Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is shipped from a factory as a finished product and is used as a building exterior material.
The present invention relates to a tile panel in which a tile and a base plate are integrally combined and a method for manufacturing the tile panel.

[0002]

2. Description of the Related Art This type of tile panel is effective in shortening the construction period because it does not require on-site construction of tiles, and the base plate is excellent in fireproofing, fireproofing, sound insulation and heat insulation. Used as an exterior wall material for fireproof construction.

For example, the conventional one is, for example, Shokai 58-13452.
Tile panels proposed in Publication No. 7 and actual fair 2-11
Although there are architectural composite materials proposed in Japanese Patent No. 534, both have advantages and disadvantages, and there are structural problems.

In the former tile panel, as shown in FIG. 14 (A), a groove 52 having a narrower opening than the bottom is formed in the tile attaching surface 51 of the panel 50 having a hollow portion. 50
The tile 53 is drilled from one side edge to the opposite side edge.
On the back surface, a ridge 54 which is narrower on the root side than on the top is bored from one side edge of the tile to the opposite side edge, and the ridge 54 is embedded in the groove 52 so as to be embedded. Since it is a fired product, the fitting play space between the groove and the ridge due to the molding dimension error of the tile which is unavoidable is filled with the adhesive 55, and the ridge is buried in the groove. It is one.

However, since an adhesive such as mortar is used, the productivity is low and the productivity is low. Furthermore, due to the fitting play between the two, the tiles are tilted in the vertical and horizontal directions, and the appearance is poor. There is a problem such as the appearance of the. On the other hand, in the latter case, as shown in FIG. 14B, the engaging portion 61 is formed on the surface of the cement plate 60 having a hollow portion.
And a small tile 62 having an engaged portion 63 to be fitted to the engaging portion 61 formed on the back surface is fixed, and has the following problems similar to the former one. .

That is, since the tile is a pottery, it cannot be obtained with the same precision as that of a metal processed part.
Incidentally, the tiles used for the interior and exterior of the building have fundamentally different molding precision standards from the ceramics which have been used for machine parts and the like in recent years, in terms of the purpose of use and cost. Therefore, there is a problem that the fitted state of the engaged portion and the engaged portion cannot be obtained, and in reality, play for fitting is essential, and the rattling of the tile due to this play is suppressed with an adhesive. In the end, as with the former one, there are problems with productivity and appearance.

Further, in Japanese Patent Laid-Open No. 59-173454, FIG.
As shown in (C), a wall finishing structure having a structure in which a support 71 is fixed to a wall base 70, and a tile 72 having a cutout 73 engaged and fixed to the support 71 is fixed However, as with the former two, there are productivity and appearance problems.

The applicant proposed a tile panel of Japanese Patent Application No. 3-211066 as a solution to these drawbacks of conventional products.

The structure of this tile panel is shown in FIG.
As shown in, a plurality of vertically engaging engagement projections 81 are formed on the back side of the tile 80, and the engagement projections are provided on the front side of the base plate 82.
In a tile panel formed with an engaging recess 83 that engages corresponding to 81, a lower portion 81a of the engaging protrusion 81 of the tile 80.
Is formed in a hook shape in a downward cross section with respect to the base plate 82, and an upper portion 83a of the engaging recess 83 of the base plate 82 is formed in a hook shape in an upward cross section with respect to the tile 80. A fixture 85 is interposed in a space portion 84 formed by a facing surface between the side engagement convex portion 81 and the upper engagement concave portion 83 of the base plate 82, and the fixture is provided.
The tile 80 is fixed to the base plate 82 by 85.

This tile panel is a completely dry type panel and has an excellent effect that it is easy to manufacture because it does not need to be cured by adhesion or the like, and furthermore, the appearance of the tile assembling is not disturbed. It is beautiful without it, but it still has the following problems.

Since the adjustment of the assembling precision by the tile and the base plate depends on the elasticity of the fixing tool, the tile mounting work must be performed for each tile, which is an unfavorable structural and manufacturing problem. It had been. That is, the engagement relationship between the tiles and the base plate requires a gap for creating a space, and if all the tiles are engaged with the base plate, each tile between the left and right adjacent tiles and the base plate is assumed. Even if you try to insert the fixture at once in the space, the tiles in the non-inserted part will shift by the gap due to the impact vibration that accompanies the insertion, and the space cannot be maintained stably, so you can insert it all at once. However, after all, the tiles and the base plate must be combined for each individual tile, and it is extremely difficult to combine a plurality of tiles at once.

In order to secure a space, the lower portion of the engaging projection of the tile is formed in a hook shape in a downward cross section, and the upper portion of the engaging recess of the base plate is formed in a hook shape in an upward cross section. However, it is known that the tile having such a peculiar shape has large distortion deformation in proportion to the degree of the irregular shape, and the gap between the base plate and each tile, that is, the space portion size further varies. As a result, the assembling accuracy must be adjusted more and more due to the elasticity of the fixture, and the dimension of each space is not stable, which makes it more difficult to combine a plurality of tiles at once.

Further, as a common problem of the above-mentioned wet type and dry type, since the connecting element of the tile and the base plate is formed in the overlapping portion of both and is separated from the tile surface portion, the space between the tile surfaces is increased. Undesirable unevenness is likely to occur, and it is difficult to control the unevenness of the panel surface. For example, it is difficult to obtain a panel surface having no unevenness in a tile of a pottery which cannot avoid distortion during molding.

[0014]

The problem to be solved is that the assembly of the base plate and the tile cannot be combined and fixed with higher strength than the case of using the elastic fixture while utilizing the advantage of the dry panel. You can freely select the points and the combination work of the base plate and tile by efficiently assembling a plurality of tiles with each tile temporarily fixed to the base plate or by assembling each tile. However, it is difficult to control the unevenness of the panel surface, and it is difficult to obtain a panel surface without unevenness.

[0015]

In the tile panel of the present invention, in order to achieve the above-mentioned object, an engaging recess is formed on the back surface side of the tile, and the engaging recess is provided on the front surface side of the base plate. In a tile panel formed with engaging protrusions that engage with each other, a substantially parallel inclined surface that inclines upward and outward in the engaging protrusions of the base plate, and inward downward in the engaging recesses of the tile. In the engaged state of the tile and the base plate, a groove portion serving as a fixing space portion is formed at the upper and lower end portions of the tiles vertically adjacent to each other, and the same groove is formed in the fixing space portion. It is characterized in that the tile and the base plate are joined by inserting a fixture having substantially the same cross-sectional shape as the space.

Further, in the present invention, the fixing space portion has a substantially circular cross-sectional shape, and the fixing tool has a cross-sectional shape in which the major axis direction is slightly larger than the diameter of the space portion and the minor axis direction is. It is characterized in that it is formed in an elliptical shape slightly smaller than the diameter of the space.

Further, according to the present invention, the fixture is formed to be slightly larger than the sectional shape of the fixing space, and a large number of lines having a substantially triangular cross section are formed along the longitudinal direction on the outer peripheral surface. And The cross-sectional dimension ratio between the fixture and the space is preferably slightly larger than that of the fixture, specifically about 0.5 mm. When the fixture has a round bar shape, the streaks may be linear or spiral along the longitudinal direction.

Further, according to the present invention, the fixture is characterized in that a tapered insertion guide portion is formed at an end portion on the insertion side, and the length thereof is set to a fixed length substantially equal to the length of the tile.

In the present invention, the inclined surface of the engaging convex portion of the base plate is upward from the horizontal, the inclined surface of the engaging concave portion of the tile is downward from the horizontal, and the inclination angles are the same. Then, between the upper and lower engaging projections of the base plate, the upper end of the lower tile and the lower end of the upper tile are positioned vertically adjacent to each other, and when the fixture is inserted, the engaging Relationships are close to each other.

Notches may be formed in the engaging projections of the base plate in the present invention in appropriate intervals. In this case, water that has entered from the tile gap flows down through the notches. Effective for draining and drying.

Further, the tile in the present invention is appropriately selected from known members typified by ceramics. The base plate is a ceramic-based member such as a concrete plate, and a typical example is a hollow extruded panel. A metal material is mainly used for the fixture, but a hard synthetic resin material may be used. The fixing tool is inserted by appropriate factory equipment such as a hydraulic cylinder, but it can also be inserted by light impact with a small hammer or the like.

Further, the dimensional accuracy of the engaging concave and convex portions of the ceramic tile and the ceramic base plate is about ± 0.5 to 1.0 mm, so that the engaging concave portion of the tile and the engaging convex portion of the base plate are fitted together. The fitting accuracy (gap) is about ± 1.0 to 2.0 mm at maximum. Then, the dimensional accuracy of the fixing space portion composed of the opposed groove portions is naturally set to the plus side. The cross-sectional shapes of the fixture and the space may be circular, elliptical, triangular, quadrangular, hexagonal, or any other shape similar thereto, and are appropriately selected.

In the method of manufacturing a tile panel of the present invention, the back surface of the tile is applied to the front surface of the base plate from the facing direction, and the engagement concave portion on the front surface side of the base plate is engaged with the engagement concave portion on the rear surface side of each tile. After temporarily fixing by doing, with respect to the fixing space formed by both groove portions in the upper and lower ends of the tiles vertically adjacent to each other, skewered or space portions individually over each continuous hole-shaped space portion, It is characterized in that the base plate and the tiles are combined and assembled by inserting a fixing tool having substantially the same cross-sectional shape as the same space portion.

[0024]

[Function] The tile back surface is applied diagonally from the upper side in the facing direction to the surface of the base plate that has been erected vertically or slanted or laid horizontally. Engage and temporarily fix the required number of tiles on the surface of the base plate to cover the entire surface. In this temporarily fixed state, the fixing spaces formed by the pair of grooves at the upper and lower ends of the tiles vertically adjacent to each other do not cause the movement of the tiles even by the impact vibration accompanying the insertion of the fixture. Therefore, in order to stably maintain the space parts, for all these space parts, insert the fixing tool at a stretch over each space part continuous in the row, while connecting the tiles to the upper and lower end parts. Keeping engaged, all tiles can be efficiently bonded to the base plate at the same time.

In the assembled state of the tile and the base plate, the fixture is in the space and engages with both grooves in the upper and lower ends of the upper and lower tiles in a wedge shape so that the upper and lower ends of the tile are joined. To prevent the tiles from slipping in the front-back direction, and the engaging recesses from the engaging projections to prevent the tiles from slipping out in the direction of inclination with a fixture at the lower end of the tile above the tiles. As a result, the engaging concave portion is joined to the engaging concave portion with high strength in the engaged state, and the joined state is maintained unless the fixture is sheared into upper and lower halves. As a result, the upper and lower connection points of the tile at the upper and lower ends of the tile and the engagement concave and engagement convex portions on the rear side between the upper and lower connection points are broken until the tile or the base plate is broken. The joints may be located at the corners of the triangle to maintain strong bond strength by acting as fixed points that restrain each other's movement.

Further, in the assembled state of the tile and the base plate, since the upper and lower ends of the side of the tile surface are connected and fixed by a fixture, there is no step between the surfaces of the tiles, and there is little or no unevenness in the panel. You can get a face.

Assembling condition of the tile and the base plate is as follows.
The fixing space has a substantially circular cross section, and the fixing tool has an elliptical cross section whose major axis direction is slightly larger than the diameter of the space part and whose minor axis direction is slightly smaller than the diameter of the space part. In that case, by rotating the fixing device at the entrance of the space and driving by selecting an appropriate shaft angle at which the fixing device can be driven and high strength is obtained, the dimensional error of the space is absorbed, A strong bond state is obtained.

The assembling condition of the tile and the base plate is as follows.
If the fixture is slightly larger than the cross-sectional dimension of the space and a number of lines with a substantially triangular cross section are formed along the longitudinal direction on the outer peripheral surface, the space without increasing the hammering resistance of the fixture. A high bond strength is obtained by absorbing the dimensional error of the part. In addition, even if the streak tips of the fixture partly cut the tile or the base plate at the time of driving, the cutting powder is contained in the groove portions of the streaks, so that the high bonding strength can be maintained.

Assembling condition of the tile and the base plate is as follows.
If the fixture has a tapered insertion guide at the end of the insertion side and the length is approximately equal to the length of the tile, use appropriate continuous insertion means such as bullets and magazines of firearms. For example, maintenance of the tile can be easily performed when the assembly space is reduced at the time of factory manufacturing and when a part of the panel surface is damaged due to a disaster after construction. Further, it is also effective in the case where tiles can be individually bonded to the base plate to manufacture a panel having a special shape such as around windows.

Claims (5)

[Claims] 1. A tile panel comprising: an engaging concave portion formed on the back surface side of a tile; and an engaging convex portion engaging corresponding to the engaging concave portion on the front surface side of a base plate. The engaging convex portion of the base plate is formed with a substantially parallel vertical inclined surface that is inclined upward and outward, and the engaging concave portion of the tile is formed with a substantially parallel vertical inclined surface that is inclined downward and inward. In the combined state, grooves are formed in the upper and lower ends of the tiles that are vertically adjacent to each other and serve as fixing spaces, and a fixing tool having substantially the same cross-sectional shape as that of the spaces is inserted into the fixing spaces. A tile panel characterized by combining a ground plane. 2. The fixing space portion has a substantially circular cross-sectional shape, and the fixing tool has a cross-sectional shape whose major axis direction is slightly larger than the diameter of the space portion and whose minor axis direction is the space portion. The tile panel according to claim 1, wherein the tile panel is formed in an elliptical shape slightly smaller than a diameter. 3. The fixing tool is formed to be slightly larger than the cross-sectional dimension of the fixing space, and has a large number of streaks having a substantially triangular cross-section formed along the longitudinal direction on the outer peripheral surface. The tile panel described in 1. 4. The fixture has a tapered insertion guide portion formed at an end portion on the insertion side, and has a fixed length substantially equal to the length of the tile. The listed tile panel. 5. The tile back surfaces are respectively applied to the front surface of the base plate from the facing direction, and the engaging convex portions on the front surface side of the base plate are engaged with the engaging concave portions on the back surface side of the tiles to temporarily fix them, and then they are vertically adjacent to each other. For the fixing space formed by both grooves at the upper and lower ends of the matching tiles, the skewered shape or the individual space portions extending over each continuous hole-like space is fixed with the same cross-sectional shape as the space. A method of manufacturing a tile panel, characterized in that a base plate and a tile are combined and assembled by inserting a tool.
