Description

  The present invention relates to an apparatus for processing lightweight cellular concrete in which a side wall of a groove provided on the surface of lightweight cellular concrete is peeled off with a blade and a natural tone (stone split tone, grain tone) appears.

  The lightweight cellular concrete panel is a lightweight prefabricated panel reinforced with reinforcing reinforcing bars and the like, and the size thereof is known as a large panel having a width of 60 cm and a length of several meters, for example. Such lightweight cellular concrete panels have the characteristics of being economical, lightweight, fire-resistant and heat-insulating, and excellent in workability. In the construction industry, individual houses, houses with stores, building roofs, floors, outer walls In addition, it is frequently used as a partition material.

  However, lightweight cellular concrete panels are building materials with such excellent properties, but because of their production efficiency, they are generally produced as panels with a flat flat surface. There are drawbacks.

  In order to solve this problem, a method for forming a groove on the lightweight cellular concrete panel surface has been proposed. For example, Patent Document 1 and Patent Document 2 disclose surface processing techniques using a rotary cutting blade, but those obtained by grooving with these techniques have a mechanically uniform design. In addition, since the shape composed of the surface and the groove portion is relatively sharp, if the side portion is damaged due to impact during transportation and enforcement, the essential problem such that this damage is conspicuous Is left.

  Patent Document 3 discloses a technique for obtaining a concave portion, that is, a groove portion by colliding a projection material such as a small hard sphere with the surface of a lightweight cellular concrete panel using an emperor unit. Is abruptly completed, and it is easy to be damaged due to impacts during transportation and operation, and the surface properties of the damaged part and the processed surface with small steel balls are different. Has been.

Further, as in Patent Document 4 and Patent Document 5, even when processing with a small steel ball and grooving with a blade are used in combination, it is inevitable that the side surface of the groove is steep, and impact during transportation and enforcement is unavoidable. The essential problems remain, such as being easily damaged, and the nature of the damaged portion being different from that of the other surface, so that the post-damage is easily noticeable.
