Description

Technical Field

[0001] This utility model relates to the field of thermal insulation structure technology, specifically a thermal insulation structure for building exterior walls. Background Technology

[0002] Building exterior wall insulation structure is a construction method used to improve the energy efficiency of buildings. It forms a heat insulation layer by adding insulation material to the surface of the building exterior wall to reduce the heat exchange between indoor and outdoor areas and reduce building energy consumption. This structure usually includes an insulation layer, an adhesive layer, a protective layer and a finishing layer. The insulation layer is the core part, the adhesive layer is used to fix the insulation material, the protective layer prevents the insulation layer from getting damp and mechanically damaged, and the finishing layer serves to improve aesthetics and provide further protection.

[0003] When installing the thermal insulation structure of the building's exterior walls, adhesives are usually used to firmly bond the insulation material to the exterior wall. This bonding method can ensure that the insulation layer remains stable during long-term use and effectively resist the influence of external forces such as wind and gravity, thereby preventing the insulation layer from falling off.

[0004] During the installation of building exterior wall insulation structures, construction workers typically apply adhesive to one side of the insulation material and then use fixing devices to secure it to the exterior wall. However, this installation sequence presents certain problems: before the insulation material is tightly bonded to the exterior wall, the exposed adhesive may come into contact with and adhere to dust, impurities, and other contaminants in the air. These impurities will adhere to the adhesive surface, hindering the full adhesion between the adhesive and the exterior wall when the insulation material comes into contact with it, thereby reducing the bond strength between the two and affecting the stability and insulation effect of the insulation structure. Therefore, to address the above problems, a new building exterior wall insulation structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a thermal insulation structure for building exterior walls to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A thermal insulation structure for a building exterior wall includes an insulation layer and a protective shell assembly. A thin layer of sponge is adhesively fixed to the periphery of the protective shell assembly. An extrusion assembly is adhesively fixed to the inner side of the protective shell assembly. An insert strip is inserted into the inner side of the insulation layer. The protective shell assembly includes a protective shell body. A receiving cavity and an insertion channel are formed inside the protective shell body. A needle and a spring are fixedly connected to the left end of the receiving cavity. A filling groove is formed inside the protective shell body. The extrusion assembly includes a permanent magnet plate. Flow channels are formed at both the front and rear ends of the permanent magnet plate. A rubber inclined plate is fixedly connected to the inner side of the flow channels. A plastic film is fixedly connected to the left side of the permanent magnet plate. A limit insertion hole is formed inside the permanent magnet plate.

[0008] As a further optimization of this utility model, the inner side of the filling groove of the protective shell body is filled with a heat insulation layer, the receiving cavity is located at the right end of the filling groove, and the multiple receiving cavities are connected to the insertion channel, which has a vertical structure.

[0009] As a further optimization of this utility model, the right side of the spring is fixedly connected to the permanent magnet plate by adhesive, and the diameter of the spring gradually expands from left to right.

[0010] As a further optimization of this utility model, a gap is provided between the needle and the plastic film, and the center of the needle is aligned with the left and right sides of the plastic film.

[0011] As a further optimization of this utility model, the plastic film has an adhesive storage cavity on its inner side, and the adhesive storage cavity is filled with adhesive liquid.

[0012] As a further optimization of this utility model, the permanent magnet plate is inserted into the cavity, the limiting hole is aligned vertically with the insertion channel, and the insertion strip is inserted into the insertion channel and the limiting hole.

[0013] As a further optimization of this utility model, the rubber inclined plate is an inclined structure, and the outer side of the rubber inclined plate is in contact with the inner side of the receiving cavity.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, by using a protective shell assembly and an adhesive extrusion assembly, the adhesive is bonded to the exterior wall only after the insulation structure is installed. This effectively avoids the problem of the adhesive coming into contact with and adhering to dust and impurities in the air after application. This not only improves the bonding strength between the insulation structure and the exterior wall and enhances the stability of the insulation structure, but also improves the insulation effect. At the same time, it reduces the accumulation of adhesive at the bottom of the device and improves the uniformity of the adhesive, thereby ensuring the long-term stability and energy-saving effect of the insulation structure.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figures 1-6 This utility model provides a technical solution:

[0030] A thermal insulation structure for a building exterior wall includes an insulation layer 1 and a protective shell assembly 2. A thin layer of sponge 3 is glued and fixed to the periphery of the protective shell assembly 2. An extrusion assembly 4 is glued and fixed to the inside of the protective shell assembly 2. An insert strip 5 is inserted into the inside of the insulation layer 1. The protective shell assembly 2 includes a protective shell body 21. A receiving cavity 22 and an insertion channel 25 are formed inside the protective shell body 21. A needle 23 and a spring 24 are fixedly connected to the left end of the receiving cavity 22. A filling groove 26 is formed inside the protective shell body 21. The extrusion assembly 4 includes a permanent magnet plate 41. A flow channel 42 is formed at both the front and rear ends of the permanent magnet plate 41. A rubber inclined plate 43 is fixedly connected to the inside of the flow channel 42. A plastic film 44 is fixedly connected to the left side of the permanent magnet plate 41. A limit insertion hole 46 is formed inside the permanent magnet plate 41.

[0031] As a further implementation of this solution, the inner side of the filling groove 26 opened in the protective shell body 21 is filled with the heat insulation layer 1, the receiving cavity 22 is located at the right end of the filling groove 26, and multiple receiving cavities 22 are connected to the insertion channel 25. The insertion channel 25 has a vertical structure. Through the above settings, the heat insulation effect is achieved. The connection design between the receiving cavity 22 and the insertion channel 25 facilitates the assembly of the permanent magnet plate 41 and the insertion strip 5. At the same time, the vertical setting of the insertion channel 25 avoids the opening of the flow channel 42, reducing the amount of adhesive entering the limiting insertion hole 46 and the insertion channel 25.

[0032] As a further implementation of this solution, the right side of the spring 24 is fixedly connected to the permanent magnet plate 41 by adhesive. The diameter of the spring 24 gradually expands from left to right. Through the above setting, a reasonable fixing method is provided. The shape setting of the spring 24 can reduce the space occupied by the spring 24 after the permanent magnet plate 41 squeezes the spring 24, so that most of the adhesive can be discharged.

[0033] As a further implementation of this solution, a gap is provided between the needle 23 and the plastic film 44, the center of the needle 23 is aligned with the plastic film 44 horizontally, a glue storage cavity 45 is provided inside the plastic film 44, the glue storage cavity 45 is filled with glue, the permanent magnet plate 41 is inserted into the cavity 22, the limiting insertion hole 46 is aligned vertically with the insertion channel 25, and the insertion strip 5 is inserted into the insertion channel 25 and the limiting insertion hole 46. Through the above settings, the setting of the gap between the plastic film 44 and the needle 23, and the design of the insertion strip 5 into the limiting insertion hole 46, the permanent magnet plate 41 can be prevented from moving during transportation, thereby preventing the plastic film 44 from contacting the needle 23 during transportation and causing the glue inside the glue storage cavity 45 to flow out.

[0034] As a further implementation of this solution, the rubber inclined plate 43 is an inclined structure, with the outer side of the rubber inclined plate 43 fitting against the inner side of the receiving cavity 22. Through the above arrangement, this design does not affect the discharge of the adhesive liquid, and at the same time can prevent the discharged adhesive liquid from flowing back into the receiving cavity 22, thereby ensuring that a large amount of adhesive liquid is discharged from the receiving cavity 22.

[0035] Workflow: During installation, the protective shell assembly 2 is fixed to the exterior wall using a fixing structure such as a bracket. After fixing, the sponge layer 3 adheres to the exterior wall. Then, the insert 5 is pulled out from the top through the insertion channel 25 and the limiting insertion hole 46. At this time, the permanent magnet block is placed on the left side of the protective shell body 21. The permanent magnet plate 41, aligned with the permanent magnet block, moves to the left under the action of magnetic attraction. The permanent magnet plate 41 then moves to the left against the spring 2. 4. Squeezing: The permanent magnet plate 41 slides inside the receiving cavity 22. When the plastic film 44 comes into contact with the needle 23, the needle 23 punctures the plastic film 44, causing it to burst. The adhesive inside the storage cavity 45 flows out. Under the squeezing action of the permanent magnet plate 41, the adhesive located at the left end of the permanent magnet plate 41 flows from the receiving cavity 22 into the flow channel 42. The rubber inclined plate 43 is compressed, and its right end retracts into the flow channel 42. At this time, the adhesive flows from the flow channel 4... 2. The adhesive flows out from the right end of the permanent magnet plate 41. When the permanent magnet block moves away from the permanent magnet plate 41, the spring force of the spring 24 pushes the permanent magnet plate 41 to move to the right. The adhesive inside the cavity 22 at the right end of the permanent magnet plate 41 flows out quickly. After the rubber inclined plate 43 returns to its original shape, it prevents the adhesive at the right end of the permanent magnet plate 41 from entering the flow channel 42. The outflowing adhesive enters the interior of the sponge layer 3 and diffuses inside the sponge layer 3. The setting of the sponge layer 3 can reduce the flow rate of the adhesive, thereby reducing the accumulation of adhesive at the bottom of the device and improving the uniformity of the adhesive. Based on the above principles, the device changes the traditional method of applying adhesive first and then installing. Instead, after the insulation structure is installed, the adhesive is then bonded to the exterior wall. This avoids the adhesive from coming into contact with and adhering to dust and impurities in the air, thereby improving the bonding strength between the insulation structure and the exterior wall and ensuring the stability and insulation effect of the insulation structure.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
