Description
Technical Field
[0001] This utility model belongs to the field of vibration reduction technology for container houses, specifically a self-vibration damping base frame for container houses. Background Technology
[0002] Container houses are a type of movable and reusable building product. They are modularly designed and factory-produced, using containers as the basic unit. They can be used individually or combined in different horizontal and vertical directions to create spacious living spaces.
[0003] The base frame of a container house is a crucial structural component, supporting the weight of the entire container and providing a stable foundation. As the connection between the ground and the container house, the base frame transmits seismic energy to the container house during an earthquake. To reduce the impact of earthquakes on the container house, existing base frames are equipped with shock-absorbing mechanisms, which rely on springs. However, existing base frames are difficult to prevent external debris from entering, allowing it to easily seep into the base frame through gaps. This debris hinders the expansion and contraction of the internal springs, affecting the self-damping effect of the base frame.
[0004] Therefore, this utility model provides a self-damping base frame for a container house. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figures 1 to 5 As shown, a self-damping base frame for a container house according to an embodiment of this utility model includes a support frame 1 and a top frame 12; multiple connecting rods 13 are fixedly connected to the bottom of the top frame 12; a first spring 14 is fixedly connected to the middle of the connecting rod 13; multiple sleeves 15 are fixedly connected to the top of the support frame 1; a connecting groove 16 is opened on the top of the support frame 1; a protective film 17 is fixedly connected to the bottom of the top frame 12; an adhesive strip 18 is fixedly connected to the bottom end of the protective film 17; during operation, the bottom ends of the multiple connecting rods 13 are respectively inserted into the interior of the multiple sleeves 15, and the bottom end of the first spring 14 will abut against the top of the sleeve 15. When vibration occurs, the connecting rods Relative sliding and friction will occur between 13 and sleeve 15, and sleeve 15 will be compressed, consuming or absorbing some of the energy generated by vibration, reducing the vibration of the container house above the top frame 12. After the connection between the support frame 1 and the top frame 12 is completed, the rubber strip 18 is inserted into the connection groove 16, so that the protective film 17 opens and blocks the gap between the support frame 1 and the top frame 12, making it difficult for foreign objects to enter through the gap between the support frame 1 and the top frame 12. Through the above structure, it is difficult for foreign objects to enter the bottom of the container house, reducing the impact of debris accumulation at the bottom of the container house on the self-damping effect of the base frame.
[0024] like Figures 1 to 3As shown, an elastic membrane sleeve 2 is fixedly connected to the middle of the connecting rod 13; a connecting ring 21 is fixedly connected to the bottom end of the elastic membrane sleeve 2; a second spring 22 is fixedly connected to the side wall of the connecting ring 21; a limiting plate 23 is fixedly connected to the other end of the second spring 22; the limiting plate 23 is slidably connected to the bottom of the connecting ring 21; during operation, after connecting the connecting rod 13 and the sleeve 15, the connecting ring 21 is fitted onto the top side wall of the sleeve 15 and the elastic membrane sleeve 2 is in an extended state, and the limiting plate 23 is used to hook the edge of the top of the sleeve 15, so that the elastic membrane sleeve 2 can protect the first spring 14 inside, making it difficult for foreign objects to contact the first spring 14. Through the above structure, the occurrence of foreign objects entering the middle of the first spring 14 and causing the first spring 14 to be difficult to extend and retract normally can be reduced, thereby reducing the impact on the energy absorption effect of the first spring 14 and reducing the impact on the self-damping effect of the base frame.
[0025] like Figures 1 to 5 As shown, the rubber strip 18 has multiple limiting holes 3 in the middle; the connecting groove 16 has multiple through holes 31 on its side wall; a pin 32 is detachably installed in the middle of the through hole 31; during operation, after the rubber strip 18 is inserted into the connecting groove 16, the multiple limiting holes 3 and the through holes 31 are in an overlapping state. At this time, the multiple pins 32 can be inserted into the multiple limiting holes 3 through the through holes 31, making it difficult for the rubber strip 18 to rise and detach from the connecting groove 16. Through the above structure, the occurrence of the rubber strip 18 detaching from the connecting groove 16 due to external force can be reduced, thereby reducing the occurrence of foreign objects easily entering the base frame after the rubber strip 18 detaches from the connecting groove 16.
[0026] like Figures 1 to 5 As shown, the top of the support frame 1 has multiple sets of insertion holes 4; a connecting frame 41 is detachably installed in the middle of the insertion hole 4; a baffle 42 is fixedly connected to the bottom of the connecting frame 41; during operation, after multiple pins 32 are inserted into the through hole 31, in order to prevent the pins 32 from falling out of the through hole 31, a screw is usually used instead of the pins 32 and inserted into the through hole 31 by thread. However, this connection method is time-consuming and laborious. As an alternative, the connecting frame 41 is inserted into the insertion hole 4. At this time, the baffle 42 will block and limit the side wall of the pins 32, making it difficult for the pins 32 to slide outward. This setting can reduce the occurrence of the pins 32 falling out and is more convenient than the threaded connection method. With the above structure, the pins 32 can be prevented from falling out of the through hole 31 without the aid of threads, so that the pins 32 can stably limit the rubber strip 18 and reduce the occurrence of the rubber strip 18 falling out of the connecting groove 16.
[0027] like Figures 1 to 2As shown, multiple first magnets 5 are fixed to the top of the support frame 1; multiple second magnets 51 are fixed to the bottom of the top frame 12; the first magnets 5 and the second magnets 51 are arranged to repel each other; through the above structure, the repulsive force between multiple sets of first magnets 5 and second magnets 51 can be used to absorb and disperse vibration energy, thereby improving the self-damping effect of the base frame.
[0028] like Figures 1 to 2 As shown, a vibration isolation pad 6 is fixed to the top of the top frame 12; the vibration isolation pad 6 is made of rubber; through the above structure, when the base frame vibrates, the transmission of vibration energy to the building above the vibration isolation pad 6 can be reduced, further improving the self-damping effect of the base frame.
[0029] like Figure 5 As shown, multiple drainage grooves 7 are provided at the bottom of the side wall of the connecting groove 16. With the above structure, rainwater can enter the interior of the connecting groove 16 through the gap between the connecting groove 16 and the rubber strip 18, and then be discharged through multiple drainage grooves 7, making it difficult for rainwater to accumulate inside the connecting groove 16 and reducing the corrosion caused by long-term accumulation of rainwater to the components.
[0030] During operation, the bottom ends of multiple connecting rods 13 are inserted into the interiors of multiple sleeves 15. The bottom end of the first spring 14 abuts against the top of the sleeve 15. When vibration occurs, relative sliding and friction occur between the connecting rods 13 and the sleeves 15, and the sleeves 15 are compressed, consuming or absorbing some of the energy generated by the vibration, thus reducing the vibration of the box-type house above the top frame 12. After completing the connection between the support frame 1 and the top frame 12, the adhesive strip 18 is inserted into the connecting groove 16, causing the protective membrane 17 to open and block the gap between the support frame 1 and the top frame 12, making it difficult for foreign objects to enter through the gap between the support frame 1 and the top frame 12. After connecting the connecting rods 13 and the sleeves 15, the connecting ring 21 is fitted onto the top side wall of the sleeve 15, and the elastic membrane sleeve 2 is in an extended state. The limiting plate 23 is used to hook the edge of the top of the sleeve 15, allowing the elastic membrane sleeve 2 to... The first spring 14 is protected inside, making it difficult for foreign objects to contact it. After the rubber strip 18 is inserted into the connecting groove 16, the multiple limiting holes 3 and the through holes 31 are in an overlapping state. At this time, multiple pins 32 can be inserted into the multiple limiting holes 3 through the through holes 31, making it difficult for the rubber strip 18 to rise and fall out of the connecting groove 16. After the multiple pins 32 are inserted into the through holes 31, in order to prevent the pins 32 from falling out of the through holes 31, a screw is usually used instead of the pins 32 and inserted into the through holes 31 by thread. However, this connection method is time-consuming and laborious. As an alternative, the connecting bracket 41 is inserted into the insertion hole 4. At this time, the baffle 42 will block and limit the side wall of the pin 32, making it difficult for the pin 32 to slide outward. This setting can reduce the occurrence of the pin 32 falling out and is more convenient than the threaded connection method.
