Embodiment Construction

[0009] Such as Figure 1-2 As shown, a fully prestressed solid square pile end plate, including a square bottom plate 1, is provided with 24 threading holes 3 around the bottom plate 1 for passing steel bars. The diameter of the threading holes 3 is 16mm, and the inner side of the threading holes 3 An anchor hole 4 for the pile connection is provided, and the diameter of the anchor hole 4 for the pile connection is 45 mm. The outer edge 2 of the bottom plate 1 is folded up so that the angle between the bottom plate and the outer edge is 115 degrees. The thickness of the bottom plate 1 is 4.0mm.

[0010] The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Anyone familiar with the technical field within the technical scope disclosed in the present invention, according to the technical solution of the present invention Any equivalent replacement or change of the inventive concepts th...

Abstract

The invention discloses a full pre-stressing solid square pile end board which comprises a square bottom board (1). A plurality of threading holes (3) enabling reinforcing steel bars to penetrate are formed in the periphery of the bottom board (1), a pile splicing anchoring hole (4) is formed in the inner side of each threading hole (3), and an outer edge (2) of the bottom board (1) is folded upwards. The full pre-stressing solid square pile end board is arranged on the end portion of a square pile, a main reinforcing bar is located through the end board, and after the stretch-draw stress is exerted on the end board, the phenomenon that the accuracy of a stretch-draw stress value is influenced due to natural deflection caused by the length of the pre-stressing main reinforcing bar is avoided. The section face, generated by the end board, of the pre-stressing square pile is not flat and the cracking resistance when piling is conducted is improved. The end board is used for producing the pre-stressing square pile, so that labor and time are saved, quality is guaranteed, the production efficiency is improved, the job progress is guaranteed, the economic benefit of an enterprise is improved, and high praise of a user can be obtained.

Description

technical field [0001] The invention relates to a building concrete pile foundation structure, in particular to a fully prestressed solid square pile end plate. Background technique [0002] In the production process of fully prestressed solid square piles (ordinary piles), the pile top is often uneven and not vertical, which causes the pile to be deviated and tilted during the pile sinking process. Moreover, the front pile ends are all planes, and the piles are also easily broken during the striking process. The pile top was broken and damaged and could not be used without reaching the design bearing layer requirements, resulting in a lot of waste and affecting the construction progress. The fully prestressed solid square pile is produced on a long-line platform, and its prestressed main reinforcement is very long, which naturally produces a large deflection, which affects the accuracy of the prestressed setting value. Therefore, the number and diameter of reinforcement f...
