Embodiment 1

[0073] This embodiment provides a device for preparing building structures based on 3D printing, such as figure 2 and image 3 As shown, it includes: 3D printing device 1 and reinforcement device.

[0074] Among them, such as figure 2 As shown, the 3D printing device 1 has a material storage chamber 11 inside, and accommodates cement-based materials to be printed. The end of the material storage chamber 11 is connected with a nozzle 12; the nozzle 12 and the reinforcement device are both moved relative to the base frame.

[0075]For example, the 3D printing device as a whole or the nozzle is set on the moving mechanism, which moves relative to the base frame under the drive of the moving mechanism. The moving mechanism can include a lift and a manipulator fixed on the lift, or a sliding part fixed on the lift. Optionally, it can be a cylinder, and the nozzle is fixed on the telescopic shaft of the cylinder, so as to realize the movement of the nozzle of the 3D printing dev...

Embodiment 2

[0109] The equipment for preparing building structures based on 3D printing provided by this embodiment, such as Figure 5 and Image 6 , which includes: a 3D printing device 1 and a reinforcement device.

[0110] Compared with the equipment for preparing building structures based on 3D printing provided in Example 1, the difference is that the temporary storage mechanism in Example 1 is not provided in the reinforcing device. However, in the equipment for preparing a building structure based on 3D printing provided in this embodiment, the reinforcement device includes a straightening mechanism 4 and a cutting assembly 2 .

[0111] Wherein, the cutting assembly 2 is used for cutting long steel bars or long bars into short steel bars or short bars. The straightening mechanism 4 has a straight channel extending along the conveying direction of the long steel bar or the long bar and passing through by the long steel bar or the long bar, so as to adjust the levelness or vertical...

Embodiment 3

[0122] The equipment for preparing building structures based on 3D printing provided by this embodiment, such as Figure 7 , Figure 9a as well as Figure 9b As shown, it includes: 3D printing device 1 and reinforcement device.

[0123] Compared with the equipment for preparing building structures based on 3D printing provided in Example 2, the difference is that the setting position and setting direction of the straightening mechanism 4 of the reinforcement device and the cutting assembly 2 change; the setting direction of the driving mechanism 3 The setting forms are different. In addition, the reinforcement device also includes a bending mechanism 6 and a feeding mechanism 7 .

[0124] like Figure 7 As shown, the reinforcing device includes a driving mechanism 3 , a straightening mechanism 4 , a cutting assembly 2 , a bending mechanism 6 and a feeding mechanism 7 . Wherein, the feeding mechanism 7 is arranged before the straightening mechanism 4 to drive the long steel...

Abstract

The invention discloses a device and a method for preparing a building structure based on 3D printing. The device comprises a 3D printing device and a steel bar loading device; the 3D printing devicecomprises a material storage cavity and a spray head which is connected with the material storage cavity and can move relative to a base frame; the steel bar loading device comprises a temporary storage mechanism, a filling mechanism and a driving mechanism, wherein the temporary storage mechanism is used for storing short steel bars or short stripped bars, the filling mechanism is used for filling the short steel bars or the short stripped bars into the temporary storage mechanism, the driving mechanism is used for driving the short steel bars or the short stripped bars at the discharge portof the temporary storage mechanism to carry out inserting motion in the direction crossing the stacking direction of a cement-based paste layer, and the driving mechanism inserts the short steel barsor the short stripped bars into an interlayer interface which at least crosses over two adjacent layers of cement-based paste layers printed by the 3D printing device. No printing gap exists betweenthe printed cement-based paste layers and the inserted steel bars, so that the connection tightness between cement paste and the steel bars is guaranteed, and the mechanical property and the toughnessof the interlayer interface of 3D printed cement-based material are really improved.
