In order to reduce the interference to the upper or surrounding property and residents, the installation of floating slab bed in special sections is an important vibration isolation measure in subway design. The currently applied floating track bed vibration is mainly divided into built-in and side-mounted according to the installation method. The conventional built-in vibration isolating device needs to pre-fix the connecting movable sleeve in the floating plate. For example, the invention patent of the patent number ZL20041 0035441. 1 discloses such a floating track bed, which is connected to the movable sleeve during operation. The fixedly arranged support stop is supported as a direct force-receiving element on the spring isolator. At present, the industry standard requires that the design life of the floating plate is at least 100 years. For such a long time, the movable sleeve made of ordinary carbon steel material (such as Q2 35 or Q 345) is corroded and alternating. Stress, the main stressed parts are prone to fatigue damage, open welding and rust and thinning, but because the connecting movable sleeve has been integrated with the floating plate, it cannot be directly replaced, and the local maintenance is subject to It is very difficult to limit the location and the space inside the movable sleeve. When repairing, it takes a long time to interrupt the operation of the vehicle, which will inevitably bring inconvenience to the citizens, bring economic losses to the operating company, and adversely affect the daily activities of the city. Moreover, the vibration isolator of this structure is used, no matter how thick the floating plate is, the overall thickness of the connecting movable sleeve needs to be consistent with the thickness of the floating plate, and more materials are consumed. At the same time, in order to repair and replace the spring isolator at any time, the traditional built-in vibration isolation device adopts the technical solution that the spring isolator can be directly taken out through the through hole on the coupling sleeve, which requires that the through hole size must be slightly larger than The size of the spring isolator is such that the size of the coupling sleeve is correspondingly large, which takes up more space and is not conducive to cost reduction. Summary of the invention It is an object of the present invention to overcome the above-mentioned deficiencies, to provide a movable sleeve that can be removed for inspection and replaceable, and the height of the movable sleeve and its through-hole size are no longer affected by the thickness of the floating plate and the elastic isolators.

Therefore, the elastic vibration isolator can be taken out without passing through the central opening of the support stopper or/and the jacking stopper, and the movable sleeve is first taken out, and then the elastic vibration isolator is taken out. Just fine. Of course, if the project needs to load or remove the elastic isolator directly from above, only the central opening and shape of the support block or / and the jacking block are compatible with the size of the elastic isolator, without using the spacer At the same time, it should also be ensured that the upper top surface of the elastic vibration isolator can at least overlap with the support stop.

The flange of the movable sleeve of the built-in vibration isolating device is symmetrically arranged, including axisymmetric or central symmetry. In order to protect the reserved through-hole structure of the floating plate and the movable sleeve from being damaged, a liner can be added in the reserved through hole. In order to guarantee the 100-year service life required by the standard, the liner should be made of corrosion-resistant and durable materials. The liner can be made of metal materials, such as stainless steel, aluminum alloy and carbon steel with good corrosion protection; it can also be made of non-metallic materials with sufficient strength and durability, such as engineering plastics, ceramics, hard rubber. , FRP, concrete prefabricated parts, etc.; can also be combined or composited from metal and non-metal materials according to the actual external force, for example, the ceramic protective steel plate is used in the shoulder part of the vibration isolation device. A portion of the side wall of the through hole is made of a rubber material containing a steel skeleton, and the steel sheet and the rubber are vulcanized and integrated to form a liner.

Embodiment 1

As shown in FIG. 1 and FIG. 1 , the built-in vibration isolating device of the present invention comprises a movable sleeve 1 and an elastic vibration isolator 3 . In the present embodiment, the elastic vibration isolator 3 is a spiral steel spring partition with a liquid damping material disposed therein. The vibrator, the movable sleeve 1 is provided with a support block 2, the elastic isolator 3 is located below the support block 2, and the lower part of the movable sleeve 1 is horizontally provided with four outwardly projecting flanges 4. In order to facilitate the adjustment of the height and the level of the vibration isolating member from above, a spacer 5 is arranged between the support block 2 and the elastic isolator 3, and the top 5 of the spacer 5 is provided with a jacking through hole, and the size of the spacer 5 is ensured. The through hole is passed through the center of the support block (ie, the size is compatible), and after the rotation, the misalignment overlap can be realized with the support block 1, and the state when the two are misaligned is as shown in FIG. 2.

When used in the track floating plate, as shown in FIG. 3 and FIG. 4, a reserved through hole 7 corresponding to the shape of the vibration isolating device is preset on the floating plate 6, and the reserved through hole 7 has a small cross section of the upper portion. A stepped hole having a large cross section in the lower section is further provided with an axial stopper 40 on the through hole. The elastic isolator 3 and the movable sleeve 1 are placed in order, and the spacer 5 is placed at the center hole of the support stopper 2. Compressing the spring isolator 2 with an external pressure tool until the flange 4 is lower than the shoulder A of the reserved through hole 7, at which time the axial stop block 40 holds the movable sleeve upward, as shown in FIGS. 5 and 6. Continue to compress the isolator so that the shim 5 is completely below the support stop 2 and the movable sleeve 1 is rotated about 45. , the gap between the gasket 5 and the support block 1 and the flange 4 of the movable sleeve 1 and the shoulder A form a misalignment. When the external pressure device stops applying pressure, the elastic vibration isolator 3 will rebound. , the gasket 5 and the support block 1 and the flange 4 and the shoulder A are pressed against each other, so that the floating plate 6 is elastically supported on the elastic vibration isolator 3, when the spring isolator is loaded enough, the floating plate 6 will be detached from the surface of the foundation 12 to achieve floating, and constitute a floating track bed with built-in vibration isolating device of the present invention.

When a spacer 5 cannot satisfy the adjustment of the floating panel 6 to an appropriate height or level, the newly added spacer can be placed at the center through hole of the support stopper 2 according to the foregoing method, and then utilized. The pressure tool directly presses the spring isolator through the jacking through hole provided in the center of the gasket until the newly placed gasket is completely lower than the support stopper. At this time, the newly placed gasket is rotated by about 45° to make a new one. The gasket is also formed to overlap with the support block, and the pressure is applied to stop the spring isolator and the gasket is pressed against the support block, so that the total thickness of the gasket is adjusted until the final realization. The floating plate reaches the appropriate height and level. Of course, in some cases, the spring isolator can be directly supported on the support block without a spacer.

When overhauling or replacing the movable sleeve and the elastic isolator, first compress the elastic isolator 3 with an external jack to disengage the flange 4 from the shoulder A and rotate the movable sleeve 1 45. , the flange 4 and the shoulder A are no longer misaligned, the upper through hole and the movable sleeve 1 enter a compatible state, the external jack is released, and after the elastic vibration isolator 3 rebounds, the components are no longer subjected to force, The movable sleeve 1, the spacer 5 and the elastic vibration isolator 3 are easily taken out from the reserved through holes for inspection or replacement.

In order to prevent the horizontal vibration of the elastic vibration isolator 3, an anti-slip mat 11 having a high friction coefficient is disposed between the elastic vibration isolator 3 and the foundation 12. In order to prevent foreign matter from falling into the through hole of the floating plate, an end cover 13 is provided at the top of the reserved through hole. In order to enhance the sealing effect and better prevent rain and dirt from entering, it is also possible to provide a gasket around the end cover. The end cap can also be placed in an embedded manner so that its upper surface is flush with the surface of the floating plate and is also easy to implement.

This embodiment is described only in the case where four flanges 4 are provided. In practical applications, the number of flanges may be increased or decreased according to the space and load requirements, but generally at least two are required to ensure the stability of the support. , not less than three is appropriate.

According to the spirit of the present invention, the shape of the through hole at the center of the movable sleeve may be a shape of a triangle, a trapezoid, an ellipse, a rectangle or the like in addition to the shape described in the embodiment, as long as the shape of the spacer is changed correspondingly. The same effect. Moreover, the structural form of the gasket according to the present invention is not limited to a solid plate. For a case where the thickness of the floating plate is large, the gasket may be provided as a hollow casing and a barrel structure with flanges at both ends. Various forms, as long as the strength is sufficient, can achieve the same effect.

In addition, the reserved through holes provided on the floating plate may be triangular holes, square holes, rectangular holes, polygonal prism holes, elliptical holes, or belts, in addition to the circular holes with symmetric notches shown in this example. Other shapes with symmetrical notches can achieve the same effect as long as the movable sleeve, the backing plate and the elastic vibration isolator can be adapted accordingly.

The elastic vibration isolator used in the built-in vibration isolating device of the present invention includes various forms, except this example. In addition to the steel spring isolator, it may also be a rubber isolator or an air spring isolator. The elastic element used for the crucible may be a spiral steel spring, a disc spring or a rubber metal composite spring, or a rubber. For other elastic materials, other liquid damping materials such as modified asphalt or solid damping materials such as rubber may be simultaneously disposed in the elastic vibration isolator.

Since the life of concrete can be more than 100 years, there are no corrodible parts that are not consolidated together on the floating plate. Although the life of the movable sleeve made of carbon steel is less than 100 years, if the corrosion can be replaced, it can be replaced in time. Meet the life expectancy of the entire system for up to 100 years.

Based on the principle described in this example, the built-in vibration isolating device of the present invention can be used not only for vibration isolation of floating track beds, but also for vibration isolation in the fields of building floors and equipment foundations.

Embodiment 2

As shown in FIG. 7 and FIG. 20, the floating track bed with the built-in vibration isolating device of the present invention is different from the first embodiment in that it is difficult to realize the stepped reservation when the thickness of the floating plate 6 to be isolated is thin. When the through hole provides the required shoulder for hooking, a single-sized reserved through hole 7 can be disposed on the floating plate 6, and then the flange 4 is directly attached to the bottom surface of the reserved through hole of the floating plate 6. The support of the elastic vibration isolator 3 to the floating plate 6 can also be realized. It should be noted that the elastic vibration isolator 3 in this example is a spiral steel spring damper with a rubber solid damping material inside. In order to smoothly realize the attachment of the flange 4 and the bottom surface of the floating plate 6, a concrete pier 19 may be preliminarily provided on the base surface 12, and the floating plate 6 is supported by the concrete pier 19 so that the floating plate 6 is separated from the surface of the base 12 by a distance. In order to ensure that there is enough space for hooking.

Of course, the height of the concrete pier 19 needs to be determined by calculation, and it is necessary to ensure that the hanging space of the flange 4 and the bottom surface of the floating plate 6 is reserved, and the concrete pier 19 is not ensured when the floating plate 6 is in a floating state. Contact interference occurs with the floating plate 6. Based on this principle, it is also possible to provide a plurality of projections similar to the concrete pier 19 on the floating plate when the floating plate 6 is cast, and the same effect can be obtained.

As in the first embodiment, the life of the movable sleeve made of carbon steel in this example is less than 100 years, but if the rust can be removed from the through hole and replaced, it can be replaced by the system in time for up to 100 years. Service life requirements.

Embodiment 3

As shown in FIG. 8, the difference from the first embodiment is that the built-in vibration isolating device is used to adjust the height and level of the floating plate 6 from above, and the top of the movable sleeve 1 is provided. Upstop block 9, the center opening and shape of the jacking block 9 should also be compatible with the size of the spacer 5, which are all complex opening shapes composed of triangles and circles, which are 120° center symmetrical, and the jacking block 9 is located. Above the support block 2.

When applied to the floating track bed with the built-in vibration isolation device of the present invention, in order to avoid the inconvenience of providing a special shape of the reserved through hole on the floating plate, and protecting the reserved connection with the movable sleeve on the vibration isolating member The hole structure is not damaged, and a liner 8 is added in the reserved through hole. Wherein, the reserved through hole is set as two square stepped holes with a large cross section of the upper section and the lower section of the upper section, and the corresponding liner 8 is also provided in the same shape, and the liner 8 is made of the steel plate which has been treated with anti-corrosion treatment, because the shoulder B is When working, it is connected to the flange 4 to receive force, so a thicker steel plate is locally used at the shoulder B. In order to ensure that the relative position of the flange 4 and the shoulder B are not changed, a card slot formed by the limiting block 10 is disposed at a corresponding position of the shoulder B. In order to prevent the horizontal movement of the elastic vibration isolator 3, a plurality of tapered projections 14 are welded to the bottom of the elastic vibration isolator 3, and an anti-slip pad 1 1 is disposed between the gasket 5 and the elastic vibration isolator 3.

The specific application manner is as follows: as shown in FIG. 8 and FIG. 9, the liner 8 and the floating plate 6 are pre-cast into one body, and then the elastic vibration isolator 3 and the movable sleeve 1 are sequentially placed in the liner 8 and The spacer 5 is placed at the center hole of the support block 1, and when the movable sleeve 1 is placed, in order to give way to the flange 4, the flange 4 should correspond to the diagonal direction of the opening of the liner as shown in FIG. Put in, rotate the movable sleeve 1 through about 45°, and overlap the shoulder. When the jacking is installed, as shown in FIG. 10, the jacking bracket 16 is used to cooperate with the jacking block 9 to provide a supporting point, and the hydraulic jack 15 is driven to press, compressing the elastic vibration isolator 3 until the spacer 5 is lower than the supporting The block 2 rotates the washer 60°, overlaps the support block 2, and then the jack 15 is unloaded, the jacking bracket 16 and the hydraulic jack 15 are removed, and the spring isolator rebounds, so that the washer 5 and the support The stopper 1 and the flange 4 and the shoulder B are pressed against each other. At this time, the spacer 5 is misaligned with the support stopper 2, and the flange 4 is embedded in the card slot formed by the stopper 10, as shown in Fig. 11. In this way, the floating plate 6 is elastically supported on the elastic vibration isolator 3. When the spring isolator participating in the bearing is sufficiently large, the floating plate 6 will be separated from the surface of the foundation 12 to realize floating, and the invention has a built-in partition. The floating track bed of the vibrating device is shown in Figure 12. In order to better prevent rain and debris from entering, an end cap 13 and a gasket 17 are provided on the reserved through hole. The size of the card slot formed by the control limit block 1 0 can not only achieve the limit of the movable sleeve in the reserved through-hole direction, but also realize the limitation of the radial direction of the reserved through hole.

When the movable sleeve and the elastic vibration isolator are repaired or replaced, the elastic vibration isolator 3 is first compressed by the jack 15 and the jacking bracket 16 to disengage the spacer 5 from the support stopper 2, and the spacer 5 is rotated 60. , The spacer 5 and the support block 1 are no longer misaligned, but enter a compatible state, and the jack 15 is released. After the elastic vibration isolator rebounds, the components are no longer subjected to force, and the movable sleeve can be easily removed. The gasket 5 and the vibration isolator 3 are sequentially taken out for inspection or replacement.

In the actual application process, the liner 8 can be made of a metal material or a non-metal material, and can be composed of a combination of a metal and a non-metal material depending on the actual external force. Among them, the liners made of high-grade concrete are most economical, have the longest life, moderate strength, and are most convenient for construction. Fiber or resin is added to the concrete soil for reinforcement. Based on the principle of the present invention, for a member to be floated having a small thickness, the liner can even be set to a section of the same size, and the flange of the movable sleeve is directly attached to the bottom of the member to be floated or the liner, or the bottom thereof is disposed. In the IHJ slot. The movable sleeve can be partially placed in the liner or all of it can be placed in the liner to achieve the same effect.

It should be noted that, if the built-in vibration isolating device described in the first embodiment is applied to the floating plate of the structure described in this embodiment, in addition to the setting of the limiting block 10, it should be simultaneously set in the reserved through hole. The axial limiting block 40, that is, the combined limiting in the axial, radial and circumferential directions of the through hole.
