Description

Technical Field

[0001] This utility model relates to the field of external wall insulation technology, and in particular to an external wall insulation structure with a ventilation cavity. Background Technology

[0002] In the field of building energy conservation, external wall insulation structures are a core component for reducing building energy consumption and improving indoor thermal comfort. They primarily work by installing a thermally insulating layer on the exterior of the building's walls to block the rapid transfer of heat between the interior and exterior, thereby reducing heat loss in winter and heat intrusion in summer. With technological advancements, external wall insulation structures with ventilation cavities have become increasingly common. These structures create ventilation cavities by reserving specific spaces between the insulation layers. The airflow within these cavities further optimizes thermal performance. Theoretically, the ventilation cavities can remove some heat through airflow, enhancing insulation performance in summer. Simultaneously, in winter, reduced airflow helps maintain the temperature within the cavities, further strengthening the insulation capacity in conjunction with the insulation layer. Therefore, this has become an important structural form for balancing the energy-saving needs of buildings in both winter and summer.

[0003] However, existing exterior wall insulation structures with ventilation cavities still have significant technical defects in practical applications, making it difficult to fully utilize the regulating function of the ventilation cavities. Most structures do not have flexibly controllable ventilation paths designed for the ventilation cavities, which are often in a semi-open or fixed open state: In summer, air circulation inside the cavity relies on natural wind pressure, lacking guiding pathways, and hot air cannot be quickly and directionally discharged, making it difficult to form an efficient "chimney effect," resulting in lower-than-expected thermal insulation efficiency; In winter, the ventilation cavities cannot be effectively sealed, and cold outdoor air easily enters the cavity and mixes with the preheated indoor air, accelerating heat loss and weakening the thermal insulation effect. Therefore, this application proposes an exterior wall insulation structure with ventilation cavities to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide an external wall insulation structure with a ventilation cavity, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An exterior wall insulation structure with ventilation cavities includes an exterior wall structure. An insulation structure is fixedly installed on the exterior wall surface of the exterior wall structure. The insulation structure includes an exterior insulation board and a decorative layer. The decorative layer is fixedly installed on the outer end of the exterior insulation board. Two ventilation slots are symmetrically formed at the upper and lower parts of the exterior insulation board and the decorative layer, penetrating both the exterior insulation board and the decorative layer. Two mounting brackets are symmetrically fixedly installed on the left and right sides of the lower ventilation slots at the outer end of the decorative layer. Each mounting bracket consists of a base plate, a bushing, and a mounting plate. The bushing is fixedly installed on the lower part of the outer end of the base plate. The mounting plate is fixedly installed on the upper part of the outer end of the base plate. The mounting plate is equipped with a fastener, which consists of a hand-tightening bolt and a U-shaped fixing bracket. The hand-tightening bolt is rotatably installed on the upper end of the U-shaped fixing bracket. A sealing door is rotatably installed on two bushings on the two mounting brackets. The sealing door consists of a sealing plate, a rubber sealing frame, a rotating shaft, and a fixing rod. The rubber sealing frame is fixedly installed on one end of the sealing plate. There are two rotating shafts, which are symmetrically fixedly installed on both ends of the sealing plate. There are also two fixing rods, which are symmetrically fixedly installed on both ends of the sealing plate.

[0006] Preferably, a roof beam is fixedly installed at the upper end of the exterior wall structure, and the exterior wall structure consists of a wall and a mortar leveling layer, with the mortar leveling layer fixedly installed at the outer end of the wall.

[0007] Preferably, the insulation structure is located below the roof beam. The insulation structure also includes an inner insulation board, an adhesive layer, crack-resistant mortar, and connecting frames. The adhesive layer is fixedly disposed at the inner end of the inner insulation board, and the crack-resistant mortar is fixedly disposed at the outer end of the inner insulation board. The adhesive layer is also fixedly disposed at the outer end of the mortar leveling layer. There are several connecting frames, all of which are fixedly disposed at the outer end of the crack-resistant mortar. The outer insulation board is fixedly disposed on several connecting frames. The space between the outer insulation board and the crack-resistant mortar is a ventilation cavity.

[0008] Preferably, a protective net is fixedly installed inside the ventilation slot, the base plate on the mounting frame is fixedly installed on the outer end of the decorative layer, and the mounting plate has threaded holes.

[0009] Preferably, the hand-tightening bolt on the fastener is installed in the threaded hole, and the U-shaped fixing bracket is located below the mounting plate.

[0010] Preferably, the rotating shaft on the sealing door is rotatably mounted inside the bushing.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By installing two ventilation slots on the upper and lower sides of the outer insulation panel and decorative layer of the insulation structure, which communicate with the ventilation cavity inside the insulation structure, and installing mounting brackets on both sides of the lower ventilation slot, and installing openable and closable sealing doors on the two mounting brackets, the sealing doors can be opened in summer to allow cold air from outside to enter the ventilation cavity through the lower ventilation slot, forming convection with the hot air inside the cavity. The hot air then exits from the upper ventilation slot, quickly removing heat from the cavity through the efficient "chimney effect," thus forming a ventilation path and significantly improving the heat insulation efficiency in summer. In winter, the sealing doors are closed, and the rubber sealing frame on the sealing doors... The lower ventilation slot can be tightly sealed to close the ventilation passage, reducing the mixing of cold outdoor air entering the ventilation cavity with preheated indoor air, effectively reducing heat loss, enhancing the insulation effect in winter, achieving a flexible balance between winter and summer energy-saving needs, and solving the problem of poor adjustment capacity of existing ventilation cavities; by setting fixing parts on the mounting frame, when the sealed door is opened in summer, it can be firmly fixed to prevent the sealed door from shaking or closing at will under the action of natural wind and other external forces, ensuring that the ventilation cavity maintains a high-efficiency ventilation state and ensuring the stability of the heat insulation effect in summer.

The sealing door 26 consists of a sealing plate 22, a rubber sealing frame 23, a rotating shaft 24, and fixing rods 25. The rubber sealing frame 23 is fixedly installed on one end of the sealing plate 22. There are two rotating shafts 24 symmetrically fixedly installed on both ends of the sealing plate 22. There are also two fixing rods 25 symmetrically fixedly installed on the sealing plate 22. At both ends of the panel 22, two ventilation slots 14 are provided on the upper and lower sides of the outer insulation panel 12 and decorative layer 13 of the insulation structure 3, which are connected to the ventilation cavity inside the insulation structure 3. Mounting brackets 4 are provided on both sides of the lower ventilation slot 14, and openable and closable sealing doors 26 are provided on the two mounting brackets 4. In summer, the sealing doors 26 can be opened to allow cold air from the outside to enter the ventilation cavity through the lower ventilation slot 14, forming convection with the hot air inside the cavity. The hot air is then discharged from the upper ventilation slot 14, quickly removing the heat inside the cavity with the help of the efficient "chimney effect", thus forming a ventilation passage and significantly improving the heat insulation efficiency in summer. In winter, the sealing doors 26 are closed, in conjunction with the sealing door 2 The rubber sealing frame 23 on the 6 can tightly seal the lower ventilation slot 14, thereby closing the ventilation passage, reducing the mixing of outdoor cold air entering the ventilation cavity with the preheated air coming out of the room, effectively reducing heat loss, enhancing the winter insulation effect, achieving a flexible balance between winter and summer energy-saving needs, and solving the problem of poor adjustment capacity of the existing structure ventilation cavity; by setting the fixing part 5 on the mounting bracket 4, when the sealing door 26 is opened in summer, the sealed door 26 can be firmly fixed after opening, preventing the sealed door 26 from shaking or closing at will under the action of natural wind and other external forces, ensuring that the ventilation cavity continues to maintain a highly efficient ventilation state, and ensuring the stability of the summer heat insulation effect.

[0016] Specifically, a beam 2 is fixedly installed at the upper end of the exterior wall structure 1. The exterior wall structure 1 consists of a wall 6 and a mortar leveling layer 7. The mortar leveling layer 7 is fixedly installed at the outer end of the wall 6. The insulation structure 3 is located below the beam 2. The insulation structure 3 also includes an inner insulation board 8, an adhesive layer 9, crack-resistant mortar 10, and connecting frames 11. The adhesive layer 9 is fixedly installed at the inner end of the inner insulation board 8, and the crack-resistant mortar 10 is fixedly installed at the outer end of the inner insulation board 8. The adhesive layer 9 is also fixedly installed at the outer end of the mortar leveling layer 7. There are several connecting frames 11, all of which are fixedly installed at the outer end of the crack-resistant mortar 10. The external insulation board 12 is fixedly installed on several connecting brackets 11. The space between the external insulation board 12 and the crack-resistant adhesive 10 is a ventilation cavity. A protective net 15 is fixedly installed in the ventilation slot 14. The base plate 16 on the mounting bracket 4 is fixedly installed on the outer end of the decorative layer 13. The mounting plate 18 has threaded holes 19. The hand-tightening bolts 20 on the fastener 5 are installed in the threaded holes 19. The U-shaped fixing bracket 21 is located below the mounting plate 18. The rotating shaft 24 on the sealing door 26 is rotatably installed in the bushing 17. When using this external wall insulation structure with ventilation cavity, in winter, it is necessary to operate the installation first. The fixing piece 5 on the mounting bracket 4, by rotating the hand-tightening bolt 20, moves the U-shaped fixing bracket 21 upward and disengages it from the fixing rod 25 of the sealing door 26. Then, the sealing door 26 is rotated around the rotation axis 24 to close the lower ventilation groove 14. At this time, the rubber sealing frame 23 will fit against the outer end of the decorative layer 13 and cover the lower ventilation groove 14, thereby sealing the lower ventilation groove 14, reducing the entry of cold outdoor air into the ventilation cavity, reducing the loss of heat in the ventilation cavity, and ensuring the heat preservation effect in winter. In summer, the sealing door 26 is first rotated upward around the rotation axis 24 to open the sealing door 26. Open the door 26 so that the sealing plate 22 of the sealing door 26 fits against the outer end of the decorative layer 13. Finally, rotate the hand-tightening bolt 20 so that the hand-tightening bolt 20 moves downward in the threaded hole 19. Finally, let the U-shaped fixing bracket 21 move downward and clamp onto the fixing rod 25, thereby fixing the upward-opening sealing door 26. At this time, the cold air outside can enter the ventilation cavity formed between the outer insulation board 12 and the crack-resistant mortar 10 through the protective net 15 in the lower ventilation groove 14, and form convection with the hot air in the cavity. The hot air is discharged through the upper ventilation groove 14, which improves the heat insulation efficiency in summer by means of the "chimney effect".
