Description

Technical Field

[0001] This invention relates to the field of prefabricated component connection structure technology, specifically to a seismic-resistant prefabricated shear wall structure and method that can be quickly connected. Background Technology

[0002] In the construction field, especially in the design of high-rise buildings, reinforced concrete shear walls are widely used due to their excellent in-plane stiffness and load-bearing capacity. However, traditional cast-in-place construction methods have many limitations, including high resource consumption and serious environmental pollution. In contrast, prefabricated assembly structures can significantly reduce construction waste, reduce noise pollution at construction sites, and improve project quality. Among them, prefabricated steel-concrete shear walls are a high-performance composite shear wall form that fully utilizes the advantages of both concrete and steel through the effective synergy of the two materials, thereby enhancing the overall load-bearing capacity of the structure.

[0003] Currently, the common connection method for prefabricated concrete shear wall panels involves creating a vertical joint between two shear walls, and then connecting them by placing ring-shaped and vertical reinforcing bars within the joint before pouring concrete. In this method, the ring-shaped reinforcing bars need to be pre-placed at the vertical joint and secured with wire. Subsequently, the vertical reinforcing bars are inserted into the square area formed by the ring-shaped reinforcing bars, requiring wire and supporting formwork for positioning. Finally, concrete is poured to connect the vertical joint into a single unit. This method is not only structurally complex and cumbersome to construct, but it also reduces the hysteretic performance and seismic resistance of the assembled shear wall.

[0004] To overcome these shortcomings, existing technical solutions propose an improved connection mechanism, such as the prefabricated shear wall connection mechanism and its construction method disclosed in Chinese Patent Publication No. CN113775078A. This solution pre-embeds specific anchors and steel anchor rings within the prefabricated shear wall, allowing the connection to be completed simply by passing the circular cross-section steel bars through the central hole of the steel anchor ring during installation. This eliminates the need for additional binding work, simplifying the construction steps and improving construction efficiency.

[0005] While the above solution offers some convenience, it still has several limitations. First, it requires specially designed steel anchor rings and anchors, increasing costs. Second, to ensure successful insertion of the circular section reinforcement, the steel anchor rings between adjacent shear walls must be precisely aligned. However, in actual construction, due to various factors, there is often a certain degree of positional deviation between adjacent shear walls, and the existing structure is difficult to accommodate these deviations, affecting the accurate connection of the circular section reinforcement. Summary of the Invention

[0006] Therefore, the purpose of this invention is to provide a seismic-resistant prefabricated shear wall structure and method that can be quickly connected, in order to solve the existing problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A seismic-resistant prefabricated shear wall structure that can be quickly connected includes: The first and second shear walls are spaced apart, and each of the two shear walls has several sets of pre-embedded reinforcement bars spaced from top to bottom on the opposite side. Several sets of first and second connectors, both types of connectors are covered outside the embedded bars of the corresponding side shear wall, and the two types of connectors are interlocked. Several vertical ribs pass through the first connector and the second connector from top to bottom, and are used to connect the first shear wall and the second shear wall into a whole; The elastic sleeve, installed between the embedded reinforcement and the connector, is used to buffer the interaction force between two adjacent shear walls and enhance the seismic resistance of the shear wall.

[0008] Preferably, the first connector includes a first base plate, first overlapping edges respectively disposed on the upper ends of both sides of the first base plate, and a first connecting edge extending horizontally outward along the first base plate; the ends of the two first overlapping edges away from the first base plate extend towards the center to form a first overlapping edge that can be movably overlapped with the pre-embedded reinforcement; the first connecting edge and the first base plate are provided with a plurality of first connecting holes that cooperate with the vertical reinforcement. Preferably, the second connector includes a second base plate, second overlapping edges respectively disposed at the lower ends of both sides of the second base plate, and a second connecting edge extending horizontally outward along the second base plate; the ends of the two second overlapping edges away from the second base plate extend towards the center to form a second overlapping edge that can be movably overlapped with the pre-embedded reinforcement, and the second connecting edge and the second base plate are provided with a plurality of second connecting holes that are one-to-one opposite to the first connecting holes.

[0009] Preferably, the two first lap edges are curved in an arc shape that is adapted to the cross-section of the embedded bar, and the two first lap edges extend horizontally toward the side that is close to each other to form a pair of first limiting plates, and the distance between the two first limiting plates is adapted to the width of the second connecting edge. The two second lap edges are curved in an arc shape that is adapted to the cross-section of the embedded reinforcement, and the bottom of the two second lap edges extends horizontally toward the side that is close to each other to form a pair of second limiting plates. The distance between the two second limiting plates is adapted to the width of the first connecting edge.

[0010] By adopting the above technical solution, the gap between the two first limiting plates is just enough to allow the second connecting edge to be inserted, and the gap between the two second limiting plates is just enough to allow the first connecting edge to be inserted. This design ensures the precise alignment of the first connecting piece and the second connecting piece in the vertical gap, which facilitates the positioning of the first connecting hole and the second connecting hole and the subsequent insertion process of the vertical rib.

[0011] Preferably, the bottom of the first lap edge and the second lap edge are semi-circular structures to restrict the vertical movement of the embedded reinforcement when it is connected to the first connector or the second connector, so as to ensure the stability of the first connector and the second connector when the first shear wall and the second shear wall are connected.

[0012] The inner diameter of the arc formed by the first lap edge and the second lap edge is greater than the outer diameter of the embedded bar, but less than 1.5 times the outer diameter of the embedded bar.

[0013] Preferably, each circumferential side surface of the lap joint is provided with several welding grooves that penetrate the side wall of the lap joint, and the welding grooves extend in a direction parallel to the pre-embedded reinforcement.

[0014] Preferably, at least one set of positioning members is provided between each set of first and second connecting members. The positioning members are provided with multiple sets of vertical insertion holes at intervals. The vertical ribs pass through the first connecting member, the insertion holes and the second connecting member in sequence to connect the two shear walls into a whole.

[0015] Preferably, the outer wall of the elastic sleeve is provided with friction texture, and the side wall of the elastic sleeve is provided with multiple arc-shaped grooves along the length direction of the pre-embedded reinforcement. The arc-shaped grooves penetrate the side wall of the elastic sleeve, and the positions of the arc-shaped grooves correspond to those of the welding grooves.

[0016] Preferably, after the first connector and the second connector are joined together, a shock-absorbing kit is also provided on the outside. The shock-absorbing kit is sleeved on the outside of the first connector and the second connector and is an extendable foldable structure. The upper and lower sides of the shock-absorbing kit are provided with through holes for the vertical ribs to pass through. The shock absorption kit comprises a three-layer structure: an inner layer, a middle layer, and an outer layer. The inner and outer layers are made of polyurethane and have friction textures on their inner walls. The middle layer is a spring assembly, which includes two side support plates and a spring fixed inside the support plates.

[0017] The present invention also discloses a construction method for the above-described shear wall structure, comprising the following steps: Step 1: Overlap the first connector and the second connector onto the corresponding embedded bars of the two walls respectively; Step 2: Pre-position the first connector and place it into the first insertion groove on the upper surface of the first base plate, so that the second insertion groove on the lower surface of the second base plate is aligned with the upper end of the connector. With the assistance of the connector, the first and second connecting holes are accurately aligned. After their positions are fixed, the first and second connectors are welded and fixed to the corresponding embedded ribs through the first and second welding grooves, thus completing the accurate alignment of the first and second connectors. Step 3: Weld and fix the first and second connectors to the pre-embedded bars at different heights, and make the vertical bars pass through the first and second connectors to complete the connection between the first and second shear walls. Then, the formwork can be erected, mortar can be poured in and cast to shape, and the rapid connection between the first and second shear walls can be completed.

[0018] By adopting the above technical solution, the first and second connectors are aligned and welded to the pre-embedded reinforcing bars in the vertical joint between the first and second shear walls. The vertical reinforcing bars pass sequentially through the first and second connectors at different heights. Compared to the original connection method, this significantly simplifies the construction process. Only the first and second connectors need to be welded and fixed, eliminating the need for extensive reinforcement binding or the use of custom components, thus greatly reducing the difficulty and cost of connecting adjacent shear walls. Furthermore, the adjustable first and second connectors allow for positional deviations between adjacent shear walls within a certain range, ensuring accurate and flexible connections even when positional deviations exist during actual construction.

[0019] The present invention is further configured such that a first arc-shaped guide edge is symmetrically provided on the edge of the two first limiting plates and on the side close to the first connecting edge, and a second arc-shaped connecting edge adapted to the first arc-shaped guide edge is formed between the two sides of the second connecting edge and the second bottom plate; The edges of the two second limiting plates are symmetrically provided with second arc-shaped guide edges on the side close to the second connecting edge, and a first arc-shaped connecting edge is formed between the two sides of the first connecting edge and the first base plate, which is adapted to the second arc-shaped guide edge.

[0020] By adopting the above technical solution, the matching design of the first arc-shaped guide edge and the second arc-shaped connecting edge, as well as the second arc-shaped guide edge and the first arc-shaped connecting edge, helps to ensure the precise alignment between the first connector and the second connector. At the same time, these arc-shaped guide edges can also guide the correct installation of the two connectors, simplify the construction process, and improve construction efficiency.

[0021] The present invention is further configured such that the first connecting hole is circular in shape to match the cross-section of the vertical rib, and a plurality of first connecting holes are distributed overlappingly along a straight line to form spaced first vertical rib placement positions; The second connecting hole is circular in shape to match the cross-section of the vertical rib, and several second connecting holes are distributed overlappingly along a straight line to form spaced second vertical rib placement positions; Among them, the straight lines containing a number of first connecting holes and second connecting holes coincide with the center lines of the length direction of the first base plate and the second base plate.

[0022] By adopting the above technical solution, the distribution of the first connecting hole and the second connecting hole forms an alternately distributed first vertical rib placement position and second vertical rib placement position, ensuring that the vertical rib can be accurately aligned between the first connector and the second connector, thereby realizing the rapid installation and fixing of the vertical rib.

[0023] The present invention is further configured such that the number of the first connecting holes is 2N+1, where N=2, 3, or 4, and each first connecting hole is a first vertical rib placement position. The number of the second connecting holes and the number of the second vertical rib placement positions are the same as the number of the first connecting holes and the first vertical rib placement positions.

[0024] By adopting the above technical solution, the number and distribution of the first and second connecting holes ensure that the vertical bars can be accurately aligned and inserted along the first and second connecting parts, thereby realizing the rapid installation and fixing of the vertical bars. Increasing the number of the first and second connecting holes and the vertical bars can further enhance the connection strength between shear walls and further improve the overall structure and seismic performance.

[0025] The present invention is further configured such that a first insertion groove similar in shape to the overlapping shape of the first connecting holes and relatively enlarged is formed on the outer periphery of the plurality of first connecting holes and on the upper end surface of the first base plate; a second insertion groove similar in shape to the overlapping shape of the plurality of second connecting holes and relatively enlarged is formed on the outer periphery of the plurality of second connecting holes and on the lower end surface of the second base plate; a positioning member is fitted between the first insertion groove and the second insertion groove; the shape of the positioning member is adapted to the first insertion groove and the second insertion groove, and an insertion hole with the same overlapping shape as the plurality of first connecting holes is formed on its inner side.

[0026] By adopting the above technical solution, the design of the first and second insertion slots, along with the use of the positioning component, ensures precise alignment between the first and second connectors. Simultaneously, the shape of the insertion hole inside the positioning component matches the shape of the first connection hole, allowing the vertical rib to be quickly and accurately inserted into place. This structure ensures the accuracy of the connection between the first and second connectors and the stability of the structure. Welding and fixing are only performed after precise alignment, thereby enhancing the overall seismic performance of the structure.

[0027] The present invention is further configured such that the first overlap is curved and a plurality of first welding grooves are provided around its peripheral surface, and the plurality of first welding grooves are distributed in a direction parallel to the pre-embedded reinforcement. Both the second lap edge and the second lap side have arc-shaped bends, and the outer walls of the second lap edge and the second lap side are provided with a plurality of second welding grooves through the arc-shaped bends. The plurality of second welding grooves are distributed in a direction parallel to the embedded reinforcement.

[0028] By adopting the above technical solution, the first and second welding grooves can further facilitate the welding and fixing of the first and second lap edges with the embedded reinforcement, and can obtain a larger contact area, thereby improving the connection strength and structural stability. This structure not only simplifies the construction process and improves construction efficiency, but also ensures the accuracy of the connection and the stability of the structure, thus enhancing the overall seismic performance of the structure.

[0029] The present invention is further configured such that both the first welding groove and the second welding groove are linearly distributed.

[0030] By adopting the above technical solution, the linear distribution design of the first and second welding grooves ensures that the first and second lap edges can obtain a larger contact area when they are welded and fixed with the embedded reinforcement, thereby improving the connection strength and structural stability.

[0031] The present invention is further configured such that the first connector and the second connector are formed by cutting and integrally bending a plate-shaped steel sheet.

[0032] By adopting the above technical solution, the first connector and the second connector are constructed by cutting and bending plate-shaped steel sheets in one piece, which not only simplifies the manufacturing process and reduces production costs, but also ensures the structural strength and stability of the connector.

[0033] The present invention is further configured such that the extension length of the first base plate and the second base plate is L1, and the extension length of the first connecting edge and the second connecting edge is L2, where L1=L2; An elastic sleeve is fitted around the pre-embedded reinforcement bar, the size of which matches the size of the pre-embedded reinforcement bar. The inner wall of the elastic sleeve is fixedly connected to the pre-embedded reinforcement bar, and the outer wall is provided with friction texture to enhance the seismic resistance of the shear wall. An arc-shaped groove is provided along the length of the pre-embedded reinforcement bar, and the arc-shaped groove corresponds to the positions of the first welding groove and the second welding groove, respectively, to facilitate the welding of the pre-embedded reinforcement bar to the first connector and the second connector. The thickness of the elastic sleeve is 1 / 4 to 1 / 3 of the radius of the pre-embedded reinforcement bar.

[0034] After the first and second connectors are joined, a shock-absorbing kit is provided horizontally. The shock-absorbing kit is sleeved on the outside of the first and second connectors and has a folded structure. A bending groove is provided at the position corresponding to the edge of the first and second connectors. The bending groove is used to match and fix the shock-absorbing kit to the first and second connectors. Velcro is provided on both sides of the shock-absorbing kit. The Velcro is used to tightly fix the shock-absorbing kit to the first and second connectors to enhance the shock absorption effect of the connection structure. Hollow grooves are provided on the upper and lower sides of the shock-absorbing kit to avoid affecting the insertion and fixation of the vertical ribs.

[0035] The shock absorption kit includes a three-layer structure: an inner layer, a middle layer, and an outer layer. The inner and outer layers are made of polyurethane and have friction textures on their inner walls. The middle layer is a spring assembly, which is fixedly connected to the inner and outer layers on both sides to improve the shock absorption effect. The spring assembly includes two support plates on both sides and a spring fixed inside the support plates.

[0036] By adopting the above technical solution, the extension lengths of the first base plate and the second base plate are equal to the extension lengths of the first connecting edge and the second connecting edge, which ensures the symmetry and stability of the connectors during installation and helps to improve the alignment accuracy between the connectors.

[0037] In summary, the present invention has the following main beneficial effects: This invention simplifies the construction process by using a first and second connector to align and weld with the embedded reinforcing bars, and by having the vertical reinforcing bars pass through these connectors. This eliminates the need for extensive rebar tying or the use of custom-made components, reducing connection difficulty and cost. Furthermore, the adjustable first and second connectors allow for a certain range of positional deviation, ensuring connection accuracy and flexibility, thereby improving the overall integrity and seismic performance of the structure.

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0041] The embodiments of the present invention will now be described.

[0042] This invention discloses a seismic-resistant prefabricated shear wall structure that can be quickly connected, such as... Figure 1-13 As shown, the first shear wall 10 and the second shear wall 20 are spaced apart, and a vertical joint 30 is formed between the first shear wall 10 and the second shear wall 20. The first shear wall 10 and the second shear wall 20 are respectively provided with a number of pairs of embedded bars 40 facing the vertical joint 30. Each pair of embedded bars 40 includes two rod-shaped embedded bars 40 that are parallel to each other along the same horizontal plane. The number of pairs of embedded bars 40 are arranged at equal intervals along the extension direction of the vertical joint 30. The first connector 50 is a sheet metal bending structure with an opening at the top, specifically including a horizontal first base plate 51, a first overlapping edge 52 that is bent vertically upward along both sides of the first base plate 51, and a first connecting edge 53 that extends horizontally outward along the first base plate 51. The first overlapping edge 52 forms an arc-shaped first overlapping edge 521 that can movably overlap with the embedded rib 40. A plurality of first connecting holes 54 are provided through the first connecting edge 53 and the first base plate 51. The two first overlapping edges 521 are arc-shaped bends adapted to the cross-section of the embedded rib 40, and the two first overlapping edges 521 extend horizontally toward the side that is close to each other to form a pair of first limiting plates 55. The distance between the two first limiting plates 55 is adapted to the width of the second connecting edge 63.

[0043] The sheet metal bending structure with an opening at the lower part of the second connector 60 includes a horizontal second base plate 61, second overlapping edges 62 bent vertically downwards along both sides of the second base plate 61, and a second connecting edge 63 extending horizontally outwards along the second base plate 61. A second overlapping edge 621, which can movably overlap with the embedded rib 40, is formed between the second overlapping edge 62 and the base plate. A plurality of second connecting holes 64, corresponding one-to-one with the first connecting holes 54, are provided between the second connecting edge 63 and the second base plate 61. The two second overlapping edges 621 are curved and bent in an arc shape adapted to the cross-section of the embedded rib 40. The bottom of the second overlapping edge 62 extends horizontally toward the side that is close to each other to form a pair of second limiting plates 65. The distance between the two second limiting plates 65 is adapted to the width of the first connecting edge 53. The gap between the two first limiting plates 55 is just enough for the second connecting edge 63 to be inserted, and the gap between the two second limiting plates 65 is just enough for the first connecting edge 53 to be inserted. This design ensures the precise alignment of the first connecting piece 50 and the second connecting piece 60 in the vertical groove 30, which facilitates the positioning of the first connecting hole 54 and the second connecting hole 64 and the subsequent insertion process of the vertical rib 70.

[0044] The first lap edge 521 and the second lap edge 621 are welded and fixed to the embedded reinforcement 40. The first lap edge 521 is curved and has several first welding grooves 59 extending through its circumferential surface. The first welding grooves 59 are distributed in a direction parallel to the embedded reinforcement 40. Both the first welding grooves 59 and the second welding grooves 69 are linearly distributed. This linear distribution design ensures that the first lap edge 521 and the second lap edge 621 can obtain a larger contact area when welded and fixed to the embedded reinforcement 40, thereby improving the connection strength and structural stability.

[0045] The bottom of the first lap edge 521 and the second lap edge 621 are semi-circular structures, which are used to restrict the vertical movement of the embedded bar 40 when it is connected to the first connector 50 and the second connector 60, so as to ensure the stability of the first connector 50 and the second connector 60 when the first shear wall 10 and the second shear wall 20 are connected; the inner diameter of the arc formed by the first lap edge 521 and the second lap edge 621 is larger than the outer diameter of the embedded bar, and smaller than 1.5 times the outer diameter of the embedded bar 40.

[0046] By using the first connector 50 and the second connector 60 to be aligned and welded to the pre-embedded reinforcing bars 40 in the vertical joint 30 between the first shear wall 10 and the second shear wall 20, and by having the vertical reinforcing bars 70 pass sequentially through the first connector 50 and the second connector 60 at different heights, the construction process is significantly simplified compared to the original connection method. Only the first connector 50 and the second connector 60 need to be welded and fixed, eliminating the need for extensive binding of reinforcing bars or the use of custom components, thereby greatly reducing the difficulty and cost of connecting adjacent shear walls. In addition, the adjustable positions of the first connector 50 and the second connector 60 allow for positional deviations of adjacent shear walls within a certain range, ensuring accurate and flexible connections even when positional deviations exist in actual construction.

[0047] The first connector 50 and the second connector 60 are constructed by cutting and bending plate-shaped steel sheets in one piece, which not only simplifies the manufacturing process and reduces production costs, but also ensures the structural strength and stability of the connectors.

[0048] The edges of the two first limiting plates 55 and the side close to the first connecting edge 53 are symmetrically provided with first arc-shaped guide edges 56, and the two sides of the second connecting edge 63 form a second arc-shaped connecting edge 67 between the second base plate 61 and the first arc-shaped guide edge 56. The edges of the two second limiting plates 65 are symmetrically provided with second arc-shaped guide edges 66 on the side close to the second connecting edge 63. The two sides of the first connecting edge 53 form a first arc-shaped connecting edge 57 between the first base plate 51 and the first arc-shaped guide edge 66. The matching design of the first arc-shaped guide edge 56 and the second arc-shaped connecting edge 67, as well as the matching design of the second arc-shaped guide edge 66 and the first arc-shaped connecting edge 57, helps to ensure the precise alignment between the first connector 50 and the second connector 60. At the same time, these arc-shaped guide edges can also guide the correct installation of the two connectors, simplify the construction process, and improve construction efficiency.

[0049] The first connecting hole 54 is circular in shape to match the cross-section of the vertical rib 70, and a plurality of first connecting holes 54 are distributed overlappingly along a straight line to form spaced first vertical rib placement positions (not shown in the figure). The second connecting hole 64 is circular in shape to match the cross-section of the vertical rib 70, and a plurality of second connecting holes 64 are distributed overlappingly along a straight line to form spaced second vertical rib placement positions (not shown in the figure). Among them, the straight line where several first connecting holes 54 and second connecting holes 64 are located coincides with the center line of the length direction of the first base plate 51 and the second base plate 61. The distribution of the first connecting holes 54 and the second connecting holes 64 forms the first vertical rib placement position and the second vertical rib placement position with intervals, ensuring that the vertical rib 70 can be accurately aligned between the first connector 50 and the second connector 60, thereby realizing the rapid installation and fixing of the vertical rib 70.

[0050] The number of first connecting holes 54 is 2N+1, where N=2, 3, or 4. Each first connecting hole 54 is a first vertical reinforcement placement position. The number of second connecting holes 64 and the number of second vertical reinforcement placement positions are the same as those of the first connecting holes 54 and the first vertical reinforcement placement positions. The number and distribution of the first connecting holes 54 and the second connecting holes 64 ensure that the vertical reinforcement 70 can be accurately aligned and inserted along the line between the first connector 50 and the second connector 60. In this embodiment, N=3, that is, the number of first connecting holes 54 and second connecting holes 64 is 7, forming 4 first vertical reinforcement placement positions and 4 second vertical reinforcement placement positions, thereby realizing the rapid installation and fixing of the vertical reinforcement 70. Increasing the number of first connecting holes 54, second connecting holes 64, and vertical reinforcement 70 can further enhance the connection strength between shear walls and further improve the overall structure and seismic performance.

[0051] A first insertion groove 58, similar in shape to the overlapping shape of the first connecting holes 54 but relatively enlarged, is formed on the outer periphery of the first connecting holes 54 and on the upper end surface of the first base plate 51. A second insertion groove 68, similar in shape to the overlapping shape of the second connecting holes 64 but relatively enlarged, is formed on the outer periphery of the second connecting holes 64 and on the lower end surface of the second base plate 61. A positioning member 80 is fitted between the first insertion groove 58 and the second insertion groove 68. The shape of the positioning member 80 is adapted to the first insertion groove 58 and the second insertion groove 68, and its inner side forms an insertion hole 81 with the same overlapping shape as the first connecting holes 54. The design of the first insertion groove 58 and the second insertion groove 68 and the use of the positioning member 80 ensure the precise alignment between the first connecting member 50 and the second connecting member 60. At the same time, the insertion hole 81 inside the positioning member 80 matches the shape of the first connecting hole 54, so that the vertical rib 70 can be quickly and accurately inserted into place. The aforementioned structure ensures the accuracy of the connection between the first connector 50 and the second connector 60 and the stability of the structure. Welding and fixing are only carried out after precise alignment, thereby enhancing the overall seismic performance of the structure. To further improve seismic performance, elastic abutment parts are provided at both the upper and lower ends of the positioning parts. These elastic abutment parts contact the rigid first base plate 51 and the second base plate 61, which can further buffer vibration impact.

[0052] Both the second lap edge 621 and the second lap side 62 have arc-shaped bends, and several second welding grooves 69 are provided around the arc-shaped bends of the outer walls of the second lap edge 621 and the second lap side 62. These second welding grooves 69 are distributed parallel to the embedded reinforcement 40. The first welding groove 59 and the second welding groove 69 further facilitate the welding and fixing of the first lap edge 521 and the second lap edge 621 to the embedded reinforcement 40, and achieve a larger contact area, thereby improving the connection strength and structural stability. This structure not only simplifies the construction process and improves construction efficiency, but also ensures the accuracy of the connection and the stability of the structure, thus enhancing the overall seismic performance of the structure.

[0053] The extension length of the first base plate 51 and the second base plate 61 is L1, and the extension length of the first connecting edge 53 and the second connecting edge 63 is L2. L1=L2. The extension length of the first base plate 51 and the second base plate 61 is equal to the extension length of the first connecting edge 53 and the second connecting edge 63, which ensures the symmetry and stability of the connector during installation and helps to improve the alignment accuracy between the connectors.

[0054] An elastic sleeve is fitted around the embedded reinforcement 40. The size of the elastic sleeve matches the size of the embedded reinforcement 40. Its inner wall is fixedly connected to the embedded reinforcement 40, and its outer wall is provided with friction texture to enhance the seismic resistance of the shear wall. An arc-shaped groove is provided along the length of the embedded reinforcement 40. The arc-shaped groove corresponds to the positions of the first welding groove 59 and the second welding groove 69, respectively, to facilitate the welding of the embedded reinforcement 40 to the first connector 50 and the second connector 60. The thickness of the elastic sleeve is 1 / 4 to 1 / 3 of the radius of the embedded reinforcement 40.

[0055] After the first connector 50 and the second connector 60 are joined, a shock-absorbing kit is also provided in the horizontal direction. The shock-absorbing kit is sleeved on the outside of the first connector 50 and the second connector 60. It has a folded structure and a bending groove is provided at the position corresponding to the edge of the first connector 50 and the second connector 60. The bending groove is used to match and fix the shock-absorbing kit with the first connector 50 and the second connector. Velcro is provided on both sides of the shock-absorbing kit. The Velcro is used to tightly fix the shock-absorbing kit with the first connector 50 and the second connector 60 to enhance the shock absorption effect of the connection structure. The upper and lower sides of the shock-absorbing kit are provided with slots to avoid affecting the insertion and fixation of the vertical rib 70.

[0056] The shock absorption kit consists of a three-layer structure: an inner layer, a middle layer, and an outer layer. The inner and outer layers are made of polyurethane and have friction textures on their inner walls. The middle layer is a spring assembly, which is fixedly connected to the inner and outer layers on both sides to improve the shock absorption effect. The spring assembly includes two support plates on both sides and springs fixed inside the support plates.

[0057] The specific construction process of this shear wall structure is as follows: First, within the vertical joint 30 between the first shear wall 10 and the second shear wall 20, locate two pairs of embedded reinforcing bars 40 at the same horizontal level. Take out a pair of first connectors 50 and second connectors 60. Overlap the first lap edge 521 of the first connector 50 and the second lap edge 621 of the second connector 60 onto the two pairs of embedded reinforcing bars 40 respectively. The semi-circular structure at the bottom of the first lap edge 521 and the second lap edge 621 restricts the movement of the embedded reinforcing bars 40. A shear wall 10 and a second shear wall 20; positioning members 80 are inserted into the first insertion grooves 58 and second insertion grooves 68 outside a plurality of first connecting holes 54 and second connecting holes 64. If the first connecting member 50 is pre-positioned, the positioning member 80 is placed into the first insertion groove 58 on the upper end face of the first base plate 51, and then the second connecting member 60 is placed on another pre-embedded reinforcement 40, so that the second insertion groove 68 on the lower end face of the second base plate 61 is aligned with the upper end of the positioning member 80, so that the plurality of first connecting holes 54 and second connecting holes 64 are aligned with the second insertion groove 68 on the lower end face of the second base plate 61, so that the plurality of first connecting holes 54 and second connecting holes 60 are aligned with the second insertion groove 68 on the lower end face of the second base plate 61, so that the ... With the assistance of the positioning member 80, the connecting hole 54 and the second connecting hole 64 are accurately aligned. After their positions are fixed, the first connecting member 50 and the second connecting member 60 are welded and fixed to the corresponding embedded reinforcement 40 through the first welding groove 59 and the second welding groove 69, respectively, thus completing the accurate alignment of the first connecting member 50 and the second connecting member 60. The shock-absorbing kit is fixed to the first connecting member 50 and the second connecting member 60 with Velcro. Then, the vertical reinforcement 70 can be inserted in sequence, so that it is located at the first vertical reinforcement placement position and the second vertical reinforcement placement position at intervals. Repeat the above process to weld and fix the first connecting member 50 and the second connecting member 60 to the embedded reinforcement 40 at different heights in the vertical joint 30, so that the vertical reinforcement 70 passes through each of the first connecting member 50 and the second connecting member 60, thus completing the connection between the first shear wall 10 and the second shear wall 20. Then, the formwork can be erected, mortar can be poured in for casting and shaping, thus completing the rapid connection between the first shear wall 10 and the second shear wall 20.

[0058] This invention simplifies the construction process by using a first connector 50 and a second connector 60 to be aligned and welded to the embedded reinforcing bars 40, with vertical reinforcing bars 70 passing through these connectors. This eliminates the need for extensive binding of reinforcing bars or the use of custom-made components, reducing connection difficulty and cost. Furthermore, the adjustable positions of the first connector 50 and the second connector 60 allow for a certain range of positional deviations, ensuring the accuracy and flexibility of the connection, thereby improving the overall integrity and seismic performance of the structure.
