Resin lining steel molding plate for undevelopable cone curve face structure and manufacturing method thereof

Abstract

The invention discloses a resin lining steel molding plate for an undevelopable cone curve face structure. The resin lining steel molding plate comprises a steel framework manufactured according to a conventional method. The steel framework is fixedly connected with more than two trapezoidal panels, slits of 0-20mm are formed between the adjacent trapezoidal panels, the slits between the trapezoidal panels are sealed, and epoxy resin glass fiber layers are integrally arranged on the front of the trapezoidal panels and the slits of the trapezoidal panels to form the resin lining steel molding plate consistent with the shape of the undevelopable cone curve face. The invention further discloses a manufacturing method for the resin lining steel molding plate for the undevelopable cone curve face structure. By utilizing the characteristics of the steel molding plate and epoxy resin, the large steel framework resin lining steel molding plate having the existing strength and rigidity and conforming to the surface shape of the structure is obtained through a simple manufacturing process, the structure surface shape molding plate conforming to a design drawing is formed, and the design idea is achieved well.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a resin-lined steel formwork for structures with non-developable conic curve surfaces and a manufacturing method thereof. Background technique [0002] With the rapid development of urban infrastructure construction, more and more large-scale structures such as urban road overpasses and overpasses stand between various urban areas. For the landscape effect, city administrators put forward to the builders the construction concept of first-class function, one bridge and one scene to meet the increasing demand for urban beautification, thus creating a variety of special-shaped structures, especially the substructure of urban bridges is particularly prominent, Square vases, elliptical vases, hyperbolic table tops, conic surface vases and other irregular and special-shaped pier columns came into being. These structures are generally required to be fair-faced concrete structure...

AI Technical Summary

Problems solved by technology

[0005] 1. Since the surface of the building object is a non-expandable conical surface, the expansion diagram cannot be obtained when making the template

The blanking of the formwork panel is difficult, and the splicing is very difficult

[0006] 2. Most of the templates are large-scale steel templates, and the approximate expansion method cannot be used to achieve accurate blanking. The amount of trimming in the production process is too large (the amount of welding is also large), and the weld seam is wide

[0007] 3. It is made by the straight instead of curved method, which has many joints, large welding volume, difficult to control the deformation, and cannot guarantee the smoothness of the formwork, which cannot meet the construction requirements of fair-faced concrete
