Description

Technical Field

[0001] This application relates to the field of prefabricated buildings, and in particular to a prefabricated wall structure and its construction method. Background Technology

[0002] With the development of modern industrial technology, house construction can now be done in batches, much like machine production. Prefabricated house components are simply transported to the construction site and assembled. Prefabricated walls are a commonly used building material in prefabricated construction, and their use shortens the construction time for walls.

[0003] Utility model patent CN207672771U discloses a prefabricated wall panel, comprising several wall panels. A plug is fixedly mounted on one side of each wall panel, and a slot for inserting the plug is located on the side of another wall panel. A limiting mechanism for positioning the plug is provided in each wall panel. A receiving hole is located above and communicates with the slot in each wall panel. The limiting mechanism includes a sliding rod located in the receiving hole and vertically slidably connected to the wall panel. A limiting member is provided on the wall panel to prevent the sliding rod from moving downwards and to be detachable from the sliding rod. The plug has an insertion hole for inserting the sliding rod. When the sliding rod is inserted into the insertion hole, its upper end is located in the receiving hole. A grouting hole communicating with the slot is provided on the wall panel.

[0004] When several wall panels are fixed at their ends in sequence, rainwater from the outside impacts the joints between adjacent wall panels. Rainwater can easily seep into the wall panels through the joints, increasing the moisture content and making the wall plaster prone to collapse from the end face of the wall panels, thus reducing the safety of the wall panels. Summary of the Invention

[0005] To address the issue of rainwater easily seeping into adjacent wall panels through the joints, this application provides a prefabricated wall structure and its construction method.

[0006] Firstly, this application provides a prefabricated wall structure, which adopts the following technical solution:

[0007] A prefabricated wall structure includes multiple wall panels and multiple sealing plates. One end of each wall panel is connected to a fixing block, and the other end of each wall panel has a fixing groove for the fixing block to be embedded in. Both ends of each wall panel have sealing grooves for the ends of the sealing plates to be embedded in. Each sealing groove corresponds to a sealing plate. Multiple sealing rods are connected to the end face of each sealing plate. Multiple sealing holes are formed on the inner wall of each sealing groove. These sealing holes are used for embedding the sealing rods to form a fixation. When a fixing block is embedded in a fixing groove on an adjacent wall panel, the sealing grooves of two adjacent wall panels are connected. The two ends of each sealing plate are embedded in the sealing grooves of two adjacent wall panels, and the outer circumferential wall of the sealing plate abuts against the inner wall of the sealing groove to form a seal. Simultaneously, each sealing rod is embedded in a corresponding sealing hole, and the outer circumferential wall of the sealing rod abuts against the inner wall of the sealing hole to form a fixation.

[0008] By adopting the above technical solution, during the installation of prefabricated walls, multiple wall panels are placed sequentially. Fixing blocks on the wall panels are embedded into fixing grooves on adjacent wall panels, with the outer circumferential wall of the fixing block abutting against the inner circumferential wall of the fixing groove to form a fixation, thus achieving the installation of multiple wall panels. Simultaneously, the sealing grooves between adjacent wall panels correspond one-to-one and are connected. The sealing plate corresponds one-to-one with the sealing groove, with both ends of the sealing plate embedded into the sealing grooves on two adjacent wall panels. The sealing rod and sealing hole correspond one-to-one, with the outer circumferential wall of the sealing rod abutting against the inner circumferential wall of the sealing hole to form a fixation, thus fixing the sealing plate at the connection point of two adjacent wall panels. When rainwater impacts the end face of the sealing plate, rainwater is less likely to penetrate through the sealing plate into the connection point of the two wall panels, improving the anti-seepage function of the prefabricated wall. The moisture content of the wall panels is less likely to increase, and the wall cladding is less likely to collapse from the end face of the wall panels, thereby improving the safety of the wall panels in use.

[0009] Optionally, the sealing plate includes a waterproof layer and a water-absorbing and color-changing layer. The end face of the waterproof layer is fixed to the end face of the water-absorbing and color-changing layer. The sealing rod is located on the side of the water-absorbing and color-changing layer away from the waterproof layer. The outer circumferential wall of the water-absorbing and color-changing layer abuts against the inner wall of the sealing groove to form a seal, and the end face of the waterproof layer is flush with the end face of the wall panel.

[0010] By adopting the above technical solution, when the two ends of the sealing plate are embedded into the sealing grooves of two adjacent wall panels, the outer circumferential wall of the sealing rod abuts against the inner wall of the sealing hole to form a fixation, and the outer circumferential wall of the water-absorbing and color-changing layer abuts against the inner wall of the sealing groove to form a fixation. Furthermore, the end face of the waterproof layer is flush with the end face of the wall panel, making it difficult for rainwater to penetrate the waterproof layer into the water-absorbing and color-changing layer, thereby improving the sealing stability between the two adjacent wall panels. Simultaneously, when the pre-installed wiring conduit in the wall panel ages and breaks, water from the conduit seeps into the wall panel. The outer circumferential wall of the water-absorbing and color-changing layer abuts against the inner wall of the sealing groove to form a seal, increasing the humidity of the wall panel. The water-absorbing and color-changing layer absorbs the water in the wall panel and changes color, allowing the user to directly observe which wall panel has a damaged wiring conduit, thus alerting the user to repair the aged and damaged conduit and extending the service life of the wall panel.

[0011] Optionally, a cover plate is rotatably connected to the wall panel, and a clamping groove is provided on the end face of the waterproof layer away from the water-absorbing and color-changing layer for the end of the cover plate to be inserted. The end of the cover plate rotates toward the direction of the waterproof layer and is inserted into the clamping groove. The end of the cover plate abuts against the inner wall of the clamping groove to form a fixed position, and the end face of the cover plate is flush with the end face of the water-absorbing and color-changing layer.

[0012] By adopting the above technical solution, when the sealing plate is embedded in the sealing groove to form a fixed position, the end of the cover plate rotates towards the direction of the waterproof layer and is embedded in the abutting groove. The end of the cover plate abuts against the inner wall of the abutting groove to form a fixed position, which further improves the connection stability of the sealing plate on the wall panel. At the same time, the end face of the cover plate is flush with the end face of the wall panel, thereby ensuring the flatness of the end face of the wall panel.

[0013] Optionally, a reinforcing assembly is connected to the wall panel. A reinforcing cavity is formed in the inner wall of the fixing groove, and the reinforcing cavity communicates with the sealing groove. The reinforcing assembly includes a reinforcing rod and a reinforcing elastic element. The reinforcing rod is slidably connected to the inner wall of the reinforcing cavity. One end of the reinforcing rod faces the sealing groove, and the other end faces the fixing groove. A reinforcing groove is formed on the end face of the fixing block for the end of the reinforcing rod to be embedded. One end of the reinforcing elastic element in the elastic direction is connected to the inner wall of the reinforcing cavity, and the other end of the reinforcing elastic element in the elastic direction is connected to the end face of the reinforcing rod. The reinforcing elastic element has the elasticity to drive the reinforcing rod to slide towards the sealing groove, and the end of the reinforcing rod tends to protrude from the inner wall of the sealing groove. When the sealing plate is embedded in the sealing groove, the end face of the sealing plate abuts against the end face of the reinforcing rod and drives the reinforcing rod to slide towards the fixing groove. The end of the reinforcing rod is embedded in the reinforcing groove, and the outer wall of the reinforcing rod abuts against the inner wall of the reinforcing groove to form a fixation.

[0014] By adopting the above technical solution, when the fixing block is embedded in the fixing groove, the outer circumferential wall of the fixing block abuts against the inner wall of the fixing groove to form a fixation, thereby fixing the adjacent wall panels. At the same time, the sealing grooves of the two adjacent wall panels correspond one-to-one and are connected. The two ends of the sealing plate are embedded one-to-one into the sealing grooves of the two adjacent wall panels. The end face of the sealing plate abuts against the end face of the reinforcing rod and drives the reinforcing rod to slide towards the fixing block. The end of the reinforcing rod is embedded in the reinforcing groove, and the outer circumferential wall of the reinforcing rod abuts against the inner wall of the reinforcing groove to form a fixation, thereby increasing the clamping force between the two adjacent wall panels and making it less likely for the adjacent wall panels to separate, thus improving the connection stability between the adjacent wall panels.

[0015] Optionally, the reinforcing assembly further includes a reinforcing rack and a reinforcing gear. The reinforcing rack is slidably connected to the inner wall of the reinforcing cavity. The sliding direction of the reinforcing rack and the sliding direction of the reinforcing rod are perpendicular to each other. The end of the reinforcing rack protrudes from the inner wall of the fixing groove. The reinforcing gear is rotatably connected to the inner wall of the reinforcing cavity. The reinforcing rack meshes with the reinforcing gear. The outer wall of the reinforcing rod has a toothed groove that meshes with the reinforcing gear. When the fixing block is embedded in the fixing groove, the fixing block abuts against the end face of the reinforcing rack and drives the reinforcing rack to slide towards the reinforcing cavity. The reinforcing gear rotates and guides the end of the reinforcing rod to be embedded in the reinforcing groove.

[0016] By adopting the above technical solution, when multiple wall panels are installed, the fixing blocks correspond one-to-one with the fixing grooves. The fixing blocks are embedded in the fixing grooves, and the outer circumferential wall of the fixing blocks abuts against the inner wall of the fixing grooves to form a fixation, thereby realizing the assembly of multiple wall panels. At the same time, the end face of the fixing block abuts against the end face of the reinforcing rack, driving the reinforcing rack to slide towards the reinforcing cavity. The reinforcing gear rotates and guides the end of the reinforcing rod to be embedded in the reinforcing groove, so that the sealing plate stably drives the end of the reinforcing rod to be embedded in the reinforcing groove, thereby further facilitating the installation of the wall panels by the workers.

[0017] Optionally, the reinforcing rod includes an elastic part and a driving part, the ends of the elastic part and the driving part are connected, the reinforcing elastic element is located on the driving part, the tooth groove is located on the driving part, the end of the driving part away from the elastic part faces the sealing groove, and the end of the elastic part away from the driving part faces the fixing groove.

[0018] By adopting the above technical solution, when the fixed block abuts against the end face of the reinforcing rack and drives the reinforcing rack to slide towards the reinforcing cavity, the end face of the elastic part abuts against the end face of the fixed block and undergoes a certain deformation. When the reinforcing cavity is connected to the reinforcing groove, the end face of the elastic part is guided to embed into the reinforcing groove, thereby achieving the initial positioning of the reinforcing rod on the inner wall of the reinforcing groove.

[0019] Optionally, a prompting strip is connected to the outer wall of the drive unit. When the elastic part is guided and embedded in the reinforcing groove, the end face of the prompting strip is flush with the inner wall of the sealing groove.

[0020] By adopting the above technical solution, when the reinforcing gear rotates and the end of the guide elastic part is embedded in the reinforcing groove, the end face of the indicator strip is flush with the inner wall of the sealing groove. The staff can directly observe whether the elastic part is embedded in the reinforcing groove, without the need for the staff to repeatedly adjust the position between the wall panels, thereby further facilitating the installation of the wall panels.

[0021] Optionally, the reinforcing component further includes a transmission gear, which is coaxially connected to the rotating shaft of the cover plate. The outer wall of the reinforcing rod has a toothed groove that meshes with the transmission gear. When the reinforcing rod slides toward the direction of the fixed groove, the transmission gear rotates, causing the end of the cover plate to rotate toward the direction of the waterproof layer and embed into the clamping groove.

[0022] By adopting the above technical solution, when the sealing plate is embedded in the sealing groove, the end face of the sealing plate abuts against the end of the reinforcing rod and drives the reinforcing rod to slide towards the direction of the fixing groove. The gear meshes with the toothed drive gear, which drives the end of the cover plate to rotate towards the direction of the waterproof layer and embed into the abutting groove. The end of the cover plate abuts against the inner wall of the abutting groove to form a fixed position. There is no need for the staff to drive the cover plate to rotate, realizing the automatic rotation of the cover plate and further improving the ease of installation of the prefabricated wall.

[0023] Optionally, the cover plate includes a rotating part and a spring-loaded part, the end of the rotating part is connected to the end of the spring-loaded part, the end of the rotating part away from the spring-loaded part is rotatably connected to the wall plate, the transmission gear is located on the rotating part, and the end of the spring-loaded part away from the rotating part is used to be embedded in the clamping groove to form a fixation.

[0024] By adopting the above technical solution, when the cover plate rotates towards the waterproof layer, the rebound part undergoes a certain deformation and is embedded in the clamping groove. The outer circumferential wall of the rebound part presses against the inner wall of the clamping groove to form a fixation, thereby improving the connection stability of the sealing plate on the wall panel.

[0025] Secondly, this application provides a prefabricated wall construction method, which adopts the following technical solution:

[0026] A prefabricated wall construction method includes the following steps:

[0027] Positioning groove excavation: In accordance with installation design requirements, positioning grooves are excavated in the ground for the bottom of the wall panel to be embedded.

[0028] The wall panel splicing involves sequentially embedding the ends of multiple wall panels into positioning grooves, embedding fixing blocks into fixing grooves, and pressing the outer circumferential wall of the fixing blocks against the inner wall of the fixing grooves to form a fixation, thereby achieving the splicing of each wall panel.

[0029] The sealing plate is fixed, with each sealing plate corresponding to a sealing groove. Both ends of the sealing plate are embedded into the sealing groove between adjacent wall panels. The outer circumferential wall of the sealing plate is pressed against the inner wall of the sealing groove to achieve fixation. Cement is poured at the connection between the sealing plate and the inner wall of the sealing groove to fix the sealing plate to the inner wall of the sealing groove.

[0030] By adopting the above technical solution, the positioning groove facilitates the splicing of multiple wall panels. The outer wall of the fixing block abuts against the inner wall of the fixing groove to form a fixation, realizing the splicing of each wall panel into a whole. The sealing plate is embedded into the sealing groove of the two adjacent wall panels one by one, realizing the fixation of the sealing plate on the wall panel. This makes it difficult for rainwater to penetrate into the wall panel when it impacts the sealing plate, the humidity of the wall panel is not easily aggravated, and the wall cladding is not easy to collapse from the end face of the wall panel, thereby improving the safety of the wall panel.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The installation of sealing plates and sealing rods prevents rainwater from easily penetrating into the joint between the two wall panels, thus improving the anti-seepage function of the prefabricated wall. It also prevents the moisture in the wall panels from aggravating the problem and makes the wall plaster less likely to collapse from the end face of the wall panels, thereby improving the safety of the wall panels.

[0033] 2. The installation of waterproof and water-absorbing color-changing layers serves as a reminder to users to repair aging and damaged cable pipes inside the wall panels, thereby extending the service life of the wall panels;

[0034] 3. The cover plate is designed to be fixed by pressing the end of the cover plate against the inner wall of the sealing groove, thereby improving the connection stability of the sealing plate on the wall panel. Attached Figure Description

[0039] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0040] This application discloses a prefabricated wall structure. (Refer to...) Figure 1 and Figure 2A prefabricated wall structure includes multiple wall panels 1 and multiple sealing plates 2. The wall panels 1 are square panels. Multiple fixing blocks 3 are uniformly cast and fixed at one end along the length of the wall panel 1. The arrangement direction of the fixing blocks 3 is parallel to the height direction of the wall panel 1. Multiple fixing grooves 11 are uniformly spaced at the other end along the length of the wall panel 1 for the fixing blocks 3 to be embedded in. The arrangement direction of the fixing grooves 11 is parallel to the height direction of the wall panel 1. Sealing grooves 12 are formed at the four corners of the wall panel 1 for the ends of the sealing plates 2 to be embedded in. The sealing grooves 12 penetrate the outer wall of the wall panel 1 along its height direction.

[0041] Reference Figure 1 and Figure 2 When the fixing block 3 is embedded in the fixing groove 11, the outer wall of the fixing block 3 presses against the inner wall of the fixing groove 11 to form a fixation, thereby achieving splicing and fixing of multiple wall panels 1. The sealing grooves 12 between two adjacent wall panels 1 are interconnected. The two ends of the sealing plate 2 are embedded into the sealing grooves 12 on the two adjacent wall panels 1 respectively. The outer wall of the sealing plate 2 presses against the inner wall of the sealing groove 12 to achieve fixation. The sealing plate 2 covers the connection between adjacent wall panels 1, making it difficult for rainwater to enter the wall panel 1 through the sealing plate 2, so that the moisture of the wall panel 1 is not easily aggravated, and the wall cladding is not easily collapsed from the end face of the wall panel 1, thereby improving the safety of the wall panel 1.

[0042] Reference Figure 1 and Figure 3 The sealing plate 2 is a square plate, comprising a waterproof layer 21 and a water-absorbing and color-changing layer 22. In this embodiment, the waterproof layer 21 is made of polyurethane waterproof coating, which has good anti-seepage function. The water-absorbing and color-changing layer 22 is made of anhydrous copper sulfate. The waterproof layer 21 is coated on the end face of the water-absorbing and color-changing layer 22 to form a fixed structure. Multiple sealing rods 4 are uniformly cast and fixed on the end face of the water-absorbing and color-changing layer 22 away from the waterproof layer 21. The multiple sealing rods 4 are divided into two groups, located on both sides of the width direction of the sealing plate 2. The arrangement direction of the sealing rods 4 in the same group is parallel to the length direction of the sealing plate 2. Multiple sealing holes 13 are uniformly opened on the inner wall of the sealing groove 12. The arrangement direction of the sealing holes 13 is parallel to the height direction of the wall panel 1. The sealing holes 13 are used for the end of the sealing rods 4 to be embedded and fixed, increasing the clamping force between the sealing plate 2 and the wall panel 1, making it less likely for the sealing plate 2 to detach from the wall panel 1, thereby improving the connection stability of the sealing plate 2 on the wall panel 1.

[0043] Reference Figure 1 and Figure 2Two cover plates 5 are rotatably connected to the top of the wall panel 1. The rotation axis of the cover plates 5 is parallel to the length direction of the wall panel 1. The cover plates 5 are located on the side of the wall panel 1 closest to the fixing groove 11, and the two cover plates 5 are located on both sides of the width direction of the wall panel 1. The cover plates 5 include a rotating part 51 and a spring-loaded part 52. In this embodiment, the rotating part 51 is made of stainless steel and has a certain structural strength. In this embodiment, the spring-loaded part 52 is made of rubber and has a certain deformation capability. The ends of the rotating part 51 and the spring-loaded part 52 are fixed and form an "L" shape, with the end of the spring-loaded part 52 away from the rotating part 51 facing the sealing groove 12.

[0044] Reference Figure 1 The end face of the waterproof layer 21 away from the water-absorbing and color-changing layer 22 is provided with a clamping groove 211 for the end of the rebound part 52 to be inserted. When the rotating part 51 rotates toward the direction of the sealing groove 12, it drives the rebound part 52 to rotate toward the direction of the waterproof layer 21. The rebound part 52 is squeezed by the waterproof layer 21 and undergoes a certain deformation and is inserted into the clamping groove 211. The outer wall of the rebound part 52 is pressed against the inner wall of the clamping groove 211 to form a fixed shape, and the end face of the rebound part 52 is flush with the end face of the waterproof layer 21, which further improves the connection stability of the sealing plate 2 on the wall panel 1.

[0045] Reference Figure 2 and Figure 3 Two reinforcing components 6 are connected to the wall panel 1, and each reinforcing component 6 corresponds to a cover plate 5. A reinforcing cavity 14 is formed on the inner wall of the fixing groove 11 near the cover plate 5 to accommodate the reinforcing component 6. The reinforcing cavity 14 penetrates the outer wall of the wall panel 1 and connects to the sealing groove 12 in the direction near the sealing groove 12. Furthermore, the reinforcing cavity 14 penetrates the outer wall of the wall panel 1 in the direction near the cover plate 5 and faces the rotation shaft of the rotating part 51.

[0046] Reference Figure 2 and Figure 3 The reinforcing component 6 includes a reinforcing rod 61, a reinforcing elastic element 62, a reinforcing rack 63, a reinforcing gear 64, and a transmission gear 65. The reinforcing rod 61 includes an elastic portion 611 and a driving portion 612, both of which are strip-shaped rods. The end of the elastic portion 611 is coaxially fixed to the end of the driving portion 612. In this embodiment, the driving portion 612 is made of stainless steel, providing a certain structural strength, while the elastic portion 611 is made of rubber, providing a certain deformation capability. The reinforcing rod 61 is slidably connected to the inner wall of the reinforcing cavity 14. The sliding direction of the reinforcing rod 61 is parallel to the width direction of the wall panel 1. The end of the elastic portion 611 away from the driving portion 612 faces the fixing groove 11, and the end of the driving portion 612 away from the elastic portion 611 faces the sealing groove 12.

[0047] Reference Figure 2 and Figure 3The reinforcing elastic element 62 can be a compression spring or a tension spring. In this embodiment, the reinforcing elastic element 62 is a compression spring, which has a certain deformation capability. One end of the reinforcing elastic element 62 in the direction of elastic force is fixed to the inner wall of the reinforcing cavity 14, and the other end of the reinforcing elastic element 62 in the direction of elastic force is fixed to the outer wall of the driving part 612. The direction of elastic force of the reinforcing elastic element 62 is parallel to the width direction of the wall panel 1. The reinforcing elastic element 62 has the elastic force to drive the reinforcing rod 61 to slide towards the sealing groove 12, and the end of the reinforcing rod 61 tends to protrude from the inner wall of the sealing groove 12.

[0048] Reference Figure 2 and Figure 3 A reminder strip 7 is fixed to the inner wall of the drive unit 612 near the sealing groove 12. The reinforcing elastic member 62 drives the reinforcing rod 61 to slide towards the sealing groove 12, and the reminder strip 7 is located inside the sealing groove 12. A reinforcing groove 31 is provided on the end face of the fixing block 3 for the reinforcing rod 61 to be inserted. The reinforcing groove 31 extends through the end face of the fixing block 3 along the width direction of the wall panel 1.

[0049] Reference Figure 2 and Figure 3 A reinforcing rack 63 is slidably connected to the inner wall of the reinforcing cavity 14. The sliding direction of the reinforcing rack 63 is parallel to the length direction of the wall plate 1. The end of the reinforcing rack 63 protruding from the inner wall of the fixing groove 11 is used to abut against the end face of the fixing block 3. A reinforcing gear 64 is rotatably connected to the inner wall of the reinforcing cavity 14. The rotation axis of the reinforcing gear 64 is parallel to the height direction of the wall plate 1. The reinforcing rack 63 meshes with the reinforcing gear 64. The end face of the reinforcing rod 61 facing the reinforcing gear 64 has a toothed groove 613, and the inner wall of the toothed groove 613 meshes with the reinforcing gear 64. A transmission gear 65 is coaxially fixed on the rotation shaft of the rotating part 51.

The end face of the reinforcing rod 61 has a toothed groove 614, and the inner wall of the toothed groove 614 meshes with the transmission gear 65.

[0050] Reference Figure 2 and Figure 3When adjacent wall panels 1 are spliced, the fixing block 3 is embedded in the fixing groove 11, the end face of the fixing block 3 abuts against the end face of the reinforcing rack 63, and drives the reinforcing rack 63 to slide towards the reinforcing cavity 14. The end face of the reinforcing rack 63 is flush with the inner wall of the fixing groove 11. At the same time, the reinforcing gear 64 rotates, and the guide elastic part 611 is embedded in the reinforcing groove 31, realizing the splicing and fixing of adjacent wall panels 1. The sealing grooves 12 on the two adjacent wall panels 1 correspond one-to-one and are connected. The two ends of the sealing plate 2 in the width direction are embedded one-to-one in the sealing grooves 12 on the two adjacent wall panels 1. The sealing rod 4 corresponds one-to-one with the sealing hole 13 and is embedded. The outer wall of the sealing rod 4 abuts against the inner wall of the sealing hole 13 to form a fixation, and the water absorption changes The end face of the color layer 22 abuts against the end face of the drive part 612, and drives the drive part 612 to slide towards the fixing groove 11. The reinforcing rod 61 is embedded in the reinforcing groove 31, and the outer wall of the reinforcing rod 61 abuts against the inner wall of the reinforcing groove 31. At the same time, it drives the transmission gear 65 to rotate, and drives the spring part 52 to rotate towards the pressing groove 211 and embed into the pressing groove 211. The outer wall of the spring part 52 abuts against the inner wall of the pressing groove 211 to form a fixation, thereby achieving the sealing of the connection between the sealing plate 2 and the adjacent wall panel 1. This makes it difficult for rainwater to penetrate into the inner wall of the wall panel 1, the humidity of the wall panel 1 is not easy to rise, and the wall cladding is not easy to collapse from the end face of the wall panel 1, thereby improving the safety of the wall panel 1.

[0051] The implementation principle of a prefabricated wall structure in this application embodiment is as follows: When adjacent wall panels 1 are spliced, the fixing block 3 is embedded in the fixing groove 11, the end face of the fixing block 3 abuts against the end face of the reinforcing rack 63, and drives the reinforcing rack 63 to slide towards the reinforcing cavity 14. The end face of the reinforcing rack 63 is flush with the inner wall of the fixing groove 11. At the same time, the reinforcing gear 64 rotates, and the guide elastic part 611 is embedded in the reinforcing groove 31, thereby realizing the splicing and fixing of adjacent wall panels 1. The sealing grooves 12 on the two adjacent wall panels 1 correspond one-to-one and are connected. The two ends of the sealing plate 2 in the width direction are embedded one-to-one in the sealing grooves 12 on the two adjacent wall panels 1. The sealing rod 4 corresponds one-to-one with the sealing hole 13 and is embedded. The outer wall of the sealing rod 4 abuts against the sealing hole 13. The inner wall is fixed, the end face of the water-absorbing and color-changing layer 22 is pressed against the end face of the driving part 612, and the driving part 612 is driven to slide towards the fixed groove 11. The reinforcing rod 61 is embedded in the reinforcing groove 31, and the reinforcing rod 61 is pressed against the inner wall of the reinforcing groove 31 from the outer wall. At the same time, it drives the transmission gear 65 to rotate, and drives the rebound part 52 to rotate towards the pressing groove 211 and be embedded in the pressing groove 211. The rebound part 52 is pressed against the inner wall of the pressing groove 211 from the outer wall to form a fixed position, thereby achieving the sealing of the connection between the sealing plate 2 and the adjacent wall panel 1. This makes it difficult for rainwater to penetrate into the inner wall of the wall panel 1 from the end face of the sealing plate 2, and the humidity of the wall panel 1 is not easy to rise. The wall cladding is not easy to collapse from the end face of the wall panel 1, thereby improving the safety of the wall panel 1.

[0052] This application also discloses a method for constructing prefabricated walls, including the following steps:

[0053] Positioning groove excavation: In accordance with the installation design requirements, a positioning groove is excavated in the ground for the bottom of wall panel 1 to be embedded.

[0054] The wall panels 1 are spliced ​​by sequentially embedding the ends of multiple wall panels 1 into the positioning grooves, and the fixing blocks 3 are embedded into the fixing grooves 11. The fixing blocks 3 are pressed against the inner wall of the fixing grooves 11 from the outer wall to form a fixation, thereby realizing the splicing of each wall panel 1.

[0055] The sealing plate 2 is fixed, and the sealing plate 2 corresponds one-to-one with the sealing groove 12. The two ends of the sealing plate 2 are embedded one-to-one into the sealing groove 12 between adjacent wall panels 1. The outer wall of the sealing plate 2 is pressed against the inner wall of the sealing groove 12 to achieve fixation. Cement is poured at the connection between the sealing plate 2 and the inner wall of the sealing groove 12 to achieve fixation of the sealing plate 2 on the inner wall of the sealing groove 12.

[0056] The implementation principle of the prefabricated wall construction method in this application embodiment is as follows: the positioning groove is set to facilitate the splicing of multiple wall panels 1. The outer wall of the fixing block 3 is pressed against the inner wall of the fixing groove 11 to form a fixation, so that each wall panel 1 can be spliced ​​to form a whole. The sealing plate 2 is embedded in the sealing groove 12 on the adjacent two wall panels 1 to fix the sealing plate 2 on the wall panel 1. This makes it difficult for rainwater to penetrate into the wall panel 1 when it impacts the sealing plate 2, the humidity of the wall panel 1 is not easily aggravated, and the wall surface is not easy to collapse from the end face of the wall panel 1, thereby improving the safety of the wall panel 1.
