Abstract

The invention discloses a force-monitoring support structure, comprising a steel basin, a rubber plate, a sealing ring, an elastomer pressure transmitter, a pressure gauge and other components included in a support. The rubber plate is arranged in the cavity of the steel basin, 2-4 internal threaded holes are formed in the periphery of the steel basin, and one section of the elastomer pressure transmitter is provided with outer threads, which form threaded connection with the internal threaded holes formed in the periphery of the steel basin. A force-monitoring terminal of the elastomer pressure transmitter is in touch with the rubber plate. A signal line of the elastomer pressure transmitter is connected with the pressure gauge. The force-monitoring support structure is simple and reliable in structure, wide in force-monitoring range, small in error, convenient to install, disassemble and replace, and longer in service life.

Description

A kind of Dynamometric support structure
Technical field
The present invention relates to bridge technology field, be specifically a kind of brand-new Dynamometric support structure.
Background technology
China is vast in territory, complicated geological configuration.And some bridges must be built in these complicated geological structures.The geology of these complexity is probably hard rock, it is also possible to soft gravel or drift sand.Although soft gravel or drift sand basis can carry out the consolidation process of necessity, but not put things right once and for all.Actually used middle settlement of foundation and displacement, cause bridge pier to deflect, and causes bridge normally to use and even caves in.
It addition, for stayed-cable bridge or suspension bridge, counter-force and the change of monitoring main bridge seat can be to control the lax of long suspension cable and beam body stressing conditions near direct measuring to bearing, the formulation for bridge drag-line, the maintenance of girder and maintenance measure provides auxiliary foundation.
The most domestic Dynamometric support applied to mainly has two kinds of structures, and one is liquid glue bellows, and another kind is pressure ring type.Liquid glue bellows utilizes hydraulic principle, by arranging liquid capsule at Impact direction, is full of liquid in capsule, by compression capsule, measures CF body pressure and counter push away bearing vertical applied force.Pressure rings is a strain gauge element, and under vertical load, pressure rings produces circumferential deformation, and the strain gauge element resistance being pasted onto ring periphery changes, this change by data collecting module collected, analyze, process after, complete the vertical force measuring function of bearing.
Liquid glue bellows Dynamometric support.Using liquid or resinous material is dynamometry medium, seals difficulty, and difficulty of processing is big, and life-time service can occur dielectric leakage to obtain possibility.Once medium is revealed, and dynamometry precision i.e. reduces and cannot recover.
Pressure ring type Dynamometric support.Its signals collecting uses traditional patch foil gauge mode.For being placed in the foil gauge of wild environment for a long time, affected greatly by extraneous factor, even and if in preferable environment use, its service life is the most relatively low, it is impossible to meet bridge use requirement.For pressure rings itself, equally exist service life low and cannot realize in the case of not jacking bridge change.
Summary of the invention
In view of the above deficiency of prior art, a kind of dynamometry scope is big, cost is relatively low, precision is high, the Dynamometric support structure of length in service life to it is an object of the invention to offer at this.
The object of the present invention is achieved like this: a kind of Dynamometric support structure, includes other component that steel basin, rubber slab, sealing ring, elastomer pressure transmitter, pressure meter device and bearing should have;Rubber slab is arranged in the pelvic cavity of steel basin, and steel basin periphery uniformly opens 2~4 internal thread holes, and one section of elastomer pressure transmitter is formed threaded for external screw thread the internal thread hole offered with steel basin periphery.The dynamometry termination of elastomer pressure transmitter contacts with rubber slab.The holding wire of elastomer pressure transmitter is connected with Pressure gauge.
The special rubber slab material and the sulfuration process that there is provided for the present invention all need specialized designs for dynamometry, and meet the requirement to rubber slab of the bearing standard.Bound rubber degradation and pressure test, simulation various sizes specification, pressure and the data of each ageing step, final employing database generalization programming, form output result.
The beneficial effects of the present invention is the following aspects:
Economy: for original design as pot rubber bearing class, in addition to the elastomer pressure transmitter set up, other only needs its original General Purpose Rubber plate is replaced by special rubber slab, and special rubber slab overall dimensions can be consistent with General Purpose Rubber board size;For original design as spherical steel support class, though the structure of end basin and rubber slab need to be set up, but bigger change will not be caused by bearing, economically be better than other type of dynamometry structure;
Convenience: liquid glue bellows dynamometry due to needs close-ups Pressure gauge indicating value, therefore needs in a lot of projects to observe on the bridge pier that several meters of rice the most tens of are high, it has not been convenient to use.And the present invention can by dynamometry signal by wire transmission to safety area even with in transmission of wireless signals to receptor (such as mobile phone), can real time inspection Bearing Seat Force situation and change thereof.
Service life: dynamometric system service life of other type of Dynamometric support, in the life-span same with bearing such as the steel basin of the dynamometric system of the present invention, rubber slab, sealing ring, elastomer pressure transmitter service life was up to 10 years less than 5 years.
Safety: the device for measuring force of this Dynamometric support is as the device for measuring force of current other type of Dynamometric support, although service life is of a relatively high, but the most all it is unable to reach the life-span same with bearing, reach to need during design service life to change dynamometric system.Other type of Dynamometric support is changed dynamometric system and is required to jacking bridge, and the present invention need not jacking.Being both designed as the life-span same with bearing due to steel basin, rubber slab, sealing ring etc., staff only needs to carry the simple tools such as spanner can realize the replacing of pressure transmitter, and safety is greatly promoted compared to other type.
