Two root canal piles are linked into an integrated entity, are provided with billet between the steel plate of two contacted above and below end, the periphery of billet is at saw
Dentation, the bolt hole of exposed end steel plate.But two root canal piles are connected by screw bolts in joint, bolt small volume, in spiral shell
It is also easy to produce stress concentration at keyhole, causes pile body to destroy when serious；By lifting, transport and the conditions such as pile sinking machinery are limited, single-unit
Preset pile length is little, and long stake needs pile extension, and the weak link of pile body is commonly formed in connector, restricts its load-carrying properties.
Utility model content
Technical problem to be solved by the utility model is to provide a kind of for increasing connecing for pile for prestressed pipe strength of joint
Header structure, it is convenient to construct, and investment is small, using the excellent tension of interpolation type connector, antitorque and compressive property, can effectively improve
The integral strength of pile body junction.
To solve the above-mentioned problems, the technical scheme adopted by the utility model is it is a kind of for increasing pile for prestressed pipe
The joint structure of strength of joint, including it is lower part stake, top stake, top end steel plate, lower part end steel plate, prepared screw-bolt hole, same
Bolt is tightened to spiral, the lower part being integrally formed with lower part pile body is provided between lower part stake and lower part end steel plate and connect
Section is provided with the top linkage section being integrally formed with top pile body, top linkage section between top stake and top end steel plate
It is respectively arranged with rectangular jack with the axial direction of lower part linkage section, the interpolation type connector to match with rectangular jack being separately provided is worn
Billet is crossed, upper and lower ends are just inserted into the rectangular jack of top linkage section and the rectangular jack of lower part linkage section respectively, then lead to
It crosses spiral in the same direction and tightens bolt and connect with prepared screw-bolt hole, lower part stake and top stake is made to link into an integrated entity.
The material of the interpolation type connector is precast concrete square column, strength grade of concrete >=C60.
Side length >=1/3 times pile for prestressed pipe the outer diameter of the interpolation type connector.
The material of the top linkage section and lower part linkage section is precast concrete square column, strength grade of concrete >=C60.
Height >=20cm of the top linkage section and lower part linkage section.
Height >=10cm of top end steel plate and lower part end steel plate.
The utility model has the beneficial effects that the excellent tension of interpolation type connector, antitorque and compressive property, can effectively improve
The integral strength of pile body junction, it is convenient to construct, and invests small.
