Description

Technical Field

[0001] The invention relates to the field of steel support connection, in particular to a steel support connection node structure and an installation method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Steel structure frames are usually used in multi-story and high-rise buildings. Steel structure frames have the characteristics of high structural stability. In order to enhance the stability of steel structure frames, diagonal supports are usually set between columns and beams. Most of the diagonal supports are connected to columns or beams by welding; however, in industrial buildings, such as chemical production environments, there are explosion-proof requirements. In addition, some dust removal equipment has electromagnetic interference. Because sparks are generated during welding, welding operations cannot be performed during the construction of such industrial buildings. Even if welding can be performed, the welding quality cannot be guaranteed, affecting the service life of the entire building system.

[0004] In order to achieve a non-welded connection, Chinese patent application CN202310094160.6 discloses an assembled beam-column node with an oblique support, which is provided with a grooved connecting plate, a vertical support plate and a horizontal support plate, and finally connected with bolts. Although it is connected by bolts, it has the following problems:

[0005] The beams and columns are still connected by welding;

[0006] The connection structure between the diagonal support and the beam and column is relatively complicated. It is necessary to first connect the diagonal support and the node plate, and then connect the node plate to the column and the beam respectively. It is also necessary to connect the horizontal connection plate and the vertical connection plate to the diagonal support, column or beam respectively, which makes the overall installation speed slow;

[0007] The ends of the oblique supports are connected to the node plates by machining grooves and other structures, which places high demands on the machining of the ends of the oblique supports;

[0008] The inventors also found that in other solutions, the cross beams and columns are also connected by bolts, but usually a connecting plate protruding from the cross beam or column is provided at the connection between the cross beam or column, so that a gap exists between the column and the cross beam. Summary of the invention

[0009] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a steel support connection node structure, which has a simple and reasonable structure, is convenient and quick to install and disassemble, and ensures the supporting strength of the overall structure.

[0010] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0015] In the steel support connection node structure as described above, the outer side surface of the connecting member is arranged flush with the side edge of the supporting member where it is located, so as to position the setting of the connecting member and facilitate the connection between the connecting member and the supporting member.

[0016] A steel support connection node structure as described above, wherein one side of the connection member is welded and connected to the support member in advance;

[0017] Alternatively, one side of the connecting member is bolted to the supporting member, and the bolts connect two connecting members arranged at the same position of the supporting member, so that the supporting member can be securely connected to the connecting members on both sides thereof by passing the bolts once.

[0018] In a steel support connection node structure as described above, the support member is fixedly provided with a third end plate, the third end plate and the second end plate are arranged at an angle, the third end plate is arranged perpendicular to the support member, the third end plate is inclined relative to the side of the support member, and one end of the oblique support is welded and connected to the third end plate in advance or bolted on site.

[0019] A steel support connection node structure as described above, wherein the connection member is an angle steel, and the support member is a support plate;

[0020] The cross section of the oblique support is rectangular or circular.

[0021] In the steel support connection node structure as described above, the length of the support member along the length direction of the beam is 1 / 15-1 / 12 of the length of the beam, and the height of the support member along the height direction of the column is 1 / 15-1 / 12 of the height of the column.

Even if welding is required, it can be carried out in advance in the prefabrication factory, and the connecting member is welded to the supporting member or the supporting member is welded to the oblique support. Of course, the supporting member and the oblique support can also be bolted on site, so that no welding is generated on site, thereby ensuring the overall quick connection, realizing on-site non-welding operation, and ensuring the safety of the operation. Moreover, the oblique support is arranged on the upper and lower sides of the connection between the column and the beam, which is conducive to ensuring the overall seismic performance.

[0030] 2) In the present invention, the connection between the oblique support and the column and the beam can be achieved through the cooperation of the support member and the connecting member. The structural arrangement of the support member and the connecting member is reasonable, and the overall structure is simple. The support member is provided with a notch to abut against the second end plate. The overall support member is used as an intermediate force-bearing member without other complicated components, so that the oblique support and the beam and the column can be stably connected, which is convenient for the overall rapid installation; and the connecting member can be used to achieve a stable connection between the support member and the beam or column to ensure the connection strength at the node structure.

[0046] The notch of the support member is L-shaped, and the height of the notch is the same as the height of the second end plate above the surface of the beam.

[0047] In order to ensure a reliable connection between the column 1 and the beam 6, the first end plate 8 is arranged flush with the side of the column 1; in this embodiment, the transverse cross-section of the column 1 is an I-shaped, and the side of the column 1 facing the beam 6 is a plane, and the side of the column 1 facing the beam 6 is widened to form the first end plate 8, and the first end plate 8 and the second end plate 7 are both provided with openings, and the bolts 2, such as high-strength bolts, are passed through the corresponding openings of the first end plate 8 and the second end plate 7 and then locked by nuts;

Specifically, the second end plate 7 is provided with a groove that is engaged with the end of the crossbeam 6. If the longitudinal cross-section of the crossbeam 6 is an I-shape, the second end plate 7 is provided with an I-shaped groove so that the groove of the second end plate 7 is engaged with the end face of the crossbeam 6, thereby making the second end plate 7 flush with the end face of the crossbeam 6.

[0049] It can be understood that connecting members 3 are provided on both opposite sides of the support member 5, and are connected to the columns 1 or beams 6 from both sides of the support member 5, respectively, to ensure the supporting strength of the connection between the support member 5 and the columns 1 or beams 6, and correspondingly ensure the supporting strength of the entire node structure.

[0050] In this embodiment, the support member 5 is a support plate, which is a rectangular support plate. The support member stands between the cross beam and the column. One side of the support member 5 is in contact with the surface of the cross beam 6, and the other side is provided with a notch to be in contact with the second end plate 7. Moreover, the side of the support member 5 provided with the notch is in contact with the side of the column 1.

[0051] Specifically, the column 1 is a steel column 1, the beam 6 is a steel beam 6, the connecting member 3 is an angle steel, the length of the connecting member 3 is smaller than the height of the supporting member 5, and also smaller than the length of the supporting member 5, and the outer side surface of the connecting member 3 is flush with the side of the supporting member 5 where it is located, so as to position the setting of the connecting member 3 and facilitate the connection between the connecting member 3 and the supporting member 5.

[0052] In this embodiment, one side of the connecting member 3 is welded to the supporting member 5 in advance, so that only the other side of the connecting member 3 needs to be connected to the column 1 or the crossbeam 6 on site; in this way, at least two openings are respectively provided at the positions where the crossbeam 6 and the column 1 are connected to the corresponding connecting member 3, and the bolt 2 is tightened by a nut after passing through the openings of the connecting member 3 and the column 1 or the crossbeam 6.

When the oblique support 4 is a circular rod, the oblique support 4 uses the third end plate 10 to achieve connection with the support member 5, which can be welded in advance or connected on site by bolts 2. When the oblique support 4 is a rectangular rod, a bottom side plate is set on the bottom side of the rectangular rod, and the width of the bottom side plate is greater than the width of the bottom side surface. The bottom side plate and the support member 5 are fastened together by bolts 2 and nuts, and the end side of the rectangular rod is connected to the third end plate 10 by bolts 2 on site.

[0056] It can be understood that the oblique support 4 is located on the diagonal of the quadrilateral structure composed of multiple columns 1 and beams 6; the support member 5 is arranged along the center line of the beam 6 and the column 1.

[0057] In this embodiment, the length of the support member 5 along the length direction of the beam 6 is 1 / 15-1 / 12 of the length of the beam 6, and the height of the support member 5 along the height direction of the column 1 is 1 / 15-1 / 12 of the height of the column 1. By limiting the length and height of the support member 5, not only the stable connection between the diagonal support 4 and the beam 6 and the column 1 is guaranteed, but also the material of the support member 5 can be saved while ensuring the strength of the node structure.

Support members 5 are respectively arranged on the upper and lower sides of the connection between the column 1 and the beam 6, and the other side of the connecting member 3 is connected to the column 1 or the beam 6 by bolts 2, thereby forming a connecting node structure.

[0061] Embodiment 2

[0062] The difference between this embodiment and the first embodiment is that:

[0063] refer to Figure 3 and Figure 4 As shown, one side of the connecting member 3 is connected to the supporting member 5 by a bolt 2, and the bolt 2 connects the two connecting members 3 arranged at the same position of the supporting member 5. Since the connecting members 3 are respectively arranged at the same position on the two oppositely arranged sides of the supporting member 5, the bolt 2 passes through the connecting member 3 on one side, the supporting member 5 and the connecting member 3 on the other side at one time and is locked by a nut.
