Description

Technical Field

[0001] The utility model relates to the technical field of a smoothing device, in particular to a building wall smoothing device. Background Art

[0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. At present, after the pouring of frame structure buildings, a thin layer of concrete is usually applied on the exterior wall. It is directly applied to the wall to strengthen the wall. After the concrete is applied on the exterior wall, a smoothing device is needed to smooth the concrete.

[0003] A Chinese patent discloses a building wall smoothing device (application number: 202222863802.8). The solution uses an antenna, a signal receiver and a central processor inside a control box to remotely control the device, which is convenient for the control of the device. Through a scraper, the concrete can be smoothed when the device moves, reducing labor intensity and improving smoothing efficiency. Although the device can be remotely controlled for smoothing work, the smoothing device of the device cannot achieve height adjustment and cannot adapt to smoothing work of multiple specifications. At the same time, the scraper of the device cannot achieve angle adjustment, resulting in it being able to only perform smoothing work on conventional horizontal walls. It is not practical and will increase the cost of smoothing work. Utility Model Content
