Embodiment Construction

[0022] The present invention is described in further detail below in conjunction with accompanying drawing:

[0023] The prefabricated column hoisting construction method in place of the present invention specifically includes the following steps

[0024] 1) Before the concrete pouring of the prefabricated column 1, if figure 1 As shown, three PVC pipes are pre-embedded at the design position, two of which are used as turning holes 3, and one is used for lifting holes 4. If it is a corbel-shaped prefabricated column, the lifting holes are pre-embedded under the corbel. The axis directions of the two turning holes 3 are parallel to the brick membrane 2, which is beneficial to the accuracy of the pre-embedded position, and ensures that when the prefabricated column 1 translates and turns over, the angle between the hoisting rope and the horizontal line is 45°, which is balanced and evenly stressed; the lifting holes The 4-axis direction is perpendicular to the brick membrane 2,...

Abstract

The invention discloses a construction method for a prefabricated column to be lifted in position for one time. Before concreting, turning-over holes and lifting holes are embedded at designed positions through polyvinyl chloride (PVC) pipes, and mechanically connected lifting riggings are matched, so that the precast column bears force equally and uniformly during lifting. The method aims to protect finished products and avoid dangers of high-altitude rigging dismounting during one-time lifting in position of a precast column. According to the construction method, the construction is simple, the operation safety factor is high, the cost of a prior embedded disposable steel ring is saved, and the lifting efficiency and the safety are improved. According to the construction method, a large-size prefabricated part can be lifted in position once and the construction procedure is simplified in a lifting process of the large-size prefabricated part.

Description

technical field [0001] The invention belongs to the technical field of hoisting construction, and relates to a hoisting construction method, in particular to a prefabricated column hoisting one-time in-place construction method. Background technique [0002] In the prior art, the prefabricated columns are often hoisted using the traditional pre-embedded hoisting rings combined with steel wire rope binding hoisting construction methods. The cost of pre-embedded steel lifting rings is high, and the binding of steel wire ropes is not conducive to the protection of finished products; it is dangerous for operators to remove the binding ropes at high altitudes, and the lifting efficiency is low; the lifting force is uneven, which affects the quality of lifting. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a construction method for hoisting prefabricated columns once in place....
