Novel sleeve pile without end plates

Abstract

The invention relates to a novel sleeve pile without end plates. The novel sleeve pile comprises a pile body and a cage rib structure internally arranged in the pile body, wherein the pile body is ofa hollow cuboid or cylinder structure; the cage rib structure is fixedly connected with the pile body, and composed of a plurality of prestressed steel ribs extending in the axial direction of the pile body and annularly distributed, and annular stirrups welded to the peripheries of the prestressed steel ribs; the prestressed steel ribs are uniformly or non-uniformly distributed; the two ends of each prestressed steel rib are headed; sleeves sleeve the two sides of each prestressed steel rib separately; and the sleeves are fixed into the pile body. The novel sleeve pile disclosed by the invention has the following advantages: the traditional prestressed pile is improved, end plates at the two sides are removed, and the independent sleeves sleeve the two ends of each prestressed steel rib to replace the end plates, and in this way, when the novel sleeve pile is connected with a head plate and a tail part, each sleeve is independently connected, so that the mutual influence is reduced; and moreover, screws can be driven by virtue of a pneumatic wrench, and the operation is convenient and rapid, and high in efficiency, so that the labor intensity of workers is lowered.

Description

technical field [0001] The invention relates to a pile, in particular to a novel sleeve pile without an end plate. Background technique [0002] At present, the concrete piles used in the market are generally divided into two types: pipe piles and square piles. Among them, pipe piles are divided into prestressed concrete pipe piles and prestressed high-strength concrete pipe piles according to the concrete strength grade or effective precompression stress. The prestressed concrete pipe pile is code-named PC, the prestressed high-strength concrete pipe pile is code-named PHC, and the thin-walled pipe pile is code-named PTC. The concrete strength of PC piles shall not be lower than C60, the strength grade of thin-walled pipe piles shall not be lower than C60, and the concrete strength grade of PHC piles shall not be lower than C80. [0003] Square piles are divided into prestressed concrete square piles, prestressed high-strength concrete square piles code-named PC, and pres...

Problems solved by technology

In such a production process, when fixing the end plate and the head and tail plate, bolts, etc. are required for fixing, and the two plates are fixed in a multi-hole way. If there is a deviation in a hole, the It is more difficult and cumbersome to fix the remaining holes, and the labor intensity of the workers is high; in addition, when the diameter of the main reinforcement of the processed steel cage changes, the end plates and the head and tail plates all need to be replaced accordingly, and the versatility is not strong; and For the filling or square pile formed in this way, the end plate is finally fixed with the concrete pile body and cannot be disassembled, that is, each pipe pile or square pile needs to be equipped with two independent end plates, and the cost is relatively high
