Stone block is separated from the pattern surface.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view showing a state of a housing for manufacturing a stone block according to the present invention, Figure 2 is a state in which the anchor for coupling the pattern forming body and the body in the stone block according to the present invention is coupled to the housing It is a cross-sectional view showing, it will be described with reference.

The stone block according to the present invention comprises a main body 40 (see FIG. 7) and a stone pattern forming body 20 ′ (see FIG. 6) having various patterns while covering the surface of the main body 40. The method of manufacturing the stone block is to separately manufacture the body 40 and the pattern forming body 20 '.

The pattern forming body 20 'according to the present invention is a stone such as cement mortar, and hardens the soil by hardening the soil, as in the manufacture of a general block. To this end, the mold for forming the pattern forming body 20 'has a housing 10 having an uneven surface 12 therein, and a press 30 engaged with the housing 10 to apply pressure to the mortar 20. Reference). At this time, the press 30 is provided with a pattern forming surface 31 for forming a pattern of the pattern forming body 20 '. At this time, the pattern forming body 20 'can be expressed in a variety of colors, as well as precise and sophisticated pattern, for this purpose wet method (filling concrete or cement mortar in the housing, the method of drying in the housing) This can be applied.

As illustrated in FIG. 1, the housing 10 may form a container, and the bottom surface of the container may form an uneven surface 12. Since the uneven surface 12 is for forming a surface to which the pattern forming body 20 'and the main body 40 are coupled, the uneven surface 12 increases the contact area with the main body 40 to increase the bonding force between them.

Subsequently, the anchor 50 is reinforced to the uneven surface 12, that is, the portion where the pattern forming body 20 ′ and the main body 40 are coupled to each other, thereby providing a bonding force between the pattern forming body 20 ′ and the main body 40. Can be reinforced. In this case, in order to arrange the anchor 50 to the rear surface of the pattern forming body 20 ′, the mortar 20 to be injected into the housing 10 may be fixed together with the curing.

To this end, the anchor 50 is fitted into the anchor insertion groove 11 formed in the housing 10 so that one end is positioned in the housing 10. The anchor insertion groove 11 is preferably engaged with the anchor 50 as closely as possible, so that the injected mortar 20 does not leak even when pressure is applied from the press 30.

3 to 5 are cross-sectional views sequentially showing the state of curing by injecting the cement mortar into the housing, it will be described with reference to this.

The mortar 20 in a paste state, which is a material of the pattern forming body 20 ', is injected into the housing 10.

The mortar 20 injected in this way is closely engaged with the housing 10 and inserted into the housing 10, and is subjected to a press 30 applying pressure to the concave-convex surface 12 of the housing 10 and the pattern of the press 30. It is cured in the form of a certain space surrounded by the formation surface (31).

Here, the mortar 20 is mixed with an adhesive such as polyurethane and a reinforcing agent such as a mixture of sodium and carbon dioxide and silicon oxide to secure the insufficient rigidity of the plastering agent 20 'according to the present invention having a relatively thin thickness. To be able. In addition, in addition, rainwater may be introduced into the inside, or a waterproofing agent or an insulation for an insulation lamp, or the like may be added.

These additives are mixed by stirring in the housing 10 before or after the mortar 20 is injected into the housing 10 and cured under a constant pressure applied by the press 30.

In this case, since one end of the anchor 50 is located inside the mortar 20, the anchor 50 is closely fixed together with the curing of the mortar 20, and then, the anchor 50 will be integral with the mortar 20.

On the other hand, as shown in Figure 4, before starting the curing, give a constant vibration to the housing 10 so that the mortar 20 is evenly distributed along the pattern on the rather complicated uneven surface 12. At this time, together with the vibration applied to the housing 10, the press 30 by applying a continuously increasing pressure to the mortar 20, to naturally exhaust various bubbles contained in the mortar 20, mortar ( The gap between the particles of 20) is minimized so that the pattern forming body 20 ′ in the state where the mortar 20 is cured can maintain sufficient strength.

This is because the mortar 20 is not a complete liquid, but because a large number of particles having a predetermined diameter are in a paste state, the fluidity is small and precise adhesion to a fine surface does not occur easily.

When a uniform distribution of the mortar 20 is completed by applying a constant vibration to the housing 10 and the press 30, the applied vibration is stopped and enters a full-scale curing process. The curing process may proceed naturally without applying a separate vibration, and even if the complete curing is not made as shown in Figure 6 by separating the pattern forming body 20 'from the housing 10 and the press 30 It may be cured.

The pattern forming body 20 ′ separated from the housing 10 and the press 30 may be coated with a surface hardener made of an inorganic ceramic and a synthetic polymer to secure surface hardness, and compensate for the strength that may be insufficient. can do.

On the other hand, the mortar 20 is cured and the solid pattern forming body 20 ′ is removed by lifting upward from the housing 10 after removing the press 30. This is to allow the anchor 50 to be easily separated from the housing 10 without interference, and to ensure that the uneven portion 22 formed as it is according to the shape of the uneven surface 12 can maintain its shape without damage. For sake. The pattern surface 21 by the pattern formation surface 31 of the press 30 is formed in the facing surface of the uneven part 22.

The completed pattern forming body 20 'may be utilized as follows.

7 and 8 are cross-sectional views sequentially showing the production of the stone block according to the present invention, will be described with reference to this.

The stone block is to make a raft block or a bottom block that is assembled for embankments and rivers, such as rivers and lakes, the front surface is exposed to the pattern forming body 20 'according to the present invention to express a variety of patterns To be able.

At this time, the front surface of the pattern forming body 20 'as well as the rear surface to be in contact with the main body 40 is also formed, so that the main body 40 by applying the adhesive 60 for bonding with the main body 40 ) And the pattern forming body 20 'to achieve a strong adhesion.

The adhesive 60 may be cement mortar, and the main body 40 and the pattern forming body 20 'may be bonded to each other. On the other hand, since the contact area with the main body 40 is wider than the back surface of the pattern forming body 20 ', it is more efficient to use the cement mortar as an adhesive.

At this time, the main body 40 is made of a standardized block of the same stone has a variety of shapes through the combination with the pattern forming body 20 'having a variety of patterns. At this time, by forming a surface corresponding to the concave-convex portion 22 formed in the pattern forming body 20 ', while the concave-convex portion 22 is closely engaged, the main body 40 and the pattern forming body 20' mutually 7 may be coupled to each other, as shown in FIG. 7, the cement mortar component, which is the adhesive 60, and the concave-convex portion 22 may be in close contact with each other.

On the other hand, the main body 40 is formed with a fitting groove 41 into which the anchor 50 is inserted. The fitting groove 41 is a place where the anchor 50 protruding from the rear of the pattern forming body 20 'is engaged, and the bonding force between the body 40 and the pattern forming body 20' together with the adhesive 60. Can increase.

The stone block body 40 has a predetermined shape, but the pattern forming body 20 ′ may be variously modified, the image of the stone block in appearance can be varied. In addition, since the production of the pattern forming body 20 ′ having various patterns is only required to change the type of the press 30, its utilization is also easy.

On the other hand, in order to naturally reveal the surface color of the pattern forming body 20 ', the surface (part exposed by appearance) of the pattern forming body 20' is inverted, and the pattern forming surface 31 in which pigments of various colors such as colorants are stained. ) Should be covered. That is, the molding is performed in the reverse of the illustrated figure.

In this case, various pigments deposited on the pattern forming surface 31 are absorbed by the surface of the pattern forming body 20 ′ to give a natural color.

However, in order to produce a variety of colors on the surface of the stone block having a vegetation space having a predetermined volume and the front surface, the protruding vegetation space should be turned over and in contact with the pattern forming surface 31, in this case stone Since the load of the block is concentrated in the protruding vegetation space, the vegetation space becomes difficult to maintain its shape. In other words, the stone block having the vegetation space is generally produced by the dry method, there is a limit that can not sufficiently expand the volume of the vegetation space, there is a difficulty in expressing the beautiful appearance through natural colors. In addition, the production of stone blocks through the wet method may be able to enable a sufficient volume of vegetation space and a beautiful appearance of natural color, which has a problem that there is no economic efficiency by increasing the production cost while reducing productivity.

Subsequently, while explaining a stone block according to the present invention and another embodiment of the method for producing the stone block, a solution to the above-mentioned problem is presented.

9 is a side and perspective view showing a state of the pattern forming body coupled to the stone block of another embodiment according to the present invention, Figure 10 is an exploded perspective view showing a state of coupling the pattern forming body shown in Figure 9 to the main body Inva is described with reference to this.

As shown in FIG. 9, the pattern forming body 20 ″ according to the present invention has a container shape so as to secure a planting space in the stone block, and may have various patterns on the front surface thereof.

That is, the housing 10 is molded so as to have the shape of the pattern forming body 20 "as shown in Fig. 9. By the way, looking at the state of the pattern forming body 20" shown (a drawing), The entrance of the upper surface portion 23 of the pattern forming body 20 " is wide, and the closed lower surface portion 24 is relatively narrow, and the outer surface forms a curved surface and forms a beautiful appearance. It can be seen that the stone block is a stone block having a planting space of a sufficient area protruding forward.

However, the stone block having a planting space has a limit in the degree of protrusion of the front surface protruding forward. That is, the conventional method of manufacturing the stone block is a dry method (method of filling the concrete or cement mortar with a housing and molding the shape of the housing and then separating and drying the concrete or cement mortar from the housing), as shown in the figure. The complex and large curvature stone blocks could not be produced.

However, through the method of manufacturing the stone block according to the present invention, by separately manufacturing the pattern forming body 20 "and the main body 40 'which constitutes one stone block, it is only necessary to combine them mutually, the pattern forming The body 20 "is produced through a wet method to produce a variety of complex exterior shapes and beautiful surface colors. The body 40 'is firmly manufactured by a dry method, and then the pattern forming body 20" and the body ( By assembling 40 '), it is possible to overcome the limitations of monotonous and crude stone blocks made only by dry process.

In the present embodiment, as described above, the anchor 50 'and the fitting groove 41' may be applied to mutually assemble the pattern forming body 20 'and the main body 40'. While the pattern forming body 20 "is manufactured, the anchor 50 'protrudes, and while the main body 40' is manufactured, the fitting groove 41 'is formed at a position corresponding to the position of the anchor 50'. It is to let. In addition, if necessary, the adhesive 60 (see FIGS. 7 and 8) and / or the concave-convex portion 22 may be reinforced to increase the bonding force between the pattern forming body 20 ″ and the main body 40 ′. .

11 to 14 is a view showing another embodiment for the appearance of manufacturing a stone block according to the present invention, will be described with reference to this.

As described above, the manufacturing method of the stone block according to the present invention is to manufacture a completed stone block by separately fabricating the pattern forming body 20 "and the main body 40 'and later assembled with each other, After the pattern forming body 20 "is first produced as follows, the body 40" may be manufactured according to the pattern forming body 20 ".

This is explained in more detail.

11 and 12, a pre-fabricated pattern forming body 20 " is inserted into the housing 10 '. At this time, the mold 10' can be injected with cement mortar or concrete in a gel state. As such, the mold 10 'will have to be molded to preserve the shape of the pattern forming body 20 ". That is, as in the embodiment according to the present invention, when the pattern forming body 20 ″ forms a container shape for securing a vegetation space, the cement mortar or concrete is not injected into the space inside the vegetation space. The inner space and the mold 10 'must be closed to each other, while the stone block is a relatively large structure, so that the reinforcing bars 42 must be disposed inside the mold 10' so as to have sufficient durability. Eventually, even if cement mortar or concrete is injected through the inlet 60 of the mold 10 ', the cement mortar or concrete is blocked from entering the inner space of the pattern forming body 20 ", Cement mortar or concrete may be dried while wrapping the reinforcing bar 42 to complete a solid and durable body.

Subsequently, the cement mortar or concrete injected into the mold 10 ′ is uniformly distributed through the vibration of the housing 10 ′, thereby increasing the strength of the main body 40 ″.

The cement mortar or concrete is completely filled in the mold 10 ', and the main body 40 "is separated from the mold 10' and dried according to a dry process. In this case, the main body 40" forms the pattern. Is completely engaged with the sieve 20 ". Meanwhile, in order to increase the bonding force between the pattern forming body 20" and the main body 40 ", as described above, the pattern forming body 20" is anchor 50 '. And anchor 50 'to the reinforcing bar 42 which forms the skeleton of the main body 40 ".

Figure 15 is a perspective view showing the use of the stone block according to the present invention, Figure 16 is a cross-sectional view showing the installation of the stone block according to the present invention, it will be described with reference to this.

As described above, the stone block having a vegetation space formed on the front surface may be applied as a building block such as a retaining wall block, and in order to actually construct it, the following structure may be achieved.

First, the base 91 is laid at the location where the stone block is to be built in the lake or the bottom, and ground 93 is formed to allow water flow and air penetration. The base arm 92 is embedded to resist earth pressure while protecting the ground 93 thus formed.

Subsequently, the stone block is constructed stepwise from the base arm 92 as shown, and then fixed to the base arm 92 via a linker 80 and positioned at the top of the stacked stone blocks. The top surface of the stone block to be finished by placing the Temple of Heaven (94). As a result, the stone block has a sufficient force to resist earth pressure while being firmly fixed to the base arm 92 through a linker 80.

On the other hand, the rear end of the stone block may be provided with a groove 70 is inserted into one end 81 of the linker 80, the other end of the linker 80 is inserted into the base arm 92 is inserted. Grooves (not shown) may be formed. One end 81 and the other end 82 of the linker 80 may be bent to fit perpendicularly to the groove 70 of the stone block and the groove of the base arm 92, respectively.

According to the present invention as described above, even if the main body of the stone by separately producing only the exterior pattern in the entire stone block production, it is possible to economically secure the stone block of the various feelings due to the various patterns, the pattern on the front The back of the pattern forming body is formed is an anchor is formed to increase the bonding force with the main body can be easily obtained after the attachment with the main body without a strong finish effect.
