Description

  The present invention relates to a brick.

  Conventionally, for example, when a flower bed or the like is formed using a rectangular parallelepiped brick, the bricks are sequentially arranged and stacked at predetermined positions while a mortar or the like is interposed between the bricks. This work requires a certain level of skill for the worker. Therefore, Patent Document 1 proposes a brick provided with a fitting convex portion and a fitting concave groove on the upper and lower surfaces so that the stacking operation can be easily performed.

JP 2002-88945 A

  However, in Patent Document 1, when the fitting protrusion of one brick is fitted into the fitting groove of another brick, the position of the fitting protrusion in the fitting groove is not determined, and the bricks are stacked. Misalignment may occur between bricks. In addition, when the mating projections are circular in plan view and do not have directionality, other bricks stacked with the mating projections as the starting point rotate and move, resulting in misalignment between the bricks. There is.

  The present invention has been made in view of such a background, and can easily and accurately perform stacking work without the need for inclusions such as mortar, and suppress misalignment during and after the stacking work. It is intended to provide bricks that can be made.

  The brick of the present invention is a brick having a first main surface and a second main surface on one side and the other side in the thickness direction, and is formed so as to protrude in the thickness direction from the first main surface. A pair of protrusions arranged side by side, and a pair of recesses formed in such a manner that the protrusions can be fitted into the second main surface so as to be recessed in the thickness direction, and are arranged side by side in the length direction. The convex portion includes a first projecting portion projecting on one side in the length direction, a second projecting portion projecting on the other side in the length direction, and a third projecting portion projecting on one side in the width direction, It has the 4th protrusion part which protrudes in the other side of the width direction, It is characterized by the above-mentioned.

  The brick has a pair of convex portions on the first main surface and a pair of concave portions on the second main surface. And a recessed part is a shape which can fit a convex part. Therefore, the bricks can be stacked without requiring inclusions such as mortar between the bricks by fitting the convex part of one brick into the concave part of the other brick. As a result, it is possible to easily and easily perform the brick stacking work without requiring skill of the operator. Further, if the volume of the concave portion is made larger than the volume of the convex portion, the weight of the brick can be reduced, and the bricks can be easily stacked even by women and children.

  Moreover, the convex part has the 1st protrusion part and 2nd protrusion part which protrude in a length direction, and the 3rd protrusion part and 4th protrusion part which protrude in the width direction. That is, a convex part has four protrusion parts which have directionality. Therefore, by fitting the convex part of one brick into the concave part of another brick, it is possible to accurately perform the stacking work of the bricks and to suppress the positional deviation between the bricks during and after the stacking work. In addition, since other bricks can be arranged and stacked with respect to one brick in the same direction or orthogonal to the brick, the bricks can be accurately stacked in a predetermined direction.

  Thus, according to the present invention, there is provided a brick capable of easily and accurately performing a stacking operation without requiring inclusions such as mortar, and capable of suppressing misalignment during and after the stacking operation. be able to.

  Further, in the brick, as described above, the projecting portions are the first projecting portion and the second projecting portion projecting in the length direction, and the third projecting portion and the fourth projecting portion projecting in the width direction. And have. Here, “projecting in the length direction” means that when the vector in the projecting direction is divided into a vector component in the length direction and a vector component in the width direction, the vector component in the length direction is the vector component in the width direction. Than that. Further, “projecting in the width direction” means that the vector component in the width direction is larger than the vector component in the length direction.

  In the brick, the side surfaces of the first protrusion, the second protrusion, the third protrusion, and the fourth protrusion of the protrusion may be formed in a curved surface shape. In this case, damage such as chipping or cracking of the brick can be suppressed. That is, since brick is a ceramic baked at a high temperature, damage such as chipping or cracking due to contact is likely to occur particularly at corners. Therefore, damage such as chipping or cracking of the brick can be suppressed by making the side surfaces of the four projecting portions provided on the convex portions curved.

  In the brick, the convex portion may include a plurality of the first projecting portion, the second projecting portion, the third projecting portion, and the fourth projecting portion. In this case, it is possible to further suppress the positional deviation between the bricks during and after the stacking operation. In addition, bricks can be stacked more accurately.

  Moreover, the shape of the said convex part may have 90 degree rotational symmetry in planar view. In this case, it is possible to more accurately perform the work of stacking other bricks by placing them in the same direction or perpendicular to the brick, and between the bricks during and after the stacking work. Misalignment can be sufficiently suppressed.

  Further, the brick may be provided with a through hole that is formed so as to penetrate in the thickness direction and through which a support member that supports the brick is inserted. In this case, the bricks can be stacked while the support member is inserted into the through-hole of the brick, and the stacked bricks can be reliably supported by the support member. Thereby, even if the number of stacked stages increases, bricks can be stacked easily and accurately. Moreover, the positional shift between bricks can be sufficiently suppressed.
