[0001] The present invention relates to the field of shock absorption technology, and more specifically, to a combined rubber shock absorption device and a construction method thereof. Background Art

[0002] Earthquakes are a large-scale natural disaster that can cause great damage to building structures. Combined rubber shock-absorbing devices can reduce the energy transmitted to building structures by earthquake vibrations through their elastic properties and energy absorption capacity, thereby significantly reducing the damage caused by earthquakes.

The shock absorbing device effectively absorbs the energy carried by the deformation of the spring when the shear wave acts on the earthquake through the upper and lower annular rubber baffles, which can effectively buffer the impact of the instantaneous earthquake shear wave. At the same time, the rubber annular baffle on the lower rubber annular baffle is set around the steel spring to avoid the mutual influence of adjacent steel springs during operation, greatly enhancing the safety of super high-rise buildings and the living comfort of high-rise residents. However, the shock absorbing device has the following defects.

[0031] The working principle of the combined rubber shock absorbing device of the present invention is as follows: Step 1: When locking the combination, insert the grouting main column 1 into the pre-buried space of the building body, and install multiple auxiliary grouting columns 11 in other pre-buried holes respectively, and then move multiple linkage rings 23 upward, and the linkage rings 23 are docked along the outer wall of the auxiliary grouting column 11. At the same time, the positioning ring 24 is slidably docked on the outer wall of the grouting main column 1, and the positioning ring 24 is also slidably docked on the outer wall of the positioning block 32.

[0032] Step 2. When grouting is used, a grouting pump pipe is inserted into the grouting pipe 18, and a grouting pump pipe is inserted into the top of multiple auxiliary grouting columns 11, so that outflow grouting can be achieved through multiple holes outside the grouting main column 1, and outflow grouting can be achieved through multiple holes on the auxiliary grouting columns 11. After grouting, wait for it to solidify, and then press the building body onto the upper surface of the buffer sleeve 19.

[0033] Step three, during fluctuation detection, when the grouting main column 1 vibrates, the grouting main column 1 will drive the support ring 2 to vibrate, the support ring 2 carries multiple support sleeves 3 to vibrate, the support sleeve 3 drives the hinged column 4 to vibrate, the hinged column 4 carries the connecting shaft 5 to vibrate, the connecting shaft 5 drives the sleeve rod 6 to vibrate, and the sleeve rod 6 can make the limit shaft 7 drive the sleeve rod 8 to vibrate, the sleeve rod 8 drives the support shaft 9 to vibrate, the support shaft 9 vibrates, and the sleeve shaft 10 carries the auxiliary grouting column 11 to vibrate, so that the limit shaft 7 can drive the support block 13 to move back and forth, the support block 13 drives the sliding column 14 to move back and forth, the sliding column 14 moves back and forth along the inside of the sleeve block 17, and the sleeve plate 12 supports the sleeve block 17, and the sliding column 14 carries the limit block 15 to move back and forth, the limit block 15 drives the distance sensor 16 to move back and forth, and the distance sensor 16 senses the distance between the distance sensor 16 and the sleeve block 17. When the sensed value is the same as the fluctuation value set by the wireless controller 22, it is known that the vibration fluctuation value range between the grouting main column 1 and the multiple auxiliary grouting columns 11 is within the qualified range. If they are different, the fluctuation value range is abnormal, so it is necessary to repair the shock absorption state of the grouting main column 1 and the multiple auxiliary grouting columns 11.

[0034] Step 4: During displacement detection, the vibration of the grouting main column 1 will drive the positioning block 32 to vibrate, the positioning block 32 drives the positioning ring 24 to vibrate, the positioning ring 24 drives multiple connecting blocks 29 to vibrate, the connecting block 29 carries the limit support block 28 to vibrate, the limit support block 28 carries the guide slide 27 to vibrate, the guide slide 27 slides back and forth along the inner wall of the sliding sleeve 26, the guide slide 27 carries the support block 31 to slide back and forth, and the auxiliary grouting column 11 drives the linkage ring 23 to vibrate, the linkage ring 23 drives the slider 25 to vibrate, and the slider 25 drives the sliding sleeve 26 to achieve left and right reciprocating movement. The distance between the infrared distance sensor 30 and the slider 25 is sensed by the infrared distance sensor 30. When the displacement value sensed is within the range value set by the wireless controller 22, it is known that the vibration is within the qualified range. If it exceeds the set range, there is a construction problem in the bottom vibration range of the auxiliary grouting column 11 and the grouting main column 1, which needs to be reinforced or repaired.

The combined rubber shock absorbing device according to claim 7, characterized in that: The combined locking assembly comprises a positioning block (32) fixedly connected to one side of the inner wall of the positioning ring (24); The top end of the positioning block (32) is fixedly connected to a support plate (33), and the bottom end of the support plate (33) is fixedly connected to a push electric cylinder (34), and the output end of the push electric cylinder (34) is fixedly connected to a plug-in positioning block (35); A linkage block (36) is fixedly connected to the upper surface of the plug-in positioning block (35), and a sliding bar (37) is fixedly connected to one side of the linkage block (36), and the sliding bar (37) is slidably connected to the support plate (33).

9. The combined rubber shock absorbing device according to claim 8, characterized in that: The plug-in positioning block (35) is slidably plugged into the positioning ring (24), and the outer wall of the plug-in positioning block (35) is configured as a smooth surface.

10. A construction method of a combined rubber shock absorbing device, using the combined rubber shock absorbing device according to any one of claims 1 to 9, characterized in that: The method comprises the following steps: Step 1: Combination locking: insert the grouting main column (1) into the pre-buried space of the building body, and then install multiple auxiliary grouting columns (11) in multiple other pre-buried spaces respectively, push the electric cylinder (34) to push the plug-in positioning block (35) to move left, and the plug-in positioning block (35) enters the interior of the positioning ring (24), and the positioning ring (24) and the positioning block (32) are connected and locked; Step 2: grouting, by inserting a grouting pump tube into the grouting tube (18), inserting the grouting pump tube into the top of the plurality of auxiliary grouting columns (11), and supplying pressure to complete the grouting operation; Step 3: Fluctuation detection: when the grouting main column (1) vibrates, the limit shaft (7) drives the support block (13) to move back and forth. When the sensed value is the same as the fluctuation value set by the wireless controller (22), the vibration fluctuation value range between the grouting main column (1) and the plurality of auxiliary grouting columns (11) is known; Step 4: displacement detection. The vibration of the grouting main column (1) drives the positioning block (32) to vibrate, and the slider (25) drives the sliding sleeve (26) to achieve left and right reciprocating movement. If the displacement value of the sensor is within the range value set by the wireless controller (22), it is known that the vibration is within the acceptable range value.
