Description

TECHNICAL FIELD

[0002] In the field of building construction and decoration, the chamfer processing of steps is an important work. Good chamfer not only can improve the appearance of steps, but also can reduce the collision risk of personnel when walking and increase safety. However, in the current construction process of step chamfer, the following problems still exist:

[0003] Precision is difficult to guarantee: the traditional chamfer method mainly relies on the manual operation of workers, and the chamfer is made according to experience, which makes it difficult to unify the size and angle of chamfer, and the precision is low. The operation level of different workers is quite different, which easily leads to uneven chamfer quality. Low efficiency: manual chamfering needs to consume a lot of time and energy, especially in large-scale construction projects, the chamfering work becomes an important factor affecting the construction progress. Workers need to measure and adjust repeatedly, the operation is complicated, and the efficiency is not high. Safety risk: when performing manual chamfering, workers need to use some electric tools such as angle grinder, improper operation can easily cause safety accidents. Moreover, long-time manual operation is easy to make workers tired, which increases the safety hazard.

[0004] A large venue stand surface layer chamfer control plate is disclosed in Chinese patent with publication number CN202321706353, which comprises a positioning plate and a forming plate.
