In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0035] Combine the following Figures 1 to 6 The invention describes a thermal insulation template, an exterior wall construction component and an exterior wall construction method.

[0036] See also Figures 1 to 3 As shown, the thermal insulation template 10 provided in the embodiment of the present invention includes: a template body 110 , a steel mesh 120 and a plurality of extended anchor bars 130 .

[0037] The steel mesh 120 is embedded in the formwork body 110, and a plurality of extended anchor bars 130 are arranged on the side of the formwork body 110 facing the exterior wall. One end of the extended anchor bar 130 is located in the formwork body 110 and connected to the steel mesh 120, and the other end of the extended anchor bar 130 extends out of the formwork body 110.

[0038] The insulation formwork 10 provided by the present invention embeds a steel mesh 120 in the formwork body 110 and connects a plurality of extended anchor bars 130 to the steel mesh 120. During construction, the insulation formwork 10 can be directly used as a formwork for pouring the exterior wall of the building. After the pouring is completed, the plurality of extended anchor bars 130 are anchored in the main structure of the exterior wall, which can greatly improve the connection stability between the insulation formwork 10 and the main structure of the exterior wall. In addition, the insulation formwork 10 provided by the present invention also simplifies the construction process of the exterior wall of the building. In the later decoration stage, the exterior wall plastering process before the installation of the insulation board is omitted, thereby reducing the construction cost of the project and shortening the construction period.

[0039] Specifically, the shape of the template body 110 can be a regular shape such as a rectangle, parallelogram, triangle, or other polygon, or an irregular shape with a certain geometric shape. Preferably, the template body 110 in this embodiment is a rectangular structure.

[0040] The steel mesh 120 is made of a plurality of steel bars arranged in a crisscross pattern. One end of the extension anchor bar 130 is connected to the steel mesh 120, and its connection position can be selected arbitrarily according to demand. For example, one end of the extension anchor bar 130 can be connected to the intersection of the steel bars arranged in a crisscross pattern.

[0041] When the insulation template 10 is manufactured, the steel mesh 120 with the external anchor bar 130 is fixed in the mold, and the mold is filled with insulation material and pressed. After the pressing is completed, one end of the external anchor bar 130 extends out of the template body 110 to be anchored in the main structure of the exterior wall during the subsequent exterior wall construction process, thereby improving the connection stability between the insulation template 10 and the main structure of the exterior wall. When pressing, reinforcing fibers 140 such as glass fibers or basalt fibers can also be added to the insulation material (see Figure 4 As shown), while increasing the elastic strength of the insulation template 10, the crack resistance can be further enhanced.

[0042] Preferably, in this embodiment, the thermal insulation material is perlite, which is produced from volcanic eruptions and has extremely strong aging and fire resistance. While improving the aging performance of the thermal insulation layer, it also further enhances the fire resistance of the exterior wall.

[0043] See also Figures 1 to 3 As shown, according to some embodiments of the present invention, the extended anchor bar 130 extends in a random direction facing the side of the exterior wall.

[0044] By configuring the external anchor bars 130 to extend in a random direction facing the side of the exterior wall, the connection stability between the thermal insulation template 10 and the exterior wall main structure can be further improved. Specifically, the multiple external anchor bars 130 extending in random directions can exert anchoring forces in various directions on the thermal insulation template 10, so that the thermal insulation template 10 can be stably connected to the exterior wall main structure when disturbed by external forces in various directions, thereby preventing the thermal insulation template 10 from being deformed or unstable due to excessive force in a single direction.

[0045] According to some preferred embodiments of the present invention, the angle between the extended anchor bar 130 and the template body 110 is 30° to 60°.

[0046] By configuring the angle between the extended anchor bar 130 and the formwork body 110 to be 30° to 60°, while ensuring that multiple extended anchor bars 130 can apply anchoring forces in all directions to the insulation formwork 10, the depth of the extended anchor bars 130 anchored in the main structure of the exterior wall can be ensured, and the contact area between the extended anchor bars 130 and the main structure can be increased, thereby improving the stability and safety of the overall structure.

[0047] It should be noted that the angle between the extension anchor bar 130 and the template body 110 is the angle between the axis of the extension anchor bar 130 and the surface of the template body 110 facing the outer wall. The angles between the extension anchor bars 130 and the template body 110 can be partially the same, and the orientations of some extension anchor bars 130 can also be the same.

[0048] See also Figures 1 to 3 As shown, according to some embodiments of the present invention, the steel mesh 120 has a plurality of side connection portions 121 , and each side connection portion 121 extends out of the template body 110 to be connected to a corresponding side connection portion 121 of the steel mesh 120 of an adjacent insulation template 10 .

[0049] By arranging a plurality of side connection parts 121 extending out of the formwork body 110 on the outer periphery of the steel mesh 120, during construction, it is possible to easily connect a plurality of insulation formworks 10 through the corresponding side connection parts 121, thereby improving the integrity of the building exterior wall. At the same time, since the insulation formwork 10 is anchored in the exterior wall main structure through a plurality of extension anchor bars 130, it has a strong stability. When a single insulation formwork 10 is affected by external factors and its extension anchor bars 130 fail, the surrounding insulation formworks 10 can fix it to prevent it from falling off.

[0050] As an example, when the template body 110 is rectangular, it has four side connection parts 121, and each side connection part 121 is respectively connected to the corresponding side connection part 121 of the adjacent template body 110. When the template body 110 is triangular, it has three side connection parts 121, and each side connection part 121 is respectively connected to the corresponding side connection part 121 of the adjacent template body 110.

[0051] Specifically, in this embodiment, the side connection part 121 includes a plurality of side connection ribs arranged at intervals. During construction, the corresponding side connection parts 121 of adjacent template bodies 110 can be manually connected through the side connection ribs, which has a simple structure and is easy to construct.

[0052] See also Figure 3 As shown, according to some embodiments of the present invention, a polymer film 150 is provided on the side of the template body 110 facing the exterior wall.

[0053] By providing a polymer adhesive film 150 on the side of the template body 110 facing the exterior wall, the connection stability between the thermal insulation template 10 and the main structure of the exterior wall can be further enhanced.

[0054] Specifically, the polymer film 150 may be a polyethylene (PE) film, a polypropylene (PP) film, a polyurethane (PU) film, etc. The polymer film 150 has excellent adhesion, waterproofness, weather resistance and chemical corrosion resistance, and can provide long-term stable protection and connection effects.

[0055] The exterior wall construction assembly provided by the present invention is described below. The exterior wall construction assembly described below and the thermal insulation template 10 described above can correspond to each other.

[0056] See also Figures 1 to 3 and Figure 5 As shown, the exterior wall construction assembly provided by an embodiment of the present invention includes a fixed frame 20 and a plurality of insulation templates 10 as described in any of the above embodiments, the insulation templates 10 are connected to the corresponding sides of adjacent insulation templates 10, and the plurality of insulation templates 10 are detachably connected to the fixed frame 20.

[0057] The exterior wall construction assembly provided by the present invention, due to the use of the above-mentioned insulation template 10, can greatly improve the connection stability between the insulation template 10 and the main structure of the exterior wall, and also simplify the construction process of the building exterior wall. In the later decoration and renovation stage, the exterior wall plastering process before the installation of the insulation board is omitted, thereby reducing the construction cost and construction period of the project.

[0058] Specifically, the fixed frame 20 is made of steel, and includes a frame 210 and main ribs 220 staggered on the frame 210, and the main ribs 220 are connected by threaded connectors 230. Each fixed frame 20 fixes a plurality of insulation templates 10. For example, each fixed frame 20 fixes four insulation templates 10 arranged in a rectangular shape.

[0059] The shape of the fixed frame 20 is adaptively set according to the shape of the insulation template 10. As an example, in this embodiment, the insulation template 10 is a rectangular structure, so the fixed frame 20 is also correspondingly set to a rectangular structure.

[0060] According to some embodiments of the present invention, the steel meshes 120 of a plurality of thermal insulation templates 10 are integrally arranged.

[0061] By integrally arranging the steel meshes 120 of a plurality of thermal insulation templates 10 , the plurality of thermal insulation templates 10 can be processed into a modular structure, thereby reducing the construction period and construction difficulty during on-site construction.

[0062] For example, four insulation templates 10 arranged in a rectangular array are one module, the steel meshes 120 of the four insulation templates 10 are arranged in one piece, and the template body 110 is arranged separately, so as to ensure the uniformity of the building exterior wall. During construction, four insulation templates 10 can be used as a group, eliminating the process of connecting the insulation templates 10 of each module in the same module on site.

[0063] The exterior wall construction method provided by the present invention is described below. The exterior wall construction components described below and the insulation formwork 10 and exterior wall construction components described above can be referenced to each other.

[0064] See also Figure 6 As shown, the exterior wall construction method provided by the embodiment of the present invention is implemented based on the insulation template 10 as described in any of the above embodiments or the exterior wall construction assembly as described in any of the above embodiments, and includes the following steps.

[0065] S1. Connect the corresponding sides of adjacent insulation formworks 10 to each other, and connect the extended anchor bars 130 to the steel bars of the main structure of the exterior wall.

[0066] S2. The thermal insulation template 10 is supported and fixed by the fixing frame 20.

[0067] S3. Concrete is poured on the side of the insulation formwork 10 facing the reinforcement of the outer wall main structure to form the outer wall main structure, so that the extended anchor bars 130 are anchored in the outer wall main structure, and the insulation formwork 10 and the outer wall main structure are integrated.

[0068] S4, removing the fixed frame 20.

[0069] The exterior wall construction method provided by the present invention, due to the use of the insulation template 10 and exterior wall construction components described above, can also improve the connection stability between the insulation template 10 and the exterior wall main structure, and also simplify the construction process of the building exterior wall. In the later decoration and renovation stage, the exterior wall plastering process before the installation of the insulation board is omitted, thereby reducing the construction cost and construction period of the project.

[0070] Specifically, in step S1, corresponding sides of adjacent insulation templates 10 can be connected to each other by metal wires (such as steel wires) so that each insulation template 10 forms a whole, and the extended anchor bars 130 are fixed to the steel bars of the external wall main structure by binding with metal wires to achieve a physical connection effect.

[0071] In step S2, after the insulation template 10 is pre-fixed, a fixing frame 20 is arranged on the outside of the insulation template 10 for reinforcement. During this process, the verticality of the fixing frame 20 needs to be adjusted to meet the subsequent construction requirements.

[0072] In step S3, after the concrete pouring is completed, the extension anchor bar 130 can be anchored in the main structure of the exterior wall to improve the connection stability between the insulation formwork 10 and the main structure of the exterior wall.

[0073] In step S4, the fixed frame 20 is removed after the strength of the main structure of the exterior wall formed by pouring concrete reaches a specified value.

[0074] According to some embodiments of the present invention, before step S2, the process further includes injecting glue to seal the gaps between adjacent insulation templates 10.

[0075] By injecting glue to seal the gaps between adjacent insulation templates 10, the sealing can be effectively improved to prevent air, moisture and dust from entering, thereby enhancing the insulation effect, reducing the thermal bridge effect, and maintaining stable thermal insulation performance of the insulation template 10.

[0076] Specifically, silicone structural sealant can be used. Silicone structural sealant has excellent high temperature resistance, low temperature resistance, UV resistance and oxidation resistance, and can maintain stable performance for a long time in harsh environments.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
