[0039] As Figures 1 - 8 shown, this embodiment provides a prefabricated wall panel, which includes a keel frame 1, an inner wall panel 2, an outer wall panel 3, and an edge-sealing wall panel 4. The inner wall panel 2 is arranged at one end of the keel frame 1 and is provided with a first connecting groove 21 extending in the first direction. The keel frame 1 abuts in the first connecting groove 21. The outer wall panel 3 is arranged at the other end of the keel frame 1 and is arranged parallel and facing each other with a certain interval from the inner wall panel 2. The outer wall panel 3 is provided with a second connecting groove 31 extending in the first direction. The keel frame 1 abuts in the second connecting groove 31. The edge-sealing wall panel 4 is arranged along the circumference of the keel frame 1 and is clamped and connected between the inner wall panel 2 and the outer wall panel 3.
[0040] In this embodiment, the prefabricated wall panel includes a keel frame 1, an inner wall panel 2, an outer wall panel 3, and an edge-sealing wall panel 4. These components can all be standardized produced in the factory, and only need to be assembled on site, thus shortening the construction period and improving the construction efficiency. The inner wall panel 2 is arranged at one end of the keel frame 1 and is provided with a first connecting groove 21 extending in the first direction. The keel frame 1 abuts in the first connecting groove 21. The outer wall panel 3 is arranged at the other end of the keel frame 1 and is arranged parallel and facing each other with a certain interval from the inner wall panel 2. The outer wall panel 3 is provided with a second connecting groove 31 extending in the first direction. The keel frame 1 abuts in the second connecting groove 31. The keel frame 1, as the core support structure of the prefabricated wall panel, by abutting in the first connecting groove 21 and the second connecting groove 31, not only facilitates the construction and installation of the operators, but also helps to ensure the stability of the keel frame 1. The edge-sealing wall panel 4 is arranged along the circumference of the keel frame 1 and is clamped and connected between the inner wall panel 2 and the outer wall panel 3, thereby further improving the connection strength of each component, making the overall structure of the prefabricated wall panel more stable and improving its load-bearing capacity. Through the above settings, the prefabricated wall panel of this embodiment can be easily assembled, improving the construction quality and efficiency.
[0041] It should be noted that the connections between the keel frame 1 and the inner wall panel 2, as well as between the keel frame 1 and the outer wall panel 3, can all be realized by screws or bolts, which not only improves the connection strength of each component, but also facilitates disassembly and assembly, improving the construction efficiency. Moreover, most of the disassembled parts can be reused, saving the construction cost.
[0042] Specifically, as Figures 1 - 3As shown, the keel frame 1 includes a plurality of vertical rods 11 and a plurality of horizontal rods 12. The plurality of vertical rods 11 are parallel to each other and arranged at intervals, and are abutted between the first connection groove 21 and the second connection groove 31, which can improve the stability of each component and prevent the vertical rods 11 from moving. The two ends of the horizontal rod 12 are respectively connected to two adjacent vertical rods 11. The plurality of horizontal rods 12 are parallel to each other and arranged at intervals between two adjacent vertical rods 11, thereby forming a stable grid structure, which can enhance the overall stiffness of the keel frame 1 and make the prefabricated wall panel more stable when bearing external forces such as wind pressure and earthquake. Among them, in this embodiment, the vertical rod 11 is made of I-shaped steel, and the horizontal rod 12 is made of square tube, so as to facilitate local material selection and improve the overall strength of the prefabricated wall panel. In other embodiments, the keel frame 1 can be made of materials such as steel, cold-formed thin-walled steel, aluminum profile, and steel bar truss, and the specific quantity is arranged according to calculation and structural requirements.
[0043] In this embodiment, as Figure 2 and Figure 3 shown, there are two vertical rods 11. The two vertical rods 11 are parallel to each other and arranged at intervals, and are abutted between the first connection groove 21 and the second connection groove 31, which can improve the stability of each component. The two ends of the horizontal rod 12 are respectively connected to the two vertical rods 11. The plurality of horizontal rods 12 are parallel to each other and arranged at intervals, which can enhance the overall stiffness of the keel frame 1. In other embodiments, the specific quantity of the vertical rods 11 can be adjusted according to the specific structure of the prefabricated wall panel, and no more limitations are imposed here.
[0044] More specifically, as Figure 2 and Figure 3 shown, there are a plurality of first connection grooves 21 and a plurality of second connection grooves 31. The plurality of first connection grooves 21 are arranged at intervals at one end of the inner page wall panel 2 facing the keel frame 1 and are arranged in one-to-one correspondence with the plurality of vertical rods 11, so that the end faces of the two ends of the vertical rod 11 are respectively abutted in the first connection groove 21 and the second connection groove 31 corresponding thereto. The plurality of second connection grooves 31 are arranged at intervals at one end of the outer page wall panel 3 facing the keel frame 1 and are arranged in one-to-one opposite directions with the plurality of first connection grooves 21. Construction workers can more easily ensure the accurate alignment and tight connection between the keel frame 1 and the inner page wall panel and the outer page wall panel 3, thereby improving the installation accuracy and overall effect. Not only that, through the above settings, double connections are formed between the inner page wall panel 2 and the outer page wall panel 3 and the keel frame 1, further enhancing the connection stability between the components and reducing deformation or loosening caused by external forces. Moreover, it can ensure that the vertical rods 11 of the keel frame 1 can evenly distribute the force to the inner page wall panel 2 and the outer page wall panel 3 when stressed, which helps to reduce the concentration of local stress and improve the bearing capacity and durability of the prefabricated wall panel.
[0045] More specifically, in this embodiment, there are two first connection grooves 21 and two second connection grooves 31. The two first connection grooves 21 are spaced apart at one end of the inner wall panel 2 facing the keel frame 1 and are arranged in one-to-one correspondence with the two vertical rods 11, so that the end faces of both ends of the vertical rod 11 are respectively abutted in the first connection groove 21 and the corresponding second connection groove 31. The two second connection grooves 31 are spaced apart at one end of the outer wall panel 3 facing the keel frame 1 and are arranged in one-to-one facing with the two first connection grooves 21. Construction workers can more easily ensure the accurate alignment and tight connection between the keel frame 1, the inner wall panel and the outer wall panel 3, thereby improving the installation accuracy and overall effect. In other embodiments, the specific number of the first connection grooves 21 and the second connection grooves 31 can be determined by calculation according to the specific structure of the prefabricated wall panel, and no excessive limitation is made here.
[0046] Specifically, as Figures 1 - 4 shown, an installation hole 22 is formed in the inner wall panel 2, and a first embedded part 13 is provided on the keel frame 1. The first embedded part 13 passes through the installation hole 22. The first embedded part 13 is used to connect the embedded part at the bottom of the structural beam to improve the strength and stability of the overall structure. In addition, through the cooperation of the first embedded part 13 and the installation hole 22, a more firm connection is formed between the inner wall panel 2 and the keel frame 1. Since the embedded part usually has high strength and rigidity, it can ensure that the connection between the wall panel and the keel frame 1 will not loosen or fall off due to external force. Among them, as Figure 3 shown, in this embodiment, the first embedded part 13 includes a column body and an end plate. One end of the column body is connected to the vertical rod 11 of the keel frame 1, and the other end is connected to the end plate, thereby increasing the connection area between the keel frame 1 and the inner wall panel 2 and improving the connection strength. In other embodiments, the first embedded part 13 can also adopt an anchor rod, that is, the specific structure of the first embedded part 13 is not limited, as long as the above functions can be realized.
[0047] More specifically, as Figure 3 and Figure 4 shown, there are multiple installation holes 22 and multiple first embedded parts 13. The multiple first embedded parts 13 are arranged at the four corners of the keel frame 1 and extend out from the multiple installation holes 22 one by one, ensuring that the force on the inner wall panel 2 can be evenly distributed to the keel frame 1, thereby reducing the concentration of local stress, improving the load-bearing capacity and durability of the overall structure, and also facilitating the construction workers to carry out the external hanging installation operation of the prefabricated wall panel.
[0048] Specifically, as Figures 1 - 6As shown in the figure, the edge-sealing wall panel 4 includes two transverse sealing plates 41 and two vertical sealing plates 42. The two transverse sealing plates 41 are parallel to each other and are arranged at both ends of the keel frame 1 at intervals along the first direction. The two vertical sealing plates 42 are parallel to each other and are arranged at both ends of the keel frame 1 at intervals along the second direction. The second direction is perpendicular to the first direction, thereby realizing the edge-sealing effect on the side of the prefabricated wall panel, preventing foreign matters such as sediment from entering it, and moreover, it is also convenient for the operators to assemble and construct, improving the construction efficiency and the connection strength and stability of the overall structure.
[0049] More specifically, as Figures 1 - 7 shown, the vertical sealing plate 42 is provided with a connecting recess 421, and the transverse sealing plate 41 is provided with a connecting convex portion 411 that cooperates with the connecting recess 421. By engaging the connecting convex portion 411 in the connecting recess 421, the vertical sealing plate 42 and the transverse sealing plate 41 can be connected to each other. Such a setting makes the connection between the vertical sealing plate 42 and the transverse sealing plate 41 tighter and more stable. Moreover, through the precise cooperation of the connecting convex portion 411 and the connecting recess 421, the relative movement between the transverse sealing plate 41 and the vertical sealing plate 42 can be effectively prevented, thereby improving the structural stability of the entire prefabricated wall panel.
[0050] Even more specifically, in this embodiment, in order to improve the connection strength between the connecting convex portion 411 and the connecting recess 421, bolts are passed through the connecting convex portion 411 and the connecting recess 421 along the second direction, thereby realizing the connection with the vertical sealing plate 42 from the side of the transverse sealing plate 41, avoiding interference with the installation and use of related embedded parts. In other embodiments, the connecting convex portion 411 and the connecting recess 421 can also be reinforced and connected through pins, that is, the specific connection method between the connecting convex portion 411 and the connecting recess 421 is not limited.
[0051] Specifically, as Figures 1 - 8 shown, both ends of the transverse sealing plate 41 are enlarged ends 412, and the enlarged ends 412 are clamped between the first connecting groove 21 and the second connecting groove 31, thereby increasing the contact area between the transverse sealing plate 41 and the first connecting groove 21 and the second connecting groove 31, and thus improving the connection stability.
[0052] More specifically, as Figures 1 - 8 shown, the vertical sealing plate 42 includes a left sealing plate 422 and a right sealing plate 423. One end of the left sealing plate 422 is clamped to the keel frame 1, and the other end abuts between the groove walls of the first connecting groove 21 and the second connecting groove 31. One end of the right sealing plate 423 is clamped between the groove walls of the first connecting groove 21 and the second connecting groove 31, and the other end extends to the outside.
[0053] Specifically, as Figure 1 and Figure 2As shown, a second embedded part is provided on the end face of the inner wall panel 2, and holes are provided on the second embedded part to facilitate the installation operation of hanging or embedding the prefabricated wall panel by the operators. Among them, the second embedded part can be made of an L-shaped plate or a U-shaped plate, and the specific structure of the second embedded part is not limited herein.
[0054] More specifically, in this embodiment, there are a total of four second embedded parts. Two of the second embedded parts are respectively arranged at intervals on the upper end face of the inner wall panel 2, and the other two second embedded parts are arranged at intervals on the lower end face of the inner wall panel 2 to facilitate the operators to install the prefabricated wall panel according to the on-site operation conditions. In other embodiments, the specific quantity and installation position of the second embedded part can be adjusted according to the actual operation memory and are not limited too much herein.
[0055] Specifically, the inner wall panel 2, the outer wall panel 3, and the edge-sealing wall panel 4 can all be made of solid waste recycling materials with a fire protection grade of A such as foamed ceramics. The wall panel made of foamed ceramics not only has fire protection performance but also has excellent physical properties such as light weight, high strength, heat preservation and heat insulation, and good weather resistance. In addition, through the recycling of waste, the construction cost is saved.
[0056] More specifically, the interior of the prefabricated wall panel can be filled with other thermal insulation and fire protection materials such as glass wool, basalt mineral wool, and polyurethane, which is easy to meet the building energy conservation requirements in cold and severe cold regions.
[0057] As Figures 1 - 10 shown, this embodiment also provides a combined wall panel. The combined wall panel includes prefabricated wall panels. There are multiple prefabricated wall panels, and multiple prefabricated wall panels can be spliced pairwise in sequence. It is not only easy to meet the building requirements such as fire protection, energy conservation, and sound insulation, but also easy to meet the building structure requirements such as bearing capacity and durability. It is convenient for on-site assembly. Since the components used are small, a single person can complete the handling work. The installation is convenient, the construction difficulty is reduced, and the labor force is saved. In addition, most of the components after disassembly can be reused, shortening the construction period and saving costs.
[0058] As Figures 1 - 10 shown, for two adjacent prefabricated wall panels, a groove will be formed between the inner wall panel 2, the outer wall panel 3, and the left sealing plate 422, and the right sealing plate 423 extends out from between the inner wall panel 2 and the outer wall panel 3 and can be connected to the groove of the adjacent prefabricated wall panel, thereby realizing the stable connection of two adjacent prefabricated wall panels. In addition, the prefabricated wall panel is installed by adopting hanging or wire support, which is convenient for the operators to construct.
[0059] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
