Background
The thin-plastered structure always occupies the market leading position due to the heat insulation structure with the best cost performance, but in recent years, great loss is caused to people's life and property due to the falling accidents of the thin-plastered external wall heat insulation system. At present, a plurality of banning policies aiming at the application of the external wall thin plastering heat preservation system are provided.
The inorganic light aggregate insulation board external wall insulation system is applied to summer hot and winter cold areas for many years in a large scale, and has a good effect. In recent years, the design standard of building energy conservation is improved in various places, the use thickness of the heat insulation material is correspondingly increased, the self weight of a heat insulation system is increased, people naturally worry about the safety performance of the heat insulation system, and the heat insulation system cannot be accepted only by the simple external heat insulation of the external wall or the internal heat insulation of the external wall. Therefore, the external and internal combined heat insulation structure of the external wall becomes the only choice, which causes the manufacturing cost to rise greatly.
At present, two common external heat preservation methods are available, namely thin plastering and heat preservation decoration integration. The former is a combination of a binder, an inorganic light aggregate insulation board, an alkali-resistant mesh, an anchor bolt and rendering adhesive cement, needs multiple constructions, and has large self weight of the inorganic light aggregate insulation board with large thickness. The latter is a combination of adhesive, heat-insulating decorative plate and anchoring component, and is required to be typeset in advance.
The key disadvantages of the external wall plastering system are 2: first, security is not sufficient. When the inorganic light aggregate insulation board is large in thickness, the self weight is large, and the inorganic light aggregate insulation board has the risk of falling under various actions of the external environment by virtue of the binder. The length of the adopted anchor bolt is limited, and when the thickness of the inorganic lightweight aggregate insulation board is larger, the anchoring depth is insufficient, so that the inorganic insulation board is not fixed. In addition, due to the uncertainty of field construction and the adoption of a thin plastering technology, the risk of falling of the external wall heat insulation material is high and the external wall heat insulation material is not safe enough. Second, the quality of the finish layer is prone to problems. The plastering mortar is constructed on site, has large quality fluctuation, is easy to have the problems of insufficient plastering thickness, cracking, dry adhesion of screen cloth and the like, causes water seepage, stripping and damage of the heat-insulating layer, finally leads to the falling of the heat-insulating layer and causes safety accidents.
At present, two common external heat preservation methods are available, namely thin plastering and heat preservation decoration integration. The former is a combination of a binder, an inorganic light aggregate insulation board, an alkali-resistant mesh, an anchor bolt and rendering coat mortar, multiple construction is needed, and the inorganic light aggregate insulation board with large thickness has large dead weight. The latter is a combination of adhesive, heat-insulating decorative plate and anchoring component, and is required to be typeset in advance.
