[0030] In order to make the utility model purposes, technical scheme and advantages more clear and obvious, the following specific embodiments shown in the drawings are used to describe the utility model.But it should be understood that these descriptions are only exemplary, and not to limit the scope of the utility model.In addition, in the following description, the description of known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0032] The utility model embodiments will be described in detail below with reference to the drawings.

[0033] Embodiment: as Figs. 1 to 4 The utility model discloses a kind of pre-buried components, for installation in structure main body 1, usually is pre-installed (buried) in concealed works component, these components are placed when structure pours, for the lapping when upper structure is built, and facilitate the installation and fixation of external engineering equipment foundation.Pre-buried in prior art, conventional steel embedment usually directly contact with main concrete, cannot realize energy-saving effect, especially in passive ultra-low energy consumption building, generally require that the heat transfer coefficient U value of transparent part does not exceed 1.0W / ㎡K, heat transfer coefficient reaches 8 level, for this energy-saving requirement, not only need front curtain wall system to meet energy-saving requirement, but also need embedment to participate in energy saving, the embedment in prior art is difficult to meet energy-saving requirement, affect use experience, not conducive to the promotion and application of above-mentioned embedment in curtain wall installation technical field.In order to solve the above technical problems, the pre-buried component in the embodiment is mainly composed of pre-buried piece 2 and heat insulation sleeve 3, that is, pre-buried piece 2 and heat insulation sleeve 3 are combined, which can effectively prevent heat loss at the pre-buried piece, thereby improving the overall thermal performance of the curtain wall, reducing the overall energy consumption of the building, enhancing the use experience, and facilitating the promotion and application of the above-mentioned pre-buried piece in the curtain wall installation technical field.

[0034] Specifically, the above-mentioned embedded part 2 includes an embedded main plate 2-1 and an embedded branch plate 2-2, both of which are made of steel plates. Due to the material properties of steel plate embedded parts, they have high strength and stability, can be used as connecting parts between concrete structures and steel structures, can bear various loads, and can transmit these forces to the concrete, thereby improving the stability and safety of the entire building structure. The embedded part can also disperse and bear stress, effectively prevent cracks and shedding of concrete, and also prevent corrosion of steel bars, thereby improving the durability of the building. The embedded branch plate 2-2 is two pieces, and the two pieces are arranged at an angle between the above-mentioned embedded main plate 2-1. Specifically, the angle can be designed as needed. In this embodiment, in order to reduce the probability of fracture at the connection between the embedded main plate 2-1 and the embedded branch plate 2-2, and to facilitate the installation of the heat insulation sleeve 3, the embedded main plate 2-1 and the embedded branch plate 2-2 are arranged vertically. The vertical arrangement can greatly reduce the installation resistance of the heat insulation sleeve 3 and improve the installation efficiency. In order to ensure the heat insulation effect at the embedded part, the heat insulation sleeve 3 passes through the embedded branch plate 2-2 and is sleeved outside the embedded main plate 2-1.

[0035] The heat insulation sleeve 3 is made of rigid polyurethane material. The main reason is that rigid polyurethane foam has a very low thermal conductivity, usually between 0.018 and 0.025 W / mK, which makes it one of the most effective thermal insulation materials. This low thermal conductivity helps to reduce heat loss and save energy. The closed cell rate of rigid polyurethane foam is as high as 95% or more, and it is a hydrophobic material that will not increase the thermal conductivity due to moisture absorption, and will not cause water seepage on the wall surface, and has good moisture and water resistance. After adding a flame retardant, rigid polyurethane foam is a self-extinguishing material that is difficult to burn, and the softening point can reach 250 degrees Celsius or more, and only at a higher temperature will it decompose. When burning, a carbonized layer will form on the surface of the foam, which helps to isolate the underlying foam and effectively prevent the spread of fire. Due to its excellent insulation properties, rigid polyurethane foam plays a crucial role in promoting energy efficiency and sustainable development by reducing heating and cooling energy consumption in buildings, refrigeration and transportation, which helps to reduce greenhouse gas emissions and energy costs. In order to further ensure the use effect, the heat insulation sleeve 3 is a semi-enclosed structure and covers the embedded main plate 2-1.

[0036] The pre-embedded main plate 2-1 and the heat insulation sleeve 3 are provided with fixing holes 4 corresponding to the positions of the pre-embedded main plate 2-1 and the heat insulation sleeve 3, which are fixed together. The fixing holes 4 are binding holes. By arranging the binding holes at the four corners of the pre-embedded main plate 2-1, corresponding binding holes are arranged at the four corners of the heat insulation sleeve 3, and the pre-embedded main plate 2-1 and the heat insulation sleeve 3 are tightly bound by a binding belt. The binding belt can ensure the fixation and positioning of the pre-embedded main plate 2-1 and the heat insulation sleeve 3 during construction, prevent displacement or deviation of them during concrete pouring, ensure the accurate position of the pre-embedded assembly, and further enhance the connection stability between the pre-embedded main plate 2-1 and the heat insulation sleeve 3, so that the connection between them is more firm and reliable during subsequent construction and use, thereby ensuring the use effect.

[0037] In order to further block heat loss and improve the overall thermal performance of the curtain wall, the fixing holes 4 can be filled with thermal insulation materials in the embodiment. The thermal insulation materials can be porous materials, heat reflective materials, vacuum materials or aerogels. Porous materials usually use the pores contained in the materials for heat insulation, because the thermal conductivity of air or inert gas in the voids is very low, such as foam materials and fiber materials. Heat reflective materials have a very high reflectivity and can reflect heat, such as gold, silver, nickel, aluminum foil or metal-coated polyester and polyimide film. Vacuum materials can block convection by using the internal vacuum of the material for heat insulation. Aerogels have extremely low thermal conductivity and can effectively block solid and gas conduction of heat, especially when the pore size is less than the infrared wavelength, the heat insulation effect will have a qualitative change and improvement. By filling the fixing holes 4 with thermal insulation materials, the heat loss can be further reduced, the energy efficiency and thermal insulation effect can be improved, the energy consumption can be reduced, and the cost can be reduced, especially in environments where temperature needs to be controlled.

[0038] The back of the pre-embedded main plate 2-1 is also provided with a cold bridge 5. In order to reduce the manufacturing cost, the cold bridge 5 can be designed as a semi-enclosed structure. The cold bridge 5 is also made of hard polyurethane material, thereby reducing heat loss and improving the thermal insulation performance and energy efficiency of the building. More preferably, the cold bridge 5 is provided in an open shape and the size of the opening is adapted to the thickness of the pre-embedded support plate 2-2, thereby ensuring the heat insulation effect at the connection of the pre-embedded assembly 1.

[0039] In order to ensure that the connection between the embedded branch plate 2-2 and the structure main body 1 is more firm, prevent the embedded part from loosening or falling off due to external force, and improve the stability and safety of the whole structure, a anti-falling part 2-3 is fixed on the top of the embedded branch plate 2-2 in the embodiment. The anti-falling part 2-3 is arranged in a bent shape, or other shaped anti-falling parts 2-3 are fixed on the top of the embedded branch plate 2-2 by welding. The anti-falling part 2-3 is mainly arranged to improve the stability and safety of the overall structure of the embedded assembly, and the specific shape is not limited here.

[0040] The pre-embedded assembly in the embodiment has a clever structure, and by arranging the embedded part 2 and the heat insulation sleeve 3, the heat insulation sleeve 3 is sleeved on the embedded part 2, that is, the embedded part 2 and the heat insulation sleeve 3 are combined, which can effectively prevent heat loss at the embedded part, thereby improving the overall thermal performance of the curtain wall, reducing the overall energy consumption of the building, enhancing the use experience, and being conducive to the promotion and application of the above-mentioned embedded part in the field of curtain wall installation.

[0041] The pre-embedded assembly in the embodiment can be applied to the installation of curtain walls and other occasions.
