BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a net used for directly attaching a tile to a wall surface of a concrete or the like, a net-attached tile, and a method of manufacturing the same.

[0002]

2. Description of the Related Art Mortar is used as an adhesive for building exterior walls.
A 30cm square net is attached to the back of the tile to improve workability and prevent peeling. The soles of the tiles are high so that they do not bite into the mortar and peel off. On the other hand, the inner wall of the tunnel is tiled with an epoxy-based adhesive, and a tile holding plate method or a sudare method is employed in terms of construction efficiency. In the tile holding plate method, the tiles are arranged so that the back of the tile is exposed on the holding plate, and the tiles are stretched by pressing against the skeleton coated with the adhesive. This method is described in, for example,
Although this method is proposed in Japanese Unexamined Patent Publication No. 749, the tile tends to shift up, down, left, and right. On the other hand, the Sudare method is proposed, for example, in Japanese Utility Model Laid-Open No. 55-129941, in which tiles are connected by two or more codes in the tile arrangement direction, and the tiles are connected only in one row. And the efficiency of construction was limited.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described. First, the tile directing net of the present invention, as described above, on the back of a plurality of arranged tiles, hanging the net-attached tile with the net attached at the time of construction, stretched to the frame, by the weight of the tile itself The elongation of the net is most important. This elongation is, of course, largest between the uppermost tile and the second tile, and gradually decreases toward the bottom. Then, the expansion between the tiles is accumulated, and the displacement of the tile located at the lowermost stage becomes a problem. In any case, if the expansion of the net itself is large, the distance between the joints of the tiles naturally becomes uneven, which is not preferable from the viewpoint of construction and appearance. Therefore, the elongation of one unit with a net attached to a tile, that is, the ratio of the elongation when suspended to the overall dimensions when the net is left standing on a flat surface is 0.3%.
It must be: For example, if one unit has a standing length of 700 mm, the elongation must be 2.1 mm or less.
If it is 0.3% or less, the external dimensions of the individual tiles vary, so that the tiles are offset and irregularities in the joints become inconspicuous.
A more preferred range of elongation is 0 to 0.2%.

In order to reduce the elongation of the net, it is particularly important to use a filament yarn.
When spun yarn is used, it tends to be stretched because it has many twists.
It is better that the twist is small even with a filament yarn. As the material, for example, nylon, polyester, vinylon, acryl, polypropylene, aramid and the like can be used. The fineness of the filament of the net yarn is preferably in the range of 1,000 to 5,000 denier. If it is less than 1,000 denier, it cannot bear the weight of the tile and may be stretched or cut.
On the other hand, if the thickness becomes 5,000 denier or more, the cross section of the net yarn becomes round and hard, and the adhesiveness to the tile decreases.
A more preferred range is from 1,800 to 4,000 denier.

The shape of the mesh of the net is not particularly limited, such as a lattice shape, a turtle shape, and a rhombus shape. However, a lattice shape is preferred from the viewpoint of small elongation and adhesive workability. When the lattice shape is adopted, the size of the first eye must be in the range of 10 to 30 mm when the distance between the centers of the net yarns is measured. In this case, if the thickness is less than 10 mm, the film is formed on the net when the adhesive is applied by dip, and the adhesiveness between the frame and the tiles is reduced. When the size of the eyes exceeds 30 mm, the contact portion between the net and the tile is reduced, and the tile is easily peeled off from the net. In general, the finer the yarn, the smaller the net, and the larger the yarn, the larger the net. The shape of the net is preferably square, but may be somewhat rectangular. Also, the smaller the tile size,
Use a net with fine threads and small eyes.

Further, the tile directing net of the present invention preferably has a lattice shape in which warp yarns and weft yarns intersect. Further, it is preferable that the warp direction yarn is longer than the weft direction yarn and that the warp direction is up and down during construction.

In the method of attaching a net to the arranged tiles, a warp-direction thread is arranged vertically so that the net does not stretch when suspended during construction, and then attached to the tile. It is preferable that the yarn in the weft direction also intersects with the yarn in the warp direction in order to keep the space between the warp joints constant.

The net is preferably a Russell knit.
With this weaving method, it is possible to freely design and manufacture the yarn thickness of the net or the size of the net. With woven fabric, the eyes are easily displaced and large eyes cannot be formed. The twisted structure has a lot of twists and is easily stretched, and the productivity is low. Frogs and knitting or knotless knitting are not preferred because they are often twisted and the knitted fabric is twisted and lacks stability. Further, it is preferable that the warp yarn is thicker than the weft yarn. This is because the warp-direction yarn weighs only the arranged tiles, so that it is better to have a large thickness in order to have strength and suppress elongation. On the other hand, the yarn in the weft direction may be thinner than the warp yarn, as long as it is only necessary to keep the distance between adjacent tiles constant. The ratio of the thickness of the warp to the weft is preferably about 9: 1 to 2: 1. If the ratio is further increased, the balance as a net is lost, which is not preferable.

Preferably, the warp-direction yarn contains an insertion yarn. The insertion yarn referred to herein is a yarn that does not form a loop, and is, for example, a monofilament yarn or a multifilament yarn. When the insertion yarn is included, no loop is formed in the yarn in the longitudinal direction, which is effective in suppressing elongation. The material and thickness of the knitting yarn can be changed. For example, a knitting yarn can be freely combined with a nylon yarn, and an insertion yarn can be made with a polyester yarn.

It is preferable that the tile directing net has a resin processed on the net. This resin processing prevents stitches from shifting and improves workability when bonding to the arranged tiles. Although the resin is not particularly limited, for example, acrylic resin, melamine resin and the like can be preferably used. The hardness of the net after resin processing is preferably medium, and if it is too hard, the adhesion to the tiles is reduced.

In the tile with a net according to the present invention, a plurality of tiles having no soles or a sole height of 0.5 mm or less are arranged at least two rows in the longitudinal direction at a predetermined interval. The tile is attached to the above-described net with a synthetic adhesive on the back surface of the tile. Since the net is attached to the back of the tile in this way, the tile must have no back foot or the back foot height should be 0.5 mm or less. The tile has a small amount of adhesive and can be easily and reliably bonded.
The size of the tile is not limited, for example, 45
Two, 45 three, two hooks and two sides 100 × 200mm
Etc. tiles can be used. When using relatively large tiles, two rows are used, and when using small tiles such as 45 two-rows and 45 three-rows, three or four rows are used to facilitate construction. The adhesive between the tile and the net is preferably water-based because it is easy to handle. For example, there are ethylene vinyl acetate, polyacryl, polyurethane and the like.

The size of the tile with a net is 20 to 70 in width.
It is particularly preferred that the length be in the range of 50-100 cm in the range of cm.

From the viewpoint of construction efficiency, at least two rows of tiles are required. If two rows of 45 tiles are used, the size of the tile with a net is about 20 cm. Also,
If two tiles are attached in three rows, the size of the tile with a net is about 70 cm in width. If the width is less than 20 cm, the construction efficiency decreases, and if the width is 70 cm or more, construction may be difficult. Further, the length of the tile with a net is preferably in the range of 50 to 100 cm. If it is less than 50 cm, the construction efficiency may be reduced, and if it is 100 cm or more, construction may be difficult.

The net with tiles described above can be manufactured as follows. That is, a first step of arranging a plurality of tiles at predetermined intervals with their backs facing up, a second step of applying an adhesive to the nets, and a step of placing a net on the backs of the arranged tile rows and applying soft pressure. It is characterized in that four steps of three steps and a fourth step of drying the tile with a net are performed in this order.

The first step is a step of fitting the tiles with the back surface of the tiles up in a formwork such as a wooden board called an arrangement plate in which a predetermined joint interval is set. An array plate in which the size, number of tiles, and joint intervals are set is used. The size of the arrangement plate is approximately the size of a tile with a net. The material of the array plate is preferably made of synthetic resin other than wood.

The second step is a step of applying an adhesive to the net. A water-based adhesive is preferably applied to the net cut to a predetermined size. As the adhesive, vinyl acetate, polyacryl, polyurethane or the like can be used. Examples of the coating method include a dipping method and a transfer method using a roll coater. It is preferable to apply it on the front and back of the net from the viewpoint of stability.

The third step is a step of placing a net coated with an adhesive on the back surface of the arranged tiles and applying soft pressure. By applying soft pressure from the top of the net, the adhesion between the net and the tile is increased, and the net can be more firmly bonded. As for the soft pressure, when a release paper or a release plate made of Teflon or the like is used, the net coated with the adhesive is easily separated and adheres only to the tile side. The degree of the soft pressure is preferably such that the yarn of the net becomes slightly flat.

The fourth step is a step of drying continuously. It is put together with the array plate into a continuous dryer, and is continuously dried to be solidified. The continuous dryer preferably has a total length of about 10 to 15 m and a speed of about 1 m / min. The ambient temperature is preferably about 80 to 90 ° C. When the continuous dryer comes out, it is allowed to cool naturally and the net-attached tile is taken out of the array plate.
