Digital manufacturing method for light permeable concrete

Abstract

The invention discloses a digital manufacturing method for light permeable concrete. The method comprises the following steps that the density, array modes and patterns of optical fibers are designed through computer aided software; light guiding fibers are fixed to two optical fiber substrates in a penetrating-inserting mode through a braiding mechanism and a wire drawing mechanism, and different arrangement modes and separation distances of the optical fibers are achieved through stepping displacement of the two assembled optical fiber substrates; the optical fibers in certain lengths are reserved, the upper optical fiber substrate and the lower optical fiber substrate are separated after optical fiber arrangement is completed, and the near optical fibers are bonded into bundles through a binder so as to improve the mechanical strength of the optical fibers and protect the surfaces of the optical fibers; and the optical fiber substrates with the optical fibers arranged in advance are placed in a mold for concrete pouring and forming, and then cured to the demolding period, and the optical fiber substrates and the superfluous optical fibers are ground to obtain the light permeable concrete. The computer numerical control technology is firstly adopted for the optical fiber arrangement process of the light permeable concrete, and automatic rapid production of the light permeable concrete can be achieved.

Description

technical field [0001] The invention relates to concrete preparation technology, in particular to a digital manufacturing method for light-transmitting concrete. Background technique [0002] With the advancement of society and technology, the development of modern concrete not only develops towards the direction of high strength, high performance and harmony with the environment, but also architectural decorative concrete has become an important development direction of concrete. Architectural decorative concrete breaks the dull, bulky, bulky and monotonous feeling of traditional concrete, and becomes a light, lively, flexible and beautiful building material. In 2001, Hungarian architect Aron Losonczi introduced optical fiber-glass fiber [0003] A new type of building material is prepared by embedding concrete, and light travels from one side of the concrete to the other in optical fibers to form a transparent concrete. In 2010, more than 6,000 "transparent cement boards...

AI Technical Summary

Problems solved by technology

The optical fiber layout of the first three methods patents is subject to manual operation, with a large workload and low efficiency; 201210266298.1 reduces the workload of manual dispersion of optical fibers through electrostatic dispersion of optical fibers, but it is difficult to control the distance between optical fibers; 201510252516. In light concrete, the distance between optical fibers depends on the thickness of the grout. Pouring concrete after stacking a large number of grouted optical fiber bundles will greatly reduce the mechanical properties of light-transmitting concrete.

201110331500.X The light-transmitting concrete prepared by injecting resin into semi-hardened concrete is not suitable for the arrangement of optical fibers with high density. The resin expansion and contraction coefficient is large, which will easily lead to internal stress concentration of light-transmitting concrete, and its service performance is poor

In summary, the above patented methods all have certain technical feasibility. However, no patented method has been developed that can simultaneously take into account optical fiber layout, mechanical properties, and production efficiency in light-transmitting concrete.
