Description
Technical field
The utility model relates to a kind of bridge bearing, especially relates to the unidirectional sliding support of a kind of bridge welding benzvalene form.
Background technology
The unidirectional sliding support of benzvalene form is the common components that bridge is connected with bridge pier, the operating principle of the unidirectional sliding support of benzvalene form is to utilize to be closed in the Intrapelvic elastic rubber slab of steel, the characteristics that under triaxial stress state, have the volume Incoercibility of fluid, the counter-force of bridge superstructure is delivered on the bridge pier reliably, and realizes the rotation of bridge beam-ends.The horizontal movement that relies on polyfluortetraethylene plate on the middle steel plate and the low-friction coefficient between the corrosion resistant plate on the bearing upper plate to realize superstructure simultaneously, the horizontal stress that bearing is born is no longer undertaken the whole thing by the pressure-bearing rubber tile, and indirectly-acting is in the slippage between basin at the bottom of the bearing and polyfluortetraethylene plate and the corrosion resistant plate, thereby guarantees the safe in utilization of bridge.So the unidirectional sliding support of benzvalene form can satisfy big bearing reaction, big horizontal movement, and big corner requirement.
Fig. 1 is the structural representation of the unidirectional sliding support of existing benzvalene form.The unidirectional sliding support of existing benzvalene form comprises upper plate, end basin, pressure-bearing rubber tile, polyfluortetraethylene plate, corrosion resistant plate and middle steel plate, the pressure-bearing rubber tile places in the end basin, and and seal by inner seal ring between the end basin, middle steel plate places on the pressure-bearing rubber tile, polyfluortetraethylene plate places in the groove on middle steel plate top, polyfluortetraethylene plate top is corrosion resistant plate, and topmost is a upper plate, is sealed by exterior seal ring between middle steel plate and the end basin.Connected mode between corrosion resistant plate and the upper plate is welding.
The material of unidirectional sliding support upper plate of existing benzvalene form and end basin, a kind of material is a cast steel, selecting cast steel for use is that its product detection means requires height as the weak point of material, need carry out ultrasound examination; The bad mechanical property of cast steel itself is compared with adopting other material under identical pressure-bearing grade in the mechanical performance and the application life of having reduced bearing integral body in addition, and the overall dimensions of bearing increases.Another kind of material is the low-carbon alloy steel (Q345) of high-quality, the good mechanical property of this material itself, but its processing technology is upper plate and the end basin that machining is made usually, and its weak point is that waste raw material, process-cycle are long, so the production cost of products height.
In addition, the inner seal ring material is a copper band in the prior art, and the friction between itself and the pressure-bearing rubber tile is bigger like this, makes pressure-bearing rubber tile serious wear, and the overall mechanical properties of the unidirectional sliding support of benzvalene form descends.
The utility model content
Technical problem to be solved in the utility model provides the unidirectional sliding support of the low bridge basin-type of a kind of cost of production;
Another technical problem to be solved in the utility model provides the good bridge basin-type of a kind of overall mechanical properties unidirectional sliding support.
For solving the problems of the technologies described above, the utility model provides a kind of bridge welding benzvalene form unidirectional sliding support, comprising:
Comprise upper plate, end basin, the pressure-bearing rubber tile, polyfluortetraethylene plate, corrosion resistant plate and middle steel plate, the pressure-bearing rubber tile places in the end basin, and and seal by inner seal ring between the end basin, middle steel plate places on the pressure-bearing rubber tile, polyfluortetraethylene plate places in the groove on middle steel plate top, polyfluortetraethylene plate top is corrosion resistant plate, topmost is a upper plate, seal by exterior seal ring between middle steel plate and the end basin, it between the inboard of the sidewall of upper plate and the middle steel plate complicated boundary slip material, it is characterized in that: the material of described upper plate and end basin is low-carbon alloy steel Q345, be welding between the tub wall of basin of the described end and basin are low, be welding between the top of described upper plate and the sidewall.
The technique effect that the utility model reached: the bridge unidirectional sliding support of welding benzvalene form of the present utility model is owing to adopt the low-carbon alloy steel Q345 of high-quality, and be welding between the tub wall of end basin and basin are low, be welding between the top of upper plate and the sidewall, when carrying out the product detection, only need butt welded seam to carry out ultrasound examination, do not need all steel plates are detected, saved labor cost, simultaneously because the welded construction of end basin and upper plate, less demanding to raw-material dimensions, it is simple to save material and processing technology, saved cost of production, overall mechanical properties improves simultaneously.
