For example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood in combination with the specific circumstances.

[0053] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0054] This embodiment relates to a steel structure assembly connector, which includes a base 1, an upper top plate 2 and a lower top plate 3 disposed on the base 1, and a driving assembly 4. The driving assembly 4 includes a driving component 401 and inserts 402 slidably connected to the driving component 401. The driving component 401 is rotated to move the upper top plate 2 and the lower top plate 3 vertically, causing them to abut against the inner cavity of the steel structure 7. Simultaneously, a locking plate 5 is screwed onto the base 1 and is disposed on the outer side of the steel structure 7. The locking plate 5 has socket portions 501 on both sides, and two inserts 402 are respectively inserted into the socket portions 501. The driving component 401 is rotated to rotate the locking plate 5, locking it to the outer side of the steel structure 7.

[0055] In this embodiment, the steel structure assembly connector places two steel structure pieces (7 pieces) onto the base 1. By driving the drive component 401 to rotate, the upper top plate 2 and lower top plate 3 respectively abut against the opposing inner cavities of the steel structure pieces 7, thus connecting the two steel structure pieces 7 via the base 1. Due to the screw-on locking plate 5, two inserts 402 are respectively inserted into the socket 501. Driving the drive component 401 to rotate again causes the locking plate 5 to rotate relative to the base 1 and lock onto the outside of the steel structure pieces 7. The upper top plate 2 and lower top plate 3 on the base 1 position and tighten the steel structure pieces 7 from the inside, first positioning the steel structure pieces 7, and then, through the combined action of the locking plate 5 and the base 1, fixing the steel structure pieces 7 to the connector as a whole, ensuring the overall stability and strength of the assembled steel structure pieces 7.

[0056] Furthermore, in this embodiment, the steel structure assembly connectors are prefabricated and assembled in the factory. On-site, the steel structure 7 only needs to be inserted into the connectors. This arrangement facilitates assembly, eliminating the need to support the steel structure 7 and tighten the bolts one by one. This reduces the number of screws, nuts, and other parts used in on-site assembly, thus lowering the difficulty of on-site assembly.

[0057] Based on the above overall introduction, this embodiment provides an exemplary structure of the steel structure assembly connector, such as... Figures 1 to 5 As shown, the steel structure 7 in this embodiment is set up with a rectangular tube as an example. In other embodiments, steel structures 7 such as I-beams, H-beams, and angle steel can also be used for connection. When the above-mentioned steel structure 7 is used, the structure can be adapted to different shapes, which will not be described in detail here.

[0058] As a preferred embodiment, such as Figures 2 to 4As shown, the base 1 comprises a bottom plate 101, and a support column 102 pivotally connected to the bottom plate 101, the upper top plate 2, the lower top plate 3 and the locking plate 5 are all screwed on the support column 102. The support column 102 comprises a threaded segment 1021, a plug-in segment 1022 and an optical axis segment 1023. The threaded segment 1021 comprises an upwardly arranged positive rotation segment and a downwardly arranged reverse rotation segment. The driving member 401 is provided with a plug-in groove 4011 matched with the plug-in segment 1022. Driving the driving member 401 to rotate, the support column 102 rotates with the driving member 401, and the upper top plate 2 and the lower top plate 3 move in opposite directions along the axial direction of the support column 102.

[0059] In the embodiment, the bottom plate 101 and the support column 102 are arranged, and when the driving member 401 is plugged into the plug-in segment 1022, rotating the driving member 401 also drives the support column 102 to rotate, and the upper top plate 2 and the lower top plate 3 move in opposite directions due to the reason that they are inserted into the steel structure 7, so as to realize that the upper top plate 2 and the lower top plate 3 abut against the steel structure 7 at the same time, avoid the steel structure 7 from being extruded and deformed due to the external pressing plate exerting force on the steel structure 7 in the prior art, and ensure the structural integrity and rigidity requirement of the joint of the steel structure 7.

[0060] Further, as shown in Figure 1 and Figure 5 The plug-in groove 4011 is square, the plug-in segment 1022 is a rectangular protrusion arranged above the threaded segment 1021, and the plug-in segment 1022 is arranged outside the steel structure 7. By arranging the plug-in groove 4011 as a square, the processing is easy, and the stability of the connection between the plug-in segment 1022 and the plug-in groove 4011 can be improved, so that the rotating force for driving the support column 102 to rotate can be effectively guaranteed.

[0061] As shown in Figure 1 The driving member 401 of the embodiment is in a circular ring type, and a circular steel sheet can also be used. In actual application, the driving member 401 is detachably connected with the support column 102. Of course, more simply, the driving member 401 can also be a round bar, and a socket groove 6 is arranged on the round bar. After the two steel structures 7 are connected and fastened, the driving member 401 can be detached and used as a tool for splicing the next steel structure 7.

[0062] More specifically, the plug-in member 402 is in an "L" shape, and the plug-in member 402 comprises a support segment 4021 lapped on the driving member 401, and a vertical segment 4022 arranged perpendicularly to the support segment 4021. The socket 501 is shaped as a rectangular through groove, and the driving member 401 is further provided with a through groove accommodating the vertical segment 4022; the plug-in member 402 penetrates through the driving member 401 and is inserted into the rectangular through groove.

[0063] As mentioned above, the plug-in 402 is set in an "L" shape. When the plug-in 402 is inserted into the socket 501, the support section 4021 overlaps above the drive member 401 to prevent the plug-in 402 from detaching from the drive member 401. When the drive member 401 is engaged with the plug-in section 1022, the plug-in 402 can be inserted into the locking plate 5 at the same time, or it can be detached from the drive member 401. This allows the drive member 401 to first press the upper top plate 2 and the lower top plate 3 against the steel structure 7, and then insert the plug-in 402 into the locking plate 5 to drive the locking plate 5.

[0064] This design can accommodate steel structures 7 of different specifications. It is not only suitable for rectangular steel pipes, but also for I-shaped steel profiles. The width of the upper top plate 2 and the lower top plate 3 can be adjusted according to the width of different profiles. A pad can also be inserted between the inner cavity of the steel structure 7 and the upper top plate 2 or the lower top plate 3 to meet the positioning requirements of the steel structures 7 on both sides, ensure that the two steel structures 7 are connected in a corresponding manner, and improve the connection effect and connection strength.

[0065] As a preferred embodiment, the locking plate 5, as shown in the figure, includes a body 502 and a boss 503 provided on the body 502 and protruding upward, with a receiving portion 501 formed in the middle of the boss 503. By providing the boss 503, the height of the insert 402 inserted into the locking plate 5 is increased, ensuring the strength of the locking plate 5 when it rotates, and facilitating the stability of the insertion when the insert 402 passes through the steel structure 7 and the locking member.

[0066] Furthermore, preferably, such as Figures 2 to 4 As shown, both the upper top plate 2 and the lower top plate 3 are provided with sockets 6, and the steel structure 7 is provided with clearance grooves 701 corresponding to the sockets 6. The clearance grooves 701 are corresponding to the sockets 501, and the insert 402 is inserted through the steel structure 7 from top to bottom. After the upper top plate 2, the lower top plate 3, and the locking plate 5 lock the steel structure 7, the insert 402 is inserted into the steel structure 7 to prevent the connectors from separating from the steel structure 7 due to force. Furthermore, the upper top plate 2, the lower top plate 3, the bottom plate 101, and the locking plate 5 are pressed together as a whole. The insertion of the insert 402 in the longitudinal direction achieves a stable structure, thereby improving the integrity of the connection of the steel structure 7 and meeting the assembly requirements of the steel structure 7.

[0067] In this embodiment, the diameter of the optical axis segment 1023 is smaller than the side length of the insertion slot 4011. When the driving member 401 drives the locking plate 5 to rotate, the insertion slot 4011 is located on the optical axis segment 1023, and the driving member 401 rotates relative to the support column 102.

[0068] In addition, such as Figure 5As shown, the upper top plate 2 is provided with an upper groove 201 opening upward in the middle, and the lower top plate 3 is provided with a lower groove 301 opening downward in the middle. Two upper limit plates 8 are arranged in the upper groove 201 and abut against the groove wall respectively, and two lower limit plates 9 are arranged in the lower groove 301 and abut against the groove wall respectively. The steel structures 7 abut against the upper limit plates 8 and the lower limit plates 9. By arranging the upper limit plates 8 and the lower limit plates 9, the two steel structures 7 are positioned in the splicing direction, so that the accurate splicing of the plug-in part 402 is facilitated, and the splicing speed is improved.

[0069] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
