Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a joiner device for joining building exterior wall materials.

(Prior Art) As a joiner device for joining building exterior wall materials, for example, one described in Japanese Utility Model Application Publication No. 128842/1983 is known.

This conventional device has a vertical cross section that includes a horizontal surface portion of the elongated body, a rising portion protruding along the longitudinal direction at the center of the short surface of the horizontal surface portion, and a fitting portion provided at the tip of the rising portion. A locking body formed in a UT shape, a panel whose plate thickness at least at the end that will serve as a joint is equal to or less than the dimension of the rising part, and a long body with a gutter-like longitudinal section and has elasticity. , and a cover having a fitting claw protruding from the center of the short back surface along the longitudinal direction, the back surface of the horizontal surface portion of the locking body is fixed on a frame, and the panel is arranged on the frame. At the same time, the ends of the panels to be connected to each other cover the horizontal surface part of the locking body, and the edges of the panels are sandwiched between the ends of the panels, and the ends of the panels that become the joints are connected to the frame. a head of the fixing tool, which is fixed to the panel via a fixing tool, and the fitting claw of the cover is fitted into the fitting part of the locking body through elastic deformation, so that the head part of the fixing tool is exposed at the end of the panel; And the joint part was covered with a cover.

(Problems to be Solved by the Invention) In the conventional joiner device, since the insertion portion protrudes from the panel surface, the cover protrudes significantly from the panel surface, which is not desirable in terms of appearance. In order to solve this problem, the ends of the panel had to be made lower than the other side and the cover had to be recessed, which was expensive in terms of cost.

Furthermore, in the conventional method, the panels are assembled using the rising part of the locking body as a guide, so the gap between the panels on both sides of the joint is small, making it easy for rainwater to enter due to capillary action, and improving breathability. There was a problem that the durability of the exterior wall materials and the building frame decreased.

Furthermore, since the panels on both sides are close to each other, if there is a difference in the thickness of both panels, this step will become sharp, resulting in a large slope of the cover, creating a gap between the cover and the panel, which prevents rainwater. There was a problem that it was easy to infiltrate.

Therefore, an object of the present invention is to provide a joiner device for joining building exterior wall materials that solves the above-mentioned problems.
