Curtain wall air tightness detection device and detection method thereof

Abstract

The invention relates to a curtain wall air tightness detection, device which comprises a pressure box, a pressure supply assembly and a measurement assembly. The pressure box comprises an outer box body attached to the surface of the curtain wall and an inner box body arranged in the outer box body and attached to the surface of the curtain wall. The outer wall, perpendicular to the surface of the curtain wall, of the inner box body and the inner wall, perpendicular to the surface of the curtain wall, of the outer box body are in sliding fit and are movably sealed. A first sealing ring surrounding an opening of the inner box body is fixed to the surface, attached to the curtain wall, of the inner box body, and a second sealing ring surrounding an opening of the outer box body is fixed tothe surface, attached to the curtain wall, of the outer box body. The outer box body is provided with a mounting piece fixed with the cross beam; the pressure supply assembly comprises an air pump andan inflating pipe, control valves communicated with the interior of the outer box body and the interior of the inner box body respectively are arranged between the inner side wall, parallel to the curtain wall, of the outer box body and the outer side wall, parallel to the curtain wall, of the inner box body, and the inflating pipe is communicated with the control valves. The curtain wall air tightness detection device has the effect of good sealing performance, and the curtain wall air tightness detection precision is improved.

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.
