[0024] The technical solutions in the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] As Figures 1 to 3 shown, an embodiment of the present utility model provides a connection node for a steel structure frame, which is used to connect a beam-column 1 and a cross beam 2, and includes:

[0026] Two mounting plates 3, the two mounting plates 3 are arranged in a mirror image and form a mounting position for mounting the beam-column 1;

[0027] Two connecting seats 4, the two connecting seats 4 are respectively fixed on the two mounting plates 3, and the cross beam 2 is clamped on the connecting seats 4;

[0028] A fastening assembly, including two fixing blocks 5 slidably arranged on the connecting seats 4 and an adjusting member rotatably arranged on the connecting seats 4, the adjusting member is in transmission connection with the two fixing blocks 5, and is used to drive the fixing blocks 5 to protrude from the connecting seats 4 and clamp on the cross beam 2, or be received in the connecting seats 4 and separated from the cross beam 2; and

[0029] Fasteners, connected between the two mounting plates 3 and passing through the beam-column 1.

[0030] In the embodiment of the present utility model, the shape of the mounting plate 3 is U-shaped. When the two mounting plates 3 are buckled with each other, a certain space, that is, a mounting position, can be formed between the two mounting plates 3. When splicing the beam-column 1 and the cross beam 2, first buckle the two mounting plates 3 on both sides of the beam-column 1, and tighten the two mounting plates 3 with the cooperation of the fasteners, quickly fix the two mounting plates 3 at a certain point on the beam-column 1, and provide a mounting position for the subsequent installation of the cross beam 2. After the installation is completed, directly clamp the end of the cross beam 2 onto the connecting seat 4 of the corresponding mounting plate 3, so that the connecting seat 4 penetrates into the inside of the cross beam 2 to complete the preliminary installation of the cross beam 2. At the same time, with the cooperation of the fastening assembly, by rotating the adjusting member, the two fixing blocks 5 can synchronously protrude from the connecting seats 4 and be clamped onto the through holes of the cross beam 2, so as to limit the position of the cross beam 2 and prevent it from moving. Then, the cross beam 2 can be quickly fixed onto the connecting seat 4, realizing rapid assembly, saving time and manpower. And later, when disassembling the cross beam 2, only need to rotate the adjusting member again, so that the two fixing blocks 5 are synchronously received into the connecting seats 4 to release the limit on the cross beam 2, which is convenient for disassembling for transportation and ensures the original structure, facilitating subsequent reuse.

[0031] Based on the above solution, as Figure 4As shown in the figure, the adjusting member includes a bidirectional screw 6. The bidirectional screw 6 is rotatably arranged on the connecting seat 4. Both fixing blocks 5 are threadedly connected to the bidirectional screw 6. One end of the bidirectional screw 6 is provided with a limiting block 7, and the other end is provided with an adjusting nut 8. Specifically, when fixing the cross beam 2 through the cooperation of the adjusting member, the adjusting nut 8 of the bidirectional screw 6 can be directly rotated. Under the action of the limiting block 7 and the adjusting nut 8, the bidirectional screw 6 can only rotate on the connecting seat 4. Therefore, the fixing blocks 5 at both ends can be directly driven to move away from each other, so that the ends of the fixing blocks 5 synchronously extend out of one side of the connecting seat 4 and gradually snap into the through holes of the cross beam 2, realizing the axial limiting of the cross beam 2 and ensuring stability.

[0032] Specifically, as Figure 4 shown in the figure, a guiding inclined surface 11 is provided at the end of the fixing block 5. When the through hole of the cross beam 2 and the end of the fixing block 5 are not aligned, while the fixing block 5 is moving, the guiding inclined surface 11 can be used to squeeze the mouth of the through hole, so that the mouth of the through hole is stressed and squeezes the cross beam 2, so that the end of the fixing block 5 is finally completely snapped into the mouth of the cross beam 2, which is convenient for positioning and installation.

[0033] Specifically, as Figure 1 and Figure 3 shown in the figure, the width of the fixing block 5 is the same as the inner diameter of the connecting seat 4. The fixing block 5 can be limited through the inner side of the connecting seat 4 to prevent the fixing block 5 from rotating with the bidirectional screw 6.

[0034] Based on the above scheme, as Figure 3 shown in the figure, the fastener includes a connecting screw 13 and a fastening nut 14 adapted thereto. The connecting screw 13 is arranged between the two mounting plates 3 and penetrates through the inside of the beam column 1. First, determine the position of the mounting plate 3 installed on the beam column 1, and then open a hole for installing the connecting screw 13. When the two mounting plates 3 are placed below the hole, the connecting screw 13 is sequentially passed through one of the mounting plates 3, the hole and the other mounting plate 3. Finally, under the action of the fastening nut 14, the two mounting plates 3 are installed on the beam column 1. At the same time, as Figure 2 shown in the figure, multiple holes can be selected on the beam column 1. When the cross beam 2 is vertically installed or installed in a "cross" shape, different groups of mounting plates 3 can be installed at different hole positions to realize the multi-directional splicing of the cross beam 2.

[0035] Specifically, as Figure 3 shown in the figure, a limiting ring 10 is provided on the connecting seat 4. The end of the cross beam 2 abuts against the side surface of the limiting ring 10. Under the action of the limiting ring 10, the installation of the cross beam 2 can be positioned. When the cross beam 2 abuts against the limiting ring 10, the through hole of the cross beam 2 corresponds to the position of the fixing block 5.

[0036] Specifically, as Figure 3As shown, a number of reinforcing ribs 12 are provided on the side surface of the connecting seat 4. The number of reinforcing ribs 12 are connected between the mounting plate 3 and the limiting ring 10, which can increase the connection area between the connecting seat 4 and the mounting plate 3 and enhance the connection strength between the two.

[0037] Specifically, as Figure 3 shown, a limiting rod 9 is provided on one of the mounting plates 3, and the limiting rod 9 passes through the other mounting plate 3. The two mounting plates 3 can be limited under the action of the limiting rod 9. When not in use, the two mounting plates 3 can be ensured not to separate, which is convenient for carrying.

[0038] In summary, under the action of the two mounting plates 3, it can not only be fixed at different positions on the beam-column 1, but also the formed mounting position can be adjusted to be mounted on different beam-columns 1. By changing the position of the mounting plate 3 on the beam-column 1, the cross beam 2 can be vertically mounted or mounted in a "cross" shape, providing a variety of assembly methods. And under the action of the fastening component, the cross beam 2 clamped on the connecting seat 4 can be limited and fixed or the limit can be released by adjusting the two fixing blocks 5 through the bidirectional screw rod 6, which not only realizes rapid installation but also facilitates subsequent disassembly for recycling.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
