In the method of adopting the hanging plate, the hanging plate has the advantages of light weight, convenient cleaning, difficult fading, difficult erosion, ultraviolet resistance, aging resistance, static resistance and the like, and the decorative exterior wall hanging plate is increasingly applied to building decoration at present.
However, in the existing hanging plate, the colors and the types are monotonous, the number of joints is large, the construction efficiency is low, and the overall effect change of the building is small. Meanwhile, in the prior art, the exterior facing of the building is mainly decorated by mushroom stones, multi-layer stones or rubble and granite plates. However, with the increasing improvement of the living standard of people, the enhancement of environmental protection, energy conservation and natural resource protection consciousness, the original decorative material is the exterior wall decorative material which is monotonous in variety and similar in application of a plurality of buildings, the visual characteristics of the whole space are given to people, the unique cultural smell and the historical feeling are lacked, and the innovative architectural decorative style and style are not provided. More importantly, the materials need a large amount of applied stones, and limited resources are required to be searched for from the natural environment in a large scale, which is contrary to the guiding idea of realizing circular economy and fully, reasonably and scientifically utilizing natural resources advocated by the current society.
Meanwhile, the dimension of the hanging plate is also determined by the material property of the stone. If granite is adoptedStone material of which the specification cannot be larger than 1m2This undoubtedly will consume a large amount of steel when the installation, decorate the effect that comes out moreover fragmentary, not to say more certainly panel of granite class is on the surface course color, hardly guarantees that the ore body colour of mine is unanimous mutually, the color line is unified mutually.
Although the exterior wall decoration hanging plate in the prior art is also made of concrete, the surface of the plate needs to be subjected to acid etching or burning, the environment is polluted, the dead weight of the plate is 3 times of that of the reconstructed stone decoration concrete exterior wall hanging plate, the installation of the hanging plate is directly influenced, and the requirement on the installed back hanging steel is higher. Meanwhile, the decoration of high-rise buildings is not facilitated.
If the integral wall board is adopted, the surface is smooth, the thickness is equivalent to the thickness of a wall body, the weight is large, the self weight is dozens of times of the weight of the reconstructed stone decorative concrete exterior wall hanging board, and the wall board is only suitable for steel skeleton buildings.
In the prior art, in the utility model with the patent application number of 200320119804 and the name of invention of sandstone cement building decoration member, the following technical problems exist in the structure and the manufacturing process:

In the aspect of installation, due to the adoption of a prefabricating method, the installation embedded part can be preset during manufacturing, so that the problem that a groove for placing a dry hanging part is cut on a granite plate with the thickness of 18mm, and the groove is easy to break under the condition of external force is solved. And further, atmospheric noise pollution and dust pollution on the construction site are avoided.
The recycled stone decorative concrete exterior wall cladding is characterized in that a steel reinforcement framework and an alkali-resistant glass fiber mesh are embedded in advance when a structural layer is manufactured, even under the impact of external force, when the cladding is damaged, only destructive cracks occur, the phenomenon that a granite plate is cracked and falls is avoided, although some engineering of marble also uses glass fiber reinforced plastics to glue a layer of common mesh behind the plate when the plate is installed, the ageing phenomenon of an organic resin layer for a long time is easy to occur, the bonding effect is lost, and the function of preventing fragments from falling is not achieved.
The manufacture of the reconstructed stone decorative concrete exterior wall cladding adopts prefabrication, so that the internal and external corners formed by buildings can be manufactured in production, and the decorative effect which is difficult to realize by granite plates is solved.
When the stone recycled decorative concrete exterior wall cladding is manufactured, as the aggregate selection of the decorative layer concrete is not limited by mineral resources, industrial waste (stone powder) can be fully digested for proportioning, further the exploitation is reduced, and the mountain-opening waste and the stone carving waste are converted into raw materials, so that natural resources are protected to the maximum extent, and limited mineral resources are reasonably utilized. The manufacture of the reconstructed stone decorative concrete exterior wall cladding structure layer can also consume a large amount of various stone powders, the color and luster of the stone powder are not limited, and the stone powders accumulated for a long time can be changed into valuable. A large amount of stone powder is consumed, so that natural resources are effectively utilized, and the pollution of dust to the environment is prevented, thereby realizing the environment-friendly industry. The granite plates are widely used for decorating buildings, so that the natural resources need to be preferentially exploited, more than 30 percent of resource waste and environmental pollution of different degrees are caused, and natural vegetation and ecological natural balance can be damaged.
