Description
Technical field
The utility model is related to technical field of bridge, especially a kind of to adapt to the anti-of Short/Medium Span Bridge resistant slide
Slide sheet-type support.
Background technology
Common laminated rubber bearing is because the reason such as its comprehensive cost is cheap and construction method is cheap is in science of bridge building, especially
It is to be used widely in Short/Medium Span Bridge engineering.Two important indicators of common laminated rubber bearing type selecting are respectively bearing
Maximum vertical bearing capacity and minimum resistant slide bearing capacity, the middle-small span for being partially in high-intensity earthquake fortified defence area
Beam, or serviceability limit stage variable load effect account for the larger bridge of standard combination load effect, when bearing maximum vertical pressure-bearing
When power satisfaction is required, its minimum resistant slide bearing capacity or bearing horizontal distortion associated there can not generally meet bearing type selecting
It is required that, existing product typically all uses enhancing bearing and the adhesive property and enhancing bearing level of beam body to solve problems
To rigidity.
The problem of prior art is present is that also limit bearing while bearing anti-slipping property energy is strengthened normally uses rank
The reasonable deformation of section, easily produces Planar Mechanisms and bearing constructional difficulties to beam body.
Utility model content
A kind of resistant slide sheet-type support that the purpose of this utility model is in view of the shortcomings of the prior art and designed, using soft
Property presstressed reinforcing steel the upper and lower steel plate of bearing is connected to become entirety, and pass through the flexibility of ring steel plate and puller bolt formation self-balancing
Presstressed reinforcing steel anchoring system, forms anchor force, the anchorage style with the friction between bearing steel plate, pressing tight plate and flexible prestressing muscle
To flexible prestressing muscle not damaged, while avoiding the loss of prestress caused by fixture bounces back of traditional anchorage style, realization pair
The precompressed of laminated rubber bearing, should have high intensity, the low characteristic crept using flexible prestressing muscle, at the same its along bridge to anti-
Shearing rigidity should be much smaller than laminated rubber bearing, to meet beam body serviceability limit stage dilatation requirement, improve bearing and beam
The relative maximal friction slided is produced between body, it is ensured that anti-slipping property energy of the bearing under horizontal earthquake action, without to bearing
Horizontal displacement produce Planar Mechanisms influence, it is simple in construction, it is easy for installation, preferably resolve enhancing bearing anti-slipping property can
The problem of also limit the reasonable deformation of bearing serviceability limit stage simultaneously and easily produce Planar Mechanisms to beam body, greatly improves
The overall anti-slipping property energy of bearing, while also meet anti-slipping property energy of the bearing under horizontal earthquake action well.
What the purpose of this utility model was realized in：A kind of resistant slide sheet-type support, including by laminated rubber bearing with
Upper bracket steel plate and undersetting steel plate composition bearing, be characterized in upper bracket steel plate provided with pre-buried leveling steel plate, on hold out against
Plate and upper ring steel plate, undersetting steel plate are provided with lower pressing tight plate and lower ring steel plate, and the pre-buried leveling steel plate is set by upper dowel
On upper bracket steel plate, upper dowel is to be fixedly connected with upper bracket steel plate；The upper pressing tight plate is fixedly installed on by upper bolt
Bearing steel plate both sides；The upper ring steel plate is sleeved on outside upper bracket steel plate and is fixed on by upper puller bolt on upper pressing tight plate；Institute
State lower pressing tight plate and undersetting steel plate both sides are fixedly installed on by lower bolt；The undersetting steel plate is provided with lower dowel, lower dowel
It is to be fixedly connected with undersetting steel plate；The lower ring steel plate is sleeved on outside undersetting steel plate and is fixed on lower top by lower puller bolt
On tight plate；Flexible prestressing muscle is provided between the upper and lower bearing steel plate and upper and lower pressing tight plate, flexible prestressing muscle is by upper and lower
Bolt links into an integrated entity upper and lower bearing steel plate, realizes the resistant slide precompressed of laminated rubber bearing.
The laminated rubber bearing, pre-buried leveling steel plate, upper and lower bearing steel plate, upper and lower ring steel plate be rectangle or circle,
And upper and lower bearing steel plate and flexible prestressing muscle contact site are with sandblasting（Ball）Friction between processing increase and flexible prestressing muscle
Coefficient.
The upper and lower pressing tight plate is vertical bar plate or arc plate, and with flexible prestressing muscle contact site with sandblasting（Ball）Place
Coefficient of friction between reason increase and flexible prestressing muscle.
The flexible prestressing muscle is the high-strength steel sheet or carbon fiber composite sheet of bar shaped.
The upper and lower dowel is that one end sets threaded anchor pole, and it is anchored to by nut upper and lower bearing steel plate respectively
On.
The utility model has while improving and meeting resistant slide performance requirement compared with prior art, without limiting
The reasonable deformation of bearing serviceability limit stage and Planar Mechanisms influence is produced on beam body and bearing horizontal displacement, pass through upper and lower ring
The flexible prestressing muscle anchoring system of steel plate and puller bolt formation self-balancing, with bearing steel plate, pressing tight plate and flexible prestressing
Friction between muscle forms anchor force, the anchorage style to flexible prestressing muscle not damaged, while avoid traditional anchorage style because
Loss of prestress caused by fixture retraction, greatly improves the overall anti-slipping property energy of bearing, simple in construction, is easy to the installation of bearing
And change, manufacturing cost is low, is especially suitable for the popularization and application of Short/Medium Span Bridge resistant slide bearing.
