Detailed description of the invention
Refer to shown in Fig. 1, Fig. 2, show the preferred embodiment of rubber vibration insulating pad of the present invention.
This vibration isolator at least includes surface layer 1 and multiple round platform projection 2, and this rubber vibration insulating pad, by under being arranged on concrete railway board and other load-carrying members, can carry out vibration isolation, noise reduction effectively.
Wherein, the plurality of round platform projection 2 is arranged at the side of surface layer 1 on the surface by array-like, each round platform projection 2 keeps at a certain distance away each other, in order to better form vibration isolating effect, this round platform projection 2 have employed special shape, and Fig. 3 is the structural representation of round platform projection 2 of the present invention, the key-like body of this round platform projection 2 symmetry that to be cross sections be made up of two semicircles 21 and two straight lines 22, the better effects if of pressure is born in the cross section that this key-like body is formed, and has damping and noise reduction preferably.
The size of round platform projection 2 can be selected completely as the case may be, preferred scope is: the semicircle radius R1 of protruding bottom surface is 0mm-100mm, be more preferably 30-60mm, straight length L1 is 0mm-100mm, be more preferably 30-60mm, the semicircle radius R2 of protruding end face is 0mm-100mm, be more preferably 10-60mm, straight length L2 is 0mm-100mm, be more preferably 30-60mm, the protruding 2 spaced distance A of round platform are 10mm-100mm, be more preferably 30-60mm, the height H of round platform projection is 10mm-100mm, be more preferably 30-60mm, other parameter is determined depending on concrete condition completely.
Wherein, the opposite side of this surface layer 1 is provided with covering layer 3 on the surface, in this covering layer 3, there is bonding jumper 4, this bonding jumper 4 can be utilized to connect the vibration isolator manufacturing more length and width degree and length: such as, be the bonding jumper between the vibration isolator of 1 meter by two width, the vibration isolator of 2 meters wide can be formed, thus, carry out lap connection by multiple vibration isolator, vibration insulation can be formed under whole tracks.
In order to better carry out vibration damping, be not limited to utilize a rubber vibration insulating pad to carry out vibration isolation, Fig. 4 demonstrates the situation that the superposition of two-layer vibration isolator uses, the covering layer 3 of two-layer rubber vibration insulating pad fits together, the round platform projection 2 of two-layer rubber vibration insulating pad extends toward the outer side, thus vibration isolation and damping is carried out to two-way vibration, for this reason, covering layer 3 is provided with tack coat.
Fig. 5 demonstrates four layers of vibration isolator superposition service condition, and between the two-layer rubber pad shown in Fig. 4, arrange a rigid slab 5, this rigid slab 5 does not play vibration isolating effect, but mainly plays a part to transmit and dispersion force.
Used by the bilayer shown in Fig. 4 or Fig. 5 or multiple-layer stacked, natural frequency can be made to be down to below 5Hz by rubber vibration insulating pad of the present invention, certainly, those skilled in the art are it is appreciated that can adopt the more multi-layered settings such as not shown five, six layers, eight layers.
Further, owing to having gap between round platform projection, water or other liquid can be smoothly through this vibration isolator, the drainage system of such as gutter and water pump can be utilized to be removed by liquid, and affect its performance under can not being deposited in vibration isolator.
When arranging, can according to different road conditions, different structures and different requirements, design size, round platform that is tapered with difference, different size at regular intervals protruding, preferred protruding by array-like arrangement.
Wherein, surface layer 1 can be made up of at least two-layer rubber layer, preferably, is being provided with fibrage between two between rubber layer, and thickness and the rigidity of each rubber layer are incomplete same, fibrolaminar thickness and rigidity incomplete same.
Fibrage can adopt woven cloth to make, and material is preferably EP200 or EE200, and not as limit.
Vibration isolator of the present invention can also be used for the basal layers such as bridge, tunnel, highway, stadium and interior of building, the vibration of structure and the secondary noise of structure can be alleviated, thus extend the application life of agent structure, reduce the security performance of maintenance cost and raising agent structure.The requirement of people to high-quality life can be met simultaneously, make it from the impact of high noisy, for the high-quality life requirement of people provides safeguard.By the difference of projection height physical dimension, vibration and the noise of vehicle operating generation can be reduced, improve the stability that railway roadbed is in operation.There are good ventilation, drainage between its space simultaneously, make the bottom of vibration isolator produce coagulation.
It is evident that, above description and record be only citing instead of in order to limit disclosure of the present invention, application or use.Although described in an embodiment and be described in the drawings embodiment, but the present invention do not limit by accompanying drawing example and describe in an embodiment as the optimal mode thought at present to implement the specific examples of instruction of the present invention, scope of the present invention will comprise any embodiment of manual and the appended claim fallen into above.
