[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0022] like Figures 1 to 6 As shown, this application embodiment provides a corner panel component 1 for an exterior wall, including: a main body, a first connecting edge 11, and a second connecting edge 12. The first connecting edge 11 is disposed on one side edge of the main body, and a plurality of protruding ribs 111 are provided on the side of the first connecting edge 11 away from the main body. A groove 112 is provided on one side of the first connecting edge 11 along the thickness direction. The second connecting edge 12 is disposed on the other side edge of the main body, and a plurality of recesses 121 are provided on the second connecting edge 12. When two corner panel components 1 are spliced together, each protruding rib 111 on the first connecting edge 11 of one component is respectively embedded in each recess 121 on the second connecting edge 12 of the other component. A fastener a can pass through the groove 112 at one end and be connected to the structure of the building.
[0023] The corner plate component 1 of this application has protruding ribs 111 and grooves 121 on both sides, which facilitates the initial interlocking of adjacent corner plates. Then, the corner plate component 1 can be fixed by fasteners a passing through the grooves 112, thus realizing a tight vertical connection between two adjacent corner plate components 1.
[0024] The factory building is quite large in length and width. Furthermore, the corner panel construction takes place after the adjacent exterior wall panels 2 on both sides of the corner have been completed. The installation process of the corner panel component 1 should be as simple as possible without affecting the protection of the already installed exterior wall panels 2 on both sides. At the same time, the area occupied by the gaps at the corner panel component is relatively large compared to other wall panels. Therefore, during the detailed construction process, factors such as the sealing, waterproofing, and aesthetics of the exterior wall should also be considered.
[0025] In the vertical direction, adjacent corner plate components 1 are joined by a seam structure formed by the protruding ribs 111 and the grooves 121. After the structure is self-connected, external supporting components are needed for secondary connection and fixation. For example, two horizontally parallel self-tapping screws are used to connect to the building structure, such as the vertical purlin 8 at the butt joint, through the grooves 112 of the first joint edge 11 for secondary fixation, so as to achieve a tight vertical connection between the two adjacent corner plate components and to connect the corner plate components to the external wall joists. The protruding ribs 111 of one of the two adjacent corner plate components 1 are inserted into the grooves 121 of the other to form a unique seam structure, which is roughly sawtooth spliced and forms a tortuous gap, preventing rainwater from flowing into the wall along the edge of the external wall and enhancing the sealing and waterproofing effect.
[0026] In some possible implementation schemes, combined Figure 1 and Figure 2 As shown, two protruding ribs 111 are provided on the thickness end face of the first connecting edge 11 facing away from the main body. The protruding ribs 111 are spaced apart sequentially along the thickness direction of the main body. Two recessed grooves 121 are provided on the thickness end face of the second connecting edge 12 facing away from the main body. The two recessed grooves 121 are spaced apart sequentially along the thickness direction of the main body. When the two corner plate components 1 are spliced together, the two protruding ribs 111 on the first connecting edge 11 of one component are respectively embedded into the two recessed grooves 121 on the second connecting edge 12 of the other component. The multiple protruding ribs 111 of one of the two adjacent corner plate components 1 are inserted into the multiple recessed grooves 121 of the other component, forming a unique interlocking structure, roughly a sawtooth splice, creating a tortuous gap. This prevents rainwater from flowing into the wall along the outer wall edge, enhancing the sealing and waterproofing effect.
[0027] In some possible implementations, a stepped groove 113 is provided on one side of the first connecting edge 11 along the thickness direction, and an extension piece 122 is provided on one side of the second connecting edge 12 along the thickness direction. The groove 112 is provided on the stepped groove 113. When the two corner plate components 1 are spliced together, the extension piece 122 on the second connecting edge 12 of one is embedded in the stepped groove 113 on the first connecting edge 11 of the other. The extension piece 122 is provided with a clearance opening corresponding to the groove 112. The extension piece 122 has the function of covering the splicing position, thereby achieving an aesthetic effect.
[0028] This application also provides a corner plate installation structure for an exterior wall, including: multiple corner plate components 1 and fasteners a. Each corner plate component 1 is arranged sequentially along the height direction of the building. Two adjacent corner plate components 1 are spliced together by a first connecting edge 11 and a second connecting edge 12. One end of the fastener a passes through the first connecting edge 11 and is connected to the building body. The other end of the fastener a is confined within the groove 112 and does not protrude from the groove 112.
[0029] In some possible implementations, such as Figure 3 and Figure 4 As shown, for the connection structure between the horizontal corner plate component 1 and the exterior wall panel 2: the corner plate installation structure of the exterior wall may include a color steel plate strip 3, there is a gap between the corner plate component and the adjacent exterior wall panel 2, the color steel plate strip 3 is respectively attached to the corner plate component and the adjacent exterior wall panel 2, and covers the gap, and one end of the fastener a passes through the color steel plate and is connected to the structure of the building.
[0030] The vertical gaps connecting the corner panel component 1 and the exterior wall panel 2 are sewn together by the color steel plate strip 3, and the color steel plate strip 3 is fixed to the vertical purlin 8 of the butt joint with self-tapping screws.
[0031] In some possible implementations, such as Figure 4 As shown, the corner panel installation structure of the exterior wall includes butyl tape 4, which is pressed and positioned between the color steel plate strip 3 and the corner panel component or exterior wall panel 2. The butyl tape 4 seals the contact gap between the color steel plate strip 3 and the corner panel component 1 or between the color steel plate strip 3 and the exterior wall panel 2, preventing rainwater from flowing into the interior along the gaps in the wall panel.
[0032] In some possible implementation schemes, combined Figure 5 As shown, the corner plate installation structure of the exterior wall includes a starting bracket 5, which is installed on the building structure. The starting bracket 5 has an upper protrusion 51. When the corner plate component 1 is supported by the starting bracket 5, the upper protrusion 51 is embedded in the groove 121 on the second connecting edge 12 of the corner plate component 1.
[0033] In this embodiment, at the starting point of the exterior wall panel 2, a preliminary mechanical engagement is achieved using a starting bracket 5 that matches the contour of the groove 121 of the lowest corner panel. The starting bracket 5 serves to support the bottom corner panel component 1, and can be fixed to the building structure using fasteners a.
[0034] In some possible implementations, the starting bracket 5 includes a vertical bonding plate 52 and a horizontal support plate 53. The upper protrusion 51 is vertically connected to the horizontal support plate 53, and the vertical bonding plate 52 is connected to the horizontal support plate 53. The vertical bonding plate 52 has a through hole for a fastener a to pass through. The corner plate component 1 is supported on the horizontal support plate 53. The fastener a can pass through the through hole in the vertical bonding plate at one end and be connected to the building structure, such as to the horizontal purlin 9.
[0035] In some possible implementations, the corner panel installation structure of the exterior wall includes a color-coated steel sheet edge trim 6, which has a connecting plate 61, an inclined plate 62, and an edge plate segment 63. Fasteners a pass through the starting bracket 5 and the connecting plate 61 in sequence and are connected to the structure of the building. The upper edge of the inclined plate 62 is connected to the connecting plate 61. The inclined plate 62 extends out of the corner panel member 1 along the thickness direction of the corner panel member 1. The edge plate segment 63 is connected to the lower edge of the inclined plate 62.
[0036] The corner plate installation structure of the exterior wall also includes a galvanized sheet folding piece 7, which includes a vertical section 71 and a horizontal section 72. The vertical section 71 is located on the side of the connecting plate 61 away from the starting bracket 5. Fasteners a pass through the starting bracket 5, the connecting plate 61 and the vertical section 71 in sequence and are connected to the building structure. The horizontal section 72 is connected to the vertical section 71 on one side and extends to the edge of the building's sill wall on the other side. The horizontal section 72 is attached to the top end face of the building's sill wall.
[0037] This embodiment of the application utilizes two components—the color-coated steel edge trim 6 and the galvanized steel folding piece 7—to prevent damp ground moisture and collected rainwater from directly flowing back into the room. Simultaneously, the inclined plate 62 design of the color-coated steel edge trim 6 helps water collected on the exterior wall panel 2 drain along the inclined angle. The tight fit between the galvanized steel folding piece 7 and the ground sill also prevents damp ground moisture from seeping into the room. The shape design of the upper protrusion 51 of the starting support 5 matching the groove 112 of the lowest corner plate component 1, along with its own triangular shape, also enhances the stability of the support.
[0038] The preferred embodiments disclosed above are merely illustrative of this application. These preferred embodiments do not exhaustively describe all details, nor do they limit the application to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this application, thereby enabling those skilled in the art to better understand and utilize this application. This application is limited only by the claims and their full scope and equivalents.
