Abstract

The invention discloses a suspension type floating plate vibration isolation system, which comprises area floating plates, rubber vibration damping belts and a plurality of precast vibration isolation units, wherein the plurality of precast vibration isolation units are arranged on floor slabs or the ground, and are cast on site to form the area floating plates; the area floating plates are supported on the floor slabs or the ground by vibration isolators in the precast vibration isolation units and form gaps with the ground or floors to isolate vibration and noise; a plurality of area floating plates are arranged; and the rubber vibration damping belts are arranged among different area floating plates to limit the transmission of vibration in the horizontal direction. The suspension type floating plate vibration isolation system can isolate the vibration of machines from the floor slabs, is not needed to be jacked in the construction process and is easy to maintain and replace in the using process.

Description

technical field

[0001] The invention relates to the technical field of vibration and noise control, in particular to the vibration and noise control of power equipment vibration and rail transportation and the vibration control of an anti-micro-vibration chamber, and specifically refers to a suspended floating plate vibration isolation system. Background technique

[0002] Environmental vibration is recognized as one of the seven major public hazards. With the rapid development of modern industry and the continuous expansion of city scale, urban subway rail transit has increasingly become an important means to solve urban traffic. While the trend of urban subway construction is in the ascendant, vibration and noise problems caused by subway operation are gradually emerging. In recent years, my country's subway transportation system has developed rapidly. Since urban subways run through the city center, while undertaking the main traffic tasks of urban transportation, they a...

Examples

Embodiment 1

[0045] Such as Figure 1 to Figure 6 A suspended floating plate vibration isolation system is shown, the vibration isolation system includes a regional floating plate 102, a rubber vibration-absorbing belt 101 and a plurality of prefabricated vibration-isolation units 103, there are multiple regional floating plates 102, and the rubber damping belt Vibration belts 101 are arranged between floating slabs 102 in different areas to limit the horizontal transmission of vibration. Prefabricated vibration isolation units 103 and cast-in-place concrete slabs form regional floating slabs 102. Multiple prefabricated vibration isolation units 103 are placed on floors or On the ground, the regional floating slab 102 is supported on the floor or the ground through the vibration isolator of the prefabricated vibration isolation unit 103, forming a gap with the ground or the floor to isolate vibration and noise, that is, the regional floating slab 102 is suspended in the There is a vertical g...

Embodiment 2

[0055] Figure 7 to Figure 10 It is the second embodiment of the suspension floating plate vibration isolation system of the present invention, which is different from the first embodiment in that the floating floating plate in this embodiment is constructed by jacking.

[0056] The construction method of the second embodiment is to clean up the structural floor first, and keep the structural floor smooth, and level the uneven floor; before pouring concrete, lay PE film on the corresponding floor of the floating slab to avoid the concrete from colliding with the original The floor slab is stuck to the ground, so that the solidified concrete can be separated from the original ground smoothly when it is lifted; then the prefabricated vibration isolation unit 103 is placed on the floor according to the design, and the floating slab steel bars are bound, and the concrete is poured, and finally the The area floating floor 102 is lifted.

[0057] For the lifting method of the regio...

Embodiment 3

[0059] Figure 11 to Figure 13 It is the third embodiment of the suspended floating plate vibration isolation system of the present invention, which is different from the first embodiment in that the embedded part adopts the connecting sleeve 7 and the embedded plate 5 . The connecting sleeve 7 can also be pre-embedded in the concrete block 1 together with the embedded plate 5, and the embedded plate 5 and the connecting sleeve 7 are connected. Figure 12 As shown, the internal thread is processed at the corresponding position of the embedded plate 5. Of course, the embedded plate 5 and the connecting sleeve 7 in the embedded part can be connected by welding. The embedded board 5 is arranged horizontally and is located below the jacking function board 3 . The jacking function plate 3 adopts a circular plate with a square hole in the middle. The other structures of this embodiment are the same as those of the first embodiment.
