Equipment and method for detecting burst tendency of glass of curtain wall

Abstract

The invention discloses equipment and a method for detecting the burst tendency of glass of a curtain wall. A strain material is used for detecting the distortion degree of the glass, a strain gauge pressure sensor is closely contacted with the surface of the glass to be measured by a negative pressure absorption device, the deformation of a strain gauge is completely consistent with that of the glass in an ideal state, the deformation degree of the glass of the curtain wall can be determined by processing a deformation signal by using a measurement detection circuit, and the magnitude of stress inside the glass is indirectly obtained through calculation, so that the safety of the glass of the curtain wall can be conveniently and quickly detected in real time on the spot. The invention has the advantages that: 1, by the measurement method, the function of real-time, on-site, quantitative and quick measurement is realized, and the method is low in measurement cost and is safe, convenient, efficient and accurate; and 2, measured data can be accurately and timely sent into a computer, and an intact detection database is established so as to store the measured data, so that a good reference basis is provided for the regular measurement and evaluation in the future.

Description

technical field [0001] The invention relates to a detection device, in particular to a curtain wall glass bursting tendency detection device and a detection method; it belongs to the technical field of curtain wall glass bursting tendency and prevention detection in the building decoration industry. Background technique [0002] Glass curtain wall is a new type of contemporary wall. With the development of my country's economy, it has been widely used for one or two decades. Organically unified, however, this extensive use has also brought new safety hazards - the bursting of curtain wall glass! Its severity has endangered the safety of personal and property! In order to better prevent and discover such hidden dangers in a timely manner, it is particularly important to inspect the quality of curtain wall glass. Here is a simple analysis of the reasons for the bursting of curtain wall glass. [0003] At present, the structure of glass curtain wall is basically full glass cur...

[0005] 2. Curtain wall frame: After the curtain wall frame is installed, it must be adjusted and calibrated to ensure flatness. However, as time goes by, the building foundation will sink, the wall will tilt, etc., these changes will be transmitted to the aluminum alloy frame, and the glass After fixing, under the action of static load and dynamic load, the frame will also be deformed and the flatness will be changed.

[0008] 5. In addition, because the curtain wall glass is used outdoors, long-term wind blowing, sun exposure, rain forest, uneven temperature changes, etc. will aggravate the changes in the structure of the glass itself, making the glass more fragile, with a decrease in the deflection coefficient and resistance to deformation. weakened capacity

[0010] Due to the social hazards caused by the bursting of curtain wall glass, the state has also issued the "Standards for the Saf
