Description

Technical Field

[0001] The utility model relates to the technical field of building engineering vibration suppression, in particular to an active and passive intelligent control system for building earthquake resistance. Background Art

[0002] Building earthquake resistance means that earthquake-resistant design must be carried out in areas with an earthquake fortification intensity of 6 degrees or above. Earthquake damage to major projects and lifeline projects is highly harmful and causes serious losses. Therefore, compared with general building structures, it is required to increase the corresponding earthquake fortification requirements for major projects and lifeline projects. Construction projects must be earthquake-resistant in accordance with earthquake fortification requirements and earthquake-resistant design specifications, and constructed in accordance with earthquake-resistant designs. Earthquake-resistant design is carried out according to fortification requirements and specifications, and construction must be carried out according to design. Earthquake-resistant design and construction are important measures to reduce earthquake disasters. The earthquake-resistant design of high-rise buildings should follow the basic principles of coordinating the rigidity and flexibility of the building structure, paying attention to the rules of the building structure, and paying attention to multiple defenses.

[0003] The purpose of earthquake-resistant design of high-rise buildings is to formulate a series of feasible earthquake-resistant measures to improve the earthquake resistance of high-rise buildings. At present, there are many earthquake-resistant measures for buildings, such as reinforcement of the main building, isolation of the foundation and the main building, etc. In the earthquake-resistant design of high-rise buildings, it is necessary to comprehensively consider the key points and precautions of high-rise building construction, and select scientific and reasonable earthquake-resistant measures, which can not only meet the relevant standards for building earthquake resistance, but also reduce the use of unnecessary earthquake-resistant measures as much as possible, saving raw materials while improving the earthquake resistance of high-rise buildings.

[0004] Most of the existing seismic resistance technologies use passive seismic resistance, which has low flexibility and has problems such as poor structural stability, high energy consumption, poor flexibility and adaptability. It cannot make adjustment measures according to the actual situation of the earthquake, which reduces the seismic performance. Therefore, in order to achieve the combination of active and passive seismic resistance in high-rise buildings, it is necessary to design an active and passive intelligent control system for building seismic resistance.

Example

[0031] The active and passive intelligent control system for building earthquake resistance includes a translation component control unit and a rotation component control unit; the translation component control unit is fixed on the foundation support through a pre-buried screw rod in the foundation, and the rotation component control unit is connected to the translation component control unit.

[0032] The translational component control unit includes a passive chamber base steel plate 11 fixed to a foundation support by embedded screws, a passive chamber 13 welded to the passive chamber base steel plate 11, and a passive chamber sealing steel plate fixed to the passive chamber 13 (a circular hole is provided in the middle of the passive chamber sealing steel plate 12 for connecting components in the passive chamber 13 with an active chamber bottom plate 21 under the active chamber 22). The passive chamber base steel plate 11 and the passive chamber sealing steel plate 12 are ribbed at four corners of the passive chamber 13. The passive chamber base steel plate 11 and the passive chamber sealing steel plate 12 are connected to a connecting steel plate 31 via a central steel column 16 in the passive chamber 13. The lower end of the central steel column 16 in the passive chamber 13 is mounted on the passive chamber base steel plate 11 via a movable bearing, and the upper end is fixed to the connecting steel plate 31.

[0033] The passive chamber 13 is filled with displaceable steel plates, a portion of which is fixed to the central steel column, and a steel plate adjacent to the portion of the steel plate is fixed to the inner wall of the passive chamber, and a viscous liquid is filled between two adjacent steel plates.

[0034] The rotational component control unit includes a passive control assembly and an active control assembly. The passive control assembly is the part connecting the passive chamber and the active chamber, and the active control assembly is connected to the passive control assembly.

[0035] The passive control assembly consists of a connecting steel plate 31 and an active chamber bottom plate 21, and a horizontally movable relative displacement steel column 33 connecting the two parts. This part is directly connected to the central steel column 16 in the passive chamber 13, and moves horizontally with the central steel column 16 and the steel plate in the passive chamber; the active control assembly includes an active controller, a motor base, a drive motor 23 fixed on the motor base, a rotating shaft connected to the drive motor 23, and a rotating mass disk 24 connected to the top of the rotating shaft.

[0036] The offset steel plates in the passive room can be displaced to offset the energy of the earthquake. The passive room outer wall is also required to limit the displacement to prevent long-distance displacement in one direction and regulate the movement range of the central steel column in the passive room.

[0037] The connection between the passive chamber and the active chamber is connected by two steel plates and a central steel column at a possible earthquake location. When the earthquake is too large or the tilt is severe, this connection can be disconnected to reduce the impact of uneven force in the passive chamber on the active chamber.

[0038] The active chamber has a motor that rotates to correct the building's tilt, and the passive chamber reduces the disturbance of the building's horizontal displacement;

[0039] The active control assembly is installed in the cylindrical shell, the motor base is fixed to the bottom of the cylindrical shell, and the cylindrical shell is capped with a steel plate.

[0040] A bearing is installed between the central steel column 16 in the active chamber and the annular bottom plate, and the central steel column 16 is connected to the rotating mass disk through a fixing sleeve.

[0041] The active controller includes a sensor and a controller. The sensor monitors the dynamic parameters of the building and the working status of the active control assembly, and feeds back signals to the controller, which controls the operation of the drive motor. Example

[0042] The active and passive intelligent control system for building earthquake resistance includes a translation component control unit and a rotation component control unit; the translation component control unit is fixed on the foundation support through pre-buried screws, and the rotation component control unit is connected to the translation component control unit.

[0043] The translational component control unit includes a screw rod pre-buried in the foundation and a reserved screw hole, which connects the passive chamber base steel plate 11 to the foundation. The offset steel plate I in the passive chamber is fixedly connected to the outer wall of the passive chamber 13, and the offset steel plate II 15 not connected to the outer wall is connected to the central steel column 16. The purpose of the offset connection of these two steel plates is to add a viscous liquid such as a damping liquid into the passive chamber 13 to increase the relative sliding force between the two steel plates and improve performance.

[0044] The central steel column 16 is connected to the connecting steel plate 31. A circular steel plate is provided at the opening of the passive chamber sealing steel plate 12 to seal the opening, but the opening will not affect the translation of the central steel column 16. The size of the opening is the size range that limits the displacement of the central steel column 16.

[0045] The passive chamber 13 and the active chamber 22 are connected by two steel plates and a connecting support 32, wherein a total of four corner columns are connected to the central steel column 16 in the middle to ensure the stability of the active chamber.

[0046] The rotation component control unit includes a passive control assembly and an active control assembly. The passive control assembly is connected to the active bottom plate 21 , and the active control assembly is connected to the passive control assembly.

[0047] The active chamber 22 contains an active controller, a motor base, a drive motor 23 fixed on the motor base, a rotating shaft connected to the drive motor, and a rotating mass disk 24 connected to the top of the rotating shaft. The sensor is used to receive and sense signals, the drive motor 23 is located in an annular sleeve 25, the active controller is also located in the annular sleeve 25, and the active chamber top plate 26 is connected to the structural column of the upper building, which is also rigidly connected through pre-buried screws.

[0048] When an earthquake occurs, if the magnitude of the earthquake is small and the amplitude of the shaking is small, the passive chamber 13 plays a major role at this time, isolating the upper buildings from the ground, and the building structure itself will not tilt. As the impact of the earthquake continues to increase, the amplitude of the shaking of the building becomes larger and larger, and relying solely on passive control for earthquake protection no longer meets the requirements. At this time, active control and passive control coordinate with each other. Active control transmits instructions by detecting the tilt and shaking amplitude of the building, and controls the angular velocity, mass and angular distance of the mass disk through the motor, thereby inhibiting the tilt and deviation of the building. The viscous liquid in the passive control also weakens the slippage of the central steel column 16, thereby enhancing the inhibition effect.

[0049] The building's seismic active and passive intelligent control system adopts a composite design of translational shock absorption and rotational shock isolation, which can not only prevent the translational displacement caused by earthquakes, but also promptly correct the building's tilt, reduce the building's vibration amplitude, and maintain the safety of the building structure. The impact of the surrounding environment's vibration on the overall building is negligible; active and passive synergy plays a role in saving energy.
