Abstract

The invention relates to a concrete carbonized protective layer bonding strength detector. The concrete carbonized protective layer bonding strength detector comprises a table board (2). A lifter (3) is arranged on the table board. A lifting threaded rod (4) is arranged on the lifter in a matched mode. An adhesion plate (10) is arranged below the table board. The lifting threaded rod penetrates through the table board and is matched with the adhesion plate. The periphery of the table board (2) is provided with a set of adjusting threaded rods (6). The lower end of each adjusting threaded rod is provided with a supporting leg (1) in a rotating fit mode. The bottom of each supporting leg (1) is provided with a suction cup (9). By the adoption of the technical scheme, the concrete carbonized protective layer bonding strength detector has the advantages of being simple in structure, convenient to operate, small in testing result error, applicable to a construction site and the like.

Description

Technical field: [0001] The invention relates to a test device for the bond strength of a protective layer, in particular to a detector for the bond strength of a concrete carbonized protective layer. Background technique: [0002] After hydraulic structures are put into operation, different phenomena of aging and disease will inevitably appear. For example, 10 years after the sluice is built, the concrete of the gate piers, working bridges, pedestrian bridges and other parts will be obviously carbonized, and the pedestrian bridge slab may have steel rust expansion joints due to the thin protective layer of steel bars. The most widely used treatment method at this stage is to apply protective materials on the concrete surface, such as SBR mortar or protective coatings such as epoxy coatings and chlorosulfonated polyethylene coatings. The quality of the coating is finally reflected in the coating film. Therefore, the quality inspection after painting is mainly to detect the ...
