Description

Structure bonding steel reinforcing quality detection equipment based on infrared thermal imaging Technical Field The invention belongs to the technical field of structural adhesive steel quality detection equipment, and relates to structural adhesive steel reinforcement quality detection equipment based on infrared thermal imaging. Background The method for reinforcing the bonded steel of the building structure has been widely applied to reinforcing and reinforcing various reinforced concrete structures such as bridges, high-rise buildings, industrial plants and the like due to the advantages of high strength, convenient construction, small influence on the original structure and the like. The technology is characterized in that a steel plate is adhered to the surface of a concrete member through a high-performance structural adhesive to jointly work, so that the aim of improving the bearing capacity and rigidity of the member is fulfilled. However, the reinforcing effect is highly dependent on the quality of the construction of the adhesive layer between the steel plate and the concrete substrate. The defects of hollowing, debonding and the like can seriously affect stress transmission, so that the steel plate cannot fully play a role, and even suddenly peels off under load to cause disastrous results. Therefore, the comprehensive quality detection and evaluation of the bonding steel reinforcement engineering is an important link for guaranteeing the structural safety. The traditional method for detecting the strengthening quality of the bonded steel mainly comprises a hammering method (knocking method) and a drawing method. The hammering method relies on experience of a detector, and the empty area is roughly judged by listening to the sound and identifying the position, so that the result is high in subjectivity, incapable of being quantified and low in efficiency, and has great safety risk for high-altitude elevation detection. The drawing method belongs to local damage detection, and although the bonding strength can be quantitatively measured, the original structure is damaged, and only sampling inspection can be performed, so that comprehensive census cannot be realized.
