Description

[0002] The RCS composite joint structure, or reinforced concrete column-steel beam composite frame structure, is a novel structural system that combines the advantages of reinforced concrete columns and steel beams. In practical applications, RCS composite joints often withstand complex loads from various directions, including static and dynamic loads. Especially during natural disasters such as earthquakes, the structure is subject to intense dynamic impacts, placing extremely high demands on the joint's seismic resistance. Therefore, the seismic load-bearing capacity of RCS composite joints not only affects the stability of the overall structure but also directly impacts the safety and service life of the building.

[0003] To ensure the reliability and safety of the newly designed RCS composite node structure under extreme conditions such as earthquakes, its seismic performance must be comprehensively tested and evaluated multiple times using testing equipment.

The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control.

[0022] See also Figure 1-4 , an RCS composite node seismic performance testing device, comprising a base 1 and two node test pieces 2, wherein a longitudinal vibration structure is installed on the base 1, and a lateral movement structure is installed on the longitudinal vibration structure;

[0023] It should be noted that the node test piece 2 was manufactured according to the standard, and the node test piece 2 was installed on the transverse moving structure, and the vibration test was carried out by cooperating the longitudinal vibration structure with the transverse moving structure;

[0024] Specifically, the transverse movement structure includes a mounting base 3, a slide groove 4 is provided on the mounting base 3, a slider 5 is movably installed on the slide groove 4, a fixed base 6 is installed on the slider 5, a clamping assembly is provided on the fixed base 6, two node test pieces 2 are mounted on the fixed base 6 through the clamping assembly, ropes 7 are installed on both side walls of the fixed base 6, a winch 8 is installed at one end of the rope 7, a support plate 9 is installed on the winch 8, and the support plate 9 is installed on the outer wall of the base 1;

The two mounting grooves 10 are provided on the upper wall of the fixing seat 6, and an operating groove 11 is provided on the upper wall of the fixing seat 6 and located in the center of the two mounting grooves 10. A connecting hole is provided between the two mounting grooves 10 and the operating groove 11, and a clamping block 12 is movably inserted into the connecting hole. A mounting frame 13 is installed on the inner bottom surface of the operating groove 11, and a rotating rod 14 is movably inserted into the mounting frame 13. Two threads are provided at both ends of the rotating rod 14, and the rotation directions of the two threads are set in opposite directions. The clamping block 12 is movably sleeved on the rotating rod 14 through the thread.

[0027] It should be noted that the two node test pieces 2 are respectively inserted into the two mounting grooves 10. The rotation of the rotating rod 14 can make the clamping blocks 12 on both sides move in the communicating holes under the connection of the two threads until they are clamped on the node test piece 2, thereby fixing the node test piece 2. Subsequently, the vibrator 16 works to make the transverse moving structure vibrate up and down through multiple spring columns 15 to simulate longitudinal waves in earthquake waves. The winches 8 on both sides of the base 1 work in opposite directions, that is, one winds up the rope 7 and the other lets out the rope 7. The winches 8 on both sides exchange working states back and forth, and the fixed seat 6 is pulled to move back and forth laterally by the rope 7. The fixed seat 6 moves in the slide groove 4 through the slider 5, which plays a guiding role and simulates transverse waves in earthquake waves. Two test pieces can be tested simultaneously in one operation, thereby improving experimental efficiency.

When the rotating rod 14 is rotated until the clamping block 12 is clamped on the node test piece 2, the bolt 17 is rotated so that one end of the bolt 17 presses the rotating rod 14 to fix the rotating rod 14.

[0030] As a preference, further, the shape of the communicating hole is a polygonal structure, and the clamping block 12 matches the communicating hole to prevent the clamping block 12 from rotating in the communicating hole;

[0031] As a preference, further, a polygonal protrusion 18 is fixedly mounted on the rotating rod 14 to facilitate the user to rotate the rotating rod 14 using a wrench.
