In addition to the quality of raw materials, the safety and weather resistance of exterior wall decoration thermal insulation integrated panels also partly depend on the construction technology and methods. At present, the construction methods of integrated board are mainly divided into three types, namely adhesive and anchor bonding, dry hanging and pasting. Let’s start with a commonly used method - bonded anchoring, which is also a safer installation method than the other two methods. First, cut the thermal insulation and decorative integrated board to the specified size according to the layout diagram, and open a groove 5 mm wide and 3 mm deep around the board. Apply a layer of bonding mortar behind the integrated board, which can be fixed to the bottom of the wall through point-frame bonding. At the same time, special anchors are embedded at the joints of the overall panels. The anchors penetrate the wall through insulation expansion bolts and then scrape the grooves.
The second is the dry hanging type, which is somewhat similar to the way of dry hanging stone. Steel joists need to be pre-installed on the wall base. The integrated board of the exterior wall is connected to the keel through special anchors, and the integrated board and the wall base are filled with foam polyurethane or other materials. There is also a bonding installation method, that is, the exterior wall decorative insulation integrated board and the wall only need to be bonded with a special high-strength bonding mortar. The bonding area needs to reach more than 80%, and the joints of the boards are bonded with Sealing with mortar or polyurethane etc.
The above is an introduction to several construction methods of integrated panels. After several years of development and improvement, the integrated panels for exterior wall decoration and insulation have been subject to news that the insulation layer of exterior walls has fallen off from time to time. Now the integrated panels are installed using bonding and anchoring. The hidden dangers are eliminated at the root, making it safer.
