This construction method is characterized in that a large net is stacked vertically and horizontally on the entire outer wall, and tiles are stretched on the net using an adhesive.

JP 2005-133493 A

In the tile construction method described in Patent Document 1, during actual construction, an operator fixes a large-sized net over the entire outer wall, and a plurality of small tiles are stuck on the net. .
Thus, in order to fix the large-sized net so as to cover the entire outer wall without waste, it is necessary to work with a plurality of workers, or the end of this large-sized net is For example, it is necessary to perform an incidental operation such as fastening to the exterior material with a double-sided tape or the like, and workability is reduced.

In order for the worker to fix the large-sized net well on the entire exterior material of the outer wall, it was necessary to master skills. For this reason, workability may be reduced depending on the skill level of the worker.
Therefore, an object of the present invention is to provide a method for attaching a ceramic plate and a wall structure capable of achieving high workability without depending on the skill level of an operator.

The method for pasting a ceramic plate of the present invention is a method for pasting a ceramic plate with an adhesive on an existing wall structure of a building, and has a predetermined width and a plurality of openings. A plurality of strip-like members are laid at intervals on the construction surface of the wall structure, and the ceramic plate is attached to the construction surface with an adhesive.
According to the said structure, several elongate strip | belt-shaped members are laid in the construction surface at intervals. In the pasting method according to the present invention, the workability is high as compared with the case where the belt-like member is laid on the entire construction surface. Further, the work can be performed without depending on the skill of the worker.

Preferably, the existing wall structure includes a tile, and the plurality of elongated strip members are laid on the construction surface provided on the tile.
According to the said structure, the said ceramic plate can be simply affixed on the existing tile wall structure.

Preferably, the width is smaller than a length (dimension) along a vertical direction of the ceramic plate in a state of being attached to the construction surface.
According to the said structure, the width | variety of a strip | belt-shaped member is small. Therefore, workability at the time of laying a belt-like member on the construction surface is high. When the width of the belt-like member is large, for example, work by a plurality of workers may be required, or work such as fixing the end of the belt-like member with, for example, a double-sided tape may occur. Workability is reduced. In the present invention, even one worker can easily lay the belt-like member.

Preferably, one of the ceramic plates is pasted so as to cover a region of the construction surface where the elongated strip member is laid and a region of the construction surface where the elongated strip member is not laid. It is characterized by being.
According to the said structure, a ceramics board is affixed on two area | regions, the area | region which laid the strip | belt-shaped member, and the area | region which does not lay | belt the strip | belt-shaped member among construction surfaces.
In the construction method of the present invention, a ceramic plate is pasted in two regions, a region in which the belt-like member is laid and a region in which the belt-like member is not laid, using a large ceramic plate and a long belt-like member. For this reason, there are a region where the large ceramic plate is bonded and fixed to the belt-shaped member and a region where the large ceramic plate is bonded and fixed to the construction surface. Even if the adhesive force is weakened with time in one region, it can be expected to hold a large ceramic plate in the other region. Therefore, peeling from the construction surface of the ceramic plate is suppressed, and the durability of the wall structure can be enhanced.

Preferably, the adjacent elongate belt-like members adjacent to each other are laid on the wall surface so that the end portions on the long side do not overlap each other.
According to the said structure, the adhesive strength of a ceramic board can be raised. Further, the finished thickness can be reduced.

Preferably, the building includes a housing, and the elongated belt-like member is fixed to the housing by a fixture.
According to the said structure, since the strip | belt-shaped member fixed to the housing and the ceramic board are adhere | attached and fixed, durability of a wall structure can be improved more.

Preferably, the elongated strip member is fixed by a plurality of the fixtures at a pitch equal to or less than the arrangement pitch of the strip member for attaching the ceramic plate. It is characterized by.
According to the said structure, durability of a wall structure can further be improved.

Preferably, the ceramic plate is backed by a backing material.
According to the said structure, the impact resistance and bending strength of a large sized ceramic board can be ensured, and durability of a wall structure can be improved.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
The embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.

(First embodiment)
<Overall configuration of wall structure 1>
FIG. 1 is a perspective view showing a part of a wall structure formed by a method of attaching a ceramic plate according to the present invention. FIG. 2 is a diagram showing a cross-sectional structure taken along line AA of the wall structure 1 shown in FIG.
The wall structure 1 formed by the pasting method according to the present invention will be described with reference to FIGS. 1 and 2. In the present embodiment, a method of attaching a ceramic plate on a frame such as a lightweight steel structure (LGS structure) or a reinforced concrete structure (RC structure) will be described as an example. As shown in FIGS. 1 and 2, in this specification, the direction from the floor to the ceiling of the building is the vertical direction VL, and one of the directions orthogonal to the vertical direction VL is the horizontal direction HL, the vertical direction VL, and A direction orthogonal to the horizontal direction HL is defined as a depth direction SL. The vertical direction VL is a vertical direction in which the earth's gravity works, and is a vertical direction of the building. The horizontal direction is the horizontal direction of the building. The depth direction SL is, for example, the thickness direction of the ceramic plate 100 described later.

  As shown in FIG. 1, the wall structure 1 includes a housing 30, a base portion 6, a long belt-like member 10, an adhesive 20, and a ceramic plate 100. The band-shaped member 10, the adhesive 20, and the ceramic plate 100 are provided on the housing 30. The wall structure 1 has a wall surface 2. For example, the surface of the ceramic plate 100 (the surface opposite to the side on which the housing 30 is disposed) is the wall surface 2 of the wall structure 1.

<Housing 30>
For the frame 30, a lightweight steel structure (LGS structure), a reinforced concrete structure (RC structure), a wooden structure, or the like can be used. Since the strength calculation of the wall is easy, LGS construction or RC construction is preferable.
The housing 30 includes, for example, a plurality of pillars 5 and a plurality of girders 3 and 4. As shown in FIG. 1, the plurality of girders 3 and 4 are arranged in parallel at intervals along the horizontal direction HL. The plurality of column members 5 are arranged in parallel at intervals along the vertical direction VL. In this example, the plurality of girders 3 and 4 and the plurality of column members 5 are combined in a lattice shape.

<Background part 6>
In the LGS structure, the wooden structure, etc., the base portion 6 is provided on the housing 30, for example. The foundation | substrate part 6 has the construction surface 6A which lays the ceramic plate 100 mentioned later. The foundation | substrate part 6 contains a gypsum board, a plywood, etc., for example. In the case of RC construction, the surface of the casing 30 is the construction surface 6A of the base portion 6.

<Strip member 10>
Next, the elongate belt-like member 10 shown in FIGS. 1 and 2 will be described.
As shown in FIG. 1, the some strip | belt-shaped member 10 is laid in 6 A of construction surfaces at intervals. The plurality of belt-like members 10 are laid on a part of the construction surface 6A. As shown in FIGS. 1 and 2, the belt-like member 10 is a long member having a predetermined width 10W. Here, the width 10 W is the length in the short side direction of the long belt-like member 10. The strip-shaped member 10 has a plurality of openings 10H. A structure in which one opening 10H penetrates the front and back of the belt-like member 10 may be employed. A structure in which the plurality of openings 10 </ b> H communicate with each other and penetrate the front and back sides may be employed.
In the present invention, it is only necessary to lay the plurality of belt-like members 10 at intervals on the construction surface 6A, and the workability is higher than when the plurality of belt-like members 10 are laid on the entire surface of the construction surface 6A. Further, the work can be performed without depending on the skill of the worker.

The arrangement pitch DT of the belt-like members 10 is, for example, 450 mm to 900 mm. Here, the arrangement pitch DT is a distance between the centers in the width direction of the plurality of strip-shaped members 10. It is also preferable to lay adjacent strip members 10 apart so that the end portions on the long side do not overlap each other. As a result, the finished thickness can be reduced. Note that “adjacent” refers to two belt-like members 10 laid such that their longitudinal directions are substantially parallel. The belt-shaped member 10 may be laid so as to intersect so that the longitudinal direction thereof is substantially vertical.

  For example, the belt-like member 10 may be a long sheet, that is, a tape. For example, a mesh tape is preferably used for the band-shaped member 10. The mesh width of the mesh tape (size of the opening 10H) is, for example, 1 mm or more and 10 mm or less, a preferable lower limit is 2 mm, and a more preferable lower limit is 3 mm. When the eye width (size of the opening 10H) is smaller than 1 mm, the adhesive 20 described later does not easily pass through the eyes (opening 10H). When the mesh width is in the above range, the adhesive 20 can reliably reach the construction surface 6A through the eyes (opening 10H), which is preferable. Moreover, a preferable upper limit is 8 mm and a more preferable upper limit is 6 mm. By setting it as the said range, when fixing a mesh tape with the fixing tool 11 grade | etc., As mentioned later, it can fix reliably.

As the belt-like member 10, for example, a narrow net-like member may be used. As the band-like member 10, a roll-like member in which a sheet-like or net-like member is wound, or a strip-like member obtained by cutting these into short pieces may be used. In the case of a strip shape, the length may be adjusted to, for example, an arrangement pitch PS of screws (fixing tools 11) described later.

For the band-shaped member 10, for example, glass fiber, synthetic resin, synthetic fiber, carbon fiber, or a combination thereof can be used. Moreover, an expanded metal can be used. In the case where the belt-like member 10 includes glass fiber, alkali resistance treatment may be performed. As the alkali resistance treatment, for example, a treatment of coating glass fibers with a synthetic resin or the like can be used. For example, when the casing 30 is made of RC and the base portion 6 is processed using mortar, it is preferable to use the strip-shaped member 10 that has been subjected to alkali treatment.

In the example illustrated in FIGS. 1 and 2, the width 10W is smaller than the length 100L along the vertical direction VL of the ceramic plate 100 in a state where the width 10W is attached to the construction surface 6A. The width 10W is, for example, half or less of the length 100L. The width 10W of the belt-like member 10 is, for example, 10 mm or more and 500 mm or less. The width 10W of the belt-like member 10 is preferably 20 mm or more and 300 mm or less, and more preferably 30 mm or more and 100 mm or less. By setting the width 10W within the above range, for example, a single worker can easily lay the belt-like member 10.

If the width 10W is smaller than the lower limit value, the durability and the adhesive strength may be adversely affected. When the width 10W exceeds the upper limit, workability may be reduced.

When a large size sheet (for example, large net) such as 1000 mm is stretched on the entire construction surface 6A as in the case of pasting a small tile or the like, work by a plurality of workers is required. In addition, incidental work such as fixing the end of a large sized sheet with double-sided tape occurs, further reducing workability.
On the other hand, when attaching a large ceramic plate 100 as in the present invention, the band-like member 10 having a small width can be suitably used, and high workability can be obtained while ensuring sufficient adhesive strength and durability. Can do.

  An adhesive layer for temporarily fixing the long strip member 10 to the construction surface 6 </ b> A of the base portion 6 may be provided on the back surface of the long strip member 10. The operator's work becomes easy.

<Adhesive 20>
Next, the adhesive 20 will be described.
The ceramic plate 100 is attached to the construction surface 6A by the adhesive 20. The adhesive 20 is applied to, for example, the surface of the belt-like member 10 laid on the construction surface 6A and the region of the construction surface 6A where the belt-like member 10 is not laid. You may apply | coat to each whole of the area | region where the strip | belt-shaped member 10 is not laid among the surface of the strip | belt-shaped member and the construction surface 6A, and you may apply | coat to each one part.
As the adhesive 20, an adhesive suitable for the construction surface 6 </ b> A of the base portion 6 is used. Specifically, a synthetic resin adhesive (an epoxy adhesive, a urethane adhesive, a silicone adhesive, or an adhesive containing a synthetic resin in which they are combined) can be employed.

  When the wall structure 1 shown in FIG. 1 is an outer wall of a building, a silicone-based or mortar-based adhesive (mortar or resin mortar) can be used as the adhesive 20. For the outer wall, it is more preferable to use a silicone-based adhesive. Depending on the construction method, a double-sided tape can be used in combination with the adhesive 20.

<Large ceramic plate 100>
Next, the ceramic plate 100 of the present invention will be described.
As for the size of the large ceramic plate 100, one side is, for example, 600 mm or more (in the case of a rectangle, the short side is preferably 600 mm, 900 mm, or 1000 mm, and the long side is 900 mm, 1000 mm, 1800 mm, 2000 mm, 2400 mm. One of 3000 mm). As the large-sized ceramic plate 100, a thin and large-sized ceramic plate having a thickness of 3 mm or more and 12 mm or less can be suitably used. A more preferable thickness of the large-sized ceramic plate 100 is 3 mm or more and 9 mm or less. As the material for the large-sized ceramic plate 100, those having a ceramic quality, a texture, and a porcelain quality can be adopted.

The large ceramic plate 100 is preferably attached to the construction surface 6A so as to cover, for example, a region of the construction surface 6A where the belt-like member 10 is laid and a region where the belt-like member 10 is not laid. In this way, the ceramic plate 10 is attached to the two regions of the construction surface 6A. Therefore, the ceramic plate 100 is firmly attached to the construction surface 6A, and peeling of the ceramic plate 100 from the construction surface 6A is suppressed.
Is prevented from peeling.

As shown in FIG. 1 and FIG. 2, the large ceramic plate 100 has an upper portion 100u located on the upper side (ceiling side) and a lower portion located on the lower side (floor side) in a state of being laid on the construction surface 6A. Part 100d. In this example, it further has a middle part 100c located between the upper part 100u and the lower part 100d.
In this example, when projected onto a plane perpendicular to the depth direction SL, for example, the first band member 10a among the plurality of band members 10 overlaps the upper portion 100u of the ceramic plate 100. For example, the second strip member 10 b overlaps the lower portion 100 d of the ceramic plate 100. In this example, the third belt-like member 10 c overlaps the middle portion 100 c of the ceramic plate 100. Thereby, the ceramic plate 100 is uniformly affixed to the construction surface 6A, and the necessary affixing strength can be ensured.

  The surface of the large ceramic plate 100 may have high antiviral properties and antibacterial properties. Specifically, for example, a layer having photocatalytic activity may be provided on the surface of the large-sized ceramic plate 100. In this case, the photocatalytic action can reduce bacteria that cause odor and dirt. Moreover, when the surface of the ceramic plate 100 further contains an antibacterial metal, an antibacterial effect can be obtained even in a place where light does not strike.

<Backing material 101>
As shown in FIGS. 1 and 2, the large ceramic plate 100 is preferably backed by a backing material 101. Thereby, the ceramic plate 100 is reinforced. For this reason, even if the ceramic plate 100 is large, impact resistance and bending strength can be ensured.
The backing material 101 includes, for example, a glass fiber woven fabric, nonwoven fabric, or synthetic fiber woven fabric, nonwoven fabric, or synthetic resin net. The backing material 101 may be a board made of wood, metal, or synthetic resin. As the backing material 101, it is more preferable to use a woven fabric or net made of glass fiber, or a net made of synthetic resin. When these nets are used as the backing material 101, the adhesive strength between the adhesive and the large-sized ceramic plate 100 can be further improved by the net of the backing material, and more excellent durability can be obtained.

<Pasting method>
Next, an example of a pasting method for forming the wall structure of FIGS. 1 and 2 will be described. <Pretreatment of construction surface 6A>
Before laying the belt-like member 10 on the construction surface 6A, pretreatment of the construction surface 6A is performed as necessary. The pretreatment is preferably performed when a ceramic plate is laid on a wall structure including an existing wall structure, such as wall repair of an existing building. If the building is a new construction, pre-processing is not necessary. Details of this pre-processing example will be described later.

<Laying the long belt-like member 10>
Next, laying of the long belt-like member 10 will be described.
A plurality of belt-like members 10 are laid on the construction surface 6A at intervals. It is preferable that the long-side ends of the belt-like member 10 are laid apart so as not to overlap each other. In this example, as shown in FIG. 1, the long belt-like members 10 are separated from each other at a predetermined interval (arrangement pitch DT) in the width 10W direction, and the longitudinal direction of the belt-like member 10 is the construction surface 6A. The base 6 is laid on the construction surface 6A so as to be parallel to the horizontal direction HL. When the casing 30 is made of LGS, it is particularly preferable to lay the strip-like member 10 in parallel so that the longitudinal direction of the strip-like member 10 is along the horizontal direction HL.
By laying the belt-like member 10 so as not to overlap, the adhesive strength of the ceramic plate 100 can be increased. Further, the finished thickness can be reduced. Further, the belt-like member 10 is laid on the construction surface 6A so that the longitudinal direction thereof is parallel to the horizontal direction of the construction surface 6A. In this case, since the longitudinal direction of the strip-shaped member 10 is arranged so as to be orthogonal to the vertical direction VL, the effect of suppressing the peeling of the ceramic plate 100 is enhanced.

An example of a method for laying the belt-like member 10 will be described. For example, the operator presses the long belt-like member 10 with one hand. And an operator temporarily fixes the elongate strip | belt-shaped member 10 using a tucker etc. with the other hand. When the belt-like member 10 is in the form of a roll, the long belt-like member 10 is cut in accordance with the size of the construction surface 6A in a temporarily fixed state.
Then, it is preferable to fix each strip | belt-shaped member 10 to the housing 30 using the some fixing tool 11, for example. In this case, the worker fixes the long belt-like member 10 with a fixture 11 (for example, a screw). When the casing 30 is a lightweight steel structure (LGS structure) or a wooden structure, the belt-like member 10 is fixed to the casing 30 (for example, a column, a stud, etc.) by the fixture 11.

A plurality of fixtures 11 are provided. The plurality of fixtures 11 are provided, for example, separated by a predetermined arrangement pitch PS. Here, the arrangement pitch PS is a distance between the centers of two fixtures that are adjacent to each other along the laying direction (longitudinal direction) of the elongated belt-like member 10. The arrangement pitch PS of the fixtures 11 is preferably made to correspond to, for example, the arrangement pitch of the pillars 5, and more preferably equal to or less than the width of the large-sized ceramic plate 100.
A screw, a washer, a plug anchor, a wood screw, etc., and combinations thereof can be used for the fixture 11 according to the housing 30. As the fixture 11, for example, a screw, a plug anchor, a wood screw, or a combination thereof can be used. When the housing 30 is made of LGS, for example, a lightweight steel frame screw or washer can be used as the fixture 11. When the frame 30 is reinforced concrete (RC), a combination of a plug anchor and a screw can be suitably used as the fixture 11. In this case, the arrangement pitch PS of the plug anchor (fixing tool 11) is preferably set to 300 mm to 400 mm, for example.
By using the fixture 11, the belt-like member 10 can be more firmly held on the housing 30.

<Application of adhesive 20>
Next, a method for applying the adhesive 20 will be described. In a state where a plurality of long belt-like members 10 are laid on the construction surface 6A of the base portion 6, the adhesive 20 is applied to the entire construction surface 6A, for example. Here, the entire surface refers to both the region of the construction surface 6A where the belt-like member 10 is laid and the region of the construction surface 6A where the belt-like member 10 is not laid. A part of the adhesive 20 in FIG. 2 passes through the opening 10 </ b> H of the elongated belt-like member 10 and reaches the construction surface 6 </ b> A of the base portion 6. The adhesive 20 may be applied to a part of a region where the belt-like member 10 is laid and a part of a region where the belt-like member 10 is not laid. The adhesive 20 may be applied to the back surface of the ceramic plate 100 or the surface of the backing material 101, for example. In this case, when the ceramic plate 100 is pasted, it is preferable to apply so that both the area where the belt-like member 10 is laid and the area where the band-like member 10 is not laid overlap with the adhesive 20.
For applying the adhesive 20, a comb iron or a caulking gun can be used. When the adhesive 20 is applied to the back surface of the ceramic plate 100 or the surface of the backing material 101, a bead can be applied using a comb iron or a caulking gun. In the case of applying to the construction surface 6A, beads can be applied using a caulking gun.

<Attaching the ceramic plate 100>
Next, a method for attaching the large ceramic plate 100 to the construction surface 6A of the base portion 6 will be described. As shown in FIG. 2, the operator presses the back surface of the large-sized ceramic plate 100 (the back surface of the backing material 101) against the construction surface 6A. At this time, for example, one ceramic plate 100 is attached so as to cover a region of the construction surface 6A where the belt-like member 10 is laid and a region of the construction surface 6A where the belt-like member 10 is not laid. Therefore, the ceramic plate 10 is firmly attached to the construction surface 6A. Peeling from the construction surface 6A of the ceramic plate 100 is suppressed.

According to the construction method according to the present invention, not only adhesive strength and durability can be sufficiently secured, but also workability at a construction site is excellent. Further, by using the large ceramic plate 100, it is possible to reduce the load on the wall structure 1 as compared with the case where a large number of small tiles are attached.
Thereafter, if necessary, the appearance of the wall structure 1 can be further improved by performing jointing between the adjacent large-sized ceramic plates 100.

In addition, according to the construction method which concerns on this invention, you may combine the large sized ceramic plate 100 and other finishing materials. As other finishing materials, for example, a large stone plate, a wood plate, a metal plate, or the like can be used. By combining these with the ceramic plate 100, a desired design can be obtained.

  Moreover, the elongate strip | belt-shaped members 10B and 10C shown in FIG. 4 and FIG. 5 have the area expansion parts 10L and 10R, respectively. The area enlarged portions 10L and 10R are portions having a width 10W larger than other portions. By using the long strip members 10B and 10C, the bonding ability of the large ceramic plate 100 can be improved.

The other part of the plurality of belt-like members 10 is laid parallel and spaced apart from each other in the width 10W direction so that the longitudinal direction thereof is along the vertical direction VL of the construction surface 6A.
When the housing 30 is made of LGS or wood, as shown in FIG. 6, the long belt-like member 10 is laid so that its longitudinal direction is parallel to the direction HL horizontal to the floor surface. It is preferable to do. The belt-like member 10 may be further laid so that the longitudinal direction thereof is parallel to the direction VL perpendicular to the floor surface. In this case, the pitch in the width 10W direction between adjacent long belt-like members 10, that is, the width of the other long belt-like member 10 from the center in the width 10W direction of one long belt-like member 10. The arrangement pitch DT to the center in the 10W direction is preferably 450 mm to 900 mm. The arrangement pitch DT varies depending on the allocation of the large ceramic plate 100.

In addition, as illustrated in FIG. 7, when the housing 30 is made of RC, the long belt-like member 10 can be laid in a direction ML oblique to the floor surface.
As illustrated in FIG. 7, the arrangement pitch DT of the long belt-like members 10 is, for example, 450 mm to 900 mm.

The second embodiment of the present invention is a method of overlaying a large ceramic plate 100 on an existing wall structure. The foundation | substrate part 6 contains the material which comprises the existing wall structure, for example, a tile, wallpaper, a gypsum board, a plywood etc., for example. In this case, it is preferable to pre-process the construction surface 6A.
First, the housing 30 is confirmed. In the case where the existing wall structure case 30 is, for example, an RC structure, first, it is confirmed whether the case 30 has structural cracks, efflorescence, water leakage, or the like. For example, when the strength of the housing is remarkably deteriorated, when there is a structural crack, when the efflorescence is remarkable, or when there is water leakage and significant moisture, repair is performed as appropriate. Thereafter, the belt-like member 10 is laid on the construction surface 6A. For example, when the existing wall structure housing 30 is made of LGS, the frame size and the column pitch are confirmed. When the ceramic plate 10 is overlaid on the existing wall structure, the strength calculation of the wall structure 1 is easy and it is easy to determine whether or not the upholstery is possible. Therefore, the existing wall structure housing 30 is made of RC or LGS. It is preferable that

Next, the state of the construction surface 6A is confirmed.
For example, if the existing wall structure finish includes wallpaper, the areas with significant fouling, flaking or floating are peeled off. If the base material of the existing wall structure is, for example, gypsum board or plywood, replace the existing base material of the wall structure if there is fouling, loss, cracking, warpage, etc. To do. When the existing finishing material of the wall structure includes a paint finish, the coating film on the defective part such as peeling or floating is removed. In addition, when the existing wall structure is finished with tiles, for example, the floating tiles are removed, and using the base conditioner (putty, mortar (including resin mortar)), the recesses caused by the removed tiles. Fill up and align the height with the surroundings. When the level difference between the tile joints, that is, the level difference between the tiles and the joints is 2 mm or more, the tile around the part is peeled off, or the base is adjusted using an adhesive or a base adjustment material. Thus, it is preferable to implement pre-processing so that the unevenness | corrugation of the construction surface 6A surface may be eliminated.

  After the pretreatment as described above, the ceramic plate 100 is pasted on the existing wall structure including the tile. At this time, the method already described can be used. That is, a plurality of belt-like members 10 can be laid on the construction surface 6A at intervals, and the ceramic plate 100 can be attached thereon.

As described above, the method for pasting a ceramic plate according to the present invention can be used particularly suitably when the ceramic plate is overlaid on an existing wall structure. For example, when overlaying an existing wall structure in which a large number of small tiles are attached, the entire surface of the existing wall structure is covered with a sheet or the like in order to suppress peeling of the small tiles from the existing wall structure. In some cases, a method of overlaying is used.
On the other hand, in the construction method according to the present invention, a plurality of belt-like members having a predetermined width are laid at intervals, and a large ceramic plate is attached. With this combination, it is possible to suppress the peeling from the existing wall structure and obtain a sufficient adhesive strength of the ceramic plate while ensuring high workability by simple construction.

  In an embodiment of the present invention, a ceramic plate is affixed with an adhesive to an existing wall structure of a building with an adhesive, and has a predetermined width and a plurality of openings. A plurality of strip members are laid on the construction surface of the wall structure at intervals, and the ceramic plate is attached to the construction surface with an adhesive.

Thereby, a ceramic board can be fixed to the construction surface provided on the existing wall structure. In addition, the worker only lays a plurality of long belt-like members on the construction surface at intervals, for example, compared to the case of laying the construction surface without any gaps on the operator's skill side. It is possible to improve the workability of attaching the ceramic plate without depending on the proficiency.
According to the method for pasting a ceramic plate of the embodiment of the present invention, the construction of a large ceramic plate is simple and the finished thickness is thin, and no cracks are caused by the movement or expansion / contraction of the outer wall. By attaching a large ceramic plate, the load on the wall structure is reduced as compared to attaching a plurality of small ceramic plates. A large ceramic plate can be overlaid on the existing wall structure with tiles attached. Moreover, even if peeling or the like occurs in an existing wall structure tile, for example, a combination of a large ceramic plate and a long belt-like member attached on the tile can suppress the occurrence of problems as a wall structure.

  By using a large ceramic plate and a narrow strip-shaped member in a narrow width, laying workability can be greatly improved and sufficient adhesive strength and durability can be obtained.

  The width of the long belt-like member is smaller than the length (length in the vertical direction) along the vertical direction of the ceramic plate in a state of being attached to the construction surface. By using such a narrow band-shaped member, compared with the case where the entire outer wall is covered vertically and horizontally with a large net, for example, work such as fastening the end of the large net with double-sided tape is unnecessary, Workability when laying members is remarkably excellent.

  One ceramic plate is attached so as to cover a region of the construction surface where the long belt-like member is laid and a region of the construction surface where the long belt-like member is not laid. Thereby, the ceramic plate can be fixed in two regions, that is, a region bonded to the construction surface and a region bonded to the long strip member, and the ceramic plate can be firmly attached to the construction surface. Moreover, peeling from the construction surface of the ceramic plate is suppressed. Generation of cracks due to movement and contraction of the outer wall is suppressed.

  Adjacent long belt-like members are laid on the construction surface so as to be separated so that the end portions on the long side do not overlap each other. By keeping adjacent long belt-shaped members from overlapping each other, a large ceramic plate can be securely held using a plurality of long belt-shaped members and an adhesive, and the ceramic plate can be held. Power is obtained. Furthermore, the finished thickness can be reduced.

  The building includes a frame, and the long belt-like member is fixed to the frame by a fixture. For this reason, even when the adhesive strength of the adhesive is weakened due to deterioration over time, the ceramic plate can be fixed to the casing, and durability can be improved. In addition, when a ceramic plate is overlaid on an existing wall structure including tiles, the tiles of the existing wall structure may peel off due to deterioration over time. Also in this case, the fall of the tile can be suppressed by fixing the belt-like member with a fixture. Further, since a large ceramic plate is used, even if a part of an existing wall structure tile is peeled off, the large ceramic plate can suppress the peeling from the wall structure.

  The long belt-like member is fixed by a plurality of fixtures, and the arrangement pitch of the plurality of fixtures is the same as or smaller than the arrangement pitch of the long belt-like members. Thereby, a plurality of long strip members can be fixed to the housing side by a plurality of fixtures, and a large ceramic plate can be securely held by using a plurality of long strip members and an adhesive. And the holding power of the ceramic plate can be obtained.

  The ceramic plate is lined with a backing material. Thereby, in order to hold | maintain a ceramic plate | board by the synergistic effect of a elongate strip | belt-shaped member and a backing material, the outstanding durability is obtained.

The wall structure of the present invention is constructed by the above-described method of pasting ceramic plates.
That is, a long strip member having a predetermined width is laid on the construction surface at an interval, and the ceramic plate is attached with an adhesive. The adhesive reaches the construction surface through the opening of the elongated belt-like member. The ceramic plate is fixed to the construction surface by an adhesive and a plurality of elongated strip members. In addition, the worker only lays a plurality of elongated strip members on the construction surface at intervals, and improves the work of attaching the ceramic plate without depending on the skill of the worker. Can do.
