Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete for vegetation in which plants propagate on the exposed surface of a concrete block that constructs a river bank, a slope, a road retaining wall, a slope, a retaining wall for a home-building park, etc. The present invention relates to a block and a method for manufacturing the block.

[0002]

2. Description of the Related Art The construction of a river bank, a road retaining wall, a house retaining wall for a house, etc., starting from a disaster, is currently a structure in which a solid white concrete surface is exposed. The exposed surface was a structure that completely destroyed the natural environment without any edges.

[0003]

The entire exposed surface of the conventional retaining wall structure is a concrete-colored exposed surface that has destroyed the natural environment with no edges. To improve this important problem, the applicant has previously made several proposals. Patent application for the present invention, the present invention is further improved,
Provided is a method for producing a small concrete block which is produced by immediate demolding in which the strength of a block is maintained at a specified level and plants are vegetated on the exposed surface of the block.

[0004]

The present invention provides a plant on the exposed surface.
The method of manufacturing concrete blocks of each shape to be vegetated and the concrete is put into a mold of each shape, compacted by vibration pressure, cured with the mold, and a hollow part for vegetation is planted on the exposed surface to be removed from the mold after the concrete hardens. This is a method for manufacturing the large-sized concrete block provided. In particular, there are many variations in the conventional manufacturing method and apparatus for concrete that is manufactured by compacting the backing part that exposes plants that are produced by immediate demolding to the exposed surface. The main cause of this variation is automation in order to eliminate human labor, but the manufacturing equipment, as well as the blocks produced by compaction and poor electrical control, still produce variations that are worse than manual operation. Concrete blocks are manufactured. By improving this adversely affecting operation, we have succeeded in always operating at a constant time according to the control time without lowering the strength of the backing section by the operation of each section that is always stable and without variation.

[0005] The main causes of the irregularity of the block, the manufacturing apparatus, and the malfunction of the electrical control are the changes due to the weight of concrete that is fed into the formwork at the specified time and the formwork such as the hopper structure and the feed box structure. It was discovered that the supply of materials was not constant and the product was uneven, or the electrical control of the manufacturing equipment failed, and the cause of this malfunction was investigated.
Not only small concrete blocks manufactured by immediate demolding that vegetates vegetation on the exposed surface, small concrete blocks that expose natural stone blocks and sand grains on the exposed surface, or small concrete blocks whose exposed surface is rough rough surface Has succeeded as a result of repeated research and trial manufacture on manufacturing with constant time control.

EXAMPLE FIG. 1 shows a molding machine for molding a small concrete block for vegetation plants to be produced by immediate demolding, which is a split molding mold in which a hard mold plate is attached to the inner surface of a mold (2) and is vibration-proof. It is attached to the machine frame so that it can move horizontally via the rubber (1-1). The split mold (2) is a split mold of a small block b shown in the cross section of FIGS.
The vibration isolation rubber (1-1) attached to the machine frame that moves horizontally is loosened and removed by loosening the screws of the vibration isolation rubber (1-1), and the vibration isolation is performed by loosening the next split molding die. Rubber (1
-1) Tighten the screw tightly, and it is not necessary to install and adjust the screw in a short time. Vibrators (5-2) having a necessary vibrating force for the split mold are fixedly provided at appropriate places. This split mold (2) is placed on the molding machine shown in FIG. 1 and the left and right sides are opened and closed in the center with a rough surface. It is attached to 1) and gives effective vibration only to the molding die (2), and cuts off vibration transmission to unnecessary parts. A diaphragm device for placing a surface pallet P and moving up and down is provided below the split mold.

Next, the processing of the surface pallet for forming the exposed surface of the block into a rough rough surface will be described (see FIGS. 2 and 7).
Since the blocks having other shapes are also configured and processed in the same manner, the description thereof will be omitted. The configuration and processing of the circular block of FIG. 2 and the octagonal plane pallet of FIG. 7 will be described. When a tapered hole is formed in the center of the surface pallet P and the tapered core die bottom portion abuts and presses, the ring (27) for inserting the loose rubber plate (28) is fixed, and the ring (27) peripheral bottom surface. A thick layer of a mixed material of natural sand grains S-S and small lumps S is formed in an appropriate place. The upper part of the mixed material is washed out by spraying water from above the mixed natural material with the fountain nozzle W, and the residual water permeates the lower mixed material and is dehydrated through the pores (29) provided at several places. . The mixed roughened sand grains S-S and the washed rough uneven rough surface of the small lumps S and the protruding portions of the small lumps are embedded in the concrete, and the unwashed layer portion is separated between the layers to be concrete exposed.

The treated surface pallet P is placed on the vertically moving diaphragm (5), and is raised to the bottom of the integrally formed split mold (2) and temporarily stopped. Or, it rises up to a predetermined position and activates a vibrator provided at a proper position in the split mold (not shown because the mounting position with a different block shape is also changed), and at the same time separated from the material supply box (18). The front plate (22) is
5) to form an integrated supply box (18), and the front plate (2)
While activating the vibrator (24) fixed to 2), it moves forward to the position A to feed the front part of the concrete contained through the formwork opening, and when the set constant time comes, the feed box ( 18) is a core taper tube (10) forming a taper hole waiting at the upper side when it advances to the position, and penetrates the inside of the material box (18) depending on the mixing state of concrete to feed the form (2). Promote materials. Do not perform when the kneading state is constant. The front box vibrator of the material supply box also stopped and returned to its original position. Instead, the taper-shaped core cylinder (10) and the vibration damping rubber (18) were installed above the core cylinder. The core cylinder (10) is press-fitted into the concrete in the mold together with the press plate (11) that moves up and down by the compression of rubber, and the lower surface of the core cylinder is inserted into the center ring (28) of the surface pallet P. At the same time as compressing the elastic rubber (27), the press plate (11) also compresses the anti-vibration rubber from A to B shown in the figure to press and finish the concrete upper surface, and when this affirmation ends, the tapered core cylinder (10) is hung The anti-vibration rubber (1
3) By the compressive force from B to A, the press plate (11) is pressing the concrete surface, the tapered core cylinder moves slightly upward, and the tapered core cylinder is pulled out from the concrete and demolded. , The tapered core tube is restored to its original position together with the press plate. Of course, when the lower part of the tapered core cylinder reaches the ring of the surface pallet, the vibration of the form plate vibrator (5-2) and the diaphragm (5) mounted on the surface pallet P are also stopped. Next, the split concrete mold (2) that horizontally moves and opens and closes is attached. The concrete that is molded by the split mold with the opening of the machine frame that horizontally moves to the left and right leaves the surface pallet, and the others are immediately removed from the mold. Immediately removed from the block with the surface pallet by moving the vibration plate on the pallet down. When the block is transferred to the curing transfer compare (9) waiting at the bottom, the next processed surface pallet is transferred to the vibration plate. A concrete block, which is placed (not shown) and which repeats this process to vegetate on the exposed surface, is molded and manufactured by immediate demolding.

The construction of the second hopper (15) and the material supply box (1
The structure of 8) will be described. A belt compare device (17) for supplying a second hopper (15) for storing 3-4 pieces from the bottom of a first hopper (not shown) for storing one kneaded portion by a mixer; Explaining the structure of the two hoppers (15), the concrete which is accommodated in such a manner that the lower part of the front face is inclined so that it opens outward is inevitably supplied concrete.
8), the drop supply is surely performed, the light emitting hole (16-1) of the photoelectric tube (16) is formed above the hopper, and the concrete mountain C is dropped into the material supply box (18) by being accommodated in the second hopper. The material is compacted by its own weight due to the function of the photoelectric tube in an imbalance that contains concrete mixed with a mixer in the formwork,
When the compare provided with the bottom of the first hopper (not shown) of concrete is operated and the required amount is supplied to the second hopper, the concrete mountain C is formed, the irradiation of the photoelectric tube is cut off, and the compare is stopped. By repeating this operation, the concrete molds of various shapes shown in Fig. 1 are supplied with concrete in order to surely supply them to the integrally formed molds of the split molding molds from the set time. The molding machine shown in FIG. 1 operates smoothly and the efficiency is improved.

Next, the structure of the supply box (18) will be described.
The front plate (22) is inclined downward to the outside, and the front plate (22) separated from the feed box is formed into an integrated feed box (18) via a vibration-proof rubber (25). , The vibrator (24) fixed to the front plate (22) at the time of material feeding to the form is started, temporarily stopped at the position A, and further moved to the position B to feed the form (2) to the form box. The concrete stored in is supplied to the formwork, and the vibration of the front plate is also stopped when the feed box is restored to its original position. The time at which the material supply box is temporarily stopped at A and moved forward to the B position and stopped is freely adjusted with one knob. By repeating this process, the material supply box with the structure of automatic material supply box does not need to be supplied accurately and accurately to the formwork, because there is no variation in the concrete block and it operates reliably at the set time. , The concrete block of each shape exerts outstanding power to mold the concrete block quickly and accurately.

Next, the water for vegetation vegetation is backfilled on the surface of the small concrete for immediate demolding shown in FIG. 1, and the water permeable from the soil is infiltrated into the vegetative soil mixed with the culture soil fixed to the surface. Toward the bottom surface pallet that penetrates from the exposed surface to the buttocks, a core molding cylinder (10) that is slightly thinner than the buttocks of a block is used as a cylinder that moves up and down the core cylinder equipped with a press plate that can move up and down. It is hung and attached to the fixing plate which is fixed via a vibration proof rubber (13). If the block shape of the tapered core cylinder equipped with this press plate is different, a tapered core cylinder having a shape adapted to the block shape is used. In the above, detailed description is given of the configuration in which the tapered hole that allows water from the backfill soil to permeate and permeate is formed on the exposed surface of the small concrete block that is molded by immediate demolding for vegetation. This is used for the block molding of concrete small-sized blocks which are molded by immediate demolding for plant vegetation as described above.

Next, with reference to FIG. 11 and subsequent drawings, a construction for forming and manufacturing a large-sized concrete block in which concrete having a high fluidity is supplied to a form and compacted by vibration to grow plants on the exposed surface will be described. The formwork device to be molded is the formwork shown in FIGS. 11 and 12, and is a formwork that opens and closes on the basis of a rotating device at the bottom of the four directions, and the bottom plate provided at the bottom of the formwork device that opens and closes is placed. When placed, the open four-way form is closed and placed in a defined position of a formwork unit that is integrally composed.

Next, the core tube (35) forming a tapered hole penetrating from the exposed surface to the buttocks of the block is circular in the figure, but depending on the shape of the large concrete block, for example, an elliptical shape, a square shape, a rectangular shape. Other, a core cylinder adapted to the block may be used, but it is better not to use a core cylinder having a shape that adversely affects the block strength. The taper core tube (35) is fixed to the bottom plate by fixing the number corresponding to the exposed surface of the block with bolts (36) from the bottom surface of the bottom plate, and does not move to vibration compaction of concrete poured into the formwork. (See FIG. 12). The bottom plate (33) is provided with water draining pores (41) at several places around which a taper core tube is fixed and placed on the bottom plate placing table (40), and the molds that are open in four directions are closed to form an integral body. To compose.

A bottom plate (33) to which a tapered core tube (35) is fixedly mounted is installed in the bottom of the frame to close the four-direction open frame, and a natural material is formed between the core tubes formed into an integral frame. Of the sand grains S-S and the stone block S of a size adapted to the exposed surface of the natural material,
A natural material mixed with the sand grains is formed in an even amount as much as possible to form a layer, and water is sprayed from above to wash out the upper layer of the mixed material. It is dehydrated through the water draining pores (41) provided in the.
This completes the preparation of the tapered core cylinder (35) which penetrates the natural sand particle aggregate surface and the natural stone size stone surface on the exposed surface to the buttocks where the exposed surface is small.

Next, concrete is poured into the prepared formwork, and vibration is applied from the bottom to the formwork and the supplied concrete to cause air bubbles contained in the concrete to escape upward during compaction. Is short of the amount that it is compacted. Replenish it while giving vibration from the bottom. Further, although not shown, if the block shapes are different, vibration is applied from the side surface of the proper position of the mold where the composition is made to compact and air bubbles are evacuated, and the shortage of the upper concrete is supplemented during vibration. When the compaction is completed, the mold is heat-cured, and the mold (34) composed after the concrete is hardened is opened in four directions to release the mold. The large concrete block shown in the front view of FIG. 13 and the side view of the partial cross section of FIG. Are molded and manufactured. The shape of large concrete blocks is particularly different,
Therefore, since the exposed surface is different, it may be necessary to form the concrete upper surface as the exposed surface. in this case,
The reduced side of the tapered core cylinder shown in FIG. 12 is opened and closed in four directions so that the exposed surface is on the upper side. Pour the concrete that was poured into it into a compacted form by vibrating it first, and then spray the mixed material of the sand granules described above around the core tube in a layered manner as much as possible in order to form a natural stone mass that is larger than the mixed material. Place it in a spotted pattern at an appropriate position, part of the mixed material layer supplied to the concrete top surface with a slight vibration and part of the natural stone block placed in a patchy part are embedded in concrete for heat curing, and the mold is set by concrete hardening. Remove from the frame. When the demolded concrete stands upright, the mixed material that is not embedded in the concrete falls naturally, and the exposed surface of the concrete block shows a rough rough surface around the tapered hole. It is clarified that this structure is completely different from the conventional structure in which a stone block is artificially embedded in concrete.

Next, the small aggregate to be molded by immediate demolding is filled with a taper hole that penetrates to the buttocks with a small exposed surface, and the coarse aggregate that is always used and the tapered hole that penetrates from the exposed surface of the large concrete to the buttocks are used. The structure for filling the coarse aggregate which is always used by those skilled in the art for filling is similar. Therefore,
This construction will be described in more detail. A resin net-like lid (26) is firmly inserted into the exposed surface, the coarse aggregate is filled into the tapered hole to a predetermined position, and the net-like resin lid (26) is solidified. After inserting it, it is assembled at a construction site by engaging and engaging to build it at an arbitrary height.

Next, the present application omits the labor and labor conventionally used by those skilled in the art, and completely eliminates the labor and labor, and the natural sand grains on the exposed surface and the natural stone lump of a size adapted to the exposed surface. The mixed natural material is mixed around the taper hole where the exposed surface is formed, and a mixed natural material with a layered thickness is supplied to sprinkle water from above, and the upper layer of the mixed material is washed out. After dehydration from the water-removing pores provided in, the mixed natural material in the lower layer is compacted, the concrete is cured and cured, and the washed-out portion is embedded in concrete, and the lower layer is separated by surface pallet peeling. However, the interlayer separation surface becomes the exposed surface.

By this method of molding a small concrete block and a large concrete block to be molded by instant demolding, a tailored small and large shaped tailoring used for constructing a river bank with a gentle slope with the exposed surface reduced in place. Form a taper that penetrates to the surface, fill the taper hole to the specified position with coarse aggregate after stacking, and apply clay culture soil to a suitable thickness on it,
Vegetation is completed by planting plant seedlings or spraying seeds for germination. In the figure, reference numeral (3) is a form opening / closing cylinder, (7) is a block b lifting cylinder, and (8)
Is a pushing cylinder, and (21) is a feeding box operating cylinder.

[0021]

As described above in detail, the mold for vegetating plants on the exposed surface by immediate mold removal is a double-structure split mold in a short time in an actuator frame that moves horizontally through a vibration-proof rubber. Just replace it and no adjustment is required. Small concrete blocks, and large concrete blocks, and large and small upholstered blocks with gentle slopes.
Adapted to large-scale concrete surface and surface that reaches the bottom of the block from the soil filled with supplemental water that is indispensable for vegetation on the surface of the block Coarse aggregate that is always used by ready-mixed concrete operators is filled in the tapered hole of the shape, and the exposed surface around the opening formed on the exposed surface is uneven with sand grains used by the ready-mixed concrete operator mixed with small natural materials. Clay for vegetating plants on rough surfaces, clay mixed with plant seeds for cultivation soil Clay culture soil is applied to the entire surface of the rough rough surface with a taper-opened surface to the thickness required for vegetation, or seeds are not mixed Clay culture soil is applied, and the coarse aggregate filled in the tapered holes from the backfill soil for planting plant seedlings is permeated with water to replenish the clay culture applied on the entire exposed surface to replant the plants. The small and large sized vegetation vegetation constructed in this way, and the upholstered concrete block are exposed to only water by penetrating the tapered coarse aggregate formed even in the soil water pressure of the backfill soil during heavy rain. The retaining wall constructed to replenish the clay culture soil mixed layer on the projecting surface retains the condition at the time of laying. The blocks that have been fitted and meshed with each other disperse soil water pressure to replenish the exposed surface, so that only the water is reliably replenished to the exposed surface from the lower part to the upper part of the constructed retaining wall. The block itself receives the seismic force dispersed by the vibration force due to the earthquake, and the mutual blocks are further engaged and strengthened. The straight holes of each shape are water-conducting holes that give water from the backfill soil to the plants vegetated on the exposed surface, and once the heavy soil has penetrated into the backfill soil, the backfill soil will be in a soil water pressure state. Backfilled soil and water flow out through the straight hole that guides the soil water pressure into each shape, and the soil filling the back of the constructed retaining wall is gone, so it is expensive to prevent collapse due to disaster. There is a great risk that the body will become a structure with secondary disasters. In order to prevent the outflow of this backfill soil to the exposed surface, the method of filling the backfill soil with a block buttocks is also the test result.The wire mesh due to the backfill soil water pressure is clogged and the soil water pressure is not yet relieved. The applicant also has the test results. In addition, even if water is hydrated by using porous pumice stone as a decorative material or porous volcanic lava stone that is considerably expensive on the exposed surface of vegetation, the water hydrated by the porous material is dried. It has the drawback that it does not play its part and that plants are not grown. In addition, as for the mixed material obtained by kneading small sand particles, which is the natural material of the present application, a person skilled in the art now forms a sand layer on the surface pallet as a cosmetic material for the exposed surface and arranges natural stone or lava stone on the sand layer. However, the present application is not necessary at all, and the trouble and trouble of first arranging the decorative materials side by side and forming a sand layer between them are omitted. The natural stone cosmetic material which is expensive is not used, but it is always mixed with the aggregate used by ready-mixed concrete contractor and concrete block contractor and sand with small lumps, and water is sprayed from above to mix the upper layers. This is a means for washing out the material, allowing the residual water to permeate the lower layer of the middle layer to compact it, and dehydrate it through the drainage pores formed on the bottom surface of the pallet. At present, there are many techniques in which any means used by those skilled in the art can be omitted.
