Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Embodiment 1: This embodiment provides a stirrup assembled shear wall structure. Refer to Figure 1-8 , specifically, it includes a fixing plate 1. The four diagonal corners of the fixing plate 1 are all chamfered. Shear walls 3 are provided in the four diagonal directions of the fixing plate 1. The four shear walls 3 are distributed in a "field" shape. A cross beam 2 is provided between each pair of adjacent shear walls 3. The fixing plate 1 and the four cross beams 2 are distributed in a "cross" shape. The fixing plate 1 serves as the basic fixing component of the entire structure. By connecting and fixing with the cross beam 2, it provides support and positioning reference for the entire device; The cross beam 2 is one of the main load-bearing components of the structure, bearing a certain weight and external force. It is assembled with the shear wall 3. Its gravity and the mutual extrusion with the shear wall 3 trigger the movement of a series of components, such as driving the concentric rod 24 to slide along the hollow sleeve 41, etc. It realizes the assembly and clamping fixation with the shear wall 3 and jointly constitutes a stable structural framework; The shear wall 3 cooperates with the cross beam 2 to jointly build a stable structural system, enhancing the shear resistance and stability of the entire structure. During the assembly process, its circular grooves 31, circular stoppers 33, arc-shaped clamping grooves 32 and other structures interact with components such as the concentric rod 24, load-bearing plate 4, arc-shaped clamping plate 47, etc. to realize the assembly and clamping fixation with the cross beam 2 and ensure the integrity of the structure; A number of equally spaced circular grooves 31 are provided on each of the four side surfaces of the shear wall 3. A number of equally spaced concentric discs 21 are fixedly provided on each of the two side surfaces of the cross beam 2. A concentrically distributed concentric rod 24 is fixedly provided in the middle of each concentric disc 21. A hollow sleeve 41 is slidably sleeved on the outer end of each concentric rod 24. The concentric rod 24 and the hollow sleeve 41 at the same position are inserted into the corresponding circular groove 31; With the gravity and mutual extrusion of the cross beam 2 and the shear wall 3, the concentric rod 24 slides along the hollow sleeve 41, thereby driving the movement of other components, driving the positioning pin 26 to slide along the U-shaped opening 43. It is a key component for transmitting motion and force, providing support and guidance for the expansion of the arc-shaped outer expansion plate 44, enabling it to expand outward along itself and the hollow sleeve 41 and abut against the inner wall of the circular groove 31 to realize the further fixation of the cross beam 2 and the shear wall 3; The hollow sleeve 41 provides a sliding track for the concentric rod 24, enabling the concentric rod 24 to slide smoothly inside it and ensuring the relative movement between components; at the same time, during the expansion process of the arc-shaped outer expansion plate 44, it jointly provides support and guidance for the arc-shaped outer expansion plate 44 with the concentric rod 24 to ensure that it can accurately abut against the inner wall of the circular groove 31 to realize the assembly and fixation of the structure; Two pairs of fixedly distributed fixed anchor bolts 22 are fixedly provided at both ends of the cross beam 2. The fixed anchor bolts 22 are used to fix the outer ends of the fixed steel wires 110, providing an anchoring point for the fixed steel wires 110 to ensure that the fixed steel wires 110 can effectively connect the fixed plate 1 and the cross beam 2 together during the tightening process and ensure the stability of the structure. Driven shafts 17 are rotatably inserted in the middle of the side edges of the front and rear sides of the fixed plate 1. Concentrically fixed wire wheels 19 are sleeved on the outer ends of each driven shaft 17. Fixed steel wires 110 are fixedly wound on each wire wheel 19; The outer end of each fixing wire 110 is wound into a triangular shape, and the outer end of each fixing wire 110 is sleeved on the outer ends of a pair of fixing anchor rods 22 on the same side. The outer end of the fixing wire 110 is wound around the corresponding pair of fixing anchor rods 22 in a triangular shape, and is tightened by the rotation of the wire wheel 19, so as to fix and lock the fixing plate 1 and the four cross beams 2 to each other. It is an important component for realizing the connection and fixation of the fixing plate 1 and the cross beam 2. Through the synergistic action of components such as the fixing wire 110 and the gear disc 12, it is fixed and locked with the four cross beams 2 to ensure the stability of the entire structure. Embodiment 2: On the basis of Embodiment 1, this embodiment further includes: In the specific implementation process, as Figure 2 、 Figure 6 and Figure 8 shown, a tension spring 27 is fixedly arranged at the outer end of the concentric rod 24. The outer end of the tension spring 27 is fixedly inserted into the hollow sleeve 41. The tension spring 27 is compressed and deformed under the drive of the positioning pin 26, storing elastic potential energy. Its elastic force provides a certain buffer and restoring force for the entire assembly process, ensuring the stability and reliability of the components during the movement process, and at the same time maintaining the connection and interaction between the components to a certain extent; Four U-shaped openings 43 distributed in a circular shape are formed on the outer ring surface of the hollow sleeve 41. Four positioning pins 26 distributed in a circular shape are fixedly arranged on the outer ring surface of the concentric rod 24. The outer end of each positioning pin 26 is slidably engaged in the U-shaped opening 43 on the same side. The positioning pin 26 slides along the U-shaped opening 43 as the concentric rod 24 slides, playing a role of positioning and guiding, ensuring the accurate movement direction and position of the concentric rod 24, and at the same time driving corresponding actions with the tension spring 27; A first rectangular collar 25 is concentrically sleeved on the middle part of the concentric rod 24. First ear seats are fixedly arranged in the middle of the four side surfaces of the first rectangular collar 25. A pair of movably hinged first connecting rods 28 are arranged at the outer end of each first ear seat. As the cross beam 2 and the shear wall 3 are assembled, the distance between the first rectangular collar 25 and the second rectangular collar 42 decreases. Through the cross-hinged action of the first connecting rods 28 and the second connecting rods 210, the limit pin 29 is driven to slide along the elliptical pin hole, thereby triggering a series of subsequent component movements and realizing the assembly and clamping fixation of the structure. It is an important connecting component for transmitting motion and force; A second rectangular collar 42 is concentrically and fixedly sleeved on the outer end of the hollow sleeve 41. Second lugs are fixedly arranged in the middle of the four side faces of the second rectangular collar 42. A pair of movably hinged second connecting rods 210 are arranged at the outer ends of each second lug. A pair of first connecting rods 28 and second connecting rods 210 on the same side are distributed in an "X" shape and are movably hinged coaxially in the middle. The first connecting rods 28 and the second connecting rods 210 convert the change in the distance between the first rectangular collar 25 and the second rectangular collar 42 into the sliding movement of the limit pin shaft 29 through the cross-hinged method, thereby driving the arc-shaped outer expansion plate 44 and the arc-shaped clamping plate 47 to act, realizing the assembly clamping and fixing of the cross beam 2 and the shear wall 3, and it is a key component for realizing the movement transmission and conversion between components; Four arc-shaped outer expansion plates 44 distributed in a circular shape are arranged on the outer side faces of the concentric rod 24 and the hollow sleeve 41. Single lugs 46 and limit plates 45 are fixedly arranged at both ends of the inner side face of the arc-shaped outer expansion plate 44, and oval pin holes are formed in the limit plates 45. The arc-shaped outer expansion plates 44 expand outward along the concentric rod 24 and the hollow sleeve 41 and abut against the inner wall of the circular groove 31, increasing the contact area and friction of the structure, further improving the stability and reliability of the assembly of the cross beam 2 and the shear wall 3, and playing a role in strengthening the fixation; The outer ends of each pair of second connecting rods 210 are movably hinged to the outer ends of the single lugs 46 on the same side. The outer ends of each pair of first connecting rods 28 are hinged with limit pin shafts 29 arranged in a penetrating manner, and the middle of each limit pin shaft 29 is slidably inserted into the oval pin hole on the same side. Driven by the first connecting rods 28 and the second connecting rods 210, the limit pin shafts 29 slide along the oval pin holes, providing a limiting and guiding function for the entire movement process, ensuring that each component moves along a predetermined trajectory and manner, so as to realize accurate assembly clamping and fixing; A circular stopper 33 is fixedly arranged in the circular groove 31. A load-bearing disc 4 is fixedly arranged at the outer end of the hollow sleeve 41. The load-bearing disc 4 abuts against the circular stopper 33. The load-bearing disc 4 abuts against the circular stopper 33 during the assembly process, bearing part of the gravity of the cross beam 2 and the shear wall 3, and triggering the movement of components such as the concentric rod 24 through its own position change and force transmission, thereby promoting the progress of the entire assembly process; Four groups of equally spaced arc-shaped clamping grooves 32 are arranged on the inner ring surface of the circular groove 31. A number of equally spaced arc-shaped clamping plates 47 are fixedly arranged on the outer side face of the arc-shaped outer expansion plate 44. Each arc-shaped clamping plate 47 is slidably clamped in the corresponding arc-shaped clamping groove 32. The arc-shaped clamping plates 47 are clamped in the arc-shaped clamping grooves 32 while the arc-shaped outer expansion plates 44 expand, realizing the clamping and fixing of the cross beam 2 and the shear wall 3, and it is one of the key components to ensure the firm assembly of the structure.

[0019] Embodiment 3: On the basis of Embodiment 2, this embodiment further includes: In the specific implementation process, such as Figure 2 andFigure 4 As shown in the figure, a fixing hole penetratingly distributed is formed in the middle of the fixing plate 1. Four arc-shaped through holes 16 circularly distributed around the fixing hole are formed in the middle of the fixing plate 1. A fixing shaft 11 penetratingly distributed is rotatably inserted into the interior of the fixing hole. The fixing shaft 11 provides rotational support for the gear disk 12, enabling the gear disk 12 to rotate stably around it, ensuring the movement track and stability of the gear disk 12, and being the basic support component for the normal operation of the gear disk 12; A driven gear 18 concentrically and fixedly connected is sleeved on the middle part of each driven shaft 17. A pair of gear disks 12 concentrically and fixedly connected are sleeved on the front and rear ends of the fixing shaft 11. Each gear disk 12 is meshed and connected with the four driven gears 18 on the same side. By synchronously rotating the pair of gear disks 12 to rotate along the fixing shaft 11, through the meshing action with the driven gears 18, the driven shafts 17 and the wire wheels 19 are driven to rotate, thereby realizing the tightening of the fixing wire 110. It is one of the power components for driving the movement of the fixing wire 110. The driven gear 18 is meshed with the gear disk 12, transmitting the rotation of the gear disk 12 to the driven shaft 17, and the driven shaft 17 drives the wire wheel 19 to rotate, further realizing the tightening of the fixing wire 110. It is the intermediate transmission component for transmitting the power of the gear disk 12 to the fixing wire 110; A number of uniformly distributed flange holes are formed in each gear disk 12. The flange holes and the arc-shaped through holes 16 provide a penetrating channel for the double-headed lead screw 13, enabling the double-headed lead screw 13 to pass through the relevant components smoothly, realizing the limit fixation of the gear disk 12, and being an important connection hole position for ensuring the assembly and fixation of the whole structure. A double-headed lead screw 13 penetratingly distributed is inserted into each arc-shaped through hole 16. The two ends of each double-headed lead screw 13 are penetratingly inserted into the corresponding flange holes. The double-headed lead screw 13 is penetratingly inserted into the corresponding flange holes and arc-shaped through holes 16, and its two ends are locked by self-locking nuts, realizing the limit fixation of the pair of gear disks 12, preventing them from rotating back to their original positions, ensuring that the tightening state of the fixing wire 110 is maintained, thereby ensuring the fixing effect between the fixing plate 1 and the cross beam 2, and being an important limit component for maintaining the fixed state of the structure. And self-locking nuts with threaded locking are sleeved on the two ends of each double-headed lead screw 13. The self-locking nuts cooperate with the double-headed lead screw 13 to lock the two ends of the double-headed lead screw 13, preventing the double-headed lead screw 13 from loosening, thereby realizing the effective limit fixation of the gear disk 12, ensuring that the whole structure will not lose stability due to the rotation and reset of the gear disk 12 after being fixed; At both ends of the crossbeam 2, driven pin shafts 23 are fixedly installed at the corners of the end faces. At the corners of the four side faces of the fixed plate 1, fixed pin shafts 14 are fixedly installed. At the outer end of each fixed pin shaft 14, a buffer spring 15 is sleeved. At the outer end of each buffer spring 15, it is sleeved on the driven pin shaft 23 on the corresponding side. The buffer spring 15 can effectively transfer and balance the force between the crossbeam 2 and the fixed plate 1. When the crossbeam 2 is subjected to an external force, the buffer spring 15 will transfer part of the force to the fixed plate 1, and at the same time, it will adjust and distribute the force according to its own elastic characteristics, making the force on the entire structure more uniform and avoiding structural damage caused by excessive local stress.

[0020] Specifically, the working principle and operation method of the present invention are as follows: Step 1, assemble and install a fixed plate 1, four crossbeams 2, and four shear walls 3 as Figure 1 shown. The concentric rod 24 and the hollow sleeve 41 are inserted into the corresponding circular grooves 31, so that the load-bearing disc 4 abuts against the circular stopper 33. Due to the gravity and mutual extrusion of the crossbeam 2 and the shear wall 3, the concentric rod 24 is driven to slide along the hollow sleeve 41, and then the positioning pin shaft 26 is driven to slide along the U-shaped opening 43, and then the tension spring 27 is driven to be compressed and deformed. Step 2, at the same time, the distance between the first rectangular collar 25 and the second rectangular collar 42 decreases. Under the cross-hinged action of the first connecting rod 28 and the second connecting rod 210, the limit pin shaft 29 is driven to slide along the elliptical pin hole, and the arc-shaped outward expansion plate 44 is driven to expand outward along the concentric rod 24 and the hollow sleeve 41 and abut against the inner wall of the circular groove 31, and the arc-shaped clamping plate 47 is driven to be clamped in the arc-shaped clamping groove 32, thereby realizing the assembly and clamping fixation of the crossbeam 2 and the shear wall 3. Step 3, wind the outer end of the fixed wire 110 in a triangular shape around the corresponding pair of fixed anchor bolts 22. Synchronously rotate a pair of gear discs 12 to rotate along the fixed shaft 11. The gear discs 12 are meshed to drive the driven gear 18, the driven shaft 17, and the wire wheel 19 to rotate. The wire wheel 19 drives the fixed wire 110 to tighten, and drives the fixed plate 1 and the four crossbeams 2 to be fixedly locked with each other. Immediately insert the double-headed lead screw 13 through the corresponding flange holes and arc-shaped through holes 16, and then lock the two ends of the double-headed lead screw 13 with self-locking nuts to realize the limit fixation of a pair of gear discs 12 and prevent them from rotating back to their original positions.

[0021] The present invention utilizes gravity to realize the automatic movement of components and simplifies the assembly process; the cooperation of the concentric rod 24, the hollow sleeve 41, etc. provides buffer resilience to ensure the stability of the structure; the rectangular collars, etc. cooperate to make the crossbeam 2 and the shear wall 3 tightly clamped, improving the strength; the winding of the fixed wire 110 and the rotation of the gear discs 12 realize precise fixation, and the limit of the double-headed lead screw 13 ensures long-term stability. The operation is simple, safe and reliable.
