[0022] like Figure 2 As shown, the utility model discloses a concrete wall vibration isolation structure, which is arranged on a building raft 1; it includes a concrete column base 2 centrally arranged in the concrete wall. Specifically, the concrete column base 2 includes a groove-shaped gravel layer 21, and a cushion layer 22 and a raft layer 23 arranged in the gravel layer 21. Among them, the gravel layer 21 is filled with sand and gravel in a ratio of 1:1, and the thickness of the gravel layer 21 in the present application is preferably 1200±100mm, wherein the groove bottom thickness is preferably 500±100mm, and the side wall thickness is preferably 133±3mm. The thickness of the cushion layer 22 is preferably 100±50mm. The thickness of the raft layer 23 is preferably 600±100mm, and the top surface of the raft layer 23 is coplanar with the plane where the groove of the gravel layer 21 is located. The thickness of each layer in the concrete column base 2 can be adjusted according to the construction requirements, and only a preferred parameter range is provided here, and no specific limitation is made.

[0023] like Figure 1 to Figure 2 As shown, a group of concrete columns 3 are centrally distributed in a circular shape on the concrete column base layer 2. The concrete columns are distributed in a circular shape between the concrete column base layer and the equipment foundation layer, and provide support for the equipment foundation layer and the equipment thereon, so that the equipment foundation layer is subjected to force balance, and the force stability of the concrete wall is enhanced. At the same time, it is convenient for the equipment placed on the equipment foundation layer to quickly and effectively transmit the vibration force downward. Furthermore, the concrete columns 3 are arranged on the raft layer 23; the width of each of the concrete columns 3 is preferably 500±10mm. The structure of the concrete columns 3 is a known prior art and will not be elaborated here. In addition, the cross-sectional shape of the concrete columns 3 can be a known shape such as a rectangle or a circle, which can be adjusted according to the use requirements and is not limited here.

[0024] like Figure 2As shown, both sides of each concrete column 3 are filled with a vibration isolation layer 5; in the present application, the vibration isolation layer 5 is preferably made of foam material. The spacing between the concrete column 3 located at the periphery and the concrete column 3 at the center is 867±3mm, and the vibration isolation layer 5 is filled within this spacing range. The vibration isolation layer 5 with a thickness of 383±3mm is filled between the concrete column 3 located at the periphery and the inner wall of the concrete wall; the outer side of the vibration isolation layer 5 is coplanar with the outer side of the sand and gravel layer 21. It can be seen that in the present application, by filling the vibration isolation layer between the concrete columns and between the concrete columns and the concrete walls, the vibration force is directly transmitted to the concrete column base layer at the bottom of the concrete column during the operation of the vibration equipment, and the overall vibration of the building is effectively reduced through the vibration isolation layer, thereby improving the safety of the building structure.

[0025] Further, such as Figure 2 As shown, a concrete beam 4 is connected between two adjacent concrete columns 3; the two adjacent concrete columns are connected by the concrete beam, so that all the concrete columns form a whole, which effectively enhances the stability of the structure; at the same time, it is conducive to the transmission of force after the concrete column is stressed, and timely disperses the force acting on a certain concrete column or some concrete columns, thereby extending the service life of the concrete column. In addition, since a vibration isolation layer is also provided between the concrete columns, the vibration force will be absorbed by the concrete columns and the vibration isolation layer distributed around the concrete column after being transmitted to the concrete column, and the vibration force will be further transmitted downward, reducing the range of peripheral diffusion of the vibration force, thereby effectively preventing the vibration of the equipment from causing cracks in the bottom surface of the building and its surroundings, and reducing the impact on the stability of the surrounding equipment.

[0026] like Figure 2 As shown, the top of the concrete column 3 is provided with an equipment foundation layer 6, and the equipment foundation layer 6 is spaced apart from the inner wall of the concrete wall, and the gap between the two is preferably 50±10mm; that is, a gap of 50±10mm is formed between the equipment foundation layer 6 and the inner wall of the concrete wall. The structure of the equipment foundation layer 6 is consistent with the structure of the raft layer 23, and its thickness is 600±100mm; the upper surface of the equipment foundation layer 6 is flush with the ground. Since there is a certain gap between the equipment foundation layer 6 and the concrete wall, after the heavy vibration equipment arranged on the equipment foundation layer is started, the vibration force will be directly transmitted downward by the equipment foundation layer, effectively reducing the impact on the exterior wall of the building, thereby improving the overall safety of the building.

[0027] Furthermore, the cushion layer 22 is provided between the top of the vibration isolation layer 5 and the equipment foundation layer 6, and the thickness of the cushion layer 22 is 100±50 mm. In the process of transmitting the vibration force downward, the cushion layer can effectively reduce the vibration force of the concrete column and the gravel layer from the equipment foundation layer and the raft layer respectively, thereby protecting and extending the service life of the overall structure.

[0028] There are many implementation methods of the utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
