Prefabricated column hoisting method

Abstract

The invention belongs to the technical field of prefabricated construction, and particularly relates to a prefabricated column hoisting method. The prefabricated column hoisting method comprises the following steps that the distance between brackets at the two ends of a prefabricated column is measured by using a measuring tape, and two steel frames are placed through calculation of the distance;the two ends of the prefabricated column are wrapped up by using crimped angle steel groups respectively, then bindingly fixed well by using first steel wire ropes, hoisted and placed on the steel frames; the first steel wire ropes and the crimped angle steel groups at the two ends are taken off, one of the crimped angle steel groups is fixed to the hoisting point at the 1 / 3 position of the prefabricated column, two second steel wire ropes are bound to the hoisting point separately, and the hoisting point is controlled to the position under the arm of the corresponding bracket; a crane hooks the second steel wire ropes by using two hoisting hooks respectively, after crane loading, the second steel wire ropes are stressed and can be released and withdrawn to a safe area, the crane is loaded, and the prefabricated column is gradually vertically hoisted and fixed in position. The method is simple and easy to operate, the scratch between the brackets and the ground during hoisting is effectively avoided, and meanwhile, the hoisting safety is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of prefabricated buildings, and in particular relates to a hoisting method of a prefabricated column. Background technique [0002] In the field of prefabricated buildings, prefabricated components save the trouble of messy construction materials, many variable factors, and difficult management. All components are produced and maintained in a unified factory. The quality of components in this way is guaranteed, which is beneficial to energy saving Environmental protection is of great benefit, but how to hoist prefabricated components safely and efficiently has always been our goal. In the prior art, high-fiber cloth belts are often used for hoisting, which is severely worn and has potential safety hazards. At the same time, the corbels are not protected. When lifting, the corbels will rub against the ground. Face deformation. Contents of the invention [0003] The present invention aims to solve the abov...
