入により、ヒビ割れの発生を防止する。The mortar is well-touched with an adhesive, a water-retaining agent allows for a long open time, and the inclusion of crushed asbestos prevents cracks from forming.
以下、この発明の詳細な説明する。 The present invention will be explained in detail below.
混和剤は、粉砕アスベスト等の各種粉砕繊維に、石膏プ
ラスター上塗用、寒水、顔料、接着剤、保水剤を混合し
て形成され、繊維に対する各混合物の好ましい混合量を
表１に示す。The admixture is formed by mixing various types of pulverized fibers such as pulverized asbestos with gypsum plaster top coat, cold water, pigment, adhesive, and water retention agent. Table 1 shows the preferable amounts of each mixture to be mixed with the fibers.
なお、繊維に粉砕アスベストを用いた場合、長い繊維０
．７ Ｋｇに対し、細かい繊維を０．３ Ｋｐの割合で
混合して使用すると共に、石膏プラスターは増量材とな

てはＭＣを挙げることができる。In addition, when using crushed asbestos for fibers, long fibers are 0.
．． Fine fibers are mixed at a ratio of 0.3 Kp to 7 Kg, gypsum plaster is used as an extender, Popal (PVA) is used as an adhesive, and MC is used as a water retention agent.
また、繊維としては粉砕アスベストに代え、各種合成繊
維や人造繊維、紙繊維、動物繊維を使用することができ
る。Moreover, as the fiber, instead of crushed asbestos, various synthetic fibers, man-made fibers, paper fibers, and animal fibers can be used.
表 １
上記混和剤は、川砂や珪砂及び水と共にセメントに混合
し、これを練り上げることによりモルタルを形成する。Table 1 The above admixture is mixed with cement together with river sand, silica sand, and water, and the mixture is kneaded to form mortar.
このモルタルは、セメントに対して、混和剤、川砂や珪
砂、水の混合量を選ぶことにより、使用目的に応じた状
態に形成され、表２は各種モルタルのセメントに対する
混合量を示している。This mortar is formed in a state according to the purpose of use by selecting the amount of admixture, river sand, silica sand, and water mixed with the cement, and Table 2 shows the amount of each mortar mixed with the cement.
表 ２ 次に、上記モルタルを使用した施工例を示す。Table 2 Next, an example of construction using the above mortar will be shown.
（一般タイルの貼付施工の場合）
タイル貼付用に練り上げたモルタルをタイル貼付面に３
〜５朋厚で塗布する。このとき、４０〜６０分の間にタ
イルが貼り終ると予想できる面積を塗工し、櫛目を入れ
た後、追っかけてタイルを貼って行く。(In case of pasting general tiles) Apply mortar prepared for tile pasting to the tile pasting surface for 3 minutes.
Apply at a thickness of ~5 mm. At this time, the area where the tiles can be expected to be finished being applied within 40 to 60 minutes is coated, a comb pattern is made, and tiles are subsequently applied.
タイル貼付時、タイルをたたき込むと、モルタルの粘り
によって喰込みがよく、タイルとモルタルの間に隙間の
発生がなく、タイルを強固に固定化することができる。When attaching tiles, when the tiles are hammered in, the viscosity of the mortar allows for good penetration, and there is no gap between the tiles and the mortar, allowing the tiles to be firmly fixed.
（モルタルの一発仕上げをする場合）
モルタル仕上げ用に練り上げたモルタルを適当な厚さに
なるよう、コテ圧を加えて塗り、はどなく仕上げの押え
をする。(When performing a one-shot finish with mortar) Apply the mortar that has been kneaded for mortar finishing to an appropriate thickness with a trowel, and press the finish firmly.
なお、タイル貼付は及びモルタル−発仕上げの下地がＡ
ＬＣの場合、吸水が激しいため、ＡＬＣの表面に事前に
プライマーを塗布し、このプライマーが良く乾燥した後
、モルタルを塗るようにする。In addition, when attaching tiles, the base material for mortar finishing is A.
In the case of LC, water absorption is intense, so a primer is applied to the surface of ALC in advance, and after this primer has dried thoroughly, mortar is applied.
（重量物の圧雪）
重量物の圧雪用に線上げたモルタルを下地壁面に５〜６
鳳厚となるよう塗布し、その表面に櫛目を入れると共に
、重量物の貼付面にもモルタルを薄く塗り、この状態で
重量物を壁面にねじ込むように押付ければよく、モルタ
ルを介して壁面に重量物が貼付けられる。(Heavy load snow compaction) 5 to 6 pieces of mortar lined up for heavy load snow compaction on the base wall surface.
Apply a thick layer of mortar, make combs on the surface, and apply a thin layer of mortar to the surface to which the heavy object will be attached.In this state, press the heavy object as if screwing it into the wall. Heavy objects are attached.
ちなみに、重量物貼付用のモルタルは、１イで１５０即
の静荷重に耐える接着力が得られる。By the way, mortar for attaching heavy objects can provide adhesive strength that can withstand a static load of 150 mm in 1 step.
以上のように、この発明によると、粉砕アスベスト等の
繊維に、接着剤と保水剤を混合したので、セメントへの
混合により、モルタル乾燥後における繊維の自己加強と
接着剤の作用でモルタルの接着性が大幅に向上し、一般
タイルの貼付けだけでなく、垂直壁面への重量物の固定
も可能になる。As described above, according to the present invention, since the adhesive and water retention agent are mixed with fibers such as crushed asbestos, by mixing with cement, the self-strengthening of the fibers after drying of the mortar and the action of the adhesive cause the mortar to adhere. This greatly improves performance, making it possible not only to attach regular tiles, but also to fix heavy objects to vertical walls.
また、繊維の混入により、モルタルの延びが良くなり、
塗布作業が容易に行なえると共に、ヒビ割れの発生がな
く、床面や壁面のモルタ−発仕上げが可能になる。In addition, the mixing of fibers improves the elongation of mortar,
The application work can be easily performed, and cracks do not occur, making it possible to finish floors and walls with mortar.
更に繊維と接着剤の作用により、完全防水モルタルを作
成することができる。Furthermore, the action of the fibers and adhesive makes it possible to create a completely waterproof mortar.
