Abstract
The utility model relates to a plate type rubber supporting seat which can be used for measuring force, and comprises an A type and a B type; wherein, the A type rubber supporting seat is provided with a telescopic variable resistance which is added onto the original circular plate type rubber supporting base; the B type rubber supporting seat is provided with four telescopic variable resistances which are symmetrically added onto the diagonal of the original rectangular plate type rubber supporting seat; a spring is positioned on the lower part of the telescopic variable resistance; when the supporting seat bears force, the length of the spring can be shortened; and when the force is removed, the original length of the spring can be restored. Compared with the prior art, the utility model adopts the beam plate to measure the partial pressure difference of the telescopic variable resistance before and after the utility model is installed, so as to reflect the uniformity of the force born by each supporting seat and the contact between the beam plate and the support seat; the digital form changes the traditional method, which is used for detecting the contact between the beam plate and the supporting seat only through the visual measurement and can not be used for judging whether the force bearing is uniform; the utility model not only improves the efficiency of the work detection, but also effectively prevents the damage to various bridges and supporting seats, which is caused by the disengagement of the supporting seat and the uneven force bearing; and the service life of the simply supported girder bridge is prolonged.
Description
Technical field
The utility model provides a kind of novel laminated rubber bearing for simply supported girder bridge.
Background technology
At present, simply supported beam (plate) bridge generally adopts neoprene bearing, and neoprene bearing and beam slab installation are the important steps in the bridge construction.Beam, when plate is laid, must make that beam, plate are in place accurately and with bearing closely to be contacted, must not come to nothing, and should make each laminated rubber bearing all bear identical gravity as far as possible.After beam, plate were installed, the reply bearing checked that one by one this is one of the project that must examine in the bridge construction.
In the past, bridge construction and bridge inspection personnel can only check by simple tools such as telescopes, and must arrive the climbing stairs under bridge inspection, because pier is higher, headroom is very little between beam, plate and the pier cap, and inspection work is inconvenience very, and have certain danger.Whether the bridge pad installation quality checking tool of Ti Chuing can only contact with neoprene bearing from checking beam or plate in appearance in the past, and stressed whether evenly be unmeasured.
The utility model content
The purpose of this utility model is to overcome the prior art above shortcomings, for ease of checking the situation that contacts between beam slab and the neoprene bearing, but provides the laminated rubber bearing of a kind of novel laminated rubber bearing----dynamometry.Before beam slab is installed, quality control personnel are connected the measurement lead connection bearing of bearing with the bearing reaction measuring instrument, after beam slab is installed, can directly measure the end reaction that each bearing bears, the explanation bearing comes to nothing when end reaction is zero, when end reaction difference and difference surpass limit value, the reply height of support is adjusted, guarantee that each bearing can be evenly stressed, avoid coming to nothing or discontinuity causes beam slab hinge seam to destroy causing the stressed or bearing of monolithic beam slab to destroy, thereby effectively control simply supported girder bridge beam slab installation quality because of bearing.
Technical scheme that the utility model adopts is: this end reaction laminated rubber bearing of surveying comprises two kinds of A type and Type Bs.Wherein the characteristics of A type are to install a telescopic variable resistor additional at original circular laminated rubber bearing center, and a spring is housed under the described telescopic variable resistor, and length can shorten when bearing is stressed, cancel and can recover the original length when stressed.Three leads that described variable resistor is drawn are connected with the jack that is installed in circular laminated rubber bearing side, are defined as anodal jack, negative pole jack respectively and measure utmost point jack.The characteristics of Type B are evenly to arrange four telescopic variable resistors on the diagonal of the laminated rubber bearing of rectangle, a spring is housed under the described telescopic variable resistor, length can shorten when bearing is stressed, cancel and to recover the original length when stressed, three leads that described each variable resistor is drawn, wherein two leads of both positive and negative polarity are connected with the both positive and negative polarity jack that is installed in rectangular plate type neoprene bearing side respectively, measuring the utmost point then is connected with the measurement utmost point jack that is installed in rectangular plate type neoprene bearing side separately, be that each 1 of both positive and negative polarity jack is arranged on the rectangular plate type neoprene bearing, measuring utmost point jack then has four and corresponding with four variable resistors respectively.
In technique scheme, described variable-resistance both positive and negative polarity also can be directly to draw the neoprene bearing side with the form of lead with measuring the utmost point, directly is connected with the corresponding lead of end reaction measuring instrument when beam slab is installed.
Compared with prior art, the beneficial effects of the utility model are: the differential in partial pressures of utilizing burning voltage that telescopic variable-resistance both positive and negative polarity provides and beam slab that the fore-and-aft survey utmost point is installed is measured the power that each bearing bears and whether is reflected evenly that beam slab contacts situation with bearing, having changed the constructor with digitized form only depends on range estimation to observe beam slab to contact situation with bearing and can't judge stressed whether uniform method, both improved the speed of checking, also significantly reduced the probability of false judgment, thereby avoided coming to nothing because of bearing and the different types of rridges that discontinuity causes and the destruction of bearing in the past, effectively prolonged the application life of simply supported girder bridge.
