Background
In the current building construction industry, the problem that the external wall insulation board falls off becomes a serious potential safety hazard, and great threat is caused to personal and property safety of owners. The severity of this problem is mainly due to the following aspects.
First, the existing adhesives have disadvantages in terms of compatibility and adhesion. The external wall heat insulation board is influenced by external environment for a long time, such as erosion of rainwater and the effect of wind, and the adhesive is easy to age and deteriorate, so that the adhesive force is reduced. This weakens the bond between the insulation board and the wall, increasing the risk of falling out.
Secondly, the anchoring form between part of the external wall insulation boards and the wall surface has defects. The current common hollow rivet anchoring mode has some problems in the construction process. The anchoring force is limited by the hollow rivet, and the requirement of long-term stable tensile property cannot be met. These problems make the exterior wall insulation board easily displace and separate from the wall under the action of external load.
Therefore, there is an urgent need to design a new anti-falling reinforcing structure for external wall insulation boards to solve these problems. This kind of structure needs to increase extra constraint power between heated board and wall body to ensure that the heated board can firmly be fixed on the wall body, improve holistic anti-wind pressure and shock resistance, thereby effectively prevent the drop phenomenon of heated board. By introducing new reinforcing measures, the bonding strength and stability between the external wall insulation board and the wall body can be improved, the falling risk is reduced, and a safer and more reliable environment is provided for users of the building.
