Problems solved by technology

However, this manual detection method has the following deficiencies: 1. This manual detection method of installing acceleration sensors and data acquisition devices on site to collect acceleration data, disassembling them and bringing them back to the testing center for analysis has the problem of high efficiency and low cost.
2. Each inspection needs to be installed and disassembled. In addition to low efficiency, for some places, each inspection requires high-altitude operations, which is highly dangerous
3. The method of regular inspection has a long time span (such as one month, half a year or even one year, etc.), and the structural damage of the adhesive may have intensified beyond the safe range before the next inspection, and the glass plate may fall. , there is still the possibility of serious threats to public life and property safety
[0008] However, it does not consider the influence of one or more of the simultaneous effects of different partitions of the building, internal and external temperature differences, glass bearing capacity, steel stress, and relative deformation of the glass curtain wall on the structure.

Embodiment 1

[0037] A method for monitoring the safety of a glass curtain wall structure, comprising the following steps:

[0038] Step 1: Sensor Setup

[0039] Such as figure 1As shown, a temperature sensor 1, a pressure sensor 2, a stress sensor 3, and a displacement sensor 4 are arranged on the glass curtain wall structure. The temperature sensor 1 includes an outdoor temperature sensor 11 and an indoor temperature sensor 12, and the outdoor temperature sensor 11 and the indoor temperature sensor 12 are respectively arranged on the outside and inside of the glass curtain wall. A pressure sensor 2 is pasted on the outer surface of the glass 5 . A stress sensor 3 and a displacement sensor 4 for measuring relative deformation are pasted on the keel 6 of the glass curtain wall structure.

[0040] Step 2: Parameter Measurement

[0041] The outdoor temperature sensor 11 measures the outdoor temperature W 外 , the indoor temperature sensor 12 measures the indoor temperature W 内 , W 内 -W ...

Embodiment 2

[0056] In this example, if figure 1 , 3 , 4, according to the structural function, the structural plane is divided into four partitions, the office area is the first partition, the rest area is the second partition, the entertainment area is the third partition, and the reception area is the fourth partition. The early warning coefficient values ​​A, B, C, D of the first partition are 40%, 70%, 100% and 120% respectively, and the early warning coefficient values ​​A, B, C, D of the second partition are 50%, 80%, 80%, respectively. 105% and 125%, the warning coefficient values ​​A, B, C and D of the third division are 55%, 85%, 110% and 130% respectively, and the warning coefficient values ​​A, B, C and D of the fourth division are respectively 60%, 90%, 110%, and 130%. Other structures and sensor settings and monitoring steps are the same as in Embodiment 1, and will not be described in detail here.

Abstract

The invention relates to a method for monitoring safety of a glass curtain wall structure. The method comprises the following steps: sensors are arranged, specifically, the temperature sensor, the pressure sensor, the stress sensor and the displacement sensor are arranged on the glass curtain wall structure; parameters are measured, specifically, the indoor and outdoor temperature difference deltaW is measured, the glass surface pressure P is measured to obtain glass bearing force P<bearing>, and a keel stress value rho and a relative deformation value D<X> are measured; the glass curtain wall structure is partitioned; early warning values are set, specifically, the early warning factor values are set as A, B, C and D; and graded and partitioned early warning is conducted, specifically, the same or different early warning factor values are set for different partitions, and early warning colors of the partitions are displayed on a monitor. Monitoring data are more objective and more comprehensive, the safety of the glass curtain wall structure is guaranteed better, monitoring and early warning can be conducted in real time, and the automation degree is high.

Description

technical field [0001] The invention relates to a monitoring method, in particular to a glass curtain wall structure safety monitoring method, and belongs to the technical field of civil engineering structure monitoring. Background technique [0002] In modern buildings, glass curtain walls are widely used because of their relatively light materials, simple construction techniques, and the ability to easily build various and elegant high-rise buildings. [0003] The glass plates of existing glass curtain walls (especially hidden frame glass curtain walls and full glass curtain walls) are mainly bonded and fixed by viscose (or structural glue). However, after the glass curtain wall has been in service for a long time, its viscose will suffer structural damage caused by factors such as aging and local shedding, and as the degree of structural damage increases, the adhesive force of the viscose to the glass plate will continue to decline, and at the same time , the rate of cha...
