Description

  The present invention relates to a concrete letter block used for exteriors and interiors, and more particularly to a concrete letter block capable of forming a character string by combining a plurality.

  Traditionally, if you want to attach a character string such as a nameplate instead of a nameplate or a welcome word to a concrete block that constitutes a fence or a concrete block that constitutes the edge of a flower bed at the front door, the character string is engraved directly on the block It was. In recent years, concrete blocks are often used for interiors, but when a character string is to be attached to such a block, the character string is directly carved on the block.

  However, it is difficult for ordinary users to carve concrete, so there is a problem that a character string cannot be easily formed and used for an exterior or interior.

  The present invention solves the above-described problems, and an object of the present invention is to provide a block with a letter made of concrete that can be easily used for an exterior or interior by forming a character string.

  The block with letters of the present invention is made of concrete, is formed in a substantially rectangular parallelepiped shape, and is characterized in that only one letter is recessed on the front surface.

  Here, the block with letters of the present invention is preferably formed in a substantially cubic shape.

  Further, only one character may be recessed on the rear surface.

  Moreover, it is good also as a recessed part being provided in one side surface.

  Moreover, it is good also as a hole penetrated in an up-down direction.

  Since the block with characters of the present invention has only one character recessed on the front surface, a combination of a plurality can easily form a character string and use it for interiors and exteriors.

  Further, if the block with letters of the present invention is formed in a substantially cubic shape, the width does not change even if the side is front instead of the front. For this reason, when the character is not provided on the side surface, the side surface can be used to form the portion without the character, and when the character is also provided on the side surface, Or the like, it is possible to form different character strings, and convenience is improved.

  Further, if only one character is provided on the rear side, a character string can be formed on the back side, or a different character string can be formed by setting the rear side to the front, thereby improving convenience.

  Also, if a recess is provided on one side, when adhering side surfaces of adjacent blocks, if an adhesive is put into the recess, the blocks can be bonded together so that the adhesive is not visible from the outside. It is possible to create a block sequence that looks good.

  Further, if a hole penetrating in the vertical direction is provided, when a block with letters is used for the block rod, a reinforcing bar can be inserted into the hole, and the strength of the block with letters can be increased.

  A block 1 with letters (hereinafter abbreviated as “block 1”) according to a first embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the block 1 is made of concrete and is formed in a non-hollow substantially cubic shape having a side of about 80 mm.

  As shown in FIG. 1, the character 3 is recessed on the front surface 2 of the block 1. Corners 11 between the front surface 2 and the upper surface 9, the lower surface 10, the side surface 4, and the side surface 8 are chamfered to prevent chipping and are tapered.

  The side surface 4 of the block 1 is provided with a recess 5. The concave portion 5 has a substantially square shape (substantially square shape with one side of about 60 mm) smaller than the substantially square shape formed by the outer periphery of the side surface 4 in a side view. The peripheral wall 5 a of the recess 5 is a tapered surface that narrows toward the bottom 5 b of the recess 5.

  As shown in FIG. 2, characters 7 are recessed on the rear surface 6 of the block 1. The character 7 is different from the character 3, but of course, it may be the same character. Corners 12 between the rear surface 6 and the upper surface 9, the lower surface 10, the side surface 4, and the side surface 8 are chamfered and tapered to prevent chipping.

  The upper surface 9, the lower surface 10, and the side surface 8 are each planar.

  Next, the manufacturing method of the block 1 will be described. The block 1 is manufactured by pouring and solidifying concrete containing waste foundry sand, Portland cement, and aggregate into a metal mold. The purpose of using the waste foundry sand is to reduce the amount of waste and to protect the environment. Of course, concrete other than those described above may be used. In addition, in order to improve safety, the waste foundry sand is obtained by removing sodium silicate contained in the silicic acid-based foundry sand by overheating sublimation.

  The mold has a box shape having a front wall portion, a rear wall portion, both side wall portions, and a lower wall portion and opened upward. The front wall part and the rear wall part of the formwork are each a plurality of characters (for example, five when five blocks 1 are created at a time) so that a plurality of blocks 1 can be created at a time. It is composed of a board. Each character-attached plate is made of a casting and has a surface on which only one so-called mirror character in which left and right are reversed is raised. Each character-attached plate is replaceable, and the surface on which the mirror character is raised is used inward so that the mirror character is turned upside down. Moreover, the board in which the convex part corresponding to the recessed part 5 was formed in the inner surface is used for one side wall part of a formwork. As the other side wall portion and the lower wall portion of the mold, ones having a planar inner surface are used.

  And the inside of the formwork enclosed by these front wall parts, rear wall parts, both side wall parts, and a lower wall part is divided by a partition plate. For example, when five blocks 1 are created at a time, they are divided by four partition plates. Each partition plate has a convex portion corresponding to the concave portion 5 formed on one surface, and the other surface is flat.

  After pouring concrete into the mold and solidifying it, the mold is removed. The surface that was in contact with the lower wall portion of the formwork is the upper surface 9 of each block 1. Since the lower surface 10 of each block 1 is not in contact with the formwork, finishing for smoothing is performed, but a slight roughness is left. This is because when the lower surface 10 is used as an adhesive surface, the adhesive enters fine irregularities on the lower surface 10, so that the adhesive strength is improved.

  In this manufacturing method, it is necessary to create a plate with letters, but since the plate with letters can be used repeatedly, the block 1 can be mass-produced with inexpensive concrete, and the inexpensive block 1 can be provided.

  Next, a usage example of the block 1 will be described. FIG. 3 is an example in which the block 1 is arranged on the block wall 13. Here, a character string in place of the nameplate “NAGATA” is formed using six blocks 1. Further, on both sides of the block 1 forming the character string, the block 1 with the side surface 8 facing the front is arranged. Adjacent blocks 1 are bonded to each other with an adhesive for concrete, but the front surface 2 or the rear surface 6 faces the front (that is, the character surface faces the front). In the block 1 in which the agent is put and the side surface 8 faces the front, an adhesive is put in the character 3 portion on the front surface 2 and the character 7 portion on the rear surface 6 to adhere to the adjacent block 1. In this way, since the adhesive can be put into the recessed portion, the adhesive cannot be seen from the outside, and the rows of the blocks 1 can be configured with good appearance. Further, an adhesive is applied to the lower surface 10 of each block 1 and adhered to the block rod 13 below. In FIG. 3, the leftmost block 1 and the left gate pole 14 are also bonded by putting an adhesive into the character 3 portion of the front surface 2 of the leftmost block 1.

  FIG. 4 shows an example in which the blocks 1 are arranged side by side on a concrete floor surface of a parking space to form a character string “NAGATA” and used as a car stopper. Each block 1 is an adhesive for concrete, and adjacent ones are bonded together, and a lower surface 10 is bonded to a concrete floor surface. Each block 1 has a character 3 recessed on the front surface 2 and a character 7 recessed on the rear surface 6. For example, the block 1 labeled 1a in FIG. , “A” is recessed in the rear surface 6. Thus, if only one character 7 is recessed not only on the front surface 2 but also on the rear surface 6, by selecting the block 1 having an appropriate combination of characters, the front side and back side of the row of blocks 1 A character string can be created for each. Further, since the character 7 on the rear surface 6 can also be used for the character string, the number of character strings that can be formed by the same plurality of blocks 1 is increased, which is convenient.

  As described above, according to the block 1, a character string can be easily formed by combining a plurality of blocks and used for an exterior or interior. Further, since the block 1 is made of concrete and can be produced at low cost, it is possible to form a character string at a lower cost than when a construction worker or the like is asked to engrave the character string directly on the block.

  Further, since the block 1 has a substantially cubic shape, the width does not change even if the side surface 8 is front instead of the front surface 2 being front. For this reason, the side surface 8 can be used to form a portion without characters, which is convenient.

  Next, a block with letters 20 (hereinafter abbreviated as “block 20”), which is a second embodiment of the present invention, will be described with reference to the drawings. The same reference numerals as in FIG.

  As shown in FIGS. 5 and 6, the block 20 is provided with a hole 21 having a diameter of about 50 mm so as to pass through the center of the block 20 in the vertical direction. The upper end of the hole 21 opens at the center of the upper surface 9, and the lower end of the hole 21 opens at the center of the lower surface 10. The block 20 has the same configuration as the block 1 except that the hole 21 is provided.

  When the block 20 is manufactured, a columnar portion or a cylindrical portion for forming the hole 21 is erected on the lower wall portion of the above-described formwork, but the block 20 is manufactured in the same manner as the block 1 except for this point. To do.

  Next, a usage example of the block 20 will be described. FIG. 7 shows an example in which a block 20 is used at the edge of the flower bed. Here, the three blocks 20 and the four blocks 1 form a character string “WELCOM”, and on both sides thereof, a block 1 with the side surface 8 facing the front is arranged. The blocks 1 and 20 are placed on the soil, and the adjacent blocks 1 and 20 are bonded to each other with an adhesive for concrete. And soil is put in the hole 21 of each block 20, and the plant 22 is planted. In addition, when using it, without laminating | stacking as an edge of a flower bed like FIG. 7, the blocks 1 and 20 do not need to adhere | attach. Without bonding, the blocks 1 and 20 can be easily rearranged and replaced.

  Thus, if a plant is planted in the hole 21 using the block 20 at the edge of the flower bed, a flower bed rich in design can be made in combination with the plant planted in the flower bed itself. The block 20 itself can also be used as a mini flower bed.

  FIG. 8 shows an example in which the block 20 is used alone for hydroculture. A plant cultivation pot 25 is placed in the block 20, a hydroball 24 is placed in the pot 25, and a plant 23 is planted. is there. Although not shown, a tray for receiving water is laid under the block 20. Since the block 20 is made of concrete and has excellent heat retention properties, it is suitable for cultivation of plants that are vulnerable to low temperatures, and is suitable for hydroculture.

  Further, the block 20 can of course be used for the block cage, such as being arranged on the block cage as in the case of the block 1 in FIG. When the block 20 is used as a block rod, the strength of the portion of the block 20 can be increased by inserting a reinforcing bar inserted through the block rod into the hole 21 of the block 20.

  As described above, the block 20 can be used for exterior and interior by forming a character string easily and inexpensively.

  Each of the blocks 1 and 20 has a substantially cubic shape with a side of about 80 mm. However, the size is not limited to this, and may be a substantially cubic shape with a side of about 100 mm. However, the length of one side is preferably about 70 mm to 300 mm from the viewpoint of easy identification and handling of characters.

  Next, a block 30 with characters (hereinafter abbreviated as “block 30”) according to a third embodiment of the present invention is shown in FIG. The block 30 is configured in the same manner as the block 1 except that it has a substantially rectangular parallelepiped shape. In block 30, the same components as those in block 1 are denoted by the same reference numerals as those in block 1, and the description thereof is omitted. Also with such a block 30, a character string can be easily and inexpensively formed and used for exteriors and interiors. Note that the block 30 may have a configuration in which the holes 21 are provided in the same manner as the block 20. The front surface 2 preferably has a side length of about 70 mm to 300 mm from the viewpoint of easy identification and handling of characters. For example, the block 30 may have a plate shape in which the front surface 2 and the rear surface 6 have a substantially square shape with one side of about 300 mm, and the thickness (that is, the length of the upper side and the lower side of the side surface 4 and the side surface 8) is about 50 mm.

  Further, in the block 30 of FIG. 9, the character 3 is a hiragana character. Thus, the character 3 and the character 7 are not limited to English characters, and may be hiragana, katakana, numbers, or the like. Moreover, it is good also as a form which adds a color to the character 3 or the character 7 by apply | coating a coating material.

  In the blocks 1, 20, and 30, characters may be provided only on the front surface 2, or characters may be provided on the front surface 2, the rear surface 6, and the side surface 8. If characters are provided on the side surface 8, different character strings can be formed by making the side surface 8 the front surface. In addition, a character may be provided on the side surface 4 without providing the recess 5. This is because an adhesive may be put in the character portion instead of the concave portion 5.

  Further, although only one hole 21 is provided through the center of the block 20, a plurality of holes 21 may be provided in the case of a horizontally long substantially rectangular parallelepiped shape like the block 30.

  Further, when the concave portion 5 appears on the front surface or the rear surface, or when the concave portion 5 appears on the end surface as shown in FIG. 4, a decorative plate or display property is obtained by fitting and bonding a plate such as an acrylic plate to the concave portion 5. It is also possible to have

  That is, the present invention can take various configurations without departing from the scope of the utility model registration request.
