Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seed stone exposing method for decorating the surface or wall of various structures with a decorative stone such as natural stone.

[0002]

2. Description of the Related Art Seedstone exposure method is a method of exposing various kinds of decorative stones such as natural stones and artificial stones on the surface of various structures. There are two methods: a method of constructing a product with an exposed seed stone on site.

[0003] Conventionally, in-situ casting method of concrete surface decoration has been widely used. An embedding method in which mortar is uniformly poured on existing concrete and seed stones are embedded one by one, and seed stones are kneaded into mortar. There is a washing method in which seed concrete is exposed on the surface of concrete by, for example, pouring concrete onto existing concrete, and washing off the mortar of a surface layer before the concrete hardens.

Further, in order to easily and uniformly perform a cast-in-place method, a mat for exposing a seed stone to a net and fixing the seed stone with an adhesive has been proposed (JP-A-64-3335).
No. 4). It is expected that the use of the seedstone exposure finishing mat allows the seedstone to be easily exposed on the surface of the structure as compared with the embedding method, the washing method, and the like.

[0005]

However, the embedding method is limited to only seeds having a large grain size due to limitations in workability, and is applied to seeds having a small grain size, for example, seeds having a size of five or less. It is difficult.

Further, in the washing method, it is difficult to consume an unnecessarily large amount of expensive seed stones, it is necessary to treat the washed sewage, and it is difficult to give a natural feeling of unevenness to the exposed surface of the seed stones. That the joints are difficult to finish,
There is a problem that construction of a vertical surface such as a wall surface is extremely difficult.

[0007] Also, the seed stone exposure finishing mat is manufactured by bonding the seed stone and the net with an adhesive so as not to fall off, and the configuration of the seed stone exposure finishing mat has been proposed. There is no commercially available product, and therefore, there is no construction example of a seed stone exposed finish using the product. JP-A-64-33354 discloses that a seedstone exposed finishing mat can be constructed by laying it on uncured concrete or mortar and pressing it. Pressing the stone against concrete or mortar is not enough to fix the seed stone. In other words, a mat for exposing a seed stone is pressed against concrete or mortar before curing,
If concrete or mortar is hardened in that state, the sticking of the slag will hinder the firm fixation of the seed stone.

[0008] There is a great demand to easily perform a seed stone excavation method on the wall surface of a new or existing building at the site, but at present there is a need for a technical breakthrough.

The present invention has been made in order to solve the above-mentioned problems, and has excellent fixability to the surface of a seed stone substrate.
Further, it is an object of the present invention to provide a seed stone exposure method that can be applied to a vertical surface and can also be applied to an existing structure, and a seed stone exposure method in which an exposed surface of a seed stone can exhibit a natural unevenness. .

[0010]

In order to achieve this object, in the present invention, the seed stone is placed on one surface of a net having a mesh size smaller than the grain size of the seed stone so that the mounting surface of the net is flat. In the seedstone exposure method using a seedstone-mounted mesh sheet fixed with an adhesive, a step of applying a seedstone fixing adhesive to the surface of the foundation for construction to a uniform thickness,
The seed stone-mounted mesh sheet is used for fixing the seed stone so that the adhesive for fixing the seed stone completely oozes between the seed stones and completely covers the net and covers a part of the seed stone fixed to the net. And press-fitting the adhesive.

In this case, one or both of the step of removing the excess seed stone fixing adhesive oozing out between the seed stones and the step of providing a joint filling material at the joint part are performed.

In these cases, the seed stone fixing adhesive is a polymer cement type adhesive.

The seed stone fixing adhesive is an organic adhesive.

Further, the seed stone having a plurality of sizes is used.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A seed stone exposing method according to the present invention will be described. First, as shown in FIGS. 2 and 3, glass fiber, carbon fiber, aramid fiber, polyester fiber,
One or two or more types of nets 1 composed of fibers selected from vinylon fibers, nylon fibers, and polypropylene fibers, and a net 1 having a mesh size smaller than the grain size of the seed stone 2 has a plurality of sizes. The seed stones 2 having various shapes are fixed with an adhesive so that the mounting surface becomes flat, and the seed stone mounting mesh sheet 11 is manufactured. In this case, as the seed stone 2 to be fixed, natural stone is suitable for exhibiting natural beauty, but is not necessarily limited to this, and can be selected from many types such as ceramics and various pseudo natural stones. Next, as shown in FIG. 1A, a seed stone fixing adhesive 4 is applied to the surface of the foundation 3 such as a vertical concrete plate to a uniform thickness. In this case, the seed stone fixing adhesive 4
Examples of such adhesives are polymer cement adhesives that add ethylene / vinyl acetate, acrylic resin, styrene / butadiene rubber, chloroprene rubber, natural rubber, etc. to accelerated cement, and organic adhesives such as epoxy resin, polyester resin, and methacrylic resin. And the like can be selected in consideration of the material of the base 3 and the like. Next, as shown in FIG. 1 (b), the seed sheet mounting mesh sheet 11 is attached to the seed stone fixing adhesive 4 and pressed in using a roller 5 or the like, or pressed in manually to fix the seed stone. The adhesive 4 for use exudes between the seed stones 2 to completely cover the net 1 and cover a part of the seed stone 2 fixed to the net 1. Next, as shown in FIG. 1 (c), the excess seed stone fixing adhesive 4 oozing out between the seed stones 2 is scraped off using a brush 6, etc. The exposed surface of the seed stone 2 is cleaned and finished. Next, as shown in FIG. 1D, in order to enhance the design of the exposed surface of the seed stone 2,
A joint filling material 7 such as colored cement is provided at the joint to perform a joint filling finish.

In this seed stone exposure method, the seed stone 2 is fixed together with the net 1 using the seed stone fixing adhesive 4.
The seed stone 2 can be firmly fixed on the surface of the base 3.
When the seed 1 is fixed together with the net 1 using the seed stone fixing adhesive 4 made of a polymer cement adhesive or an organic structural adhesive, the seed 2 is particularly firmly fixed to the surface of the base 3. can do. Also, since the seed stones 2 having a plurality of sizes are bonded to the net 1 so that the fixing surface is flat, the surfaces of the seed stones 2 that are in contact with the net 1 are flat with each other, but are opposite to each other. Indicates unevenness close to nature when seed stone 2 is scattered. Therefore, in the seed stone exposed structure manufactured using such a seed stone mounting mesh sheet 11, the exposed surface of the seed stone 2 can have a natural unevenness. On the other hand, the surface of the seed stone 2 on the ground 3 side is the net 1
Therefore, the exposed surface uniformly contacts the surface of the base 3 while maintaining the natural unevenness, and all the seed stones 2 are firmly fixed to the surface of the base 3. Also, in the conventional washing method, it is difficult to hold a thick mortar layer and a large-sized seed stone on a vertical surface, and thus, application to the vertical surface is limited to a small-sized seed stone. The seed stone exposing method using the stone-mounted mesh sheet 11 overcomes these difficulties and can be easily applied not only to a horizontal plane but also to a vertical plane. Further, in the repair of the wall surface of the existing structure, it is necessary that the thickness of the repair layer be as thin as possible. However, if the seed sheet-mounted mesh sheet 11 is used, the net 1 may contact the ground 3. By fixing the seed stone to the seed stone fixing adhesive 4, it is possible to apply the seed stone 2 to a thickness almost equal to the thickness of the seed stone 2, so that the present invention can be applied to an existing structure. Further, after the seed stone 2 is fixed to the base 3 together with the net 1, it is easy to finish the joint portion with an arbitrary joint filling material 7. In this case, the joint portion is finished using colored mortar or the like. Is performed, it is possible to obtain a highly designable structure in which the seed stone 2 is exposed on a background of a desired color. Also,
Since the seed stone 2 can be fixed to the base 3 together with the net 1 with a special seed stone fixing adhesive material 4 such as a polymer cement adhesive or an organic structural adhesive, the seed stone mounting mesh sheet 11 is applied. The foundation 3 that can be used for the seed stone exposure method is mortar finish surface, concrete direct surface, PC
Examples include board, slate, ALC, plywood, gypsum board, and many other types. Therefore, the seed stone exposure method according to the present invention is applicable to a wide range of seed stone exposure.
