Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0019] Embodiment 1: As Figures 1 - 3 shown, the present utility model provides a vertical internal corner node structure for a hidden-nail installed exterior wall metal enclosure panel, including: a keel 4, an internal corner decorative plate 1 is fixedly arranged on one side of the keel 4, a self-tapping screw 5 is inserted through the interior of the internal corner decorative plate 1, the self-tapping screw 5 is inserted into the interior of the keel 4, the self-tapping screw 5 is threadedly connected to the internal corner decorative plate 1 and the keel 4, a fixing member 2 is arranged on one side of the internal corner decorative plate 1, a self-tapping screw 5 is also inserted through the interior of the fixing member 2, the self-tapping screw 5 inside the fixing member 2 is inserted into the interior of the keel 4, the self-tapping screw 5 is threadedly connected to the fixing member 2 and the keel 4, and a metal enclosure panel body 3 is hung on one side of the fixing member 2.

[0020] The effect achieved by the entire Embodiment 1 is that the keel 4 is first connected to the fixing member 2 fixed on the wall surface for fixing and supporting the metal enclosure panel body 3 and the internal corner decorative plate 1. The internal corner decorative plate 1 is fixed to the keel 4 by the self-tapping screw 5, and the metal enclosure panel body 3 is fixed to the keel 4 by the fixing member 2 using the self-tapping screw 5, completing the installation of the internal corner node structure for the hidden-nail installation of the metal enclosure panel body 3.

[0021] Embodiment 2: As Figures 1 - 3 shown, the shape of the internal corner decorative plate 1 is an inverted double L shape, the outer shape of the upper folded edge of the metal enclosure panel body 3 is a flat male buckle; the lower folded edge of the metal enclosure panel body 3 is provided with a groove female buckle, and the groove female buckle on the lower folded edge of the metal enclosure panel body 3 fits with the upper male buckle; the width of the internal corner decorative plate 1 is 100mm 50mm + 50mm, the thickness of the internal corner decorative plate 1 is 0.6mm, and the length of the internal corner decorative plate 1 is 3000 - 5000mm; the external dimensions of the fixing member 2 are 50mm × 80mm × 1.5mm, and the self-tapping screw 5 is M5.5*32mm in diameter.

[0022] The effect achieved by the entire Embodiment 2 is that the vertical internal corner node structure of the exterior wall metal enclosure panel body 3 is applicable to the above-mentioned model specifications of profiled steel sheets. If there are situations such as constructing other exterior wall metal enclosure panel bodies 3 with different model specifications and vertical internal corner decorative plates, etc., the corresponding dimensions such as the length, height, and thickness of the internal corner decorative plate parts are adjusted, but the form of the vertical internal corner node structure of the exterior wall metal enclosure panel body 3 remains unchanged.

[0023] Working principle: The first step is to install the keel 4. Lay out the lines on the wall according to the positions of the keel 4 for the external wall enclosing metal plates as shown in the design drawings. Install the keel 4 according to the position lines. The keel 4 can be fixed using post-embedded chemical rivets or embedded parts. Adjust the position of the keel 4 so that its flatness, position and other indicators meet the design requirements. The second step is to install the internal corner trim plate 1. Lay out the position lines on the keel 4 according to the position of the internal corner trim plate 1. Place the internal corner trim plate 1 on the position lines of the keel 4 and adjust its position, then fix it with self-tapping screws 5. The third step is to install the fixing part 2. Mark the position ink lines of the fixing part 2 on the keel 4. Then place the processed fixing part 2 on the keel 4, align it with the marked ink lines, and fix it with self-tapping screws 5 (rivets). The fourth step is to install the main body 3 of the external wall profiled metal enclosing plate. According to the layout drawing of the installation position of the main body 3 of the external wall profiled metal enclosing plate, lay out the position lines of the main body 3 of the metal enclosing plate on the keel 4. Install the main body 3 of the first-layer metal enclosing plate from bottom to top according to the position lines. First, insert the male buckle fold on the upper side of the main body 3 of the metal enclosing plate into the groove of the fixing part 2, and then use self-tapping screws 5 to firmly fix the fixing part 2 and the main body 3 of the metal enclosing plate on the keel 4. Finally, hang the female buckle on the lower side of the upper main body 3 of the metal enclosing plate into the groove of the fixing part 2, and insert the male buckle on the upper side of the main body 3 of the metal enclosing plate into the groove of the upper fixing part 2. Fix the upper main body 3 of the metal enclosing plate and the upper fixing part 2 on the keel 4 with self-tapping screws 5 in the same way as the previous step to complete the installation of the upper main body 3 of the metal enclosing plate. Repeat this installation method until the installation of the main body 3 of the metal enclosing plate for the entire wall is completed. The upper and lower sides of the main body 3 of the metal enclosing plate at the topmost and lowermost layers are both wrapped with special edging parts.
