Description

A detachable vibration isolation device and a floating roadbed, a floor of a building, and the foundation thereof which employ the same.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the field of vibration and noise control, and more particularly relates to a vibration isolator that can reduce adverse effects of vibrations and noises occurring during the operation of tracked vehicles or vibrations of building members and facility foundations.

In the conventional track traffic structure, when the vehicle runs, large vibrations and noises are generated, which may affect surrounding buildings and facilities, and also cause harm to people. Therefore, in urban areas where populations and buildings are relatively concentrated, reduction of vibration and noise caused by orbital traffic is a particularly important problem. At present, by the intervening nodes of the respective damping measures, the damping measures are divided into three types: vibration blocking under track, vibration blocking under sleeper, and vibration blocking under roadbed. According to the vibration isolation principle and structural dynamics, the greater the vibration-involved mass of the vibration isolation system and the elasticity of the elastic element, the better the effect of vibration isolation. According to the structure of the track, the farther the intervening node of the vibration blocking measure is from the rail, the greater the elasticity and vibration engaging mass can be, the natural frequency and the range of vibration blocking can be reduced, and the effect of vibration blocking Improves. However, with respect to strength and mass, there are certain objective limits in other nodes, and they cannot be arbitrarily enlarged or reduced. For example, under the track, if the elasticity of the washer is arbitrarily increased, the rail deforms and its displacement is too large, which affects the safety of the driving. Therefore, when the request for vibration isolating is 10 decibels or more, the request cannot be satisfied unless the vibration isolating measures are taken under the road. A built-in vibration isolator is disclosed by Chinese patent ZL2004100354411, and the connecting sleeve of the vibration isolator is arranged in the floating plate, and the height of the connecting sleeve and the thickness of the floating plate are the same. Since it is necessary to lift, the jack support block and the support block are spaced apart from the inner wall of the connecting sleeve. Since the space for accommodating the floating tool is made between the jack support block and the support block, the height of the connecting sleeve is usually increased. However, in practical applications, due to limitations in space, cost, and environment, it is not possible to employ a floating plate because many connecting sleeves cannot be accommodated in a space made for a floating plate. On the other hand, in the process design, the height of the floating plate is usually determined late, the height and size of the connecting sleeve are respectively determined by the thickness of the floating plate, inventory production cannot be realized, and the time required for delivery becomes long. . In particular, when there is a design change during construction, since the cycle corresponding to the change is long, it is easy to influence the progress of construction.

The object of the present invention is to overcome the above problems, easily change the size of the mounting space for lifting, or do not need to prepare the mounting space for lifting in advance, can be delivered quickly by inventory production In addition, the present invention provides a partition type vibration isolator and its application which can be applied to a floating plate, a building floor, or a foundation of a facility having a different thickness within a larger height range.

Alternatively, the openings and the stop corners, which are sized and overlapped by the positional differences, are respectively arranged in the upper sleeve and the lower sleeve, and the stop corners pass through the openings, and then the contours of both can be superimposed on each other. The sleeve is rotated around the axial direction so as to realize the engaging connection between the upper sleeve and the lower sleeve.

The spring vibration circuit breaker is provided with a spring case and a spring installed in the spring case, and a coil spring, a disk spring, a rubber-metal composite spring, or a disk rubber-metal composite spring having elasticity at an appropriate strength in the longitudinal and transverse directions as a spring. It is possible to ensure the stability and vibration blocking effect in each direction of the floating plate even if the elastic support part or the limiting part which acts in the horizontal direction is not unnecessarily installed. A restraining damping material is provided on at least part of the surface of the spring, or at least part of the spring is fitted in the damping material. A sealing structure is disposed in the spring case, a liquid vibration damper is disposed in the spring case, and a lower portion of the spring is contained in the liquid vibration damper. The spring vibration breaker is arranged inside the connection sleeve and under the support block.

(2) In the case of mounting, when using the temporary auxiliary sleeve for only lifting the upper sleeve, the upper sleeve and the lower sleeve are first connected by the connecting structure.

(3) Put the spring vibration breaker and washer in the lower sleeve in order, and place the spring vibration breaker under the support block and arrange the upper surface of the washer slightly higher than the lower surface of the support block.

(4) Insert the hydraulic jack and jack support frame into the upper sleeve, insert the piston rod or its extension into the floating hole of the washer, support the jack support frame by the jack support block, drive the jack, and the washer Compress the spring vibration damper until it is slightly lower than the bottom of the support block.

(5) The washer is rotated to realize that the washer and the support block are overlapped by the positional difference.

(6) When the pressure of the jack is released, the spring vibration breaker exerts a force to press the washer against the support block of the lower sleeve, receives the load by the spring vibration breaker, and takes out the jack support frame and the jack.

(7) Repeatedly, the spring vibration breakers in all the lower sleeves of the floating member are subjected to loads sequentially until the floating member is separated from the base surface and finally reached a predetermined height.
