Description

TECHNICAL FIELD

[0001] The application relates to the technical field of prefabricated interior partition wall plates, in particular to a fabricated ALC strip plate interior wall structure and a construction process thereof. BACKGROUND

[0002] The ALC strip plate interior wall is a multi-porous concrete formed plate mainly made of fly ash (or silica sand), cement, lime and the like, and is internally reinforced with treated steel bars, and has good sound insulation effect. Due to the characteristics of solid plate, water and electricity need to be slotted, light weight, easy installation and the like, the ALC strip plate interior wall has the properties of fireproof, moisture-proof, environmental protection, heat preservation, high strength, flame retardant and good sound insulation effect, and has become the preferred material for indoor partition in modern buildings. At present, the ALC strip plate interior wall is increasingly widely used in the field of construction, but its installation mode still has certain limitations, especially the installation efficiency and stability under the condition of limited space need to be improved.

[0003] The existing ALC plate usually adopts a concave-convex groove (mortise and tenon joint) plug-in connection mode, specifically, the ALC plate is provided with male and female mortise and tenon joints (convex and concave grooves) on both sides, when installing the ALC wall plate, the wall plate needs to be lifted and aligned with the upper and lower baselines, and then a crowbar or the like is used to move the ALC wall plate, so that two adjacent ALC wall plates are plugged together, and special polymer bonding mortar (sometimes mixed with anti-cracking fibers) is fully applied at the plate joint (especially the vertical joint) to tightly bond the adjacent strip plates together, so that the connection of the wall plate can be realized.

[0004] However, a large installation space is required in actual operation, and the assembly process is complex, especially the finishing assembly of the last wall plate is difficult, and a sufficient side plug-in space is required during installation, while the indoor installation space is usually limited, resulting in complex assembly operation and low efficiency. In addition, the stability of the splicing connection is insufficient, the lateral bearing capacity of the partition wall formed is weak, and the risk of tilting is easy to occur, so further improvement is required. SUMMARY

[0005] Compared with the prior art, the present application mainly solves the problems of large plug-in space required during installation of the ALC strip plate interior wall, complex assembly operation, insufficient splicing stability and weak lateral bearing capacity, and provides a fabricated ALC strip plate interior wall structure and a construction process thereof.

[0006] The fabricated ALC strip plate interior wall structure and the construction process thereof provided by the present application adopt the following technical scheme: An assembled ALC batten inner wall structure and a construction process thereof, comprising an ALC plate body, a reserved splicing part and a locking assembly, the reserved splicing part is arranged on the side edge of the ALC plate body and is used to realize the buckling connection with the reserved splicing part of the adjacent ALC plate body through the relative movement in the thickness direction, the reserved splicing part comprises a protruding part and a groove part, the shapes of the protruding part and the groove part are arranged in cooperation with each other, the protruding parts of the adjacent two ALC plate bodies are engaged and abutted with each other, and the locking assembly is used to fix the adjacent two reserved splicing parts.

[0007] By adopting the above technical scheme, the reserved splicing part is arranged on the side edge of the ALC plate body, and the reserved splicing part comprises the protruding part and the groove part which are arranged in cooperation with each other, after one ALC plate body is installed at the corresponding position, the next ALC plate body is moved along the thickness direction, so that the reserved splicing parts of the adjacent ALC plate bodies can realize the buckling connection through the relative movement in the thickness direction, and the buckling connection does not need additional insertion space, thereby reducing the problem that a large side insertion space is needed in the traditional installation mode, being suitable for the installation scene with limited space, greatly simplifying the splicing operation and improving the installation efficiency.

[0008] Meanwhile, the protruding parts of the adjacent two ALC plate bodies are engaged and abutted with each other, and the locking assembly is used to fix the adjacent two reserved splicing parts, thereby enhancing the stability of the splicing connection, improving the lateral bearing capacity of the formed partition wall, reducing the risk of collapse, improving the stress performance and leveling effect of the splicing joint, reducing the cracking problem, and coating the special polymer bonding mortar at the plate joint to enhance the sealing performance and stability and prolong the service life.

[0009] Preferably, the two side surfaces of the single ALC plate body are respectively provided with the protruding parts, and the two protruding parts are respectively arranged flush with the opposite two side surfaces of the ALC plate body, so that the cross section of the ALC plate body presents a continuous Z-shaped structure.

[0010] By adopting the above technical scheme, the protruding parts arranged on the two side surfaces of the single ALC plate body are arranged flush with the opposite two side surfaces, so that the cross section of the ALC plate body presents a continuous Z-shaped structure, the structure design can make the reserved splicing parts of the adjacent ALC plate bodies not need additional side insertion space when buckling, effectively reducing the space required for installation and being suitable for the installation scene with limited space; since the buckling mode is simple and direct, it is not necessary to use a crowbar or other tools to perform a complex moving operation as in the traditional mode, thereby greatly simplifying the splicing operation and improving the installation efficiency; and the continuous Z-shaped structure makes the protruding parts of the adjacent two ALC plate bodies engage and abut with each other more tightly, thereby enhancing the stability of the splicing connection, improving the lateral bearing capacity of the formed partition wall and reducing the risk of collapse; meanwhile, the tight engagement and abutment can also improve the stress performance and sealing effect of the splicing joint, reduce the cracking problem and prolong the service life of the structure.

[0011] Preferably, the two sides of a single ALC board body are respectively provided with the protrusions, and the two protrusions are respectively flush with the same side of the ALC board body, so that the cross-section of the ALC board body has a convex shape.

[0012] By adopting the above technical solution, based on the ALC board body and the reserved splicing part, the protrusions on both sides of a single ALC board body are flush with the same side to form a convex structure. Combined with the snap-fit ​​of the reserved splicing part, the insertion space required for installation is reduced, which is suitable for installation scenarios with limited space, simplifies the assembly operation, improves the installation efficiency, enhances the stability and lateral bearing capacity of the splicing connection, reduces the risk of tipping, improves the stress performance and sealing effect of the splice, and extends the service life.

[0013] Preferably, the locking assembly further includes a positioning element disposed between two adjacent protrusions.

[0014] By adopting the above technical solution, positioning installation can be performed by setting a positioning component between two adjacent positioning components, thereby improving positioning stability and installation convenience.

[0015] Preferably, the positioning element is a positioning protrusion disposed on one of the protrusions, and the other protrusion has a groove for the positioning protrusion to be engaged.

[0016] Preferably, the positioning protrusions are arranged at intervals along the height direction of the protrusion.

[0017] By adopting the above technical solution, several positioning protrusions are provided, which can increase the contact area and friction between the protrusions and the grooves when adjacent ALC panels are snapped together, making the snapping tighter and more stable. This further enhances the stability and firmness of the ALC panel splicing, reduces the possibility of loosening or cracking at the joints, and also improves the lateral bearing capacity of the entire prefabricated ALC panel interior wall structure, reducing the risk of tipping over.

[0018] Preferably, the locking assembly includes a tie rod and two nuts respectively threaded to both ends of the tie rod, and the protrusion is pre-drilled with a first through hole for the tie rod to pass through.

[0019] By adopting the above technical solution, after the reserved splicing parts of the ALC board body are interlocked, the tie rods can be passed through the first through hole of the protrusion and tightened with nuts at both ends, which further enhances the stability and lateral bearing capacity of the splicing connection, reduces the risk of tipping over, and improves the stress performance of the splice.

[0020] Preferably, the locking assembly further includes a fixing plate disposed between two adjacent protrusions, the fixing plate having a second through hole for the pull rod to pass through, and the fixing plate being fixed to the building roof or floor.

[0021] By adopting the above technical solution, a fixing plate is installed between two adjacent protrusions, and a second through hole is made on the fixing plate for the tie rod to pass through. The fixing plate is then fixed to the building's roof or floor, further enhancing the stability of the splicing between adjacent ALC panels. The fixing plate tightly connects two adjacent protrusions, making the entire ALC panel interior wall structure a more stable whole, reducing loosening or deformation at the splice points caused by external forces. Furthermore, the fixing of the fixing plate to the building's roof or floor effectively improves the connection strength between the ALC panel interior wall structure and the building structure, enhancing the overall integrity and reliability of the structure, further increasing the lateral bearing capacity of the ALC panel interior wall structure, reducing the risk of collapse, and ensuring the safety and stability of the ALC panel interior wall during use.

[0022] Preferably, it also includes a limiting component for improving lateral bearing capacity. The limiting component includes two first limiting plates respectively attached to both sides of the assembled ALC wall panel. The first limiting plates are fixed between the building roof slab and floor by a horizontal plate and bolts.

[0023] By adopting the above technical solution, the limiting component includes two first limiting plates respectively attached to both sides of the assembled ALC wall panel. The first limiting plates are fixed between the building's top slab and floor by a horizontal plate and bolts, which can effectively restrain the lateral displacement of the ALC wall panel, greatly enhance the lateral stability of the prefabricated ALC panel interior wall structure, significantly reduce the risk of the wall tilting or deforming due to lateral forces, and enable the wall to maintain good structural integrity and safety in complex use environments, further improving the reliability and durability of the entire building structure.

[0024] S1: Measure and lay out the lines, and mark the wall panel installation positioning control lines on the ground, ceiling and surrounding walls and columns; S2: Starting from one end of the wall, lift the first ALC board to the installation position, adjust its verticality and flatness, and then temporarily fix it with wooden wedges to align with the upper and lower baselines; S3: Align the groove of the second ALC board with the protrusion of the first board and push it towards the first ALC board to make them initially interlock. S4: Secure adjacent pre-reserved splice sections using the locking assembly; S5: Repeat steps S3 and S4 to install the subsequent wall panels in sequence; S6: Use a special polymer bonding mortar to fill the board joints to enhance sealing and stability; S7: Check the flatness and stress of the joints to ensure a secure installation.

[0025] By adopting the above technical solution, step S1 involves measuring and laying out the wall panel installation positioning control lines, providing an accurate positional reference for subsequent wall panel installation and making the installation more precise. Step S2 involves lifting the first ALC panel to the installation position, adjusting its verticality and flatness, temporarily fixing it with wooden wedges, and aligning it with the upper and lower baselines, ensuring the accuracy and stability of the first panel installation and laying a good foundation for subsequent splicing. Step S3 involves pushing the second ALC panel with its groove aligned with the protrusion of the first panel to achieve initial fastening. This fastening method, which uses relative movement in the thickness direction, eliminates the need for additional side insertion space, greatly reducing the space required for installation and making it suitable for installation scenarios with limited space. Step S4 involves using a pry bar to fine-tune the panel seams and checking whether the protrusions are engaged in the second groove, ensuring uniform panel seams and the reliability of the initial connection of the locking components, improving the stress performance and leveling effect of the splice. Step S5 involves fixing the adjacent reserved splice parts with the locking components, further enhancing the stability and lateral bearing capacity of the splice connection and reducing the risk of tipping over. Step S6 involves repeating the process to install subsequent wall panels sequentially, simplifying the assembly process and improving overall installation efficiency. Step S7 uses a special polymer bonding mortar to fill the panel joints, enhancing the sealing and stability between wall panels and extending their service life. Step S8 checks the flatness and stress distribution of the joints to ensure the entire prefabricated ALC panel interior wall structure is securely installed.

[0026] In summary, this application has the following beneficial effects: 1. The interlocking is achieved by reserving relative movement in the thickness direction of the splicing part, which reduces the insertion space required for installation and is suitable for installation scenarios with limited space; 2. The assembly process has been simplified, improving the installation efficiency of ALC panel interior walls; 3. The locking components enhance the stability and lateral load-bearing capacity of the splicing connection, reducing the risk of tipping over. Attached Figure Description

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 16 This application will be described in further detail below.

[0030] This application discloses a prefabricated ALC panel interior wall structure and its construction process.

[0031] Example 1: A prefabricated ALC panel interior wall structure, referring to Figure 1 The system includes an ALC panel body 1, a pre-installed splicing portion 2, and a locking assembly 3. In this embodiment, the ALC panel body 1 is installed on a building wall 4 with an installation space 41 for demonstration purposes. The pre-installed splicing portion 2 is located on the side of the ALC panel body 1 and is used to interlock with the pre-installed splicing portions 2 of adjacent ALC panel bodies 1 through relative movement in the thickness direction. The locking assembly 3 is used to fix two adjacent pre-installed splicing portions 2. This structural design reduces the insertion space required for installation and improves the stability and lateral load-bearing capacity of the splicing, because the interlocking method of the pre-installed splicing portions 2 does not require a large side insertion space, and the locking assembly 3 can further strengthen the connection.

[0032] Specifically, the pre-reserved splicing portion 2 includes a protrusion 21 and a groove 22. The protrusion 21 is characterized by its shape matching that of the groove 22, such as trapezoidal or rectangular shapes, to adapt to different installation requirements. In this embodiment, a rectangle is specifically shown so that adjacent protrusions 21 can interlock, and the protrusions 21 of adjacent ALC panel bodies 1 can abut against each other. The material of the protrusion 21 is the same as that of the ALC panel body 1, which is integrally formed from fly ash (or silica sand), cement, lime, and other raw materials through high-pressure steam curing. The groove 22 is a structure set on the side of the ALC panel body 1 to perfectly fit the protrusion 21. Its shape is determined according to the protrusion 21, and it is also integrally formed from the same material as the ALC panel body 1. When the protrusion 21 and the groove 22 are interlocked, they fit tightly together to form a stable connection structure.

[0033] Each ALC board body 1 has protrusions 21 on both sides, with two possible configurations. One configuration is that the two protrusions 21 are flush with the opposite sides of the ALC board body 1, such as... Figure 2 As shown, the cross-section of the ALC panel body 1 has a continuous Z-shaped structure. This structure makes the adjacent ALC panel bodies 1 more tightly connected when fastened, increases the stress area at the splicing point, and further improves the stability of the splicing. It should be noted that during use, only one side of the ALC panel body 1 needs to be pushed to speed up the installation process.

[0034] Another situation is as follows Figure 3 As shown, the two protrusions 21 are respectively flush with the same side of the ALC board body 1, so that the cross-section of the ALC board body 1 has a convex shape. This structure can better adapt to the spatial layout and improve the installation flexibility in certain installation scenarios. When in use, it is necessary to push the two sides separately for installation.

[0035] It should be noted that the ALC board main body 1 located on both sides of the installation space 41 can be as follows: Figure 2As shown, only one protrusion 21 is provided, specifically located at the end away from the installation space 41, or as shown in the image. Figure 4 The installation is shown with two protrusions 21. However, the building wall 4 is located on both sides of the installation space 41. One side needs to be pre-set with a protrusion 21 for the protrusion 21 to abut against in order to perform the fitting operation. The specific setting depends on the requirements.

[0036] Reference Figure 2 , Figure 5 The locking assembly 3 specifically includes a tie rod 31 and two nuts 32 threaded to both ends of the tie rod 31. In this embodiment, the tie rods 31 are spaced apart along the height direction of the ALC plate, depending on the requirements. The protrusion 21 is pre-drilled with a first through hole 211 for the tie rod 31 to pass through. A sleeve can be pre-embedded in the protrusion 21 to form the first through hole 211 for the tie rod 31 to pass through. Both ends of the first through hole 211 are set with countersunk grooves. The tie rod 31 is usually made of high-strength metal. The nuts 32 are adapted to the tie rod 31. By rotating the nuts 32, the tie rods 31 can be tightened, thereby tightly fixing the two adjacent protrusions 21 together and enhancing the stability of the splicing.

[0037] It should be noted that, in another embodiment, the tie rod 31 may be an eccentric adjusting screw, which can be adjusted in a certain displacement to improve the installation accuracy.

[0038] Reference Figure 6 Furthermore, the locking assembly 3 also includes a positioning element 33 disposed between two adjacent protrusions 21. The positioning element 33 is a positioning protrusion disposed on one of the protrusions 21. Correspondingly, the other protrusion 21 has a groove 212 for the positioning protrusion to be engaged. The positioning protrusion is generally columnar, and its cross-section can be trapezoidal, rectangular, or other shapes. In this embodiment, it is specifically shown as a trapezoid. Its material is similar to that of the ALC board body 1, and it has a certain strength and toughness. The groove 212 is a slot pre-cut in the protrusion 21 that matches the shape of the positioning protrusion. When adjacent ALC board bodies 1 are fastened together, the positioning protrusion will be engaged in the groove 212, further fixing the adjacent reserved splicing parts 2 and preventing relative displacement. This increases the friction and interlocking force when the protrusion 21 and the groove 22 are fastened together, making the fastening more secure and further improving the stability of the splicing.

[0039] The implementation principle of the prefabricated ALC panel interior wall structure in this embodiment is as follows: The prefabricated ALC panel interior wall structure in this embodiment directly connects the pre-reserved splicing part 2 through the protrusion 21 and groove 22, reducing the insertion space required for installation and simplifying the assembly operation. At the same time, the positioning protrusion and groove 212 in the locking assembly 3, as well as the fastening of the tie rod 31 and nut 32, greatly improve the stability of the splicing and the lateral bearing capacity, reducing the risk of tipping over. Compared with the prior art, this represents a significant improvement and enhancement.

[0040] This application also discloses a construction process, including the following steps: S1: Measurement and layout. Mark the wall panel installation positioning control lines on the ground, top and surrounding wall columns of building wall 4. Operators need to use measuring tools, such as laser level and tape measure, to ensure the accuracy of the positioning control lines and provide a precise benchmark for subsequent wall panel installation.

[0041] S2: Starting from one end of the wall, lift the first ALC panel body 1 to the installation position, adjust its verticality and flatness, and then temporarily fix it with wooden wedges 42. Figure 7 As shown, align the upper and lower baselines; when lifting the ALC panel body 1, hoisting equipment such as a crane can be used to ensure safety and efficiency. When adjusting the verticality and flatness, use tools such as a level for measurement and adjustment. The wooden wedges 42 are used to temporarily fix the ALC panel body 1 during installation to facilitate subsequent operations.

[0042] S3: After filling the inner wall of the protrusion 21 of the first ALC board body 1 with special polymer adhesive mortar, align the groove 22 of the reserved splicing part 2 of the second ALC board body 1 with the protrusion 21 of the first ALC board body 1, and push it towards the first ALC board body 1. That is, through relative movement in the thickness direction, the two are initially interlocked. During the pushing process, it should be done slowly and steadily to ensure that the protrusion 21 and the groove 22 can be accurately interlocked. After the adhesive mortar solidifies, it forms the first mortar layer 11, such as... Figure 2 , Figure 5 As shown. It should be noted that a pry bar is needed to fine-tune the panel gaps to ensure they are uniform. A pry bar is a common construction tool; by prying the ALC panel body 1, the width of the panel gaps can be fine-tuned to make them uniform. At the same time, carefully check the engagement of the first protrusion and the groove 212 to ensure the stability of the connection.

[0043] It is important to note that after installing one ALC panel body 1, the verticality and flatness must be measured by pressing a straightedge against the wall panel. If it meets the requirements, the installation of the next ALC panel body 1 can proceed. If an uneven area is found on the wall panel, one person needs to hold a straightedge while another person holds a wooden block against the wall panel. The wooden block is then gently tapped with a hammer to correct the unevenness. The verticality and flatness are then measured again by pressing a straightedge until the requirements are met.

[0044] S4: The adjacent pre-reserved splicing parts 2 are fixed by the locking assembly 3; specifically, the tie rod 31 is passed through the first through hole 211 of the protrusion 21, and then the nuts 32 are tightened at both ends to make the two adjacent protrusions 21 tightly fixed together. After the second ALC board body 1 and the first ALC board body 1 are installed, support templates can be set on both sides for support to reduce the possibility of tipping over.

[0045] S5: Repeat steps S3 and S4 to install the subsequent wall panels in sequence. Using the same method, install the subsequent ALC panel body 1 one by one until the installation of the entire interior wall structure is completed.

[0046] S6: After all the ALC panel bodies 1 located in one place are installed, use special polymer bonding mortar to fill the space between the ALC panel bodies 1 and the floor to perform underfilling. Before filling, it is necessary to clean up debris and wet the area. During filling, the panel body needs to be supported. After the filling mortar has solidified for a period of time, such as 48 hours, remove the wooden wedges 42 and backfill the area where the wooden wedges 42 were removed with mortar. Then, finish the entire base of the wall panel to form the second mortar layer 12. Figure 1 As shown.

[0047] Then, a special polymer bonding mortar is used to fill the gaps between the boards. After solidification, a third mortar layer is formed. After filling the board gaps, it needs to be smoothed to enhance sealing and stability. When filling the board gaps, it is important to ensure that the mortar is filled evenly to avoid gaps and improve the sealing and stability of the interior wall structure. During the process of filling the board gaps, self-adhesive fiberglass mesh can also be laid, and then another layer of mortar can be applied to ensure that there are no uneven surfaces or cracks at the board gaps.

[0048] S7: Check the flatness and stress of the joints to ensure a firm installation; use tools such as a level to check the flatness of the joints, and check the stress through observation and testing to ensure that the entire interior wall structure is firmly installed and meets the usage requirements.

[0049] This construction process achieves efficient and stable installation of prefabricated ALC panel interior wall structures through a series of orderly steps. From measurement and layout to final inspection, each step is closely coordinated to ensure the accuracy and quality of installation. Compared with existing technologies, this process reduces the interlocking space required for installation, simplifies assembly operations, and improves the stability and lateral load-bearing capacity of the joints, offering significant advantages.

[0050] Example 2: Reference Figure 8 The difference from Embodiment 1 is that in this embodiment, the surface of the protrusion 21 away from the ALC plate body 1 is provided with a first inclined surface 213, and correspondingly, the inner wall of the groove 22 is provided with a second inclined surface 221 that abuts against the first inclined surface 213. With the provision of the first inclined surface 213 and the second inclined surface 221, after the second inclined surface 221 abuts against the first inclined surface 213, a certain pressure can be applied to the protrusion 21 in the horizontal direction, thereby increasing the connection strength of the two protrusions 21 in the horizontal direction.

[0051] Example 3: Reference Figure 9 The difference from Embodiment 1 is that in this embodiment, the locking assembly 3 further includes a fixing plate 34 disposed between two adjacent protrusions 21. The fixing plate 34 has a second through hole for the pull screw 31 to pass through. The fixing plate 34 is fixed to the building roof or floor. Specifically, the top or bottom of the fixing plate 34 is fixedly connected to a horizontally extending transverse plate 5, which is arranged in an L-shape or T-shape, depending on the requirements. The transverse plate 5 is provided with mounting holes, and the entire structure is fixed to the building roof or floor by passing bolts 6 through the mounting holes.

[0052] When using this fixing plate 34 on an ALC panel body 1 with a continuous Z-shaped structure, after installing one ALC panel body 1, the horizontal plate 5 of the fixing plate 34 is inserted into the gap between the ALC panel body 1 and the building roof / floor. The mounting holes are fixed to the building roof / floor by bolts 6. During installation, the second through hole on the fixing plate 34 needs to be aligned with the first through hole 211, and then the special polymer bonding mortar is filled in before the next ALC panel body 1 is installed.

[0053] When applied to an ALC panel body 1 with a convex-shaped structure, the fixing plate 34 can be installed as described above. However, since the ALC panel body 1 needs to be pushed from both sides sequentially for installation, and the installation position of each ALC panel body 1 is determined by marking lines at the beginning, the fixing plate 34 can be installed to the building roof / floor using bolts 6 before installing the ALC panel body 1. The specific installation method can be selected according to the requirements.

[0054] Example 4: Reference Figure 10 The difference from Embodiment 1 is that it also includes a limiting member 7 for improving lateral bearing capacity. The limiting member 7 includes a first limiting plate 71, at least one of which is provided for attaching to the side wall of the assembled ALC wall panel and fitting against the protrusion 21. The first limiting plate 71 is fixed to the building roof / floor by a horizontal plate 5 and bolts 6. Specifically, the horizontal plate 5 is fixedly connected to the first limiting plate 71 in an L-shaped arrangement. When there are two first limiting plates 71, they are fixedly connected to the building roof and floor respectively, which provides better support for the ALC panel body 1 compared to a single first limiting plate 71. In this embodiment, the first limiting plate 71 is usually made of metal or high-strength plastic, and its function is to limit the lateral displacement of the ALC wall panel, improve the lateral bearing capacity of the entire interior wall structure, and ensure its safe use.

[0055] Regarding the fixing of the first limiting plate 71, when applied to the ALC panel body 1 with a continuous Z-shaped structure, the length directions of the two first limiting plates 71 are parallel to the length direction of the installation space 41. They can be set along the entire length of the installation space 41. Before installing the ALC panel body 1, the two first limiting plates 71 are first installed on the building roof and floor respectively using bolts 6, both on the same side. It should be noted that a third through hole can be opened in the first limiting plate 71, corresponding to the first through hole 211, for the tie rod 31 to pass through. It should be noted that the length of the first limiting plate 71 can be reduced to reduce the cost of the corresponding first limiting plate 71, depending on the specific requirements.

[0056] Regarding the fixing of the first limiting plate 71, when applied to the ALC plate body 1 with a continuous convex structure, since the ALC plate body 1 is pushed from both sides during installation, the length of the first limiting plate 71 is reduced. The first limiting plate 71 is installed after one ALC plate body 1 is installed, and after installation, both ends of the first limiting plate 71 cannot extend beyond the groove 22 at the far end of the ALC plate body 1. Furthermore, during installation, several first limiting plates 71 are staggered and distributed on both sides of the ALC plate body 1.

[0057] It should be noted that when this embodiment is combined with Embodiment 3, the fixing plate 34 and the first limiting plate 71 can be fixed to both sides of a horizontal plate 5, i.e., as shown in the figure. Figure 11 As shown, the first limiting plate 71 can also be fixed to one side of the horizontal plate 5, while the fixing plate 34 can be fixed to the lower surface of the horizontal plate 5. The horizontal plate 5 has a notch, such as... Figure 12 As shown, or Figure 13As shown, the horizontal plate 5 is a rectangular plate, which can increase the number of bolts 6 to improve the connection strength between the limiting member 7 and the building top / bottom plate, depending on the specific requirements.

[0058] Example 5: Reference Figure 14 The difference from Embodiment 1 is that in this embodiment, the limiting member 7 includes a second limiting plate 72, which is installed on the other side of the ALC panel body 1 and is disposed opposite to the first limiting plate 71. In this embodiment, the length of the second limiting plate 72 is relatively short, and it needs to be installed on the building roof and floor before the installation of the next ALC panel body 1. In order to reduce the impact on the installation of the next ALC panel body 1, it is necessary to avoid the protrusion 21 on the next ALC panel body 1. For this purpose, the second limiting plate 72 has an avoidance groove 711 for the next protrusion 21 to move in the thickness direction.

[0059] Furthermore, referring to Figure 15 To improve installation strength, the first limiting plate 71 and the second limiting plate 72 can be fixed to a horizontal plate 5, the cross-section of which is U-shaped. It should be noted that when this embodiment is combined with embodiment 3, such as... Figure 16 As shown, the fixing plate 34 is positioned between the first limiting plate 71 and the second limiting plate 72, and is fixed to the lower surface of the horizontal plate 5.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
