[0025] 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.

[0026] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0027] like Figure 1-5 As shown, this utility model provides a prefabricated insulated wall panel, which includes multiple panels and compressed steel bars; the multiple panels include a first panel 1 and a second panel 2 arranged opposite to each other; a first cavity is formed between the first panel 1 and the second panel 2; and an insulation material 3 is disposed in the first cavity.

[0028] The aforementioned thermal insulation material 3 has a third plate 4 on the side near the first plate 1; a second cavity is formed between the first plate 1 and the third plate 4; a first compression steel bar 5 with a preset height value is provided at the bottom of the second cavity; the first compression steel bar 5 is spirally distributed in the second cavity along a first preset direction; the first preset direction is parallel to the setting direction of the first plate 1; the ratio between the preset height value and the height value of the first plate 1 is a preset ratio value; the side of the first compression steel bar 5 near the first plate 1 abuts against the first plate 1; the side of the first compression steel bar 5 near the third plate 4 abuts against the third plate 4; the compression steel bar includes the first compression steel bar 5.

[0029] In some embodiments, the insulation material 3 can be polyurethane insulation material; the preset height value can be 450mm; the first compressed steel bar 5 can be a compressed curved hoop with a diameter of 3mm; the first preset direction can be vertical; the first panel 1 and the second panel 2 are the outer surfaces of the prefabricated insulation wall panel, exposed to the external environment. Therefore, the first panel 1 and the second panel 2 have waterproof, moisture-proof, and weather-resistant properties to protect the internal structure of the prefabricated insulation wall panel from the influence of the external environment. The first panel 1 and the second panel 2 can be metal, composite materials, or other weather-resistant materials. The insulation material 3 is disposed in the first cavity between the first panel 1 and the second panel 2, ensuring the insulation performance of the prefabricated insulation wall panel. The third panel 4 is the inner panel of the prefabricated insulation wall panel, used to isolate the first compressed steel bar 5 from the insulation material 3, and the first compressed steel bar 5 is disposed in the second cavity formed between the first panel 1 and the third panel 4. The first compressed steel bar 5 starts from the bottom of the second cavity and spirals upwards until it stops at a position 450mm away from the bottom of the second cavity. One end of the compression hoop abuts against the first panel surface 1, and the other end abuts against the third panel surface 4, thus reinforcing the precast insulated wall panel. Simultaneously, assuming the height of the precast insulated wall panel is fixed at A mm, the ratio between the height of the first compression reinforcement 5 and the height of the first panel surface 1, i.e., the preset ratio, is fixed at 450 / A. By setting the first compression reinforcement at the bottom of the precast insulated wall panel, the shear resistance of the precast insulated wall panel in the bottom area is effectively improved, and the horizontal displacement of the precast insulated wall panel is restricted, ensuring the overall stability of the wall adjacent to the precast insulated wall panel, enhancing the stability and connection strength of the precast insulated wall panel, and extending its service life.

[0030] In other embodiments, the preset height value and the first compressed steel bar 5 can be set according to the actual situation.

[0031] In this utility model, the insulation material 3 is provided with a fourth plate 6 on the side close to the second plate 2; a third cavity is formed between the second plate 2 and the fourth plate 6; a second compression steel bar 7 with the preset height value is provided at the bottom of the third cavity; the second compression steel bar 7 is spirally distributed in the third cavity along the first preset direction; the compression steel bar includes the second compression steel bar 7.

[0032] In some embodiments, such as Figure 2 As shown, the preset height value can be 450mm, the second compression steel bar 7 can be a compression hoop, the first preset direction can be vertical, and the compression hoop is spirally distributed within a 450mm height range at the bottom of the third cavity; the side of the compression hoop near the second panel 2 abuts against the second panel 2, and the side near the fourth panel 6 abuts against the fourth panel 6, thus the compression hoop is fixedly set in the third cavity. The first compression steel bar 5 and the second compression steel bar 7 are symmetrically distributed along the central axis of the side of the precast insulation wall panel. By setting the second compression steel bar in the third cavity, the lateral movement of the precast insulation wall panel is effectively restricted, ensuring the overall stability of the wall adjacent to the precast insulation wall panel, significantly improving the shear resistance of the precast insulation wall panel, enhancing the connection strength between the precast insulation wall panel and adjacent wall panels, and extending the service life of the precast insulation wall panel.

[0033] In other embodiments, the preset height value and the second compression steel bar 7 can be set according to the actual situation.

[0034] The first compressed steel bar 5 includes a first compression unit 8 of a first preset number; the first compression unit 8 of the first preset number is distributed at equal intervals in the second cavity.

[0035] The aforementioned second compression steel bar 7 includes a second preset number of second compression units 9; the aforementioned second preset number of second compression units 9 are distributed at equal intervals within the aforementioned third cavity.

[0036] In some embodiments, such as Figure 2 As shown, the first preset quantity and the second preset quantity can be the same, both being 9; both the first compression unit 8 and the second compression unit 9 are compression hoops with a height of 50mm. Users can increase or decrease the quantity of the first compression unit 8 or the second compression unit 9 according to the area to be reinforced. By setting the first compression unit and the second compression unit, uniform constraint force and shear strength are provided for the prefabricated insulation wall panel, ensuring that the wall adjacent to the prefabricated insulation wall panel remains stable under various external forces, and the reinforcement effect of specific areas can be improved in a targeted manner.

[0037] In other embodiments, the first preset quantity and the second preset quantity can be set according to actual conditions.

[0038] In this utility model, a stable area 10 is provided between every two adjacent panels; the stable area 10 is provided on the side of the prefabricated insulated wall panel close to the wall; and a concrete hidden column is provided in the stable area 10.

[0039] In some embodiments, such as Figure 4-5 As shown, the stable zone 10, also known as the edge concealed column zone, consists of hidden reinforced concrete columns installed on both sides or at corners of the wall. These columns serve as reinforcing members, providing additional support to the wall edges and limiting lateral displacement. The stable zone enhances the shear resistance of the wall adjacent to the precast insulation wall panel, ensuring its overall stability. This allows for a more even distribution of shear force within the wall adjacent to the precast insulation wall panel, preventing localized stress concentration and reducing cracks or damage caused by uneven stress distribution.

[0040] In this utility model, each of the above-mentioned plate surfaces includes multiple longitudinal steel bars and multiple transverse steel bars 11; the multiple longitudinal steel bars are arranged along the first preset direction and are distributed at equal intervals on each of the above-mentioned plate surfaces; the multiple transverse steel bars 11 are arranged along the second preset direction on each of the above-mentioned plate surfaces; the second preset direction is perpendicular to the first preset direction.

[0041] In some embodiments, such as Figure 3-5 As shown, the first preset direction can be vertical; the second preset direction can be horizontal; the first panel 1 and the second panel 2 are the outer panels of the precast insulated wall panel. Both the first panel 1 and the second panel 2 are provided with longitudinal and transverse reinforcing bars 11, which are welded to the first panel 1 and the second panel 2 to form a grid. The longitudinal reinforcing bars effectively resist tensile forces, preventing excessive deflection of the wall adjacent to the precast insulated wall panel due to compression or tension. The transverse reinforcing bars limit the lateral displacement of the wall adjacent to the precast insulated wall panel, ensuring the safety of the building. The combined use of longitudinal and transverse reinforcing bars enhances the connection strength between the wall and other components, ensuring that the wall will not loosen or fall off when subjected to vertical and horizontal loads, extending the service life of the precast insulated wall panel, and ensuring the safety of the wall structure.

[0042] In this utility model, the longitudinal reinforcement includes longitudinal structural reinforcement 12; the longitudinal structural reinforcement 12 penetrates each of the above-mentioned plate surfaces along the first preset direction.

[0043] In some embodiments, such as Figure 1As shown, the first preset direction can be vertical. Both the first panel 1 and the second panel 2 are outer panels of the precast insulated wall panel. The longitudinal structural reinforcement 12 is set along the height direction of the outer panel and can be HRB400 or HRB500 grade hot-rolled ribbed steel bars with a diameter of 8mm to 12mm. The longitudinal structural reinforcement 12 penetrates the outer panel, extending from the top to the bottom. By setting the longitudinal structural reinforcement, the bending stiffness of the precast insulated wall panel is significantly improved, effectively resisting bending deformation, enhancing the overall integrity of the precast insulated wall panel, and extending its service life.

[0044] The longitudinal reinforcement includes longitudinal connecting bars 13; one end of the longitudinal connecting bar 13 is connected to the longitudinal connecting bar of the first adjacent outer wall panel; the other end of the longitudinal connecting bar 13 is connected to the longitudinal connecting bar of the second adjacent outer wall panel; the first adjacent outer wall panel and the second adjacent outer wall panel are both outer wall panels adjacent to the prefabricated insulated wall panel along the first preset direction; the prefabricated insulated wall panel is disposed between the first adjacent outer wall panel and the second adjacent outer wall panel.

[0045] In some embodiments, such as Figure 1 As shown, prefabricated insulated wall panels are arranged side-by-side vertically, with longitudinal connecting ribs 13 used to connect adjacent panels. The longitudinal connecting ribs 13 are arranged in two types: in the unstable areas of the prefabricated insulated wall panels, the distance between two adjacent longitudinal connecting ribs 13 is less than or equal to 800 mm; in the stable areas 10 of the prefabricated insulated wall panels, the distance between two adjacent longitudinal connecting ribs 13 is less than or equal to 250 mm. By setting longitudinal connecting ribs on the prefabricated insulated wall panels, the overall integrity between adjacent panels is enhanced. Furthermore, the smaller spacing of the longitudinal connecting ribs in the stable areas significantly improves the shear stiffness of the stable areas, preventing shear failure of the prefabricated insulated wall panels under horizontal external forces, thus improving the durability and structural safety of the prefabricated insulated wall panels.

[0046] The prefabricated insulated wall panel also includes multiple truss bars 14; one end of the truss bar 14 is connected to the longitudinal structural bar 12 on the first panel 1; the other end of the truss bar 14 is connected to the longitudinal structural bar 12 on the second panel 2.

[0047] In some embodiments, such as Figure 3-4As shown, the truss reinforcement 14 can be a steel bar with a diameter of 6mm, and the spacing between two adjacent truss reinforcements 14 is 100mm; the first plate surface 1 and the second plate surface 2 are both outer plates of the precast insulation wall panel. The truss reinforcement 14 connects the two adjacent outer plates in the horizontal direction, which significantly improves the shear resistance of the precast insulation wall panel, makes the shear force more evenly distributed in the wall, avoids local stress concentration, reduces cracks or damage to the precast insulation wall panel caused by uneven stress, enhances the bending stiffness of the precast insulation wall panel, improves the seismic performance of the precast insulation wall panel, and improves the integrity and connection strength of the precast insulation wall panel.

[0048] In other embodiments, the dimensions of the truss reinforcement 14 can be set according to the actual situation.

[0049] In this utility model, a fixing element 15 is provided on the side of the prefabricated insulated wall panel away from the wall; the fixing element 15 is fixedly connected to the transverse steel bar 11.

[0050] In some embodiments, such as Figure 3-5 As shown, the fixing element 15 is a double-strand tie wire, which is formed by twisting two thin steel wires into one strand. It is set on the side of the precast insulation wall panel away from the wall, and the double-strand tie wire firmly binds the longitudinal reinforcement, transverse reinforcement 11, and truss reinforcement 14 together to form an integral steel reinforcement skeleton. By setting the fixing element, the integrity of the steel reinforcement mesh on the panel surface is ensured, avoiding the degradation of the structural performance of the precast insulation wall panel due to loose reinforcement. This enhances the shear resistance, bending resistance, and seismic resistance of the precast insulation wall panel, extends its service life, and reduces maintenance costs.

[0051] In other embodiments, the fixing element 15 may be configured according to the actual situation.

[0052] In this invention, the aforementioned multiple panels are L-shaped; an L-shaped cavity is formed between every two adjacent panels; and a concrete hidden column is provided at the corner of the L-shaped cavity.

[0053] In some embodiments, such as Figure 5 As shown, the panel can be L-shaped, with adjacent panels tightly connected to form an L-shaped wall panel, and an L-shaped cavity formed between adjacent panels. Concrete hidden columns are set at the corners of adjacent panels, i.e., at the corners of the L-shaped cavities. Since the corners of the L-shaped exterior wall panels are key stress-bearing parts of the wall and are easily subjected to large horizontal external forces, the setting of concrete hidden columns can significantly improve the shear resistance at the corners of the L-shaped prefabricated insulation wall panels, prevent the wall from undergoing shear failure under these external forces, maintain good flatness of the prefabricated insulation wall panels, and extend the service life of the prefabricated insulation wall panels.

[0054] The working principle of this prefabricated insulated wall panel is as follows:

[0055] During the installation of prefabricated insulated wall panels, the wall panels are first hoisted into place and their verticality and flatness are corrected. Then, the steel mesh on the panel surface is fixed using fixing element 15, the longitudinal connecting bar 13 connects the upper and lower wall panels, the longitudinal structural bar 12 enhances the bending stiffness, the truss bar 14 improves the shear strength, the stabilizing area 10 strengthens the stability at the corners, and the compression bar provides additional restraint. Finally, the insulation material 3 is filled to ensure the insulation performance, forming a complete prefabricated insulated wall panel.

[0056] The beneficial effects of this utility model are:

[0057] This utility model discloses a prefabricated insulated wall panel, comprising multiple panels and compressed reinforcing bars. The multiple panels include a first panel and a second panel arranged opposite to each other. A first cavity is formed between the first panel and the second panel. Insulation material is disposed within the first cavity. A third panel is disposed on the side of the insulation material closest to the first panel. A second cavity is formed between the first panel and the third panel. A first compressed reinforcing bar of a preset height is disposed at the bottom of the second cavity. The first compressed reinforcing bar is spirally distributed within the second cavity along a first preset direction. The first preset direction is parallel to the orientation of the first panel. The ratio between the preset height value and the height value of the first panel is a preset ratio value. The side of the first compressed reinforcing bar closest to the first panel abuts against the first panel. The side of the first compressed reinforcing bar closest to the third panel abuts against the third panel. The compressed reinforcing bars include the first compressed reinforcing bars. By placing insulation material in the first cavity formed between the first and second panels, the insulation performance of the prefabricated insulated wall panel is improved. By placing first compression steel bars at the bottom of the second cavity formed between the first and third panels and second compression steel bars at the bottom of the third cavity formed between the second and fourth panels, the structural stability of the prefabricated insulated wall panel is enhanced, and its shear strength is increased. By setting longitudinal and transverse steel bars, the overall stability between adjacent wall panels is improved.

[0058] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
