DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a mortar wall base material used for mortar wall construction of a building.

[0002]

2. Description of the Related Art Various structures have been developed and put to practical use for mortar wall base materials usually used for mortar wall construction of buildings. As shown in FIGS. 4A and 4B, for example, the conventional mortar wall base material has a front surface paper 1 in which oblong slit holes 2 are arranged in a horizontal line, and a staggered arrangement in adjacent rows, and waterproofness. A horizontal iron wire group 4 is sandwiched between the heat-insulating backing paper 3 in parallel with each other along the rows of the slit holes 2, and a vertical iron wire group 5 is provided outside the top paper 1 with the horizontal iron wire 5. The two iron wire groups 4 and 5 are vertically arranged so as to intersect at a substantially right angle with the group 4, and the intersection at the position of the slit hole 2 is welded to form a mesh. The vertical iron wire group 5 has a valley 5 ′ at every third intersection with the horizontal iron wire group 4.
Is formed (see FIG. 4B), and a swelling (gap) is secured between the top paper 1 and the back paper 3 by the depth of the valley 5 ′,
The applied mortar is configured to form a stable mortar thickness.

[0003] However, in the conventional mortar wall base material, the front paper 1 and the back paper 3 are bonded to each other by providing a glued surface 6 in a band shape at an appropriate position avoiding the slit hole 2 (FIG. 4).
A, B).

[0004]

In the mortar wall base material described above, the gluing of the top paper 1 and the back paper 3 is performed at an appropriate position avoiding the slit holes 2, and therefore the following problems are caused. there were. When the space between the gluing surfaces 6 is close, the front paper 1 and the back paper 3
Are adhered in a dark manner, and a sufficient swelling (gap) between the front paper 1 and the back paper 3 cannot be obtained, so that the adhesion amount of the applied mortar is necessarily limited. Therefore, the mortar does not sufficiently wrap around the horizontal iron wire group 4 located between the front paper 1 and the back paper 3, and the adhesion between the horizontal iron wire group 4 and the mortar is poor, and a stable and good mortar wall is constructed. It was difficult to do. If the space between the glued surfaces 6 is small, the adhesive strength between the top paper and the back paper is insufficient, and there is a problem that a so-called waist-folding phenomenon occurs in which the mortar is deformed by the pressure at the time of applying the mortar.

Therefore, an object of the present invention is to eliminate all of the above problems, and to provide a front paper and a back paper,
Glue in parallel strips only at the positions on both sides of the valleys of the vertical iron wire group. (I) A bulge that mortar easily enters between the front paper and the back paper is secured, and the horizontal iron wire group and the mortar Improving the adhesion, enabling stable and good mortar wall construction, and (II) increasing strength against waist breaks,
An object of the present invention is to provide a mortar wall base material that is excellent in workability and contributes to stable and favorable mortar wall work.

[0006]

As a means for solving the above-mentioned problems of the prior art, a mortar wall base material according to the first aspect of the present invention comprises a front paper 1 having a plurality of slits 2 and a back paper 3. A vertical iron wire group 5 is disposed outside the surface paper 1 so as to intersect the horizontal iron wire group 4, and the vertical and horizontal iron wire groups 5 and 4 A mortar wall base material in which the intersections at the positions of the holes 2 are welded to form a mesh, wherein the vertical iron wire group 5 has valleys at two or more intersections with the horizontal iron wire group 4. 5 ′ is formed, and the front paper 1 and the back paper 3 are glued in parallel strips only at positions on both sides of the vertical iron wire group 5 that sandwich the valley 5 ′. Features.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of a mortar wall base material according to the present invention is shown in FIGS. Horizontally elongated oval slit holes 2 form a line on the horizontal line, and the upper and lower rows have a horizontal iron wire group 4 between the front paper 1 and the back paper 3 which are opened in a staggered arrangement. Each is sandwiched in parallel along the position of the slit hole 2. A group of vertical iron wires 5 is arranged vertically outside the front paper 1 so as to intersect the group of horizontal iron wires 4 at a substantially right angle, and the groups of vertical and horizontal iron wires 5 and 4 are located at the positions of the slit holes 2. Intersections are spot-welded to form a mesh. In the vertical iron wire group 5, every two intersections with the horizontal iron wire group 4 (however, two or more intersections are possible)
A substantially V-shaped valley portion 5 'is formed in FIG. Therefore, the two horizontal iron wire groups 4 and 4 between the valleys 5 ′ and 5 ′ form a mesh in a form floating from the back paper 3.
Inevitably, the front paper 1 along the iron wire group 4 is also partially lifted from the back paper 3 to secure a swelling (gap) between the front paper 1 and the back paper 3 so that the applied mortar has a stable mortar thickness. It is configured to be realized. The valley 5 ′ of the vertical iron wire group 5 is preferably used in a shape protruding about 10 mm to the top.

The front paper 1 and the back paper 3 are glued 6 in a parallel belt shape only at positions on both sides of the valley 5 ′ of the vertical iron wire group 5. Therefore, a sufficient swelling (gap) can be ensured between the front paper 1 and the back paper 3 in the portion A (non-glued portion) shown in FIGS. 1 and 3, and the applied mortar is applied to the horizontal iron wire group 4. Sufficient wrapping is obtained, and the degree of adhesion between the horizontal iron wire group 4 and the mortar is obtained favorably, enabling stable and favorable mortar wall construction. On the other hand, since the positions sandwiching the valleys 5 ′ of the vertical iron wire group 5 are glued in a band shape, the front paper 1 and the back paper 3 are sufficiently firmly joined to each other, and the vertical and horizontal iron wire groups 5 and 4 are joined together. With the so-called three-material combination effect, the buckling strength is increased, and a stable mortar application operation can be realized.
Enables stable and good mortar wall construction.

The mortar wall base material is 710 × 188
The size is about 0 to 2040 mm. The horizontal iron wire group 4
Are arranged at intervals of about 50 mm, and the vertical iron wire group 5
Are arranged at intervals of about 40 mm. The horizontal iron wire group 4 and the vertical iron wire group 5 both have an outer diameter of 1.6 mm or 2.3 mm.
mm zinc-iron wire is preferably used. This is for preventing corrosion and preventing the mortar wall from peeling off for a long time.

The front paper 1 has liner paper or kraft paper, and the back paper 3 has waterproof and heat insulating properties.
For example, tarpaulin paper or the like is preferably used. The shape of the slit hole 2 is not limited to an elliptical shape, and a circular shape is suitably implemented. The slit holes 2 may be provided regularly in the horizontal and vertical directions.

[0011]

According to the mortar wall base material of the present invention, the front paper and the back paper are glued in a parallel belt shape only at the positions on both sides sandwiching the valley of the vertical iron wire group. . The swelling (gap) between the front paper and the back paper can be sufficiently ensured, and the applied mortar can sufficiently wrap around the horizontal iron wire group, thereby improving the adhesion between the horizontal iron wire group and the mortar, Enables stable and good mortar wall construction. 2. The front and back papers are bonded sufficiently firmly,
The so-called three materials combined with the horizontal iron wire group can increase the strength of the buckling, so that a stable mortar painting operation can be realized and a stable and favorable mortar wall can be constructed.
