Description

Outer wall heat preservation and outer wall heat preservation structure

Technical Field

The utility model relates to the technical field of buildings, in particular to an outer wall heat preservation layer and an outer wall heat preservation structure.

Background

In a high-rise residential building, the heat loss ratio of each part is: about 26.6% of the outer wall, about 34.4% of the outer window, about 4.6% of the roof, about 6.4% of the outer door, about 8.7% of the inner partition wall of the stairwell, about 2.6% of the ground, and about 16.7% of the air permeation heat consumption. At present, relevant regulations require that new buildings around the country must be subjected to heat preservation, and energy conservation transformation is required for existing buildings.

The external wall heat preservation refers to adding a material with lower heat conductivity coefficient on the external wall surface of a building as a heat preservation layer, so that the heat preservation or heat insulation performance of the building is improved. Common thermal insulation materials include polyethylene foam board, extruded polystyrene board, rock wool board, polyurethane foam board, inorganic thermal insulation slurry and the like.

The new 'energy-saving design standard of residential building' improves the energy-saving rate of residential building from 75% to 80%, and the heat transfer coefficient K of the outer wall (main section) is less than or equal to 0.23W/(m < 2 >. K), so that the common heat-insulating material is difficult to meet the standard requirement. Taking the heat transfer coefficient K of the outer wall (main section) as less than or equal to 0.23W/(m2.K) as an example, the thickness of each heat insulation material is as follows: polyethylene foam board 200mm thick, extruded sheet 150mm thick, rock wool board 200mm thick, polyurethane foam board 120mm thick, inorganic thermal insulation mortar 700 thick. The heat preservation is thicker than the structure, seriously invades usable floor area, and can't carry out effective connection fixed.

The Vacuum Insulation Panel (VIP) is the material with the best heat preservation performance at present, and mainly comprises a core material, a film material and a getter, wherein the heat conductivity coefficient can reach 0.004W/(m.K). However, the vacuum sealing package is extremely easy to be pierced and damaged by sharp objects in the construction and transportation processes, so that the plate in a negative pressure state strongly absorbs air, the plate is invalid, and the heat insulation performance cannot be ensured. Vacuum Insulated Panels (VIPs) cannot be cut and anchored and perforated making them difficult to attach to structures. The board size is single, can't satisfy the diversified demand of building facade, and board and veneer hardly fixed connection.

The multi-layer independent vacuum cavity structure heat insulation plate has stable performance, prolonged service life and convenient industrialized production.

The advantages of the multi-layer independent vacuum chamber construction insulation panel of this embodiment are now analyzed from the heat transfer principle: three ways of heat transfer are: heat convection, heat radiation, heat conduction. For thermal convection: the chambers of the multi-layer independent vacuum chamber structure heat insulation plate are in a vacuum state, the internal air is thin, and the thickness of the single-layer chamber is not more than 15mm, so that the heat insulation plate has no gas flow, and therefore, no heat convection is generated. For thermal radiation: the outer side of the heat-insulating plate with the multilayer independent vacuum cavity structure is plated with a metal film, so that the air tightness of the plate can be enhanced, the permeation resistance can be improved, and meanwhile, the heat radiation transmission can be effectively blocked by the metal plating layer. For heat conduction: in an absolute vacuum state, heat cannot be transferred through a heat conduction mode, and the heat conductivity coefficient lambda in the absolute vacuum state is 0. However, in the industrial production application of the product, the absolute vacuum state cannot be realized, the common vacuum degree is 0.1pa, and the heat conductivity is relatively low. Because the single vacuum chamber still has certain heat transfer performance, so this patent adopts the independent vacuum chamber structure of multilayer, and every layer of cavity all has very low heat conductivility, through the superimposed structure of multilayer vacuum chamber, reduces the heat conductivility multiple level of vacuum plate, further improves the holistic thermal insulation performance of panel. In order to ensure that the vacuum state of the plate is not easy to be damaged, the vacuum plate is not suitable to use two (or more) materials with larger heat shrinkage ratio difference, otherwise, the joint is in the repeated heat shrinkage process, so that the fatigue damage and ventilation are caused, and the vacuum performance is lost. Therefore, the material used in the patent is a single hard plastic material, and has the same thermal shrinkage performance through welding and sealing, so that the fatigue damage condition during repeated thermal shrinkage can not occur. As the inner cavity of the vacuum plate is in a negative pressure state and is in a natural environment, the atmospheric pressure acts on the surface of the vacuum plate, so that the surface of the plate is pressed and deformed inwards. The outer walls of the vacuum plate need to be increased in thickness or reduced in size to resist atmospheric pressure. So the single-cavity structure wastes materials and increases the cost, which is not beneficial to market popularization. The inside cross type supporting partition board that is provided with of multicavity structure mainboard of this embodiment can effectively resist atmospheric pressure, increases monolithic panel size, reduces panel concatenation limit quantity, improves thermal insulation performance. The material consumption is reduced, and the product cost is reduced. The multilayer independent cavity structure that this embodiment adopted, the vacuum in all cavities is the same, forms the atmospheric pressure balance in panel inside, makes the cavity division board can not take place to warp the laminating. The multi-layer independent vacuum cavity structure heat insulation board has the advantages that the related hanging piece connection structure is considered in the processing production, and the installation is simple in the external wall heat insulation application. The hard plastic has low raw material price, mature processing technology, wide application in the building industry and easy popularization.
