The assembled method erecting steel truss girder of original position, after pier stud construction, carry out steel truss girder assembling putting up platform, set up rack platform exactly under the position of design steel truss girder, on rack platform, then carry out steel truss girder assembled, and the beam that finally falls is in place.
For the rack platform of highway interchange, must ensure to have a good transport and communication network and traffic, construction safety; For river course, must ensure that normal navigation and steel girder member bar transport put in place, so potential safety hazard is larger.And must to carry out steel truss girder assembled after pier stud construction, can not parallel construction, can only sequential analysis, and in operation process, relating to the problem such as traffic and navigation, the engineering time is longer, and needs to set up assembled and dilatory orbital platform, platform support materials are more, costly; Pier stud and steel truss girder are assembled cannot synchronously construct, and the duration is longer.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of structure simple, save material, cost-saving, the duration is short, can eliminate safe hidden trouble, dependable performance, easy to operate, stay-in-grade transportation by driving bridge.
For solving the problem, the utility model adopts following technical scheme: the transportation by driving bridge that a kind of security and stability is high, comprise floating pier, and be arranged on the bracket buttress of Fu Dun upper end, and be arranged on the I40b shaped steel bearing beam of bracket buttress upper end, and be erected at the I55 shaped steel main longitudinal grider of I40b shaped steel bearing beam upper end, and be erected at the falsework for erecting bridge of I55 shaped steel main longitudinal grider upper end, and the sleeper being erected at falsework for erecting bridge upper end props up buttress, and be arranged on both sides and float Liu Siliang on pier.
Further, described bracket buttress is mutually superposed by 5 layers of bracket and is formed.
Further, be also provided with coupling assembling between described six or four beams and floating pier, described coupling assembling comprises the thick steel plate of 16mm, and is arranged on the side of a ship outboard angle below steel plate, and the high-strength bolt of fixing side of a ship outboard angle and steel plate.
The beneficial effects of the utility model are:
1. adopt this transportation by driving bridge to carry out steel truss girder assembled, in main span, set up support draw track as steel truss girder, save material, cost-saving;
2. can with main pier synchronous construction, can the reduction of erection time, save overhead cost;
3. do not close navigation channel and traffic data process, can eliminate safe hidden trouble;
4. the method advanced technology, dependable performance, easy to operate, steady quality, has wide popularizing application prospect.
