Description

  The present invention relates to a block used as a material such as an outer wall of a building or a fence.

  Conventionally, the outer wall and block wall of a building are generally constructed by stacking a number of concrete blocks. However, the color and appearance of a concrete block are not suitable for the exterior of the building, so a residential building, etc. It was rarely used for outer walls that required decorativeness. On the other hand, for example, a brick outer wall often used in European architecture has a magnificent appearance due to the unique color and texture of bricks and is preferred as an outer wall that requires decorativeness.

  Therefore, it is known that a brick block having the same shape as a concrete block is stacked to constitute an outer wall or a fence of a building (for example, see Patent Document 1).

  By the way, bricks are made by mixing sand, lime, etc. with clay, kneaded into a rectangular shape, dried and then baked in a kiln, so the normal temperature bending strength is high, but on the other hand, stress concentration , The fracture toughness is lowered and cracks are likely to occur. For this reason, when it used for the outer wall of a building, there existed a problem that the appearance of an outer wall was impaired by the crack of the brick surface.

  This invention is made | formed in view of the said problem, The place made into the objective is to provide the block which can suppress generation | occurrence | production or expansion of the crack in the surface even if it is a product made from a brick.

In order to achieve the above object, the present invention provides a block in which a block main body is formed of bricks, and a plurality of vertical grooves and a plurality of horizontal grooves are provided in a lattice shape on the surface of the block main body, and every predetermined number of the grooves. The predetermined groove to be arranged is formed so that the width dimension and the depth dimension are larger than those of the other grooves. As a result, since a plurality of grooves are provided in a lattice shape on the surface of the block body, even if cracks occur on the surface of the block body, the growth of cracks is prevented by the grooves, or the cracks pass through the grooves. Since it extends along the groove, cracks on the surface of the block body do not stand out. In this case, since the grooves arranged every predetermined number of the grooves are larger in width and depth than the other grooves, cracks generated on the surface of the block body due to drying mainly occur in the width and depth. It is suppressed by a groove having a small dimension, and cracks generated from the inside of the block main body due to bending stress or impact are mainly suppressed by a groove having a large width dimension and depth dimension.

According to the present invention, since the block main body is formed of bricks, a high-quality appearance can be obtained by the color and texture peculiar to bricks, such as brick outer walls used in, for example, European architecture. There is an advantage that it is preferable as an outer wall of a building. In addition, even when cracks occur on the surface of the block body, the generation or expansion of cracks on the surface of the block body can be suppressed by the grooves, so that cracks on the surface of the block body do not stand out and There is an advantage that the appearance is not impaired. In this case, cracks generated on the surface of the block body due to drying are mainly suppressed by grooves having small width and depth dimensions, and cracks generated from the inside of the block body due to bending stress and impact are mainly of width and depth dimensions. Since it can suppress by a large groove | channel, generation | occurrence | production or expansion of a crack can be suppressed more effectively.

  FIG. 1 to FIG. 6 show an embodiment of the present invention, which shows a block used as a material for an outer wall of a building or a fence, for example.

  The block of this embodiment includes a rectangular parallelepiped block main body 1 made of bricks, and the block main body 1 is formed in the same shape as a general concrete block. That is, the block main body 1 is formed to have the same size as a standard known concrete block (for example, the width dimension A is 390 mm and the height dimension B is 190 mm). It has a plurality of holes 2 for doing this. The holes 2 are formed so as to penetrate the upper and lower surfaces of the block body 1 in the vertical direction, and are arranged at intervals in the width direction of the block body 1. Further, notches 3 each having a half shape in the width direction of the hole 2 are provided on both side surfaces of the block body 1 in the width direction.

  A plurality of vertical grooves 4 and a plurality of horizontal grooves 5 are provided in a lattice pattern on the front surface and the back surface of the block body 1, and the vertical grooves 4 and the horizontal grooves 5 are arranged at equal intervals P (for example, 10 mm to 20 mm). Yes. In this case, among the vertical grooves 4 and the horizontal grooves 5, the vertical grooves 4 ′ and the horizontal grooves 5 ′ arranged every predetermined number (for example, 5) are wider and deeper than the other vertical grooves 4 and horizontal grooves 5. Is getting bigger. That is, the vertical groove 4 and the horizontal groove 5 having a small width dimension and depth dimension are formed, for example, with a groove width W1 of 1 mm to 3 mm and a groove depth D1 of 0.5 mm to 1.5 mm. The large vertical groove 4 'and horizontal groove 5' are formed, for example, with a groove width W2 of 4 mm to 8 mm and a groove depth D2 of 2 mm to 4 mm. Although FIG. 4 shows a plan sectional view of the main part of the block main body 1, the cross-sectional shape of the groove is the same in the side cross section of the block main body 1.

  The block is manufactured by mixing sand, lime, and the like with clay, which is a brick material, molding it into a rectangular shape, drying it, and baking it in a kiln. In this case, by using a mold in which protrusions corresponding to the vertical grooves 4, 4 'and the horizontal grooves 5, 5' are provided on the inner surface, the vertical grooves 4, 4 'and the horizontal grooves 5, 5 are formed during the molding. 5 'can be formed.

  When constructing the outer wall of the building using the block configured as described above, a plurality of blocks are stacked, and a reinforcing bar and a pipe are inserted into the hole 2 and the notch 3 of the block body 1 as necessary. Fill with concrete or mortar. Thereby, for example, as shown in FIG. 6, a brick-like outer wall surface is formed on the building by the front surfaces of the plurality of block main bodies 1.

The crack C on the surface of the block body 1 is not noticeable. In this case, cracks C generated on the surface of the block main body 1 by drying are mainly suppressed by the vertical grooves 4 and the horizontal grooves 5 having a small width dimension and depth dimension, and cracks C generated from the inside of the block main body 1 due to bending stress or impact. Is mainly suppressed by the longitudinal groove 4 'and the transverse groove 5' having a large width dimension and depth dimension.

  Thus, according to the block of this embodiment, since the block main body 1 is formed of bricks, for example, a brick exterior wall used in European architecture or the like, the appearance is high-quality due to the unique color tone and texture of bricks. For example, there is an advantage that it is preferable as an outer wall of a residential building.

  In addition, since a plurality of vertical grooves 4 and 4 ′ and horizontal grooves 5 and 5 ′ are provided in a lattice shape on the surface of the block body 1, even if a crack C occurs on the surface of the block body 1, the crack C Occurrence or expansion of the outer wall can be suppressed by the vertical grooves 4 and 4 ′ and the horizontal grooves 5 and 5 ′, and the appearance of the outer wall is not impaired by the crack C.

  In this case, among the vertical grooves 4 and the horizontal grooves 5, the vertical grooves 4 ′ and the horizontal grooves 5 ′ arranged every predetermined number have larger width and depth dimensions than the other vertical grooves 4 and the horizontal grooves 5. Therefore, the crack C generated on the surface of the block main body 1 due to drying is mainly suppressed by the vertical groove 4 and the horizontal groove 5 having a small width dimension and depth dimension, and the crack C generated from the inside of the block main body 1 due to bending stress or impact is mainly used. In addition, since the vertical grooves 4 ′ and the horizontal grooves 5 ′ having large width dimensions and depth dimensions can be suppressed, the generation or expansion of cracks C can be suppressed more effectively.

  Further, the block main body 1 is stacked with another block main body 1 to form a rectangular parallelepiped shape that can form a wall of a building or the like, and each vertical groove 4, 4 ′ and each horizontal groove 5, 5 ′ are formed on the surface of the block main body 1. Since it was provided on the surface to be the outer wall surface, it is possible to form a brick-like outer wall surface by the surface of the block body 1 by stacking in the same manner as the concrete block, which is extremely advantageous when used for a building wall or a fence. is there.

  Furthermore, since the block body 1 is provided with a plurality of holes 2 penetrating in the vertical direction, it can be reinforced by inserting reinforcing bars in the holes 2 or pipes can be inserted into the holes 2 as in the concrete block. It is extremely advantageous when converting.
