The invention relates to a
digital manufacturing and construction method for a special-shaped
stone veneer in a large venue, and aims to solve the problems of low
machining precision, high mounting difficulty, low construction efficiency and the like of special-shaped stone in construction of an outer vertical face and an inner
veneer of a building. The method comprises the following steps: firstly, measuring a building special-shaped structure by using a three-dimensional
scanner or a BIM (
Building Information Modeling) technology to generate a three-dimensional geometric model; based on the model, combining the material characteristics of the stone, and optimizing the geometric shape and size of the stone through a typesetting
algorithm; then the optimized data are imported into five-axis CNC
numerical control equipment for precise
cutting; pre-
assembly is conducted after
cutting, errors are detected through
laser scanning equipment, and adjustment is conducted till the precision requirement is met; and finally, a
laser positioning system and a
mechanical sensor are combined, a manual construction team manually installs the stone, and it is ensured that the installation precision meets the design requirement. According to the method, the
machining and mounting precision of the special-shaped stone is effectively improved, the construction efficiency is improved, and the
structural safety and the attractive effect of a building are guaranteed.
