Description
Technical field
The present invention relates to a kind of the construction and build the vault of the steel bow member that arch bridge uses, relate in particular to that a kind of bow member vault closes up and bow member unloads the method and apparatus of frame.
Background technology
The steel bow member is to have rack construction to build the indispensable supplementary structure of arch bridge, and steel bow member vault plays crucial effect as the closure segment of assembly unit bow member.Unsettled steel bow member mainly contains two kinds of forms in the prior art bridge arch ring cast-in-place construction: a kind of three slotted-angle shelving assembly unit steel bow members, a kind of tool thunder frame assembly unit steel bow member, these two kinds of forms all do not have the special-purpose device that closes up, can not adjust the internal force and the arch axis line of bow member when closing up, make arch axis line and design that certain error be arranged, influence the mechanical characteristic of bow member, do not have the good rack device that unloads simultaneously again, cause that bow member splits out difficulty, efficient is low, labour intensity is big, influence arch ring quality and construction speed.The prior art bow member unloads to set up and is equipped with adopt " sand tubes " more, and this simple in equipment can not be used for eliminating concrete shrinkage, creep and the internal force of elastic compression, be provided with and use not too convenient, can only be as the rack device that unloads of simple function.
Summary of the invention
The object of the present invention is to provide a kind of steel bow member to close up and unload rack device, vault as the steel bow member when arch bridge is built in construction can play regulating action, execute internal force and the arch axis line that horizontal force is regulated bow member at the upper and lower string of vault when closing up, stride footpath and landform to the requirement of arch ring to satisfy difference, bow member stressedly more is tending towards rationally, evenly, treat that bricklaying reaches when needing after certain intensity folding to remove bow member as unloading rack device, can adjust arch internal force and can split out the steel bow member easily and safely again.
The present invention includes vault sections, jack, adjusting rod, regulate backing plate, vault sections of the present invention is made of upper chord, lower chord, vertical rod, cross bar, web member, be frame construction, the outside is provided with joint connecting screw rod anchor plate in upper chord and the lower chord two ends, one end of upper chord and lower chord is provided with cloudy end circular arc joint, and the upper chord and the lower chord other end are the adjustable side, and its inboard is provided with side plate, jack pad, adjusting backing plate block; Adjusting rod one end of the present invention is an oedoeagus circular arc joint.
When the steel bow member closes up, the oedoeagus circular arc joint of the moon end circular arc joint of the upper and lower chord member of vault sections one side of the present invention and the upper and lower chord member of basic sections of steel bow member joins, bear the pressure that chord member produces, connect by joint connecting bolt (or studs) outward, connecting bolt bears pulling force, at opposite side is the adjustable side, regulates bow member alignment error and bow member internal force with jack by adjusting rod; The reusable connector connecting bolt connects: jack is placed in the chord member of chord member adjustable side between the chord member and side plate, to connect at the bottom of the jack on the jack pad that is provided with on the chord member, put into adjusting rod again, jack piston promotes adjusting rod and advances, in the moon end nose circle joint of the chord member of the basic sections of adjusting rod oedoeagus circular arc joint insertion steel bow member, pushing tow along with piston, the adjusting rod pressurized, form cavity between adjusting rod reach and the adjusting backing plate block, can insert between adjusting backing plate block and the adjusting rod regulating backing plate, regulate bow member alignment error and bow member internal force, use the joint connecting bolt at last, pass the connection anchor plate and connect, finish the bow member assembly unit of arch bridge arch ring.
Bow member is during bricklaying irritate to be built, and the total weight of supporting arch ring treats that bricklaying reaches dismountable bow member after certain intensity, the present invention land bow member can with adjust internal force and carry out simultaneously, eliminate concrete shrinkage, creep and the internal force of elastic compression.When unloading frame to jack applied thrust slowly, when the force value of jack reaches required thrust and keeps period of oil pressure, can eliminate the concrete influence of creeping, reach the purpose of adjusting arch thrust, because the jack application of force, connecting bolt is easy to unload, take out and regulate backing plate, make bow member and cast-in-place arch ring break away from arch striking, the easy removal of bow member.
The present invention is simple, and is easy to operate, and the steelframe rigidity of institute's assembly unit is big, and good stability can effectively be regulated arch ring alignment error and bow member internal force, can adjust arch internal force during unloading frame, improves the arch ring quality, and it is safe and efficient to unload frame.
