Technical Field

[0001] The invention relates to a method for imitating a clear water wall. Background Art

[0002] The exposed concrete wall is a typical historical style. At present, in order to restore the original historical style, the old bricks of the same period are mainly used in the repair and restoration process. In recent years, with the prohibition and restriction of the use of clay bricks, this kind of historical style repair process generally faces some problems such as material shortage, especially for large-scale style restoration projects, the problem is more prominent. At the same time, the use of traditional technology to restore the historical style of exposed concrete walls on a large scale also faces the problems of difficult to ensure the construction quality due to the lack of craftsmen and the loss of technology, and the large impact of wet operations on the construction site and the surrounding environment. In addition, with the increasing demand for digital cities, the application requirements of digital technologies such as artificial intelligence in the protection and repair of historical buildings are also rising.

[0003] At present, the industry has some research and accumulation on the prefabrication of blue and red bricks, but most of them are aimed at new buildings. It is difficult to restore the vicissitudes of the exposed concrete walls in historical buildings after years of use. In addition, the degree of digitization and intelligence in the entire prefabrication and restoration process is not high, so there is an urgent need for a method of imitating exposed concrete walls for large-scale reconstruction. Summary of the invention

[0013] Furthermore, in the above method, the masonry styles include: one straight and one tangent, plum blossom tangent, three straight and one tangent, and all straight.

[0014] Furthermore, in the above method, the color of the tile joints of the original surface after cleaning is intelligently identified, including:

[0015] Artificial intelligence and other technologies are used to complete intelligent recognition of brick surface color, forming a color spectrum of the surface to be imitated, and the color spectrum contains the value space of RGB values ​​of brick surface colors in different areas.

[0016] Furthermore, in the above method, a three-dimensional scan is performed on the dry wall to be imitated to obtain the size information of the dry wall to be imitated, and a design drawing of the imitated wall surface is obtained based on the size information of the dry wall to be imitated, including:

[0017] First, use 3D scanning technology to complete the overall scanning of the dry-concrete wall to be imitated, and obtain the length, width and thickness of the entire wall and the size specifications of the detailed fancy structure. If the dry-concrete wall has a waistline, the information to be obtained includes the height, thickness and length of the entire wall, and the height, thickness, length and position information of the waistline;

[0027] Furthermore, in the above method, pouring concrete on the surface of the internal and external admixtures of the mold to form the imitation component includes:

[0028] During the concrete pouring process, it should be vibrated while pouring to ensure that the concrete slurry fits fully with the mold to prevent the formation of bubbles, honeycombs and rough surfaces.

[0029] Furthermore, in the above method, after pouring concrete on the surface of the internal and external admixtures of the mold to form the imitation component, the method further includes:

[0030] After the concrete is poured, it is cured, and the curing time is generally 7-14 days. During the curing period, the temperature must be between 5℃ and 35℃, and the humidity must be above 95%. During the curing period, avoid heavy collisions, trampling and violent vibrations to avoid damage to the concrete. At the same time, pay attention to avoid direct sunlight and excessive wind to prevent cracking of the concrete surface and excessive evaporation of water.

[0031] Before formally removing the formwork, conduct a trial formwork removal to ensure that the formwork is detached from the concrete surface, and do not knock it hard; the removed formwork should be cleaned promptly and coated with release agent and covered for protection.

[0032] Furthermore, in the above method, based on the color of the tile joints of the original facing surface after cleaning, a multi-layer color rubbing treatment is performed on the facing surface of the imitation component after demolding, including:

[0033] Before applying multiple layers of paint, the finishing layer should be cleaned first to remove pollutants and impurities on the surface to ensure the flatness and smoothness of the base surface;

[0034] The corresponding pigments are prepared according to the color spectrum classification, and the order of multi-layer color rubbing of the finishing is determined in combination with the specifications of the finishing;

[0035] According to the color spectrum and the order of color rubbing, the multi-layer color rubbing of the imitation finish is completed, and the color rubbing process is performed layer by layer. After the color of the previous layer of finish meets the requirements, the next step of color rubbing is performed. The color should be applied evenly during the process to avoid obvious brush marks;

[0036] After the surface color rubbing reaches the expected effect, apply the surface protective agent to ensure that the durability of the wall will not decrease due to water leakage during use.

[0037] Compared with the prior art, the present invention is based on digital technical means such as artificial intelligence to automatically identify the masonry form and brick surface color of the exposed brick wall, form a color spectrum of the exposed brick wall finish, and form a suitable mold based on technologies such as 3D printing. Through the multi-layer color rubbing process of the finish, the "original" restoration of the exposed brick wall finish with concrete materials is carried out based on the prefabrication process. It can not only effectively solve the problems of the need to improve the construction quality of the traditional repair process due to the interruption of craftsmen and the loss of craftsmanship, but also effectively improve the performance of the finish and the green and low-carbon level of the implementation process, and at the same time provide a new solution for the restoration of historical finishes.

[0038] The present invention uses artificial intelligence and other modern technologies to automatically identify the original wall masonry form and brick color, and simultaneously completes the intelligent arrangement of the new wall masonry form. It uses 3D printing technology to form a suitable decorative imitation mold, and based on the prefabrication concept and multi-level color matching technology, it completes the efficient restoration of various types of clear water wall finishes, which can effectively improve the effectiveness of the implementation process, ensure the construction quality, and achieve precise control of the finishing effect and effective improvement of performance.

[0039] The present invention has obvious advantages in reducing costs and increasing efficiency, which is mainly reflected in that it first uses modern technologies such as artificial intelligence to complete the intelligent recognition of the original wall masonry form, avoiding the uncertainty of manual recognition, and realizes automatic recognition of the original wall color based on image recognition and other technologies, thereby improving the accuracy and efficiency of the restoration of the finish, and uses 3D printing technology to form a suitable mold, avoiding the waste of traditional templates.

[0040] The present invention can complete the accurate and efficient restoration of various types of clear water wall finishes based on the prefabrication concept and multi-level color rubbing technology. The whole implementation process has a high degree of factory operation and obvious green and environmental protection advantages.
