A kind of variable cross-section concrete pile joint as above is characterized in that being provided with steel and connects end plate on described connector portions.
In the utility model, the both ends of the surface sectional dimension is different, is the steel plate structure, and the centre is formed by connecting by reinforcing bar, and uses the pouring concrete one; Two different size end faces seamlessly transit, and are prism-frustum-shaped or round table-like; By using the non-uniform pile joint, how make can be combined integrated with the different stake of sectional dimension.
A kind of variable cross-section concrete pile joint as above is characterized in that described joint body is hollow-core construction.
A kind of variable cross-section concrete pile joint as above is characterized in that described joint body is solid construction.
In the utility model, the reinforcing bar of two ends steel connection end plate can carry out arrangement of reinforcement according to a up and down stake mechanical property, and joint mechanical property is not less than mechanical property junior in the stake of up and down; The joint concrete strength is not less than the concrete strength of pile that connects up and down stake.
A kind of variable cross-section concrete pile joint as above is characterized in that the thickness of described steel connection end plate is 10～30mm.The end plate edge leaves same groove with the end plate of up and down pile extension, in order to weld with stake, the joint two end plates makes the up and down two end plates welded by reinforcing bar in joint.
A kind of variable cross-section concrete pile joint as above is characterized in that described connector portions for circular, and wherein the diameter of the circular connecting portion of an end is greater than the diameter of the circular connecting portion of the other end.
A kind of variable cross-section concrete pile joint as above is characterized in that described connector portions is square, and wherein an end square knuckle section is greater than other end square knuckle section.
A kind of variable cross-section concrete pile joint as above is characterized in that described connector portions one end for circular, and the described connector portions other end is square.
A kind of variable cross-section concrete pile joint as above is characterized in that described joint body concrete strength, anti-bending strength and shear behavior are not less than to be connected two concrete respective performances intensity.
A kind of variable cross-section concrete pile joint as above is characterized in that described connector portions is polygon.
In sum, the utility model with respect to its beneficial effect of prior art is:
Non-uniform pile joint of the present utility model, with the conventional piles connected mode always, simple to operate, low cost of manufacture capable of being combinedly goes out multiple stake type and satisfies requirement of engineering.
