Description

Technical Field

[0001] This invention belongs to the field of architectural decoration engineering technology, specifically relating to a flexible dry-hanging structure and installation method for building exterior wall decorative panels that is simple in structure, has high positioning accuracy, does not damage the panels, has reliable connection, and high installation efficiency. Background Technology

[0002] To beautify and protect buildings, modern building exterior decoration often employs techniques such as paint application, tile installation, and stone cladding. Generally speaking, for exterior wall decoration with concrete and brickwork as the base, considering factors such as project cost, technical complexity, and decoration level, paint application is relatively common, stone cladding is more upscale, and tile installation is in the middle. Among these, tiles offer strong decorative appeal, good durability, and are easy to clean, making them suitable for various public and residential buildings and widely used in the construction engineering field.

[0003] If we categorize exterior wall tiles by size: small ones are called mosaic tiles, and large ones are called facing tiles. Currently, the common construction method is to use cement mortar to adhere them to the building's exterior wall substrate, which is considered a wet construction method. While there are specific technical standards and architectural design regulations for cement mortar installation, the following factors objectively exist: First, the working environment of building exterior walls is complex, facing the influence of natural factors such as wind, sun, rain, seasonal changes, and air pollution, leading to thermal expansion and contraction, and pollution erosion, which can easily cause cracking and peeling. Second, the installation quality is affected by the flatness and humidity of the exterior wall substrate, as well as the quality of the finished tiles, which can easily lead to insufficient bonding strength, deformation, or even detachment. Third, factors such as worker skill, inaccurate cement mortar ratios, uneven application thickness, and insufficient fullness can affect the mortar's bonding strength, resulting in hollow areas, voids, shrinkage cracks, and ultimately, detachment. Due to these subjective and objective factors, the durability of tiled buildings is reduced, and their quality is difficult to guarantee effectively. In response, relevant management departments have issued technical regulations prohibiting the use of cement mortar for bonding exterior wall tiles.

[0004] To address the shortcomings of the cement mortar bonding method, a dry-hanging construction process for exterior wall decorative panels has emerged. This process uses a steel structure as the framework, with the decorative panels fixed to the framework using angle steel, brackets, connectors, and bolts for rapid installation. The dry-hanging method is widely used due to its simplicity and convenience, significantly improving construction efficiency. However, existing dry-hanging structures are relatively complex, requiring each bolt to be individually secured, making construction cumbersome and resulting in a long installation period. Furthermore, any improper installation step can lead to safety hazards such as cracking and detachment of the decorative panels. To address this, existing technologies include methods such as setting upward-sloping slots on the back surface of decorative panels and correspondingly installing dry-hanging devices with upward-sloping support plates on the external wall keel, thereby fixing the decorative panels by inserting them downward-slopingly onto the support plates; and embedding dry-hanging components into the back surface of the decorative panels and fixing connecting profiles with dry-hanging holes on the wall keel, with the decorative panels being fixed by hanging or inserting the dry-hanging components into the dry-hanging holes of the connecting profiles. Although the aforementioned methods are relatively simple in terms of dry-hanging structure and construction and have high construction efficiency, they require decorative panels with special structures or require drilling holes in the decorative panels, which reduces the strength of the panels and shortens their lifespan. Moreover, the hanging or inserting structure makes the decorative panels prone to shaking or even falling off in windy weather, resulting in insufficient reliability. Summary of the Invention

[0005] To overcome the shortcomings of the above-mentioned building exterior wall decorative panel installation structures and methods, based on the traditional exterior wall dry-hanging method, this invention applies the principle of ratchet unidirectional movement positioning and reverse locking to provide a flexible dry-hanging structure for building exterior wall decorative panels that is simple in structure, has high positioning accuracy, does not damage the panels, has reliable connection, and high installation efficiency.
