Surface flatness detection device for building inner wall body

Abstract

The invention discloses a surface flatness detection device for a building inner wall body. The device comprises a detection box and a handle rod, wherein the interior of the detection box is rotatably provided with a rotating roller through a transverse shaft, a first cavity and a second cavity are respectively in communication with a first air hole and a second air hole, the outer surface of thedetection box is provided with a scale box and a power box, the scale box and the detection box are connected, the handle rod installed on the surface of the detection box is arranged below the scalebox, and an air pump is installed on the detection box. According to the surface flatness detection device for the building inner wall body, wall surface protrusions can cause air pressure change inthe rotating roller in a mode that the rotating roller rotates, so that the wall surface tiny protrusions are conveniently detected on the basis of the air pressure transmission principle and an air pressure conversion structure, and meanwhile, a detection frame can be used for detecting a sunken area of the wall surface and marking in real time, so that the detection efficiency of the wall surface flatness is greatly improved.

Description

technical field [0001] The invention relates to the technical field of building detection, in particular to a surface flatness detection device for building inner walls. Background technique [0002] In the building structure, the wall structure is the foundation and the main structure. After the wall structure and the building as a whole are completed, the surface of the inner wall needs to be painted or decorated twice. Unevenness will affect the installation of other decorative structures and the service life of subsequent decoration materials. Therefore, it is necessary to use corresponding detection devices to detect the flatness of the wall surface. However, the existing similar devices have the following problems in actual use. question: [0003] Wall flatness detection is generally carried out by means of light source detection. The protruding part of the wall will cause the normal transmission of light, thus helping the user to see the protruding position intuitive...

Problems solved by technology

[0004] The object of the present invention is to provide a surface flatness detection device for building interior walls, to solve the above-mentioned background technology that the wall flatness detection generally uses light source detection to carry out illumination detection, and the wall surface is convex. The location will lead to the normal transmission of light, thereby helping users to see the raised position intuitively, but limited by objective factors such as the thickness of the device itself, some small protrusions on the wall cannot be easily detected, resulting in unsatisfactory detection results The problem
