Mechanical interlocking and wetting filling composite enhanced 3D collaborative printing nozzle and system
The invention provides a mechanical interlocking and wetting filling composite enhanced 3D collaborative printing nozzle and system. The sawtooth structure formed by extrusion molding of a concrete base material is added, the sawtooth structure forms grooves in the interlayer surface after a certain time interval, sites are provided for a reinforcing material, meanwhile, the sawtooth structure is beneficial to mechanical locking connection of an interface, and compared with a common collaborative printing nozzle, the collaborative printing nozzle has the advantages that the efficiency is high; through composite reinforcement, the 3D printing concrete base material has higher interlayer bonding strength, reinforcing material notches also form corresponding sawtooth extrusion openings, the use amount of the reinforcing material is more convenient to control, and the constructable performance of the reinforcing material is effectively improved. According to the method, the applicability of the interlayer reinforced concrete is expanded, and the method has important significance in promoting the practical application of the 3D printing concrete.
本发明提供了一种机械互锁和润湿填充复合增强的3D协同打印喷嘴及系统。本发明通过增加混凝土基体材料挤出成型的锯齿结构，在一定时间间隔后锯齿结构在层间表面形成凹槽，为增强材料提供位点，同时锯齿结构有利于界面的机械锁连，相比于普通协同打印喷嘴，复合增强使3D打印混凝土基体材料具有更高的层间粘结强度，增强材料槽口也组成对应锯齿挤出口，更便于控制增强材料的用量，有效提高了增强材料的可建造性能。本发明扩大了层间增强混凝土的适用性并对推进3D打印混凝土的实际应用具有重要意义。
