Embodiment 1

[0046] Comply with the above technical solutions, such as Figure 1 ~ Figure 4 As shown, this embodiment provides a 3D printing concrete device for building automatic reinforcement, including a concrete sprinkler device 1, and the concrete sprinkler device 1 includes a sequentially connected material barrel 2, a mixing drum 3, and a feeding channel 4 and nozzle 5, also includes the reinforcement device 6 that is connected with concrete sprinkler device 1, and described reinforcement device 6 is connected with nozzle 5, is all provided with in the described barrel 2, mixing drum 3, feed channel 4 Stirring Conveyor 7.

[0047] The concrete enters the mixing drum 3, the feeding channel 4 and the nozzle 5 from the material barrel 2, and is evenly stirred in the material barrel 2, the mixing tube 3, and the material transferring channel 4, and then is sprayed out from the nozzle 5, and the reinforcement device 6 is used to give the printed Insert steel bars 30 into the concrete, a...

Embodiment 2

[0070] Comply with the above technical solutions, such as Figure 5 As shown, this embodiment provides a 3D printing concrete printing method for building automatic reinforcement, which is carried out by using the 3D printing concrete device for building automatic reinforcement described in Example 1.

[0071] Including the following steps:

[0072] Step 1: Pour the material components in the printed concrete into the barrel 2, and after being fully stirred evenly by the barrel 2, the mixing barrel 3 and the material transfer channel 4, extrude it from the specially designed nozzle 5 to form a long strip printing layer;

[0073] Step 2: While the nozzle 5 is extruding the printed concrete, the steel bar 30 has passed through the steel bar channel 11 of the wire extruder 10 to the beginning of the printing layer. Under the action of the connecting block 25, the nozzle device 1 and the reinforcement device 6 The whole moves toward the printing direction, so as to realize the a...

Abstract

The invention provides a 3D printing concrete device for building automatic reinforcement. The 3D printing concrete device comprises a concrete sprayer device, the concrete sprayer device comprises acharging barrel, a stirring barrel, a material conveying channel and a nozzle which are connected in sequence, the 3D printing concrete device further comprises a reinforcement device connected with the concrete sprayer device, and the reinforcement device is connected with the nozzle; and stirring and conveying devices are arranged in the charging barrel, the stirring barrel and the material conveying channel. By arranging the reinforcement device, steel bars are added in the concrete printing process, so that the tensile strength of a concrete printing component is enhanced; and conveying blades, stirring blades and conical rotating blades are sequentially arranged on a rotating rod, conical protruding parts which protrude outwards are arranged on the periphery of the inner wall of the material conveying channel, the conical protruding parts and the conical rotating blades are arranged in a staggered mode, under the combined action, printed concrete can be fully and evenly stirred, the rheological requirement of the printed concrete is met, and therefore blocking of a pipeline or the nozzle in the printing process is avoided.

Description

technical field [0001] The invention belongs to the technical field of 3D concrete printing in the construction industry, and relates to a 3D printing concrete device and method for building automatic reinforcement. Background technique [0002] The 3D concrete printing technology applied to the construction industry is an extrusion-based additive manufacturing technology, that is, the printable concrete is extruded through a nozzle to form a printing layer, and the layers are stacked on top of each other, and the layers are gradually formed without relying on a template. Compared with traditional concrete construction technology, it is not difficult to find that this printing technology not only has fast construction speed, but also has the ability to build complex geometric solid structures without templates, and can minimize material loss and labor costs. Advantage. [0003] However, a major challenge in bringing 3D concrete printing technology to practical use on a larg...
