Description

Technical Field

[0001] This invention relates to the field of thermal insulation building technology, and in particular to an external wall insulation structure. Background Technology

[0002] Currently, existing buildings typically improve insulation by increasing wall thickness, which increases construction time and cost. Therefore, adding an insulation layer to the walls can further enhance insulation. However, various moisture sources during construction and natural indoor moisture can penetrate the insulation layer. This moisture condenses inside the insulation layer, reducing the thermal resistance of the insulation material and compromising its effectiveness. It can also lead to mold growth on the walls due to dampness. Furthermore, there is a risk of large-scale insulation layer detachment. Summary of the Invention

[0003] The purpose of this invention is to provide an external wall insulation structure that facilitates air intake and exhaust through the ventilation channel between the insulation layer and the wall body.

[0004] The objective of this invention is achieved as follows.

[0005] An external wall insulation structure includes a prefabricated partition device fixed to the wall body. The prefabricated partition device is used to separate upper and lower insulation layers. The bottom of the prefabricated partition device is provided with a horizontally arranged air inlet and exhaust channel, which are separated. The top of the inner end of the air inlet is provided with a first connecting port, and the outer end of the air inlet is connected to the outside. The first connecting port is used to connect with the exhaust channel between the insulation layer above the prefabricated partition device and the wall body. The bottom of the inner end of the exhaust channel is provided with a second connecting port, which is used to connect with the exhaust channel between the insulation layer below the prefabricated partition device and the wall body.

[0006] The prefabricated partition device supports the weight of the insulation layer above it and facilitates air intake for the upper insulation layer's venting channel through the first connecting port, while simultaneously allowing water vapor to escape through the lower insulation layer's venting channel through the second connecting port. This creates an air layer connected to the outside environment, with the first connecting port of the lower prefabricated partition device, the second connecting port of the upper prefabricated partition device, and the venting channel of the insulation layer between them. The thermal pressure difference drives the natural expulsion of water vapor, preventing low-temperature condensation, reducing the thermal resistance of the insulation layer, and preventing condensate from seeping in and damaging the insulation structure. This process requires no additional energy consumption. The air layer also acts as a thermal insulation buffer, further improving overall insulation performance and structural durability. The prefabricated partition device reduces on-site processing time, thereby improving construction efficiency and shortening the construction period. The prefabricated partition device separates the upper and lower insulation layers, preventing large-area water vapor penetration within the insulation layer.

[0007] Furthermore, the prefabricated partition device has slots for interlocking and fixing the bottom of the insulation layer above it. The prefabricated partition device supports and fixes the insulation layer, ensuring natural exchange between the insulation layer and the outside environment during the building adaptation phase, preventing moisture retention, condensation, and the risk of cracking and falling off the insulation layer.

[0008] Furthermore, the prefabricated partition device includes a first bracket and a second bracket. The second bracket has the aforementioned slot, and the bottom of the slot has a first through hole. The first bracket includes a vertical part and a horizontal part. The inner end of the horizontal part is connected and fixed to the front of the vertical part near the bottom. The exhaust duct and the air inlet duct are arranged side by side in the horizontal part, separated by a partition. The horizontal part has a second through hole corresponding to the first through hole, which connects to the air inlet duct. The bottom of the horizontal part has a second connecting hole connecting to the inner end of the exhaust duct. The second bracket and the first bracket are fixed to the wall body by connectors. The first bracket and the second bracket are manufactured separately and then reassembled, reducing production costs.

[0009] Furthermore, the horizontal section is designed to slope downwards from the inside to the outside at least on the outer bottom surface of the exhaust duct and the intake duct. Both the exhaust duct and the intake duct have waterproof designs at their outer ends to prevent water from entering them.

[0010] Furthermore, the horizontal section is inclined downwards from the inside to the outside at least on the top surface of the outer end of the exhaust duct and the intake duct, and the inclination angle of the top surface of the outer end of the exhaust duct and the intake duct is the same as the inclination angle of the bottom surface of the outer end of the exhaust duct and the intake duct. This improves the waterproofing effect of the outer end of the exhaust duct and the intake duct.

[0011] Furthermore, the second bracket has a U-shaped cross-section and sits on the horizontal part. The first and second through holes are aligned vertically to form the first communication opening. The connecting component is an expansion bolt. The inner sidewall of the second bracket and the front of the vertical part abut against each other and are fixed to the wall body together by the expansion bolt. The second bracket and the first bracket are tightly connected and firmly installed.

[0012] Furthermore, the outer wall of the second bracket is inserted upwards into the limiting groove of the insulation layer to form the aforementioned interlocking joint. The second bracket prevents the insulation layer from falling off.

[0013] Furthermore, a partition cavity is provided between the exhaust duct and the intake duct, and an insulation layer is installed inside the partition cavity. The exhaust duct and the intake duct are not easily interfered with, ensuring that the water vapor accumulated in the insulation layer is discharged through natural exchange.

[0014] Furthermore, the outer ends of both the exhaust and intake ducts are angled downwards. Both the exhaust and intake ducts are waterproof. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See Figure 1-7 The first embodiment shown includes an external wall insulation structure, comprising a prefabricated partition device 1 fixed to the wall body 5. The prefabricated partition device 1 is used to separate the upper and lower insulation layers 6. The bottom of the prefabricated partition device 1 is provided with a horizontally arranged air inlet duct 24 and a steam exhaust duct 23, which are separated. The top of the inner end of the air inlet duct 24 is provided with a first connecting port 11, and the outer end of the air inlet duct 24 is connected to the outside. The first connecting port 11 is used to connect with the steam exhaust channel 7 between the insulation layer 6 above the prefabricated partition device 1 and the wall body 5. The bottom of the inner end of the steam exhaust duct 23 is provided with a second connecting port 12, which is used to connect with the steam exhaust channel 7 between the insulation layer 6 below the prefabricated partition device 1 and the wall body 5.

[0024] The prefabricated partition device 1 supports the weight of the insulation layer 6 above it and facilitates air intake for the exhaust channel 7 of the upper insulation layer 6 through the first connecting port 11, while simultaneously allowing water vapor to exit through the exhaust channel 7 of the lower insulation layer 6 through the second connecting port 12. Thus, the first connecting port 11 of the lower prefabricated partition device 1, the second connecting port 12 of the upper prefabricated partition device 1, and the exhaust channel 7 of the insulation layer 6 between them form an air layer connected to the outside. The thermal pressure difference drives the natural discharge of water vapor, preventing low-temperature condensation and reducing the thermal resistance of the insulation layer 6, preventing condensate from seeping in and damaging the insulation layer 6's structure, and eliminating the need for additional energy consumption. The air layer also serves as a thermal insulation buffer, further improving overall insulation performance and structural durability. The prefabricated partition device 1 reduces on-site processing time, thereby improving construction efficiency and shortening the construction period. The prefabricated partition device 1 separates the upper and lower parts of the insulation layer 6, preventing large-area water vapor penetration within the insulation layer 6.

[0025] See Figure 2 As shown, in one specific implementation, the prefabricated partition device 1 is provided with a slot 31, which is used for interlocking and fixing the bottom of the insulation layer 6 on the prefabricated partition device 1. The prefabricated partition device 1 supports and fixes the insulation layer 6, and during the building adaptation stage, it can ensure that the insulation layer 6 can naturally exchange with the outside environment to avoid water vapor retention, prevent condensation (freezing in extremely cold regions), and avoid the risk of the insulation layer 6 cracking and falling off.

[0026] See Figure 2-6 As shown, in one specific embodiment, the prefabricated partition device 1 includes a first bracket 2 and a second bracket 3. The second bracket 3 has the slot 31, and the bottom of the slot 31 has a first through hole 32. The first bracket 2 includes a vertical part 21 and a horizontal part 22. The inner end of the horizontal part 22 is connected and fixed to the front of the vertical part 21 near the bottom. The exhaust duct 23 and the air inlet duct 24 are arranged side by side in the horizontal part 22, separated by a partition. The horizontal part 22 has a second through hole 26 corresponding to the first through hole 32, which connects to the air inlet duct 24. The bottom of the horizontal part 22 has a second connecting hole that connects to the inner end of the exhaust duct 23. The second bracket 3 and the first bracket 2 are fixed to the wall body 5 by a connector 4. The first bracket 2 and the second bracket 3 are manufactured separately and then reassembled, reducing production costs.

[0027] See Figure 2-6 As shown, in one specific embodiment, the horizontal portion 22 is inclined downwards from the inside to the outside at least corresponding to the outer bottom surface of the exhaust duct 23 and the intake duct 24. The outer ends of the exhaust duct 23 and the intake duct 24 are both designed to be waterproof to prevent water from entering the exhaust duct 23 and the intake duct 24.

[0028] See Figure 2-6As shown, in one specific embodiment, the horizontal portion 22 is inclined downwards from the inside to the outside at least corresponding to the top surface of the outer end of the exhaust duct 23 and the intake duct 24. The inclination angle of the top surface of the outer end of the exhaust duct 23 and the intake duct 24 is the same as the inclination angle of the bottom surface of the outer end of the exhaust duct 23 and the intake duct 24. The waterproof effect of the outer end of the exhaust duct 23 and the intake duct 24 is improved.

[0029] See Figure 2 , Figure 5-7 As shown, in one specific embodiment, the second bracket 3 has a U-shaped cross-section and sits on the horizontal part 22. The first through hole 32 and the second through hole 26 are aligned vertically to form the first connecting opening 11. The connecting member 4 is an expansion bolt. The inner sidewall of the second bracket 3 and the front of the vertical part 21 abut against each other and are fixed to the wall body 5 together by the expansion bolt. The second bracket 3 and the first bracket 2 are tightly connected and firmly installed.

[0030] See Figure 1 As shown, in one specific embodiment, the outer side wall of the second bracket 3 is inserted upward into the limiting groove 61 of the insulation layer 6 to form the concave-convex insertion. The second bracket 3 prevents the insulation layer from falling off.

[0031] See Figure 4 and Figure 7 As shown, in one specific implementation, a partition cavity 25 is provided between the exhaust duct 23 and the intake duct 24, and a thermal insulation partition layer 27 is provided inside the partition cavity 25. The exhaust duct 23 and the intake duct 24 are not easily interfered with, ensuring that the water vapor accumulated in the thermal insulation layer 6 is discharged through natural exchange.

[0032] See Figure 5 and Figure 6 As shown, in one specific implementation, the outer ends of both the exhaust duct 23 and the intake duct 24 are inclined downwards. The exhaust duct 23 and the intake duct 24 are waterproof.
