With the improvement of productivity and people's living standard, the demand of individuation is more and more prominent. It has also become a dream for many people to have a house with its own unique appearance. The construction industry has always been an industry that needs human, material and physical strength. Because the only child is the majority of the population structure type, the construction industry employment population is also less and less. The emergence of building 3D printer can not save the manpower of building houses, save the material resources of formwork erection, but also build houses of opposite sex with individual needs. The more complex the structure, the more able to reflect the advantages of building 3D printers. It has to be said that the 3D printer is the product of the times, the need of the times and the trend of history!
Building 3D printer is a set of equipment used to print reinforced concrete houses on the construction site. There are mainly four system components: 1. Electronic batching system 2. Automatic feeding system 3. Printing system 4. Overall lifting system.
1. Electronic batching system
The main raw materials of building 3D printer are sand, cement, stone and water. In order to meet the needs of printer printing, there are strict requirements on the proportion. The electronic batching system can accurately and quickly handle the proportion of various materials. The raw materials for printers are made by mechanical mixing. The raw materials for printers should meet the sampling and inspection standards of the national inspection department.
2. Automatic feeding system
The automatic feeding system realizes the continuous supply of raw materials to the printer to ensure that the printer has enough raw materials for printing.
3. Printing system
Printing system is the key part of the whole set of equipment. A) According to individual needs, design the outline drawing of the house. Input the drawings into the printed CNC system. B) According to the house structure, arrange the steel structure, and process the shape of the steel in the factory in advance. C) Bind the reinforcement on site and correct the size of the overall reinforcement. D) The printer shall be arranged on site. The printer nozzle shall be symmetrically arranged on both sides of the reinforcement wall. The printer shall print the house outline layer by layer according to the walking track of the input drawing data. E) Arc angle design of building. Because all corners of the design house are arc angles, it not only ensures the fluency of overall printing, but also increases the overall seismic resistance of the house.
4. Integral lifting system
When the printer is printed to a certain height, the printer will be lifted once as a whole, and the printer and printing completion building will be connected together to form a solid whole. After lifting, the printer will continue to print until the height of the house meets the design requirements.
The appearance of 3D printer in architecture realizes the application of NC technology in manufacturing industry. Building 3D printer direct printing molding technology, the template process is cancelled, the project cost is reduced, mechanical construction is used instead of manual construction, the construction period is shortened, and the construction speed is accelerated. It solves the problem of labor shortage in the construction industry, and reduces the scene of workers rushing to work in full swing. Try to see the future of the construction industry, will be the scene of 3D printing house world!
