During installation, the entire panel is mounted on the exterior wall of the building, improving construction efficiency.

[0003] Currently, when prefabricating integrated insulation and decorative wall panels, C-shaped steel is pre-embedded vertically in the inner leaf plate of the integrated wall panel to improve the structural strength of the integrated panel. However, integrated wall panels are usually large-format panels, and the cross-sectional size of the C-shaped steel is relatively small. In the case of large spans, the C-shaped steel is prone to breakage, especially during the transportation of integrated wall panels. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a prefabricated truss structure integrated insulation and decoration wall panel. A truss support body formed by interwoven horizontal and vertical trusses is set in the inner leaf panel. The truss support body of this structure can distribute the force more evenly, improve the load-bearing capacity of the wall panel under large span conditions, effectively reduce the risk of breakage, and also enhance the stability of the wall panel during transportation.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A prefabricated truss structure integrated insulation and decoration wall panel includes an outer leaf plate, an inner leaf plate, and an insulation layer sandwiched between the outer leaf plate and the inner leaf plate. The inner leaf plate is provided with a truss support body spliced ​​by multiple sets of steel trusses. The steel truss includes a first truss and a second truss, which are arranged in a grid pattern. An oblique insert is also provided between the outer leaf plate and the inner leaf plate. One end of the oblique insert is located inside the outer leaf plate, and the other end of the oblique insert passes through the insulation layer and is fixedly connected to the truss support body located inside the inner leaf plate.

[0007] The first truss and the second truss have the same structure. Both the first truss and the second truss include support bars on both sides and reinforcing bars located between the support bars on both sides. The reinforcing bars are arranged in a W-shape between the support bars on both sides.

[0008] The intersection of the first truss and the second truss forms a welded node, which overlaps with the inflection point of the reinforcing rib and is welded and fixed.

[0009] The first truss is arranged in the transverse direction, and the second truss is arranged in the longitudinal direction. The planes where the first truss and the second truss are located are perpendicular to the surface of the wall panel, respectively.

[0010] The outer leaf plate is provided with a wire mesh, and the ends of the inclined ribs are fixedly connected to the wire mesh.

[0011] The end of the inclined insert bar located inside the outer leaf plate is also provided with a limiting bar. The limiting bar and the inclined insert bar together form a hook-shaped structure, and the included angle between the limiting bar and the inclined insert bar is connected to the wire mesh.

[0012] The oblique inserts are arranged in a symmetrical "eight" shape. The oblique inserts on the upper side are inclined downwards from the outer leaf plate to the inner leaf plate, while the oblique inserts on the lower side are inclined upwards from the outer leaf plate to the inner leaf plate.

[0013] The outer leaf plate is made of concrete, lightweight concrete, or lightweight aggregate concrete.

[0014] The material of the inner leaf plate includes any one of gypsum board, calcium silicate board, concrete, lightweight concrete, and lightweight aggregate concrete.

[0015] The insulation layer is made of one or more of the following materials: rock wool, extruded polystyrene board, polystyrene board, foamed cement board, foamed ceramics, and foamed glass.

[0016] The beneficial effects of this utility model are:

[0017] This utility model uses a truss support to replace C-shaped steel. The truss support in this utility model adds a transverse truss to the traditional single longitudinal truss. The truss support formed by the interweaving of the transverse and longitudinal trusses can distribute the force more evenly, which greatly improves the load-bearing capacity of the wall panel under large span conditions, effectively reduces the risk of breakage, and also enhances the stability of the wall panel during transportation.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] Specific embodiment 1, such as Figure 1-3 As shown, a prefabricated truss structure integrated insulation and decoration wall panel includes an outer leaf plate 1, an inner leaf plate 2, and an insulation layer 3 sandwiched between the outer leaf plate 1 and the inner leaf plate 2. The inner leaf plate 2 is provided with a truss support body 4 composed of multiple sets of steel trusses spliced ​​together. The steel truss includes a first truss 5 and a second truss 6, which are arranged in a grid pattern. An oblique insert 11 is also provided between the outer leaf plate 1 and the inner leaf plate 2. One end of the oblique insert 11 is located inside the outer leaf plate 1, and the other end of the oblique insert 11 passes through the insulation layer 3 and is fixedly connected to the truss support body 4 located inside the inner leaf plate 2.

[0025] Currently, when prefabricating integrated insulation and decorative wall panels, C-shaped steel is pre-embedded in the inner leaf plate 2 of the integrated wall panel along the vertical direction to improve the structural strength of the integrated panel. However, integrated wall panels are usually large-format panels, and the cross-sectional dimensions of the C-shaped steel are relatively small. In the case of large spans, the C-shaped steel is prone to breakage, especially during the transportation of the integrated wall panel.

[0026] Therefore, this utility model uses a truss support body 4 to replace the C-shaped steel. The truss support body 4 in this utility model adds a transverse truss on the basis of the traditional single longitudinal truss. The truss support body 4 formed by the interweaving of the transverse and longitudinal trusses can distribute the force more evenly, which greatly improves the load-bearing capacity of the wall panel under large span conditions, effectively reduces the risk of breakage, and also enhances the stability of the wall panel during transportation.

[0027] The first truss 5 and the second truss 6 have the same structure. Both the first truss 5 and the second truss 6 include support ribs 7 on both sides and reinforcing ribs 8 located between the support ribs 7 on both sides. The reinforcing ribs 8 are arranged in a W-shape between the support ribs 7 on both sides. The W-shaped reinforcing ribs 8 increase the bending resistance of the first truss 5 and the second truss 6, making the mechanical properties of the truss support body 4 more consistent in all directions, further optimizing the stress distribution of the truss support body 4, and improving the overall structural strength and stability of the wall panel.

[0028] The intersection of the first truss 5 and the second truss 6 forms a welded node 9. The welded node 9 overlaps with the inflection point of the reinforcing rib 8 and is welded and fixed. The overlapping welding of the welded node 9 with the inflection point enhances the firmness of the connection between the first truss 5 and the second truss 6, making the overall structure of the truss support 4 more stable, thereby improving the structural strength and reliability of the wall panel.

[0029] The first truss 5 is arranged in the transverse direction, and the second truss 6 is arranged in the longitudinal direction. The planes of the first truss 5 and the second truss 6 are perpendicular to the surface of the wall panel, respectively. This structure forms a two-way steel reinforcement support system with more stress points. When the wall panel is subjected to external forces, both transverse and longitudinal forces can be effectively transmitted and dispersed through the corresponding trusses, enabling the wall panel to better withstand various loads and improve the overall load-bearing capacity of the structure.

[0030] A wire mesh 10 is provided inside the outer leaf plate 1, and the end of the inclined rib 11 is fixedly connected to the wire mesh 10. By providing the wire mesh 10, the structural strength of the outer leaf plate 1 itself is enhanced, and a fixing point is provided for the inclined rib 11.

[0031] The end of the inclined insert rib 11 located inside the outer leaf plate 1 is also provided with a limiting rib 12. The limiting rib 12 and the inclined insert rib 11 together form a hook-shaped structure. The included angle between the limiting rib 12 and the inclined insert rib 11 is engaged with the wire mesh 10. The hook-shaped structure and the engagement with the connecting mesh play a positioning role, which facilitates the binding and fixing of the inclined insert rib 11 and the wire mesh 10. At the same time, it increases the degree of connection between the inclined insert rib 11 and the outer leaf plate 1, and improves the overall structural strength and integrity of the wall panel.

[0032] The inclined insert 11 is arranged in a symmetrical "V" shape. The inclined insert 11 on the upper side is inclined downward from the outer leaf plate 1 to the inner leaf plate 2, and the inclined insert 11 on the lower side is inclined upward from the outer leaf plate 1 to the inner leaf plate 2. This arrangement of the inclined insert 11 can better resist the action of external forces in different directions, and improve the stability and load-bearing capacity of the wall panel.

[0033] The outer leaf plate 1 is made of concrete, lightweight concrete or lightweight aggregate concrete. The outer leaf plate 1 can be shaped directly during the pouring process to form an exterior finish, or after the outer leaf plate 1 is formed, paint can be applied to the outside of the outer leaf plate 1 to form an exterior finish.

[0034] The material of the inner leaf plate 2 includes any one of gypsum board, calcium silicate board, concrete, lightweight concrete, and lightweight aggregate concrete. A keel can be hung on the truss support 4 of the inner leaf plate 2, and the gypsum board can be fixed to the inner side of the inner leaf plate 2 using the keel to form the interior surface. Alternatively, the interior surface can be formed directly during the pouring process.

[0035] The insulation layer 3 is made of one or more of the following materials: rock wool, extruded polystyrene board, polystyrene board, foamed cement board, foamed ceramics, and foamed glass.

[0036] Specific embodiment 2, such as Figure 4As shown, the difference between specific embodiment 2 and specific embodiment 1 is only in the structure of the first truss 5. The first truss 5 includes only two sets of support ribs 7. The two sets of support ribs 7 of the first truss 5 are distributed on both sides of the second truss 6 and are respectively tied or welded to the second truss 6. The first truss 5 in specific embodiment 2 has a simple structure, lower cost, and is easier to install.
