Description

Technical Field

[0001] The present invention relates to the field of building structures, and particularly to a prefabricated butterfly-shaped shear wall-column system. Background Art

[0002] Compared with traditional shear walls, steel plate shear walls have lighter self-weight and better ductility, and the steel plate still has a large elastic lateral stiffness after buckling. Therefore, steel plate shear walls are widely used in the seismic design of high-rise buildings.

[0003] In the prior art, the walls and columns of prefabricated buildings are mostly designed separately. The seismic performance of traditional steel column structures is weak, and there are also problems such as insufficient bearing capacity and low flexural capacity, making it difficult to cooperate with steel plate shear walls. Therefore, it is necessary to improve and optimize them. Summary of the Invention

[0004] The present invention provides a prefabricated butterfly-shaped shear wall-column system to solve the problems of weak integrity of the wall-column system in prefabricated buildings in the prior art, resulting in insufficient synergy and weak seismic performance, and to achieve the purpose of enhancing the integrity of the wall-column system, improving the bearing capacity, flexural capacity and seismic capacity.

[0005] The present invention is realized by the following technical solutions:

[0006] A prefabricated butterfly-shaped shear wall-column system includes a steel plate shear wall component and a reinforced concrete column component. The reinforced concrete column component includes four bent plates surrounding a square, and high-ductility concrete is filled inside the four bent plates. A first T-shaped steel is clamped between two adjacent bent plates. The flange of the first T-shaped steel is fixed inside the high-ductility concrete, and the web of the first T-shaped steel extends outside the high-ductility concrete. The steel plate shear wall component is detachably connected to the web of the first T-shaped steel.

[0007] Aiming at the problems of weak integrity of the wall-column system in prefabricated buildings in the prior art, resulting in insufficient synergy and weak seismic performance, the present invention proposes a prefabricated butterfly-shaped shear wall-column system. This system forms a square structure surrounded by four bent plates, and high-ductility concrete is filled in this square structure to obtain a reinforced concrete column structure. Since a first T-shaped steel is clamped between any two adjacent bent plates, there are four first T-shaped steels in the reinforced concrete column component of this application. The four webs corresponding to the four first T-shaped steels extend outward in four directions respectively, so that the reinforced concrete column component of this application can be connected to the steel plate shear wall component in any one or more of the four directions as needed. In this application, the number of first T-shaped steels can be flexibly set according to the specific use scenario to control the number of corresponding shear walls, thereby improving the flexibility and versatility of prefabricated buildings.

[0008] This application uses a specific steel-concrete column assembly as the column structure of a prefabricated building. High-ductility concrete is filled into the space surrounded by four bent plates and solidified. Through the synergistic effect of the two materials, a significant improvement in bearing capacity is achieved. In addition, the four bent plates can be used as formwork, facilitating the pouring of concrete. This application uses the first T-shaped steel to connect the steel plate shear wall assembly and the steel-concrete column assembly, which can further improve the bearing capacity of the column structure, enhance its flexural stiffness, and at the same time enable the mechanical transfer between the wall and the column, improving the integrity of the wall-column system. In addition, the steel-concrete column assembly of this application can be used as both a load-bearing column and a damping column, and its hysteretic performance is significantly improved compared with that of ordinary concrete-filled steel tubes.

[0009] In addition, the high-ductility concrete used in this application is a professional term, namely Engineered Cementitious Composite (ECC) concrete. This application does not pursue the improvement of the formula / components of high-ductility concrete, and those skilled in the art can adopt existing mature formulas / components. This application creatively uses high-ductility concrete in the column structure of prefabricated buildings. When the column structure is subjected to seismic action, good ductility is generated by the bridging action of its internal fibers. Therefore, this application can significantly improve the seismic performance of the column structure in prefabricated buildings.

[0010] Further, the bent plate includes a first bent portion, a second bent portion, a third bent portion, and a fourth bent portion arranged vertically in sequence; the first bent portion and the third bent portion are located on the same side of the second bent portion, and the fourth bent portion and the second bent portion are located on the same side of the third bent portion; the lengths of the first bent portion and the fourth bent portion are equal, and the lengths of the second bent portion and the third bent portion are equal.

[0011] In this solution, the second bent portion and the third bent portion serve as the outer wall of the column structure. The first bent portion and the fourth bent portion are used to sandwich and connect with the web of the corresponding first T-shaped steel to achieve the connection between the first T-shaped steel and the bent plate; at the same time, the first bent portion and the fourth bent portion can also provide positioning for the flange, which is beneficial to quickly and accurately install the first T-shaped steel before pouring concrete. After pouring concrete, the first bent portion, the fourth bent portion, and the flange and part of the web of the first T-shaped steel are solidified in the concrete, and the bearing capacity and flexural stiffness of the column structure can be further improved through the structure of the bent plate.

[0012] Further, the four bending plates are fixedly covered at the top and bottom by hoop assemblies; the hoop assemblies include four bending strips; the bending strips include a fifth bending part, a sixth bending part, a seventh bending part, and an eighth bending part arranged vertically in sequence, the fifth bending part and the seventh bending part are respectively located on both sides of the sixth bending part, the sixth bending part and the eighth bending part are respectively located on both sides of the seventh bending part, the sixth bending part is attached to the outer wall of the second bending part, and the seventh bending part is attached to the outer wall of the third bending part; the fifth bending part and the eighth bending part are respectively attached to and bolted to the webs of two adjacent first T-shaped steels.

[0013] In this solution, the four bending plates are covered by hoop assemblies at both the top and bottom to improve the integrity of the column structure, ensure the stability during the concrete pouring process, and avoid the occurrence of the "elephant foot" phenomenon when the column structure is subjected to axial pressure. It should be noted that the structure of the hoop assembly in this solution not only adapts to the outer wall shape of the bending plate but also matches the web of the first T-shaped steel, so that a hoop assembly can be connected between the webs of two adjacent first T-shaped steels through bolts, thereby realizing the relative fixation between the hoop assembly and the bending plate.

[0014] Further, the steel plate shear wall assembly includes a first cross plate and a second cross plate distributed up and down, longitudinal plates hinged to the first cross plate and the second cross plate at both ends respectively, and a plurality of seismic components connected between the first cross plate and the second cross plate; one end of both the first cross plate and the second cross plate is fixedly connected to the web of the first T-shaped steel, and the other end is hinged to the longitudinal plate.

[0015] In this solution, the first cross plate and the second cross plate are used to provide an installation area for a large number of seismic components therebetween. The first cross plate and the second cross plate are respectively hinged to both ends of the longitudinal plate. In fact, under normal working conditions, the positions of the first cross plate and the second cross plate both remain unchanged relative to the steel-concrete column assembly. Therefore, the longitudinal plate should also remain stable under normal working conditions; when an earthquake occurs, the entire steel plate shear wall assembly undergoes displacement or deformation, which will cause the longitudinal plate to move. During this process, a large amount of seismic energy can be dissipated. In addition, when a lateral displacement occurs under the action of an earthquake, the steel-concrete column assembly can transfer the horizontal load to the seismic components through the first cross plate and the second cross plate, which can significantly improve the wall-column cooperative effect of this application and significantly improve the energy dissipation capacity.

[0016] Further, the seismic component includes a butterfly plate, the long axis of the butterfly plate extends longitudinally, and the width of the butterfly plate gradually decreases from both longitudinal ends to the middle.

[0017] During the research process, the inventor team of this case found that the steel plate shear walls used for earthquake resistance in the prior art are generally slotted steel plates. The theoretical value of the moment at the middle section of the vertical strip inside is zero, and there are also situations where the overall instability of the slotted steel plate is serious and local stress concentration leads to tearing of the steel plate. Therefore, the earthquake resistance of the slotted steel plate shear wall in the prior art is still insufficient. To overcome this problem, this solution uses a butterfly plate that is wider at both the upper and lower ends and narrower in the middle as an earthquake-resistant component. Through this design form, the distribution range of the yield area when the wall is stressed is increased, which can effectively avoid premature damage caused by stress concentration at the ends of the butterfly plate, thereby enhancing the anti-fatigue ability of the shear wall; and when subjected to horizontal reciprocating earthquake loads, the middle section of the butterfly plate is prone to out-of-plane torsion, and energy is dissipated through torsional deformation, which has better ductility and energy dissipation performance compared with traditional slotted steel plates.

[0018] Further, the butterfly plate includes several rows; the top end of the uppermost row of butterfly plates is detachably connected to the first cross plate; the bottom end of the lowermost row of butterfly plates is detachably connected to the second cross plate; adjacent two butterfly plates are detachably connected through a connecting plate.

[0019] This solution facilitates the independent replacement of one or more butterfly plates, thereby extending the service life and reducing the maintenance cost of prefabricated buildings. At the same time, this layout method can make each butterfly plate more flexible and independent in out-of-plane torsion, further ensuring the energy dissipation performance.

[0020] Further, at least one stiffening rib is connected between each row of butterfly plates.

[0021] For several rows of butterfly plates, there are several butterfly plates in each row. This solution uses stiffening ribs to connect the butterfly plates within the same row, which is used to limit the out-of-plane deformation of the middle area of the butterfly plate, and then convert the torsional deformation in the middle of the butterfly plate under horizontal reciprocating loads into bending deformation, significantly improving its energy dissipation ability.

[0022] Further, it also includes a fitting plate for clamping the middle area of the butterfly plate, a cover plate detachably connected to the fitting plate, and a positioning plate fixedly connected to the fitting plate;

[0023] At the relative two ends of one side surface of the fitting plate, clamping parts matching the middle area of the butterfly plate are provided, and the thickness of the clamping parts is greater than or equal to the thickness of the butterfly plate; the cover plate is connected to the clamping parts at both ends;

[0024] The positioning plate and the cover plate are respectively located on both sides of the fitting plate. Two chutes are provided on the positioning plate in a relatively distributed manner, and the stiffening rib is clamped between the two chutes.

[0025] In this solution, a stiffening rib is connected between each row of butterfly plates. The stiffening rib is located in the middle and narrower area of the butterfly plate. The fitting plate is attached to one side surface in the middle of the butterfly plate, and the two ends of the middle area of the butterfly plate are clamped by the clamping parts at both ends. Then, the upper cover plate is covered on the other surface of the butterfly plate, and the cover plate is connected to the two clamping parts, so as to realize the fixed connection between the fitting plate and the corresponding butterfly plate, and avoid relative displacement between the fitting plate and the corresponding butterfly plate in any direction. Since a positioning plate is fixed on each fitting plate, when all the butterfly plates in the same row are at the same height, the sliding grooves on all the positioning plates in the same row are opposite to each other, and the stiffening rib can be inserted into them uniformly, so that the upper and lower ends of the stiffening rib are respectively located in the two sliding grooves distributed up and down, realizing the temporary positioning and installation of the stiffening rib. The stiffening rib in this solution is not only convenient for installation, but also convenient for disassembly and replacement, which is beneficial to the later maintenance of this application. In addition, under the combined action of the fitting plate, the positioning plate and the stiffening rib, the out-of-plane torsion of the middle position of the butterfly plate can be more fully restricted, so that under the horizontal reciprocating load, the two ends of the butterfly plate undergo out-of-plane torsion and the middle area undergoes bending deformation, thereby significantly improving the lateral stiffness and energy dissipation capacity of the seismic component.

[0026] Furthermore, the stiffening rib is a second T-shaped steel, and the flange of the second T-shaped steel is clamped between the two sliding grooves. Inevitably, the web of the second T-shaped steel extends away from the butterfly plate. This structure can further improve the restriction effect of the stiffening rib on the out-of-plane torsion of the middle area of the butterfly plate, and further improve the lateral stiffness and energy dissipation capacity of the seismic component.

[0027] Furthermore, it also includes a transfer plate. The transfer plate is provided with a groove on the side surface for clamping the web of the first T-shaped steel. A number of longitudinally arranged grooves are also provided on the surface of the transfer plate; both the first cross plate and the second cross plate are connected to the transfer plate.

[0028] In the process of further research, the inventor team found that since the upper and lower ends of the steel plate shear wall component in this application need to be connected to the web of the first T-shaped steel by bolts, it will cause a large load on the steel plate shear wall component, especially the first cross plate and the seismic component will bear a large load, which is not conducive to the full play of the energy dissipation and seismic functions of the shear wall. Therefore, this solution also sets a transfer plate. The web of the first T-shaped steel is clamped by the groove on the transfer plate, and then the first cross plate and the second cross plate are respectively connected to the upper and lower ends of the transfer plate. In this connection method, the vertical force at the upper part of the steel plate shear wall component can be transferred to the bottom through the transfer plate, thereby reducing the load on the first cross plate and the seismic component and being conducive to the full play of their energy dissipation and seismic functions. In addition, a number of longitudinally arranged grooves are also provided on the surface of the transfer plate to avoid stress concentration and reduce the self-weight of the transfer plate at the same time.

[0029] Compared with the prior art, the present invention has at least the following advantages and beneficial effects:

[0030] 1. A prefabricated butterfly shear wall-column system of the present invention uses a specific steel-concrete column assembly as the column structure of a prefabricated building. High-ductility concrete is filled into the space surrounded by four bent plates and consolidated. Through the synergistic effect of the two materials, a significant improvement in the bearing capacity is achieved.

[0031] 2. A prefabricated butterfly shear wall-column system of the present invention realizes the connection between the steel plate shear wall assembly and the steel-concrete column assembly through the first T-shaped steel, which can further improve the bearing capacity of the column structure, enhance its flexural stiffness, and at the same time can also realize the mechanical transfer between the wall and the column, improving the integrity of the wall-column system.

[0032] 3. A prefabricated butterfly shear wall-column system of the present invention. The four bent plates can be used as templates, which is convenient for concrete pouring; the steel-concrete column assembly can be used as both a load-bearing column and a damping column, and its hysteretic performance is significantly improved compared with that of ordinary concrete-filled steel tubes.

[0033] 4. A prefabricated butterfly shear wall-column system of the present invention.

[0034] 5. A prefabricated butterfly shear wall-column system of the present invention. When a lateral displacement occurs under seismic action, the steel-concrete column assembly can transfer the horizontal load to the seismic component through the first transverse plate and the second transverse plate, which can significantly improve the wall-column synergy effect of this application and significantly improve the energy dissipation capacity.

[0035] 6. A prefabricated butterfly shear wall-column system of the present invention uses a special butterfly plate as a seismic component, which increases the distribution range of the yield area when the wall is stressed, can effectively avoid premature failure caused by stress concentration at the end of the butterfly plate, thereby enhancing the anti-fatigue ability of the shear wall; and when subjected to horizontal reciprocating seismic loads, the middle section of the butterfly plate is prone to out-of-plane torsion, and energy is dissipated through the torsional deformation, which has better ductility and energy dissipation performance compared with traditional slotted steel plates.

[0036] 7. A prefabricated butterfly shear wall-column system of the present invention. Under the combined action of the fitting plate, the positioning plate and the stiffening rib, the out-of-plane torsion of the middle position of the butterfly plate can be more fully restricted, so that under horizontal reciprocating loads, the two ends of the butterfly plate undergo out-of-plane torsion and the middle area undergoes bending deformation, thereby significantly improving the lateral stiffness and energy dissipation capacity of the seismic component.

[0037] 8. An assembled butterfly shear wall-column system of the present invention transfers the vertical force at the upper part of the steel plate shear wall component to the bottom through a transfer plate, thereby reducing the load-bearing of the first transverse plate and the seismic component and facilitating the full play of its energy dissipation and seismic functions.
