Description

Technical Field

[0001] The invention relates to the technical field of building shock absorption, and in particular to a wall structure and a building. Background Art

[0002] In modern building construction, in order to increase the earthquake resistance of the wall, the wall is usually divided into several wall units, and the vibration reduction devices between the wall units are used to restrain each other, thereby reducing damage to the wall. At present, building dampers are a control device for vibration reduction, which are widely used in high-rise buildings, bridges, towers and other projects. They mainly consume external forces such as earthquake energy and wind energy to reduce the vibration amplitude of the building under severe vibration or wind, thereby ensuring the structural safety and comfort of the building.

[0003] Among them, the principle of building dampers is to utilize the characteristics of damper materials to convert energy into heat energy or other forms of energy during vibration and release it, thereby reducing the amplitude of the structure. Common building dampers include pendulum dampers, liquid dampers and friction dampers, etc., which can not only reduce the vibration amplitude of the building and avoid structural damage, but also provide a more comfortable use environment. At the same time, the use of building dampers can also reduce the building's requirements for the foundation and reduce construction costs.

[0004] The installation of the existing building damper of the wall structure is to connect the earrings at both ends of the piston rod to the two wall units through the supports respectively, and the piston rod can reciprocate in the cylinder. This installation structure requires a large installation space and is not suitable when the space is narrow. In addition, since the cylinder is movable, it is easy to rotate in the space, and the stability is poor, which reduces the service life of the building damper and further affects the vibration reduction and earthquake resistance performance of the wall structure.

[0050] Building shock absorption is to install energy-absorbing devices at certain parts of the structure (such as supports, shear walls, joints or connectors4), which generate friction, bending (or shear, torsion), elastic-plastic (or viscoelastic) hysteresis deformation to dissipate or absorb the energy input into the structure by earthquake, so as to reduce the seismic response of the main structure, thereby avoiding damage or collapse of the structure and achieving the purpose of shock absorption control.

[0051] The various frictions and other obstacles that attenuate free vibrations are called damping. A damper is a device that provides resistance to movement and consumes the energy of movement. The damper is placed on the structural system to provide resistance to movement and consume the energy of movement.

[0052] At present, the damper is installed on the wall structure by connecting the earrings at both ends of the piston rod 61 to the two wall units through the support, and the piston rod 61 can make reciprocating motion in the cylinder. This installation structure requires a large installation space and is not suitable when the space is narrow. In addition, since the cylinder is movable, it is easy to rotate in the space, and the stability is poor, which reduces the service life of the building damper, thereby affecting the vibration reduction and earthquake resistance performance of the wall structure.

[0053] In order to solve the above problems, the present application proposes a wall structure and a building having the wall structure, so as to effectively solve the problem that the existing wall structure with a damper requires a large installation space.

[0054] like Figure 1-Figure 4 As shown, the wall structure of the present application includes a wall unit, a connector 4 and a damper. The wall unit includes a main body 11 and a protrusion 12 protruding from the main body 11. There are two wall units, the two wall units are arranged at intervals in the vertical direction, and the protrusions 12 of the two wall units are arranged opposite to each other in the horizontal direction. There are two connectors 4, which are respectively arranged inside the two protrusions 12. The two ends of the damper are respectively hinged to the two connectors 4, and the axis of the damper can rotate in at least two planes.

[0055] The wall structure described in the present application is provided with a wall unit having a protrusion 12, and a connector 4 is provided on the protrusion 12. At the same time, two wall units are arranged at intervals in the vertical direction, and the protrusions 12 of the two wall units are arranged oppositely in the horizontal direction, and a damper is respectively hinged to the two connectors 4. Such a configuration can effectively reduce the number of steel bars inside the wall unit and ensure the structural strength of the wall structure, thereby helping to reduce the space occupied by the wall, and further helping to solve the problem that the existing wall structure requires a large installation space. By providing the connector 4 inside the protrusion 12, and hingedly providing the connector 4 with the damper, and limiting the axis of the damper to rotate in at least two planes, on the one hand, it helps to improve the connection strength between the damper and the wall unit, and further improve the seismic structural strength of the wall; on the other hand, it helps to enhance the lateral stiffness of the wall structure and ensure the buffering effect of the damper, so as to avoid losing the protective effect on the building due to damage to the internal structure before absorbing and consuming energy.

[0056] Specifically, the structures of the two wall units of the wall structure of the present application are the same. For the convenience of description, the two wall units are respectively referred to as the first wall unit 1 and the second wall unit 2, and the following description takes the first wall unit 1 as an example. Figure 1 As shown, the first wall unit 1 includes a main body 11 and a protrusion 12 protruding from the main body 11, wherein the main body 11 is a rectangular parallelepiped structure as a whole, and the protrusion 12 is arranged on one end face of the main body 11 in the vertical direction, and the protrusion 12 is located at one end of the main body 11 in the horizontal direction, that is, the first wall unit 1 is an "L"-shaped structure as a whole. In this embodiment, both wall units are cast in reinforced concrete, and the above-mentioned connector 4 and damper are used to form a structural member that bears the vertical load and horizontal load caused by wind load or earthquake, that is, a shear wall.

[0057] It is important to understand that the wall unit is cast with steel bars and concrete. Steel bars, as a material with high strength and toughness, can withstand great tensile forces. While concrete has high compressive strength, its tensile strength is relatively low. Therefore, in building structures, steel bars are mainly used to withstand and resist tensile forces, while concrete is used to withstand and resist compressive forces. In this way, steel bars and concrete can complement each other and work together to improve the stability of the overall structure.

[0058] It should be further understood that the main body 11 has a hidden column 3 arranged in the vertical direction, and one end of the hidden column 3 extends into the raised portion 12. In this embodiment, hidden columns 3 and hidden beams are arranged inside the main body 11. Along the length direction, there are two hidden columns 3 and they are respectively arranged at both ends of the main body 11. The two ends of the hidden beam are respectively fixedly connected to the two hidden columns 3, wherein the hidden beam is not shown in the figure. By arranging hidden columns 3 and hidden beams inside the main body 11, it helps to ensure the structural strength of the main body 11. Since the first wall unit 1 in the present application has a raised portion 12 protruding from the main body 11, in order to ensure the connection strength between the raised portion 12 and the main body 11, as shown in FIG. Figure 2 As shown, one end of the hidden column 3 is extended into the raised portion 12, thereby strengthening the structural strength between the raised portion 12 and the main body 11. As a preferred implementation method, the hidden column 3 is formed by overlapping ribs and beams. Specifically, the hidden column 3 includes a plurality of vertical ribs arranged in the vertical direction. In the width direction, the vertical ribs are arranged at the two side ends of the main body 11, and each side end is provided with a plurality of vertical ribs. A plurality of connecting beams are arranged between two adjacent vertical ribs. Such an arrangement is convenient for improving the structural strength and construction efficiency of the wall unit, and makes the force of the entire wall structure more clear.

[0059] like Figure 2 As shown, in the vertical direction, the first wall unit 1 and the second wall unit 2 are arranged at intervals, and the sides of the two wall units provided with the raised portions 12 are arranged close to each other. At this time, in the horizontal direction, the two raised portions 12 are arranged opposite to each other. In this embodiment, connectors 4 are arranged inside the two raised portions 12. Among them, the connectors 4 are connected to the wall units by pre-embedding or welding to form a rigid load-bearing component with a clear force transmission path, and are arranged on the wall units as the base of anti-seismic components such as dampers. In this embodiment, the connector 4 is buried inside the raised portion 12. Specifically, the connector 4 is arranged in the horizontal direction, and one end of the connector 4 is hinged to the damper, and at this time, in the width direction, the connector 4 is arranged between the two vertical ribs.

[0060] At this time, the two ends of the damper are respectively hinged to the two connecting members 4, and the axis of the damper can rotate in at least two planes. Specifically, the damper is arranged horizontally, and the two ends of the damper are respectively hinged to the two connecting members 4, and at the same time, the damper can rotate in at least two planes. It can be understood that a hinge structure is arranged between the damper and the connecting member 4, and the hinge structure enables the damper to rotate in at least two planes. The hinge structure can be set as a matching structure of multiple bearings and earrings, wherein a rotating shaft is arranged on the bearing, and the two ends of the rotating shaft are fixed by the mounting structure on the damper, and at this time, the earrings are arranged on the connecting member 4. Of course, in addition to this, the hinge structure can also be set to other forms, such as a hinge seat and a sphere forming a ball joint structure, etc., which can also realize the rotation of the damper in at least two planes.

[0061] When a natural disaster (earthquake or strong wind) occurs, the wall structure will tend to rotate outside the plane of the building. The present application limits the damper to be hinged with the connector 4, and the axis of the damper can rotate in at least two planes, so that when a natural disaster occurs, the wall structure can be rotated outside the plane of the building, which helps to avoid the misalignment of the axis of the damper caused by the rigid connection of the damper, thereby ensuring the buffering effect of the entire damper and avoiding the loss of the protective effect on the building due to damage to the internal structure before it absorbs and consumes energy.

[0062] It should be understood that the damper is an energy dissipation component, and is connected to the connector 4 by welding, flange connection, or hinge, etc., to form an axial force-bearing mechanism, so that the damping force reacts on the overall mechanism to offset or dissipate part of the seismic force, thereby improving the lateral stiffness of the wall. In this embodiment, the damper is configured as a viscous damper. Among them, the viscous damping wall is made based on the principle of fluid movement, especially when the fluid passes through the throttling hole, it will generate throttling resistance. It is a damper related to the speed of piston movement. When installed, it is directly stuck in the gap of the wall structure (that is, the gap between the two wall units), so as to achieve the effect of slowing down and reducing the vibration of the building.

[0063] The present application sets a wall unit with a protrusion 12, and sets two wall units at intervals in the vertical direction, and the protrusions 12 of the two wall units are set opposite to each other. At the same time, a connector 4 is set inside the protrusion 12 in the horizontal direction, and a viscous damper is set between two adjacent connectors 4. Such a setting helps to change the force form of the wall from bending shear force to tensile pressure force. At the same time, the wall structure of the present application optimizes the gap h2 between the wall units from the original 400mm to the current 300mm, wherein the spacing between the protrusion and the wall opposite to it is Δh≤50mm, and at this time Δh=h 2 -h1 The wall structure of the present application also has the shortest length L of the wall. 1 Optimizing from 1500mm to 1200mm helps to improve the applicability of walls with dampers in building functions and solve the problem that existing wall structures require a larger installation space. It can also arrange the position of dampers more conveniently and quickly, reduce the difficulty of embedded parts construction, and thus improve work efficiency.

[0064] It should be understood that the length, width and height of the raised portion 12 are related to the output range of the damper. Among them, the damping force and total displacement of the viscous damper are positively correlated with its external dimensions, that is, when the damping force is constant, the greater the total displacement, the larger the external dimensions; when the total displacement is constant, the greater the damping force, the larger the external dimensions. In practical applications, the model selection (selection of external dimensions) of the viscous damper needs to be selected in combination with the actual needs (length) of the wall, and at this time, due to the different damping forces, the raised portion 12 is subjected to different shear forces in the axial direction. In order to ensure that the raised portion 12 is not damaged by the shear force, it is necessary to have sufficient cross-sectional dimensions. At present, the output of conventional building dampers is in the range of 100KN to 1000KN. Due to the structural strength requirements of the wall, the length L of the raised portion 12 2 should be greater than 300 mm, the width of the raised portion 12 should be greater than 200 mm, and the height h of the raised portion 12 should be greater than 200 mm. 1 In this embodiment, the raised portion 12 is set to 300*200*250 (mm 3 ), and at this time, the length, width and height of the protrusion 12 are the minimum dimensions.

[0065] It should be further understood that in order to ensure that the protrusion 12 is not damaged by shear force, the protrusion 12 needs to have a sufficient cross-sectional size, but its length L 2 It can be further shortened as needed. Figure 3As shown, a prefabricated member 9 is arranged inside the wall unit. Specifically, in the horizontal direction, a prefabricated member 9 is arranged at one end with a protruding portion 12, and the prefabricated member 9 is buried inside the main body 11. In the vertical direction, one end of the prefabricated member 9 abuts against the bottom surface of the main body 11, and the other end of the prefabricated member 9 extends to the top surface of the protruding portion 12. In the horizontal direction, the part of the prefabricated member 9 located at the protruding portion 12 is fixedly connected to one end of the connecting member 4. The arrangement of the prefabricated member 9 can further strengthen the connection strength between the protruding portion 12 and the main body 11. At the same time, the fixed connection between the connecting member 4 and the prefabricated member 9 is conducive to the conduction of the force in the wall and ensures the connection effect between the wall unit and the damper. At this time, the length of the protruding portion 12 can be further shortened as needed, that is, the shortest length of the wall can be further optimized, which helps to further improve the applicability of the wall structure of the present application. In this embodiment, the prefabricated member 9 is set as a steel section. Of course, the preform 9 may also be configured as other structures or devices so as to ensure the connection strength between the protrusion 12 and the main body 11 while satisfying the requirement of reducing the length of the protrusion 12 .

[0066] At this time, the above-mentioned connecting member 4 includes an embedded plate 41 and a cross bar 42, wherein the number of the embedded plates 41 is set to at least two, and they are arranged at intervals in the horizontal direction, and the cross bar 42 is fixedly connected to at least two embedded plates 41. At this time, at least one of the two embedded plates 41 is used to be hinged with the damper, and the other embedded plates 41 are cast inside the raised portion 12 to ensure the installation and fixation of the connecting member 4 on the raised portion 12. In this embodiment, the cross bar 42 is made of steel bars or steel bars welded. By setting at least two embedded plates 41 arranged in the horizontal direction and cooperating with the connection of the cross bar 42, it is helpful to improve the fixing effect of the connecting member 4 and the raised portion 12, and to improve the structural strength of the wall unit. At the same time, the cross bar 42 cooperates with the embedded plate 41, which can effectively transmit the tensile pressure of the wall structure during natural disasters.

[0067] It should be noted that most of the existing embedded parts are connected by steel bars, and due to the limitation of the installation method, they are subject to bending and shearing forces. However, the biggest advantage of steel bars is high tensile strength and low shearing strength. Therefore, the present application changes the force direction of the embedded parts by providing a protrusion 12 and arranging the connecting part 4 in the horizontal direction, that is, the steel bars are arranged horizontally, and fixedly connected with at least two embedded plates 41. In actual use, the tensile and compressive axial forces of the damper will be directly transmitted to the embedded parts, and the characteristics of the embedded parts (steel bars) will be fully utilized. Such a setting helps to reduce the amount of steel bars used, thereby helping to solve the problem of installation difficulties caused by excessive reinforcement of the embedded parts.

[0068] Specifically, if Figure 2As shown, the number of embedded plates 41 is set to two, and along the horizontal direction, the two embedded plates 41 are respectively arranged at the two ends of the protruding portion 12, at this time, the cross bar 42 passes through the protruding portion 12, and the two ends of the cross bar 42 are respectively fixedly connected to the two embedded plates 41. In this embodiment, the outer side surface of the embedded plate 41 and the end surface of the protruding portion 12 are located on the same vertical plane, and the cross bar 42 and the embedded plate 41 are fixed by welding. The two embedded plates 41 are arranged at the two ends of the protruding portion 12 and connected by the cross bar 42 passing through the protruding portion 12, which helps to further improve the fixing effect of the connecting member 4 on the protruding portion 12 and maximize the force transmission effect.

[0069] In this embodiment, the cross bar 42 is arranged in a columnar shape, and the axis of the cross bar 42 is located on the same straight line as the axis of the damper. By limiting the axis of the cross bar 42 and the axis of the damper to be located on the same straight line, the axis of the connecting member 4 and the axis of the damper are located on the same straight line. In this way, the axis rotation of the damper is integrated at the hinge between the damper and the connecting member 4, thereby avoiding the axis misalignment problem of the damper due to its own rigid connection, helping to ensure the buffering effect of the entire damper, and avoiding the loss of the protective effect on the building due to the damage of the internal structure before absorbing and consuming energy.

[0070] In addition, if Figure 4 As shown, the number of cross bars 42 can be set to multiple, and in this case, multiple cross bars 42 are arranged around the axis of the damper. In this embodiment, the embedded plate 41 is set to a disc-shaped structure, and multiple cross bars 42 are arranged around the axis of the embedded plate 41 and at intervals. When the embedded plate 41 is hinged to the damper, the axis of the connecting member 4 and the axis of the damper are located on the same straight line. By limiting the installation position of multiple cross bars 42, the present application can ensure that the axis of the connecting member 4 and the axis of the damper are located on the same straight line, thereby helping to ensure the uniform distribution of tensile pressure, and further helping to further improve the lateral strength of the wall structure.

[0071] At this time, the damper includes a cylinder body 5, a piston device 6 and a fixing member 7. Among them, a first mounting portion 81 is provided at one end of the cylinder body 5, the piston device 6 has a piston rod 61 movably plugged into the cylinder body 5, and a second mounting portion 82 is provided at one end of the piston rod 61 located outside the cylinder body 5. There are two fixing members 7, and the first mounting portion 81 and the second mounting portion 82 are both connected to the buried plate 41 through the fixing member 7. The first mounting portion 81 and the second mounting portion 81 are hinged to the buried plate 41 through the fixing member 7, and in this case, the hinge of the first mounting portion 81 and / or the second mounting portion 82 can realize the rotation of the axis of the damper in at least two planes.

[0072] Specifically, the cylinder body 5 includes a cylindrical body 51, an end cover 52, a connecting tube 53 and a screw connection 54. Figure 2 As shown, both ends of the cylindrical body 51 are provided with end caps 52 to form a cavity with the cylindrical body 51, and a damping medium is provided inside the cavity. At the same time, the connecting cylinder 53 and the screw connector 54 are respectively screwed on the two ends of the cylindrical body 51, which, on the one hand, improves the installation effect of the end cap 52 and ensures the sealing effect of the cavity, and on the other hand, forms a motion cavity between the connecting cylinder 53 and the end cap 52. At this time, the piston device 6 includes a piston rod 61 and a piston body 62. Among them, the piston rod 61 is movably provided on the two end caps 52 to realize the movable insertion of the piston rod 61 on the cylinder body 5. The piston body 62 is arranged on the piston rod 61 and is located inside the cavity, and one end of the piston rod 61 is located outside the cylinder body 5, and the other end of the piston rod 61 is arranged in the motion cavity. Preferably, the piston rod 61 and the piston body 62 are integrally formed.

[0073] In this embodiment, one of the two embedded plates 41 used for connecting with the damper is set as a flange structure, and at the same time, a corresponding flange structure is set on the fixing member 7, so as to realize the bolt connection between the fixing member 7 and the embedded plate 41. Since the existing dampers are mostly welded to the embedded parts through the node plate, but the quality of the weld directly affects the effect of the damper, the present application is connected by bolts, which helps to improve the connection effect between the fixing member 7 and the embedded plate 41 and ensure the connection quality between the damper and the connecting member 4.

[0074] At this time, if Figure 4 As shown, the first mounting portion 81 and the second mounting portion 82 are both configured as a spherical structure, and the center of the spherical structure is located on the axis of the cylinder body 5. At the same time, a first accommodating portion 71 is provided on the embedded plate 41, and a second accommodating portion 411 is provided on the fixing member 7. The first accommodating portion 71 cooperates with the second accommodating portion 411 to form an accommodating space for accommodating the spherical structure, which can not only realize the clamping and fixing of the spherical structure, but also form a ball joint connection mode, thereby helping to improve the connection effect between the damper and the connecting member 4, and helping to further ensure the connection effect between the two wall units. At the same time, through the simple cooperation between the embedded plate 41 and the fixing member 7, the clamping and fixing of the spherical structure is realized, and a certain rotation angle is ensured between the damper and the wall unit. The structure is simple and easy to install. At the same time, the flange bolt connection mode helps to ensure the connection effect of the wall structure.

[0075] It should be further understood that the first mounting portion 81 and the second mounting portion 82 adopt the above-mentioned ball joint connection method, which can make the axis of the damper rotate freely within the range of ±6°. At present, the connection and fixation of existing dampers mostly adopt pins, node plates and other components to cooperate with embedded parts, but there is a connection gap when using this connection method, which makes a gap between the damper and the wall. For earthquake resistance, the existence of the gap will seriously affect the effectiveness of the damper, and thus cause immeasurable damage to the structure. By adopting the above-mentioned ball joint connection method, the present application can not only meet the impact of vibrations in multiple directions on structural components, but also help solve the problem of gaps between existing dampers and walls due to the use of pins, node plates and other components.

[0076] Here, it should be noted that, in addition to setting both the first mounting portion 81 and the second mounting portion 82 as a spherical structure, one of the first mounting portion 81 and the second mounting portion 82 can also be selectively set as a spherical structure, and the other can be set as a bearing connection structure. And in this case, the axis of the damper can still be rotatable in at least two planes, but in actual use, the effect of setting both the first mounting portion 81 and the second mounting portion 82 as a spherical structure is the best. In addition, in addition to the ball joint connection method, the present application can also adopt a ball crown connection method and a hemispherical joint connection method, both of which can achieve the rotation requirements of the damper in the present application, so no further details will be given here.

[0077] It should be further understood that the first mounting portion 81 and the cylinder body 5 are integrally formed, and / or the second mounting portion 82 and the piston rod 61 are detachably connected. In this embodiment, the first mounting portion 81 and the cylinder body 5 are integrally formed, and the second mounting portion 82 and the piston rod 61 are detachably connected. Specifically, the first mounting portion 81 and the connecting tube 53 are integrally formed. Figure 4 As shown, a mounting hole 821 is provided on the second mounting portion 82, and a screw connection column 611 is provided on the piston rod 61. Through the screw connection between the screw connection column 611 and the mounting hole 821, the second mounting portion 82 and the piston rod 61 can be detachably connected. Of course, in addition to this, the first mounting portion 81 and the cylinder body 5 can also be detachably connected, or the second mounting portion 82 and the piston rod 61 are integrally formed.

[0078] This embodiment also relates to a building, which includes the wall structure as described above.

[0079] Compared with the prior art, the building body proposed in the present invention has the technical advantages possessed by the above-mentioned wall structure, which will not be described in detail here.

[0080] 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 changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
