Example Embodiment

[0028] Example one

[0029] See Figure 1 to Figure 4 As shown, an anti-seismic structure for a shear beam includes a beam body 1, an anti-seismic frequency modulation mechanism 2 is provided on the upper surface of the beam body, which is used to change the natural frequency of the beam body to avoid resonance with seismic waves Frequency range to improve the seismic performance of the beam; the seismic frequency modulation mechanism includes a housing 3, the housing is provided with a balance chamber 4 and two damping chambers 5, the balance chamber is used to When the frequency is adjusted, excess damping liquid is stored. Each damping chamber is filled with damping liquid 6. The damping chamber is used to adjust the overall damping of the beam. Each damping chamber uses a common power The pump 7 is in communication with the balance chamber, and the power pump is in communication with each of the damping chambers through a battery valve 16; the seismic frequency modulation me...

Abstract

The invention relates to the technical field of shear beam anti-seismic structures, in particular to an anti-seismic structure for a shear beam and the shear beam. The anti-seismic structure for the shear beam comprises a beam body, and an anti-seismic frequency modulation mechanism is arranged on the upper surface of the beam body; the anti-seismic frequency modulation mechanism comprises a shellwhich is internally provided with a balance chamber and at least one damping chamber, and all the damping chambers are communicated with the balance chamber through power pumps; the anti-seismic frequency modulation mechanism further comprises a central controller and a vibration frequency sensor; the vibration frequency sensor and the central controller are fixed to a shell, all the power pumpsand the vibration frequency sensor are electrically connected with the central controller. According to the anti-seismic structure for the shear beam and the shear beam, by arranging the anti-seismicfrequency modulation mechanism, the vibration frequency of the beam body can be adaptively adjusted, the resonance risk is lowered, and the anti-seismic property of the beam body is effectively improved.

Description

technical field [0001] The invention relates to the technical field of anti-seismic structures of shear beams, in particular to an anti-seismic structure for shear beams and the shear beams. Background technique [0002] A house is a living space for humans, and design is the primary focus of the construction process. Architectural and structural designers have the responsibility to design and build more earthquake-resistant and earthquake-resistant structures, infiltrate new ideas for research on earthquake-resistant and disaster-prevention work, and reflect the concept of earthquake-resistance and disaster prevention in the whole process of residential design, from planning, design to construction. Thought. And existing house, anti-seismic grade is not high, in case the big earthquake of high level takes place, cause heavy loss to people's lives and property, seriously even cause the retrogression of national economic level. The aseismic design of shear beams is the most...
