Description
Technical Field
[0001] This invention belongs to the field of building technology, specifically relating to a green and energy-saving building exterior wall heat insulation and sound absorption structure and its construction method. Background Technology
[0002] With the acceleration of urbanization, building energy consumption has become an increasingly prominent issue. Traditional building exterior wall structures often suffer from poor thermal insulation, inadequate sound absorption, and inconsistent construction quality, making it difficult to meet the energy-saving, environmentally friendly, and comfortable requirements of modern green buildings. Furthermore, while foam materials (such as polystyrene foam and polyurethane foam) have good thermal insulation properties, they easily produce toxic gases when burned, posing safety hazards. At the same time, the recycling and disposal of foam materials are also difficult, hindering sustainable development. To address these issues, the construction industry has been continuously exploring new energy-saving materials and structural designs in recent years.
[0003] However, in existing technologies, the installation of exterior wall thermal insulation and sound absorption structures involves layer-by-layer installation, separating sound absorption and thermal insulation functions. This not only results in low installation efficiency but also high costs. Therefore, there is an urgent need for a simple, easy-to-install, and high-performance green and energy-saving building exterior wall thermal insulation and sound absorption structure and its construction method to meet the comprehensive requirements of modern buildings for energy conservation, environmental protection, and comfort. Summary of the Invention
[0004] To address the problems mentioned in the background art, the present invention provides a green and energy-saving building exterior wall thermal insulation and sound absorption structure, comprising:
[0005] The structure consists of a structural support layer, multiple layers of sound-absorbing materials, a heat insulation layer, and an environmentally friendly finishing layer, which are stacked sequentially from the inside out.
[0006] The multi-layer sound-absorbing material includes a honeycomb aluminum plate disposed on the inner side and a porous sound-absorbing plate disposed on the outer side.
[0007] Multiple connecting components are installed between the structural support layer and the porous sound-absorbing panel, and are distributed along the periphery of the honeycomb aluminum panel. Two adjacent connecting components can be interlocked with each other.
[0008] A fixed frame, in which the connecting member is slidably installed, is used to fix the overall structure to the exterior wall of the building.
[0009] Furthermore, the surface of the porous sound-absorbing plate is provided with multiple conical holes.
[0010] Furthermore, the two sides of the honeycomb aluminum plate are respectively fixedly connected to the structural support layer and the porous sound-absorbing plate.
[0011] Furthermore, the porous sound-absorbing panel is bonded to the heat insulation layer, and the heat insulation layer is bonded to the environmentally friendly decorative layer using an environmentally friendly adhesive.
[0012] Furthermore, the connecting member includes:
[0013] flat;
[0014] Two symmetrically arranged abutment plates are provided. A support plate is fixedly connected to the lower surface of the plate. A bidirectional screw is rotatably connected inside the support plate. The two ends of the bidirectional screw are threadedly connected to the two abutment plates respectively.
[0015] At least one pair of positioning plates are fixedly connected to the surface of the flat plate. The end of the positioning plate is provided with a protruding rod, and the positioning plates of adjacent connecting members can be interlocked with each other through the protruding rod.
[0016] Furthermore, a hexagonal head is fixedly connected to the bidirectional screw, and a notch is provided on the plate for the hexagonal head to be exposed.
[0017] Furthermore, the positioning plate is made of steel, and its tilt angle can be manually adjusted.
[0018] Furthermore, the surface of the fixed frame is provided with mounting holes for fixing to the wall.
[0019] Furthermore,
[0020] The porous sound-absorbing panel is made of sound-absorbing rock wool and recycled rubber particles;
[0021] The insulation layer is made of at least one of polystyrene foam, polyurethane foam, or phenolic foam.
[0022] The environmentally friendly finishing layer is a photocatalytic self-cleaning coating layer.
[0023] The construction method for the green and energy-saving building exterior wall thermal insulation and sound absorption structure, used for constructing the green and energy-saving building exterior wall thermal insulation and sound absorption structure as described in any one of the claims, includes the following steps:
[0024] S1: Prefabrication and Assembly
[0025] The structural support layer, multi-layer sound-absorbing material, heat insulation layer and environmentally friendly decorative layer are combined in sequence, and initially connected and fixed around the perimeter by connecting components to form a prefabricated panel unit;
[0026] S2: Adjustment and interlocking of connecting components
[0027] Adjust the connecting components so that their contact plates abut against the structural support layer and the porous sound-absorbing panel respectively to fix their positions; adjust the positioning plates of adjacent connecting components so that they interlock with each other through the protruding rods to achieve interlocking between adjacent precast panel units;
[0028] S3: Frame Installation and Fixing
[0029] Cut the fixed frame according to the dimensions of the exterior wall, and slide the assembled structure in step S into the fixed frame.
[0030] The structured fixed frame is attached to the exterior wall of the building and secured to the wall using fasteners through mounting holes.
[0031] A construction method for a green and energy-saving building exterior wall thermal insulation and sound-absorbing structure, including the aforementioned green and energy-saving building exterior wall thermal insulation and sound-absorbing structure, is as follows:
[0032] During construction, the bidirectional screw can be manually rotated by using a wrench with a hexagonal head, which facilitates the adjustment of the spacing of the symmetrical contact plates. This allows the symmetrical contact plates to contact the porous sound-absorbing panel and the structural support layer to the left and right respectively, thereby fixing the position of the connecting components. The tilt angle can be adjusted by manually pinching the positioning plate, which allows adjacent positioning plates to be interlocked through the protruding rods. This makes the adjacent heat insulation layer and environmentally friendly decorative layer form a plane, which helps to improve the aesthetics. In addition, the connecting components can be slidably connected to the fixed frame through the protruding rods, which helps to improve the flexibility of the overall panel installation.
[0033] The length of the fixed frame can be cut according to the area of the exterior wall. The final frame is located around the overall structure formed by the heat insulation and sound absorption structure of the green energy-saving building exterior wall and its construction method. It can play a supporting and fixing role. Holes are manually made in the wall, and the position of the holes corresponds to the installation holes. Expansion bolts can then be inserted into the manually made holes through the installation holes to fix the fixed frame.
[0034] The porous sound-absorbing panel is made of sound-absorbing rock wool and recycled rubber particles. It has good sound absorption performance and a certain degree of elasticity, which can effectively absorb and buffer sound. The heat insulation layer can be one or more of polystyrene foam board, polyurethane foam or phenolic foam. These materials have excellent heat insulation performance and can effectively block the transfer of external heat to the room. The environmentally friendly finishing layer is a photocatalytic self-cleaning coating layer with self-cleaning function, which can keep the exterior wall surface clean. At the same time, its photocatalytic effect can also purify the air to a certain extent, combining anti-fouling and air purification functions.
[0035] Compared with the prior art, the beneficial effects of the present invention are:
[0036] This green and energy-saving building exterior wall heat insulation and sound absorption structure and its construction method, in actual use, first block external heat through the heat insulation layer. The heat insulation layer reflects and blocks heat, reducing the transfer of heat into the room, thereby maintaining a stable indoor temperature and reducing the frequency of use of air conditioning and other equipment, achieving energy-saving effects. When external noise or noise generated indoors is transmitted, the conical holes on the surface of the porous sound-absorbing panel can effectively reduce sound reflection. After the sound enters the interior of the porous sound-absorbing panel, it is absorbed by the sound-absorbing rock wool and recycled rubber particles. At the same time, the special structure of the honeycomb aluminum panel can also reflect and absorb sound. The combined effect of the two greatly improves the sound absorption effect, creating a quiet and comfortable indoor environment. The layers are bonded with environmentally friendly adhesives, which not only ensures the tightness of the connection but also meets environmental protection requirements. The design of the connecting components and fixing frame makes the entire structure more convenient to install. Adjacent connecting components can be interlocked, improving installation efficiency and stability, and also facilitating later maintenance and replacement. Attached Figure Description

[0052] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0053] Example
[0054] Please see Figure 1-6 The present invention provides the following technical solution: a green and energy-saving building exterior wall heat insulation and sound absorption structure and its construction method, comprising:
[0055] The structure consists of, from the inside out, a structural support layer 1, multiple layers of sound-absorbing material 2, a heat insulation layer 3, and an environmentally friendly finishing layer 4;
[0056] The multi-layer sound-absorbing material 2 includes a porous sound-absorbing panel 201 and a honeycomb aluminum panel 202, with the porous sound-absorbing panel 201 located in front of the honeycomb aluminum panel 202.
[0057] Connecting components 5 are installed between the structural support layer 1 and the porous sound-absorbing panel 201. Four of them are located on the upper, lower, left and right sides of the honeycomb aluminum panel 202 respectively. Two adjacent connecting components 5 can be fastened together.
[0058] The fixed frame 6 and the connecting component 5 are slidably installed inside the fixed frame 6.
[0059] Furthermore, the holes on the surface of the porous sound-absorbing panel 201 are tapered circular holes.
[0060] The technical solution provided by this invention, in actual use, first blocks external heat by the heat insulation layer 3, which reflects and blocks heat, reducing the transfer of heat to the room, thereby maintaining a stable indoor temperature, reducing the frequency of use of air conditioning and other equipment, and achieving energy saving. When external noise or indoor noise propagates, the conical holes on the surface of the porous sound-absorbing panel 201 can effectively reduce sound reflection, so that the sound is absorbed by the sound-absorbing rock wool and recycled rubber particles after entering the porous sound-absorbing panel 201. At the same time, the special structure of the honeycomb aluminum panel 202 can also reflect and absorb sound. The two work together to greatly improve the sound absorption effect and create a quiet and comfortable indoor environment. The layers are bonded with environmentally friendly adhesives, which not only ensures the tightness of the connection but also meets environmental protection requirements. The design of the connecting components 5 and the fixing frame 6 makes the entire structure more convenient to install. Adjacent connecting components 5 can be snapped together, improving installation efficiency and stability, and also facilitating later maintenance and replacement.
[0061] Furthermore, the two sides of the honeycomb aluminum panel 202 are fixedly connected to the structural support layer 1 and the porous sound-absorbing panel 201, respectively.
[0062] Specifically, this helps ensure the overall stability of the multi-layer sound-absorbing material 2.
[0063] Furthermore, the porous sound-absorbing panel 201 is bonded to the heat insulation layer 3, and the heat insulation layer 3 is bonded to the environmentally friendly decorative layer 4 using environmentally friendly adhesives.
[0064] Specifically, this ensures that the connections between each layer are tight and environmentally friendly with no pollution.
[0065] Furthermore, the connecting member 5 includes:
[0066] The plate 501 and the contact plate 502 are provided. A support plate 503 is fixedly connected to the lower surface of the plate 501. A bidirectional screw 504 is rotatably connected inside the support plate 503. A hexagonal head 505 is fixedly connected to the surface of the bidirectional screw 504. A notch 506 is provided on the surface of the plate 501. The contact plates 502 are symmetrically arranged, and the bidirectional screw 504 is threadedly connected to the symmetrical contact plates 502 respectively. A positioning plate 507 is fixedly connected to the surface of the plate 501. The positioning plate 507 is made of steel and can be manually adjusted by pinching. It is symmetrically distributed. A protruding rod 508 is fixedly connected to the end of the positioning plate 507. The connecting components 5 that are adjacent vertically or horizontally can be fastened together through the protruding rod 508.
[0067] Specifically, by using a wrench on the hexagonal head 505, the bidirectional screw 504 can be manually rotated, which facilitates the adjustment of the spacing of the symmetrical contact plates 502. This allows the symmetrical contact plates 502 to contact the porous sound-absorbing panel 201 and the structural support layer 1 to the left and right respectively, thereby fixing the position of the connecting component 5. The tilt angle can be adjusted by manually pinching the positioning plate 507, which facilitates the interlocking of adjacent positioning plates 507 on the top and bottom or left and right through the protruding rod 508. This makes the adjacent heat insulation layer 3 and environmentally friendly decorative layer 4 form a plane, which helps to improve the aesthetics. In addition, the connecting component 5 can be slidably connected to the fixed frame 6 through the protruding rod 508, which helps to improve the flexibility of the overall panel installation.
[0068] Furthermore, mounting holes 7 are provided on the surface of the fixed frame 6.
[0069] Specifically, the length of the fixed frame 6 can be cut according to the area of the exterior wall. The final frame is located around the overall structure formed by the heat insulation and sound absorption structure of the green energy-saving building exterior wall and its construction method. It can play a supporting and fixing role. Holes are manually made in the wall, and the position of the holes corresponds to the installation holes 7. Then, expansion screws can be inserted into the manually made holes through the installation holes 7 to fix the fixed frame 6.
[0070] Furthermore, the porous sound-absorbing panel 201 is composed of sound-absorbing rock wool and recycled rubber particles, the heat insulation layer 3 can be one or more of polystyrene foam board, polyurethane foam or phenolic foam, and the environmentally friendly finishing layer 4 is a photocatalytic self-cleaning coating layer.
[0071] Specifically, the porous sound-absorbing panel 201 is composed of sound-absorbing rock wool and recycled rubber particles, which has good sound absorption performance and a certain degree of elasticity, and can effectively absorb and buffer sound. The heat insulation layer 3 can be one or more of polystyrene foam board, polyurethane foam or phenolic foam. These materials have excellent heat insulation performance and can effectively block the transfer of external heat to the room. The environmentally friendly finishing layer 4 is a photocatalytic self-cleaning coating layer with self-cleaning function, which can keep the exterior wall surface clean. At the same time, its photocatalytic effect can also purify the air to a certain extent, combining anti-fouling and air purification functions.
