The utility model has the advantages that a bridge support and a force measuring system are integrated; the utility model has not only the normal work capacity of a bridge bearing, but also the functions of force measuring and supporting force adjusting in the construction of closure of bridge structure; the operating conditions of the supports can be coincident with the design; the comprehensive quality of bridge construction can be enhanced.
Description
The utility model relates to the pot rubber bearing that is applied to road bridge, railway bridge, overpass bridge structure and other structure support places, particularly discloses a kind of benzvalene form rubber Dynamometric support, belongs to the metal parts on road bridge, the railroad bridge.
At present, be applied to road bridge, railway bridge, the pot rubber bearing kind at overpass bridge structure and other structure support places has many kinds, its effect is in order to solve the bearing reaction at structure support place, rotate and displacement, thereby reach the purpose of actual use, common pot rubber bearing, a kind of longitudinally-moving pot rubber bearing is the two guide rails of linear pattern that adopt upper base plate and following seat board both sides to form, the installation accuracy height, run into the situation of curve in the installation process, two guide rails of bearing can produce stuck easily, bearing has only the bearing reaction effect, can not satisfy in the practical application and rotate and displacement, there is not sealing rubber ring in the structure in addition, dust and rainwater can enter in the pelvic cavity of bearing, influence the function and the application life of product, SH-PZ series pot rubber bearing can overcome the deficiency of two guide rail bearings, product is divided three classes: a class is unidirectional freely movable bearing, second class is multidirectional freely movable bearing, the 3rd class is a fixed bearing, unidirectional freely movable bearing is provided with a guide rail, being placed in upper base plate and middle steel liner plate claims again between the basin plug, be that a strip groove is arranged on the upper base plate, basin has a bar shaped boss beyond the Great Wall, cooperatively interact and be guide rail, the basin plug is a circular configuration, the basin plug can freely rotate in the basin ring, the basin ring also claims the steel tighten ring sometimes, therefore guide rail all the time can the keeping parallelism sliding mode, no matter how stuck phenomenon can not take place to bearing in mounting guide rail, bearing can satisfy actual behavior in service, the multidirectional freely movable bearing of second class, do not establish guide rail, have only a polytetrafluoroethylene (PTFE) slide plate and stainless steel slide plate between upper base plate and the basin plug, other component are identical with one-way support, on all directions, can both produce mobile between upper base plate and the basin plug, the 3rd class fixed bearing, upper base plate and basin plug combine as a whole, do not establish stainless steel slide plate and polytetrafluoroethylene (PTFE) slide plate between the two, the only supported counter-force of bearing, three class bearings all are provided with sealing rubber ring, can blocks dust and rainwater enter in the pelvic cavity.Two guide rail bearings that SH-PZ series compares, have many advantages, but, prestressed continuous beam waters the inspection practice or cantilever balance assembly unit method when adopting the cantilever balance in work progress, after the beam body closes up the system conversion, the actual counter-force of beam-ends fulcrum might not be coincide with the design counter-force, add that to close up back steel Shu Zhangla also variant with design in the stretch-draw time counter-force that beam-ends produces, so the mensuration of support reaction is to improve and check a fine method of construction comprehensive quality, existing bridge basin-type rubber support all can't be finished this task.
The purpose of this utility model is to disclose a kind of benzvalene form rubber Dynamometric support, and it can unite two into one dynamometric system and bridge pad, not only has the dynamometry function, but also can align support reaction, recovers the bearing operate as normal at last.
The purpose of this utility model is to realize like this, the pot bearing that is existing SH-PZ type is provided with an oil pocket with jack effect in the rubber bearing plate in its bearing, add an afterburner system and a dynamometric system, be exactly by upper base plate (1) specifically, corrosion resistant plate (3), polyfluortetraethylene plate (4), middle steel liner plate claims basin plug (5) again, rubber seal (6), rubber bearing plate (7), the steel tighten ring claims basin ring (8) again, the pot rubber bearing that following seat board (9) is formed, in the rubber bearing plate (7) that is characterised in that in pot bearing of the present utility model a special oil pocket (10) is set, how the flat jack of formula is the same with taking Lay two for the principle of this oil pocket, certain tonnage and the certain distance of jack-up of energy top lifting, the center of oil pocket is provided with a pump nozzle (14), the body of pump nozzle is positioned at seat board bottom center circular hole (15) down, pump nozzle is suitable for reading to be communicated with oil pocket (10), end opening is connected to pressure oil pump (12) by oil pipe (11), between pump nozzle and pressure oil pump, be connected in series an oil pressure gauge (13) in the oil pipe path, making block rubber play drum in the oil injection oil pocket, the basin plug jack-up of bearing, oil pressure gauge can record the oil pressure in the oil pocket, the oil pressure reading be multiply by the oil pocket area of plane, just it is fixed to record the weight that acts on bearing or Dynamometric support is placed on the enterprising rower of omnipotent machine, tonnage on the reading of oil pressure gauge and the omnipotent machine is set up one by one relation accordingly, just can learn then, how much weight how many oil pressure are exactly, be pressed in the beam body on the Dynamometric support, in oil pocket oil-filled add pressure handle beam body jack-up this in a flash, the reading of oil pressure, act on the weight on the bearing exactly, when this controls than difficulty in a flash, the very little distance of regulation of available jack-up is as standard, and oil pressure during this time is the weight that acts on the bearing.
The utility model is described in further detail below in conjunction with Figure of description.
Fig. 1 is unidirectional movable benzvalene form rubber Dynamometric support sectional view,
Fig. 2 is multidirectional movable benzvalene form rubber Dynamometric support sectional view,
Fig. 3 is a fixing pot type rubber Dynamometric support sectional view,
