Building wall surface roughness detection device

Abstract

The invention discloses a building wall surface roughness detection device, and relates to the technical field of building construction detection. The device comprises a base, wherein a pressure tankand a compressor are arranged on the base; a telescopic column is further arranged on the base, a fixed plate is arranged on the telescopic column, a guide telescopic piece is arranged on the fixed plate, a bin body is arranged at the end of the guide telescopic piece, and a horizontal plate and an inclined plate are arranged on each of the two sides of the bin body; end plates are further arranged at the ends of the horizontal plate and the inclined plate. A vertical plate which is vertically arranged is further arranged on the outer side of the end part of the inclined plate; pneumatic ejection mechanisms are further arranged on the two sides of the bin body, and pressure detection mechanisms are arranged on the inner side faces of the end plates. A sliding block is arranged in an area defined by the horizontal plate and the inclined plate in a matched mode. By means of the detection mechanism composed of the sensor, the sliding block and the like, the roughness of the wall surface is detected through physical knowledge, the problems that manual deviation exists in a visual inspection method, and the interface processing roughness effect cannot be accurately represented are solved, and the roughness detection accuracy and precision are improved.

Description

technical field [0001] The invention belongs to the technical field of building construction detection, and in particular relates to a device for detecting the roughness of a building wall surface. Background technique [0002] In building plastering engineering, the hollowing and cracking of the mortar layer is a common building problem, and the quality of the interface treatment of the base surface plays a crucial role in the hollowing and cracking of the mortar. The base surface becomes rough after the interface treatment, so that the mortar can be firmly bonded to the base surface, so as to avoid the hollowing and cracking of the mortar during the drying and shrinkage process (especially the smooth concrete base surface), so the quantitative measurement of the interface roughness measurement becomes very important. The existing industry standard JGJ / T223 "Technical Regulations for the Application of Ready-Mixed Mortar" has corresponding regulations on the acceptance of ...
