A curtain wall air tightness detection device and detection method thereof

Abstract

The invention relates to a curtain wall air tightness detection device, which includes a pressure box, a pressure supply component and a measurement component; the pressure box includes an outer box that fits on the surface of the curtain wall and an inner box that is arranged in the outer box and fits on the surface of the curtain wall body, the outer wall of the inner box perpendicular to the surface of the curtain wall and the inner wall of the outer box perpendicular to the surface of the curtain wall are slidingly matched and sealed; the surface of the inner box and the curtain wall is fixed with a first sealing ring around the opening of the inner box , the surface of the outer box and the curtain wall is fixed with a second sealing ring around the opening of the outer box; the outer box is provided with a mounting piece fixed to the beam; the pressure supply component includes an air pump and an air pipe, and the outer box is parallel Between the inner side wall of the curtain wall and the outer side wall of the inner box body parallel to the curtain wall, there are control valves communicating with the outer box body and the inner box body respectively, and the gas pump communicates with the control valve. The invention has the effect of good airtightness, and improves the detection accuracy of the airtightness of the curtain wall.

Description

technical field [0001] The invention relates to the technical field of building detection, in particular to a curtain wall air tightness detection device and a detection method thereof. Background technique [0002] Curtain wall refers to the non-load-bearing outer wall enclosure of a building, usually composed of panels (glass, metal plate, stone slab, ceramic plate, etc.) Composed of panels (glass, metal panels, stone panels, ceramic panels, etc.) and supporting structures behind (aluminum beams and columns, steel structures, glass ribs, etc.). The building curtain wall needs to be tested for building physical performance (wind pressure resistance performance, air permeability performance, rainwater leakage performance, plane deformation performance test report), which is generally called the four-characteristic test of the curtain wall. Among them, the air tightness test method of the curtain wall is the existing national standard test method (GB / 15227-2007). The detect...

Problems solved by technology

Therefore, the sealed connection between the pressure box and the curtain wall is the key to the detection accuracy. The existing detection devices still sometimes have poor sealing between the pressure box and the curtain wall surface, resulting in inaccurate detection data.
