It is a front view of another conventional mat and a concrete rectangular block.

Here, a concrete block assembly mat in which a large number of concrete blocks suitable for the present invention are assembled into a single mat, in particular, a demolding device for a mat with concrete pseudo-stone concrete, and an embodiment of the demolding method This will be described with reference to the drawings.
The concrete pseudo-stone block 1 (hereinafter simply referred to as “block”) used in the present embodiment is as shown in the perspective view of FIG. 1, and one block is vertical (X) 30 cm, horizontal (Y) 30 cm, and high. (Z) The size of about 10 cm, four large pseudo stones 12 and two small pseudo stones 13 are arranged on the substrate 11, and the surface of the pseudo stone has an unevenness imitating natural stones. The bottom surface 14 is substantially flat, and the plurality of concrete pseudo stone blocks of this embodiment themselves have complex irregularities on the periphery and top surface, and there are no straight portions on the outer periphery and joint line of the block pseudo stone, and the top surface is flat. Because it is a natural stone pattern, it was made of a shape that was suitable for walking on the waterside by workers and completed workers.
Of course, the present invention is not limited to the pseudo stone block but also to a mat with a concrete block in which rectangular concrete blocks 1a as shown in FIG. 16 are assembled.

As shown in FIG. 2, a mat 2 with a concrete pseudo-stone block used in this embodiment (or a mat 2 in which concrete rectangular blocks 1a as shown in FIG. 16 are assembled is included. The bottom surface 14 (see FIG. 7, the top surface in the formwork) in contact with the concrete block is a non-woven fabric of polypropylene fiber that is resistant to alkali chemical reaction such as cement material. For reinforcement, a rope 21 in which a bundle of polypropylene or polyester filaments is twisted is incorporated.
This mat 2 has an overall average thickness of 3 mm or more, and the entire concrete pseudo stone block 1 per mat in this embodiment is 1.3 tons. Therefore, when the mat 2 is lifted during construction, Must have the strength to withstand, the tensile strength in the machine direction is 2.94Kgf / 5cm, the tensile elongation is 15% or less, and the permeability is 1 × 10 ^-2 cm / sec. used.
As shown in FIG. 2, in this embodiment, the mat 2 is made of the above-described concrete pseudo stone block 1 with an adhesive which will be described later in 20 to 30 rows in the vertical direction (X direction) and 6 columns in the horizontal direction (Y direction). The mat gripping portions A, B, and C that are fixed and have a mat that does not have the block 1 at the end portion A (left side in FIG. 1), the end portion B (right side), and the end portion C (bottom side) of the edge. (Upper side) is provided with a mat joint D that allows the concrete pseudo-stone block 1 to slightly protrude from the mat 2 (see FIG. 2).

In construction, as shown in FIGS. 14 and 15, in construction such as revetment, the mats 2 with the plurality of concrete pseudo-stone blocks 1 are collectively used by a forklift 6 as shown in FIG. After being loaded on a transport vehicle and transported to the site, first, the gripping parts A and B without the block of the mat 2 are gripped by the gripping tool 7 provided on the forklift 6 with a forklift 6 or the like, and then on the revetment at the construction site. The mat 2 is directly laid, and both grips A and B of the mat 2 are fixed to the bank side E and the river side F. Further, when the next mat is laid down, the pseudo stone block 1 of the joint portion D having no grip portion is placed on the grip portion C of the left end portion of the mat 2 that has already been installed. Lay down closely. The forklift 6 or the like grips and moves both grips A and B of the mat 2, but at this time, the mat 2 is greatly curved and then returned to a flat state. The resin mortar 4 layer easily has fine and narrow cracks, but these cracks impart water permeability and air permeability, and it is not necessary to provide a through hole with a punch or the like. Further, if the cracks are small and insufficient, the desired number (amount) of cracks can be obtained by alternately repeating the curved state and the flat state.
After that, it is sufficient to leave the next mat 2 directly as it is, and the joint portion D of the two mats 2 is hidden behind the pseudo stone block 1 and cannot be seen from the outside, and the entire revetment is uniformly covered with the pseudo stone block 1. It has an appearance, and the non-woven mat 2 has a basis weight with a space through which plant roots can enter, so that not only water passes but also plant roots enter between the pseudo stones. In combination with the accumulation of the soil, plants grow and a revetment that matches the natural environment as a whole is formed. Of course, the size of the mat 2 and the shape and size of the gripping portions A, B, C are appropriately changed according to the situation of the construction site.

[Block mat formwork]
Next, a method for manufacturing a mat with a pseudo stone block made of concrete used in this embodiment will be described with reference to FIGS.
As shown in the plan view of the mold shown in FIG. 3, the mold 3 for the above-described pseudo-stone block has individual suspicious stone molds 32 corresponding to the number of the plurality of pseudo-stone blocks 1 mounted on the mat 2 with the concrete pseudo-stone block. And a plurality of suspicious stone molds 32 are integrated into one large (question stone) mold 3.
In this rectangular mold 3, the outer frame 31 around is made of FRP resin, the pseudo stone mold 32 forming the inner pseudo stone is made of polyurethane resin, and the bottom of the mold 321 (see FIG. 10) has reinforcing bars and iron plates. Is embedded to reinforce the entire formwork.
As shown in FIGS. 4 and 5 showing the skeleton with the mold 3 removed, the overall shape of the mold 3 is provided with a solid base frame 33 of a steel frame on the outer periphery of the outer frame 31, and both longitudinal directions of the outer frame 31. In this embodiment, a metal (iron) frame protection receiving plate 34 is provided near each of the left and right side surfaces in the present embodiment, and this frame protection receiving plate 34 corresponds to a block receiving portion 53 of the demolding device 5 described later. It is located at the position to be.

On the bottom surface 38 (see FIG. 5), a reinforcing steel frame 35 is hung between the pair of longitudinal outer frames 31, and the bottom surface 38 of the concrete mold 3 below the frame protection support plate 34 is orthogonal to the longitudinal direction. The H-steel guided member 36 is stretched from side to side to serve as a reinforcement.
In addition, square fork insertion members 37a and 37b into which the forks 61a and 61b of the forklift 6 are inserted are provided at substantially the center inside the outer frame 31 in the longitudinal direction. The fork insertion members 37a and 37b are hollow with a rectangular cross section. The fork insertion members 37a and 37b are inserted into the hollow portions, but the square members are stretched for reinforcement.
Since it is such a structure, if cement (concrete) is cast in the mold 3, a plurality of aggregated concrete pseudo-stone blocks 1 corresponding to one mat can be created all at once.

[Manufacture of mats with blocks]
6 to 8, cement (concrete) is placed in each pseudo stone mold 32 of the mold 3 as shown in FIG. 6. However, as shown in FIG. The surface of the bottom part 14 of the pseudolite block 1 shaped by the above is exposed upward, and when the concrete is hardened, a resin mortar 4 which will be described later as an adhesive material is applied to the bottom part 14 with a mortar gun 41.
Next, this manufacturing process will be described in detail.
As an adhesive material used in this example, resin mortar 4 having the composition shown in [Table 1] below was effective from the viewpoint of strength, environmental measures, and mat deterioration prevention.

[Table 1] Composition of resin mortar Sand (35-50) 40% by weight
2. Cement (35-50) 40% by weight
3. Vinyl acetate (15-40) 20% by weight
Subtotal 100% by weight
4). Water appropriate amount (same weight as sand + cement)

In order to block ultraviolet rays, the resin mortar layer must be thick enough (0.3 to 1.5 mm), but sand is an extender for that purpose, but if it is too much, there will be relatively less cement and vinyl acetate. If the strength is insufficient, and if the amount is too small, a large amount of cement and vinyl acetate are consumed, resulting in an increase in cost, so about 35 to 50% by weight is preferable, and preferably 40% by weight. In addition, if the amount of cement is too much, the amount of vinyl acetate is relatively high, and the function of neutralizing and blocking the alkaline component exuding from the concrete is reduced. If the amount is too small, the strength is insufficient, so about 35 to 50% by weight is good. , Preferably 40% by weight.
Furthermore, it is important to use vinyl acetate. Especially, since the vinyl acetate resin layer is formed with sand and cement, it effectively blocks ultraviolet rays. However, if too much vinyl acetate is used, In addition to increasing the height, it is necessary to generate cracks for entering and exiting water during transportation and enforcement work, but it is difficult to generate cracks, and it is also difficult to create water holes by punching. . On the other hand, if the amount of vinyl acetate is too small, the function of blocking ultraviolet rays decreases and the function of neutralizing and blocking alkali components also decreases. Therefore, the amount is preferably about 15 to 40% by weight, preferably 20% by weight. is there. Although vinyl acetate may be about 60% by weight, it is expensive and wasteful, and the above-mentioned composition ratio is appropriate.

However, the portion where the resin mortar 4 is cracked when the mat 2 is curved does not bend at the portion where the bottom surface 14 of the block 1 is fixed, so there is no portion where the concrete between the block 1 and the block 1 exists. Since it bends, a crack is generated between the blocks, so that the function of protecting the mat 2 from the alkaline component remains unchanged. Further, since it is a fine narrow crack, the ultraviolet rays do not reach the lower mat 2 and the blocking action of the ultraviolet rays does not change.
Further, water is mixed to such an extent that it has an appropriate viscosity. In general (in this embodiment), it is preferable to add a weight equivalent to the combined weight of the added sand and cement.
In addition, in the composition of the resin mortar 4, when it takes time to harden the cement of the concrete block, such as in winter, 2 to 6% by weight of calcium chloride as a cement hardening accelerator is mixed as necessary. In this case, the bonding is completed early, and the product demolding time can be advanced.

In the above composition, in the prior art of the above-mentioned Patent Document 4, large stones are mixed in, so that the large stones dive into the mat 2 and act like a wedge on the mat 2 and the pseudo stone block 1 and sand. Adhesive performance has been improved compared to cement and adhesives, but the mat thickness may become uneven due to the mixing of large stones, which may interfere with construction. In the embodiment of the present invention, vinyl acetate having a high viscosity is used in place of the acrylic water-based adhesive, and since the vinyl acetate has a high viscosity, the adhesive strength is stronger and the resin mortar 4 applied to the entire surface is made of The layer is easily and substantially uniformly formed to a thickness of 0.3 mm to 1.0 mm, preferably 0.5 mm.
When this thickness is 0.3 mm or less, the ultraviolet blocking effect is weak, and when it is 1.0 mm or more, the cost of the resin mortar is high, and when water permeability is given to the mat 2 and the resin mortar 4 layers, If it is thin, cracks will easily form and perform the water-passing function. However, if it is thick, cracks will be difficult to occur, and through holes may be provided at appropriate locations on the resin mortar 4 layers with a punching tool. If the mortar 4 layer is too thick, it will take time and effort to form the apertures. (However, as described above, when the mat 2 is gripped and moved, an appropriate crack is generated, which is caused by the passage of water and air. Therefore, it is often unnecessary to provide a through hole), and the flexibility of the mat 2 itself is also lost, and it takes time and labor to perform the work on site.

As shown in FIG. 7, the resin mortar 4 having the above-described composition is bonded to the mold frame 3 (the adhesive material 4 can be detached from the mold frame 3) with the mortar gun 41 and the bottom surface 14 of the pseudo stone block 1. Although the coating is applied all at once, as shown in FIG. 7, the resin mortar 4 of the adhesive material is applied so as to cover the entire surface of the mat 2 for the reason described later. The bottom surface 14 of the block is exposed on the upper surface of the mold 3 and the resin mortar 4 is applied to the exposed bottom surface 14 of the block and the mold upper surface portion 322 of the mold 3 therebetween.
Next, an operation of fixing the pseudo stone block 1 to the mat 2 is performed. As shown in FIG. 8, the non-woven mat 2 having a thickness of about 3 to 6 mm is spread while being pressed against the upper surface of the mold 3. As a result, as shown in FIG. 9 and FIG. 10, the pseudo stone block 1 and the mat 2 are bonded and fixed by the resin mortar 4 of the adhesive material. The mat 2 in which the mat 2 is combined with the concrete pseudo-stone block aggregate that is firmly integrated is removed from the mold 3.

[Demolding device]
Next, the demolding apparatus 5 corresponding to the concrete block assembly mat will be described with reference to FIGS. 11 and 12. The demolding apparatus 5 is provided inside the main body 51 of the demolding apparatus 5, and the outside corresponding to the outer frame 31 of the concrete block mold 3. A frame receiving portion 52 is provided, and the outer frame receiving portion 52 itself is made of hard rubber, and the outer frame receiving portion 52 that receives the frame protection receiving plate 34 made of hard rubber that is stretchable and particularly hard at an appropriate position of the outer frame receiving portion 52. A stop 521 is provided.
The outer frame receiving portion 521 receives the side surface 311 (see FIG. 13) of the outer frame 31 so that the concrete block mold 3 that falls down does not slide on one side in the longitudinal direction of the outer frame receiving portion 52 and moves. 522 is provided. The outer frame receiving portion 521 and the anti-slip portion 522 cannot be struck by hard rubber alone because the frame protection receiving plate 34 on the opposite mold 3 side is made of metal. A metal member 5211 having an L-shaped cross section is disposed on the surfaces of 521 and the non-slip portion 522.
Further, a block receiving portion 53 filled with a sufficiently thick flexible sponge rubber is provided inside the outer frame receiving portion 52 so as to relieve an impact when receiving a concrete block portion, and the surface of the block receiving portion 53 is external. The rainwater is covered with a rubber sheet 54 so that dust does not enter. Similarly, the back surface is covered with a rubber sheet 58.
Since the rubber sheets 54 and 58 are also for protecting the sponge rubber, other vinyl sheets or cloths may be used as long as they have strength, and may be omitted depending on circumstances.

A guide member 55 projecting outward is provided below the longitudinal side surface 511 of the main body 51 of the demolding device 5, and the guide member 55 is formed so as to be inclined to the center in the left and right directions and guided to the center. 551 is provided, and the guided member 36 made of H steel on the mold 3 side is guided to a predetermined position.
Then, as shown in FIG. 12, the forks 61a, b of the forklift 6 are inserted into the fork insertion members 37a, b, the concrete block mold 3 is slightly lifted and moved forward, that is, the position of the dotted line portion in FIG. The guided member 36 on the front side surface of the concrete block mold 3 is moved until it contacts the back side surface 511 of the main body 51 of the demolding device 5.
A pair of tire treads 56a and 56b are provided inside a pair of guide members 55 on the side surface 511 in the longitudinal direction of the main body 51 of the mold releasing device 5, and the tire treads 56a and 56b are provided on the side surfaces 511 in the longitudinal direction. Is provided with a pair of step members 562 on which a pair of tires 62a, b of the fork wrist 6 (see FIG. 14) is placed, and these step members 562a, b are respectively removed by a demolding device connecting portion 561. The mold device 5 is firmly connected to the main body 51.
Therefore, as described above, even if the guided member 36 of the concrete block mold 3 collides with the back side surface 511 of the main body 51 of the demolding device, the weight of the fork wrist 6 itself is below the tires 62a, b. The demolding device 5 is not moved. In addition, what is necessary is just to change suitably arrangement | positioning of the tread member 562 according to the tire width of the working fork list 6.
A pair of handles 57 for moving the demolding device 5 are provided at appropriate positions on the side surface 511 in the longitudinal direction of the demolding device 5.

[Demolding method]
Demolding procedures in the configuration of the concrete block mold 3 and the demolding apparatus 5 as described above will be described.
[Formwork setting process]
As shown in FIGS. 12 and 13, first, the concrete block mold 3 is set at a predetermined location of the demolding device 5.
As shown in FIG. 12, this operation is performed by inserting the forks 61a, b of the forklift 6 shown in FIG. 14 into the fork insertion members 37a, b in the fork insertion members 37a, b of the mold 3 The tires 62 a and 62 b of the fork wrist 6 are moved forward while stepping on the stepping member 562, and the tip 361 of the H-steel guided member 36 of the mold 3 is positioned between both guide side walls 551 of the guide member 55. Further, the guided member 36 is guided along both guide side walls 551, and the tip 361 of the guided member 36 (see FIG. 4 and the like: H steel) abuts against the side surface 511 of the main body 51 of the demolding device 5. In contact therewith, the concrete block mold 3 is set in the step S1 at a predetermined position of the demolding device 5.

[Form reversal process]
Next, the mold 3 is inverted and the concrete pseudo-stone block 1 is removed from the mold 3. First, the forks 61 a and b are removed from the fork insertion members 37 a and b, and the forks 61 a and b are replaced with the mold 3. The bottom surface 381 near one side surface in the longitudinal direction of the mold 3 (the bottom surface near the right side surface in FIG. 13) is pushed up.
In this way, the mold 3 is rotated about the contact portion Z that is in contact with the demolding device 5, but in reality, the mold 3 is rotated about the frame protection receiving plate 34 of the outer frame 31 as in step S2. When the forks 61a and 61b are further advanced and pushed in, the fork 61a and b are brought forward to fall as shown in step S3. As a result, the mold 3 in which the concrete pseudo-stone block 1 is cast as shown in step S4. Falls into the demolding device 5.
At this time, the concrete pseudo-stone block 1 falls from the mold 3 due to the collapsed impact and falls to the block receiving portion 53 filled with a sufficiently thick flexible sponge rubber.
When falling down, the outer frame 31 of the mold 3 is received by the outer frame receiving portion 52, but is not damaged because it is a member made of hard rubber. Further, in order to prevent breakage, the metal frame protection receiving plate 34 on the mold 3 side comes into contact with the outer frame receiving part 521 and the metal member 5211 on the mold releasing device 5 side, and the impact of the outer frame 31 is applied. Absorbs.
If the hard rubber of the outer frame receiving part 52 or the outer frame receiving part 521 is too soft, the concrete pseudo-stone block 1 will not be detached or dropped from the mold 3 and it will be too hard if it is entirely made of metal. The frame 31 and the suspicious stone mold (a rectangular mold (not shown) corresponding to FIG. 16) 32 are often damaged.

[Form removal process]
Since the mold removal itself has been completed in the above-described process, the mold 3 is removed, but the bottom surface (back surface) 38 of the mold frame 3 is the top surface, but the forklift 6 is attached to the fork insertion members 37a, b on the bottom surface 38. 5 and FIG. 5, the concrete block mold 3 is lifted upward, the forklift 6 is retracted, and the forks 61 a, b themselves are rotated to invert the frame 3. As shown in FIG. 6, it is placed in the original state and placed in a predetermined stock yard.
The demolding 3 of the concrete block aggregate mat 2 is completed on the upper surface of the main body 51 on the demolding device 5 side with the mat 2 facing down and the concrete pseudo stone block 1 facing up.
In order to move the completed concrete block assembly mat 2 from the demolding device 5, as described with reference to FIG. 14, the forklift 6 or the like is provided with the grips A and B having no blocks of the mat 2 provided on the forklift 6. The tool 7 may be held and moved.

The above is a description of a mat with a concrete pseudo stone block. However, if the block is an aggregate of concrete blocks, not only the pseudo stone but also a geometrical plane as shown in FIG. One unit block may be a rectangle.
Thus, according to the above-described embodiment, it is not necessary to use a large-scale device such as a vibration device, and a large-sized concrete block assembly mat that collects a large number of concrete blocks into one mat only by the operation of a forklift is provided. It can be easily removed from the form of the concrete block assembly mat and can be operated by one person or a small number of people. In addition, the concrete block frame is less damaged and can be used repeatedly.
Needless to say, the present invention is not limited to the above-described embodiment as long as the features of the present invention are not impaired. For example, although the step member 562 is used to fix the demolding device 5, it may be firmly fixed to the floor or the ground with pegs, anchor bolts, or the like.
