[0002] Glass curtain wall refers to the building's external protective structure or decorative structure that has a certain displacement capacity relative to the main structure and does not share the effects on the main structure. Glass curtain wall is a beautiful and novel method of building wall decoration, and is a prominent feature of the modernist high-rise building era. With the rapid development of the modern construction industry, the application of glass curtain walls in buildings has become more and more extensive. In order to ensure the safety and stability of glass curtain walls during use, the quality of glass curtain walls is usually tested before they are installed and used.

[0055] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0056] Embodiment 1

[0057] A quality inspection system for building glass curtain walls, such as Figure 1 As shown, several glass curtain wall samples to be tested in the same batch are prepared for standby, and then the test temperature is adjusted to the required state (such as low temperature -30℃-10℃, normal temperature 15℃-25℃, high temperature 30℃-50℃) through the temperature control unit. At the adjusted test temperature, the pressure-bearing test module in the quality inspection unit and the bending test module are used to apply pressure on several glass curtain wall samples to be tested, until the glass curtain wall samples to be tested are broken, so that several groups of pressure-bearing data and several groups of bending angle data can be obtained. At the same time, several glass curtain wall samples to be tested are placed in different ambient temperatures (such as 35℃, 40℃, 45℃, 50℃, ...) through the temperature resistance test module for temperature resistance testing until the glass breaks, so that several groups of temperature resistance data can be obtained.

[0058] Then, the above data is collected by the data collection unit and handed over to the data preprocessing unit for preprocessing. The data is first classified by the data classification module. For example, all the data obtained from the pressure test are classified into the pressure test; then the data selection module is used to select the representative data in each category. When selecting the pressure and bending resistance data, if:

[0059]

[0060] If the data Da is not equal to 1, the data Da will be discarded, otherwise, the data Da will be retained; i Da is the result data of each pressure or bending test at different temperatures T. max 、Da min is the maximum and minimum test result data of several pressure or bending tests at different temperatures T, and Z1 is the total number of pressure or bending tests at different temperatures T;

[0061] When selecting temperature resistance data, if:

[0062]

[0063] If the data Da is not equal to 1, the data Da will be discarded, otherwise, the data Da will be retained; i is the result of each temperature resistance test, Tp max , Tp min Tp is the maximum and minimum test result data in several temperature resistance tests. a is the ambient temperature, and Z2 is the total number of temperature resistance tests.

[0064] After completing the selection of each type of data, each type of data selected will be forwarded to the core processing unit through the data forwarding module. The data receiving module in the core processing unit will receive the data and hand over the received data to the data analysis module for analysis and processing. When analyzing the pressure and bending test data, if:

[0065]

[0066] If the pressure-bearing or bending-resistance performance of the tested glass curtain wall is not up to standard, otherwise, the pressure-bearing or bending-resistance performance of the tested glass curtain wall is up to standard; where d j is each pressure or bending test data at different temperatures T, S1 is the total number of pressure or bending test data at different temperatures T, γ T The pressure bearing or bending resistance threshold parameters are preset at different temperatures T;

[0067] When analyzing the temperature resistance test data, if:

[0068]

[0069] If the temperature resistance of the glass curtain wall under test is not up to standard, otherwise, the temperature resistance of the glass curtain wall under test is up to standard; where f j For each temperature resistance detection data, S2 is the total number of temperature resistance detection data, and δ is a preset temperature resistance threshold parameter.

[0070] The results of the analysis and judgment are then fed back to the real-time data display unit through the result feedback unit for the inspection personnel to view.

[0071] Embodiment 2

[0072] Based on the first embodiment, Figure 1 As shown, a quality inspection system for building glass curtain walls, during the quality inspection of the glass curtain walls, determines whether the glass curtain walls are about to reach the limit state through the judgment module in the safety protection unit. During the pressure and bending inspection of the glass curtain walls, if:

[0073]

[0074] At this time, it is determined that the pressure bearing limit of the tested glass is about to be reached during the pressure bearing and bending resistance testing; wherein P is the pressure applied to the tested glass curtain wall, m is the elastic modulus of the tested glass curtain wall, and B is the Poisson's ratio constant of the tested glass curtain wall;

[0075] During the glass curtain wall temperature resistance test, if:

[0076]

[0077] At this time, it is determined that the temperature resistance limit of the glass being tested is about to be reached during the temperature resistance test; ch is the length change of the glass curtain wall being tested, α is the expansion coefficient of the glass curtain wall being tested, T o , T n are the preset temperature and the current temperature, L s is the initial length of the glass curtain wall being tested, and T is the temperature acting on the glass curtain wall being tested.

[0078] Then the personnel detection module detects whether there are personnel near the detection position (10-15m) of the inspected glass curtain wall. If there are personnel, the control instruction issuing module will issue a control instruction to the quality inspection unit to stop the quality inspection of the inspected glass, and perform sound and light alarm operation through the alarm module. Otherwise, the pressure, bending and temperature resistance tests of the inspected glass curtain wall will continue. This can greatly avoid the situation in which the glass curtain wall bursts after exceeding the limit state during the quality inspection process, and the splashing fragments quickly hit the personnel, causing injuries.

[0079] The electrical components that appear in this article are all electrical components that exist in reality.

[0080] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
