Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an aerated concrete board containing plant seeds that is used for soundproof walls on expressways, balconies of houses, etc.

[Conventional technology]

Aerated concrete boards are made by mixing finely pulverized silica sand and lime or cement, adding water, foaming agents, special chemicals, etc. to form the foam, and then curing it naturally.It has a porous structure, so it has a sound-absorbing effect. It has been used for soundproofing walls on expressways, etc.

[Problem that the invention attempts to solve]

However, if expressways are surrounded by soundproof walls made of aerated concrete plates, the scenery will become desolate and there is a risk that the mental state of drivers will deteriorate.

[Means for solving problems]

As a means to solve the above conventional problems, the present invention provides a cellular concrete board 1 containing plant seeds, in which plant fibers 3 as a seed bed and plant seeds 4 are uniformly dispersed in a concrete matrix having a large number of pores 2. This is what we provide.

〔Example〕

To explain the present invention with reference to an embodiment shown in the figure, a large number of pores 2 are formed in the concrete matrix of the aerated concrete board 1, and fibers 3 as a seed bed and plant seeds 4 are uniformly distributed. is mixed with.

The aerated concrete board 1 is made by finely pulverizing and mixing silicic acid-containing materials such as crushed stone, silica sand, and fly ash, and calcium-containing materials such as quicklime and cement, and adding water, foaming agents, special chemicals, etc. It is manufactured by further mixing fibers 3 and plant seeds 4 as a seed bed to the aerated concrete composition and foam-molding the mixture. As the above-mentioned fibers, vegetable fibers such as coconut fibers, cotton fibers, and hemp fibers are used, but a mixture of various fibers such as synthetic fibers such as polyester fibers and polyamide fibers, or recycled fibers thereof may also be used. As the plant seeds, seeds of grasses commonly used for covering soil, such as grass, sweeping grass, and ivy, are mainly used, but seeds of other flowering plants may of course be used. In addition to the above composition, other components such as a water-absorbing polymer, fertilizer, straw, and rice grain may be added.

The cellular concrete board 1 may have various shapes other than a flat plate. For example, in the example shown in FIG. 3, a circular recess 1A is provided on the surface of a multi-cellular concrete board 1, and in the example shown in FIG. 4, a stepped portion 1B is provided on the surface of a multi-cellular concrete board 1. be. In this way, by providing an upwardly curved surface, an upwardly inclined surface, a horizontal surface, etc. on the surface of the aerated concrete board 1, the sunlight irradiation rate, moisture supply rate, etc. of this surface are improved, and this has a favorable influence on the growth of plants. Further, as shown in FIG. 5, the aerated concrete board 1 may be shaped like a fence when applied to a balcony or the like, or it may be shaped into various shapes such as an octagon, a face cut shape, a cross shape, etc. as shown in FIG. A large number of block-shaped cellular concrete plates 1 may be laid using these blocks.

[Effect]

In the aerated concrete board 1 of the present invention, plant fibers 3 and plant seeds 4 are uniformly dispersed in a concrete matrix in which fine pores are uniformly distributed, and are retained without peeling off during storage and transportation. is placed under low temperature to control the germination of plant seeds 4. If the aerated concrete board 1 is placed in the outside world at the site, kept at room temperature, and supplied with moisture by sprinkling water, etc., the aerated concrete board 1 is uniformly porous, so it absorbs water uniformly, and the plant seeds 4 become as shown in Figure 2. As shown, plants 5 germinate uniformly and grow from one side of the aerated concrete board. The plant fibers 3 serve as a seed bed to improve the adhesion of the plant seeds 4 to the aerated concrete board 1, absorb moisture in the aerated concrete board 1, swell, retain the moisture, and prevent corrosion over time. Furthermore, it swells easily, exhibits a high degree of water retention, and acts as a fertilizer by itself. Furthermore, in addition to the role of the seed bed, the vegetable fibers 3 also have a reinforcing effect on the aerated concrete board 1.
When aerated concrete plates 1 are connected to each other to form a soundproof wall or the like, a female cone 6 and a male cone 7 are formed on the joint surfaces at both ends.

[Effect of idea]

Because the present invention has the above-mentioned structural effects, it is possible to obtain a lightweight, strong aerated concrete panel, and the plant fibers and seeds do not peel off during storage or transportation, and the plant seeds inside the aerated concrete panel germinate and grow smoothly, so that the surface of the aerated concrete panel is covered with plants. If such strong aerated concrete panels are used as soundproofing walls on expressways, the expressway will be surrounded by greenery, improving the mental state of drivers. In addition, the air contained in the aerated concrete panel, plant fibers, and plants will provide extremely high sound absorption properties. In apartments, it is not possible to lay soil on the balconies, which tends to result in a lack of greenery, but if the aerated concrete panels of this invention are used on the balconies, it will be possible to green the balcony surface without using soil.
