Abstract

The invention discloses a precast concrete member surface roughness quantitative detection device. The device includes a shell (1), a lifting driver (2) and a squeezing board (3), the shell (1) is provided with a through hole (11), a detection needle (12), a conductive protrusion (13), a groove (14), a sliding resistor (15), a constant voltage power supply (16) and a current collector (17), and the bottom of the squeezing board (3) is provided with a plurality of elastic rods (4). The method provided by the invention can automatically and rapidly obtain a numerical value of the surface roughness of a prefabricated structural member.

Description

technical field [0001] The invention relates to the technical field of building detection, in particular to a quantitative detection device for surface roughness of prefabricated concrete components. Background technique [0002] Prefabricated buildings refer to industrialized buildings that are produced and processed in factories and assembled on site as much as possible. Prefabricated components such as laminated floor slabs, laminated beams, and laminated wall panels in the prefabricated concrete structure are made with rough surfaces on the joint surface to enhance the bonding force between the old and new concrete, ensure common stress, and ensure the quality and safety of the prefabricated concrete structure. play a key role. Article 9.2.8 of the "Code for Construction Quality Acceptance of Concrete Structure Engineering" (GB50204-2015) issued by the Ministry of Housing and Urban-Rural Development of the People's Republic of China stipulates that the quality of the ro...
