Description
Technical Field
The utility model relates to an kind of building exterior window gas tightness sealing device for witnessed inspections belongs to exterior window leakproofness witnessed inspections technical field.
Background
The building external window is an important component of a building enclosure structure, plays roles of lighting, sun-screening, sun-shading, ventilation, water resistance, sound insulation and the like, and has data to prove that the energy consumption of the window loss through accounts for 45-50% of the energy consumption of the building, the external window becomes a weak link in building energy conservation in China.
In order to fully achieve the building energy-saving standard of not less than 65% of the execution of newly built buildings in cities and towns, 3.3.5 in the public building energy-saving design Standard GB50189-2015 of the existing building design standard definitely stipulates that the air tightness of the building external window is required to meet the requirement that (1) the air tightness of the building external window with more than 10 floors is not less than 7 grade, namely the unit seam length is 1.0 to q, namely the unit seam length is more than or equal to 1.01[m3/(m·h)]Greater than 0.5, and unit area of 3.0 ≥ q2[m3/(m2·h)]Is more than 1.5; (2) the air tightness of the building external window below 10 floors should not be lower than 6 grades, i.e. the unit seam length is 1.5 ≥ q1[m3/(m·h)]Greater than 1.0, unit area 4.5 ≥ q2[m3/(m2·h)]Is more than 3.0; furthermore, 5.1.3 in "acceptance Specification for construction quality of architectural decoration and finishing works" GB50210-2001 and 6.2.2 in "acceptance Specification for construction quality of architectural energy saving works" GB50411-2007 explicitly stipulate completionBefore acceptance, the air tightness of the building external window needs to be subjected to entrance recheck or on-site entity inspection, so that the air tightness of the building external window is ensured to meet the related energy-saving design requirements.
At present, the air tightness of the building external window is more and more emphasized, the field detection work is increased year by year, the requirement is also more strict, a transparent plastic film (the thickness is more than or equal to 0.2mm) is required to be used for sealing in the detection process which is clearly specified in the existing ' field detection of the building external window ' JG/T211-2007 ' in China, and in the field air tightness detection process, a plurality of sand-lime wall surfaces exist, and the sealing degree is difficult to ensure only by the plastic film; the surface of the outer window of a part of buildings is provided with a waterproof film, so that the sealing difficulty is increased, and the additional permeation quantity and the accuracy of a measuring result are seriously influenced. And the sealing plate is often smaller in size in the actual air tightness detection process, so that the field detection requirement is difficult. The sealing plate is difficult to disassemble after detection is finished, time and labor are consumed, and the air tightness detection efficiency of the building outer window is seriously influenced.
