Description
Technical field
The present invention relates to bridge expanssion joint sealing techniques, especially " array bridge expanssion joint ", mainly bridge without
Isometry block is referred in the flexible sealing technique of seam.
Background technique
Bridge expanssion joint is a generally acknowledged technical problem of world's highway circle, and expansion joint influences the flatness of highway
It is larger, also directly affect the level of comfort of driving.Chinese Patent Application No.: 201610037260.5, " bridge expanssion joint dress
Set ", the side of left fishback backbar towards right fishback backbar is fixed with the left embedding seat of waterstop, right fishback backbar court
The side of fishback backbar and it is fixed with the right embedding seat of waterstop in the position for corresponding to the left embedding seat of waterstop to the left, waterstop is embedding
It sets between the left embedding seat of waterstop and the right embedding seat of waterstop.Such expansion joint is in use, since dust is very easy to
It accumulates at the activity at expansion joint, is then fallen into waterstop from the gap at expansion joint, and clearing up waterstop is that part is cumbersome
Thing.Chinese Patent Application No.: 201310592138.0, " a kind of bridge composite seamless expansion joint ", including by be capable of fixing in
Constitute being superimposed the compound structure that is pressed into of vulcanization between the two neighboring prefabricated component gap of bridge by several layers steel plate and rubber layer
Part and the pitch lastics being made of rubble and asphalt material for being set to the composite component Yu its two sides deck paving interlayer
；Be set to the width of the left and right pitch lastics of the deck paving interlayer of the composite component and two sides, wherein wagon flow to first
Left pitch lastics width be greater than wagon flow backward right pitch lastics width.This gapless expansion joint can remove from only
The cleaning work of water band, it is theoretically very good, but from the structure of this patent application for, the amount of tension of steel plate itself is
It is very small, and the superposition of multilayer steel plates in this form, the stroke of stretching are just smaller, expansion joint in this form
Stroke very little.In addition, the pulling force that expansion joint is received is bigger, rubber layer is thinner, the height in addition weight of wheel, at composite component
The height that will be lower than road surface influences the stationarity of driving.Rubber layer carries on a shoulder pole telescopic action when stretched herein, also acts as
Pressure-bearing effect, so that the performance of rubber layer is difficult to take into account two kinds of functions.
Summary of the invention
In order to improve the series of bridge expanssion joint, the present invention tries hard to provide a kind of array bridge expanssion joint, it is by bridge
The weight-bearing function at gapless expansion joint distributes to isometry block, and the function distribution of dilatation and sealing is to filling block.
The technical solution adopted by the present invention to solve the technical problems is: array bridge expanssion joint, the bridge of filler production
In beam expansion joint, filling block is one piece of overall structure, and wherein array is disposed with isometry block, line number >=1, columns >=3.Isometry block
Shape can be circle, it is rectangular, triangle or other shapes.The length-width ratio of the containment area of isometry block is less than 5:1, packet
The length-width ratio for holding area is best when being 1:1, and at this moment isometry block is equal and minimum with lateral confinement power to the longitudinal restraint power of filler,
So cylindrical isometry block restraining force is minimum.The array plane of isometry block is parallel with road surface, and top surface is contour with road surface, side
Rough surface, or have boss or have shrinkage pool or have zigzag or be evenly equipped with wing plate.On the filling block one end at expansion joint and bridge
Road surface connection, the other end are connect with another road surface on bridge.The filler highly elastic material at expansion joint, such as rubber, height
The special pitch of elasticity.One layer of steel plate of one layer of hard material or pad can be spread in the bottom of isometry block.Be conducive to slide, be conducive to bridge
The protection in beam face.
The method of array bridge expanssion joint is, by the smooth function distribution of the load-bearing at bridge gapless expansion joint and road surface
To isometry block, the function distribution of dilatation and sealing is to filling block, and array is disposed with isometry block in filling block, expansion joint
Its top of isometry block is contour with road surface, the bearing block of the receiving wheel weight with rigid material production of isometry block, the packet of isometry block
The length-width ratio for holding area is less than 5:1, is connected to filler, filling block of the filler combination at an entirety, filler around isometry block
The use plasticity or elastic material of block make, and play the viscous connection function filled out between expansion joint and bearing block.
The invention has the advantages that by the smooth function distribution of the load-bearing at bridge gapless expansion joint and road surface to contour
The function distribution of block, dilatation and sealing is to filling block, and array is disposed with isometry block, the isometry block at expansion joint in filling block
Its top is contour with road surface, and the bearing block of the receiving wheel weight with rigid material production of isometry block both can guarantee expansion joint
Load-bearing capacity can guarantee the ride comfort on road surface again.Be connected to filler around isometry block, filler combination at an entirety filler
Block, use plasticity or the elastic material production of filling block, plays the viscous connection function filled out between expansion joint and bearing block.Filler is no longer
Take on the effect of pressure-bearing, the selection of filler formulation is much older, and filler need to only undertake deformation and the sealing at expansion joint.Isometry block can mention
The ride comfort at high similar expansion joint, filler, which no longer takes on pressure-bearing, can increase the stroke at expansion joint.
Detailed description of the invention
The array arrangement schematic diagram of Fig. 1 isometry block.
Fig. 2 isometry block is by filling packing schematic diagram.
The scheme of installation of Fig. 3 array bridge expanssion joint.
In fig. 1 and 2,1. isometry blocks, 1.1. wing plate, 1.2. filling hole, 2. connection straps, 2.1. bury muscle, 2.2. installation
Hole, 3. filling blocks, 4. strip of paper used for sealings, 5. bridge plates, 6. waterstops.
Specific embodiment
In Fig. 1, Fig. 2 and Fig. 3, the highly elastic material of filling block 3 at expansion joint, such as rubber, elastomeric special drip
Blueness, in the bridge expanssion joint that filling block 3 makes, wherein array is disposed with isometry block 1, and line number is equal to 3 in figure, due to being three
Angular array, the columns of middle row are equal to 8, and the columns of two row of side is equal to 9.The top surface of isometry block 1 and road surface are contour, make
With the weight for being subject to wheel, the smooth of pavement-height is kept, it is opposite to the constraint of the elastic expansion range of filling block 3 in expansion joint
It is small.The side of isometry block 1, rough surface, or have boss or have shrinkage pool, or have zigzag or be evenly equipped with wing plate 1.1, or have filling
Hole 1.2, effect is can be tighter with the attachment of filling block 3, and what is be interconnected is stronger.Three 1.1 female surfaces of wing plate of isometry block 1
Long-pending length-width ratio is 1:1.Connection strap 2 buries muscle 2.1 above, and effect is stronger to catch filling block 3, there is mounting hole 2.2,
Effect is connect with the road surface above bridge plate 5.Filling block 3 is connected to each isometry block 1, only plays the telescopic action at expansion joint and stops
Water effect, no longer takes on the load-bearing effect for wheel.There is strip of paper used for sealing 4 between road surface above bridge expanssion joint and bridge plate 5, if
4 good airproof performance of strip of paper used for sealing, the waterstop 6 between side bridge plate 5 just only play preventing standby.Isometry block 1 can be fabricated to respectively
Kind shape can make of metal or concrete.
