Abstract
The utility model discloses a transverse arc-shaped sloping bridge pier which comprises an upper-part pier body and a lower-part pier body. A transverse slope of the upper-part pier body is a linear one, the transverse slope of the lower-part pier body is an arc-shaped one, and the arc-shaped slope is tangential to the linear slope. With smart design and reasonable structure, the transverse arc-shaped sloping bridge pier saves concrete masonry on the pier bodies, effectively reduces the cost, and improves the landscape effect of the high pier.
Description
Technical field
The utility model relates to a kind of bridge pier that is used for railroad bridge, relates in particular to a kind of horizontal arc and puts the Ramp bridge pier.
Background technology
Along with the construction of the develop rapidly of China's electric railway, particularly high-speed electric railway, high Dun Dakuaqiaoliang continues to bring out.This type of bridge needs the safety of enough lateral stiffnesses to guarantee that train is runed at a high speed, and the physical dimension that increases high pier is the most direct method effectively.At present, stride prestressed concrete continuous rigid frame railway bridge greatly at high pier, be the following two kinds of structures of the many employings of lateral stiffness that guarantee structure: one, pier shaft laterally adopts the heavy grade staight slope, improves rigidity by increasing the pier shaft sectional dimension.The pier shaft sectional dimension of this structure is linear increasing.When reaching rigidity requirement, the pier shaft bricklaying increases more.Simultaneously, the landscape effect dullness of this type of pier shaft can not satisfy the requirement of modern railways landscape.Two, pier shaft adopts the secondary straight line to put the slope, and the pier shaft bottom is selected the slope ratio bigger than top for use, pier shaft bricklaying and sectional dimension more can be concentrated on the pier shaft bottom, and structural focus is moved down.The secondary straight line of this structure pier shaft is put the slope and is staight slope, and the size at the bottom of the pier can only linearly increase, and can't effectively divide quality and the concentrated pier bottom that needs most quality and rigidity that is increased in of rigidity.Therefore, the pier shaft concrete masonry has the space of very big saving.Simultaneously, this type of pier shaft also shows dull in appearance.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of horizontal arc to put the Ramp bridge pier.This bridge pier is skillfully constructed, rational in infrastructure, saved the pier shaft concrete masonry, effectively reduce cost, improved the landscape effect of high pier.
For achieving the above object, the utility model solves the technical scheme that its technical problem adopts and is:
A kind of horizontal arc is put the Ramp bridge pier, comprises top pier shaft and bottom pier shaft, and the cross fall of described top pier shaft is a staight slope, and the cross fall of bottom pier shaft is the arc slope, and this arc slope is tangent with staight slope slope line.
As preferably, the aspect ratio of described top pier shaft and bottom pier shaft is 3～1:1; Further preferred, the aspect ratio of described top pier shaft and bottom pier shaft is 2～1:1.
As preferably, described arc slope is circular arc slope or parabolic arc slope.
Inventor of the present utility model finds by a large amount of computational analysis in research process: present way is by adopting certain sloping ratio to increase the pier shaft size, and the pier shaft sectional dimension can only linearly increase.So, propose to adopt arc to put the slope, comprise circular arc, parabolic arc etc.Put the slope by arc, the pier shaft sectional dimension is that quadratic power, three cubed relation increase.The linearity of comparing is put the slope, and under the situation of isodose pier shaft bricklaying, more bricklaying concentrates on the pier shaft bottom, has increased the rigidity of structure effectively, and corresponding the moving down of center of gravity of structure simultaneously helps improving the train operation performance of railroad train.The cross fall of top pier shaft is a staight slope, and the cross fall of bottom pier shaft is the arc slope, has improved the landscape effect of high pier.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
The utility model is skillfully constructed, rational in infrastructure, saved the pier shaft concrete masonry, effectively reduce cost, improved the landscape effect of high pier.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the lateral view of Fig. 1.
Mark among the figure: 1 staight slope, 2 arc slopes.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Embodiment: as shown in Figure 1, 2, a kind of horizontal arc is put the Ramp bridge pier, comprises top pier shaft and bottom pier shaft, and the cross fall of described top pier shaft is a staight slope, and the cross fall of bottom pier shaft is the arc slope, and this arc slope is tangent with staight slope slope line.
As preferably, the aspect ratio of described top pier shaft and bottom pier shaft is 3～1:1; Further preferred, the aspect ratio of described top pier shaft and bottom pier shaft is 2～1:1.As preferably, described arc slope is circular arc slope or parabolic arc slope.
The pier shaft top width is basic wide consistent with beam body case, and the top pier shaft adopts the linear slope of putting, to guarantee that the Dun Liang connection is convenient, power transmission is smooth and easy.The bottom pier shaft adopts arc to put the slope, and lower curved pier shaft and top linear pier shaft are tangent with assurance outward appearance and stressed smooth and easy.Bottom pier shaft arc radius can draw according to the rigidity requirement inverse of pier shaft.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
