[0002] With the increasing requirements for aesthetics and building energy conservation, the exterior wall sandwich insulation decorative integrated board has emerged as a new type of building material with both decorative and thermal insulation functions. At the same time, to ensure the reliability of actual application in construction projects, a special test analysis system is needed for accurate evaluation.

[0003] During the operation of the traditional test and analysis system for exterior wall sandwich insulation decorative integrated panels, it is impossible to accurately analyze and determine the performance of the integrated panels, nor is it possible to accurately determine the safety status of the integrated panels and integrated panel connectors of the building. As a result, maintenance personnel cannot be notified in time to reinforce and process the integrated panels of the building, resulting in frequent safety accidents and greatly reducing residents' satisfaction and comfort with their living spaces.

[0004] In order to solve the above defects, a technical solution is now provided. Summary of the invention

[0005] In order to solve the technical problems raised by the above background technology, the present invention is proposed. An embodiment of the present invention provides a test and analysis system for an integrated sandwich thermal insulation and decorative panel for an exterior wall.

[0006] The purpose of the present invention can be achieved through the following technical solutions: a test analysis system for exterior wall sandwich insulation decoration integrated panels, including a data acquisition module, a performance detection module, a panel installation analysis module, a connection analysis module and an early warning management module.

[0007] The data acquisition module is used to collect test information, region information, floor information, integrated panel information, and connector information, and send them to the performance detection module, the panel installation analysis module, and the connector analysis module;

[0008] The performance detection module is used to analyze the freeze-thaw resistance, weather resistance and building shape coefficient of the integrated panel to obtain a performance thickness determination signal;

[0009] The board safety analysis module is used to analyze the deflection and stress of the integrated board to obtain a safety determination signal of the integrated board;

[0010] The connection analysis module is used to analyze the stress of the connection, the stress of the bolt, the shear force of the bolt and the pull-out bearing capacity of the anchor bolt to obtain a safety determination signal of the connection;

[0011] The early warning management module is used to receive the performance thickness determination signal, the integrated panel safety determination signal and the connector safety determination signal, make determination and analysis on the comprehensive status of the integrated panel, and make corresponding early warning management measures.

[0012] Furthermore, the performance thickness determination signal analysis steps are as follows:

[0013] Substitute the freeze-thaw resistance value Nd of the integrated board, the thermal conductivity dr of the integrated board, the climatic conductivity value Ph of the integrated board and the building shape coefficient tx into the set formula Ysh=ζ×dr×tx×Ph / Nd to obtain the required thickness value Ysh of the insulation layer, where ζ is the set correction factor coefficient, obtain the thickness value of the integrated board of the building, and subtract the required thickness value of the insulation layer to obtain the excess thickness value of the integrated board;

[0014] When the value of the integrated plate thickness exceeding the standard is greater than or equal to zero, a corresponding normal performance thickness signal is issued. When the value of the integrated plate thickness exceeding the standard is less than zero, a corresponding abnormal performance thickness signal is issued.

[0015] Furthermore, the steps for analyzing the climatic derivative value and building shape coefficient value of the integrated panel are as follows:

[0018] Furthermore, the crack expansion stress value, hole value, material interaction value and thermal conductivity of the integrated plate are analyzed as follows:

[0019] The exterior wall sandwich insulation and decorative integrated panels in the building are subjected to weathering tests to obtain the crack expansion rate, crack branching density, and crack tip stress intensity factor, and the crack expansion stress value is obtained by summing them up to obtain the fringe order and multiplying it by the correction factor coefficient.

The bonding interface area of ​​the integrated panels was analyzed by energy spectrum analysis to obtain the element types and relative contents of each point. When the element content exceeds the set threshold, The corresponding point is attributed to the element aggregation area, and the ratio of the area of ​​the element aggregation area to the area of ​​the entire bonding interface is calculated, which is marked as the aggregation value of the integrated board. The glass fiber surface coating before and after freezing and thawing is analyzed by Fourier transform infrared spectroscopy to obtain the change rate of the glass fiber absorption peak intensity. The element distribution on the coating surface is detected by energy spectrum analysis to obtain the area of ​​element missing and new element areas. The sum and division by the total area give the glass fiber element change rate. The microscopic morphology crack value of the integrated board, the aggregation value of the integrated board, the change rate of the glass fiber absorption peak intensity and the glass fiber element change rate are calculated to obtain the freeze-thaw resistance value Nd of the integrated board.
