Description

  The present invention belongs to the technical field of a mat with a concrete pseudo-stone block aggregate used for restoration and repair work of a natural environment such as a seawall.

Recently, there is a tendency to place importance on preserving the natural environment, and concrete blocks with pseudo stones used for revetment etc. tend to be used frequently.
Therefore, the applicant of the present invention appears to have irregular arrangement of natural stone-patterned pseudo-stones on the construction surface, and the joint lines are not straight but show irregular lines so that the joint soil will not be washed away by rainwater flowing on the construction surface. A concrete pseudo-stone block devised so that grass and small shrubs grow and natural destruction is kept to a minimum is provided (Patent Document 1). In addition, in order to simplify the construction of a natural stone-patterned concrete pseudo-stone block at the seawall, the pseudo-stone block is made small, the pseudo-stone arrangement on the construction surface looks irregular, and the joint line is also linear. There is proposed a mat with a concrete pseudo-stone block aggregate which is devised so as to prevent the earth and sand of the joints from being washed away by rain water or the like which exhibits irregular lines and flows on the surface of the pseudo-stone block (Patent Document 2).

However, the pseudo stone block as disclosed in the above-mentioned Patent Document 1 and Patent Document 2 has a block substrate itself that is approximately rhombus, and its arrangement is limited to the pseudo stone on the block substrate, resulting in a fixed pattern. It was difficult to bring the landscape close to nature when laying down.
In addition, the connecting lines between the blocks become complicated, and it takes time to arrange the blocks by hand at the site. In particular, as shown in Patent Document 2, when the blocks are made small and made into a mat with a pseudo stone block aggregate made of concrete. When joining, even if the joining line is shifted by 1 cm, the boundary becomes conspicuous, and if the joint surface of the block assembly of the block assembly-attached mat and the block assembly-attached mat becomes complicated, while confirming the joining manually, one by one It had to be done, and it was a problem from the work efficiency.
Prior art patent document 3 has a problem that the joining section is simple and the joining line is conspicuous as a whole. In addition, since the blocks are made of concrete, they are heavy when assembled, making transportation and construction cumbersome, and if the pseudo stone block itself cannot be folded, it is difficult to handle the mat. It was.
In particular, if the pseudo stone block is made thinner (about 4cm) than the conventional one to make the entire mat lighter, the outline and joints of the pseudo stone block will be closer to the surface of the pseudo stone block, making it more noticeable. There was a point.
Japanese Patent No. 2881642 Japanese Patent Application Laid-Open No. 2004-255765 Japanese Patent Application No. 2005-518385

  The present invention has been made in view of the above-mentioned problems, and the problem is that in the mat with a concrete pseudo-stone block aggregate, the entire aggregate mat is made lighter and more flexible. 1. Make the polygons with a basic section of a quadrangle or more and have a depression, make it an irregular line that harmonizes with the natural landscape, make the top surface of the pseudo stone block complex and harmonize naturally, and make the boundary of the pseudo stone An object of the present invention is to provide a mat with a set of concrete pseudo-stone blocks that is inconspicuous and facilitates the work of joining together when the blocks are assembled.

In order to solve the above-mentioned problems, the invention according to claim 1 is a mat with a set of concrete pseudo-stone blocks, wherein the plane provided on the mat is an irregular polygon having four or more recesses. The outline of the basic section is a straight line having an inclination of 45 degrees and a multiple of 45 degrees, and the basic section has a shape that covers the mat as a whole in close contact with the other basic sections. Necessary basic divisions are displayed with an identification mark on the pseudo stone block or displayed on the construction drawing corresponding to the pseudo stone block, and any number, arrangement, and size of the mat ground are not exposed in each basic division. A pseudo stone block base is arranged, the top surface shape of the pseudo stone block is an arbitrary complicated shape including a curve different from the shape of the base, and the inclination angle of the side surface connecting the base and top surface shape of the pseudo stone block is a steep slope 45. If the side surface becomes a warm slope of 45 degrees or less, a shelf portion is provided in the middle of the side surface, and the slope angle of the side surface other than the shelf portion is set to a steep slope of 45 degrees to 80 degrees. This is a mat with a pseudo stone block aggregate made of concrete, characterized in that the external shape of is complicated.
The invention according to claim 2 is the mat with concrete pseudo-stone block aggregate according to claim 1 or 2, wherein the polygons of the basic section are two kinds of polygons which are point-symmetric.
According to a third aspect of the present invention, when the mat is cut and joined at the time of construction of the mat, the outline line of the basic section displayed in advance is searched so as to match the outline line of the mat to be joined. It cut | disconnects along and, It is a mat | matte with the concrete pseudo stone block aggregate | assembly of Claim 1 or 2 characterized by the above-mentioned.

According to the present invention, in a mat with a set of concrete pseudo stone blocks, an arbitrary number, arrangement and size of pseudo stone block bases are arranged so that the mat ground is not exposed in the basic section on the mat. Since the top surface has an arbitrarily complex shape that includes a different curve from the shape of the base, the appearance is complicated, and even if the pseudo stone block is thin, the boundary line (joint) between the bases is too conspicuous as a whole It can be designed to harmonize with the natural landscape, and further, the pseudo stone block can be finely divided and the mat can be bent slightly in the joint groove, improving the flexibility of the entire mat, Construction becomes easy.
In addition, since the basic section of the pseudo stone itself is a complex polygon having four or more sides, the basic section itself is complicated and harmonizes with the natural landscape.
Furthermore, when joining a plurality of this assembly mat, if the basic section required in advance is cut along the display on the pseudo stone block with an identification mark, or the construction drawing corresponding to the pseudo stone block, Construction on site is also easy. In addition, since the joining surface can be configured to be a flat plane mainly at 45 degrees, 135 degrees, the slope serves as a guide, and the joining surfaces can be easily matched and joined.

A preferred embodiment of a mat with a concrete pseudo stone block aggregate according to the present invention will be described with reference to the drawings.

[Basic division]
A basic section 3 made of an irregular polygon having depressions of four sides or more is provided on a plane which is the upper surface of the mat in contact with the bottom surface 26 of the pseudo stone block 2 of the mat 1, and the outline of the basic section is 45 degrees. And a straight line having an inclination of a multiple of 45 degrees, and the basic section 3 is in close contact with the other basic sections (Fig. 4.3 ', 3'', 4, 4' ...) as a whole. The mat 1 is covered.
First, the basic section 3 on the plane of the mat 1 will be described with reference to FIG. 1 (a). The first basic section 3 as a whole is a non-constant section composed of 16 sides with apexes from horizontally long signs a to q. As shown in FIG. 1A, the first side [ab] is a straight line parallel to the vertical frame line 11 of the rectangular mat 1, and the second side [bc] is the first side. The third straight line [cd] is a 90-degree straight line perpendicular to the vertical frame line 11 of the rectangular mat 1 (parallel to the horizontal frame line 12 of the rectangular mat 1), and the fourth side [cd]. de] is a 135-degree inclined straight line with respect to the first side, the fifth side [ef] is parallel to the vertical frame line 11 and a 0-degree straight line, and the sixth side [fg] is similarly a 135-degree inclined straight line, The seventh side [gh] is parallel to the vertical frame line 11 and is a 0-degree straight line, the eighth side [hi] is similarly a 135-degree inclined straight line, and the ninth side [ij] is parallel to the vertical frame line 11. The 10th side [jk] is a 90 degree straight line perpendicular to the vertical frame line 11, the 11th side [kl] is similarly a 135 degree inclined straight line, and the 12th side [lm] is the vertical frame line 11.

Is a straight line of 0 degree parallel to the vertical frame line 11, and the 16th side [qa] is an inclined straight line of 135 degrees similarly.
Here, the lengths of the horizontal first side [ab] and the thirteenth side [nm] are equal to each other. Similarly, the fifth side [ef] and the seventh side [ij], and the right-angled third side [cd] and the third side [cd] 12 sides [lm], 6th side [fg] and 8th side [hi] of skew, 14th side [np] and 16th side [qa], 4th side [de] and 11th side [kl] The lengths of are equal.

When the second basic section 4 and the first basic section 3 are plotted as point symmetry with x0 as a fixed point in FIG. 1, a figure as shown in FIG. 1B is obtained. The basic section 4 of the first basic section 3 has vertices a ′ to q ′ with x0 as a fixed point from the vertices a to q of the first basic section 3, and the order is only reverse to that of the first basic section 3. The same.
Since the first basic section and the second basic section are point-symmetric, that is, the shape obtained by turning the first basic section upside down becomes the second basic section, as shown in FIG. The ninth side [i′j ′] of the second basic section 4 is in close contact with the fifth side [ef] on the lower side of one basic section 3, and similarly, the seventh side [ij] on the lower side of the basic section 3 is set. ] Is the fifth side [e′f ′] of the basic section 4, and the sixth side [fg] of the basic section 3 is the eighth side [h′i ′] of the basic section 4 is the eighth side of the basic section 3. The sixth side [f′g ′] of the basic section 4 comes into close contact with [hi].
Similarly, the 13th side [m′n ′] on the lower side of the second basic section 4 is in close contact with the first side [ab] of the next first basic section 3 ′, and FIG. 4 and FIG. As shown, there is no gap in the vertical direction and the mat 1 is laid so that the ground is not exposed.
Also in the left-right direction, the third side [cd] of the next first basic section 3 ″ is placed on the twelfth side [lm] of the first basic section, and the next basic is placed on the eleventh side [kl]. The fourth side [de] of the section 3 ″ is in close contact with the tenth side [jk] and the next basic section 4 ″, the tenth side [j′k ′], and there is no gap in the left-right direction. Is laid out so as not to be exposed.

By combining the first basic section 3 (3′3 ″...) And the second basic section 4 (4′4 ″...) In the vertical and horizontal directions, as shown in FIG. In addition, both basic sections 3 and 4 are laid on the mat 1. Thus, both basic sections 3 and 4 are 16 sides which are four sides or more, and the hollow part which has a slope like the outline of the 5th side [ef] and the 6th side (FIG. 4: 2A) and It consists of an irregular polygon having a trapezoidal convex part (FIG. 4: 2B), and the entire outline of the basic section also includes a straight line parallel to or perpendicular to the vertical frame line 11 or the horizontal frame line 12 of the edge of the rectangular mat 1. And a straight line having an inclination of an angle of multiples of 45 degrees and a multiple of 45 degrees (135 degrees), and correspondingly, the lengths of the sides to be joined are made equal to each other so that the two basic sections 3 and 4 have a point-symmetric shape, that is, mutually If the shapes are matched in the inverted state, the mats 1 can be arranged so that the ground of the mat 1 is not exposed to the outside when the two basic sections 3 and 4 are spread.
In addition, when laying the pseudo stone block 2 on the mat 1, a plurality of pseudo stone blocks 2 corresponding to the two basic compartments 3 and 4 are produced in advance, and the pseudo stone blocks for each of the two basic compartments 3 and 4 are turned over and arranged. A known fixing means, that is, an adhesive is applied to the back side of the pseudo stone block 2 and fixed to the mat.

[Basic division and artificial stone block]
Next, the pseudo stone block 2 arranged in the two basic sections 3 and 4 will be described. First, the conventional pseudo stone block always has a base portion and the pseudo stone is placed on the base portion. In the mat with an aggregate, since the mat 1 is a mat 1 that collects a large number of pseudo stone blocks 2, the weight is increased. Is thinning.
Basically, the relationship between the basic block and the pseudo-stone block is basically a pseudo-stone block of any number, arrangement, size, and height, as long as it is placed in the two basic divisions 3 and 4. There is no hindrance to cutting and joining of the mat 1.
In addition, the basic sections 3 and 4 can be formed as one pseudo-stone block, but the flexibility of the mat 1 is lost because there is no place to bend because it is too large. Therefore, the pseudo-stone block 2 in the basic sections 3 and 4 needs to be divided into several pseudo-stone blocks 2. In addition, the joint part of the boundary line of the pseudo stone block 2 can be divided with the slope reaching the mat 1, but this joint part has a drainage groove for rainwater or the like at intervals of 5 to 6 mm. Close to the natural state. Furthermore, since the pseudo stone block 2 is made of concrete, and further, the pseudo stone block 2 is collectively produced by a plurality of pseudo stone molds 61 (described later), the joint portion interval 5 must be about 5 to 6 mm.
However, when the same shape in the basic sections 3 and 4 is the upper surface shape of the pseudo stone block, the outline of the basic sections 3 and 4 becomes conspicuous and unnatural. Therefore, in the embodiment of the present invention, the contour lines of the basic sections 3 and 4 and the contour lines (joints) of the pseudo stone block base 2a of the several pseudo stone blocks 2 in the basic sections 3 and 4 are not conspicuous. Lines and joints are not the same as the shape of the upper surface 2b of the outer shell wire pseudo-stone block 2, and the contour lines (joints) are conspicuous even if the side slope is gentle, so the slope of the slope is steep (45 ° C or less) This will be described with reference to FIGS. 2 and 3.

The basic section 3 and the basic section 4 in FIG. 1 are the same as the upper half basic section 3 and the basic section 4 in FIG. 2, but the shape, arrangement, and size of the base 2a of the pseudo stone blocks 21 to 25 in FIG. Are different from the base 2a and the upper surface shape 2b of the plurality of pseudo stone blocks 2 in FIG. 1 (the number happens to be the same). As described above, for example, the shape and arrangement of the pseudo stone blocks 2 in the basic section 3 are as follows. The base 2a and the upper surface shape 2b of the plurality of pseudo stone blocks 2 are different in shape, size, arrangement, (number), etc., but here, the pseudo stone in the basic section 3 is different from FIG. The block 2 will be described.
In the basic section 3 of FIG. 2, relatively large pseudo stone blocks 21 and 22, a medium pseudo stone block 23, and small pseudo stone blocks 24 and 25 are arranged. The outline of the base 2a of the pseudo stone block is shaped so as to be in contact with each other as much as possible with a distance of about 5 mm, and the outline is a geometric pattern consisting of a straight line. This is when carrying a mat with a concrete pseudo stone block aggregate. 11, when the construction is performed, as shown in FIG. 11, the outer edge of the pseudo stone block base 2 a rubs with the curvature of the mat 1, so that it is easy to break in a complicated curve and the strength of the combination of straight lines can be maintained. . Further, as another advantage of making the outline shape of the base 2a of the pseudo stone block 2 into a geometric pattern composed of a straight line, the design and demolding of the formwork in the basic sections 3 and 4 are simplified.
One of the features of the present invention is that the basic sections 3 and 4 are a combination of straight lines, and even if the contour line of the base 2a of the pseudo stone block 2 is also a linear geometric shape, the pseudo stone block 2 of the basic sections 3 and 4 The upper surface 2b of the base plate 3 has an arbitrary complicated shape including a curve different from the shapes of the basic sections 3, 4 and the base 2a, and the inclination angle (average slope) of the side 2c connecting the base 2a and the top 2b of the pseudo stone block 2 to the edge. When the side surface 2c becomes a warm slope of 45 degrees or less, the shelf portion 2d is provided in the middle of the side surface. The inclination angle of the side surface 2c other than the portion 2d is set to 45 to 80 degrees which is a steep slope, and the interval 5 is set in a deep position so as not to be noticeable.
In other words, in order to make the complicated top surface shape 2b different from the shapes of the basic sections 3, 4 and the base material 2a, the inclination angle of the side surface 2c that inevitably connects the base 2a of the pseudo stone block 2 and the edge of the top surface 2c is varied. However, for the slanted slopes, it is necessary to make the slopes of all the slopes 45 to 80 degrees by providing the shelf 2d. This is because if the inclination angle is 80 degrees or more, it is difficult not only to remove the pseudo stone block 2 from the mold 6 but also the joints between the pseudo stone blocks 2 cannot function as rainwater drainage grooves. This is because, when the temperature is 45 degrees or less, the outlines (joints) of the basic sections 3 and 4 and the base 2a are located near the surface of the pseudo stone block 2 and are not harmonized naturally.
The basic section 4 in FIG. 1 and the basic section 4 in the lower half of FIG. 2 are the same, and the pseudo-stone block 2 in the basic section 4 has the same technical meaning as the pseudo-stone block in the basic section 3. Therefore, it is omitted.

Here, the inclination angle of the side surface 2c and the shelf portion 2d in the middle of the inclined surface will be described.
In the upper half basic section 3 in FIG. 2, the cross-sectional view along the line AA is FIG. 3A, the cross-sectional view along BB is FIG. 3B, and the cross-sectional view along CC is It is FIG.3 (c).
By the way, since the mat with a concrete pseudo-stone block aggregate of the present embodiment is an aggregate mat, the individual pseudo-stone block is made as thin as possible to reduce the weight of the entire mat. The base part of the pseudo stone block 2 is eliminated and the height of the pseudo stone block 2 is set to about 3 to 5 cm. Since this is low, the contour line (joint) of the pseudo stone block becomes more conspicuous than before. However, the distance 5 between the perimeter stones 2 in the basic sections 3 and 4 and the several pseudostone blocks 2 in the basic sections 3 and 4 is due to the restrictions on the production of the concrete pseudostone block 2. This is because it is difficult to fix the pseudo stone block 2 when aligning the mat 1 if the interval 5 is too uneven. In order to reduce the weight, it is better to make the pseudo stone block 2 as thin as possible. However, if it is 3 cm or less, the surface of the pseudo stone block 2 has unevenness and it is not easily broken, and if it is 5 cm or more, the concrete pseudo stone block. Since the mat with aggregate as a whole becomes considerably heavy, the height of the pseudo stone block 2 is preferably about 3 to 5 cm as described above, and more preferably about 4 cm.

First, as shown in FIG. 3A, the right side portion of the large pseudo stone block 21 has a side surface 2c extending from the base 2a in contact with the mat 1 to the edge of the upper surface 2b and is linear with an average angle of about 75 degrees. The steep slope (side surface) 2c is formed, and the left side portion of the large pseudo stone block 22 also forms a straight steep slope (side surface) 2c with an average angle of about 75 degrees from the base 2a to the upper surface 2b. In this case, the distance 5 between the two blocks is in a deep position on the steep slope, and the joint itself is not very noticeable.
Next, as shown in FIG. 3 (b), when one of the opposing slopes is a slope with a slight inclination angle, the right-side portion of the large pseudo-stone block 21 extends substantially from the base 2a to the edge of the upper surface 2b. A straight steep slope 2c is formed at an average angle of about 72 degrees, and a left side portion of the small pseudo stone block 24 is a gentle slope from the edge of the base 2a to form a straight slope (side surface) 2c at an average angle of about 50 degrees. As shown in the figure, on a steep slope having an angle of about 50 (45 degrees or more), even if the height of the pseudo stone block 2 is as low as 4 cm, the interval (joint) 5 does not stand out so much.

Further, as shown in FIG. 3 (c), if the slope 2c ′ (broken line portion) directly connecting the edge of the upper surface 2b of the pseudo stone block 2 and the edge of the base 2a becomes a warm slope of 45 degrees or less, Since the pseudo stone block of the example is as low as about 4 cm, even an interval (joint) of about 5 mm is close to the surface of the pseudo stone block, and this interval 5 is conspicuous.
Therefore, the side surface in the vicinity of the interval (joint) is steeply inclined (average 70 degrees, 55 degrees), and the interval 5 is located in the back so that it is not conspicuous from the outside. And a steep slope is formed again on the edge of the upper surface shape 2b at a position away from the edge of the base 2a on the plane.
To explain this, the right-side portion of the large pseudo-stone block 22 is provided with a horizontal and flat intermediate shelf portion 2d at a substantially intermediate height from the bottom surface 2a, and an approximately average angle from the edge of the base 2a to the edge of the intermediate shelf portion 2d. A straight slope 2c is formed at about 70 degrees, and further, a straight slope 2c is formed at an average angle of about 65 degrees across the edge of the upper surface shape 2b from the slope rising part deep in the intermediate shelf 2d, On the other hand, the left side portion of the small pseudo stone block 25 also forms a straight steep slope 2c at an angle of about 55 degrees from the base 2a to the edge of the intermediate shelf 2d at an intermediate height, and further from the intermediate shelf 2d to the upper surface 2b. A straight steep slope (side surface) 2c is formed at an angle of approximately 62 degrees.
With such a slope configuration, even if the height of the pseudo stone block 2 is as low as about 4 cm, the interval 5 does not stand out so much.

In the production process of the pseudo stone block (formwork or the like) of the present embodiment as described above, the setting of the pseudo stone block in the basic section 3 in FIG. 2 will be described in order.
(1) First, the shape of the base 2a of the desired pseudo stone block 2 (21 to 25), here, the 5 pseudo stone block 2 in the basic section 3 is divided into almost straight lines.
(2) Next, in each base 2a, the shape of the upper surface 2b of any complicated pseudo-stone block 2 is determined. At this time, the surface of the pseudo stone block 2 and the shape of the upper surface 2b are designed so as to harmonize as naturally as possible by using many curves so as to be close to natural stone.
(3) Although the upper surface shape of the pseudo stone block in (2) is almost different from the shape of the base, it connects the outline of the base 2a of the pseudo stone block 2 and the edge of the shape of the upper surface 2b. If the side surface is designed, but the inclination angle is formed in the range of 45 to 80 degrees and does not fall within this range, the shelf 2d is placed in the middle of the side surface 2c as described in FIG. And the inclination angle of the side surface other than the shelf 2d is formed in the range of 45 to 80 degrees.
At this time, if the shape becomes too unnatural as a whole, the partition shape of the base 2a of the pseudo stone block 2 or the shape of the upper surface 2b may be changed.
(4) Thereafter, the same operation is repeated to form a complex and versatile slope to form an aggregate of pseudo stone blocks 2 that are more naturally harmonized.
In addition, the setting of the angle of this slope needs to form the slope of the pseudo stone block of the outline of the basic divisions 3 and 4 similarly.
In this way, if the inclination of the side surface of each pseudo stone block is set, the outline of the basic section, the outline of the boundary of the pseudo stone block in the section will not be conspicuous, the joint will be complicated, and as a whole Harmonize with the natural landscape.

[Mat joining]
FIG. 4 shows a corner portion of the mat 1 with the concrete pseudo-stone block aggregate, and the whole is shown in FIG. 5. Both ends 1a and 1b of the mat 1 are exposed, and as shown in FIG. The parts 1a and 1b are gripped by a gripping tool 81 of a transporting device 8 such as a crane and suspended to move.
Here, the outer lines 2X and 2Y at the end of the joint portion of the pseudo stone block 2 of the mat with an aggregate 1 are, as shown in FIG. 4, the horizontal (2X) direction and the vertical (2Y) in FIG. Since each of the direction is composed of an inclined surface of 45 degrees or 135 degrees and a flat surface, the angles of the inclined surfaces are 45 degrees and 135 degrees with respect to the horizontal line (vertical line), and the depression (2A ) And the trapezoidal convex part (2B) opposite to each other, the joints (2X, 2Y) at the basic sections 3, 4 where the pseudo stone blocks 2 of the mat 1 are arranged from the left or right side of the drawing or the top and bottom sides of the drawing are cranes. Even if it is suspended by 8 and moved and approached, the slope depression (2A) serves as a guide and is smoothly guided to a predetermined location. As shown in FIG. To the outline 2Y at the end of the mat overlap portion 1c in the horizontal direction of the mat 1 (A) Then, the outer edge 2Y of the outer edge (pseudostone block 2) 1d of the mat 1B (1C, 1D) to be joined coincides with each other, and it becomes indistinguishable from other pseudo stone block aggregate surfaces after construction.
In the above description, the case of joining is described. However, when the mat is cut too long in both the vertical and horizontal directions, conversely, the gap (outline) that also serves as the drainage groove of the pseudo stone block of the zigzag basic sections 3 and 4 described above. ) If it cut | disconnects by 5, since this part is only a nonwoven fabric of a fiber, it can cut easily.
In this case, a necessary basic section is displayed with an identification mark on the pseudo stone block in advance, or a construction drawing in which the basic section is displayed together with the arrangement of the pseudo stone block is prepared, and the displayed basic section 3, For example, the outline 1d shown in FIGS. 5 and 6 can be obtained by cutting along the interval 5 (outer outline, joint portion).

As shown in FIG. 7, the manufacturing method of the mat 1 with the concrete pseudo-stone block aggregate in the present embodiment is as many as the formwork 61 as many as the pseudo-stone blocks 2 of the plurality of basic sections 3 and 4 mounted on the mat 1. The block assembly mold 6 is provided with a large outer frame 62 around the assembly of the molds 61 of the plurality of pseudo stone blocks 2. The outer frame 62 is made of FRP resin, and the pseudo stone mold 61 for forming the inner pseudo stone is made of polyurethane resin, and cement is placed on the mold 6 to collectively put a plurality of concrete pseudo stone blocks corresponding to one mat at a time. And create it.
Of course, it is possible to create the pseudo stone blocks 2 one by one. However, as shown in FIG. 7, concrete is placed on the mold 61 of each pseudo stone of the mold 6 so that the shaped pseudo stone block 2 is formed. When the concrete is solidified, the adhesive material 7 is sprayed on the bottom of the base 2a of the pseudo stone block 2 with the mortar gun 71 when the concrete is hardened. As shown in FIG. The nonwoven fabric mat 1 of about 6 mm is laid down while being pressed against the upper surface of the mold 6, and as shown in FIG. 10, the adhesive material 7 is applied to the entire surface of the pseudo stone block 2 and the mat 1 and bonded and fixed. In order to accelerate the curing of the adhesive, steam curing is performed by spraying hot steam, and when the curing is completed, the mat with the pseudo stone block made of the concrete with the pseudo stone block 2 and the mat 1 is removed from the mold 6. If you mold, Cleat made of cast stone block assembly with a mat 1 can be raised.

In addition, the following composition was effective for the adhesive material 7 used with the mat 1 of the present embodiment in view of strength and environmental measures.
1. 20-27% by weight of sand
2. Large stone (diameter 4-5cm) 15-22% by weight
3. Cement 35-47% by weight
4). Acrylic aqueous adhesive (adhesive other than epoxy) 2-6% by weight
5). Calcium chloride (cement hardening accelerator) 2 to 6% by weight
6). Appropriate amount of water In the above composition, (1) By mixing large stones with a diameter of about 2 to 5 cm, preferably about 4 to 5 cm, the large stones dive into the mat 1, and the mat 1 and the pseudo stone block 2 acts like a wedge, and the adhesion performance is significantly improved as compared with sand, cement and adhesive. This is because sand, cement and adhesive strengthen the surface only, so it is considered that the main body is peeled off when it is pulled, and the surface can be prevented from peeling off. There is not much effect in improving the strength, preferably 4 cm or more is more effective. Conversely, if it is 5 cm or more, the thickness of the adhesive layer becomes too large and the whole becomes heavy, and a large amount of adhesive material is required. This is uneconomical and is preferably 5 cm or less. In addition, (2) the epoxy adhesive that has been used in the past has an adverse effect on the environment, so acrylic water-based adhesives were used, which allows steam curing to accelerate cement hardening by spraying steam, This contributes to improving the efficiency of work in cold regions. Furthermore, (3) Admixing of cement hardening accelerator (calcium chloride) is completed at an early stage, and the demolding time of the product can be advanced.

The adhesive material 7 is sprayed together with the mortar gun 71 on the mold 6 (the adhesive material 7 can be detached from the mold 61) and the bottom of the pseudo stone block 2, but the spraying method is based on the relationship with the mat. As shown in FIG. 10, the adhesive material 7 is spread on the entire surface of the mat 1 so as to cover the bottom surface of the pseudo stone block.
In this embodiment, it is sprayed on the entire surface G of the mat 1, but the adhesive used is an acrylic aqueous adhesive (adhesive other than epoxy), and after fixing the pseudo stone block 2 to the mat 1, The mat gripping portions 1a and 1b are gripped by a crane (if necessary, refer to JP 2004-255765 A above), transported, moved, and constructed, and the mat 1 is always bent into an arc shape. The agent will crack properly.
This crack creates a part where the adhesive material 7 does not exist because the water moves and the plant grows. However, it is not necessary to make the coating amount of the adhesive material too thick, but rather a crack penetrating vertically occurs. A thickness of about a degree is preferable.
In this way, the adhesive material 7 that causes cracks is not sprayed so that the plants do not grow completely, but rather, the cracks are caused to allow water to move, and the soil is also deposited and the soil is deposited. Although it is possible for the roots to enter and the plant to grow, it is not preferable that too much weed grow. In this case, the mat 1 and the adhesive material 7 cause some weed to grow. It is difficult.

As described above, the mat 1 with the pseudo stone block aggregate according to the present embodiment allows the pseudo stone block to be freely arranged in the basic sections 3 and 4 as compared with the conventional mat with the block aggregate made of concrete. The boundary line between each other can be a complex joint groove, and the width of the joint groove is almost the same, so that it does not stand out as a whole and can be designed to match the natural landscape. Since the blocks can be divided finely and the mat can be bent slightly in the joining groove, the flexibility of the entire mat is improved, and the mat can be transported and installed easily.
In addition, because the basic section of pseudo stone itself is a complex polygon with 16 sides of 4 or more sides, the basic section itself becomes complex and harmonizes with the natural landscape, and the loss of the land can be prevented, and It is easy to join, and even if the adjacent mats are displaced, it does not stand out, the top surface is flat and has a natural stone pattern, so it is suitable for walking and watering by workers and after completion. Can be manufactured inexpensively.
In addition, when joining a plurality of the mats 1, the necessary basic section is displayed in advance with an identification mark on the pseudo stone block, or the line of the basic section corresponding to the pseudo stone block is displayed on the construction drawing. If it cuts along, construction on the site will become easy. In addition, the joint surface is mainly a 45 °, 135 °, flat polygon with a dent on the flat plane, so the dent and the inclined side surface can be used as a guide, and the joint surface can be easily matched. Because it is an easy and irregular polygon, it will not stand out even if the adjacent mats are displaced, and the top surface is flat and natural stone pattern, so it will be slip resistant and workers and people walking on the waterside after completion Suitable and inexpensive to manufacture.
Of course, the present invention is not limited to the above-described embodiment as long as the features of the present invention are not impaired.
