The super large multifunctional curtain wall testing equipment is independently developed by our institute,

The size of the equipment is (18 + 8) m wide and 22 m high, which can be used both inside and outside;
Multiple test pieces can be installed at the same time for independent detection
It can carry out the national standard / external standard performance test of plane / special-shaped super large curtain wall.

The test chamber can provide a maximum of ± 20000 PA (± 20KN / M) two )The pressure difference of;
The center wind speed of dynamic wind load can reach 50M / s;
The test piece can be evenly drenched, and the water amount can be calibrated as 4L / min / m according to the national standard and the United States two 、.4L/min/m two And 2L / min / m two At the same time, the stable or fluctuating wind pressure can be applied to the specimen;
Automatic test: air permeability of specimen under different pressure difference Deformation of each position and component  
Inter story displacement in three dimensional and six directions

It can undertake structural safety, normal usability appraisal, special inspection, calculation review and technical consultation of existing curtain wall; Roof and daylighting roof detection and identification; Inspection and identification of building doors and windows; Glass box, glass canopy, glass floor, outdoor billboard testing and identification and other technical services.
