Embodiment 1

[0030] see Figure 1-Figure 2 , a composite damping frame unit, including a rectangular supporting frame body 1, in this embodiment, the supporting frame body 1 is a steel frame structure formed by welding rectangular steel materials.

[0031] see figure 1 , image 3 with Figure 4 , the inside of the top corner of the support frame body 1 is provided with a vibration-damping corner piece 2 . Specifically, vibration-damping corner pieces 2 are respectively arranged inside the eight corners of the supporting frame body 1 . The vibration-damping corner piece 2 has a black hole region, and the distance between the inner and outer surfaces of the black-hole region of the vibration-damping corner piece 2 increases exponentially from the central axis to the outer edge. The outer surface of the vibration damping corner piece 2 is a concave spherical surface, and the inner surface of the black hole area of ​​the vibration damping corner piece 2 is a concave black hole concave sur...

Embodiment 2

[0039] A composite vibration-damping frame system, the composite vibration-damping frame system is composed of several composite vibration-damping frame units described in Embodiment 1, and the supporting frame body of the composite vibration-damping frame unit is welded. The damping plates of the composite damping frame unit form a periodic cell unit structure in six directions of the supporting frame body, and can form a periodic space damping structure with other units to absorb external vibration energy.

Abstract

The invention discloses a composite type vibration-damping frame unit and a vibration-damping frame system, which belong to the technical field of civil engineering. The composite type vibration-damping frame unit includes a rectangular support frame body, which is characterized in that: the inner side of the top corner of the support frame body A vibration-damping corner piece with an acoustic black hole structure is provided, a vibrating plate with an acoustic black hole structure is provided on the inner side of the end face of the support frame body, and a vibration-damping film is provided on the end face of the support frame body, corresponding to the same end face of the support frame body A vibration-damping column with an acoustic black hole structure is arranged between the vibration-damping plate and the vibration-damping film. The composite damping frame unit has the characteristics of high strength, high rigidity, high vibration resistance, and high noise reduction. Under the combined action of multiple composite damping frame units, a new acoustic black hole and thin-film oscillator structure can be formed, thereby further improving the building frame. The efficiency of vibration and noise reduction of the structure.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a composite vibration-damping frame unit and a vibration-damping frame system. Background technique [0002] At present, the mainstream form of building structure is to adopt the frame structure, that is, the building skeleton of the frame structure is first established, and then other building constructions are carried out. As the skeleton of the building, the frame structure needs to support the weight of the entire building, and at the same time it is also subject to the combined effects of external complex excitations, such as frequent human-induced excitations, earthquake excitations, noise excitations, etc. Therefore, the frame structure will Fatigue, deformation, cracks and other phenomena appear under the action. On this basis, people improve the frame structure of the building. In order to improve the rigidity index of the frame structure, steel fr...
