Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0026] refer to figure 1 , figure 2 , image 3 , a prefabricated column assembly construction method, comprising the following steps:

[0027] Step 1: Before the cap is poured, a number of steel bars are pre-embedded in the foundation pit, and a shaped template with positioning holes 2 is used to fix and position the steel bars. The steel bars correspond to the positioning holes 2 one by one; Crossbars and vertical bars, used as load-bearing supports for formwork;

[0028] Step 2, pouring the foundation pit, after the concrete is poured, remove the shaped formwork on the steel bars,

[0029] Step 3: Set the grout retaining formwork on the top surface of the cap platform. The ...

Abstract

The invention relates to the technical field of precast column construction, in particular to a precast column assembly construction method. The invention fixedly locates pre-embedded reinforcing barthrough a shaping template with a locating hole, then the column is positioned by using the mortar retaining formwork and the column limiting plate, brackets and adjusting jacks installed on upright posts, The utility model can make the lifting survey and positioning of the upright column accurate, improve the installation efficiency, satisfy the subsequent assembling construction of the precast cover beam, greatly improve the installation efficiency of the upright column, ensure the construction quality, reduce the input of the labor force on the construction site, shorten the time of the on-site construction operation, and promote the on-site construction and production progress.

Description

technical field [0001] The invention relates to the technical field of prefabricated column construction, in particular to a prefabricated column assembly construction method. Background technique [0002] With the development of my country's national economy and the progress of the production and application of mechanical equipment for prefabricated segmental assembly construction, especially the proportion of amortization costs of mechanical equipment in the total project investment is continuously decreasing, and labor costs are gradually on the rise, making segmental assembly construction In the prefabricated assembly process of bridge columns, since the height of prefabricated columns ranges from more than ten meters to tens of meters, the actual weight can reach hundreds of tons. For prefabricated column members with large volume and weight, when splicing with the bottom cap, it will have the problem of difficult control of horizontal positioning accuracy, which will af...
