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 3D printing with formwork collaboration and a construction method thereof and belongs to the technical field of building construction. The bridge 3D printing device comprises a guide frame, a guide rail travelling mechanism, a bridge 3D printing mechanism, a rail 3D printing mechanism and a collaborating formwork; the guide frame provides supporting for the bridge3D printing mechanism, the rail 3D printing mechanism and the collaborating formwork; the rail 3D printing mechanism provides 3D printing for a rail support structure; the guide rail travelling mechanism supports the guide frame the rail support structure that is constructed; the bridge 3D printing mechanism can print a bridge body; the collaborating formwork can provide supporting for the bridgebody during printing. The bridge 3D printing with formwork collaboration and the construction method thereof have the advantages that complex formwork erection and removal operations during traditional bridge printing are avoided so that construction efficiency is improved; the bridge 3D printing with formwork collaboration can provide full-automatic continuous printing.

Description

technical field [0001] The invention relates to a 3D printing device and a construction method for a bridge with template cooperative operation, 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 mol...
