In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0041] When personnel need to connect the connection point of the beam column with the external steel beam, they need to use the external bolt structure to install it. At present, most of the steel structure beam column connection nodes are fixed together by welding, which is inconvenient to install and disassemble; and the beam column connection node has high requirements for the connection strength. The steel beam should not be easily pulled out after assembly. Therefore, a steel structure beam column fixing node is proposed to solve the above problems.

[0042] In this regard, the present application proposes a steel structure beam-column fixed node. After the steel beam 200 is inserted into the installation groove 310 of the mounting member 300, the fixing block 430 on the hinged plate 410 in the first fixing component 400 is inserted into the fixing hole 311 in the installation groove 310 to complete the primary locking. Then, the screw 510 in the second fixing component 500 can be screwed to allow the limit pin 521 to be inserted into the pin hole 210 of the steel beam 200 to complete the secondary locking. The disassembly and assembly are relatively convenient and the connection strength can meet the requirements.

[0043] In addition, the present application also proposes an assembly method for the above-mentioned steel structure beam-column fixed node, in which the steel beam 200 is quickly fixed by a first fixing component 400, and then the steel beam 200 is locked by a second fixing component 500. The assembly steps are simple and can effectively prevent the steel beam 200 from falling out of the installation groove 310.

[0044] The steel structure beam-column fixing node in the first embodiment of the present application includes a steel column 100, a steel beam 200, a mounting member 300, a first fixing assembly 400 and a second fixing assembly 500. Figure 1 , the steel column 100 is vertically arranged and the steel beam 200 is horizontally arranged, and the mounting member 300 is arranged between the steel column 100 and the steel beam 200 and connects the two together. Figure 2 and Figure 4 The first fixing assembly 400 and the second fixing assembly 500 are both arranged in the mounting member 300, and are used to fix the steel beam 200 in the mounting groove 310 of the mounting member 300, so as to prevent the steel beam 200 from loosening.

[0045] Specifically, refer to Figure 5 A pin hole 210 is provided on the side of the steel beam 200 for clamping and fixing with the second fixing assembly 500.

[0046] The mounting member 300 is mounted on the steel column 100 and is provided with a mounting groove 310 . The inner wall of the mounting groove 310 is provided with a fixing hole 311 and a cavity 312 .

[0047] Reference Figure 3The first fixing assembly 400 includes a hinge plate 410, a first elastic member 420 and a fixing block 430. One side of the hinge plate 410 is hinged to the end of the steel beam 200, and both ends of the first elastic member 420 are respectively connected to the hinge plate 410 and the steel beam 200 and drive the hinge plate 410 to flip outward. The fixing block 430 is installed on the hinge plate 410 and can slide into the fixing hole 311.

[0048] Reference Figure 5 The second fixing assembly 500 includes a screw rod 510 and a stopper 520. The stopper 520 is slidably disposed in the cavity 312. The screw rod 510 is threadedly connected to the stopper 520. Screwing the screw rod 510 can drive the stopper 520 to move. The stopper 520 is provided with a stopper pin 521 that can extend from the cavity 312 to the pin hole 210.

[0049] The working principle of the beam-column fixed node of the steel structure is as follows: after the end of the steel beam 200 is inserted into the installation groove 310, the hinge plate 410 located at the end of the steel beam 200 contacts the inner wall of the installation groove 310 and contracts under pressure, and at the same time, the first elastic member 420 is compressed to accumulate elastic potential energy. As the steel beam 200 is continuously inserted, when the fixing block 430 moves to the fixing hole 311, the first elastic member 420 releases the elastic potential energy and drives the fixing block 430 to slide into the fixing hole 311, completing the first-level locking. Subsequently, by screwing the screw 510, the limit pin 521 on the limit member 520 can be inserted into the pin hole 210 of the steel beam 200, completing the second-level locking. Through the double locking method, the steel beam 200 is stably fixed in the installation groove 310 and is not easy to loosen.

[0050] Furthermore, the number of the first fixing components 400 is an even number and they are symmetrically arranged in pairs. The steel beam 200 can be fixed in the center of the installation groove 310 through the symmetrically arranged first fixing components 400, thereby achieving a center-clamping and fixing effect.

[0051] Furthermore, the hinge plate 410 extends out from the mounting slot 310 , and the end of the hinge plate 410 extending out from the mounting slot 310 is pressed to compress the first elastic member 420 , and the fixing block 430 is disengaged from the fixing hole 311 , so that the steel beam 200 can be removed from the mounting slot 310 .

[0052] Furthermore, a slide groove 313 is provided in the cavity 312 , and the limiting member 520 slides along the slide groove 313 , so as to limit the moving direction of the limiting member 520 and prevent the limiting member 520 from being offset when sliding.

[0053] Furthermore, the second fixing assembly 500 further includes a transmission rod 530 and a transmission mechanism. The screw rod 510 is arranged along the radial direction of the steel beam 200, and the transmission rod 530 is arranged along the axial direction of the steel beam 200. Both the screw rod 510 and the transmission rod 530 are meshed with the transmission mechanism and are transmitted through the transmission mechanism, so that the screw rod 510 can be driven to rotate by screwing the axially arranged transmission rod 530.

[0054] Specifically, in some embodiments, the transmission mechanism is a bevel gear mechanism, and both the screw 510 and the transmission rod 530 are equipped with bevel gears. The bevel gear on the screw 510 meshes with the bevel gear on the transmission rod 530, thereby realizing the linkage between the screw 510 and the transmission rod 530 through the bevel gear mechanism.

[0055] In this embodiment, the transmission mechanism is specifically a worm gear mechanism, the transmission rod 530 is specifically a worm, the screw rod 510 is equipped with a worm wheel 540, and the worm wheel 540 is meshed with the worm.

[0056] Optionally, the second fixing assembly 500 further includes a telescopic rod 550 and a pull plate 560. The mounting member 300 is provided with a through hole. The telescopic rod 550 is connected to the transmission rod 530. The end of the telescopic rod 550 passes through the through hole and is provided with the pull plate 560. When the transmission rod 530 needs to be screwed, the user can hold the pull plate 560 and pull it outward, and then screw the telescopic rod 550 to drive the transmission rod 530 to rotate, thereby driving the screw 510 to rotate; when the transmission rod 530 does not need to be screwed, the user can drive the pull plate 560 to retract to prevent it from being exposed and interfering with other external components.

[0057] Furthermore, the second fixing assembly 500 further includes a second elastic member 570 , which is connected to the telescopic rod 550 and drives the telescopic rod 550 to contract, so that when there is no need to screw the transmission rod 530 , the second elastic member 570 can automatically drive the pull plate 560 to retract.

[0058] Specifically, in the present application, the first elastic member 420 and the second elastic member 570 are both springs.

[0059] An assembly method for the above-mentioned steel structure beam-column fixed node in the second embodiment of the present application includes the following steps:

[0060] S100. Insert the steel beam 200 into the mounting groove 310 of the mounting member 300;

[0061] S200. The hinge plate 410 contacts the inner wall of the mounting groove 310, and as the steel beam 200 is continuously inserted, the first elastic member 420 is compressed;

[0062] S300. The fixing block 430 on the hinged plate 410 reaches the fixing hole 311, and the first elastic member 420 is released and drives the fixing block 430 to slide into the fixing hole 311;

[0063] S400. Screw the screw 510 to move the stopper 520 toward the direction of the steel beam 200;

[0064] S500. The limiting pin 521 on the limiting member 520 is inserted into the pin hole 210 of the steel beam 200 to complete the locking.

[0065] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
