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 due to its comprehensive cost is cheap and construction method is cheap etc. 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 being partially in the middle-small span of 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 is met the requirements, minimum resistant slide bearing capacity or bearing horizontal distortion associated there can not usually meet bearing type selecting
It is required that existing product is to solve problems generally all using the adhesive property for enhancing bearing and beam body and enhance bearing level
To rigidity.
Problem of the existing technology is to also limit bearing normal use rank while bearing anti-slipping property energy is enhanced
The reasonable deformation of section easily generates Planar Mechanisms and bearing constructional difficulties to beam body.
Invention content
The purpose of the present invention is a kind of resistant slide sheet-type support for designing in view of the deficiencies of the prior art, using flexible pre-
The upper and lower steel plate of bearing is connected to become entirety by stress rib, and the flexibility for passing through ring steel plate and puller bolt formation self-balancing in advance should
Power muscle anchoring system, the friction between bearing steel plate, pressing tight plate and flexible prestressing muscle form anchor force, and the anchorage style is to soft
Property presstressed reinforcing steel it is not damaged, while avoid traditional anchorage style because fixture bounce back caused by loss of prestress, realize to board-like
The precompressed of rubber support should have high intensity, a 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
The maximal friction produced relative sliding ensures anti-slipping property energy of the bearing under horizontal earthquake action, without the water to bearing
Flat displacement, which generates Planar Mechanisms, to be influenced, simple in structure, easy for installation, is preferably resolved while bearing anti-slipping property energy is enhanced
It also limits the reasonable deformation of bearing serviceability limit stage and Planar Mechanisms easily is led to the problem of to beam body, substantially increase branch
The whole anti-slipping property energy of seat, while anti-slipping property energy of the bearing under horizontal earthquake action is also met well.
The object of the present invention is achieved like this:A kind of resistant slide sheet-type support, including by laminated rubber bearing and upper branch
Seat steel plate and undersetting steel plate composition bearing, its main feature is that upper bracket steel plate be equipped with pre-buried leveling steel plate, upper pressing tight plate and
Upper ring steel plate, undersetting steel plate are equipped 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 with upper bracket steel plate to be fixedly connected;The upper pressing tight plate is fixed at 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 fixed at undersetting steel plate both sides by lower bolt;The undersetting steel plate is equipped with lower dowel, and lower dowel is under
Bearing steel plate is is fixedly connected with;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 equipped 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, 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
Friction coefficient between reason increase and flexible prestressing muscle.
The flexible prestressing muscle is the high-strength steel sheet of bar shaped or carbon fiber composite sheet.
The upper and lower dowel sets threaded anchor pole, and it is anchored to upper and lower bearing steel plate respectively by nut for one end
On.
The present invention has while improving and meeting resistant slide performance requirement compared with prior art, without limiting bearing
The reasonable of serviceability limit stage deforms and generates Planar Mechanisms influence to beam body and bearing horizontal displacement, passes through 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 not damaged to flexible prestressing muscle, while avoids traditional anchorage style because of fixture
Loss of prestress caused by retraction greatly improves the anti-slipping property energy of bearing entirety, simple in structure, convenient for the installation and more of bearing
It changes, manufacture is at low cost, is especially suitable for the popularization and application of Short/Medium Span Bridge resistant slide bearing.
