The non-removable insulation template 5 is erected and connected to the outer side of the frame beams and columns 1. The connecting components 3 include metal connectors and an insulation material layer. The insulation material layer covers the outer surface of the metal connectors, and both the metal connectors and the insulation material layer penetrate the non-removable insulation template 5 from its outer side, thus connecting the connecting components 3 to the non-removable insulation template 5 and the frame beams and columns 1. The frame beams and columns 1 include frame steel reinforcement and concrete. The non-removable insulation template 5 is erected on the outer side of the frame steel reinforcement. The connecting components 3 penetrate the non-removable insulation template 5 and protrude from its inner side. Concrete is then poured up to the frame steel reinforcement, forming the frame beams and columns 1 between the frame steel reinforcement and the concrete, thus connecting the frame beams and columns 1, the non-removable insulation template 5, and the connecting components 3 together. The connecting component 3 penetrates through the non-removable insulation template 5 and connects to the beams and columns of the frame structure, thereby improving the connection's firmness, effectively preventing falls, and greatly enhancing the safety and stability of the energy-saving wall structure of the frame structure. Furthermore, the metal connector is made of metal, further ensuring a stable and reliable connection; the outer surface of the metal connector is covered with an insulation material layer, which effectively strengthens the thermal insulation effect of the energy-saving wall structure of the frame structure, further overcoming thermal bridging.

[0051] The prefabricated external wall panel 2 is installed on the outer side of the frame structure beams and columns 1 using an external mounting method. The prefabricated external wall panel 2 includes an insulation layer 21, which is made of fire-resistant material with a Class A fire rating. The corner joint component 4 includes a corner joint 41, a wall panel mounting component 42, and a connector 43. The wall panel mounting component 42 is connected to the insulation layer 21. One end of the corner joint 41 is connected to the frame structure beams and columns 1, and the connector 43 connects the other end of the corner joint 41 to the wall panel mounting component 42. During on-site construction, the corner joint 41 is connected to the frame structure beams and columns 1, and the corner joint 41 is connected to the wall panel mounting component 42 via the connector 43. This allows the prefabricated external wall panel 2 to be directly installed on the outer side of the frame structure beams and columns 1 via several corner joint components 4, thus achieving external mounting and fixing of the prefabricated external wall panel 2. Installation and disassembly are very convenient. The prefabricated exterior wall panel 2 is made of insulation material with a fire rating of Class A through the insulation layer 21, which effectively plays a fire prevention role and eliminates fire hazards.

[0052] In this embodiment, the non-removable insulation template 5 is connected to the outer side of the frame structure beams and columns 1, and the prefabricated external wall panel 2 is installed on the outer side of the frame structure beams and columns 1 using an external hanging method. The outer side of the non-removable insulation template 5 is flush with the outer side of the insulation layer 21. After the prefabricated external wall panel 2 is externally connected to the outer side of the frame structure beams and columns 1, masonry materials are installed on the inner side of the prefabricated external wall panel 2.

[0053] In this embodiment, the wall panel mounting component 42 is a nut sleeve with a cavity protruding from the inner side of the prefabricated external wall panel 2. The corner connector 41 has a connecting hole, and the connector 43 passes through the connecting hole and connects to the cavity. During the processing of the prefabricated external wall panel 2, the nut sleeve is placed in the raw material composition of the insulation layer 21 within the mold, so that the nut sleeve is pre-embedded in the insulation layer 21. During on-site construction, the connector 43 passes through the connecting hole on the corner connector 41 and connects to the cavity, thereby realizing the external fixing of the prefabricated external wall panel 2. Installation and disassembly are very convenient, construction efficiency is high, and the structure is simple and easy to process and manufacture.

[0054] Of course, in other embodiments, one end of the wall panel mounting member 42 abuts against the outer surface of the insulation layer 21, and the other end of the wall panel mounting member 42 passes through the insulation layer 21 and is connected to the connector 43. The wall panel mounting member 42 can be an anchor, with the anchor plate abutting against the outer surface of the insulation layer 21 and the anchor rod passing through the insulation layer 21 and connected to the connector 43.

[0055] In this embodiment, the corner connector 41 includes a horizontal plate 411, a vertical plate 412, and multiple snap-fit ​​parts 413. The horizontal plate 411 and the vertical plate 412 are respectively attached to the inner surfaces of the frame structure beams and columns 1 and the prefabricated external wall panel 2 and are connected to each other. The multiple snap-fit ​​parts 413 are all connected to the horizontal plate 411 and connected to the frame structure beams and columns 1. The connector 43 is connected to the vertical plate 412. The corner connector 41, through the horizontal plate 411 and the vertical plate 412 respectively attached to the frame structure beams and columns 1 and the prefabricated external wall panel 2, makes the connection more stable and reliable. At the same time, the horizontal plate 411 is connected to the frame structure beams and columns 1 through the multiple snap-fit ​​parts 413, further strengthening the structural connection strength and greatly improving the safety and stability of the energy-saving wall structure of the frame structure. Among them, the horizontal plate 411 and the vertical plate 412 are L-shaped angle irons.

[0056] Several corner connectors 4 are respectively connected to the top and bottom of the prefabricated external wall panel 2. The prefabricated external wall panel 2 is fixedly installed and connected to the outside of the frame structure beams and columns 1 through several corner connectors 4, and the connection stability is high.

[0057] In this embodiment, the insulation layer 21 is a Class A fire-resistant insulation material composed of a single homogeneous material. The Class A fire-resistant insulation material effectively ensures the fire resistance and insulation performance of the energy-saving wall structure of the frame structure, thus eliminating the need for additional inorganic composite panels to enhance its strength and fire resistance.

[0058] The insulation layer 21 can be made of polyurethane insulation material or silicon graphene insulation material, which effectively ensures the insulation and fire resistance of the energy-saving wall structure of the frame structure and greatly improves the safety and stability of the energy-saving wall structure of the frame structure.

[0059] The prefabricated exterior wall panel 2 also includes a reinforcing mesh 22, which is embedded within the insulation layer 21 and / or subsequently placed on the surface of the insulation layer 21. During the processing of the prefabricated exterior wall panel 2, the reinforcing mesh 22 is placed on top of the raw material composition of the insulation layer 21 after the first layer of material is applied within the mold. Then, the raw material composition of the insulation layer 21 is applied a second time within the mold, so that the raw material composition of the insulation layer 21 completely wraps around the reinforcing mesh 22 after the second layer of material is applied, thus embedding the reinforcing mesh 22 within the insulation layer 21. Alternatively, the reinforcing mesh 22 can be placed on the surface of the insulation layer 21 after the insulation layer 21 has been processed. The reinforcing mesh 22 further strengthens the overall structural strength of the energy-saving wall structure of the frame structure, greatly improving the safety and stability of the energy-saving wall structure of the frame structure.

[0060] Among them, the wall panel mounting component 42 is connected to the reinforcing mesh 22, and the corner joint component 4 is embedded in the insulation layer 21 through the wall panel mounting component 42 and connected to the reinforcing mesh 22, which further strengthens the structural connection strength and greatly improves the safety and stability of the energy-saving wall structure of the frame structure.

[0061] The interior and / or surface of the non-removable thermal insulation formwork 5 have reinforcing mesh components 51. The reinforcing mesh components 51 can effectively strengthen the structural strength of the non-removable thermal insulation formwork 5, thereby improving the safety and stability of the energy-saving wall structure of the frame structure.

[0062] Among them, the connecting component 3 is connected to the reinforcing mesh component 51, which further strengthens the structural connection strength and greatly improves the safety and stability of the energy-saving wall structure of the frame structure.

[0063] In this embodiment, the metal connector includes an anchor plate 31 and an anchor rod 32. The anchor plate 31 abuts against the outer side of the non-removable insulation template 5. One end of the anchor rod 32 is connected to the anchor plate 31, and the other end of the anchor rod 32 passes through the non-removable insulation template 5 and connects to the frame structure beams and columns 1. An insulation material layer covers the outer surfaces of the anchor plate 31 and the anchor rod 32. The metal connector abuts against the outer side of the prefabricated external wall panel 2 through the anchor plate 31, and connects the prefabricated external wall panel 2 to the frame structure beams and columns 1 through the anchor rod 32. The overall structure is simple and very convenient to use.

[0064] The outer surface of the connecting component 3 has an outwardly protruding blocking structure 33. The outwardly protruding blocking structures 33 are located on the anchor rod 32 and there are multiple of them. The multiple blocking structures 33 are closely abutted against the non-removable thermal insulation template 5 and the frame structure beams and columns 1, which further strengthens the connection strength of the energy-saving wall structure of the frame structure, effectively prevents falling, and greatly improves the safety and stability of the energy-saving wall structure of the frame structure.

[0065] The energy-saving wall structure of the frame structure also includes a plastering layer, which is connected to the outer side of the insulation layer 21. The plastering layer provides enhanced protection, ensuring the good functionality of the energy-saving wall structure of the frame structure. The plastering layer comprises mortar and a mesh fabric. The mortar is connected to the side of the insulation layer 21 facing away from the frame structure beams and columns 1, and the mesh fabric is embedded within the mortar. The mesh arrangement within the mortar enhances the overall structural strength of the plastering layer, while the mortar provides leveling and protection. Preferably, the mortar is a polymer-modified crack-resistant mortar.

[0066] The energy-saving wall structure of the frame structure also includes a finishing layer, which can be connected to the outer surface of the insulation layer 21 or directly connected to the outer surface of the plaster layer. The finishing layer protects the wall, beautifies the building, and meets usage requirements. The material of the finishing layer can be paint, ceramic tile, stone, metal sheet, or UHPC. When the finishing layer is made of UHPC, a reinforcing mesh structure is added within it. This reinforcing mesh structure effectively strengthens the structural strength of the finishing layer, greatly improving the stability of the energy-saving wall structure of the frame structure.

In this Embodiment 2, the prefabricated external wall panel 2 also includes a connecting layer 23, which is connected to the inner side of the insulation layer 21. The prefabricated external wall panel 2 is connected to the outer side of the frame structure beams and columns 1, and the connecting layer 23 is located inside the frame structure beams and columns 1. The connecting layer 23 can further strengthen the connection strength between the prefabricated external wall panel 2 and the frame structure beams and columns 1, greatly improving the structural stability and firmness.

[0069] In this embodiment 2, the connecting layer 23 is made of cement-based material.
