Abstract
The utility model relates to an iron road bridge deck -molding mound. At the railway of mountain area or the construction of loess plateau area, the bridge depth of beam is higher, for the requirement that reaches indisputable road bridge roof beam design specifications, if continue to adopt the traditional structural style of pier will lead to pier shaft and foundation concrete quantity huge, be unfavorable for practicing thrift the construction investment. The utility model discloses a vertical single -column, the single -column bottom sets up four bracings that the downward radiation is scattered, and every bracing bottom all is provided with the stake of independent cushion cap and cushion cap lower part, be provided with the crossbeam between the middle part of adjacent bracing, be provided with the binder between the adjacent cushion cap. The utility model discloses indisputable road bridge roof beam design specifications's strict demand can be satisfied, pier shaft and foundation concrete's quantity can be effectively reduced again, reduce project cost, along with the reduction of pier shaft and foundation concrete quantity, the structure becomes and is full of gently for the earthquake that the pier received under the seismic action is done all can also showing and is reduced, has further reduced pier shaft and foundation concrete's quantity.
Description
Technical field
This utility model belongs to bridge structure technical field of buildings, is specifically related to a kind of railway bridge deck-molding pier.
Background technology
Bridge pier is the important component part of bridge, and its effect is that beam portion load is passed to basis.Railroad bridge design rule
The requirement of model is more strict, and bridge pier is it is necessary to have enough rigidity, strength and stability, to bear dead load, live load of train, wind
Load and the effects such as power, temperature, earthquake.
The traditional version of railroad bridge bridge pier mainly has nose circle shape, rectangle, transom pier, double thin wall pier, V support etc., suitable
For the situation that bridge height is relatively low.At the railway that mountain area or Loess Plateau are built, bridge depth of beam is higher, in order to reach
The requirement of railroad bridge design specification, the version as continued to use bridge pier traditional will cause pier shaft and base concrete to be used
Measure huge, be unfavorable for saving construction investment.It is thus desirable to research and develop the version that a kind of railway bridge deck-molding pier is novel, meeting ferrum
On the premise of road and bridge beam design specification requires, reduce pier shaft and the consumption of base concrete.
Summary of the invention
The purpose of this utility model is to provide a kind of railway bridge deck-molding pier, when railroad bridge height is higher, this kind of structure
Form, on the premise of meeting the requirement of railroad bridge design specification, can reduce the consumption of pier shaft and base concrete.
The technical scheme that this utility model is used is:
A kind of railway bridge deck-molding pier, it is characterised in that:
Including vertical only post, only column bottom arranges four diagonal braces that downward radiation is scattered, and is respectively provided with bottom each diagonal brace
There are independent cushion cap and the stake of cushion cap bottom.
It is provided with crossbeam between the middle part of adjacent diagonal brace.
It is provided with binder between adjacent cushion cap.
This utility model has the advantage that
In terms of direct benefit, railway height pier bridge uses the version of turriform pier, compares the structure shape that bridge pier is traditional
Formula, can meet the strict demand of railroad bridge design specification, can effectively reduce again the consumption of pier shaft and base concrete, reduces
Construction costs.In terms of indirect benefit, along with pier shaft and the minimizing of base concrete consumption, structure becomes to be full of gently so that ground
Under shake effect, the seismic force suffered by bridge pier also substantially reduces, and further reduces the consumption of pier shaft and base concrete.
Accompanying drawing explanation
Fig. 1 is this utility model vertical structure figure.
Fig. 2 is this utility model lateral junction composition.
In figure, the only post of 1-, 2-diagonal brace, 3-crossbeam, 4-cushion cap, 5-binder, 6-stake.
Detailed description of the invention
Below in conjunction with detailed description of the invention, this utility model is described in detail.
This utility model relates to a kind of railway bridge deck-molding pier, and bridge pier is the version of turriform, including vertical only post 1,
Solely bottom post 1, four diagonal braces 2 that downward radiation is scattered are set, bottom each diagonal brace 2, are provided with independent cushion cap 4 and cushion cap 4
The stake 6 of bottom.It is provided with crossbeam 3 between the middle part of adjacent diagonal brace 2.It is provided with binder 5 between adjacent cushion cap 4.
The application is when railroad bridge height is higher, and this kind of version is before meeting railroad bridge design specification and requiring
Put, the consumption of pier shaft and base concrete can be reduced.
Content of the present utility model is not limited to cited by embodiment, and those of ordinary skill in the art are new by reading this practicality
Type description and the conversion of any equivalence of taking technical solutions of the utility model, be claim of the present utility model institute
Contain.
