Prefabricating device and method for UHPC column formwork

Abstract

The device comprises an outer mold, an inner mold, a bottom mold, an operation platform, a ladder, a material distributor and a top cover plate, the lower end face of the bottom mold is fixedly installed on the platform, the inner mold is installed on the upper end face of the bottom mold, the outer mold is installed on the outer side of the inner mold, and the ladder is installed on the outer side of the inner mold. The bottom end face of the outer mold is connected with the upper end face of the bottom mold, the operation platform is installed on the side face of the upper portion of the outer mold, the distributing device is installed on the end face of the upper portion of the outer mold, and the top cover plate is installed on the upper end face of the distributing device. The invention further relates to a method for prefabricating the UHPC column formwork. The supporting device is arranged on the inner wall of the inner mold, after concrete pouring is completed, the inner mold is separated from the inner wall of concrete through shrinkage, and the construction efficiency is improved; and the outer mold is spliced through the eccentric quick locking device, so that the splicing precision and the use safety of the outer mold are improved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a prefabrication device and method for UHPC column formwork. Background technique [0002] With the continuous development of urbanization and the continuous advancement of construction industrialization, prefabricated construction technology has become more and more widely used. In addition to civil housing construction and traffic road engineering construction, large public buildings have gradually begun to adopt prefabricated construction methods. On the one hand, there are Help to speed up the construction progress, on the other hand in line with the concept of environmentally friendly development. However, due to the large space characteristics of large public buildings, the size of the components is relatively large, which brings a series of problems to transportation and lifting. Therefore, the overall prefabricated structure is turned to partial prefabrication, and...

Problems solved by technology

[0004] Ultra-High Performance Concrete (UHPC) has excellent properties such as ultra-high strength, high toughness, high impermeability and high corrosion resistance, and is expected to become the basic material for the next generation of infrastructure construction. The installation position of the shell is to install the mold first, and then the concrete is poured. Due to the limitation of the installation position of the column formwork, the pouring is inconvenient and the construction period is long.
