DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0021] Example: Refer to Figure 1-Figure 4 , a precast concrete component used for the ground foundation of a movable panel house, including a fixed load-bearing plate 1, and also including: a plurality of support components are arranged at the bottom of the fixed load-bearing plate 1, and the support components are hollow; a movable load-bearing plate 5, and the movable load-bearing plate 5 is arranged on the upper part of the fixed load-bearing plate 1; a lifting component; the lifting component passes through the fixed load-bearing plate 1 and the movable load-bearing plate 5; when the lifting component is driven to rotate, the support component opens to all sides, and the movable load-bearing plate 5 rises upward; the supporting component includes: a load-bearing column 11, a first movable petal 21, and a second movable petal 22, the load-bearing column 11 is fixedly connected to the bottom of the fixed load-bearing plate 1; the first movable petal 21 is rotatably connected to the lower part of the load-bearing column 11, and the second movable petal 22 is rotatably connected to the first movable petal 21; the lifting component includes: a lifting plate 23, a turntable 231, a threaded rod 3, and a top plate 4, and the lifting plate 23 is rotatably connected to the bottom of the second movable petal 22 The turntable 231 is fixedly connected to the lifting plate 23, one end of the threaded rod 3 is inserted into the turntable 231, and the turntable 231 is also rotatably connected to the limiting plate 31, the limiting plate 31 is fixedly connected to one end of the threaded rod 3, the threaded rod 3 penetrates the fixed load-bearing plate 1 and is threadedly connected to the fixed load-bearing plate 1, and the other end of the threaded rod 3 is fixedly connected to the top plate 4; a groove is provided on the movable load-bearing plate 5, and the groove corresponds to the top plate 4. When the movable load-bearing plate 5 contacts the fixed load-bearing plate 1, the top plate 4 is slidably connected in the groove; a hexagonal nut 41 is fixedly connected to the top plate 4, and the hexagonal nut 41 penetrates the movable load-bearing plate 5 and is rotatably connected to the movable load-bearing plate 5; a limiting block 221 is fixedly connected to the second movable petal 22, and when the second movable petal 22 is perpendicular to the lifting plate 23, the limiting block 221 resists the lifting plate 23; the surfaces of the supporting assembly and the fixed load-bearing plate 1 are coated with an anti-corrosion coating;

[0022] When in use, the construction workers first dig a pit for placing the prefabricated components at the construction site, place the prefabricated components horizontally in the pit, and then fill the pit with soil until the load-bearing column 11 is completely buried. At this time, a suitable hexagonal wrench is inserted into the hexagonal nut 41, and the wrench is turned to rotate the threaded rod 3. Since the threaded rod 3 and the fixed load-bearing plate 1 are threadedly connected, the threaded rod 3 will move upward, driving the lifting plate 23 to move upward. The movement of the lifting plate 23 will open the first movable petal 21 and the second movable petal 22 outward. , so that the angle between the first movable flap 21 and the second movable flap 22 becomes smaller, and the first movable flap 21 and the second movable flap 22 are penetrated into the soil to improve the fixing effect. At the same time, the rise of the threaded rod 3 will push the top plate 4 upward, prompting the movable load-bearing plate 5 to move upward together. When the threaded rod 3 can no longer be rotated, a cavity will be formed between the fixed load-bearing plate 1 and the movable load-bearing plate 5. Soil can be filled in the cavity to further enhance the fixing effect, or foam board material can be filled in the cavity to provide shock-absorbing and shock-absorbing effects for the movable load-bearing plate 5.

The lifting component drives the supporting component to be expanded outward and penetrated into the soil, thereby improving the fixing effect in the soil. At the same time, the movable load-bearing plate 5 can be lifted to form a cavity between the fixed load-bearing plate 1 and the movable load-bearing plate 5. The cavity can be further filled with soil to improve the fixing effect, and the cavity can also be filled with shock-absorbing materials to improve the living comfort of the formed movable house. After the movable house is dismantled, the prefabricated structure can be disassembled and reused, thereby improving the economy and reducing the generation of construction waste.
