A prefabricated column formwork and its application method

Abstract

The invention discloses a prefabricated column formwork and an application method thereof. The prefabricated column formwork and the application method thereof mainly solve the problems that currently a column formwork needs to be assembled and disassembled on site, and the phenomenon of formwork expansion occurs easily. The prefabricated column formwork comprises a column formwork body, opposite-pull fixing holes, exposed reinforcing steel bars, disassembling and assembling hoisting point components and hoisting bolts, wherein the cross section of the column formwork body is in a right-angle U shape, the column formwork body is of an integrated structure, the opposite-pull fixing holes are formed in the two opposite edges of the column formwork body, correspond to each other and are used for enabling split bolts to be mounted, the exposed reinforcing steel bars are arranged on the column formwork body and are used for being connected with a cast-in-situ column, the disassembling and assembling hoisting point components are arranged on the right-angle U-shape bottom edge of the column formwork body, and the hoisting bolts are arranged on the two opposite edges of the column formwork body and correspond to each other. According to the prefabricated column formwork and the application method thereof, the column formwork body is designed to be of an integrated prefabricated concrete structure, the prefabricate column formwork makes contact with a prefabricated outer wall, and thus construction quality is ensured on the smoothness and mounting accuracy. Meanwhile, the cast-in-situ column is located in the prefabricated column formwork of the concrete structure, and thus the problem that the size of the appearance of the column cannot be controlled to the millimeter level through a traditional formwork and a wooden formwork of the cast-in-situ column, and formwork expansion occurs easily are solved effectively.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a prefabricated column form and its application method. Background technique [0002] In recent years, construction industrialization has received strong support from the state, and various provinces and cities have successively introduced various preferential and encouraging policies for construction industrialization, and enterprises expecting to develop construction industrialization have sprung up like bamboo shoots after rain. In the traditional construction mode, it is necessary to use wood formwork or steel formwork, plus the support of its own prefabricated beams and prefabricated slabs, which complicates the support system, so the column formwork came into being. The support system of the column formwork is relatively small, and the appearance of the column formwork is easy to decorate, and it can also be used as a vertical structure. It is i...

Problems solved by technology

[0003] However, in the prior art, the column formwork is in the form of a hollow column structure composed of several column formworks. The column formwork is usually placed separately and installed on site when used. After use, the formwork is removed, which is time-consuming and laborious.

Moreover, when the column formwork is applied, the prefabricated exterior wall is spliced ​​with the cast-in-place column, because the traditional steel formwork and wooden formwork cast-in-place cannot control the appearance size of the column to the millimeter level, and problems such as mold expansion are prone to occur, which greatly affects the affect the quality of the project
