Manufacturing method and manufacturing device of light-transmitting concrete block

Abstract

The invention belongs to the technical field of building materials and particularly relates to a manufacturing method and a manufacturing device of a light-transmitting concrete block. The manufacturing method of the light-transmitting concrete block is characterized by comprising the following steps: (1), preparing the manufacturing device of the light-transmitting concrete block; (2), arranging optical fibers; (3) moulding concrete through casting: separating a moulding groove and a preparing groove; and then pouring concrete slurry in the moulding groove to perform vibration moulding; and (4) performing demoulding and cutting on concrete: demoluding hardened concrete from the moulding groove, cutting the concrete to the assigned thickness along the arrangement direction of the optical fibers so as to obtain the light-transmitting concrete block. The characteristics in the invention are that the optical fibers can be arranged fast and conveniently, the light-transmitting concrete block can be manufactured fast and can adopt a continuous manufacturing mode, and the utilization rate of the optical fibers is high, therefore, the industrialized production of the light-transmitting concrete block can be performed.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a method for preparing a light-transmitting concrete block and a preparation device thereof. Background technique [0002] The reason why concrete can transmit light is that the optical fibers between the two planes of the concrete are placed in parallel in a matrix, and the light passes through the optical fibers from one side of the concrete to the other in a point-like manner. Light-transmitting concrete can be used to make garden architectural products, decorative plates, decorative blocks and curved surfaces, which provides the possibility of realizing the artistic imagination and creation of architects. [0003] In 2001, Hungarian architect Aron Losonczi first proposed the concept of light-transmitting concrete, and successfully developed light-transmitting concrete (LiTraCon) in 2003 using light glass fibers. However, the interior of the concrete is ...

Problems solved by technology

[0003] In 2001, Hungarian architect Aron Losonczi first proposed the concept of light-transmitting concrete, and successfully developed light-transmitting concrete (LiTraCon) in 2003 using light glass fibers. However, the interior of the concrete is a highly alkaline environment, and light glass fibers are in Erosion is prone to occur in this environment, which affects the long-term light-conducting properties of light-transmitting concrete, and because the quartz optical fiber he uses is thin and soft, it is difficult to achieve a smooth surface and difficult to lay out. Low

Chinese patent 201110021994.1 provides a method of preparing cement-based light-transmitting materials by using the parallel arrangement of optical fibers. The method is to first pour a layer of cement paste, then tile the optical fiber, then pour a layer of cement paste, and then tile the optical fiber. Repeat this until the test mold is completely filled with cement slurry and optical fiber. This method is difficult to control the thickness of the cement slurry when laying the optical fiber each time, and the resulting concrete is prone to uneven spacing of the light-transmitting layer; and layer by layer The operation of pouring cement paste and laying optical fibers is cumbersome, time-consuming and labor-intensive, and it is difficult to realize large-scale industrial production

Chinese patent 200710007521.X provides a light-transmitting concrete production module and its rapid production method, which can directly form light-transmitting concrete of different sizes according to different design requirements, but this method needs to fix the conduction unit on the top form and multiple Between the bottom form, when it is necessary to produce light-transmitting concrete with a high light transmittance, the number of light transmission units will be large, and the workload of regularly fixing a large number of light transmission units between the top form and multiple bottom forms is relatively large. The bottom mold is a formwork with holes. When the light transmission unit is fixed, the holes in the bottom mold cannot be completely closed. After the concrete is poured, there may be grout leakage; in addition, in the light-transmitting concrete Among the raw materials, optical fiber is the most expensive raw material, but in this method, there are a large number of optical fibers between adjacent bottom molds, and they are not used to prepare in the light-transmitting concrete unit, that is, the fiber utilization rate of this method is low and the cost is high

[0005] In summary, the preparation method of the above-mentioned light-transmitting concrete has problems such as a large workload for arranging optical fibers, complex and slow preparation process of light-transmitting concrete, low utilization rate of optical fibers, and difficulty in large-scale industrial production.
