DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the method for producing a patterned concrete molded product according to the present invention will be described below with reference to the drawings.

FIGS. 1, 2 and 3 show a patterned concrete molded article 1 manufactured according to the present invention, in this case a pavement block. FIGS. 1 and 2 show a traffic sign pattern, and FIG. 3 shows a pattern pattern. Is expressed.

The block shown in FIG. 1 comprises a pattern layer 2 and a base layer 3 having the same thickness, and the pattern layer 2 is exposed on a part of the surface of the block. In this block, as described later, a pattern material is filled in a part of the stand spacing of the standing pieces that stand densely and stand in the forest as arranged in the formwork, and the base material is filled with the base material in the remaining part of the stand spacing of the stand pieces. It was manufactured by filling the same thickness as the material. On the other hand, also in the block of FIG. 2, the pattern layer 2 is exposed on a part of the front surface of the block, but the back surface of the block is formed only by the base layer 3. That is, the thickness of the base layer 3 is small at the portion lining the pattern layer 2 and thick at the portion exposed on the surface. This figure 2
As described later, a part of the stand interval of the standing pieces that stand densely and stand in the forest three-dimensionally arranged in the formwork is filled with a pattern material, and the remaining part of the stand interval of the stand pieces is included in the block. This was manufactured by filling the entire remaining portion not containing the pattern material with the base layer material.

In the block shown in FIG. 3, the pattern layer 2 forms the entire front surface, the back layer is formed with the base layer 3, and the base layer is not exposed on the surface of the block. This block is filled with the pattern material to fill the entire stand spacing of the densely erected standing pieces of the forest solids arranged in the formwork as described later, and the remaining portion of the formwork inside the formwork that does not contain the above-mentioned pattern material It was manufactured by filling the entire substrate material. Note that the order of filling the pattern material and the base layer material is arbitrary in manufacturing any block.

The present invention relates to a concrete molding having the pattern layer 2 exposed on a part or all of the surface as illustrated in FIGS. A forest solid 5 is used in which the standing pieces are densely erected from the surface and stand (FIG. 4), and the pattern layer 2 is a dry concrete pattern material.
The base layer 3 is formed of a concrete base layer material.

The support member 5a of the forest solid 5 is a support member such as a metal plate, plastic, rubber, wood, paper, woven fabric, or non-woven fabric, and the sheet includes a net material such as a net or a mesh. In addition, for the sake of convenience, the standing piece 5b standing from the surface shows a thin projection like a pin for convenience in the drawing, but other than that, a small standing piece, a pipe, a fiber raised by flocking, raising, bristles, or a knitted or woven fabric is used. A formed pile, a loop such as a loop may be used, and it is desirable that thin standing pieces stand densely and densely from the surface of the supporting material, and the height is at least equal to or greater than the thickness of the pattern layer to be formed. Make it higher.

The dry concrete pattern material is mainly composed of cement powder, resin, or a mixture thereof, a pigment, or a mixture of these and fine aggregates. The material for the pattern layer that can be easily loosened and supplied, and the concrete base layer material is mainly composed of cement powder, resin, and fine aggregate. It contains different pigments and / or coarse aggregates and various fibers as necessary.Even if it contains water even from absolutely dry, it is not kneaded with water and easily loosened. It can be a dry material for the base layer composition that can be supplied by feeding, or a hydrated material for the base layer composition made by kneading with water, so-called ready-mixed concrete. Crushed stone and crushed There slag, or a mixture of fine other materials that reflect light, condensation curing accelerators, waterproofing agents, admixing the swelling agent other admixtures. The above-mentioned various fibers are metal fibers, carbon fibers, synthetic fibers, glass fibers and the like.

In order to produce a molded article by the production method according to the first aspect, the standing piece 5b made of a water-insoluble material such as metal, plastic, rubber, wood, paper, non-woven fabric, knitted fabric, fiber, etc.
Is used, but when the molded body is molded and solidified, the standing material is left in the molded body to remove the support material, or
In order to remove the standing piece from the molded body and remove the entire Hayashi solid,
If the uprights are to be left in the molded body, use a material or structure that allows the uprights to be easily separated from the support, make the support water-soluble, or dissolve the adhesive when the uprights are bonded to the support and fixed. It is good to make it easy to dissolve in water, for example,
In the case where the standing piece is removed from the molded body to recover the three-dimensional forest, it is preferable that the standing piece is tapered to facilitate removal. Furthermore, when the forest solid after filling is inverted and arranged in the formwork, or when a forest solid of mesh sheet material is used, the forest solid may be removed before solidification. In addition, when removing the standing body from the molding material to remove the forest body, the forest body can be removed cleanly by vibrating one or both of the mold and the forest body with a vibrator or ultrasonic waves, and the standing piece comes off. It can help each material fill the trace.

In order to manufacture the block shown in FIG.
As shown in FIG. 5, a forest solid 5 on which standing pieces having the same height as the depth of the form are standing is arranged in the mold 4, and a pattern circle is formed among the forest standing intervals of the many standing pieces of the forest solid. A red dry pattern material 2R inside a part of a forest stand that expresses a ring and a straight line that crosses the inside of the ring at an angle, and two approximately half circles inside the ring separated by a diagonal straight line Is filled with the same thickness as the blue dry pattern material 2B, the dried base material 3D, or the hydrated base material 3W outside the circular ring inside some of the forest stand intervals. The filling order is arbitrary.) When the filled base layer material is dry, the required water: cement ratio is adjusted to the base material 3D and the total amount of the cement and resin of the pattern materials 2R and 2B. When water is supplied to the entire interior of the mold, and the water is used, Moisture contained in the layer material 3W, patterning composition 2R, and 2B and the base layer material 3D or 3W to produce a molded article solidified integrally demolded from the mold 4 Once hardened.

In order to manufacture the block shown in FIG. 2, as shown in FIG. 6, a pattern material 2R, 2 which is thinner and dried than the block thickness is applied to a part of the stand interval of the standing pieces of the stand in the form.
B is filled in the same manner as in FIG. 5, and then the remaining stand spacing and the dried base material 3D or the hydrated base material 3W on the pattern materials 2R and 2B are filled into blocks of a required thickness. When the base material is dried, water is supplied to the entire inside of the mold, and when the base material is added with water, all the materials are solidified with the moisture contained in the base material, and then the mold is removed. As shown in the figure, the entire inside of the mold is thinly filled with the dried base material 3D or the hydrated base material 3W, and a water-soluble forest solid 5 is placed thereon as a supporting material. Design materials 2R and 2B to a part of the stand height of one piece,
The remaining stand spacing was similarly filled with the base material 3D or 3W so as to form a block of a required thickness. When the base material was dry, a required amount of water was supplied to the entire inside of the formwork and water was added. When the base material is used, all the materials are solidified with the moisture contained in the base material and the mold is removed, or the entire inside of the mold is filled with a dry base material or a hydrated base material. After filling the dry pattern material in a part of the stand interval of the three-dimensional standing pieces and the base material in the remaining stand intervals, press another plate or sheet from above to hold the pattern material and the base material, and then invert. Then, while removing the board or sheet on the base material previously filled into the formwork, the pattern material, the base material, and the Hayashi solid are placed, and as it is or the Hayashi solid is removed, and the base material is removed. If it is dry, place it all over the inside of the formwork. And the amount water, demolded and allowed to set integrally all the material in water containing the it when hydrolyzed with base layer material. In this case, it is good to use the surrounding frame together with the holding plate or sheet when inverting, and make the surrounding frame thin, or if it is made water-soluble, put it inside the mold and remove it It is not necessary. Further, when the holding plate or sheet is water-soluble, it is not necessary to remove the holding plate or sheet. In this case, the forest solid may be removed before solidification as described above.

In order to manufacture the block shown in FIG.
As shown in the figure, of the stand intervals of the standing pieces of the three-dimensional forest in the formwork, a white dry pattern material 2W is applied to the portion representing the snow at the top of the mountain, and a brown dry pattern material 2Br is applied to the portion representing the mountain skin. , A blue dry pattern material 2 for the sea
B, the portion representing the sky is filled with a dry sky blue pattern material 2S thinner than the thickness of each block, and then the base material 3D or 3D which is dried so as to form a block of a required thickness over the entire interior of the formwork. Filling the hydrated base layer material 3W,
Contrary to the above, first the base material 3D
Or 3W, and then dry the pattern material 2W, 2Br, 2B, 2S to a part of the stand interval of the stand pieces of the stand.
Is similarly filled. Then, when the filled base material is dry, a required amount of water is supplied to the entire inside of the mold, and when the base material 3W is added with water, all the materials are solidified with the moisture contained in the base material and the mold is released. .

Although the size of the three-dimensional forest is adjusted to the inner shape of the form in the drawing, it may be slightly larger than the outer shape of the pattern to be expressed, and it is not always necessary to match the inner shape of the form. In the case where a step is formed on the surface of the molded body due to the thickness of the Hayashi solid support material, which is inconvenient, the support material may be made water-soluble. or,
The filling of each pattern material at the stand intervals can be performed manually or by a robot, but for accurate and quick filling, the opening is the same size as the forest solid and has an opening corresponding to the pattern. It is advisable to use a closed mask except for the part.

Since the pattern of the molded body in FIGS. 1 and 2 is composed of a red pattern and a blue pattern, as shown in FIG. 4, a mask MR having an opening R corresponding to the red pattern and a blue pattern are formed. A mask MB having a corresponding opening B is used. Both masks have the same outer shape as the forest solid 5, and when accurately placed on the forest solid 5, the respective openings R and B can express the respective patterns of red and blue.

Therefore, one of the masks, for example, MR, is first superimposed on the three-dimensional forest, and the red pattern material 2R is filled through the opening R at a required interval, then the mask MR is removed, and the mask MB is removed. The mask MB may be removed by overlapping the blue pattern material 2B through the opening B to fill the other required forest stand intervals.

In the case where the base material 3D to be filled is a dry base material 3D, the cement contained in the base material and each pattern material,
An appropriate amount of water is supplied to the entire interior of the formwork so that the required water: cement ratio is achieved with respect to the total amount of resin. However, if necessary to adjust the movement of each material, supply a part of the water first if necessary. May be. In the case where the base material 3W is filled with water, each pattern material is mainly humidified by the moisture contained in the base material 3W.
The water in the water: cement ratio is increased. Of course, when it is insufficient to humidify the pattern material only with the moisture of the base layer material 3W, additional water may be supplied.

The height of the standing piece of the forest solid 5 may be equal to the thickness of the layer for filling the pattern material. However, as shown in the figure, the height is lower than the height of the formwork 4 and higher than the thickness of the pattern material layer. Good to do.

When the molded article is released from the mold, the upright piece is left in the molded article to remove the support material of the forest solid as described above, or the upright piece is removed from the molded article to remove the forest solid. .
When the upright pieces are left in the molded body, the finish of the pattern layer becomes beautiful by coloring the upright pieces in advance with a color that matches the color of the pattern material. In addition, if the upright pieces protrude from the surface of the molded body and remain, they may be cut, but if the upright pieces are made of low melting point plastic or fiber, lightly apply heat to the surface of the molded body, and the Shrink and solidify the protruding part to remove it neatly. Furthermore, when the support material of Hayashi 3D is water-soluble and is lost, or when the adhesive for fixing the standing pieces to the support material is water-soluble and the support material is peeled off from the molded body, traces of the support material may be lost. , It is only necessary to remove traces of the adhesive. In the case of using a mold form in which the bottom plate and the surrounding frame can be separated, the forest solid 5 is arranged on the bottom plate, and after filling the pattern material 9 and the base material 10 as shown in FIGS. 5, 6, and 8, respectively. Applying a holding plate or sheet to the upper surface of the mold, invert the entire mold, remove the bottom plate and remove the three-dimensional forest, and then solidify in the surrounding frame, or moisture contained in the base material, or the base material And the moisture supplied to one or both of the pattern materials may be solidified in the surrounding frame and removed from the mold. Further, after filling each of the pattern materials into the forest three-dimensional space 5 outside the formwork at the stand intervals, a holding body of a plate or a sheet is applied to the upper surface, and the board or sheet is turned over by an appropriate holding method. Place the pattern material as above, remove the holder and the forest solid if necessary, and fill and harden the base material,
It may be solidified, or it may be solidified with the moisture contained in the base layer material, or the water supplied to one or both of the base layer material and the pattern material, and then removed from the mold. Fill the base material in advance, put the inverted forest solid and each pattern material on top, remove the forest solid, and then solidify it, or fix the moisture contained in the base material, or one of the base material and the pattern material Or solidify with water supplied to both. In this case, it is preferable to use a thin peripheral frame to invert it. If the peripheral frame is insoluble in water, it is removed, and if it is water-soluble, it is not necessary to remove it.

In order to produce a molded article by the production method of the second aspect, a forest solid having standing pieces made of a water-soluble fiber or other water-soluble material is used. And, unlike the manufacturing method of the first aspect, the upright pieces of the three-dimensional forest are dissolved in the mold, so that no upright pieces remain in the molded body, and no trace of the removal is left.

1, 2 and 3 according to the second aspect of the present invention.
In the embodiment of the production of the molded article of the present invention, the step of removing the standing piece of the forest solid and the step of separating the support material of the forest solid from the standing piece are not necessary, and the implementation of the above-mentioned claim 1 is not necessary. This is the same as in the example, and the traces of the standing pieces that have dissolved and disappeared are filled with the pattern materials surrounding them and the pattern material and the base layer material collapsed. Vibration or pressure may be applied to promote collapse.

When it is desired to dissolve the standing pieces as soon as possible, for example, after filling all the dried pattern materials, water may be supplied to humidify the pattern materials first, and then the base material may be filled. . In this case, the amount of water to be supplied to the dried base material 3D after that is reduced, and the water content of the added base material 3W is set to be small. Furthermore, if the hydrated base layer material 3W is filled before the pattern material, the standing pieces may be dissolved before the pattern material is filled. Therefore, the material is water-soluble but requires a long time for dissolution. Make a piece. In addition, if the support material of Hayashi 3D is made water-soluble as well as the standing piece, the trouble of peeling the support material from the molded body can be omitted.

Since the stand pieces of the three-dimensional forest are dissolved and disappear in the mold, the height of the stand pieces only needs to be equal to the filling thickness of the pattern material. There is no need to match.

In any of the above-described manufacturing methods of claims 1 and 2, a finer pattern can be expressed by arranging thin standing pieces at a high density. In addition, when the formwork is placed on a table vibrator and vibrated when filling the pattern material and the base layer material with the vibrator or ultrasonic wave, the density of each material increases. , Can be densely filled. Further, it is preferable to press with a press when all the materials are solidified, since the materials are densely filled in the forest intervals of the standing pieces of the forest three-dimensionally.

Similarly, in either of the first and second manufacturing methods, whether the forest solid body 5 having the compressible bulky support material is arranged on the inner surface of the bottom of the formwork 4 or not. As shown in the figure, a bulky mat 6, for example, a non-woven fabric is laid, and a forest solid having a water-soluble or flexible support material is placed thereon, and the dry pattern materials 2R and 2B to be filled are formed. ,
One or both of the base layer materials 3D and 3W to be filled, or part or all of them, in this case, the pattern materials 2R and 2B
When the swelling agent is mixed with the material, the material mixed with the swelling agent until it is hardened expands by compressing the bulky support material of the forest structure and the mat 6 as shown in the figure. Therefore, the surface of the pattern layer or the base layer is raised from the surface of the molded body to make the pattern three-dimensional. Also, in the figure, the upper surface of the mold is open, but when the upper surface is closed with a heavy lid, the material expands only toward the bulky support material or the mat 6, so that a more three-dimensional appearance is obtained. A pattern can be formed. Further, when a material having water absorbency is used for the mat 6, excess water is absorbed, and water is uniformly distributed to each material, so that the performance of the molded body can be improved in strength.

FIG. 9 corresponds to the embodiment of FIG. 5, but the same applies to the embodiments of FIGS. In FIG. 7, since the pattern material is filled on the filled base layer material 3D or 3W, for example, an expanding agent is mixed into the pattern material, and the pattern layer is raised on the surface of the molded body without using a bulky mat. be able to. In this case, if a water-absorbing mat is laid on the inner surface of the bottom of the mold, the performance of the molded body can be improved in strength as described above.

Further, according to the manufacturing method of any one of claims 1 and 2, a part or the whole of the mold 4 is made of a deformable material, and after filling each pattern material and the base material 3D or 3W. The mold can be deformed, and each material can be solidified inside the deformed mold to produce a molded body other than the block shape. This is hereinafter referred to as a pattern layer similar to that shown in FIG. The case where a molded article having No. 2 on the surface is manufactured will be described.

FIGS. 10 to 12 show an embodiment in which a cylindrical molded body is manufactured. The mold 10 is made of a deformable peripheral frame 11 made of urethane rubber or the like, and a metal for mounting the peripheral frame 11 thereon. It is composed of a rollable bottom sheet 12 such as a thin plate, a plastic sheet, paper, a nonwoven fabric, a woven or woven fabric, and a rubber sheet.
A forest solid whose supporting material can be deformed is arranged at a predetermined position in the interior surrounded by 1 or a forest solid having a deformable supporting material is used for the bottom sheet 12 if possible, as in the case of FIG. The dried pattern materials 2R and 2B and the dried base material 3D or the hydrated base material 3W are filled (FIG. 10). When both materials are solidified, the bottom sheet 1 is placed on the surrounding frame 11.
2 (see FIG. 1).
1) The inner material surrounded by the surrounding frame 11 is supported between the bottom sheet 12 and the auxiliary sheet 13 and is rounded together with the surrounding frame 11 (FIG. 12). Thus, a molded body having the pattern layer 2 exposed at a required position on the peripheral surface can be manufactured.

FIG. 13 shows a mold 14 which fills the pattern material and the base layer material and solidifies as shown in FIG. (Cylindrical), and kept in that state until both materials solidify to produce a cylindrical molded body. In this case, both materials 2R, 2B and 3D exposed on the open upper surface of the peripheral frame 11
Alternatively, since the surface of the 3W is in contact with the outer surface of the mold 14, the auxiliary sheet 13 can be omitted, and a cylinder forming body having a polygonal cross section can be manufactured by using a polygonal mold.

When the two side edges of the peripheral frame 11 are adjacent to each other when they are rounded or wound according to the manufacturing method shown in FIGS. 12 and 13, a space seam is formed between the side edges of the base material. Are overlapped a little inside and outside, and the base material is doubled inside and outside at the seam, or each side edge of the peripheral frame 11 is cut off, and the base material exposed at each side edge is abutted, and a space is formed at the joint. Not to occur.

Similarly, after the pattern material and the base material are filled in the mold 10 as shown in FIG. 10 and solidified, the peripheral frame 11 is removed as shown in FIG. And wrapping it together with the bottom sheet 12 on the outside of a mold 15 having flanges 15 ', 15' at both ends, and keeping the state until both materials are hardened (see FIG. 15) to produce a cylindrical molded body. Can also. Of course, the width of the inner shape of the peripheral frame 11 is shown in FIG.
As in the case of 3, the mold 15 is placed so as to correspond to the length of one circumference of the outer periphery of the mold 15, and the vertical length is made to match the interval between the flanges 15 ', 15'. Also in this case, the auxiliary sheet 13 can be omitted and the mold 15
Can be used to produce a cylinder-shaped body having a polygonal cross-section other than a cylinder.

Although the above is a method for producing a cylinder-formed body, a molded article other than a cylinder can also be produced by partially or entirely deforming a mold.

For example, after filling a pattern material and a base layer material into a mold frame 10 as shown in FIG. 10, the lower mold having a concave portion 16 on the upper surface and a gel 17 filled in the concave portion as shown in FIG. 18 and pressed from above with an upper mold 20 having a convex portion 19 corresponding to the concave portion 16 (FIG. 17). As a result, the upper surface is pressed by the convex portion 19 and dented, and the lower surface is pressed into the concave portion 16. A downwardly swelling molded body can be manufactured.
In this case, it is not necessary that the peripheral frame 11 be deformable because the part deformed by the mold is a part of the bottom sheet 12. Further, the gel 17 filled in the concave portion is for keeping the portion of the bottom sheet located on the concave portion 16 flat until it is pressurized by the upper die 20, and when the pressing of the upper die 20 starts. The bottom sheet pushed into the recess and the material thereon spills around from the upper edge of the recess. The lower die 18 may be made of a plastic material such as clay. In this case, the upper surface of the lower die made of a plastic material is depressed by pressing the upper die, so that the concave portion 16 is formed, and the gel 17 is formed therein. Filling can be omitted.

Furthermore, after filling the pattern material and the base layer material into the mold frame 10 as shown in FIG. 10, the mold frame 10 is placed on a lower mold 21 having an uneven upper surface as shown in FIG. (FIG. 19), thereby deforming the mold 10 and the two materials filled therein assuming the upper and lower surfaces of the lower mold 21 as irregularities, thereby producing a tile-shaped, eight-bridge-shaped or the like molded body. You can also. The mold 10 in this case may be constituted by the deformable peripheral frame 11 described above and a bottom sheet 12 laid under the bottom thereof, but the bottom surface of the deformable peripheral frame is formed by a deformable bottom wall. It may have a closed bottom.

The present invention is applicable not only to the above-mentioned blocks, cylindrical or polygonal tube-shaped bodies and plate-shaped bodies, but also to buildings constructed by casting fresh concrete on site, for example, buildings of buildings. The present invention can be applied to the molding of a certain ceiling slab to produce a ceiling slab having a pattern layer exposed on the upper surface or lower surface.

In addition, in the inside of the mold to be molded, in addition to the various fibers and fibers such as the above-mentioned metals and fibers, a reinforcing bar,
By incorporating a reinforcing material such as a lath net, expanded metal, various types of ropes and wires, it is possible to manufacture a strong molded body. Further, when the reinforcing material is laid on the previously filled base layer material (or pattern material) and the pattern material (or base material) is filled thereon, the filled upper and lower materials can be prevented from shifting. At the same time, the bond between the pattern layer and the base layer can be reinforced at the interface.

[0041]

According to the present invention, it is possible to easily manufacture a concrete molded body which expresses a pattern by exposing the pattern layer to a part or the entire surface of the molded body in a Kintaro candy style.
And even if the surface of the molded body is worn, the expressed pattern does not disappear or become unsightly.

Further, since the pattern layer is formed of a dry pattern material filled in the stand intervals of the stand pieces of the three-dimensional stand in the mold, the pattern layer can be filled without gaps and the standing pieces left in the molded body can be filled. By coloring in advance as necessary, a clear pattern can be expressed in harmony with the color of the pattern layer.In addition, traces of removed and traces of standing pieces that have dissolved and disappeared will cause the pattern material and base layer material to collapse. Since it is filled, the boundary between the pattern layer and the base layer can be expressed finely, and a molded article having a very clear pattern can be obtained.

Further, since the pattern material is dry, if it is erroneously filled at the stand interval, it can be easily removed by using a vacuum cleaner-type tool and removed by suction.
