Prefabricated heat-insulation bare concrete decorating plate and manufacturing method

Abstract

The invention provides a prefabricated heat-insulation bare concrete decorating plate and a manufacturing method. The prefabricated heat-insulation bare concrete decorating plate comprises a decorating plate body, wherein the decorating plate body is formed by bare concrete prefabrication; a first heat-insulation plate and a second heat-insulation plate are pre-buried in the decorating plate body;multiple first through holes are formed in the first heat-insulation plate; at least two rows and two columns of first through holes are formed and uniformly distributed in the first heat-insulationplate; the second heat-insulation plate and the first heat-insulation plate are symmetrically arranged; and second through holes staggered with the first through holes in the first heat-insulation plate are formed in the second heat-insulation plate. The two symmetrically arranged heat-insulation plates are pre-buried in the decorating plate body, and the through holes are formed in the heat-insulation plates in a staggered way, so that the strength of the decorating plate is ensured, and meanwhile, a heat insulation function is realized; and through the design of a bell and spigot joint, theconnecting strength of adjacent prefabricated heat-insulation bare concrete decorating plates is ensured.

Description

technical field [0001] The invention belongs to the technical field of industrial and civil construction, and in particular relates to a prefabricated thermal insulation fair-faced concrete decorative board and a manufacturing method thereof. Background technique [0002] Fair-faced concrete (Architectural concrete, fair-faced concrete) is a kind of expression technique of architectural modernism, and it is also called decorative concrete because of its great decorative effect. The basic idea is that after the concrete is poured, there is no longer any painting, tiles, stones and other materials, which is a way of expressing the concrete without makeup. [0003] Prefabricated fair-faced concrete decorative panels are developed based on fair-faced concrete, and prefabricated fair-faced concrete decorative panels are pasted on the outside of ordinary buildings. Prefabricated fair-faced concrete decorative panels on the market are generally prefabricated from pure concrete and ...

Problems solved by technology

[0003] Prefabricated fair-faced concrete decorative panels are developed based on fair-faced concrete, and prefabricated fair-faced concrete decorative panels are pasted on the outside of ordinary buildings. Prefabricated fair-faced concrete decorative panels on the market are generally prefabricated from pure concrete and directly pasted on the exterior walls of buildings. , it is no longer possible to insulate the outer wall. If it is pasted on the outside of the insulation layer, the strength of the paste is difficult to guarantee, and there is a safety hazard of falling down. Therefore, it is currently a technical problem to be solved to invent a prefabricated fair-faced concrete decorative panel with thermal insulation.
