Technical Field
[0001] The utility model relates to the technical field of building construction inspection, and more specifically, to a novel device for quickly detecting the sagging of plaster for rendering Background Art
[0002] Wall rendering refers to the surface layer project of applying cement mortar, mixed mortar, and lime mortar on the wall. The indoor and outdoor wall rendering work is carried out after the completion of the building structure construction. Scientific rendering work can play functions such as moisture-proof, weathering-proof, and heat-insulating, and prevent the building wall from being eroded by wind, rain, snow, etc. The concrete wall surface constructed by the large formwork is smooth and flat, but at the joints of the vertical and horizontal walls, the joints between the upper and lower floors of the staircase, and the door and window openings of the wall constructed by the large formwork, the wall surface needs to be plastered and straightened. The phenomenon that the paint liquid leaves a flowing trace downward on the coating film is called sagging. It mostly appears on the vertical surface or at the corners. Generally, the sagging in the vertical surface is in the shape of a hanging curtain, and the sagging at the corners is in the shape of a tear mark. Sagging will occur if the applied paint film is too thick or the paint is too thin.
[0003] At present, the detection of the sagging problem of plaster for rendering mainly depends on visual inspection by experience after smearing, which not only affects the detection efficiency, but also a large amount of sagging will affect the aesthetics of the rendering. Therefore, we propose a novel device for quickly detecting the sagging of plaster for rendering to solve the above problems. Content of the Utility Model

[0008] An internal thread sleeve is screwed on the threaded column. A pressing plate closely attached to the inelastic cotton thread is fixedly connected to the end of the internal thread sleeve. Rotating handles are symmetrically and fixedly connected to the outer wall of the internal thread sleeve.
[0009] Further, a wire winding groove is provided at the root where the threaded post is connected to the connecting shaft, and the end of the inelastic cotton thread is wound and connected to the wire winding groove.
[0010] The wire winding groove corresponds to the notch of the guide rail groove.
