Description

Technical Field

[0001] The invention relates to an external thermal insulation connection system for an exterior wall of a metal decorative plate, belonging to the technical field of building thermal insulation systems. Background Art

[0002] The construction sector is a significant energy and resource consumer with significant environmental impact. Building energy conservation is a fundamental approach to alleviating energy shortages, improving living conditions, reducing environmental pollution, and promoting sustainable economic development. Building energy consumption in my country accounts for 46.7% of total societal energy consumption, with energy consumption during building operation alone accounting for 27.6%. This proportion is expected to continue to increase as urbanization accelerates. Developing energy-efficient and green buildings has become a crucial component of national energy conservation and emission reduction efforts. Implementing energy conservation measures for building envelopes is an effective and important approach to achieving energy conservation goals. Currently, almost all wall insulation in my country utilizes external insulation technology, accounting for over 95% of engineering applications.

[0003] External wall insulation is an insulation method that places an insulation layer outside the main wall material. It is currently the most widely used insulation method. Although external wall insulation technology has developed rapidly in my country, traditional external wall insulation systems represented by pasted insulation board thin plastering, insulation slurry composite insulation board, and sprayed rigid polyurethane foam have many problems in their promotion and application and engineering practice over the years. For example, external wall insulation projects often suffer from quality and safety issues such as hollowing, cracking, shedding, and fire, which pose a great quality and safety hazard to the project. The new external wall insulation technology represented by the metal-faced decorative panel external wall insulation system can integrate the insulation material with the wall structure, eliminating the need for other insulation treatments. It has the characteristics of good insulation and fire resistance, reliable quality and safety, and integrated insulation and fire protection decoration. The metal-faced decorative panel external wall insulation system is gaining more and more attention.

[0004] The metal decorative panel exterior wall insulation system still has the following deficiencies in its specific application:

[0005] 1. The connection between the decorative panels is prone to being loose, and the connection between the base wall and the external rock wool board is prone to being loose, resulting in low wind load resistance of the decorative panels and the risk of falling off.

[0006] 2. The joints between decorative panels are generally filled with sealant to ensure a tight joint. The sealant application process is relatively complicated, and as the sealant ages, the strips will fall off and age, and the sealant will peel off from the panel, resulting in sealing failure.

[0007] 3. Both ends of the decorative panels are generally designed as male-female plug-in structures. This not only makes the installation process of the decorative panels cumbersome, but also increases the difficulty of production and increases the production cost of the decorative panels.

[0008] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0009] In response to the deficiencies in the background technology, the present invention provides a metal-faced decorative panel exterior wall insulation connection system, which can firmly connect the metal-faced decorative panels, firmly connect the base wall and the external rock wool board, and well seal the joints between the decorative panels, making the decorative panel structure simple and reasonable, and reducing the difficulty and production cost of the decorative panel production.

[0010] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0011] A metal-faced decorative panel exterior wall external insulation connection system includes a base wall, and a rock wool board and a decorative panel are installed in sequence on the outer surface of the base wall; the decorative panel is fixed by a fixed pressure combination connector; the fixed pressure combination connector includes a fixed pressure seat, a fixed pressure strip and a self-locking buckle line, the fixed pressure strip presses the bent portion of the decorative panel into the U-shaped cavity of the fixed pressure seat, and the U-shaped opening of the fixed pressure strip is buckled with a self-locking buckle line; the self-locking buckle line includes a first self-locking buckle line and a second self-locking buckle line.

[0012] An optimized solution is that the fixed pressure seat is installed in the gap between adjacent rock wool boards, and an expansion anchor bolt is installed at the bottom of the fixed pressure seat, and the expansion anchor bolt is anchored in the base wall.

[0015] Furthermore, the fixing strip is fixed to the bottom of the fixing seat by self-tapping screws, and the fixing strip fixes the bent portion of the decorative plate on the limiting convex strip in the fixing seat.

[0016] Furthermore, the decorative panel includes a first decorative panel and a second decorative panel; both ends of the first decorative panel are respectively provided with bending portions; one end of the second decorative panel is provided with a bending portion, and the other end is provided with a gusset portion.

[0019] Furthermore, the pressure fixing seat is fixed by a plurality of expansion anchor bolts; the pressure fixing strip is fixed by a plurality of self-tapping screws; and the center lines of the expansion anchor bolts and the self-tapping screws are not in a straight line.

[0020] After adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0021] The fixed pressure seat in the fixed pressure combined connector is installed in the gap between adjacent rock wool boards. The fixed pressure seat is anchored in the base wall, which can improve the bonding force between the rock wool board and the base wall, making the two firmly connected. The fixed pressure seat plays a good supporting and fixing role for the rock wool board;

[0022] The fixed pressure strip in the fixed pressure combined connector fixes the bent portion of the decorative panel in the fixed pressure seat and is fixed by self-tapping screws.
