Precise molding method of spatial curved surface GRC curtain wall

Abstract

The invention provides a precise molding method of a spatial curved surface GRC curtain wall. The method improves the molding precision, quality and safety guarantee of GRC curtain wall unit plates and reduces construction rework of a curtain wall, anchoring plate falling and other problems. The method is characterized by including the steps that 1, parameters of the GRC curtain wall unit plates are refined; 2, a mold and a back-attached steel frame are manufactured; 3, a support system is installed; 4, a positioning beam is mounted; 5, a mold release agent is sprayed; 6, a decorative layer issprayed; 7, the back-attached steel frame is mounted; 8, embedded parts are installed; 9, a fiber net is laid; 10, fiber mortar is sprayed; 11, maintaining is carried out; 12, demolding is performed.According to the method, the molding precision, quality and safety guarantee of the GRC curtain wall unit plates can be improved, and construction rework of the curtain wall, anchoring plate fallingand other problems can also be avoided.

Description

technical field [0001] The invention relates to the field of design and construction of building curtain walls, in particular to an accurate forming method of a space curved GRC curtain wall which improves the forming accuracy, quality and safety guarantee of GRC curtain wall unit plates, and reduces the problems of curtain wall construction rework and anchor plate falling off. . Background technique [0002] The special-shaped GRC curtain wall with space curved surface has a strong visual impact and artistic expression effect, but it also poses a lot of challenges to the construction of the main structure and curtain wall. [0003] Before the construction of the GRC curtain wall, the structural entity has been completed, but there are often certain construction errors between the structural entity and the original design, especially for some large-scale space curved surface special-shaped structures, deviations are almost inevitable, and such structures are often of great i...

AI Technical Summary

Problems solved by technology

There is delamination between the anchor plate of the GRC curtain wall unit plate formed by secondary casting and the GRC curtain wall unit plate. Especially in winter, the tensile strength of the anchor plate of the GRC curtain wall unit plate produced in winter is low. During the test, a high proportion of anchor discs fell off, which often caused serious quality and safety hazards, and brought great challenges to the production and use of GRC curtain wall unit panels
