Description

  The present invention relates to a cement block used for, for example, a building wall, a floor, or a pavement such as a road and a parking lot, and a structure using the cement block.

As building materials such as floors and walls of structures, fences, and road pavement materials, for example, cement blocks formed by curing and solidifying a mixture of cement, sand, water, etc. in a mold are widely used. . Since this cement block is usually formed of a single white or gray color of cement, there is no design and it is easy to give an inorganic texture to the viewer. Therefore, recently, in consideration of landscape, design, etc., for example, a colored block obtained by adding an arbitrary color pigment to a raw material such as cement is often used. On the other hand, for example, Patent Document 1 proposes a technique in which a natural stone having the same size as the block is attached to the surface of the cement block with an adhesive.
Japanese Patent Laid-Open No. 10-18209

  However, since the block colored with the conventional pigment is formed in a single color with the color of the pigment as a whole, the block itself is monotonous. Therefore, the entire surface of a structure such as a wall formed by arranging them is also monotonous, resulting in poor design. In addition, there are cases where blocks colored in various colors are prepared and the structure is constructed by combining the colors. Even in this case, however, the color can be changed only in relatively large blocks, so it is easy to decorate. It was difficult to realize a high pattern. In addition, the color combination design and construction work are complicated, requiring a lot of labor, taking a lot of work time, and increasing the cost.

  On the other hand, in the block in which natural stone is pasted on the surface as in Patent Document 1, the entire surface of a structure such as a wall constructed of the block is monotonous only with natural stone, and thus lacks interest. Furthermore, when manufacturing the block, a process of processing natural stone into the same size as the block and a process of attaching the natural stone to the block surface with an adhesive are required separately from the block molding. It was cumbersome and expensive to manufacture.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a cement block having a decorative pattern rich in decorativeness and interest and a structure using the cement block. . Another object of the present invention is to provide a cement block and a structure using the cement block that can easily manufacture a highly designable block while maintaining the manufacturing cost.

  In order to solve the above problems, the present invention forms a cement molded body 20 by mixing a cement and a decorative inorganic material 22 and forming a mold, and the cement molded body 20 is formed in parallel at a plurality of locations P1 to Pn + 1. Among the blocks provided by cutting, the blocks are made of cement blocks having cutting planes on both opposite faces (121, 122), and the cutting planes are sized so that the cement base surface portion 16 formed by hardening the cement and visible. And a decorative surface 14 including a cut surface portion 18 of a decorative inorganic material having an outer contour line 24. The cement block 10 is characterized in that the decorative surface 14 is formed. The outer contour shape of the decorative surface 14 of the cement block 10 may be arbitrary, and may be any other shape such as a triangle, a rectangle, a parallelogram, a pentagon, a hexagon, a circle, and an ellipse. Further, in response to forming the cement block having the shape, the cement molded body 20 is formed into a three-dimensional shape having the shape as a cross section. In addition, the decorative inorganic material 22 may be used in an arbitrary color. Moreover, the type of the inorganic material 22 for decoration to be mixed may be only one type or a plurality of types. In addition, the size of the decorative inorganic material 22 may be uniform to some extent, or a plurality of sizes may be mixed.

  Further, it may be formed by mixing blast furnace slag fine powder together with cement.

  Moreover, it is good also as the color pigment which colors the color of the cement base surface part 16 mixed with cement, and was formed.

  Further, the decorative inorganic material 22 may be made of a colored inorganic material having a color that is a contrast with the color of the cement base surface portion 16.

  The decorative inorganic material 22 may be made of inorganic waste.

  Furthermore, this invention is comprised from the structures W and F using the cement block comprised by arranging the cement block 10 in any one of Claim 1 thru | or 5 so that the decoration surface 14 may become flush.

  According to the cement block of the present invention, a cement molded body is formed by mixing a cement and a decorative inorganic material, and molding the mold, and the cement molded body is cut in parallel at a plurality of locations. Among them, a cement block having a cutting plane on opposite sides, the cutting plane is a cement base surface portion formed by hardening the cement, and a cutting surface portion of a decorative inorganic material having an external outline that is visible. Therefore, a unique decorative pattern can be formed by the cut surface of the decorative inorganic material, and a highly designable and entertaining block can be realized. Further, the manufacturing can be easily performed and the manufacturing cost can be maintained. Further, since the decorative surface is formed as a flat surface, it is possible to easily finish a structure such as a floor or a wall. In particular, since the decorative surfaces are provided on opposite sides, it is advantageous for constructing a structure having wall surfaces on both sides, such as a bag. In addition, construction work can be easily performed.

  Moreover, since it is the structure formed by mixing blast furnace slag fine powder with cement, the strength of the cement block can be enhanced, and water tightness, chemical resistance, etc. can be improved. Furthermore, it is possible to satisfactorily suppress cracks, cracks and the like caused by a reaction between the alkali component of the cement and the inorganic component.

  Moreover, since it is the structure formed by mixing the color pigment which colors the color of a cement base surface part with cement, the improvement of synergistic design property by the combination of the pattern and color by the cut surface part of a decorative inorganic substance can be anticipated.

  In addition, since the decorative inorganic material is composed of a colored inorganic material having a contrast color with the color of the cement base surface portion, it is possible to obtain a cement block having excellent decorative properties by highlighting the pattern by the cut surface portion of the decorative inorganic material. it can.

  In addition, since the decorative inorganic material is composed of inorganic waste, it can be recycled and used effectively. Furthermore, the material cost can be reduced.

  Furthermore, according to the present invention, since the cement block according to any one of claims 1 to 5 is composed of a structure using a cement block configured so that the decorative surface is flush with the decorative surface, Therefore, it is possible to easily realize a structure having an interesting surface.

  Hereinafter, embodiments of a cement block and a structure using the cement block of the present invention will be described with reference to the accompanying drawings. The cement block of the present invention is a block having excellent decorativeness used for building materials such as building walls and floors, road pavement materials, exterior materials such as fences, and landscape materials such as river revetments.

  1 to 3 show an embodiment of the cement block of the present invention. In the present embodiment, as shown in FIG. 1, the cement block 10 is formed in a three-dimensional rectangular shape, and a set of opposed flat surfaces 121 and 122 is used as a decorative surface 14. For example, as shown in FIG. 4, the decorative surface 14 forms a wall surface when the cement blocks 10 are arranged vertically and horizontally to construct a ridge W or the like. The decorative surface 14 has a cement base surface portion 16 formed by hardening cement, and a cut surface portion 18 of a decorative inorganic material.

  As shown in FIGS. 2 and 3, in the present embodiment, the cement block 10 is formed by cutting and processing a rectangular parallelepiped cement molded body 20 in which cement and a decorative inorganic material 22 are mixed and hardened, for example. . The cutting plane generated by cutting the cement molded body 20 is a flat surface including a cement base surface portion 16 that appears when the cement-hardened portion is cut and a cutting surface portion 18 that appears when the decorative inorganic material is cut. . This cutting plane forms the decorative surface 14 of the cement block 10.

  In this embodiment, the cement used as the hardening material of the cement molded body 20 is made of, for example, gray Portland cement. In the present embodiment, for example, a colored pigment such as a petal is added together with the Portland cement, and the cement-cured portion of the cement molded body 20 is formed in a red color. Accordingly, the cement block 10 is formed by coloring the cement base surface portion 16 in red. The color pigment is not limited to the red petite (iron oxide), and other arbitrary color pigments such as green chromium oxide and blue cobalt oxide may be used alone or in combination. Moreover, you may form the cement base surface part 16 with the gray of cement, without adding a coloring pigment as needed.

  Furthermore, in this embodiment, blast furnace slag fine powder, such as ESMENT (registered trademark), is mixed together with Portland cement. By adding blast furnace slag fine powder to the cement, the long-term strength of the cement block can be enhanced. Furthermore, the water tightness, chemical resistance, etc. of the cement block are improved. Moreover, the crack, crack, etc. which arise when the alkali component of a cement and the component with an inorganic substance react can be suppressed favorably. The mixing ratio of the blast furnace slag fine powder may be adjusted according to the application mode of the cement block. For example, when the cement block is applied to a place where a certain degree of strength is required such as road pavement, the blending amount may be increased. Further, by increasing the mixing ratio of the blast furnace slag fine powder having a high degree of whiteness, the colorability of the cement base surface portion by the color pigment is improved, and it can be colored with a vivid color.

  In the present embodiment, the decorative inorganic material 22 is made of, for example, tiles of a certain size, pumice, porcelain stone, earthenware, pieces of porcelain, charcoal, or the like. As these ornamental inorganic materials 22 such as tiles and pumice stones, for example, inorganic materials discarded in construction, civil engineering work, etc. are preferably used. As a result, the waste can be recycled and used effectively, and at the same time, the material cost can be reduced. In the present embodiment, when the cement molded body 20 is molded, the blending ratio of the powdered material in which cement and blast furnace slag fine powder are combined and the decorative inorganic material is, for example, a ratio of about 1: 3 by weight. Is mixed in. In addition, you may set this mixture ratio arbitrarily. For example, if a large amount of decorative inorganic material such as roof tiles and pumice stones is set, the cut surface portion 18 of the decorative inorganic material tends to appear densely on the cut surface. In addition to what was mentioned above, what is used as the inorganic material 22 for decoration may be other arbitrary inorganic materials such as tile, brick, concrete block, glass, slag, lava stone, shirasu, and inorganic waste.

  As shown in FIG. 2, the decorative inorganic material 22 is cut together with the hardened cement portion when the cement block 10 is formed, and the cut surface portion 18 forms a decorative pattern of the cement block 10. Thereby, a block having a unique pattern and excellent in design can be formed. In the present embodiment, the decorative inorganic material cut surface portion 18 is formed such that a plurality of sizes having a certain size with respect to the cement base surface portion 16 appear. In the present embodiment, for example, the cut surface portion 18 is shown in such a size that the outline 24 can be seen with the naked eye, and the visual effect as a decorative pattern is made effective. Further, in the present embodiment, the decorative inorganic material 22 is a mixture of white ceramic stone, ceramic, pumice or black tile, charcoal, etc., so that the cut surface portion 18 is conspicuous with respect to the red cement base surface portion 16. It has become. That is, the decorative inorganic material is contrasted with the color of the cement base surface portion 16 such as a color having a hue difference, a color having a difference in brightness, a color having a contrast, a color having a difference in strength, and the like. The color is set to enhance the design by making the cut surface pattern stand out. In addition, the combination of the color of the cement base surface portion 16 and the decorative inorganic material is not limited to the above. For example, for the grayish white cement base surface portion 16 formed without adding a pigment, a decorative inorganic material such as brown glazed tile, black pumice, charcoal or the like may be selected. Moreover, it is good also as forming the color of a cement base surface part, and the color of an inorganic material for decoration by the combination of the color of the same system | strain, a color with low contrast, etc. For example, a cut surface portion made of an inorganic material made of brown tile or the like may be formed on a red cement base surface portion.

  As described above, the cut surface portion 18 is formed by randomly changing according to various conditions such as the size, color, shape, mixing ratio, cutting position, etc. of the decorative inorganic material. It should be noted that various auxiliary functions can be added to the cement block by selecting the type of decorative inorganic material. For example, in this embodiment, it is effective as a building material for indoor use or a landscape material as a block considering the environmental aspect and the health aspect by mixing charcoal having an action of adsorbing moisture, deodorization, harmful substances, etc. Applicable. Also, for example, by mixing porous pumice, charcoal, etc., it has water permeability and has a high anti-slip effect due to fine irregularities on the cut surface. For example, flooring materials such as road pavement materials and hot spring facilities It can be applied effectively. In addition, those having a water purification effect or the like can be formed. Moreover, it is good also as mixing the granular material etc. of the inorganic waste finely crushed so that a particle size may be about several millimeters with the inorganic material 22 for a certain size. Synergistic improvements in decoration can be expected due to the large pattern of the cut surface and the small particles interspersed.

  In the present embodiment, the above cement, coloring pigment, blast furnace slag fine powder, and decorative inorganic materials are mixed, put into a mold having a rectangular parallelepiped shape, and cured and cured, for example, a rectangular solid cement. A molded body 20 is formed. As shown in FIG. 2, in the step of cutting the cement molded body 20, the cement molded body 20 is cut in parallel at a plurality of locations P <b> 1 to Pn + 1 (n is a natural number) through, for example, a diamond saw rotary saw or the like. . In the embodiment of FIG. 2, the cuboid shaped cement molded body 20 is cut, for example, at equal intervals on a vertical plane parallel to the left and right end faces, and the three-dimensional rectangular cutting blocks 101 to 10n, 10L, and 10R having the same shape. Is formed. That is, the outer shape of the cement block 10 is determined by the cross-sectional shape of the cement molded body 20 and the length of the cutting interval. Therefore, the cement molded body 20 is formed according to the shape of the cement block 10 to be formed without being limited to the rectangular parallelepiped as in the present embodiment. For example, the cement molded body 20 corresponds to forming a cement block having a decorative surface whose outer contour shape is a triangle, pentagon, hexagon, circle, ellipse, etc. It is formed in a column, cylinder, elliptical column, etc. Moreover, it is possible to easily manufacture from a thin flat block to a thick three-dimensional block simply by changing the cutting position. In the present embodiment, the cutting blocks 101 to 10n having cutting planes on both opposite sides among the cutting blocks formed by cutting are effectively used as the cement block 10. The cement block 10 has a flat decorative surface 14 on both opposing surfaces 121 and 122, which is advantageous when, for example, a structure having wall surfaces on both sides, such as a bag, is formed. Furthermore, it is easy to obtain a flush surface during construction. The other two sets of facing surfaces other than the cutting plane of the cement block 10 are surfaces formed in contact with the surface of the mold. On the other hand, in this embodiment, the side cutting blocks 10L and 10R at the left and right end portions where the cutting plane is formed only on one side are disposed without being used as the cement block 10 (S18 in FIG. 3). . The cut end blocks 10L and 10R may be discarded as they are, or may be crushed to an appropriate size and used as a decorative inorganic material when other cement blocks are formed.

  When manufacturing the cement block 10 according to the present embodiment, as shown in FIG. 3, first, a material containing cement, water, a decorative inorganic material, and the like are blended and mixed (S10), and the mixed material is molded. The cement molded body 20 is formed in a frame. (S12) Then, the cement molded body 20 is cut in parallel at a plurality of locations (S14). Of the cutting blocks provided by cutting, only the blocks whose opposite surfaces are cutting planes are selected as cement blocks 10 (S16, S18).
