Description
Technical Field
The invention relates to the technical field of 3D printing, in particular to the technical field of concrete 3D printing, and specifically relates to an intelligent basalt fiber composite concrete 3D printing device.
Background
3D printing is an advanced manufacturing technology, and has the advantage of no limitation of the structural shape of a product, so that the printing technology has wide application prospects in various fields. Successful application of 3D printing technology to the field of civil engineering has created a milestone-like revolution to the future construction industry.
At present, a 3D concrete printing technology mainly uses a 3D concrete printer to print and manufacture a certain single module of a building structure in a factory, and then transports the single module to a construction site for assembly. However, the conventional 3D printed concrete module is generally not provided with reinforcing bars inside, i.e., a non-reinforced concrete module. Because the concrete tensile strength that does not establish the reinforcing bar is lower, consequently 3D prints non-reinforced concrete and is used for non-load-bearing structure such as decorative wall more. The water-cement ratio is reduced, glass fiber is added, and the like, so that 3D printing concrete reinforcement treatment is realized, but the reinforcement measures have limited effect, and the manufacturing cost of the 3D printing concrete is greatly improved.
Therefore, scholars have attempted 3D printing of reinforced concrete. However, research and research have found that it is difficult to print the steel bars and the concrete simultaneously. At present, most methods for 3D printing of reinforced concrete are to manually pre-bind reinforcing steel bars, then to apply a 3D printing concrete mold, and then to pour ordinary cement concrete inside. However, this kind of 3D prints reinforced concrete concept has deviated from the characteristics of 3D printing intellectuality. Therefore, researchers also design that after the reinforcing steel bar is melted, a steel member which is not limited by the structure is printed by an extrusion device, but the mode destroys the original internal structure of the reinforcing steel bar, forms a plurality of hot melting defects, and is difficult to achieve the original service performance of the reinforcing steel bar; in addition, the steel bars need higher temperature for heating and melting, a large amount of energy is consumed, greenhouse gases are discharged, and the design concept of low carbon and environmental protection is not facilitated.
The basalt fiber raw material is taken from basalt stone, and has the advantages of wide raw material and simple production process. Compared with glass fiber, the basalt fiber has the characteristics of high strength and high modulus, and also has the advantages of high temperature resistance, oxidation resistance, radiation resistance, corrosion resistance, chemical stability and the like, so the basalt fiber is more energy-saving and environment-friendly in use. A great deal of research and application at present show that the tensile strength and the compressive strength of the concrete can be greatly improved by dispersing a certain amount of chopped basalt fibers in the concrete, and the durability and the long-term performance of the concrete can be effectively improved; meanwhile, the tensile strength of the basalt fiber composite bar with the same section is about 2 times of that of the traditional steel bar, and the required molding temperature in the production process of the basalt fiber composite bar is only about 100 ℃, which is far lower than the steel bar melting molding temperature, so that the basalt fiber composite bar has the advantages of safety and environmental protection. Therefore, the basalt fiber composite concrete is a good substitute for reinforced concrete, and intelligent 3D synchronous printing of the reinforcement and the concrete is easy to realize.
Therefore, the intelligent 3D printing device for basalt fiber composite concrete provided by the invention realizes synchronous intelligent printing of concrete and basalt fiber composite bars, overcomes the problem that the bars in the concrete cannot be intelligently printed in the technical field of 3D printing concrete at present, and can realize intelligent 3D printing of basalt fiber composite concrete.
