Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification unless specifically stated can be equivalent or with similar purpose by other
Alternative features are replaced.That is, unless specifically stated, each feature is an example in a series of equivalent or similar characteristics
?.
For pot bearing and rubber pad and its pot bearing progress of accurately dynamometry are capable of specifically to the present invention below
It is bright.
An exemplary embodiment of the present invention, the raw material of the rubber pad for being used for pot bearing and capableing of accurate dynamometry
Including natural caoutchouc rubber or 90~110 parts of synthetic rubber, 4~7 parts of zinc oxide, 1~3 part of stearic acid, 10~30 parts of carbon black, sulphur
0~5 part, 2~5 parts of promotor, 2~5 parts of anti-aging agent, 10~50 parts of plasticizer and 0~10 part of processing aid.
Wherein, promotor can at least one of for DM, Cz, NA-22 and EM-35, anti-aging agent can for 4010NA,
At least one of RD, ODA and paraffin, plasticizer can be at least one of machine oil, DOP and paraffin oil, and processing aid can
Think at least one of CR-X, magnesia and HVA-2.Above-mentioned substance is commercial goods.
The production technology of the rubber pad can be prepared using the common processes of existing molded rubber product.It specifically, will be upper
State it is preforming after raw material is kneaded refill mould vulcanization, the rubber pad of size needed for being directly made or it is machining be required size

Fig. 1 shows structural schematic diagram (the compression sensor setting for capableing of the pot bearing of accurate dynamometry in the present invention
Outside rubber pad), Fig. 2 shows structural schematic diagram (the compression sensings for the pot bearing for capableing of accurate dynamometry in the present invention
Device is arranged inside rubber pad).
As depicted in figs. 1 and 2, the pot bearing for accurate dynamometry being capable of in the present invention includes bottom basin 1, middle steel plate 2, rubber
Pad 3 and compression sensor 4, rubber pad 3 are arranged between bottom basin 1 and middle steel plate 2, and compression sensor 4 is arranged in bottom basin 1
Bottom wall, side wall and/or middle steel plate 2 bottom or rubber pad inside, wherein the rubber pad 3 is above-mentioned rubber pad.
In assembly, first pass through above-mentioned special formulation and the pre-formed rubber pad 3 of technique in advance, then with bottom basin 1, intermediate steel
Plate 2 and compression sensor 4 assemble；Or be implanted into compression sensor 4 in rubber pad 3 in advance, then with basin bottom 1 and centre
Steel plate 2 completes the main structure assembly of pot bearing.Other attached and derivative structure such as upper sliding part, pressure-bearing pad sealings
(summary) is not indicated in the figures such as component.
The pot bearing is in stress, and when vertical load of the middle steel plate 2 by superstructure, pressure can be transmitted to pressure-bearing
Rubber pad 3 on, by rubber pad 3, pressure can be transferred on the bottom surface and side wall of bottom basin 1, and vertical force passes through the bottom of bottom basin 1 again
Portion is transferred to the pinner of bridge pier, completes vertical force transmitting.Rubber pad 3 plays buffering, damping effect wherein, and adapts to due to beam body
Rotation drives the rotation of middle steel plate, and corner is up to 0.025 radian.When pot bearing rotates, rubber pad 3 due to itself
Respectively to compression uniform properties, compression can be delivered evenly to pelvic cavity inner wall, the bottom and side wall including bottom basin, stress
Uniformly and bias-pressure phenomenon will not be generated.And it is mounted on any position or the compression being implanted in inside rubber pad sensing inside pelvic cavity
Device 4 obtain internal pressure be it is uniform, accurate, whether pipe support does not rotate.
Therefore, the present invention can be such that the load of pot bearing superstructure transmits more uniform reliable, and bridge beam body is turning
Stress raisers will not be generated when dynamic, the rubber pad of soft is respectively uniform to power transmission, so support dynamometry is more accurate.
The present invention is further explained in the light of specific embodiments.
