[1] An embodiment of the present invention will be described with reference to the drawings.

(1) FIGS. 1 to 8 relate to a lath complex as an example of an embodiment of the present invention.

In the lath complex A, four surface force bones F, lath material L, ten flexible strips S, five back force bones B, and a sheet-shaped waterproof material W are arranged from the front side to the back side. They are overlapped in the front and back directions in this order, and can be used by being fixed to a wooden panel as a base material P on the back side, for example.

(2) The lath material L is a vertically long rectangular shape having a rhombic mesh H (32 mm in the major axis direction and 16 mm in the minor axis direction at the distance between the centers of the intersections of the linear portions constituting the mesh H) used as a base for mortar coating. It is a flat lath.

(3) The sheet-shaped waterproof material W is made of vertically long rectangular tarpaulin paper and is arranged on the back side of the mortar-coated body on the mortar-coated wall to prevent moisture penetration from the mortar-coated body. .. As shown in FIGS. 1 and 2, the lath material L and the sheet-shaped waterproof material W are overlapped with each other by shifting the amount corresponding to the stacking allowance in the vertical and horizontal directions in preparation for the case where the lath composite A is arranged adjacently. There is.

(4) The axial direction of the surface force bone F is the vertical direction, and four bones F are arranged parallel to each other on the front side of the lath material L at equal intervals in the horizontal direction.

On the other hand, the back force bone B has an axial direction in the horizontal direction, five of which are parallel to each other at equal intervals in the vertical direction, and a flexible strip S is provided between the lath material L and the lath material L on the back side. It is arranged by sandwiching it.

The surface force bone F and the back force bone B are the same steel wire rod (1.6 mm diameter) having higher rigidity and strength than the linear portion (about 0.8 × 1 mm) constituting the flat lath which is the lath material L. Consists of. The surface force bone F and the back force bone B are linear as a whole, are parallel to the surface composed of the lath material L, and are welded to the lath material L in a state where they intersect each other at about 90 degrees. ..

(5) The flexible strip S has an axial direction in the vertical direction and is parallel to the surface force bone F at a position where it does not overlap with the surface force bone F, and is at equal intervals in the lateral direction (back force bone B). Ten of them are arranged parallel to each other at intervals of about one-third of each other. The flexible strip S is a round cord-shaped flexible strip having a substantially circular or substantially elliptical cross section or a jute hemp cord having a similar shape. The flexible strip S is thicker than the front force bone F and the back force bone B (about 3 mm in diameter), and the front-back direction dimension (about 3 mm) in the lath complex A is larger than the back force bone B in the front-back direction. The width (about 3 mm) in the orthogonal direction is about one-fifth of the width of the mesh H of the lath material L.

(6) The front side surface of the sheet-shaped waterproof material W is joined to the back side portion of the flexible strip S by an adhesive.

The flexible strip S is substantially along the back side of the lath material L as a whole, and the portion intersecting the back force bone B is a schematic enlarged vertical sectional view of a main part along the central axis of the flexible strip S. As shown in FIG. 8, the mesh H of the lath material L bulges toward the front side of the lath material L, but the width of the flexible strip S in the direction orthogonal to the front and back directions is the mesh of the lath material L. Since it is sufficiently smaller than H, it does not hinder the proper formation of the mortar coating layer by coating the mortar from the front side of the lath material L.

The back side of the lath material L and the front side surface of the sheet-shaped waterproof material W are separated from each other in the front and back directions with a flexible strip S sandwiched by a dimension that greatly exceeds the diameter of the back force bone B.

(7) By applying mortar as a coating material from the front side of the lath material L in the lath composite A fixed to the wooden panel as the base material P on the back side, the front side of the sheet-shaped waterproof material W is exposed to the front side. When forming the coating layer M in which the force bone F, the lath material L, the flexible strip S and the back force bone B are embedded, as shown in FIGS. 7 and 8, the thickness direction of the coating layer M It is easy to apply the mortar so that the lath material L is located in the middle portion of the material.

The back side of the lath material L is surely supported so as to be separated from the front side surface of the sheet-shaped waterproof material W so as to sandwich the dimension of the flexible strip S whose front and back direction dimensions are larger than those of the back force bone B. Therefore, it is possible to more easily coat the mortar so that the lath material L is located in the middle portion in the thickness direction of the coating layer M (it does not need to be in the center position in the thickness direction). ..

Further, since the back side portion of the cross section of the flexible strip S has a convex shape (curved convex surface shape) toward the back side, the convex portion of the back side portion of the flexible strip S in the coating layer M. Mortar is also present between both sides and the front side surface of the sheet-shaped waterproof material W.
