Description

Technical Field

[0001] The utility model relates to the technical field of building thermal insulation, in particular to a passive building exterior wall thermal insulation structure. Background Art

[0002] Passive buildings mainly refer to building equipment that does not rely on its own energy consumption, but achieves building energy conservation entirely through the design of the building's own spatial form, enclosure structure, building materials and structure, such as using designs such as sunshade, wall insulation, and natural ventilation. In some areas with lower temperatures, insulation boards are often installed on the outside of buildings. The insulation boards in the prior art include bonding with adhesive mortar and fixing with rivets. When the insulation boards are directly bonded, it is not convenient to replace the insulation boards when local damage occurs. Although rivet fixing makes it convenient to replace the locally damaged insulation boards, the rivets need to be disassembled and reassembled when replacing the insulation boards, which makes the replacement operation of the insulation boards inconvenient. Therefore, a passive building exterior wall insulation structure is proposed to address the above problems. Utility Model Content

[0024] Example 2

[0025] like Figure 1 , Figure 2 and Figure 5As shown, in order to solve the problem that it is inconvenient to control the four piston blocks 7 to be stuck on the outside of the corresponding positioning nails 8 at the same time, the top of the insulation board 1 is rotatably connected with a handle 3, and the handle 3 passes through the insulation board 1 and the fixed plate 2, the handle 3 is rotatably connected to the fixed plate 2, and the bottom of the handle 3 is fixedly connected with a driving bevel gear 4, and the outside of the driving bevel gear 4 is meshed with a driven bevel gear 5, and the driven bevel gear 5 is fixedly connected to the fixed threaded shaft 6. The driving bevel gear 4 is driven by the handle 3 to mesh with the four driven bevel gears 5, and the four fixed threaded shafts 6 are further driven to be spirally connected with the corresponding piston blocks 7 at the same time, which facilitates the simultaneous control of the four piston blocks 7 to be stuck on the outside of the corresponding positioning nails 8.

[0026] Example 3

[0027] like Figure 1-5 As shown, in order to solve the problem of poor air tightness between adjacent devices, a sealing ring 9 is fixedly connected to the outside of the insulation board 1, and the sealing ring 9 is made of rubber. By arranging the sealing ring 9 made of rubber on the outside of the device, the air tightness between adjacent devices is improved.

[0028] Example 4

[0029] like Figure 3-6 As shown, in order to solve the problem that it is inconvenient to remove the damaged insulation board 1 from between the insulation boards 1 on the outer sides, an air pipe 10 is arranged between the adjacent piston blocks 7, and the air pipe 10 is fixedly connected to the fixed plate 2, one end of the air pipe 10 is connected to a fixed block 11, and the fixed block 11 passes through the fixed plate 2 and the insulation board 1, the fixed block 11 is fixedly connected to the fixed plate 2 and the insulation board 1, and a rubber pad 12 is fixedly connected to the bottom end of the inner side of the fixed block 11, and air is pressed into the fixed block 11 through the air pipe 10 in the process of controlling the piston block 7 to slide away from the outer side of the nail cap of the positioning nail 8, and the rubber pad 12 is further contacted with the wall surface first, and then the rubber pad 12 is expanded. At this time, the insulation board 1 is pushed in the removal direction of the insulation board 1 by the expanded rubber pad 12, so that the damaged insulation board 1 is conveniently removed from between the insulation boards 1 on the outer sides.

[0030] Example 5
