Description

本発明は、壁面へのタイルの施工方法に関するものである。   The present invention relates to a method for constructing a tile on a wall surface.

壁面に複数のタイルを張付けるにあたっては、複数のタイルの表面に台紙が貼着されてユニット化されたユニットタイルが知られている。特許文献１には、このようなユニットタイルの取り扱いを容易化する等の目的で、裏面に補強材を設ける等して強固なパネル体とすることが提案されている。また、特許文献２には、施工したタイルの剥離による脱落防止を目的として、タイルの裏面に連結部材を事前に接着し、これにより複数のタイルを連結することが提案されている。また、特許文献３には、施工したタイルの剥離による脱落防止を目的として裏面に連結部材をあらかじめ配したユニットタイルの張付け後に固定具でユニットタイルを壁面に機械的に固定するものが提案されている。   In pasting a plurality of tiles on a wall surface, a unit tile is known in which a mount is attached to the surface of a plurality of tiles to form a unit. Japanese Patent Application Laid-Open No. H10-228667 proposes a strong panel body by providing a reinforcing material on the back surface for the purpose of facilitating the handling of such unit tiles. Further, Patent Document 2 proposes that a connecting member is bonded in advance to the back surface of a tile to thereby connect a plurality of tiles for the purpose of preventing falling off due to peeling of the applied tile. Further, Patent Document 3 proposes a method in which a unit tile is mechanically fixed to a wall surface with a fixture after the unit tile having a connecting member arranged in advance on the back surface is attached for the purpose of preventing falling off due to peeling of the applied tile. Yes.

躯体に固定具等を併用して張付けたタイルの剥離による脱落防止を図るためには、タイル間を連結することが望ましい。しかし、特許文献１のように事前にパネル状になるまで固めてしまうと、各タイル間の目地幅が調整できなくなると共にパネル状とするための事前準備の手間がかかる。   It is desirable to connect the tiles in order to prevent falling off due to peeling of the tiles that are attached to the frame using a fixture or the like. However, if it is hardened in advance until it becomes a panel shape as in Patent Document 1, the joint width between the tiles cannot be adjusted, and it takes time to prepare in advance for making the panel shape.

特許文献２のように連結部材を事前にユニットタイルの各タイル裏面に点接着する手法の場合、各タイルは、表面側の台紙と裏面側の連結部材で支持され、ユニット全体をパネルのように扱うことができるので、既存の手張り工法を簡単に採用できるだけでなく、従来のユニットタイルより扱いやすいという施工上の利点を有している。しかし、目地幅の調整はある程度は可能ではあるが連結部材の伸縮性の範囲であり、調整しづらい。更に、連結部材を事前に接着しておく必要があるため、準備に手間がかかる。   In the case of the technique in which the connecting member is point-adhered to the back surface of each tile of the unit tile in advance as in Patent Document 2, each tile is supported by the front side mount and the back side connecting member, and the entire unit is like a panel. Since it can be handled, it has the construction advantage of being easier to handle than conventional unit tiles as well as easily adopting the existing handrail construction method. However, although the joint width can be adjusted to some extent, it is within the range of stretchability of the connecting member and is difficult to adjust. Furthermore, since it is necessary to bond the connecting member in advance, it takes time to prepare.

本発明の目的は、施工したタイルの剥離による脱落防止を図るにあたり、目地幅の調整が容易であり、しかも、事前にユニットタイルの裏面に連結部材を接着しておく手間を削減することにある。   An object of the present invention is to easily adjust the joint width in order to prevent falling off due to peeling of a tile that has been applied, and to reduce the effort of adhering a connecting member to the back surface of a unit tile in advance. .

本発明によれば、ユニットタイルを壁面に張付けるユニットタイルの施工方法において、前記ユニットタイルを壁面に張付ける段階で、前記ユニットタイルの裏面にタイル間を連結する連結部材を単に載せただけの状態としてその上から張付けモルタルを塗り込み、続いて前記ユニットタイルを壁面に張付けることを特徴とするユニットタイル施工方法が提供される。 According to the present invention, in the unit tile construction method for attaching the unit tile to the wall surface, the connecting member for connecting the tiles is simply placed on the back surface of the unit tile in the step of attaching the unit tile to the wall surface . There is provided a unit tile construction method characterized in that a mortar is applied from above as a state and then the unit tile is attached to a wall surface.

本発明によれば、施工したタイルの剥離による脱落防止を図るにあたり、目地幅の調整が容易であり、しかも、事前にユニットタイルの裏面に連結部材を接着しておく手間を削減することができる。   According to the present invention, it is easy to adjust the joint width in preventing the falling off due to peeling of the applied tile, and it is possible to reduce the trouble of adhering the connecting member to the back surface of the unit tile in advance. .

図１は本発明のユニットタイル施工方法により実現される、ユニットタイルの施工構造例の一部分解斜視図である。同図の施工構造例では、ユニットタイル１０が連結部材２０を介在させて、張付けモルタル３０により、建築躯体の壁面１に張付けられている。   FIG. 1 is a partially exploded perspective view of a unit tile construction structure realized by the unit tile construction method of the present invention. In the construction structure example shown in the figure, the unit tile 10 is attached to the wall surface 1 of the building frame by the attaching mortar 30 with the connecting member 20 interposed.

本実施形態の場合、ユニットタイル１０は、複数のタイル１１の表面１１ａに台紙１２が貼着されてユニット化されたものである。なお、台紙１２での連結に代えて、樹脂などによってタイル１１の裏面・側面を部分的に連結する場合もある。   In the case of this embodiment, the unit tile 10 is unitized by mounting a mount 12 on the surface 11 a of the plurality of tiles 11. In addition, it may replace with the connection in the base_sheet | mounting_paper 12, and the back surface and side surface of the tile 11 may be partially connected with resin etc.

各タイル１１はいずれも同形状（方形）をなしている。台紙１２は、例えば、紙、樹脂フィルム等のシート或いはネットからなり、複数のタイル１１が上下左右の目地幅分だけ空隙をおいて配列されて貼り付けられている。後述するようにこの台紙１２は施工後に剥離される。   Each tile 11 has the same shape (square). The mount 12 is made of, for example, a sheet of paper, a resin film, or a net, and a plurality of tiles 11 are arranged and pasted with gaps corresponding to the joint widths in the vertical and horizontal directions. As will be described later, the mount 12 is peeled off after the construction.

連結部材２０は、本実施形態の場合、ビニロン繊維から成るメッシュシートを想定するが、張付けモルタル３０がタイル１１の裏面に浸透可能な耐アルカリ性を有するメッシュ状のものであればよい。連結部材２０の大きさは、台紙１２とほぼ同じで、ユニットタイルの大きさより各辺５ｃｍ程度小さくすることが好ましい。張付けモルタル３０は、例えば、既調合の張付けモルタルや増粘保水剤を添加したセメントモルタルである。 Connecting member 20, in this embodiment, but assumes a mesh sheet made of vinylon fibers, laying mortar 30 is acceptable as long as a mesh shape having a permeable alkali resistance on the back of the tile 11. The size of the connecting member 20 is substantially the same as that of the mount 12 and is preferably about 5 cm smaller on each side than the size of the unit tile. The pasting mortar 30 is, for example, a cement mortar to which a pre-prepared pasting mortar or a thickening water retention agent is added.

固定具４０は、ユニットタイル１０を壁面１に機械的に固定する器具である。固定具４０は、ユニットタイル１０を壁面１に張付けして張付けモルタル３０の強度が出た後（例えば２日以上後）、複数のタイル１１間の目地に、連結部材２０を通過して壁面１に接続される。なお、図１においては図示していないが、固定具４０の配設後、タイル１１間の目地に目地材が詰められることになる。   The fixture 40 is an instrument that mechanically fixes the unit tile 10 to the wall surface 1. After the unit tile 10 is stuck to the wall surface 1 and the strength of the tension mortar 30 comes out (for example, after two days or more), the fixture 40 passes the connecting member 20 to the joint between the plurality of tiles 11 and passes through the wall surface 1. Connected to. Although not shown in FIG. 1, the joint material is filled in the joint between the tiles 11 after the fixture 40 is disposed.

次に、図２及び図３を参照して本発明の一実施形態に係るユニットタイル施工方法について説明する。図２（ａ）乃至（ｃ）及び図３（ａ）及び（ｂ）において、各図の左側はユニットタイル１０に対する作業をその側方から見た図であり、右側は作業後のユニットタイル１０を上方から見た図である。   Next, a unit tile construction method according to an embodiment of the present invention will be described with reference to FIGS. 2A to 2C and FIGS. 3A and 3B, the left side of each figure is a view of the work on the unit tile 10 from the side, and the right side is the unit tile 10 after the work. It is the figure which looked at from the upper part.

本実施形態では、ユニットタイル１０の各タイル１１と連結部材２０とを接着する等して事前に連結状態としないことを一つの特徴としている。そして、ユニットタイル１０を壁面１に張付ける段階で、連結部材２０の配設作業等を行う。このため、図２（ａ）に示すように、施工現場、好ましくはユニットタイル１０の張付け対象である壁面１の近傍において、作業台２を設け、その上に、台紙１２が貼着された状態のユニットタイル１１を台紙１２を下に、タイル１１の裏面１１ｂを上にして載置する。なお、特に図示していないが、タイル１１の裏面１１ｂには、張付けモルタル３０との結合性を向上する凹凸（例えば溝、特に蟻溝）が適宜設けられる。   In this embodiment, one feature is that each tile 11 of the unit tile 10 and the connecting member 20 are not connected in advance by bonding or the like. Then, at the stage of attaching the unit tile 10 to the wall surface 1, the disposing operation of the connecting member 20 is performed. For this reason, as shown to Fig.2 (a), in the construction site, Preferably the work table 2 is provided in the vicinity of the wall surface 1 to which the unit tile 10 is attached, and the mount 12 is adhered thereon. The unit tile 11 is placed with the mount 12 facing down and the back surface 11b of the tile 11 facing up. Although not particularly illustrated, the back surface 11b of the tile 11 is appropriately provided with unevenness (for example, a groove, particularly a dovetail groove) for improving the bonding property with the tension mortar 30.

作業台２はユニットタイル１０を載置可能な略水平面が確保できればどのようなものであってもよく、壁面１が地上近くであれば地面上に作業台２を設置すればよい。また、マンション等の壁面のうち、地上から離れた中層階、上層階の壁面にユニットタイル１０を張付ける場合、図５に示すように建物の壁面に沿って設けられた足場１００に設けることもできる。   The work table 2 may be anything as long as a substantially horizontal plane on which the unit tile 10 can be placed is secured. If the wall surface 1 is near the ground, the work table 2 may be installed on the ground. In addition, when unit tiles 10 are attached to the wall surfaces of the middle and upper floors apart from the ground among the wall surfaces of apartments, etc., they may be provided on a scaffold 100 provided along the wall surface of the building as shown in FIG. it can.

図５の例では、バルコニー近傍の壁面１にユニットタイル１０を張付ける場合を想定しており、上下の階層のバルコニー間のスペースに突出するように作業台１０１を足場１００に設けている。このように建物の凹凸により形成されるスペースを利用することで、空きのスペースを作業台１０１の設置スペースとして有効活用できる。   In the example of FIG. 5, it is assumed that the unit tile 10 is attached to the wall surface 1 near the balcony, and the work platform 101 is provided on the scaffold 100 so as to protrude into the space between the balconies on the upper and lower levels. By using the space formed by the unevenness of the building in this way, an empty space can be effectively used as the installation space for the work table 101.

図２に戻り、作業台２上にユニットタイル１０を載置すると、図２（ｂ）に示すようにその上に連結部材２０を載置する。連結部材２０はユニットタイル１０の裏面１１ｂ上に載置されるだけなのでタイル１１間を連結しない。なお、連結部材２０は単にユニットタイル１０の裏面１１ｂに乗っているだけなので、強風が吹くと飛ばされるおそれがある。よって、作業台２の周囲には風除けを設けておくことが好ましい。風除けとしては、養生メッシュシート等を挙げることができる。上述した図５の例のように足場１００に作業台１０１を設けた構成においては、同図に示すように足場１００に養生メッシュシート１０２を設けて風除けとすることが好ましい。   Returning to FIG. 2, when the unit tile 10 is placed on the work table 2, the connecting member 20 is placed thereon as shown in FIG. Since the connecting member 20 is only placed on the back surface 11b of the unit tile 10, the tiles 11 are not connected. In addition, since the connection member 20 is only on the back surface 11b of the unit tile 10, there is a possibility that the connection member 20 may be blown off when a strong wind blows. Therefore, it is preferable to provide a windshield around the work table 2. Examples of windbreaks include a curing mesh sheet. In the configuration in which the work platform 101 is provided on the scaffold 100 as in the example of FIG. 5 described above, it is preferable to provide a curing mesh sheet 102 on the scaffold 100 as a windshield as shown in FIG.

連結部材２０を載置すると、図２（ｃ）に示すようにマスク材３をその上に載置する。マスク材３は各タイル１１の裏面１１ｂ部分の９０パーセント程度が露出するように開口し、目地部分を塞ぐシート体或いは板体であり、通常のマスク張りに使われるものである。   When the connecting member 20 is placed, the mask material 3 is placed thereon as shown in FIG. The mask material 3 is a sheet or plate that opens so that about 90% of the back surface 11b of each tile 11 is exposed and closes the joint, and is used for normal masking.

次に、マスク材３の上から各タイル１１の裏面１１ｂに張付けモルタル３０を塗り込む。図３（ａ）は鏝４により張付けモルタル３０を塗り込む工程を示している。張付けモルタル３０は連結部材２０を通過してタイル１１の裏面に塗り込まれる。   Next, the mortar 30 is applied to the back surface 11 b of each tile 11 from above the mask material 3. FIG. 3A shows a process of applying the sticking mortar 30 with the scissors 4. The sticking mortar 30 passes through the connecting member 20 and is applied to the back surface of the tile 11.

次に、マスク材３を取り除き（図３（ｂ））、図３（ｃ）に示すようにユニットタイル１０を壁面１に張付ける。その際、同図に示すように壁面１にも張付けモルタル３０を塗り付けておくことが好ましい。また、壁面１は、例えば、超高圧水洗浄法やＭＣＲ工法などにより凹凸のある状態に下地処理をしておくことが好ましい。   Next, the mask material 3 is removed (FIG. 3B), and the unit tile 10 is attached to the wall surface 1 as shown in FIG. At that time, it is preferable to apply the mortar 30 to the wall surface 1 as shown in FIG. Moreover, it is preferable that the wall surface 1 is ground-treated in an uneven state by, for example, an ultra-high pressure water cleaning method or an MCR method.

ユニットタイル１０を壁面１に張付ける際、連結部材２０は各タイル１１に事前に接着等されていないため、各タイル１１を支持しているのは大部分が台紙１２であり、一部を裏面１１ｂにある連結部材２０と張付けモルタル３０が負担している。ユニットタイル１０の上端部を把持して上から吊るすようにして図３（ｃ）に示すようにユニットタイル１０を縦向きとし、壁面１へ押圧することで壁面１に張付けることができる。その後、ユニットタイル１０から台紙１２を剥がすことでユニットタイル１０の張付け作業が完了する。   When the unit tile 10 is attached to the wall surface 1, since the connecting member 20 is not bonded to the tiles 11 in advance, most of the tiles 11 are supported by the mount 12, and part of the back surface is the back surface. The connecting member 20 and the tensioning mortar 30 in 11b bear. The unit tile 10 can be attached to the wall surface 1 by holding the upper end portion of the unit tile 10 and suspending it from above as shown in FIG. Thereafter, the mounting operation of the unit tile 10 is completed by peeling the mount 12 from the unit tile 10.

張付けモルタル３０をタイル裏面１１ｂに塗りつけた後の一連の張付け作業自体は、従来のマスク張り又は改良マスク張りと同様であるが、本実施形態の場合、作業完了時点では張付けモルタル３０はフレッシュな状態であるので、各タイル１１は連結部材２０により強固に連結されていない。したがって、壁面１上で各タイル１１の位置を比較的自由にずらすことができ、目地幅の調整を容易に行うことができる。   A series of pasting operations after the pasting mortar 30 is applied to the tile back surface 11b is the same as the conventional masking or the improved masking, but in the case of this embodiment, the pasting mortar 30 is in a fresh state when the operation is completed. Therefore, each tile 11 is not firmly connected by the connecting member 20. Therefore, the position of each tile 11 on the wall surface 1 can be shifted relatively freely, and the joint width can be easily adjusted.

このように本実施形態では、ユニットタイル１０を壁面１に張付ける段階では、タイル１１間を連結部材２０で実質的に連結しないことにより、目地幅の調整を容易に行うことができる。また、従来のように、タイル１１間を連結部材２０で接着するといった事前準備が不要となるので、その手間を削減できる。張付けモルタル３０の硬化が進んでその強度が出た後は、連結部材２０により各タイル１１間が連結された状態となるので、個別タイル１１の剥離による脱落防止を図ることができる。   As described above, in the present embodiment, at the stage of attaching the unit tile 10 to the wall surface 1, the joint width can be easily adjusted by not substantially connecting the tiles 11 with the connecting member 20. Moreover, since the prior preparation which adhere | attaches between the tiles 11 with the connection member 20 conventionally becomes unnecessary, the effort can be reduced. Since the tiles 11 are connected to each other by the connecting member 20 after the hardening mortar 30 is hardened and the strength is increased, it is possible to prevent the individual tiles 11 from falling off due to peeling.

次に、図４を参照して固定具４０の施工手順について説明する。図４（ａ）及び（ｂ）はいずれも縦方向の目地に沿った施工構造の断面図を示している。図３（ｃ）の状態から張付けモルタル３０の強度が出た後、図４（ａ）に示すように、固定具４０を取り付ける目地に、表側からドリル等により連結部材２０、張付けモルタル３０を通過して壁面１に至る取付孔５を穿孔する。取付孔５は、ドリル等で形成できることから、タイル１１を破損させることがない。取付孔５を穿設する部位（固定具４０の取付部位）は、縦方向の目地と、横方向の目地との交差部分が各タイルの角にアールがあることから、目地幅が広くなっているので望ましい。   Next, the construction procedure of the fixture 40 will be described with reference to FIG. 4A and 4B show cross-sectional views of the construction structure along the joint in the vertical direction. After the strength of the tension mortar 30 comes out from the state of FIG. 3 (c), as shown in FIG. 4 (a), the connecting member 20 and the tension mortar 30 are passed from the front side by a drill or the like to the joint where the fixture 40 is attached. Then, the mounting hole 5 reaching the wall surface 1 is drilled. Since the attachment hole 5 can be formed by a drill or the like, the tile 11 is not damaged. The part where the attachment hole 5 is drilled (the attachment part of the fixture 40) has a wide joint width because the intersection of the vertical joint and the horizontal joint is rounded at the corners of each tile. This is desirable.

取付孔５を穿設すると、固定具４０を取付孔５に挿入する。本実施形態の場合、固定具４０はＬ字型の金具であり、その一辺部分を取付孔５に挿入する。固定具４０の他辺部分は目地に沿わせて配置する。挿入の際には、取付孔５の内面或いは固定具４０のいずれか一方にエポキシ樹脂等の接着剤６を付着させておき、接着剤６の硬化により固定具４０を取付孔５に固定できる。これにより固定具４０が壁面１に接続される。   When the attachment hole 5 is formed, the fixture 40 is inserted into the attachment hole 5. In this embodiment, the fixture 40 is an L-shaped metal fitting, and one side portion thereof is inserted into the attachment hole 5. The other side portion of the fixture 40 is arranged along the joint. At the time of insertion, the adhesive 6 such as an epoxy resin is attached to either the inner surface of the mounting hole 5 or the fixing tool 40, and the fixing tool 40 can be fixed to the mounting hole 5 by curing the adhesive 6. As a result, the fixture 40 is connected to the wall surface 1.

その後、目地に目地モルタル等の目地材７を充填する（図４（ｂ））。目地材７の充填は、例えば、目地材７をタイル１１の表面側から目地にすり込むようにして行う。目地材７の締まりを見計らってスポンジ等によりタイル１１の表面に残った目地材を取り除いて施工が完了する。固定具４０は目地材７に略埋没するので目立たず、美観を害しない。   Thereafter, the joint material 7 such as joint mortar is filled in the joint (FIG. 4B). The filling of the joint material 7 is performed, for example, by rubbing the joint material 7 from the surface side of the tile 11 into the joint. As soon as the joint material 7 is tightened, the joint material remaining on the surface of the tile 11 is removed with a sponge or the like to complete the construction. Since the fixture 40 is substantially buried in the joint material 7, it is not conspicuous and does not impair the beauty.

本実施形態では、固定具４０及び連結部材２０を介して各タイル１１が機械的に壁面１に固定されることから、その剥離防止性能を更に向上できる。なお、固定具４０の数は多い程、脱落防止性能が向上するが、本実施形態のように１つのユニットタイル１０に対して２つ程度で十分である。   In the present embodiment, since each tile 11 is mechanically fixed to the wall surface 1 via the fixture 40 and the connecting member 20, the anti-peeling performance can be further improved. Note that the greater the number of fixtures 40, the better the drop-off prevention performance. However, about two are sufficient for one unit tile 10 as in this embodiment.

また、本実施形態では固定具４０としてＬ字型の金具を利用したが、その形状としては種々の形状のものを採用でき、また、その表面には凹凸を設けることで壁面１等への付着性を高めてもよい。更に、固定具４０の取付方法も、取付孔５及び接着剤６による方法以外に、ねじ込み式なども採用可能である。   In the present embodiment, an L-shaped metal fitting is used as the fixture 40. However, various shapes can be adopted, and the surface can be attached to the wall surface 1 by providing irregularities. You may increase the nature. Further, as a method for attaching the fixture 40, a screw-in type or the like can be employed in addition to the method using the attachment hole 5 and the adhesive 6.

＜まとめ＞
現場でユニットタイルを張付ける方法（手張り工法）は、モザイクタイル張りが圧倒的に多く、マスク張り、改良マスク張りも信頼性の高い方法とされ、それなりに採用されているが、まれには密着張り（ヴィブラート工法）が採用される。タイル張り工法は、対象建物の条件、下地の精度、効率性、接着の信頼性が密接に絡んでおり、現在ではそれなりに洗練されてきているといえる。 <Summary>
The method of attaching unit tiles on site (hand-clad construction method) is overwhelmingly mosaic tiled, and masking and improved masking are also considered to be reliable methods, but they are used as such, but in rare cases Adhesion tension (Vibrato method) is adopted. The tiling method is closely related to the conditions of the target building, the accuracy of the groundwork, the efficiency, and the reliability of bonding, and it can be said that it has been refined as such.

工法の信頼性が確立するのは、実際に使用し始めてから経年劣化等で剥離、剥落が生じる程度が分かる期間、おおよそ１０年程度の長期間を必要とする。例えば、密着張りは、ユニットタイルではあまり採用されないが、電動振動工具を用いて叩き締めることから、タイルの裏面にモルタルが廻りやすいこと、施工効率がよく初期の付着強度が高いので、開発された直後から二丁掛けタイルの張付け工法として急速に広まった。   Establishing the reliability of the construction method requires a long period of about 10 years, a period in which the degree of peeling or peeling due to aging or the like is known after actual use. For example, adhesion is not often used for unit tiles, but because it is tightened with an electric vibration tool, mortar easily turns around the back of the tile, and it has been developed because it has high construction efficiency and high initial adhesion strength. Immediately after that, it spread rapidly as a method of attaching two-cable tiles.

しかし、施工速度を上げすぎたりした管理不足による問題以外にも、きちんと管理されていても剥離・剥落しやすい傾向があることがしばらくしてから分かってきた。密着張りではタイルは強く接着するが同時にタイルを剥がそうとする元応力も大きくなることが経年劣化で剥がれやすい原因であることが分かった。   However, it has been known for some time that there is a tendency to peel and peel off even if it is properly managed, other than problems caused by insufficient management such as increasing the construction speed too much. It was found that the tiles strongly adhere to each other, but the original stress to peel off the tiles at the same time increases, which is a cause of easy peeling due to aging.

このように、従来のタイルの張り方を変えるというのは、リスクを伴う場合があり、概して変更を嫌う傾向がある。   Thus, changing the way tiles are laid out in the past can be risky and generally tends to dislike changes.

本発明は、従来行われていた、連結部材を事前にユニットタイルに接着するという工程を無くすという点で従来の工法を大きく変更しており、その創作過程においては種々の検討が必要であった。例えば、
○足場およびその近傍で作業スペースを確保できるか、
○連結部材が現場でユニットタイル上に載置される際、風で飛ばされる等して作業性を害しないか、
○ユニットタイルを壁面に張付ける際の作業性（台紙の貼られた側を内側にして多角形状に反りを生じることから、張付けモルタルの付着後のユニットタイルを張付ける場所まで移動する間に振動等により、モルタル等の位置ずれを生じるのかどうか等）、
○叩き締めるときに連結部材の一部がはねたり、各タイルが動く等してタイルの接着性に影響を与えないか、
○張付けモルタルの面積や量、
