Description
Technical field
The present invention relates to suspension type rail traffic system, in particular to a kind of suspension type monorail Rail Transit System two-wire is pre-
Prestressed concrete track beam construction.
Background technique
Track girder in common suspension type monorail Rail Transit System is the Thin Walled Steel Box Beam of lower opening, and train passes through outstanding
The mode of extension runs on the lower section of track girder, and bogie is located in the box body portion.Track girder provides load-bearing for train and guiding is made
With and being the carrier of tractive power supply system, it collects various engineering and acts on one, therefore technically needs certain strong
Degree, rigidity and stability.
Different from conventional box beam, the primary load of track girder acts on the inside of plate top surface and web, and track girder is not only
Need to meet intensity, rigidity and durability requirements, whole torsional rigidity and lateral stiffness are also most important, not only influence knot
The safety of structure also functions to decisive role to road-ability.
As shown in Fig. 2, track girder generally uses open steel box structure in existing suspension type monorail Rail Transit System,
Main body is welded by left web, right web, top plate, left-side bottom, right side bottom plate, and left web, right web are lateral
Interval is erect and is welded in top board undersurface, and connection left-side bottom, right side bottom plate is respectively welded in left web, right web lower end,
And left-side bottom, right side bottom plate bottom surface on weld longitudinal stiffener, this track girder structural form is able to satisfy use substantially
It is required that but there is the deficiency of following aspect: 1, steel track girder cost is higher.Bifilar suspension formula monorail track beam is every meter average
With 2.4 tons of steel, about 1.7 ten thousand yuan of steel comprehensive unit price per ton, therefore, about every meter 40,000 yuan of conventional track beam cost；2, maintenance is tired
It is difficult.Because bottom plate transverse stiffener quantity is larger, difficulty of processing and the period of entire track girder, and more difficult maintenance are increased；3, row
Vehicle comfort is poor.Because of the steel box-girder that track girder is lower opening, and weld seam is more, the welding deformation generated after entire beam body processing
It is not easy to control, and suspension type monorail is because of its unique " unification of beam rail " characteristic, so that its road-ability relies heavily on track
Beam machining accuracy, meanwhile, steel construction itself also easily vibrates；4, difficulty of construction is larger.Either German pin shaft connection side
The support connection type of formula either Japan, because of the lesser original of pier top connecting portion bulk when setting up or removing track girder
Cause, a general hole beam need 4-6 platform crane while cooperating, and difficulty is larger；5, structures under wind damping property is bad.Suspension type
Single track steel construction track girder generally uses 25m as standard span, clear span about 0.78m in section, clear height about 1.1m, whole knot
The lateral stiffness and torsion stiffness of structure are smaller, and because the damping ratio of steel construction is relatively small, structure easily occur vehicle cause vibration and
Wind-induced vibration, and it is not easy to control.
Summary of the invention
It is mixed that technical problem to be solved by the invention is to provide a kind of suspension type monorail Rail Transit System two-wire prestressing force
Solidifying soil track beam construction reduces the vibration of structure to effectively improve fatigue behaviour, transverse direction and the torsion stiffness of track girder, improves
Road-ability, and it is effectively reduced integrated engineering cost.
The technical solution adopted by the present invention to solve the technical problems is as follows:
Suspension type monorail Rail Transit System two-wire prestressed concrete track girder construction of the invention, it is characterized in that: by
Top plate and bottom plate, left web, right web and endosternum constitute prestressed concrete box girder, in the prestressed concrete box girder
Chamber on the left of being formed between left web and adjacent endosternum forms right side chamber between right web and adjacent endosternum,
Intermediate chamber is formed between left side chamber, right side chamber, the middle part bottom plate of intermediate chamber bottom, which is located at, is set to pier stud top
On the bridge pad at end；Longitudinal elongated left side groove profile is opened up in the left side chamber on the left end bottom plate of its bottom to open
Mouthful, left rail is fixed on the left end plate top surface of the left side slot-type openings two sides；In the right side chamber
Longitudinal elongated right side slot-type openings are opened up on the right-hand end bottom plate of its bottom, right rail is fixed on the right side groove profile
It is open on the right-hand end plate top surface of two sides.
The beneficial effects are mainly reflected as follows following aspects:
One, two siding tracks are set to the left side chamber at prestressed concrete box girder both ends, in the chamber of right side, relative to existing
The steel case track girder for having left and right sides to separate, the prestressed concrete box girder are overall structure, and the entirety for considerably increasing structure is anti-
Curved and torsional rigidity, improves the wind resistance resistance to shock of structure, while simplifying structure construction and working procedure.
Two, directly prestressed concrete box girder is placed on pier top, it is identical as conventional method for bridge construction, can not
Bridge Erector also can be used when constructing using crane to construct, construction efficiency can be increased substantially；
Three, it is that prestressed reinforced concrete structure, construction cost and later maintenance cost and expense are far low that structure, which uses,
In existing steel case track girder.
Four, prestressed concrete box rigidity and damping ratio are larger, resist the property that vehicle causes vibration and wind-induced vibration to structure
It can improve a lot, the raising and reduction noise to road-ability have good result.
