Description

  The present invention belongs to a technical field of a mat with a concrete block provided with a fixed concrete block or a pseudo stone block used for restoration and repair work of a natural environment such as a seawall, and a manufacturing method thereof.

Recently, mats with a lot of concrete blocks on the revetment etc. have been used for ease of implementation.
Conventional mats with concrete blocks are mats that are fixed on a mat using anchor pins, screws, or other connecting tools, and then spread on the revetment during construction, and concrete block construction methods (patented) Document 1) has been proposed. Furthermore, a construction method (Patent Document 2) has been proposed in which an epoxy resin adhesive is applied to the bottom surface of a plurality of concrete blocks and fixed to a mat, and is constructed on a revetment. In addition, a method has been proposed in which a sheet is pressed and fixed to a sheet while the concrete is in an uncured state when the concrete block is molded (Patent Document 3).

Therefore, the present inventor has observed irregular arrangement of the natural stone pattern pseudo stones on the construction surface, and the joint lines are not linear but show irregular lines so that the earth and sand of the joints are not washed away by rain water flowing on the construction surface. In this pseudo-stone block concrete formwork, multiple molds have been developed so that the formwork is arranged at the time of construction. When the frames are arranged in a lump and concrete is poured, the bottom surface of the pseudo stone is exposed on the top surface of the mold, and the exposed bottom surface of the pseudo stone is kneaded with cement mixed with large stones and acrylic water-based adhesive. With a concrete pseudo stone block that applies adhesive, spreads a water-permeable non-woven mat on the mat, fixes the pseudo stone to the mat, and then demolds the pseudo stone together with the mat from the formwork It has to offer Tsu door (Patent Document 4).

  As for the mat with a concrete block disclosed in Patent Document 1, there is known a method in which a plurality of concrete blocks are fixed to a sheet, and the sheet with the concrete block is spread on a construction site, as shown in FIG. In addition, when the concrete block a is fixed to the sheet b, the worker fixes the sheet by inserting an anchor pin (staple) or a screw (screw) connector c from the surface of the sheet b for each concrete block a. Although each work must be done manually, there is a problem that although the work efficiency is slightly increased, the work efficiency is still poor and a lot of time must be spent. Also disclosed in Patent Document 2 As shown in FIG. 14, the technique is to create concrete blocks a one by one and Adhesive d is applied to the bottom of the lock a and fixed to the mat. However, the adhesive d must be applied to the bottom of the concrete block a, requiring time and effort, and the concrete block a is usually heavy. Therefore, an epoxy resin adhesive is used as the adhesive d, but it is known that the cost is high and the environment is also adversely affected. In order to accelerate curing, steam curing is necessary. However, heating with a heater can only partially heat it, and it is almost impossible to warm the whole to the average. There is a problem that it is difficult and expensive to shorten the length. Furthermore, the technique disclosed in Patent Document 3 is a method in which a concrete is uncured and the sheet is stretched and cured with steam while the concrete block is molded. However, there was a problem that the block was easily detached because the strength was not so high.

The adhesive for mats with a concrete block disclosed by the present inventor in Patent Document 4 cannot be used because the epoxy resin has an adverse effect on the environment. Therefore, an acrylic water-based adhesive that has little influence on the environment is used. ing. However, since acrylic water-based adhesives are water-based and have low viscosity, it is difficult to increase the thickness of the adhesive layer, and the adhesive strength is also weak.For this reason, cement and acrylic water-based adhesive mixed with large stones on the bottom of the exposed pseudo stone are kneaded. The large stone is applied to the bottom of the pseudo stone and the water-permeable non-woven mat to improve the adhesion, but it requires materials and labor to mix the large stone. There was a problem to do. In addition, since the acrylic aqueous adhesive is applied in a streaky manner, the application work is also troublesome.
By the way, the mat material of the mat with the concrete block is generally a non-woven fabric of polypropylene fiber, polyester fiber, polystyrene fiber, or a non-woven fabric obtained by blending these, but for polypropylene, these mats are used outdoors. Therefore, there is a problem that it deteriorates when exposed to ultraviolet rays, and polyester and polystyrene have a problem that they are weakly deteriorated by an alkali component that exudes from a concrete block.

  The present invention has been made in view of the above-described problems, and the problem is that a plurality of concrete blocks corresponding to one mat are created at a time to simplify construction on a concrete revetment. Furthermore, another object of the present invention is to provide a mat with a concrete block that prevents the block from being detached from the mat and prevents deterioration from ultraviolet rays of the mat material and alkali components of the concrete, and a method for producing the same.

In order to solve the above-mentioned problems, the invention of claim 1 is a mat with a concrete block, which is a plurality of form blocks for a concrete block, wherein the form forms are arranged in the construction. When the concrete is poured, the bottom surface of the block is exposed on the upper surface of the mold, and sand, cement, vinyl acetate, And apply resin mortar kneaded with water, and lay a water-permeable nonwoven fabric mat of polypropylene fiber, polyester fiber, polystyrene fiber, or a water-permeable nonwoven fabric composite of these, and fix the block to the mat. The block is removed from the mold together with the mat after being fixed.
The invention according to claim 2 is the mat with a concrete block according to claim 1, wherein a fine crack is generated in the resin mortar layer between adjacent blocks on the mat after demolding.

According to a third aspect of the present invention, there is provided a method for manufacturing a mat with a concrete block, wherein a plurality of concrete block molds are formed, and the molds are integrally formed by arranging a plurality of molds so as to be arranged at the time of construction. When the concrete is poured, the bottom of the block is exposed on the top surface of the mold, and the exposed bottom of the block and the top of the mold are kneaded with sand, cement, vinyl acetate, and water. A resin mortar is applied, a nonwoven fabric mat of water-permeable synthetic resin fibers is laid on the resin mortar, the block is fixed to the mat, and the block is removed from the mold together with the mat after fixing.
According to a fourth aspect of the present invention, there is provided a method for manufacturing a mat with a concrete block, wherein the plurality of concrete block molds are integrated into a plurality of mold frames so that the molds are arranged at the time of construction. When the concrete is poured, the bottom of the block is exposed on the top surface of the mold, and the exposed bottom of the block and the top of the mold are kneaded with sand, cement, vinyl acetate, and water. A resin mortar is applied, and a water-permeable nonwoven mat made of polypropylene fiber, polyester fiber, or polystyrene fiber, or a water-permeable nonwoven mat that is a composite of these, is spread on the mat, and the block is fixed to the mat after fixing. It is characterized by demolding the block together with the mat.
The invention of claim 5 shows that the resin mortar layer between adjacent blocks on the mat is caused to have a fine crack by causing the mat after demolding to be curved and flat. It is a manufacturing method of the mat with a concrete block of Claim 3 or 4 characterized by the above-mentioned.

As described above, according to the present invention, a mat with a pseudo stone block that can be easily installed on a revetment of concrete, and a plurality of concrete blocks corresponding to one mat can be obtained by placing cement in a formwork. It can be created in a batch according to the arrangement at the time of construction, and it has become a water-permeable nonwoven mat of synthetic resin fibers, allowing water to enter and exit between the blocks, nurturing plants and promoting greening of the revetment Furthermore, when polypropylene fibers and non-woven mats mixed with these are used, deterioration due to ultraviolet rays is prevented, and when polyester fibers, polystyrene fibers and non-woven mats mixed with these are used, the fibers exude from concrete. Deterioration due to a chemical reaction of the alkali component can be prevented.
In particular, in the inventions of claims 2 and 5, the resin mortar layer is prone to crack in the mat transfer and transport process, but dare to use a water-permeable nonwoven mat by causing cracks in the resin mortar layer. Together with this, water can enter and exit between the blocks, and plants can be nurtured to promote greening of the revetment.

Here, concrete mats with blocks suitable for the present invention, in particular, mats with concrete pseudo-stone concrete, and an example of the manufacturing method thereof 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.

The mat 2 with a concrete pseudo-stone block (see FIG. 7) of this embodiment is a non-woven fabric of polypropylene fiber whose top surface (bottom surface 14) in contact with the concrete block is resistant to alkali chemical reaction such as cement material, and is vertically spaced at intervals. Alternatively, a rope 21 in which a bundle of polypropylene or polyester filaments is twisted is incorporated for reinforcement in the lateral direction.
This mat 2 has an overall average thickness of 3 mm or more, and the entire concrete pseudo-stone block per mat in this embodiment is 1.3 tons, so it can withstand this when the mat 2 is lifted during construction. Must have strength, longitudinal tensile strength is 2.94Kgf / 5cm, tensile elongation is 15% or less, and water permeability is 1 × 10 ^-2 cm / sec. did.
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). Fixed, the upper end portion A, the lower end portion B, and the left end portion C of the edge portion are provided with mat grips A, B, and C that do not have the block 1, and the right end portion D has a concrete pseudo stone. A mat joint D is provided to allow the block to extend slightly beyond the mat (see FIG. 2).

In construction, as shown in FIGS. 3 and 4, in construction such as revetment, the mats 2 with the plurality of concrete pseudo-stone blocks 1 are collectively used by a crane G as shown in FIG. 3. After loading on a transport vehicle and transporting to the site, first hold both gripping parts A and B without the blocks of the mat 2 with the gripper H provided on the crane G with the crane G, etc. 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. Note that the grip 2 moves by gripping both grips A and B of the mat 2 with a crane or the like. At this time, the mat 2 is largely curved and then returned to a flat state. The mortar 4 layer easily has a fine and narrow crack, but this crack imparts 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 between the two mats 2 is hidden behind the pseudo stone block so that it cannot be seen from the outside, and the entire revetment is uniformly covered with the pseudo stone block 1 In addition, since the non-woven mat 2 has a basis weight with a gap through which the roots of the plants can enter, the roots of the plants as well as the water pass through, and there is a customer between the pseudo stones. Combined with the accumulation of soil, plants also grow, forming a revetment that matches the natural environment as a whole.
Of course, what is necessary is just to change suitably the magnitude | size of the mat 2, the shape and magnitude | size of a holding part according to the condition of a construction site.
In this way, unlike the case of using a conventional simple shaped block, by using the mat of the present embodiment, it naturally blends in and harmonizes with the surrounding landscape, and there is no straight line in the joining line that becomes a groove, etc. Therefore, it is possible to prevent the soil from being washed away, and even if the adjacent mats are displaced (about 1.5 cm), they will not stand out.

Next, the manufacturing method of the mat | matte with a concrete pseudo stone block of a present Example is demonstrated along FIG. 5 thru | or FIG. 10, and the structure of mat | matte itself is demonstrated in detail.
As shown in the form plan view of FIG. 5, the formwork 3 for the above-described pseudo-stone block collects the individual form-forms 32 by the number of the plurality of pseudo-stone blocks 1 mounted on the mat 2 with the concrete pseudo-stone block. One large mold 3 is formed by arranging and integrating the plurality of molds 32 together.
In this rectangular mold 3, the outer frame 31 is made of FRP resin, and the pseudo stone mold 32 forming the inner pseudo stone is made of polyurethane resin, and the bottom portion 33 of the outer frame (side view of FIGS. 6 and 9). Reinforcing bars and steel plates are used to reinforce the entire formwork.
Therefore, if cement is cast in the mold 3, a plurality of concrete pseudo stone blocks corresponding to one mat can be created at a time.
As shown in FIG. 6, concrete is placed on each pseudo stone mold 32 of the mold 3, but when the bottom 14 of the shaped pseudo stone block 1 is exposed upward and the concrete is solidified. Then, a resin mortar 4 described later, which is an adhesive material, is applied to the bottom 14 with a mortar gun 5.

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 the amount is too small, a large amount of cement and vinyl acetate are consumed, and the cost is high. 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 together with sand and cement, it effectively blocks the ultraviolet ray R. However, if too much vinyl acetate is used, the cost In addition to increasing the height, it is necessary to cause cracks for water to enter and exit during transportation and enforcement work, but it is difficult for cracks to occur, 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 the ultraviolet ray R is lowered, and the function of neutralizing and blocking the alkali component is also lowered. Therefore, the amount is preferably about 15 to 40% by weight, preferably 20% by weight. It is. Although vinyl acetate may be about 60% by weight, it is expensive and wasteful, and the above-mentioned composition ratio is appropriate.
However, when the mat 2 is curved, the resin mortar 4 is cracked at the place where the bottom surface 14 (14a) of the block 1 is fixed, so the concrete between the block 1 and the block 1 exists. Since the portion not to bend is bent, cracks are 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 ray R does not reach the lower mat 2 and the blocking action of the ultraviolet ray R is not changed.
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 layer is applied to the entire surface. It is easy to form the film almost uniformly 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, it will easily crack and it will function as a water flow, but if it is thick, it will be difficult to crack, and through holes may be provided at appropriate locations on the resin mortar 4 layers with a punch 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.
The resin mortar 4 having the above composition is applied to the mold 3 (the adhesive 4 can be detached from the mold 1) and the bottom 14 of the pseudo stone block 1 with the mortar gun 5 as an adhesive material. As shown in FIGS. 6 and 7, the application method is that 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, and more specifically, when concrete is poured. The bottom surface of the block is exposed on the upper surface of the mold, and resin mortar is applied to the exposed bottom surface of the block and the upper surface 34 of the mold in between.
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, the pseudo stone block 1 and the mat 2 are bonded and fixed by the resin mortar 4 of the adhesive material, and when the curing is completed, as shown in FIG. The mat 2 with the concrete pseudo-stone block in which the mat 2 is firmly integrated is removed from the mold 3.

The non-woven mat made of synthetic resin fiber, which is the material of the mat 2, is made to be water-permeable, especially when the concrete pseudo-stone block 1 of the present embodiment is matched to a natural landscape. This is because the plant can grow and promote greening between the mats 2 on the revetment. In addition, cracks that occur in the resin mortar 4 layers due to work such as moving the mat are provided for water and air to enter and exit, but if there are few cracks, the resin mortar 4 layers between the adjacent pseudo stone blocks 2 are placed at appropriate positions. Artificial through holes may be provided by punching or the like.
As described above, the synthetic resin fiber in this embodiment is a nonwoven fabric of polypropylene fiber, and a rope 21 in which a bundle of polypropylene fibers or polyester filaments for reinforcement is twisted in the vertical or horizontal direction at intervals is incorporated. It is. Polypropylene is strong but deteriorates and becomes brittle when exposed to ultraviolet rays R.
In the mat 2 as in the embodiment of the present invention, the surface of the polypropylene fiber mat 2 is covered with the resin mortar 4 even when the mat 2 is constructed on a revetment. As shown in FIG. Even if the ultraviolet ray R (arrow in the figure) shines into the gap, the polypropylene fiber mat 2 is not directly exposed, and the resin mortar 4 covers it and is not exposed to the ultraviolet ray R of the outdoor sun. Deterioration of the resin fiber mat 2 can be prevented.
Further, when a non-woven fabric of polyester fiber and a non-woven fabric of polystyrene fiber are used as a configuration of another embodiment of the mat 2, since the resin mortar 4 is mixed with vinyl acetate, it oozes out from the concrete pseudo stone block. The alkali component is neutralized by the acid of vinyl acetate, the alkali component does not penetrate into the nonwoven fabric of polyester fiber or polystyrene fiber, and it is possible to prevent the fiber from deteriorating due to a chemical reaction with them.

Furthermore, as another example, a non-woven fabric made of a mixture of polypropylene fiber and polyester fiber, or a composite non-woven fabric in which polypropylene fiber is arranged on the upper surface side at the time of enforcement and strong polyester fiber is arranged on the lower side. Even when using, the entire surface on the upper side is covered with resin mortar 4 containing vinyl acetate, so the mat 2 is not directly exposed to sunlight, so polypropylene fibers (mat 2 material) and polypropylene Deterioration of the rope 21 twisted with filaments can be prevented, and the alkali component that oozes out from the concrete pseudo stone block can be neutralized by the acid of vinyl acetate, so that the alkali component can prevent deterioration of the polyester fiber and polystyrene fiber.
In particular, the mat with a concrete pseudo stone block of this embodiment is often applied to the outdoor sunny sunny terrain, and when the individual blocks are pseudo stone blocks, the work of arranging the individual blocks on site is Although it is troublesome, the implementation with mats with collective blocks as in this embodiment only requires that the unit mats are arranged and fixed, the work efficiency is dramatically improved, the mat is less deteriorated and the strength is long. It is maintained and durability is dramatically improved.

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 block 1a having a rectangular geometric plane as shown in FIG. Well, as shown in FIG. 12, the plurality of mold blocks 3 for concrete blocks are arranged together as a single unit so as to form an arrangement at the time of construction, and when concrete is poured. The bottom surface 14a of the block 1a is exposed on the upper surface of the mold, and a resin mortar kneaded with sand, cement, vinyl acetate, and water is applied to the exposed bottom surface 14a of the block and the upper surface 34 of the mold. A polypropylene fiber water-permeable non-woven mat 2 is laid on top to fix the block 1a to the mat, and after fixing, the block 1a is removed from the mold 3 together with the mat 2. In detail, since it is the same as the mat | matte with a concrete pseudo-stone block mentioned above, a detail is abbreviate | omitted. Of course, the geometrical plane may be a rectangular block, or a circular or polygonal block.
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.
