Description

Composite heat-insulating structure for outer wall Technical Field The application relates to the technical field of wall heat preservation, in particular to an outer wall composite heat preservation structure. Background Along with the continuous improvement of the energy-saving requirement of the building, the external wall heat insulation system becomes an important component part of the modern building. Traditional external wall insulation structure adopts the mode of pasting or mechanical fixation to fix the heat preservation on the wall body basic unit generally, and wherein mechanical fixation relies on metal coupling mechanism (such as crab-bolt, fossil fragments etc.) to connect heat preservation and wall body. Although the stability of the heat insulation layer can be ensured by the structure, the metal connecting mechanism directly penetrates through the heat insulation layer or is in close contact with the heat insulation layer, so that a heat bridge is easy to form, heat transfer loss is caused, and the overall heat insulation effect is reduced. In addition, the metal pieces may also cause condensation, rust and structural durability problems. The Chinese patent with the bulletin number of CN211007104U in the prior art discloses a waterproof reinforcement type external wall insulation structure for a plate joint, which comprises a leveling layer, an insulation layer formed by a plurality of insulation plates and an adhesive layer. The structure is characterized in that a first reinforcing strip and a second reinforcing strip are respectively arranged between the transversely and vertically adjacent heat insulation boards, two ends of the reinforcing strips are inserted into the adjacent heat insulation boards to realize mechanical connection, and the second reinforcing strips are also fixed with an outer wall base layer through expansion bolts to provide additional anchoring. A typical concept in the prior art is to enhance the integrity and durability of insulation systems by strengthening the inter-panel connection and sealing process. However, despite improvements in structural reinforcement and waterproofing of the panel seams, there are inherent drawbacks in that, first, the reinforcement strips (typically aluminum strips) and expansion bolts employed are both of a high thermal conductivity metal material and form a direct, large area, plug-in or face contact with the insulation panels, resulting in significant thermal and acoustic bridging, severely impairing the overall insulation and sound insulation properties of the wall. Secondly, this structure does not set up effective heat-insulating or sound insulation interval between coupling mechanism and heat preservation, and heat and sound are very easy to conduct through continuous metal path. Disclosure of Invention The application provides an outer wall composite heat insulation structure which at least partially solves the technical problems. In a first aspect, the present application provides an external wall composite insulation structure, which adopts the following technical scheme: The utility model provides an outer wall composite insulation structure, includes heat preservation, coupling mechanism and wall body basic unit, coupling mechanism with connect through discontinuous contact portion between the heat preservation for at least one confined or semi-confined air cavity is formed between coupling mechanism and the heat preservation and/or inside the heat preservation, be provided with at least one wall in the air cavity, be used for splitting and support the air cavity. By adopting the technical scheme, the connecting mechanism and the heat preservation layer are assembled, and at least one closed or semi-closed cavity is formed at the interface of the connecting mechanism and the heat preservation layer or in the composite structure of the heat preservation layer. Firstly, the non-continuous contact part directly reduces the physical contact area between the connecting mechanism and the heat insulation layer, weakens the path of heat conduction and sound vibration conduction from the source, and lays a structural foundation for reducing the heat bridge and sound bridge effect. The formed air cavity has low heat conductivity, can effectively block heat flow, has the effects of heat insulation and sound insulation, and the partition in the air cavity has the effects of supporting the air cavity structure and preventing the air cavity structure from collapsing in the compression or installation process, so that the stability of the whole structure is enhanced. The problems of serious heat transfer and sound transmission caused by large-area contact of the connecting component and the heat insulation layer and unstable and easy failure of a simple cavity structure in the prior art are solved. Optionally, the partition is provided with a plurality of air holes. By adopting the technical scheme, on the formed air cavity structure w
