Description

  The present invention relates to a building concrete block (stacking block) mainly used for constructing a wall such as a concrete fence.

  Generally, a fence used as an enclosure for a house or site is constructed by stacking a plurality of concrete blocks, and as such a stack block, a hollow concrete block having an oval through hole drilled in the height direction is often used. (For example, Patent Document 1).

  In particular, this type of concrete block has a rectangular outline with a large width compared to its height, and both end faces on the short side thereof have a U-shape that is the same shape as the through hole by abutting the end faces. Are formed.

  Further, as such a hollow concrete block, there is known one in which a dimension between inner walls of a groove (concave portion) formed on an end surface is made larger in a back side portion than an entrance portion (for example, Patent Document 2).

  Then, according to the concrete blocks as described above, the blocks are sequentially stacked on the concrete foundation, and the reinforcing bars extending from the top surface of the concrete foundation are passed through the through holes of each block, and mortar or concrete is filled in the through holes. By doing so, a tough wall can be constructed.

  However, the hollow concrete blocks disclosed in Patent Documents 1 and 2, etc. were constructed by merely forming through holes in the concrete block body for the purpose of reducing the weight and inserting reinforcing bars. The wall of the wall is flat and unobtrusive.

  In addition, since the above-mentioned conventional concrete block is a smooth concrete surface on both front and back sides, the walls such as walls constructed by this are very artificial and have a feeling of pressure and poor design. Met.

  In addition, there are things with designs such as stripes on both the front and back sides of the block body, but it is possible to construct only a uniform wall body that does not change even if that kind of block can be stacked without worrying about the front and back sides. Can not.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a novel concrete block capable of constructing a wall body rich in change.

  In order to achieve the above object, the concrete block according to the present invention is characterized in that different designs are applied to the front and back surfaces of a concrete block main body having a polygonal outline.

  Preferably, a plurality of concave grooves are formed in parallel on the front and back surfaces of the block main body at a predetermined interval, and either one of the front and rear surfaces of the block main body has a gap between the concave grooves. A plurality of design grooves having a shallow bottom are formed in parallel with the concave grooves, and the other surface of the block body is formed of irregular irregularities imitating a split surface of natural stone between the concave grooves formed on the surface. It is characterized by a split skin surface.

  Further, the block main body has a rectangular outline, and U-shaped groove portions are formed on both end surfaces on the short side along the length direction of the end surface.

  According to the concrete block according to the present invention, since different designs are applied to the front and back surfaces of the concrete block main body having a polygonal outline, it is possible to build a quaint wall body by stacking the block main bodies. In addition, different types of wall bodies can be constructed with one type of block body by different designs on the front and back surfaces.

  In particular, it is very aesthetic because a plurality of design grooves shallower than the concave grooves are formed in parallel between the concave grooves on either one of the front and back surfaces of the block body. Since the other surface is a split skin surface made of irregular irregularities imitating the split surface of natural stone between the grooves formed in the surface, it can form a wall surface that does not resemble an artificial structure. .

  In addition, since the U-shaped grooves are formed on both end faces of the block main body having a rectangular outline, it is possible to construct a strong wall body by firmly joining adjacent block main bodies.

  The present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing a concrete block according to the present invention, and FIG. 2 is a plan view of the concrete block. 1 and 2, reference numeral 1 denotes a block body made of concrete (especially lightweight concrete) having an oblong rectangular outline. In this example, the width W is about 390 mm, the height H is about 190 mm, and the thickness. T is set to about 120 mm.

  The block main body 1 constitutes a building block (a hollow concrete block) for constructing a wall body such as a concrete fence, and the block main body 1 has an elliptical penetration extending from its upper end surface to its lower end surface. A plurality of holes 2 (three in the illustrated example) are formed, and U-shaped grooves 3 having half the size of the through-holes 2 along the length direction are formed on the opposite end surfaces on the short side. It is formed. In this example, the upper end surface of the block main body 1 is a smooth surface. However, a lateral groove (for passing the reinforcing bar in the lateral direction) having the same shape as the groove portion 3 may be formed in the portion.

  A plurality of concave grooves 4 extending in the vertical direction are formed in parallel on the front and back surfaces 1A and 1B of the block main body 1 at predetermined intervals.

  The concave groove 4 is formed integrally with the block body 1 by filling the molding die of the block body 1 with fresh concrete. However, after the block body 1 is molded, the front and back surfaces 1A and 1B are partially cut. Thus, the concave groove 4 can be formed.

  In this example, seven concave grooves 4 are formed on the surface 1A of the block main body 1 at intervals of about 50 mm, and five concave grooves 4 are formed on the back surface 1B of the block main body 1 at intervals of about 67 mm. However, the number and interval of the concave grooves 4 may be the same on the front and back surfaces 1A and 1B of the block body 1.

  3 is a schematic front view showing the front side of the block main body, FIG. 4 is a schematic rear view showing the back side of the block main body, and FIGS. An enlarged section is shown.

  As apparent from these drawings, the front surface 1A and the back surface 1B of the block body 1 are provided with different designs (design patterns) including the concave grooves 4 having different numbers.

  In particular, as is apparent from FIGS. 3 and 5, the surface 1 </ b> A of the block body 1 has a split skin surface 5 between the concave grooves 4. The split skin surface 5 is an undulating surface made of irregular irregularities that imitates the split surface of natural stone, and the height difference is set to about 5 mm. Such a split skin surface 5 can be formed by shot blasting or using a molding die molded from natural stone.

  On the other hand, as apparent from FIGS. 4 and 6, a plurality of design grooves 6 having a shallower bottom than the recessed grooves are formed between the recessed grooves 4 on the back surface 1 </ b> B of the block body 1. Each design groove 6 is a linear thin groove formed in parallel along the concave groove 4, and a plurality of ridges 7 having substantially the same width as the design groove 6 are formed therebetween. Since a plurality of design grooves 6 are formed between the recessed grooves 4, the interval is smaller than the interval between the recessed grooves 4 on the back surface 1 </ b> B of the block body 1.

  And according to the concrete block of this invention comprised as mentioned above, as shown in FIG. 7, the block body 1 can be piled up sequentially on the concrete foundation 10, and the wall 11 surrounding a house etc. can be constructed | assembled.

  Here, not-shown reinforcing bars (vertical bars) extending from the upper end of the concrete foundation 10 are passed through the through holes 2 of each block body 1, and mortar or concrete is filled in the through holes 2. The

  7 omits the design on the front and back surfaces 1A and 1B of the block body 1, the block body 1 is stacked such that the surface 1A is inside the wall body 11, for example. Therefore, the taste can be changed between the inside and the outside of the constructed wall body 11 by different designs on the front and back surfaces 1A and 1B of the block body 1.

  In addition, by constructing the block main body 1 by turning it upside down one by one, stacking it upside down and arranging it by flipping the front and back one row at a time, it is possible to construct a variety of wall bodies 11 that are rich in change while using one type of block main body 1. Is possible.

  As mentioned above, although the suitable example of the concrete block which concerns on this invention was demonstrated, the design pattern in the front and back both surfaces 1A and 1B of the block main body 1 is not restricted to the said example, The front and back both surfaces 1A and 1B of the block main body 1 of the ditch | groove 4 You may change the direction. For example, as shown in FIG. 8, the groove 4 extending in the vertical direction may be formed on the front surface 1A of the block body 1, and the groove 4 extending in the horizontal direction may be formed on the back surface 1B. In addition, also in FIG. 8, the space between the concave grooves 4 can be used as a split skin surface on at least one surface side.

  Here, if a good example of the design pattern is shown in FIG. 9 and described, (A) is a first design pattern in which a plurality of concave grooves 4 extending in the vertical direction are formed at predetermined intervals in the horizontal direction, (B ) Is a second design pattern in which the interval between the concave grooves 4 is smaller than that of the first design pattern, and (C) is a plurality of concave grooves 4 that extend in the vertical direction and are formed at predetermined intervals in the horizontal direction. A third design pattern having a split skin surface 5 between the grooves 4, (D) shows a plurality of concave grooves 4 extending in the vertical direction at predetermined intervals in the horizontal direction, and a dotted line between the concave grooves 4 A fourth design pattern in which a plurality of design grooves 6 shown in FIG. 6 are formed, (E) is a fifth design pattern in which concave grooves 4 extending in the vertical direction are formed in a dense state only in the center of the surface, and (F) is a horizontal pattern 6th design pattern which formed several ditch | groove 4 extended in the direction at predetermined intervals in the vertical direction, (G) 5 and a seventh design pattern, in the present invention may be applied to two types of front and back surfaces 1A, 1B of the design pattern block body 1 which is selected from among those design pattern. In addition, as a suitable combination of two types of design patterns, AB, AC, AD, AF, AG, BC, BD, BF, BG, C -D, CE, CF, CG, etc. are mentioned.
