Abstract
The invention relates to an assembly-type bridge and an erecting method, and the method comprises the step of erection of pre-assembly units and a bridge of the structure. The pre-assembly unit consists of a bridge-span main girder pre-assembly unit and a guide girder pre-assembly unit, and is of a three-dimensional structure. The bridge-span main girder pre-assembly unit is bigger, and the guide girder pre-assembly unit is smaller, and the bridge-span main girder pre-assembly unit and the guide girder pre-assembly unit are set together in a nested manner. A plurality of pre-assembly units are connected to form a bridge-span main girder and a guide girder. The guide girder can slide back and forth in the main girder. The method can achieve the quick assembly and disassembly of the bridge, simplifies the assembly and disassembly operation of a conventional nose girder, and can be widely used for rescue and relief and military action.
Description
Technical field
The present invention relates to the erection of a kind of packaged type bridges, especially packaged type bridges/remove receiving method.
Background technology
Packaged type bridges are also referred to as reassembling type bridge, are that the highly important bridge rush-repair in home and abroad robs frame equipment, and it is representative
Product is assembly type steel bridge on highway.Assembly type steel bridge on highway is widely used in the motor-driven guarantee of army, at ordinary times rescue and relief work and its people
In economic construction.Because assembled highway bridge is readily transported, using flexible, the bridge of different length can be as needed set up into
Beam, bridge passes through functional, is paid attention to by army, national communication war preparedness department and road and bridge company, and its performance is obtained not
It is disconnected to improve.
The assembled rigid unit of existing several assembly type steel bridge on highway is mainly plane girder and linear stick-type members composition, structure
System is essentially identical, is base-supporting bridge, and basic erection mode is nose frame (being also nose girder) guidance mode.Patent announcement number
Disclose on patent announcement for " CN 201372404Y " a kind of " wide-span ", the truss of the bridge by
Lamellar triangular web member and H type metal chord members are assembled.The patent announcement of patent announcement number " ZL201218003212.7 "
" a kind of chord member of reassembling type bridge ".Girder involved by above-mentioned patent is constituted by plane girder or linear stick-type members.Its
Main deficiency is that the number of components is more, and joint connection in site workload is big, sets up speed slower." assembly type steel bridge on highway uses handss to data
Volume ", " ZB-200 type assembly type steel bridge on highway service instructions ", " ZB-450 type assembly type steel bridge on highway working services are said
The erection method that bright book " is introduced is nose frame guidance mode.Nose frame used by the method is assembled using girder truss element, sets up
When spanning front end install nose frame, push spanning and nose frame to opposite bank together.After nose frame reaches opposite bank rock and roll, with spanning
Continue to push, need to remove nose frame in time, the main deficiency of the method is the installation of nose frame and removes laborious time-consuming.Not only in frame
If when need install and remove nose frame, remove receive bridge when be also required to reinstall and remove nose frame, workload is larger, is unfavorable for
The fast erecting of bridge and remove receipts.Especially when bridge span is larger, the use Nose rack structure form adopted is complicated, common constructor
Member is difficult to grasp, and affects erection construction safety.
Bailey bridge and MDB bridges (Mabey Delta Bridge) used by Britain, the U.S. etc., with China's assembled highway
Steel bridge is similar, and erection method is also adopted by nose frame guiding and sets up.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of packaged type bridges, by the form for being assembled into preassembled unit,
Synchronized links form the girder and nose girder of spanning, to reduce the consolidation service amount of spanning, simplify the assembling process of nose girder, need to be
Set up/remove time receiving installation, nose girder removed, to improve bridge erection speed.
In order to solve above-mentioned technical problem, the present invention includes the structure of packaged type bridges, and sets up/remove receipts step accordingly
Suddenly.The packaged type bridges constitute agent structure by girder, nose girder and crossbeam etc..Girder is made up of girder preassembled unit, nose girder
It is made up of nose girder preassembled unit, girder preassembled unit and nose girder preassembled unit can be respectively sections pattern, and nose girder preassembled unit is embedding
It is enclosed within inside girder preassembled unit, forms preassembled unit, joined end to end by pin joint, bolt or other modes, is respectively combined into
Girder and nose girder.First by nose girder by release in girder during erection, cantilever extension arrives at opposite bank, and it is right that spanning relies on again nose girder to slide to
Bank.Spanning is reached behind opposite bank, and nose girder aligns with spanning, no longer removes.
Described girder preassembled unit includes the connector between the carrier bar and carrier bar of the left and right sides, will by crossbeam
Two preassembled units (can also be multiple) hold together, and constitute bridge span structure.Crossbeam both can be located at preassembled unit bottom
Form base-supporting bridge, it is also possible to form car for deck bridge positioned at preassembled unit top.
Described nose girder preassembled unit is nested in girder preassembled unit, can be slided in girder preassembled unit.Prepackage is single
The length of unit, is determined by Lifting Capacity when transport or erection.When transport or erection, nose girder preassembled unit can be filled by locking
Put fixed in girder preassembled unit.
Described erection/remove receipts step is：During erection, nose girder is stretched out by traction in girder or push, can extremely keep bridge
Across the precalculated position of balance, locking nose girder prevents the relative slip between nose girder and girder.Push spanning to opposite bank again, to leading
Opposite bank rock and roll bearing is costed in beam front end, releases the locking system between nose girder and girder, and nose girder is consolidated with opposite bank rock and roll bearing
It is fixed.Promote girder to slide to opposite bank along nose girder, after aliging with nose girder to girder, make spanning take a seat, complete the erection of bridge.Remove receipts
Operation routine is in contrast.Spanning is first risen, is propped up on the rock and roll bearing of two sides, nose girder is fixed with opposite bank rock and roll bearing, led
Draw girder and retract my bank to precalculated position.Release the fixation of nose girder and opposite bank rock and roll bearing, locking nose girder and girder.By girder with
Nose girder retracts together my bank, and to structural focus my bank rock and roll bearing rear is returned to, and releases the locking between nose girder and girder, retracts
Nose girder removes crossbeam to aliging with girder, and girder and nose girder are decomposed into into preassembled unit, remove harvest it is complete.
