[0038] Embodiment 1

[0039] Reference Figure 1 As shown in the figure, a shock-absorbing, sound-insulating and heat-insulating prefabricated building structure is shown in the figure. 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 provided between the first support column 105 and the second support column in the vertical direction. One side of the beam-slab 113 is hinged to the first support column 105, and the other side of the beam-slab 113 is rigidly connected to the second support column. The prefabricated building structure of the present application realizes vibration isolation and energy dissipation of the structure in a rigid-flexible combination manner, and ensures the structural strength and stability of the building structure.

[0040] Preferably, the beam-slab 113 is fixed between the first support column 105 and the second support column. A bracket 109 is provided on the side of the first support column 105. A third isolation support 110 is fixedly arranged on the top side of the bracket 109. The edge part of the beam-slab 113 is fixedly connected to the top end of the third isolation support 110. The third isolation support 110 is a flexible support structure, thereby realizing the hinge connection between the beam-slab 113 and the first support column 105.

[0041] Preferably, a heat-insulating and sound-insulating filler 111 is filled in the gap between the beam-slab 113 and the first support column 105.

[0042] Traditional reinforced concrete buildings all improve the structural stiffness to resist seismic loads and horizontal shear forces. However, sound waves, like seismic waves, are all transmitted by vibration. Improving the stiffness further enhances the sound transmission performance of rigid components. This is why the sound insulation performance of many current building structures is poor. In addition, there are also noises caused by internal strains of the structure due to stresses brought about by external loads and temperatures on rigid structures.

[0043] In response to the above phenomena, the present application has solved them separately. First, for the most difficult problem of solid-borne sound, a sound bridge is set up to change the fixed connection into a flexible connection and become a sliding support. A hinge support is formed between components (the hinge connection between the beam-slab 113 and the first support column 105), and an expansion joint is provided (the gap between the beam-slab 113 and the first support column 105), so that the structure can deform relatively, reduce internal forces, and adapt to the permanent stress and instantaneous stress brought about by different seasonal climates and external dynamic loads.

[0044] Preferably, an ear plate 114 is provided on the side of the second support column. The beam-slab 113 is fixedly connected to the ear plate 114 through reinforced concrete, thereby realizing the rigid connection between the beam-slab 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 portion 101 , and the ear plate 114 is prefabricated on the side of the second support section 108 .

[0046] Preferably, when the beam 113 is fixed on the corbel 109, a notch 115 is provided between the beam 113 and the ear plate 114, and ribs extend from the beam 113 and the ear plate 114 on opposite sides respectively; a formwork support structure 116 is provided on the bottom side of the beam 113 to assist in arranging a casting mold in the notch 115, thereby completing the casting of concrete on the beam 113 and the ear plate 114, and realizing a rigid connection between the beam 113 and the second support column.

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

[0048] Preferably, the first isolation support 104, the second isolation support 107, and the third isolation support 110 are seismic isolation support bodies, which include: a first flange plate anti-leakage slurry pad 301, a seismic isolation support 302, and a second flange plate 306, wherein 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 plate 306 of the seismic isolation support 302, and a damping material 303 is filled on the side of the spring 304, and the second flange plate 306 is movably connected to the top of the seismic isolation support 302 through a hoop 305. Therefore, the upper part of the isolation support is filled with spring 304 and damping material 303, which has a great unloading effect on the horizontal shear force, and the lower part of the seismic isolation support 302 is a composite material support compression structure, generally a sound insulation and shock absorption high pressure resistant structure, such as a lead plate and a rubber plate. The present application solves the problem of vertical sound transmission and solid heat transfer through each isolation support, that is, cutting off the path and using an isolation support, which not only isolates sound and heat, but also improves the seismic and shock absorption performance of the structure.

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

[0051] The prefabricated building structure of this application adopts a combination of rigidity and flexibility to achieve structural vibration isolation and energy dissipation, and ensure the structural strength and stability of the building structure. The large frame is equipped with vertical shear members, rigid beams and slabs are arranged horizontally, and flexible isolation supports are arranged in local areas. The two sides of the beam and slab are rigid and flexible, and are consolidating on one side and hinged on the other. The beam and slab not only bear horizontal stress, but also resist the problem of excessive strain caused by different deformations.

[0052] The foregoing are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
