Problems solved by technology

If this method is used to prepare large L-shaped prefabricated terrazzo decorative hanging panels, the stones will sink after the terrazzo concrete is vibrated, and there are many stones on the bottom surface of the terrazzo prefabricated component, but there are very few stones on the side, which are basically mortar and hardened. After demoulding and grinding, the decorative effect is significantly different from that of the bottom surface, and the thickness of grinding must be at least 5mm to expose stones. The production process is troublesome, the cost is high, and the later maintenance cost is high

Abstract

The invention discloses a preparation method of an L-shaped precast terrazzo decoration hanging board. The method comprises the following steps of 1, preparing raw materials; 2, cleaning and placing amold; 3, pouring concrete at the plane portion; 4, casting corner portions; 5, performing surface finishing, drawing and repairing; 6, performing polishing, and performing protective agent coating. By adopting the rock filling technology, after reinforce cages at the corners are filled with black and white yonaishi, irrigation is performed; during polishing, the density of the black and white yonaishi is basically equivalent to the bottom face of the terrazzo decoration hanging board, little slurry is adopted, the polished depth is basically the same as that of the bottom face of the decoration hanging board, and the technical problems that in the traditional technology, little stone exists at the side faces of the corners of existing L-shaped precast terrazzo decoration hanging boards, and the polishing depth is large are solved.

Description

technical field [0001] The invention belongs to the technical field of wall decoration, and in particular relates to a preparation method of an L-shaped prefabricated terrazzo decorative hanging board. Background technique [0002] In the current construction industry, the production process of terrazzo prefabricated components is relatively mature, mainly including prefabrication and cast-in-place. The pre-ordered terrazzo parts produced by these two methods are about 1m×1m in size, small in size and high in strength. For laying the ground, it is rarely used in the field of large-scale wall appearance decoration. Therefore, in the production of large-area terrazzo prefabricated components, different production processes are required to ensure its flatness and quality. [0003] At present, the preparation method of L-shaped large-area terrazzo prefabricated parts often adopts the traditional planar prefabricated component production process, such as the production process of...
