Description

A kind of steelframe bridge structure quickly spliced
Technical field
The utility model relates to one kind to build a bridge, and be specifically a kind of steelframe bridge structure quickly spliced.
Background technique
In existing highway bridge structure type, there are beam bridge, arch bridge, cable-stayed bridge, suspension bridge and composite bridge, wherein with beam bridge It is most commonly seen.Be bent cap above bridge pier in bridge structure, be spherical bearing structure between bent cap and top beam body, bent cap and Bearing pad stone is equipped between spherical bearing, spherical bearing is located on bearing pad stone, between bent cap and bearing pad stone and beam body and Steel plate is equipped between spherical bearing.However, beam bridge is during construction and operation, and due to being influenced by wind-force, home position The superstructure beam body of correct concrete beam bridge will appear lateral deviation phenomenon, and leading to bridge structure, there are safety built on the sand Hidden danger.
Bridge refers generally to be erected in rivers,lakes and seas, the structures for making traffic etc. that can smoothly pass through.It is modern to adapt to The transportation industry of high speed development, bridge be also extended to across mountain stream, unfavorable geology or meet other traffic need and set up make Current more convenient and fast building.Bridge is generally made of superstructure, substructure, support and attached structure, top knot Structure is also known as bridge span structure, is across the primary structure of obstacle;Substructure includes abutment, bridge pier and basis;Support is spanning knot The load transfer device of the bearing place setting of structure and bridge pier or abutment;Attached structure then refer to transition slab at bridge head, truncated cone banking, shore protection, Training works etc..
It is found by retrieval, the utility model of patent No. CN201721924449.2 discloses one kind and is equipped with horizontal wind resistance The bridge structure of device, is related to field of bridge construction, the spherical bearing being arranged including at least two along direction across bridge, two balls The side of shape support away from each other is respectively provided with a horizontal wind-proof device, and two horizontal wind-proof devices are symmetrically set along direction across bridge It sets, the horizontal wind-proof device includes the support base and at least one horizontally disposed top-pushing mechanism of a fixed setting, the pushing tow Mechanism one end is set on the support base, and the other end is held in side of the spherical bearing far from bridge center.
A kind of dual deck bridge structure for reducing whole height of the disclosure of the invention of patent No. CN201610332550.2, packet Shared pier stud, upper layer railway beam portion and lower layer's railway beam portion are included, pier stud is shared and is made of lower part solid pier and top twin shaft pier, on The upper layer railway stringer of layer railway beam portion is located at shared pier stud by the way that support body frame is arranged outward in the two sides of same level On the twin shaft pier of top, supporter is the prestressed reinforced concrete construction of lateral widening and tensioning transversely prestressed bars.
A kind of bridge structure that civil small-scale quickly splices of the disclosure of the invention of patent No. CN201721481798.1, including Multiple inserting columns and bridge plate, the top of each inserting column are fixedly connected to bridge pier, and each bridge plate is erected on bridge pier, One end of each bridge plate is equipped with fixed plate, and each one end of the bridge plate far from fixed plate offers and fixed plate phase The fixing groove mutually cooperated opens up on the two sidewalls of each fixed plate there are two fixture block groove, two fixture block grooves it is interior Portion is mounted on spring, and two opposite one end of the spring are mounted on wedge-shaped fixture block, and two wedge-shaped fixture blocks are close to bullet One end of spring is respectively connected with traction rope, and two traction ropes are connected with drawstring far from one end of wedge-shaped fixture block jointly.This is practical New structure is simple, convenient for operation, forms a firm bridge provided with a series of components convenient to use, while conveniently Installation and removal, greatly improve the traffic convenience in rural area and suburb, efficiently convenient, are worthy to be popularized.
Currently, in Bridge Design, due to the requirement of the factors such as geological conditions, navigational clearance, sometimes must using greatly across Diameter, therefore frequently with cable-stayed bridge and suspension bridge scheme.But with the increase of across footpath, the cost of cable-stayed bridge and suspension bridge be will increase very It is more.In addition, existing bridge structure is complicated, difficulty of construction is big, and consumptive material is more, and common rural area, suburb modernization construction are unsound, Drop down water, detour area, locals can only rely on less cost, and a small amount of manpower, simple tool, the less time builds Simple bridge, thus be badly in need of it is a kind of facilitate passage, reduce the used time, guarantee the safe steelframe bridge structure quickly spliced.
