and the top abutting against the bottom surface of the second mounting plate.

[0014] In some embodiments, in the second direction, the length by which each of the second mounting plates abuts against the horizontal steel beam is greater than the length by which the second mounting plate extends above the first mounting plate.

[0015] In one possible implementation, the threaded connector includes a connecting bolt and a mounting nut, one end of the connecting bolt extending vertically through the first mounting plate and the second mounting plate and being fixed to the mounting nut.

[0016] In one possible implementation, the bottom of the first mounting plate is provided with multiple sets of first ribs, which are spaced around the vertical steel column and fixedly connected to the side wall of the vertical steel column.

[0017] In some embodiments, each set of second mounting plates has multiple sets of second ribs at its top away from the first mounting plate, and the multiple sets of second ribs are spaced apart along the first direction.

[0018] Compared with the prior art, the solution shown in this application embodiment uses a first mounting plate and two sets of second mounting plates clamped at both ends of a horizontal steel beam, and the extension ends of the first and second mounting plates are fixed by threaded connectors. This clamps the two ends of the horizontal steel beam with the first and second mounting plates, thereby achieving the connection between the horizontal steel beam and the vertical steel column. The connection strength meets the actual needs and has good stability. Furthermore, the first mounting plate and the vertical steel column are pre-assembled, and the connection between the horizontal steel beam and the vertical steel column can be achieved on site simply by fixing the first and second mounting plates with threaded connectors. This can greatly shorten the construction period and improve work efficiency. Attached Figure Description

[0029] Please refer to the following: Figures 1 to 4 The vertical connection structure between the steel beam and the steel column provided by this utility model is described below. The vertical connection structure between the steel beam and the steel column is used to connect a horizontal steel beam 1 and a vertical steel column 2. The extension direction of the horizontal steel beam 1 is defined as the first direction, and the horizontal direction perpendicular to the first direction is defined as the second direction. The vertical connection structure between the steel beam and the steel column includes a first mounting plate 3, two sets of second mounting plates 4, and multiple sets of threaded connectors 5. The first mounting plate 3 is fixed to the top of the vertical steel column 2. Both ends of the first mounting plate 3 extend along the second direction past both ends of the horizontal steel beam 1. The two sets of second mounting plates 4 are symmetrically distributed along the second direction at both ends of the horizontal steel beam 1. One end of each second mounting plate 4 abuts against the horizontal steel beam 1, and the other end extends along the second direction above the extension end of the first mounting plate 3. Multiple sets of threaded connectors 5 pass through the extension end of each set of second mounting plates 4 and the extension end of the first mounting plate 3.

[0030] It should be understood that the horizontal steel beam 1 can be in the form of an H-shaped cross-section or a rectangular plate-like structure; and when the horizontal steel beam 1 is in the form of an H-shaped cross-section, the two second mounting plates 4 abut against the bottom plate of the H-shaped steel beam and are located on both sides of the central web; and the two second mounting plates 4 extend in opposite directions past both ends of the H-shaped steel beam.

[0031] Please see Figure 4 When the horizontal steel beam 1 has a rectangular cross-section, the two second mounting plates 4 abut against the top of the square steel beam, and the two second mounting plates 4 extend in opposite directions past both ends of the square steel beam.

[0032] Optionally, the first mounting plate 3 is fixed to the top of the vertical steel column 2 by welding, and this welding operation can be completed in the factory to reduce the amount of welding work on site.

[0033] The vertical connection structure between the steel beam and the steel column provided by this utility model, compared with the prior art, the solution shown in the embodiment of this application, by clamping the two ends of the horizontal steel beam 1 with the first mounting plate 3 and two sets of second mounting plates 4, and fixing the extension ends of the first mounting plate 3 and the second mounting plate 4 with threaded connectors 5, thereby clamping the two ends of the horizontal steel beam 1 with the first mounting plate 3 and the second mounting plate 4, and thus realizing the connection between the horizontal steel beam 1 and the vertical steel column 2. The connection strength meets the actual needs and has good stability. Moreover, the first mounting plate 3 and the vertical steel column 2 are pre-assembled, and on site, only the first mounting plate 3 and the second mounting plate 4 need to be fixed with threaded connectors 5 to realize the connection between the horizontal steel beam 1 and the vertical steel column 2, which can greatly shorten the construction period and improve work efficiency.

[0034] Please see Figure 1 In some possible embodiments, a set of support members 6 is sandwiched between the extension end of each second mounting plate 4 and the extension end of the first mounting plate 3, and multiple sets of threaded connectors 5 are placed between the two sets of support members 6.

[0035] By setting the support member 6 to support the extended ends of the first mounting plate 3 and the second mounting plate 4, and at the same time preventing the ends of the second mounting plate 4 and the first mounting plate 3 and the horizontal steel beam 1 from falling off, the clamping strength of the first mounting plate 3 and the second mounting plate 4 is guaranteed, and the stability of the connection between the horizontal steel beam 1 and the vertical steel column 2 is improved.

[0036] Please see Figures 2 to 4 In some embodiments, the height of the support member 6 in the vertical direction is not less than the thickness of the horizontal steel beam 1 sandwiched between the first mounting plate 3 and the second mounting plate 4.

[0037] Preferably, the height of the support member 6 in the vertical direction is equal to the thickness of the horizontal steel beam 1 sandwiched between the first mounting plate 3 and the second mounting plate 4; in this case, the clamping effect between the first mounting plate 3 and the second mounting plate 4 is better, which can ensure the stability of the connection between the horizontal steel beam 1 and the vertical steel column 2.

[0038] Please see Figure 2 As a specific embodiment of the aforementioned support member 6, the support member 6 is a support shaft 61 extending along the first direction. The support shaft 61 is fixedly connected to the bottom of the second mounting plate 4, and the bottom of the support shaft 61 abuts against the top surface of the first mounting plate 3.

[0039] Optionally, the support shaft 61 is integrally formed with the second mounting plate 4; or the support shaft 61 is welded to the bottom of the second mounting plate 4. Furthermore, this connection can also be directly fabricated in the factory to reduce the amount of on-site assembly or welding and improve on-site installation efficiency.

[0040] It should be understood that after the first mounting plate 3 and the second mounting plate 4 are fixed by the threaded connector 5, the support shaft 61 can be effectively supported on the outside of the threaded connector 5, thereby pressing the end of the second mounting plate 4 away from the support shaft 61 downward onto the horizontal steel beam 1.

[0041] Please see Figure 2 As another specific embodiment of the support member 6, the support member 6 is a hinge shaft extending along the first direction, and the second mounting plate 4 is hinged to the first mounting plate 3 through the hinge shaft.

[0042] By setting the support 6 as a hinge axis, the second mounting plate 4 can be easily rotated around its hinge axis to achieve a detachable connection between the first mounting plate 3 and the second mounting plate 4. Furthermore, by making the first mounting plate 3 and the second mounting plate 4 appear as a set, the loss of one set of the second mounting plates 4 can be avoided.

[0043] Please see Figure 3 As another specific embodiment of the above-mentioned support member 6, the support member 6 is a pad 62 extending along the first direction. The bottom of the pad 62 is fixed to the top of the first mounting plate 3, and the top abuts against the bottom surface of the second mounting plate 4.

[0044] Optionally, the bottom of the pad 62 is fixed to the bottom of the second mounting plate 4, and the bottom abuts against the top surface of the first mounting plate 3.

[0045] By setting the support member 6 as a plate-like structure such as a pad 62, the structure of the pad 62 can be easily processed, and the contact surface between the bottom of the support member 6 and the first mounting plate 3 / second mounting plate 4 can be increased, thereby reducing stress concentration on the contact surface and avoiding damage to the contact surface.

[0046] Please see Figure 1 In some embodiments, in the second direction, the length of each second mounting plate 4 abutting against the horizontal steel beam 1 is greater than the length of the second mounting plate 4 extending above the first mounting plate 3.

[0047] By making the length of the second mounting plate 4 abutting against the horizontal steel beam 1 greater than the length of the second mounting plate 4 extending onto the first mounting plate 3, the limiting length of the second mounting plate 4 on the horizontal steel beam 1 can be increased, preventing the second mounting plate from detaching from the top horizontal steel beam 1 and enhancing the connection stability of the structure.

[0048] Please see Figure 2 or Figure 3 In some possible embodiments, the threaded connector 5 includes a connecting bolt 51 and a mounting nut 52. One end of the connecting bolt 51 extends vertically through the first mounting plate 3 and the second mounting plate 4 and is screwed and fixed to the mounting nut 52.

[0049] Optionally, the connecting bolt 51 is a high-strength bolt to ensure the connection strength between the first mounting plate 3 and the second mounting plate 4.

[0050] Please see Figure 1 In some possible embodiments, the bottom of the first mounting plate 3 is provided with multiple sets of first ribs 31, which are spaced around the vertical steel column 2 and fixedly connected to the side wall of the vertical steel column 2.

[0051] By setting the first rib 31, the connection strength between the first mounting plate 3 and the vertical steel column 2 can be enhanced, and the support strength of the vertical steel column 2 can be improved.

[0052] Optionally, four sets of first ribs 31 are provided, which are arranged around the four sides of the vertical steel column 2. Further, when the cross-section of the vertical steel column 2 is an H-shaped structure, four sets of first ribs 31 are provided, and the area of ​​the first ribs 31 connected to both sides of the H-shaped steel column is larger than the area connected to both sides of the central web of the H-shaped steel column, so as to specifically enhance the support strength of the steel column.

[0053] Please see Figure 1 In some embodiments, each set of second mounting plates 4 is provided with multiple sets of second ribs 41 at the top away from the first mounting plate 3, and the multiple sets of second ribs 41 are spaced apart along the first direction.

[0054] Optionally, two sets of second ribs 41 are provided; multiple sets of second ribs 41 are used to enhance the connection strength of the second mounting plate 4 and prevent damage to the second mounting plate 4.
