Abstract
The utility model discloses four-track line space curved surface M type bridge pier, it comprises pier top cap (1), pier shaft (3) and basis (4), it is characterized in that: described pier shaft (3) is that three intervals are arranged and the pier stake (3.3) that basis (4) is connected; The pallet (2) of transition is provided with between described pier top cap (1) and pier shaft (3); Described pallet (2) comprises upper and lower two parts, is pallet top (2.1) and pallet bottom (2.2) respectively; Described pallet bottom (2.2) comprises two arches (2.2.1) and three spaced apart arch springings (2.2.2), and three described arch springings (2.2.2) are built with three pier shaft (3) one_to_one corresponding respectively and are integrated; It solve the shortcoming of the face crack that existing four-track line bridge pier solid pier causes because hydration heat of concrete is excessive, the utility model has saves concrete masonry, advantage that bridge pier anti-seismic performance is superior.
Description
Technical field
The utility model relates to the technical field of bridge pier, more specifically a kind of four-track line space curved surface M type bridge pier.
Background technology
The development of China's economy and society has promoted the construction of railway, bridge occupies higher proportion planning to build in circuit, and particularly along with the development of urbanization, land resources is extremely nervous, the line position of multiple line railway is subject to increasing restriction, and the trend that multiple line railway walks abreast is common all the more; It is that bridge direction across bridge is wider, the horizontal build of bridge pier is excessive, the bridge pier concrete masonry scale of construction is comparatively large that existing four-track line bridge pier designs ubiquitous problem, and many difficult problems such as face crack, transverse direction is roomy, moulding is heavy, four line modified line spacing bridge abutment integral designs that solid pier causes because hydration heat of concrete is excessive.
Summary of the invention
The purpose of this utility model is for the larger problem of the existing bridge pier concrete masonry scale of construction and proposes a kind of four-track line space curved surface M type bridge pier.
The utility model four-track line space curved surface M type bridge pier, it comprises pier top cap, pier shaft and basis, and described pier shaft is that the pier stake be connected with basis is arranged at three intervals; The pallet of transition is provided with between described pier top cap and pier shaft; Described pallet comprises upper and lower two parts, is pallet top and pallet bottom respectively; Described pallet bottom comprises two arches and three spaced apart arch springings, and three arch springings of two described arches are built with three pier shaft one_to_one corresponding respectively and are integrated.
In technique scheme: described pier top cap comprises cap bottom surface; Be pallet top between described cap bottom surface to pier shaft transition vault; Described pallet top front face and side all adopt round surface structure.
In technique scheme: described arch comprises the pier shaft transition arch end of pier shaft transition vault and the bottom being positioned at top; Described pier shaft transition vault is pallet bottom between the pier shaft transition arch end; Described pallet bottom adopts M type bicircular arcs arch structure.
The utility model tool has the following advantages: 1, the utility model adopts M type arch structure to overcome laterally roomy, the heavy image appearance of four-track line bridge pier well, improves the visual effect that bridge pier is light and handy, unfold; 2, the utility model adopts and reduces bridge pier concrete masonry amount to greatest extent, avoids the face crack that solid pier causes because hydration heat of concrete is excessive; 3, adopt reinforced concrete structure, significantly improve bridge pier structure anti-seismic performance, fully demonstrated structure anti-earthquake ductility design concept.

Detailed description of the invention
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not form limitation of the invention, only for example; To become clearly and easy understand advantage of the present invention by illustrating simultaneously.
With reference to shown in Fig. 1-6: the utility model four-track line space curved surface M type bridge pier, it comprises pier top cap 1, pallet 2, pier shaft 3 and basis 4.
Described pier top cap 1 is the supporting beam portion of whole bridge pier, and its cross section is rectangle; Described pier top cap 1 comprises cap bottom surface 1.1; Be described pallet 2 between described pier top cap 1 and pier shaft 3;
Described pallet 2 comprises upper and lower two parts, is pallet top 2.1 and pallet bottom 2.2.
The cap bottom surface 1.1 of described pier top cap 1 is described pallet top 2.1 between pier shaft transition vault 3.1; The front on described pallet top 2.1 and side all adopt round surface to be formed, and wherein four corners is that the large corner cut of pier shaft to be progressively transitioned at the bottom of the cap of pier top not corner cut; Described front, pallet top 2.1 and side all adopt round surface structure.
Described pier shaft transition vault 3.1 is described pallet bottom 2.2 between the pier shaft transition arch end 3.2; Described pallet bottom 2.2 comprises two arches 2.2.1 and three spaced apart arch springing 2.2.2; Three described arch springing 2.2.2 build with three pier shaft 3 one_to_one corresponding respectively and are integrated.
Described pier shaft 3 is that three intervals are arranged and the pier stake 3.3 that basis 4 is connected; The bottom of three pier stakes 3.3 is all built with described basis 4 and is integrated.
Wherein arch structure edge be the large corner cut of pier shaft progressively transition be vault not corner cut; Described pallet bottom 2.2 adopts M type bicircular arcs arch structure.
Main pier and pier shaft plan divide two joints to build, and first time builds the following pier shaft 3 of pallet; Second time builds pallet 2 and top cap cap 1 forms M type bicircular arcs arch structure.
Above-mentioned unspecified part is prior art.
