Abstract

The invention discloses a prefabricated concrete pile mechanical connector which comprises a connecting pipe, a clamping and fixing piece, an inserting rod and a tensioning sleeve. The connecting pipe comprises a connecting pipe main body and a first main reinforcement connecting part; the clamping piece is arranged in the connecting pipe main body; the tensioning sleeve comprises a sleeve main body and a second main reinforcement connecting part; the insertion rod comprises an insertion rod fixing part and an insertion rod clamping part; the inserting rod fixing part is connected with the tensioning sleeve; the length of the clamping part of the inserting rod is greater than or equal to three times of the diameter of the main rib; the length of the internal space of the connecting pipe is greater than or equal to three times of the diameter of the main rib; and the clamping part of the inserting rod can be inserted into the connecting pipe and is clamped with the clamping piece. The prefabricated concrete pile mechanical joint disclosed by the invention realizes real coaxial and consistent connection of pile-forming main reinforcements, so that the shearing resistance, bending resistance and pulling resistance of one pile are optimal.

Description

technical field [0001] The invention relates to the technical field of prefabricated concrete pile mechanical joints, in particular to a prefabricated concrete pile mechanical joint. Background technique [0002] With the continuous improvement of my country's economic level, the mechanical joints of precast concrete piles have experienced a rapid development stage from the introduction of advanced products, technologies and processes from Japan to the independent research and development of new products and new processes. One of the largest countries with the most varieties, the most complete specifications and the widest range of applications. According to statistics, the output of mechanical joints of precast concrete piles in my country will be 453.62 million meters in 2020, a year-on-year increase of 5.44%. At the same time, higher requirements are put forward for the vertical bearing capacity of the pile and the comprehensive performance of bending resistance, shear re...
