In the present invention, the outer layer panels and the inner layer panels are arranged in parallel, and a plurality of vacuum insulation square panels are arranged on the outer side of the inner layer panels. A plurality of transverse gaps and a plurality of longitudinal gaps are formed between the plurality of vacuum insulation square panels, and each transverse gap is connected to a plurality of longitudinal gaps to form a plurality of central intersection areas. The two sides of each first vacuum insulation strip panel are respectively in close contact with the ends of the two adjacent vacuum insulation square panels, and a plurality of second vacuum insulation strip panels are arranged in each longitudinal gap. The other side of each vacuum insulation square panel is in close contact with the inner side of the outer layer panel, and a plug is connected to each jack of the outer layer panel.

Description

Technical Field

[0001] The present invention specifically relates to a non-disassembly exterior wall formwork based on a vacuum insulation panel. Background Art

[0002] The thermal insulation and heat insulation effect of the exterior wall of buildings in severe cold and cold regions is better than that of the interior wall insulation. Since the exterior wall insulation board material is attached to the outside of the wall, it is helpful to eliminate or weaken the influence of the thermal bridge generated around the junction of the interior and exterior walls, the exterior wall ring beam, the structural column, the frame beam, and the junction of the top parapet and the roof panel. At the same time, the exterior wall insulation structure can effectively prevent the condensation of water vapor inside the wall and completely eliminate the condensation phenomenon. At present, the construction process of the building is that the exterior wall structure construction and the exterior insulation system construction are completed separately. The exterior insulation system requires secondary construction operations, lacking a compact and continuous structural form to simplify the insulation construction process and the difficulty of operation. The vacuum insulation board is a kind of high thermal insulation material, which is composed of a filling core material and a vacuum protective surface layer. It can effectively avoid heat transfer caused by air convection, so the thermal conductivity can be greatly reduced, which can reach 0.002-0.004w / mk, which is 1 / 10 of the thermal conductivity of traditional insulation materials. The reason why the high-quality thermal insulation performance of vacuum insulation boards has not been widely used in the use environment of external insulation is mainly because the integrity requirements of vacuum insulation boards are high, and they must be kept intact and without perforations. Once perforated or there are traumatic parts, the thermal insulation performance of the vacuum insulation board will be greatly reduced. The specific on-site installation, splicing and other assembly methods make it difficult to apply vacuum insulation boards to structural insulation construction, limiting the wide application of vacuum insulation boards in exterior wall insulation projects.

[0006] 1.

[0007] Second, the present invention plays a role of template support in the concrete pouring process, and there is no need to remove the formwork, and it can be directly used for external insulation construction, thereby improving the smoothness of the connection between pouring and external insulation and simplifying the construction process.

[0008] 3. The overall structural form of the present invention with both external insulation and internal moisture removal can effectively improve the bonding reliability of the external wall insulation system, and prevent the external insulation system from falling off due to adverse environmental factors after the building is put into use; at the same time, the external wall structure construction and the external insulation system construction are completed simultaneously, avoiding secondary construction of the external insulation system and implementing integrated structural insulation construction; at the same time, it realizes a reasonable replacement of the external formwork of the traditional building exterior wall, reducing the investment in formwork materials and the workload of later demolition construction.

[0009] Fourth, the edges of the overall structure of the present invention are equipped with elastic strips, which can not only realize the stable connection of multiple composite vacuum insulation panels without demolding, but also provide adjustment positions for the connection between the templates, which is beneficial to the flatness of the outer wall plane, thereby ensuring the neatness and consistency of the building facade.
