[0037] In one embodiment, the first fastener and the second fastener include bolts or nuts, which are easy to use, firmly connected and highly interchangeable.

[0038] In one embodiment, the shock absorbing device includes a horizontally arranged bottom plate 10, a vertically arranged side plate 12 and a plurality of shock absorbing components; the side plate 12 is connected to the bottom plate 10; the two ends of the side plate 12 are respectively connected to the two groups of the first connecting plates 3; the two ends of the bottom plate 10 are respectively connected to the two groups of the second connecting plates 4; the side plate 12, the bottom plate 10 and the two groups of the second connecting plates 4 enclose a receiving cavity with an L-shaped opening; each of the shock absorbing components is vertically arranged in the receiving cavity.

[0039] In one of the embodiments, the base plate 10 is integrally formed with the upper surface of the prefabricated column 1; the shock absorbing assembly, the first connecting member and the second connecting member are separately arranged in partitions, which not only facilitates installation but also prevents mutual influence between the connecting members and the shock absorbing assemblies and interference.

[0040] In one embodiment, several groups of the shock absorbing assemblies near the side panel 12 are connected to the side panel 12 via a third fastener; several groups of the shock absorbing assemblies near the second connecting plate 4 are connected to the second connecting plate 4 via a fourth fastener; and several groups of the shock absorbing assemblies near the prefabricated beam 2 are connected to the connecting rod via a fifth fastener.

[0042] In one embodiment, the third fastener, the fourth fastener, the fifth fastener, the sixth fastener and the seventh fastener are bolts or nuts, which are easy to use, firmly connected and highly interchangeable.

[0043] In one embodiment, the shock absorbing assembly includes a plurality of buffer members 13 and a plurality of first elastic members 14; the buffer members 13 of the same group of the shock absorbing assemblies are connected by the first elastic members 14; the buffer members 13 of two adjacent shock absorbing assemblies on the same horizontal plane are connected by the second elastic member 17.

[0044] Specifically, through the above arrangement, each of the shock absorbing components forms an effectively connected force transmission mechanism with the prefabricated column 1 and the prefabricated beam 2; at the same time, each of the buffer members 13 is arranged in an array to form a multi-dimensional shock absorbing system, and no matter which angle the impact force is received, it can be effectively converted into impact force in the horizontal and vertical directions, and the shock absorbing components and each of the second elastic members 17 can effectively mitigate and consume the vibration energy, thereby improving the overall seismic performance of the connection structure; at the same time, even if a certain shock absorbing component is damaged, the transmission of the vibration energy will not be affected by the multi-dimensional connection relationship, and the overall stability of the structure is high;

[0045] When an earthquake occurs, the prefabricated column 1 and the prefabricated beam 2 will convert the vibrations they receive into impact forces in the horizontal direction and the vertical direction; each of the buffers 13 and each of the first elastic members 14 will deform after receiving the impact forces in the vertical direction; each of the second elastic members 17 will also deform after receiving the impact forces in the horizontal direction; each of the buffers 13 and each of the elastic members will convert the deformation into elastic potential energy, thereby mitigating and consuming the vibration energy, and avoiding the displacement of the prefabricated beam 2 or the prefabricated column 1; at the same time, when the earthquake intensity is large and relative displacement occurs between the prefabricated beam 2 and the prefabricated column 1, the shock absorbing assembly, the second elastic member 17 and the beam-column composition Energy dissipation system, through the consumption of earthquake energy by the shock absorbing assembly and the second elastic member 17, the seismic resistance of the prefabricated column 1 and the prefabricated beam 2 can be effectively improved; when the impact force disappears, due to the strong restoring force of each of the buffer members 13, each of the first elastic members 14 and each of the second elastic members 17, the relative position between the beam and the column after the earthquake can basically be restored to the pre-earthquake state, thereby improving the self-resetting ability of the beam and the column, thereby improving the seismic resistance of the frame structure; the number and specifications of each of the buffer members 13, each of the first elastic members 14 and the second elastic member 17 can be reasonably selected or added as needed to further improve the seismic resistance of the beam-column connection structure.

[0046] In one embodiment, the buffer 13 is made of shock-absorbing material; the shock-absorbing material includes sponge, rubber, pearl cotton or PU foam, which can absorb and consume vibration energy; the outer periphery of the buffer 13 is provided with a plurality of corrugated protrusions and a plurality of corrugated grooves distributed at equal intervals, and the adjacent protrusions and grooves form a curved portion; when the buffer 13 is impacted and shrinks, the impact can be effectively buffered and vibration energy can be consumed through the curved portion.

[0047] In one embodiment, the first elastic member 14 and the second elastic member 17 can both be shock-absorbing springs. When impacted, the shock-absorbing springs can use their own deformation to absorb the impact and thus reduce shock. At the same time, the first elastic member 14 and the second elastic member 17 can also be reasonably selected or replaced with common means of the prior art as needed.

[0048] In one embodiment, the first elastic member 14 includes a sleeve and a shock-absorbing rod; the shock-absorbing rod is arranged in the sleeve; an elastic material layer is provided between the shock-absorbing rod and the sleeve; the elastic material layer includes rubber, silicone or sponge; the inner diameter of the sleeve is larger than the outer diameter of the elastic material layer, so that a certain space is reserved between the elastic material layer and the inner wall of the sleeve to accommodate the deformation of the elastic material layer during the extrusion process; when an earthquake occurs, the first elastic member 14 is extruded and deformed by the elastic material layer to consume the earthquake energy.

[0049] In one embodiment, the second elastic member 17 includes a buffer spring, a pull rod, a first offset plate and a second offset plate; the buffer spring is sleeved on the pull rod, one end of the pull rod is connected to the first offset plate, and the other end of the pull rod is connected to the second offset plate; the surfaces of the first offset plate and the second offset plate are covered with uneven rolling patterns; when an earthquake occurs, the buffer spring converts the energy received into elastic potential energy to buffer the vibration, and the uneven rolling patterns on each of the offset plates increase the friction between the second elastic member 17 and each of the buffer members 13, converting the received energy into heat to further consume the earthquake energy, so that the impact energy generated by the earthquake is offset to the maximum extent.

[0050] In one embodiment, the stopper 15 includes a stopper cylinder 16, a buffer rod 18, a sealing ring 19 and a stopper spring 9; the stopper cylinder 16 is provided with a stroke chamber 20 with one end open and the other end closed, and a buffer chamber 21 located outside the stroke chamber 20 and in a circular ring shape with both ends closed; a plurality of connecting holes 23 connecting the stroke chamber 20 and the buffer chamber 21 are provided on the side wall of the stroke chamber 20; the apertures of the plurality of connecting holes 23 increase in sequence along the bottom of the stroke chamber 20 toward the direction of the shock absorbing assembly; one end of the buffer rod 18 is provided in the stroke chamber 20 The buffer rod 18 is provided outside the stroke chamber 20 and is connected to the bottom end of the shock absorbing assembly; the stop spring 9 is provided in the buffer chamber 21 and one end of the stop spring 9 is fixedly connected to one end of the buffer chamber 21 close to the shock absorbing assembly; the other end of the stop spring 9 is fixedly connected to the sealing ring 19; the sealing ring 19 is connected to the inner wall of the buffer chamber 21 in a sliding and sealing manner; an air vent 22 is provided on the outer wall of the buffer chamber 21 on the side in contact with the stop spring 9.

[0051] The diameter of the buffer rod 18 is equal to the inner diameter of the stroke chamber 20; when an earthquake occurs, the impact force is transmitted to the buffer rod 18, and the impact force reciprocates to vibrate, thereby causing the buffer rod 18 to reciprocate, and during its movement, part of the connecting hole 23 will be blocked or exposed, thereby forming flow channels of different calibers; when the buffer rod 18 is pressed down, the caliber of the flow channel gradually decreases, resulting in the medium in the stroke chamber 20 failing to flow into the buffer chamber 21 through the flow channel in time and being compressed, thereby generating a large supporting force to alleviate the downward pressure trend of the buffer rod 18; the sealing ring 19 and the stop spring 9 can further buffer the impact force, and the sealing ring 19 rubs against the walls of the stroke chamber 20 and the buffer chamber 21 to generate heat to achieve energy dissipation; the stop spring 9 achieves energy dissipation by deformation, thereby further improving the overall buffering effect;

[0052] At the same time, when the buffer rod 18 rises, the diameter of the flow channel becomes larger, causing a large amount of medium in the stroke chamber 20 to flow into the buffer chamber 21, resulting in the formation of a relative negative pressure in the stroke chamber 20, thereby generating suction on the buffer rod 18, thereby buffering the upward trend of the buffer rod 18; the above design is used to generate an elastic-hysteresis phenomenon with significant energy dissipation characteristics, thereby improving the shock absorption effect and the stability of the connecting structure; the medium includes gas or liquid and has certain flow properties.

[0053] In one embodiment, the connecting rod includes a plurality of U-shaped rods 11 adapted to the shock absorbing assembly; the plurality of U-shaped rods 11 are arranged in parallel inside the prefabricated beam 2 and the ends of the U-shaped rods 11 are arranged outside the beam body of the prefabricated beam 2; and each of the ends is respectively connected to each of the shock absorbing assemblies close to the prefabricated beam 2.

[0054] Specifically, the connecting rod includes a plurality of U-shaped rods 11 with openings facing the top end of the precast beam 2; each buffer member 13 of each shock-absorbing assembly is connected to the U-shaped rod 11 through the fifth fastener, thereby making the connection structure firm and stable; in the case of convenient operation, the U-shaped rod 11 is connected to the beam stirrup 8 through reinforcing ribs to improve the positioning stability of the U-shaped rod 11.

[0055] In one embodiment, the prefabricated column 1 is provided with a plurality of column stirrups 5; the plurality of column stirrups 5 are arranged at equal intervals along the length direction of the first connecting member and are sleeved on the outer periphery of the two groups of the first connecting members; the prefabricated beam 2 is provided with a plurality of beam stirrups 8; the plurality of beam stirrups 8 are arranged at equal intervals along the length direction of the second connecting member and are sleeved on the outer periphery of the connecting rod and the two groups of the second connecting members.

[0056] In one embodiment, the prefabricated column 1 also includes column longitudinal reinforcement; the column stirrups 5 bundle the first connecting piece and the column longitudinal reinforcement into shape and pour concrete to form the column body of the prefabricated column 1; the prefabricated beam 2 also includes beam longitudinal reinforcement; the beam stirrups 8 bundle the second connecting piece, the beam longitudinal reinforcement and the connecting rod into shape and pour concrete to form the beam body of the prefabricated beam 2; by adding the column stirrups 5 and the beam stirrups 8, the structures of the prefabricated column 1 and the prefabricated beam 2 are more stable, the force transmission mechanism is clear and reasonable, and the force effect is improved.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
