Description

  The present invention relates to a tile unit and a construction method thereof, and more particularly to a tile unit capable of easily adjusting a joint width during construction and a construction method thereof.

  A tile unit in which a plurality of tiles are connected has better construction efficiency than a case where tiles are stretched one by one. As this tile unit, there is a tile unit with joints in which a net is bonded to the back surface of the tile and each tile is integrated by the net (Japanese Patent Laid-Open Nos. 4-30068 and 2005-256488).

  The tile unit disclosed in Japanese Patent Laid-Open No. 4-30068 is a biaxial net composed only of yarns in which the net crosses the joint. This net is bonded to the entire back surface of the tile with a thermoplastic synthetic resin. This synthetic resin is impregnated in a net, and the net is bonded to the tile by thermocompression bonding.

The net of the tile unit disclosed in Japanese Patent Application Laid-Open No. 2005-256488 has flexibility. The net is bonded to the entire tile back surface by an adhesive applied to the back surface of the tile or an adhesive applied to the net.
JP-A-4-30068 JP 2005-256488 A

  The net of the tile unit described in JP-A-4-30068 has high rigidity due to the curing of the thermoplastic synthetic resin. Therefore, the joint width cannot be adjusted during construction.

  In the tile unit disclosed in Japanese Patent Laid-Open No. 2005-256488, since the net has flexibility, the joint width can be reduced by hand during construction (paragraphs 0006, 0007, and 0018). However, since the net is attached to the entire back surface of the tile, the joint width cannot be increased by hand.

  In addition, even when adjusting to narrow the joint width, if the joint width is considerably narrowed, it will deform so that the net rises in the joint gap, resulting in poor construction. Adjustment of the joint width, which narrows the joint width, is limited to fine adjustment.

  An object of the present invention is to solve the above-mentioned conventional problems, and to provide a tile unit that can easily increase or decrease the joint width and adjust the joint unit and a construction method thereof.

  In the tile unit according to claim 1, a plurality of tiles are arranged through joint gaps, and the tiles are connected to each other through a net bonded to the back surface thereof, so that the joints are horizontal to the wall surface. The tile unit is a tile unit that is attached to the tile unit, and the net is a tile unit that is configured only by yarns obliquely intersecting the joints. In the tiles other than the uppermost stage and the lowermost stage, the net is The tile is adhered to the tile in the vicinity of the middle in the vertical direction of each tile, and is not adhered to the upper side and the lower side of the tile.

  The tile unit according to claim 2 is characterized in that, in claim 1, the crossing angle between the yarn and the horizontal joint is 30 to 60 °.

  The tile unit according to claim 3 is the tile according to claim 1 or 2, wherein the net is bonded to the upper side of the tile back surface in the vicinity of the middle in the vertical direction and is not bonded to the lower side. In the lowermost tile, the net is bonded to the lower side of the tile and near the middle in the vertical direction, and is not bonded to the upper side. It is.

  The construction method of the tile unit according to claim 4 is a method in which the tile unit according to any one of claims 1 to 3 is attached to a wall surface with an adhesive, and an adhesive is applied to the wall surface, The tile unit is pressed and attached to the wall surface sequentially from the upper tile while adjusting the joint width.

  In the tile unit of the present invention, in the tiles other than the uppermost and lowermost tiles, the net is not bonded to the upper side and the lower side of the tile. For this reason, when force is applied to widen or narrow the joint width, not only the part of the net that is located at the joint part, but also the back of the tile, the part that is free to the tile The net also grows and shrinks. Therefore, when construction is performed using this tile unit, it is possible to adjust the joint width to be considerably widened or conversely narrowed. Further, even when the joint width is considerably narrowed, the amount of shrinkage of the net in the joint portion is slight, and the net does not rise.

  As described in claim 2, by setting the crossing angle between the horizontal joint and the yarn to 30 to 60 °, the net can easily expand and contract in the joint width expansion or contraction direction.

  The joint along the uppermost and lowermost tiles is formed by non-adhering the lower side and the net in the uppermost tile and non-adhering the upper side and the net in the lowermost tile. The width can be adjusted more easily.

  Note that when the net is bonded to the upper side of the uppermost tile and the lower side of the lowermost tile, the edge of the net is prevented from turning up at this portion.

  Below, with reference to drawings, the tile unit which concerns on embodiment of this invention, and its construction method are demonstrated.

  FIG. 1 is a rear view and side view of a tile unit according to an embodiment of the present invention, FIG. 2 is an enlarged perspective view from the back side of the uppermost tile of the tile unit, and FIG. 3 is a view of the tile unit. It is a longitudinal cross-sectional view which shows the construction method. In FIG. 1, the left figure is a rear view of the tile unit, and the right figure is a side view of the tile unit.

  In the following description, the left-right direction and the up-down direction correspond to the left-right direction and the up-down direction in the rear view of the tile unit of FIG. The left-right direction and the up-down direction also coincide with the left-right direction and the up-down direction when the tile unit is viewed from the back side (wall side) when the tile unit is attached to the wall surface.

  In this tile unit 1, a plurality of tiles 2 are arranged with a gap between joints, and these tiles 2 are connected by a net 3 bonded to each back surface. The net 3 is composed only of yarns that obliquely intersect the joints between the tiles 2 and 2. In the tiles 2 other than the uppermost layer and the lowermost layer, the net 3 is bonded to the tiles 2 with an adhesive 4 in the vicinity of the middle in the vertical direction of the tiles 2 on the back surface of the tiles 2. The upper side and the lower side are not bonded.

  Below, the structure of each part of this tile unit 1 is demonstrated in detail.

  In this embodiment, the tile 2 has a substantially rectangular flat plate shape. As shown in FIG. 1, the tiles 2 are arranged in multiple rows in the left-right direction and in multiple rows in the up-down direction, with each long side direction being the left-right direction. In FIG. 1, the tiles 2 are arranged in three rows on the left and five columns on the top and bottom, but the arrangement of the tiles 2 is not limited to this. Further, the orientation of the tile 2 is not limited to this.

  Each tile 2 is a standard product, and the width in the vertical direction (that is, the short side direction, hereinafter the same) is 15 to 60 mm, and the width in the left and right direction (that is, the long side direction, the same applies hereinafter) is 45 to 45 mm. The thickness is 230 mm and the thickness is 5 to 18 mm.

  There are joint gaps between the long sides of adjacent tiles 2 and 2 and between the short sides. A joint gap between the long sides of the adjacent tiles 2 and 2 is a horizontal joint. The width of the joint gap is preferably 3 to 15 mm in a state where no external force is applied to the net 3 in either the direction of widening or narrowing the joint gap (hereinafter, this state is referred to as a normal state). Preferably it is 5-10 mm.

  In this embodiment, two concave strips 2b and 2b are formed on the back surface of each tile 2. These concave strips 2b, 2b each extend in the left-right direction, and are arranged with a predetermined gap above and below. The upper groove 2b is separated from the upper side of each tile 2, and the lower groove 2b is separated from the lower side of each tile 2. By these concave strips 2b and 2b, the back surface of each tile 2 is formed between the upper side of each tile 2 and the upper concave strip 2b, between these concave strips 2b and 2b, and the lower concave strip 2b. And a lower foot 2a made of ridges extending in the left-right direction is formed between each tile 2 and the lower side of each tile 2.

  In each tile 2, the back foot 2 a between the concave strips 2 b and 2 b (hereinafter sometimes referred to as a middle back foot 2 a) is located near the middle in the vertical direction of each tile 2.

  As shown in the rear view of the tile unit of FIG. 1 and FIG. 2, in this embodiment, the net 3 is a biaxial net constituted by yarns extending in two crossing directions, and its mesh shape. Is substantially square (preferably square or diamond). The net 3 is distributed so that the mesh diagonally crosses the joint gap between the tiles 2 and 2 and is superimposed on the back surface of the array of tiles 2.

  In the present invention, the net 3 is distributed so that the yarn extending in one of the two crossing directions and the yarn extending in the other intersect with the horizontal joint at a substantially equal angle in a bilaterally symmetrical manner. It is preferable. The crossing angle between each thread of the net 3 and the horizontal joint is preferably 30 to 60 °, particularly 40 to 50 °.

  As shown in FIG. 1, the net 3 is sized to cover substantially the entire back surface of the tile 2 array. The upper side, the lower side, the left side, and the right side of the net 3 are respectively the top tiles 2. The lower side of each tile 2 in the lowermost row, the left side of each tile 2 in the left end row, and the right side of each tile 2 in the right end row are cut.

  In this embodiment, in the tiles 2 other than the uppermost layer and the lowermost layer, the adhesive 4 is applied only to the back surface of the middle foot (the back foot with dots in FIG. 1) 2a among the back surfaces of the tiles 2. The net 3 is adhered only to the middle back foot 2a, and the upper side (that is, the upper recess 2b and the upper back foot 2a) and the lower side (that is, the lower recess 2b). And the lower back foot 2a) is not bonded.

  Further, in this embodiment, in the uppermost tile 2, only the back surface of the upper back foot 2a and the back surface of the middle back foot 2a with dots in FIG. Adhesive 4 is attached, and the net 3 is bonded only to the upper and middle back legs 2a, and the lower side (that is, the lower recess 2b and the lower back leg 2a). Is not bonded. The upper edge of the net 3 is bonded to the upper foot 2 a of the uppermost tile 2.

  Furthermore, in this embodiment, in the lowermost tile 2, only the back surface of the lower back foot 2a and the back surface of the middle back foot 2a marked with dots in FIG. Adhesive 4 is attached, and the net 3 is bonded only to the lower and middle back legs 2a, and the upper side (that is, the upper recess 2b and the upper back leg 2a). Is not glued. The lower edge portion of the net 3 is bonded to the lower foot 2a of the lowermost tile 2.

  The adhesive 4 may be applied to substantially the entire back surface of the back foot 2a to which the net 3 is to be bonded, and as shown in FIG. 2, the net 3 of the back foot 2a to which the net 3 is to be bonded. These yarns may be attached only to the overlapping portion. When the vertical width of the back foot 2a to which the net 3 is to be bonded is large, the net 3 may be bonded at two or more locations by changing the position on the back surface of the same back foot 2a.

  Therefore, in this tile unit 1, not only the portion of the net 3 exposed at the joint, but also the tile 2 other than the uppermost and lowermost tiers, the upper side of the back foot 2 a of the middle tier of each tile 2. The lower side net 3 contributes to the expansion and contraction. In the uppermost tile 2, the lower side net 3 contributes to the expansion and contraction than the middle foot 2a of each tile 2. In the lowermost tile 2 The net 3 on the upper side of the back foot 2a in the middle of each tile can contribute to the expansion and contraction.

  In the present invention, the net 3 is preferably configured so that the width of the joint can be expanded or narrowed from the normal state by 1 to 8 mm, particularly 3 to 5 mm.

  As the material of the net 3, chemical fibers such as polyethylene, polypropylene, and polyester are suitable.

  The thickness of the yarn of the net 3 is generally 0.5 to 5 mm, particularly preferably 1 to 3 mm, although it depends on the material.

  The length of one side of the substantially square mesh of the net 3 is preferably 18 to 40 mm, particularly preferably 20 to 30 mm. If the length of one side of the mesh is shorter than 18 mm, the net 3 is difficult to expand and contract. Further, if the length of one side of the mesh is longer than 40 mm, the number of adhesion points of the net 3 in each tile 2 is reduced, and the tile 2 is easily glazed when the tile unit 1 is lifted during construction. The mesh size of the net 3 is such that the number of adhesion points of the net 3 in each tile 2 (the number of yarns crossing the same back foot 2a to which the net 3 is to be adhered and the crossing portions of the yarns) is 2 to 2. It is preferable that the number is determined to be 5, especially 2 to 3.

  In the present invention, the net 3 is preferably bonded to each tile 2 at the intersection of the yarns or in the vicinity thereof. As a result, the adhesion of the net 3 to each tile 2 becomes a point adhesion, and this adhesion point acts like a hinge, so that the expansion / contraction function of the net 3 is impaired by adhering the net 3 to the tile 2. Is prevented or alleviated.

  Next, the construction method of the tile unit 1 configured as described above will be described.

  First, the vertical width of the wall surface 5 on which the tile unit 1 is constructed is measured. Then, the tile unit 1 can be distributed substantially evenly over the entire wall surface 5 without cutting the tile 2 of the tile unit 1 in the middle or adding cut tiles above and below the tile unit 1. Calculate the width.

  Next, after the adhesive 6 is applied to the wall surface 5, the tiles 2 are sequentially pressed and pasted to the wall surface 5 from the uppermost tile 2 of the tile unit 1 as shown in FIG. At this time, after pasting the uppermost tile 2, the second-tier tile 2 is pasted while the net 3 is stretched or compressed so that the joint width becomes a previously calculated width. Thereafter, the tiles 2 after the third stage are also attached to the wall surface 5 while adjusting the joint width in the same manner as the second stage.

  After pasting up to the lowest tile 2, the adhesive 6 is cured, whereby the pasting operation to the wall surface 5 of the tile unit 1 is completed.

  In the tile unit 1, as described above, in the tiles 2 other than the uppermost stage and the lowermost stage, the net 3 is bonded to the upper side and the lower side of the middle foot 2 a of each tile 2. In the uppermost tile 2, the net 3 is not bonded to the lower side of the middle foot 2a of each tile 2, and in the lowermost tile 2, the middle foot of each tile 2 is not bonded. The net 3 is not bonded to the upper side of 2a. For this reason, when force is applied to widen or narrow the joint width, not only the portion of the net 3 positioned at the joint but also the net 3 of the free portion facing the back surface of each tile 2 Stretch or shrink.

  Therefore, when this tile unit 1 is constructed, it can be adjusted so that the width of the joint is considerably widened or conversely narrowed. Even when the joint width is considerably narrowed, the shrinkage amount of the net 3 in the joint is small, and the net 3 does not rise in the joint.

  In this embodiment, since the crossing angle between the horizontal joint and each thread of the net 3 is set to 30 to 60 °, the net 3 is easily expanded and contracted in the joint expansion direction and the contraction direction.

  In this embodiment, the upper edge of the net 3 is bonded to the upper foot 2a of the uppermost tile 2, and the lower edge of the net 3 is bonded to the lower foot 2a of the lowermost tile 2. Therefore, the upper edge and the lower edge of the net 3 are prevented from being turned up from the back side of the tile 2.

  In this embodiment, on the back surface of each tile 2, two concave ridges 2 b, 2 b are formed at an interval in the vertical direction, so that the upper, middle and lower three back legs 2 a each made of a convex ridge. Is forming. In the tile 2 configured as described above, even when the adhesive 4 protrudes from the back foot 2a when the adhesive 4 is applied to the back surface of the back foot 2a to which the net 3 is to be bonded, this protrusion has occurred. The adhesive 4 enters the recess 2b. Therefore, the net 3 is bonded only to the back foot 2a to which the net 3 is bonded, and is not bonded to the other back foot 2a. Thereby, the tile unit 1 in which the net 3 is bonded only to the predetermined back foot 2a among the back surfaces of the tiles 2 can be manufactured easily and reliably.

  In addition, the back foot 2a and the groove 2b on the back surface of each tile 2 may be omitted.

  FIG. 4 is a back view and a side view of a tile unit using a tile in which the back foot 2a is not provided on the back surface. In FIG. 4, the left figure is a rear view of the tile unit, and the right figure is a side view of the tile unit.

  The tile 2A used in the tile unit 1A of FIG. 4 does not have the back foot 2a and the recess 2b formed on the back surface, and the back surface is a uniform flat surface.

  Also in this embodiment, as shown in FIG. 4, the tile 2A is a standard product having a substantially rectangular flat plate shape, and a plurality of tiles 2A are arranged in multiple rows in the left-right direction with the long side direction as the left-right direction. It is arranged in multiple stages in the vertical direction. Also in this embodiment, a horizontal joint is formed between the long sides of adjacent tiles 2A and 2A. In FIG. 4, the tiles 2A are arranged in three rows on the left and six columns on the top and bottom, but the arrangement of the tiles 2A is not limited to this. Further, the orientation of the tile 2A is not limited to this.

  Also in this embodiment, the net 3 is a biaxial net constituted by yarns extending in two crossing directions, and the mesh is distributed so as to obliquely cross the horizontal joint between the tiles 2A and 2A. It is overlaid on the back side of the array of tiles 2A.

  Also in this embodiment, in the tiles 2A other than the uppermost and lowermost stages, the net 3 is adhered only to the vicinity of the middle in the vertical direction on the back surface of each tile 2A, and the upper side and the lower side Is not bonded. In the uppermost tile 2A, the net 3 is bonded only to the middle and upper side of the tile 2A in the vertical direction of the back surface of each tile 2A, and is not bonded to the lower side. . Further, in the lowermost tile 2A, the net 3 is bonded only to the middle and lower sides of each tile 2A in the vertical direction of the back surface of each tile 2A, and is not bonded to the upper side. .

  As shown in FIG. 4, in this embodiment, the net 3 is distributed so that the intersections of the yarns are located in the vicinity of the middle in the vertical direction of the back surface of each tile 2A as much as possible. The portion or the vicinity thereof is bonded to each tile 2A by the adhesive 4 respectively. As a result, as described above, the adhesion of the net 3 to each tile 2A becomes a point adhesion, and this adhesion point acts like a hinge, so that the expansion and contraction of the net 3 is achieved by adhering the net 3 to the tile 2A. It is prevented or alleviated that the function is impaired.

  In addition, in the uppermost tile 2A, the net 3 is distributed so that the intersection of the yarns is located as close as possible to the vicinity of the upper side of the back surface of each tile 2A. Alternatively, the vicinity thereof is bonded to the vicinity of the upper side of the uppermost tile 2 </ b> A by the adhesive 4. Further, in the lowermost tile 2A, the net 3 is distributed so that the intersection of the yarns is located as close as possible to the vicinity of the lower side of the back surface of each tile 2A. Alternatively, the vicinity thereof is adhered to the vicinity of the lower side of the lowermost tile 2 </ b> A by the adhesive 4. By doing in this way, the number of the adhesion points with respect to each tile 2A of the upper edge part of the net | network 3 and a lower edge part can be decreased, and the saving of the adhesive agent 4 and the simplification of the adhesion | attachment process of the net | network 3 are aimed at. be able to.

  In this embodiment, the adhesive 4 is attached only at or near the intersection of the yarns. However, as in FIG. 1, the adhesive 4 may be applied to the back surface of each tile 2A in a strip shape in the left-right direction. Good.

  Other configurations of the tile unit 1A and preferable dimensions and the like of each part are the same as those of the tile unit 1 shown in FIGS. 4, the same reference numerals as those in FIGS. 1 to 3 denote the same parts. The construction procedure of the tile unit 1A is the same as that of the tile unit 1.

  In the tile unit 1A composed of the tiles 2A having the flat back surface as described above, the tile unit 1A is applied by applying the adhesive 6 to the wall surface 5 as shown in FIG. In the case of construction, when each tile 2A is pressed against the wall surface 5 and bonded, the adhesive 6 uniformly adheres to almost the entire back surface of each tile 2A through the mesh of the net 3, so that the adhesive strength is high. .

  The above embodiment shows an example of the present invention, and the present invention is not limited to the illustrated configuration.
