Description

Porous concrete gravel assembly and its manufacturing method {PORORUS CONCRETE COBBLE AGGREGATE AND THE METHOD}

The present invention relates to a Porous Concrete Cobble Aggregate, and in detail, a volleyball ball-shaped gemstone having a water permeability, namely a multi-functional jadeite, which has already been used in various ways in Japan, namely porous concrete gravel (hereinafter referred to as PCC). The present invention relates to a PCC aggregate formed by forming a plurality of sheets, and integrally molded into a single row or a plurality of rows of aggregates, and a manufacturing method thereof.

Recently, PCC has been used in various ways to improve the environment of rivers. The PCC is a water-permeable molded body formed by forming a gap in the coarse aggregate, fixed with an adhesive paste made of mortar, and finished in a spherical shape. In recent PCCs, not only are they imparted water permeability, but they are also multifunctionalized by mixing artificial zeolites with a hard-hardening mortar-based adhesive paste, making the shape appropriate, or studying the combination method. It is used for a purpose.

As an example of the conventional PCC, there exists an example of what was disclosed by Unexamined-Japanese-Patent No. 10-8435 (porous block and its structure), for example. This is to provide a three-dimensional (XYZ) through hole in a ball of permeable concrete of volleyball ball shape, insert a long bolt into each through hole of each PCC arranged in a column shape, and fasten both ends with nuts. In other words, depending on the situation, it is possible to combine and distribute in one-dimensional, two-dimensional or three-dimensional shape.

As described above, in the case of plural arrangements of the conventional PCCs, long bolts are inserted into through holes formed in the arrangement direction, and both ends thereof are fastened with nuts to fix them.

However, this type of conventional PCC arrangement uses a long bolt to insert and fasten a plurality of PCCs arranged in a column shape to through-holes formed by each PCC. There is a problem in that a lot of cost and effort are required in that the position of each PCC must be accurately determined for the bolt insertion, and the long bolt must be designed to be inserted.

In this regard, long bolts require anti-rust plating, and the bolt cost is quite expensive. In addition, in order to be able to insert the long bolt, the insertion hole formed in the XYZ direction does not necessarily pass through the central axis of the molded body, but is eccentric, and in order to match the eccentric position of each PCC in the same situation, one accurate arrangement work is required. . In addition, in the work of narrow rivers, there was a problem that bolt insertion did not work as intended.

Accordingly, an object of the present invention is to provide a PCC assembly which can be easily arranged by a user without requiring a long bolt, and can be easily handled even in a narrow stream in order to arrange a plurality of PCCs in a river. Another object of the present invention is to provide a method for producing a PCC aggregate, which is easy to manufacture and can significantly reduce manufacturing costs.

This invention for solving the said subject comprised the PCC aggregate and its manufacturing method as follows.

That is, the PCC aggregate of the present invention is an aggregate composed of a plurality of unit PCCs arranged in a single row or a plurality of rows, and when the aggregates are arranged on the ground, the PCC aggregates are bent between the respective PCCs by the weight of each PCC. The bottom surface of each PCC is in close contact with the ground, characterized in that formed by integrally connecting the adjacent PCC to each other by a flexible connecting material.

The arrangement of the PCC at this time is generally in a lattice shape, but only one column may be arranged or may be arranged in a zigzag shape.

The above connection by the flexible connecting material is conditional that neighboring PCCs are connected to each other, and each PCC may be continuously connected using a short connecting material connecting a pair of PCCs. In addition, one long rope may be inserted into a PCC arranged in a thermal form, or a PCC arranged in a grid may be combined with a rope connected in a mesh.

And as a raw material of the said flexible connection material, when an aggregate is arrange | positioned on the ground, it is conditiond that it will be bent by self weight and each PCC will be in close contact with the ground. Specifically, for example, when the weight of one PCC having a diameter of 30 cm is 15 kg, the steel bar may be bent at a torque of 2.25 kg · m, and thus, a thin iron rod or a needle, wire, or thin wire having a diameter of 5 mm or less corresponds to this. However, when steel is used, antirust treatment by plating or the like is necessary. As a more suitable flexible connecting material, a corrosion resistant high strength resin rope such as cremona, aramid or ethylene can be used. These ropes can be woven in a mesh, for example, by placing portions of the meshes between the PCCs, and the projections by the meshes as the fixing portions, whereby the PCCs can be firmly fixed to each other. In order to fix the rope in the PCC by providing a fixing effect, a rope knot may be formed to form a protrusion, or a dedicated metal ball may be fixed on the rope.

Therefore, the PCC aggregate of the present invention has a form in which aggregates arranged in a thermal, lattice, or zigzag form are connected to each other, and can be used as it is by factory production, conveying to rivers, and hanging by cranes and unloading into rivers. In other words, it is possible to eliminate all arrangements, combinations, and insertion of long bolts in rivers. By arranging a number of rows of aggregates, batching can be done quickly.

Combining and combining the aggregates with each other can be performed by, for example, combining the hook members provided in, for example, four corners of the aggregate with each other. In the case of fixing to the earthen bank, it is possible to cope with the anchor bolt to the bolt insertion hole formed in the vertical direction of the PCC. When the shape is matched with the coast of the river, the connection material of the part may be cut in order to remove the PCC of the unnecessary part. In this case, when the connecting material is a thin wire made of metal, the wire may be cut with a thin wire cutter, and it may be cut with a resin rope face knife or heat cut.

The present invention is a PCC assembly formed by connecting the neighboring PCC to each other with a flexible connecting material, molded integrally, the method of manufacturing the same is as follows. When the PCC is spherical, the position of the joint surface to which the upper and lower molds are joined is set to a position slightly lower than the center height of the spherical shape. At this height position, a flexible connector that joins each PCC together is placed. Thereafter, a coarse aggregate coated with an adhesive paste is introduced into the mold, and after curing of the adhesive paste, the lower mold is first removed, and the PCC is supported by the upper mold while the lower mold is removed. The PCC assembly is moved onto a work bench, and then the upper mold is divided and removed in a plane, so that the PCC assembly is placed on the work bench.

In this manufacturing method, even if the PCC is spherical, each PCC can be supported by hanging the upper frame in the state where the lower frame is removed, and the assembly can be placed on the working platform by removing the upper frame after moving the upper frame. You can also stack them.

In general, it is possible to operate a plurality of molds simultaneously. The present invention means that simultaneous molding of a plurality of PCCs is possible in a state in which a flexible connecting member is disposed at the height position of the upper and lower molds as in the simultaneous operation of the plurality of molds. That is, in the present invention, the molding can be produced at the same or higher speed than that of the conventional single production.

In addition, in the present invention, the aggregates can be stacked, and the moving and stacking can be performed in aggregate units. Therefore, by improving these handleability, the total manufacturing cost can be reduced by 30% with respect to the conventional assembly manufacturing cost.

In addition, the manufacturing method in the case where PCC has an extended part with respect to the up-and-down one direction is as follows. When the PCC has an extended portion with respect to the vertical direction, the upper and lower molds are joined with the extended portion as an upper side, and a flexible connecting member is disposed. Thereafter, the coarse aggregate coated with the adhesive paste is introduced from the upper part of the upper mold, and after curing of the adhesive paste, the lower mold is removed at the height of the upper and lower molds, and each PCC is removed from the upper mold. The PCC assembly is supported on the work table, and then the upper mold is divided and removed in a plane. This is characterized in that the PCC assembly is placed on the worktable with the extension part placed on top. For example, when a PCC has an extended part with respect to an up-down direction like the case where a cross section is a ladder type, when an extended part is made to the upper side, when a lower mold is removed, the PCC can be suspended by the upper mold. The mass production can be performed in the same manner as the spherical PCC described above. The same applies to the effects and effects, and the manufacturing cost can be reduced by 30% compared to the production of a single product. Hereinafter, a preferred embodiment will be described with reference to the accompanying drawings.

As shown in Fig. 1 showing an embodiment of the present invention, the PCC aggregate 1 is formed by arranging the volleyball ball-shaped PCC monolith 2 in five arrays. In the horizontal cross section of each PCC 2, the net 3 as an example of the flexible connection material which assembled the aramid rope by the mesh structure is incorporated. In other words, four meshes 4 of the net 3 are embedded in each PCC 2. The height position of the net 3 is located slightly below the center height position of each PCC 2 because of manufacturing reasons that the height position of the net 3 is shifted from the center.

In the planar arrangement of the net 3, two ropes are covered for one PCC in order to avoid the position because the PCCs may be joined together and the joint point is intentionally broken. In this way, avoiding the junction point with respect to the rope passing position, there is an advantage that the PCC can be easily bent, the rope can be easily cut depending on the situation.

About the PCC 2 of the four corners of the said PCC assembly 1, the loop 5 is formed in the outer end of the net 3, This loop 5 is used as a hook at the time of conveyance, and is planar It is for joining together the aggregate | assembly 1 arrange | positioned.

As shown in FIG. 2, when the PCC assembly 1 configured as in FIG. 1 is placed on a curved surface, the PCC assembly 1 is bent between the respective PCCs 2 so that the bottom surface of each PCC 2 adheres to the ground GL. do. That is, the PCC assembly 1 shown in FIG. 1 can be arrange | positioned in close contact with the bottom (ground surface) or inclined surface of a river.

As the flexible connecting member, in addition to the net 3 shown in the drawing, a rust preventive metal wire may be used. In addition, a plurality of knots 4 may be provided in one rope, and a plurality of knots 4 may be arranged in the longitudinal and transverse directions to form a net shape. In addition, since the flexible connecting material is conditional on the coupling of the PCCs, it is also possible to provide a short connecting material between the PCCs 2 that can only be bonded to adjacent PCCs. It is also possible to combine small nets combining a plurality of PCCs, and to combine the whole nets.

Regarding the knot 4, since the object is to fix in the PCC, a relatively small metal fitting may be fixed on the rope.

3 is a front side view of the mold model for manufacturing the PCC assembly 1. The mold of this example is applied when the PCC 2 is spherical. Fig. 4 is a front side view showing a state in which the PCC aggregates 1A and 1B made of this mold are stacked.

In FIG. 3, the mold of this example consists of the lower mold | type 6 and the upper mold | type 7, and the fitting eye of the upper and lower molds 6 and 7 is slightly deviated downward from the center height position.

In the manufacturing procedure, first, the coarse aggregate coated with the adhesive paste is put into the hemispherical part of the lower mold 6, and the upper mold 7 is aligned. Subsequently, the net 3 is placed and the upper mold is aligned, for example, a coarse aggregate coated with an adhesive paste coating is introduced from a hole (not shown) provided in the upper part of the upper mold, and the pressure is kept in a pressurized state to wait for the curing of paste. . Paste curing time is 10-20 minutes because it is formulated as a special rapid curing agent. The method of injecting coarse aggregate into the mold is not limited to this.

After curing of the paste, the lower mold 6 is first removed, and relative to the worktable 8 shown in FIG. 4, the entire bottom surface of the assembly 1 is aligned with the top surface of the worktable 8 such as a pallet. Remove the upper frame (7). Since the upper mold 7 has a divided structure, by dividing the divided body, the assembly 1A can be placed on the work table 8. When the following assembly 1B is manufactured in the same order, this assembly 1B can be put directly on the assembly 1A manufactured earlier, and can be stacked in multiple stages. Since each net 3 extends to each PCC 2 of each assembly 1A, 1B, the load does not fall off.

FIG. 5 is a front side view of the molds 9 and 10 applied to the case where the PCC unitary body is a ladder type as in the case shown in FIG. 3.

In this example, when manufacturing a ladder-shaped PCC (not shown), the coarse aggregate coated with the adhesive paste is added in the same order as shown in Fig. 3, the net 3 is hit, the coarse aggregate is added to the upper mold, and pressurized. Waiting for the hardening of the paste in the state, after which the lower mold 9 is removed, moved to the workbench 8, and then the upper mold 10 is divided and detached, and the PCC assembly is placed on the worktable 8. As shown above, in the manufacturing method of the PCC assembly of the present invention, the PCC assembly 1A, 1B, ... can be made in order in order of taking a plurality, and the work table 8 can be made. You can stack them on top of each other. In this connection, when a plurality of PCCs are conventionally placed on the worktable 8 in the order of taking a plurality of pieces, the stacking method must be pyramid-shaped, so that a large amount of stacking is impossible, and it is necessary to stack them again by human hands. There was. In this example, the labor is not necessary at all, and the manufacturing cost can be considerably reduced as compared with the prior art. In addition, in the conveyance for shipment, the conveyance can be safely performed for each work platform (pallet) 8 by a forklift or the like. For example, a hook can be hooked to the loop 5 shown in FIG. 1 and can be conveyed for every assembly to a crane and other heavy machinery, and conveyance work is very comfortable. FIG. 6 is a perspective view which shows the specific product example of a PCC assembly. The PCC assembly 1C of this example is formed by arranging four rows of PCCs 2 in an annular bench shape of a shape in which the upper part is spherical and the lower part is cut horizontally. Each of the PCCs 2 has the same net as the net 3 shown in Fig. 1, and each PCC is coupled to each other. A hook 11 for conveyance and connection is provided at an intermediate position of each side. When the PCC assembly 1C having the above configuration is installed in a river, a crane car is disposed in the river shore or a crane car in the river under construction. The heavy machine which can hang up heavy goods, such as a backhoe, is arrange | positioned, and the hook 11 is hanged up by a crane hook, and it arrange | positions to a desired position. The hooks 11 of the PCC assemblies adjacent to each other are fixed to each other with a band tool properly rust-treated. In the case where a scab is generated at the riverside, the joint part of the net 3 can be cut and the excess part can be cut out. In addition, PCC aggregates (not shown) manufactured separately, such as 4 bundles 1 row and 4 bundles 2 rows, may be used in combination, for example, to avoid stuttering. FIG. 7 illustrates a PCC aggregate (1C) arranged as shown in FIG. 6. ) Is an explanatory diagram showing a state in which the bottom of the) adheres to the ground GL such as a river bottom. As shown, since the PCC aggregate 1C is a combination of each unit PCC by the net 3 or the like, each PCC is bent in a state in which the bottom face is in close contact with the ground GL. Therefore, it is suitable even when the ground surface GL is curved, and it can respond easily even if the ground surface is an inclined surface. As mentioned above, when installing the PCC assembly of this invention in a river, the primary or secondary ( Compared to the conventional method in which the long bolt is inserted into the through-hole formed in the XY) direction, the effort can be greatly reduced by about 1/2 to 1/3. , PCC assembly (1) installed on the inclined surface becomes a reproductive area of meat and insects under the surface of the water, or a decomposition place of the organic matter in the water and can greatly contribute to water quality improvement. In addition, when installed on the earthen dike, the porous function is maximized to improve the drainage of the surface portion, and also to preserve the high moisture, to promote the growth of microorganisms and small plants, while maintaining the aesthetics of the earthen dike An inclined surface can be reinforced, and the environment improvement of a river surface can be aimed at. The present invention is not limited to the said embodiment, It can implement suitably deformed in the range which does not deviate from the summary of this invention. For example, when installing in a river, although the example of installing a single layer was shown, it can also install by stacking in multiple layers. In addition, there are a wide range of uses, such as landscape construction blocks, water purification blocks, repairing root fixing blocks, greening revetment blocks, artificial reef blocks, and weeding blocks. By incorporating effective materials such as various zeolites, bentonites, iron minerals, color pigments, stone stones, zeolites, volcanic forces, and pumice stones, PCC aggregates suitable for various purposes can be obtained. In the PCC aggregate 1C shown in Fig. 7, the PCCs 2A are joined to each other. In this case, when aggregate 1C is arrange | positioned on the surface GL, it will separate | separate from each other and a fracture surface will mutually arise. Therefore, the said effective material, such as various zeolites and iron ore, can be arrange | positioned intensively in this fracture | rupture surface, and these effective materials can be made to expose by fracture at the surface vicinity.

As described above, the present invention is a porous concrete gravel assembly in which a plurality of porous concrete gravel formed by arranging a plurality of rows or a plurality of rows is bonded to each other with a flexible connecting member, and thus can be installed in aggregate units, and the work is easy, thereby greatly reducing the cost. Can be reduced. In addition, since the bonding by the flexible binder, each porous concrete gravel single body is bent by the weight of the neighboring porous concrete gravel, so that the bottom of each single body can be in close contact with the ground, installation is very easy.

In the case where the above-mentioned flexible binder is formed into a strip or net shape and a projection is formed for fixing to the insertion portion for each porous concrete gravel, the engagement can be secured by the fixing action of the projection.

When the flexible connecting member is made of a high-strength resin rope having corrosion resistance such as cremona or aramid, handling and workability can be easily combined with high quality, and a high-quality porous concrete gravel assembly can be constructed.

In the production of aggregates for spherical porous concrete gravel, the lower mold is formed by using a plurality of mold molds arranged in multiple bundles and placing the fitting point of the upper and lower molds slightly below the center height position. By transporting the porous concrete gravel assembly onto the workbench in a detached state, and then removing the upper frame, the porous concrete gravel assembly can be placed on the workbench and stacked. Therefore, it is easy to manufacture and can mass-produce at low cost.

In the case where the porous concrete gravel has an extended portion with respect to the upper and lower one direction, the porous concrete gravel aggregate is transported onto the work table in a state where the lower mold is removed by carrying the extended portion upward, and then the upper frame is removed to remove the upper frame. Porous concrete gravel assemblies can be placed on top of each other, and can be stacked. Therefore, it is easy to manufacture and can mass-produce at low cost.
