[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Example 1: This example provides a stirrup-assembled shear wall structure, see Figure 1-8, specifically, it includes a fixed plate 1. The four diagonal corners of the fixed plate 1 are all chamfered. Shear walls 3 are provided in the four diagonal directions of the fixed 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 fixed plate 1 and the four cross beams 2 are distributed in a "cross" shape. The fixed plate 1 serves as the basic fixing component of the entire structure. Through connection and fixation with the cross beam 2, it provides support and positioning reference for the entire device;

[0039] 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 effect 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 is assembled and clamped with the shear wall 3 to jointly form a stable structural framework;

[0040] 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 blocks 33, arc-shaped chutes 32 and other structures interact with components such as the concentric rod 24, load-bearing plate 4, arc-shaped clamping plate 47, etc. to achieve assembly and clamping fixation with the cross beam 2 and ensure the integrity of the structure;

[0041] A number of equally spaced circular grooves 31 are provided on the four side surfaces of the shear wall 3. A number of equally spaced concentric discs 21 are fixedly provided on the two side surfaces of the cross beam 2. A 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;

[0042] The concentric rod 24 slides along the hollow sleeve 41 under the gravity and mutual extrusion of the cross beam 2 and the shear wall 3, 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 achieve further fixation of the cross beam 2 and the shear wall 3;

[0043] 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 and the concentric rod 24 jointly provide support and guidance for the arc-shaped outer expansion plate 44 to ensure that it can accurately abut against the inner wall of the circular groove 31 to achieve the assembly and fixation of the structure;

[0044] At both ends of the cross beam 2, there are two pairs of fixedly arranged fixing anchor bolts 22 that penetrate and are distributed. The fixing anchor bolts 22 are used to fix the outer ends of the fixing steel wires 110, provide an anchoring point for the fixing steel wires 110, and ensure that the fixing steel wires 110 can effectively connect the fixing plate 1 and the cross beam 2 together during the tightening process, guaranteeing the stability of the structure. On the middle parts of the side edges of the front and rear sides of the fixing plate 1, driven shafts 17 are rotatably inserted. A wire wheel 19 that is concentrically fixedly connected is sleeved on the outer end of each driven shaft 17. A fixing steel wire 110 is fixedly wound on each wire wheel 19;

[0045] The outer end of each fixing steel wire 110 is wound in a triangular shape, and the outer end of each fixing steel wire 110 is sleeved on the outer ends of a pair of fixing anchor bolts 22 on the same side. The outer end of the fixing steel wire 110 is wound in a triangular shape on the corresponding pair of fixing anchor bolts 22. The tightening is driven by the rotation of the wire wheel 19, thereby fixing and locking the fixing plate 1 and the four cross beams 2 to each other. It is an important component for realizing the connection and fixation between the fixing plate 1 and the cross beam 2. Through the coordinated action of components such as the fixing steel wire 110 and the gear disk 12, it is fixed and locked with the four cross beams 2 to ensure the stability of the entire structure.

[0046] Embodiment Two: On the basis of Embodiment One, this embodiment further includes:

[0047] 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. At the same time, to a certain extent, it maintains the connection and interaction between the components;

[0048] Four U-shaped openings 43 that are circularly distributed are formed on the outer ring surface of the hollow sleeve 41. Four positioning pins 26 that are circularly distributed 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;

[0049] A concentrically fixed first rectangular collar 25 is sleeved on the middle of the concentric rod 24. A first ear seat is fixed to the middle of each of the four side surfaces of the first rectangular collar 25. The outer end of each first ear seat is provided with a pair of movable hinged first connecting rods 28. 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 with the first connecting rod 28 and the second connecting rod 210, the limiting pin 29 is driven to slide along the elliptical pin hole, thereby triggering the movement of a series of subsequent components, realizing the assembly, engagement and fixation of the structure. It is an important connecting component for transmitting motion and force.

[0050] The outer end of the hollow sleeve 41 is sleeved with a concentrically fixed second rectangular collar 42, and the middle part of the four sides of the second rectangular collar 42 is fixed with a second ear seat, and the outer end of each second ear seat is provided with a pair of movable hinged second connecting rods 210. The pair of first connecting rods 28 and second connecting rods 210 located on the same side are distributed in an "X" shape and are coaxially movable hinged in the middle. The first connecting rod 28 and the second connecting rod 210 are cross-hinged to convert the change in the spacing between the first rectangular collar 25 and the second rectangular collar 42 into the sliding movement of the limit pin 29, thereby driving the movement of the arc-shaped outward expansion plate 44 and the arc-shaped clamping plate 47 to realize the assembly, clamping and fixing of the beam 2 and the shear wall 3. It is a key component for realizing motion transmission and conversion between components;

[0051] Four circularly distributed arc-shaped outward expansion plates 44 are provided on the outer side surfaces of the concentric rod 24 and the hollow sleeve 41. Single ear seats 46 and limit plates 45 are fixed to the inner ends of the arc-shaped outward expansion plates 44, and elliptical pin holes are opened on the limit plates 45. The arc-shaped outward expansion plates 44 are expanded outward along the concentric rod 24 and the hollow sleeve 41 and abut against the inner wall of the circular groove 31, thereby increasing the contact area and friction of the structure, further improving the stability and reliability of the assembly of the beam 2 and the shear wall 3, and playing a role in strengthening the fixation.

[0052] The outer end of each pair of second connecting rods 210 is movably hinged to the outer end of the single ear seat 46 on the same side. The outer end of each pair of first connecting rods 28 is hinged with a limit pin 29 distributed throughout, and the middle part of each limit pin 29 is slidably inserted into the elliptical pin hole on the same side. Driven by the first connecting rod 28 and the second connecting rod 210, the limit pin 29 slides along the elliptical pin hole, providing a limiting and guiding function for the entire movement process, ensuring that each component moves according to the predetermined trajectory and method, thereby achieving accurate assembly, engagement and fixation.

[0053] A circular stopper 33 is fixedly provided in the circular groove 31, and a bearing plate 4 is fixedly provided at the outer end of the hollow sleeve 41. The bearing plate 4 abuts against the circular stopper 33. During the assembly process, the bearing plate 4 abuts against the circular stopper 33, bearing part of the gravity of the beam 2 and the shear wall 3. Through its own position change and force transmission, the bearing plate 4 triggers the movement of the concentric rod 24 and other components, thereby promoting the progress of the entire assembly process.

[0054] Four groups of equally spaced arc-shaped slots 32 are provided on the inner annular surface of the circular groove 31, and a number of equally spaced arc-shaped clips 47 are fixed on the outer side surface of the arc-shaped outward expansion plate 44. Each arc-shaped clip 47 is slidably engaged in the corresponding arc-shaped slot 32. When the arc-shaped outward expansion plate 44 is unfolded, the arc-shaped clip 47 is engaged in the arc-shaped slot 32, thereby realizing the engagement and fixation of the beam 2 and the shear wall 3. It is one of the key components to ensure the firm assembly of the structure.

[0055] Example 3: Based on Example 2, this example also includes:

[0056] In the specific implementation process, Figure 2 and Figure 4 As shown, a fixing hole is provided in the middle of the fixing plate 1 and four arc-shaped through holes 16 are provided in the middle of the fixing plate 1 and are distributed in a circle around the fixing hole. A fixing shaft 11 is inserted into the fixing hole and is distributed therethrough. The fixing shaft 11 provides rotational support for the gear plate 12, so that the gear plate 12 can rotate stably around it, ensuring the motion trajectory and stability of the gear plate 12. It is a basic supporting component for the normal operation of the gear plate 12.

[0057] The middle part of each driven shaft 17 is sleeved with a concentrically fixed driven gear 18, and the front and rear ends of the fixed shaft 11 are sleeved with a pair of concentrically fixed gear plates 12. Each gear plate 12 is meshed and connected with the four driven gears 18 on the same side, and the pair of gear plates 12 rotate synchronously along the fixed shaft 11. Through the meshing action with the driven gear 18, the driven shaft 17 and the wire wheel 19 are driven to rotate, thereby realizing the tightening of the fixed steel wire 110. It is one of the power components that drives the fixed steel wire 110 to move. The driven gear 18 meshes with the gear plate 12, and transmits the rotation of the gear plate 12 to the driven shaft 17. The driven shaft 17 drives the wire wheel 19 to rotate, thereby realizing the tightening of the fixed steel wire 110. It is an intermediate transmission component that transmits the power of the gear plate 12 to the fixed steel wire 110.

[0058] Each gear plate 12 is provided with a number of evenly distributed flange holes. The flange holes and the arc-shaped through holes 16 provide through-channels for the double-ended screw 13, so that the double-ended screw 13 can smoothly pass through the relevant components to achieve the limited fixation of the gear plate 12. It is an important connection hole to ensure the assembly and fixation of the entire structure. A through-distributed double-ended screw 13 is inserted in each arc-shaped through hole 16. The two ends of each double-ended screw 13 are inserted through the corresponding flange holes. The double-ended screw 13 is inserted through the corresponding flange holes and the arc-shaped through holes 16, and its two ends are locked by self-locking nuts. The limit fixation of a pair of gear plates 12 is realized to prevent them from rotating and resetting, and to ensure that the tightening state of the fixing wire 110 is maintained, thereby ensuring the fixing effect of the fixing plate 1 and the crossbeam 2. It is an important limit component for maintaining the fixed state of the structure, and both ends of each double-headed screw 13 are sleeved with self-locking nuts with threaded locking. The self-locking nuts cooperate with the double-headed screw 13 to lock the two ends of the double-headed screw 13 to prevent the double-headed screw 13 from loosening, thereby achieving effective limit fixation of the gear plate 12, ensuring that the entire structure will not lose stability due to the rotation and resetting of the gear plate 12 after being fixed;

[0059] Follower pins 23 are fixed at the corners of both end faces of the crossbeam 2, and fixed pins 14 are fixed at the four side corners of the fixed plate 1. The outer end of each fixed pin 14 is sleeved with a buffer spring 15, and the outer end of each buffer spring 15 is sleeved on the follower pin 23 on the corresponding side; the buffer spring 15 can effectively transmit and balance the force between the crossbeam 2 and the fixed plate 1. When the crossbeam 2 is subjected to external force, the buffer spring 15 will transmit part of the force to the fixed plate 1, and will also adjust and distribute the force according to its own elastic characteristics, so that the force of the entire structure is more uniform, avoiding local excessive stress and causing structural damage.

[0060] Specifically, the working principle and operation method of the present invention are as follows:

[0061] Step 1: Place a fixed plate 1, four beams 2, and four shear walls 3 as shown in the following example: Figure 1 As shown in the figure, the concentric rod 24 and the hollow sleeve 41 are inserted into the corresponding circular groove 31, so that the bearing plate 4 rests on the circular stopper 33. Due to the gravity and mutual extrusion of the beam 2 and the shear wall 3, the concentric rod 24 is driven to slide along the hollow sleeve 41, thereby driving the positioning pin 26 to slide along the U-shaped opening 43, thereby driving the tension spring 27 to be compressed and deformed;

[0062] Step 2: Meanwhile, 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 clamping and fixing of the cross beam 2 and the shear wall 3;

[0063] Step 3: Wind the outer end of the fixing wire 110 in a triangular shape around a corresponding pair of fixing anchor bolts 22. Synchronously rotate a pair of gear disks 12 to rotate along the fixed shaft 11. The gear disks 12 are engaged to drive the driven gear 18, the driven shaft 17, and the wire wheel 19 to rotate. The wire wheel 19 drives the fixing wire 110 to tighten, and drives the fixing plate 1 to be fixedly locked with the four cross beams 2;

[0064] 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 disks 12 and prevent them from rotating back to their original positions.

[0065] The present invention utilizes gravity to realize the automatic action 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 structural stability; the rectangular collars, etc. cooperate to tightly clamp the cross beam 2 and the shear wall 3 to improve the strength; the winding of the fixing wire 110 and the rotation of the gear disks 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.

[0066] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
