[0024] In summary, the present invention mainly has the following beneficial effects:

[0025] The present invention discloses a low-energy building exterior wall insulation system, which adopts internal and external mixed insulation technology, affixes polyurethane panels on the inner side of the exterior wall, and affixes fiber reinforced cement panels on the inner side of the I-beam to enhance the thermal bridge breaking function of the exterior wall, thereby weakening the cold bridge effect caused by the steel structure. The exterior wall outer insulation layer adopts a rigid foam polyurethane panel, which effectively avoids the problems of cracking, hollowing, and falling off of the exterior insulation layer due to temperature changes and long-term use, and reduces the indoor "condensation" phenomenon. In addition, an empty chamber is formed on the inner side of the I-beam, and the low thermal conductivity of the air is used to reduce heat transfer. The outer side is filled with a rigid foam polyurethane panel to form a double-layer thickened insulation structure, thereby blocking the cold bridge effect caused by the high thermal conductivity of the steel structure. By arranging a self-adhesive waterproof vapor barrier film at the corner joint of the fiber reinforced cement panel, it is effectively prevented that indoor water vapor penetrates into the interior of the insulation layer, and the problem of moisture affecting the insulation effect or causing the roll material to bulge is avoided. Finally, the rigid foam polyurethane insulation board is fixed by thermal bridge anchor bolts. While ensuring the insulation board is fixed, it can effectively reduce the deformation and cracks of the building structure caused by temperature changes, earthquakes and other factors, thereby improving the overall stability and safety of the building.

[0026] The rigid polyurethane foam board design of the present invention has significant beneficial effects. By providing an internal cavity and a push plate mechanism for storing and releasing glue, precise control and uniform release of the glue are achieved. Specifically, the internal cavity is divided into two parts, and the release of the glue is controlled by the first push plate and the second push plate, respectively, to ensure that the glue can flow out evenly through the first release port and the second release port to form a stable adhesive layer. This design effectively solves the problem of uneven glue distribution in traditional insulation systems, enhances the bonding strength between the rigid polyurethane foam board and the base wall or I-beam, thereby improving the stability and construction quality of the overall insulation system.

[0027] In the present invention, the synergistic effect of the first push plate and the second push plate ensures uniform distribution of the glue, avoiding the problem of loose bonding. The setting of the release component ensures that the glue flows out at the right time to form a uniform adhesive layer, further improving the stability of the insulation system. Through the automated glue release system, the reliance on manual operation is reduced, the construction efficiency is improved, and the labor intensity is reduced. At the same time, the precise control and consistency of the glue are ensured, and the quality problems caused by improper manual operation are reduced.

[0028] In addition, the setting of the connecting rod enables the first push plate and the second push plate to move in coordination to achieve precise release of glue. The design of the top rod provides additional stability, ensuring uniform release of glue during the installation of the thermal break anchor bolt. The setting of the baffle allows the incompletely released glue to flow from the connection groove to the wedge-shaped guide plate and further released through the third release port, ensuring that all glue is fully utilized. This design not only improves the release efficiency of glue, but also improves the construction quality, reduces the risk of insulation board falling off, and improves the overall performance and reliability of the insulation system.

[0047] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0048] refer to Figure 1-Figure 12 A low-energy building exterior wall insulation system comprises a base wall 100 and an I-beam 101, wherein a mortar layer 102 and a polyurethane board 103 are sequentially arranged on the inner surface of the base wall 100, and the mortar layer 102 is used to firmly bond the polyurethane board 103 to the self-insulating block base wall 100;

[0049] The outer surface of the base wall 100 is provided with a rigid foam polyurethane board 104, a plastering mortar layer 105 and a finishing layer 106 in sequence, and the rigid foam polyurethane board 104 is bonded to the base wall 100 through a full-bonded adhesive layer 107;

[0050] A layer of alkali-resistant glass fiber mesh 108 is pressed into the plastering mortar layer 105 to prevent the exterior wall insulation structure from cracking, hollowing or falling off during long-term use in hot summer and cold winter areas;

[0051] A plurality of thermal break anchor bolts 109 are arranged on the outer surface of the base wall 100. The thermal break anchor bolts 109 penetrate the rigid foam polyurethane board 104 and the adhesive layer 107 and are fixed on the base wall 100 to provide stability of the thermal insulation structure and reduce the transfer of heat energy.

[0052] An airtight layer 110 is provided between the outer surface of the mortar layer 102 and the polyurethane plate 103;

[0053] This structure can effectively improve the thermal insulation performance of the building. The mortar layer 102 can ensure the firm bonding of the polyurethane board 103 and the base wall 100, and the combination of the rigid foam polyurethane board 104 and the plastering mortar layer 105 can provide a long-term thermal insulation effect while preventing the quality problems of the exterior wall due to climatic conditions. The thermal bridge anchor bolts 109 further enhance the overall stability of the structure, reduce the thermal bridge effect, and thus reduce the loss of heat energy.

[0054] The rigid polyurethane foam board 104 includes a cavity 200 opened in the rigid polyurethane foam board 104, and glue is provided in the cavity 200. A first push plate 201 and a second push plate 202 are provided in the cavity 200. The glue is divided into two parts, one part of the glue is located on one side of the first push plate 201, and the other part of the glue is located on the top of the second push plate 202. The second push plate 202 is located on the top of the first push plate 201. A plurality of first release ports 203 and second release ports 204 are opened on one side of the rigid polyurethane foam board 104, which are connected to the cavity 200. A moving component is provided between the first push plate 201 and the second push plate 202, which is used to move the position of the second push plate 202 when the first push plate 201 moves. The first push plate 201 moves horizontally, and the second push plate 202 moves longitudinally. A releasing component is provided between the cavity 200 and the first release port 203 and the second release port 204, which is used to release glue when the first push plate 201 and the second push plate 202 move. After the glue is released, an adhesive layer 107 is formed. The first push plate 201 can move when the thermal break anchor bolt 109 is connected to the base wall 100;

[0055] An internal cavity 200 for storing and releasing glue is provided. The cavity 200 is divided into two parts, and the release of glue is controlled by a first push plate 201 and a second push plate 202 respectively. The first push plate 201 moves laterally, driving the glue on one side thereof to flow toward the first release port 203; at the same time, the second push plate 202 moves longitudinally under the action of the moving component, guiding the glue on its top to the second release port 204. The glue flows out from the release port when the push plate moves under the control of the release component, forming a uniform adhesive layer 107. The adhesive layer 107 is used to firmly adhere the rigid foam polyurethane board 104 to the base wall 100 or the I-beam 101. In addition, the first push plate 201 can move when the thermal bridge anchor bolt 109 is connected to the base wall 100, ensuring that the glue can be evenly released and form a strong bond during the anchoring process. Through the structural design of the rigid foam polyurethane board 104 of the present invention, the precise control and release of glue in the building exterior wall insulation system is achieved, and the bonding strength between the insulation board and the base wall 100 or the I-beam 101 is effectively improved. The synergistic effect of the first push plate 201 and the second push plate 202 ensures the uniform distribution of glue and avoids the problem of loose bonding. In addition, the setting of the release component ensures that the glue flows out at the right time, forming a uniform adhesive layer 107, which improves the stability of the entire insulation system. Through this design, common problems such as the shedding and hollowing of the insulation layer can be effectively reduced, while enhancing the overall performance and durability of the exterior wall insulation system.

[0056] As a further solution of the present invention, the number of the thermal break anchor bolts 109 is determined by calculating the wind load of the external insulation system, and there are no less than six and no more than fourteen anchor points per square meter, and the anchor points are regularly distributed;

[0057] The reliability and stability of the external insulation system under different wind load conditions can be ensured by the reasonable distribution and number of thermal break anchor bolts 109. This design ensures that the insulation layer will not loosen or fall off due to lack of anchor points under strong wind conditions, thereby extending the service life of the building.

[0058] As a further solution of the present invention, a fiber reinforced cement board 300 and a mortar layer 102 are sequentially arranged on the inner side of the I-beam 101, and a rigid foam polyurethane board 104 is also filled on the outer side of the I-beam 101, and the rigid foam polyurethane board 104 is double-layered;

[0059] This design enables the I-beam 101 to obtain good thermal insulation effect inside the structure, while the combination of the fiber reinforced cement board 300 and the mortar layer 102 ensures the structural strength and fire resistance of the building. The double-layer design of the rigid foam polyurethane board 104 further improves the thermal insulation performance, making the building more energy-efficient.

[0060] As a further solution of the present invention, a self-adhesive waterproof vapor barrier film 301 is provided at the corner of the fiber reinforced cement board 300, and the overlap length of the waterproof vapor barrier film is 50 mm, which is used to prevent indoor water vapor from penetrating into the insulation layer;

[0061] In the present invention, the self-adhesive waterproof vapor barrier film 301 is arranged at the corner of the fiber reinforced cement board 300, which effectively prevents water vapor from penetrating into the insulation layer through the roof panel, thereby preventing the degradation of insulation performance due to moisture. The design of the overlap length of 50 mm ensures the sealing of the joint and improves the overall effect of the insulation layer.

[0062] As a further solution of the present invention, when the building exterior wall is decorated with a dry-hanging curtain wall, the curtain wall keel 302 passes through the rigid foam polyurethane insulation layer and is fixed on the web of the I-beam 101. The connection between the curtain wall keel 302 and the I-beam 101 is padded with a high-strength polyurethane insulation pad 303 to disconnect the thermal bridge;

[0063] The high-strength polyurethane heat-insulating pad 303 can form an effective heat-insulating layer between the curtain wall keel 302 and the I-beam 101, disconnect the heat bridge, and avoid the heat loss caused by the heat bridge effect. At the same time, the reasonable fixation of the curtain wall keel 302 ensures the overall stability and durability of the dry-hanging curtain wall system.

[0064] As a further solution of the present invention, an anchoring opening 400 is provided on one side of the rigid polyurethane foam board 104, and penetrates the rigid polyurethane foam board 104. There are multiple anchoring openings 400, and the thermal bridge anchor bolt 109 is inserted into the anchoring opening 400. A glue groove 401 is provided between every two adjacent anchoring openings 400, and is communicated with the first release opening 203 and the second release opening 204.

[0065] In the present invention, a plurality of anchor openings 400 are provided on one side of the rigid foam polyurethane board 104, and these anchor openings 400 run through the entire rigid foam polyurethane board 104, allowing the thermal bridge anchor bolts 109 to be inserted therein. The glue tank 401 is used to store and distribute glue. When the rigid foam polyurethane board 104 is connected to the base wall 100 or the I-beam 101, the glue flows out from the first release port 203 and the second release port 204, and is distributed around the anchor opening 400 through the glue tank 401 to form a uniform adhesive layer 107. The thermal break anchor bolt 109 is fixed to the base wall 100 or the I-beam 101 through the anchoring port 400, and glue is filled between the anchoring port 400 and the glue tank 401, thereby enhancing the bonding strength and stability. This design can enhance the bonding strength, improve the stability of the insulation board and the foundation structure, and ensure the uniform distribution of glue, thereby improving the construction effect, avoiding the problem of insulation board falling off or displacement, and improving the overall performance and construction quality of the insulation system.

[0066] As a further solution of the present invention, the release component includes a fixing frame 402 connected to the first release port 203 and the second release port 204, the fixing frame 402 is provided with a needle 403, and two capsules 404 are provided in the cavity 200, the capsules 404 are made of a tough plastic film, and glue is filled in the capsules 404, one of the capsules 404 is located on one side of the first push plate 201, and the other capsule 404 is located on the top of the second push plate 202;

[0067] In the present invention, when the first push plate 201 moves, the second push plate 202 can be moved by the moving parts. During the movement of the two push plates, pressure can be applied to the bladder 404 to expand the bladder 404. A part of the bladder 404 will protrude from the first release port 203 and the second release port 204 due to the characteristics of the material of the bladder 404 itself. The needle 403 on the fixing frame 402 will pierce the bladder 404, and the glue with pressure in the bladder 404 can gush out. The release ports are evenly distributed in the glue groove. In this way, the glue can be effectively released and form a uniform adhesive layer 107, ensuring that the rigid foam polyurethane board 104 is firmly bonded to the base structure. This design not only enhances the bonding strength between the insulation board and the base wall 100 or the I-beam 101, reduces the risk of the insulation board falling off, but also improves the uniformity of glue distribution, thereby improving the stability and application of the overall insulation system. The quality of work is improved. The release of glue no longer relies on manual operation, but is automatically completed by mechanical means, ensuring that the glue forms a uniform adhesive layer 107 between the rigid foam polyurethane board 104 and the base structure. The automated glue release system can ensure that the glue is evenly distributed on the entire contact surface, avoiding the problem of uneven coating that may occur during manual gluing, reducing the cumbersome steps of manual gluing, and reducing dependence on manual operation, thereby improving construction efficiency and reducing labor intensity. The automated release system ensures precise control and consistency of the glue, reducing quality problems caused by improper manual operation, such as too much or too little glue. By mechanized glue release, construction errors caused by human factors are reduced, and the reliability and accuracy of the overall construction are improved. The automatic release system can quickly and evenly distribute the glue, speeding up the construction progress, and is more efficient than manual gluing.

[0068] As a further solution of the present invention, the moving component includes a connecting rod 500 rotatably connected to the top of the first push plate 201, the top of the connecting rod 500 is rotatably connected to the second push plate 202, and a plurality of top rods 501 are connected to one side of the first push plate 201, and the top rods 501 extend into the anchoring opening 400;

[0069] In the present invention, the connection rod 500 is arranged so that when the first push plate 201 moves laterally, the connection rod 500 transmits this lateral movement to the second push plate 202 by rotating, so that the second push plate 202 moves longitudinally accordingly. In this way, the movement of the first push plate 201 not only promotes the release of the glue on one side thereof, but also enables the second push plate 202 to move in a predetermined direction, thereby ensuring the uniform distribution and effective release of the glue. The design of the moving component can accurately control the release process of the glue. Through the rotation connection of the connection rod 500, the coordinated movement between the first push plate 201 and the second push plate 202 can be achieved, ensuring that the glue can be evenly distributed throughout the process. The provision of the connecting rod 500 improves the operating efficiency of the system, makes the release of glue more uniform and effective, thereby enhancing the bonding strength between the rigid foam polyurethane board 104 and the basic structure, improving the construction quality, reducing the risk of the insulation board falling off, and improving the stability and reliability of the overall insulation system. Among them, the provided top rod 501 extends into the anchoring port 400. After the thermal bridge breaking anchor 109 is inserted into a central anchoring port 400, the thermal bridge breaking anchor 109 can touch the top rod 501, so that the purpose of moving the top rod 501 and the first push plate 201 can be achieved. The design of the top rod 501 not only provides additional stability and support, but also ensures that during the installation of the thermal bridge breaking anchor 109, the first push plate 201 can effectively move and release the glue evenly.

[0070] As a further solution of the present invention, a third release port 502 corresponding to the capsule 404 on the top of the second push plate 202 is provided in the glue tank 401;

[0071] The second push plate 202 includes a first plate 503 and a second plate 504, the connecting rod 500 is rotatably connected to the bottom of the second plate 504, a connecting plate 505 is connected between the first plate 503 and the second plate 504, a wedge-shaped guide plate 506 is connected to one side of the connecting plate 505, a connecting groove 511 is opened on one side of the first plate 503, and a baffle 507 is slidably connected in the connecting groove 511;

[0072] In the present invention, when the second push plate 202 moves upward, the first plate 503 and the second plate 504 push the capsule 404 to rupture it, and release the glue from the second release port 204. However, since the puncture needle 403 punctures the middle of the capsule 404, the second plate 504 may not be able to completely squeeze the capsule 404 after moving to the extreme position, resulting in a portion of glue remaining in the capsule 404. In order to deal with this problem, a baffle 507 is provided. When the second plate 504 moves to the preset position, the baffle 507 also moves therewith, so that the residual glue can flow from the connecting groove 511 to the wedge-shaped guide plate 506, and finally flow out through the third release port 502. In this way, it can be ensured that all glue can be fully released and cover the required area. This design effectively solves the problem that the residual glue in the capsule 404 cannot be completely released through the synergy between the second push plate 202 and the first push plate 201, and the setting of the baffle 507 and the wedge-shaped guide plate 506. The movement of the first plate 503 and the second plate 504 can squeeze the capsule 404, ensuring that most of the glue is released from the second release port 204. For the glue that cannot be completely released, the setting of the baffle 507 allows the glue to flow from the connecting groove 511 to the wedge-shaped guide plate 506, and further released through the third release port 502. This technology not only improves the release efficiency of the glue and ensures the uniform distribution of the glue, but also reduces the problem of insufficient bonding caused by residual glue, and improves the bonding strength and construction quality of the thermal insulation layer.

[0073] As a further solution of the present invention, an extrusion groove 508 communicating with the connecting groove 511 is provided on one side of the first plate 503, a spring 509 is connected between the baffle 507 and the connecting groove 511, a traction rope 510 is connected to one side of the connecting rod 500, and one end of the traction rope 510 extends into the connecting groove 511 and is connected to the baffle 507;

[0074] In the present invention, during the process of the first push plate 201 pressing the capsule 404, the capsule 404 will deform and expand, and the glue in the capsule 404 will enter the extrusion groove 508. As the first plate 503 rises, the capsule 404 will be torn. This deformation causes the bottom of the capsule 404 to further rupture after being punctured by the needle 403, so that the glue flows from the extrusion groove 508 and the connecting groove 511 to the wedge-shaped guide plate 506, and is finally released through the third release port 502. The design of the extrusion groove 508 enables the glue at the bottom to flow to the connecting groove 511 more effectively when the capsule 404 is deformed, ensuring that the glue can be fully released and cover all areas that need to be bonded. The needle 403 first punctures the middle part of the capsule 404, and this behavior triggers the initial release of the glue, so that the glue can flow out from the main part of the capsule 404. At this time, the glue will begin to flow out from the middle of the capsule 404, but the glue at the bottom will still remain in the capsule 404. After the needle 403 punctures, the bottom of the capsule 404 will further rupture due to the continuous application of pressure and the deformation of the capsule 404. This process ensures that the glue at the bottom of the capsule 404 can also be released. This step-by-step release method helps to evenly distribute the glue in the required area and avoids the unevenness caused by the concentrated release of the glue. By allowing the bottom of the capsule 404 to rupture after the needle 403 punctures, it can be ensured that the glue can flow out from all parts of the capsule 404. In this way, the contact surface can be more fully covered and the bonding effect can be improved.
