Security Analysis of Rock Wool Board Exterior Wall Insulation System Under the Effect of Wind Load

In recent years, several accidents occurred about rock wool board thin plastering exterior insulation system is blown off by strong wind in our country, affecting the popularization and application of the system in the project. To study on rock wool board exterior wall insulation system security, this paper take a high-rise building in Jinan as the research object, and research results show that under the condition of meeting the existing rules technology, the theoretical calculation value of wind load bearing capacity is far greater than the wind load bearing capacity design value of rock wool board thin plastering system. The main technical parameters affecting the wind resistance of the system are tested in the field on this basis, test results show that test values of rock wool board and grassroots bonding area bonding strength is far less than the limit value, but the system also has a certain security reserve when compared with the design value of wind load .Finally, based on the comparative analysis of the theoretical and experimental results, we put forward the corresponding technical measures to improve the safety of the rock wool board thin plastering exterior insulation system undering the action of wind load.
