Problems solved by technology

However, in addition to the installation of the airtight metal roof, the patent does not disclose the installation method of the airtight edge of the cornice and the gable wall, and the airtight construction of the roof must not only ensure the airtight requirements of the metal roof system, but also ensure the airtight roof The airtightness of the edges of the eaves and gables, otherwise the airtightness and cleanliness requirements of the clean room cannot be guaranteed
[0004] Therefore there are above-mentioned inconveniences and problems in the known airtight heat-insulating metal roof and construction method thereof

Abstract

An airtight metal roof cornice and gable airtight edge installation method, characterized in that it comprises the following steps: a. airtight metal roof cornice airtight edge installation and b. airtight metal roof gable airtight side installation. The airtight metal roof cornice and gable airtight edge installation method of the present invention has the advantages of reasonable design of airtight edge manufacturing steps, simple operation, reliable airtight edge engineering quality, and excellent airtight performance.

Description

technical field [0001] The invention relates to a method for installing metal roofs, in particular to a method for installing airtight edges of cornices and gables of airtight metal roofs. Background technique [0002] The area of ​​the process production floor in the main workshop of the electronic industry such as electronic chips and liquid crystal displays usually reaches 40,000-100,000m 2 , The production process determines that the main workshop must have the requirements of large space, high cleanliness and airtightness. The airtightness of the roof of the clean factory requires that under a positive pressure of 10Pa, the air leakage rate of the roof system is less than 0.03m 3 / h.m, where h stands for hour, m stands for meter, and meter refers to the length of the gap, that is, the length of all doors and windows and other joints; under the positive pressure of 120Pa, the air leakage rate of the roof system is less than 0.09m 3 / h.m; the highest cleanliness level r...
