Technical field

The invention belongs to building engineering fields, more particularly to a kind of assembled bridge pier.

Background technique

Prefabrication and assembly constructionization construction has gradually substituted traditional poured in place concrete construction at present, is widely used in bridge Construction field carries out element precast its main feature is that concentrating in factory, makes full use of modernization template and maintenance technology, component complete On-site consolidation is carried out to bridge location at prefabricated rear transport, the component of dispersion is connected to become entirety using node interconnection technique, is met Service performance under operation and extreme loading condition, to realize that industrialization, automation and the assembling of bridge member production are applied Work.

Bridge pier be in bridge more than two holes and two holes in addition to the abutment that both ends are connected with embankment remaining intermediate supports Structure.Bridge pier is mainly made of top cap, pier shaft.Abutment is mainly made of top cap, abutment body.Bridge pier be divided into solid pier, column pier and Framed bent pier etc..Rectangle pier, tip shape pier, round pier etc. can be divided by flat shape.The material of building bridge pier can use timber, stone Material, concrete, armored concrete, steel etc..The position of bridge pier and bridge superstructure it is point closely related across arranging, should pass through Technology and economy comparison determines.At present for the bridge construction in highway, local road and urban road, the top knot of bridge Structure (i.e. traveled portion) has been realized in prefabrication and assembly construction construction, and the substructure (i.e. bridge pier part) of bridge still continues to use tradition Technology carries out cast in situs construction, and in bridge construction, encounters that the construction spaces such as cross a river, the road across Hu Huokua are narrow, construction work Phase is short and the demanding situation of construction quality, conventional poured in place concrete arrangement and method for construction need more template, foot hand Frame, the duration is longer, and cast in situs quality and precision are difficult to ensure, and the personal safety of site operation worker cannot also be protected Card, there are some potential safety problemss.In existing house building technology, the floor of light house structure mainly using In-situ reinforced concrete slab form.In-situ reinforced concrete slab is needed to carry out formwork at the construction field (site), assembling reinforcement, be poured The multiple tracks working procedure such as concrete, maintenance, demoulding is built, and it is mountable to need floorslab concrete maintenance to reach design strength rear Superstructure.Therefore, haves the defects that construction process complexity.

Summary of the invention

In order to solve above-mentioned technical problem, the present invention provides a kind of assembled bridge piers, mainly for exploitation one The assembled bridge pier of the novel good integrity of kind, simple structure, and reduce construction materials, reduce waste.

The technical solution adopted by the invention is as follows:

A kind of assembled bridge pier, including pedestal, bridge column, cushion cap, cast-in-place concrete, prepared screw-bolt hole, high-strength bolt, the pedestal Centre internally prefabricated reserved link slot, in the outside Prefabricated L-shaped steel plate of the inside middle of pedestal；The bridge column bottom it is prefabricated to Steel tank is reserved in the overhanging connection rib in outer bottom, the prefabricated bottom of the bottom internal of bridge column, and prefabricated top is overhanging outward on bridge column top Rib is connected, inwardly steel tank is reserved at prefabricated connecting groove and top on bridge column top；The cushion cap bottom prefabricated cushion cap bottom outward Overhung ribs, are prefabricated with junction steel plate inside cushion cap, the inside prefabricated cushion cap groove in cushion cap bottom；The pedestal and bridge column pass through bridge column The overhanging connection rib of bottom and the reserved link slot of pedestal, which cooperate, to be overlapped, and by the overhanging connection rib in bottom and is reserved by high-strength bolt Link slot connection, the L-type steel plate of chassis interior and the bottom of bridge column reserve steel tank and are connected as entirety by high-strength bolt, pre- It lingers on and fills cast-in-place concrete in access slot；The bridge column and cushion cap by the overhanging connection rib on bridge column top and connecting groove with hold The cushion cap bottom overhung ribs and cushion cap groove of platform cooperate overlap joint, and steel tank is reserved at the inside junction steel plate of cushion cap and the top of bridge column Being cooperatively connected by high-strength bolt becomes whole.

Further, the position of the overhanging connection rib of the reserved link slot of the pedestal and the bottom of bridge column matches, in advance The size for lingering on the size connection rib more overhanging than bottom of access slot is big；The cast-in-place concrete filled at the reserved link slot of pedestal is complete Cover the overhanging connection rib in bottom.

Further, steel tank is reserved in the bottom of the bridge column and the L-type steel plate of pedestal matches, on L-type steel plate Prepared screw-bolt hole matches with the prepared screw-bolt hole on bridge column and pedestal.

Further, the overhanging connection rib in top of the cushion cap bottom overhung ribs of the cushion cap and cushion cap groove and bridge column and Connecting groove matches, and the size that the junction steel plate of steel tank and cushion cap is reserved at the top of bridge column matches.

Further, the upper surface of the horizontal steel plate for the L-type steel plate stated is flushed with the lowest part surface of reserved link slot.

Compared with prior art, the advantages of the present invention are: the present invention make bridge pier have good globality, Connection, simple structure convenient for bridge pier and floorings, easy for construction, shortening short construction period, reduction waste, simple structure are equivalent Fruit greatly improves construction efficiency.
