Description

Technical Field

[0001] This utility model relates to an air-circulating insect-proof structure for the exterior walls of wooden houses, belonging to the field of insect-proof netting technology. Background Technology

[0002] Timber structures, especially log cabins, require exterior wall designs that balance insulation, moisture control, and ventilation. To maintain air circulation within the walls and prevent moisture buildup that could lead to timber rot, a ventilated air layer is typically installed between the exterior wainscoting (or decorative panels) and the structural walls. To prevent insects such as mosquitoes and moths from entering through ventilation channels and damaging the exterior structure (e.g., gnawing on the timber, building nests), insect screens are usually installed at the entrances or exits of these ventilation channels.

[0003] Most commonly used insect nets are woven from metal wires (such as stainless steel wire and aluminum alloy wire) or synthetic fibers (such as nylon and polyester), which inherently possess a certain degree of flexibility and deformability. However, it is precisely this flexibility that leads to significant technical defects during actual installation and fixing. When tensioning and fixing the insect net to the ventilation frame or keel structure, the net is prone to unexpected bending, twisting, or collapse due to uneven stress or localized compression. This deformation often results in the net surface failing to maintain an ideal flatness, leading to the formation of tiny gaps, holes, or detachment from the fixing frame in localized areas.

[0004] Crucially, these tiny breaks or cracks (i.e., "exposed openings") caused by improper installation or material characteristics provide entry points for small insects (such as mosquitoes, ants, and wood-boring pests). Once these pests enter the ventilated air layer through these gaps, they may not only directly attach to and damage the back of the wooden exterior wall panels, but their excrement or nesting activities can also accelerate the decay process of the wood, seriously threatening the structural safety and service life of the log cabin's exterior walls. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an air-circulating insect-proof structure for the exterior walls of wooden houses. This air-circulating insect-proof structure for the exterior walls of wooden houses can avoid the deformation of insect-proof nets and reduce the risk of mosquitoes and insects damaging the wall surface.

[0006] The technical solution of this utility model is: An air-circulating insect-proof structure for the exterior wall of a wooden house includes an exterior wall surface and at least two insect-proof nets connected to the exterior wall surface. Both insect-proof nets are U-shaped to form openings, and the two openings are positioned opposite each other. At least two oppositely positioned strip fillers are also provided in the connecting direction of the two openings. The two ends of each strip filler are respectively received within the two openings. On a plane parallel to the exterior wall surface, the two insect-proof nets and the two strip fillers together form a closed airflow space with an opening facing away from the exterior wall surface. The air-circulating insect-proof structure also has a cover plate for closing the opening. Along the length of the insect-proof nets, the inner wall surface of the insect-proof nets is provided with support strips that at least partially abut against the strip fillers.

[0007] As a further improvement of this utility model, the insect-proof net includes a first fixing part fixedly connected to the outer wall surface, a second fixing part corresponding to the cover plate, and a ventilation part connecting the first fixing part and the second fixing part. The opening is formed between the first fixing part, the second fixing part and the ventilation part, and at least one of the first fixing part and the second fixing part is provided with the support strip.

[0008] As a further improvement of this utility model, in the length direction of the insect-proof net, the length of the support strip is flush with the length of the long side of the insect-proof net.

[0009] As a further improvement of this utility model, the first fixing part and the second fixing part are provided with an adhesive part on the side facing the outer wall surface, and the length of the adhesive part is flush with the length of the long side of the insect-proof net in the length direction of the insect-proof net.

[0010] As a further improvement of this utility model, the ventilation section has ventilation holes, and the ventilation holes on the two ventilation sections are interconnected to form an air circulation channel.

[0011] As a further improvement of this utility model, the support strip is a flexible metal strip that can be bent.

[0012] As a further improvement of this utility model, the cover plate and the strip filler are fixedly connected by multiple positioning elements.

[0013] As a further improvement of this utility model, a lower edge platform is also fixed at the bottom of the exterior wall surface. The lower edge platform includes a positioning plate fixedly connected to the exterior wall surface and a lower edge extending away from the exterior wall surface. The strip filler and one of the insect-proof nets are optionally fixed to the side of the positioning plate opposite to the exterior wall surface.

[0014] As a further improvement of this utility model, in the vertical direction perpendicular to the horizontal plane, the air circulation insect-proof structure includes a first insect-proof net at the top and a second insect-proof net at the bottom, and a gap is provided between the lower edge and the second insect-proof net to form an air vent.

[0015] As a further improvement of this utility model, ventilation holes are provided on both the first insect-proof net and the second insect-proof net in the vertical direction perpendicular to the horizontal plane, and the ventilation holes and the air inlets are interconnected to form an air circulation channel.

[0016] The beneficial technical effects of this utility model are as follows: The air circulation insect-proof structure for the exterior wall of a wooden house of this utility model sets a support strip on the inner wall surface of the insect-proof net, which at least partially abuts against the strip filler. The support strip straightens the insect-proof net, avoids deformation of the insect-proof net, and reduces the risk of forming tiny gaps and holes in local areas, thereby allowing mosquitoes to enter and damage the wall surface.

[0022] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] Please see Figures 1 to 5As shown, this utility model discloses an air-circulating insect-proof structure 100 for the exterior wall of a wooden house, including an exterior wall 1 and an exterior wall surface 11 formed on the exterior wall 1. An insect-proof net 2 is provided on the exterior wall surface 11. In the vertical direction perpendicular to the horizontal plane, the air-circulating insect-proof structure 100 includes a first insect-proof net at the top and a second insect-proof net at the bottom. Both the first and second insect-proof nets are U-shaped to form openings 20. The two openings 20 are arranged opposite each other. At least two oppositely arranged strip fillers 3 are also provided in the connecting direction of the two openings 20. The two ends of each strip filler 3 are respectively received within the two openings 20. In a plane parallel to the exterior wall surface 11, the two insect-proof nets 2 and the two strip fillers 3 together form a closed airflow space with an opening 23 facing away from the exterior wall surface 11. The air-circulating insect-proof structure 100 also has a cover plate 4 for closing the opening 23. In other words, the airflow space is formed between the outer wall 11, the two insect nets 2, the two strip fillers 3, and the cover plate 4.

[0024] Preferably, the length of the insect-proof net 2 is adapted to the outer wall surface 11 to cover the entire outer wall surface. Of course, the length of the insect-proof net 2 can also be adjusted according to the actual situation, and there is no limitation thereto. The two strip fillers 3 are respectively located on opposite sides of the outer wall surface 11 to ensure that mosquitoes cannot directly contact any wall surface. More other strip fillers 3 can be set between the two strip fillers 3, and there is no limitation thereto. The cover plate 4 can be a cement sealing plate for the outer wall surface.

[0025] Along the length of the insect-proof net 2, a support strip 5 is provided on the inner wall surface of the insect-proof net 2, which at least partially abuts against the strip-shaped filler 3. The support strip 5 may be an integral part of the insect-proof net 2.

[0026] In this embodiment, the insect-proof net 2 includes a first fixing part 24 fixedly connected to the outer wall surface 11, a second fixing part 25 corresponding to the cover plate 4, and a ventilation part 26 connecting the first fixing part 24 and the second fixing part 25. The opening 20 is formed between the first fixing part 24, the second fixing part 25, and the ventilation part 26. At least one of the first fixing part 24 and the second fixing part 25 is provided with the support strip 5. That is, the support strip 5 directly contacts the strip filler 3 instead of the insect-proof net 2. Of course, the thickness of the support strip 5 is very thin, so that the gap between the insect-proof net 2 and the strip filler 3 cannot allow mosquitoes to pass through.

[0027] The support strip 5 is preferably a flexible metal strip that can be bent. This design allows it to be bent without affecting the storage of the insect net 2, while also keeping the insect net 2 taut, preventing unexpected bending, twisting, or collapse due to uneven stress or localized compression. This prevents the net surface from maintaining an ideal flatness, leading to tiny gaps, holes, or detachment from the fixing frame in localized areas, allowing insects to enter and damage the exterior wall 11. While rigid metal strips can achieve the same effect, they are prone to bending during construction, continuing the aforementioned problems. Furthermore, the elasticity of the metal strip firmly presses the insect net 2 against the exterior wall surface.

[0028] Along the length of the insect-proof net 2, the length of the support strip 5 is flush with the length of the long side of the insect-proof net 2.

[0029] The cover plate 4 and the strip filler 3 are fixedly connected by a plurality of positioning elements 6. In this embodiment, the plurality of positioning elements 6 are distributed along the extension direction of the strip filler 3 to fix the cover plate 4 to the strip filler 3, thereby firmly restricting the second fixing part 25 of the insect net 2. The positioning elements 6 can be screws or other clips, and there is no limitation thereto.

[0030] The first fixing part 24 and the second fixing part 25 are provided with an adhesive part 241 on the side facing the outer wall surface 11. In the length direction of the insect-proof net 2, the length of the adhesive part 241 is flush with the length of the long side of the insect-proof net 2. The adhesive part 241 is preferably an adhesive strip, which makes it easier to install and use.

[0031] The bottom of the exterior wall 11 is also fixed with a lower edge platform 7. The lower edge platform 7 includes a positioning plate 71 fixedly connected to the exterior wall 11 and a lower edge 72 extending away from the exterior wall 11. The strip filler 3 and the second insect net are optionally fixed to one side of the positioning plate 71 relative to the exterior wall 11.

[0032] In the vertical direction perpendicular to the horizontal plane, both the first and second insect-proof nets have ventilation holes on their ventilation sections 26. A gap is provided between the lower edge 72 and the second insect-proof net to form an air vent 27. The ventilation holes and the air vent 27 are interconnected to form an air circulation channel. Specifically, the ventilation holes, the airflow space, and the air vent 27 are interconnected to form an air circulation channel.

[0033] In summary, the air-circulating insect-proof structure 100 for the exterior wall of a wooden house of this utility model provides a support strip 5 on the inner wall surface of the insect-proof net 2, which at least partially abuts against the strip filler 3. The support strip 5 straightens the insect-proof net, avoiding deformation of the insect-proof net 2, thereby reducing the risk of forming tiny gaps and holes in local areas, which would allow mosquitoes to enter and damage the wall.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
