Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to an exterior wall treatment device and a reconstruction method for old buildings. Background Art

[0002] In recent years, with the acceleration of urbanization and the advancement of the renovation of old communities, there are some old buildings in the city that have been in use for a long time, which need to be reinforced or demolished after inspection. However, due to the nature of the land and planning conditions, some buildings cannot be demolished and rebuilt, so they need to be renovated, including polishing and refurbishing some of the exterior walls of old buildings.

[0003] The quality of building exterior wall construction is directly related to whether the functions of the building exterior wall can be performed normally, and ultimately affects whether the entire building can be used normally. The quality of building exterior wall construction will also affect the performance and appearance of the building facade. During the construction of the building exterior wall, the wall is generally polished to facilitate the subsequent waterproofing and spraying construction. Many existing wall treatment devices for building exterior wall construction cannot conveniently adjust the polishing height and horizontal polishing position of the wall when in use, affecting the use effect. When polishing the wall, more floating dust will be generated, which makes it inconvenient to collect the polished waste, and the polishing disc is prone to damage during long-term use and is not convenient to replace.
