Description

Technical Field

[0001] The invention relates to the field of building materials, and in particular to a method for manufacturing light-transmitting concrete. Background Art

[0002] Translucent concrete is composed of light-conducting fibers and concrete. The content of light-conducting fibers in translucent concrete is small, which will not affect the load-bearing structure and has no negative impact on the strength of concrete. The combination of concrete and light-conducting fibers can show a translucent and opaque decorative effect. After the light-conducting fibers are translucent, some specific patterns can be formed, which can form a good decoration. It has been widely used in architectural decoration.

[0003] In the traditional production of translucent concrete, only optical fibers with a diameter greater than 1 mm can be used. The optical fibers are manually inserted and fixed in the concrete mold, leaving a certain gap between the optical fibers so that the concrete can flow and fill. The concrete is then poured, and the translucent concrete is obtained after the concrete solidifies. The optical fibers can also be inserted into the concrete mold to form various patterns, so that the translucent concrete will show some specific pattern effects when the light is transmitted. However, there are some problems with the existing manually inserted and fixed optical fibers: 1. The fixing efficiency is slow and cannot meet the needs of large-scale production; 2. When making a specific pattern, the fixing position of the optical fiber is not accurate, and the pattern effect displayed by the translucent concrete when the light is transmitted is not clear, and the visual effect is not good. Summary of the invention

[0004] The object of the present invention is to provide a method for manufacturing light-transmitting concrete, so as to solve the problems of low fixing efficiency of light-guiding fibers and inaccurate fixing position of light-guiding fibers in the existing light-transmitting concrete.

[0005] In order to solve the above technical problems, the method and technical means of manufacturing light-transmitting concrete adopted by the present invention are as follows: comprising a 3D printing plug and a fixed pad installed in a concrete mold; the 3D printing plug comprises a push rod, a feed box, a fixed guide cylinder, a reset mechanism and a telescopic guide cylinder, the push rod pushes the light guide fiber in the feed box out of the fixed guide cylinder and the telescopic guide cylinder in sequence, and inserts the light guide fiber on the fixed pad, and the reset mechanism resets the telescopic guide cylinder to the initial position during the withdrawal of the push rod;

[0006] The specific method is as follows:

[0007] A. Decompose the pattern to obtain fixed points, and determine the moving route of the 3D printed plug based on the fixed points: According to the pattern that needs to be customized for the light-transmitting concrete, decompose the pattern into several pixel points, determine the position of the fixed points of the light-guide fiber, and design the moving sequence of the fixed points of the light-guide fiber to determine the moving route of the 3D printed plug;

[0008] B. The 3D printed plug moves to the initial position: the 3D printed plug moves to the top of the first fixed point, and the distance from the fixed pad is less than 5 cm when the telescopic guide cylinder is extended to the longest stroke;

[0009] C. Insert the optical fiber at the first fixed point: the push rod moves downward and pushes the optical fiber into the fixed guide cylinder when it reaches the feed box. When the push rod reaches the fixed guide cylinder, the push rod continues to move downward and pushes the telescopic guide cylinder to extend until the telescopic guide cylinder is fully extended. At this time, the telescopic guide cylinder fits the fixed pad, and the push rod pushes the optical fiber into the fixed pad to complete the fixation of the optical fiber at one fixed point. Then the push rod returns to the top of the first fixed point, and the telescopic guide cylinder returns to the initial position under the action of the reset mechanism.

[0010] D. Insert the optical fiber at the second fixed point: The 3D printed plug moves horizontally to the top of the second fixed point under the action of the moving mechanism, repeats the insertion process of the optical fiber at the first fixed point, completes the insertion of the optical fiber at the second fixed point, and then the 3D printed plug returns to the top of the second fixed point;

[0011] E. Complete the fixation of all the fixed points: insert and fix the optical fibers of all the fixed points in the order of their movement, and then return the 3D printed plug to the top of the last fixed point;

[0012] F. Pouring concrete to produce translucent concrete: remove the fixed light-guiding fiber concrete mold, pour concrete into the concrete mold, put the entire translucent concrete and the mold into a drying room, dry the translucent concrete, and after the translucent concrete is completely solidified, remove the mold and take out the translucent concrete, cut off and grind off the leaked light-guiding fiber, and then grind and polish to obtain the translucent concrete.

[0013] The method for manufacturing light-transmitting concrete of the above technical scheme has the following technical advantages: the present invention adopts the method of inserting the light-guiding fiber into the fixed pad by a pushing and inserting rod, and when the pushing and inserting rod enters the feed box, the light-guiding fiber is pushed into the fixed guide cylinder until the light-guiding fiber extends out of the fixed guide cylinder for a certain distance, and then the pushing and inserting rod drives the telescopic guide cylinder to extend, and drives the telescopic push rod to move the telescopic guide cylinder and the light-guiding fiber downward, and when the telescopic guide cylinder is at the maximum telescopic stroke, the telescopic guide cylinder contacts the fixed pad, and at this time, the light-guiding fiber is inserted into the fixed pad under the pushing action of the pushing and inserting rod; during the entire process of inserting the light-guiding fiber, the telescopic guide cylinder serves as an insertion guide for the light-guiding fiber, and when the light-guiding fiber is pushed by the pushing and inserting rod, the light-guiding fiber The force is more uniform under the action of force, ensuring that the light guide fiber is inserted vertically relative to the fixed pad when inserted, making the light guide fiber more vertical when inserted, and at the same time, during the process of upward recovery of the 3D printing plug, the telescopic guide cylinder is always perpendicular to the fixed pad, and can also play a certain positioning and straightening role on the light guide fiber during the recovery of the 3D printing plug; the present invention has the guidance of the telescopic guide cylinder when inserting the light guide fiber, and the force is more concentrated during the process of inserting the light guide fiber into the fixed pad, which is more conducive to inserting the fixed pad. At the same time, the light guide fiber will not undergo a large deformation, ensuring that the light guide fiber is vertically inserted into the fixed pad, making the light guide fiber more vertical to the fixed pad, and the effect is better after pouring concrete.

[0014] As a preferred solution, the push rod inserts the optical fiber through the fixing pad by more than 1 mm; the deeper the push rod inserts the optical fiber into the fixing pad, the more secure the fixation of the optical fiber.

[0015] As a preferred solution, a limit portion is provided at the lower end of the fixed guide cylinder for limiting the telescopic guide cylinder when it is telescoped to the longest stroke, and preventing the telescopic guide cylinder from sliding off the fixed guide cylinder.

[0016] As a preferred solution, the reset mechanism is a combination of a spring, a rubber rope, a spring sheet and a steel wire rope, etc.; the reset mechanism makes the telescopic guide cylinder reset more sensitively, and the reset mechanism is easy to install and has a low cost.

[0017] As a preferred embodiment, the push rod includes a push head and a push rod, the push head is provided with a protrusion at the end close to the push rod, and the length of the push head is greater than the depth of inserting the optical fiber; the feed box and the fixed guide cylinder are provided with a sliding groove that cooperates with the protrusion of the push head of the push rod; this is conducive to ensuring that the push rod is more stable when sliding on the feed box and the fixed guide cylinder.

[0018] As a preferred embodiment, the lowermost end of the telescopic guide cylinder is conical, which reduces the resistance of the telescopic guide cylinder when it goes downward, and at the same time reduces the resistance between the telescopic guide cylinder and the fixed pad after the telescopic guide cylinder contacts the fixed pad, making it easier to pull out the fixed pad when the telescopic guide cylinder is retracted, preventing the fixed pad from moving.

[0019] As a preferred solution, the fixing pad is a foam board, clay or plasticine; the material source of the fixing pad is easy to obtain, the cost is low, and it is easy to be penetrated by the light-guiding fiber, so it is easy to fix the light-guiding fiber. BRIEF DESCRIPTION OF THE DRAWINGS
