The outer side of side plate 7 is provided with reinforcing rib 17, reinforcing rib 17 is arranged along the length direction of side plate 7, for enhancing the structural strength of connecting frame 1, prevent deformation in the process of frequent disassembly and assembly.

[0029] The locking assembly 2 is arranged inside the connecting frame 1 and used to fix the steel member body to the connecting frame 1. The locking assembly 2 comprises a plurality of clamping pieces 4 and a driving rod 5. The number of the clamping pieces 4 is four, which are evenly distributed on both sides of the connecting frame 1. One end of each clamping piece 4 is hinged to the inner wall of the connecting frame 1, and the other end is provided with an embedded block 6. The end of the embedded block 6 is provided with a tapered surface 16, which is used to automatically correct the position when the embedded block 6 is inserted into the positioning hole, reducing the need for manual adjustment. The hinged end of the clamping piece 4 is connected with the side plate 7 through a sliding groove 9. The arc design of the sliding groove 9 ensures the stability and accuracy of the clamping piece 4 during rotation. The driving rod 5 is threadedly connected to the connecting frame 1 and hinged to the middle part of the clamping piece 4. The axial movement of the driving rod 5 drives the clamping piece 4 to rotate around the hinge point, thereby achieving the insertion or withdrawal of the embedded block 6. The outer side of the driving rod 5 is provided with a guide groove 13 extending along the axial direction of the driving rod 5, which is used to limit the movement direction of the connecting rod 11 and ensure the stable axial movement of the driving rod 5.

[0030] The unlocking mechanism 3 is mounted on the side of the connecting frame 1 and is in transmission connection with the locking assembly 2.

[0034] In order to better enable relevant persons in the art to fully understand and implement the present application, the specific implementation principle of the present application is further supplemented in the following in combination with a specific application scenario.

[0035] In the construction process of the assembled steel structure building, the steel member needs to be frequently installed and disassembled to adapt to different construction requirements. For example, when connecting the beam and the column, first, the beam end is butted with the pre-set connecting frame 1 on the side of the column. The connecting frame 1 is composed of two oppositely arranged side plates 7 and a bottom plate 8, and the through holes 15 on the bottom plate 8 correspond one-to-one with the positioning holes of the beam end, so that the embedding blocks 6 can be accurately inserted into the positioning holes. The inner wall of the side plate 7 is provided with an arc-shaped sliding groove 9 for guiding the rotating track of the clamping piece 4, so as to ensure the stability of the clamping piece 4 during movement.

[0036] When the beam end is placed inside the connecting frame 1, the operator manually rotates the unlocking handle 10. The unlocking handle 10 is hinged to the driving rod 5 through the connecting rod 11, and the rotation drives the driving rod 5 to move along the axial direction. The outer side of the driving rod 5 is provided with a guide groove 13, and the guide block 14 at the end of the connecting rod 11 is embedded in the guide groove 13, which limits the movement direction of the driving rod 5, so as to ensure the stable axial movement of the driving rod 5. The movement of the driving rod 5 further drives the clamping piece 4 to rotate around the hinge point, and the embedding block 6 at the other end of the clamping piece 4 is inserted into the positioning hole of the beam end. The tapered surface 16 at the end of the embedding block 6 automatically corrects the position during insertion, reducing the workload of manual adjustment and realizing the quick fixing function.

[0037] When the beam component needs to be disassembled after the construction is completed, the unlocking handle 10 is operated reversely. The rotation of the unlocking handle 10 is transmitted to the driving rod 5 through the connecting rod 11, the driving rod 5 is retracted, the clamping piece 4 is rotated to the initial position, and the embedded block 6 is withdrawn from the positioning hole. At this time, the buckle 18 at the end of the unlocking handle 10 locks the position of the unlocking handle 10, avoiding the misoperation to cause the locking assembly 2 to be clamped again. The reset spring 12 is sleeved outside the driving rod 5, and the two ends thereof are fixedly connected with the connecting frame 1 and the driving rod 5, respectively. When the unlocking handle 10 is reset, the driving rod 5 is pushed to return to the initial position, so that the next installation is prepared.

[0038] In addition, the side plate 7 of the connecting frame 1 is provided with a reinforcing rib 17 outside. The reinforcing rib 17 is arranged along the length direction of the side plate 7, so that the overall structural strength of the connecting frame 1 is enhanced, and deformation in the frequent disassembly process is prevented. The number of the clamping pieces 4 is four and is uniformly distributed. The embedded block 6 of each clamping piece 4 is independently controlled, so that the beam component body of different sizes can be adapted, and the applicability of the device is improved.

[0039] Through the above steps and structure design, the utility model realizes the quick fixing and releasing function of the steel component body. The taper surface 16 of the embedded block 6 is designed in combination with the guiding action of the arc-shaped sliding groove 9, so that the convenience of installation and disassembly is optimized. The overall structure design is reasonable, the matching relationship between the parts is clear, the disassembly steps and time cost are significantly reduced, and the demand of the high-frequency disassembly scene is met.

[0040] The above only describes the preferred embodiment of the utility model, and does not limit the utility model. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
