The specific embodiment
Refer to shown in Fig. 1, Fig. 2, shown the preferred embodiment of rubber vibration insulating pad of the present invention.
This vibration isolator at least includes surface layer 1 and a plurality of round platform projection 2, and this rubber vibration insulating pad, by being arranged under 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 on a side surface of surface layer 1 by array-like, each round platform projection 2 keeps at a certain distance away each other, in order better to form vibration isolating effect, this round platform projection 2 has adopted special shape, the structural representation that Fig. 3 is round platform projection 2 of the present invention, the key shape body of this round platform projection 2 symmetry that to be cross sections be comprised of two semicircles 21 and two straight lines 22, the better effects if that pressure is born in the cross section that this key shape body forms, have vibration damping and noise reduction preferably.
The size of round platform projection 2 can be selected fully as the case may be, preferred scope is: the semicircle radius R 1 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 R 2 of projection end face is 0mm-100mm, be more preferably 10-60mm, straight length L2 is 0mm-100mm, be more preferably 30-60mm, the distance A of round platform projection 2 spaces is 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 looked concrete condition fully and is determined.
Wherein, be provided with covering layer 3 on the opposite side surface of this surface layer 1, there is bonding jumper 4 in this covering layer 3, can utilize this bonding jumper 4 to connect to manufacture the more vibration isolator of length and width degree and length: for example, bonding jumper between the vibration isolator that is 1 meter by two width, can form 2 meters wide vibration isolators, thus, carry out lap connection by a plurality of vibration isolators, can under whole tracks, form vibration insulation.
In order better to 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 two-layer vibration isolator stack is used, 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 is extended toward the outer side, thereby two-way vibration is carried out to vibration isolation and damping, for this reason, on covering layer 3, be provided with tack coat.
Fig. 5 demonstrates four layers of vibration isolator stack service condition, and a rigid slab 5 is set between the two-layer rubber pad shown in Fig. 4, and this rigid slab 5 does not play vibration isolating effect, but mainly plays a part to transmit and dispersion force.
By the bilayer shown in Fig. 4 or Fig. 5 or multiple-layer stacked, use, can natural frequency be down to below 5Hz by rubber vibration insulating pad of the present invention, certainly, those skilled in the art can know, can adopt the more multi-layered settings such as not shown five, six layers, eight layers.
And, due to gapped between the round platform projection, water or other liquid can be smoothly through this vibration isolator, can utilize such as the drainage system of gutter and water pump liquid is removed, and can not be deposited under vibration isolator, do not affect its performance.
When arranging, can be according to different road conditions, different structure and different requirements, design the round platform projection of size at regular intervals,, different size tapered with difference, preferred projection is arranged by array-like.
Wherein, surface layer 1 can be comprised of at least two-layer rubber layer, preferably, is provided with fibrage between rubber layer in twos, and thickness and the rigidity of each rubber layer are incomplete same, and fibrolaminar thickness and rigidity are incomplete same.
