The invention discloses grid scribing equipment for a bridge detection rebound test, which comprises a device box and a handle fixedly connected with the bottom of the device box, wherein a through hole is formed in the middle of the top of the device box, a feeding assembly used for conveying rubbing dye is arranged in the device box, the feeding assembly is provided with a one-way positioning assembly used for conducting quantitative control on the rubbing dye, and a rubbing plate used for conducting grid rubbing on the bridge is arranged at the position, which is located right above the feeding assembly, in the device box. According to the invention, a user moves the device box upwards, an abutting rod can be driven to descend, when the abutting rod descends, the rubbing plate can be firstly driven to rotate by 180 degrees, the rubbing surface of the rubbing plate is changed from facing downwards to facing upwards, and then the abutting rod continues to descend to drive the rubbing plate to move upwards by a certain distance till the rubbing plate makes contact with the bridge surface and conducts grid rubbing on the bridge surface, so that the trouble of manually drawing grid lines is avoided, a user only needs to hold the handle by hand to push the device box upwards, and convenience and rapidness are achieved.
Description
technical field [0001] The invention relates to the technical field of bridge detection, in particular to a bridge detection springback test grid scribing device. Background technique [0002] With people's attention to engineering quality and the rapid development and maturity of non-destructive testing technology, the application of non-destructive testing technology in construction projects is increasing. The rebound test using the rebound tester has not only become one of the detection and analysis methods of engineering accidents, but also is becoming a reliable monitoring tool in the process of engineering quality control and building use. It can be said that in the construction, acceptance and use of the project Each has its place. [0003] Due to the particularity of bridge construction, the rebound method can only be used for non-destructive testing of strength when testing it, so that the failure stress value can be obtained without destroying the bridge structure...
