Description

Description: TECHNICAL FIELD The present invention relates to a joint structure of a panel useful for constructing an outer wall and an inner wall of a building or a structure. More specifically, even if the decorative surface width and the panel thickness are increased, the male and female mating structures do not peel off from the wall base, and
The present invention relates to a joint structure of a panel which can be stretched vertically and horizontally and has complete waterproofness.

[Conventional technology]

Conventionally, as shown in FIG. 6, a joint portion of this type of panel is formed by connecting a panel a having a real structure on the back side by a male-female fitting structure, and connecting an end portion of the panel a ₁ to a wall base α. Is fixed by a fixing tool β.

[Problems to be solved by the invention]

However, a gap γ is formed between the panels a ₁ and a ₂ by the head of the fixing tool β, and rainwater or the like blown up from the joint portion b is transmitted to the wall foundation α by the large gap γ, and the wall foundation is formed. There was a disadvantage that α was corroded. Furthermore, since the fixing tool β is formed near the joint portion b, rainwater or the like directly reaches the head of the fixing tool β and the fixing hole formed in the panel a ₁ by the fixing tool β. There were drawbacks such as rusting of the fixture β, infiltration of rainwater into the wall base α from the fixing holes, and flow of wastewater due to rust of the fixing β.

[Means for solving the problem]

According to the present invention, in order to eliminate such drawbacks, the connection on the frame side of the panel has a real structure, the fixing of the panel is performed at one end, and the fixing of the male connection portion is also performed from the front side of the surface material. The structure that covers the fixture with the groove and the upper surface of the female connecting part side prevents the fixture from being exposed to the outside,
Further, by providing a sealing material at a position outside of the fixture, a joint structure of a panel having enhanced waterproofness, airtightness, corrosion resistance, fire resistance, and engagement force is provided.
