[0038] See also Figure 1~Figure 5, this embodiment provides an existing building insulation renewal system based on near-zero energy consumption, including an existing wall 1 and a post-renewal insulation wall 2; wherein the post-renewal insulation wall 2 is a renewal structure of the existing wall 1, and is intended to improve the structural strength and insulation function of the existing wall 1. Specifically, the existing wall 1 is formed on an existing building, and the existing wall 1 is defined as a wall that needs insulation renewal; the post-renewal insulation wall 2 includes a wave mesh frame 22 and an insulation layer, and the wave mesh frame 22 can be assembled and fixed to the existing wall 1, and the insulation layer is attached to the wave mesh frame 22. The wave mesh frame 22 and the insulation layer in the post-renewal insulation wall 2 are attached to the existing wall 1 after being integrally formed in the factory; or, after the wave mesh frame 22 is fixed to the existing wall 1, the insulation layer is attached to the wave mesh frame 22.

[0039] In the implementation, "existing buildings" are interpreted as: buildings that are above ground and whose main structures are no longer to be built and put into use. This embodiment has a wide range of applications and can be used as an urban renewal project for existing buildings. "Existing walls" are existing walls of existing buildings.

[0040] First, see Figure 1 and Figure 2 The later-updated thermal insulation wall 2 can be integrally formed in the factory, and then transported to the construction site and screwed into the existing wall 1 by self-tapping screws 23 for assembly and installation. Specifically, the thermal insulation layer of the later-updated thermal insulation wall 2 is thermal insulation concrete 24A, and the thermal insulation concrete 24A is attached to and formed on the wave mesh frame 22 to form the later-updated thermal insulation wall 2 as a whole.

[0041] Furthermore, the precast concrete slab is formed by pressing on the formwork platform with the corrugated mesh skeleton 22 as the structural carrier, and the post-updated thermal insulation wall 2 can be formed. If the pipeline layout needs to be updated, the wiring pipeline can be buried during prefabrication. It should be noted that the thermal insulation concrete 24A is a common building material, which is a concrete material formed by adding a foaming agent to a slurry made of cement-based cementitious materials, aggregates, admixtures, additives and water. This embodiment is not limited here, and it can be selected in time according to the progress of existing technology or the expected development of materials science.

[0042] After the later-updated thermal insulation wall 2 is formed, holes or grooves can be punched or slotted to plant the rebars 3. The positions of the rebars 3 are arranged according to the height direction of the later-updated thermal insulation wall 2. The rebars 3 extend to the ends of the later-updated thermal insulation wall 2 and are planted in the main structure of the building. Specifically, the main structure of the building is generally implemented as a structural beam of an existing building.

[0043] See also Figure 3 and Figure 4 As another implementation of this embodiment, the later updated thermal insulation wall 2 can also be formed as a prefabricated structure in an integrated manner in a factory and constructed and formed on site.

[0044] Specifically, in the present embodiment, the insulation layer includes an insulation board 21 and an insulation molding material 24, the wave mesh skeleton 22 is installed on one side of the insulation board 21, the wave mesh skeleton 22 and the insulation board 21 are fixed to the existing wall 1, the wave mesh skeleton 22 is located on the side of the insulation board 21 away from the existing wall 1, and the insulation molding material 24 is spray-molded on the wave mesh skeleton 22. The spraying of the insulation molding material 24 forms a protective layer of 0.8~1.2cm to prevent the structure of the steel bars and the wave mesh skeleton 22 from being exposed. Preferably, the insulation molding material 24 is an insulation paste, insulation mortar or foam insulation material. When using foam insulation material, a template can be supported on one side of the wave mesh skeleton 22, and the foam insulation material can be filled between the insulation board 21 and the template, and the template can be removed after molding.

[0045] The insulation board 21 is made of organic polymer material, preferably XPS material, which has certain structural strength and insulation function. In addition, shallow grooves can be opened on the insulation board 21 for wiring, which is convenient for the layout of pipelines (water pipes, wires and other water and electricity structure wiring) of the wall.

[0046] For further information, see Figure 7 The insulation board 21 can be a vacuum insulation panel for building (internationally referred to as VIP panel, vacuum insulation panels for building-ings). Figure 7 As can be seen from the structure (a), the insulation board 21 can be spliced ​​by multiple vacuum insulation boards for construction at the stepped opening, where the stepped opening is a dense structure, which can be used as a nailing point for self-tapping screws 23 to be nailed into the existing wall 1 for assembly and installation; or Figure 7 As can be seen from the structure (b), the insulation board skeleton 210 is formed of foam material, and the building vacuum insulation panel is embedded in the skeleton 210 to form the insulation board as a whole.

[0047] The prefabricated structure is a combination of an insulation board 21 and a wave mesh frame 22, wherein the wave trough position of the wave mesh frame 22 is fixed to the insulation board 21 by a fixing member. Figure 6 The fixing piece is a U-shaped buckle 25, the insertion part of the U-shaped buckle 25 is a barb structure, and the U-shaped buckle 25 fixes the corrugated mesh frame 22 to the insulation board 21 through the mesh of the corrugated mesh frame 22. The number of U-shaped buckles 25 is not limited, mainly to achieve stable assembly and fixation of the two. Similarly, the prefabricated structure is also fixed by nailing the self-tapping screws 23 into the existing wall 1.

[0048] Similarly, holes or grooves can be punched in the insulation molding material 24 layer to plant the reinforcement 3, and the position of the reinforcement 3 is arranged according to the height direction of the later updated insulation wall 2, and the reinforcement 3 extends to the end of the later updated insulation wall 2 and is planted in the main structure of the building. Specifically, the main structure of the building is generally implemented as a structural beam of an existing building.

[0049] See also Figure 5 When the later-updated thermal insulation wall 2 of this embodiment is installed on the outer wall of the existing wall 1, this embodiment further includes a mounting support 5, which is installed on the main structure of the building, and the anchor bar 3 is fixed to the mounting support 5. The mounting support 5 can be a mounting bracket, which is intended to provide an installation fulcrum for fixing the anchor bar 3, thereby assisting the stability of the later-updated thermal insulation wall 2 when used as an outer wall.

[0050] It should be noted that after the later-updated thermal insulation wall 2 is formed, plastering is required to form a plastering layer 4, and the plastering layer 4 is coated on the later-updated thermal insulation wall 2 to form a neater appearance.

[0051] Beneficial effects of this embodiment:

[0052] This solution is implemented on the existing wall 1 to update the insulation wall 2; specifically, the wave mesh frame 22 and the insulation layer are prefabricated or installed on site, which greatly improves the assembly speed and efficiency; and the wave mesh frame 22 plays a role in structural reinforcement, and the insulation layer plays a role in insulation update; so that the existing buildings can meet the needs of urban renewal infrastructure and better meet the needs of life.

[0053] The crests and troughs of the wave mesh skeleton 22 form a cavity area, which is convenient for pipeline layout and line reconstruction in old communities. There is no need to perform construction such as grooving on the structure of the existing wall 1, which can save labor and reduce dust pollution.

[0054] Through the specially made U-shaped buckle 25, which includes a barbed structure, the insulation board 21 and the corrugated mesh frame 22 can be easily assembled, and the construction is convenient, simple and convenient.
