Example

[0043] like Figure 1-2 As shown, an embodiment of the present invention provides a steel spring vibration isolator, comprising an upper docking assembly 1, a lower docking assembly 2, a main vibration isolation assembly 3 and an auxiliary vibration isolation assembly 4. The upper docking assembly 1 is arranged at the top of the isolation layer, and the lower docking assembly 2 is arranged at the bottom of the isolation layer. The main vibration isolation assembly 3 is arranged between the upper docking assembly 1 and the lower docking assembly 2, and its top is connected to the upper docking assembly 1, and its bottom is connected to the lower docking assembly 2, which serves as a buffering vibration isolation function. The auxiliary vibration isolation assembly 4 is arranged around the side of the main vibration isolation assembly 3, and its top is correspondingly connected to the upper docking assembly 1, and its bottom is correspondingly connected to the lower docking assembly 2, which serves as a buffering vibration isolation function.

[0044] In this embodiment, reference Figure 3-5The upper docking assembly 1 includes an upper embedded seat plate 101 and an upper base 107 arranged in an upper and lower body position. External buckle plates 103 are symmetrically installed on both sides of the bottom of the upper embedded seat plate 101, and internal buckle plates 104 are symmetrically installed on both sides of the top of the upper base 107. The external buckle plates 103 and the internal buckle plates 104 are both L-shaped, and the external buckle plates 103 and the internal buckle plates 104 correspond to each other. The cooperation between the external buckle plates 103 and the internal buckle plates 104 can enable the upper embedded seat plate 101 and the upper base 107 to be quickly docked. Furthermore, a rubber filling body 105 is provided between the upper embedded seat plate 101 and the upper base 107. The two sides of the rubber filling body 105 correspond to the inner sides of the external buckle plates 103 and the internal buckle plates 104. Through the filling of the rubber filling body 105, there is no longer a gap between the upper embedded seat plate 101 and the upper base 107 after docking, thereby improving the stability of the structure.

[0045] In this embodiment, reference Figure 3-5 The lower docking assembly 2 includes a lower base 205 and a lower embedded seat plate 201 arranged in the upper and lower body positions.

[0046] In this embodiment, reference Figure 6 The main vibration isolation assembly 3 includes an outer sleeve 301 installed in the middle of the bottom of the upper base 107, and a flange seat 303 provided in the middle of the top of the lower base 205. A plurality of second fastening bolts 304 are connected around the edge of the flange seat 303. The bottom ends of the second fastening bolts 304 are correspondingly installed on the top of the lower base 205. An inner sleeve 302 is installed in the middle of the top of the flange seat 303. Semi-ring hoops 305 are installed on both sides of the outer side of the inner sleeve 302 through third fastening bolts 306 to increase the outer diameter of the inner sleeve 302. An inner rubber ring 311 is sleeved on the outside of the semi-ring 305. An outer rubber ring 310 is sleeved on the outside of the inner rubber ring 311. The outer portion of the outer rubber ring 310 fits inside the outer sleeve 301. A lower rubber pad 313 is provided on the inside of the outer sleeve 301, close to the top of the outer rubber ring 310. An upper rubber pad 312 is provided on the top of the lower rubber pad 313. The top of the upper rubber pad 312 is close to the inner top of the outer sleeve 301.

[0047] In this embodiment, when the rail car passes, it is subject to the comprehensive influence of building structure, geological characteristics, etc., and after a long time of vertical vibration on the upper span building, it is also very easy to cause lateral vibration. At this time, with the cooperation of the above-mentioned structure, the lateral force between the outer sleeve 301 and the inner sleeve 302 is used to enable the vibration isolator to have the ability to cope with shear force. Specifically, when the inner sleeve 302 squeezes the inner wall of the outer sleeve 301, the collision and buffering between the semi-hoop 305 and the inner rubber ring 311 and the outer rubber ring 310 enable the building to have the ability to isolate lateral vibration. Further, referring to Figure 6By changing the number of half hoops 305 and adapting to inner rubber rings 311 of different thicknesses, the ability to isolate lateral vibrations can be changed, thereby better meeting building safety requirements.

[0048] In this embodiment, reference Figure 6 An outer steel spring 308 is provided inside the inner sleeve 302, and an inner steel spring 309 is provided inside the outer steel spring 308. The bottom of the outer steel spring 308 is located inside the inner sleeve 302 and a lower rubber seat 307 is provided. The bottom of the lower rubber seat 307 is tightly attached to the inner bottom end of the inner sleeve 302. The top of the outer steel spring 308 is located inside the inner rubber ring 311 and an upper rubber seat 314 is provided. The top of the upper rubber seat 314 is tightly attached to the bottom of the lower rubber pad 313.

[0049] When the rail car passes and causes vertical vibration to occur in the upper span building, the outer sleeve 301 limits and guides the inner sleeve 302, so that the outer steel spring 308 and the inner steel spring 309 can achieve isolation from the vibration during the process of releasing and increasing elastic potential energy. Furthermore, the upper rubber pad 312, the lower rubber pad 313, the upper rubber seat 314 and the lower rubber seat 307 increase the vibration isolation effect.

[0050] In this embodiment, reference Figure 7 The auxiliary vibration isolation assembly 4 includes multiple upper column seats 401 and multiple lower column seats 403 correspondingly arranged below the upper column seats 401. The multiple upper column seats 401 are evenly arranged around the side of the main vibration isolation assembly 3, and their tops are correspondingly installed on the bottom of the upper base 107, and the bottoms of the lower column seats 403 are correspondingly installed on the top of the lower base 205. An inner rod 402 is installed in the middle of the bottom of the upper column seat 401, and the outside of the inner rod 402 is equipped with an outer tube 404. The bottom end of the outer tube 404 is correspondingly installed in the middle of the top of the lower column seat 403, and the outside of the combination of the inner rod 402 and the outer tube 404 is covered with an auxiliary steel spring 405.

[0051] Through the limiting guidance of the inner rod 402 by the outer tube 404 in the auxiliary vibration isolation assembly 4, the auxiliary steel spring 405 can achieve vibration isolation during the process of releasing and increasing elastic potential energy, thereby helping to improve the working effect of the spring vibration isolator.

[0052] Furthermore, a plurality of anchor bars 102 are evenly installed on the top of the upper embedded seat plate 101. The anchor bars 102 are used to connect and tie with the steel bars of the building structure, thereby forming a whole by pouring concrete.

[0053] In this embodiment, again referring to Figure 3-4A plurality of through-connecting bolts 106 are evenly arranged on the upper part of the rubber filling body 105. The two ends of the through-connecting bolts 106 respectively penetrate the outer buckle plates 103 on both sides and are fastened by nuts. The four corners of the upper base 107 are provided with first fastening bolts 108. The top end of the first fastening bolt 108 penetrates the rubber filling body 105 and is correspondingly connected to the inside of the upper embedded seat plate 101.

[0054] Furthermore, a plurality of embedded bolts 202 are evenly interspersed around the lower embedded seat plate 201. The top ends of the embedded bolts 202 pass through the lower base 205 and are fastened by nuts. The bottom ends of the embedded bolts 202 are extended to the bottom of the lower embedded seat plate 201. The extended parts of the embedded bolts 202 are used to connect and tie with the steel bars of the building structure, thereby becoming one by pouring concrete.

[0055] In this embodiment, again referring to Figure 4-5 A plurality of limit pins 203 are installed on the top of the lower embedded seat plate 201, and a plurality of pin holes 204 corresponding to the limit pins 203 are provided at the bottom of the lower base 205. The limit pins 203 and the pin holes 204 can facilitate the rapid docking between the lower embedded seat plate 201 and the lower base 205.

[0056] Compared with the existing spring isolator technology, this technical solution has the ability to be quickly disassembled and assembled with the building structure after installation, thereby improving its applicability. Specifically, first, the isolator to be disassembled is lifted by a jack to ensure the safety of the structure after disassembly, and then the first fastening bolt 108 and the through-connecting bolt 106 are removed, and then the rubber filler 105 is taken out, and the fastening between the embedded bolt 202 and the lower base 205 is released, and then the upper base 107, the lower base 205 and the structure between the two are lifted upward as a whole until the limit pin 203 is disengaged from the pin hole 204, and the lower base 205 is disengaged from the embedded bolt 202, and finally the above-mentioned combination is withdrawn along the trajectory of the outer buckle plate 103 and the inner buckle plate 104 to realize the disassembly of the vibration isolator.

[0060] Step 3: Install the formwork, and then pour concrete into the formwork cavity. After solidification, the lower structural column 6, the lower pier 8, the lower embedded seat plate 201, and the embedded bolts 202 form a whole.

[0061] Step 4: Assemble the lower base 205 and the lower embedded seat plate 201 through the cooperation of the limiting pin 203 and the pin hole 204, and fasten the lower base 205 and the lower embedded seat plate 201 through the embedded bolt 202.

Fasten the rubber filler 105 to the anchor bar 102 and the outer buckle plate 103 through the penetrating connecting bolt 106, and fasten the rubber filler 105 to the upper base 107 through the first fastening bolt 108, while strengthening its connection with the upper embedded seat plate 101.

[0064] Step 8: Connect the lower part 10 of the limit column to the lower support.

[0065] Step nine: Place multiple upper piers 7 on the upper embedded seat plate 101, and tie the anchor bars 102 to the upper piers 7.
