Development of a new intelligent concrete spreading technology

Abstract

The concrete spreader is one of the key pieces of equipment for producing concrete components in the construction industry. Its performance directly affects the product quality and production efficiency of precast concrete components, which in turn affects the industrialization progress in construction. Due to manual operation, waste of concrete, and low spreading efficiency, it is difficult to achieve accurate spreading operation for complex prefabricated components. It is necessary to develop new technologies to improve the stability, accuracy, and intelligence level of the concrete spreader for producing complex prefabricated components. This paper proposed a new intelligent concrete spreading technology based on BIM (building information model) information parsing techniques, stabilized and precise concrete spreading techniques, grid casting model planning techniques, motion control techniques with heavy-loading and vary-loading, and advanced detection and control techniques. This new technology breaks through the bottleneck that restricts the stability, refinement, and intelligent development of concrete spreading for prefabricated components and promoted the overall development process of construction industrialization.
