[0008] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0009] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0010] like Figures 1-20As shown, the prefabricated lightweight wall panel of this utility model includes a wall panel body 1 assembled together, an anti-expansion component, and a finishing layer 3. The wall panel body 1 has a cavity and several inlets 2 communicating with the cavity for injecting grout. The anti-expansion component is located inside and / or outside the wall panel body 1. The anti-expansion component improves the strength of the wall panel body 1, making it less prone to excessive deformation when pouring concrete or other grout. This reduces the need for chiseling and repairing the wall panel body 1 due to irregular shape after the grout solidifies, thus reducing construction costs. Simultaneously, at least one of the top, side, and bottom of the wall panel body 1 is provided with the finishing layer 3. The finishing layer 3 integrates installation and decoration of the prefabricated lightweight wall panel. After installation, no secondary painting is required, saving the cost of painting and further reducing construction costs. The avoidance arrangement of the finishing layer 3 and the anti-expansion component means that the arrangement of the finishing layer 3 and the anti-expansion component does not affect the realization of their respective functions.

[0011] The anti-expansion component is located inside and / or outside the wall panel body 1. This means that the anti-expansion component can be located outside the wall panel body 1, and / or, at a position between the outside of the cavity and the inside of the wall panel body 1, and / or, at a position inside the cavity. Specifically, for example, the anti-expansion component includes a first anti-expansion unit located inside the cavity, and a second anti-expansion unit located outside the wall panel body 1. The second anti-expansion unit is located at least on the inner and / or outer side of the wall panel body 1, and the second anti-expansion unit is disposed to avoid contact with the finishing layer 3.

[0012] The first and second anti-expansion units can be specifically structures such as steel plates, steel mesh frames, steel trusses, or fiber layers made of polypropylene fibers or glass fibers. The "assembly" in prefabricated lightweight precast wall panels refers to the fact that each structure of the prefabricated lightweight precast wall panel can be manufactured separately and then assembled together on the construction site. Transportation from the workshop to the construction site can be done in batches, reducing the space occupied during transportation of the assembled structures. The "lightweight" in prefabricated lightweight precast wall panels refers to the fact that each structure is manufactured separately, allowing operators to handle it individually without the need for large lifting machinery such as cranes. Furthermore, each structure of the prefabricated lightweight precast wall panel can be made of lightweight materials; for example, the concrete poured into the cavity can be made of lightweight materials. Lightweight porous aggregate concrete, wall panel main body 1 and other structures can be designed with perforations to reduce weight without affecting strength and aesthetics. Wall panel main body 1 and anti-expansion components can be made of materials with sufficient strength but low density, such as aluminum alloy, polyurethane foam, or carbon fiber reinforced composite materials with fiber as reinforcement and resin, metal, ceramic, etc. as matrix material. Prefabrication in assembled lightweight precast wall panels means that except for the pouring of concrete and other grout, other structures can be manufactured in the workshop in advance, thus saving the cost of on-site processing equipment.

[0013] Alternatively, the first and second anti-expansion units may not adopt the structure described above. For example, the first anti-expansion unit includes an anti-expansion frame 4 that is attached to the wall panel body 1. The anti-expansion frame 4 includes several first supports 5 and several second supports 6. The first supports 5 and the second supports 6 are arranged in opposite directions and are connected. Each of the first supports 5 and the second supports 6 is provided with a slurry channel connected to the inlet 2. Adjacent slurry channels are connected. Figures 1-8 As shown, the shape of the molding slurry 17 is the same as that of the anti-expansion frame 4 and the cavity of the wall panel body 1; the opposite orientation means that the first support 5 and the second support 6 are set in different directions, and there is an angle between them, such as Figures 1-8 As shown, the angle between the first support 5 and the second support 6 is 90°. At this time, the first support 5 and the second support 6 are hollow cylindrical structures. Alternatively, the angle between the first support 5 and the second support 6 can be other angles, as long as the angle between the first support 5 and the second support 6 does not affect the construction of the building and can improve the strength of the wall panel body 1 and reduce the expansion and deformation of the wall panel body 1 after pouring concrete and other grout.

[0014] like Figure 2 , Figure 4 , Figure 6 As shown, in this utility model, an assembled lightweight prefabricated wall panel including an insulation layer and / or one or two sets of third and fourth connecting members, the top and / or bottom of the first support 5 is provided with a grout injection port communicating with the grout channel. The first support 5 is connected to the second support 6. Therefore, if a grout injection port is provided on the first support 5, a grout injection port is not required on the second support 6. To improve grouting efficiency, grout injection ports can be provided on both sides of the second support 6. No through holes are provided in other areas of the first support 5 and the second support 6 except for the grout injection ports. Figure 20 As shown, the first support 5 and the second support 6 are uniformly provided with several through holes. The diameter of the through holes is smaller than the diameter of the grout flow hole. This prevents the poured grout from flowing out of the through holes, ensuring that the grout injected into the anti-expansion frame 4 can be smoothly formed. The distribution density of the through holes on the first support 5 and the second support 6 depends on the working conditions. At the same time, the through holes provide a certain deformation space for the anti-expansion frame 4. When the anti-expansion frame 4 is subjected to external forces such as grout, it can release stress through the slight expansion or bending deformation of the area around the through holes. In other words, the through holes provide a "buffer zone" for the local deformation of the anti-expansion frame 4, reducing the probability of stress concentration causing the anti-expansion frame 4 to break, improving the elasticity and deformation resistance of the anti-expansion frame 4, and further improving the anti-expansion capability of the prefabricated lightweight wall panel.

[0015] The cavity contains a first and a second reinforcing member that are connected and arranged in opposite directions. The first and second reinforcing members can be located within the anti-expansion frame 4, forming a reinforcing frame that can withstand tensile, shear, and compressive forces in multiple directions, effectively improving the strength of the wall panel body 1. The first and second reinforcing members can be connected by welding, riveting, or binding. The first and second reinforcing members can be made of steel bars, steel plates, fiber rods, or other structures of different shapes and materials that can improve the strength of the wall panel body 1.

[0016] And / or, the second anti-expansion unit includes a first anti-expansion component 7 and a second anti-expansion component 8. The first anti-expansion component 7 is located on the side of the second anti-expansion component 8 closer to the wall panel body 1. A first connecting unit is provided between the first anti-expansion component 7 and the second anti-expansion component 8. The first connecting unit includes an adhesive provided between the first anti-expansion component 7 and the second anti-expansion component 8, and a first connector and a second connector 9 respectively provided on opposite sides of the first anti-expansion component 7 and the second anti-expansion component 8. The first connector and the second connector 9 can form a connecting pair that avoids the adhesive layer. By assembling the first anti-expansion component 7, the second anti-expansion component 8 and the wall panel body 1 together, the strength of the wall panel body 1 can be effectively improved and the deformation of the wall panel body 1 during concrete pouring can be reduced. The first anti-expansion component 7 can specifically be an anti-expansion plate, or an anti-expansion sheet, or an anti-expansion block, or a lightweight skeleton formed by cross-laid steel bars, etc., provided on the wall panel body 1. The first anti-expansion component 7 and the wall panel body 1 can be bonded together by adhesive grout or fixed together by fasteners such as bolts. Depending on the different materials of the first anti-expansion component 7 and the second anti-expansion component 8, the adhesive layer can be made of materials that can play an adhesive bonding role, such as polyurethane adhesive or cement-based slurry. Furthermore, the first anti-expansion component 7 and the second anti-expansion component 8 are also connected together by a connecting pair, which improves the connection strength between the first anti-expansion component 7 and the second anti-expansion component 8. This effectively reduces the problem that when the first anti-expansion component 7 and the second anti-expansion component 8 are connected by the adhesive layer alone, due to the different materials of the first anti-expansion component 7 and the second anti-expansion component 8, the deformation amount due to thermal expansion and contraction is different, which may cause some areas of the first anti-expansion component 7 and the second anti-expansion component 8 to separate, thus reducing the connection strength of the first anti-expansion component 7 and the second anti-expansion component 8. Specifically, the first anti-expansion component 7 and the second anti-expansion component 8 can be connected by bolts, or by a male and female groove combination, or by a tenon and mortise combination, etc.

[0017] In addition to the above-mentioned forms and materials, the first anti-expansion unit and the second anti-expansion unit may also be other forms made of other materials, which can improve the strength of the wall panel body 1 and reduce the expansion and deformation of the wall panel body 1 after pouring concrete or other grout.

[0018] like Figure 13 , Figure 14As shown, the second anti-expansion member 8 has a plurality of second connecting members 9 spaced apart in at least two directions on the side facing the first anti-expansion member 7. (For example, if the second anti-expansion member 8 has a plurality of second connecting members 9 distributed in the transverse and longitudinal directions on the side facing the first anti-expansion member 7, then the side facing the first anti-expansion member 7 of the second anti-expansion member 8 has multiple rows and columns of second connecting members 9, and adjacent second connecting members 9 are spaced apart; or, the side facing the first anti-expansion member 7 of the second anti-expansion member 8 has multiple rings of second anti-expansion members 8, with gaps between adjacent rings, each ring including a plurality of second anti-expansion members 8 arranged circumferentially and spaced apart, the multiple rings of second anti-expansion members 8 are equivalent to multiple concentric circles arranged on the second anti-expansion member 8, thus, by controlling the gap between each ring and the number of second anti-expansion members in the same ring...) The spacing between the second anti-expansion members 8 (which can adjust the connection strength of the adhesive layer) forms a channel for injecting adhesive on the side of the second anti-expansion member 8 facing the first anti-expansion member 7, with the gap between adjacent second connectors 9. The channel includes a third channel and a fourth channel that are connected and are arranged in opposite directions. Since the first connector on the first anti-expansion member 7 and the second connectors 9 on the second anti-expansion member 8 are distributed at least in multiple intervals in two directions, the adhesive layer formed by curing between the first anti-expansion member 7 and the second anti-expansion member 8 has a large force-bearing area in multiple directions, such as the transverse and longitudinal directions. This improves the adhesive layer's resistance to pressure and tension forces in multiple directions and further improves the connection strength between the first anti-expansion member 7 and the second anti-expansion member 8.

[0019] like Figure 13 , Figure 14 As shown, the second connecting member 9 is a locking block, and the first connecting member on the first anti-expansion member 7 is a locking groove that cooperates with the locking block and can be locked together with the locking block. Figure 9 , Figure 11 As shown, the width of the finishing layer 3 is smaller than the width of the wall panel body 1, which facilitates the placement of subsequent reinforcing structures such as trusses between adjacent wall panel bodies 1.

[0020] And / or, when a second anti-expansion unit is provided on the same side of the wall panel body 1, the finishing layer 3 and the second anti-expansion unit are provided, the second anti-expansion component 8 is located on the side of the finishing layer 3 close to the wall panel body 1, and the side of the second anti-expansion component 8 facing away from the wall panel body 1, that is, the side facing the finishing layer 3, is a flat surface. Specifically, according to the unevenness of the first anti-expansion component 7 and the wall panel body 1, the side of the second anti-expansion component 8 facing the finishing layer 3 can be polished and adjusted so that there are no protruding or recessed areas on the side of the second anti-expansion component 8 facing the finishing layer 3, and all are flat areas. This helps to maintain the flatness and aesthetics of the finishing layer 3, reduces the steps required for secondary beautification of the finishing layer 3 by operators, and reduces construction costs.

[0021] The prefabricated lightweight wall panel also includes an insulation layer 10 disposed on the outside of the wall panel body 1. The insulation layer 10 improves the thermal insulation performance of the prefabricated lightweight wall panel and reduces the heating cost in the building. The insulation layer 10 can be made of materials with thermal insulation properties such as polystyrene or polyurethane. When the prefabricated lightweight wall panel is used as an exterior wall panel, the insulation layer 10 can be disposed on the outside of the wall panel body 1, i.e., the side away from the interior. It should be noted that the insulation layer 10 is disposed separately from the finishing layer 3 and the anti-expansion component to prevent their respective functions from being interfered with. For example, the insulation layer 10 and the finishing layer 3 can be disposed sequentially from the outside to the inside on the outside of the wall panel body 1, or the insulation layer 10 and the finishing layer 3 can be laid flat on the wall panel body 1. For example, if the user has high requirements for aesthetics and insulation, and requests that a finishing layer 3 be installed on both the inner and outer sides of the wall panel body 1, then a finishing layer 3 will be installed on both the inner and outer sides of the wall panel body 1, and an insulation layer 10 will be installed between the finishing layer 3 and the wall panel body 1; if the user has lower requirements for insulation, then an insulation layer 10 and a finishing layer 3 can be installed only on the outer side of the wall panel body 1 from the inside out, and a second anti-expansion component 8 and a finishing layer 3 can be installed on the inner side of the wall panel body 1 from the outside in. Figure 9 , Figure 11 As shown, the insulation layer 10 and the second anti-expansion component 8 can be connected together by means of a slot and a block.

[0022] When the wall panel body 1 is provided with an insulation layer 10 and a finishing layer 3 on the outer side, the insulation layer 10 is located between the finishing layer 3 and the second anti-expansion unit, and a second connecting unit 18 is provided between the insulation layer 10 and the finishing layer 3. The second connecting unit 18 is used to connect the insulation layer 10 and the finishing layer 3 together. The second connecting unit 18 includes an adhesive layer formed by polyurethane glue or cement-based slurry, and / or, the second connecting unit 18 includes fasteners such as bolts for fixing the finishing layer 3 and the insulation layer 10 together.

[0023] And / or, the finishing layer 3 can be a metallic finishing layer or a non-metallic finishing layer. For example, the finishing layer 3 can be a structural layer made of materials with aesthetic effects such as latex paint, ceramic tile 20, or paint; when the prefabricated lightweight wall panel is used as an exterior wall panel, the finishing layer 3 located on the outside of the wall panel body 1 is an anti-aging finishing layer 3, that is, in addition to having an aesthetic effect, the finishing layer 3 also has the effect of resisting ultraviolet aging. In this case, such as Figures 5-8 As shown, the finishing layer 3 includes a plurality of ceramic tiles 20 and a fixing component 21 for connecting the ceramic tiles 20 together and fixing them to the insulation layer 10. The fixing component 21 includes fasteners 31 and fixing plates 32. The fasteners 31 may be bolts or other structures. Alternatively, the finishing layer 3 may be made of aluminum plates or fluorocarbon paint or other materials that can resist ultraviolet aging.

[0024] Furthermore, the prefabricated lightweight wall panel includes a sealing assembly, which includes a first sealing element 33, a second sealing element, and a third sealing element. The first sealing element 33 is located at the entrance, and the second and third sealing elements are respectively located at the entrances 2 on opposite or adjacent sides of the wall panel body 1, so that the second and third sealing elements on opposite sides of the adjacent wall panel body 1 can form a sealing pair, which is located inside or outside of the first sealing element 33. The first sealing element 33 can specifically be a sealing ring or other structure that can achieve a sealing effect. The second and third sealing elements can specifically refer to the male and female grooves respectively located at the entrances 2 on opposite sides of the wall panel body 1, or they can be understood as tenons and mortises, etc., that can connect adjacent wall panel bodies 1 together and achieve a sealing effect. By using the above-mentioned sealing assembly, the problem of leakage of grout from the entrance 2 during the injection of concrete or other grout into the cavity and the soiling of the finishing layer 3 and other areas of the wall panel body 1 is reduced, thus ensuring the aesthetics of the prefabricated lightweight wall panel and reducing construction costs.

[0025] And / or, the sealing assembly also includes a receiving area 11 disposed on the opposite side of the adjacent wall panel body 1 for receiving adhesive; the receiving area 11 includes the opposite surface of the adjacent wall panel body 1, and an adhesive such as anti-crack slurry that can achieve the bonding effect is applied to the opposite surface of the adjacent wall panel body 1; and / or, the receiving area 11 includes a groove on the opposite surface of the adjacent wall panel body 1, the groove may be a slot opened on the wall panel body 1, and / or, a plurality of protrusions are provided on the opposite surface of the adjacent wall panel body 1, in which case the receiving area 11 is the area between adjacent protrusions, i.e., the groove between adjacent protrusions; by receiving adhesive through the receiving area 11, and / or storing excess adhesive, the excessive overflow of adhesive on the surface of the wall panel body 1 is reduced, reducing the damage to the finishing layer 3, thus avoiding the problem that operators need to perform secondary repairs on the finishing layer 3 after installing the assembled lightweight prefabricated wall panels, which increases construction costs.

[0026] The prefabricated lightweight wall panel includes a connecting component 19; wherein, the connecting component 19 includes a first connecting area 25 and a second connecting area 26 disposed on the wall panel body 1, the first connecting area 25 and the second connecting area 26 being arranged opposite to or adjacent to each other, and adjacent wall panel bodies 1 being connected through the first connecting area 25 and the second connecting area 26; for example Figure 9 , Figure 11 As shown, the first connection area 25 and the second connection area 26 can be tenons and mortises that fit together, or the first connection area 25 and the second connection area 26 can both be bolt holes, through which bolts pass in sequence to connect adjacent wall panel bodies 1 together; or the first connection area 25 and the second connection area 26 can be an adhesive layer coated on the wall panel body 1; the setting of the first connection area 25 and the second connection area 26 should not affect the overall aesthetics of the finishing layer 3, i.e., the prefabricated lightweight wall panel.

[0027] And / or, such as Figures 15-18 As shown, the connecting assembly 19 includes several third connectors 12 and several fourth connectors 13 passing through the cavity. The third connectors 12 and fourth connectors 13 are connected and arranged in opposite directions, with both ends of the third connectors 12 and fourth connectors 13 extending out of the wall panel body 1. Adjacent wall panel bodies 1 are connected by opposite third connectors 12 or by opposite fourth connectors 13. The third connectors 12 and fourth connectors 13 can form a skeleton structure, which can withstand tensile, shear, and compressive forces in multiple directions, effectively improving the strength of the wall panel body 1. The third connectors 12 and fourth connectors 13 can be steel bars, steel plates, fiber rods, or screws, etc., which can improve the strength of the wall panel body 1 and realize the connection between adjacent wall panel bodies 1. The third connectors 12 and fourth connectors 13 can be connected by welding, riveting, or binding, etc. Figure 15 , Figure 16 As shown, at this time, both the third connector 12 and the fourth connector 13 can be steel threaded rods. Only one set of each type of connector is provided, i.e., one row of third connectors 12 and one row of fourth connectors 13. The third connectors 12 and fourth connectors 13 can be welded together. Each fourth connector 13 passes through the first limiting hole 23 of the limiting member 22 and is fixed to the limiting member 22 by fasteners such as nuts 16. The limiting member 22 is snapped into the entrance 2 by flanges on both sides. The limiting member 22 can also be fixed by adhesives or other methods. The fourth connecting piece 13 is fixed at entrance 2 because the limiting member 22 is fixed at entrance 2. The third connecting piece 12 and the fourth connecting piece 13 are fixedly connected. Thus, the limiting member 22 achieves the fixation of the third connecting piece 12 and the fourth connecting piece 13, reducing the displacement of the third connecting piece 12 and the fourth connecting piece 13 during the concrete pouring process, and avoiding the situation where the third connecting piece 12 and the fourth connecting piece 13 scratch the wall panel body 1. The limiting member 22 can be a connecting bracket or other structure that can fix the third connecting piece 12 and / or the fourth connecting piece 13.

[0028] like Figure 17 , Figure 18As shown, the third connector 12 and the fourth connector 13 are provided in two sets, namely two rows of third connector 12 and two columns of fourth connector 13. The third connector 12 and the fourth connector 13 are fixed together by the mounting member 27. The mounting member 27 is provided with a first mounting hole 28. The mounting member 27 is fixed in the wall panel body 1 by bolts, screws and other fastening structures. The third connector 12 passes through the second mounting hole 29, and the mounting ring 30 is sleeved on the fourth connector 13, thereby improving the integrity of the third connector 12 and the fourth connector 13 and improving the deformation resistance of the skeleton structure formed by the third connector 12 and the fourth connector 13. At this time, the two columns of fourth connector 13 are respectively passed through the second limiting hole 24 of the limiting member 22. Moreover, the number of third connector 12 and fourth connector 13 is not limited to one row or two rows as mentioned above. More third connector 12 and fourth connector 13 can be set, or the number of third connector 12 in a single row or the number of fourth connector 13 in a single column can be reduced.

[0029] And / or, the two ends of the third connector 12 are respectively provided with a first connecting portion 14 and a first guiding portion 15, and the opposite third connectors 12 of adjacent wall panel bodies 1 are connected through the corresponding first connecting portion 14 and first guiding portion 15. The first guiding portion 15 is used for guiding the connection between adjacent third connectors 12, i.e., the first connecting portion 14 and the first guiding portion 15; and / or, the two ends of the fourth connector 13 are respectively provided with a second connecting portion and a second guiding portion, and the opposite fourth connectors 13 of adjacent wall panel bodies 1 are connected through the corresponding second connecting portion and second guiding portion. The second guiding portion is used for guiding the connection between adjacent fourth connectors 13, i.e., the second connecting portion and the second guiding portion. Figures 15-18 As shown, the second connecting part can specifically be an externally threaded section provided on the first end of the fourth connecting member 13. In this case, the second guiding part can be a guide cylinder, i.e., a nut cap with a flared opening, provided on the second end of the fourth connecting member 13, which is connected to the externally threaded section through the nut cap; or the second guiding part can also be a guide protrusion or guide groove provided on the second end of the fourth connecting member 13. The guide protrusion or guide groove can be provided along the axial direction of the fourth connecting member 13, and a guide groove or guide protrusion that mates with it is provided on the first end of the fourth connecting member 13. The first guiding part 15 is provided in the same way as the second guiding part, and can also be a guide cylinder, i.e., a nut cap with a flared opening, provided on the second end of the third connecting member 12. In this case, the first end of the third connecting member, i.e., the first connecting part 14, is an externally threaded section that mates with the first guiding part 15.

[0030] The shapes of the finishing layer 3, insulation layer 10, first anti-expansion component, second anti-expansion component 8, and second connecting unit 18 in this article are adjusted according to the shape of the wall panel body 1. For example, when the wall panel body 1 is a plate-shaped structure, all of the above structures can be plate-shaped structures. In this article, the outer side of the wall panel body 1 refers to the side of the wall panel body 1 away from the interior, and the inner side of the wall panel body 1 refers to the side of the wall panel body 1 closer to the interior.

[0031] The term "several" in this article can be understood as "N," specifically referring to at least one.
