Description

A prefabricated component that meets the thermal insulation requirements of zero-carbon buildings Technical Field

[0001] This application relates to the technical field of prefabricated building connectors, and in particular to a prefabricated component that meets the thermal insulation requirements of zero-carbon buildings. Background Technology

[0002] In modern building engineering, thermal insulation technology is commonly used on the exterior of buildings to achieve heat insulation effects, thereby improving the building's energy efficiency and indoor environmental comfort. However, in actual building construction, thermal bridges often occur in areas such as balcony handrails, roof equipment foundations, cantilevered canopies, air conditioner outdoor unit brackets, or connections to large or heavy equipment, where thermal bridges penetrate the insulation layer. These areas usually require pre-embedding or drilling during construction to achieve a fixed connection.

[0003] In related technologies, conventional connection structures mostly use conventional steel or similar embedded components. On the one hand, due to the good thermal conductivity of metal materials, heat inside the building can be quickly conducted to the outside through these connection components, resulting in a large amount of heat loss. This not only reduces the thermal insulation effect but also increases building energy consumption, which is not conducive to the building's energy-saving requirements. On the other hand, embedded metal components may pose a risk of electrical conductivity under certain specific environments, which may lead to safety accidents and pose a potential threat to the life and property safety of building users. Summary of the Invention

[0004] In order to block thermal bridges, reduce heat loss from buildings, and improve safety, this application provides a prefabricated component that meets the thermal insulation requirements of zero-carbon buildings.

[0005] This application provides a prefabricated component that meets the thermal insulation requirements of zero-carbon buildings, employing the following technical solution:

[0006] A prefabricated component meeting the thermal insulation requirements of zero-carbon buildings includes a prefabricated component with thermal insulation and electrical insulation effects, which is fixedly connected to the outside of a concrete layer. The prefabricated component includes a cover plate, a fixing plate, a rigid thermal insulation layer, and a connecting pipe. The rigid thermal insulation layer abuts against the outside of the concrete layer, and the cover plate abuts against the end of the rigid thermal insulation layer away from the concrete layer. The fixing plate is pre-embedded in the rigid thermal insulation layer during its casting. One end of the connecting pipe is fixedly connected to the fixing plate, and the other end of the connecting pipe is used for fixed connection to outdoor lightweight components, large or heavy equipment.

[0007] By adopting the above technical solution, the connecting pipe and the fixing plate are fixedly connected. The fixing plate is embedded in the rigid insulation layer. The rigid insulation layer blocks the heat transfer between the connecting pipe and the concrete layer, reduces the thermal bridge effect, and thus reduces the heat loss of the building. It also has a low risk of electrical conductivity and high safety in use. At the same time, the pre-embedding method makes the connection strength between the fixing plate and the rigid insulation layer good. Furthermore, the prefabricated component is a whole, which only requires simple installation during use, improving construction efficiency.

[0008] Optionally, the cover plate includes a top plate and side plates, with multiple side plates fixed to the periphery of the top plate; the top plate abuts against the end of the rigid insulation layer away from the concrete layer, and the side plates abut against the periphery of the rigid insulation layer; a connecting hole is provided on the top plate, and an installation hole is pre-reserved at the end of the rigid insulation layer near the top plate during casting; the axes of the connecting hole and the installation hole are on the same straight line and connected; the end face of the installation hole away from the connecting hole abuts against a fixing plate, and the connecting pipe extends into the connecting hole and is fixedly connected to the fixing plate.

[0009] By adopting the above technical solution, the top plate and side plate are wrapped on top of the rigid insulation layer, which can reduce the displacement or shaking of the prefabricated components during use, thereby enhancing the structural stability and deformation resistance of the prefabricated components; the setting of mounting holes and connection holes makes the installation of connecting pipes more convenient and precise.

[0010] Optionally, the precast component is provided with a number of expansion bolts, which pass through the top plate, the fixing plate and the rigid insulation layer in sequence and are fixed in the concrete layer; the end of the connecting pipe away from the fixing plate is used for fixed connection with the outdoor lightweight component.

[0011] By adopting the above technical solution, the precast components are fixed to the outside of the concrete layer with expansion bolts, which meets the requirements for fixed connection of outdoor lightweight components. At the same time, expansion bolts are easy to use and have low cost.

[0012] Optionally, the end face of the rigid insulation layer away from the top plate is higher than the end face of the side plate away from the top plate.

[0013] By adopting the above technical solution, the end face of the rigid insulation layer is higher than the end face of the side panel, avoiding direct contact between the side panel and the concrete layer, which helps to reduce heat conduction, reduce the risk of electrical conductivity, and improve safety in use.

[0014] Optionally, a sealant layer is provided between the connecting pipe and the wall of the mounting hole.

[0015] By adopting the above technical solution, the sealant layer helps reduce the damage of moisture and other substances to the rigid insulation layer and fixing plate, while reducing air flow and further improving the insulation effect.

[0016] Optionally, embedded parts are pre-embedded in the concrete layer, and the precast parts are fixedly connected to the embedded parts; the end of the connecting pipe away from the fixed plate is used for fixed connection with large or heavy equipment.

[0017] By adopting the above technical solution, the embedded parts are embedded in the concrete layer, which makes the connection strength between the precast parts and the concrete layer high, meeting the needs of fixed connection of large or heavy outdoor equipment.

[0018] Optionally, the embedded component includes a connecting plate and embedded reinforcing bars, the embedded reinforcing bars are welded to the connecting plate, and the end of the embedded reinforcing bars away from the connecting plate is bent; the end of the connecting plate away from the embedded reinforcing bars is fixedly connected to the end of the precast component away from the connecting pipe.

[0019] By adopting the above technical solution, the connecting plate and the embedded steel bars are connected by welding, resulting in good connection strength. The bending of the embedded steel bars helps to reduce the risk of the embedded steel bars slipping or being pulled out in the concrete layer, thereby enhancing the stability and safety of the overall structure.

[0020] Optionally, the connecting plate is welded to the side plate.

[0021] By adopting the above technical solution, the end faces of the connecting plate and the side plate are welded together, further enhancing the connection strength.

[0022] Optionally, an installation plate is fixedly connected to the end of the connecting pipe away from the fixed plate, and a concrete foundation is poured for the end of the installation plate away from the connecting pipe. An external connecting pipe is fixedly connected to the concrete foundation, and the external connecting pipe is used for fixed connection with large or heavy equipment.

[0023] By adopting the above technical solutions, the setting of concrete foundations further enhances the connection strength, making the reliability and safety of fixed connections for large or heavy equipment better.

[0024] Optionally, a first stiffening rib is provided at the connection between the connecting pipe and the fixing plate. The first stiffening rib is welded to the connecting pipe and the fixing plate respectively. The first stiffening rib is pre-embedded in the rigid insulation layer during the casting process of the rigid insulation layer.

[0025] By adopting the above technical solution, the first stiffening rib is used to further improve the connection strength between the connecting pipe and the fixing plate, so that the connection strength of the prefabricated component is better and the firmness is better when connecting large or heavy outdoor equipment.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Precast components have a thermal insulation effect, blocking heat transfer between lightweight outdoor components, large or heavy equipment and the concrete layer, effectively reducing the thermal bridging effect, thereby reducing heat loss from the building and reducing the risk of electrical conductivity, resulting in high safety in use; moreover, as a whole, precast components only require simple installation during use, improving construction efficiency.

[0028] 2. When connecting outdoor lightweight components, the precast components are fixed to the outside of the concrete layer with expansion bolts, which is convenient to use;

[0029] 3. When connecting large or heavy outdoor equipment, the precast components are pre-embedded in the concrete layer, and then connected to the precast components, thereby fixing the precast components to the outside of the concrete layer. The connection strength can be further enhanced by setting up installation plates and concrete foundations, etc., to meet the needs of fixing large or heavy outdoor equipment.

[0039] Example 1

[0040] Embodiment 1 of this application discloses a prefabricated component that meets the thermal insulation requirements of zero-carbon buildings. Referring to Figure 1, it includes a prefabricated component 1 with thermal insulation and electrical insulation effects and expansion bolts 2. The expansion bolts 2 pass through the prefabricated component 1 and are fixed in the concrete layer 4, so that the prefabricated component 1 abuts against the outside of the concrete layer 4. The end of the prefabricated component 1 away from the concrete layer 4 is used for fixed connection with outdoor lightweight components such as balcony handrails, roof equipment foundations, cantilevered canopies, and air conditioner outdoor unit brackets.

[0041] In use, the precast component 1 is fixed to the concrete layer 4 using expansion bolts 2. Then, an inner waterproof layer 5, a thermal insulation layer 6, an outer waterproof layer 8, and a protective layer 7 are laid sequentially on the outside of the concrete layer 4, embedding the precast component 1 in the building roof. One end of the precast component 1 extends from the building roof for connection with the outdoor lightweight components. The precast component 1 has a heat insulation effect, thereby blocking heat transfer between the outdoor lightweight components and the concrete layer 4, reducing the thermal bridging effect, and thus reducing heat loss from the building. Furthermore, the precast component 1 has an insulating effect, reducing the risk of electrical conductivity and ensuring high safety in use.

[0042] The precast component 1 includes a cover plate 11, a fixing plate 12, a rigid insulation layer 13, and a connecting pipe 14. The rigid insulation layer 13 is cuboid and abuts against the outside of the concrete layer 4. The cover plate 11 abuts against the end of the rigid insulation layer 13 away from the concrete layer 4. The fixing plate 12 is horizontally fixed in the rigid insulation layer 13. The fixing plate 12 is pre-embedded in the rigid insulation layer 13 during the casting process. The connecting pipe 14 is fixedly connected to the fixing plate 12.

[0043] Referring to Figures 2 and 3, the cover plate 11 includes a top plate 111 and four side plates 112. The top plate 111 has a rectangular plate structure, and the four side plates 112 are respectively vertically fixed to the periphery of the top plate 111, with the side walls of adjacent side plates 112 connected. The top plate 111 and the four side plates 112 are integrally formed. The top plate 111 abuts against the end of the rigid insulation layer 13 away from the concrete layer 4, and the inner side of the side plates 112 abuts against the periphery of the rigid insulation layer 13. In this embodiment, the height of the rigid insulation layer 13 is greater than the height of the side plates 112 during casting, thereby avoiding direct contact between the side plates 112 and the concrete layer 4, which helps to reduce heat conduction.

[0044] A rectangular connecting hole 113 is provided in the center of the top plate 111. A rectangular mounting hole 131 is pre-drilled at one end of the rigid insulation layer 13 near the cover plate 11 during casting. The axes of the connecting hole 113 and the mounting hole 131 are on the same straight line. The connecting hole 113 and the mounting hole 131 are connected, and the end face of the mounting hole 131 away from the connecting hole 113 abuts against the end face of the fixing plate 12. A connecting pipe 14 extends from the connecting hole 113 to the end face of the fixing plate 12, and the connecting pipe 14 and the fixing plate 12 are connected by welding. The connection strength is good, and the tensile and torsional strengths meet the requirements for connecting outdoor lightweight components. In this embodiment, the connecting pipe 14 is a galvanized square tube, the fixing plate 12 is a steel plate, and the rigid insulation layer 13 is made of epoxy fiberglass resin, carbon fiber, or other high-strength new materials that meet the requirements for heat insulation and electrical insulation.

[0045] When preparing precast component 1, the fixing plate 12 and the connecting pipe 14 are first welded together. Then, the connecting pipe 14 is passed through the connecting hole 113 on the top plate 111, and the fixing plate 12 is located inside the cover plate 11 with a gap between it and the top plate 111. Then, the rigid heat insulation layer 13 is poured. After the rigid heat insulation layer 13 solidifies, the preparation of precast component 1 is completed.

[0046] A sealant layer 16 is provided between the connecting pipe 14 and the hole wall of the mounting hole 131 to reduce the damage of moisture and other substances to the rigid insulation layer 13 and the fixing plate 12, while reducing air flow and further improving the heat insulation effect of the prefabricated component 1.

[0047] There are four expansion bolts 2, which are evenly distributed at the four corners of the cover plate 11.

[0048] The implementation principle of a prefabricated component that meets the thermal insulation requirements of zero-carbon buildings, as disclosed in Embodiment 1 of this application, is as follows: First, the prefabricated component 1 is prefabricated. Then, the expansion bolts 2 are passed through the top plate 111, the rigid insulation layer 13, and the fixing plate 12 in sequence and into the concrete layer 4 to firmly fix the prefabricated component 1 to the concrete layer 4. Then, from bottom to top, the inner waterproof layer 5, the thermal insulation layer 6, the outer waterproof layer 8, and the protective layer 7 are laid in sequence. Outdoor lightweight components such as balcony handrails, roof equipment foundations, cantilevered canopies, and air conditioner outdoor unit brackets are fixedly connected to the end of the connecting pipe 14 away from the fixing plate 12 to achieve thermal insulation connection of outdoor lightweight components, effectively reduce the loss of building heat, and have high safety in use.

The end of the connecting plate 31 away from the embedded reinforcing bar 32 extends from the concrete layer 4 and is fixedly connected to the end of the side plate 112 away from the top plate 111; the end face of the connecting plate 31 is flush with the end face of the concrete layer 4.
