Technical Field

[0001] The utility model relates to the technical field of external wall insulation systems, in particular to a VICP composite insulation board thin-plastered external wall insulation system for ultra-low energy consumption buildings. Background Art

[0002] Ultra-low energy consumption buildings refer to buildings that adapt to climate characteristics and natural conditions, use enclosure structures with higher thermal insulation and airtightness performance, adopt high-efficiency fresh air heat recovery technology, minimize the building's heating and cooling needs, make full use of renewable energy, provide a comfortable indoor environment with less energy consumption, and meet the basic requirements of green buildings.

[0003] At present, ultra-low energy buildings are mainly public buildings and low-rise residential projects. There are few precedents for high-rise ultra-low energy residential projects, and there is no mature experience to refer to for their external insulation systems and construction processes. The external enclosure structure of ultra-low energy buildings should adopt a maintenance structure with higher insulation performance and greater thermal inertia. Common ultra-low energy building exterior wall insulation systems include rock wool insulation board plastering exterior wall insulation and graphite polystyrene board plastering exterior wall insulation, but they all inevitably have thermal bridge effects caused by anchor hangers, and thus cannot meet the requirements of high insulation and ultra-low energy consumption. There are also common problems such as fire resistance, reliability of structural connections, durability and wind resistance.

[0004] Therefore, it is necessary to explore new exterior wall insulation systems suitable for high-rise and ultra-low energy consumption buildings. Utility Model Content

[0006] The VICP composite insulation board thin-plaster exterior wall external insulation system for ultra-low energy consumption buildings comprises a waterproof leveling layer, a bonding layer, a double-layer VICP composite insulation board, a single-layer VICP composite insulation board and a protective layer. The waterproof leveling layer is bonded to the outer side of the outer wall of the base wall, the double-layer VICP composite insulation board is bonded to the outer side of the waterproof leveling layer through the bonding layer, a thermal break anchor bolt is installed between two adjacent double-layer VICP composite insulation boards of the base wall, the cross-section of the double-layer VICP composite insulation board is a stepped structure, the single-layer VICP composite insulation board is embedded in the step of two adjacent double-layer VICP composite insulation boards, and the single-layer VICP composite insulation board is bonded to the outer side of the thermal break anchor bolt through an adhesive, and the protective layer is bonded to the outer sides of the double-layer VICP composite insulation board and the single-layer VICP composite insulation board.

[0007] Preferably, the waterproof leveling layer adopts polymer cement waterproof mortar or ordinary waterproof mortar.

[0008] Preferably, in this embodiment, the protective layer consists of a plastering layer and a finishing layer, the plastering layer is consolidated on the outer sides of the double-layer VICP composite insulation board and the single-layer VICP composite insulation board, and the finishing layer is consolidated on the outer sides of the plastering layer.

[0009] Preferably, the plastering layer is made of plastering mortar, and a glass fiber mesh is embedded in the plastering mortar.

[0010] Preferably, the finishing layer is made of paint, finishing mortar or flexible tiles.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. The VICP composite insulation board developed by our company has excellent thermal insulation performance, superior fire resistance, and is green and environmentally friendly. It is widely used in building energy-saving projects. The VICP composite insulation board is used as an external wall insulation material through a thin plastering construction process.

[0013] 2. The utility model separates the anchor hangers by a double-layer VICP composite insulation board and a single-layer VICP composite insulation board. At the same time, thermal bridge breaking anchor bolts are used to install the insulation boards to avoid the thermal bridge effect caused by the anchor hangers, thereby meeting the requirements of high thermal insulation and ultra-low energy consumption.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 5 As shown, the ultra-low energy consumption building VICP composite insulation board thin plaster exterior wall external insulation system includes a waterproof leveling layer 11, a bonding layer 12, a double-layer VICP composite insulation board 13, a single-layer VICP composite insulation board 16 and a protective layer. The waterproof leveling layer 11 is fixed to the outer side of the outer wall of the base wall 10, and the double-layer VICP composite insulation board 13 is adhered to the outer side of the waterproof leveling layer 11 through the bonding layer 12. The base wall 10 is formed between two adjacent double-layer VICP composite insulation boards 13. A thermal bridge breaking anchor 14 is installed between the two adjacent double-layer VICP composite insulation boards 13, the cross-section of the double-layer VICP composite insulation board 13 is a stepped structure, the single-layer VICP composite insulation board 16 is inlaid in the step of two adjacent double-layer VICP composite insulation boards 13, and the single-layer VICP composite insulation board 16 is adhered to the outside of the thermal bridge breaking anchor 14 by an adhesive 15, and the protective layer is consolidated on the outside of the double-layer VICP composite insulation board 13 and the single-layer VICP composite insulation board 16.

[0024] In this embodiment, the waterproof leveling layer 11 is made of polymer cement waterproof mortar or ordinary waterproof mortar. The waterproof mortar has good weather resistance, durability, impermeability, compactness, extremely high adhesion and extremely strong waterproof and anti-corrosion effects.

[0025] In this embodiment, the protective layer is composed of a plastering layer 17 and a finishing layer 18. The plastering layer 17 is fixed to the outside of the double-layer VICP composite insulation board 13 and the single-layer VICP composite insulation board 16, and the finishing layer 18 is fixed to the outside of the plastering layer 17. The plastering layer is composed of plastering mortar, which is applied on the wall insulation layer to protect the insulation layer and play a role in crack prevention, waterproofing and impact resistance. The finishing layer is a decoration layer arranged outside the insulation layer.

[0026] In this embodiment, the plastering layer 17 is made of plastering mortar, and a glass fiber mesh is embedded in the plastering mortar. Pressing the glass fiber mesh into the mortar can effectively increase the tensile strength of the protective layer on the one hand, and on the other hand, because it can effectively disperse stress, it can disperse the wider cracks that may have been generated into many finer cracks, thereby forming its anti-cracking effect.

[0027] In this embodiment, the finishing layer 18 is made of paint, finishing mortar or flexible tiles.

[0028] Working principle of VICP composite insulation board thin plaster exterior wall insulation system for ultra-low energy consumption buildings:

[0029] After the double-layer VICP composite insulation board is installed to the outer side of the outer wall of the base wall 10 through the bonding layer 12 and the thermal bridge breaking anchor 14, the single-layer VICP composite insulation board 16 is installed to the outer side of the thermal bridge breaking anchor 14 through the adhesive 15. Since the thermal bridge breaking anchor 14 is separated from the single-layer VICP composite insulation board by the double-layer VICP composite insulation board, the thermal bridge effect caused by the anchor hanger is avoided, meeting the requirements of high thermal insulation and ultra-low energy consumption.

[0030] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
