Field detection method and device for glass temperature stress of glass curtain wall

Abstract

The invention discloses a field detection device for glass temperature stress of a glass curtain wall. The field detection device comprises an electrical heating box, a temperature sensor, a temperature acquisition instrument, a power source, a strain foil, a strain gauge, a supporting rod, a wireless data transmitter and a wireless data receiver, wherein one face of the electrical heating box isfixed to the wall body through the supporting rod, and the other face is closely attached to test glass; the temperature sensor is arranged on the test glass; the temperature acquisition instrument is provided with the wireless data receiver; the electrical heating box and the temperature sensor are in wireless data connection with the temperature acquisition instrument; and the strain foil is arranged on the test glass and is connected with the strain gauge through a wire. The invention also discloses a field detection method for the glass temperature stress of the glass curtain wall. The field detection device and the field detection method can be used for identifying the safety of the structure of the glass curtain wall and can also be used for checking the construction quality of a glass curtain wall in construction.

Description

technical field [0001] The invention relates to on-site detection of glass temperature stress, in particular to a method and device for on-site detection of glass temperature stress in a glass curtain wall. Background technique [0002] With the increasing development of my country's economic construction and urbanization, high-rise and super high-rise buildings in cities are springing up like mushrooms after rain. Since the 1980s, the emerging glass curtain wall enclosure structure with many advantages such as modern aesthetics, short construction period and light weight has been widely used in high-rise and super high-rise buildings in cities. With the use of glass curtain walls in engineering construction, my country's engineering circles have insufficient knowledge reserves for glass curtain wall design, construction, inspection and management. In some areas, casualties, safety and quality accidents have occurred due to improper glass curtain wall design, construction or...

AI Technical Summary

Problems solved by technology

[0003] Before the construction and installation of glass curtain wall glass, only laboratory tests are done, and the glass temperature stress related to the quality of on-site glass curtain wall glass construction and installation cannot be detected at present, and there is no on-site temperature stress detection device for glass curtain wall glass

Therefore, under the influence of the temperature difference between the inside and outside of the glass curtain wall that is under construction or has been used for more than ten years, the glass with frame constraints will cause deformation, cracking and falling.
