Abstract
Provided is a connecting method for steel-concrete composite beam segments. The method comprises: after fully filling epoxy resin in seams between a concrete bridge deck of a formed beam segment and a concrete bridge deck of a hoisting beam segment, connecting through prestressing force, and connecting a steel beam of the formed beam segment and a steel beam of the hoisting beam segment. The connecting method for steel-concrete composite beam segments uses a dry splicing connection, that is, a concrete post-cast section is not arranged between the beam segments, and concrete maintenance is not needed. The steel-concrete composite beam segments are connected through coating the epoxy resin glue on end faces of matched prefabricated bridge decks and maintaining certain pressure reserve.
Description
Technical field
The present invention relates to the method for attachment between the beam section of a kind of bridge site scene girder frame, relate more specifically to
A kind of method of attachment between steel-mixed combination beam beam section.
Background technology
Steel-mixed combinative structure is by giving full play to the material behavior of steel and concrete, it is shown that very well
Stress performance and serviceability, obtained more and more extensive in building and the science of bridge building field of China
Application.
For the combination beam of multi-segmental is constructed, the cast-in-place wet seam of many employings between concrete slab
Connected mode.Wet joint concrete easily participates in stress in low age state, has concrete quality relatively
Big impact, additionally to there is age poor for prefabricated bridge and wet joint concrete, and age difference is the biggest because of contraction
The modified difference caused is the biggest, easily ftractures at faying face, affects structure durability;In consideration of it, manifold
Cross and use expansive concrete to reach the purpose that prevents crack from occurring, but the most domestic extender brand
More, using effect is uneven, lacks detailed specification and instructs, and unit in charge of construction is to expansive concrete
Application lack experience, cause final implementation result not good enough.Additionally, carry out according to demand of technical standard
Wet joint concrete maintenance, then speed of application can be restricted, and especially coastal area is by typhoon influence
Serious bridge construction.
Summary of the invention
It is an object of the invention to provide the method for attachment of a kind of steel-mixed combination beam beam section, known to improve
Defect present in technology.
For achieving the above object, the method for attachment of the steel that the present invention provides-mixed combination beam beam section, be
The seam crossing between the concrete slab of beam section and the concrete slab of lifting beam section has been become to fill up
It is attached by prestressing force after epoxy resin, has become between the girder steel of beam section and the girder steel of lifting beam section
It is attached.
The method of attachment of described steel-mixed combination beam beam section, wherein, has become the concrete slab of beam section
With the seam end face between the concrete slab of lifting beam section is provided with concavo-convex coupling shear connector.
The method of attachment of described steel-mixed combination beam beam section, wherein, has become girder steel and the hoisting beam of beam section
It is to be attached by welding or bolt between the girder steel of section.
The method of attachment of described steel-mixed combination beam beam section, wherein, has become girder steel and the hoisting beam of beam section
After the girder steel of section connects, this beam section prestressing with bond steel bundle of stretch-draw.
The method of attachment of described steel-mixed combination beam beam section, wherein, lifting beam section by guider with
Beam section has been become to correct and position.
The method of attachment of described steel-mixed combination beam beam section, wherein, at the concrete bridge deck becoming beam section
When seam crossing between the concrete slab of plate and lifting beam section fills up epoxy resin, between stretch-draw sections
Interim prestressing force makes seam crossing epoxy resin cure.
The method of attachment of the steel that the present invention provides-mixed combination beam beam section, uses " dry spelling " and connects
I.e. it is not provided with the section of watering after concrete between beam section, it is not necessary to carry out concrete curing, by prefabricated in coupling
Floorings end face smear epoxide-resin glue and keep certain reservation for pressure to be attached.
Accompanying drawing explanation
Fig. 1 is the connection diagram of the present invention.
Fig. 2 is the Fig. 1 sectional schematic diagram along line A-A.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
As it is shown in figure 1, becoming the side of beam section A for lifting beam section B, becoming beam section A
The seam crossing C full coat epoxy of two end faces of concrete slab of concrete slab and lifting beam section B
Resin.Becoming concrete slab and the concrete slab two of lifting beam section B of beam section A
End face is provided with concavo-convex coupling shear connector D (incorporated by reference to Fig. 2), uses short line casting coupling prefabricated, can press
The plane being perpendicular to end face carries out prefabricated so that constructing.First girder steel is referred to according to monitoring during preassembling
Make linear carry out pre-splicing, then mounting bridge panel, two half block floorings conducts that above-mentioned coupling is prefabricated
Entirety is put across sewing cloth, and adapts to angle between beam section by the height gap between two ends and girder steel top board.Peace
Can carry out beam section rectification and location by guider during dress, between stretch-draw sections, interim prestressing force, makes to connect
Epoxy resin cure at seam.Become and connected between the steel beam web plate G of beam section A girder steel and lifting beam section B
(weld or bolt), is becoming concrete slab and the concrete bridge of lifting beam section B of beam section A
The piece both sides of panel are provided with prestressing force tooth bank F, stretch-draw this beam section prestressing with bond steel bundle E, logical
Cross the reservation for pressure that the piece after stretch-draw prestressing force makes gluing keeps certain.
The floorings prestressing with bond pipeline of the present invention uses rustless steel muff joint even in piece position
Connect or rubber ring seal, it is ensured that the durability of prestress system.
Become and be provided with guider on the steel beam web plate of beam section A and the steel beam web plate of lifting beam section B,
Can choose whether to have assisted beam section to install by guider.
Guider in above-described embodiment, prestressing force tooth bank, rustless steel muff joint etc. are known
Technology, no further details to be given herein for the present invention, does not the most recommend accompanying drawing.
The method of attachment installation procedure of the present invention is few, saves edge joint position assembling reinforcement, casting concrete
And curing time, it is possible to it is effectively improved main beam supporting speed at bridge location, shortens the aerial work time, fall
Low construction risk, waters joint concrete issuable disease hidden danger simultaneously, has good after avoiding
Good economic benefit and social benefit;Concrete slab is completed by prefabricated, and its quality can obtain
Effectively control;Being proved by test, the girder continuous slab-deck that the connected mode of the present invention completes is preferable,
There is good road-ability.
The method of attachment of the present invention is applicable to the connection between steel-mixed combination beam beam section, and girder steel part is applicable
In opening or section of remaining silent, and it is applicable to girder steel welding or splice plate bolt.
