Description
Technical field
The invention belongs to railway or highway bridge construction instrument, particularly a kind of in steel truss girder installation process or correct the instrument of its plan-position deviation after the beam that falls, specifically a kind of steel truss girder is in length and breadth to adjusting device in place.
Background technology
Steel truss girder is in installation process and falling after beam, may occur that the deviation of plan-position and design attitude exceeds the situation of standard and test standard requirement, now, must on pier, utilize transverse shifting and vertically move facility steel truss girder is carried out transverse shifting in a small amount and vertically moved, make steel truss girder in place correct.Transverse shifting, vertically move facility and generally include sliding way, glide path, roller bearing or polytetrafluoroethylene (PTFE) slide plate, vertical jack and level jack.Upper and lower slideway is conventionally by crisscross stacked the forming of bloom, rail or i iron, lack of standardization in practice of construction, disunity; And transverse shifting and to vertically move facility be two cover facilities; The steel truss girder of field by using is longitudinal and transverse moves facility or heavy or cause rejection and waste because of oversize cannot use; Because construction experience and the technical level of construction technical staff there are differences,, there is very big potential safety hazard in random stacking slide track materials often at the construction field (site).
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of steel truss girder of simple in structure, with low cost, easy operating in length and breadth to adjusting device in place.This adjusting device can either, for steel truss girder transverse shifting, also can be used in steel truss girder and vertically move.
It is as follows that the present invention solves the problems of the technologies described above the technical scheme of taking: a kind of steel truss girder is in length and breadth to adjusting device in place, comprise glide path, sliding way, vertical jack and level jack, it is characterized in that: above glide path, one end is fixed with rear parados, the other end is fixed with block, above glide path, be fixed with polytetrafluoroethylene (PTFE) slide plate, above polytetrafluoroethylene (PTFE) slide plate, slidingtype is installed slideway, vertical jack is installed above sliding way, between rear parados and sliding way, level jack is installed.
Glide path comprises glide path base plate, glide path top board and two blocks of glide path side plates, and glide path base plate, glide path top board and two blocks of side plates of glide path enclose composition casing, fixedly mounts side by side three～five one steel rails in casing.
The structure of sliding way and glide path is basic identical.Sliding way comprises sliding way base plate, sliding way top board and two blocks of sliding way side plates, and sliding way base plate, sliding way top board and two blocks of side plates of sliding way enclose composition casing, and fixed installation three～five one steel rails side by side in casing are provided with corrosion resistant plate below sliding way base plate.
Vertical jack is for jacking steel truss girder: according to steel truss girder, from re-computation support reaction, and select vertical jack tonnage, vertical jack is placed under end node backing plate; Be arranged on level jack between sliding way and rear parados for mobile sliding way: level jack piston immediate roof is lived in slideway right-hand member or left end head, promote sliding way and move, and then Mobile steel trusses.Confficient of static friction between polytetrafluoroethylene (PTFE) slide plate and corrosion resistant plate is by not adding silicone grease value μ
f=0.10, according to steel truss girder total weight, promote the frictional force that steel truss girder moves, and then select level jack tonnage.
It is roughly as follows that application the present invention moves the beam course of work:
One, laterally move beam: the bolt of (1) traversing front whole hole steel truss girder should be twisted complete entirely eventually, makes steel truss girder have sufficient lateral stiffness, in case produce bending;
(2) move Liang Shixian and start vertical jack, jack-up steel truss girder 1-2cm, comes to nothing the bearing under steel truss girder and node completely.In the same time, only allow a fulcrum to carry out lifting operation, two of the left and right fulcrum on same pier should hocket, and completes one by one;
(3) start level jack and laterally move beam.Before starting, should carefully check that slide plate is laid situation and there is clear etc. at fulcrum place.For observing traversing distance, can, with the plumb bob that hangs over crossbeam mid point, read at any time the offset distance with bridge pier center;
(4), during traversing putting in place, should slow down, accurate adjustment position.
Two, longitudinally move beam: assembled, complete and after traversing adjustment, can carry out vertical shift.During vertical shift, each fulcrum is all established vertical shift facility, and vertical shift facility is identical with traversing facility, as long as traversing facility is horizontally rotated to 90 °, can use;
(1) traversing end falls beam after temporary support, in the back timber position of the left and right symmetry of end floor beam, install a buttress and steel cushion block and roof fall beam jack, remove again traversing facility and horizontally rotate after 90 °, longitudinally be arranged under end node symmetrically, enable the roof fall beam facility under end floor beam, steel truss girder is fallen within on vertical shift facility, pressurized rear left and right vertical shift facility has different sinking, should enable again cushioning after jack jacking, the left and right two main truss discrepancy in elevation are controlled in 2mm, and the roof fall beam facility under while end floor beam and temporary support and steel truss girder come to nothing in 2cm.
(2) check and determine that whole hole steel truss girder vertically moves after obstacle without any, start level jack, slowly steel truss girder is moved to design attitude in top; The in parallel assurance synchronously of level jack oil circuit arranging on fulcrum, synchronously stressed to guarantee every fulcrum.
The present invention provides a kind of new tool for correcting its plan-position deviation in steel truss girder installation process or after the beam that falls, and the advantages such as making is simple, with low cost, easy operating that it has, are convenient to promote the use of; Especially the present invention uses same set of facility for laterally moving beam and longitudinally moving beam, in other words; The present invention both can be used for laterally moving beam and also can be used for longitudinally moving beam; Traversing facility is horizontally rotated to 90 ° and can be used as vertical shift facility.
