Description

[Detailed Description of the Invention] This invention relates to a wall joint (hereinafter referred to as a wall joint) with a peeling film that divides the external wall surface neatly and prevents cracks in the wall surface when finishing the exterior of a wooden building with mortar.

Traditionally, as this type of wall joint, what is called a groove joint made from synthetic resin has been often used, but when finishing with mortar coating, mortar enters the joint groove, so in order to remove it. The drawback was that it required wiping with water, which took time and effort.

This invention solves the above-mentioned drawbacks, and its main structure is that a mounting board is formed in the longitudinal direction of the wall joint, and that the mounting board has raised uprights facing opposite to each other on the surface side. A strip is provided to form a channel-like groove. A release coating such as masking tape is applied to the entire inner circumferential wall of this joint groove. Therefore, even if the finishing mortar enters the joint groove, by peeling off the release film, the inside of the groove can be finished very neatly, and the division of the outer wall surface can be made aesthetically pleasing.

Next, an embodiment of this invention will be described with reference to the drawings.A wall joint 1, which is formed into a longitudinal bar shape even when a synthetic resin is extruded, has a strip-shaped substrate 2 formed on its mounting side. On the surface side of this substrate 2, upstanding strips 3, 3 are provided protrudingly opposed to each other at a predetermined interval in the longitudinal direction to form a channel-shaped joint groove 4. A release coating 5 such as masking tape, for example, is applied to the entire inner peripheral wall of the joint groove 4. Furthermore, the upright strips 3, 3 are integrally formed with barbed protrusions 6, 6 on the outside of their tips. 7 shows finishing mortar, and 8 shows the base ground of the outer wall of the wooden building.

This device has the above-mentioned configuration, and to explain how to use it now, the wall joint 1 is fixed to the joint part of the base surface 8 with adhesive or mortar balls, etc., and the surface of the base surface 8 is Finishing is done by applying finishing mortar 7 to the flat surface up to the height of the upright strips 3, 3. Thereafter, when the mortar on the wall surface is dry, the peeling film 5 is removed by pulling or the like, and the joint grooves 4 are exposed and finished neatly as shown in FIG. Further, FIG. 4 shows an embodiment in which the upright strips 3, 3 are each inclined inward.

As explained above, by attaching the stripped wall joint of this invention to the external wall surface of a wooden building and using it as a wall joint, a beautiful sectioned groove can be constructed with ease and extremely reliably. This eliminates the need to wash away mortar that has entered the joint groove during construction, and has practical effects such as greatly shortening construction time.
Furthermore, since the wall joints are made of synthetic resin, they can be easily molded and mass-produced, and the wall joints themselves are made extremely strong by the substrate provided in the longitudinal direction, so there is no fear of cracks or the like. effective. In addition, channel-like grooves formed by opposing upstanding strips provided on the surface of the substrate have the effect of preventing the finishing mortar from splitting, cracking, etc., and preventing moisture from forming. It has the effect of preventing water from entering the interior and also fully fulfilling the role of a water stop plate.
Furthermore, since a release coating such as masking tape is applied to the entire inner circumferential wall of the joint groove, mortar that has entered the joint groove is attached to the release coating and is removed when the release coating is peeled off, leaving no residue in the joint groove. It has the excellent effect of leaving the grooves neatly finished.

[Brief explanation of the drawing]

The drawings show an embodiment of this invention; Fig. 1 is a slope view showing wall joints of this invention, Fig. 2 is a cross-sectional view of the wall joints installed and coated with mortar, and Fig. 3 is a cross-sectional view of the wall joints with mortar applied. FIG. 4 is a sectional view showing another embodiment of the upright strip. Reference numeral 1 is a wall joint, 2 is a substrate, 3 is an upright strip, 4 is a joint groove, 5 is a release coating, 6 is a protrusion with bite, 7 is mortar, and 8 is concrete.
