Description

Technical Field

[0001] This invention relates to the field of exterior wall insulation systems, and particularly to an energy-saving exterior wall insulation system for buildings. Background Technology

[0002] Installing insulation boards on the exterior walls of buildings improves their thermal insulation performance, reduces the rate of heat exchange between the interior and exterior spaces, and consequently reduces energy consumption for heating or air conditioning within the building, thus achieving energy conservation and emission reduction.

[0003] In existing technologies, insulation boards are usually directly fixed to the exterior wall of a building with multiple screws. When an insulation board is damaged or warped, affecting its aesthetic performance, workers can only unscrew all the screws fixing the insulation board, replace it with a new insulation board, and then retighten the screws. This operation is quite cumbersome. Therefore, it is necessary to improve the installation method of insulation boards in related technologies to increase the efficiency of workers in installing and replacing insulation boards. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an energy-saving thermal insulation system for building exterior walls.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an energy-saving thermal insulation system for building exterior walls, comprising an installation plate fixed to the surface of a wall and a vacuum insulation panel disposed on the side of the installation plate away from the wall. Multiple installation plates are provided, and the number of vacuum insulation panels is equal to the number of installation plates, with their positions corresponding one-to-one. The edges of the multiple vacuum insulation panels are abutted against each other to form an insulation board structure parallel to the wall surface. Grooves are provided at the four corners of each vacuum insulation panel. A group of first elastic blocks is fixed to the sidewall of the installation plate near the vacuum insulation panel. A group of second elastic blocks is fixed to the sidewall of the vacuum insulation panel near the wall. A first V-shaped portion is provided on the side of the group of first elastic blocks that are close to each other, and a second V-shaped portion is provided on the side of the group of second elastic blocks that are far from each other. The inclined surface of the second V-shaped portion abuts against the inclined surface of the first V-shaped portion.

[0006] By adopting the above technical solution, both the first and second elastic clips are made of materials with a certain elastic deformation capacity, such as plastic. The first V-shaped part and the second V-shaped part cooperate to facilitate the installation and removal of the vacuum insulation panel on the mounting plate. When replacing a damaged vacuum insulation panel, the worker can remove it by pulling the panel outward through the groove at the corner of the damaged panel. When installing the vacuum insulation panel, simply push the panel towards the side closer to the wall, causing the two first elastic clips to deform towards the side away from each other, and the two second elastic clips to deform towards the side closer to each other. After installation, the first and second elastic clips return to their original positions, and the inclined surface of the second V-shaped part abuts against the inclined surface of the first V-shaped part, ensuring the normal use of the building's external wall energy-saving insulation system.

[0007] Furthermore, springs are fixed to the sides of the two second elastic blocks that are close to each other, and the springs are located on the side of the second elastic blocks away from the vacuum insulation plate.

[0008] By adopting the above technical solution, the spring has good elastic properties and exerts a pushing force on the two second elastic blocks to move away from each other, so that the inclined surface of the second V-shaped part abuts against the inclined surface of the first V-shaped part, which helps to enhance the stability of the vacuum insulation panel installed on the mounting plate.

[0009] Furthermore, an outer annular rubber sleeve is fixed on the side wall of the vacuum insulation panel near the wall. The first elastic block and the second elastic block are both located inside the outer annular rubber sleeve. Four rubber insulation plates are fixed on the outer wall of the outer annular rubber sleeve, which are evenly distributed about the axis of the outer annular rubber sleeve. The end of the rubber insulation plate away from the outer annular rubber sleeve is in contact with the corresponding rubber insulation plate of the other vacuum insulation panel.

[0010] By adopting the above technical solution, the outer ring rubber sleeve works in conjunction with the four rubber insulation plates around it to isolate adjacent vacuum insulation plates from each other, reducing the probability of heat convection in the gaps between adjacent vacuum insulation plates and improving the thermal insulation effect of the building exterior wall energy-saving insulation system.

[0011] Furthermore, an inner annular rubber sleeve is fixed on the side wall of the mounting plate away from the wall. The outer wall of the inner annular rubber sleeve is in contact with the inner wall of the outer annular rubber sleeve, and the first elastic block and the second elastic block are both located inside the inner annular rubber sleeve.

[0012] By adopting the above technical solution and selecting an inner annular rubber sleeve with appropriate hardness, the inner annular rubber sleeve provides good support for the outer annular rubber sleeve, thereby enhancing the stability of the vacuum insulation panel installed on the mounting plate.

[0013] Furthermore, the groove is a 1 / 4 arc-shaped groove, and a begonia corner communicating with the groove is provided at the intersection between the side wall of the vacuum insulation panel away from the wall and the side wall of the periphery of the vacuum insulation panel. A gap connection layer is provided in the groove and the begonia corner of the adjacent vacuum insulation panels.

[0014] By adopting the above technical solution, the gap connection layer is set so that the gap between adjacent vacuum insulation panels is fully filled, reducing the probability of heat convection between adjacent vacuum insulation panels and further improving the thermal insulation effect of the building exterior wall energy-saving insulation system.

[0015] Furthermore, the components of the gap bonding layer include the following raw materials in parts by weight: 30-40 parts epoxy resin, 2-6 parts curing agent, 10-20 parts silicate cement, 3-9 parts carbide slag, 14-22 parts activator, 8-14 parts interface agent, and 40-100 parts water.

[0016] Furthermore, the activator is sodium sulfate.

[0017] Furthermore, the interface agent is silica fume.

[0018] By adopting the above technical solution, sodium sulfate is selected as the activator. Under the action of sodium sulfate, the phosphorus slag powder and carbide slag are continuously hydrated, and the internal structure of the mixture system is continuously filled and compacted by the hydration products, thereby continuously improving the various durability properties of the mixture system. The main components of carbide slag are calcium hydroxide (Ca(OH)2) and aluminum hydroxide (Al(OH)3). The phosphorus slag powder is combined with silica fume and reacts with Ca(OH)2 enriched on the interface to generate CSH gel, thereby reducing the porosity of carbide slag. The CSH gel has better brittleness than Ca(OH)2. CSH is beneficial to reducing the brittleness coefficient and fully improving the crack resistance of the mixture system. In addition, it improves the durability and crack resistance of the joint bonding layer, which is conducive to extending the service life of the building's external wall energy-saving insulation system.

[0019] Furthermore, the preparation method of the constituent raw materials of the gap connection layer includes the following steps: S1. Weigh epoxy resin, silicate cement, carbide slag, activator, interface agent and water according to the proportion, and stir with an electromagnetic stirring device at a speed of 500r / min for 20-30min to obtain the mixture system. S2. Weigh the curing agent according to the ratio and add it to the mixture system obtained in S1. Place it in an ultrasonic dispersion device and disperse it for 70-90 minutes under the conditions of ultrasonic frequency 40-50kHz and power 200-240W. This is the result.

[0020] Furthermore, the raw materials constituting the gap connection layer are doped with polypropylene fibers / glass fibers during the coating process in the grooves and begonia corners.

[0021] By adopting the above technical solution, the polypropylene fiber / glass fiber has a fine diameter and moderate length. After stirring, it is evenly dispersed and distributed in a two-dimensional random pattern in silica fume. The fiber is in a curved state, which increases the bonding strength between the fiber and silica fume and other mixture systems, reduces the capillary channels formed by water overflow in silica fume, delays the generation of cracks and controls the development of cracks, and further improves the crack resistance and impermeability of the joint bonding layer.

[0022] In summary, the present invention has the following beneficial effects: 1. In this application, the spring has good elastic properties and exerts a pushing force on the two second elastic blocks to move away from each other, so that the inclined surface of the second V-shaped part abuts against the inclined surface of the first V-shaped part, which is beneficial to enhance the stability of the vacuum insulation panel installed on the mounting plate. 2. In this application, the outer annular rubber sleeve works in conjunction with the four rubber insulation plates on its periphery to isolate adjacent vacuum insulation plates from each other, reducing the probability of heat convection in the gaps between adjacent vacuum insulation plates and improving the thermal insulation effect of the building exterior wall energy-saving insulation system. 3. In this application, sodium sulfate is selected as the activator. Under the action of sodium sulfate, the phosphorus slag powder and carbide slag continuously hydrate, and the internal structure of the mixture system is continuously filled and compacted by the hydration products, thus continuously improving the various durability properties of the mixture system. The main components of carbide slag are calcium hydroxide (Ca(OH)2) and aluminum hydroxide (Al(OH)3). The phosphorus slag powder, combined with silica fume, reacts with the Ca(OH)2 enriched at the interface to generate CSH gel, thereby reducing the porosity of the carbide slag. The CSH gel has better resilience than Ca(OH)2, and CSH is beneficial in reducing the brittleness coefficient, thus significantly improving... The crack resistance of the mixture system improves the durability and crack resistance of the joint bonding layer, which is beneficial to extending the service life of the building's exterior wall energy-saving insulation system; 4. In this application, the polypropylene fiber / glass fiber has a fine diameter and moderate length. After stirring, it is evenly dispersed and distributed in a two-dimensional random pattern in silica fume. The fiber is in a bent state, which increases the bonding strength between the fiber and silica fume and other mixture systems, reduces the capillary channels formed by water overflow in silica fume, delays the generation of cracks and controls the development of cracks, and further improves the crack resistance and impermeability of the joint bonding layer.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] like Figure 1-4 As shown in the embodiment, this application discloses an energy-saving thermal insulation system for building exterior walls, including an mounting plate 1 and a vacuum insulation panel 2. The mounting plate 1 is fixed to the surface of a wall 3. Specifically, a slanted insert plate 11 is fixed to one side wall of the mounting plate 1, and a slanted slot 31 for inserting the slanted insert plate 11 is provided at the corresponding position on the side wall of the wall 3. To enhance the stability of the mounting plate 1 on the wall 3, a reinforcing screw 12 for fixing the mounting plate 1 to the wall 3 is provided through the mounting plate 1. In this embodiment, multiple mounting plates 1 are provided, adjacent mounting plates 1 are attached to each other, and multiple mounting plates 1 are attached to the side wall of the wall 3.

[0026] The size of the vacuum insulation panel 2 is the same as that of the mounting plate 1. The number of vacuum insulation panels 2 is the same as the number of mounting plates 1 and their positions correspond one-to-one. Multiple vacuum insulation panels 2 are joined together at their edges to form an insulation board structure parallel to the surface of the wall 3. A groove 21 is provided at each of the four corners of the vacuum insulation panel 2. The groove 21 is a 1 / 4 arc-shaped groove. A corner 22 connected to the groove 21 is provided at the intersection between the side wall of the vacuum insulation panel 2 away from the wall 3 and the side wall of the vacuum insulation panel 2. A gap connection layer 4 is provided in the groove 21 and corner 22 of adjacent vacuum insulation panels 2.

[0027] In this embodiment, a group of first elastic blocks 13 are fixed on the side wall of the mounting plate 1 near the vacuum insulation board 2, and a group of second elastic blocks 23 are fixed on the side wall of the vacuum insulation board 2 near the wall 3. A first V-shaped portion 131 is provided on the side of the group of first elastic blocks 13 that are close to each other, and a second V-shaped portion 231 is provided on the side of the group of second elastic blocks 23 that are far from each other. The inclined surface of the second V-shaped portion 231 abuts against the inclined surface of the first V-shaped portion 131. Both the first elastic locking block 13 and the second elastic locking block 23 are made of materials with a certain elastic deformation capacity, such as plastic. The first V-shaped part 131 and the second V-shaped part 231 cooperate to facilitate the installation and removal of the vacuum insulation panel 2 on the mounting plate 1. This allows workers to pass through the groove 21 at the corner of the damaged vacuum insulation panel 2 when replacing it. (When removing the corresponding vacuum insulation panel 2, the gap connecting layer 4 in the groove 21 at any two opposite corners of the vacuum insulation panel 2 must first be broken to allow workers to pass through the groove 21.) The vacuum insulation panel 2 can be disassembled by pulling it outwards (applying force to it). When installing the vacuum insulation panel 2, simply push it towards the side closer to the wall 3, causing the two first elastic blocks 13 to deform towards the side away from each other, and the two second elastic blocks 23 to deform towards the side closer to each other. After installation, the first elastic blocks 13 and the second elastic blocks 23 are reset, and the inclined surface of the second V-shaped part 231 abuts against the inclined surface of the first V-shaped part 131, ensuring the normal use of the building's exterior wall energy-saving insulation system.

[0028] To reduce air convection between adjacent vacuum insulation panels 2, an outer annular rubber sleeve 5 is fixed to the side wall of the vacuum insulation panel 2 closest to the wall 3. The first elastic locking block 13 and the second elastic locking block 23 are both located inside the outer annular rubber sleeve 5. Four rubber insulation plates 51, evenly distributed about the axis of the outer annular rubber sleeve 5, are fixed to the outer wall of the outer annular rubber sleeve 5. The ends of the rubber insulation plates 51 furthest from the outer annular rubber sleeve 5 are in contact with the corresponding rubber insulation plates 51 of the other vacuum insulation panels 2. The outer annular rubber sleeve 5, in conjunction with the four rubber insulation plates 51 around it, isolates adjacent vacuum insulation panels 2 from each other, reducing the probability of heat convection occurring in the gaps between adjacent vacuum insulation panels 2 and improving the thermal insulation effect of the building's exterior wall energy-saving insulation system. To enhance the stability of the vacuum insulation panel 2 during use, springs 6 are fixed to the sides of the two second elastic blocks 23 that are close to each other. The springs 6 are located on the side of the second elastic blocks 23 away from the vacuum insulation panel 2. Furthermore, an inner annular rubber sleeve 7 is fixed to the side wall of the mounting plate 1 away from the wall 3. The outer wall of the inner annular rubber sleeve 7 fits against the inner wall of the outer annular rubber sleeve 5. Both the first elastic block 13 and the second elastic block 23 are located within the inner annular rubber sleeve 7. By selecting an inner annular rubber sleeve 7 with appropriate hardness, it provides good support for the outer annular rubber sleeve 5, enhancing the stability of the vacuum insulation panel 2 installed on the mounting plate 1.

[0029] The operating principle of the building exterior wall energy-saving insulation system in this embodiment is as follows: The first elastic clip 13 and the second elastic clip 23 are both made of materials with a certain elastic deformation capacity, such as plastic. The first V-shaped part 131 and the second V-shaped part 231 cooperate to facilitate the installation and removal of the vacuum insulation panel 2 on the mounting plate 1. This allows workers to easily replace damaged vacuum insulation panels 2 by using the grooves 21 at the corners of the damaged vacuum insulation panels 2 (when removing the corresponding vacuum insulation panel 2, the gap connecting layer 4 in the grooves 21 at any two opposite corners of the vacuum insulation panel 2 must first be destroyed). To facilitate disassembly, workers can apply force to the vacuum insulation panel 2 through the groove 21 and pull it outward. When installing the vacuum insulation panel 2, simply push the vacuum insulation panel 2 toward the side closer to the wall 3, causing the two first elastic blocks 13 to deform toward the side away from each other, and the two second elastic blocks 23 to deform toward the side closer to each other. After installation, the first elastic blocks 13 and the second elastic blocks 23 are reset, and the inclined surface of the second V-shaped part 231 abuts against the inclined surface of the first V-shaped part 131, ensuring the normal use of the building's exterior wall energy-saving insulation system.

[0030] This embodiment also discloses that the components of the gap connection layer 4 include the following raw materials in parts by weight: 30-40 parts epoxy resin, 2-6 parts curing agent, 10-20 parts silicate cement, 3-9 parts carbide slag, 14-22 parts activator, 8-14 parts interface agent and 40-100 parts water.

[0031] The activator is sodium sulfate, the interface agent is silica fume, and the preparation method of the raw materials constituting the gap connection layer 4 includes the following steps: S1. Weigh epoxy resin, silicate cement, carbide slag, activator, interface agent and water according to the proportion, and stir with an electromagnetic stirring device at a speed of 500r / min for 20-30min to obtain the mixture system. S2. Weigh the curing agent according to the ratio and add it to the mixture system obtained in S1. Place it in an ultrasonic dispersion device and disperse it for 70-90 minutes under the conditions of ultrasonic frequency 40-50kHz and power 200-240W. This is the result.

[0032] Sodium sulfate is selected as the activator. Under the action of sodium sulfate, the phosphorus slag powder and carbide slag continuously hydrate, and the internal structure of the mixture system is continuously filled and compacted by the hydration products, thereby continuously improving the various durability properties of the mixture system. The main components of carbide slag are calcium hydroxide (Ca(OH)2) and aluminum hydroxide (Al(OH)3). The phosphorus slag powder is combined with silica fume and reacts with Ca(OH)2 enriched on the interface to generate CSH gel, thereby reducing the porosity of carbide slag. The CSH gel has better brittleness than Ca(OH)2. CSH is beneficial to reducing the brittleness coefficient and significantly improving the crack resistance of the mixture system. In turn, it improves the durability and crack resistance of the joint bonding layer 4, which is conducive to extending the service life of the building's external wall energy-saving insulation system.

[0033] To enhance the crack resistance of the joint bonding layer 4, polypropylene fibers / glass fibers are incorporated into the raw materials of the joint bonding layer 4 during the coating process within the groove 21 and the begonia corner 22. The polypropylene / glass fibers have a fine diameter and moderate length, and after stirring, they are evenly dispersed and distributed in a two-dimensional random pattern within the silica fume. The fibers are in a curved state, increasing the bonding strength between the fibers and the silica fume and other mixtures, reducing capillary channels formed by water overflow from the silica fume, delaying crack formation and controlling crack development, and further improving the crack resistance and impermeability of the joint bonding layer 4. The above description is merely a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
