Problems solved by technology

A single prefabricated concrete column weighs a lot, usually 20-30 tons, and after the three columns are stacked and poured, there is no gap between the columns for hoisting wire ropes, so it is very difficult for the columns to turn over, and a little carelessness

Abstract

The invention relates to a method for overturning a precast concrete column with a bent structure. The method is characterized by comprising the following steps: a) embedding a welding steel pipe (2) into the precast concrete column; b) processing two overturning hangers for the precast concrete column with the bent structure; c) penetrating a threaded end of a hanger (7) through the welding steel pipe (2) embedded in the precast concrete column with the bent structure; d) binding a hanging steel wire rope in the hanging lugs (11) at the top ends of two hangers and using a crane for hoisting; and e) placing three sleepers (10) on the ground at uniform interval, placing the precast concrete column with the bent structure onto the sleepers, loosening a nut, drawing out the hangers and completing the overturning of the precast concrete column. The method for overturning the precast concrete column with the bent structure provided by the invention has the advantages of simple structure of the hanger device, convenience in manufacturing, capability of increasing the overturning efficiency of the precast concrete column with the bent structure and capability of reducing the manufacturing quality risk of the precast concrete column with the bent structure.

Description

technical field [0001] The invention relates to a prefabricated concrete column, in particular to a method for turning over a prefabricated concrete column with a bent frame structure. Background technique [0002] The bent frame structure is composed of roof truss (or roof beam), column and foundation. The column is hinged to the roof truss and rigidly connected to the foundation. It is the basic structural form of a single-story factory building. The bent frame structure consists of roof trusses, columns and foundations to form a horizontal planar bent frame, which is the main load-bearing system of the factory building. The planar bent frames are connected by longitudinal components such as roof panels, crane beams, and supports to form an overall spatial structure. Due to the large number and large size of prefabricated concrete columns with bent frame structure in single-story factory buildings, they are usually prefabricated at the installation site. Due to the limitat...
