Spray nozzle for 3D printing concrete interlayer enhancement and concrete 3D printing equipment
The invention provides a 3D printing concrete interlayer reinforced nozzle and concrete 3D printing equipment. According to the 3D printing concrete interlayer reinforced nozzle, the outer surface of a base body can be wrapped with a reinforcing material while a 3D printing concrete base body material is extruded, the wrapping thickness of the reinforcing material is adjustable, the bonding strength of adjacent filaments in the horizontal direction can be improved while the interlayer bonding strength is improved, and then the overall mechanical property is improved. The problems that existing 3D printing concrete layers are insufficient in bonding strength, and printing cold joints are prone to occurring are solved. The concrete 3D printing equipment has wide applicability to different types of 3D printing concrete after using the 3D printing concrete interlayer reinforced nozzle provided by the invention, and has important significance in expanding the application of the 3D printing concrete in the building field.
本发明提供了一种3D打印混凝土层间增强的喷嘴及混凝土3D打印设备。本发明的3D打印混凝土层间增强的喷嘴能够在挤出3D打印混凝土基体材料的同时，使增强材料包裹在在基体外表面，且增强材料包裹的厚度可调，提高层间粘结强度的同时也能提高水平方向上相邻细丝的粘结强度，进而提高整体的力学性能。解决了现有3D打印混凝土层间粘结强度不足、容易出现打印冷缝的问题。本发明的混凝土3D打印设备使用了本发明提供的3D打印混凝土层间增强的喷嘴后，对不同种类的3D打印混凝土具有广泛的适用性，对于扩大3D打印混凝土在建筑领域的应用具有重要意义。
