Preferably, in described concrete column diameter of a circle less than/equal to two points of outer regular hexagon inscribed circle diameter One of.

Preferably, described first annular stirrup, the second annular stirrup and the circle of the 3rd annular stirrup Ring thickness is 2-3 centimetre.

Preferably, outside described first annular stirrup, the second annular stirrup and the 3rd annular stirrup Circular diameter is 3/4ths of outer regular hexagon inscribed circle diameter, and the diameter of described concrete column inner circular is equal to outer positive six limits / 2nd of shape inscribed circle diameter.

Preferably, described at least one piece of reinforced slab be arranged on outside described concrete column upper end orthohexagonal relatively On the tangent plane connecting diagonal formation connecting diagonal orthohexagonal opposed apexes outer with opposing lower end on summit.

Preferably, 1/2nd of described reinforced slab width are arranged on concrete column hollow parts.

Preferably, the thickness of described reinforced slab is 2-3 centimetre.

Preferably, the external orthohexagonal opposed apexes diagonal of described concrete column is 40-80 centimetre.

Beneficial effects of the present invention is as follows:

The concrete-pile of the present invention is outer regular hexagon inner circular hollow cylinder, and outer regular hexagon can dramatically increase concrete Stake and the frictional force of the soil body, combine with the steel reinforcement framework cage in concrete-pile body, significantly improve the load-bearing energy of concrete-pile Power；Steel reinforcement framework cage half is placed in concrete-pile body, and half is placed in concrete-pile hollow cylinder, by steel reinforcement framework cage Reinforced slab add frictional force and the cohesive force of concrete-pile and the soil body, significantly improve the resistance to plucking core ability of concrete-pile, carry The safety of high building construction, and the consumption of effectively save reinforcing bar, reduce building cost.

Detailed description of the invention

The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to description literary composition Word can be implemented according to this.

As Figure 1-3, a kind of concrete-pile 1, including concrete column 2, steel reinforcement framework cage 3, concrete column 2 is outward Regular hexagon inner circular hollow cylinder, outer hexagonal cylinder can increase the frictional force of cylinder itself, the energy when inserting in the soil body Dramatically increase the frictional force of cylinder and the soil body, be effectively improved withdrawal resistance；Steel reinforcement framework cage 3 includes reinforced slab the 31, first annular Stirrup the 32, second annular stirrup the 33, the 3rd annular stirrup 34；First annular stirrup the 32, second annular Stirrup 33 is identical with the 3rd annular stirrup 34 shape size, and thickness is 2-3 centimetre, the first annular stirrup 32, Outside diameter is outer regular hexagon inscribed circle diameter the four of two annular stirrups 33 and the 3rd annular stirrup 34/ Three, the diameter of concrete column inner circular is equal to 1/2nd of outer regular hexagon inscribed circle diameter, and annular stirrup is arranged In concrete column body, it is effectively improved the weight capacity of concrete-pile；Reinforced slab 31 is rectangle, reinforced slab length and concrete Cylinder 2 is contour, and reinforced slab 31 at least 6 pieces can improve the frictional force of cylinder hollow parts, and the upper end on the long limit of reinforced slab 31 is by weldering Connecing and be fixedly connected on the first annular stirrup 32 inwall, the middle part on the long limit of reinforced slab 31 is fixedly connected by welding second On annular stirrup 33 inwall, the lower end on the long limit of reinforced slab 31 is fixedly connected by welding in the 3rd annular stirrup 34 On wall, first annular stirrup the 32, second annular stirrup 33 is parallel with the 3rd annular stirrup 34, forms one admittedly Fixed column structure, significantly increases comprcssive strength and weight capacity, first annulus on steel reinforcement framework cage 3 of framework of steel reinforcement dragon Shape stirrup the 32, second annular stirrup 33 and the 3rd annular stirrup 34 are arranged in concrete column body, reinforced slab 31 Width 1/3 is arranged on concrete column 2 hollow parts；Reinforced slab 31 is arranged on outside described concrete column 2 upper end The connection diagonal connecting diagonal orthohexagonal opposed apexes outer with opposing lower end of orthohexagonal opposed apexes is formed Tangent plane on；/ 2nd of reinforced slab 31 width are arranged on concrete column 2 hollow parts；The thickness of the reinforced slab 31 used Being 2 centimetres, the outer orthohexagonal opposed apexes diagonal of concrete column 2 is 40 centimetres.
