Description

  The present invention relates to the field of vibration and noise control, and more particularly, to a vibration isolator that is mounted in a floating slab of a track and reduces the influence of defects caused by vibration and noise generated during operation of the track vehicle.

  With the progress of social development and science and technology, the development of city trajectory is increasing in large and middle cities, and the construction of city trajectories, especially the construction of subways, is being carried out one after another. In order to reduce the impact on the buildings above and around the track and the residents, installing a floating roadbed in a special section is one of the important vibration isolation measures in subway design. Conventionally, a vibration isolator on a floating roadbed is mainly divided into an interior type and a side type depending on the mounting form.

  In the conventional internal vibration isolator, it is necessary to fix the connecting movable sleeve in the floating slab in advance. For example, Patent Document 1 discloses that a supporting block fixedly installed on the connecting movable sleeve is directly connected during operation. A floating road bed supported by a spring vibration isolator is disclosed as a member for receiving force. Currently, as a standard in the field, the design life of a floating slab is required to be at least 100 years. Within such a long period of time, the connecting movable sleeve made of ordinary carbon steel (for example, Q235 or Q345) is subject to fatigue fracture, weld cracking at the main force receiving site due to the action of corrosion and alternating stress. Defects such as reduction of wall thickness due to rust occurred.

  However, since the connecting movable sleeve is already integrated with the floating slab, it cannot be exchanged directly. Also, on-site maintenance was very difficult due to the limitation of the space and the internal space of the connecting movable sleeve. In addition, when performing maintenance, it was necessary to stop the operation of the vehicle for a long time, which caused inconvenience to the use of orbital traffic for citizens, and the operating company also suffered economic losses and adversely affected the daily life of the city. It was. In addition, the vibration isolator adopting such a configuration requires the entire thickness of the connecting movable sleeve to be equal to the thickness of the floating slab regardless of the thickness of the floating slab, and the material consumption is high. .

  Further, in the conventional internal vibration isolator, in order to perform normal maintenance / replacement of the elastic vibration isolator, a technique has been adopted in which the elastic vibration isolator can be directly taken out through the through hole of the connecting sleeve. For this reason, the size of the through hole must be larger than that of the elastic vibration insulator, and the connecting sleeve is also increased in size accordingly, occupying a larger space, and not advantageous for cost reduction.

ZL200410035441.1

  One of the objects of the present invention is to solve the above-mentioned defects, adopting a movable sleeve that can be taken out, inspected and repaired and exchanged, the height of the movable sleeve, and the size of the through hole thereof. SUMMARY OF THE INVENTION It is an object of the present invention to provide an internal vibration isolator that is not subject to severe restrictions on the thickness of the floating slab and the size of the elastic vibration isolator.

The interior vibration isolator according to the present invention has a movable sleeve installed in an elastic vibration isolator, a support block installed in the movable sleeve, a through hole is opened in the center of the support block, and the elastic vibration isolator is supported. A flange that protrudes outward from the lower part of the movable sleeve and that projects outwardly is configured symmetrically. When used, it is possible to support the member to be vibration-isolated by the elastic vibration isolator by engaging the flange extended to the outside of the movable sleeve with the member to be vibration-isolated.
Further, in order to easily carry out the lifting, a through-hole may be opened at the center of the movable sleeve, and an abutment block positioned above the support block may be installed.
In addition, in order to easily adjust the altitude and the level, a washer having a through hole opened at the center thereof may be installed between the elastic vibration isolator and the support block. In order to smoothly adjust the number of washers or the overall thickness from above, the size and shape of the central opening of the support block and / or the abutment block should be balanced with the washer. Overlap is realized by the displacement of the support block. In some cases, the washer is not used by directly supporting the elastic vibration isolator on the movable sleeve.
In the present invention, since the movable sleeve can be taken out at any time, the elastic vibration isolator can be taken out without passing through the central opening of the supporting block and / or the contact block. When taking out the elastic vibration isolator, the movable sleeve is taken out first, and then the elastic vibration isolator is taken out. Of course, when the elastic vibration insulator is inserted or taken out directly from above according to the demand of the process, the size and shape of the central opening of the support block and / or the contact block may be matched with the size of the elastic vibration insulator. When a washer is not used, it must be ensured that the upper surface of the elastic vibration isolator is at least overlapped with the supporting block by being displaced. The contact block or support block of the present invention may have a plurality of block-like configurations installed in a split body, or may have an integrated ring-like configuration.

  Based on the above-described principle, the movable sleeve of the internal vibration isolator according to the present invention may be simplified to one support stopper. An elastic vibration isolator is positioned below the support stopper, and an adjustment bolt is inserted through the center of the support stopper. When using, by adjusting the adjustment bolt, the plate part or corner at the end of the support stopper is used as a flange to lock the member to be subject to vibration insulation. A member to be insulated can be received. Alternatively, at least two flanges extending outward in the horizontal direction at the periphery of the support stopper are installed, and the flange and the member to be vibration-insulated are locked to vibrate by the elastic vibration insulator. A member to be insulated can be received.

  Further, the elastic vibration isolator employed in the interior vibration isolator of the present invention includes many types. For example, a steel spring vibration insulator, a rubber vibration insulator, an air suspension vibration insulator, and the like can be given. Among these, screw steel springs, disk springs, rubber and metal composite springs are employed as elastic elements, and elastic materials such as rubber are also used. The elastic vibration insulator may be provided with a liquid damping material such as silicone oil and a solid damping material such as rubber at the same time.

  Another object of the present invention is to provide a floating road bed having an interior vibration isolator. The floating roadbed having the interior vibration isolator of the present invention includes a vibration isolator and a floating slab. The floating slab is provided with a stepped through hole, and a shoulder is formed at the boundary between the upper through hole and the lower through hole. The inner diameter of the through hole above the shoulder is smaller than the inner diameter of the lower through hole, the size of the upper through hole and the movable sleeve is balanced, and the flange of the movable sleeve can be overlapped by the shoulder and misalignment, The vibration isolator is disposed at a lower portion of the through hole, and an upper end of the movable sleeve or a flange installed on the movable sleeve is supported by a shoulder in the through hole.

  Still another object of the present invention is to provide a floating roadbed having an interior vibration isolator. A floating roadbed having such an internal vibration isolator includes a vibration isolator and a floating slab, and the floating slab is provided with a spare through hole, the spare through hole being balanced with the size of the movable sleeve, and the flange of the movable sleeve being a spare. It can be overlapped with the bottom surface of the floating slab at the bottom of the through-hole by misalignment, part of the internal vibration isolator is placed in the preliminary through-hole, and the flange installed in the movable sleeve is on the bottom surface of the floating slab It is supported.

  In the configuration of the floating road bed according to the two present inventions described above, the shape of the preliminary through hole provided in the floating slab is any of a triangle, a rectangle, a rectangle, a polygonal column, an ellipse, and a circle having a symmetric notch. It may be.

  Further, the flanges provided on the movable sleeve of the internal vibration isolator are arranged symmetrically. The symmetry mentioned here includes axial symmetry or central symmetry. A bush can be added in the preliminary through hole so that the structure of the preliminary through hole that balances the movable sleeve of the floating slab is not damaged. In order to ensure a standard life of 100 years, the bushing is made of a corrosion-resistant and durable material.

The bush may be made of a metal material such as stainless steel, aluminum alloy, carbon steel subjected to good corrosion resistance treatment, and engineering bush, ceramic, hard rubber, glass fiber reinforced plastic, precast concrete, etc. It may be made of a nonmetallic material having sufficient strength and durability. Further, it may be made of a composite material of metal and nonmetal according to the external force actually received. For example, a steel plate that protects the ceramic is used for the shoulder that performs locking in the vibration isolator, and a rubber material having a steel skeleton is used for the portion on the side wall of the preliminary through hole. The bushes are constructed by combining them together by sulfuration treatment.
When used, the bush is disposed on at least a part of the inner wall surface of the preliminary through hole of the floating slab, the bush and the floating slab are integrated in advance, and at least a part of the movable sleeve is disposed in the bush. Of course, in order to reduce material consumption and reduce costs, it is possible to obtain an effect that the bush may be simplified to a back plate that is used only for the shoulder for engaging the vibration isolator. . Similarly, a metal material such as steel, stainless steel, and aluminum alloy can be adopted as the back plate, and it can be made of a non-metallic material having a predetermined strength such as engineering plastic, ceramic, glass fiber reinforced plastic, and hard rubber. Good.

  In addition, in order to lift the floating slab from above the floating slab more easily and adjust its height and level, a contact block is installed on the inner wall of the preliminary through hole of the floating slab, and the elastic vibration insulator and the movable sleeve A washer is installed between the support block, the contact block is positioned above the support block of the movable sleeve, and a contact through hole is opened at the center of the washer. In order to smoothly adjust the number of washers or the overall thickness from above, the central opening and shape of the support block and the abutment block are balanced with the size of the washer. Wrapped. In applications where the individual elastic vibration isolator is in direct contact with the movable sleeve without the use of a washer, the central opening of the support block and the abutment block is used to insert or remove the elastic vibration isolator directly from above. The size and shape of the elastic vibration insulator are balanced with the size of the elastic vibration insulator, and the upper surface of the elastic vibration insulator is overlapped by at least the support block due to the displacement.

  In the floating road bed provided with two interior vibration isolation devices according to the present invention, the abutment block or the support block may have a plurality of block-like configurations installed in a split body, or one integrated ring shape It may be configured as follows.

  In order to prevent the elastic vibration isolator from sliding in the horizontal direction, a connecting device for preventing horizontal displacement of the elastic vibration isolator is installed on the upper and lower surfaces, and the upper connecting device is connected to a washer or a support block. The lower connecting device is connected to the ground. The connecting device is any one of a non-slip plate, a bolt, and an uneven structure.

  Further, in order to ensure effective locking of the movable sleeve, the movable sleeve is provided with position limiting means at a locking portion with the bush or the preliminary through hole, and the position limiting means is a position limiting block or a position limiting groove. The position limiting direction is any one of the axial direction, the circumferential direction, and the radial direction of the through hole, or a combination of these directions.

  In the present invention, a movable sleeve (or support stopper) that can be quickly removed is installed, so that the connection relationship between the movable sleeve (or support stopper) and the floating slab is separated from the conventional integral fitting fixed connection. Therefore, the movable sleeve (or support stopper) on which the force receiving element is installed can be quickly taken out for inspection and repair or replacement.

  For example, the movable sleeve can be maintained or replaced using the normal inspection time when the track vehicle is in operation. Furthermore, after the movable sleeve (or support stopper) is installed on the floating slab and the body, its altitude can be optimized according to the demand for mounting and is not affected by the thickness of the floating slab. In particular, when the floating slab is thick, the effect of reducing material consumption and reducing costs is remarkable.

  In addition, the movable sleeve can be taken out at any time, and the elastic vibration insulator below the movable sleeve does not need to be inserted and removed from the through-hole installed in the movable sleeve. It becomes advantageous to cost reduction. In addition, a bush is added in some technical proposals of the present invention, but during use, only the engaging part of the bush with the movable sleeve receives a large pressure. Is made of a thin metal plate in a portion where the thickness is extremely small or unacceptable, and thus made of a non-metallic material. The bushing can be further simplified directly to the back plate and has little impact on the overall cost of the product.

  In the present invention, another advantage of adopting the removable movable sleeve configuration is that the movable sleeve that is separably locked is used, so that the force receiving portion due to the locking of the floating slab is greatly moved to the lower part. For a thin floating slab, the movable sleeve is further directly locked to the bottom surface of the floating slab. In this manner, the shear stress and punching resistance of the floating slab are greatly increased, the force receiving state is remarkably improved, and it is advantageous for protecting the floating slab body, and its service life is extended.

  Based on the above-described principle, the interior vibration isolation device of the present invention can be applied to vibration isolation to a floating road floor, and can also be applied to vibration isolation to areas such as the ground of construction and the foundation of equipment. It is possible to satisfy the requirements for the service life.

  In short, the interior vibration isolator of the present invention has a compact configuration, simplifies maintenance, improves the effect of vibration insulation, widens the application range, controls vibration of urban orbital traffic, and It is also widely applied to vibration isolation to the foundation of equipment. In addition, the floating road bed equipped with the interior vibration isolator of the present invention is easier to maintain, and can meet the requirement that the service life of the entire system be 100 years by replacing the movable sleeve. The prospects for are as bright as possible.

Example 1
The internal vibration isolator of the present invention shown in FIGS. 1 and 2 includes a movable sleeve 1 and an elastic vibration isolator 3. The elastic vibration insulator 3 according to the present embodiment is a screw steel spring vibration insulator having a liquid damping material installed therein, and a support block 2 is provided on the movable sleeve 1, and the elastic vibration insulator 3 is a support block. Four flanges 4 are provided horizontally at the lower part of the movable sleeve 1 and project outwardly. A washer 5 is provided between the support block 2 and the elastic vibration isolator 3 in order to adjust the height and level of a member that is an object of vibration insulation conveniently from above, and a through hole is formed in the center of the washer 5. Is provided.
The washer 5 is configured to have a size that can be penetrated from the central through hole of the support block (that is, the size is balanced), and realizes an overlap due to a positional deviation after the support block 2 is rotated. To be able to. FIG. 2 shows a state in which the two positions are overlapped.

  Further, when used as a track floating slab, as shown in FIGS. 3 and 4, preliminary floating holes 7 corresponding to the outer shape of the vibration isolator are provided in the floating slab 6 in advance. The preliminary through-hole 7 is configured as a step-shaped through-hole having a small cross-sectional area at the upper stage and a large cross-sectional area at the lower stage. In addition, an axial position limiting block 40 is provided in the through hole. Then, the elastic vibration insulator 3 and the movable sleeve 1 are sequentially introduced, and the washer 5 is installed in the central through hole of the support block 2. Thereafter, the flange 4 is compressed with respect to the elastic vibration insulator 3 by an external pressure tool until it becomes lower than the shoulder A of the preliminary through-hole 7. In this case, the axial position limiting block 40 supports the movable sleeve upward, and when the elastic vibration insulator 3 is subsequently compressed as shown in FIGS. 5 and 6, the washer 5 is completely supported. Then, the movable sleeve 1 is rotated by about 45 °, and the washer 5 and the support block 2 and the flange 4 and the shoulder A of the movable sleeve 1 are overlapped due to misalignment. After the execution of the pressure by the external pressure device is stopped, the elastic vibration insulator 3 rebounds, the washer 5 and the support block 2, the flange 4 and the shoulder A are brought into contact with each other, and the floating slab 6 is elastically elastically vibrated. Supported by the insulator 3. When the number of installed spring vibration isolators is sufficient, the floating slab 6 is detached from the surface of the ground 12 and floated, and a floating roadbed provided with the interior vibration isolators of the present invention is configured.

  If the floating slab 6 cannot be adjusted to an appropriate altitude or level by one washer 5, the added washer is installed in the central through hole of the support block 2 according to the method described above, and the pressure tool is used. The pressure is directly applied to the elastic vibration insulator through the through hole provided in the center of the washer so that the added washer is completely lower than the supporting block. In this case, the added washer is rotated by about 45 °, and the added washer also realizes overlap with the support block due to displacement, the pressure is stopped, the elastic vibration insulator is rebounded, and the washer is Is brought into contact with the support block. In this way, the overall thickness of the washer is adjusted until the floating slab reaches the appropriate height and level. Of course, the elastic vibration isolator may be directly supported by the supporting block without installing a washer.

  When the movable sleeve and the elastic vibration insulator are inspected, repaired or replaced, the elastic vibration insulator 3 is first compressed using an external jack to release the contact between the flange 4 and the shoulder A. The movable sleeve 1 is rotated by 45 ° so that the flange 4 and the shoulder A are not displaced and overlapped, and the upper through hole and the movable sleeve 1 are balanced. Then, the external jack is released, the elastic vibration insulator 3 rebounds, and each member is not subjected to force. As described above, the movable sleeve 1, the washer 5, and the elastic vibration insulator 3 are sequentially taken out from the preliminary through hole, and are simply inspected and repaired or replaced.

  Further, in order to prevent the elastic vibration insulator 3 from sliding in the horizontal direction, an anti-slip plate 11 having a very high friction coefficient is installed between the elastic vibration insulator 3 and the ground 12. Further, in order to prevent foreign matter from falling into the preliminary through-hole of the floating slab, the cover 13 is disposed on the upper portion of the preliminary through-hole. In order to reinforce the sealing effect and prevent rainwater or dust from entering, a seal gasket can be installed around the cover. The cover may be configured to be fit-in, and it is easily realized that the upper surface of the cover is flush with the surface of the floating slab.

  In the present embodiment, the case where four flanges 4 are provided has been described as an example. However, in an actual application, the number of flanges can be increased or decreased depending on the demand for space and load. However, usually at least two must be installed. Moreover, in order to ensure the stability of support, three or more are preferable.

  According to the present invention, the shape of the central through hole of the movable sleeve may be a shape such as a triangle, a trapezoid, an ellipse, and a rectangle in addition to the shape in the embodiment. If the shape of the through hole is balanced, the same effect can be realized even if the shape of the washer is changed. Further, the material of the washer in the present invention is not limited to the solid plate material. When the thickness of the floating slab is large, if the strength is sufficient, the same effect can be realized even if the washer is configured in various forms such as a hollow box or a barrel having flanges at both ends.

  Further, the preliminary through hole provided in the floating slab may be any one of a triangle, a square, a rectangle, a polygonal column, and an ellipse other than the circular through hole having the symmetrical notch shown in the present embodiment. There may be. Alternatively, other shapes having symmetrical notches may be used. If a movable sleeve, a washer, and an elastic vibration isolator corresponding to the above shape are installed, the same effect can be realized.

  In addition to the steel spring vibration insulator of this embodiment, various types of elastic vibration insulators such as rubber vibration insulators or air elastic vibration insulators are used as the internal vibration isolator of the present invention. Among these, screw steel springs, disk springs, rubber and metal composite springs are employed as elastic elements, and elastic materials such as rubber are also used. Further, the elastic vibration isolator is simultaneously provided with another liquid damping material such as modified asphalt or a solid damping material such as rubber.

  In addition, since concrete has a lifespan of 100 years or more and there are no members that are easily fixed and corroded in the floating slab, the movable sleeve made of carbon steel is rusted even if the life of the movable sleeve is 100 years or less. It can be replaced, and therefore, through the replacement of components as appropriate, the requirement that the overall service life of the system can reach 100 years can be met.

  Based on the above-described principle of the present embodiment, the interior vibration isolation device of the present invention can be applied to vibration isolation of a floating road floor, and can also be applied to vibration isolation of building grounds, equipment foundations, and the like. it can.

(Example 2)
The present invention shown in FIGS. 7 and 20 is a floating road bed provided with an interior vibration isolator, and differs from the first embodiment in the following points. That is, when the floating slab 6 to be vibration-insulated is very thin and it is impossible to provide a shoulder for locking by installing a stepped preliminary through hole, a spare of the same diameter is provided in the floating slab 6. The through hole 7 is installed, and the flange 4 is used to support the bottom surface around the preliminary through hole of the floating slab 6 so as to be directly locked. Take the load from 6. The elastic vibration insulator 3 in this embodiment is a screw steel spring damper in which a rubber solid damping material is disposed. Further, in order to smoothly achieve the engagement between the flange 4 and the bottom surface of the floating slab 6, a concrete base 19 is installed in advance on the surface of the ground 12, and the floating slab 6 is supported by the concrete base 19. The floating slab 6 is separated from the surface of the ground 12 by a predetermined distance so as to ensure a sufficient arrangement space for locking.

  Naturally, the altitude of the concrete base 19 can be determined by calculation, and when the floating slab 6 is placed in a floating state while ensuring that the locking space between the flange 4 and the bottom surface of the floating slab 6 is reserved in advance. The concrete base 19 cannot contact and interfere with the floating slab 6. Based on this principle, when the floating slab 6 is cast and formed, some protrusions such as a concrete base 19 may be installed on the floating slab, and the same effect can be obtained.

  In addition, as in Example 1, the life of the movable sleeve made of carbon steel in this example is 100 years or less. However, since the rusted movable sleeve can be taken out from the through hole and replaced, the replacement can be made in a timely manner. In this way, it is possible to satisfy the requirement that the total service life of the system reaches 100 years.

(Example 3)
As shown in FIG. 8, the present embodiment is different from the first embodiment in the following points. That is, the used internal vibration isolator has the contact block 9 on the movable sleeve 1 in order to easily adjust the altitude and level of the floating slab 6 from above. The central opening of the abutment block 9 should be balanced in size and shape with the size of the washer 5, and is a complicated opening shape consisting of all triangles and circles, and is point-symmetric with respect to 120 °. The contact block 9 is located above the support block 2.

  When applied to a floating roadbed having the interior vibration isolation device of the present invention, the movable sleeve on the target vibration isolation member is used to avoid inconvenience caused by installing a special through hole having a special shape in the floating slab. A bush 8 is added in the preliminary through hole so that the structure of the preliminary through hole that balances with the damage is not damaged. The preliminary through hole is a square two-stage through hole having a small cross-sectional area at the upper stage and a large cross-sectional area at the lower stage. Corresponding bushes 8 are also provided in the same shape, and the bushes 8 are subjected to rust prevention treatment. Made of steel plate. Further, since the shoulder B is engaged with the flange 4 and receives a force when the apparatus is operated, a thick steel plate is adopted as a part of the shoulder B. Further, in order to ensure that the relative position does not change after the flange 4 is engaged with the shoulder B, an engaging groove comprising the position limiting block 10 is provided at a corresponding position of the shoulder B. Further, in order to prevent the elastic vibration insulator 3 from moving horizontally, a plurality of tapered protrusions 14 are formed on the bottom of the elastic vibration insulator 3 by overlay welding, and the washer 5 and the elastic vibration insulator 3 An anti-slip plate 11 is installed between the two.

  As a specific application form, as shown in FIGS. 8 and 9, after the bush 8 and the floating slab 6 are integrally formed in advance, the elastic vibration insulator 3 and the movable sleeve 1 are sequentially put into the bush 8. The washer 5 is left in the central through hole of the support block 2. When inserting the movable sleeve 1, in order to insert the flange 4, as shown in FIG. 9, the flange 4 is inserted along the diagonal direction of the bush opening, and the movable sleeve 1 is rotated by about 45 ° to shoulder. To achieve overlap. In the case of lifting and mounting, as shown in FIG. 10, the support frame 16 and the contact block 9 are combined to provide a support point, and the hydraulic jack 15 is driven to apply pressure so that the washer 5 is The elastic vibration insulator 3 is compressed until it becomes lower than the support block 2, and the washer is rotated by 60 ° to realize overlap due to the positional deviation from the support block 2. Thereafter, the hydraulic jack 15 is released, the lifting support frame 16 and the hydraulic jack 15 are removed, the elastic vibration insulator 3 rebounds, and the washer 5, the support block 2, the flange 4, and the shoulder B are pressed against each other.

  In this case, as shown in FIG. 11, the washer 5 and the support block 2 are overlapped due to misalignment, and the flange 4 is fitted into a locking groove formed by the position limiting block 10. Thus, as shown in FIG. 12, the floating slab 6 is elastically supported by the elastic vibration insulator 3, and when the number of the elastic vibration insulators 3 is sufficient, the floating slab 6 is removed from the surface of the ground 12. A floating road bed that is detached and floated and includes the internal vibration isolator of the present invention is formed. In order to better prevent rainwater and dust from entering, a cover 13 and a seal gasket 17 are disposed in the preliminary through hole. Further, by controlling the size of the locking groove formed by the position limiting block 10, the movement of the movable sleeve in the circumferential direction in the preliminary through hole can be restricted, and the movement of the preliminary through hole in the radial direction can also be performed. Can be limited.

  When carrying out inspection / repair or replacement for the movable sleeve and the elastic vibration isolator, the elastic vibration isolator 3 is first compressed using the hydraulic jack 15 and the lifting support frame 16, and the washer 5 and the supporting block are compressed. 2 and the washer 5 are rotated by 60 °, so that the washer 5 and the support block 2 are not overlapped with each other so that both are balanced. Then, the hydraulic jack 15 is opened, the elastic vibration insulator 3 rebounds, and each member does not receive force. Thereby, the movable sleeve 1, the washer 5, and the elastic vibration isolator 3 are sequentially taken out for inspection and replacement.

  In an actual application, the bush 8 may be made of a metal material or a non-metal material. Alternatively, a metallic material and a non-metallic material may be combined in accordance with an external force actually received. Among them, bushes made from high-grade concrete are the most economical, have the longest life, have the right strength, and are the easiest to install. It can be reinforced by putting fiber or resin in concrete. Based on the principle of the present invention, the bush has a one-stage structure having the same size as the member to be floated, and the flange of the movable sleeve is a member to be directly floated. Locked to the bottom of the bush or locked to a groove installed in the bottom. A part of the movable sleeve may be left in the bush, or the whole may be left in the bush. In either case, the same effect can be realized.

  In addition, when the interior vibration isolator described in the first embodiment is applied to the floating slab having the above-described configuration of the present embodiment, in addition to installing the position limiting block 10, the movement in the axial direction in the preliminary through-hole is performed. The restriction block 40 that restricts the above should be installed at the same time. That is, mixed movement restriction is performed in the axial direction, radial direction, and circumferential direction of the through hole.

Example 4
As shown in FIGS. 13 and 14, the movable sleeve of the internal vibration isolator according to the present invention can be simplified to one support stopper 21. The elastic vibration isolator 3 is positioned below the support stopper 21, is installed by inserting an adjusting bolt 20 in the center of the support stopper 21, and has flanges extending outward along the four horizontal directions around the support stopper 21. 4 is provided. In this embodiment, the elastic vibration isolator 3 used is an air suspension vibration isolator.

When mounting, the vibration isolator of the present invention is inserted into the preliminary through hole, the support stopper 21 is rotated, the flange 4 is positioned below the shoulder and the stainless steel back plate 22, and is floated by the elastic vibration insulator 3. The flange 4 is locked to the stainless steel back plate 22 by adjusting the adjustment bolt 20 until the load from the slab 6 is received. When the number of elastic vibration insulators 3 that receive the load from the floating slab 6 is sufficient, the floating slab 6 is detached from the ground 12 to realize elastic floating. The adjustment bolt 20 is used again to complete the adjustment of the altitude and level of the floating slab 6, and finally, the floating roadbed including the interior vibration isolator of the present invention is configured.

  Further, in order to prevent the elastic vibration insulator 3 from sliding in the horizontal direction, an anti-slip plate 11 is further interposed between the elastic vibration insulator 3 and the ground 12. Further, a cover 13 is provided on the upper portion of the preliminary through hole in order to prevent foreign matter from falling into the preliminary through hole of the floating slab.

  In addition, since concrete has a life of more than 100 years and there are no members that adhere to the floating slab and easily corrode, even if the life of a movable sleeve made of carbon steel is less than 100 years, the movable sleeve rusts. Therefore, by replacing the damaged member, it is possible to satisfy the requirement that the total service life of the system reaches 100 years.

(Example 6)
As shown in FIG. 19, the floating road bed provided with the interior vibration isolator of the present invention is different from the first embodiment in the following points. That is, in order to simplify the lifting, four contact blocks 9 are installed on the inner wall of the preliminary through hole 7 of the floating slab 6 so as to be integrated with the floating slab. The contact block 9 is positioned above the support block 2 of the movable sleeve 1. Further, in order to adjust the number of washers 5 or the overall thickness smoothly from above, the size and shape of the central opening of the support block 2 and the contact block 9 are balanced with the washer 5, and the washer 5 is supported. It is possible to realize overlap due to positional deviation with the block 2 for use. Further, the size and shape of the central openings of the support block 2 and the contact block 9 are balanced with the elastic vibration insulator 3 in order to insert or remove the elastic vibration insulator 3 directly from above. Further, in order to prevent the elastic vibration insulator 3 from sliding horizontally, a slightly tapered protrusion 14 is formed on the bottom of the elastic vibration insulator 3 by overlay welding. After the elastic vibration isolator 3 receives a load, the protrusion 14 fits into the ground 12, and the horizontal sliding of the elastic vibration isolator 3 can be effectively prevented. In addition, since the process of lifting the floating slab and inspecting and repairing the movable sleeve and the elastic vibration isolator and the replacement process are similar to those of the third embodiment, the description thereof is omitted here.

  In the embodiment described above, the floating slab has been described as an example of all the members to be floated. However, based on the principle described above, the interior vibration isolator of the present invention can be applied to the floating roadbed as well as the floating slab. If it replaces the ground of the corresponding construction or the foundation of equipment, it can also be applied to vibration isolation of the foundation of construction and the foundation of equipment.
