Description
Technical field
The utility model belongs to packaged type bridges technical field, specially bridge prefabrication performance of concrete column confined and bridge foundation tooth
Key bell and spigot frame.
Background technique
Bridge prefabrication pier stud with the connection of cushion cap or Extended chemotherapy mainly has steel strand wires to connect at present, grout sleeve reinforcing bar connects
It connects, the bellows that is in the milk connection, cast-in-place wet joint connects and the forms such as bayonet joint.Wherein steel strand wires connection is chiefly used in pier stud point
Prefabricated situation is saved, pier stud segment is concatenated by prestressing force；The connection of grout sleeve reinforcing bar is to connect foot stall steel using grout sleeve
Muscle, connection sleeve is prefabricated inside performance of concrete column confined, is in the milk to form connection by sleeve；Bellows connection of being in the milk is in prefabricated pier
Reserved steel bar on column reserves bellows reinforced hole on cushion cap, and reserved steel bar is inserted into reserved steel bar hole when construction and carries out hole
Road grouting, forms connection, its essence is pier stud reinforcing bars to anchor in cushion cap；Cast-in-place wet joint be connected on the bridge of coastal waters using than
More, in Precast Pier Columns lower end, reserved one section of Cast-in-Situ Segment and cushion cap casting are integrated and form connection；Bayonet joint is to hold
Slot is reserved on platform, Precast Pier Columns are installed in slot, the gap concrete cast-in-situ between Precast Pier Columns and slot, the company of being formed
It connects.
Wherein, the connection of grout sleeve reinforcing bar connects domestic at present only widely apply in low earthquake region, in height with grouting bellows
The application in earthquake region need further to verify.Foreign countries have related data to show, in high intensity Zone it is not recommended that using grouting set
Cylinder connection.No matter and grout sleeve or the bellows that is in the milk connection, when construction, are both needed to the full face reinforcing bar insertion of pier stud is reserved
Duct, and be hole-specifically in the milk, difficulty of construction is larger.
In above-mentioned existing connection type, the application time of cast-in-place wet joint connection and bayonet joint is more long, still
Both each have certain limitation: cast-in-place wet joint method is very high to the requirement of pier stud hanging device, and pier stud lower section is existing
Pouring concrete amount is also bigger；Bayonet joint generally requires cushion cap socket depth not less than 2 times or so of pier stud diameter, in this way
The thickness of cushion cap is required to increased.
Patent No. CN201510967124 it is entitled " bridge prefabrication pier column and cushion cap socket type connecting structure and its
In the patent of assembling method ", a kind of socket type connecting structure is disclosed, the gap between pier stud and cushion cap slot is generally 2cm
Or so, grouting material mud jacking is used in gap, the small alligator of the multiple depth directions of setting in gap.However, under the action of seismic force,
Since multiple alligator distribution of force are uneven, easily cause uppermost small alligator to be initially formed destruction, shear gradually move down later, it is small
Alligator is broken up one by one.On the other hand, since its gap is smaller, easily there is cavity after mud jacking or grouting, it cannot be guaranteed that slurry is full
Full, i.e., the compactness of grouting material is relatively difficult to guarantee in gap, and compactness inspection is also more difficult.Due to the seam between pier stud and cushion cap slot
Gap is small, can not the slip casting directly above gap, need to open up mud jacking channel on cushion cap, shadow will necessarily be caused to cushion cap intensity
It rings, and mud jacking operating efficiency is low.
Summary of the invention
In order to overcome the above technical defects and insufficient, the utility model provides a kind of bridge prefabrication performance of concrete column confined and bridge
It is difficult to solve the multiple alligator distribution of force unevenness of existing alligator bell and spigot frame, the compactness of grouting material for beam basis alligator bell and spigot frame
The technical issues of with guarantee, slip casting low efficiency.
