Description

Flexible facing prefabricated part and forming method thereof
Technical Field

Background
A novel exterior wall decorative material appears in the existing market, the veneer effect is consistent with the texture of natural stone, but is different from the granite rigidity performance, and this kind of material can easily be crooked and tailor, can adapt to various curved surfaces and special-shaped surface structure, and crooked directness can reach 200mm, because flexible characteristic, when the precast concrete component is beaten the shaping instead, this ornamental material lay and cause aversion or leak thick liquid easily, lead to the veneer effect poor, influence the marketing of product.
There are two general methods for laying the flexible decorative material. One method is to apply the layer on the construction site by a single-sided adhesive method. The method does not need anchoring, namely, the back surface is coated with adhesive and directly adhered to the wall surface, the adhesive is compacted, and finally sealant is applied for pointing. However, in the method, due to secondary decoration, the adhesive is easy to age, the problem of durability between the product and the base layer cannot be solved, the product is easy to fall off, and in addition, the stability of the quality level is difficult to control in field construction, the construction quality is easy to be uncontrollable, although wet operation is avoided, the field operation still has great influence on the surrounding environment, high-altitude operation is required, and the safety risk is great.
Another approach is to prefabricate the flexible facing member. When the flexible facing component is prefabricated, a "reverse beating process" is generally preferred in a precast concrete component factory, that is, a decorative material (such as marble and ceramic tile) or a lining mold (such as a silica gel mold) with various decorative effects is firstly paved on a bottom mold in advance, so that the decorative layer of the wall is arranged below, and then concrete is poured. Compared with the decoration effect after on-site decoration, the 'reverse decoration process' realizes the one-step molding of the decoration surface and the component, does not need secondary decoration, and has smooth surface and firm adhesion. The problems of corrosion of metal pendants, falling of facing materials and the like can be solved, and the service life of the building is really the same as that of a building. However, in the existing forming method for the flexible facing prefabricated part, the phenomena of inaccurate positioning of facing materials, easy displacement of decorative materials and slurry leakage after concrete pouring still exist.
