Description

[Detailed description of the invention] (Industrial application field) This invention is a joint for mortar flat walls that is embedded in the wall to maintain a constant coating thickness and prevent wall cracks when forming mortar flat walls of houses. Regarding parts.

(Prior art) Making the coating thickness of flat mortar walls of houses constant,
In order to prevent cracks in mortar flat walls,
As shown in Figure 1, a joint member 1 made of synthetic resin consists of a partition plate 1b of a constant height that projects vertically from the center of an elongated rectangular bottom plate 1a that comes into contact with the surface of the base material.
Or, as shown in Fig. 12, a synthetic resin consisting of two partition plates 2b and 2c at a constant height and a constant interval and an intermediate connecting plate 2d protruding perpendicularly from an elongated rectangular bottom plate 2a that contacts the surface of the base material. joint material 2
was placed at a predetermined position on the upper surface of the base material 3, and mortar was applied to the upper ends of the joint members 1 and 2 to form a mortar plane wall 4.However, a fire broke out outside and the flames spread to the mortar. When it hits the flat wall 4, the partition plate 1b burns in the case of the joint member 1, and the intermediate connecting plate 2d burns in the case of the joint member 2, and the flames reach the base material 3, causing the fire to spread throughout the house. The point was hot.

(Purpose) The purpose of the present invention is to make the flame reach the base material more slowly than before when the joint material burns.

(Structure) In order to achieve the above object, the present invention is characterized in that a rectangular upper vertical plate, an intermediate inclined plate, and a lower horizontal plate are integrally connected.

A detailed explanation will be given below based on each embodiment shown in FIGS. 1 to 10. FIG. 1 shows a first embodiment, in which a mortar flat wall joint member 10 is formed by integrally connecting an elongated rectangular upper vertical plate 10a, intermediate inclined plate 10b, and lower horizontal plate 10c. Figure 2 shows a second embodiment of the elongated rectangular upper vertical plate 1.
A mortar flat wall joint member 11 is formed by integrally connecting the doglegged intermediate inclined plate 11b and the lower horizontal plate 11c. FIG. 3 shows a third embodiment, which includes an elongated rectangular upper vertical plate 12a, a middle inclined plate 12b having a plurality of bent parts, and a lower horizontal plate 12.
Joint member 1 for mortar flat wall by integrally connecting c.
2 is formed. FIG. 4 shows a fourth embodiment in which an elongated rectangular horizontal plate 13b is formed at the upper end of an elongated rectangular vertical plate 13a, and the vertical plate 13a, an intermediate inclined plate 13c, and a lower horizontal plate 13d are integrally connected. A mortar flat wall joint member 13 is formed. FIG. 5 shows a fifth embodiment in which an elongated rectangular horizontal plate 14b is attached to the upper end of an elongated rectangular vertical plate 14a.
Furthermore, vertical plates 14c are provided above both sides of the horizontal plate 14b.
14d, and the vertical plate 14a, the intermediate inclined plate 14e, and the lower horizontal plate 14f are integrally connected to form the mortar flat wall joint member 14.
Respective mortar flat wall joint members 10, 11, 1
2, 13, and 14 are arranged at predetermined positions on the base material 3 as shown in FIGS.
upper vertical plates 10a, 11a, 12a, 13a,
A mortar plane wall 15 is formed by applying mortar using the upper end of 14a as a ruler.

The material of the mortar flat wall joint member may be any metal, synthetic resin, cement, etc.

(Effects) According to the present invention, the rectangular upper vertical plate, middle inclined plate, and lower horizontal plate are connected together, so if a fire breaks out outside and the flames hit the mortar flat wall, the vertical plate will Although the flame burns, the flames traveling perpendicular to the mortar flat wall at the intermediate inclined plate are prevented from moving straight, so the flame burns obliquely through the intermediate inclined plate and reaches the base material longer than before. I can do it.

As a result of a class 2 heating test according to the Japanese Industrial Standards (JIS), the temperature of the base material when applying the first example was able to be lowered by about 30°C compared to when applying the conventional product.
