[0004] Insufficient earthquake resistance: Some older buildings are not designed according to modern earthquake-resistant standards and are easily damaged during earthquakes. Limited application of seismic damping technology: Although seismic damping technologies (such as seismic isolation bearings and dampers) exist, their adoption rate is low due to high costs.

[0005] 2. Sound insulation

[0006] Poor sound insulation: Insufficient sound insulation performance of walls, floors, etc., leads to significant noise transmission. Inappropriate material selection: Inconsistent quality of sound insulation materials affects the overall sound insulation effect.

[0007] 3. Insulation

[0008] Poor thermal insulation performance: Some building insulation materials have poor performance, resulting in high energy consumption. Substandard construction quality: Improper construction methods and gaps in the insulation layer affect the insulation effect.

[0009] 4. Comprehensive Issues

[0010] Lagging technological updates: The adoption of new technologies is slow, and many buildings still use traditional materials and methods. Inadequate maintenance: Lack of regular maintenance leads to a decline in vibration damping, sound insulation, and thermal insulation performance over time. Summary of the Invention

[0038] Example 1

[0039] refer to Figure 1 As shown in the figure, a vibration-damping, sound-insulating, and heat-insulating prefabricated building structure is illustrated. The prefabricated building structure includes a first support column 105 and a second support column. The first support column 105 is a rigid column, and the second support column is a flexible column. A beam-slab 113 is vertically positioned between the first support column 105 and the second support column. One side of the beam-slab 113 is hinged to the first support column 105, and the other side is rigidly connected to the second support column. This application's prefabricated building structure employs a combination of rigidity and flexibility to achieve vibration isolation and energy dissipation, while ensuring the structural strength and stability of the building structure.

[0040] Preferably, the beam plate 113 is fixed between the first support column 105 and the second support column; the first support column 105 is provided with a corbel 109 on its side, and a third isolation support 110 is fixedly provided on the top side of the corbel 109; the edge of the beam plate 113 is fixedly connected to the top of the third isolation support 110; the third isolation support 110 is a flexible support structure, thereby realizing the hinge connection between the beam plate 113 and the first support column 105.

[0041] Preferably, the gap between the beam 113 and the first support column 105 is filled with thermal insulation and sound insulation filler 111.

[0042] Traditional reinforced concrete buildings rely on increasing structural stiffness to resist seismic loads and horizontal shear forces. However, sound waves, like seismic waves, propagate through booleans. Increasing stiffness further enhances the sound transmission performance of rigid components, which is why many building structures have poor sound insulation. Additionally, the stress caused by external loads and temperature on rigid structures leads to internal structural strain, which in turn generates noise.

[0043] To address the above issues, this application provides a phased solution. First, for the most challenging issue of solid-borne sound transmission, a sound bridge is constructed, transforming the fixed connection into a flexible one, essentially a sliding support. Hinged supports are formed between the components (the hinged relationship between the beam / slab 113 and the first support column 105), and expansion joints (the gap between the beam / slab 113 and the first support column 105) are provided, allowing the structure to deform relatively, reducing internal forces, and adapting to permanent and instantaneous stresses caused by different seasonal climates and external dynamic loads.

[0044] Preferably, the second support column is provided with an ear plate 114 on its side, and the beam plate 113 is connected and fixed to the ear plate 114 by reinforced concrete, thereby realizing a rigid connection between the beam plate 113 and the second support column.

[0045] Furthermore, a second isolation support is provided between the first support section 106 and the second support section 108 in the second support column; the first support section 106 is fixed on the base support part 101, and the ear plate 114 is prefabricated on the side of the second support section 108.

[0046] Preferably, when the beam plate 113 is fixed on the corbel 109, there is a notch 115 between the beam plate 113 and the ear plate 114, and the beam plate 113 and the ear plate 114 have reinforcing bars extending from their respective sides; by setting a template support structure 116 on the bottom side of the beam plate 113 to assist in arranging the casting mold at the notch 115, concrete is poured on the beam plate 113 and the ear plate 114, thereby achieving a rigid connection between the beam plate 113 and the second support column.

[0047] Preferably, the bottom end of the first support column 105 is provided with a first isolation support 104.

[0048] Preferably, the first isolation support 104, the second isolation support 107, and the third isolation support 110 are seismic isolation seats, each seismic isolation seat comprising: a first flange plate 301, a seismic isolation support 302, and a second flange plate 306. The first flange plate 301 is fixedly connected to the bottom side of the seismic isolation support 302, and the second flange plate 306 is connected to the top side of the seismic isolation support 302.

[0049] Furthermore, a spring 304 is provided between the second flange plates 306 of the seismic isolation bearing 302, and damping material 303 is filled on the side of the spring 304. The second flange plate 306 is movably connected to the top of the seismic isolation bearing 302 via a sleeve 305. Thus, the upper part of the isolation bearing is filled with spring 304 and damping material 303, which has a large unloading effect on horizontal shear force. The lower part of the seismic isolation bearing 302 is a composite material bearing compression structure, generally a sound insulation, vibration reduction and high pressure resistance structure, such as a combination of lead plate and rubber plate. This application solves the problem of vertical sound transmission and solid heat transfer by using isolation bearings, which both isolate sound and heat and improve the seismic resistance and vibration reduction performance of the structure.

[0050] Preferably, a floating ceiling 118 is provided on the bottom side of the beam 113, and the floating ceiling 118 is connected to the beam 113 via a damping rod 117.

[0051] This application employs a combination of rigid and flexible methods to achieve vibration isolation and energy dissipation in the prefabricated building structure, while ensuring the structural strength and stability of the building. The main frame is equipped with vertical shear-resistant members, while rigid beams and slabs are arranged laterally. Flexible isolation supports are installed in localized areas. The beams and slabs are rigid on one side and flexible on the other, with one side fixed and the other hinged. This allows the beams and slabs to not only withstand horizontal stress but also resist excessive strain caused by different deformations.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
