Problems solved by technology

[0003] The purpose of the present invention is to provide a building 3D printed wall column structure and its construction method. To solve the problem that the existing 3D printing equipment cannot perform on-site printing around the steel cage that has been constructed, only assembled nodes can be used, resulting in building costs. High, affecting the construction quality, the on-site 3D printing building construction structural column has poor building integrity and low structural safety

Embodiment Construction

[0032] see Figure 1-4 As shown, a building 3D printed wall column structure, including concrete structure base plate 1, embedded steel bar 2, steel bar sleeve 3, lapped steel bar 7, structural column steel cage, 3D printed outer wall 4, 3D printed inner wall Body 6, 3D printing wall inner rib 5 and cast-in-place column concrete 9, the structural column reinforcement cage includes vertical main reinforcement 8 and horizontal reinforcement.

[0033] The shape of the 3D printed outer wall 4 and the 3D printed inner wall 6 are both L-shaped. The corners of the printed inner wall 6 and the two 3D printed inner wall ribs 5 are jointly enclosed to form a column formwork for pouring the cast-in-place column concrete 9, and the two ends of the 3D printed inner wall ribs 5 are respectively fixed and connected to the Print the outer side of the inner wall body 6 and the inner side of the 3D printed outer wall body 4 .

[0034] A group of pre-embedded steel bars 2 are pre-embedded at t...

Abstract

The invention discloses a 3D-printed wall column structure of a building and a construction method of the structure. The wall column structure comprises a concrete structure bottom plate, embedded bars, a 3D-printed inner wall body, a 3D-printed outer wall body, 3D-printed wall body inner ribs, a structure column reinforcement cage and cast-in-place column concrete. According to the structure andthe method, construction of the 3D-printed wall bodies is performed by the aid of special onsite 3D printing equipment, lapped bars are connected with the embedded bars through bar sleeves after printing construction reaches the certain height, the structure column reinforcement cage is mounted after printing construction is continued to reach the single-layer height, the cast-in-place concrete iscast finally, and thus the structure column and the 3D-printed wall bodies form an integral structure. According to the structure and the method, the problems of poor integrity and low structural safety of the onsite 3D-printed building are solved, the structural stability of the onsite 3D-printed building technology is improved, and the construction quality is guaranteed.

Description

technical field [0001] The invention belongs to the field of building construction, in particular to a building 3D printed wall column structure and a construction method thereof. Background technique [0002] Concrete (mortar) 3D printing equipment cannot carry out on-site printing construction around the completed steel cage. Therefore, the current 3D printing buildings mostly adopt the form of 3D printing prefabricated components produced in the factory and assembled on the construction site. This kind of construction The form not only increases the construction process of on-site assembly, but does not reflect the characteristics of intelligent construction of 3D printed buildings, but also the installation of assembly nodes affects the integrity of the building to a certain extent, increases the manufacturing cost of the building, and affects the quality of the building. Construction Quality. Contents of the invention [0003] The purpose of the present invention is ...
