Description

Technical Field

[0001] This application relates to building exterior walls, and more particularly to an energy-efficient building exterior wall structure with a ventilated and heat-insulating layer. Background Technology

[0002] In building energy conservation efforts, the heat loss of the external wall envelope is significant, and the wall itself is a major component of the external envelope. According to the principles of building engineering, developing external wall insulation technology has become an important aspect of achieving building energy conservation. It can not only save a lot of energy but also provide residents with a comfortable environment and bring many benefits.

[0003] A current patent (publication number: CN223003559U) discloses an energy-saving exterior wall insulation structure, including an outer shell. A second groove and a third groove are respectively formed on both sides of the outer shell. A sliding rod is fixedly connected inside the second groove, and a spring is provided outside the sliding rod. One end of the spring is fixedly connected to the inner wall of the second groove, and the other end of the spring is fixedly connected to a movable plate. A limit rod is fixedly connected to the side of the movable plate, and the movable plate and the sliding rod are slidably connected. A slider is fixedly connected to the top of the movable plate. A sliding groove is formed between the first wear-resistant layer and the top of the outer shell, and the slider is slidably connected within the sliding groove. A locking block is fixedly connected inside the third groove, and a limit groove is formed on the side of the locking block. By setting up the sliding groove, sliding rod, movable plate, limit rod, and spring, the exterior wall insulation structure can be easily installed and disassembled, solving the problem of low stability and easy detachment of traditional exterior wall insulation structures.

[0004] While the device in the aforementioned comparative document solves the problem of low stability and easy detachment of traditional external wall insulation structures, it requires the use of sliding rods, moving plates, limiting rods, springs, and other structures for connection, resulting in complex structures and high operating costs. In addition, the device lacks a ventilation structure, reducing ventilation and heat dissipation effects. To address these issues, an energy-saving building external wall structure with a ventilation and heat insulation layer is proposed. Utility Model Content

[0005] The purpose of this application is to provide an energy-saving building exterior wall structure with a ventilation and heat insulation layer, which has the advantages of ventilation function, simple structure and low cost, and solves the problems of complex structure, high cost of use, lack of ventilation structure and poor ventilation and heat dissipation effect of the comparative device.

[0006] The present application provides an energy-saving building exterior wall structure with ventilation and heat insulation layer, which adopts the following technical solution: including a base plate and a connecting component. The base plate has two through holes on the top two opposite sides and the bottom two opposite sides. A T-shaped connecting groove is provided between the two through holes. The connecting component is inserted into the T-shaped connecting groove of four adjacent base plates. The inner side of the T-shaped connecting groove is coated with a graphene lubricating coating. The substrate has a ventilation slot inside, a connecting U-shaped slot at the bottom of the ventilation slot, a U-shaped connecting block fixedly connected to the top of the ventilation slot, grooves on opposite sides inside the connecting U-shaped slot, protrusions fixedly connected to opposite sides of the U-shaped connecting block, and multiple guide fins on the inner side of the ventilation slot. By adopting the above technical solution, a passive ventilation system is formed by setting ventilation slots and guide fins. When air flows in the slots, the heat exchange area can be increased under the action of the guide fins, accelerating heat dissipation. In summer, the "chimney effect" can exhaust the hot air accumulated in the insulation layer. In winter, some ventilation openings can be closed to reduce cold air infiltration and balance the insulation requirements. By setting U-shaped connecting blocks, protrusions and grooves, modular and rapid assembly of the wall can be achieved. The plug-in design of U-shaped connecting blocks and grooves, combined with the locking of protrusions, can ensure splicing accuracy, reduce on-site welding or bolt fixing procedures, and is simple to operate and has low operating costs. By setting T-shaped connecting grooves and graphene lubricating coating, the connecting components are guided to be inserted accurately. The graphene coating reduces friction loss, avoids oxidation of metal contact surfaces, and extends the life of the connectors.

[0007] Preferably, the connecting assembly includes an arched connecting plate, with through rods fixedly connected to each of the four corners of the arched connecting plate. The through rods pass through through holes, and the arched connecting plate passes through a T-shaped connecting groove. By adopting the above technical solution, after the through rod is inserted into the through hole and the arched connecting plate is inserted into the T-shaped connecting groove, a rigid anchoring network can be formed under the action of the arched connecting plate and the through rod, which can disperse the stress of the wall and thus enhance the overall wind pressure resistance.

[0008] Preferably, both the through hole and the top of the T-shaped connecting groove are provided with an arc-shaped chamfer. By adopting the above technical solution and setting an arc-shaped chamfer, it is easier for people to connect the through rod with the through hole when the through rod is installed. This makes it easier for people to install the through rod, which helps to improve construction efficiency, reduce the difficulty of manual operation, and ensures a smoother and more accurate installation process.

[0009] Preferably, the top and bottom of the arched connecting plate are provided with arc-shaped chamfered corners, and the top and bottom of the through rod are provided with arc-shaped chamfered corners; By adopting the above technical solution and using the arc-shaped chamfered corner design, stress concentration-induced edge damage can be avoided when installing the through rod, thereby effectively extending the service life of the through rod and the arched connecting plate.

[0010] Preferably, the substrate is provided with a heat insulation layer, a heat insulation layer, a metal keel, a sound insulation layer and an outer protective layer; By adopting the above technical solutions and setting up insulation, heat insulation, sound insulation and outer protective layers, the requirements of energy saving, sound insulation, fire prevention and durability can be taken into account.

[0011] Preferably, the thermal insulation layer is disposed on the innermost layer, the heat insulation layer is disposed on the side of the thermal insulation layer, and the metal keel is disposed on the side of the heat insulation layer; By adopting the above technical solution, the inner insulation layer can block the leakage of indoor heat and prevent condensation. The heat insulation layer set on the outside of the insulation layer can preferentially reflect solar radiation and coordinate with ventilation and heat dissipation.

[0012] Preferably, the outer protective layer is disposed on the outermost layer, and the sound insulation layer is located between the outer protective layer and the metal keel; By adopting the above technical solutions and setting up a sound insulation layer, low- and mid-frequency noise can be absorbed, improving the acoustic environment. By setting up an outer protective layer, it can resist impact, prevent rainwater erosion, and protect the internal structure.

[0013] Preferably, the thermal insulation layer is made of vacuum insulation board, the heat insulation layer is made of aluminum foil composite board, the sound insulation layer is made of melamine foam, and the outer protective layer is made of fiber cement board. By adopting the above technical solutions, the heat conduction can be blocked and the indoor temperature can be kept stable under the action of the heat insulation layer, and the solar radiation heat can be reflected under the action of the heat insulation layer, which can reduce heat absorption in summer.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. This energy-saving building exterior wall structure with a ventilation and heat insulation layer forms a passive ventilation system by setting ventilation slots and guide fins. When air flows in the slots, the heat exchange area can be increased under the action of the guide fins, accelerating heat dissipation. In summer, the "chimney effect" can exhaust the hot air accumulated in the insulation layer. In winter, some ventilation openings can be closed to reduce cold air infiltration and balance the heat insulation requirements. By setting U-shaped connecting blocks, protrusions and grooves, modular rapid assembly of the wall can be achieved. The plug-in design of U-shaped connecting blocks and grooves, combined with the locking of protrusions, can ensure splicing accuracy, reduce on-site welding or bolt fixing procedures, and is simple to operate and has low operating costs. By setting T-shaped connecting grooves and graphene lubricating coating, the connecting components are guided to be inserted accurately. The graphene coating reduces friction loss, avoids oxidation of metal contact surfaces, and extends the life of the connectors.

[0015] 2. This energy-saving building exterior wall structure with a ventilation and heat insulation layer, through the design of curved chamfered corners, facilitates the connection between the through rod and the through hole during installation, thereby improving construction efficiency, reducing the difficulty of manual operation, and ensuring a smoother and more precise installation process. In addition, the curved chamfered corners can effectively reduce the friction between the through rod and the edge of the hole during installation, reducing the risk of material damage caused by friction, and thus extending the service life of the overall structure.

[0018] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0019] Example 1 Figure 2 and Figure 4 A type of energy-efficient building exterior wall structure with a ventilation and heat insulation layer, referring to Figure 1 The substrate 1 includes a substrate 1 and a connecting component 2. The substrate 1 has two through holes 8 on the top two sides and the bottom two sides. A T-shaped connecting groove 9 is provided between the two through holes 8. The connecting component 2 passes through the T-shaped connecting groove 9 of four adjacent substrates 1. The inner side of the T-shaped connecting groove 9 is coated with a graphene lubricating coating. The substrate 1 has a ventilation groove 3 inside, a connecting U-shaped groove 4 at the bottom of the ventilation groove 3, a U-shaped connecting block 6 fixedly connected to the top of the ventilation groove 3, grooves 5 on both sides inside the connecting U-shaped groove 4, protrusions 7 fixedly connected to both sides of the U-shaped connecting block 6, and multiple guide fins 301 on the inside side of the ventilation groove 3. By adopting the above technical solution, a passive ventilation system is formed by setting ventilation slots 3 and guide fins 301. When air flows in the slots, the heat exchange area can be increased under the action of guide fins 301, accelerating heat dissipation. In summer, the hot air accumulated in the insulation layer 102 can be discharged through the "chimney effect". In winter, some ventilation openings can be closed to reduce cold air infiltration and balance the insulation requirements. By setting U-shaped connecting blocks 6, protrusions 7 and grooves 5, modular rapid assembly of the wall can be achieved. The plug-in design of U-shaped connecting blocks 6 and grooves 5, together with the locking of protrusions 7, can ensure splicing accuracy, reduce on-site welding or bolt fixing procedures, and make operation simple and cost-effective. By setting T-shaped connecting grooves 9 and graphene lubricating coating, the connecting components 2 are guided to be inserted accurately. The graphene coating reduces friction loss, avoids oxidation of metal contact surfaces, and extends the life of the connectors.

[0020] Please see Figure 2 and Figure 3 The connecting component 2 includes an arched connecting plate 201, with through rods 202 fixedly connected to each of its four corners. The through rods 202 pass through through holes 8, and the arched connecting plate 201 passes through T-shaped connecting grooves 9. After the through rods 202 are inserted into the through holes 8 and the arched connecting plate 201 into the T-shaped connecting grooves 9, a rigid anchoring network is formed by the arched connecting plate 201 and the through rods 202. This network disperses wall stress and enhances the overall wind pressure resistance. Both the through holes 8 and the T-shaped connecting grooves 9 have concave arc angles 10 at their tops. These concave arc angles 10 help to prevent the through rods from passing through the wall. When the rod 202 is installed, it is convenient for people to connect the rod 202 with the through hole 8, which facilitates the installation of the rod 202, improves construction efficiency, reduces the difficulty of manual operation, and ensures a smoother and more accurate installation process. The top and bottom of the arched connecting plate 201 are provided with arc-shaped chamfered corners 203, and the top and bottom of the through rod 202 are also provided with arc-shaped chamfered corners 203. Through the design of the arc-shaped chamfered corners 203, when the through rod 202 is installed, it can avoid edge damage caused by stress concentration, thereby effectively extending the service life of the through rod 202 and the arched connecting plate 201.

[0021] Please see Figure 1 and Figure 5The substrate 1 contains an insulation layer 101, a heat insulation layer 102, a metal frame 103, a sound insulation layer 104, and an outer protective layer 105. By incorporating these layers, energy saving, sound insulation, fire resistance, and durability can be achieved. The insulation layer 101 is the innermost layer, the heat insulation layer 102 is located on the side of the insulation layer 101, and the metal frame 103 is located on the side of the heat insulation layer 102. The inner insulation layer 101 prevents heat loss and condensation, while the outer heat insulation layer 102 preferentially reflects solar radiation, coordinating with ventilation and heat dissipation, and providing external protection. The outermost protective layer 105 is located between the outer protective layer 105 and the metal keel 103. By setting the sound insulation layer 104, low- and mid-frequency noise can be absorbed, improving the acoustic environment. By setting the outer protective layer 105, it can resist impact and prevent rainwater erosion, protecting the internal structure. The thermal insulation layer 101 is made of vacuum insulation board, the thermal insulation layer 102 is made of aluminum foil composite board, the sound insulation layer 104 is made of melamine foam, and the outer protective layer 105 is made of fiber cement board. Under the action of the thermal insulation layer 101, heat conduction can be blocked, maintaining a stable indoor temperature. Under the action of the thermal insulation layer 102, solar radiation heat can be reflected, reducing heat absorption in summer.

[0022] The implementation principle of this application embodiment is as follows: When it is necessary to connect two substrates 1 left and right, people splice the two substrates 1 left and right. After the splicing is completed, people insert the connecting component 2 into the two T-shaped connecting grooves 9. After insertion, the two substrates 1 can be spliced ​​left and right. When splicing the substrates 1 up and down, the U-shaped connecting block 6 and the U-shaped groove can realize the rapid assembly of the upper and lower substrates 1. With the locking of the protrusion 7, the splicing accuracy can be ensured. After the splicing is completed, a passive ventilation system can be formed under the action of the ventilation groove 3 and the guide fin 301. When the air flows in the groove, the heat exchange area can be increased under the action of the guide fin 301, and the heat dissipation can be accelerated. In summer, the hot air accumulated in the heat insulation layer 102 can be discharged through the "chimney effect". In winter, some ventilation openings can be closed to reduce cold air infiltration and balance the heat preservation requirements.
