Description

Technical Field

[0001] The present invention relates to the field of building construction, and in particular to an assembled butterfly 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 earthquake resistance of high-rise buildings.

[0003] In the existing technology, the walls and columns of prefabricated buildings are mostly designed separately. The seismic performance of traditional steel column structures is weak. At the same time, there are problems such as insufficient bearing capacity and low bending resistance. It is difficult to play a synergistic role with steel plate shear walls. Therefore, it is necessary to improve and optimize them. Summary of the Invention

[0004] The present invention provides an assembled butterfly shear wall-column system to solve the problems in the prior art of the weak integrity of the wall-column system of assembled buildings, resulting in insufficient synergy and weak seismic performance, thereby achieving the purpose of enhancing the integrity of the wall-column system and improving the bearing capacity, bending resistance and seismic resistance.

[0005] The present invention is achieved through the following technical solutions:

[0006] A prefabricated butterfly shear wall-column system includes a steel plate shear wall assembly and a steel-concrete column assembly. The steel-concrete column assembly includes four bent plates arranged in a square shape, and the interior of the four bent plates is filled with high-ductility concrete. A first T-shaped steel is sandwiched between two adjacent bent plates, and the wing plates of the first T-shaped steel are fixed to the interior of the high-ductility concrete, and the web plates of the first T-shaped steel extend to the exterior of the high-ductility concrete. The steel plate shear wall assembly is detachably connected to the web plates of the first T-shaped steel.

[0007] In response to the problem in the prior art that the wall-column system of prefabricated buildings has weak integrity, resulting in insufficient synergy and weak seismic performance, the present invention proposes an assembled butterfly shear wall-column system. This system is composed of four bent plates to form a square structure, and high-ductility concrete is filled in the square structure to obtain a steel-concrete composite column structure; since a first T-shaped steel is sandwiched between any two adjacent bent plates, the steel-concrete column assembly of the present application has a total of four first T-shaped steels, and the four webs corresponding to the four first T-shaped steels extend outward in four directions respectively, so that the steel-concrete column assembly of the present application can be connected to the steel plate shear wall assembly in any one or more of the four directions as needed. The present application can flexibly set the number of first T-shaped steels according to the requirements of the specific usage scenario to control the number of corresponding shear walls, thereby improving the flexibility and versatility of the prefabricated building.

[0008] The present application adopts a specific steel-concrete column assembly as the column structure of the prefabricated building, and fills high-ductility concrete into the space surrounded by four bent plates for consolidation. Through the synergistic effect of the two materials, a significant improvement in the bearing capacity is achieved. In addition, the four bent plates can be used as templates to facilitate the pouring of concrete. The present application uses a first T-shaped steel to achieve the connection between the steel plate shear wall assembly and the steel-concrete column assembly, which can further improve the bearing capacity of the column structure and enhance its bending stiffness. At the same time, it can also achieve mechanical transmission between the wall columns and improve the integrity of the wall column system. In addition, the steel-concrete column assembly of the present application can be used as both a load-bearing column and a damping column, and its hysteresis performance is significantly improved compared to ordinary steel tube concrete columns.

[0009] In addition, the term "high-ductility concrete" used in this application is a technical term, namely, ECC (Engineered Cementitious Composite) concrete. This application does not seek to improve the formula or components of high-ductility concrete. Those skilled in the art can use existing mature formulas or components. This application creatively uses high-ductility concrete in the column structure of prefabricated buildings. When the column structure is subjected to earthquakes, the bridging effect of the fibers within the concrete generates excellent ductility. Therefore, this application can significantly improve the seismic performance of the column structure in prefabricated buildings.

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

[0011] In this solution, the second and third bends serve as the outer walls of the column structure, while the first and fourth bends are used to sandwich and connect the corresponding webs of the first T-shaped steel, thereby achieving a connection between the first T-shaped steel and the bent plate. The first and fourth bends also provide positioning for the flanges, facilitating the quick and accurate installation of the first T-shaped steel before pouring concrete. After pouring concrete, the first and fourth bends, as well as the flanges and part of the web of the first T-shaped steel, are all fixed within the concrete. The bent plate structure further enhances the load-bearing capacity and flexural rigidity of the column structure.

[0012] Furthermore, the four bending plates are fixed and covered at the top and bottom ends by a sleeve assembly; the sleeve assembly includes four bending bars; the bending bars include a fifth bending portion, a sixth bending portion, a seventh bending portion and an eighth bending portion arranged vertically in sequence, the fifth bending portion and the seventh bending portion are respectively located on both sides of the sixth bending portion, the sixth bending portion and the eighth bending portion are respectively located on both sides of the seventh bending portion, the sixth bending portion is attached to the outer wall of the second bending portion, and the seventh bending portion is attached to the outer wall of the third bending portion; the fifth bending portion and the eighth bending portion are respectively attached to the webs of two adjacent first T-shaped steels and are bolted together.

[0013] This solution uses a collar assembly to wrap around the four bent plates at both the top and bottom ends to improve the integrity of the column structure, ensure stability during concrete pouring, and prevent the column structure from experiencing an elephant foot phenomenon when subjected to axial pressure. It should be noted that the structure of the collar assembly in this solution not only adapts to the outer wall shape of the bent plates, but also matches the web of the first T-section steel. Thus, a collar assembly is connected between the webs of two adjacent first T-section steels via bolts, thereby achieving relative fixation between the collar assembly and the bent plates.

[0014] Furthermore, the steel plate shear wall assembly includes a first horizontal plate and a second horizontal plate distributed upper and lower, a longitudinal plate hinged to the first horizontal plate and the second horizontal plate at both ends, and a number of seismic components connected between the first horizontal plate and the second horizontal plate; the first horizontal plate and the second horizontal plate are fixedly connected to the web of the first T-shaped steel at one end and hinged to the longitudinal plate at the other end.

[0015] In this solution, the first transverse plate and the second transverse plate are used to provide an installation area for a large number of earthquake-resistant components therebetween. The first transverse plate and the second transverse plate are hinged to the two ends of the longitudinal plate, respectively. In fact, under normal working conditions, the positions of the first transverse plate and the second transverse plate 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 is displaced or deformed, which causes the longitudinal plate to move. This process can greatly dissipate earthquake energy. In addition, when a lateral displacement occurs due to an earthquake, the steel-concrete column assembly can transfer the horizontal load to the earthquake-resistant 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.

[0016] Furthermore, the anti-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 the 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, and the theoretical value of the bending moment at the middle section of the vertical strips therein is zero. In addition, the slotted steel plates also have the problem of serious overall instability and local stress concentration leading to tearing of the steel plates. Therefore, the seismic resistance of the slotted steel plate shear walls in the prior art is still insufficient. In order to overcome this problem, this solution adopts butterfly plates that are wider at the upper and lower ends and narrower in the middle as seismic components. This design form increases the distribution of the yield range when the wall is subjected to stress, and can effectively avoid premature damage to the ends of the butterfly plates due to stress concentration, thereby enhancing the fatigue resistance of the shear wall. Moreover, when subjected to horizontal reciprocating loads from an earthquake, the middle section of the butterfly plate is prone to out-of-plane torsion, and energy is dissipated through torsional deformation. Compared with traditional slotted steel plates, it has better ductility and energy dissipation performance.

[0018] Furthermore, the butterfly plates include several rows; the top of the uppermost row of butterfly plates is detachably connected to the first transverse plate; the bottom of the lowermost row of butterfly plates is detachably connected to the second transverse plate; and adjacent butterfly plates are detachably connected via 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 costs of prefabricated buildings. Furthermore, this arrangement allows each butterfly plate to twist out of the plane more flexibly and independently, further ensuring energy efficiency.

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

[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 in the same row to limit the out-of-plane deformation of the middle area of ​​the butterfly plates, thereby converting the torsional deformation of the middle area of ​​the butterfly plates under horizontal reciprocating loads into bending deformation, thereby significantly improving its energy dissipation capacity.

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

[0023] Clamping parts matching the middle area of ​​the butterfly plate are provided at opposite ends of one side surface of the laminating plate, 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 bonding plate. Two relatively distributed sliding grooves are arranged on the positioning plate, and the stiffening rib is sandwiched between the two sliding grooves.

[0025] In this solution, a stiffening rib is connected between each row of butterfly plates. The stiffening rib is located in the narrow area in the middle of the butterfly plate, so that the bonding plate is attached to one side surface of 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, a cover plate is covered from the other surface of the butterfly plate, and the cover plate is connected to the two clamping parts, thereby achieving a fixed connection between the bonding plate and the corresponding butterfly plate, and preventing the bonding plate and the corresponding butterfly plate from relative displacement in any direction. Since a positioning plate is fixed to each bonding plate, when all butterfly plates in the same row are of the same height, the slide grooves on all positioning plates in the same row are opposite, and the stiffening ribs can be uniformly inserted therein, so that the upper and lower ends of the stiffening ribs are respectively located in the two slide grooves distributed above and below, thereby achieving temporary positioning and installation of the stiffening ribs. The stiffening ribs in this solution are not only easy to install, but also easy to disassemble and replace, which is beneficial to the later maintenance of this application; in addition, under the joint action of the bonding plate, positioning plate and stiffening ribs, the out-of-plane torsion in the middle 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, while the middle area undergoes bending deformation, thereby significantly improving the lateral stiffness and energy absorption capacity of the seismic resistant component.

[0026] Furthermore, the stiffening rib is a second T-shaped steel, with its flange sandwiched between the two chutes. Consequently, the web of the second T-shaped steel extends away from the butterfly plate. This structure further enhances the stiffening rib's ability to limit out-of-plane torsion in the butterfly plate's central region, further improving the lateral stiffness and energy dissipation capacity of the seismic-resistant component.

[0027] Furthermore, it also includes a transfer plate, which has a groove on the side, and the groove is used to clamp the web of the first T-shaped steel. The surface of the transfer plate also has several longitudinally arranged grooves; the first horizontal plate and the second horizontal plate are both connected to the transfer plate.

[0028] During a more in-depth study, the inventor team discovered that since the upper and lower ends of the steel plate shear wall assembly in this application need to be connected to the web of the first T-shaped steel by bolts, the load-bearing capacity of the steel plate shear wall assembly will be relatively large, especially the load-bearing capacity of the first transverse plate and the seismic component will be relatively large, which is not conducive to the shear wall fully exerting its energy dissipation and seismic resistance functions; for this reason, this solution also provides a transfer plate, which clamps the web of the first T-shaped steel through the groove on the transfer plate, and then connects the first transverse plate and the second transverse plate to the upper and lower ends of the transfer plate respectively. This connection method can transfer the vertical force of the upper part of the steel plate shear wall assembly to the bottom through the transfer plate, thereby reducing the load-bearing capacity of the first transverse plate and the seismic component, which is conducive to fully exerting its energy dissipation and seismic resistance functions. In addition, a number of longitudinally arranged grooves are provided on the surface of the transfer plate to avoid stress concentration while reducing the weight of the transfer plate.

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

[0030] 1. The present invention provides an assembled butterfly shear wall-column system, which uses a specific steel-concrete column assembly as the column structure of the assembled building.

[0031] 2. The present invention provides an assembled butterfly shear wall-column system, which realizes the connection between the steel plate shear wall assembly and the steel-concrete column assembly through the first T-steel, which can further improve the bearing capacity of the column structure and enhance its bending stiffness. At the same time, it can also realize the mechanical transmission between the wall columns and improve the integrity of the wall-column system.

[0032] 3. The present invention provides an assembled butterfly shear wall-column system, in which four bent plates can be used as formwork to facilitate the pouring of concrete; the steel-concrete column assembly can be used as both a load-bearing column and a damping column, and its hysteresis performance is significantly improved compared to ordinary steel tube concrete columns.

[0034] 5. The present invention provides an assembled butterfly shear wall-column system. When a lateral displacement occurs due to an earthquake, 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 the present application and significantly improve the energy consumption capacity.

[0035] 6. The present invention provides an assembled butterfly shear wall-column system, which adopts a special butterfly plate as an anti-seismic component, increases the distribution of the yield range when the wall is subjected to stress, and can effectively avoid premature damage due to stress concentration at the end of the butterfly plate, thereby enhancing the fatigue resistance of the shear wall; and when subjected to horizontal reciprocating loads of an earthquake, the middle section of the butterfly plate is prone to out-of-plane torsion, and energy is consumed through torsional deformation, which has better ductility and energy dissipation performance than traditional slotted steel plates.

[0036] 7. The present invention provides an assembled butterfly shear wall-column system, which, under the joint action of the bonding plate, the positioning plate and the stiffening ribs, can more fully limit the out-of-plane torsion in the middle of the butterfly plate, so that under horizontal reciprocating loads, the two ends of the butterfly plate undergo out-of-plane torsion, while the middle area undergoes bending deformation, thereby significantly improving the lateral stiffness and energy absorption capacity of the seismic component.

[0037] 8. The present invention provides an assembled butterfly shear wall-column system, which transmits the vertical force of the upper part of the steel plate shear wall assembly to the bottom through the transfer plate, thereby reducing the load-bearing capacity of the first horizontal plate and the seismic component, which is conducive to fully exerting its energy consumption and seismic resistance functions.
