Anti-seepage color-developing face brick for building outer wall decoration

Abstract

The invention discloses an anti-seepage color-developing face brick for building outer wall decoration, and belongs to the technical field of outer wall face bricks. A hollow heat preservation sleeveis arranged between an inner brick body and an outer decoration brick body, the hollow heat preservation sleeve is wrapped with a layer of arc-shaped waterproof sleeve, and through layer-by-layer embedded connection, the preliminary heat preservation and waterproof effects are achieved; a plurality of water absorption cavities are formed between the hollow heat preservation sleeve and the outer decoration brick body, and water absorption flow guide columns are embedded in the water absorption cavities; when the outer wall of the outer decoration brick body is damaged and rainwater seeps in, water absorption layers filling the water absorption flow guide columns gather and adsorb the rainwater, and water is guided into flow guide holes of the water absorption flow guide columns; the rainwater is guided downwards through the water absorption flow guide columns arranged in the vertical direction and guided out through water dripping openings, and meanwhile part of the rainwater seeps in and flows back to color-developing columns; and color-developing rods are embedded in the inner sides of the backflow color-developing columns, the color-developing rods develop colors when encountering water, thus proving that the face brick at the position is damaged and seeps in water, and a good safety warning effect is achieved.

Description

Technical field[0001]The invention relates to the technical field of exterior wall tiles, and more specifically to an impermeable and color-developing tile for exterior wall decoration of buildings.Background technique[0002]With the improvement of people's living standards, people have higher and higher requirements for the aesthetics of buildings. Many exterior decorations of buildings use exterior wall tiles to decorate the appearance of buildings. Exterior wall tiles have the advantages of beautiful appearance and durability. Among them, the anti-leakage of the surface bricks has also become an important aspect that affects the function of the building.[0003]In the existing environment, one of the main reasons for external wall water seepage is that concrete and brick masonry are two different materials with different temperature linear expansion coefficients. Under the same temperature difference, cracks are easily generated at the joints of the wall bricks. Rainwater penetrates...

AI Technical Summary

Problems solved by technology

Under the same temperature difference, cracks are likely to occur at the joints of the wall bricks, and rainwater penetrates into the wall along the cracks of the bricks and the brick surface. Under the capillary action of the capillary pores between the bricks, it gradually penetrates towards the wall, which will damage the wall over time and have a negative impact on the building; A layer of waterproof material, but when the outside of the brick body is broken, rainwater can still seep into the wall through the gap, and the water seepage phenomenon of the small area of ​​the wall is generally not easy to detect, and there will be certain safety hazards over time
