Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a modular building foundation buffer connection base for earthquake resistance. Background Technology

[0002] With the rapid development of construction technology, modular housing has been widely used in residential, commercial, and temporary building sectors due to its advantages such as short construction cycle, controllable cost, and minimal environmental impact. However, earthquakes, as a sudden and destructive natural disaster, pose a serious threat to the safety of modular housing. Traditional earthquake-resistant technologies often focus on enhancing the overall stiffness of the building structure or using a single buffer material to resist earthquake energy. However, in the field of modular housing, these technologies often struggle to balance earthquake resistance performance with the flexibility of modular design.

[0003] Currently, although some earthquake-resistant foundation buffer devices exist on the market, most of them have the following shortcomings: 1. Insufficient seismic performance: Modular houses lack an effective buffering mechanism between the base and the foundation or supporting structure. The horizontal and vertical vibration energy generated by seismic waves is directly transmitted to the main body of the building, which can easily lead to failure of the connection nodes between modules, wall cracking, or even overall collapse.

[0004] 2. Low energy dissipation efficiency: In the existing technology, although some bases use a single rubber pad or spring for shock absorption, they do not form a multi-level energy dissipation system, which is difficult to cope with the multi-directional impact of complex seismic waves, and the materials are prone to aging and failure after long-term use.

[0005] 3. Poor modular adaptability: Traditional bases are mostly monolithic designs, which are difficult to adapt to different terrains or the splicing needs of modular houses, resulting in low installation accuracy and high maintenance costs. Utility Model Content

[0006] To address the aforementioned issues, this utility model proposes a modular earthquake-resistant building foundation buffer connection base. By integrating high-density rubber pads, polymer memory foam boards, and multi-level earthquake-resistant mechanisms, a rigid-flexible coupled composite buffer system is constructed to achieve graded absorption and dissipation of earthquake energy. At the same time, the modular splicing design improves installation convenience and structural adaptability.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a modular earthquake-resistant building foundation buffer connection base, including a base and a support base. A high-density rubber pad is installed on the bottom surface of the base. Two second splicing grooves are opened inside the base. A polymer memory foam board is installed on the upper surface of the support base. Two first splicing grooves and two mounting grooves are opened inside the support base. An earthquake-resistant mechanism is provided between the two mounting grooves and the two second splicing grooves. The earthquake-resistant mechanism includes two limiting grooves opened inside the mounting grooves. A slider is slidably connected to the inner wall of each of the two limiting grooves. A support rod is installed between the two sliders. Two second springs are installed on the right side of the support rod, and two first springs are installed on the bottom surface of the support rod.

[0008] Preferably, in the above-mentioned modular housing earthquake-resistant building foundation buffer connection base, the right ends of the two second springs are both installed on the inner wall of the mounting groove, and the interior of the two second springs is fitted with a second damping rod.

[0009] Preferably, in the above-mentioned modular housing earthquake-resistant building foundation buffer connection base, the left ends of the two second damping rods are both installed on the right side of the support rod, and the right ends of the two second damping rods are both installed on the inner wall of the mounting groove.

[0010] Preferably, in the above-mentioned modular housing earthquake-resistant building foundation buffer connection base, the bottom end of the support rod is equipped with a splicing block, the splicing block is slidably connected to the inner wall of the second splicing groove, and two first springs are installed on the bottom surface of the splicing block.

[0011] Preferably, in the above-mentioned modular housing earthquake-resistant building foundation buffer connection base, the bottom ends of the two first springs are equipped with base plates, the base plates are slidably connected to the inner wall of the second splicing groove, and the interior of the two first springs is fitted with a first damping rod.

[0012] Preferably, in the above-mentioned modular housing earthquake-resistant building foundation buffer connection base, the top ends of the two first damping rods are installed on the bottom surface of the splicing block, and the bottom ends of the two first damping rods are installed on the upper surface of the base plate.

[0013] The advantages and beneficial effects of this utility model are: This invention effectively solves the problem of the lack of an effective buffer mechanism between the base and the foundation or supporting structure of modular houses by setting a high-density rubber pad on the bottom surface of the base, setting a polymer memory foam board on the upper surface of the support base, and designing an anti-seismic mechanism containing multiple springs and damping rods. This significantly improves the seismic performance. When an earthquake occurs, the high-density rubber pad can initially absorb the vertical vibration energy, the polymer memory foam board can further filter the high-frequency vibration energy, and the springs and damping rods in the anti-seismic mechanism work together to achieve multi-level buffering and dissipation of horizontal and vertical vibration energy. This prevents the vibration energy generated by seismic waves from being directly transmitted to the main body of the building, reduces the risk of failure of the connection nodes between modules, wall cracking, or even overall collapse, and effectively ensures the safety of modular houses in the event of an earthquake.

[0014] This utility model adopts a modular splicing design, which can adapt well to different terrains and the splicing needs of modular houses, improving the ease of installation and structural adaptability. The base and support are respectively provided with splicing grooves, and the anti-seismic mechanism cooperates with the installation slide, so that the components can be easily assembled and spliced ​​without complicated tools and cumbersome procedures, which greatly improves the installation efficiency, and also facilitates the later maintenance and replacement of components, reducing maintenance costs.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] like Figures 1 to 4 As shown, a modular housing earthquake-resistant building foundation buffer connection base includes a base 1 and a support base 3. A high-density rubber pad 2 is installed on the bottom surface of the base 1. Two second splicing grooves 6 are opened inside the base 1. A polymer memory foam board 4 is installed on the upper surface of the support base 3. Two first splicing grooves 5 and two mounting grooves 8 are opened inside the support base 3. An earthquake-resistant mechanism 7 is provided between the two mounting grooves 8 and the two second splicing grooves 6.

[0019] The base 1 is the fundamental support component connecting the entire base, used for connection to the foundation. A high-density rubber pad 2 is installed on its bottom surface. This rubber pad 2 is made of highly elastic rubber material, possessing excellent elasticity and damping properties, effectively absorbing vertical vibration energy and initially buffering seismic impact. Two second splicing grooves 6 are formed inside the base 1 for splicing and connection with the support base 3. The support base 3 is positioned above the base 1 to support the main body of the modular house and is connected to the base 1 via an anti-seismic mechanism 7. A polymer memory foam board 4 is installed on the upper surface of the support base 3. This board 4 has memory deformation characteristics, absorbing energy through its own deformation under pressure, especially providing excellent filtering effect for high-frequency vibrations. Two first splicing grooves 5 and two mounting grooves 8 are formed inside the support base 3. The first splicing grooves 5 are used for splicing with other modular components, and the mounting grooves 8 are used for installing the anti-seismic mechanism 7.

[0020] The seismic-resistant mechanism 7 includes two limiting grooves 701 formed inside the mounting groove 8. Sliding blocks 702 are slidably connected to the inner walls of both limiting grooves 701. A support rod 703 is installed between the two sliding blocks 702. Two second springs 708 are installed on the right side of the support rod 703, and two first springs 705 are installed on the bottom surface of the support rod 703. The right ends of the two second springs 708 are installed on the inner wall of the mounting groove 8. A second damping rod 709 is sleeved inside each of the two second springs 708. The left ends of the two second damping rods 709 are installed on the right side of the support rod 703. The right end of 09 is installed on the inner wall of the mounting groove 8. The bottom end of the support rod 703 is equipped with a splicing block 704. The splicing block 704 is slidably connected to the inner wall of the second splicing groove 6. Two first springs 705 are installed on the bottom surface of the splicing block 704. The bottom end of the two first springs 705 is equipped with a base plate 707. The base plate 707 is slidably connected to the inner wall of the second splicing groove 6. The inside of the two first springs 705 is fitted with a first damping rod 706. The top end of the two first damping rods 706 is installed on the bottom surface of the splicing block 704. The bottom end of the two first damping rods 706 is installed on the upper surface of the base plate 707.

[0021] Two seismic-resistant mechanisms 7 are provided, located symmetrically between the mounting groove 8 and the second splicing groove 6. Each seismic-resistant mechanism 7 includes two limiting grooves 701 formed inside the mounting groove 8. A slider 702 is slidably connected to the inner wall of the limiting groove 701, and a support rod 703 is installed between the two sliders 702. Two second springs 708 and two second damping rods 709 are installed on the right side of the support rod 703. The second springs 708 and the second damping rods 709 are used for seismic buffering in the lateral direction. A splicing block 704 is installed at the bottom of the support rod 703. Two first springs 705 and two first damping rods 706 are installed on the bottom surface of the splicing block 704. The first springs 705 and the first damping rods 706 are used for seismic buffering in the vertical direction. The base plate 707 is slidably connected to the inner wall of the second splicing groove 6, providing support for the first springs 705 and the first damping rods 706.

[0022] Working Principle: The modular earthquake-resistant building foundation buffer connection base provided by this utility model is based on a rigid-flexible coupling composite buffer system design. Through the synergistic effect of various components, it achieves graded absorption and dissipation of seismic energy. The specific working process is as follows: When an earthquake occurs, the vibrational energy generated by the seismic waves is first transmitted to the base 1 through the foundation. The high-density rubber pad 2 installed on the bottom surface of the base 1 plays its role first. It has good elasticity and damping characteristics and can absorb part of the vertical vibrational energy, thus initially buffering the earthquake impact.

[0023] Next, the vibrational energy is transferred to the connection structure between the support 3 and the base 1. When subjected to pressure, the polymer memory foam board 4 on the upper surface of the support 3 will further absorb energy through its own deformation, which has a good filtering effect, especially for high-frequency vibrations.

[0024] In the left-right direction, the lateral vibration caused by the earthquake will cause the support base 3 to displace, at which time the seismic anti-seismic mechanism 7 will play a buffering role. Since the left-right movement of the support rod 703 is restricted within the second splicing groove 6, the lateral displacement of the support base 3 will cause the slider 702 in the mounting groove 8 to slide within the limiting groove 701. The second spring 708 and the second damping rod 709 on the support rod 703 constitute a buffer structure in the left-right direction, and the second spring 708 and the second damping rod 709 on the other support rod 703 work on the same principle.

[0025] In the vertical direction, the up-and-down vibration of the support base 3 is transmitted to the seismic-resistant mechanism 7 through the splicing block 704. The splicing block 704 is slidably connected to the inner wall of the second splicing groove 6, and the first spring 705 and the first damping rod 706 on its bottom surface constitute a vertical buffer structure: when an earthquake generates vertical vibration, the support base 3 drives the splicing block 704 to move up and down in the second splicing groove 6, the first spring 705 is compressed or stretched, and the first damping rod 706 works synchronously to consume energy. The base plate 707 is slidably connected to the inner wall of the second splicing groove 6, providing support for the first spring 705 and the first damping rod 706 to ensure the stability of the vertical buffer. The first spring 705 and the first damping rod 706 on the other support rod 703 also work on the same principle.

[0026] During installation, firstly, the sliders 702 in the two limiting grooves 701 are simultaneously pushed inward, causing the support rod 703 to retract the splicing block 704 inward. Then, the support base 3 and the splicing block 704 are placed into the second splicing groove 6 of the base 1. At this time, the support base 3 is pressed down, and the splicing block 704 compresses the first spring 705 and the first damping rod 706. Due to the elastic force of the second spring 708, the slider 702 pushes the support rod 703, causing the splicing block 704 to unfold to both sides until the splicing block 704 is engaged at the bottom of the second splicing groove 6. At this time, the first spring 705 and the first damping rod 706 push the support base 3 upward through their elastic force to lock it in the second splicing groove 6, completing the installation and fixing.

[0027] The combination of this multi-level seismic-resistant mechanism 7 with the high-density rubber pad 2 and the polymer memory foam board 4 forms a rigid-flexible coupled composite buffer system. It can trigger the coordinated work of each buffer component through the multi-directional movement of the support seat 3 to achieve graded absorption and dissipation of seismic energy. At the same time, the modular splicing design ensures convenient installation and structural adaptability.
