Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated light-transmitting wall formwork, and specifically relates to a 3D-printed prefabricated light-transmitting wall formwork. Background Art

[0002] With the development of intelligent building technology, people have an increasing demand for functional building materials. Translucent cement-based composite materials are one of the important development directions of wall materials in the field of building energy conservation, which can make concrete building structures have both mechanical performance bearing, light transmission and decorative effects. In addition, the combination of translucent cement-based composite materials and display technology can protect the regional architectural style while also having information display functions, which has significant social and economic benefits. The high-efficiency and diversified preparation technology of translucent cement-based composite materials has become an important research and development direction in the field of functional building materials.

[0003] The document "Lin Jianjian, Shen Jianxing. Research Progress of Transparent Ceramics. Journal of Shandong Institute of Light Industry, 2009, 23(3): 5-11" mentioned that in 1955, Burke and Coble of the General Electric Company Research Institute in northern New York, USA, began to study transparent ceramics. In 1959, they fired translucent alumina ceramics, breaking the traditional concept of "ceramics are opaque" and opening up a new field for the development of ceramic materials. In 2001, Hungarian architect Aron Losonczi first proposed the concept of transparent cement-based materials, and in 2003, he successfully developed translucent cement using ordinary optical fibers.

[0004] Chinese patent 201210266298.1 provides a method for preparing light-transmitting concrete by applying electrostatic force to a fiber bundle with an electrostatic emitter, dispersing the fiber bundle and then inserting it into a quick-setting slurry and letting it stand until the quick-setting slurry is finally set. The method is simple to operate and has high efficiency. It can realize on-site pouring of light-transmitting concrete, but the method cannot achieve accurate positioning of size distribution and position.

[0005] Chinese Patent 201710308930.7 discloses a 3D printing preparation method for a light-transmitting cement-based composite material. The casting plate of the optical fiber column is directly printed out by 3D printing. The light-transmitting column array of the method has strong independent design, high dimensional consistency and precise and adjustable position. The optical fiber arrangement process is complex and the position accuracy is improved. In order to ensure that the erected optical fiber has sufficient stability during the casting process, the substrate of the casting plate needs to be thick enough to support the optical fiber. However, it takes a long time to grind the very thick substrate during demoulding and grinding, which is very cumbersome in the actual processing and production process, thus wasting time and effort. Utility Model Content

[0006] This paper proposes a 3D printed prefabricated light-transmitting wall template. The template is provided with a base and a plurality of fiber optic columns through 3D printing. A plurality of fiber optic columns are provided above the base. The base and the fiber optic columns are connected by a disassembly shrink column. The upper and lower ends of the disassembly shrink column are wide diameters, and the center of the disassembly shrink column is a narrow diameter. One end of the disassembly shrink column is connected to the top surface of the base, and the other end of the disassembly shrink column is connected to the bottom surface of the fiber optic column. A casting partition is provided on the outer side of the end surface where the disassembly shrink column is connected to the fiber optic column. The top surface of the casting partition is flush with the end surface of the disassembly shrink column. The substrate after casting can be quickly and conveniently removed by disassembling the shrink column, thereby eliminating the need to grind the heavy substrate, greatly improving the production efficiency. In addition, the special casting partition can not only play a double-layer fixing role for the fiber optic column, but also can be polished more conveniently later.

[0007] The base is in the shape of a rectangular thin plate and is made by 3D printing. A disassembly column is embedded inside the base and a cast partition is provided on the top of the base. Because the optical fiber column is fixed in the form of a double-layer plate, there is no need to use a thick base, and the optical fiber column can be fixed. This not only saves 3D printing materials, but also improves the efficiency of 3D printing.

[0008] The dismantling shrinkage column is shaped as an hourglass-shaped cylinder. It is vertically arranged above the base. The outer side of the bottom end of the dismantling shrinkage column is connected to the inside of the base, and the outer side of the top end of the dismantling shrinkage column is connected to the inside of the casting partition. The narrow diameter in the middle of the dismantling shrinkage column can be used to quickly break the casting partition and the base, which is convenient and greatly improves the efficiency of labor.

[0009] The casting partition is in the shape of a rectangular thin plate, and a number of disassembly shrinkage columns are provided through the middle of the casting partition. The casting partition is produced by 3D printing. By casting directly on the top of the casting partition, the shrinkage columns can be disassembled after the base is separated. Only a thin layer of the casting partition needs to be quickly and conveniently polished to quickly obtain the finished product, which is efficient and convenient.

[0010] The optical fiber column is cylindrical in shape, and its diameter is equal to the top diameter of the dismantled shrinkage column. The vertical center of the optical fiber column is aligned with the center of the dismantled shrinkage column. The optical fiber column is directly connected to the dismantled shrinkage column so that the optical fiber column can be stably placed vertically above to ensure the stability of the optical fiber column after casting.

[0011] The base, disassembled shrinkage column, cast partition and optical fiber column are all made through 3D printing one-piece molding process. The 3D printing one-piece molding method can quickly and efficiently combine a variety of different materials and print out the desired shape, which greatly reduces the production cost of the template and improves production efficiency.

[0012] Beneficial effects:

[0013] By disassembling the shrink column, the substrate after casting can be removed quickly and conveniently, eliminating the need to grind the heavy substrate, greatly improving production efficiency. The special casting partition can not only fix the optical fiber column in double layers, but also facilitate subsequent grinding.

[0014] Because the optical fiber column is fixed in the form of a double-layer plate, there is no need to use a thick base to fix the optical fiber column. This not only saves 3D printing materials, but also improves the efficiency of 3D printing.

[0015] By dismantling the narrow diameter in the middle of the shrink column, the cast partition can be quickly separated from the base, which is convenient and greatly improves the efficiency of labor.

[0016] By pouring directly on top of the casting partition, the shrink column can be disassembled after the base is separated. Only a thin layer of the casting partition needs to be quickly and conveniently polished to quickly obtain the finished product, which is efficient and convenient.

[0017] The optical fiber column is directly connected to the dismantled shrink column, so that the optical fiber column can be stably vertically arranged above, ensuring the stability of the optical fiber column after pouring.

[0018] The one-piece 3D printing method can quickly and efficiently combine a variety of different materials and print the desired shape, greatly reducing the production cost of the template and improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
