Column-pile combined cover nut and use method thereof

Abstract

The invention relates to a column-pile combined cover nut and a use method thereof. The column-pile combined cover nut is formed by splicing at least two cover nut valve bodies, wherein each valve body is composed of an arc-shaped sleeve body, a fan-shaped sleeve cover connected with the upper side of the arc-shaped sleeve body, and an upper raised head connected with the center of the fan-shaped sleeve cover, a pin hole is formed on the arc-shaped sleeve body and is matched with a locating pin at a metal cap of the top of a prestress pipe pile. The column-pile combined cover nut further comprises at least one arc-shaped hoop sleeved outside the arc-shaped sleeve bodies of the cover nut valve body, so as to hoop the cover nut valve bodies together; and anti-slip barrier strips are also arranged outside the arc-shaped sleeve bodies to limit the arc-shaped hoops. The column-pile combined cover nut also comprises a head frame which is used for binding the upper raised heads of the cover nut valve bodies together and is locked on the fan-shaped sleeve covers through fastening bolts; and each fan-shaped sleeve cover is provided with a locking device connected with a steel column. The column-pile combined cover nut can make the best of the prestress pipe pile, so as to achieve the purpose of one pile with two functions, and realizes the purposes of shortening construction period, reducing construction cost and improving social benefit.

Description

technical field [0001] The invention relates to a post-pile combination sleeve cap for socketing a tool-shaped steel column on a prestressed pipe pile, and specifically discloses a method for using the post-pile combination sleeve cap. Background technique [0002] At present, in the earthwork support engineering with internal support, the supporting columns are set separately, and the root-drawing columns are pre-buried in the soil. Usually, cast-in-place piles with steel columns or steel-concrete structures are used. The body is a one-time setting, and the columns are often non-standard structures and cannot be reused. After the support project is completed, the cast-in-place piles or steel-concrete structures below the basement have to be discarded, and the columns above are only for waste recycling, so it is very important. waste. Contents of the invention [0003] The purpose of the present invention is to provide a pile cap and its use method. The pile cap is reason...

[0002] At present, in the earthwork support engineering with internal support, the supporting columns are set separately, and the root-drawing columns are pre-embedded in the soil. Usually, cast-in-place piles with steel columns or steel-concrete structures are used. The body is a one-time setting, and the columns are often non-standard structures and cannot be reused. After the support project is completed, the cast-in-situ piles or steel-concrete structures below the basement have to be discarded, and the columns above are only for waste recycling, so it is very important. waste
