Bondability detection device for exterior wall face of building

Abstract

The invention discloses a bondability detection device for an exterior wall face of a building. The device comprises a power supply and a computer. The device is characterized by also comprising an ultrasonic emitting device which is electrically connected to the power supply for injecting heat to an exterior wall of the building by emitting ultrasonic waves and an infrared thermal imager device for infrared nondestructive testing for the exterior wall of the building with the heat injected, separately, wherein the infrared thermal imager device is provided with a signal output interface in signal connection to the computer. Based on the ultrasonic probe technology, non-contact, long-distance, real-time and fast infrared thermal imaging detection can be performed on the exterior wall of the building can be performed by taking the infrared thermal image detection technology as a detection main body, so that the device has the advantage of quickly and accurately detecting defects such as hollowness in the exterior wall and etc.

Description

technical field [0001] The invention relates to a building detection device, in particular to a building exterior wall decoration fixing force detection device. Background technique [0002] With the development of the times, the building decoration tool of exterior wall tiles has been popularized, but due to various external factors, the phenomenon of its falling off occurs from time to time, which poses a serious threat to human safety. Under the premise of considering intrinsic safety, it has become a trend to study how to predict and discover potential dangers in advance. [0003] The gradual deepening of urbanization has led to urbanization factors such as urban unnatural winds posing serious challenges to the strength of the outer walls of high-rise buildings. Casualties caused by the peeling off of exterior wall finishes of high-rise buildings frequently occur. Considering the goal of building a harmonious city and putting people first, more and more attention has be...

AI Technical Summary

Problems solved by technology

[0006] (2) If a rigid pointing agent is used, it cannot effectively absorb the deformation of the tiles, and the temperature deformation of the tiles without expansion joints cannot release the huge internal compressive stress, and finally the tiles fall off due to arching in the middle of the stress.

[0007] (3) As the climate changes, the physical and chemical properties of the adhesive itself lead to a weakening of the bonding ability

At present, cement is mostly used as raw material for building exterior wall adhesives. If the thermal expansion coefficients of tiles and cement are different, there will be temperature difference stress after the tiles are laid, and seasonal temperature fluctuations will cause the bonding strength to decrease.

[0008] (4) Between the tiles, especially the large-size tiles, the joints are too small, and the tiles will expand and contract with each other and squeeze each other, causing warping and cracking

[0009] Many of the above unfavorable conditions eventually lead to the shedding of exterior wall facing bricks, resulting in unacceptable losses
