ス等のラス材を釘やステラプルで部分的に封着、固定し

Conventionally, mortar walls are made by applying waterproof paper, such as tar felt, to the base material of the main board, and then partially sealing and fixing lath materials such as wire lath or metal lath with nails or Stella pulls, and then applying mortar material. It was formed by applying it to lath material.

しかしながら、このようにして形成されたモルタル壁は
経時的にモルタルの自重あるいは外部からの振動により
部分的に固定されたラス材がその網目を変形しつつ引下
げられるために、その網目をとりまくモルタル部分にひ
び割れや剥離を生じさせることが多々あった。
However, the mortar wall formed in this way is pulled down over time due to the mortar's own weight or vibration from the outside, causing the partially fixed lath material to deform its mesh and pull down, resulting in the mortar surrounding the mesh being pulled down. This often caused cracks and peeling.

換言すれば、これは防水紙上に貼ったラス材の突出が小
さく、モルタル材との物理的結合が弱いため大きいモル
タルの自重によって引下げられたりするためである。
In other words, this is because the protrusion of the lath material pasted on the waterproof paper is small and the physical bond with the mortar material is weak, so it may be pulled down by the weight of the large mortar material.

また従来、モルタル壁は前記した工程を順々に施うたぬ
に工期が長期化し、経済的不利も免れなかった。
Furthermore, in the past, mortar walls had to undergo the above-mentioned processes one after another, which resulted in a long construction period and an economic disadvantage.

However, recently, with the aim of shortening the construction period, reducing cracks, and saving materials, for example, a mixture of plywood, cement, and waterproof adhesive has been formed into a single piece with an uneven shape.
Solidified base materials are becoming commercially available.

この下地板は木ずり、ラス材、防水紙を一体化したため

This base board is characterized by a significant improvement in shortening the construction period because it integrates lumber, lath wood, and waterproof paper.

However, this base plate has the function of reducing vibrations as mentioned above, and provides insulation, as well as condensation and other moisture, especially deformation of the plywood caused by condensation between the inner and outer walls, and moisture passing through the plywood. There was a disadvantage in that no effective structure was provided for cracks caused by the differential expansion and contraction of the mortar.
