Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a vibration isolation structure for building construction. Background Technology

[0002] Modern buildings face threats from various vibration sources. Heavy urban traffic generates vibrations that constantly impact surrounding buildings; construction machinery operations also affect nearby structures. Furthermore, natural disasters such as earthquakes pose significant challenges to building structural safety. Traditional building structures often have shortcomings in dealing with these vibrations. Their vibration damping capacity is limited, failing to effectively absorb and dissipate vibration energy, causing vibrations to be directly transmitted to the building itself. This results in the building structure bearing additional stress over a long period, accelerating structural aging and damage, and also negatively impacting the use of precision instruments and the comfort of occupants. Therefore, we are introducing a new vibration isolation structure for building construction. Utility Model Content

[0003] The main objective of this invention is to provide a vibration isolation structure for building construction, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A vibration isolation structure for building construction includes a base, with support plates arranged around the upper perimeter of the base. A mounting groove is provided in the center of the base, and guide grooves are provided on the left and right sides of the inner surface of the mounting groove. A vibration isolation device is movably installed inside the two guide grooves and the mounting groove. Four auxiliary devices are provided at the upper end of the base, and a mounting seat is provided at the upper end of the four auxiliary devices and the vibration isolation device. A building body is provided at the upper end of the mounting seat. A plurality of first springs are provided at the front, rear, left, and right ends of the mounting seat. A first damping rod is provided inside each of the plurality of first springs. The plurality of first springs and the first damping rods are fixedly connected to the four support plates respectively.

[0006] Preferably, the vibration isolation device includes a movable block, with guide blocks provided on the left and right sides of the outer surface of the movable block, four second springs provided at the lower end of the movable block, a second damping rod fixedly installed at the middle of the lower end of the movable block, and a support column fixedly installed at the upper end of the movable block.

[0007] Preferably, the upper end of the support column is fixedly connected to the middle of the lower end of the mounting base.

[0008] Preferably, the movable block is movably mounted on the inner surface of the mounting groove, and the movable block is movably mounted inside the guide groove via a guide block.

[0009] Preferably, the upper ends of the four auxiliary devices are fixedly connected to the four corners of the lower end of the mounting base.

[0010] Preferably, the auxiliary device includes a cylindrical sleeve, a fixing plate is fixedly installed on the middle of the inner surface of the cylindrical sleeve, a third spring is fixedly installed on the upper and lower ends of the fixing plate, a third damping rod is provided at the middle of the upper and lower ends of the fixing plate, a shock absorber rod is fixedly installed on the ends of the two third springs away from the fixing plate, and a connecting plate is provided on the ends of the two shock absorber rods away from the third springs.

[0011] Preferably, both shock absorber rods are fixedly connected to the upper end of the base and the lower end of the mounting base respectively via connecting plates.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When external vibrations are transmitted, the second spring and the second damping rod in the seismic isolation device take the lead in absorbing, buffering and dissipating the vibration energy, initially weakening the vibration amplitude. The third spring and the third damping rod of the auxiliary device further buffer and convert the vibrations from different directions. Finally, through the secondary buffering and energy dissipation of the first spring and the first damping rod, the vibration transmitted to the building body is greatly reduced, ensuring the stability of the indoor environment and reducing the damage to the building structure and internal facilities caused by vibration.

[0014] 2. Through the coordinated operation of various components such as the seismic isolation device, auxiliary devices, first spring, and first damping rod, the support column stably transmits vibration and support force. The auxiliary devices are tightly connected to the base and mounting base through damping rods and connecting plates, ensuring the stability of the entire structure during vibration. Each component performs its own function while cooperating with each other, enabling the mounting base to maintain relative stability during vibration, thereby ensuring the structural stability of the building and improving the safety and reliability of the building under various vibration environments.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A vibration isolation structure for building construction includes a base 1, with support plates 2 arranged around the upper end of the base 1. A mounting groove 3 is provided in the center of the base 1. Guide grooves 4 are provided on the left and right sides of the inner surface of the mounting groove 3. A vibration isolation device 5 is movably installed inside the two guide grooves 4 and the mounting groove 3. Four auxiliary devices 6 are provided at the upper end of the base 1. A mounting seat 7 is provided at the upper end of the four auxiliary devices 6 and the vibration isolation device 5. A building body 8 is provided at the upper end of the mounting seat 7. A plurality of first springs 9 are provided at the front end, rear end, left end and right end of the mounting seat 7. A first damping rod 10 is provided inside each of the plurality of first springs 9. The plurality of first springs 9 and the first damping rods 10 are fixedly connected to the four support plates 2 respectively.

[0025] In this embodiment, the vibration isolation device 5 includes a movable block 51. Guide blocks 52 are provided on the left and right sides of the outer surface of the movable block 51. Four second springs 53 are provided at the lower end of the movable block 51. A second damping rod 54 is fixedly installed at the middle of the lower end of the movable block 51. A support column 55 is fixedly installed at the upper end of the movable block 51. The upper end of the support column 55 is fixedly connected to the middle of the lower end of the mounting base 7. The movable block 51 is movably installed on the inner surface of the mounting groove 3. The movable block 51 is movably installed inside the guide groove 4 through the guide blocks 52.

[0026] Through the above scheme: when the building is subjected to vibration, the movable block 51 begins to move within the mounting groove 3. Since guide blocks 52 are provided on the left and right sides of the outer surface of the movable block 51, the guide blocks 52 will slide along the guide groove 4. The four second springs 53 at the lower end of the movable block 51 and the second damping rod 54 in the middle begin to function. The second springs 53 absorb and buffer the vibration energy by their own elastic deformation, reducing the vertical movement amplitude of the movable block 51. The second damping rod 54 converts the kinetic energy of the vibration into heat energy and other forms of energy and dissipates them through the internal damping mechanism, further suppressing the vibration of the movable block 51. The vibration after being buffered and damped by the second springs 53 and the second damping rod 54 is transmitted upward to the mounting base 7 through the support column 55. The support column 55 not only plays a connecting role, but also stably transmits the supporting force from below to the mounting base 7.

[0027] In this embodiment, the upper ends of the four auxiliary devices 6 are fixedly connected to the four corners of the lower end of the mounting base 7, respectively. The auxiliary device 6 includes a cylindrical sleeve 61, a fixing plate 62 is fixedly installed in the middle of the inner surface of the cylindrical sleeve 61, a third spring 63 is fixedly installed in the upper and lower ends of the fixing plate 62, a third damping rod 64 is provided in the middle of the upper and lower ends of the fixing plate 62, a shock absorber rod 65 is fixedly installed in the end of the two third springs 63 away from the fixing plate 62, and a connecting plate 66 is provided in the end of the two shock absorber rods 65 away from the third springs 63. The two shock absorber rods 65 are fixedly connected to the upper end of the base 1 and the lower end of the mounting base 7 through the connecting plate 66, respectively.

[0028] Through the above scheme: When the auxiliary device 6 is working, when vibration is transmitted from the base 1 or the mounting seat 7, the third spring 63 and the third damping rod 64 inside the cylindrical sleeve 61 start to operate. The third spring 63, located at the upper and lower ends of the fixed plate 62, provides initial buffering for the vibration from the base 1 and the mounting seat 7 respectively, using elastic force to offset part of the vibration energy. At the same time, the third damping rod 64 converts the remaining vibration energy into other forms of energy, further weakening the vibration amplitude. After the initial damping, the damping rod 65 transmits the processed vibration to the base 1 or the mounting seat 7 through the connecting plate 66. The two damping rods 65 are connected to the base 1 and the mounting seat 7 respectively. In the process of transmitting vibration, they rely on their own structural strength and the connection stability with the connecting plate 66 to ensure that the auxiliary device 6 and the entire structure work closely together to complete the vibration isolation task.

[0029] It should be noted that this utility model is a vibration isolation structure for building construction. During use, when external vibrations are transmitted, they directly act on the building body 8, and the vibrations are transmitted downwards through the mounting base 7. At the same time, due to the interaction between the building and the ground, the base 1 is also affected by vibrations. The vibrations transmitted from the mounting base 7 are transmitted to the movable block 51 of the vibration isolation device 5 through the support column 55. The four second springs 53 at the lower end of the movable block 51 absorb and buffer the vibration energy through elastic deformation, reducing the vertical movement amplitude of the movable block 51. The second damping rod 54 converts the vibration kinetic energy into heat energy and other forms of energy and dissipates it, further suppressing the vibration of the movable block 51. After buffering and damping, the vibrations are stably transmitted to the mounting base 7 through the support column 55. At the same time, when vibrations are transmitted from the base 1 or the mounting base 7, the third spring 63 and the third damping rod 64 inside the cylindrical sleeve 61 begin to operate. The third springs 63 at the upper and lower ends of the fixed plate 62 provide initial buffering for vibrations from the base 1 and mounting base 7, respectively, using elastic force to offset part of the vibration energy. The third damping rod 64 converts the remaining vibration energy into other forms of energy, further weakening the vibration amplitude. After the initial damping, the damping rod 65 transmits the processed vibration to the base 1 or mounting base 7 through the connecting plate 66, ensuring that the auxiliary device 6 works closely with the entire structure to collaboratively complete the vibration isolation task. The first spring 9 uses elasticity to provide secondary buffering for the vibration of the mounting base 7, while the first damping rod 10 converts and dissipates the vibration energy, further stabilizing the mounting base 7 and reducing its vibration amplitude, thereby comprehensively ensuring the vibration isolation effect of the building body 8.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
