Description

POLARUS CONCRETE COBBLE AGGREGATE AND THE METHOD}

The present invention relates to a porous concrete cobble aggregate, in particular, a permeable volleyball-shaped stone that is called a multifunctional jadeite which has already been variously used in Japan, that is, a concrete slab (hereinafter referred to as PCC). The present invention relates to a PCC aggregate formed by integrally molding a plurality of rows or aggregates, and a method of manufacturing the same.

In recent years, the PCC has been used in various ways to improve the environment of rivers, riverbanks, block, earth and sand loss prevention dams, soil retaining walls, fish houses, fish and herbs. PCC is a water-permeable molded body formed by forming a gap in a rough aggregate and fixing it with an adhesive paste made of mortar or the like to form a sphere. In recent PCCs, not only are they permeable, but they are also multifunctionalized by mixing artificial zeolites, adhering shapes, or studying combinations of them on a rigid mortar-based adhesive paste. It is used for.

As an example of the conventional PCC, for example, there is an example of what is shown in Japanese Patent Application Laid-Open No. 10-8435 (a porous block and its structure). This is to install a three-dimensional (XYZ) through hole in a volleyball-shaped water permeable concrete ball, insert a long bolt into each through hole of each PCC arranged in a column shape, and connect the both ends with nuts to fit the situation. It is to be able to combine and arrange in one-dimensional or two-dimensional or three-dimensional shape.

As described above, in the case of plural arrangements of the conventional PCCs, long bolts are inserted into and connected to through holes opened in the arrangement direction, and both ends thereof are fixed with a nut.

However, the conventional method of arranging PCCs requires the preparation of long bolts because a plurality of PCCs arranged in a thermal state are inserted and connected to a long bolt through a through hole drilled in each PCC and connected and fixed by a nut. In order to insert bolts, each PCC needs to be precisely positioned and has to be designed for inserting and connecting long bolts.

For reference, long bolts need anti-rust plating, and the bolt price is quite expensive. In order to be able to insert a long bolt, the insertion hole drilled in the XYZ direction does not necessarily pass through the central axis of the molded body, but one accurate arrangement is required to match the eccentric position of each eccentric PCC. Become. In addition, there is a problem that bolts are not inserted or connected properly in narrow river works.

Herein, in the arrangement of a plurality of PCCs in a river, the present invention basically provides a PCC assembly which does not require long bolts, can be easily disposed without effort, and can easily cope with narrow rivers. The purpose.

In addition, it is an object of the present invention to provide a method for producing a PCC aggregate, which is easy to manufacture and can significantly reduce production costs.

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, this invention comprised the PCC aggregate and its manufacturing method as described in the claim.

That is, the PCC aggregate of the present invention is a PCC aggregate formed by arranging a plurality of PCCs in a unit and arranging the above aggregates on the ground by a PCC aggregate formed of one or multiple rows of aggregates. It is characterized in that the bottom surface is in close contact with the above-mentioned ground between the PCC adjacent to each other by a flexible connection, made by integral molding.

The arrangement of the PCC is generally in the form of a lattice, but it may be arranged in the arrangement of only one column or in a similar cross shape.

Since connection by flexible connection material is a condition of connection between adjacent PCCs, each PCC may be connected continuously using the short connection material which connects one PCC. The PCCs arranged in a thermal state may be joined by ropes joined to a net.

As a raw material of a flexible connecting material, when an aggregate is arrange | positioned on the ground, it is conditiond that it bends by self weight and each PCC adheres to the ground. Specifically, for example, when the weight of one PCC having a diameter of 30 cm is 15 kg, the steel bar or wire, wire, or bare wire having a diameter of 5 mm or less corresponds to this because it can be bent by a torque of 2.25 kg · m. For the use of wrought iron, antirust treatment by plating is required. More suitable flexible connector, Cremona, Aramidotennak, Corrosive high strength resin ropes such as ethylene can be used. The rope can be firmly fixed to each other by, for example, weaving the rope into a net, placing the eye part of the net between the PCCs and anchoring the humps of the eye as an anchor. To anchor the rope in the PCC with an anchoring effect, a rope knot may be made to form a lump or a dedicated bracket may be fixed on the rope.

Therefore, the PCC assembly of the present invention has a columnar or lattice shape, or aggregates arranged in parallel to each other and are connected to each other, which can be used as a factory produced, transported to a river, bundled with a crane, and laid down in a river. In other words, it is possible to omit all the work of arranging, assembling in the river and inserting and connecting long bolts. By arranging various types of hot water aggregates, batching can be performed quickly.

Combination and coupling between the aggregates can be performed by engaging the hook members provided at four corners of the aggregate, for example. Fixing to earth can be done by placing anchor bolts in the bolt insertion holes drilled in the vertical direction of the PCC. In the case of fitting the shape at the end of the stream, the connection material of the part may be cut except the PCC of the unnecessary part. In this case, when the connecting material is a metal wire, the cutting material may be cut with a wire cutter, and the resinous rope surface may be cut with a knife or thermally cut.

In addition, the present invention, by connecting the PCC adjacent to each other with a flexible connecting material, when the PCC is a spherical form of a PCC assembly made of integral molding, the joining surface of the up and down molding frame is set slightly below the height of the spherical center And arranging the flexible connecting member for coupling each PCC to each other at this height position, and putting the coarse aggregate coated with the adhesive paste into the forming mold to harden the above adhesive paste, and then removing the lower forming mold. By supporting the PCC, the above-mentioned PCC assembly is moved to a table, and the above-mentioned forming mold is divided in a plane to be detached, so that the above-described PCC assembly can be placed on the table.

According to the manufacturing method of the present invention, even if the PCC is spherical, each PCC can be supported by being pulled down from the upper mold in a state where the lower mold is removed, and the upper mold is removed by moving the upper mold. You can place an aggregate. Of course, it can be stacked.

In general, it is possible to operate a template of a plurality of simultaneously. The present invention means that a plurality of PCC simultaneous molding can be performed in a state where the flexible connecting member is disposed at the height position of the upper and lower frames as in the simultaneous operation of the plurality of molds. That is, in this invention, it can manufacture at the speed | rate equivalent to or more than the conventional one-piece manufacturing in molding.

In the present invention, it is possible to stack the aggregates, and to move and stack the aggregates. Therefore, by improving the handleability, it is possible to reduce the total manufacturing cost of the conventional aggregate manufacturing cost by 30%.

In addition, the present invention is a method of manufacturing a PCC aggregate formed by connecting the adjacent PCC with each other by a flexible connecting material, when the PCC has an extended portion in one direction up and down, the above expansion portion is coupled upward A flexible connecting material is placed, and the coarse aggregate coated with the adhesive paste is put on the upper mold, and the above mold paste is dried, and then each PCC is removed from each other under the mold at the height position where the upper and lower molds are set to arbitrary heights. The PCC assembly is moved to the table by supporting each PCC with the above mold, and then the above mold is separated in a plane and separated and the above expanded portion is placed upward. It is characterized in that one PCC assembly can be placed.

In the present invention, for example, when the PCC has an extended portion in one of the upper and lower directions, such as in the case of a flat section, the PCC is attached to the upper mold when the lower mold is removed by extending the expanded portion upward. It can support and can be mass-produced in the same state as the above-mentioned spherical PCC. The same applies to the effects and effects, and the manufacturing cost can be reduced by 30% compared to the production of single products.

In Fig. 1 (plan view) showing the practice of the present invention, the PCC assembly 1 is formed by arranging five rows of PCC units 2 in the shape of a volleyball ball. In the horizontal cross section of each PCC 2, the net 3 is incorporated as an example of the flexible connection material which assembled the aramid rope by the net structure. The weave is a form in which four knots 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. The deviation from the center of the height position of the net 3 is for manufacturing reasons.

In the planar arrangement of net 3, two ropes are covered for one PCC in order to avoid the position because some PCCs are joined together and the joints are intentionally broken. Thus avoiding the junction with respect to the rope passing position, there are advantages of being able to easily bend the PCC and to be able to cut the rope easily depending on the situation.

With respect to the PCC 2 at the four corners of the PCC assembly 1 described above, a loop 5 is formed at the outer end of the net 3. This loop 5 is used for joining together the planarly arranged aggregates 1 which are used as a hook at the time of conveyance.

As shown in Fig. 2, the PCC assembly 1 constructed as shown in Fig. 1 is bent between each PCC 2 when placed on a curved surface, and the bottom surface of each PCC 2 is in close contact with the ground GL. . That is, when the PCC aggregate 1 shown in FIG. 1 is disposed on the river bed (ground) or the surface of the river, the PCC aggregate 1 can be bent properly between the PCCs, and the bottom surface of each PCC can be installed in close contact with the river bottom or the surface.

The flexible connecting material may be a metal wire material which is rust-prevented in addition to the net 3 shown in the drawing. In addition, a plurality of knots 4 may be provided in one rope, which may be arranged on the net by vertically and horizontally arranged multiple copies. And since the flexible connector is subject to the coupling of the PCC each other, it is also possible to install a short connecting member between each PCC2 that can be bonded to the adjacent PCC. It is also possible to assemble small nets that combine PCCs several by one and combine them together.

Regarding the knot 4, for the purpose of anchoring in the PCC, a relatively small bracket may be fixed on the rope.

3 is a front side view of the mold model for manufacturing the PCC assembly 1. The template in this column applies 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 the column is formed in the lower mold 6 and the upper mold 7, and the fitting points of the upper and lower molds 6 and 7 are pushed downward from the center height position little by little.

When the manufacturing procedure is shown, first, the coarse aggregate with a close paste is put into the hemispherical part of the lower mold 6, and the upper mold 7 is aligned. Subsequently, the net 3 is obtained, the upper mold is aligned, and, for example, a coarse aggregate coated with an adhesive paste is put in a hole (not shown) provided on the upper mold, and the paste is waited for curing under pressure. Paste hardening time is about 10 to 20 minutes because it is formulated as a special instant economy. Input method into the form of coarse aggregate is not limited to this.

After the hardening of the paste, except for the lower mold 6, the mold 1 is moved relative to the stage 8 shown in Fig. 4 so that the entire bottom surface of the assembly 1 is aligned with the upper surface of the pallet light tower 8. Thus, the upper mold 7 Exclude.

Since the upper mold 7 has a divided structure, the assembly 1A can be placed on the table 8 by dividing the divided body. When the following assembly 1B is manufactured in the same order, this assembly 1B can be put on top of the assembly 1A manufactured earlier, and can be stacked in multiple stages. Since the net 3 is laid on each PCC 2 of each aggregate 1A, 1B, a load does not fall.

FIG. 5 is a front side view of the molds 9 and 10 that are applied to the case where the PCC unit is in a large shape as in the case shown in FIG.

In this example, in manufacturing the PCC (not shown) of the large shape state in the same order as shown in Figure 3, the coarse aggregate with the adhesive paste is put, the net (3) is laid, and the coarse aggregate is also added to the upper mold in the pressurized state After waiting for the hardening of paste, and then move to the base (8) except for the lower mold (9), and then the PCC assembly on the stand (8) can be stacked and stacked except the upper mold (10).

As described above, in the manufacturing method of the PCC aggregate of the present invention, the PCC aggregates 1A, 1B, etc. can be sequentially made in the order of forming molds, and can be sequentially stacked on the base 8. . For reference, when a plurality of PCCs are placed on the table 8 in the order of forming molds in the related art, a large amount of stacking is impossible because the stacking method must be in a pyramid state, and it is cumbersome to rebuild through human hands. There was this. In this example, the manufacturing cost which does not require the effort at all can be considerably reduced compared with the conventional.

In the conveyance such as shipping, the conveyance can be safely carried out for each pallet 8 by the hawk lift, etc., for example, the hook can be hooked to the loop 5 shown in FIG. 1 to convey the assembly to the crane or other heavy machinery. Very comfortable

6 is a perspective view showing a specific product example of the PCC aggregate. The PCC assembly 1C of the present example is formed by arranging four rows of PCCs 4 in a round punch shape of a shape in which a top is spherical and a bottom is cut horizontally. Each PCC is combined with each other. Hook 11 for conveyance and connection is provided in the center position of each side.

In the case of distributing and installing the PCC assembly 1C having the above-described structure in a river, a crane hook can be lifted by placing a heavy truck capable of lifting heavy goods such as a crane car or a forcine in a river under construction, or by placing a crane car near a river. ), And lift it up and place it where you want.

The hooks 11 of the PCC assemblies adjacent to each other are fixed to each other by band brackets which are subjected to red rust prevention. In the middle of the river, it is also possible to cut the extra portion by cutting the joints of the net 3, and separate PCC assemblies (not shown), such as 4 rows, 4 rows, 2 rows, etc. It can be used in combination.

FIG. 7: is explanatory drawing which shows the state which the bottom surface of 1C of PCC aggregates installed as shown in FIG. 6 closely adhered to the surface GL, such as a river bottom. As shown in the figure, since the PCC assembly 1C is a combination of each unit PCC by a net 3 or the like, each PCCSMS bottom surface is bent in a state of being in close contact with the ground GL. Therefore, it is suitable also when the surface GL is a curved surface, and even if it is a normal surface, it can respond easily.

As described above, the installation in the PCC aggregate stream of the present invention is compared with the conventional method of inserting and connecting a long bottle into a through hole drilled in the primary or secondary (XY) direction of each PCC. It is possible to greatly reduce 1/2 to 1/3.

As described above, the PCC aggregate 1, which is divided on the river bed, earth and sand, and the surface of the river, becomes a reproductive area of fish and insects under the surface of the water, or can be a decomposition place of underwater organic matter, which can greatly contribute to water quality improvement. To be installed on earthen soils, the drainage of the surface part is exerted to the fullest, and the high moisture is preserved to promote the growth of microorganisms and small plants to protect the aesthetics of the earthen soil and to reinforce the surface of the river. We can contribute to environmental improvement.

The present invention is not limited to the above embodiment, but can be appropriately modified and implemented within the scope not departing from the gist of the present invention. For example, in the installation of rivers, an example of a single-floor facility is given. It is widely used for various purposes such as landscape construction blocks, water purification blocks, water root fixing blocks, greening revetment blocks, artificial reef blocks, and reef blocks.

In addition, it is possible to obtain a PCC aggregate suitable for various purposes by mixing effective materials such as various zeolites, pentites, iron ores, coloring pigments, feldspars, coal stones, volcanic groups, and pumice in association with adhesive pastes and coarse aggregates.

In the PCC aggregate 1 shown in Figs. 6 and 7, the PCC 2A is joined to each other. In this case, when the aggregate 1C is placed on the ground surface GL, the fracture surfaces are separated from each other. Here, the effective materials such as various zeolites, iron ores, etc. can be concentrated on the fracture surfaces so that the effective materials can be exposed by fracture near the surface.

As described above, the present invention is a porous concrete cable assembly formed by combining a plurality of concrete concrete cables which are arranged in multiple rows or multiple rows with a flexible connecting material, so that the present invention can be installed in aggregate units and the work can be easily reduced to greatly reduce the cost. Can be. In addition, since each of the concrete concrete cables are adjacent to each other and the concrete concrete cables are bent and bent by their own weight, they can be brought into close contact with the ground, and the installation work is very easy.

When the humps are formed for fixing to the insertion and connection parts of each concrete concrete cable with the flexible connector turned off or in the net state, the hump action of the humps can ensure the coupling.

When the flexible connecting material is made of high strength resin with corrosion resistance such as cremona or aramid, it is easy to handle and work, and high quality bonding can be made, and high quality concrete cable aggregates can be formed.

In the structure of the aggregate for concrete spherical concrete cables, the concrete concrete cables are removed in the state of removing the harness by lowering the fitting point of the upper and lower molds slightly from the center height position by using a molding frame made of several arranged in multiple rows. You can move the assembly onto the pallet and remove the Hart, so that you can place the porous concrete aggregate on the pallet. It can also be stacked. Therefore, it is easy to manufacture and can be mass produced at low price.

If the concrete concrete cable has an extended part in one direction up and down, the porous concrete cable assembly can be placed on the pallet by excluding the upper part by moving the porous concrete cable assembly to the pallet without removing the upper part. have. It can also be stacked. Therefore, it is easy to manufacture and can be mass produced at low price.
