Problems solved by technology

Due to the limitations of materials and devices, it is difficult to realize the automatic construction of horizontal components without manually erecting the bottom formwork. Therefore, 3D printed reinforced concrete bridges need to manually support the bottom formwork, which is difficult to support the formwork, and printing cannot be fully automated. , In addition, the speed of 3D printing bridges is extremely slow, and the flatness of the printed bridge surface cannot be controlled. The printing device automatically climbs up with the help of the printed bridge structure. Due to the rough surface, it cannot be accurately positioned, resulting in low printing accuracy and error accumulation.

Abstract

The invention relates to a bridge engineering 3D printing device and a construction method, and belongs to the technical field of building construction. The device comprises a guiding frame, a guidingrail walking mechanism, a bridge 3D printing mechanism and a rail 3D printing mechanism; the bridge 3D printing mechanism and the rail 3D printing mechanism are supported by the guiding frame, 3D printing of a rail supporting mechanism is achieved by the rail 3D printing printing mechanism, the guiding frame is supported on a rail supporting structure of which construction is completed by the guiding rail walking mechanism, and printing of a bridge foundation and a bridge body are achieved by the bridge 3D printing mechanism. According to the construction method, the rail supporting mechanismof which construction is completed is thoroughly adopted as a support, printing of the rail supporting structure for supporting walking of the guiding rail walking mechanism and for walking of the guiding rail walking mechanism is achieved while printing and construction of a 3D printing bridge are achieved, so that full-automatic and constant printing of the 3D printing bridge is achieved, and the device has the advantages of being high in printing accuracy and speed and safe in construction.

Description

technical field [0001] The invention relates to a bridge engineering 3D printing device and a construction method, belonging to the technical field of building construction. Background technique [0002] In recent years, countries around the world have successively issued programmatic documents such as "National Strategic Plan for Advanced Manufacturing (USA), "Industry 4.0 Plan (Germany)", and "Made in China 2025", all of which regard additive manufacturing (3D printing) as a national priority. Strategy. [0003] The degree of mechanization and automation of the traditional construction industry is low, and its development urgently needs transformation and upgrading. With the development and maturity of 3D printing technology, this technology will bring technological innovation to the labor-intensive construction industry. Architectural 3D printing technology has the characteristics of high degree of mechanization and automation, one-time molding, less construction consum...
