Description

Technical Field

[0002] Over the past few decades, with the continuous development of roofing materials, from rigid waterproofing to flexible waterproofing, there have been several generations of waterproofing materials and methods. However, the problem of roof leakage has not been completely solved. With the increase of housing in recent years, the problem of roof leakage has become more and more prominent, which has brought great trouble to the lives of residents. One of the treatment methods used today is to manually apply mortar with an iron trowel to the inner corner of the roof base to form an arc angle for treatment.

[0003] For example, patent CN202969881U discloses a new iron trowel for building plastering, including a bottom plate, a handle for holding the iron trowel at the top of the bottom plate, a bubble observation window of a level tube at the front end of the handle, and a bubble in the center of the bubble observation window of the level tube. The utility model has a simple structure, and when performing ground plastering construction and leveling, a ruler is not required, and the position of the bubble in the bubble observation window of the level tube at the front end of the iron trowel can be observed. The iron trowel itself can be used for leveling while plastering, which saves construction time and improves construction efficiency.

[0004] The side of the existing iron trowel that contacts the wall is flat, and it can be used for general construction. However, when the mortar needs to be made into an arc corner, it is very limited by the operator's usage technique.
