Description
Technical field the present invention relates to integrate section frame building method for steel truss
Background technology is along with China's rapid economic development, needs the project of building increasing, is the needs that adapt to the China railways great-leap-forward development, the compression duration, just requires steel truss girder to set up must to employ new technology, new technology the target that could realize shifting to an earlier date the duration.
Present steel truss girder sets up the diffusing method of piecing together of general employing to carry out, and the construction period is longer, carries out the whole sections of steel truss girder and sets up research, is intended to develop China's steel truss girder and sets up worker's method, improves modern bridge construction technical level, satisfies construction period requirement and quality requirement.
Summary of the invention the objective of the invention is to aim to provide a kind of quick construction at above-mentioned present situation, sets up reliable quality steel truss girder erection method.
The steel truss girder internode that whole sections sets up is by last lower chord, and brace, montant, railway be beam and flat connection, highway Orthotropic Steel Bridge Deck and interim rod member composition in length and breadth.
Steel truss girder becomes whole sections at producer's processing spelling, and the back water transport of going to river is set up by the direct lifting of girder erection crane to on-the-spot.
1, whole sections girder steel is pieced together the field in advance
Whole sections girder steel is pieced together the field in advance and is arranged in the producer.If the whole internode assembly unit of steel truss girder line, orthotropic plate spelling district and sections girder steel storage area.After rod member processes, be transported on the assembly unit line, be combined into whole sections, to bridge, treat frame by the harbour shipping of going to river.
2, the diffusing sections steel truss girder of piecing together of Dun Ding sets up
Four internodes in main pier top are to set up on support, adopt and hang the diffusing assembly of ship, loose and piece together rod member before appearance, must piece together in advance with whole sections girder steel rod member.The orthotropic plate of piecing together internode that looses is processed into smallclothes in producer, and assembled on site is set up after becoming big part again.
3, whole sections sets up
After four internodes in main pier top were installed, the assembly unit girder erection crane set up to bilateral symmetry from main pier respectively.Full-bridge is only at main Dun Ding, the auxiliary pier top, the abutment pier top, and in stride and close up a mouthful place and establish a spot of diffusing assembly sections, all the other internodes all adopt whole sections erection technique to finish steel truss girder and set up.
It is that sections is sling the back assembly unit on the trusses that frame is good that whole sections is installed, those frame trusses relative position fix and have very big rigidity.Treat that the beam section of frame hangs ampere-hour, if it is identical with the space geometry position of each corresponding assembly unit of frame trusses or junction, whole sections is butt joint with it very smoothly just, therefore requires whole sections to be combined into the geometrical relationship of the geometry states of back in hanging peace should be with assembly unit on pedestal the time and remains unchanged.Because the docking point position for the treatment of of the trusses end of having put up is (as amount of deflection, the corner etc.) that change, and each beam section weight, position of centre of gravity for the treatment of frame are also different, in order to realize mutual butt joint, its opposite position just must be complied with and be coordinated, thus the position of beam section should by loop wheel machine and suspender to sections vertically, laterally, corner, laterally position such as torsional angle is adjusted.
4, the precision of section assembling control
(1) precision of raising factory section assembling
Most important precision control should be placed on the splice point of 6 chord members during factory whole section assembling, must be also tighter than the deviation that standard allows to the control of basic geometric relationship such as purlin height, the purlin of bridge center line, main truss be wide.To design basic physical dimension as benchmark, its plane, elevation position all will place under the high-precision control net and measure.
(2) carry out every measurement of factory's section assembling
Adopt the short-term method to carry out steel truss girder sections spelling, untie by sections then and form independently steel truss girder internode, should carry out the plane and the height measurement at each control point of steel truss girder internode.Factory's domestic demand is put in order the installation test of sections lifting spelling lifting spelling.Also must carry out repetition measurement after the sections lifting, observe its distortion situation and change comparing with the relative position of sections each measuring point on pedestal to each measuring point.If it is too big that these numerical value differ, should analyze reason and take Corresponding Countermeasures, otherwise can not dispatch from the factory, this is operated in factory's section assembling initial stage that begins and just should solves.
(3) main points of whole section assembling on the bridge
What contact assembled beam section the earliest behind the 1. whole section assembling is brace, and brace is inserted in the gusset plate, and this moment, sections was restrained in the lateral attitude, make brace insert gusset plate difficulty does not take place, and key is to control the main truss spacing;
2. the butt joint of chord member can be docked lower chord earlier, docks upper chord again, at last brace is linked to each other with gusset plate.Can change the favourable opposition nail again into earlier with the little nail via hole that dashes during butt joint.
The interior scab of chord member should be fastened band in theoretical position, and does not clamp with rod member.Outer scab is fastened band on chord member or fasten extension thereon, and interior scab forms interior " sleeve " form, and is again that outer scab is in place after interior scab is inserted in the box-shaped rod member, beats and dashes nail and go up, twist high bolt;
3. dash nail quantity and just twist high bolt quantity and determined according to squeezing into, loop wheel machine is loose hook when;
4. in time measure the geometric position that new sections is installed the back beam-ends, after the loop wheel machine traveling, survey the displacement of beam-ends again.By the suspension centre micromatic setting of girder erection crane, adjust the distortion of whole sections steel truss girder and frame steel truss girder distortion coordination mutually.
5, construction sequence;
(1) main pier pier-side bracket is installed;
(2) utilize crane barge waterborne to install between the pier epimerite;
(3) install between the pier epimerite after, between the pier epimerite, girder erection crane is installed;
(4) bilateral symmetry lifting, the whole sections steel truss girder of installation are finished fastening of steel truss girder and are connect and weld;
(5) also stretch-draw suspension cable is installed;
(6) continue to install steel truss girder, installation and stretch-draw suspension cable;
(7) utilizing other loop wheel machines to loose at place, pier position pieces together between installation pier epimerite.
(8) steel truss girder closes up installation.
The present invention is skillfully constructed, quick construction, and its main feature is:
(1) whole sections is easy to guarantee the steel truss girder installation quality at factory's spelling;
(2) whole segment lifting spelling can effectively improve work efficiency, the quickening progress;
(3) reduce on-the-spot bridge floor welding job amount, be easy to guarantee the steel truss girder welding quality;
(4) reduce steel truss girder work high above the ground engineering amount, reduce the danger of work high above the ground.
