Therefore, they should not be construed as limitations on this utility model.

[0028] Please see Figure 1-4 A type of cement foam board for installation at exterior wall corners without cutting, and its connectors, comprising a foam board body 1 and a connector 2. The connector 2 is used to connect two foam board bodies 1 to form a structural unit suitable for exterior wall corners, effectively solving the problems of cutting and splicing in traditional installation, and improving construction efficiency and installation accuracy.

[0029] The connector 2 comprises two mutually perpendicular outer side plates 201, which form the external frame of the corner, providing basic support and positioning for the entire structure, ensuring overall flatness and verticality, and improving the neatness and aesthetics of the building's appearance. A connecting plate 203 is provided between the two outer side plates 201, and the connecting plate 203 is positioned along the mirror plane between the two outer side plates 201. This structural design allows the connecting plate 203 to evenly distribute the pressure from the foam board bodies 1 on both sides, enhancing the overall mechanical performance and stability of the connector 2. Multiple locking blocks 204 are evenly distributed on both sides of the connecting plate 203, connecting to the foam board body 1. The locking blocks 204 cooperate with the slots 3 provided on the foam board body 1, forming a quick, simple, and stable connection method. When the locking blocks 204 are inserted into the slots 3, they effectively restrict the displacement of the foam board body 1 in the horizontal and vertical directions, preventing loosening or misalignment during use, and ensuring the reliability and durability of the connection. The connector 2 also includes two inner side plates 202, and a connecting plate 203 is disposed between the inner side plates 202 and the outer side plates 201. The inner side plates 202 further enhance the structural strength of the connector 2, and when connected to the foam board body 1, they can work together with the outer side plates 201 to clamp and fix the foam board body 1 from both inside and outside, so that the foam board body 1 fits more tightly to the connector 2, thereby improving the overall integrity and stability of the entire structure.

[0030] One end of the foam board body 1 is flat, and the other end is beveled. This design allows the beveled surfaces of the two foam board bodies 1 to smoothly align with the locking blocks 204 of the connector 2 during corner installation, eliminating the need for on-site cutting. This greatly simplifies the construction process, improves efficiency, and reduces material waste and quality issues caused by cutting. Furthermore, the beveled end of the foam board body 1 has multiple slots 3 that match the locking blocks 204, and these slots are evenly distributed. The uniform distribution of the slots 3 ensures that the locking blocks 204 are subjected to uniform force during insertion, avoiding localized stress concentration and thus improving the stability and reliability of the connection. In addition, the depth and width of the slots 3 precisely match the dimensions of the locking blocks 204, effectively preventing them from coming loose during use and further enhancing the strength of the connection.

[0031] A recessed surface 4 is provided on one side of the foam board body 1. When the foam board body 1 is connected to the connector 2, the outer side of the recessed surface 4 abuts against the inner side of the outer panel 201. This abutting connection increases the contact area between the foam board body 1 and the connector 2, making the connection between the two tighter and more stable. At the same time, the outer end face of the outer panel 201 is set at the same level as the outer side of the foam board body 1, ensuring a flat and aesthetically pleasing overall appearance after installation. A second recessed surface 5 is also provided on the foam board body 1. When the foam board body 1 is connected to the connector 2, the outer side of the second recessed surface 5 abuts against the inner side of the inner panel 202. Similar to the function of the first recessed surface 4, the second recessed surface 5 further enhances the connection stability between the foam board body 1 and the connector 2, supporting and fixing the foam board body 1 from the inside, preventing deformation or displacement under stress. Furthermore, the outer side of the inner side panel 202 is set on the same horizontal plane as the other outer side of the foam board body 1, which also ensures the flatness and aesthetics of the overall structure.

[0032] Furthermore, the connector 2 is also provided with a locking hole 205 for easy locking connection with the foam board body 1, and the foam board body 1 is provided with a through hole 6 for easy connection with the connector 2. When the connector 2 is connected to the foam board body 1, the connection is made by locking with screws and nuts through the locking hole 205 and the through hole 6. This locking method provides additional reinforcement to the connection between the connector 2 and the foam board body 1, further enhancing the stability and reliability of the entire structure. The tightening force of the screws and nuts can effectively resist the action of external forces, preventing the foam board body 1 and the connector 2 from loosening or separating during long-term use, ensuring the safety and durability of the external wall insulation and decoration system.

[0033] Furthermore, multiple locking holes 205 and through holes 6 are provided, and the number of both is equal, evenly distributed at corresponding positions on the connector 2 and the foam board body 1. The even distribution of multiple locking holes 205 and through holes 6 ensures that the connection force is evenly distributed across the entire contact surface of the connector 2 and the foam board body 1, avoiding excessive or insufficient localized stress, thereby improving the uniformity and stability of the connection. This evenly stressed connection method can better cope with various external forces, effectively protecting the integrity and stability of the exterior wall structure.

[0034] Furthermore, the foam board body 1 is also provided with waist-shaped slots 7 for easy connection with pre-embedded anchors on the wall. The design of the waist-shaped slots 7 has multiple advantages. On the one hand, it facilitates the connection operation between the foam board body 1 and the pre-embedded anchors on the wall during installation. Construction workers can adjust the position of the foam board body 1 within the range of the waist-shaped slots 7 to achieve precise positioning of the foam board body 1, making it fit better against the wall and ensuring the accuracy and tightness of the installation. On the other hand, the waist-shaped slots 7 can, to a certain extent, accommodate the slight displacement of the wall caused by factors such as temperature changes and settlement, avoiding damage to the foam board body 1 or connection failure due to wall deformation, thus improving the adaptability and reliability of the entire external wall insulation and decoration system.

[0035] Furthermore, the foamed board body 1 comprises a cement foam layer 101, a sound-absorbing board layer 102, and a finishing layer 103. The cement foam layer 101 and the sound-absorbing board layer 102 are fixedly connected. The finishing layer 103 is a sprayed layer, applied to the sound-absorbing board layer 102 by spraying. The cement foam layer 101, as the main insulation layer, has excellent thermal insulation performance, effectively preventing heat transfer within the wall, reducing building energy consumption, and achieving energy conservation and emission reduction goals. The sound-absorbing board layer 102 is made of polyurethane foam, which has excellent sound absorption performance, absorbing and reducing noise transmission inside and outside the building, providing a quiet and comfortable indoor environment, and improving the building's acoustic performance. The finishing layer 103 is made of fluorocarbon exterior wall coating and is sprayed onto the sound-absorbing panel layer 102 through a spraying process. Fluorocarbon exterior wall coating not only has a good decorative effect and can provide a wide variety of color choices for buildings to meet the needs of different architectural styles, but also has excellent weather resistance, corrosion resistance and stain resistance, which can maintain the beauty and cleanliness of the exterior wall for a long time and reduce the cost and frequency of exterior wall maintenance.
