[0038] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] Please also refer to Figures 1 to 2 The assembled energy-saving composite wall panels provided by the present invention are now described. The assembled energy-saving composite wall panels comprise special-shaped columns 1, steel beams 3, energy-saving composite exterior wall panels 2, and decorative interior wall panels 7. The steel beams 3 are welded to the special-shaped columns 1 to form a wall frame. The energy-saving composite exterior wall panels 2 are positioned outside the steel beams 3, their sides connected to the special-shaped columns 1 via first connectors 9, and their bottoms connected to the floor via second connectors 6. The decorative interior wall panels 7 are positioned inside the steel beams 3 and connected to the energy-saving composite exterior wall panels 2 via third connectors 5.

[0040] The assembled energy-saving composite wall panels provided by the present invention are first welded together by prefabricated special-shaped columns 1 and steel beams 3 to form a frame structure, which provides stable and reliable support for the connection of inner and outer wall panels, and can improve the seismic performance of the entire wall after assembly; the outer wall panels and steel beams 3, the outer wall panels and special-shaped columns 1, and the inner wall panels and outer wall panels are respectively connected together by pre-buried connecting parts, which improves the reliability of the connection between the prefabricated parts, thereby avoiding the problem of the prefabricated parts falling off after connection.

[0041] The assembled energy-saving composite wall panels provided in this embodiment are prefabricated with each connecting member separately prefabricated in advance and embedded in a preset position of each prefabricated member when each prefabricated member is prefabricated. When each prefabricated member is assembled, the corresponding connecting members can be directly connected together. The connecting members can effectively avoid the influence of installation errors caused by prefabricated components and can provide a stable connection. In conjunction with the frame-type support structure, the seismic requirements are met. All components are assembled and connected, and the assembly is simple and convenient, which can greatly improve construction efficiency and reduce construction costs.

[0042] Among them, the energy-saving composite exterior wall panel 2 is a foam sandwich lightweight aggregate concrete composite wall panel, which is mainly composed of concrete, polystyrene foam board (EPS) and wire mesh. The wire mesh and foam board are mechanically connected to form a wire mesh insulation board. After supporting the formwork, concrete is poured on both sides to form an integral wall panel, which is connected to other parts through connectors.

[0043] The decorative interior wall panels 7 can be made of European pine boards and are connected to the energy-saving composite exterior wall panels 2 via third connectors 5. The various connectors in this embodiment are assembled and connected by channel steel, T-shaped steel 42, U-shaped steel 53, angle steel, rectangular steel plates, screws, and steel bars. The use of different steel sections for assembly and connection makes the production simple and convenient, and the strength is high, all of which can provide a good fixing effect.

[0044] Among them, the steel beam 3 is made of I-steel and is welded to the connecting surface of the special-shaped column 1. The welding fixation is more firm, which improves the stability of the supporting frame and provides reliable support for each wall panel.

[0045] Each of the special-shaped columns 1 is formed by I-beams, T-beams 42, and angle steels, which are connected by bolts after being overlapped by flanges or flanges and webs, and webs and webs. Each of the special-shaped columns 1 has a connection surface for connecting to other components. The specific structural shape will be described in detail later. In the present invention, the various steel sections used in the special-shaped columns 1 can be of the same or different specifications. When combining, a minimum number of specifications is used as much as possible to facilitate assembly. The thickness of the steel sections of each specification is the same. The connection of the various steel sections adopts the method of overlapping flanges, overlapping flanges and webs, and overlapping webs to improve the reliability of the connection.

[0046] All prefabricated components were prefabricated in the factory and dry-connected at the construction site, facilitating rapid construction and ease of installation. For the foam-core lightweight aggregate concrete composite wall panels, lightweight materials such as polystyrene foam (EPS) are used as infill, significantly reducing the structure's deadweight while providing excellent thermal insulation, heat insulation, and sound insulation. A wire mesh frame is placed within the insulation panel, connecting it to the concrete slabs on either side, giving the panel greater rigidity and enabling it to withstand vertical loads and horizontal forces such as earthquakes and wind. Vertically adjacent wall panels are connected by tongue-and-groove connections on the insulation panel, effectively preventing defects such as water leaks, cold bridges, and thermal bridges at the panel joints.

[0047] In some embodiments, as Figures 1 to 4As shown, the energy-saving composite exterior wall panel 2 includes an L-shaped wall panel 21, a vertical upper wall panel 22 and a vertical lower wall panel 23. The L-shaped wall panel 21 is wrapped around the outside of the special-shaped column 1 and is connected to the special-shaped column 1 through a first connecting member 9; the vertical upper wall panel 22 is wrapped around the outside of the steel beam 3, and the vertical lower wall panel 23 is connected to the bottom of the vertical upper wall panel 22 through a fourth connecting member 8; the height of the vertical upper wall panel 22 and the vertical lower wall panel 23 after being connected is the same as the height of the L-shaped wall panel 21.

[0048] To accommodate different locations, each wall panel has different specifications. Wall panels are categorized based on their functionalities, with different specifications set accordingly. L-shaped wall panel 21 wraps around the L-shaped corner post and is welded to the L-shaped corner post via a first connector 9. The lower end of L-shaped wall panel 21 can also be connected to the floor slab or floor via a second connector 6 (e.g., angle steel). Vertical lower wall panel 23 serves as the overall framework of the house. Its upper end is connected to the steel beam 3 via a fifth connector 4, and its lower end is connected to the floor slab or floor via a second connector 6 (e.g., angle steel). Vertical upper wall panel 22 wraps around the steel beam 3 and is connected to the vertical lower wall panel 23 via a fourth connector 8.

[0049] The energy-saving composite exterior wall panel 2 of this embodiment is divided into multiple modules based on their location. Prefabrication of these modules based on the specific circumstances of each location reduces the difficulty of prefabrication and facilitates the transportation and on-site assembly of the prefabricated components. Furthermore, the modules are connected using connectors, effectively minimizing the impact of installation errors caused by prefabrication. The connection between these wall panel modules, as well as between the special-shaped columns 1 and the steel beams 3, further enhances the stability and reliability of the connection.

[0050] In some embodiments, as Figure 8 As shown, the first connector 9 includes a first steel plate 91 and a first anchoring bar 92 welded perpendicularly to the first steel plate 91. The first anchoring bar 92 is embedded in the concrete slab of the L-shaped wall panel 21, while the first steel plate 91 is exposed outside the concrete slab of the L-shaped wall panel 21. The first steel plate 91 is welded to the connection surface of the special-shaped column 1. The first connector 9 is prefabricated in advance and embedded in the concrete slab during the prefabrication of the L-shaped wall panel 21. During on-site assembly of the L-shaped wall panel 21 and the L-shaped corner column, the first steel plate 91 can be directly welded to the L-shaped corner column, improving on-site assembly efficiency and ensuring reliable weld fixation.

[0051] In some embodiments, as Figure 1 and Figure 4As shown, the thickness of the vertical lower wall panel 23 is greater than that of the vertical upper wall panel 22. Together, the vertical lower wall panel 23 and the vertical upper wall panel 22 form a step on the underside of the steel beam 3. The vertical lower wall panel 23 is connected to the underside of the steel beam 3 via the fifth connector 4. Specifically, since each wall panel has concrete slabs on both sides, the thickness of the vertical upper wall panel 22 can be increased by removing the inner concrete slab. The fifth connector 4 is connected to the lower flange of the steel beam 3, connecting it to the vertical lower wall panel 23.

[0052] The specific connection between the vertical lower wall panel 23 and the steel beam 3 is as follows: Figure 1 、 Figure 5 and Figure 9 As shown, the fifth connecting member 4 includes a fifth channel steel 41, a T-shaped steel 42 fixed in the fifth channel steel 41, and a fifth angle steel 43 connected to the T-shaped steel 42, wherein the flange of the fifth channel steel 41 is welded to the lower side of the steel beam 3, and the T-shaped steel 42 is fixed to the web of the fifth channel steel 41 by a fifth bolt 44. A fifth long strip hole is provided on the web of the fifth channel steel 41 along the length direction, which allows the T-shaped steel 42 to move left and right along the fifth channel steel 41, so that the fixed position of the T-shaped steel 42 can be adjusted at any time according to the preset fixed point; when the T-shaped steel 42 slides to the specified position along the fifth channel steel, it can be preliminarily connected with bolts. The fifth angle steel 43 is connected to the wing plate of the T-shaped steel 42 through the vertical adjusting bolt 45. The height of the fifth angle steel 43 can be adjusted by the vertical adjusting bolt 45, which can effectively eliminate errors and improve construction efficiency. A fifth reserved hole is provided on the fifth angle steel 43, and a prefabricated hole is also provided on the vertical lower wall panel. By adjusting the height of the vertical adjusting bolt 45, the height of the fifth reserved hole on the fifth angle steel 43 can be adjusted to ensure that the fifth reserved hole is concentric with the prefabricated hole on the vertical lower wall panel. Therefore, the position adjustment of the left and right directions and the up and down directions of the fifth connecting part can be achieved through the fifth long hole on the fifth channel steel and the vertical adjusting bolt 45, which is convenient for adjusting the concentricity of the fifth reserved hole and the prefabricated hole, and then the bolts can be used to connect them, which greatly improves the assembly convenience of related components, eliminates assembly errors, and improves the assembly quality and efficiency.

[0053] At the same time, the verticality and flatness of the wall can be measured with a ruler, and the positioning and verticality of the wall can be adjusted by loosening and tightening the bolts. There is no need to use tools such as wooden wedges and crowbars to correct the verticality and flatness of the wall. After the flatness and verticality meet the requirements, tighten the corresponding bolts to complete the fixation between the walls and between the wall and the frame.

[0054] The connecting parts connected by bolts in this embodiment all have the advantages of pre-installation, elimination of assembly errors, and improvement of assembly convenience and efficiency.

[0055] It should be noted that, in this article, since the structures of the connectors used in different positions are different, the "first" and "second" series are used for distinction. However, the names of the fifth channel steel 41 and the bolts in this article are only to correspond to the names of the connectors, and do not imply the number of bolts or channel steels.

[0056] In some embodiments, as Figure 4 and Figure 7 As shown, the fourth connecting member 8 includes a fourth steel plate 82, a fourth anchoring rib 81 vertically fixed to the fourth steel plate 82, and an embedded screw 83, wherein the fourth anchoring rib 81 is embedded in the lower end of the concrete slab of the vertical upper wall panel 22, the fourth steel plate 82 is exposed at the lower end of the vertical upper wall panel 22, the embedded screw 83 is embedded in the upper end of the concrete slab of the vertical lower wall panel 23, and a fourth through hole is provided on the fourth steel plate 82 for the embedded screw 83 to pass through. When the vertical upper wall panel 22 and the vertical lower wall panel 23 are assembled, the embedded screw 83 passes through the fourth through hole on the fourth steel plate 82 and is fastened together with a nut; wherein, a corresponding notch is provided on the concrete slab of the vertical upper wall panel 22 to avoid the embedded screw 83.

[0057] Optionally, the vertical lower wall panel 23 and the vertical upper wall panel 22 may be connected only by a tongue-and-groove connection.

[0058] In some embodiments, vertical upper wall panels 22 and vertical lower wall panels 23, as well as between adjacent vertical upper wall panels 22 and adjacent vertical lower wall panels 23, can be provided with interlocking tongue-and-groove structures (not shown in the tongue-and-groove structure diagram) on the insulation panels between each of the insulation panels, depending on design requirements. The tongue-and-groove structure connects two vertically adjacent wall panels, and concrete slabs are placed on both sides of the insulation panels to block the gaps where the tongue-and-groove meet, effectively preventing defects such as water leakage and cold bridges at the panel joints.

[0059] In some embodiments, as Figure 1 and Figure 6 As shown, the third connecting member 5 includes a third steel plate 55, a third channel steel 51 welded to both ends of the third steel plate 55, and a U-shaped steel 53 slidably connected to the third channel steel 51. The third channel steel 51 is provided with a third elongated hole, and the U-shaped steel 53 is fastened to the third channel steel 51 via a third bolt 54 passing through the third elongated hole. The third steel plate 55 is provided with a third reserved hole and is connected to the vertical lower wall panel 23 via a fourth bolt 56. The decorative interior wall panel 7 is connected to the U-shaped steel 53 via self-tapping screws 52. The third connecting member 5 forms a frame structure, which improves the stability of the connection between the decorative interior wall panel 7 and the energy-saving composite exterior wall panel 2.

[0060] The third reserved hole in the third steel plate 55 facilitates the connection between the third steel plate 55 and the vertical lower wall panel 23. The U-shaped steel 53 can slide back and forth along the third channel steel 51 to adjust the prefabricated components, eliminating dimensional errors. The two are connected and fixed by third bolts 54. The U-shaped steel 53 is provided with reserved bolt holes to facilitate the fastening of the decorative interior wall panel 7 to the third connecting member 5 using self-tapping screws 52.

[0061] By sliding the U-shaped steel 53 back and forth, pre-tighten it with bolts until the verticality and straightness of the entire wall surface meet the requirements, and then tighten the bolts. When the flatness of the entire wall surface does not meet the requirements, it can be adjusted at any time with the bolts.

[0062] In some embodiments, as Figure 1 and Figure 2 As shown, the special-shaped column 1 includes an L-shaped corner column a, a straight side column b, a T-shaped side column c and a cross-shaped center column d, wherein the L-shaped corner column is set at the corner of the composite wall panel and has two vertically connected connection surfaces; the straight side column is used for the left and right joints of the composite wall panel and has two parallel connection surfaces; the T-shaped side column is set at the intersection of three composite wall panels and has three connection surfaces; the cross-shaped center column is set at the intersection of four composite wall panels and has four connection surfaces.

[0063] The various shapes of the special-shaped columns 1 provided in this embodiment have different cross-sections to accommodate different locations. The special-shaped columns 1 are categorized based on their locations, resulting in different cross-sections. L-shaped corner columns are located at the corners of exterior walls, so two perpendicular connection surfaces are sufficient for connection to the steel beams 3. I-shaped side columns are used between exterior and interior walls, and two opposing connection surfaces are provided for connection to the steel beams 3. T-shaped side columns have three connection surfaces, allowing connection to the steel beams 3 from three sides. Finally, cross-shaped center columns have four connection surfaces, connecting to the steel beams 3 from all four sides.

[0064] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0065] Based on the same inventive concept, the embodiment of the present application also provides an assembly method based on the assembled energy-saving composite wall panel, such as Figure 1 As shown, the method includes:

[0066] Step 1: prefabricate the connecting parts and embed the connecting parts in the preset positions when prefabricating the energy-saving composite exterior wall panels 2 and the decorative interior wall panels 7 according to the preset requirements;

[0070] Step 5: The lower end of the vertical lower wall panel 23 in the prefabricated energy-saving composite exterior wall panel 2 is fastened to the floor via the second connecting member 6, and the upper end thereof is connected to the steel beam 3 via the fifth connecting member 4;

[0071] Step 6: The vertical upper wall panel 22 of the prefabricated energy-saving composite exterior wall panel 2 is connected to the vertical lower wall panel 23 through the fourth connecting member 8;

[0072] Step 7: The vertical lower wall panels 23 and the vertical upper wall panels 22, the adjacent vertical upper wall panels 22, and the adjacent vertical lower wall panels 23 are engaged with each other through tongue and groove;

[0073] Step eight, the decorative inner wall panel 7 is connected to the energy-saving composite outer wall panel 2 through the third connecting member 5;

[0074] By sliding the U-shaped steel 53 of the third connecting member 5 back and forth, first use the third bolts 54 to pre-tighten until the verticality and flatness of the wall surface of the entire decorative inner wall panel meet the requirements, then tighten each third bolt 54, and then tighten the self-tapping screws 52. When the flatness of the entire wall surface does not meet the requirements, it can be adjusted at any time through the third bolts 54.
