[0002] In the field of construction, thermal insulation materials play a crucial role in reducing building energy consumption and improving indoor living comfort. Aerogel is a new type of functional material with a three-dimensional nano-porous structure. Its outstanding properties such as extremely low thermal conductivity, high porosity and low density make it stand out in the field of materials. Among the derivative products of aerogel, aerogel felt is a flexible thermal insulation material composed of nanosilica as the core substrate and carbon fiber, ceramic glass fiber or pre-oxidized fiber felt through special process. This material has great application potential in the field of thermal insulation, making it have wide application prospects in the field of construction.

[0003] Due to the existence of nano-scale pores and loose structure on the surface of aerogel felt, dust shedding is likely to occur during use, which not only has adverse effects on the stability of the material's own thermal insulation performance, but also pollutes indoor air. Long-term exposure of human body to such an environment may pose potential harm to respiratory health. Therefore, we propose a binding type aerogel felt insulation board to solve the above problems. SUMMARY

[0005] To achieve the above purpose, the technical scheme adopted by the present application is as follows: a binding type aerogel felt insulation board, comprising a thermal insulation layer, a reinforcing net and a plurality of clamping pieces, the thermal insulation layer comprising aerogel felt and a plurality of thickness-determining pieces, the plurality of thickness-determining pieces being evenly arranged in the aerogel felt, the height of the thickness-determining piece being less than the thickness of the aerogel felt, the thickness-determining piece being symmetrically provided with two channels, the clamping piece comprising a fixing seat and a strap, the fixing seat being arranged at one end of the aerogel felt, one end of the strap being arranged at the end of the fixing seat close to the aerogel felt, the fixing seat being provided with a lock hole, the lock hole being provided with a lock tooth, the outer wall of the end of the strap away from the fixing seat being provided with a plurality of clamping teeth, the end of the strap with the clamping teeth being capable of sequentially penetrating the two channels and being clamped with the lock tooth in the lock hole, the reinforcing net being wrapped around the outer wall of the thermal insulation layer and each clamping piece, the outer wall of the reinforcing net being coated with a cement mortar or an organic glue to form a wrapping layer, or the outer wall of the reinforcing net being wrapped with an air-tight film to form a wrapping layer.

[0008] The beneficial effects are: the fixed thickness piece is arranged in the aerogel blanket, so that the aerogel blanket fastened by the clamping piece is consistent in height with the fixed thickness piece, thereby improving the flatness of the insulation board fixed on the wall, the fixed thickness piece can also serve as an internal support structure of the aerogel blanket, enhancing the anti-deformation ability of the insulation layer and improving the structural stability to reduce the risk of damage during use. Preferably, as an improvement, the fixing seat is disc-shaped, the fixed thickness piece is cylindrical, and the diameter of the fixing seat is greater than or equal to the diameter of the fixed thickness piece.

[0009] The beneficial effects are: when the cable tie penetrates the two channels of the fixed thickness piece at one time and is locked with the locking hole of the fixing seat, the fixing seat disperses the fastening force to the fixed thickness piece and the reinforcing net around it through the circular contact surface, which can avoid the aerogel blanket being crushed and damaged due to excessive local stress, while ensuring that the aerogel blanket is uniformly compressed to be consistent in height with the fixed thickness piece, thereby ensuring the uniformity of the thickness of the insulation layer.

[0011] The beneficial effects are: by arranging the pressing block in the channel of the fixed thickness piece, the pressing block keeps the cable tie straight in the channel, ensuring stable transmission of the tightening force of the cable tie, thereby avoiding bending of the cable tie in the channel of the fixed thickness piece, which may cause gaps between the reinforcing net and the aerogel blanket, and cause the aerogel blanket to deviate, and when the cable tie exposed outside the reinforcing net is pulled by external force, the locking teeth in the two channels provide resistance first, so that the stress borne by the cable tie in the locking hole is reduced, thereby avoiding the cable tie from breaking in the locking hole, and prolonging the service life of the clamping piece.

[0012] Preferably, as an improvement, the reinforcing net is wrapped outside the outer wall of the thermal insulation layer, the fixing seat is arranged at one end of the reinforcing net, and the end of the cable tie with the clamping teeth penetrates through the reinforcing net and the thickness fixing piece and is clamped with the locking teeth in the locking hole.

[0013] The beneficial effect is that the clamping piece tightly binds the thermal insulation layer in the reinforcing net by penetrating the cable tie through the reinforcing net and the thickness fixing piece, effectively avoiding the imbalance of thermal insulation performance caused by the offset of the thermal insulation layer in the reinforcing net, and prolonging the service life of the air-laid felt thermal insulation board.

[0014] Preferably, as an improvement, the fixing assembly for connecting the air-laid felt thermal insulation structure and the wall includes a mounting block and an insertion block, the mounting block is fixedly installed on the upper end of the wall, the mounting block is provided with an insertion slot, the insertion block is arranged on the outer wall of the fixing seat and can be inserted into the insertion slot, the mounting block is provided with a sliding slot in communication with the insertion slot, the sliding slot is provided with an abutting piece, the insertion block is provided with a triggering slot, the triggering slot is provided with a triggering piece, and the triggering piece can push the insertion block to tightly fit the inner wall of the insertion slot.

[0015] The beneficial effect is that in order to improve the installation efficiency of the thermal insulation structure, the prior art usually adopts an insertion type installation method to fixedly install the thermal insulation structure on the wall, which greatly improves the installation efficiency compared with the bolt fixing method, but the insertion type installation method is prone to gaps between the clamping block and the clamping slot, resulting in shaking of the thermal insulation structure when installed on the wall, and unevenness of the thermal insulation structure of the entire wall due to the installation gap of the insertion type. In the present scheme, after the insertion block is inserted into the insertion slot of the mounting block, the triggering piece and the abutting piece interact, the abutting piece pushes the insertion block, the insertion block tightly fits the inner wall of the insertion slot, thereby eliminating the gap between the insertion 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 force, ensuring that the thermal insulation structure is stably fixed on the wall for a long time, and when the insertion block and the inner wall of the insertion slot are fitted, the thermal insulation structure is parallel to the wall surface, thereby avoiding the angle deviation of adjacent thermal insulation structures and improving the flatness during installation of the thermal insulation structure.

[0017] The beneficial effects are that the supporting rod penetrates through the abutting block and limits the displacement range of the abutting block through the limiting block, thereby providing stable guiding support for the abutting block, avoiding the abutting block from being deflected or bent when being stressed, and the two second wedge-shaped blocks symmetrically abut against the first wedge-shaped blocks, when the lifting block moves downward, the inclined surface of the second wedge-shaped block extrudes the first wedge-shaped block, thereby converting the driving force in the vertical direction into the thrust in the horizontal direction, pushing the abutting block to accurately penetrate into the insertion groove and tightly abut against the insertion block, thereby eliminating the gap between the insertion block and the insertion groove, greatly improving the connection strength between the heat preservation structure and the wall, and effectively preventing loosening or displacement caused by external force.

[0019] The beneficial effects are that when the insertion block is inserted into the insertion groove of the mounting block, the trapezoidal block at the lower end of the plug moves downward with the insertion block and contacts the inclined surface of the special-shaped groove, at this time, the plug slides along the inclined surface of the special-shaped groove, when the insertion block is completely inserted into the insertion groove, the plug is separated from the trigger plate, thereby causing the trigger plate to extend out of the through groove to contact the lifting block under the action of the plurality of second springs, and causing the lifting block to slide downward along the lifting groove, thereby driving the abutting block to extend out and tightly abut against the insertion block through the action of the second wedge-shaped block and the first wedge-shaped block.

[0025] Example 1 Example 1 is basically as shown in the appendix. Figures 1-2 As shown, Figure 1The illustrated one kind is tied type aerogel felt insulation board, including thermal insulation layer, reinforcing net 3 and several fixing and installing the clamping piece of thermal insulation layer in reinforcing net 3, thermal insulation layer includes aerogel felt 2 and several thickness piece 4, the thickness of aerogel felt 2 is set to 10-25mm, aerogel felt 2 can also be replaced into cement-based aerogel insulation board, inorganic foaming aerogel insulation board and so on, aerogel felt 2 outer wall is provided with several holes, several thickness piece 4 is fixedly installed in aerogel felt 2 through each hole, and the horizontal and vertical spacing of each thickness piece 4 is set to 100-600mm, thickness piece 4 is set to cylindrical, and the height of thickness piece 4 is less than the thickness of aerogel felt 2, thickness piece 4 is symmetrically penetrated and provided with two channels 11, such as Figure 2 The illustrated clamping piece includes fixed seat 6 and tie 7, fixed seat 6 is located at the right end of aerogel felt 2, fixed seat 6 is set to disc shape, and the diameter of fixed seat 6 is greater than or equal to the diameter of thickness piece 4, the left end of tie 7 is fixedly installed on the lower side of the right end of fixed seat 6, of course, tie 7 and fixed seat 6 can be made by one-piece molding technology, fixed seat 6 is penetrated and provided with lock hole 8, lock tooth 9 is fixedly installed in lock hole 8, the left end upper wall of tie 7 is uniformly fixedly installed with several clamping teeth 10, such as Figure 1 The illustrated tie 7 has one end of clamping tooth 10 and can be penetrated and clamped with lock tooth 9 in lock hole 8 in sequence, reinforcing net 3 is wrapped on the outer wall of thermal insulation layer and each clamping piece, the thickness of reinforcing net 3 is set to 0.5-15mm, of course, reinforcing net 3 can also be set to a bag with an opening, aerogel felt 2 is loaded into the bag-shaped reinforcing net 3, and then the opening of reinforcing net 3 is sealed by weaving wire, so that aerogel felt 2 is sealed in reinforcing net 3, reinforcing net 3 is set to alkali-resistant glass fiber breathable membrane, non-woven fabric.

[0026] As shown in the figure Figure 1 The outer wall of the reinforcing net 3 is coated with cement mortar or organic glue to form a wrapping layer 1, the organic glue is set to polyurethane glue, epoxy resin glue, etc., the thickness of the wrapping layer 1 is set to 0.5-1.5mm, of course, the outer wall of the reinforcing net 3 can also be wrapped with an air barrier film, the air barrier film can be set to a building waterproof breathable membrane, a geotextile, an alkali-resistant glass fiber reinforced net composite geotextile, a skeleton non-woven fabric, a polyester fiber thin felt, a PVC glass fiber coating felt, a cement glass fiber coating felt, etc., the wrapping layer 1 serves as a hard support for the thermal insulation layer, which can protect the reinforcing net 3 from being torn and exposing the thermal insulation layer.

[0027] The specific implementation process is as follows: The aerogel felt 2 is fixed by mechanically engaging the clips 10 of the cable tie 7 with the locking teeth 9 of the locking hole 8. This physical connection is unaffected by temperature and humidity fluctuations. The cable tie 7 passes through the two channels 11 of the thickness-fixing component 4 and locks into the fixing base 6, placing the thickness-fixing component 4 inside the aerogel felt 2. This ensures that the height of the aerogel felt 2 and the thickness-fixing component 4 are consistent after being secured by the clips, thereby improving the flatness of the insulation board fixed to the wall. The thickness-fixing component 4 can also serve as an internal support structure for the aerogel felt, enhancing the deformation resistance of the insulation layer, improving its structural stability, and reducing the risk of damage during use. Wrapping the reinforcing mesh 3 with the wrapping layer 1 can prevent the aerogel felt 2 from shedding dust during use. By fixing one end of the cable tie 7 to the fixing base 6, and then passing the other end through the two channels 11 of the thickness-fixing component 4, and finally inserting it into the locking hole 8, the clips 10 and locking teeth 9 can be used for engagement and fixation. No complicated installation tools are required, which improves the efficiency of producing aerogel felt insulation boards.

[0028] Example 2 Example 2 is largely the same in principle as Example 1, the difference being: Figure 3 The reinforcing mesh 3 shown is wrapped around the outer wall of the insulation layer. The fixing seat 6 is located at the right end of the reinforcing mesh 3. One end of the cable tie 7 with the locking teeth 10 passes through the reinforcing mesh 3 and the thickness fixing member 4 and engages with the locking teeth 9 in the locking hole 8. By passing the cable tie 7 through the reinforcing mesh 3 and the thickness fixing member 4, the locking member firmly binds the insulation layer inside the reinforcing mesh 3, effectively avoiding the imbalance of insulation performance caused by the insulation layer shifting inside the reinforcing mesh 3, and making the service life of the aerocondensed felt insulation board longer.

[0029] Example 3 Example 3 is largely the same in principle as Example 2, the difference being: Figure 4 The cable tie 7 shown has several locking teeth 10 fixedly installed on the outer walls of both ends, and several locking teeth 9 fixedly installed on the inner walls of each channel 11. Each inner wall of each channel 11 away from the locking teeth 9 has a pressing block 37 fixedly installed. Each pressing block 37 has a guide slope at its end, and the guiding directions of adjacent pressing blocks 37 are opposite. The pressing block 37 can make the locking teeth 10 of the cable tie 7 engage with the locking teeth 9 on the inner wall of the channel 11.

[0030] When the cable tie 7 is inserted into the lower channel 11, the locking teeth 9 in the lower channel 11 engage with the locking teeth 10 of the cable tie 7, thereby preventing the fixing seat 6 and the cable tie 7 from retracting when the cable tie 7 is inserted into the upper channel 11. This prevents the fixing seat 6 from squeezing the aerogel felt 2 unevenly due to the cable tie 7 becoming loose. At the same time, the clamping block 37 in the channel 11 can keep the cable tie 7 straight in the channel 11, ensuring the stable transmission of the tightening force of the cable tie 7. This prevents the cable tie 7 from bending in the channel 11 of the thickness fixing part 4, which would cause a gap between the reinforcing mesh 3 and the aerogel felt 2, resulting in the aerogel felt 2 shifting.

[0031] Example 4 Example 4 is substantially the same as example 3, the difference is that as shown in Figure 5 It also includes a number of fixed components connecting the air condensation felt insulation structure and the wall, the fixed components include mounting block 12 and insertion block 13, the mounting block 12 is fixedly installed on the upper end of the wall by welding or expansion screws, as shown in Figure 6 The insertion slot 14 is opened in the mounting block 12, the insertion block 13 is fixedly installed on the outer wall of the wrapping layer 1, the lower end of the insertion block 13 can be inserted into the insertion slot 14, the right end of the mounting block 12 is provided with a sliding slot 15 in communication with the insertion slot 14, the sliding slot 15 is provided with an abutting piece, the abutting piece includes a support rod 16, an abutting block 17, a lifting block 18 and two first wedge blocks 19 and second wedge blocks 20, the support rod 16 is fixedly installed on the right wall of the sliding slot 15, the right end of the abutting block 17 is provided with a reset cavity 21, the reset cavity 21 is cylindrical, the left end of the support rod 16 penetrates the abutting block 17 and extends into the reset cavity 21, the left end of the support rod 16 is fixedly installed with a limiting block 22, the limiting block 22 is cylindrical matched with the reset cavity 21, the outer wall of the support rod 16 is sleeved with a first spring 23, and the left end of the first spring 23 is fixedly connected with the limiting block 22, the right end of the first spring 23 is fixedly connected with the inner wall of the reset cavity 21, two first wedge blocks 19 are symmetrically fixedly installed on the right end of the abutting block 17, the upper end of the mounting block 12 is provided with a lifting slot 24 in communication with the sliding slot 15, the front and rear inner walls of the lifting slot 24 are symmetrically provided with sliding grooves 25, the lifting block 18 is slidingly installed between the two sliding grooves 25, two second wedge blocks 20 are symmetrically fixedly installed on the lower end of the lifting block 18, and the second wedge blocks 20 abut against the first wedge blocks 19, when the second wedge blocks 20 move downward, the first wedge blocks 19 push the abutting block 17 to abut against the insertion block 13, the right end of the first wedge blocks 19 is fixedly installed with a guide block 26, the guide block 26 is semicylindrical, the left end of the second wedge blocks 20 is provided with a guide slot 27 matched with the guide block 26, after the guide block 26 is embedded in the guide slot 27, the relative deviation of the first wedge blocks 19 and the second wedge blocks 20 in horizontal and vertical directions can be limited, and it is ensured that the first wedge blocks 19 and the second wedge blocks 20 only relatively slide along the inclined surface direction.

[0032] As shown in Figure 7The insertion block 13 is provided with a trigger groove 28, and a trigger piece is arranged in the trigger groove 28, which can push the insertion block 13, so that the insertion block 13 is tightly fitted with the inner wall of the insertion groove 14. The trigger piece comprises a connecting plate 29, a trigger plate 30 and a plug 31. The connecting plate 29 is slidingly installed in the trigger groove 28, and a plurality of second springs 32 are fixedly installed between the upper end of the connecting plate 29 and the upper wall of the trigger groove 28. A through groove 33 is arranged in the lower end of the insertion block 13 and is communicated with the trigger groove 28. The trigger plate 30 is fixedly installed at the lower end of the connecting plate 29 and can extend out of the through groove 33 and abut against the lifting block 18. A locking groove 34 is arranged in the lower end of the insertion block 13 and is communicated with the through groove 33. The plug 31 is slidingly installed in the locking groove 34. A trapezoidal block 35 is fixedly installed at the lower side of the right end of the plug 31. A special-shaped groove 36 is arranged in the upper end of the mounting block 12 and is matched with the trapezoidal block 35. The inclined surface of the trapezoidal block 35 is tangent to the inclined surface of the special-shaped groove 36.

[0033] In order to improve the installation efficiency of the heat preservation structure, the prior art usually adopts an insertion type installation method to fixedly install the heat preservation structure on the wall. Compared with the bolt fixing method, the installation efficiency is greatly improved. However, the insertion type installation method is prone to cause gaps between the clamping block and the clamping groove, resulting in shaking of the heat preservation structure when installed on the wall, and unevenness of the heat preservation structure of the whole wall due to the installation gap. In the present scheme, when the insertion block 13 is inserted into the insertion groove 14 of the mounting block 12, the trapezoidal block 35 at the lower end of the plug 31 moves downward with the insertion block 13 and contacts the inclined surface of the special-shaped groove 36. At this time, the plug 31 slides along the inclined surface of the special-shaped groove 36. When the insertion block 13 is completely inserted into the insertion groove 14, the plug 31 is separated from the trigger plate 30, so that the trigger plate 30 extends out of the through groove 33 and contacts the lifting block 18 under the action of the second springs 32, and the lifting block 18 slides downward along the lifting groove 24, so that the inclined surface of the second wedge-shaped block 20 presses the first wedge-shaped block 19, converts the driving force in the vertical direction into the thrust in the horizontal direction, and pushes the abutting block 17 to accurately extend into the insertion groove 14 and tightly abut against the insertion block 13, thereby eliminating the gap between the insertion block 13 and the insertion groove 14, greatly improving the connection strength between the heat preservation structure and the wall, and effectively preventing loosening or displacement caused by external force.

[0034] When the insertion block 13 is inserted into the insertion slot 14 of the mounting block 12, the trigger member interacts with the abutting member, so that the abutting member pushes the insertion block 13, and the insertion block 13 is tightly attached to the inner wall of the insertion slot 14, thereby eliminating the gap between the insertion block 13 and the insertion slot 14, greatly improving the connection strength between the heat preservation structure and the wall, effectively preventing loosening or displacement caused by external force, ensuring that the heat preservation structure is stably fixed on the wall for a long time, and when the insertion block 13 is attached to the inner wall of the insertion slot 14, the heat preservation structure is parallel to the wall surface, thereby avoiding the angle deviation of adjacent heat preservation structures and improving the flatness of the heat preservation structure during installation.
