Description
Technical field
The present invention relates to a kind of integrated form single track beam end pre-embedded devices, for track girder fine strain of millet end, belong to rail traffic skill
Art field.
Background technology
Country is greatly developing urban track traffic at present, and wherein straddle-type monorail is may widely apply in the future one
Kind form, but domestic straddle-type monorail is applied also seldom at present, and only Chongqing was established in 2000 or so Introduced from Japan technologies
Several straddle-type monorail circuits, existing straddle-type monorail use PC track girders.
Structure shown in Fig. 1 is tradition PC track girder fine strains of millet end built-in fitting schematic diagram, and the cross section of such PC track girders is general
No more than 900mm（It is wide）×1500mm（It is high）, the pre-buried bearing embedded board in corresponding beam-ends above its bearing 1 of PC track girders 2
And cast-in fixing bolt 3, steady wheel castellated plates built-in fitting 4, prestressed anchor anchor backing plate 5, directive wheel castellated plates built-in fitting 6, walking
Form of gear tooth plate built-in fitting 7.Due to wanting this pre-buried many built-in fitting, space is at full stretch.This structure design can bring one
Series of problems：Beam-ends attachment to be mounted is more during precast beam, and model sheetinstallat position is complicated, the bulk between each built-in fitting
It should not control, construction time and the bad guarantee of construction quality；And concrete is when anchorage tensioning, shrinkage and creep, vehicle pass through
Under Fatigue Load, the concrete stressing conditions between built-in fitting are poor, are susceptible to destruction；Existing PC tracks beam span
Generally only 18~22m, pier, the pier stud for building needs are relatively more, when town road is laid out, across the ability of town road
Also it is weaker.
Therefore, patent of the present invention carries out comprehensive analysis by the bearing, prestressed anchor, telescopic device to PC track girders,
It proposes a kind of integrated solution of beam-ends built-in fitting, can effectively solve problem above, and can be carried for external prestressing
For anchorage point, so as to improve the span of PC track girders, engineering construction period and cost are reduced, improves the cross-line energy of PC track girders
Power.
Invention content
The goal of the invention of the present invention is：In view of the above problems, it is pre-buried to provide a kind of integrated form single track beam end
Device.
The technical solution adopted by the present invention is such：
A kind of integrated form single track beam end pre-embedded device including track girder, bearing, anchor backing plate, holder top embedded board, is stretched
Device built-in fitting, installation anchorage and corrugated pipe connector on the anchor backing plate set holder top on the holder top embedded board
Cast-in fixing bolt, the anchor backing plate are fixedly connected with holder top embedded board.
Anchor backing plate is fixedly connected after collection is integrated by above-mentioned technical proposal with holder top embedded board, can will be original
The active force of anchor backing plate and holder top cast-in fixing bolt peptizaiton in concrete fine strain of millet end becomes an entirety to load, and allows mixed
Being more uniformly stressed for solidifying soil fine strain of millet end, is more not readily susceptible to damage；During fabrication, required template is less, and arrangement is got up more
Convenient and time-saving, construction quality is easier to be guaranteed；Former holder top cast-in fixing bolt in need can be shortened, it is pre- so as to increase
The space of stress steel bar arrangement.
Preferably, the telescopic device built-in fitting is fixedly connected with anchor backing plate and holder top embedded board.Further
It is preferred that the telescopic device built-in fitting includes traveling wheel walking surface built-in fitting, directive wheel walking surface built-in fitting and steady wheel walking
Face built-in fitting, the traveling wheel walking surface built-in fitting are fixedly connected with anchor backing plate top, the directive wheel walking surface built-in fitting
Anchor backing plate top both sides are fixedly connected on, the steady wheel walking surface built-in fitting is fixedly connected on anchor backing plate lower part both sides.
Telescopic device built-in fitting is also integrated together, it can be to avoid each component of telescopic device built-in fitting and anchor backing plate, holder top
Interference between cast-in fixing bolt in this way integrates three original individually separated pre-buried structures, in prefabrication of beam, just
It only needs to carry out one-time positioning and pre-buried, the relative position between three pre-buried structures can accurately be ensured, be shortened prefabricated
The manufacturing cycle of beam improves the prefabricated precision of beam body.
Preferably, the holder top embedded board bottom sets external anchor point.Further preferably, the external anchoring
Point is combined together or is provided separately with bearing.The external anchor point of setting can bear for installing external prestressing anchorage
Pressure and moment of flexure further improve the bearing capacity of track girder and cross-line ability, so as to further increase track girder
Span reduces the pier stud quantity of entire circuit, reducings the construction costs.
