[0002] Building insulation is a measure to reduce the dissipation of indoor heat from a building to the outdoors. It plays an important role in creating a suitable indoor thermal environment and saving energy. Building insulation mainly takes measures on the building's exterior envelope, and building exterior wall insulation devices are an important technology for improving the energy efficiency of buildings. It reduces heat loss by adding insulation materials to the building's exterior walls.

[0003] After searching, Chinese patent announcement number: CN220644675U discloses a building exterior wall insulation device, which includes a slide rail on one side of the fixed plate that can be fixed to a specified position on the wall through a screw passing through a fixing hole. The slide rail is slidably connected to the slide bar, which facilitates the installation and disassembly of the mounting plate. The bolt is threadedly connected to the thread groove, and the bolt is rotated so that its bottom end is pressed against the upper surface of the slide bar, further fixing the expanded polystyrene board on the front side of the mounting plate to the specified position on the wall, which is convenient and quick.

[0004] However, in actual use of the above-mentioned insulation device, since the insulation board is directly placed outdoors after being laid on the exterior wall, the insulation board is greatly affected by temperature and is prone to thermal expansion and contraction. Therefore, gaps are generally left between the boards during the installation process to prevent the insulation board from thermal expansion, collapse or breakage. This makes it impossible for the insulation board to completely cover the exterior wall surface, thereby reducing the insulation effect. Therefore, a building exterior wall insulation device is proposed to solve the above-mentioned problem. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1The utility model provides an embodiment: a building exterior wall insulation device, including an insulation board 1, a side thin plate 2 is fixedly connected to the upper side of the right surface of the insulation board 1, and the insulation board 1 and the side thin plate 2 form a complete whole. The thermal expansion and contraction of the insulation board 1 can be solved by the deformation of the side thin plate 2. The thickness of the side thin plate 2 is half of the insulation board 1. The front of the side thin plate 2 is in the same horizontal plane as the front of the insulation board 1. When splicing, the side thin plate 2 of the insulation board 1 on the right is fixedly connected to the rear side of the left surface of the insulation board 1. When the insulation boards 1 on the left and right sides are moved forward When splicing, the side thin plates 2 on both sides can be tightly fitted to fill the gap between the two insulation boards 1. At the same time, a gap is left between the side thin plate 2 on the other side and the insulation board 1 on the opposite side. When the insulation board 1 expands and contracts due to thermal expansion and contraction, it can expand and deform toward the gap, which can prevent the insulation board 1 from cracking or warping due to thermal expansion and contraction during use. Fixed blocks 3 are fixedly connected to the upper and lower sides of the back side of the side thin plates 2. The fixed blocks 3 can limit the movement of the side thin plates 2 on the other side when the two insulation boards 1 are spliced ​​to ensure that there is a gap.

[0032] Reference Figure 2-Figure 3 The side thin plate 2 is provided with an L-shaped air vent 4 inside, the rear end of the L-shaped air vent 4 passes through the side thin plate 2, and the right end of the L-shaped air vent 4 also passes through the side thin plate 2, so that the air in the gap can be discharged to the outside through the L-shaped air vent 4, thereby preventing the air in the gap from expanding due to heat and causing the insulation board 1 to be stretched open, causing the insulation board 1 to warp up. A gauze 5 is fixedly connected to the right surface of the side thin plate 2, and the gauze 5 can filter the inside of the L-shaped air vent 4 to prevent dust and impurities in the air from entering the L-shaped air vent 4 and affecting the gas discharge.

[0033] A guide unit is provided on the back of the side thin plate 2, and the guide unit includes a guide block 61, which is fixedly connected to the back of the side thin plate 2. A guide groove 62 is provided on the back of the side thin plate 2. The sizes of the guide block 61 and the guide groove 62 are adapted to each other. The guide block 61 and the guide groove 62 are symmetrically arranged with the center of the side thin plate 2 as the axis of symmetry. When the two insulation boards 1 are spliced ​​left and right, the guide block 61 on one side can be aligned with the guide groove 62 on the other side. As the two insulation boards 1 gradually approach, the guide block 61 can be inserted into the guide groove 62 to guide and limit the movement of the insulation board 1, thereby avoiding the insulation board 1 from offsetting during the splicing process, thereby affecting the installation efficiency.

[0034] Reference Figure 1 and Figure 4, an L-shaped groove 7 is opened at the edge of the upper surface of the insulation board 1, and a half screw hole 8 is opened on the side of the insulation board 1. When the insulation board 1 is spliced ​​in the up and down directions, the upper half screw hole 8 can be aligned with the lower half screw hole 8 to form a complete screw hole. At the same time, the L-shaped grooves 7 on the upper and lower sides can be spliced ​​into a complete U-shaped groove. The front end of the half screw hole 8 is located inside the L-shaped groove 7. A U-shaped frame 9 is inserted into the inside of the L-shaped groove 7. When the two insulation boards 1 are spliced ​​in the upper and lower positions, the U-shaped frame 9 can be inserted into the two L-shaped grooves 7 to form a splicing shape The U-shaped frame 9 is provided with a bolt 10 on the front side, and the rear end of the bolt 10 passes through the U-shaped frame 9. The rear end of the bolt 10 is connected with the internal thread of the half screw hole 8. After the U-shaped frame 9 is installed, the bolt 10 is screwed through the complete screw hole formed to move backward and screwed into the preset installation screw hole on the wall. It can cooperate with the U-shaped frame 9 to limit the upper and lower insulation boards 1 at the same time, reducing the amount of bolts 10 and making the upper and lower adjacent insulation boards 1 form a whole, reducing the risk of falling off.

[0035] Working principle: When the insulation board 1 is spliced ​​in the left and right directions, the back of the side thin plate 2 on the left will fit together with the front of the side thin plate 2 on the right, and under the limit of the fixing block 3, a gap is formed between the two insulation boards 1. The two fitted side thin plates 2 can perform insulation and sealing treatment on the gap, and a gap is formed between the side thin plates 2 and the insulation board 1 on the other side, so that the insulation board 1 can expand and deform toward the gap after thermal expansion and contraction, avoiding cracking or warping of the insulation board 1 due to thermal expansion and contraction during use, and can increase the coverage area of ​​the insulation board 1 on the exterior wall surface, thereby improving the insulation effect. At the same time, the air in the gap is The air can be discharged to the outside through the L-shaped air vent 4, preventing the gas in the gap from expanding due to heat and affecting the deformation of the insulation board 1, or causing the insulation board 1 to tilt. When the insulation boards 1 are spliced ​​in the up and down directions, the L-shaped grooves 7 and half screw holes 8 on the two insulation boards 1 can form a complete U-shaped groove and screw holes. At this time, the U-shaped frame 9 is inserted into the U-shaped groove to preliminarily limit the two insulation boards 1. Subsequently, when the bolts 10 are screwed through the screw holes and into the preset installation screw holes on the wall, the two insulation boards 1 can be fixed, and the two adjacent insulation boards 1 above and below form a whole, reducing the risk of a single insulation board 1 falling off.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
