Description
Technical field
The present invention relates to bridge expanssion joint field, be specifically related to a kind of control expansion joint equally spaced double link of central sill
Mechanism.
Background technology
Bridge expanssion joint refers to the requirement for meeting bridge floor deformation, by between two beam-ends, beam-ends and abutment
Between or the articulated position of bridge on expansion joint is set, employing modulus type expansion joint general for Longspan Bridge.
Typically there are two kinds of versions, multi-support type and single support type in existing modulus type expansion joint, and multi-support type is adopted
With crossbeam and central sill frame mode one to one, a displacement controlling box arranges multiple bearing cross beam, each supporting
Same middle joist steel of crossbeam is fixed, and in the case of stroke requires relatively greatly, its central sill and crossbeam are more, position
Move control chamber the biggest, be just difficult to manufacturing and installing, so the modulus expansion joint of multi-support type
May be only available for the displacement situation less than 560；Single all central sills of support type are all supported on same
Holding on crossbeam, and can slide along bearing cross beam direction, bearing cross beam is supported in the displacement controlling box at two ends.
In existing bridge modulus expanded joint structure, wherein case bay uses compression spring or shear spring phase
Between Hu, compression stress or shearing force balance regulate, and in the case of big displacement quantity, crossbeam frictional resistance increases, bullet
Spring regulating power relative drop, easily occurs that each beam stretches non-uniform phenomenon.And control spring typically to use
Macromolecular material is made, and long-time use is the most aging, and its elastic performance reduces, it is impossible to accurately ensure central sill
Seam broad gap is consistent, it is possible to causes the water-proof sealing rubber strip between central sill to tear, has had a strong impact on expansion joint
The endurance quality of structure.Use and control spring control uniform mechanism structure complexity, during each control spring passes through
Liangping weighing apparatus internal force, after a certain central sill destroys, is difficult to individually remove this central sill, and need to change whole flexible
Seam, brings great inconvenience to maintenance.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of control expansion joint equally spaced double connecting rod of central sill,
Can guarantee that under any stroke, case bay is consistent, is greatly improved the endurance quality of expanded joint structure.
The present invention solves the problems referred to above by techniques below means: a kind of control expansion joint central sill is equally spaced double
Linkage, including two side bars and many central sills being arranged between two side bars, between side bar and central sill
And between central sill, having water-proof sealing rubber strip, central sill is supported on many crossbeams, and described central sill is by supporting bullet
Spring is connected with holddown spring and crossbeam, and crossbeam two ends are arranged in displacement controlling box by bearing, also includes setting
Put first connecting rod below central sill, that connected and second connecting rod, first connecting rod and second connecting rod by rotating shaft
Free end be rotationally connected with the bearing pin being anchored in mixed earth, described first connecting rod and second connecting rod first-class between
Away from being provided with many slide bars, all of central sill is respectively connected with slide bar coupling by a connected chute.
Further, the equally spaced double connecting rod in described control central sill expansion joint is to arrange according to expansion joint length
Two overlap or overlap more.
Beneficial effects of the present invention: the control expansion joint equally spaced double connecting rod of central sill of the present invention, including
Being arranged on first connecting rod below central sill, that connected and second connecting rod by rotating shaft, first connecting rod and second is even
The free end of bar is rotationally connected with the bearing pin being anchored in mixed earth, and described first connecting rod and second connecting rod are first-class
Spacing is provided with many slide bars, and all of central sill is respectively connected with slide bar coupling by a connected chute,
The bridge expanssion joint of this structure, controls the spacing of all central sills by double connecting rod, with traditional by bullet
Property control element and control the spacing of central sill and compare, can accurately ensure that the spacing between central sill is consistent, and this structure
It is convenient to change, and safeguards simple, can be greatly improved the endurance quality of bridge expanssion joint.
Accompanying drawing explanation
With embodiment, invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is that intention is overlooked in the general assembly of the present invention；
Fig. 2 is A-A structural representation；
Fig. 3 is B-B structural representation.
Detailed description of the invention
Below with reference to accompanying drawing, the present invention is described in detail, as shown in Figure 1 to Figure 3: this control expansion joint
The equally spaced double connecting rod of central sill, including being anchored at two side bars 1 of bridge plate seam crossing both sides and being arranged on
Many central sills 2 between two side bars, have water-proof sealing rubber strip 3, limit between side bar and central sill and between central sill
Having many crossbeams 4 below beam and central sill, described central sill is connected by bearing 5 and beam supporting, crossbeam two
Hold to be supported by bearing and displacement controlling box 6 and be connected, also include being arranged on below central sill, by rotating shaft 7
Connect first connecting rod 8 and second connecting rod 9, first connecting rod and second connecting rod free end be anchored at mixed mud
Bearing pin 10 in soil is rotationally connected, and described first connecting rod and second connecting rod are equidistantly provided with many slide bars
11, all of central sill is respectively connected with slide bar 11 coupling by a connected chute 12, whole flexible
Device arranges a displacement controlling box 6 every 2m, and the length of first connecting rod and second connecting rod can be with stroke
Increase and increase, control the spacing between central sill by double connecting rod, spacing can be made uniform, be greatly improved knot
The endurance of structure.
As the further improvement of technique scheme, the described control expansion joint equally spaced double connecting rod of central sill
For symmetrically arranged many sets, the reliability and stability that spacing controls can be improved.
Finally illustrating, above example is only in order to illustrate art scheme of the present invention and unrestricted, although with reference to relatively
The present invention is described in detail by good embodiment, it will be understood by those within the art that, can to the present invention
Art scheme is modified or equivalent, and without deviating from objective and the scope of the present invention program, it all should be contained
In the middle of profit claimed range of the present invention.
