In particular, there are many scenes in which fathers who have increased the number of holidays due to the introduction of a two-day work week have recently enjoyed playing with children with ball games such as catch ball and badminton and cycling. In recent years, many elderly people are enjoying gateball.

[0003]

However, since no on-board play equipment has been developed to play around a game board outdoors in a park or the like, an elderly person brings a go board or a shogi board to a park bench to play. There was a strong demand for outdoor game boards permanently installed in parks and the like. However, in the case of an outdoor game board in which squares are painted with paint on a wooden or stone board, a wooden board is cracked or corroded by sunlight, rain or snow, and has a problem in that it lacks durability and is difficult to use. Had a point. Further, the stone-made one has a problem that the board surface is too hard to be used as a game board, and it is difficult to restore the board when the board surface is damaged. Furthermore, although the thing made from concrete is also considered, the following is disclosed as what seems to be usable for outdoor games. That is, JP-A-49-47420 discloses a "method of producing lightweight artificial marble". JP-A-50-871

According to this configuration, the pieces can be stored in the recesses without being scattered, and the appearance around the board can be improved by decoration around the board. In addition, it is preferable to form a drain hole from the bottom surface of the recessed portion to the side surface of the outer peripheral portion of the outdoor game board because water does not accumulate in the recessed portion and the bowl and the like are not seen. Further, the decorative portion may be formed on a groove, a concave portion, or a step.
This is for enhancing the decorative effect according to the use of the game board.

[0012] In the method for producing an outdoor game board according to the present invention, 100 parts by weight of the composition for an outdoor game board is supplied with 100 to 100 parts by weight of water.
A game board material forming step of adding 5 parts by weight of water, kneading and hardening into a board shape, and a linear groove forming step of forming grid-shaped linear grooves on a smooth surface of the surface of the game board material obtained in the step, A grid forming step of filling or burying the grid material is provided in the linear groove forming step. With this configuration,
It has an effect that an outdoor game board having extremely excellent effects can be manufactured with high productivity in a simple production process.

[0013] Here, as the composition for an outdoor game board, 150 to 75 parts of fine powder aggregate are added to 100 parts by weight of cement.
It is preferable that the admixture contains 100 to 50 parts by weight of the admixture. This has the effect that the game board material has hardness and flexibility, is hard to crack, has a certain strength, has excellent impact resistance, is hardly scratched on the surface, and has excellent workability and machinability and is easy to maintain. In addition, since the grid material is buried in the linear groove, when a material that is easy to cut is used as the grid material, it can be easily cut with a plane or the like together with the board surface, and the grid can be prevented from disappearing. An outdoor game board having excellent effects can be obtained with high productivity. In addition, as fine powder aggregate, sand, stone powder,
It is composed of at least one of inorganic foam powders such as slag powder, shell powder, natural stone powder, glass powder, shirasu powder, shirasu balloon, and has an average particle size of 200 to 30 μm, preferably 170 to 50 μm. Are preferably used. As a result, since the fine powder aggregate is fine particles, it can be uniformly dispersed in the composition for an outdoor game board, and since it is uniformly dispersed with fine particles, there is no unevenness in strength, and it is cracked or chipped even when struck with a stone go stone or the like. It is possible to obtain an outdoor game board having a strength that does not need to be performed with high productivity. Further, since the fine particles are uniformly mixed, it is preferable because the hardening can be developed to the inside and the generation of minute cracks due to aging can be prevented. As the grid material in the grid material forming step, a grid material composition in which a coloring agent is added to a composition for an outdoor game board, a flexible metal such as lead, a silicone resin, or a sealant material is used. As a result, the game board material has hardness and flexibility, is hard to crack, has a certain strength, is excellent in impact resistance, is hard to be scratched, and is excellent in workability, machinability and easy maintenance for restoration. preferable. Also,
Since the grid material is buried in the linear groove, when a material that is easy to cut is used as the grid material, the grid material can be easily cut together with a board or the like to prevent the grid from disappearing.

According to a ninth aspect of the present invention, there is provided a method of manufacturing an outdoor game board according to the eighth aspect, wherein a pattern groove forming step of forming a slotted recess and / or a decorative portion on a peripheral portion of the board surface, and the decorative portion has the same color. Or a pattern forming step of filling the grid material colored in a different color. With this configuration, even when the board surface is homogenized and the maintenance work for restoring the board surface with a canner or the like is performed, the workability of the maintenance work can be improved without the canner or the like being caught.

Next, each component requirement will be described in detail. As the cement, various portland cements, blast furnace cement, fly ash cement, alumina cement, magnesia cement, silica cement and the like are used. Fine powder aggregates include sand, natural stone, slag, shells, glass,
Fine powder such as an inorganic foam is used. As the fine powder of natural stone, fine powder of limestone, marble, chalk, calcite and the like is particularly preferable. Sand is not preferred because it helps to increase the weight and if it exceeds 50% by weight in the fine powder aggregate, the weight increases.
If it is less than 20% by weight, chipping or breakage tends to occur during cutting, and the effect of increasing the amount is small. It is to be noted that fine powder generated during stone processing may be used instead of sand. Fine powder of natural stone is useful for increasing the volume and because it is a fine-grained powder,
Dense and slightly flexible with improved cutting properties.
As the fine powder of the shell, fine powder of a shell such as scallop and oyster is used. The shell may be either one washed with fresh water or one washed with seawater. The fine shell powder not only increases the volume but also makes the game board material denser, improving the hardness, flexibility and viscosity, and improving the machinability. The fine shell powder may be used as a single substance, or may be used as a mixture with another fine powder aggregate. In addition, fine powder of natural stone (ex. Marble or limestone) mainly containing calcium carbonate may be used in place of the fine powder of the shell.

As the inorganic foam, pumice stone, pearlite, foam cement waste, etc. are used in addition to shirasu and shirasu balloon. The inorganic foam contributes to weight reduction and increase in weight, and since it is a hollow fine particle, imparts flexibility and improves machinability. The inorganic foam is used by being mixed with fine powder of shells and natural stones. As the mixing ratio, the ratio of the fine particles of the shell or the natural stone to the simple substance or the mixture is preferably 0.2 to 0.1. 0.
If it exceeds 2, the hardness tends to decrease, and it tends to be unsuitable as a game board, and if it is less than 0.1, the machinability is not improved. Fine powder aggregate may be used alone, but glass,
A fine powder mixture of natural stones, shells, and inorganic foams is preferred in terms of hardness, strength, flexibility, and workability. In particular, natural stones,
A combination of a mixture of shells is preferred because it is excellent not only in hardness and strength, but also in machinability and viscosity.
The average particle size of the fine powder aggregate is 200 to 30 μm, preferably 170 to 50 μm. As the average particle size becomes larger than 170 μm, there is a tendency that the denseness and workability of the game board material decrease, which is not preferable, and as the average particle size becomes smaller than 50 μm, it becomes difficult to obtain a large amount in the market. Is also not preferred.

A pigment is used as a coloring agent used for the grid material. Particularly preferred are black pigments such as iron oxide black, red pigments with red iron oxide, blue pigments with ultramarine blue, green pigments with a chromium oxide cement colorant as a main component,
An inorganic pigment such as cherry color (manufactured by Sakae Eisei Co., Ltd.) is used. The pigment particles are fine and uniform, have excellent coloring properties, and are stable to acids, alkalis, sunlight, wind and rain, and have excellent durability without discoloration or fading. The compounding amount may be 30 to 10 parts by weight with respect to 100 parts by weight of cement according to the degree of coloring, and the compounding amount of fine powder aggregate (fine powder such as shells and natural stones) may be reduced in proportion to the amount of coloring agent added. .

The composition of the composition for an outdoor game board is 150 to 75 parts by weight, preferably 130 to 80 parts by weight, of fine powder aggregate per 100 parts by weight of cement. 13
When the amount exceeds 0 parts by weight, chipping or the like is likely to occur, and the mechanical strength tends to be lacking. When the amount is less than 80 parts by weight, the hardness increases, cutting becomes difficult, and restoration tends to become difficult. 130 to 80 parts by weight is particularly preferable because it has a moderate flexibility and is light and easy to cut. Examples of admixtures include mortar adhesive and mortar waterproofing quick setting agent.
100 to 50 parts by weight of a species or a mixture of two or more species is suitably used. Mortac Petlock (made by Asahi Kasei Corp.) such as vinyl acetate, acrylic or synthetic rubber-based synthetic resin emulsion for cement admixture, and Ibi High Bond (made by Ibiken Corp.) ), Sika Top Emulsion (manufactured by Nippon Sika Co., Ltd.), Hitech Liquid (manufactured by Chemics Co., Ltd.), and the like, and coating, kneading, and mixing types are used. When the amount of the admixture exceeds 100 parts by weight with respect to 100 parts by weight of the cement, depending on the type of cement, peeling tends to occur at the time of demolding during production, and when less than 50 parts by weight, cutting dust tends to be generated during maintenance. Was observed. Since the mortar adhesive makes the structure of the outdoor game board dense and has adhesiveness and water repellency, it is easy to cut and produce, and is particularly preferable for those which are installed outdoors. In addition, since the shrinkage rate is reduced and cracks are less likely to occur, it is particularly preferable for those to be displayed outdoors. Also, a mortar waterproofing quick setting agent is desirable because it tends to improve the structure and improve the impact strength.

The width of the linear groove for filling or burying the grid material is 10 to 1.5 depending on the size of the outdoor game board.
mm, preferably 7 to 2 mm. Also,
A depth of about 10 mm from the surface of the game board material is used. Thereby, when the board surface of the game board is damaged, the surface can be shaved and restored any number of times, which is preferable.
As the anchor portion, at least one or more anchor bolts are provided depending on the size of the outdoor game board.
This is because the user does not move the outdoor game board without permission.
