Description
Technical field
The invention belongs to field of bridge construction, and in particular to a kind of chevron shaped prestressed concrete pre-tensioned method Bridge Erector and make
Use method.
Background technology
Modern Traffic net construction mostly uses multilevel traffic, this relates to a large amount of overbridges and overhead bridge construction.This kind of bridge
The characteristics of be multispan, Gao Dun, across footpath is little（Less than 50m）, but by construction red line scope limitation, it is more demanding to construction method,
When being transformed to city road network especially with overpass scheme, restrictive condition is more harsh.Existing highway bridge erection construction side
Method and construction equipment are more, can totally be divided into concrete prefabricated assembly construction and cast-in-place method construction two major classes.Prefabrication and assembly construction is constructed
Component production quality is easy to control, and standardization level is high, and site operation speed is fast, but is limited by transport and is risen and re-mount equipment
It limits, connection is more between component, and beam overall performance is relatively poor；Cast-in-place method construction biggest advantage is that bridge integrity is good, special
It Shi He not continuous bridge and special-shaped non-uniform beam bridge construction.For the construction of Mid and minor spans prestressed concrete continuous beam, often
Include the methods of full framing, beam-type support and mobile formwork with bridging method.First two belongs to fixing bracket construction method, needs
It occupies space under bridge and needs to carry out consolidation process to basis under bridge, working procedure is cumbersome.Mobile formwork method utilizes built
Support of the good bridge lower part bridge pier as mould bases, using steel construction, across pier, mobile formwork, mould bases size are big by cross, walking side
Formula is straight line pushing tow, and prestressed stretch-draw is post stretching, is suitable for the construction of multispan prestressed concrete cross-section, linear type beam bridge.
Invention content
The purpose of the present invention is to provide one kind being not take up space under bridge, can improve the chevron shaped of bridge construction efficiency and pre- answer
The concrete pre-tensioned method Bridge Erector of power and application method.
The technical solution adopted in the present invention is：
A kind of chevron shaped prestressed concrete pre-tensioned method Bridge Erector, including herringbone shaped steel frame, thrustor, top elevator
Machine, i-beam track, track hoist engine, support jack, deformed bar/steel beam, monoblock type bed die；

By said program, the slidably crossbeam is connect with triangle fixing bracket, triangle fixing bracket and I-steel
Track is slidably connected, and triangle fixing bracket is used to ensure the verticality of slidably crossbeam.
In the present invention, original state is：Front leg strut unit, rear support leg unit fall within respectively first across two bridge piers on,
It is located at（Starting）On first row bridge pier and second row bridge pier, filled by the first extension sleeve, the second extension sleeve, pushing tow
It sets, the first top gear, the second top gear, slidably crossbeam adjustment herringbone shaped steel frame position；It is installed using top hoist engine
I-beam track.
The present invention also provides a kind of application methods of chevron shaped prestressed concrete pre-tensioned method Bridge Erector, including walk as follows
Suddenly：
Above-mentioned chevron shaped prestressed concrete pre-tensioned method Bridge Erector is set up, is made on fixing end anchoring piece and first row bridge pier
Built-in fitting connect, make slidably crossbeam be placed on second row bridge pier；
Top hoist engine decentralization wirerope promotes monoblock type bed die to precalculated position；After assembling reinforcement, into monoblock type bed die
When casting concrete forms beam body, the constraint of slow release thrustor, beam body dead weight and monoblock type bed die weight transmitting are to herringbone
At the top of shaped steel frame, the forward horizontal thrust of herringbone shaped steel frame bottom is converted to, makes slidably that crossbeam forward movement, triangle are fixed
Holder ensures the verticality of slidably crossbeam；The tensioning of deformed bar/steel beam is controlled by the displacement distance of slidably crossbeam
Proof stress；After concrete reaches prescribed strength, top hoist engine slow release monoblock type bed die；Beam body weight is by first row
Bridge pier, second row bridge pier are gradually born, and the forward horizontal thrust of herringbone shaped steel frame bottom gradually reduces, and slidably crossbeam gradually returns
Contracting,（Utilize its power）Slough anchor clipper, make slidably crossbeam disconnected with deformed bar/steel beam, so far prestressing force is mixed
The first beam section of solidifying soil completes；
Contacting between the built-in fitting on releasing fixing end anchoring piece and first row bridge pier, using track hoist engine to I-shaped
Steel track applies horizontal pull, and i-beam track drives rear support leg, the first extension sleeve in the first beam section bridge to have completed
Towards front slide；It is fixedly connected with the built-in fitting on second row bridge pier after the first extension sleeve reaches second row bridge pier pier top,
The support jack jack of i-beam track front end falls on third row's bridge pier and supports in place, front leg strut unit suspension simultaneously
In on i-beam track, front leg strut unit forward slip is pushed by thrustor, until reaching third arranges bridge pier pier top；Make pre-
Stress reinforcing bar/steel beam is anchored by anchor clipper and slidably crossbeam；It can carry out the second beam section construction；So continuing cycling through can
Carry out the construction of follow-up each bridge.
The beneficial effects of the present invention are：
This chevron shaped prestressed concrete pre-tensioned method Bridge Erector is simple in structure, and move mode is unique, is suitable for different across footpaths
Prestressed concrete continuous beam（Plate）The pre-tensioning system of bridge is constructed；In work progress, the weight tensioning of concrete and template etc. is utilized
Deformed bar/steel beam has given full play to the characteristics of pre-tensioning system is constructed, has eliminated a large amount of anchorages in post-tensioned construction, avoid
The excessive problem of concentrated stress under anchor, saves the materials such as cracking resistance reinforcing bar under anchor when prestress application, also eliminates multiple under anchor
Miscellaneous cracking resistance construction；Bridge construction is set to become simple, quick；
The horizontal thrust generated under vertical load using chevron shaped structure, for applying prestressing force, at the same time by
The deformed bar of drawing/steel beam is also as the girt for balancing chevron shaped mechanism；
Construction period is small on being influenced under bridge；
The present invention is using the continuous presstressed reinforcing steel arrangement of pre-tensioning system, the characteristics of transmission due to pretensioned prestressing, continuous beam
（Plate）Fulcrum section not will produce tensile stress at top surface so that the bridge formation mechanism has good applicability；
Size of the present invention is small, installs conveniently, mobile flexible, is greatly improved construction efficiency；
The present invention makes full use of chevron shaped design feature, is pretension by casting concrete beam body weight conversion, while pre-
The girt of stress reinforcing bar/chevron shaped structures of steel Shu Zuowei, plays balanced action so that this chevron shaped prestressed concrete is first
