Description
Technical field
The present invention relates to technical field of bridge, especially a kind of resistant slide for adapting to Short/Medium Span Bridge resistant slide
Sheet-type support.
Background technology
Common laminated rubber bearing as 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, for the middle-small span for being partially in high-intensity earthquake fortified defence area
Beam, or serviceability limit stage variable load effect accounts 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 cannot generally meet bearing type selecting
Require, existing product is to solve problems typically all to adopt the adhesive property and enhancing bearing level for strengthening bearing and beam body
To rigidity.
The problem that prior art is present is to also limit bearing normally to use rank while bearing anti-slipping property energy is strengthened
The reasonable deformation of section, easily produces Planar Mechanisms and bearing constructional difficulties to beam body.
The content of the invention
The purpose of the present invention is for the deficiencies in the prior art and a kind of resistant slide sheet-type support for designing, using flexible pre-
Bearing upper and lower steel plate is connected to become entirety by stress rib, and the flexibility for forming self-balancing by ring steel plate and puller bolt in advance should
Power muscle anchoring system, forms anchor force with the friction between bearing steel plate, pressing tight plate and flexible prestressing muscle, and the anchorage style is to soft
Property presstressed reinforcing steel not damaged, while avoiding traditional anchorage style because of the fixture loss of prestress that causes of retraction, realize to board-like
The precompressed of rubber support, 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 between bearing and beam body
Produce the relative maximal friction for sliding, it is ensured that anti-slipping property energy of the bearing under horizontal earthquake action, and the not water to bearing
Flat displacement produces Planar Mechanisms to be affected, and simple structure is easy for installation, preferably resolves while bearing anti-slipping property energy is strengthened
The reasonable deformation that also limit bearing serviceability limit stage and the problem that Planar Mechanisms are easily produced to beam body, substantially increase and prop up
The overall anti-slipping property energy of seat, while also meeting anti-slipping property energy of the bearing under horizontal earthquake action well.
The object of the present invention is achieved like this:A kind of resistant slide sheet-type support, including by laminated rubber bearing with upper
Seat steel plate and undersetting steel plate composition bearing, be characterized in upper bracket steel plate be provided with pre-buried leveling steel plate, upper pressing tight 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 arranged on by upper dowel
On bearing steel plate, upper dowel is to be fixedly connected with upper bracket steel plate;The upper pressing tight plate is fixedly installed on upper bracket by upper bolt
Steel plate both sides;The upper ring steel plate is sleeved on outside upper bracket steel plate and is fixed on upper pressing tight plate by upper puller bolt;Under described
Pressing tight plate is fixedly installed on undersetting steel plate both sides by lower bolt;The undersetting steel plate is provided with lower dowel, and lower dowel is with
Bearing steel plate is to be fixedly connected;The lower ring steel plate is sleeved on outside undersetting steel plate and is fixed on lower pressing tight plate by lower puller bolt
On;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
Upper and lower bearing steel plate is linked into an integrated entity, the resistant slide precompressed of laminated rubber bearing is realized.
The laminated rubber bearing, pre-buried leveling steel plate, upper and lower bearing steel plate, upper and lower ring steel plate are rectangle or circle,
And upper and lower bearing steel plate and flexible prestressing muscle contact site are with sandblasting(Ball)Process the friction between 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.
High-strength steel sheet or carbon fiber composite sheet of the flexible prestressing muscle for bar shaped.
The upper and lower dowel sets threaded anchor pole for one end, and which is anchored at upper and lower bearing steel plate respectively by nut
On.
The present invention is compared with prior art with while improving and meet resistant slide performance requirement, and does not limit bearing
The reasonable deformation of serviceability limit stage and Planar Mechanisms are produced on beam body and bearing horizontal displacement affect, by upper and lower ring steel plate
And puller bolt forms the flexible prestressing muscle anchoring system of self-balancing, between bearing steel plate, pressing tight plate and flexible prestressing muscle
Friction form anchor force, the anchorage style is to flexible prestressing muscle not damaged, while avoiding traditional anchorage style because of fixture
The loss of prestress that causes of retraction, greatly improves the overall anti-slipping property energy of bearing, simple structure, is easy to the installation and more of bearing
Change, low cost of manufacture, be especially suitable for the popularization and application of Short/Medium Span Bridge resistant slide bearing.
