Description

Technical Field

[0001] This utility model relates to the technical field of self-locking aerocondensing felt insulation structure, specifically to a self-locking aerocondensing felt insulation structure. Background Technology

[0002] Aerogel is a novel nanoporous material with excellent performance. Aerogel felt is a flexible thermal insulation felt made of nano-silica as the main material and combined with carbon fiber, ceramic glass fiber cotton or pre-oxidized fiber felt through a special process.

[0003] Because aerogel felt has nanoscale pores and a loose structure on its surface, dust is easily shed during use. This not only adversely affects the stability of the material's thermal insulation performance, but also pollutes indoor air. Long-term exposure to such an environment may pose potential health risks to the respiratory system. To address these issues, we have proposed a self-locking aerogel felt insulation structure. Utility Model Content

[0004] The present invention aims to provide a self-locking aerogel felt insulation structure to solve the problem that aerogel felt is prone to dust shedding during use, which not only adversely affects the stability of the material's insulation performance but also pollutes indoor air.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a self-locking aerogel felt insulation structure, including an insulation layer, a reinforcing mesh, and several fasteners. The insulation layer includes an aerogel felt, and the fasteners include a bolt rod and a nut sleeve that matches the bolt rod. The bolt rod is located at one end of the insulation layer, and the nut sleeve passes through the aerogel felt and is located at the other end of the insulation layer. The bolt rod and the nut sleeve are threadedly connected. The reinforcing mesh is wrapped around the insulation layer. The outer wall of the reinforcing mesh is coated with cement mortar or organic adhesive to form a wrapping layer, or the outer wall of the reinforcing mesh is wrapped with an air-barrier membrane to form a wrapping layer.

[0006] The beneficial effects of this solution are as follows: Aerogel, as an excellent thermal insulation material, has superior thermal insulation performance at the same thickness, with an insulation effect 2 to 5 times that of traditional thermal insulation materials, and a longer service life. To achieve the same thermal insulation effect, the thickness of aerogel felt is only one-fifth to one-third of that of traditional thermal insulation materials. In this solution, a snap-fit ​​connector consisting of a bolt rod and a nut sleeve is used. The bolt rod and nut sleeve are respectively placed on both sides of the aerogel felt, with the nut sleeve penetrating the aerogel felt and the bolt rod threadedly connecting it. This improves the installation efficiency of the self-locking aerogel felt insulation structure, ensuring that the thickness of the aerogel felt is consistent throughout after tightening the snap-fit ​​connector, thus improving the flatness of the insulation structure fixed to the wall. Using a wrapping layer to enclose the reinforcing mesh can prevent dust shedding from the aerogel felt during use.

[0007] Preferably, as an improvement, the length of the nut sleeve is greater than the length of the bolt shank.

[0008] The beneficial effects are as follows: the length of the nut sleeve is greater than the length of the bolt shank. When the bolt shank is fully screwed into the nut sleeve, there is still a part of the threaded section of the nut sleeve that does not contact the bolt shank, forming a redundant engagement space. This avoids the problem of loose connection caused by machining errors and ensures that the threads of the bolt shank and the nut sleeve can fully engage.

[0009] Preferably, as an improvement, the insulation layer further includes several thickness-fixed components, which are evenly arranged inside the aerogel felt, and the height of the thickness-fixed components is less than the thickness of the aerogel felt. The nut sleeve passes through the thickness-fixed components and is located at the other end of the insulation layer.

[0010] The beneficial effects are: by placing the fixed-thickness component inside the aerogel felt, making it an internal support structure for the aerogel felt, the deformation resistance of the insulation layer is enhanced, its structural stability is improved, and the risk of damage during use is reduced.

[0011] Preferably, as an improvement, the reinforcing mesh is wrapped around the outer wall of the aerogel felt, the bolt rod is located at one end of the reinforcing mesh, the nut sleeve is located at the other end of the reinforcing mesh through the thickness-fixed part, and the bolt rod and the nut sleeve are threadedly connected.

[0012] Preferably, as an improvement, it also includes several fixing components that connect the self-locking aerocondensing felt insulation structure to the wall. The fixing components include mounting blocks and insertion blocks. The mounting blocks are fixedly installed on the upper end of the wall. The mounting blocks have insertion slots. The insertion blocks are located on the outer wall of the wrapping layer. The insertion blocks can be inserted into the insertion slots. The mounting blocks have sliding slots that communicate with the insertion slots. The sliding slots have abutment members. The insertion blocks have trigger slots. The trigger slots have trigger members. The trigger members can cause the abutment members to push the insertion blocks, thereby making the insertion blocks fit tightly against the inner wall of the insertion slots.

[0013] The beneficial effects are as follows: To improve the installation efficiency of thermal insulation structures, existing technologies typically use an insert-type installation method to fix the thermal insulation structure to the wall. Compared with bolt fixing, this method significantly improves installation efficiency. However, because the insert-type installation method is prone to gaps between the insert block and the slot, the thermal insulation structure may wobble when installed on the wall, and the thermal insulation structure of an entire wall may be uneven due to the gaps in the insert-type installation. In this solution, when the insert block is inserted into the insertion slot of the installation block, the trigger and the abutment interact, causing the abutment to push the insert block, making the insert block fit tightly against the inner wall of the insertion slot. This eliminates the gap between the insert block and the insertion slot, greatly improving the connection strength between the thermal insulation structure and the wall, effectively preventing loosening or displacement caused by external forces, ensuring that the thermal insulation structure is stably fixed to the wall for a long time. Furthermore, when the insert block fits against the inner wall of the insertion slot, the thermal insulation structure remains parallel to the wall surface, thus avoiding angular deviations between adjacent thermal insulation structures and improving the flatness of the thermal insulation structure during installation.

[0014] Preferably, as an improvement, the abutting component includes a support rod, an abutting block, a lifting block, and two first wedge blocks and a second wedge block. The support rod is located at the end of the sliding groove away from the insertion groove. A reset cavity is formed inside the abutting block. One end of the support rod passes through the abutting block and extends into the reset cavity. A limiting block is provided at the end of the support rod extending into the reset cavity. A first spring is sleeved on the outer wall of the support rod, and the first spring is located between the limiting block and the reset cavity. Two first wedge blocks are symmetrically arranged at the end of the abutting block near the support rod. The mounting block has a lifting groove that communicates with the sliding groove. The lifting block is slidably installed in the lifting groove. Two second wedge blocks are symmetrically arranged at the lower end of the lifting block, and the second wedge blocks abut against the first wedge blocks. When the second wedge blocks move downward, the first wedge blocks push the abutting block to extend into the insertion groove and abut against the insertion block.

[0015] The beneficial effects are as follows: the support rod passes through the abutment block and limits the displacement range of the abutment block through the limiting block, providing stable guiding support for the abutment block and preventing the abutment block from tilting or bending when under force. The two second wedge blocks abut symmetrically with the first wedge block. When the lifting block moves downward, the inclined surface of the second wedge block squeezes the first wedge block, converting the vertical driving force into the horizontal thrust, pushing the abutment block to accurately extend into the insertion slot and abut tightly with the insertion block, thereby eliminating the gap between the insertion block and the insertion slot, greatly improving the connection strength between the insulation structure and the wall, and effectively preventing loosening or displacement caused by external forces.

[0016] Preferably, as an improvement, the triggering component includes a connecting plate, a trigger plate, and a pin. The connecting plate is slidably installed in the trigger groove. Several second springs are provided between the upper end of the connecting plate and the upper wall of the trigger groove. The lower end of the insertion block has a through groove that communicates with the trigger groove. The trigger plate is located at the lower end of the connecting plate and can extend out of the through groove to contact the lifting block. The lower end of the insertion block has a locking groove that communicates with the through groove. The pin is slidably installed in the locking groove. The lower end of the pin has a trapezoidal block. The upper end of the mounting block has a shaped groove that matches the trapezoidal block.

[0017] The beneficial effects are as follows: when the insert block is inserted into the insertion slot of the mounting block, the trapezoidal block at the lower end of the pin moves down with the insert block and contacts the inclined surface of the irregular groove. At this time, the pin slides along the inclined surface of the irregular groove. When the insert block is fully inserted into the insertion slot, the pin separates from the trigger plate, and then the trigger plate extends out of the through slot and contacts the lifting block under the action of several second springs. The lifting block slides down along the lifting groove, and then the action of the second wedge block and the first wedge block drives the abutment block to extend and press against the insert block.

[0018] Preferably, as an improvement, the first wedge block has a guide block at one end near the second wedge block, and the second wedge block has a guide groove at one end near the first wedge block that matches the guide block.

[0019] The beneficial effect is that after the guide block is embedded in the guide groove, it can limit the relative offset between the first wedge block and the second wedge block in the horizontal and vertical directions, ensuring that the first wedge block and the second wedge block only slide relative to each other along the inclined plane direction.

[0020] Preferably, as an improvement, the inner wall of the lifting groove is symmetrically provided with sliding grooves, and the lifting block is slidably installed between the two sliding grooves. Attached Figure Description

[0023] Example 1 Example 1 is basically as shown in the appendix. Figures 1-2 As shown, Figure 1 The self-locking aerogel insulation structure shown includes an insulation layer, a reinforcing mesh 33, and several clips for fixing the insulation layer within the reinforcing mesh 33. The insulation layer includes an aerogel felt 2 and several thickness-fixed components 3. The thickness of the aerogel felt 2 is set to 10-25mm. The aerogel felt 2 can also be replaced with cement-based aerogel insulation board, inorganic foamed aerogel insulation board, etc. The outer wall of the aerogel felt 2 has several holes, and the thickness-fixed components 3 are fixedly installed inside the aerogel felt 2 through each hole. The horizontal and vertical spacing of each thickness-fixed component 3 is set to 100-600mm. The thickness-fixed components 3 are tubular, with a channel in the middle of each thickness-fixed component 3. The height of component 3 is less than the thickness of aerogel felt 2. The snap-fit ​​component includes a bolt rod 5 and a nut sleeve 6 that matches the bolt rod 5. The bolt rod 5 is located on the left side of the insulation layer, and its left end extends through the aerogel felt 2 into the thickness-fixing component 3. The nut sleeve 6 is located on the right side of the insulation layer, and its left end extends through the aerogel felt 2 into the thickness-fixing component 3. The length of the nut sleeve 6 is greater than the length of the bolt rod 5. When the bolt rod 5 is fully screwed into the nut sleeve 6, a portion of the threaded section of the nut sleeve 6 remains uncontacted with the bolt rod 5, creating redundant engagement space. This avoids loose connections due to machining errors and ensures that the threads of the bolt rod 5 and the nut sleeve 6 can fully engage. Figure 2 The bolt rod 5 shown has a cross groove 7 at its end. By rotating the bolt rod 5 with a screwdriver, the bolt rod 5 is threadedly connected to the nut sleeve 6. The reinforcing mesh 33 is wrapped around the insulation layer and the outer wall of the snap-fit ​​component. The thickness of the reinforcing mesh 33 is set to 0.5-15mm. Of course, the reinforcing mesh 33 can also be set as a bag with an opening. The aerogel felt 2 is placed inside the bag-shaped reinforcing mesh 33, and then the opening of the reinforcing mesh 33 is sealed with yarn, thereby sealing the aerogel felt 2 inside the reinforcing mesh 33. The reinforcing mesh 33 is set as an alkali-resistant fiberglass breathable membrane. In this embodiment, the insulation structure can be directly pasted to the wall with cement mortar, which greatly improves the installation efficiency of the insulation structure. Figure 1The outer wall of the reinforcing mesh 33 shown is coated with cement mortar or organic adhesive to form a wrapping layer 1. The organic adhesive is set as polyurethane adhesive, epoxy resin adhesive, etc. The thickness of the wrapping layer 1 is set to 0.5-1.5mm. Of course, an air-barrier membrane can also be used to wrap the outer wall of the reinforcing mesh 33. The air-barrier membrane can be set as a building waterproof and breathable membrane, geotextile, alkali-resistant fiberglass reinforced mesh composite geotextile, skeleton non-woven fabric, polyester fiber felt, PVC fiberglass coated felt, cement fiberglass coated felt, etc. The wrapping layer 1 serves as a rigid support for the insulation layer and can protect the reinforcing mesh 33, preventing the reinforcing mesh 33 from being torn and exposing the insulation layer.

[0024] By placing the thickness fixing part 3 inside the aerogel felt 2, the thickness of the aerogel felt 2 is kept consistent throughout after being tightened by the snap fasteners, thereby improving the flatness of the insulation structure fixed to the wall. The thickness fixing part 3 can also serve as an internal support structure, enhancing the deformation resistance of the insulation layer, improving its structural stability, and reducing the risk of damage during use. Wrapping the reinforcing mesh 33 with the wrapping layer 1 can prevent the aerogel felt 2 from shedding dust during use.

[0025] Example 2 Example 2 is largely the same in principle as Example 1, the difference being: Figure 3 The reinforcing mesh 33 shown is wrapped around the outer wall of the aerogel felt 2. The bolt rod 5 is located at the left end of the reinforcing mesh 33, and the nut sleeve 6 is located at the right end of the reinforcing mesh 33. The left end of the nut sleeve 6 extends through the reinforcing mesh into the thickness fixing member 3. The ends of the bolt rod 5 and the nut sleeve 6 protrude completely from the outer wall of the reinforcing mesh 3 or are partially embedded in the outer wall of the reinforcing mesh 3. The bolt rod 5 is threaded through the reinforcing mesh 33 and connected to the nut sleeve 6. By inserting the snap-fit ​​member through the reinforcing mesh 33 and the thickness fixing member 4, the aerogel felt 2 can be fixed in a specific position in the reinforcing mesh 33 to prevent the aerogel felt 2 from shifting or piling up inside the reinforcing mesh 33.

[0026] Example 3 Example 3 is largely the same in principle as Example 2, the difference being: Figure 4 As shown, it also includes several fixing components that connect the self-locking aerocondensing felt insulation structure to the wall. The fixing components include mounting blocks 8 and insertion blocks 9. Mounting blocks 8 are fixed to the upper part of the wall by welding or expansion screws, as shown. Figure 5The mounting block 8 shown has an insertion slot 10. The insertion block 9 is fixedly installed on the outer wall of the wrapping layer 1. The lower end of the insertion block 9 can be inserted into the insertion slot 10. The right end of the mounting block 8 has a sliding groove 11 that communicates with the insertion slot 10. The sliding groove 11 has an abutment, which includes a support rod 12, an abutment block 13, a lifting block 14, and two first wedge blocks 15 and a second wedge block 16. The support rod 12 is fixedly installed on the right wall of the sliding groove 11. The right end of the abutment block 13 has a reset cavity 17, which is cylindrical. The left end of the support rod 12 passes through the abutment block 13 and extends into the reset cavity 17. The left end of the support rod 12 is fixedly installed with a limit block 18, which is cylindrical and matches the reset cavity 17. The outer wall of the support rod 12 is fitted with a first spring 19, and the left end of the first spring 19 is fixedly connected to the limit block 18. The right end of the first spring 19 is fixedly connected to the inner wall of the reset cavity 17. The two first wedge blocks 15 and 16 are fixedly connected to the inner wall of the reset cavity 17. Block 15 is symmetrically fixedly installed on the right end of abutment block 13. A lifting groove 20 communicating with sliding groove 11 is provided on the upper end of mounting block 8. Sliding grooves 21 are symmetrically provided on the front and rear inner walls of the lifting groove 20. Lifting block 14 is slidably installed between the two sliding grooves 21. Two second wedge blocks 16 are symmetrically fixedly installed on the lower end of lifting block 14, and the second wedge blocks 16 abut against the first wedge block 15. When the second wedge block 16 moves downward, the first wedge block 15 pushes the abutment block 13. 3. The first wedge block 15 is inserted into the insertion groove 10 and abuts against the insertion block 9. A guide block 22 is fixedly installed on the right end of the first wedge block 15. The guide block 22 is set as a semi-cylindrical shape. The left end of the second wedge block 16 is provided with a guide groove 23 that matches the guide block 22. After the guide block 22 is embedded in the guide groove 23, it can limit the relative offset between the first wedge block 15 and the second wedge block 16 in the horizontal and vertical directions, ensuring that the first wedge block 15 and the second wedge block 16 only slide relative to each other along the inclined plane direction.

[0027] like Figure 6 The insertion block 9 shown has a trigger groove 24 inside, and a trigger element is provided in the trigger groove 24. The trigger element can cause the abutment to push the insertion block 9, thereby making the insertion block 9 fit tightly against the inner wall of the insertion groove 10. The trigger element includes a connecting plate 25, a trigger plate 26, and a pin 27. The connecting plate 25 is slidably installed in the trigger groove 24. Several second springs 28 are fixedly installed between the upper end of the connecting plate 25 and the upper wall of the trigger groove 24. The lower end of the insertion block 9 has a through groove 29 that communicates with the trigger groove 24. The trigger plate 26 is fixedly installed at the lower end of the connecting plate 25, and the trigger plate 26 can extend out of the through groove 29 to abut against the lifting block 14. The lower end of the insertion block 9 has a locking groove 30 that communicates with the through groove 29. The pin 27 is slidably installed in the locking groove 30. A trapezoidal block 31 is fixedly installed on the lower right side of the pin 27. Figure 4 The mounting block 8 shown has an irregular groove 32 at its upper end that matches the trapezoidal block 31, and the inclined surface of the trapezoidal block 31 is tangent to the inclined surface of the irregular groove 32.

[0028] To improve the installation efficiency of thermal insulation structures, existing technologies typically employ an insert-type installation method to fix the insulation structure to the wall. This method significantly improves installation efficiency compared to bolt fixing. However, the insert-type installation method is prone to gaps between the insert block and the slot, causing the insulation structure to wobble when installed on the wall, and resulting in unevenness of the insulation structure across the entire wall due to the gaps. In this solution, when the insert block 9 is inserted into the insertion slot 10 of the mounting block 8, the trapezoidal block 31 at the lower end of the pin 27 moves down with the insert block 9 and contacts the inclined surface of the irregular groove 32. At this time, the pin 27 moves along the inclined surface of the irregular groove 32. When sliding occurs, as the insertion block 9 is fully inserted into the insertion slot 10, the pin 27 separates from the trigger plate 26. This causes the trigger plate 26 to extend out of the through slot 29 and contact the lifting block 14 under the action of several second springs 28. The lifting block 14 then slides downward along the lifting slot 20, causing the inclined surface of the second wedge block 16 to press against the first wedge block 15. This converts the vertical driving force into a horizontal thrust, pushing the abutment block 13 to precisely extend into the insertion slot 10 and tightly abut against the insertion block 9. This eliminates the gap between the insertion block 9 and the insertion slot 10, significantly improving the connection strength between the insulation structure and the wall, and effectively preventing loosening or displacement caused by external forces.

[0029] When the insertion block 9 is inserted into the insertion slot 10 of the mounting block 8, the trigger and the abutment interact, causing the abutment to push the insertion block 9, making the insertion block 9 fit tightly against the inner wall of the insertion slot 10. This eliminates the gap between the insertion block 9 and the insertion slot 10, significantly improving the connection strength between the insulation structure and the wall. It effectively prevents loosening or displacement caused by external forces, ensuring that the insulation structure is stably fixed to the wall for a long time. Furthermore, when the insertion block 9 fits against the inner wall of the insertion slot 10, the insulation structure remains parallel to the wall surface, thus avoiding angular deviations between adjacent insulation structures and improving the flatness of the insulation structure during installation.
