Embodiment Construction
[0078] The present invention will be further described below in conjunction with accompanying drawing.
[0079] see Figure 1 to Figure 13 , the assembly structure of the assembled steel pipe recycled concrete pile and reinforced concrete beam of the present invention comprises a steel pipe concrete pile, a reinforced concrete beam 10, a beam support 11 and pre-embedded section steel (not shown in the figure), and the steel pipe concrete pile includes a bottom Steel pipe 1, at least one unit steel pipe 2, loading plate 3 and drill bit 4.
[0080] The top outer walls of the bottom steel pipe 1 and the unit steel pipe 2 are respectively provided with external threads, and the respective bottom inner walls are provided with internal threads. The respective outer walls of the bottom steel pipe 1 and the unit steel pipe 2 are welded with helically encircling thread blades 5 at positions between the external thread and the internal thread. Utilizing the threaded vane 5 can effecti...

The invention discloses an assembled steel pipe recycled concrete pile and reinforced concrete beam assembly structure which comprises a steel pipe concrete pile, a reinforced concrete beam, a beam supporting part and pre-embedded section steel, wherein the steel pipe concrete pile comprises a bottom steel pipe, at least one unit steel pipe, a loading plate and a drilling bit; an external thread is arranged on the outer wall of the own top of each unit steel pipe; an internal thread is arranged on the inner wall of the own bottom of each unit steel pipe; recycled concrete blocks and self-compaction concrete can be poured into an internal steel pipe from the top of the unit steel pipe at the highest position; the beam supporting part is connected with the external thread on the top of the unit steel pipe at the highest position through a thread groove; the pre-embedded section steel is pre-embedded inside the reinforced concrete beam; and an accommodating groove used for accommodating the reinforced concrete beam is formed in the top of the beam supporting part. By adoption of the assembled steel pipe recycled concrete pile and reinforced concrete beam assembly structure, the steelpipe concrete pile can be easily driven into the earth section by section sequentially and rotationally when the cost is effectively reduced, and can be simply and firmly connected with the reinforcedconcrete beam.
Description
technical field [0001] The invention relates to an assembly structure of a steel pipe concrete pile and a concrete beam. Background technique [0002] Concrete-filled steel pipe pile is a composite structure with high bearing capacity, high plasticity, toughness, and convenient construction. At present, the concrete is usually poured into the steel pipe first, and then the whole is hammered into the ground or backfilled after digging a hole, which is time-consuming and labor-intensive and is prone to the situation that the backfill is not dense enough, especially when the piling is deflected, adjustment or Taking it out is more troublesome. For the recyclable concrete block, if it can be applied, the cost can be effectively reduced, which has great practical significance. Reinforced concrete beams are beams made of reinforced concrete material. The joints of the two are generally connected by steel bars around, which requires the installation of formwork and steel bar bin...
