Abstract
The utility model belongs to the technical field of bridge engineering, particularly, relate to an assembled T beam bridge hogging moment district anchorage sealing system. The anchorage sealing system is including built -in notch, anchorage sealing concrete, crack control reinforcing bar net piece, built -in notch prefabrication is on the T roof beam, steel strand wires one end is passed built -in notch and is buried underground in the T roof beam, and another pot head has anchor clamps and fixed with the ground tackle, be equipped with crack control reinforcing bar net piece in the built -in notch to fill the anchorage sealing concrete. Compared with the prior art, assembled T beam bridge hogging moment district anchorage sealing system built -in through making the anchorage sealing district, remove processes such as the template is strutted, the ligature of crack control reinforcing bar net piece from, improved anchorage sealing concrete pouring quality when reducing to construct the process, practice thrift construction cost.
Description
Technical field
This utility model belongs to technical field of bridge engineering, it particularly relates to a kind of fabricated T beam bridge hogging moment area envelope
Anchor system.
Background technology
As expressway construction is shifted from Plain to mountain area, increasing fabricated T beam bridge obtains engineer applied.Mesh
Front fabricated T beam bridge main beam structure major part is used《Bridges and culverts universal design drawing》In standard drawing, wherein hogging moment steel
What twisted wire anchorage zone adopted is the cast-in-place concrete sealing off and covering anchorage that apparent size is about 400mm × 400mm × 150mm, and the program need to
Hogging moment tooth plate area vertical muscle is exposed into about 100mm when T is beam prefabricated, during so as to cast-in-place sealing off and covering anchorage concrete, fix reinforced mesh；
And surrounding needs template support when sealing off and covering anchorage concrete is poured.From the point of view of long-term Construction practices, this kind of sealing off and covering anchorage method is because of behaviour
Make narrow space, template support, reinforcing bar colligation are difficult, it is difficult to ensure that the quality of sealing off and covering anchorage concrete, and construction cost is higher.
The content of the invention
To solve problem above, this utility model provides a kind of fabricated T beam bridge hogging moment area easy, efficiently, economic
Sealing off and covering anchorage system.
A kind of fabricated T beam bridge hogging moment area sealing off and covering anchorage system described in the utility model, the sealing off and covering anchorage system includes built-in
Notch 1, sealing off and covering anchorage concrete 2, anticracking reinforced mesh 3；The built-in notch 1 is prefabricated on T beams；5 one end of steel strand wires passes through built-in
Notch 1 is simultaneously embedded in T beams, and the other end is cased with fixture and is fixed with anchorage 4；Anticracking reinforced mesh 3 is provided with built-in notch 1,
And fill sealing off and covering anchorage concrete 2.
A kind of fabricated T beam bridge hogging moment area sealing off and covering anchorage system described in the utility model, the anticracking reinforced mesh 3 are parallel
It is located at 1 surface 3cm of built-in notch.
A kind of fabricated T beam bridge hogging moment area sealing off and covering anchorage system described in the utility model, 1 inner space of built-in notch
For inner small and outside big landing shape.
A kind of fabricated T beam bridge hogging moment area sealing off and covering anchorage system described in the utility model, the sealing off and covering anchorage concrete 2 are low stream
Dynamic degree or half stiff pea gravel concreten.
Compared with prior art, fabricated T beam bridge hogging moment area sealing off and covering anchorage system described in the utility model is by making sealing off and covering anchorage
Area is built-in, removes the operations such as template support, anticracking reinforced mesh colligation from, improves sealing off and covering anchorage concrete while reducing working procedure
Pouring quality, saves construction cost.

Specific embodiment
With reference to specific embodiment fabricated T beam bridge hogging moment area sealing off and covering anchorage system described in the utility model is made into
One step is illustrated, but protection domain of the present utility model is not limited to this.
Embodiment 1
A kind of fabricated T beam bridge hogging moment area sealing off and covering anchorage system, including built-in notch 1, sealing off and covering anchorage concrete 2, anticracking bar-mat reinforcement
Piece 3；The built-in notch 1 is jointly prefabricated when T beams make；It is mixed with the sealing off and covering anchorage after steel strand tension, pipeline pneumatic mortar are finished
Solidifying soil 2 closes built-in notch 1.Sealing off and covering anchorage concrete 2 is poured to away from 1 surface 3cm of built-in notch or so Shi An in the built-in notch 1
Anticracking reinforced mesh 3 is put, then proceedes to pour sealing off and covering anchorage concrete 2 to 1 surface of built-in notch, and receipts slurry of wiping one's face.The built-in groove
1 inner space of mouth is inner small and outside big landing shape.The sealing off and covering anchorage concrete 2 is low fluidity or half stiff pea gravel concreten.
By the reinforced mesh 3, prefabrication also live can be processed, during placement and away from 1 surface 3cm of built-in notch or so section surrounding
Hold out against.The built-in notch 1 does not need template support when pouring sealing off and covering anchorage concrete 2.
It is when Liang Chang carries out T beams and makes, common prefabricated together with built-in notch 1,1 inner surface of built-in notch is repaiied after form removal
It is whole, and to 1 inner side dabbing of built-in notch to be well combined with rear pouring concrete.Before the sealing off and covering anchorage of hogging moment area, carefully in cleaning
Put debris in notch 1, and moistening of sprinkling water.Remove 1 inside excessive moisture after-pouring of built-in notch, half stiff microlith sealing off and covering anchorage concrete 2
It is closely knit to away from built-in notch surface about 3cm or so, being plugged and pounded with spatula, then cutting suitable precast reinforced mesh sheet is put into built-in
Notch 1 is simultaneously held out against with surrounding, is continued to pour half stiff microlith sealing off and covering anchorage concrete 2 to notch surface, is plugged and pounded with spatula again closely knit
It is afterwards that surface is floating, and carry out watering health preserving.
