Abstract

PROBLEM TO BE SOLVED: To increase adhesive strength to a lath of mortar, and to equalize and thicken coating thickness in the preparation of a mortar wall. SOLUTION: A plurality of rows of projecting section 2 groups projected and formed continuously in the same direction on the same lines are formed in mutual parallel on a flat lath while the intervals of the rows of the projecting section groups are kept within a range from two stages to five stage when an intersection 1 group on a straight line parallel with a straight line is used as one stage. When the projecting section groups are applied and installed to a foundation board, adhesive strength to the lath of mortar is increased and mortar is applied thickly and uniformly, and the strength of a wall is augmented. Since a plane section is floated from the foundation board, the lath has elasticity and is easy to be applied.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lath used as a base when painting a mortar wall of wooden construction.

[0002]

2. Description of the Related Art Various laths such as rib laths and metal laths are used as a base for coating a wall of a mortar wall, but wire laths which are inexpensive, light and easy to handle are often used. Of these wire laths, flat laths are generally used, but flat laths have a drawback in that it is difficult to make the wall thick, and therefore the wall has low strength and is easily peeled off.

Therefore, cobras and corrugated laths, which are improved flat laths, have been developed. The cobra is formed by projecting wire intersections of a flat lath at regular intervals in the vertical and horizontal directions, and the corrugated lath is formed by continuously forming a wavy shape.

However, both of them have a large outer diameter of 1.2 mm in order to maintain the shape, and are therefore expensive.

[0005]

The problem to be solved by the present invention is to increase the adhesive strength of the mortar to the lath to uniformly coat the mortar.

[0006]

The present invention has a flat lath,
When a plurality of rows of projecting portions formed continuously on the same straight line and projecting in the same direction are provided in parallel with each other, and a group of intersections on a straight line parallel to the straight line is one stage, a row of projecting portion groups The feature is that the interval of is set in the range of 2 to 5 steps.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, FIG. 5 shows a flat lath. Reference numeral 1 is an intersection when wires are continuously formed in a diamond shape, and adjacent intersections are on the same straight line in the vertical direction (vertical direction), the horizontal direction (horizontal direction), and the diagonal direction. The flat lath is usually formed in a rectangular shape having a length longer than the width, and is attached to the base plate with the length in the vertical direction. This flat lath has a cross section of 1
Square wires each having a side of about 0.6 mm are continuously joined in a rhombus, and the rhombus has a major axis of about 30 mm and a minor axis of about 20 mm.

In the embodiment shown in FIG. 1, intersections 1 on the same straight line in the vertical direction of the flat lath are projected in the same direction, and projecting portions 2 are continuously formed in one row. When the intersection 1 on the same straight line in the vertical direction is one step, the protruding portions 2 are continuously provided in one row in the vertical direction at intervals of every fourth step, that is, three steps.

The height H of the protrusion 2 can be appropriately selected within the range of 2 to 10 mm depending on the size of the diamond, the material and thickness of the wire, and the thickness of the coating, but as shown in FIG. Two
Is about 7 mm when the pitch P (substantially equal to the vertical interval between adjacent intersections 1 on the same stage) is 30 mm.
Similarly, the arrangement of the protrusions 2 may be arbitrary depending on the size of the rhombus, the material and the thickness of the wire, but it is difficult to spread the wire lath on the flat surface at every second step, and at every seventh step or more. Then, similar to the flat lath mentioned above, the drawback that it cannot be applied thickly appears.

In the lath of the present invention, as shown in FIGS. 2 and 3, a group of protrusions 2 are attached to the base plate 11 to be attached to apply mortar. The plane portion 3 is separated from the base plate 11 by a height H of the protrusion 2. Further, the projecting portion 2 can provide a proper elasticity to the entire lath.

In the embodiment shown in FIG. 4, the protrusions 2 are continuously formed in one line on the same straight line for every fourth step inclined with respect to the long side. In FIG. 4, the inclination of the group of protrusions 2 is downward to the left, but this may be downward to the right. Further, although not shown, when a wide plate called a control panel is used instead of the base plate 11, the projecting portions 2 can be provided in the lateral direction.

The lath provided with the protrusions 2 at each of the plurality of stages can be easily manufactured from a commercially available flat lath. For example, two rolls are installed at a predetermined interval, one roll has a ridge having a triangular section, and the other roll has a groove at a position facing the ridge. A flat lath may be inserted between the rolls which are provided and rotate in opposite directions. When the group of protrusions 2 is provided in the vertical or horizontal direction, the ridges and grooves are provided on the same circumference, and when the group of protrusions 2 is provided at an inclination, the ridges and grooves are provided on the roll shaft. It is preferable to incline it.

The lath according to the present invention is not limited to the continuous rhombus, but may have any shape such as a quadrangle or a hexagon, and the wire forming the lath may have any cross-sectional shape such as a circle. Further, it is possible to provide the protrusion 2 at another portion without providing it at the intersection 1, but it is preferable to provide it at the intersection 1 in view of the strength of the protrusion 2.

[0014]

EFFECTS OF THE INVENTION Since the protrusions are continuously provided in a row for each of a plurality of stages, if the protrusions are attached to the base plate, the adhesive strength of the mortar to the lath is increased and the mortar is attached. Since it can be applied thickly, the strength of the mortar wall is increased. For example, a mixture of 1 bale of styrofoam particles and 1 bale of mortar can be applied to a mortar wall of less than 4 tsubo in a flat lath, but only 3 tsubo in a lath of the present invention. That is, the coating thickness becomes thicker than when a flat lath is used.

Further, since the flat portion is floated from the base plate, the lath has elasticity to easily apply the mortar.

Since a commercially available flat lath having a thin wire can be processed and easily manufactured, it can be provided at a low cost.
