Description

  The present invention is a cosmetic sheet capable of dissolving the surfaces of concrete walls, concrete block walls, revetments, mortar sprayed slopes, etc. into the natural environment, and converting those wall surfaces into those effective for ecosystem conservation, and Concerning construction methods.

  As a method of decorating a concrete wall surface, a method of covering the wall surface with a sheet to which natural stone is attached has been proposed. This construction method is a makeup method that can be applied even to a wall surface having irregularities and curved surfaces.

  Patent Document 1 (Japanese Patent Application Laid-Open No. 11-170798) is such that a surface decorative material such as natural stone is attached to a flexible sheet base material, and the surface of a concrete structure is easily constructed with natural stone. Can be makeup. However, since the adhesive is applied to the entire surface of the cosmetic sheet, the adhesive is water-repellent by the adhesive, and there is no movement of water from the front surface of the cosmetic sheet to the back surface or vice versa.

For this reason, the water supplied to the stone on the surface of the sheet due to rain, etc., evaporates and drys in a relatively short time, and the surface of the sheet becomes dry. However, it is unsuitable as a place for growing plants, small animals, insects, etc., and it was difficult to cultivate the ecosystem.
JP-A-11-170798

  Therefore, the cosmetic sheet used for covering concrete walls or the like has a water retaining action so that the surface of the sheet is always kept in a wet state, and plants are grown on the surface of the cosmetic sheet.

It is a cosmetic sheet with pockets in which stone is affixed to the surface of the sheet base material with an adhesive, and it has a water retention effect on the cosmetic sheet by forming pockets on the surface of the sheet base material that can be filled with soil at appropriate intervals. Is given.
Further, by making the sheet base material of the pocket portion water permeable, water in the soil can move to the surface through the sheet, and the surface of the sheet can be maintained in a wet state.

  In addition, a water-retaining mat was installed on the back side of the sheet base material so that moisture could be retained, the sheet surface was maintained in a wet state, and moisture could be supplied to the soil in the pocket.

Since the soil filled in the pocket retains moisture such as rain, the cosmetic sheet surface is maintained in a wet state. The surface of the decorative sheet is suitable as a growth environment for moss, small animals, and plants.
The pocket can be filled with not only soil but also plant seeds, fertilizers, growth promoters, etc., so that the plant grows and the concrete wall surface is covered with natural stone and the plant covers the structure surface The artificial structure is concealed.

  In addition, by making the sheet base material of the pocket part water permeable, rainwater not only wets the soil in the pocket, but also water passes through the cosmetic sheet, so the water retaining mat on the back of the sheet base material Water is retained. Since the retained water moves from the pocket part to the sheet surface during drying, the surface of the cosmetic sheet is maintained in a moist state, and the surface of the cosmetic sheet is made an environment suitable for growing plants, small animals, insects, etc. be able to.

In summer and the like, solar heat is absorbed by the plants grown on the entire cosmetic sheet, so the ambient temperature decreases and cools.
When the finished decorative sheet is a fine stone, it can be rolled up with the stone attached, and is easy to transport and handle. When this sheet is installed on the wall surface, one end of the roll is fixed to the upper part of the wall, and the roll is developed. Since it only needs to roll on the wall using gravity, it requires less manpower and can be constructed efficiently at low cost.

  As shown in FIG. 1, the decorative sheet 1 uses a sheet base material 11 of a woven fabric made of polyester having a thickness of about 0.8 to 2.5 mm that is flexible and water-permeable.

Fix the three sides excluding the upper side by appropriate means such as adhering and sewing around the surface of the sheet base material 11 with a woven cloth of the same material as the sheet base material 11 having a width of 30 cm and a length of 20 cm. To form pockets 3. The interval between the pockets 3 is set to an interval of 5 to 30 cm and is changed according to the situation at the site.
An elastic adhesive is applied to the surfaces of the sheet base material 11 and the pockets 3 and a stone is pasted. As the stone material 2, lava having a size of 0.3 to 10 mm, 10 to 20 mm, or 20 to 30 mm or other stone materials is used. Since the inside of the pocket 3 remains the polyester sheet base material 11, it is water permeable and water can be passed from the back surface of the sheet base material 11 to the inside of the pocket. The pocket 3 is filled with clay or sand or artificial soil. If necessary, plant seeds, fertilizers, growth promoters and the like are added to the soil filled in the pockets 3, and a water retention mat 12 made of palm fibers is provided on the back surface of the sheet base 11.

  Rainwater or the like is held in the soil in the pocket, and also passes through the pocket 3 and is held on the water retention mat 12 on the back side of the sheet base material 11. The retained moisture is replenished in the pocket when the soil in the pocket is dried, so that the entire sheet including the inside of the pocket 3 is moistened, and is suitable as a growth environment for moss, small animals, and plants.

  The stone 2 is not particularly limited as long as it does not impair the landscape, but is preferably a water-permeable and porous lava. This is because lava absorbs moisture, has moisture retention, and is always easy to maintain a moist state, so that moss is likely to grow on the surface. In addition, microorganisms adhere to the pores of the lava and are effective for water purification.

  When the decorative sheet is flexible, it can be easily applied to complex shapes with irregularities, can be applied regardless of the shape of the slope, and the water retention effect on the slope is sustained. Thus, it is possible to form an environment in which animals and plants can grow well.

  The water-retaining mat 12 attached to the back side of the sheet is made of a super-absorbent resin (for example, a hydrolyzate of starch-acrylonitrile graft polymer, a hydrolyzate of cellulose-acrylonitrile graft polymer, etc.) in addition to plant palm fibers. Use water-retaining materials such as

  Other porous materials include natural stone pumice and porous artificial lightweight aggregate. The stone material 2 does not necessarily need to be porous and water-permeable, and granite, iron flat stone, serpentine and the like used as decorative materials such as concrete blocks can also be used.

  The elastic adhesive consists of a modified polysulfide polymer and a curing catalyst as disclosed in JP-A-8-60135, and the main chain disclosed in JP-A-9-188809 is hydrolyzed with polyether at the terminal. And the like comprising a polymer having a functional silyl group and iron oxide particles.

  The moss spores of the local area are mixed in advance with the surface of the stone 2 or the soil to be put into the pores or pockets 3 of the porous material so that the moss covers the surface of the cosmetic sheet 1 at an early stage. become.

  The front view of the other Example of the cosmetic sheet 1 with a pocket in FIG. 2 is shown. In this example, the pockets 3 and the regions 4 to which stones are stuck without providing the pockets 3 are alternately formed at appropriate intervals. A water-permeable joint 21 is formed between the pocket 3 and the region 4 to which the stone is attached. Water such as rainwater enters from the pocket 3 and the joint 21, makes the soil in the pocket 3 wet, and is held by a water retaining mat installed on the back of the sheet 1. The retained water evaporates from the pockets and joints during drying, and keeps the sheet 1 in a wet state.

FIG. 3 is a view in which the cosmetic sheet is installed while the upper end of the roll-shaped pocketed decorative sheet 1 is fixed to the upper part of the wall with an anchor and is expanded toward the lower part.
If the pocket 3 is filled with soil or the like, the pocket 3 may move away from the slope due to its weight. Therefore, the cosmetic sheet 1 is anchored by applying a pressing plate to the lower side of the pocket 3 so that it cannot be seen from the outside. Fix with etc.
In this figure, the water retention mat 12 is previously installed on the wall. The water retaining mat 12 to be attached to the back side of the sheet base material 11 may be attached in advance to the back side of the sheet and rolled together with the decorative sheet 1, or the water retaining mat 12 may be installed on the wall first. The installation of the decorative sheet 1 does not require much manpower, and can be efficiently constructed at low cost.
