Abstract

The invention relates to a high-bending-resistance hold hoop joint mechanically connected with a precast concrete beam-column pile rod. The hold hoop joint comprises two reinforcing hoops which are oppositely arranged, and a plurality of reinforcing ribs are fixedly connected to the inner side of each reinforcing hoop; a positioning groove and a sealing groove are horizontally formed in the outercircle face of each reinforcing hoop at intervals, a stress ring is arranged in each positioning groove, and a sealing ring is arranged in each sealing groove. An outer hoop sleeves the outer side ofthe two reinforcing hoops, a groove corresponding to each positioning groove is formed in the inner side wall of the outer hoop, a threaded fastener penetrating through the grooves is arranged on theouter hoop, and the threaded fastener is used for fixing the outer hoop and the stress rings to the reinforcing hoops in an abutting mode together. According to the hold hoop joint, manual welding process operation is avoided, the quality is controllable, mechanical connection is reliable, the labor intensity is reduced, the anti-corrosion performance is good, the steel consumption is extremely low, and the product cost and the construction cost are greatly reduced.

Description

technical field [0001] The invention relates to a hoop joint for strong bending mechanically connecting prefabricated concrete beam-column piles. Background technique [0002] The current concrete poles, wind power concrete tower poles, etc., the joints in the middle are mainly connected by the large flanges of each pile head, which consumes a lot of steel and requires a lot of manual welding. When assembling, high-strength bolts are used to connect, which can only be done manually. Tighten the bolts, so the overall cost of each joint is about 1,000 yuan, the quality of the connection is also unstable due to human influence, and the flange and the connecting bolts are exposed, the anti-corrosion effect is poor, and the service life is short. However, prefabricated piles are not allowed to have pile joints in the soft soil and quicksand liquefaction geological conditions, which affects the popularization and use of prefabricated piles. Therefore, most of the cast-in-place pil...
