Description
Technical field
The utility model relates to building trades, and in particular to the connection structure of tubular pole and cushion cap.
Background technique
Base for post is usually to be formed by connecting by stake position with cushion cap, and its main function is to provide the foundation location and branch of suspension column
Support, the structural behaviour of base for post decide the connection rigidity and intensity of top suspension column.Therefore, between stake position and cushion cap in construction
Connection should focus on its building performance.Hollow tubular piles of prestressed concrete has many advantages, such as short time limit, low cost, in engineering
In be widely used.But because foundation pile is prefabrication, cushion cap is field cast-in-place, the company between existing foundation pile and cushion cap
Connect, mostly use and fill heart connection, this method often because removing the reasons such as pile foundation inner wall mud is not clean, interfacial agents brushing is uneven,
It causes to fill the heart and pile foundation switching performance is unstable, be unable to satisfy upper load demand, cause to cause basement because of joint fails
The accident of floating happens occasionally.
Utility model content
The purpose of this utility model is to provide the jointing of a kind of resistance to plucking hollow tubular piles of prestressed concrete and cushion cap,
To solve the above technical problems.
The technical issues of the utility model is solved can be realized using following technical scheme:
A kind of jointing of resistance to plucking hollow tubular piles of prestressed concrete and cushion cap including a hollow tubular pole and is supported on
Cushion cap on tubular pole, the tubular pole is interior to be equipped with a steel pallet, and the top of the tubular pole extends to the inside of the cushion cap；
Core, the steel of being advocated are filled out it is characterized in that, being welded with stress main reinforcement in the tubular pole and being perfused with concrete
One end of muscle is welded in the steel pallet, and the other end is pierced by from the top of the tubular pole and extends to the inside of the cushion cap,
Interval is connected with circular stirrup on the stress main reinforcement；
It is welded with connecting plate and additional transverse steel bars on the upper surface of the tubular pole, is welded on the connecting plate additional vertical
To reinforcing bar, the additional longitudinal reinforcement extends to the inside of the cushion cap.
Connecting plate, additional transverse steel bars and additional longitudinal direction are welded at the tubular pole of the utility model and the connecting node of cushion cap
Reinforcing bar increases shearing strength and tensile strength at connecting node, and scientific structure design is reasonable, makes pile foundation most by multiple defence line
It is effective that anti-pulling capacity is provided.Connection type associativity between the two is good simultaneously, durability and fastness are very ideal,
It is suitble to in-site installation production.
The stress main reinforcement is even number root and at least 6, and the stress main reinforcement is parallel to the center of the tubular pole
Axis setting, and be around center equidistantly distributed with the central axis of the tubular pole.
The connecting plate is even numbered blocks and at least 6 pieces, and the connecting plate is arranged along the diametrical direction of the tubular pole, and with
The central axis of the tubular pole is around center equidistantly distributed.
The stress main reinforcement is identical as the quantity of the connecting plate, and position corresponds.
The additional transverse steel bars are welded between opposite two stress main reinforcements and two pieces of connecting plates.
The central axis of the additional longitudinal reinforcement and the tubular pole is at least 15 ° of angles.
If the diameter of the stress main reinforcement is D, the tubular pole extends to the length inside the cushion cap and is not less than 10D,
The stress main reinforcement extends to the length inside the cushion cap not less than 40D, and the length of the additional longitudinal reinforcement is not less than
40D。
