The invention discloses a sealing device for on-site testing of the airtightness of building exterior windows and a method of use, comprising a first corner plate, a second corner plate and a support frame, both ends of the first corner plate and the second corner plate are A chute is provided, an extension board is placed in the chute, a sliding mechanism connected with the extension board is provided on the inner top of the chute, a butt joint is fixed at the end of the extension board, and the two corner boards of the second corner The side walls of the butt joints on the ends are fixed with plugs, and the plugs are provided with locking mechanisms, and the side walls of the butt joints at both ends of the first corner plate are provided with slots corresponding to the plugs. Both the upper ends of the first corner plate and the second corner plate are fixed with a backing plate, the upper end of the backing plate is provided with a groove, and an insertion mechanism is arranged in the groove. The invention has reasonable structure, can adapt to the sealing of different outer window sizes, has good sealing effect, and can detect the specific position where gas escapes.
Description
technical field [0001] The invention relates to the technical field of airtightness detection of building exterior windows, in particular to a sealing device and a use method for on-site detection of airtightness of building exterior windows. Background technique [0002] Building exterior windows are an important part of the building envelope, which play the role of lighting, sun protection, ventilation, waterproof and sound insulation, etc. It is proved by data that energy consumption lost through doors and windows accounts for 45% to 50% of building energy consumption. %, external windows have become a weak link in my country's building energy conservation. With the application of new technologies and new materials, higher requirements are put forward for the performance of external windows in civil buildings. Air tightness is an important index in the performance of external windows of buildings. direct impact. [0003] The existing sealing plate is generally used to se...
