Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a prefabricated component for thermal insulation and soundproofing prefabricated exterior wall panels. Background Technology

[0002] With the rapid development of the construction industry, the performance requirements for building exterior wall panels are becoming increasingly stringent. Thermal insulation and sound insulation, as crucial performance indicators for building exterior wall panels, directly impact the energy efficiency of buildings and the comfort of residents. Traditional exterior wall panels often have limitations in terms of thermal insulation and sound insulation, making it difficult to meet the demands of modern buildings for energy conservation, environmental protection, and a high-quality living environment. Prefabricated construction, as a new construction method, offers advantages such as high construction efficiency and controllable quality, and prefabricated exterior wall panels are a key component of prefabricated buildings. Therefore, developing prefabricated exterior wall panel components with excellent thermal insulation and sound insulation performance is of significant practical importance.

[0003] However, existing equipment, due to its use of only conventional single insulation material and simple sound insulation structure, suffers from relatively high thermal conductivity. Heat is easily conducted through the exterior wall panels, leading to rapid heat exchange between indoors and outdoors and difficulty in effectively maintaining stable indoor temperature. The simple sound insulation structure has limited ability to block external noise, especially low-frequency noise and traffic noise with strong penetrating power, making it difficult to provide effective sound insulation. Therefore, we propose a more convenient and practical prefabricated exterior wall panel component with thermal insulation and sound insulation to meet the usage requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated exterior wall panel component with thermal insulation and sound insulation properties to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated exterior wall panel component with thermal insulation and soundproofing, comprising a structural layer and a protective layer; the structural layer includes a steel frame welded together from a fixing plate, a longitudinal reinforcing plate, and a transverse reinforcing plate, wherein longitudinal and transverse reinforcing bars are fixedly connected to one side of the longitudinal and transverse reinforcing plates and concrete is poured to form the structure; the protective layer includes a heat insulation layer, an adhesive layer is bonded to one side of the heat insulation layer, a sound insulation layer is bonded to one side of the adhesive layer, and a number of equidistant mounting grooves are provided on the top of the sound insulation layer, each mounting groove containing an independent sound insulation block.

[0006] Furthermore, the fixing plate is a precast reinforced concrete slab, and the longitudinal and transverse reinforcing plates are channel steel or cold-formed steel, which are connected to the fixing plate by embedded parts or high-strength bolts.

[0007] Furthermore, a transverse heat insulation strip and a longitudinal heat insulation strip are fixedly connected to one side of the heat insulation layer. The transverse heat insulation strip and the longitudinal heat insulation strip are made of high-density polyurethane foam material, and the two form a three-dimensional mesh heat insulation barrier inside the heat insulation layer.

[0008] Furthermore, the sound insulation block is made of either a cube or a cylinder component made of closed-cell aluminum foam material and is adapted to fit the mounting groove.

[0009] Furthermore, a heat insulation layer and an outer layer are sequentially fixedly connected to one side of the sound insulation layer.

[0010] Furthermore, the insulation layer is made of a composite structure of vacuum insulation board and graphite polystyrene foam board.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This prefabricated exterior wall panel, featuring thermal insulation and soundproofing, utilizes a structural layer and a protective layer. During use, the thermal insulation layer forms a three-dimensional mesh barrier internally through horizontal and vertical thermal insulation strips, preferentially blocking heat conduction caused by temperature differences between indoors and outdoors. The sound insulation layer then forms a sound-absorbing structure through sound-absorbing blocks within the installation groove. When external sound waves reach the sound insulation layer, the porous nature of the sound-absorbing blocks converts sound energy into heat energy and scatters it, reducing noise penetration. Subsequently, the thermal insulation layer further enhances the thermal insulation effect, while the outermost layer acts as the outermost protection, resisting environmental erosion such as wind, rain, and ultraviolet rays. This exterior wall panel effectively blocks the intrusion of external noise, providing a quiet indoor environment. It is highly practical and suitable for widespread adoption.

[0013] At the same time, it reduces the exchange of heat between indoors and outdoors, lowers the building's energy consumption, and plays a good role in thermal insulation. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] During building construction, exterior wall panels are required. The exterior wall panels provided by this utility model are specifically designed for use during building construction. When using them, the exterior wall panels should be stored in a dry, ventilated, and flat location, avoiding damp or waterlogged areas to prevent the panels from becoming damp, moldy, and corroded. The storage location must have sufficient load-bearing capacity to support the weight of the exterior wall panels. Before installing the exterior wall panels, the building substrate must be cleaned and treated to ensure that the substrate surface is flat, clean, free of oil stains, and free of debris. When installing the exterior wall panels, the design requirements and installation process must be strictly followed to ensure that the connection between the exterior wall panels and the main building structure, as well as between adjacent exterior wall panels, is firm and reliable.

[0020] like Figures 1-3 As shown, this utility model provides a technical solution: a prefabricated exterior wall panel component with thermal insulation and soundproofing, including a structural layer 1 and a protective layer 2; the structural layer 1 includes a steel frame welded together from a fixing plate 101, a longitudinal reinforcing plate 102, and a transverse reinforcing plate 103, with longitudinal reinforcing bars 104 and transverse reinforcing bars 105 fixedly connected to one side of the longitudinal reinforcing plate 102 and the transverse reinforcing plate 103, and formed by pouring concrete; the protective layer 2 includes a heat insulation layer 201, with an adhesive layer 204 bonded to one side of the heat insulation layer 201, and a sound insulation layer 205 bonded to one side of the adhesive layer 204, with several equidistant mounting grooves 206 on the top of the sound insulation layer 205, each mounting groove 206 having an independent sound insulation block 207 embedded in it, the fixing plate 101 being a prefabricated reinforced concrete slab, and the longitudinal reinforcing plate 102 and the transverse reinforcing plate 103 being channel steel or cold-formed steel, and connected to the fixing plate 101 by embedded parts or high-strength bolts.

[0021] It should be noted that during use, the fixing plate 101 is welded to the longitudinal reinforcing plate 102 and the transverse reinforcing plate 103 through embedded parts or high-strength bolts to form a steel frame. Then, the longitudinal reinforcing bars 104 and the transverse reinforcing bars 105 are fixed to the reinforcing plates, and concrete is poured to wrap the reinforcing bars and reinforcing plates. This allows the concrete, reinforcing bars, and steel frame to share the load, which can effectively resist the external forces on the exterior wall panel in the horizontal and vertical directions, such as wind force and seismic force, ensuring the structural stability of the exterior wall panel under different stress conditions and reducing the risk of deformation and damage.

[0022] like Figure 3As shown, a transverse heat insulation strip 202 and a longitudinal heat insulation strip 203 are fixedly connected to one side of the heat insulation layer 201. The transverse heat insulation strip 202 and the longitudinal heat insulation strip 203 are made of high-density polyurethane foam material, and the two form a three-dimensional mesh heat insulation barrier inside the heat insulation layer 201. The sound insulation block 207 is made of either a cube or a cylinder component made of closed-cell aluminum foam material, and is adapted to the mounting groove 206. A thermal insulation layer 208 and an outer layer 209 are fixedly connected to one side of the sound insulation layer 205 in sequence. The thermal insulation layer 208 is made of a composite structure of vacuum insulation board and graphite polystyrene foam board.

[0023] It is important to note that during use, the thermal insulation layer 201 forms a three-dimensional mesh barrier internally through the horizontal thermal insulation strips 202 and the vertical thermal insulation strips 203, which preferentially blocks heat conduction caused by temperature differences between the indoor and outdoor areas. Then, the sound insulation layer 205 forms a sound-absorbing structure through the sound insulation blocks 207 in the mounting groove 206. When external sound waves are transmitted to the sound insulation layer 205, the porous nature of the sound insulation blocks 207 converts sound energy into heat energy and scatters it, reducing noise penetration. Subsequently, the thermal insulation layer 208 further enhances the thermal insulation effect, while the outer layer 209, as the outermost protection, resists environmental erosion such as wind, rain, and ultraviolet rays. This exterior wall panel can effectively block the entry of external noise, providing a quiet environment for the interior, while reducing the exchange of heat between the indoor and outdoor areas, reducing the building's energy consumption, and playing a good role in thermal insulation.

[0025] In order to improve the quality and performance of a newly built high-rise residential building in a certain city, prefabricated exterior wall panels with thermal insulation and soundproofing were adopted.

[0026] In the early stages of construction, precast components are produced in the factory according to design standards. The fixing plate 101 of structural layer 1 is made of high-quality reinforced concrete precast plate, which is precisely cast in the mold in the factory. The longitudinal reinforcing plate 102 and the transverse reinforcing plate 103 are made of high-strength channel steel and are firmly connected to the fixing plate 101 through welding process. Then, the longitudinal reinforcing bars 104 and transverse reinforcing bars 105 are precisely fixed and connected on one side, and then high-quality concrete is poured.

[0027] The heat insulation layer 201, horizontal heat insulation strip 202, and vertical heat insulation strip 203 of the protective layer 2 are made of high-density polyurethane foam material, forming a three-dimensional mesh heat insulation barrier in the factory, and then composite molded with the heat insulation board. During the production of the sound insulation layer 205, equidistant mounting grooves 206 are opened on the top, and the sound insulation blocks 207 made of closed-cell foam aluminum material are precisely embedded in the mounting grooves 206. The thermal insulation layer 208 adopts a composite structure of vacuum insulation board and graphite polystyrene foam board, and is tightly bonded to the sound insulation layer 205 through professional bonding process. The outer layer 209 is made of board material with good weather resistance.
