Description
Technical field
The utility model relates to restressed beam slab technical field of construction, and construction cost, energy can be saved by referring in particular to one kind
Enough guarantee the restressed beam slab anchor ring pressure maintaining closure assembly of slurry tightness in duct at anchor plate place.
Background technique
Currently, existing method is will with plain condensate mud (or leak stopping king) during restressed beam slab mortar depositing construction
The closing of anchor end steel strand wires, starts after cement slurry reaches some strength to restressed beam slab hole path pressure grouting.Existing prestressed girder
Plate has the disadvantage that have ignored the slurries meeting small part in prestress pipe slip casting stitches from the steel strand wires at anchorage position (anchor end)
It is squeezed out in gap and damages closed anchor end cement lumps, the slurry in anchor plate root position duct often exists after molding
Leakiness phenomenon, and also need to carry out secondary sealing off and covering anchorage, leads to that mud jacking compactness is not good enough and steel strand wires stress transfer is bad, influences prefabricated
Beam construction quality, sealing off and covering anchorage causes construction cost to increase again.
Therefore, construction cost can be saved by designing one kind, can guarantee at where anchor plate slurry tightness in duct
Restressed beam slab anchor ring pressure maintaining closure assembly, just seems very necessary.
Utility model content
The utility model is the anchor plate root position hole after existing prestressed girder sheet metal forming in order to overcome in the prior art
There is leakiness phenomenon and also need to carry out secondary sealing off and covering anchorage in the slurry in road, construction cost, energy can be saved by providing one kind
Enough guarantee the restressed beam slab anchor ring pressure maintaining closure assembly of slurry tightness in duct at anchor plate place.
To achieve the above object, the utility model uses following technical scheme:
A kind of restressed beam slab anchor ring pressure maintaining closure assembly, including anchor plate and cover；The open end of the cover is connected with
Sealing shirt rim, the sealing shirt rim are equipped with N number of bolt hole that can be aligned correspondingly with N number of threaded hole on anchor plate,
Injected hole, N >=3 are additionally provided on the anchor plate.
In the utility model, cover is covered on anchor ring and by bolt cover is fixed together with anchor plate, it is close
Envelope skirt is equally also sealed connected together with anchor plate, then with Grouting Pipe toward the injected hole slip casting on anchor plate.This is practical new
Type has and can save construction cost, can guarantee at where anchor plate in duct the characteristics of slurry tightness.
Preferably, the cover closed end is equipped with air hole, air hole inner wall is in shape of threads.During slip casting,
When there are slurries to start to overflow in air hole, air hole is blocked using plug matched with air hole and continues slip casting.
Preferably, the cover includes columnar side wall and circular bottom plate, the bottom plate and the sidewall weld
Together.Make to connect in the way of welding it is stronger, it is easy to make.
Preferably, the sealing shirt rim of the cover open end connection is in a ring, one of top of the sealing shirt rim
Notch is equipped at angle.The sealing shirt rim of the shape is convenient for being mounted and dismounted with restressed beam slab.
Preferably, it is circular protrusion that the anchor plate, which is equipped with cross section, the injected hole is located at raised brim.On
It states design and facilitates carry out grouting operation.
Preferably, the cover welds together with the sealing shirt rim.Make connection more firm in the way of welding
Gu easy to make.
Preferably, the circle of open end edge one of the cover is equipped with the groove of annular.Groove inner casing is for being arranged elasticity
Sealing ring, for reinforcing the sealed connection effect between cover and anchor plate.
Therefore, the utility model has the following beneficial effects: (1) can effectively solve anchor plate root position duct slurry not
Densification phenomenon can guarantee at where anchor plate slurry tightness in duct；(2) precast prestressed beam slab construction matter is improved
Amount, has saved construction cost.
Detailed description of the invention

Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing:
A kind of embodiment: restressed beam slab anchor ring pressure maintaining closure assembly as depicted in figs. 1 and 2, characterized in that including anchor pad
Plate 1 and cover 2；The open end of the cover is connected with sealing shirt rim 3, and the sealing shirt rim is equipped with 3 can be correspondingly
With the bolt hole 4 of 3 threaded holes 9 alignment on anchor plate, injected hole 5 is additionally provided on the anchor plate.
The cover closed end is equipped with air hole 6, and air hole inner wall is in shape of threads.During slip casting, work as air hole
In have slurries start overflow when, air hole is blocked using plug matched with air hole and continues slip casting.In air hole
Wall is in shape of threads, more convenient when for making to dismantle installed plug.Cover includes columnar side wall and circular bottom plate, described
Bottom plate is together with the sidewall weld.Make to connect in the way of welding it is stronger, it is easy to make.
In addition, the sealing shirt rim of cover open end connection is in a ring, one of vertex of the sealing shirt rim is equipped with
Notch.The sealing shirt rim of the shape is convenient for being mounted and dismounted with restressed beam slab.Cover is welded with the sealing shirt rim
Together.Make to connect in the way of welding it is stronger, it is easy to make.
