Description
Technical Field
The invention belongs to the technical field of buildings, and particularly relates to an external wall heat-insulation decoration system in a building envelope structure and an installation method thereof.
Background
The aim of saving resources and energy and establishing a conservation-oriented society is to reduce energy consumption and low carbon emission, while the direct energy consumption of the building accounts for 46-50% of the energy consumption of the whole society, and nowadays, if the wall is not subjected to heat preservation treatment, the energy consumption accounts for 50% of the total energy consumption of the building. The heat preservation and heat insulation performance of the wall body is improved for the heat preservation of the outer wall of the building, the conduction loss of indoor heat energy is reduced, and the indoor heat stability is improved.
Exterior wall insulation and decoration systems have been widely used throughout the world, especially in europe, since a long time ago. The heat insulating materials in China are started late, and although great progress is made, the existing external wall heat insulating and decorating system still cannot meet the requirements of the current continuously improved green energy-saving building standard and ecological environment protection and social sustainable development.
Wherein, an important deficiency of the prior external wall heat-insulating decorative system is the ubiquitous problem of heat bridges. The heat bridge is a region with relatively dense heat flow, which is formed by the heat transfer coefficient of some parts being larger than that of the adjacent parts and the heat preservation performance being poor, under the action of the indoor and outdoor temperature difference, the heat preservation effect is weakened, and the heat loss is increased. Specifically, the existing exterior wall insulation decoration system mainly comprises three forms of an exterior wall thin plastering system, an exterior wall dry hanging and an insulation decoration integrated plate. The thin plastering system is characterized in that a heat insulation material is fixed on a wall in an anchor bolt combination mode, a heat insulation layer of the thin plastering system is connected with the wall through a metal anchoring piece, and an obvious heat bridge is formed. When the heat preservation layer is spliced by the heat preservation plates which are made of rock wool, extruded sheets, polyurethane and the like and are easy to cut and splice, a certain heat bridge exists at the splicing part, and wall cracks can be generated sometimes. The outer wall dry hanging and heat preservation decoration integrated plate needs hanging pieces, and a heat bridge at the joint of the outer wall dry hanging and heat preservation decoration integrated plate is more obvious. Therefore, the existing external wall heat-insulation decoration system in any form cannot avoid the problem of heat bridge.
The heat insulation board for splicing into the heat insulation layer mainly comprises a vacuum heat insulation board and a non-vacuum heat insulation board. Wherein the core material and the edge of the vacuum insulation board can not be broken, the anchoring nail can not be used for direct penetration and fixation, and the vacuum insulation board can not be damaged in the construction process, and can not achieve the qualified insulation effect when damaged and leaked air. When the vacuum insulation board is used in the existing external wall insulation decoration system, the vacuum insulation board is easy to damage and leak air during manufacturing and transportation. For example, in the construction and installation process of the vacuum insulation board in the thin plastering system, plastering tools and mortar need to be contacted, and puncture and air leakage can be easily caused. The problem of the existing external wall heat insulation decoration system also limits the application of the vacuum heat insulation board in external wall heat insulation, and is not beneficial to the deep development of the external wall heat insulation technology.
Another problem of the existing external wall heat insulation decoration system is that the installation process is complicated and not firm enough, and the condition that the heat insulation layer falls off exists. The heat-insulating layer is generally primarily fixed on the wall body, and the heat-insulating layer cannot be well pressed on the outer wall although the heat-insulating layer is reinforced by other treatment modes such as anchor bolts in the conventional subsequent process. The heat preservation effect is influenced after a long time, and the potential safety hazard is also caused.
In addition, the existing external wall heat insulation decoration system has low construction efficiency due to the characteristics of the system, and cannot meet the requirement of environmental protection in construction. Particularly, factors such as field mortar stirring and the like exist in a thin plastering system, and the construction environment pollution is serious.
From the foregoing, it is highly desirable to develop a new external wall insulation decoration system and related installation method. Simple structure can effectively avoid the heat bridge problem, and the effectual polluted environment problem in just can solving the construction that keeps warm can be firm install on the wall body, effectual environmental protection, durable, the security is good. The installation process has the advantages of simple steps, high construction efficiency and less material damage. The method also has profound significance for the development and popularization of energy-saving buildings in China.

When the insulation boards 2 are non-vacuum insulation boards, as in the case of the first embodiment, all the insulation boards 2 can be anchored on the wall 1 by a conventional method, wherein the insulation boards 2 are close to the joints 211 of all the insulation boards and basically have no gaps; when heated board 2 is vacuum insulation board, like the condition of embodiment two, lean on closely mutually the heated board 2 in the position that need not install skeleton 4 additional, these heated board splice department 211 do not leave the gap, and reserve fixed clearance width D at the fixed position P of skeleton 4, with simple bonding mode with heated board 2 temporary fixation on wall body 1 can. Then, a heat insulation connecting piece 43 penetrates through the framework 4, the framework 4 is fixedly connected with the wall body 1 by fastening the heat insulation connecting piece 43, and the heat insulation layer 2 in the middle of the framework is tightly pressed on the wall body 1. Bonding heat preservation strip X in advance on the one side of decorative board 3 towards heat preservation 2, then with decorative board 3 pressfitting to heat preservation 2 on, put into skeleton 4 with the outer hem of decorative board 3 in, just with knot strip 5 with fastener 53 with both fastening connection for skeleton 4, compress tightly decorative board 3 while heated board concatenation department 211 is sealed by heat preservation strip X. And finally, a waterproof sealant is applied to the sealant coating position S to complete the structural sealing and waterproofing. The sealant coating portion S in the first and second embodiments includes a joint of the horizontal metal buckle strip 51 and the vertical metal buckle strip 52 and a seam pressed by the horizontal metal buckle strip 51 and the vertical metal buckle strip 52 around the decorative plate 3; this is an example, and according to the concrete demand of building appearance design in the actual construction, can only have horizontal metal buckle strip 51 or only vertical metal buckle strip 52, and the decorative board 3 has some edges direct mutual concatenation department also to be sealant coating department S all around, also beats waterproof sealant and forms structural closure.
It can be understood from the above embodiments that the present invention achieves the intended effects. The above-mentioned embodiments are only for explaining the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, and the scope of the present invention should not be limited by the embodiments.
